[0027] Among them, the positioning column 28 can be raised and lowered, so that all processing positions of the product can be exposed for processing, which makes it convenient for the equipment to process the product into shape in one time and improves the processing efficiency.

[0028] The present application provides a battery cover positioning fixture, including a base plate 10, a positioning seat 20, and a cover plate 30, wherein the positioning seat 20 is arranged on the base plate 10; the positioning seat 20 is provided with an electromagnet 13 and a vacuum suction hole 25; the vacuum suction hole is connected to the airway on the positioning seat 20; the cover plate 30 can be covered on the positioning seat 20 and can be adsorbed by the electromagnet 13; and a plurality of lifting and lowering positioning columns 28 are arranged around the positioning seat 20. The cover plate 30 is preferably made of stainless steel or steel plate, or other metal plates that can be magnetically attracted. The positioning seat 20 is fixed to the base plate 10 by screws or pins. The vacuum suction hole 25 is connected to a plurality of airways, and the vacuum suction hole 25 and the airway can adsorb the product to be processed, thus ensuring the firmness of the product. At the same time, the electromagnet 13 adsorbs the cover plate 30, and the cover plate 30 also adsorbs the product to be processed, so that the product to be processed is doubly fixed, which can well ensure that the product does not loosen during processing. Preferred loading steps: 1. The positioning column 28 is raised, and the punched battery cover is placed into the adsorption area. The positioning column 28 confines the product to be processed in the adsorption area. 2. The vacuum pump is connected to the vacuum suction hole 25 through a pipeline, and multiple vacuum suction holes 25 and the airway simultaneously suck the product. 3. The cover plate 30 is closed on the positioning seat 20, and the electromagnet 13 is turned on.
