Abstract
Description
Technical Field
[0001] This application relates to the field of battery cell manufacturing technology, and in particular to a battery cell fixture with consistency testing and a battery cell tab shaping device. Background Technology
[0002] The battery cell production process involves steps such as bending and welding of the cell tabs. In current automated battery cell production lines, a turntable transfer method is typically used to improve production efficiency. Multiple cell clamping fixtures are placed on the turntable to hold the cells, which are then sequentially transferred to bending and welding stations located at the turntable's edge for processing. However, as production efficiency demands increase, the turntable's rotation speed also needs to increase. At high speeds, potential mechanical structural issues with the turntable and cell clamping fixtures can cause misalignment of the cells placed on the fixtures, leading to increased processing errors and affecting battery cell production quality. Utility Model Content
[0003] To address one of the aforementioned technical problems, this application provides a battery cell fixture with consistency detection capabilities. The fixture includes a mounting base mounted on a turntable mechanism for supporting the battery cells, and a detection mechanism located on one side of the turntable mechanism. A clamping assembly for fixing the battery cells is provided on the mounting base. An edge to be detected is formed on the end face or side of the mounting base. The detection mechanism includes a detection element and a displacement module that drives the detection element to move towards the edge to be detected. After the battery cells are loaded onto the mounting base, they are fixed by the clamping assembly, preventing positional displacement of the battery cells during rapid rotation of the turntable mechanism, thereby improving the processing accuracy of the battery cells. By filling the gap between the detection element and the mounting base with plug gauges or feeler gauges, the installation position of each mounting base on the turntable mechanism is determined based on the specifications and quantity of the plug gauges or feeler gauges placed in the gap. This corrects the position of each mounting base, ensuring the consistency of the battery cell position and improving the processing accuracy of the battery cells.
[0004] Preferably, the detection mechanism further includes a support base, the displacement module is mounted on the support base, and the detection element is connected to the drive end of the displacement module. The displacement module drives the detection element to move horizontally and vertically, allowing the detection element to approach the mounting base on the turntable mechanism. Thus, when calibrating the position of the mounting base, the detection element serves as a fixed reference for detection. The turntable mechanism sequentially moves the mounting bases to positions corresponding to the detection elements. By filling the gap between the detection element and the edge to be detected with plug gauges or feeler gauges, the consistency of the installation positions of each mounting base is determined based on the specifications and quantity of the plug gauges or feeler gauges placed in the gap.
[0005] Preferably, the clamping assembly includes a first driver disposed on the mounting base and a pressure block disposed at the driving end of the first driver. The first driver is used to drive the pressure block to press down on the battery cell on the mounting base. Thus, by driving the pressure block to press down on the surface of the battery cell through the first driver, the battery cell is fixed to the mounting base, preventing the battery cell from shifting position when the turntable mechanism rotates rapidly, thereby improving the processing accuracy of the battery cell.
[0006] Preferably, a tab shaping assembly is further provided on the mounting base above the pressure block. The tab shaping assembly is used to press down the tabs on the battery cell. The tab shaping assembly then causes the outward-facing tabs of the battery cell to bend vertically downwards, thereby adjusting the battery cell tabs to a suitable position to accommodate further bending of the tabs, such as a Z-shaped bend.
[0007] Preferably, the tab shaping assembly includes a bracket mounted on the mounting base, a lifting plate slidably mounted on the bracket, and a second driver for moving the lifting plate. A shaping block is provided at the bottom end of the lifting plate. After the battery cell is placed on the mounting base, the shaping block is positioned above the tab. The second driver drives the lifting plate to move up and down, so that when the shaping block descends, it can bend the outward-facing tab vertically downwards, thereby adjusting the battery cell tab to a suitable position and fixing the tab for further bending.
[0008] Preferably, a limit switch is provided on the mounting base below the lifting plate. The limit switch limits the descent position of the lifting plate, thereby preventing excessive descent and damage to the battery cell tabs.
[0009] Preferably, the bracket is provided with a guide post and guide sleeve structure, and the lifting plate is slidably mounted on the bracket through the guide post and guide sleeve structure. The guide post and guide sleeve structure consists of a guide post disposed on the bracket and a guide sleeve slidably disposed on the guide post. The guide sleeve is connected to the lifting plate, so that the lifting plate is slidably mounted on the bracket through the guide post and guide sleeve structure, allowing the lifting plate to move smoothly up and down on the bracket.
[0010] Preferably, the device further includes a fixed base mounted on the turntable mechanism. The mounting base is slidably disposed on the fixed base, and a third driver connected to the mounting base is disposed on the fixed base. The third driver then drives the mounting base to move up and down, thereby adjusting the height of the mounting base to cooperate with the detection mechanism in completing position calibration.
