[0047] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] In related technologies, the tabs of the battery cell need to be welded to the corresponding terminals on the top cover of the cell via connecting tabs to form a battery circuit. During welding, to prevent light leakage and to avoid damage to the cell from flying weld slag and dust, a protective cover is usually pressed onto the connecting tab to shield the welding area. In these technologies, a clamping device is needed to pick up the protective cover from the loading station and place it at the welding point. However, the clamping device in these technologies requires a horizontal transfer mechanism and a vertical drive component to drive the clamping assembly to move horizontally and vertically respectively, making the structure complex. Furthermore, the vertical drive component cannot precisely control the distance the clamping assembly moves vertically, resulting in inaccurate gripping of the protective cover and significantly reducing operational reliability.

[0052] To address the aforementioned issues, as shown in Figures 1 and 2, this embodiment provides a battery cell protective cover clamping device. This device includes a horizontal transfer mechanism 1 and a clamping mechanism 2. The clamping mechanism 2 comprises an installation component 21, a clamping component 22, and an elastic component 23. The elastic component 23 is connected between the installation component 21 and the clamping component 22 and extends vertically (up and down in the figures). The clamping component 22 is used to clamp or release the battery cell protective cover 20. The installation component 21 is connected to the output end of the horizontal transfer mechanism 1. The horizontal transfer mechanism 1 is configured to drive the installation component 21 to move horizontally (left and right in the figures) so that the clamping component 22 clamps the battery cell protective cover 20 and moves it between the loading station and the welding station. The battery cell protective cover clamping device provided in this embodiment enables the clamping component 22 to clamp the battery cell protective cover 20 at the loading station, and under the drive of the horizontal transfer mechanism 1, the clamping component 22 moves the clamped battery cell protective cover 20 to the welding station, ensuring that the battery cell protective cover 20 achieves the welding protection effect for the battery cell at the welding station. Furthermore, the clamping mechanism 2, by setting an elastic component 23 extending vertically between the mounting component 21 and the clamping component 22, allows the clamping component 22 to elastically float relative to the mounting component 21 in the vertical direction, thereby accurately matching the clamping part on the battery cell protective cover 20. This ensures that the clamping component 22 accurately grips the battery cell protective cover 20 at the loading station, eliminating the need for an additional drive component to move the clamping component 22 vertically, resulting in a simple structure and stable and reliable operation.

[0053] Optionally, in this embodiment, the horizontal transplanting mechanism 1 is a motor lead screw module. Since the specific structure and working principle of the motor lead screw module driving the mounting assembly 21 to move horizontally are existing technologies, they will not be described in detail here. Optionally, in this embodiment, the mounting assembly 21 is in the form of a mounting plate.

[0054] Optionally, in this embodiment, as shown in FIG1, the battery cell protective cover clamping device further includes a frame 5, and a horizontal transplanting mechanism 1 is disposed on the frame 5, thereby achieving reliable support and fixation of the horizontal transplanting mechanism 1.

[0055] Optionally, in this embodiment, as shown in Figures 2 to 4, the battery cell protection cover 20 is provided with two opposing and spaced-apart first insertion holes 201. The clamping assembly 22 includes a clamping cylinder 221, a first insertion pin 223, and two clamps 222. The clamping cylinder 221 is connected to the mounting assembly 21 by an elastic component 23. The two clamps 222 are opposing and spaced-apart. The output end of the clamping cylinder 221 is connected to the two clamps 222 in a transmission connection. The clamping cylinder 221 is used to synchronously drive the two clamps 222 to move closer or further away from each other. A first insertion pin 223 is provided on the side of each clamp 222 away from the other clamp 222. The first insertion pin 223 is used to be inserted and fixed with the first insertion hole 201 on the corresponding side. The structural design of the clamping assembly 22 allows it to grip the battery cell protective cover 20 at the loading station. When the clamping assembly 22 needs to grip the battery cell protective cover 20, the gripper cylinder 221 synchronously drives the two grippers 222 to move away from each other, causing the two first insertion pins 223 to insert into the corresponding first insertion holes 201. When the clamping assembly 22 needs to release the battery cell protective cover 20, the gripper cylinder 221 synchronously drives the two grippers 222 to move closer together, causing the two first insertion pins 223 to disengage from the corresponding first insertion holes 201. This structural design of the clamping assembly 22 results in a simple structure and reliable operation.

