In the first step, the cathodic dip-coated battery covers are provided via in-house boxes. The sheets are then centered using gravity centering for subsequent laser stripping.
A robot guides the part in front of a laser station with a scanner. The cathodic dip coating is stripped at four defined locations to create contact points for grounding the battery covers in the vehicle.
The two identical foam cells are loaded by a robot on a linear axis. Each foam cell consists of a turning device and two robots that simultaneously apply the 1K PUR sealing bead to the part.
After the foam application, each part is assigned an individual part number, which is applied to the part using a label printer. This allows for a subsequent tracking of the part, including all relevant production data.
The foam bead hardens in an oven with 12 drawers. developed by ROBOT-TECHNOLOGY. This oven also serves as a buffer and operates according to the FIFO principle, forming the interface between the raw and finished parts area.
To ensure the highest quality, each foam bead is precisely measured by a 3D laser measuring system. Regular random leak tests are also carried out in a vacuum station. If any abnormalities are found, the part can be inspected by an employee at a QA station.
After quality control, a robot sorts the finished parts into the customer-specific racks. After that, the lids of the filled boxes are automatically closed.
