[0039] Please see Figures 1-3 The present application provides an opening and closing control device of a battery cell clamp, which comprises a first frame body 100, a second frame body 120, a guide component 140 assembly and a power source 130. The first frame body 100 is provided with a bearing platform 110 for bearing a battery cell test board 200, and the battery cell test board 200 is provided with a clamping component 210 for clamping a battery cell. The second frame body 120 is arranged above the bearing platform 110, and the bottom of the second frame body 120 is fixed with an opening and clamping component 121 corresponding to the clamping component in the vertical direction. The guide assembly is arranged between the bearing platform 110 and the second frame body 120 for guiding the relative movement of the second support and the bearing platform 110. The power output end of the power source is connected in transmission with the second frame body 120 for driving the second frame body 120 to move in the vertical direction relative to the bearing platform 110, so as to apply an opening and clamping pressure to the clamping component 210 by the opening and clamping component 121.

[0040] In the present application, the battery cell test board 200 can be an aging board, but is not limited to an aging board, and can also be other components for testing battery cells. The clamping component 210 is also called a clamp. The clamping component 210 is provided with a head end 211 and a tail end 212 (shown in Figure 4 The head end 211 is used for clamping the tab of the battery cell when closed. When a vertical downward pressure is applied to the tail end 212 of the clamping component 210, the clamping opening of the head end 211 can be opened by the principle of leverage. The clamping component 210 is provided with an elastic component. When the pressure of the tail end 212 is released, the clamping opening of the head end 211 can be reset from the open state to the closed state under the elastic force of the elastic component. It should be noted that the clamping component 210 of the present application can adopt the clamping component in the related art.

[0041] In the present embodiment, the battery cell test board 200 comprises a substrate, and the clamping component 210 is provided with one or more. The clamping component 210 can be fixed at a specific position of the substrate. When the clamping component 210 is provided with a plurality of clamping components 210, a plurality of clamping components 210 are arranged in multiple rows on the substrate, and each row comprises a plurality of clamping components 210.

[0042] Please see Figures 1-4In the embodiment, when the power source 130 drives the second frame body 120 to move relative to the bearing platform 110 in the vertical direction, for example, when the power source 130 drives the second frame body 120 to move close to the bearing platform 110, the opening clamping component 121 arranged at the bottom of the second frame body 120 can contact the tail end 212 of the clamping piece 210 and apply a downward pressure to the tail end 212, thereby opening the clamping opening of the head end 211 of the clamping piece 210 through the lever principle, and in the open state, the tab of the battery cell can be placed in the clamping opening of the head end 211; when the power source 130 drives the second frame body 120 to move close to the bearing platform 110, the opening clamping component 121 is away from the clamping piece 210, and when the pressure of the tail end is released, the clamping opening of the head end 211 can be reset from the open state to the closed state under the elastic force of the elastic member, thereby clamping the tab of the battery cell. After such arrangement, the opening and closing of the clamping piece 210 can be stable and controllable, and automatic operation can be realized, thereby avoiding the risk that the tab of the battery cell is easily pulled off or the appearance is poor in the related art.

[0043] In the embodiment, the power source 130 can be a cylinder or a motor, and the device of the application further includes a switch assembly, which can be installed on the first support. The switch assembly is electrically connected with the power source 130, and is used to control the operating state of the power source 130, for example, to control the cylinder or motor to be closed, started or to be in different movement strokes, thereby making the opening clamping component 121 close to or away from the battery cell test board, or making the opening clamping component 121 positioned at a specific position in the vertical direction.

[0044] Continuing to refer to Figures 1-4 In the embodiment, the shape and size of the bearing platform 110 are matched with the shape of the battery cell test board 200, for example, when the battery cell test board 200 is rectangular, the bearing platform 110 is also rectangular, and the area of the bearing platform 110 is larger than the area of the battery cell test board 200, so that the battery cell test board 200 can be completely placed on the bearing platform 110.

[0045] In some embodiments, the first frame body 100 includes four support columns 101, the upper ends of the four support columns 101 are connected with the four corner positions of the bearing platform 110, and the bottom ends of the four support columns 101 are provided with support corners in contact with the ground, so that the four support columns 101 can stably support the bearing platform 110.

[0046] In some embodiments, the second frame body 120 is a frame structure, and the frame structure includes a plurality of longitudinally and transversely connected beam bodies 122, wherein the beam body 122 includes a transverse beam and a longitudinal beam, and the opening clamping component 121 is fixed to the bottom of the beam body 122. The opening clamping component 121 can be made of metal and can be welded or bonded to the bottom of the beam body 122.

[0047] In the embodiment, the opening clamping component 121 is a columnar body extending in the transverse direction, for example, a cylindrical body, or the opening clamping component 121 is in the form of a strip.

[0048] Referring to Figures 1-4 The opening clamping component 121 is provided with at least one, and the clamping piece 210 on the battery cell test plate 200 is provided with at least one row, and at least one opening clamping component 121 corresponds to at least one row of clamping pieces 210 in the vertical direction; it is worth mentioning that the opening clamping component 121 of the present application can be an integral structure, and the opening clamping component 121 of the integral structure corresponds to a plurality of clamping pieces 210. In addition to the integral structure, the opening clamping component 121 can also be a split structure, that is, each clamping piece 210 corresponds to an opening clamping component 121.

