I. Purpose of the internship:
The internship is mainly a combination of theory and practice, a better understanding of the theory, so that the theory learned on the course to the actual use of the theory.
Second, the internship unit and job description:
Internship we mainly visited four companies in the production line. Through the explanation of the person in charge of each company, understand the development of each of the four companies and the development of the technology of their production products.
Third, internship arrangements:
Four days of internship is mainly in the morning in the school mass classes, the old are quite experienced in the work of seniors. Afternoon mass organization mainly in Qixia District, an industrial park to visit the production line.
Fourth, the internship information and process:
In just four days I learned the school can not understand the knowledge, but also the specialty is rarely involved in the part. There are two main parts, one is: the theory and technology of the printer, and the other is: the production and processing of circuit boards.
Through the morning of Mr. Li and Mr. Zhang's theoretical teaching, to understand the printer's five classifications, as well as the popular three-dimensional printers, feel really amazing, a printer can be a car model out of the writer Su Tong's classic: how far the idea, how far we can go. Life can not do, only can not think of, but think of can not do and do well, but also realistic, according to resources, demand, technology and other aspects of the requirements of the combination of very good, that is, even if it is done. Then is the classification of pcb circuit boards, according to different ways of categorizing different classifications. Mainly according to the material, processing technology classification. According to the teacher said according to the material is divided into five kinds, paper, epoxy, fiberglass, polyoxyethylene and ceramic. According to the processing technology and have different classifications, processing technology is mainly based on its development process of different technologies. Then is the basic principle of microcontroller and printer development and classification.
During the visit, we learned the importance of the process, and the impact of process technology on the product. In the Zijin Machinery Electronic Equipment Factory we visited the printer's production department. Inside also saw the most advanced three-dimensional printer, although it is through the glass to see, but obviously feel the importance of technology, how our country does not have the kind of advanced vision of foreign countries, this idea is in the technicians to us that the glass inside the three-dimensional printer is introduced from abroad, looking at foreign do not understand is the technician or what, inside the strict look, a profound feeling that no matter what, we All need to have their own things, their own characteristics. After visiting the factory to see the production line of the pcb board, as well as mounted parts of the pcb board production line, each process determines the quality of a product. Because each step in the production process plays a decisive role, so each one is the most important.
V. Internship summary and experience:
A short four-day production internship is over, the feeling is quite deep. Production must be combined with the actual, not only to have the technology, but also to have the appearance. There is technology but also fast, to update the fast; have the appearance but also unique, is to sell, unique so that people can not be completely imitated. And I think that even when writing software, to think about these programs to give in software and hardware how to better combine, better combined with how to facilitate the actual thing, so that people look comfortable, do not write the program is to write the program, we should be written for us to use the customer to think about, of course, but also combined with the actual cost savings.
In short, the product must be combined with the market production. Internship time is short, but learned something real, the heart is very grateful to the school.
Second
Introduction
XX year xx month 23rd xx year xx month 24th, we visited xxxxxx Co. After a personal visit to the factory and workshop, I have a further understanding of my major; so that I initially understand the common textiles processed in the printing and dyeing plant; at the same time, our lead teacher also explained to us a lot of dyeing and finishing process and the specific process conditions required in the process, the basic equipment. Through this time, I not only enhanced the theoretical level, but also improved my potential to use theoretical knowledge to solve the actual production problems.
After the completion of the internship, I searched and consulted the relevant information to deepen the understanding of professional knowledge, and specific understanding of several types of textile dyeing and finishing process, a preliminary understanding of the basic process of rolling and dyeing. Below I will cite the cotton fabric ginning and dyeing and silk printing processing two examples to analyze.
The basic fabric dyeing process
The fabric dyeing method is mainly divided into dip-dyeing and roll-dyeing. Dip-dyeing is the fabric impregnated in the dye solution, so that the dye gradually on the fabric dyeing method, which is suitable for small quantities of many varieties of dyeing. Rope dyeing, roll dyeing belongs to this category. Rolling dyeing is the first fabric impregnated in the dye solution, and then make the fabric through the rollers, the dye solution evenly rolled into the fabric, and then by steam or heat fusion and other processing of the dyeing method, which is suitable for large quantities of fabric dyeing. Dyeing is carried out under the conditions of necessary temperature, time, ph value and required dyeing auxiliaries. Dyes used for dyeing cotton fabrics are mainly direct dyes, reactive dyes, reducing dyes, soluble reducing dyes, insoluble azo ammonia dyes, sulfur dyes and so on.
