Detailed Implementation

[0026] The formation apparatus and formation system of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0027] Please refer to Figures 1 to 3 The figures shown are schematic diagrams of the formation device, the formation magazine, and the formation system in this invention.

[0028] This invention provides a formation apparatus 100, mainly used for simultaneously forming multiple battery cells, particularly for directly forming multiple battery cells on a formation magazine. Specifically, the formation apparatus 100 mainly includes a carrier plate 10 and a carrier placement mechanism 20, a tab connection mechanism 30, and a drive mechanism 40 disposed on the carrier plate 10. The carrier placement mechanism 20 is used for detachably mounting a carrier for loading battery cells, and the tab connection mechanism 30 is used to connect the tabs of the battery cells. When the carrier is mounted on the carrier placement mechanism 20, the drive mechanism 40 drives the tab connection mechanism 30 to connect the tabs of the battery cells on the carrier. The formation apparatus 100 is also provided with a power charging and discharging device that provides power supply during the formation process. The tab connection mechanism 30 is connected to the power charging and discharging device. When the tab connection mechanism 30 connects to the tabs of the battery cells, the battery cells are formed by the power charging and discharging device.

[0029] The present invention provides a formation magazine 200, which is mainly used to load multiple battery cells to be formed. The formation magazine 200 has a hollow area. When the formation magazine 200 is installed on the carrier placement mechanism 20, the tab connection mechanism 30 connects to the tabs on both sides of the multiple battery cells through the hollow area, thereby realizing the formation of multiple battery cells.

[0030] For further information, please refer to the following: Figure 1 and Figure 3 As shown, the vehicle placement mechanism 20 includes limiting blocks 21, which are used for limiting and fixing the vehicle. The number and distribution of the limiting blocks 21 correspond to the vehicle. For example, there are three limiting blocks 21 distributed at three points, so that the forming magazine 200 is fixed by the three limiting blocks 21. Specifically, the fixing is achieved by opening fixing edges on the limiting blocks 21 that correspond to the shape of the vehicle. For example, if the forming magazine 200 is rectangular, the limiting blocks 21 have right-angled edges that correspond to the shape of the forming magazine 200, thereby strengthening the fixing effect of the limiting blocks 21 on the vehicle. In this application, the distribution of the limiting blocks 21 corresponds to the tab connection mechanism 30, so that the tab connection mechanism 30 can connect the tabs of multiple cells of the vehicle. For example, the vehicle fixed on the limiting blocks 21 is located above the tab connection mechanism 30.

[0031] For further information, please refer to the following: Figure 1 and Figure 3As shown, the vehicle placement mechanism 20 also includes a positioning block 22 that cooperates with the limiting block 21. The positioning block 22 is used for clamping and positioning the vehicle. For example, the limiting block 21 fixes one side of the vehicle, and the positioning block 22 is used to fix the other side of the vehicle. The positioning block 22 has an elastic fixing force on the vehicle, thereby making the vehicle close to the limiting block 21 for fixation, resulting in a good fixing effect. At the same time, it allows the vehicle placement mechanism 20 to be used for vehicles of different sizes. For example, the positioning block 22 is a spring push rod, wherein the spring force of the spring push rod is directed towards the other side of the vehicle, thereby pushing the vehicle towards the limiting block 21 on the other side and achieving elastic clamping and positioning of the vehicle.

[0032] For further information, please refer to the following: Figure 1 and Figure 3 As shown, the electrode connection mechanism 30 includes a plurality of connection components 31 corresponding to the carrier placement mechanism 20, wherein each connection component 31 is used to connect the two electrodes of a plurality of battery cells. The distribution of the plurality of connection components 31 can be set according to the fixed position of the battery cells on the forming magazine 200. For example, the plurality of connection components 31 are evenly arranged in the same direction, or the plurality of connection components 31 are arranged in opposite directions at intervals in the same direction.

[0033] In practical applications, each connecting component 31 mainly includes a fixed connecting unit 311A ​​and an adjustable connecting unit 311B arranged opposite to each other. The fixed connecting unit 311A ​​and the adjustable connecting unit 311B cooperate to connect the two tabs of multiple battery cells respectively. The adjustable connecting unit 311B can slide relative to the fixed connecting unit 311A. In other words, the distance between the adjustable connecting unit 311B and the fixed connecting unit 311A ​​is adjustable. By adjusting the position of the adjustable connecting unit 311B relative to the fixed connecting unit 311A, the connecting component 31 can adapt to connecting battery cells of different sizes, thereby enhancing the versatility of the formation device of the present invention.

