[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, an electrode sheet is placed on the top of a conveyor belt, and a motor is started. The motor drives the rotating shaft to rotate, and the rotating shaft drives the first roller to rotate. The first roller drives the conveyor belt to rotate. During the rotation of the conveyor belt, the electrode sheet is transported. When the electrode sheet moves to the bottom of the working plate, the motor is turned off, and the electric telescopic rod is started. The electric telescopic rod drives the working plate to move downward, and the working plate drives the bending plate to move downward. During the downward movement of the bending plate, the electric telescopic rod contacts the top of the slider, so that the slider moves downward along the inner wall of the limiting groove. The slider drives the rotating rod to move downward. The slider is limited by the working shell, and the rotating rod drives the clamping shell to slide along the inner wall of the working shell. The two clamping shells approach each other, and the clamping shell drives the sliding plate to move. During the movement of the two sliding plates, the electrode sheet can be clamped, which is convenient for the subsequent coating operation of the electrode sheet and prevents the displacement of the electrode sheet during the coating process. When subjected to the reaction force of the electrode sheet, the electrode sheet will drive the sliding plate to move toward the inside of the clamping shell to prevent the device from getting stuck when clamping electrode sheets of different specifications, thereby improving the operation stability of the device.

[0017] (2) In the present invention, when the sliding plate moves toward the inside of the clamping shell, the sliding plate drives the rotating bar to move, which is limited by the limiting hole. The rotating bar drives the sliding frame to slide along the outer wall of the limiting hole. The sliding frame drives the vertical rod to move. The two vertical rods move away from each other. During the movement of the vertical rod, it contacts the horizontal plate and pushes the horizontal plate, so that the horizontal plate drives the moving frame to slide inside the card slot. The moving frame drives the square shell to move. The square shell drives the coating roller to move. The coating roller moves on the top of the electrode sheet, thereby coating the electrode sheet. When the two coating rollers gradually no longer contact the top of the electrode sheet, the worker The working plate continues to move downward, the working plate drives the gear to move downward, the gear drives the fixed sleeve to move downward, the fixed sleeve drives the cross scraper to move downward, so that the cross scraper can contact the top of the electrode sheet, and at the same time, when the movable frame moves, the movable frame drives the rack to move, and the rack will mesh with the side wall of the gear during the movement, so that the gear rotates, the gear drives the fixed sleeve to rotate, the fixed sleeve drives the cross scraper to rotate, and the cross scraper rotates on the top of the electrode sheet, thereby evenly scraping the paint adhered to the top of the electrode sheet, improving the uniformity of the electrode sheet coating and the quality of the electrode sheet manufacturing.

[0018] (3) In the process of the two clamping shells of the present invention approaching each other, the clamping shell drives the connecting block to move, and the connecting block drives the rotating plate to move. Limited by the bending rod, the rotating plate drives the concave shell to slide along the outer wall of the bending rod, and the concave shell drives the connecting rod to move, and the connecting rod drives the scraping plate to move. During the movement of the scraping plate, it will come into contact with the bottom of the conveyor belt in a stagnant state, and scrape off the paint attached to the bottom of the conveyor belt to prevent the previously coated electrode sheet from remaining and adhering to the outer wall of the conveyor belt, affecting the stable transportation of subsequent electrode sheets, and improving the coating stability of subsequent electrode sheets. When the coating is completed, the electric telescopic rod is started again to make the working plate reset and rise. At this time, the motor is started, and the motor makes the conveyor belt run. The conveyor belt drives the coated electrode sheet to transport. The moving electrode sheet will come into contact with the bottom of the cleaning plate. The scraping of the cleaning plate further prevents uneven coating on the top of the electrode sheet.
