Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a lithium battery core shelling device. Background Art

[0002] In the automated production process of batteries, there are some differences in the corresponding production processes for different types of batteries. In some battery production processes, it is necessary to involve the shelling of battery cells. For example, during the production process of wearable soft-board lithium batteries, the battery cells need to be assembled in a plastic shell. Before shelling, the battery cell usually has a protective plate welded on the head part, and the protective plate is in a bent state. At this time, the soft plate at the tail of the protective plate is located close to the battery cell body. Therefore, during the shelling process of the battery cell, the soft plate of the protective plate close to the battery cell body is easy to interfere with the shelling operation, affecting the normal shelling operation of the battery cell.

[0003] In the prior art, a soft board adsorption unit is usually provided on the battery cell transport mechanism to fix the soft board. However, since the soft board is in a state of being close to the battery cell body before being fixed, the soft board cannot maintain a long distance from the battery cell body when being fixed by the soft board adsorption unit, resulting in the risk of the soft board still interfering with the battery cell shelling operation. Utility Model Content

[0035] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] refer to Figures 1 to 4 The lithium battery cell shelling equipment provided by the utility model includes a cell transport mechanism 1, a cell conveying mechanism 2 located on the working path of the cell transport mechanism 1, and a soft plate mechanism 3 located in the conveying direction of the cell conveying mechanism 2. The soft plate mechanism 3 is used to move the soft plate of the cell protection plate to open the soft plate. It can be understood that when the cell is moved from the previous station to the cell conveying mechanism 2, the protective plate has been welded to the head of the cell, and the protective plate is in a bent state. At this time, the soft plate at the tail of the protective plate is located close to the cell body. The soft plate mechanism 3 can move the soft plate of the cell protection plate to an open state, so that the soft plate of the protective plate is away from the cell body.

[0039] Furthermore, the battery cell transport mechanism 1 includes a first driving module 11, a battery cell fixing module 12 and a soft board fixing module 13, the battery cell fixing module 12 and the soft board fixing module 13 are both connected to the driving end of the first driving module 11, and the soft board fixing module 13 is used to fix the soft board in an open state. In some embodiments, the first driving module 11 is a robotic arm. The specific operation process is that the battery cell is loaded onto the battery cell conveying mechanism 2 from the previous station, the battery cell conveying mechanism 2 transfers the battery cell to the position of the soft board mechanism 3 to perform the soft board operation, and then the battery cell transporting mechanism 1 transfers the battery cell to the shelling station to perform the battery cell shelling operation.

[0040] As a further optimization, the soft board fixing module 13 includes an adsorption unit 131 and a clamping unit 132. The adsorption unit 131 is used to fix one end of the soft board close to the battery cell body, and the clamping unit 132 is used to fix one end of the soft board away from the battery cell body. The adsorption unit 131 and the clamping unit 132 are both connected to the driving end of the first driving module 11, and can move together under the drive of the first driving module 11. The clamping unit 132 includes a clamping claw and a clamping drive cylinder that drives the clamping claw to loosen or clamp. It should be noted that the orientation of the adsorption surface of the adsorption unit 131 matches the orientation of the soft board in the open state, so that when the adsorption unit 131 adsorbs the soft board, it can ensure that the soft board and the adsorption surface of the adsorption unit 131 are completely in contact, achieving good adsorption and fixing effects.

[0041] The end of the soft board close to the battery body is adsorbed and fixed by the adsorption unit 131, and the end of the soft board away from the battery body is clamped and fixed by the clamping unit 132, so that the soft board can be better fixed. It can effectively prevent the soft board from interfering with the battery shell installation operation, and prevent the soft board from being scratched or scratched during the operation, thereby protecting the soft board.

