[0002] A battery cell consists of a positive electrode, a negative electrode, an electrolyte, and a separator. Battery cells are used in consumer electronics, new energy vehicles, energy storage, and other fields. Their applications are very broad. During processing, a molding adhesive needs to be applied to the surface of the battery cell to ensure its performance. The molding adhesive application machine requires a compaction and leveling mechanism. However, existing compaction and leveling mechanisms have some shortcomings. To meet market needs, a new compaction and leveling mechanism for battery cell molding adhesive application machines is required.

[0003] Existing compaction and leveling mechanisms are not efficient enough when applying molding adhesive to the surface of battery cells. Furthermore, these mechanisms typically lack the ability to compact and adhere the molding paper tightly to the battery cell surface, resulting in insufficient adhesion. Additionally, existing compaction and leveling mechanisms cannot level and apply the molding adhesive, preventing the other end of the molding paper from being attached to the bottom of the battery cell, thus reducing the automation level of the molding paper application process. Utility Model Content

[0004] The purpose of this utility model is to provide a compaction and leveling mechanism for a battery cell adhesive applicator, so as to solve the problems mentioned in the background art that the compaction and leveling mechanism usually does not have the function of compacting and adhering the molding paper on the surface of the battery cell, and cannot level and apply the molding adhesive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compaction and leveling mechanism for a battery cell adhesive applicator, comprising a frame, a base plate below the frame, a turntable on the surface of the base plate, a movable seat mounted on the bottom surface of the frame, a lifting seat on the frame, a leveling and applicating mechanism on the frame for leveling the adhesive applied to the battery cell surface, and a compaction and pressing mechanism on the turntable for compacting the adhesive applied to the battery cell surface.

[0006] Preferably, the surfaces of the turntable and the base plate rotate in relation to each other.

The surface of the base plate is provided with guide strips. The guide strips slide in relation to the surface of the movable seat. The lifting seat slides in relation to the surface of the mechanism frame.

[0007] Preferably, the leveling and covering mechanism is composed of a cylinder push plate, a first cylinder, a connecting plate, a leveling roller and a roller frame. The first cylinder is installed on the surface of the top position of the mechanism frame. The output end of the first cylinder passes through the mechanism frame and is fixed to the surface of the top position of the lifting seat. The connecting plate is installed on the surface of the lifting seat.

[0008] Preferably, a roller frame is mounted on the surface of the connecting plate by screws, and a leveling roller for leveling the molding adhesive on the surface of the battery cell is provided on the surface of the roller frame. The leveling roller and the inner wall of the roller frame rotate in relation to each other. A cylinder push plate is mounted on the bottom of the base plate, and the output end of the cylinder push plate is fixed to the surface at the bottom position of the moving seat.

[0009] Preferably, the compaction and bonding mechanism includes a compaction frame, a second cylinder, a third cylinder, a fixing frame, a connecting rod, a compaction seat, a compaction plate, and a lower pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the compaction and leveling mechanism used in the battery cell adhesive applicator not only ensures the tightness of the forming paper on the surface of the battery cell when the compaction and leveling mechanism is used, making the forming paper adhere more firmly, but also allows the other end of the forming paper to be adhered to the bottom surface of the battery cell when the compaction and leveling mechanism is used, making the degree of automation of the forming paper application process of the compaction and leveling mechanism higher. 1.

[0015] The present invention provides a compaction and leveling mechanism for a battery cell adhesive applicator, as shown in the following structure. Figure 1 and Figure 2 As shown, the device includes a frame 1, a base plate 10 below the frame 1, a turntable 11 on the surface of the base plate 10, a movable seat 16 mounted on the bottom of the frame 1, and a lifting seat 13 on the surface of the frame 1. The turntable 11 and the surface of the base plate 10 rotate in relation to each other. The surface of the turntable 11 is provided with multiple sets of holding plates 12 for storing battery cells. The holding plates 12 are mounted on the surface of the turntable 11 with the turntable 11 as the circumference. The device is also equipped with a PLC controller. Multiple sets of clamping cylinders 14 for clamping and limiting the battery cells are mounted on one side of the holding plates 12 on the surface of the turntable 11. The input end of the clamping cylinder 14 is electrically connected to the output end of the PLC controller. The surface of the base plate 10 is provided with a guide plate 15, which slides in relation to the surface of the movable seat 16. The lifting seat 13 slides in relation to the surface of the frame 1.

