[0037] Embodiment

[0038] Please refer to Figure 1 , this embodiment provides a clamping mechanism, specifically a mechanism for assisting in clamping the top cover. The clamping mechanism has a first direction X and a second direction Y that are perpendicular to each other, and the clamping mechanism is composed of a first clamping assembly 100 and a second clamping assembly 200.

[0039] Among them, the first clamping assembly 100 includes two first clamping members 120. The two first clamping members 120 are arranged opposite to each other along the first direction X, and the two first clamping members 120 can approach each other so that the two first clamping members 120 clamp the housing 11 of the battery cell 10.

[0040] In addition, the second clamping assembly 200 includes a second driving member 210 and a second clamping member 220. The second driving member 210 is capable of driving the second clamping member 220 to move along the second direction Y, so that the second clamping member 220 abuts against the top cover 12 of the battery cell 10.

[0041] When using the above clamping mechanism, the two first clamping members 120 approach each other along the first direction X to clamp the housing 11 of the battery cell 10. At the same time, the second driving member 210 drives the second clamping member 220 to move along the second direction Y, so that the second clamping member 220 abuts against the top cover 12 of the battery cell 10.

[0042] On the one hand, the second clamping member 220 abuts against the top cover 12, and the top cover 12 further presses the tab, causing the tab to undergo elastic deformation. Under the action of the pressure applied by the second clamping member 220 to the top cover 12 and the elastic force applied by the tab to the top cover 12, the top cover 12 is not easily shaken along the second direction Y.

[0043] On the other hand, the second clamping member 220 abuts against the top cover 12, and there is a certain static friction force between the second clamping member 220 and the top cover 12, making the top cover 12 not easily shaken in any direction perpendicular to the second direction Y.

[0044] On this basis, keeping the second clamping assembly 200 relatively fixed with the first clamping assembly 100 can clamp the top cover 12 on the battery cell 10. Therefore, during the process of transporting the battery cell 10, the top cover 12 is not easily shaken, thus not easily causing product defects such as tab tearing.

[0045] In some embodiments, the first clamping assembly 100 further includes a first driving member 110 for driving the first clamping member 120.

[0046] The first driving member 110 is used to connect with the manipulator and is capable of driving the two first clamping members 120 to approach or separate from each other.

[0047] In the initial state, the two first clamping members 120 are separated from each other. The manipulator drives the first driving member 110 to move, and then drives the entire first clamping assembly 100 to move. When the two first clamping members 120 move to both sides of the housing 11 along the first direction X, the first driving member 110 drives the two first clamping members 120 to approach each other so as to clamp the housing 11. Subsequently, the manipulator drives the first driving member 110 to move again, and then the battery cell 10 can be transported. During this process, the second clamping assembly 200 and the first driving member 110 remain relatively fixed. After the battery cell 10 is transported in place, the first driving member 110 drives the two first clamping members 120 to separate from each other, releases the housing 11, and waits to transport the next battery cell 10.

[0048] Specifically, the first driving member 110 has two first driving ends 111 that can approach or move away from each other along the first direction X. One of the first clamping members 120 is connected to one of the first driving ends 111, and the other first clamping member 120 is connected to the other first driving end 111. Thus, the first driving member 110 drives the two first clamping members 120 to approach or move away from each other through the two first driving ends 111.

[0049] Exemplarily, the first driving member 110 employs a double-rod piston cylinder, and its axis is parallel to the first direction X. Pistons rods extend from both ends of the double-rod piston cylinder along the axis direction and are respectively connected with first driving blocks. The first driving blocks serve as the first driving ends 111 and are further connected to the first clamping members 120. During use, the piston rods at both ends of the double-rod piston cylinder retract simultaneously, driving the two first clamping members 120 to approach each other through the first driving blocks to clamp the housing 11 of the battery cell 10. Alternatively, the piston rods at both ends of the double-rod piston cylinder extend simultaneously, driving the two first clamping members 120 to move away from each other through the first driving blocks to release the housing 11 of the battery cell 10.

