According to the industry demand and market trend outlook, combined with the company's accumulation of intelligent manufacturing technology in the low-voltage electrical industry and an in-depth analysis of the product manufacturing process, ACA launched the high-voltage DC contactor intelligent flexible production line; this program realizes the whole process automation of the product from the assembly, dust removal, polishing, cold welding, laser welding, filling and exhausting, helium leakage testing, dispensing, functional testing, etc., effectively solving the DC contactor previous production process of manual assembly and testing, welding, filling and exhausting, helium leakage pick-up and other links offline, product manufacturing and testing formula can not be tracked and traced and other pain points. This effectively solves the pain points of the previous production process of DC contactors, such as manual assembly and testing, welding, filling and exhausting, helium leakage pickup, etc. offline, product manufacturing and testing formulas are set by human beings, and the manufacturing data cannot be traced and traced. The application of robots, flexible feeding system, vision, laser ranging, two-dimensional code and other new assembly and testing means, to achieve a high degree of flexibility and intelligence of the production line, different product models quickly change the production; one object, one code, to achieve real-time tracking and storage of the product assembly and testing data, traceable.
