In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main components of the positive and negative electrodes are both lead sulfate. The battery is mainly composed of tubular positive plates, negative plates, electrolyte, separators, battery tanks, battery covers, poles, and liquid filling caps.

[0003] The plate casting machine, also known as the grid casting machine, is a necessary special equipment in the battery industry. Its main working principle is to inject the molten lead into the mold, cool it into shape, and then obtain the required grid product through transportation and trimming processes.

[0004] The plate casting machine includes a main body with a slide, a cutter device and a plate collecting mechanism. The cutter device is arranged at the end of the slide, and the plate collecting mechanism includes a flap and parallel arranged plate grid support rails. After the mold of the plate casting machine is opened, the formed plate grid blank falls into the slide, the cutter device cuts off the gate on the plate grid blank, the plate grid slides onto the flap, and is transferred from the flap to the support rail, and then collected manually.

In this device, the file is attached to the grid, and the cylinder drives the file on the slide plate to move back and forth to grind and remove the burrs on the edge of the grid, but it is only suitable for deburring one side of the grid, and the working efficiency is low.

[0006] The patent application document with publication number CN202308158U provides a tool for removing burrs from a grid, comprising a scraper with a blade and a handle fixed on the upper end face of the scraper at an angle toward the blade, wherein the handle is inclined at an angle of 60 degrees to the upper end face of the scraper, and the burrs on the edge of the grid are also cleaned by a manual scraper.

[0007] In order to reduce the burrs on the edge of the grid, the patent application document with publication number 201946688U provides a grid for reducing the burrs on the pole ears, the grid includes a grid body, and the pole ears and support bars are connected to the grid body, and the connection between the support bar and the pole ears is an oblique angle; the right angle at the bottom of the support bar is changed to an oblique angle, so that the burrs on the edge of the grid are reduced by changing the structure of the grid body.