[0050] Alternatively, the first driving member 110 can also adopt a servo motor and a lead screw. One end of the lead screw is connected to the shaft of the servo motor, and a right-handed thread and a left-handed thread are respectively arranged on the lead screw. In addition, two nut seats are sleeved on the lead screw and serve as the first driving ends 111. One of the nut seats is in threaded cooperation with the lead screw through the right-handed thread and is connected to one of the first clamping members 120; the other nut seat is in threaded cooperation with the lead screw through the left-handed thread and is connected to the other first clamping member 120. During use, the servo motor drives the lead screw to rotate, while the nut seats do not rotate. Since the two nut seats are in threaded cooperation with the lead screw through the right-handed thread and the left-handed thread respectively, the two nut seats translate along the axis direction of the lead screw, and the moving directions of the two nut seats are opposite, driving the two first clamping members 120 to approach or move away from each other.

[0051] In some embodiments, the first clamping assembly 100 further includes a first elastic pad 130, and the first elastic pad 130 is arranged on the side of the first clamping member 120 close to the battery cell 10.

[0052] Specifically, the number of the first elastic pads 130 is two. One of the first elastic pads 130 is located on the side of one of the first clamping members 120 close to the battery cell 10, and the other first elastic pad 130 is located on the side of the other first clamping member 120 close to the battery cell 10.

[0053] When the first driving member 110 drives the two first clamping members 120 to approach each other, the two first clamping members 120 respectively abut against the housing 11 through the corresponding first elastic pads 130, thereby clamping and fixing the housing 11. At this time, the first elastic pads 130 are elastically deformed under the extrusion of the first clamping members 120 and the housing 11, and are fully attached to the surfaces of the first clamping members 120 and the housing 11 respectively, capable of dispersing the clamping force applied by the first clamping members 120 to the housing 11, enabling the housing 11 to be uniformly stressed, and thus making it difficult for the housing 11 to be clamped and deformed during handling. In addition, the first clamping members 120 clamp the housing 11 through the first elastic pads 130 without directly contacting the housing 11, which can prevent the rigid first clamping members 120 from scratching the surface of the housing 11, thereby avoiding affecting the appearance of the product.

[0054] Exemplarily, the first elastic pad 130 can be made of rubber material, polyurethane material, or other elastic materials, and this embodiment does not limit this.

[0055] Please refer to Figure 2 , further, the first elastic pad 130 is composed of a clamping portion 131 and a supporting portion 132 that are connected to each other.

[0056] Among them, the clamping portion 131 is disposed on the side of the corresponding first clamping member 120 close to the battery cell 10. When the two first clamping members 120 approach each other, they abut against the first side 11a of the housing 11 through the clamping portion 131, thereby clamping and fixing the housing 11.

[0057] Meanwhile, the supporting portion 132 abuts against the second side 11b of the housing 11 when the first clamping member 120 clamps the housing 11.

[0058] Among them, the first side 11a is adjacent to the second side 11b.

[0059] During use, the supporting portion 132 supports the housing 11, capable of more stably clamping and fixing the housing 11, making it difficult for the housing 11 to shake or even become loose during handling.

[0060] Taking Figure 2 the shown perspective as an example, both the left and right sides of the housing 11 in the horizontal direction are the first side 11a, and the first side 11a is adjacent to the opening of the housing 11. The lower side of the housing 11 in the vertical direction is the second side 11b.

[0061] In addition, the clamping portion 131 is vertically disposed, the supporting portion 132 is horizontally disposed, and the end of the supporting portion 132 close to the first clamping member 120 in the horizontal direction is connected to the bottom end of the clamping portion 131. Among them, the clamping portion 131 and the supporting portion 132 can be integrally formed.

[0062] Please refer to Figure 3, in some embodiments, the second driving member 210 has a second driving end 211 that can move back and forth along the second direction Y, and the second clamping member 220 is connected to the second driving end 211.

[0063] During use, the second driving end 211 of the second driving member 210 moves along the second direction Y, thereby driving the second clamping member 220 to move along the second direction Y, so that the second clamping member 220 abuts against the top cover 12 or releases the top cover 12.

[0064] Exemplarily, the second driving member 210 is a cylinder, and its axis is parallel to the second direction Y. A piston rod extends from one end of the cylinder along the axis direction and is connected with a second driving block. The second driving block serves as the second driving end 211 and is further connected to the second clamping member 220. During use, the piston rod of the cylinder retracts, driving the second clamping member 220 to move along the second direction Y towards the top cover 12 through the second driving block, so that the second clamping member 220 abuts against the top cover 12. Alternatively, the piston rod of the cylinder extends, driving the second clamping member 220 to move along the second direction Y away from the top cover 12 through the second driving block, and releasing the top cover 12.