[0056] It should be noted that each of the two connecting ears on the lower end face of the battery cell protective cover 20 is provided with a through first insertion hole 201. By causing the gripper cylinder 221 to elastically float relative to the mounting assembly 21 in the vertical direction, it can be ensured that when the battery cell protective cover 20 is in the loading position, the gripper 222 elastically abuts against the lower end face of the battery cell protective cover 20, ensuring that the first insertion pin 223 on the gripper 222 is precisely aligned with the first insertion hole 201 on the corresponding side, thereby ensuring that the first insertion pin 223 is accurately inserted into the first insertion hole 201 on the corresponding side.

[0057] Optionally, as shown in Figures 2 and 3, the elastic component 23 includes at least two elastic elements 231. The two elastic elements 231 are spaced apart along the direction of the two grippers 222, each extending vertically and connected between the mounting component 21 and the gripper cylinder 221. By providing at least two elastic elements 231, multiple positions of the gripper cylinder 221 can float vertically relative to the mounting component 21, ensuring that both first insertion pins 223 can be accurately inserted into the corresponding first insertion holes 201. Optionally, the elastic element 231 can be a spring, but is not limited to this; it can also be a sheet spring or a compression spring. Optionally, in this embodiment, the elastic component 23 includes two elastic elements 231. In other embodiments, the specific number of elastic elements 231 can be adjusted according to requirements.

[0058] In this embodiment, as shown in Figures 2 and 3, the gripping mechanism 2 further includes a guide component 24. The guide component 24 includes a guide rail 241 and a slider 242 that are slidably connected. The guide rail 241 extends vertically. One of the guide rail 241 and the slider 242 is disposed on the mounting component 21, and the other of the guide rail 241 and the slider 242 is disposed on the gripper cylinder 221. By providing the guide component 24, guidance is provided for the vertical floating of the gripper cylinder 221 relative to the mounting component 21, ensuring the stability and reliability of the vertical floating of the gripper cylinder 221. Optionally, in this embodiment, the guide rail 241 is disposed on the mounting component 21, and the slider 242 is disposed on the gripper cylinder 221. In other embodiments, the guide rail 241 is disposed on the gripper cylinder 221, and the slider 242 is disposed on the mounting component 21.

[0059] In this embodiment, as shown in FIG2, the clamping mechanism 2 further includes a detection component 25, which is disposed on the mounting component 21. The detection component 25 is used to detect whether there is a battery cell protective cover 20 at the loading station. Specifically, the detection component 25 is communicatively connected to the gripper cylinder 221. When the horizontal transfer mechanism 1 drives the mounting component 21 to move horizontally, so that the clamping component 22 moves to the loading station, the position of the detection component 25 on the mounting component 21 is just enough to detect whether there is a battery cell protective cover 20 at the loading station. When the detection component 25 detects that there is a battery cell protective cover 20 at the loading station, the gripper cylinder 221 receives the signal from the detection component 25 and synchronously drives the two grippers 222 to move away from each other, so that the two first insertion pins 223 are respectively inserted into the first insertion holes 201 on the corresponding sides. Optionally, the detection component 25 is a sensor.

