Automated production line production efficiency mainly refers to the automated production line in the unit time required to produce semi-finished products, which is to evaluate whether an automated production line is qualified as one of the important indicators, in the automated production line design process needs to be carried out on the various stations beat analysis and integration of the small beat workstation on the automated production line in the bottleneck to be eliminated to reduce the automated production line design of redundant process links, improve production Redundancy in the design of the automated production line to reduce the redundant process links, improve production efficiency.
The production beat in the automated production line is mainly composed of process operation time and auxiliary operation time, in the automated production line of the production beat design to first of all on the production line of the balance of the rate of certain design calculations. In the completion of the production line balance rate calculation on the basis of the production line beat calculation, this is due to the automation of the production line of the longest beat of the workstation will be more serious restrictions on the operation of the other workstations, therefore, the production of automated production lines in the production beat is mainly by the automated production line operation process of the longest running time of the workstation beat is determined. In the design of the automated production line needs to analyze the longest workstation to determine whether it can shorten its running time to effectively reduce the beat bottleneck, so that the automated production line of the workstation running beat to maintain a certain balance.
3 to determine the design of the automated production line
In the completion of the design of the automated production line for the preliminary preparatory work needs to be automated production line design program to determine the automated production line design program in the process of determining the automated production line needs to automated production line for a number of program design and in the above program to select the optimal design. Optimal design program. Evaluation criteria for the optimal automated production line design: simplicity and practicality, reliability, and as far as possible to `reduce the manual operation, and in order to meet all the prerequisites of the function of the automated production line production costs, production efficiency and other aspects to determine. In the completion of the automated production line design program to determine the need for automated production line for three-dimensional model design, and draw the relevant two-dimensional engineering drawings.
3.1 Automated production line drive system and structure design
Automated production line for the traditional system and structure design needs to be based on the structure of the product to determine the form. Now in the automated production line in the use of more conveying methods are: chain transmission, belt transmission, as well as turntable conveyor and vibrating plate feeding, etc., and then the need for automatic generation of products in the product segregation and ring direction to consider, such as the need for parts detection or positioning in the workstation needs to be separated from the product and out of the transmission for accurate positioning. This ensures that the product is assembled, processed and inspected without the involvement of other external forces. In the automated production line for the conversion of the product to the main X / Y / Z three degrees of freedom composed of, in the direction of change can be carried out through the use of reversing cylinders, indexing discs or cam indexing and specific mechanical equipment to realize the automated production line production process of the rotary function, in the automated production line in the process of segregation due to the differences in the beat of the various workstations will be there is a certain waiting phenomenon, such as the waiting time is a little long, it is necessary to wait for a certain period of time, so that the product is separated and detached from transmission. This waiting time is a little long, then you need to design the automatic production line in the temporary storage of material stacks.
3.2 Do a good job in the automated production line pneumatic schematic drawing
In the automated production line on the basis of the analysis of the product process needs to be lifting, clamping, linear motion, rotation and other functions to determine the realization of the design process needs to rely on the operation of workstations to automated production line pneumatic system schematic drawing to determine and draw.
