The automobile oil pump motor assembly line consists of 19 equipment, and the conveying method adopts a conveyor line+ship plate, with a circular layout. Fully utilize process methods such as data tracing, visual inspection, depth detection, upward material identification, mixed material identification, missed assembly identification, material assembly front and back identification, pressure monitoring, displacement monitoring, etc. to achieve a foolproof and error proof effect. The production line mainly consists of automatic assembly of upper and lower insulation covers, clamp welding, magnetic steel assembly into the iron core, rotor, end cover assembly, signal magnetic steel assembly, locking screws, testing of motor back electromotive force, current, speed, and other assembly processes.