[0034] Please refer to the following for further details. Figure 4 and Figure 5The figures shown are one structural schematic diagram and another structural schematic diagram of the adjustable connection unit. Both the fixed connection unit 311A ​​and the adjustable connection unit 311B include a fixed plate 3111 and a movable plate 3112. The fixed plate 3111 is equipped with multiple PCB boards 3113 for connecting the battery cell tabs. The movable plate 3112 is equipped with multiple clamping plates 3114 corresponding to the multiple PCB boards 3113. The PCB boards 3113 and the clamping plates 3114 cooperate to clamp and connect one side of the battery cell tab. The drive mechanism 40 drives the movable plate 3112 to move relative to the fixed plate 3111, thereby controlling the opening and closing between the multiple PCB boards 3113 and the multiple clamping plates 3114, so that the multiple PCB boards and the multiple clamping plates cooperate to clamp the multiple battery cell tabs. Both the PCB board 3113 and the clamping plate 3114 are detachable. For example, the PCB board 3113 and the clamping plate 3114 are respectively installed on the fixed plate 3111 and the movable plate 3112 by screw connection. Alternatively, the PCB board 3113 and the clamping plate 3114 are respectively installed on the fixed plate 3111 and the movable plate 3112 by snap-fit ​​connection. This allows for quick disassembly and installation of the PCB board 3113 and the clamping plate 3114, and the corresponding PCB board 3113 and the clamping plate 3114 can be replaced according to the product model and size, enabling rapid production transition. It is also worth noting that the movable plate 3112 can be connected to the fixed plate 3111 via the guide rail slide 3115. This makes the movement of the movable plate 3112 relative to the fixed plate 3111 smoother, effectively improving the stability of the clamping process of the fixed connection unit 311A ​​and the adjustable connection unit 311B on the battery cell tabs.

[0035] Please refer to the following for further details. Figure 6 As shown, it is Figure 1 The enlarged view of part A shows that the drive mechanism 40 includes a drive element 41 and a connecting plate 42. The drive element 42 drives the movable plate 3112 to move relative to the fixed plate 3111 via the connecting plate 42, thereby enabling the drive mechanism 40 to drive the tab connection mechanism 30 to connect the tabs on both sides of multiple battery cells. In specific applications, one end of the movable plate 3112 is slidably disposed on the connecting plate 42. For example, one end of the movable plate 3112 is provided with a slot, and the connecting plate 42 is simultaneously engaged in the slot of the movable plate 3112 of both the fixed connecting unit 311A ​​and the adjustable connecting unit 311B. Alternatively, one end of the movable plate 3112 is slidably connected to the connecting plate 2 via a guide rail slide. In this way, the connecting plate 42 and the movable plate 3112 are slidably connected, ensuring the effectiveness of the drive mechanism 40 in driving the tab connection mechanism 30, while allowing the adjustable connecting unit 311B to be adjusted in position relative to the drive mechanism 40. In this application, the drive element 41 is a cylinder or an electric push rod.

[0036] For further details, please refer to... Figure 1, Figures 7 to 9 As shown, where Figures 7 to 9 These are schematic diagrams of the linkage adjustment mechanism, including diagram one, schematic diagram two, and... Figure 1 The enlarged view of part B shows that the formation apparatus 100 also includes a linkage adjustment mechanism 50. The linkage adjustment mechanism 50 is mainly used to simultaneously adjust the spacing between the fixed connection unit 311A ​​and the adjustable connection unit 311B of multiple connection components 31, thereby ensuring that the spacing between the fixed connection unit 311A ​​and the adjustable connection unit 311B of each connection component 31 in the formation apparatus 100 remains consistent, thereby improving the reliability of the formation process of the formation apparatus 100.

[0037] In practical applications, the linkage adjustment mechanism 50 mainly includes a spacing adjustment component 51 and a moving component 52. The moving component 52 is slidably disposed on the carrier plate 10, and more specifically, it is slidably disposed on one side of the tab connecting mechanism 30. The spacing adjustment component 51 is connected to the moving component 52. One end of the adjustable connecting unit 311B of multiple connecting components 31 is disposed on the moving component 52. In this way, by adjusting the position of the moving component 52 relative to the carrier plate 10 through the spacing adjustment component 51, the spacing between the fixed connecting unit 311A ​​and the adjustable connecting unit 311B of multiple connecting components 31 can be adjusted simultaneously. Specifically, the spacing adjustment component 51 includes an adjusting fixed base 511 and an adjusting screw 512 disposed on the adjusting fixed base 511. One end of the adjusting screw 512 is rotatably connected to the moving component 52. By rotating the adjusting screw 512, its position relative to the adjusting fixed base 511 can be adjusted, thereby adjusting the position of the moving component 52 relative to the carrier plate 10.

[0038] To accommodate different fixed distributions of the battery cells on the forming magazine 200, the moving component 52 can adjust the adjustable connecting units 311B of the multiple connecting components 31 in either a unidirectional or bidirectional manner. In unidirectional adjustment, the adjustable connecting units 311B of the multiple connecting components 31 move in the same direction as the moving component 52. In bidirectional adjustment, the adjustable connecting units 311B of the multiple connecting components 31 can move along the direction of the moving component 52, in the opposite direction, or in both directions, depending on the different fixed distributions of the battery cells on the forming magazine 200.

