Independent analysis of SE, independent planning of the whole line

As one of the four major processes in the automotive industry, the welding process is self-evident. It shoulders the important mission of forming the body and providing a supporting frame for the vehicle. In addition to ensuring the appearance and shape, it must also ensure that all parts of the final assembly The precision of the component installation point, so its process is far more complicated than the other three major processes. The planning and layout of the production line not only need to consider from the aspects of precision assurance, production efficiency, distribution logistics, and storage, but are also limited by the plant area and structure, Existing conditions such as painting corridors. There is no perfect layout plan, only the most suitable layout plan at present.

Splitting the process and determining the number of stations

The design department enters the overall product structure, drawings, and process routes, defines the content of the welding process, and then splits the process into a single station. The following principles must be followed:

(1) Spot welding is generally calculated according to the average operation time of each welding spot of 3s;

(2) Due to the low dust emission and low work efficiency of arc welding, it is necessary to arrange it as concentrated as possible to avoid dispersion;

(3) The operating time of loading, picking up, clamping and opening of fixtures can be set according to past experience;

(4) The effective working time + delivery time of a single station shall not be greater than the working time of the station;

(5) The station loss in the conveying arrangement needs to be considered.

Delivery method of side panel assembly

Most of the side wall assembly belongs to the A-level appearance surface, which requires high surface quality. Therefore, its conveying method needs to consider the conveying efficiency, whether it needs inventory, the layout area of the side wall line and other factors. It can be divided into single-side wall conveying and There are two kinds of supporting conveying for both sides.

(1) Single side wall conveying

Advantages: low cost, integrated gripper and conveying, no need to set up spreader and gripper separately;

Disadvantages: 1: Only one assembly can be returned to transport the next assembly after the work is completed, and the beat is low; 2: There is no buffer inventory, when the side line is abnormal, it will directly affect the shutdown of the entire production line, and there is no room for buffering ; 3: After the side wall is transported, it needs to be used with the turning fixture.

Scope of application: Applicable to welding lines with a relatively low tempo, and the side lines must be arranged on both sides of the main line, and the assembly station must be used with the flip fixture.

(2) Supporting conveying on both sides

Advantages: high conveying efficiency, flexible formulation of buffer inventory, and not limited by conveying distance, flexible selection of assembly station fixtures.

Disadvantages: It needs to be used with automatic grippers or grabbing robots, and the cost is high.

Scope of application: suitable for high-tact production lines, when the workshop area is large and the side line is far away from the main line.
