[0002] The white body needs to be welded in the white body manufacturing process, and the splash produced in the spot welding process often forms a pimple, burr, and even leaves welding slag in the white body, which usually adheres to the door frame and other key parts, and if not removed in time, it will not only affect the appearance quality of the white body, but also affect the subsequent manufacturing process, such as coating electrophoresis failure, electrophoresis pool accumulation of welding slag particles, and total assembly installation of adhesive tape leading to cutting, and even causing other safety problems in detection operation.