[0016] Furthermore, such as Figure 1 and Figure 3 As shown, a leveling and bonding mechanism 2 is provided on the surface of the frame 1. This leveling and bonding mechanism 2 is used to level the molding adhesive applied to the surface of the battery cell. The leveling and bonding mechanism 2 consists of a cylinder push plate 21, a first cylinder 22, a connecting plate 23, a leveling roller 24, and a roller frame 25. The first cylinder 22 is installed on the surface at the top of the frame 1. The first cylinder 22 can be of the SC series. The input end of the first cylinder 22 is electrically connected to the output end of the PLC controller. The output end of the first cylinder 22 passes through the frame 1 and is connected to the PLC controller. The surface at the top of the lifting seat 13 is fixed. A connecting plate 23 is installed on the surface of the lifting seat 13. A roller frame 25 is installed on the surface of the connecting plate 23 by screws. A leveling roller 24 for leveling the molding adhesive on the surface of the battery cell is provided on the surface of the roller frame 25. The leveling roller 24 and the inner wall of the roller frame 25 rotate and cooperate with each other. A cylinder push plate 21 is installed at the bottom of the base plate 10. The input end of the cylinder push plate 21 is electrically connected to the output end of the PLC controller. The output end of the cylinder push plate 21 is fixed to the surface at the bottom of the moving seat 16.

[0017] During implementation, the control cylinder push plate 21 operates, causing the movable seat 16 to slide on the surface of the guide plate 15. At this time, the movable seat 16 drives the mechanism frame 1 to move towards the turntable 11. When the mechanism frame 1 moves, it drives the lifting seat 13, connecting plate 23, leveling roller 24, and roller frame 25 to move towards one side of the turntable 11, causing the surface of the leveling roller 24 to contact the surface of the molding adhesive on the side of the battery cell. Subsequently, the PLC controller controls the first cylinder 22 to operate, causing the lifting seat 13 to move downwards on the surface of the mechanism frame 1. When in motion, the lifting seat 13 drives the connecting plate 23 to move downward. At this time, the connecting plate 23 drives the leveling roller 24 and the roller frame 25 to move downward to below the battery cell. At this time, the leveling roller 24 rotates on the surface of the roller frame 25. Under the action of the leveling roller 24, the molding adhesive applied to the side of the battery cell can be compacted. Subsequently, the cylinder push plate 21 continues to drive the moving seat 16 and the mechanism frame 1 to move, so that the leveling roller 24 moves to below the battery cell. The leveling roller 24 applies the other end of the molding paper on the surface of the battery cell to the bottom surface of the battery cell. Under the action of the leveling roller 24, the molding adhesive on the bottom surface of the battery cell can be compacted, so as to realize the function of compacting and leveling the application of the leveling mechanism.

[0018] Furthermore, such as Figure 2 and Figure 4 As shown, a compaction and bonding mechanism 3 is provided on the surface of the turntable 11. This compaction and bonding mechanism 3 is used to compact the molding adhesive applied to the surface of the battery cell. The compaction and bonding mechanism 3 includes a compaction frame 31, a second cylinder 32, a third cylinder 33, a fixing frame 34, a connecting rod 35, a compaction seat 36, a compaction plate 37, and a lower pressure plate 38. The compaction frame 31 is installed on the surface of the top position of the turntable 11. The second cylinder 32 is installed on the inner side of the compaction frame 31. The model of the second cylinder 32 can be selected from the SC series. The input end of the second cylinder 32 is electrically connected to the output end of the PLC controller. The lower pressure plate 38 is installed on the output end of the second cylinder 32. The surface of the compaction frame 31 is equipped with a compaction and bonding mechanism 3. The third cylinder 33, which can be of the SC series, has its input terminal electrically connected to the output terminal of the PLC controller. A mounting bracket 34 is installed on the surface of the third cylinder 33, and a compaction seat 36 is provided on the surface of the mounting bracket 34. A connecting rod 35 is installed on the surface of the bottom position of the mounting bracket 34, and the bottom end of the connecting rod 35 extends into the interior of the compaction seat 36. A high-elasticity spring 39 is fitted on the surface of the connecting rod 35, and the bottom end of the high-elasticity spring 39 is fixed to the surface of the top position of the compaction seat 36. The top end of the high-elasticity spring 39 is fixed to the surface of the bottom position of the mounting bracket 34. A compaction plate 37 is installed on the surface of the compaction seat 36 by screws.

