The automatic production line is a production system which is composed of the workpiece transmission system and the control system. It connects a group of automatic machine tools and auxiliary equipment according to the technological sequence, and automatically completes all or part of the manufacturing process of the product.
Maintenance
Repair
Automatic production line saves a lot of time and cost. In the cities with developed industry, the maintenance of automatic production line has become a hot spot. The maintenance of automatic production line is mainly completed by operators and maintenance workers.
There are two ways to maintain an automatic production line:
Synchronous repair method: during production, if any fault is found, try not to repair it, and adopt maintenance method. Make the production line continue to produce until the holidays, centralize the maintenance workers and operators to repair all problems at the same time. The equipment will be in full production on Monday.
Partial repair method: if there are major problems in the automatic production line, the repair time will be longer. Synchronous repair cannot be used. At this time, the use of holidays, centralized maintenance workers, operators, a part of the repair. Wait until the next holiday to repair the other part. Ensure that the automatic production line does not stop production during working hours. In addition, try to adopt the method of pre repair in the management. Install a timer in the equipment, record the working time of the equipment, use the wear rule to predict the wear of vulnerable parts, and replace the vulnerable parts in advance, so as to eliminate the fault in advance. Ensure that the production line is fully loaded.
maintain
Maintenance of automatic production line:
Check and clean electric circuit, gas circuit, oil circuit and mechanical transmission parts (such as guide rail) before and after shift;
Patrol inspection shall be carried out during the work process, spot check shall be carried out for key parts, and records shall be made in case of any abnormality. Small problems shall be handled before and after the shift (the time is not long), and major problems shall be prepared for accessories;
Unify the whole line shutdown maintenance, make a good plan for vulnerable parts, and replace vulnerable parts in advance to prevent trouble.
Prospects for development
The development of digital control machine tools, industrial robots and electronic computers, as well as the application of group technology, will make the automatic line more flexible and realize the automation of multi variety, small and medium batch production. The multi variety adjustable automatic line reduces the economic batch of automatic line production, so it is more and more widely used in the mechanical manufacturing industry, and develops to a more highly automated flexible manufacturing system.