Shaoxing Zhiren Printing and Dyeing Factory is mainly on the cotton and linen, viscose fabrics dyeing to ginning and dyeing, while Hangzhou Huatai Silk Printing and Dyeing Group is mainly on the printing of silk fabrics.
Cotton fabrics ginning and dyeing processing and silk printing processing
Continuous ginning and dyeing is generally divided into practicing bleaching, dyeing, printing, finishing four, the main production workshop.
I. Basic equipment:
Bleaching and training equipment (pre-treatment): burnishing machine (gas burnishing machine, copper plate burnishing machine), cooking machine (flat, rope), oxygen bleaching machine, chlorine bleaching machine, mercerizing machine.
Dyeing equipment: hot melt dyeing machine, roll dyeing machine, infrared priming machine, color development soap washing machine.
Printing equipment: flat screen printing, round screen printing, roller printing, transfer printing, digital printing.
Whole set equipment: sizing machine, stenter, abrasion machine, calender, pre-shrinking machine, yard shear machine.
Second, the process:
1, the original cotton fabric inspection - turn the printing - sewing head - burnout - -(Desizing -)Boiling - Bleaching - Mercerizing - Drying)
Burning
Burnishing: The purpose of burnishing is to burn off the fluff on the fabric surface, so that the fabric surface is smooth and beautiful, and to prevent the presence of fluff in the dyeing and printing due to uneven dyeing and printing defects. Fabric burning is the fabric flat fast through the high-temperature flame, or rubbed through the red-hot metal surface, when the cloth surface on the presence of fluff quickly warmed up, and combustion, and the body of the cloth is more compact, the temperature rises slower, in the case of not rising to the point of ignition, that is, has left the flame or red-hot metal surface, so as to reach the burned off the fluff, and does not manipulate the fabric of the purpose.
Desizing: textile mills in order to smooth weaving, often on the warp yarn sizing to improve strength and abrasion resistance. Sizing on cotton fabrics can be desizing from the fabric using alkali desizing, enzyme desizing, acid desizing and oxidizer desizing.
Cooking: cotton fabrics after desizing, most of the pulp and some natural impurities have been removed, but there is still a small amount of pulp and most of the natural impurities remain on the fabric. Cooking is the use of caustic soda and other cooking aids and gums, waxy substances, nitrogen-containing substances, cottonseed hulls, chemical degradation reaction or emulsification, puffing effect, etc., after washing to make the impurities from the fabric to retire.
Bleaching: cotton fabrics after boiling, due to the presence of natural pigments on the fiber, its appearance is not white enough for dyeing or printing, which will affect the brightness of the color. The purpose of bleaching is to remove the pigment, endowed with the necessary and stable whiteness of the fabric, while the fiber itself is not subject to significant damage. Commonly used bleaching methods for cotton fabrics are sodium nitrite, hydrogen peroxide and sodium chlorite.
Mercerization: Mercerization refers to the cotton fabric at room temperature or low temperature, in the direction of the warp and weft are subjected to tension conditions, with a concentrated caustic soda solution to improve the fabric properties of the process. Cotton fabrics after mercerization, due to fiber expansion, fiber longitudinal natural twist disappears, the cross-section into an oval, the reverse of the light is more regular, thus enhancing the luster.
Dyeing: Dyeing is a physical or chemical combination of dyes and fibers, or chemical methods to generate pigments on the fibers, so that the entire textile with the necessary color process. Dyeing is carried out under the conditions of necessary temperature, time, ph value and required dyeing auxiliaries. Dyed products should be uniform color, but also need to have good dyeing fastness.
Finishing: cotton fabric finishing includes mechanical and chemical aspects. The former has stretched, rolling, electro-optical, rolling and mechanical pre-shrinkage finishing. The latter has a soft finishing, stiffening finishing, whitening finishing to the main shrink-proof finishing.
Thoughts and experiences
When I visited Shaoxing Zhiren Printing and Dyeing Factory, Hangzhou Huatai Silk Printing and Dyeing Company Limited, not only deepen the knowledge of the classroom, but also got a lot of classroom learning can not be. After learning the process of dyeing and finishing process, visited the factory of the whole process of dyeing and finishing, familiar with the basic process and dyeing and finishing equipment, the future study and work will certainly be a great help. The psychological feeling of pressure is very, from the days of looking for work is getting closer and closer, although the environment of those companies is not very good, but experience the working life, found that I have to learn a lot of things in the future, I will be more diligent in the future study, learn more knowledge, and then work hard to start their own new life journey!

