BACKGROUND

[0002] To meet the personalized customer demand, improve production efficiency, reduce production cost and guarantee product quality has become the key to enhance the market competitiveness of automobile enterprises, and advanced production modes such as flexible manufacturing, agile manufacturing and intelligent manufacturing are gradually applied. A variety of vehicle models can be produced on an assembly line to meet the individualized and diversified needs of customers.

[0003] With the continuous increase of vehicle models, the limited line-side area puts forward higher requirements for reasonable and efficient logistics layout design. The traditional line-side logistics layout design method mainly uses EXCEL calculation, CAD drawing and physical wiring verification by manual work. When the parts change, it is necessary to recalculate, arrange and verify, which consumes a large amount of repeated manual work and time cost in logistics planning.

[0004] The existing automobile factory workshop line-side logistics layout design method mainly uses manual calculation and CAD layout drawing, and the physical wiring verification and adjustment are as follows:

[0005] (1) Obtain the part list and corresponding station information, and match the line-side logistics area one by one;

[0006] (2) Confirm the logistics mode of each part one by one: order drawing, large part order building, large part SPS, large part batch, small part order building, small part SPS, small part batch;

[0007] (3) Confirm the line-side storage appliance information corresponding to each part: storage number, appliance size;

[0008] (4) According to the process requirements such as mechanical hand grabbing range and line-side equipment occupation, calculate whether the line-side storage area of each station meets the actual layout space, output the part-level CAD layout diagram of the station if it meets the requirement, and adjust the logistics mode and corresponding line-side storage appliance if it does not meet the requirement, and recalculate;

[0009] (5) According to the output CAD layout diagram, the physical field is placed and verified and adjusted to confirm;

[0010] The existing technology has the following disadvantages:

[0011] (1) The existing line-side logistics layout has a large amount of repetitive work such as manual confirmation of line-side storage layout for each part, recalculation, drawing and line-side physical wiring verification for each adjustment of logistics mode, and a large amount of manpower is required for adjustment.

[0012] (2) For production line, process layout adjustment or part change, real-time information cannot be obtained and timely response, and the corresponding change needs to re-arrange the overall layout, the response is slow;

[0013] (3) The layout change corresponding to the logistics mode adjustment is not intuitive, and needs to be matched and verified on site, the verification period is long, and the design implementation effect is poor.

[0014] Through the analysis of the existing line logistics layout pain points, the automatic line logistics layout platform is established, and the linkage of production line, process layout and line logistics layout is realized, which is important for improving the efficiency of line logistics layout.

The production line and process layout information can be synchronized in real time, the line logistics area can be automatically adjusted, and the logistics mode and the corresponding line storage device can be automatically matched and adjusted. The present application can quickly output multiple alternative schemes, analyze the line logistics layout corresponding to different logistics modes, and automatically output the part-level line logistics layout diagram meeting the planning requirements, thereby avoiding inefficient and low-value repeated calculation and drawing.
