Assembly line refers to a continuous production line connected by some material handling equipment. Assembly line is a very important technology. It can be said that any final product with a variety of parts and components and mass production is produced by assembly line to some extent. Therefore, the layout of the assembly line is affected by many factors such as assembly line equipment, products, personnel, logistics, transportation and production mode. The assembly line layout should be careful, otherwise, the well-designed products, expensive equipment and good sales will all end up in poor assembly line layout. At the same time, assembly line layout should be combined with modern management, and how to manage should be considered. Some advanced management methods are directly related to assembly line layout.
Pay attention to the following points when arranging the assembly line:
1. The selection of equipment for equipment assembly line is determined according to product technical requirements and assembly process methods.
Correct selection of process equipment and tooling for assembly line layout can not only improve production efficiency and reduce manufacturing costs, but also rationalize the assembly line layout process. The problems to be considered when selecting assembly line equipment include: product production program, product quality requirements; Progressiveness of equipment; Equipment reliability; The price of the equipment.
2. Product structure and assembly process design are the primary considerations in assembly line layout.
Analyzing and studying the product structure and putting forward suggestions for improving the product structure can greatly simplify the production process of the assembly line.
3. Production mode Production mode is an aspect that needs to be considered when arranging the assembly line. To determine the production mode, the following points need to be clarified: production program, work system, which refers to the working shift and working time of each shift, production line type, whether to adopt automatic line or assembly line production, whether to produce alone or in groups, management mode, which refers to the management methods, systems and regulations required to ensure production.
4. The assembly line logistics and transportation material flow are completed through transportation. Material transportation is essential in the factory. We should choose an economic and reasonable transportation mode. It can be concluded that the amount of material movement depends on its production factors. The assembly line layout must ensure the shortest transportation distance of the material flow, and always flow to the end of the product assembly line, and establish a control system to ensure the material flow.
5. Warehousing and auxiliary facilities.
The material flow always flows to the end of the assembly process, but whenever the material is interrupted, the production will be stopped for materials. Therefore, it is necessary to retain a certain amount of reserves to ensure the flow of material flow on the assembly line, which is economic and reasonable in maintaining production and balancing process capacity. In addition, auxiliary equipment plays an important role in providing maintenance and service for production.
6. Once the plant structure is established, its variability is relatively small, so it should be carefully considered in the design, and the plant structure should be determined according to the production characteristics. If there are special requirements on the assembly process, the workshop needs to be specially designed. Generally, the general plant shall be used, and the multi-storey plant shall be comprehensively considered according to the process characteristics of the assembly line layout and the land occupation.
7. The flexibility of assembly line layout.
