[0031] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the utility model will be further explained below by combining the drawings and through specific embodiments. It can be understood that the specific embodiments described herein are only used for explaining the utility model, not limiting the utility model.

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.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," and "left," 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.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, the top cover assembly 100 generally includes a cover plate 10, two terminals 20 mounted on the cover plate 10, and an explosion-proof valve 30. The two terminals 20 are the positive terminal and the negative terminal, respectively, and the explosion-proof valve 30 is located between the two terminals 20. Before assembling the top cover assembly 100 with the battery casing, it needs to be assembled into a loose assembly state, and then transferred to the welding station for welding assembly operations, finally completing the fabrication of the top cover assembly 100.

[0037] After multiple components are assembled into a loose top cover assembly 100, they are picked up and transferred to the next welding station by manual or mechanical means. Manual transfer is costly and inefficient; while the existing mechanical picking and transfer method is prone to the risk of material scattering or falling during the picking process of the loose top cover assembly 100 components, mainly the cover plate 10 and the pole post 20, which reduces the picking efficiency.

[0038] To solve the above problems, such as Figures 1 to 3As shown, this embodiment also proposes a clamp for a top cover assembly. The clamp includes a support plate 1, a pre-tightening component 2, and a clamping component. The support plate 1 can move to a clamping station, which is used to support the top cover assembly 100. One end of the pre-tightening component 2 is disposed on the support plate 1. When the support plate 1 moves to the clamping station, the other end of the pre-tightening component 2 can elastically press against the top cover assembly 100 located at the clamping station. The clamping component is disposed on the support plate 1 and can clamp the pressed top cover assembly 100. When the support plate 1 moves to the clamping station, the pre-tightening component 2 presses against the top cover assembly 100 to apply a pre-tightening force to the top cover assembly 100, thereby achieving pre-positioning of the top cover assembly 100 before being clamped. This ensures that the clamping component accurately clamps the top cover assembly 100, preventing the top cover assembly 100 from scattering or falling during the clamping process, and improving the clamping efficiency of the loose top cover assembly 100.

[0039] In this embodiment, the clamping device of the top cover assembly further includes a transfer component. The transfer component drives the support plate 1 to move in the vertical and / or horizontal direction, so that the support plate 1 moves to or away from the clamping station. The vertical direction mentioned above refers to the up-down direction in the figure, and the horizontal direction is perpendicular to the vertical direction. Specifically, the transfer component in this embodiment includes a lifting drive component. The output end of the lifting drive component is connected to the support plate 1 to drive the support plate 1 to move up and down in the vertical direction, so that the support plate 1 descends to the clamping station or rises and leaves the clamping station. In other embodiments, the transfer component may also include a translation drive component. The output end of the translation drive component is connected to the lifting drive component, so that the lifting drive component drives the support plate 1 to move in the horizontal direction. Both the lifting drive component and the translation drive component can be driving components such as cylinders, and are not specifically limited here.

[0040] like Figure 2 and Figure 3 As shown, the pre-tightening assembly 2 includes a guide post, a pressure tube 21, and an elastic element (not shown in the figure). One end of the guide post is mounted on the support plate 1. The other end of the guide post has the pressure tube 21 slidably mounted along the axial direction (vertical direction in the figure). A pressure head 22 is mounted on the end of the pressure tube 21 away from the support plate 1. Both ends of the elastic element abut or connect with the support plate 1 and the pressure tube 21, respectively. The elastic element drives the pressure head 22 to elastically press against the cover plate 10 of the top cover assembly 100. Through the sliding engagement between the pressure tube 21 and the guide post, the pressure tube 21 drives the pressure head 22 to reciprocate along the axial direction of the guide post. When the support plate 1 moves to the clamping position, the elastic element is compressed and applies an elastic restoring force to the pressure head 22, thereby causing the pressure head 22 to elastically press against the cover plate 10, achieving the pre-positioning of the cover plate 10. In this embodiment, the elastic element is a spring, which is sleeved on the pressure tube 21. The end of the pressure tube 21 where the pressure head 22 is mounted has a flange, and the spring is compressed and installed between the flange and the support plate 1.

