Description

Technical Field

[0002] A battery cell is the core structure of a lithium-ion battery. It refers to a single electrochemical cell containing positive and negative electrodes. It is not used directly; the cell and the protection circuit board together form a battery that can be used directly. The cell includes the cell body, which is generally a block or columnar structure. It contains multiple layers of positive and negative electrodes, which are filled with electrolyte to form the cell body. One end wall of the cell body has flexible sheet-like positive and negative electrode plates that extend outwards for connection to the circuit to provide power.

[0003] In the manufacturing process of battery cells, the manufactured cells still require subsequent processing steps, such as capping the tabs. The cap needs to pass through the horizontally extending tab from the outside and be fastened to the side wall of the cell. Before capping, the tabs need to be shaped and cut to ensure consistent surface flatness and length. Based on these manufacturing process requirements, a battery cell platform needs to be designed to automate the feeding, shaping, tab cutting, capping, tab bending pre-pressing, and unloading of the cells. In completing these processes, the first step is to solve the problem of supporting and fixing the battery cell. Simultaneously, the surface flatness of the tabs in a suspended state needs to be addressed to ensure the accuracy of subsequent cutting and capping processes, avoiding cutting errors and misalignment between the tabs and the capping holes during the capping process, which could lead to bending deformation.

[0015] The beneficial effects of this invention are as follows: This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a battery cell tab shaping and cutting platform, along with its fixture and drive mechanism. This platform achieves surface shaping of the tab in a suspended state, auxiliary pressing of the tab during capping, and synchronous bending and pre-pressing of the positive and negative tabs, while ensuring the positional accuracy and flatness of the battery cell. It also improves the battery cell manufacturing efficiency, effectively enhances the positional accuracy and surface flatness of the battery cell and tab, and increases the yield rate.

[0016] This invention aims to provide a battery cell tab shaping and cutting platform, along with its fixtures and drive mechanism, for automated battery cell manufacturing in the field of new energy batteries. Belonging to the category of automated battery cell manufacturing equipment, its function is to provide an automated battery cell and tab manufacturing platform. Through a rotating turntable, it achieves automatic connection and switching between various processes, reducing the time spent on process transfers and improving manufacturing efficiency. Specifically, the invention uses a circular turntable as the process switching carrier. Multiple fixtures are spaced along the circumference of the turntable to support and clamp battery cell components. Around the turntable, a feeding mechanism, a tab shaping mechanism, a second CCD component, a tab cutting mechanism, and a unloading mechanism are spaced. When the turntable rotates, the fixtures sequentially switch the battery cell components to the aforementioned mechanisms or components to complete processes such as feeding, tab shaping, CCD detection and imaging, tab cutting, and unloading. Simultaneously, a tab capping mechanism can be provided at the second CCD component for capping the tabs after shaping and imaging / inspection.

[0017] To address the issues of cell positioning and flatness during the manufacturing process, this invention designs a fixture. The fixture uses a fixture base as its support structure, mounted on a turntable. A cell holder is horizontally positioned on the fixture base to hold the cells, and the cells are secured using vacuum negative pressure adsorption to prevent positional shifts during turntable rotation. Since the tabs are located on one side wall of the cell and extend horizontally outwards, the tabs of the cells placed on the cell holders are suspended on the fixture, facilitating subsequent cutting and capping processes. To ensure tab flatness, the fixture of this invention includes a cell-pressing assembly. This assembly presses the side of the cell connected to the tabs via line contact, preventing tension during tab shaping or cutting from causing positional shifts and affecting tab positioning accuracy. The cell-pressing assembly uses a drive motor located below the fixture base as its power output structure. The drive motor drives a strip-shaped cell pressing block horizontally positioned at its top via a drive shaft to move up and down, thus ensuring the flatness of the tabs. The battery cell is pressed down from above, while the drive shaft rotates the battery cell pressing block in the horizontal plane to avoid motion interference when removing or discharging the battery cell. When the battery cell needs to be removed or discharged from the battery cell holder, the battery cell pressing block rotates to the outside of the battery cell holder. After the battery cell is placed, the battery cell pressing block rotates to the top of the side of the battery cell and presses the battery cell down. Furthermore, the end of the battery cell pressing block is also equipped with a guide wheel. During the downward pressing of the battery cell, the guide wheel slides in the guide groove of the guide support. Through the cooperation of the guide groove and the guide wheel, the battery cell pressing block is guided and limited, while ensuring that the battery cell pressing block and the side of the battery cell remain parallel. At the same time, it can also play a limit limiting role to prevent the battery cell pressing block from pressing the battery cell too much and causing pressure loss.

