For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0027] The following will be described in combination with Figures 1 to 6 The cylindrical battery cell clamp and clamp opening device provided by the description of the present application.

[0028] As Figures 1 to 6 shown, the cylindrical battery cell clamp and clamp opening device shown in the embodiment includes a battery cell clamp 1 and a clamp opening mechanism 2.

[0029] The battery cell clamp 1 includes a clamping rack 11 and a plurality of clamping units 12, the plurality of clamping units 12 are arranged on the clamping rack 11 along the length direction of the clamping rack 11, the clamping unit 12 includes oppositely arranged positioning blocks 121 and clamping blocks 122, the positioning blocks 121 and the clamping blocks 122 are connected through elastic components 3; the clamp opening mechanism 2 includes a first driving member 21 and a plurality of push blocks 22, the plurality of push blocks 22 are arranged one-to-one corresponding to the plurality of clamping units 12, the push block 22 and the corresponding clamping block 122 are detachably connected; the first driving member 21 is used to drive the push block 22 along the length direction of the clamping rack 11 to move the clamping block 122 away from the corresponding positioning block 121; the elastic force generated by the elastic component 3 is used to drive the clamping block 122 to move along the length direction of the clamping rack 11 to approach the corresponding positioning block 121 to clamp the battery cell 4.

[0030] Specifically, the cylindrical battery cell clamp and clamp opening device shown in the embodiment, through the clamp opening mechanism 2, the synchronous clamp opening action of the plurality of clamping units 12 on the battery cell clamp 1 is realized, through the elastic force of the elastic component 3, the synchronous clamping action of the plurality of clamping units 12 is realized, the consistency of the clamp opening action and the clamping action is ensured; when a plurality of battery cells 4 need to be clamped, the push block 22 and the corresponding clamping block 122 are connected, the first driving member 21 is opened, the clamping block 122 moves away from the corresponding positioning block 121, the relative distance between the clamping block 122 and the positioning block 121 increases and drives the elastic component 3 to produce deformation, thereby completing the clamp opening action.

[0031] After the transfer device transfers the battery cell 4 between the clamping block 122 and the corresponding positioning block 121 after the clamping has been opened, the first driving member 21 drives the clamping block 122 to move toward the corresponding positioning block 121 via the pusher block 22. At the same time, the elastic force generated by the elastic component 3 in the deformed state also drives the clamping block 122 to move toward the corresponding positioning block 121 until the clamping block 122 and the positioning block 121 contact the battery cell 4. The pusher block 22 separates from the corresponding clamping block 122. Under the action of the elastic force of the elastic component 3, the battery cell 4 is clamped between the clamping block 122 and the positioning block 121, thereby completing the clamping and fixing of the battery cell 4 by the battery cell clamp 1.

[0032] When it is necessary to remove the battery cell 4, the lever 22 connects to the corresponding clamping block 122 again and repeats the above-mentioned opening and closing process. By setting multiple levers 22, multiple clamping blocks 122 are driven to open synchronously, ensuring the consistency of the opening and closing action. During clamping, the clamping block 122 and the positioning block 121 corresponding to each clamping unit 12 are clamped by the elastic force of the elastic component 3, ensuring the consistency of the clamping force and the clamping action of each battery cell 4. This improves the consistency of the clamping action and the opening and closing action, thereby ensuring the reliability of the battery cell 4 clamping and correspondingly improving the production efficiency of the battery cell 4.

[0033] The first driving component 21 can be a cylinder, a hydraulic cylinder, or a linear motor; the length direction of the clamping platform 11 is... Figure 1 and Figure 6 The height direction of the clamping platform 11 is from left to right or from right to left. Figure 1 The direction from top to bottom or from bottom to top.

[0034] In some embodiments, such as Figure 1 and Figure 3 As shown, the clamping mechanism 2 in this embodiment also includes a second driving member 23; the second driving member 23 is located on the lower side of the clamping platform 11 along the height direction of the clamping platform 11; the clamping block 122 is provided with a groove 1221 for accommodating the paddle 22; the second driving member 23 is connected to the first driving member 21; the second driving member 23 is used to drive the first driving member 21 and the paddle 22 to move closer to or away from the groove 1221 along the height direction of the clamping platform 11.