[0039] In practical applications, the moving component 52 includes a first adjusting plate 521 and a second adjusting plate 522 slidably arranged side-by-side on the carrier plate 10. The first adjusting plate 521 is provided with a rack 5211, and the second adjusting plate 522 is provided with a gear 5221 that meshes with the rack 5211. The gear 5221 is rotatable relative to the second adjusting plate 522. When adjusting the position of the adjustable connecting unit 311B, the spacing adjusting component 51 adjusts the moving position of the first adjusting plate 521 or the second adjusting plate 522, so that the first adjusting plate 521 and the second adjusting plate 522 slide in opposite directions. The adjustable connecting units 311B of the multiple connecting components 31 are connected to the first adjusting plate 521 and the second adjusting plate 522 according to production requirements, thereby enabling the adjustable connecting units 311B to move in the moving direction of the moving component 52, or in the opposite direction, or in both directions. This makes the formation device 100 more versatile and adaptable to different types and structures of formation magazines 200.

[0040] For further information, please refer to the following: Figure 1 As shown, to ensure the stability of the adjustment process of the linkage adjustment mechanism 50 on the tab connection mechanism 30, the end of the adjustable connection unit 311B away from the moving component 52 is slidably disposed on the carrier plate 10. For example, the end of the adjustable connection unit 311B away from the moving component 52 is slidably disposed on a slide rail. This effectively improves the stability of the adjustable connection unit 311B during movement. In one embodiment, to ensure the consistency of movement of the two ends of the adjustable connection unit 311B, the linkage adjustment mechanism 50 further includes linkage ropes 53 respectively connecting the two ends of the adjustable connection unit 311B. The linkage ropes 53 enable the two ends of the adjustable connection unit 311B to move synchronously, thereby ensuring the stability of the adjustable connection unit 311B during adjustment. In another embodiment, the linkage adjustment mechanism 50 further includes a pulley 54 for controlling the movement path of the linkage rope 53. The linkage rope 53 is guided by the pulley 54, causing the linkage rope 53 to move around the working area of ​​the tab connection mechanism 30, thus avoiding the influence of the linkage rope 53 on the operation of the tab connection mechanism 30.

[0041] Please continue to refer to this. Figures 1 to 3As shown, the present invention also provides a formation system, including the formation apparatus 100 described above and a formation magazine 200 disposed on a carrier placement mechanism 20 for loading multiple battery cells. In specific applications, the formation magazine 200 includes a frame 201 and multiple clamping components 202 disposed on the frame 201, wherein each clamping component 202 is used to clamp multiple battery cells; for example, the clamping component 202 is a gripper. Specifically, the multiple clamping components 202 are detachably mounted on the frame 201, for example, by screw connection or by snap-fit, thereby enabling quick installation and removal of the multiple clamping components 202, facilitating replacement of the multiple clamping components 202, and adapting to different battery cell sizes. To improve the stability of the battery cells on the formation magazine 200, the formation magazine 200 also includes multiple support plates 203 corresponding to multiple clamping components 202. Each support plate 203 supports multiple battery cells. For example, the support plate 203 is provided with limiting grooves corresponding to multiple battery cells, thereby supporting multiple battery cells. At the same time, the support plate 203 is position-adjustable, so that the support plate 203 can meet the support requirements of products of different sizes.

[0042] The operating principle of this invention is as follows: In the initial state, the position of the adjusting screw 512 relative to the adjusting fixed seat 511 is adjusted by rotating the adjusting screw 512, thereby adjusting the distance between the fixed connecting unit 311A ​​and the adjustable connecting unit 311B, so that the formation device 100 adapts to the size of the formed battery cell on the formation magazine 200. The formation magazine 200 is placed on the carrier placement mechanism 20, and the formation magazine 200 is positioned by the cooperation of the limiting block 21 and the positioning block 22. At this time, the battery cell tabs of the formation magazine 200 are all located between a PCB board 3113 and a clamping plate 3114. The driving mechanism 40 drives the moving plate 3112 to move relative to the fixed plate 3111, so that the PCB board 3113 and the clamping plate 3114 cooperate to clamp and connect one side of the battery cell tab. Then, the battery cell is formed by the power supply charging and discharging equipment.

[0043] In summary, the formation apparatus of the present invention is provided with a carrier placement mechanism for placing a carrier for loading battery cells, which allows the formation magazine loaded with the battery cells to be formed to be directly placed on the formation apparatus, and then the battery cells are connected to the electrodes of the battery cells through the electrode connection mechanism to perform the formation process, simplifying the production steps and effectively improving the formation efficiency.