I. Internship time
June 15, 2010 - July 3, 2010
Second, internship location
Jilin Machinery Brake Factory, Changchun Changjiu Logistics, Beijing Railway Logistics
Third, internship information
The internship mainly visited Jilin Machinery Brake Factory, Changchun Changjiu Logistics and Beijing Railway Logistics to understand the business of these enterprises, familiarize with the business flow, and have a preliminary understanding of these enterprises.
1, Jilin Machinery Brake Factory
The business process mainly includes plastic stamping, machining, surface treatment, and storage of goods.
First of all, under the leadership of the staff, we visited the plant's stamping sub-factory, the door of the plant is written on the "stamping excellent products, shaping a good image, recognize the situation, firm confidence." Entering the plant, we could only hear the roar of the workers who were working hard in such a noisy environment. The middle part of the plant is placed in two rows of punching machines, machinery far turn very quickly, the workers must always concentrate on stamping auto parts. On each press, there are 3-4 operation charts and precautions hanging in order to standardize the operation. The layout of the plant with material storage, mold storage, geometric measurement room, maintenance area, restricted area, table washing class, pending inspection area, these layouts prove the various processes required for the production of these auto parts.
Then we visited the machining sub-factory, whose production slogan is "Duty, Innovation, Truthfulness, Achievement". Entering the plant, the first thing you see is the publicity column, which has information on corporate culture, work precautions and other information. The first thing you will see is a publicity board with information about the company's culture and the importance of work. There is a processing area for parts of different brands of automobiles, and there are several processing lines.
Finally we visited the surface treatment branch. Visiting the internship report sample. Its staging area was large, but not neatly organized. Outside the plant, we saw a small open storage area with some box pallets.
This visit is mainly to have a general understanding of the logistics process of auto parts production.
2. Changchun Everlasting Logistics
The business process is mainly based on vehicle logistics planning, parts logistics, general cargo flow, warehousing, transportation, distribution, automobile sales and after-sales service.
First of all, Mr. Cai, the manager of Human Resources Department of the company, gave us an introduction of the company. During the introduction, we watched the image data of Changjiu Logistics. The company was established in 1992, headquartered in Beijing, and is an intensive and comprehensive service group company in the fields of vehicle logistics planning, parts and components logistics, general cargo flow, warehousing, transportation, distribution, automobile sales, and after-sales service, etc. The total number of employees is more than 2,000. The total number of employees reaches more than 2,000. Involved in passenger car logistics, commercial vehicle logistics, automobile sales, auto parts logistics and general cargo logistics, etc., the business areas throughout the country, with more than 50 wholly-owned, holding subsidiaries, more than 10 commercial vehicle warehousing bases, warehouses with a total area of more than 1.3 million square meters, with an annual potential of 600,000 units of transportation, automobile sales of more than 20,000 units. It is a modernized private automobile logistics enterprise in China, and ranks among the top three in China's automobile logistics industry. in September 2003, Changjiu Logistics was certified to ISO9001:2000 quality management system, and in January 2006, it was awarded as a 5a-level logistics enterprise by the China Federation of Logistics and Purchasing (CFLP), and became one of China's 15 enterprises with the 5a-level logistics standard.
Secondly, there are professionals in the transportation department to explain the company's automotive logistics shipping status. There are more than 2,300 transportation vehicles in Changchun Logistics, and more than 3,000 outsourced vehicles. In Changchun alone, there are more than 10 outsourced vehicle companies that have signed agreements with Changchun Logistics on transportation. This ensures that Changchun Logistics has an annual capacity of more than 1 million. In Changchun, Changguang Logistics mainly transports the commercial vehicles of FAW-Volkswagen, Malibu and Toyota. The shipping process is as follows: Firstly, the sales department feeds back the required number of commodities to the storage and transportation management section, which analyzes the data, calculates the required vehicles and arranges the transportation time, and then issues the transportation plan to Changchun Long Term Logistics or other outsourcing vehicle companies. Secondly, the transportation vehicle starts the preparation work. This includes the preparation of workers' work clothes, vehicle inspection, and loading. The outsourcing vehicle needs a "loading confirmation". Third, transportation out of the warehouse.
Then the teacher led us to visit the open-air warehouse of Changlong Logistics - the area for storing, warehousing and delivering goods vehicles. And the staff patiently and meticulously explained to us. The storage area is very big and the first impression is neat and orderly. Each commercial vehicle is put into storage by the guide driver, and in this process, the appearance and quality of the car is inspected. Each cargo space is documented. After storage, the cargo space numbering is carried out, and then copied into the fixed form by the storekeeper, and finally the data is entered into the computer. This ensures the accuracy of the stored data and facilitates a quick and accurate search for the required vehicles. When the company receives a sales order, it will be handed over to the warehouse department for allocation, and the required vehicles will be driven by the guide driver to the warehouse in a neat line. These vehicles will be placed in the merchandise trucks.
