The electrophoresis line process is:

Pre-cleaning → online → degreasing → water washing → rust removal → water washing → neutralization → water washing → phosphating → water washing → passivation → electrophoretic coating → tank cleaning → ultrafiltration water washing → drying → offline.

Passability analysis of coating equipment

The equipment passability analysis mainly includes the transport vehicle passability, chamber passability and robot capability analysis.

Coating and conveying vehicles mainly include pre-treatment electrophoresis skid (or trolley), double swing rod (or C-type spreader, etc.), side overhead machine (or transfer spreader), UBC holding gear, and paint skid ( Or trolley), craft trolley, etc.

When dealing with electrophoresis or topcoat skids and craft carts before analysis, we mainly focus on the position, height difference, size, support method and locking method of the front and rear support points of the skid on the production line. After the 3D data of the skid is implanted into the 3D digital model of the car body, it is easy to determine the position of the car body support point that conforms to the existing skid. Then, it is necessary to analyze whether the strength of the car body after being supported there, interference with the surroundings, stability, and the distance from the front and rear ends of the car body to meet the requirements. If it is not applicable, priority is given to adapting to the existing skids by optimizing the body support point settings. If it is not feasible to change the body structure, consider modifying the existing skid structure. When modifying the existing skid, try to consider the versatility, such as the locking method, the height difference of the front and rear pivots, etc.