[0035] Specifically, when the clamping mechanism 2 drives the cell clamp 1 to open, the second driving member 23 drives the first driving member 21 and the toggle block 22 to approach the groove 1221 until the toggle block 22 extends into the groove 1221. At this time, the toggle block 22 is connected to the groove 1221, and the first driving member 21 drives the clamping block 122 to move away from the corresponding positioning block 121. After the clamping block 122 and the positioning block 121 clamp the cell, the second driving member 23 drives the first driving member 21 and the toggle block 22 to move away from the groove 1221 until the toggle block 22 exits from the groove 1221. At this time, the toggle block 22 separates from the groove 1221.

[0036] The second driving component 23 can be a cylinder, a hydraulic cylinder, or a linear motor.

[0037] In some embodiments, such as Figure 5 and Figure 6 As shown, the clamping mechanism 2 in this embodiment further includes a first connecting plate 24 and a second connecting plate 25; a plurality of levers 22 are respectively connected to the first connecting plate 24. The first connecting plate 24 is movably disposed on the clamping platform 11 along the length direction of the clamping platform 11. The second connecting plate 25 is provided with a sliding groove 251, and a slider 241 is provided in the sliding groove 251. The slider 241 is connected to the first connecting plate 24. The first driving member 21 is used to drive the second connecting plate 25 to move toward the side closer to the first connecting plate 24 or away from the first connecting plate 24 along the width direction of the clamping platform 11. The extension direction of the sliding groove 251 is set at an acute angle to the width direction of the clamping platform 11.

[0038] Specifically, when the first driving member 21 drives the second connecting plate 25 to move along the width direction of the clamping platform 11, the state of the second connecting plate 25 corresponding to the control of the cell clamp 1 includes two cases. In the first case, when the second connecting plate 25 moves toward the side closer to the first connecting plate 24, the cell clamp 1 opens; when the second connecting plate 25 moves toward the side away from the first connecting plate 24, the cell clamp 1 clamps the cell. In the second case, when the second connecting plate 25 moves toward the side away from the first connecting plate 24, the cell clamp 1 opens; when the second connecting plate 25 moves toward the side closer to the first connecting plate 24, the cell clamp 1 clamps the cell. In the first case, the inclination direction of the slide groove 251 is opposite to that in the second case. The following explanation uses the first case as an example.

[0039] In the process of opening the clamp of the battery cell, the first driving member 21 drives the second connecting plate 25 to move towards the side close to the first connecting plate 24, and since the sliding groove 251 is arranged in an inclined manner, the driving force along the width direction of the clamping rack 11 is decomposed into the driving force along the length direction of the clamping rack 11, and the driving force along the length direction of the clamping rack 11 drives the first connecting plate 24 to move through the sliding block 241, so as to realize the separation of the clamping block 122 from the positioning block 121, thereby completing the opening action; in the process of clamping the battery cell, the first driving member 21 drives the second connecting plate 25 to move towards the side away from the first connecting plate 24, so that the elastic force generated by the elastic assembly 3 clamps the battery cell by the clamping block 122 and the positioning block 121.

[0040] The width direction of the clamping rack 11 is the direction from the top to the bottom or from the bottom to the top. Figure 6 The width direction of the clamping rack 11 is the direction from the top to the bottom or from the bottom to the top.

[0041] Further, as shown in Figure 6 , the sliding block 241 is connected with the sliding groove 151 through a bearing.

[0042] In some embodiments, as shown in Figure 5 and Figure 6 , the first connecting plate 24 shown in the embodiment is provided with two, and the two first connecting plates 24 are arranged along the length direction of the clamping rack 11, and a part of the plurality of poking blocks 22 is arranged on one of the first connecting plates 24, and another part of the plurality of poking blocks 22 is arranged on the other first connecting plate 24; the sliding groove 251 is provided with two, and the two first connecting plates 24 and the two sliding grooves 251 are arranged one by one, and the two sliding grooves 251 are arranged in a V shape; in the case that the first driving member 21 drives the second connecting plate 25 to move along the width direction of the clamping rack 11, the two first connecting plates 24 are away from or close to each other.