[0018] During the capping process, it is necessary to ensure the flatness of the suspended electrode tab to avoid problems such as the electrode tab failing to be inserted into the cap hole due to misalignment, or deformation and bending during insertion, leading to capping failure. To ensure the flatness of the electrode tab, the fixture of this invention also includes an electrode tab pressing assembly. The electrode tab pressing assembly is located below the fixture base. Its electrode tab pressing plate extends through a through groove in the fixture base to the top of the battery cell electrode tab and provides a bearing plane from above to allow the electrode tab to approach. The external electrode tab capping mechanism supports the bottom surface of the electrode tab from below, thereby supporting and limiting the electrode tab from both the top and bottom surfaces to ensure that the electrode tab is properly capped. The flatness of the tabs during the process is ensured. Furthermore, as the capping action progresses, the tab clamping plate gradually slides towards the side wall of the battery cell, allowing the tab to be gradually inserted into the outer cap hole. Simultaneously, the tab clamping plate moves inward during insertion, further inserting the exposed tab into the cap hole. This changing state of pressure and restraint on the tab surface ensures smooth insertion into the cap hole while maintaining continuous restraint on tabs not yet inserted. This significantly reduces the risk of bending deformation of the flexible tab during insertion, thus ensuring a high yield rate for the tab caps. The power for the tab clamping plate to move vertically towards the tab and horizontally during insertion is provided by the tab clamping drive assembly. Specifically, the electrode tab assembly is connected to the bottom of the fixture base via a support base. A first slide block is slidably mounted horizontally on the side wall of the support base. The first slide block is an L-shaped seat, with one side wall connected to the side wall of the support base and a second slide block slidably mounted vertically on the other vertical side wall. Simultaneously, a second drive wheel and a first drive wheel are rotatably connected to the bottoms of the first and second slide blocks, respectively. The electrode tab drive assembly drives the first slide block to move up and down by outputting vertical power to the second drive wheel, and drives the second slide block to move linearly horizontally by outputting horizontal power to the first drive wheel. The top of the second slide block is a Z-shaped rod structure that passes through a through slot. Extending upwards to above the tab, the tab clamp is set on the rod structure of the second slide along the side of the cell. The tab clamp has a corresponding piece near the positive and negative tabs. An L-shaped groove is formed between the piece and the rod of the tab clamp. Before the cap is put on, the bottom of the piece contacts the outer end of the tab from above. As the cap is put on, the piece slides inward on the tab surface until the L-shaped groove is fastened to the side wall of the cell, and the cap is completed. During the capping process, the piece always maintains a state of line contact with the tab surface and slides inward gradually as the cap is put on. This not only limits the tab from above and ensures the flatness of the tab surface during the capping process, but also stretches and flattens the tab during the movement of the tab surface.Furthermore, a first pressure sensor and a second pressure sensor are respectively provided on the first slide and the second slide. The first pressure sensor and the second pressure sensor realize elastic contact with the first slide and the second slide, and at the same time can detect the pressure of the tab pressing plate in real time during the movement of the vertical and horizontal directions, so as to control the movement of the tab pressing plate in real time and accurately to cooperate with the capping action of the capping mechanism. Furthermore, as the power drive structure for the tab pressing plate, the tab pressing drive assembly of the present invention uses a support as the bearing structure. A horizontal push motor is provided on the side wall of the support in the horizontal direction. The power output of the horizontal push motor drives the horizontal slide to drive the horizontal push block to move horizontally. The horizontal push block drives the second transmission wheel to drive the first slide to move horizontally. At the same time, the vertical movement motor provided on the horizontal slide drives the vertical slide to drive the vertical push block to move up and down in the vertical direction. The vertical push block drives the first transmission wheel to drive the second slide to move up and down. The interconnection between the horizontal slide and the vertical slide cooperates with the interconnection between the first slide and the second slide to realize the synchronous linkage drive of the tab pressing plate in the vertical and horizontal directions.