[0065] Or, similar to the first driving member 110, the second driving member 210 can also adopt a servo motor and a lead screw. The difference is that only one nut seat is sleeved on the lead screw as the second driving end 211, which will not be elaborated here.

[0066] In some embodiments, the second clamping assembly 200 further includes a second elastic pad 270, and the second elastic pad 270 is disposed on the side of the second clamping member 220 close to the battery cell 10.

[0067] When the second driving member 210 drives the second clamping member 220 to move along the second direction Y towards the top cover 12, the second clamping member 220 abuts against the top cover 12 through the second elastic pad 270. At this time, the second elastic pad 270 is elastically deformed under the extrusion of the second clamping member 220 and the top cover 12, and is fully attached to the surfaces of the second clamping member 220 and the top cover 12 respectively, capable of dispersing the pressure exerted by the second clamping member 220 on the top cover 12, enabling the top cover 12 to be uniformly stressed, and further making the top cover 12 not easily deformed by abutment during handling. In addition, the second clamping member 220 abuts against the top cover 12 through the second elastic pad 270 and does not directly contact the top cover 12, which can avoid scratching the surface of the top cover 12 by the rigid second clamping member 220, and further avoid affecting the product appearance.

[0068] Exemplarily, the second elastic pad 270 is made of polyether ether ketone (PEEK), which has good wear resistance and a long service life. In addition, the second elastic pad 270 made of polyether ether ketone will not generate metal debris during long-term use, avoiding product safety risks such as short circuits caused by metal debris adhering to the battery cell 10. Alternatively, the second elastic pad 270 can also be made of other non-metallic materials, which is not limited in this embodiment.

[0069] Further, the above clamping mechanism further has a third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0070] In addition, a plurality of mounting holes 221 are provided on the second clamping member 220. The plurality of mounting holes 221 are arranged along the third direction Z, and the second elastic pad 270 is arranged on the second clamping member 220 through the mounting holes 221.

[0071] It can be understood that when the model of the battery cell 10 clamped by the above clamping mechanism changes, the length of the top cover 12 in the third direction Z changes accordingly, and it may occur that the second elastic pad 270 can only partially abut against the top cover 12, resulting in the inability to clamp the top cover 12 on the battery cell 10 feasibly.

[0072] At this time, the user can adjust the second elastic pad 270 to an appropriate position along the third direction Z, and then install the second elastic pad 270 on the second clamping member 220 through the mounting holes 221 at the corresponding positions.

[0073] Exemplarily, the mounting hole 221 is a threaded hole, and a screw that is threadedly engaged with the threaded hole is slidably inserted through the second elastic pad 270, and the second elastic pad 270 is fixed to the second clamping member 220 by the screw.

[0074] Please refer to Figure 3 and Figure 4 , in some embodiments, the second clamping assembly 200 further includes a first mounting seat 230, and the first mounting seat 230 is used to connect with a manipulator. The second driving member 210 is connected to the first mounting seat 230, and the second clamping member 220 is fixedly connected to the second driving member 210.

[0075] During use, the first mounting seat 230 remains relatively fixed with the first driving member 110, so that the second clamping assembly 200 and the first clamping assembly 100 remain relatively fixed during the process of transporting the battery cell 10. For example, the first mounting seat 230 is used to connect with a manipulator, and the manipulator drives the first mounting seat 230 and the first driving member 110 to move simultaneously, thereby driving the entire clamping mechanism to move. Alternatively, the first mounting seat 230 and the first driving member 110 are respectively connected to different manipulators, and the two manipulators remain relatively fixed.

[0076] Further, the second clamping assembly 200 further includes a second mounting base 240. The second driving member 210 is connected to the first mounting base 230 through the second mounting base 240. In addition, the second mounting base 240 can move relative to the first mounting base 230 along the second direction Y.