[0041] Furthermore, the pressure head 22 is an elastic head. The pressure head 22 can be made of rubber or other elastic materials, so that the pressure head 22 has a certain amount of elastic deformation, avoiding damage or scratches to the cover plate 10.

[0042] It should be noted that the lower side of the support plate 1 in this embodiment is evenly distributed with multiple guide posts, so that multiple pressure heads 22 can press against the cover plate 10 together and evenly, ensuring that the cover plate 10 is evenly stressed and preventing the cover plate 10 from tilting or shifting.

[0043] like Figure 2 and Figure 3 As shown, the pre-tightening assembly 2 also includes a positioning component disposed on the support plate 1. When the pressure head 22 elastically presses against the cover plate 10, the positioning component adsorbs the pole post 20 of the top cover assembly 100 to lock the relative position of the pole post 20 and the cover plate 10. By adsorbing the pole post 20 onto the cover plate 10, the positioning component prevents the pole post 20 from shifting from the cover plate 10, thus avoiding material spillage or falling, and improving the clamping efficiency of the loose top cover assembly 100.

[0044] Specifically, the positioning component includes a vacuum generator and suction cups 23. The suction cups 23 are mounted on the support plate 1. The vacuum generator is connected to at least two suction cups 23, and each suction cup 23 adsorbs a corresponding electrode post 20. In this embodiment, there are two suction cups 23, which are spaced apart along the left-right direction on the lower side of the support plate 1. Each suction cup 23 can adsorb a corresponding electrode post 20 via vacuum. In other embodiments, there may be one or more suction cups 23, as long as the number of suction cups 23 and electrode posts 20 are the same and they adsorb one-to-one.

[0045] like Figure 3 As shown, one end of the suction cup 23 is mounted on the support plate 1 and communicates with the vacuum generator, while the other end of the suction cup 23, which has an adsorption port, can elastically press against the corresponding electrode post 20. In this embodiment, the suction cup 23 is generally conical, with the small end of the suction cup 23 mounted on the support plate 1 and communicating with the vacuum generator, and the large end of the suction cup 23 having an adsorption port. The suction cup 23 is made of an elastic material (e.g., rubber), allowing it to elastically compress and deform along its axial direction, thereby elastically pressing against the corresponding electrode post 20, avoiding hard contact with the electrode post 20, and improving the protection of the electrode post 20.

[0046] In this embodiment, the clamping assembly includes a drive member 3 and at least two opposing clamping plates 4, with the drive member 3 being pulsatorically connected to the at least two clamping plates 4. Before the support plate 1 moves to the clamping station, the drive member 3 drives the at least two clamping plates 4 to move away from the support plate 1, thereby opening the clamping plates 4. When the support plate 1 moves to the clamping station, the drive member 3 drives the at least two clamping plates 4 to move towards the support plate 1, thereby closing the clamping plates 4 and clamping the edge of the cover plate 10 of the top cover assembly 100. When the drive member 3 drives the at least two clamping plates 4 to open, it facilitates the clamping plates 4 to avoid or release the cover plate 10; when the drive member 3 drives the at least two clamping plates 4 to close, it causes the at least two clamping plates 4 to clamp the cover plate 10 for transfer of the top cover assembly 100.