[0060] Furthermore, this invention addresses the deficiencies and shortcomings of existing technologies by independently developing and designing a battery cell tab shaping and cutting platform, along with its fixtures and drive mechanism. This platform ensures the positional accuracy and flatness of the battery cell while simultaneously shaping the surface of the tabs in a suspended state, assisting in pressing the tabs during capping, and synchronously bending and pre-pressing the positive and negative tabs. This improves battery cell manufacturing efficiency while effectively enhancing the positional accuracy and surface flatness of the battery cell and tabs, thereby increasing the yield rate. This invention aims to provide a battery cell tab shaping and cutting platform, along with its fixtures and drive mechanism, for use in the automated manufacturing of battery cells in the new energy battery field. Belonging to the category of automated battery cell manufacturing equipment, its function is to provide an automated battery cell and tab manufacturing platform.

Around the turntable, there are a feeding mechanism, a tab shaping mechanism, a second CCD component, a tab cutting mechanism, and a unloading mechanism. When the turntable rotates, the fixtures switch the battery cell components one by one to the above-mentioned mechanisms or components to complete the processes of feeding, tab shaping, CCD detection and imaging, tab cutting, and unloading. At the same time, a tab capping mechanism can also be set at the second CCD component to cap the tabs after shaping and imaging and detection. Example 2

[0061] like Figures 9 to 12 As shown in the figure, as an embodiment of the present invention, the support assembly of the present invention includes a fixture base 211, a battery cell holder 212, and a guide support 213. The fixture base 211 is horizontally disposed on the turntable 11. The battery cell holder 212 is horizontally disposed on the fixture base 211, and the surface of the battery cell holder 212 is provided with at least two vacuum suction holes for adsorbing and fixing the battery cell 01 placed thereon. The fixture base 211 has a through groove B that runs vertically through it, and one end of the through groove B extends to the side of the fixture base 211 to form an open opening. The through groove B is located on one side of the battery cell holder 212. The guide support 213 is disposed on the fixture base 211 and protrudes upward. The guide support 213 has a guide groove C.

[0062] The piezoelectric cell assembly includes a drive motor 214, a drive shaft 215, a cell pressing block 216, and a guide wheel 217. The drive motor 214 is located at the bottom of the fixture base 211, and its output end extends upward through the fixture base 211.

The cell pressing block 216 is located on the drive shaft 215. The guide wheel 217 is located at the end of the cell pressing block 216. When removing and discharging cell 01, the cell pressing block 216 rotates to the outside of the cell base 212. After the cell 01 is placed, the cell pressing block 216 rotates to the top of the cell 01, presses the cell 01 along the side of the cell 01, and slides in the guide groove C through the guide wheel 217 for guidance and limiting.

[0063] like Figures 13 to 15 As shown in the figure, as an embodiment of the present invention, the pressure tab assembly 218 of the present invention includes a support base 2181, a first slide 2182, a first pressure sensor 2183, a second slide 2184, a second pressure sensor 2185, a tab pressing plate 2186, a first transmission wheel 2187, and a second transmission wheel 2188. The support base 2181 is connected to the bottom of the fixture base 211. A slide rail is provided on the side wall of the support base 2181, and an outwardly extending support is provided at the bottom of the side wall of the support base 2181. The first slide 2182 is slidably connected to the slide rail on the side wall of the support base 2181. The first pressure sensor 2183 is disposed on the first slide 2182, and its output end faces the support, so that it can be adjusted according to the pressure of the first slide 2184. When the first slide 2182 moves downward, it abuts against the support of the support 2181, and senses the reaction force transmitted upward by the support in real time; the second slide 2184 is slidably connected to the side wall of the first slide 2182, and the second pressure sensor 2185 is set on the second slide 2184 along the movement direction of the second slide 2184 and abuts against the protrusion set on the first slide 2182, so as to sense the force when the second slide 2184 slides in real time; the electrode tab 2186 is set on the second slide 2184 and extends above the electrode tab along the side direction of the cell 01; the first transmission wheel 2187 is rotatably set on the first slide 2182; the second transmission wheel 2188 is rotatably set on the second slide 2184.