[0043] Specifically, the two first connecting plates 24 are arranged in a symmetrical manner, in the case that the second connecting plate 25 moves towards the side close to the first connecting plate 24, the two first connecting plates 24 are away from each other, thereby completing the opening action, and in the case that the second connecting plate 25 moves towards the side away from the first connecting plate 24, the two first connecting plates 24 are close to each other, thereby completing the clamping action, that is, the moving directions of the two first connecting plates 24 are opposite.

[0044] In some embodiments, as shown in Figure 1 , Figure 5 and Figure 6 , the opening clamp mechanism 2 shown in the embodiment further comprises a support 26, the support 26 is located on the lower side of the clamping rack 11 along the height direction of the clamping rack 11, the support 26 is provided with a sliding rail 261, the sliding rail 261 extends along the length direction of the clamping rack 11, and the first connecting plate 24 is movably arranged on the sliding rail 261.

[0045] Specifically, the slide rail 261 plays a guiding role on the first connecting plate 24, so that the first connecting plate 24 and the push block 22 thereon can move stably along the length direction of the clamping rack 11, thereby ensuring the stability of the opening clamping.

[0046] In some embodiments, as shown in Figure 4 and Figure 5 , the first connecting plate 24 shown in the embodiment is provided with a positioning hole 242 matched with the battery cell 4, which is used for the battery cell 4 on the battery cell clamp 1 to extend into.

[0047] Specifically, the positioning hole 242 can play a positioning role on the battery cell 4, and at the same time, when the second driving member 23 lifts the first connecting plate 24, the positioning hole 242 can avoid the bottom of the battery cell 4, so as to facilitate the continuous lifting of the first connecting plate 24, so that the push block 22 can extend into the groove 1221.

[0048] In some embodiments, as shown in Figure 5 and Figure 6 , the cylindrical battery cell clamp and the opening clamping device shown in the embodiment further comprise a battery cell supporting block 5; the battery cell supporting block 5 is provided in plurality, and the plurality of battery cell supporting blocks 5 are arranged one by one corresponding to the plurality of clamping units 12, and the battery cell supporting block 5 is arranged on the lower side of the corresponding clamping unit 12.

[0049] Specifically, in the case of opening the battery cell clamp 1, the transfer device extends the battery cell 4 between the clamping block 122 and the positioning block 121 from top to bottom, and the battery cell supporting block 5 thus plays a supporting role on the battery cell 4 to avoid the falling of the battery cell 4, and then the battery cell 4 is clamped by the clamping block 122 and the positioning block 121; wherein the battery cell supporting block 5 is located in the positioning hole 242.

[0050] In some embodiments, as shown in Figure 2 , the elastic assembly 3 shown in the embodiment comprises a tension spring 31 and a compression spring 32; the clamping block 122 and the corresponding positioning block 121 are connected by the tension spring 31; among the adjacent two clamping units 12, the clamping block 122 of one is connected to the positioning block 121 of the other by the compression spring 32.

[0051] Specifically, the positioning block 121 is fixed on the clamping rack 11, and in the opening clamping, the clamping block 122 is away from the corresponding positioning block 121, the tension spring 31 is stretched and the compression spring 32 is compressed, and in the clamping, the clamping block 122 is close to the positioning block 121 under the action of the tension of the tension spring 31 and the pressure of the compression spring 32, so as to clamp the battery cell 4; the clamping block 122 and the positioning block 121 of the adjacent two clamping units 12 are connected by the compression spring 32, thereby reducing the size of the overall structure in the length direction of the clamping rack 11, so that the structure is more compact.

[0052] In some embodiments, as shown inFigure 2 As shown, the clamping platform 11 in this embodiment is provided with a guide rail 111. The guide rail 111 extends along the length of the clamping platform 11. The clamping block 122 is movably disposed on the guide rail 111. The guide rail 111 guides the clamping block 122, thereby improving the stability of the movement of the clamping block 122.

[0053] In some embodiments, such as Figure 2 As shown in the figure, the clamping block 122 near the positioning block 121 and the positioning block 121 near the clamping block 122 in this embodiment are both provided with arc-shaped grooves. The arc-shaped grooves are adapted to the outer wall surface of the battery cell 4 so that the arc-shaped grooves fit as closely as possible to the outer wall surface of the battery cell 4, and increase the contact area between the battery cell 4 and the clamping block 122 and the positioning block 121, thereby improving the stability of the battery cell 4 clamping.