[0060] In this embodiment, as shown in Figures 1, 5, and 6, the battery cell protective cover clamping device further includes a feeding mechanism 3. The feeding mechanism 3 includes a material rack 31 and a top-loading assembly 32. The material rack 31 is used to accommodate the battery cell protective cover 20, and the top-loading assembly 32 is disposed at the bottom of the material rack 31. The top-loading assembly 32 is used to lift the battery cell protective cover 20 in the material rack 31 to the feeding position. By having the top-loading assembly 32 lift the battery cell protective cover 20 in the material rack 31 to the feeding position, it is easier for the clamping assembly 22 to clamp the battery cell protective cover 20 at the feeding position. It should be noted that in this embodiment, the top feeding component 32 is communicatively connected to the detection component 25. When the clamping component 22 moves to the feeding station and the detection component 25 detects that there is no cell protection cover 20 at the feeding station, the top feeding component 32 can lift the cell protection cover 20 in the material rack 31 according to the detection signal of the detection component 25. When the detection component 25 detects the cell protection cover 20, the top feeding component 32 stops driving.

[0061] In this embodiment, as shown in Figure 5, the top-loading assembly 32 includes a lifting drive 321 and a lifting plate 322. The lifting plate 322 is connected to the output end of the lifting drive 321. The lifting drive 321 drives the lifting plate 322 to move vertically, thereby lifting the battery cell protective cover 20 inside the material rack 31 and ensuring that the battery cell protective cover 20 inside the material rack 31 is lifted to the loading station. It should be noted that in this embodiment, the lifting drive 321 is communicatively connected to the detection assembly 25. Optionally, in this embodiment, the lifting drive 321 is a servo electric cylinder, which has the advantages of high precision, low maintenance cost, and environmental protection and energy saving.

[0062] In this embodiment, as shown in FIG5, the top material assembly 32 further includes a top material mounting plate 323, which is disposed at the bottom of the material rack 31. The lifting plate 322 is slidably connected to the top material mounting plate 323 in the vertical direction, and the lifting drive component 321 is disposed on the top material mounting plate 323.

[0063] Optionally, in this embodiment, as shown in FIG6, the material rack 31 includes a material rack body 311 and a support plate 312. The support plate 312 is slidably connected to the material rack body 311 in the vertical direction. The support plate 312 and the material rack body 311 together enclose a receiving space 313 for accommodating the battery cell protective cover 20, and the support plate 312 supports the battery cell protective cover 20 in the receiving space 313. The support plate 312 abuts against the lifting plate 322. With the above arrangement, when the lifting drive member 321 drives the lifting plate 322 to move upward, the lifting plate 322 pushes the support plate 312 to move upward relative to the material rack body 311, so that the support plate 312 supports the battery cell protective cover 20 and rises to the loading position. It should be noted that in this embodiment, the top mounting plate 323 is connected to the bottom of the material rack body 311. Optionally, in this embodiment, the opposite sides of the support plate 312 are slidably connected to the corresponding sides of the sliding groove of the material rack body 311 in the vertical direction. Optionally, both sides of the battery cell protective cover 20 can slide vertically relative to the corresponding side of the material rack body 311 through the groove, thereby ensuring that the battery cell protective cover 20 supported by the bearing plate 312 moves vertically relative to the material rack body 311 within the accommodating space 313.

[0064] In this embodiment, as shown in Figure 1, the battery cell protective cover clamping device further includes a docking mechanism 4. The docking mechanism 4 includes a lifting drive assembly 41 and a docking assembly 42. The docking assembly 42 is connected to the output end of the lifting drive assembly 41. The lifting drive assembly 41 drives the docking assembly 42 to move vertically, and the docking assembly 42 clamps and fixes the battery cell protective cover 20 transferred to the welding station by the clamping assembly 22. It should be noted that when the clamping assembly 22 clamps the battery cell protective cover 20 and moves it to the welding station under the drive of the horizontal transfer mechanism 1, the lifting drive assembly 41 drives the docking assembly 42 to move downward, so that the docking assembly 42 clamps and fixes the battery cell protective cover 20 at the welding station. After the docking assembly 42 clamps and fixes the battery cell protective cover 20, the clamping assembly 22 releases the battery cell protective cover 20, and the clamping assembly 22 moves and resets to the loading station under the drive of the horizontal transfer mechanism 1. Optionally, in this embodiment, the lifting drive assembly 41 is a servo electric cylinder, which has the advantages of high precision, low maintenance cost, and environmental friendliness and energy saving. It should be noted that in this embodiment, the lifting drive assembly 41 is mounted on the frame 5.

