[0002] During the production process of battery electrodes, the electrode strips must be punched. The existing punching method uses a die-cutting machine to cut the strips into the desired electrode shapes. After die-cutting, the electrodes and the trimmings are delivered together. After the trimmings are removed, the electrodes remain on a traction belt, where workers collect the electrodes. During the removal of the trimmings, the electrodes can be easily moved, causing them to be placed in a disorderly manner on the traction belt, hindering electrode collection. Furthermore, because the electrode strips are flexible strips with intermittent coatings, wrinkles or tilts when entering the die-cutting machine can affect die-cutting quality.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figure 1-4 , a sodium battery pole piece laminating device, including a mounting frame 1. Inside the mounting frame 1, a conveyor belt 2 is provided. On one side of the mounting frame 1, a material guiding component is provided. The material guiding component includes two second springs 11 and two material guiding plates 12. The two material guiding plates 12 are respectively hinged on the inner walls of both sides of the mounting frame 1. The two ends of the second spring 11 are respectively fixed to the material guiding plate 12 and the inner wall of the mounting frame 1. The two material guiding plates 12 are in an eight-shaped structure. By laying the pole piece strip flat on the conveyor belt 2, the pole piece strip is placed between the two material guiding plates 12. The second spring 11 is used to adjust the material guiding plates 12, so that the two material guiding plates 12 adapt to the pole piece strip, and then the two material guiding plates 12 are used to limit the pole piece strip, making the pole piece strip lay flat neatly.

[0021] Inside the mounting frame 1, a lower template 3 is fixedly provided. A plurality of die cavities 4 are opened on the lower template 3. On the mounting frame 1, a U-shaped frame 5 is fixedly provided. At the top of the U-shaped frame 5, a cylinder 6 is fixedly provided. The output end of the cylinder 6 is fixedly provided with an upper die seat 7. A plurality of telescopic columns 8 penetrate through one side of the upper die seat 7. At the bottom ends of the plurality of telescopic columns 8, pressing blocks 9 are fixedly provided. At the upper ends of the plurality of telescopic columns 8, first springs 10 are sleeved. At the top ends of the telescopic columns 8, a top block 14 is fixedly provided. The two ends of the first spring 10 are respectively fixed to the top block 14 and the upper die seat 7. At the bottom of the upper die seat 7, a plurality of cutting blocks 20 adapted to the die cavities 4 are fixedly provided. By driving the upper die seat 7 to move downward by the cylinder 6, the plurality of pressing blocks 9 contact the pole piece strip. By squeezing the telescopic columns 8 upward, the first spring 10 is stretched. Then, under the action of the restoring force of the first spring 10, the plurality of pressing blocks 9 are driven to press the pole piece strip tightly, so that when the pole piece strip is cut, it is not easy to displace, ensuring the cutting accuracy. By driving the cutting blocks 20 to move downward by the upper die seat 7, the plurality of die cavities 4 on the lower template 3 are used to cut the pole piece.

[0022] On the outer wall of the mounting frame 1, a motor 15 is fixedly provided. Inside the mounting frame 1, a winding shaft 19 is rotatably provided. The output end of the motor 15 is fixed to the winding shaft 19. By driving the winding shaft 19 to rotate by the motor 15, the corner materials of the pole piece strip are wound up.

[0023] A blanking plate 13 is hingedly mounted on the inner sidewall of the mounting frame 1. A buffer assembly, comprising a damper 16 and a third spring 17, is disposed at the bottom of the mounting frame 1. A support plate 18 is fixedly mounted at the bottom of the mounting frame 1. The top and bottom ends of the damper 16 are hingedly connected to the blanking plate 13, and the third spring 17 is sleeved around the outside of the damper 16. The damper 16 is tilted, and the ends of the third spring 17 are fixed to the support plate 18 and the blanking plate 13, respectively. The cut pole pieces fall onto the conveyor belt 2 and, after being transported by the conveyor belt 2, fall onto the blanking plate 13. By pressing the blanking plate 13 downward, the damper 16 is compressed, and the third spring 17 is compressed, providing a buffer, preventing the pole pieces from being significantly impacted and minimizing damage. After being unloaded from the blanking plate 13, the pole pieces can be easily packaged, collected, and stacked.

[0024] The operating principle of the present invention is described as follows: the pole piece material strip is laid flat on the conveyor belt 2, so that the pole piece material strip is placed between the two guide plates 12, and the guide plates 12 are adjusted by the second spring 11 so that the two guide plates 12 adapt to the pole piece material strip, and then the pole piece material strip is limited by the two guide plates 12 so that the pole piece material strip is laid flat and neat, and the pole piece material strip passes through the upper surface of the lower template 3, and the upper mold base 7 is driven downward by the cylinder 6 to make multiple pressing blocks 9 contact the pole piece material strip, and the telescopic column 8 is squeezed upward to stretch the first spring 10, and then the restoring force of the first spring 10 drives multiple The pressing block 9 presses the electrode material strip so that the electrode material strip is not easily displaced during cutting, thereby ensuring the cutting accuracy. The cutting block 20 is driven downward by the upper mold base 7 to cooperate with the multiple mold cavities 4 on the lower template 3 to cut the electrode. The cut electrode falls on the conveyor belt 2, and after being transported by the conveyor belt 2, it falls onto the blanking plate 13. By squeezing the blanking plate 13 downward, the blanking plate 13 squeezes the damper 16, and cooperates with the compression of the third spring 17 to perform buffering, so that the electrode falling from the conveyor belt 2 will not be subjected to a large impact, and damage is avoided as much as possible. After unloading through the blanking plate 13, it is convenient for the staff to pack, collect and stack.
