Electric Drive Controller Assembly Line

　　The electrical control line features a flexible design and leverages RFID for data transmission and information binding. As one of the core components of new‑energy vehicle “three electric” systems, data collection and quality management during assembly are key considerations throughout the entire production line. The assembly line encompasses critical processes such as tightening, press‑fitting, welding, adhesive application, and conformal coating, all of which can be automated to ensure quality control and traceability, thereby effectively maintaining high assembly pass rates. In addition, the line employs interchangeable tooling and fixtures to accommodate different product variants.

　　Product Overview: Enclosure assembly line, IGBT module assembly line, main production line, test line, and more.

　　Applicable field: New energy electric drive controllers.

　　Main process:

　　Cover plate adhesive application and curing: Apply adhesive for sealing prior to assembly, then cure it in an infrared curing oven.

　　Wave soldering: IGBT board soldering, with pallet‑based automated flow‑through soldering.

　　Apply three‑protective coating: Apply paint to the IGBT board after soldering.

　　AOI Inspection: Inspects soldering quality to prevent missing焊s and false焊s.

　　Overall Leak Test: Controller Overall Leak Test

　　Bolt tightening: can be categorized into automatic tightening and manual tightening.

　　Automatic Line Transfer: Automated line transfer between the assembly line and the testing line using robots.

　　EOL Testing: controller firmware flashing, battery charge–discharge testing, battery safety compliance testing, battery parameter testing, BMS testing, auxiliary function testing, and more.