[0042] As a further optimization, the driving end of the first driving module 11 is connected to a lifting driving cylinder, and the battery cell fixing module 12 and the adsorption unit 131 are both connected to the driving end of the lifting driving cylinder. The lifting driving cylinder drives the movement of the battery cell fixing module 12 and the adsorption unit 131, so as to change the relative position relationship between the battery cell fixing module 12, the adsorption unit 131 and the clamping unit 132, so as to adapt to different specifications of protection board soft boards and meet different operation requirements.

[0043] As a further optimization, the soft board mechanism 3 includes a second driving module 31 and a toggle member 32 connected to the driving end of the second driving module 31. The second driving module 31 can drive the toggle member 32 to move to the soft board station and complete the soft board toggle action. As one embodiment, the contact portion of the toggle member 32 with the soft board is a cylindrical structure. The circular arc surface of the cylindrical structure contacts the soft board to perform the soft board toggle action, which can reduce the friction between the toggle member 32 and the soft board, which can prevent the soft board from being scratched by the toggle member 32 and play a protective role, and can also improve the smoothness of the soft board operation and improve the operation efficiency.

[0044] In some embodiments, the second driving module 31 includes a first driving cylinder 311 for driving the toggle member 32 to extend or retract and a second driving cylinder 312 for driving the toggle member 32 to toggle the soft board. As one embodiment, the toggle member 32 is connected to the driving end of the second driving cylinder 312, and the fixed end of the second driving cylinder 312 is connected to the driving end of the first driving cylinder 311. In some embodiments, the soft board can be removed by driving the toggle member 32 to move horizontally by the second driving cylinder 312, or by driving the toggle member 32 to move obliquely upward by the second driving cylinder 312.

[0046] As a further optimization of Example 1, refer to Figures 5 and 6 The cell conveying mechanism 2 includes a first movable module 21 and a cell positioning platform 22 connected to the driving end of the first movable module 21. In some embodiments, a cell placement position is provided on the cell positioning platform 22, and the size and shape of the cell placement position match the size and shape of the cell, so that when the cell is placed on the cell placement position, the cell can be preliminarily positioned.

[0047] As a further optimization, the lithium battery cell shelling equipment also includes a cell secondary positioning mechanism 4, which includes a lateral positioning module 41 and a head positioning module 42. The lateral positioning module 41 is located on the cell positioning platform 22, and the head positioning module 42 is located in the conveying direction of the cell conveying mechanism 2. In some embodiments, the lateral positioning module 41 is located on the side of the cell placement position, and a retaining wall is provided on the side of the cell placement position relative to the lateral positioning module 41. The lateral positioning module 41 can push the cell against the retaining wall to achieve lateral positioning of the cell, and the head positioning module 42 can push the head of the cell to achieve positioning of the head of the cell. Through the cooperation of the lateral positioning module 41 and the head positioning module 42, the secondary positioning of the cell before the soft board is moved can be achieved, ensuring that the subsequent soft board mechanism 3 is accurately aligned with the position of the soft board for moving, thereby improving the accuracy of the operation.

[0048] In some embodiments, the lithium battery cell casing device further includes a paper peeling and attaching mechanism 5 located on the working path of the cell transport mechanism 1, and the paper peeling and attaching mechanism 5 includes a rotating cylinder 51 and a clamping module 52 connected to the driving end of the rotating cylinder 51. In some embodiments, the clamping module 52 includes a clamping claw and a clamping driving cylinder that drives the clamping claw to loosen or clamp.

[0049] It should be noted that when the battery cell is transferred to the paper peeling station, the battery cell is in a horizontal state, the bottom surface of the battery cell is affixed with PSA tape, and the side of the PSA tape facing away from the battery cell is affixed with attachment paper, and a convex ear structure in a suspended state is formed at the edge of the attachment paper, and the clamping module 52 is used to clamp the convex ear structure. The clamping module 52 moves downward under the rotation drive of the rotating cylinder 51, so that the attachment paper peels off the PSA tape, completing the attachment paper peeling action. In some embodiments, an attachment paper bin can be provided below the paper peeling mechanism 5 to store the torn attachment paper.
