Suggestions on painting of automobile production line. Urgent. . . . . .

In order to complete the car for the National Games as scheduled, the painting workshop has determined four "essentials" according to the actual production: one is to ensure the safety of equipment and personnel, the other is to ensure the quality of details, the third is to ensure the overall progress, and the fourth is to try to reduce costs and increase efficiency. The equipment is ready for safe use. The height of the rail car is 3.7 meters, so it is easy to have safety problems when passing through the spray drying room. The workshop re-measured all spraying rooms, drying rooms, grinding rooms and lifting platforms, and contacted the equipment department for rectification, which was basically completed before the order was transferred to the workshop without affecting the progress. The maintenance class in the workshop will also investigate the equipment prone to problems and replace and repair some parts to ensure foolproof. Technical preparation ensures quality. The technical inspection team in the painting workshop gave full play to the advantages of joint operation, made technical disclosure to the technical inspectors in Bofa workshop, and confirmed the vehicle status with the technicians in the welding workshop in the previous process in time, and summarized the problems and gave feedback. The key points of quality control are formulated, including personnel construction, control of squad leader and inspection technician, and confirmation of technical team leader and inspection team leader. Dig deep into potential and accumulate energy. In the tight production task, the painting workshop pays attention to the popularization and application of workers' rational suggestions on energy saving and production improvement, and has achieved good results. For example, Li proposed that "white paint and green paint should be sprayed at the same time" to reduce the baking and protection of one color paint; "Two kinds of lining paints are sprayed at the same time" put forward by Lu Weidong, which can be protected once and dried to make up the virtual paint. Yuan's "narrow plate shielding spraying lining coating" also realizes one-time spraying of two lining coatings. The "simultaneous scraping and coating of inner cavity wax and putty" proposed by the technical team reduces the sealing time by more than 20 minutes; Fang's "rear bumper operation" ensures the color consistency of the rear bumper to a certain extent. A series of optimization improved the production efficiency by nearly 10%, compressed three beats, and saved energy and auxiliary materials costs, 350 yuan. The main task of production management painting workshop is to produce high-quality painted car bodies, so it is necessary to strengthen control in the following aspects: 1. Strictly require production line operators to carry out standardized operations according to the work instructions in the system documents, so as to reduce the randomness of employees' operations, ensure product quality, and create a good working environment for employees while ensuring quality; The operation mode of workers is the key to the quality of finished products, and the mood of employees is also directly related to their work results. Implement internal customer system. For the unqualified organism, the next working procedure has the right to refuse to continue production, and the personnel in the previous working procedure are assessed accordingly to improve the quality awareness of employees. 2. Rational allocation of workshop personnel. Only by reasonably assigning tasks to corresponding employees can tasks be successfully completed. In order to make reasonable arrangements for employees, team leaders and section chiefs who know the skills of employees should be assigned fairly, and employees with higher skills should be assigned to key positions or accident-prone points to avoid quality problems flowing into the next process due to new employees or employees with lower skills. Team leaders and section chiefs should also learn to check the work and track and confirm the work of employees while reasonably arranging each employee. 3. In terms of the start and stop of production line equipment, according to the process requirements of each station in the workshop and the performance parameters of the equipment, the start and stop of each production line in the workshop are reasonably optimized, so as to save kinetic energy and maximize production efficiency. For example, the cold heating time (from production to commissioning) of electrophoresis drying furnace is generally 1.5 ~ 2 hours, so it must be heated in advance to ensure that the process parameters of each station can be met during production. Other things that need to be heated in advance mainly include degreasing tank and pre-degreasing tank, and the ventilation and air conditioning of spray booth should also be treated accordingly. 4. Energy conservation and environmental protection have become common problems faced by enterprises today. Doing well in this respect will help to enhance your core competitiveness. Grouping production models and colors can, on the one hand, improve the production efficiency, increase the output per unit production time by reducing the pitch, and reduce the labor of painting workers; On the other hand, it can reduce the solvent consumption and reduce the treatment cost of waste paint and waste solvent caused by frequent color changing and cleaning. Employees are required to turn off the water, electricity and gas sources in time when the production line stops, and inform relevant personnel to turn off the air conditioning and air supply in time to avoid wasting kinetic energy. facility management

