Industrial robots are really hot now, replacing the manual assembly line. The production line with hundreds of people now only needs seven or eight robot maintenance and debugging engineers, while welding, grinding and polishing, palletizing, sorting, carving and spraying are all widely used by industrial robots. In Huibang Robot, ABB, An Chuan, Fanuc and KUKA robot workstations are readily available, and polishing robots can also be seen everywhere. Therefore, we have learned a lot from the field trip, but it has not yet formed.