[0065] Optionally, in this embodiment, as shown in Figures 4, 7, and 8, the battery cell protection cover 20 has second insertion holes 202 on both opposite sides. The docking assembly 42 includes a docking mounting plate 421, a second insertion pin 423, and two docking drive members 422. The docking mounting plate 421 is connected to the output end of the lifting drive assembly 41. The two docking drive members 422 are disposed opposite to each other and spaced apart on the docking mounting plate 421. Each docking drive member 422 has a second insertion pin 423 at its output end. The docking drive member 422 is used to drive the second insertion pin 423 to move so that the second insertion pin 423 is inserted and fixed in the second insertion hole 202 on the corresponding side. When the docking assembly 42 needs to clamp and fix the battery cell protective cover 20 at the welding station, the two docking drive members 422 are driven synchronously, causing the two second insertion pins 423 to move closer to each other and insert into the corresponding second insertion holes 202. When the docking assembly 42 needs to release the battery cell protective cover 20, the two docking drive members 422 are driven synchronously, causing the two second insertion pins 423 to move away from each other and disengage from the corresponding second insertion holes 202. Optionally, in this embodiment, the docking drive member 422 is a drive cylinder.

[0066] Optionally, in this embodiment, as shown in Figures 4, 7, and 8, a positioning pin 203 is provided on the upper end face of the battery cell protective cover 20, and a positioning pin hole 4211 is provided on the bottom of the docking mounting plate 421. The positioning pin hole 4211 is inserted into the positioning pin 203. This arrangement ensures that when the lifting drive assembly 41 drives the docking assembly 42 to descend and move to the welding station, the positioning pin hole 4211 on the bottom of the docking mounting plate 421 precisely engages with the positioning pin 203 on the battery cell protective cover 20, achieving positioning and engagement of the battery cell protective cover 20. This ensures that the docking assembly 42 can accurately clamp and fix the battery cell protective cover 20 at the welding station.

[0067] To facilitate understanding of the battery cell protective cover clamping device disclosed in this embodiment, the specific working process of the battery cell protective cover clamping device will now be described with reference to Figures 1 to 8:

[0068] First, the lifting drive 321 drives the lifting plate 322 to move upward, so that the lifting plate 322 lifts the cell protection cover 20 in the material rack 31, thereby lifting the cell protection cover 20 in the material rack 31 to the loading station; then, the horizontal transfer mechanism 1 drives the mounting assembly 21 to move horizontally, so that the clamping assembly 22 moves to the loading station and clamps the cell protection cover 20 at the loading station; then the horizontal transfer mechanism 1 drives the mounting assembly 21 to move horizontally, so that the clamping assembly 22 clamps the cell protection cover 20 and moves it to the welding station; then the lifting drive assembly 41 drives the docking assembly 42 to move vertically... The assembly moves downwards in a straight line until the positioning pin hole 4211 at the bottom of the mounting plate 421 is inserted into the positioning pin 203 on the cell protection cover 20. Then, the two docking drive components 422 are driven synchronously, so that the two second insertion pins 423 approach each other and are inserted into the corresponding second insertion holes 202, so that the docking assembly 42 clamps and fixes the cell protection cover 20 at the welding station. At this time, the clamping assembly 22 releases the cell protection cover 20 at the welding station, and the horizontal transfer mechanism 1 drives the mounting assembly 21 to move horizontally, so that the clamping assembly 22 moves and resets to the loading station.
