Automotive/car door welding and assembling line

Industry:  Automotive

Technical capability:

Welding application
Robotic integration
Heating application
Vision application


Our customer request the line which has need to include: dispense process, welding process, punching process, heating process and pressing process, should fit with three different size of door.


The line was built on 6 stand alone station which included: welding station, punching station, heating station, pressing station, inspection station. Welding station was integrate with Motorman robot and high frequency welding system to finish the car door edge welding process. Then the punching station integrate with Keyence vision system to ensure the position accuracy. The heating station would maintain the temperature in certain degree to make sure the heating process. Then the pressing station with our own design pressing mold and hydraulic pressure system to ensure the pressure on the door.

Final step, is for inspection system,which integrate with Keyence vision system and senor to do the appearance check, and each station has RIDF card to upload the production data on the cloud for real time monitor.

Our customer request this line need to fit with three different size of door, for that, we analyze all the product feature, can custom the quick change system for all station, includes mechanical structure and programming. We designed three different product mold for each station, and easy to change the work mode( within 5min for each station).

Results and benefits:

This system helps custom massive improve productivity and quality rate.

And also can flexible fit with future product design by designing other mold and additional mechanical structure for upgrading.

Perfectly reach customer’s needs on ROI, high output rate and quality rate.