Figure Equipment maintenance system With the development of science and technology, equipment is becoming more and more intelligent and integrated, and the production of workshop is increasingly dependent on equipment production. The quality of the produced car body is closely related to the equipment. Therefore, how to maintain, repair and manage the equipment is an important work in the workshop. Equipment management mainly focuses on the following aspects: 1. There must be a perfect equipment management system, and there are many popular equipment management systems at present. Therefore, the workshop must judge according to its own situation, learn from the strengths of many experts, and formulate a set of practical and efficient equipment management system suitable for the workshop. According to the requirements of equipment management system, make a perfect daily maintenance, overhaul and repair plan. According to the operation status of the equipment, the equipment shall be repaired, maintained and lubricated accordingly, and the inspection shall be strengthened to ensure that the equipment maintenance is in place. After maintenance, the equipment after maintenance must be checked for trial operation to ensure the normal operation of the equipment in the production process and reduce the downtime of the equipment. 2. Before the equipment starts to work, it is very necessary to carry out spot inspection and patrol inspection in the normal production process. Spot check is to ensure the normal production of equipment, solve and track the problems found in time; Generally, there are corresponding signs or abnormal phenomena before the equipment fails, so the equipment failure can be solved in the early stage to ensure that it will not cause major failures and equipment downtime, so it is very important to strengthen the inspection work. At the same time, it is also one of the development directions of equipment maintenance in the future to detect the running state of equipment through effective measuring tools and realize preventive maintenance of equipment. In addition, strengthening equipment lubrication is also a simple, reliable and effective method to avoid major equipment failures. 3. Implement the equipment responsible person system, and the equipment maintenance personnel shall have corresponding responsible equipment, and conduct dynamic assessment according to the equipment downtime. The person in charge of equipment should prepare corresponding materials for typical equipment failures, that is, the causes of equipment failures, the solution process, how to avoid recurrence, and what measures and methods to take if it happens again. Hold an analysis meeting attended by all equipment personnel to promote the improvement of maintenance personnel's skills. The person in charge shall formulate the corresponding equipment emergency plan to minimize the loss caused by equipment downtime. 4. Management of spare parts, wearing parts and grease. According to the needs of equipment running state, dynamic management is carried out to ensure that the equipment meets the needs. Special attention should be paid to some special spare parts, especially the spare parts of imported equipment, because their supply cycle is generally long. Minimum inventory should be set for some key equipment and equipment prone to problems, and the inventory should be replenished automatically. Strengthen spare parts maintenance and waste utilization management, and save workshop equipment maintenance costs. The process management of the process management workshop shall be carried out in strict accordance with the requirements of the management system: 1. Appropriate process parameters are the premise of normal production in the workshop, so it is necessary to strictly control the process parameters in the workshop, that is, register the personnel, time, specific values and reasons of parameter changes, and track and confirm the changed parameters. According to the requirements of relevant system documents, a set of practical program documents is compiled in combination with the actual situation of the workshop, and it is strictly required for the workshop process and production personnel to implement. 2. During the workshop production, the paint body review meeting will be held on site every day to analyze and discuss all quality problems, implement the quality problem traceability system, arrange all workshop staff to take turns as far as possible, strengthen the publicity of quality management knowledge and improve the quality awareness of all staff. 3. Pay attention to the development and application of new technologies, new processes and new materials. The competition in cost and quality of automobile manufacturing enterprises is becoming more and more fierce, so more and more automobile factories adopt more environmentally friendly, energy-saving and high-quality painting processes, production lines and equipment. The workshop can be combined with the development of the company and the current situation of the workshop, and the existing equipment can be modified or improved accordingly, such as using water-based coatings to greatly reduce environmental pollution, especially VOC emissions; Using natural gas tar waste gas to burn the drying furnace not only greatly reduces the kinetic energy cost, but also reduces the environmental pollution. Monitor the generation and treatment of "three wastes" such as waste water, waste gas and waste generated in the workshop to ensure that the treatment conforms to relevant national policies and regulations. 