Finally, we watched the loading process of the specialized trucks for commercial vehicle transportation. There are several procedures to be done before its preparation, such as the installation of landing gear, this process can only be manually operated, very time-consuming, at least, it took nearly 30 minutes of time. Each commercial truck can carry 10 cars and is loaded on two levels. We saw two kinds of special vehicles for commercial vehicle transportation, box-type and frame-type. The staff told us that the loading capacity of the frame type is higher than that of the box type, and the frame type will be used more in transportation in the future.
3, Beijing Railway Logistics
The business process mainly consists of receiving, warehousing, delivery, distribution, logistics packaging, information management.
The enterprise was established in 2002, is a private enterprise, the main scope of business for the express delivery of auto parts, in Beijing and Shanghai have warehouses. Its market share in Jilin Province accounts for 30% - 45%.
Walking into the Beijing Railway Logistics, there does not give a busy scene.
First of all, the company's manager Lou led us to visit the company's warehouse. There is a lot of storage space, but not clean, the stacking of goods is not neat, only two or three forklifts in the transportation of goods. Some of the goods on the sale of a thick layer of dust. There is no neat and tall shelves. Floor manager told us that today many logistics enterprises are such a status quo, is due to the limitations of capital costs, no financial resources into the shelves and forklifts, and for the current volume of goods transportation of the enterprise is not necessary to do so.
I saw some of the cargo space is still hanging a lot of cargo space does not fit the cargo layout board. Most of the goods were on the floor, no shelves were used, and there were only a few wooden and iron pallets. There are not many goods there, the date of shipment are the same day to be shipped, there is no yesterday or earlier time of the goods, it can be seen that the Beijing Railway Logistics shipments in a timely manner. I saw the electronic scales for weighing cargoes embedded in the floor, which are flat and can facilitate the weighing of cargoes on and off the scales. Freight center in the warehouse next to the entrance, is the place where the cargo information is understood, entered and issued.
The last by is the founder of the company Shao general manager for us to explain. The **** knowledge was initially from 2 cars, 6, 7 people sent to today's scale of such a comparative fight. His story makes me feel the hard and difficult to start a business, his words are still fresh in my mind "to put it nicely is a history of entrepreneurship, in fact, it is a history of blood and tears. As well as the difficulties of doing logistics planning for other enterprises, they are all accumulated and summarized little by little in the grassroots practice.
General Manager Shao also explained to us that the warehouse for the withdrawal of the cargo layout board is due to the original use of corporate services to the company withdrew the goods, but at the moment to re-request services, so those cargo layout boards continue to be used.
Fourth, the internship experience
After a week of visiting the internship, we have gained a lot. Let me understand the Jilin Machinery Brake Factory, Changchun City, long-lasting logistics company, Beijing Railway Logistics Company's mode of operation and related business, so that I have a more in-depth understanding of the various functions of logistics and awareness. When I got out of the campus, I really realized the complexity and hardship of social work. In the lectures those staff speak of logistics terminology and management cases often make me feel the mind of the professional knowledge fuzzy and lack of professional knowledge, this time to y appreciate their own knowledge is so little. No practical experience and skills, the theory and knowledge of the books and the reality of a large gap, we should clearly recognize that the logistics industry is a new industry, with a lot of space for development and market potential, employment prospects are very promising. However, it is a kind of hard industry, the social demand for more is the actual operation of personnel, and management, logistics engineering design talents need less, but it is very lack of, however, the growth of these high level of talent also need to work out from the grass-roots level in the actual operation of the exercise, feel, otherwise it is not a good combination of the professional theory of logistics and the actual. Therefore, in order to fight for the future of the logistics industry, to become a high-level talent in logistics management, during the university period we should have a solid professional knowledge, but also should cultivate hard-working, solidarity and cooperation spirit, correct their own mentality, down-to-earth and conscientious, which is very helpful to us in the future employment, career choice.
The visit to the internship, the Beijing Railway Logistics General Manager Shao always with a humble attitude for us to explain, although not logistics graduates, but a little bit of down-to-earth in the logistics industry, this humble and down-to-earth attitude is very worthy of our learning. Its entrepreneurial spirit and entrepreneurial history is very inspiring to me.