[0019] During implementation, the second cylinder 32 on the surface of the compaction frame 31 operates, driving the lower pressure plate 38 downward. The lower pressure plate 38 presses the battery cell against the surface of the material holding plate 12, ensuring stability during battery cell processing. Subsequently, the PLC controller controls the third cylinder 33 on the surface of the compaction frame 31 to operate, driving the compaction plate 37 downward. At this time, because a high-elasticity spring 39 is fitted on the surface of the connecting rod 35, when the compaction plate 37 moves downward to contact the surface of the battery cell... When the surfaces of the molding adhesive come into contact, the compaction plate 37 applies a certain force upward, and the compaction plate 37 drives the compaction seat 36 to move slightly on the surface of the connecting rod 35. At this time, the high-elastic spring 39 fitted on the surface of the connecting rod 35 is compressed. Under the action of the high-elastic spring 39, the compaction plate 37 can play a flexible buffering effect. Under the action of the compaction plate 37, the molding adhesive on the surface of the battery cell is compacted. At the same time, the stability of the battery cell during processing can be ensured, so as to realize the function of the compaction and leveling mechanism to compact and adhere the molding paper on the surface of the battery cell.

[0020] Working Principle: In use, the frame 1 is first placed in the designated position. The battery cells are fed onto the surface of the holding plate 12 via the conveyor belt and feeding module. The PLC controller controls the clamping cylinder 14 to clamp the battery cells on the surface of the holding plate 12. Then, the turntable 11 rotates on the surface of the base plate 10. When the turntable 11 moves the holding plate 12 containing the battery cells to one side of the frame 1, a CCD camera is mounted on the surface of the frame 1. The CCD camera first takes a picture of the battery cell surface. Then, the PLC controller controls the second cylinder 32 on the surface of the compaction frame 31 to operate. Under the action of the second cylinder 32, the lower pressure plate 38 moves downwards, pressing the battery cells onto the surface of the holding plate 12, ensuring the stability of the battery cells during processing. Finally, the PLC controller controls the compaction frame 31 to... The third cylinder 33 operates, driving the compaction plate 37 downward. At this time, due to the high-elasticity spring 39 mounted on the surface of the connecting rod 35, when the compaction plate 37 moves downward to contact the surface of the molding adhesive on the battery cell, the compaction plate 37 will apply a certain force upward. The compaction plate 37 will drive the compaction seat 36 to move slightly on the surface of the connecting rod 35. At this time, the high-elasticity spring 39 mounted on the surface of the connecting rod 35 is compressed. Under the action of the high-elasticity spring 39, the compaction plate 37 can play a flexible buffering effect. Under the action of the compaction plate 37, the molding adhesive on the surface of the battery cell is compacted. At the same time, it can ensure the stability of the battery cell during processing, so as to realize the function of the compaction and leveling mechanism to compact and adhere the molding paper on the surface of the battery cell. Thus, when the compaction and leveling mechanism is used, it can ensure the tight adhesion of the molding paper to the surface of the battery cell, making the molding paper adhere more firmly.

[0021] Subsequently, the PLC controller controls the cylinder pusher plate 21 to operate. Under the action of the cylinder pusher plate 21, the moving seat 16 slides on the surface of the guide plate 15. At this time, the moving seat 16 drives the mechanism frame 1 to move towards the turntable 11. When the mechanism frame 1 moves, it drives the lifting seat 13, connecting plate 23, leveling roller 24, and roller frame 25 to move towards one side of the turntable 11, so that the surface of the leveling roller 24 moves to contact the surface of the molding adhesive on the side of the battery cell. Then, the PLC controller controls the first cylinder 22 to operate. Under the action of the first cylinder 22, the lifting seat 13 moves downward on the surface of the mechanism frame 1. When the lifting seat 13 moves downward, it drives the connecting plate 23 to move downward. At this time, the connecting plate 23 drives the leveling roller 24 to move downward. The roller frame 25 moves downwards to below the battery cell. At this time, the leveling roller 24 rotates on the surface of the roller frame 25. Under the action of the leveling roller 24, the molding adhesive applied to the side of the battery cell can be compacted. Subsequently, the cylinder push plate 21 continues to drive the moving seat 16 and the mechanism frame 1 to move, so that the leveling roller 24 moves to below the battery cell. The leveling roller 24 applies the other end of the molding paper on the surface of the battery cell to the bottom surface of the battery cell. Under the action of the leveling roller 24, the molding adhesive on the bottom surface of the battery cell can be compacted, so as to realize the function of leveling and applying the compacting and leveling mechanism. This allows the compacting and leveling mechanism to apply the other end of the molding paper to the bottom surface of the battery cell when in use, making the automation level of the compacting and leveling mechanism when applying the molding paper higher, and finally completing the use of the compacting and leveling mechanism.