[0077] Understandably, the first clamping member 120 is preferably clamped and fixed at the middle part of the housing 11 along the second direction Y to clamp the housing 11 more stably. At the same time, the second clamping member 220 abuts against the top cover 12 and is located at the opening of the housing 11. Therefore, the distance between the second clamping member 220 and the first clamping member 120 along the second direction Y depends on the length of the housing 11 along the second direction Y. When the model of the battery cell 10 clamped by the above clamping mechanism changes, the length of the housing 11 along the second direction Y changes accordingly, and the distance between the second clamping member 220 and the first clamping member 120 along the second direction Y also changes accordingly.

[0078] At this time, the user can move the second mounting base 240 relative to the first mounting base 230 along the second direction Y, thereby adjusting the relative position of the second driving member 210 and the first mounting base 230 to ensure that within the moving stroke range of the second driving member 210, the second clamping member 220 can stably and effectively abut against the top cover 12.

[0079] Further, a limiting groove 241 is provided on one side of the second mounting base 240 close to the first mounting base 230. The limiting groove 241 extends along the second direction Y, and at least part of the first mounting base 230 is located in the limiting groove 241.

[0080] When the second mounting base 240 is moved relative to the first mounting base 230 along the second direction Y, the inner wall of the limiting groove 241 is in sliding fit with the first mounting base 230, so as to limit and guide the second mounting base 240 by the first mounting base 230 and prevent the second mounting base 240 from being misaligned with the first mounting base 230 in other directions perpendicular to the second direction Y.

[0081] Further, the second clamping assembly 200 further includes an adjusting member 260 arranged along the second direction Y. The adjusting member 260 is rotatably arranged on the first mounting base 230, and the adjusting member 260 is in threaded fit with the second mounting base 240.

[0082] During use, the user can manually screw the adjusting member 260, thereby driving the second mounting base 240 to move relative to the first mounting base 230 along the second direction Y, which is convenient and fast, and has high adjustment accuracy.

[0083] Exemplarily, the adjusting member 260 is an adjusting screw.

[0084] Further, the second clamping assembly 200 further includes a fastener 250. Correspondingly, an adjustment groove 231 is provided on the first mounting seat 230, and the adjustment groove 231 extends along the second direction Y.

[0085] After the second mounting seat 240 moves relative to the first mounting seat 230, the fastener 250 passes through the adjustment groove 231 and is connected to the second mounting seat 240, thereby locking the second mounting seat 240 on the first mounting seat 230.

[0086] Conversely, before adjusting the relative position between the second mounting seat 240 and the first mounting seat 230, the user needs to first remove the fastener 250, release the second mounting seat 240, and then turn the adjusting member 260.

[0087] Before and after adjustment, the fastener 250 remains relatively fixed with respect to the second mounting seat 240 and slides along the adjustment groove 231 with respect to the first mounting seat 230.

[0088] Exemplarily, the fastener 250 is a fastening screw.

[0089] In summary, when using the above clamping mechanism to carry the battery cell 10, the user first confirms the length of the housing 11 in the second direction Y according to the model of the battery cell 10, and then turns the adjusting member 260 according to this length, so that the second mounting seat 240 moves relative to the first mounting seat 230 along the second direction Y to a suitable position, and then uses the fastener 250 to lock the second mounting seat 240 on the first mounting seat 230.

[0090] After the adjustment is completed, move the above clamping mechanism so that the two first clamping members 120 are located on both sides of the housing 11 along the first direction X, and the second clamping member 220 faces the top cover 12. Subsequently, the first driving member 110 drives the two first clamping members 120 to move closer to each other, so that the two first clamping members 120 clamp the housing 11. At the same time, the second driving member 210 moves the second clamping member 220 along the second direction Y, so that the second clamping member 220 abuts against the top cover 12, thereby clamping the top cover 12 on the battery cell 10. During the process of carrying the battery cell 10, the top cover 12 is not prone to shaking, so that product defects such as ear tearing are not likely to occur.

[0091] This embodiment also provides a battery cell 10 handling device, including the above clamping mechanism, which can clamp the top cover 12 on the battery cell 10 during the process of handling the battery cell 10, so that the top cover 12 is not prone to shaking, thereby not easily causing product defects such as ear tearing.

[0092] In all the examples shown and described here, any specific value should be construed as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0093] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further definition and explanation thereof is not required in subsequent figures.

[0094] The embodiments described above merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