[0047] like Figure 2 and Figure 3 As shown, there are three clamping assemblies. Each clamping assembly has two driving members 3 and two clamping plates 4. Each driving member 3 drives one clamping plate 4 to move in a direction away from or towards the support plate 1. In the first clamping assembly, the two driving members 3 are respectively installed at the left and right ends of the upper side of the support plate 1 to avoid occupying the lower side space of the support plate 1, thus optimizing the structural layout of the clamping mechanism of the top cover assembly and making the clamping mechanism of the top cover assembly more compact. The two clamping plates 4 are located on the left and right sides of the support plate 1, respectively. The remaining two clamping assemblies are installed at intervals along the left and right direction on the lower side of the support plate 1, and the arrangement of the two clamping assemblies is the same. Taking one of the clamping assemblies as an example, the following description will be provided. Specifically, two driving components 3 are mounted opposite each other on the underside of the support plate 1 in the front-to-back direction, and the output directions of the two driving components 3 are opposite. The output end of each driving component 3 is connected to a clamping plate 4, so that the two clamping plates 4 are located on the front and rear sides of the support plate 1, respectively. That is, two clamping plates 4 are spaced apart in the left-to-right direction on the front side of the support plate 1, and two clamping plates 4 are spaced apart in the left-to-right direction on the rear side of the support plate 1, so that the six clamping plates 4 are distributed around the circumference of the cover plate 10 to jointly clamp the cover plate 10, thereby improving the stability of clamping the cover plate 10. It should be noted that the six driving components 3 drive the corresponding clamping plates 4 to open or close synchronously, so as to release or clamp the cover plate 10 simultaneously.

[0048] Furthermore, the clamping plate 4 has a contoured groove 41 that matches the edge of the cover plate 10, and the edge of the cover plate 10 is engaged in the corresponding contoured groove 41 of the clamping plate 4. The contoured groove 41 of each cover plate 10 is adapted to the structure of the opposite edge of the cover plate 10 to ensure that the edges of the cover plate 10 at different positions are engaged in the corresponding contoured groove 41. The clamping plate 4 clamps the cover plate 10 by snapping, thereby achieving stable clamping of the cover plate 10 and improving clamping efficiency.

[0049] like Figure 2 and Figure 3As shown, a stop block 5 is also installed on the support plate 1. When the support plate 1 moves to the clamping position, the stop block 5 abuts against the top cover assembly 100. When the support plate 1 descends vertically to the clamping position, the stop block 5 abuts against the cover plate 10 of the top cover assembly 100 to prevent the support plate 1 from descending further. By setting the stop block 5, the maximum displacement of the support plate 1 during descent can be limited, allowing the clamp of the top cover assembly to move accurately to the clamping position, improving the movement accuracy of the clamp of the top cover assembly, thereby ensuring that the clamping plate 4 accurately clamps the cover plate 10 and improving clamping efficiency.

[0050] Specifically, in this embodiment, there are two stop blocks 5. The two stop blocks 5 are installed at intervals along the left and right directions on the lower side of the support plate 1, so that the two stop blocks 5 respectively abut against the two ends of the cover plate 10 in the length direction (left and right direction in the figure) to ensure that the cover plate 10 is evenly stressed and to prevent the cover plate 10 from tilting or shifting position.

[0051] For ease of understanding, the detailed process of the clamps of the top cover assembly picking up the loose top cover assembly 100 is as follows:

[0052] First, the clamps of the top cover assembly are positioned directly above the clamping station. Six drive units 3 drive six clamping plates 4 to move away from the support plate 1, so that the six clamping plates 4 unfold synchronously. Then, the lifting drive unit drives the support plate 1 to descend vertically to the clamping station, and the stop block 5 abuts against the cover plate 10, stopping the descent of the support plate 1. At this time, the elastic element in the pre-tightening assembly 2 is compressed, and the pressure head 22 elastically presses against the cover plate 10, achieving the pre-positioning of the cover plate 10. The suction ports at the large ends of the two suction cups 23 elastically press against the corresponding pole posts 20, and the vacuum generator is turned on, so that the two suction cups 23 respectively vacuum-adsorb the corresponding pole posts 20 to lock the relative position of the pole posts 20 and the cover plate 10. Then, the six drive units 3 synchronously drive the six clamping plates 4 to move towards the support plate 1, so that the six clamping plates 4 retract and clamp the edge of the cover plate 10. At this time, the edge of the cover plate 10 is engaged in the contour groove 41 of the corresponding clamping plate 4. Finally, the lifting drive unit drives the support plate 1 to rise vertically, thereby leaving the clamping station to complete the clamping process of the loose top cover assembly 100.

[0053] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