4. Actively optimize various process parameters to reduce workshop kinetic energy, production and auxiliary materials costs as much as possible. By optimizing the long and short cleaning procedures of the robot, not only the consumption of solvents can be reduced, but also the cost of treating these waste paint solvents can be reduced. 5. The first-in-first-out system of various production and auxiliary materials used in the workshop can ensure that they are applied to the production site in time. At the same time, the main suppliers of production materials are required to implement the following production service system to ensure a rapid response mechanism to solve problems. Safety and health management Safety in production is the premise of every company's production and the basic requirement of the state for enterprises: 1. We should not only pay attention to safety in the production process, but also pay special attention to equipment maintenance. On the one hand, the personal safety of employees, at least 1 people are accompanied or cared for when working or climbing in dangerous areas; On the other hand, it is the safety of equipment and workshop, especially the fire prevention and theft prevention work in the workshop. When hot work is carried out in the workshop, it should be supervised and monitored in strict accordance with the company's system to ensure that there is no fire. A company once had employees smoking on the third floor of the workshop, which is the air conditioning platform. During the commissioning and production of the new workshop, the grounding wire of the high-voltage electrostatic spraying robot was stolen, but fortunately it was found during the inspection. In order to prevent further equipment failure, the workshop stopped production for 2 days. Although the value of grounding wire is not great, the loss brought to the company by stopping production for 2 days is huge. 2. As we all know, the requirements for sanitation in the painting workshop are very strict and demanding, so most workshops contract the cleaning of the workshop to professional cleaning companies as a whole. When signing an agreement with the cleaning company, it is necessary to list all the work that the workshop needs to do, and make certain requirements for its personnel composition to avoid affecting the cleaning work in the later period. Technicians should dynamically manage all kinds of filter materials in the workshop to ensure that the requirements of process parameters are met. When the cleaning company replaces air conditioners, drying furnace filter materials and other work closely related to process parameters, it is necessary to send people to follow up and check. Prevention of occupational diseases is also a must in the workshop. According to different positions, the workshop can conduct regular inspections and physical examinations for the workshop employees, discover and understand the physical condition of the employees in time, and take corresponding solutions in time according to the mastered situation. When employees are found to have signs of occupational diseases, they should be informed in time to deal with them themselves and be transferred from their posts. At the same time, investigate the original post, and if it is caused by the station, the station should make rectification. In addition to the above management, there are many aspects of workshop management that need attention: 1. Cost management. In the fierce market competition, the better an enterprise does in this respect, the stronger its core competitiveness. Therefore, while doing a good job in the workshop, we should strictly control the kinetic energy, labor, tools, maintenance costs, production materials and auxiliary materials consumption of the workshop. 2. Workshop site management and 5S management. This general management method is also suitable for painting workshop and is an effective management method to improve work efficiency and quality. Through the visualization of information, more information such as production, cost and equipment can be conveyed to employees in the workshop, and the cohesion of employees in the workshop can be improved. 3. Hold CC and QC meetings regularly to improve the enthusiasm and initiative of employees, give full play to their intelligence, improve the working environment of operators and improve workers' satisfaction. 4. Strengthen publicity work. Because the employees of the production line only operate on the production line, they know little about the company's information and news. Therefore, timely posting information and news that can motivate employees to the site can encourage Qi Xin to work together to do all the work in the workshop. The methods that can be adopted include: holding employee seminars regularly to understand employees' voices and needs, responding and rectifying employees' problems in time, and improving employees' satisfaction. 5. Carry out the collection of prize-winning rationalization suggestions, and set up a special person to be responsible for this matter, and give certain rewards to suggestions that can bring certain economic and safety improvements to the workshop and the company, so as to encourage more employees to actively participate. 6. Implement a strict dynamic reward and punishment system. Closely combine employee income with employee skills, labor volume and labor intensity, and form a competitive atmosphere of being proactive and catching up with each other in the workshop. Of course, this is a systematic project and cannot be completed in a short time. 7. Conduct skills competition. By holding skills and standardized operation competitions, we can promote the enthusiasm and initiative of work, stimulate employees to learn from each other and improve their operation skills, thus improving work efficiency and product quality.