[0064] like Figures 7 to 8As shown in the figure, as an embodiment of the present invention, the electrode tab drive assembly 22 includes a support 221, a horizontal push motor 222, a horizontal slide block 223, a horizontal push block 224, a vertical push motor 225, a vertical slide block 226, a vertical push block 227, and a sensor 228. The support 221 is disposed below the electrode tab assembly 218; the horizontal push motor 222 is horizontally disposed at one end of the support 221, and its output shaft extends horizontally; the horizontal slide block 223 is slidably connected to the side wall of the support 221 in the horizontal direction, and is connected to the horizontal push motor 225. The output end of the motor 222 is connected; the horizontal push block 224 is located on the top of the horizontal slide block 223 and protrudes upward, for horizontally pushing the second transmission wheel 2188; the vertical motor 225 is located at the bottom of the horizontal slide block 223 and its output end extends upward; the vertical slide block 226 is slidably connected to the side wall of the horizontal slide block 223 in the vertical direction and is connected to the output end of the vertical motor 225; the vertical push block 227 is located on the top of the vertical slide block 226 and extends horizontally outward, for vertically pushing the first transmission wheel 2187.

[0065] Furthermore, to address the issues of cell position and flatness during the manufacturing process, this invention designs a fixture 21. The fixture 21 uses a fixture base 211 as a support structure and is mounted on a turntable 11. A cell base 212 is horizontally mounted on the fixture base 211 for placing the cell 01. The cell 01 is fixed by vacuum negative pressure adsorption to prevent the cell position from shifting during the rotation of the turntable 11. Since the tabs are located on one side wall of the battery cell 01 and extend horizontally outward, the battery cell and its tabs placed on the battery cell holder 212 are suspended on the fixture 21 to facilitate subsequent cutting and capping processes. To ensure the flatness of the tabs, the fixture 21 of this invention is specifically designed with a battery cell piezoelectric assembly. The function of the piezoelectric assembly is to press the side of the battery cell connected to the tabs in a line contact manner, so as to avoid the tension generated during the tab shaping or cutting process causing the battery cell to shift position, thereby affecting the positional accuracy of the tabs. The piezoelectric assembly uses a drive motor 214 located below the fixture holder 211 as the power output structure. The drive motor 214 drives the strip-shaped battery cell pressing block 216, which is horizontally set on its top, to move up and down through the drive shaft 215, so as to press the battery cell 01 from above. Simultaneously, the drive shaft 215 drives the cell pressing block 216 to rotate in the horizontal plane to avoid motion interference when removing and discharging the cell. When it is necessary to remove and discharge the cell from the cell holder 212, the cell pressing block 216 rotates to the outside of the cell holder 212. After the cell is placed, the cell pressing block 216 rotates to the side above the cell and presses the cell downward. Furthermore, the end of the cell pressing block 216 is also provided with a guide wheel 217. During the downward pressing of the cell, the guide wheel slides in the guide groove C of the guide support 213. Through the cooperation of the guide groove C and the guide wheel 217, the cell pressing block 216 is guided and limited, while ensuring that the cell pressing block 216 and the side of the cell remain parallel. At the same time, it can also play a limit limiting role to avoid the cell pressing block 216 pressing the cell too much and causing pressure loss.