[0011] Preferably, a battery cell tab shaping device includes the aforementioned battery cell fixture with consistency detection, and a shaping mechanism disposed on the conveying path of the turntable mechanism, with an auxiliary shaping component disposed on one side of the shaping mechanism. The auxiliary shaping component guides the end of the battery cell tab, preventing the tab end from drooping during transportation and keeping the tab in a horizontal state.
[0012] Preferably, the auxiliary shaping component includes a guide block, one end of which has an arc-shaped guide surface. The drooping tab is then corrected by the arc-shaped guide surface, keeping the tab horizontal before entering the shaping mechanism, thereby improving the subsequent bending effect.
[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application sets multiple mounting seats on the turntable mechanism and a detection mechanism located on one side of the turntable mechanism. After the battery cell is fed into the mounting seat, it is fixed by a clamping component, which prevents the battery cell from shifting position when the turntable mechanism rotates rapidly, thereby improving the processing accuracy of the battery cell. An edge to be detected is formed on the end face or side of the mounting seat. The detection mechanism includes a detection component and a displacement module that drives the detection component to move toward the edge to be detected. The detection component serves as a reference for detection. Before operation, the turntable mechanism moves the mounting seats one by one to the position corresponding to the detection component. By filling the gap between the detection component and the edge to be detected with a plug gauge or feeler gauge, the installation position of each mounting seat on the turntable mechanism is judged according to the specifications and quantity of the plug gauge or feeler gauge placed in the gap, thereby correcting the position of each mounting seat, ensuring the consistency of the battery cell position, and improving the processing accuracy of the battery cell.

[0023] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0024] To address the aforementioned technical problems, this embodiment provides a cell fixture with consistency detection capabilities, such as... Figure 1-2As shown, the device includes a mounting base 10 mounted on a turntable mechanism to support the battery cells, and a detection mechanism 40 located on one side of the turntable mechanism. The turntable mechanism has several mounting bases 10. After the battery cells are loaded onto the mounting bases 10, the rotation of the turntable mechanism transports the battery cells to various workstations for processing. A clamping assembly 20 is provided on each mounting base 10. After the battery cells are loaded onto the mounting bases 10, the clamping assembly 20 secures the battery cells, preventing positional displacement of the battery cells during rapid rotation of the turntable mechanism, thereby improving the processing accuracy of the battery cells. Meanwhile, an edge 11 to be tested is formed on the end face or side of the mounting base 10. The testing mechanism 40 includes a testing element 41 and a displacement module 42 that drives the testing element 41 to move toward the edge 11 to be tested. The testing element 41 serves as a reference for testing. Before operation, the turntable mechanism moves the mounting bases 10 one by one to the position corresponding to the testing element 41. By filling the gap between the testing element 41 and the edge 11 to be tested with a plug gauge or feeler gauge, the installation position of each mounting base 10 on the turntable mechanism is judged according to the specifications and quantity of the plug gauge or feeler gauge placed in the gap. This corrects the position of each mounting base 10, ensures the consistency of the cell position, and improves the cell processing accuracy.
[0025] Specifically, the testing mechanism 40 also includes a support base 43, a displacement module 42 mounted on the support base 43, and a testing element 41 connected to the drive end of the displacement module 42. For example, the displacement module 42 can be composed of a cylinder. The displacement module 42 drives the testing element 41 to move horizontally and vertically, allowing the testing element 41 to approach the mounting base 10 on the turntable mechanism. Thus, when calibrating the position of the mounting base 10, the testing element 41 serves as a fixed reference for testing. The turntable mechanism moves each mounting base 10 to the position corresponding to the testing element 41. By filling the gap between the testing element 41 and the edge 11 to be tested with a plug gauge or feeler gauge, the installation position of each mounting base 10 is determined based on the specifications and quantity of the plug gauge or feeler gauge placed in the gap, thereby ensuring the consistency of the battery cell position and improving the subsequent processing accuracy of the battery cells. The edge 11 to be tested can be the bottom surface, side surface, or end surface of the mounting base 10.
[0026] Furthermore, the clamping assembly 20 includes a first driver 22 disposed on the mounting base 10 and a pressure block 21 disposed on the driving end of the first driver 22. The first driver 22 is used to drive the pressure block 21 to press down on the battery cell on the mounting base 10. For example, the first driver 22 can be a cylinder. When the battery cell is loaded onto the mounting base 10, the side of the battery cell with the tabs faces outwards. Then, the first driver 22 drives the pressure block 21 to press down on the surface of the battery cell, thereby fixing the battery cell on the mounting base 10. This prevents the battery cell from shifting position when the turntable mechanism rotates rapidly, thereby improving the processing accuracy and production quality of the battery cell.