[0049] In the present application, the length direction of the opening clamping component 121 is the same as the arrangement direction of the plurality of clamping pieces 210 in each row, and the length of the opening clamping component 121 is greater than the arrangement length of the plurality of clamping pieces 210 in each row. After being arranged in this way, when the second frame body 120 drives the opening clamping component 121 to approach the battery cell test plate 200, the cylindrical opening clamping component 121 can simultaneously contact the plurality of clamping pieces 210 in the corresponding row, so that the clamping openings of the plurality of clamping pieces 210 are opened synchronously. Correspondingly, when the second frame body 120 drives the opening clamping component 121 to move away from the battery cell test plate 200, the clamping openings of the plurality of clamping pieces 210 can be closed synchronously, so that the tabs of the plurality of batteries are clamped at the same time. This facilitates the staff to assemble the plurality of batteries and the plurality of clamping pieces 210 one by one, and the plurality of clamping pieces 210 can be stably controlled during the assembly process, which can improve the work efficiency.

[0050] In the embodiment, a containing space for accommodating the battery cell test plate 200 is formed between the bearing platform 110 and the second frame body 120, and the containing space is provided with a lateral opening; the battery cell test plate 200 is placed into the containing space from the lateral opening, or the battery cell test plate 200 is taken out of the containing space from the lateral opening. The battery cell test plate is provided with a handle on one side of the lateral opening, and the battery cell test plate 200 is moved through the handle.

[0051] The bearing platform 110 is provided with a limiting structure on both sides of the lateral opening, and the limiting structure is used to limit the battery cell test plate 200 to a set position on the upper surface of the bearing platform 110, so that the clamping piece 210 of the battery cell test plate 200 corresponds to the opening clamping component 121 in the vertical direction, and the tail end of the opening clamping component 121 and the clamping piece 210 are precisely contacted.

[0052] In some embodiments, the limiting structure includes a limiting block or a limiting strip arranged on the side edge of the bearing platform 110. When the battery cell test plate 200 is moved in, the limiting block or the limiting strip blocks and limits the side edge of the battery cell test plate 200, so as to avoid the battery cell test plate 200 from deviating from the predetermined position when being taken out or placed.

[0053] In the embodiment, the extending direction of the opening and clamping component 121 is matched with the arrangement direction of the clamping pieces 210 on the battery cell test board 200. For example, when the clamping pieces 210 are arranged in a straight line on the battery cell test board 200, the opening and clamping component 121 extends along the straight line correspondingly.

[0054] In addition, the number of the opening and clamping component 121 is matched with the number of the clamping pieces 210 on the battery cell test board 200. When the clamping pieces 210 are arranged in two rows, three rows or four rows, the opening and clamping component 121 is arranged in two, three or four.

[0055] In the application, the frame structure of the second frame body 120 is formed with a hollow region corresponding to the battery cell placement region on the battery cell test board 200. The hollow region facilitates the staff to assemble or disassemble the battery cell on the battery cell test board 200 from the top of the second frame body 120.

[0056] In some embodiments, the plane where the second frame body 120 is located is parallel to the plane where the bearing platform 110 is located, or the opening and clamping component 121 is parallel to the plane where the bearing platform 110 is located. After such arrangement, when the second frame body 120 is close to the battery cell test board 200, the plurality of opening and clamping components 121 installed at the bottom of the second frame body 120 can simultaneously stably contact with the plurality of rows of clamping pieces 210 on the battery cell test board 200, so that the opening and closing amplitude of the clamping pieces 210 in the plurality of rows is consistent, and the tab of the battery cell can be further prevented from being pulled and broken.

[0057] In some embodiments, the guide assembly includes a plurality of guide pieces 140, the upper ends of the plurality of guide pieces 140 are connected with the second frame body 120, the guide pieces 140 penetrate through the bearing platform 110 and are movable in the vertical direction relative to the bearing platform 110. The guide pieces 140 can be guide columns, optical axes, lead screws or the like, and the bearing platform 110 is provided with through holes for the guide pieces 140 to penetrate through.

[0058] Referring to Figures 1-4 In the embodiment, the guide pieces 140 are four, the four guide columns are distributed at the four corners of the virtual quadrilateral where the second frame body 120 is located, and the power source can synchronously drive the four guide columns to move, thereby ensuring the stability of the relative movement between the second frame body 120 and the bearing platform 110.

[0059] It is worth noting that the number of the power source 130 and the guide pieces 140 is not limited in the application, and the number and installation position of the power source 130 and the guide pieces 140 can be flexibly adjusted according to the actual application scene.

[0060] In some embodiments, the power source 130 is fixed to the bottom of the bearing platform 110 and is arranged at the middle position of the bearing platform 110, and the power output end of the power source faces away from the bearing platform 110.

[0061] When the power source is a cylinder, the power output end can be a telescopic shaft of the cylinder, and the embodiment further comprises a connecting assembly 150 connected with the telescopic shaft of the cylinder, the connecting assembly 150 being perpendicular to the telescopic shaft, the connecting assembly 150 being fixedly connected with lower ends of the four guide members 140, the telescopic shaft being capable of driving the connecting assembly 150 to move when the telescopic shaft is telescoped, and the four guide members 140 being capable of moving synchronously through the connecting assembly 150, so as to improve the operation stability of the second frame body 120.

[0062] The electric cell clamp opening and closing control device provided by the application can contact the clamping piece 210 on the electric cell test board 200 when the power source 130 drives the second frame body 120 to move relative to the bearing platform 110 in the vertical direction, so as to open or close the clamping piece 210. The tab of the electric cell can be placed in the clamping piece 210 in the open state, and the tab can be clamped in the closed state. After being arranged in this way, the opening and closing of the clamping piece 210 are accurately controllable, and automatic operation can be realized, so as to avoid the risk that the tab of the electric cell is easily pulled off or the appearance is poor in manual opening of the clamp in the related art, improve the appearance reliability, improve the yield rate, and improve the safety performance of the electric cell.
