The die-cutting mechanism has a pressure plate 7, and a second clamp 6 is connected to the pressure plate 7, and the upper mold is clamped in the second clamp 6. The upper mold and the lower mold are arranged opposite to each other.

[0017] The first clamp 5 includes a clamp body 51, a fixed plate 53, a movable plate 54, a first rotating seat 55, a second rotating seat 56, a lead screw 57, and a crank handle 58. The clamp body 51 has a groove 52. The first rotating seat 55 and the second rotating seat 56 are respectively located at both ends of the groove 52. Both ends of the lead screw 57 are rotatably connected to the first rotating seat 55 and the second rotating seat 56. The movable plate 54 is screwed to the middle of the lead screw 57, and the crank handle 58 is connected to one end of the lead screw 57. The fixed plate 53 is connected to one end of the clamp body 51, and the portion of the movable plate 54 extending from the groove 52 is flush with the fixed plate 53. The two ends of the lower template are clamped by the movable plate 54 and the fixed plate 53. The first clamp 5 and the second clamp 6 have the same structure and are symmetrically arranged vertically.

[0018] The blanking mechanism includes a motor 8, a coupling 9, a pair of brackets 10, a worm gear 11, a worm 12, several guide rods 13, a pressure rod 14, a receiving plate 15, several springs 17, a rotating shaft 19, an eccentric wheel 20, and a bearing 21. The guide rods 13 are fixedly connected to the pressure plate 7. The frame 18 is provided with several through holes. The guide rods 13 are slidably connected to the through holes. The springs 17 are sleeved on the guide rods 13. The two ends of the springs 17 are fixedly connected to the frame 18 and the pressure plate 7, respectively.

[0019] The motor 8 and a pair of brackets 10 are connected to the frame 18. The two ends of the worm gear 12 are rotatably connected in the brackets 10. The output shaft of the motor 8 is connected to the worm gear 12 through a coupling 9. The top of the frame 18 is provided with an opening 16, in which a worm wheel 11 is provided. The worm wheel 11 is meshed with the worm gear 12. A rotating shaft 19 is connected to the center of the worm wheel 11. The end of the rotating shaft 19 is connected to the side of the opening 16. An eccentric wheel 20 is fixedly connected to the rotating shaft 19. The eccentric wheel 20 is fixedly connected to the inner ring of the bearing 21. The pressure rod 14 is fixedly connected to the middle of the pressure plate 7. The top of the pressure rod 14 is connected to a receiving plate 15. The receiving plate 15 abuts against the lower part of the outer ring of the bearing 21.

[0020] In summary, the principle of the battery production insulating sheet punching device shown in this utility model is as follows: A first clamp 5 and a second clamp 6 are provided. The lower mold plate is held in the first clamp 5, and the upper mold plate is held in the second clamp 6. When it is necessary to change the mold, the first clamp 5 and the second clamp 6 are opened, the upper and lower mold plates are removed, and new upper and lower mold plates are replaced, thus completing the replacement. The operation is simple and easy, takes little time, and improves work efficiency. It is especially suitable for situations where it is necessary to frequently change the punching of different types of insulating sheets.

[0021] By rotating the crank handle 58, the lead screw 57 is driven to rotate in the first rotating seat 55 and the second rotating seat 56. Since one end of the movable plate 54 extends into the groove 52, it is blocked by the inner wall of the groove 52 and cannot rotate. It can only move along the axial direction of the lead screw 57 towards the fixed plate 53 until the lower template is clamped between the movable plate 54 and the fixed plate 53. The operation is simple, flexible and convenient.

[0022] The motor 8 is started, driving the worm gear 12 to rotate. The worm gear 12 drives the worm wheel 11 to rotate, forming a worm wheel 11 and worm gear 12 reduction structure, which increases the torque. The worm wheel 11 drives the eccentric wheel 20 to rotate through the rotating shaft 19. When the eccentric wheel 20 rotates, it frequently presses down on the receiving plate 15 and the pressure rod 14 through the bearing 21. Because the guide rod 13 slides up and down in the through hole, the pressure plate 7 can only move up and down. The spring 17 generates elastic force, constantly pulling the pressure plate 7 towards the top of the frame 18. Therefore, the pressure rod 14 drives the pressure plate 7 to move downward periodically. Since the pressure plate 7 is connected to the second clamp 6, and the upper template is connected to the second clamp 6, the insulating sheet is punched when the upper template and the lower template are closed.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
