Description

Technical Field

[0001] The utility model relates to the technical field of plate manufacturing for battery production, and specifically relates to a plate flattening device for battery production. Background Art

[0002] During the battery production process, the separator that needs to be flattened is an important part of the battery structure. The separator, also known as a diaphragm or separator, is one of the key components inside the battery. It is located between the positive and negative electrodes of the battery. Its main function is to prevent short circuits caused by direct contact between the positive and negative electrodes, and at the same time allow the ions required for the battery reaction to pass through, so as to ensure that the battery can be charged and discharged normally. The separator isolates the positive and negative plates of the battery and is usually made of porous materials such as microporous plastics or glass fibers. During the assembly process, it is necessary to ensure the flatness and dimensional accuracy of the separator so that it can be correctly placed inside the battery.

[0003] However, in the existing separator flattening devices, the flattening components of the separator are mostly single-direction mechanical pressing devices in order to pursue simple and light structures. When the flattening device presses from only one direction, the substrate may have a good flattening effect in the force direction, but in the non-force direction or the edge area, the flattening effect may be poor, resulting in unevenness on the surface of the substrate. Single-direction pressing may cause uneven stress distribution inside the substrate, and these internal stresses may gradually release during subsequent use, causing the substrate to deform or crack, affecting the overall quality and stability of the product.

By using the cooperation of the buckle block 23 and the limiting groove 20, it is convenient for the limiting lifting rod 19 to drive the lifting plate 22 to change its vertical position when rotating.

[0028] On the inner side surface of the outer shell 16, a bottom plate 21 is fixedly connected. One end of the limit lifting rod 19 is movably connected to one side surface of the bottom plate 21.

[0029] The transmission component 2 includes a motor 5. The motor 5 is fixedly connected to one side surface of the connecting frame 1. The output end of the motor 5 is fixedly connected with a rotating bevel gear 6. One side surface of the motor 5 is fixedly connected with a fixed bracket 10.

Embodiment 2

[0030] Based on the above Embodiment 1, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 ,one side surface of one of the linkage bevel gears 7 is fixedly connected with a first rotating rod 8, and one side surface of the other linkage bevel gear 7 is fixedly connected with a second rotating rod 9. The first rotating rod 8 is sleeved inside the second rotating rod 9. One end of the second rotating rod 9 is fixedly connected with one side surface of the outer shell 16. The linkage bevel gear 7 located at the upper position drives the first rotating rod 8 to rotate, and the linkage bevel gear 7 located at the lower position drives the second rotating rod 9 and the leveling component 3 as a whole to rotate. The first rotating rod 8 drives the components inside the leveling component 3 to rotate.

[0031] One end of the first rotating rod 8 is fixedly connected with a linkage gear 11. One side of the linkage gear 11 is provided with a meshing gear 12. The linkage gear 11 and the meshing gear 12 are meshed with each other. Both the lower ends of the linkage gear 11 and the meshing gear 12 are fixedly connected with reciprocating half gears 13. One side of the two reciprocating half gears 13 is provided with a reciprocating movable block 14. One side of the reciprocating movable block 14 is adapted to the two reciprocating half gears 13. One side surface of the two reciprocating half gears 13 is fixedly connected to one side surface of the positioning bracket 17. One side of the reciprocating movable block 14 is provided with a reciprocating pinion 18. The reciprocating pinion 18 is meshed with one side surface of the reciprocating movable block 14. One side surface of the reciprocating pinion 18 is fixedly connected to one end of the limit lifting rod 19. The first rotating rod 8 drives the linkage gear 11 to rotate. At the same time, due to the meshing connection between the meshing gear 12 and the linkage gear 11, the reverse rotation of the meshing gear 12 is realized, and at the same time, the rotation of the two reciprocating half gears 13 is driven. During the rotation process, the reciprocating movable block 14 will be cyclically buckled with the two reciprocating half gears 13, so as to drive the reciprocating movement of the reciprocating movable block 14. The lower end of the reciprocating movable block 14 is also meshed with the reciprocating pinion 18. When the reciprocating movable block 14 makes a reciprocating movement, it drives the reciprocating positive and negative rotation of the reciprocating pinion 18 and the limit lifting rod 19 connected thereto.

[0032] One end of the reciprocating movable block 14 is provided with a limit frame 15. The limit frame 15 is fixedly connected to the inner side surface of the connecting frame 1. The limit frame 15 plays a role in limiting and supporting the reciprocating movable block 14 to prevent the reciprocating movable block 14 from deviating in the moving direction.

[0033] Working principle: Please refer to Figures 1-5As shown, this overall structure is located inside the general equipment for lithium battery production and is interconnected with other equipment through the connecting frame 1. This overall device is used in combination with other devices. When this utility model is in use, the battery separator that needs to be leveled is placed inside the notch of the placing rack 4 by using the components of other devices. The external lifting component drives the connecting frame 1 to contract, thereby driving the motor 5 and the leveling component 3 to move downward, so that the leveling roller 26 at the lower end of the leveling component 3 contacts the separator. The motor 5 is connected to an external power source to provide sufficient power for the whole. The motor 5 is started, driving the rotating bevel gear 6 at the output end of the motor 5 to rotate synchronously, and at the same time driving the two linkage bevel gears 7 to rotate in reverse synchronously. The first rotating rod 8 drives the linkage gear 11 to rotate. At the same time, because the meshing gear 12 is meshed with the linkage gear 11, the reverse rotation of the meshing gear 12 is realized, and at the same time the rotation of the two reciprocating half gears 13 is driven. During the rotation process, the reciprocating moving block 14 will be cyclically buckled with the two reciprocating half gears 13, thereby driving the reciprocating movement of the reciprocating moving block 14. The lower end of the reciprocating moving block 14 is also meshed with the reciprocating pinion 18. When the reciprocating moving block 14 moves reciprocally, it drives the reciprocating positive and reverse rotation of the reciprocating pinion 18 and the limiting lifting rod 19 connected thereto. The gear inside the leveling component 3 is driven to rotate through the first rotating rod 8. Through the internal meshing connection relationship and the linkage relationship between various accessories, the reciprocating movement of the two leveling rollers 26 at the lower end of the leveling device is realized. Secondly, the second rotating rod 9 drives the overall rotation to realize the leveling rotation on the plane. Through the reciprocating movement and the plane rotation, the separator can receive a more uniform stress distribution during the leveling process, which helps to reduce the internal stress concentration phenomenon caused by leveling in a single direction, reduce the risk of deformation or crack caused by stress release during the use of the separator, improve the overall flatness of the separator, and reduce the performance impact caused by surface unevenness. When used as a whole, the performance of the device is improved, the required time and steps are reduced, and the overall practicability is improved. After that, the other devices of the general equipment for lithium battery production take out the leveled separator and put it into the production bus, and this device then levels the next separator.