[0027] In the above scheme, a tab shaping assembly 30 is also provided on the mounting base 10 above the pressure block 21. The tab shaping assembly 30 is used to press down the tabs on the battery cell. Then, the tab shaping assembly 30 makes the outward-facing tabs of the battery cell bend vertically downward, thereby adjusting the battery cell tabs to a suitable position to accommodate further bending of the tabs, such as subsequent Z-shaped bending of the tabs.
[0028] Specifically, the tab shaping assembly 30 includes a bracket 33 mounted on the mounting base 10, a lifting plate 34 slidably mounted on the bracket 33, and a second driver 32 for moving the lifting plate 34. A shaping block 31 is provided at the end of the lifting plate 34. For example, the second driver 32 can be a cylinder. After the battery cell is placed on the mounting base 10, the shaping block 31 is positioned above the tab. The second driver 32 drives the lifting plate 34 to move up and down, so that when the shaping block 31 descends, it can bend the outward-facing tab vertically downwards, thereby adjusting the battery cell tab to a suitable position and fixing the tab, which can then be further bent.
[0029] Furthermore, a limit switch 35 is provided on the mounting base 10 below the lifting plate 34. The limit switch 35 limits the descent position of the lifting plate 34, thereby preventing excessive descent that could damage the battery cell tabs.
[0030] In the above scheme, the bracket 33 is provided with a guide post and guide sleeve structure 36. The guide post and guide sleeve structure 36 consists of a guide post provided on the bracket 33 and a guide sleeve slidably provided on the guide post. The guide sleeve is connected to the lifting plate 34, and the lifting plate 34 is slidably provided on the bracket 33 through the guide post and guide sleeve structure 36, so that the lifting plate 34 can move smoothly up and down on the bracket 33.
[0031] Furthermore, this embodiment also includes a fixed base 12 mounted on the turntable mechanism. The mounting base 10 is slidably disposed on the fixed base 12, and a third driver 13 connected to the mounting base 10 is disposed on the fixed base 12. The fixed base 12 is fixed on the turntable mechanism, and the mounting base 10 is slidably disposed on the fixed base 12 via a slide rail. The third driver 13 can be a cylinder or a motor screw drive structure, thereby driving the mounting base 10 to move up and down, thereby adjusting the height position of the mounting base 10 to cooperate with the detection mechanism 40 to complete the position calibration.
[0032] On the other hand, this embodiment provides a battery cell tab shaping device, such as Figure 3As shown, the device includes the aforementioned cell fixture with consistency detection and a shaping mechanism 50 disposed on the conveying path of the turntable mechanism. An auxiliary shaping component 60 is disposed on one side of the shaping mechanism 50. The turntable mechanism rotates to convey the cell fixture. After passing through the auxiliary shaping component 60, the cell fixture reaches the shaping mechanism 50, where the electrode tabs are shaped and bent into a preset shape. For example, in the Z-shaped bending process of the electrode tabs, the cell fixture needs to move sequentially to multiple bending and shaping devices for multiple bending. Therefore, this solution uses the auxiliary shaping component 60 to guide the ends of the cell electrode tabs, preventing the ends of the electrode tabs from drooping during transportation and keeping the electrode tabs in a horizontal state.
[0033] Furthermore, the auxiliary shaping component 60 includes a guide block 61, one end of which has an arc-shaped guide surface 62. The drooping electrode tab is then corrected by the arc-shaped guide surface 62. Simultaneously, the arc shape is adapted to the turntable, so that when the turntable mechanism rotates, the electrode tab, under the action of the arc-shaped guide surface 62, completes the adjustment of its end, keeping the electrode tab horizontal before entering the shaping mechanism 50, thereby improving the subsequent bending effect.
[0034] In summary, in one or more embodiments of this application, the solution involves setting multiple mounting seats on a turntable mechanism and a detection mechanism located on one side of the turntable mechanism. After the battery cell is loaded onto the mounting seat, it is fixed by a clamping assembly to prevent the battery cell from shifting position during rapid rotation of the turntable mechanism, thereby improving the processing accuracy of the battery cell. An edge to be inspected is formed on the end face or side of the mounting seat. The detection mechanism includes a detection element and a displacement module that drives the detection element to move towards the edge to be inspected. The detection element serves as a reference for inspection. Before operation, the turntable mechanism moves each mounting seat to the position corresponding to the detection element. By filling the gap between the detection element and the edge to be inspected with plug gauges or feeler gauges, the installation position of each mounting seat on the turntable mechanism is determined based on the specifications and quantity of the plug gauges or feeler gauges placed in the gap. This corrects the position of each mounting seat, ensuring the consistency of the battery cell position and improving the processing accuracy of the battery cell.
[0035] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
