[0002] A battery refers to a cup, trough or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as an energy source can obtain a current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the battery has a simple structure, is easy to carry, and is easy to charge and discharge. It is not affected by external climate and temperature. The performance is stable and reliable, and it plays a great role in all aspects of modern social life.

[0003] Surface brushing is a surface treatment method that forms lines on the surface of the workpiece through grinding products to achieve decorative effects. Since surface brushing can reflect the texture of metal materials, it has been loved by more and more users and has been used more and more widely. Wire drawing of battery shells can form a uniform bottom layer on the surface, which enhances the surface's rust resistance. The milk retention rate of wire drawing plays a role in protecting the surface from rust and corrosion. In addition, wire drawing can effectively reduce the heat treatment temperature, shorten the process, improve efficiency, and reduce costs.

[0004] When an existing processing device performs wire drawing on the surface of a battery shell, it is necessary to manually place the workpiece of the battery shell into a fixture on a workpiece table and clamp it, then push the workpiece and the fixture under the sanding belt and start the pneumatic pressure block to make the sanding belt contact the workpiece for grinding and drawing. During the grinding process, coolant will be continuously sprayed on the workpiece to avoid excessive temperature during grinding and drawing.

[0005] The above-mentioned prior art solutions have the following defects: during the processing, the abrasive belt runs at high speed to grind the workpiece, and there is a lack of isolation device, so there is a risk that the on-site operator will misoperate and cause the body parts to be caught in the abrasive belt.