[0066] Furthermore, during the capping process, the flatness of the suspended electrode tab needs to be ensured to avoid problems such as the electrode tab failing to be inserted into the cap hole due to misalignment, or deformation and bending during insertion, leading to capping failure. To ensure the flatness of the electrode tab, the fixture 21 of this invention also includes an electrode tab pressing assembly 218. The electrode tab pressing assembly 218 is disposed below the fixture base 211. Its electrode tab pressing plate 2186 extends through the through groove B opened on the fixture base 211 to the top of the battery cell electrode tab and provides a bearing plane from above to allow the electrode tab to approach. The external electrode tab capping mechanism supports the bottom surface of the electrode tab from below, thereby supporting and limiting the electrode tab from both the top and bottom surfaces. The flatness of the tab is ensured during the capping process. Furthermore, as the capping action progresses, the tab clamping plate 2186 gradually slides towards the side wall of the battery cell, allowing the tab to gradually insert into the cap hole of the outer tab cap 02. During insertion, the tab clamping plate moves inwards simultaneously, ensuring the exposed tab is gradually inserted into the cap hole. This changing state of pressure and limiting on the tab surface ensures smooth insertion into the cap hole while maintaining continuous limiting of the tab not inserted into the cap hole. This greatly avoids bending deformation of the flexible tab during insertion, preventing insertion failure and ensuring a high yield rate for the tab caps. The power for the tab clamping plate 2186 to move vertically towards the tab and horizontally during insertion is provided by the tab clamping drive assembly 22.Specifically, the pressure tab assembly 218 is connected to the bottom of the fixture base via a support base 2181. A first slide block 2182 is slidably mounted on the side wall of the support base 2181 in the horizontal direction. The first slide block 2182 is an L-shaped seat, with one side wall connected to the side wall of the support base 2181, and a second slide block 2184 slidably mounted on the other vertical side wall in the vertical direction. Simultaneously, a second transmission wheel 2188 and a first transmission wheel 2187 are rotatably connected to the bottoms of the first slide block 2182 and the second slide block 2184, respectively. The pressure tab drive assembly 22 outputs vertical power to the second transmission wheel 2188, thereby driving the first slide block 2182 to move up and down. The pressure tab drive assembly 22 outputs horizontal power to the first transmission wheel 2187, thereby driving the second slide block 2184 to move linearly in the horizontal direction. The top of the second slide block 2184 is a Z-shaped rod structure that extends upward through the through slot B to the top of the electrode tab. The electrode tab pressing plate 2186 is set on the rod structure of the second slide block 2184 along the side of the battery cell. The electrode tab pressing plate 2186 has a corresponding piece near the positive and negative electrode tabs. An L-shaped groove is formed between the piece and the rod of the electrode tab pressing plate 2186. Before the cap is put on, the bottom of the piece extends from the outer end of the electrode tab through the line contact. As the cap is put on, the piece slides inward on the surface of the electrode tab until the L-shaped groove is fastened to the side wall of the battery cell, and the cap is completed. During the capping process, the piece always maintains a line contact with the surface of the electrode tab and slides inward gradually as the cap is put on. This not only limits the electrode tab from above and ensures the flatness of the surface during the capping process, but also stretches and flattens the electrode tab during the movement of the electrode tab surface. Furthermore, the first slide 2182 and the second slide 2184 are respectively provided with a first pressure sensor 2183 and a second pressure sensor 2185. The first pressure sensor 2183 and the second pressure sensor 2185 realize elastic contact with the first slide 2182 and the second slide 2184, and can also detect the pressure of the tab plate in real time during the movement of the tab plate in the vertical and horizontal directions, so as to control the movement of the tab plate in real time and accurately to cooperate with the capping action of the capping mechanism.Furthermore, as the power drive structure for the tab pressing plate 2186, the tab pressing drive assembly 22 of the present invention uses a support 221 as a bearing structure. A horizontal push motor 222 is arranged on the side wall of the support 221 in the horizontal direction. The power output of the horizontal push motor 222 drives the horizontal sliding block 224 to move horizontally through the horizontal sliding block 224. The horizontal pushing block 224 pushes the second transmission wheel 2188 to drive the first sliding block 2182 to move horizontally. At the same time, the vertical moving motor 225 arranged on the horizontal sliding block 223 drives the vertical sliding block 226 to move the vertical pushing block 227 up and down in the vertical direction. The vertical pushing block 227 pushes the first transmission wheel 2187 to move the second sliding block 2184 up and down. The interconnection between the horizontal sliding block 223 and the vertical sliding block 226 cooperates with the interconnection between the first sliding block 2182 and the second sliding block 2184 to realize the synchronous linkage drive of the tab pressing plate 2186 in the vertical and horizontal directions.
