[0041] Embodiment

[0042] Please refer to Figure 1 , this embodiment provides a fixture, specifically an auxiliary fixture for limiting the top cover of the battery cell after it is put into the shell. The fixture has a first direction X, and the fixture includes a driving mechanism 100, a first clamping member 200, and a second clamping member 300.

[0043] Among them, the first clamping member 200 includes a first clamping portion 2001 and a second clamping portion 2002, and the first clamping portion 2001 and the second clamping portion 2002 are connected to the driving mechanism 100. The driving mechanism 100 drives at least one of the first clamping portion 2001 and the second clamping portion 2002 to move along the first direction X for jointly clamping the housing 10 of the battery cell.

[0044] It can be understood that it may be that the first clamping portion 2001 remains stationary, and the driving mechanism 100 drives the second clamping portion 2002 to move along the first direction X, so that the first clamping portion 2001 and the second clamping portion 2002 approach each other, thereby clamping the housing 10 of the battery cell. Or, it may also be that the second clamping portion 2002 remains stationary, and the driving mechanism 100 drives the first clamping portion 2001 to move along the first direction X, so that the first clamping portion 2001 and the second clamping portion 2002 approach each other, thereby clamping the housing 10 of the battery cell. Or, it may also be that the driving mechanism 100 simultaneously drives the first clamping portion 2001 and the second clamping portion 2002 to move along the first direction X, so that the first clamping portion 2001 and the second clamping portion 2002 approach each other, thereby clamping the housing 10 of the battery cell. This embodiment does not limit this.

[0045] In addition, a plurality of second clamping members 300 are provided, and the plurality of second clamping members 300 are respectively connected to the first clamping portion 2001 and the second clamping portion 2002. When the first clamping portion 2001 and the second clamping portion 2002 approach each other, the plurality of second clamping members 300 also approach each other for clamping the top cover 20 of the battery cell.

[0046] When using the above fixture to carry the battery cell after being inserted into the housing, the driving mechanism 100 drives at least one of the first clamping portion 2001 and the second clamping portion 2002, so that the first clamping portion 2001 and the second clamping portion 2002 approach each other and clamp the housing 10 of the battery cell. At the same time, the first clamping portion 2001 and the second clamping portion 2002 respectively drive the plurality of second clamping members 300 to approach each other, clamp the top cover 20 of the battery cell, and keep the top cover 20 relatively fixed with respect to the housing 10, so as to ensure that the battery cell body will not fall out of the housing 10 and avoid the battery cell body being dropped and scrapped.

[0047] In some embodiments, the driving mechanism 100 is composed of a power member 110 and a driving member 120.

[0048] Among them, the driving member 120 is connected to the first clamping portion 2001 and the second clamping portion 2002. The power member 110 drives the driving member 120 to move, thereby driving the first clamping portion 2001 and / or the second clamping portion 2002 to move.

[0049] Understandably, the number of driving members 120 can be one. One of the first clamping portion 2001 and the second clamping portion 2002 is connected to a stationary member (such as a housing, a base, etc.) of the power member 110 and remains stationary. The other of the first clamping portion 2001 and the second clamping portion 2002 is connected to the driving member 120, and the power member 110 drives the driving member 120 to move, thereby driving the other of the first clamping portion 2001 and the second clamping portion 2002 to move, so that the first clamping portion 2001 and the second clamping portion 2002 approach each other.

[0050] Alternatively, the number of driving members 120 can also be two. The first clamping portion 2001 is connected to one of the driving members 120, and the second clamping portion 2002 is connected to the other driving member 120. The power member 110 drives the two driving members 120 to move, so that the two driving members 120 approach each other, and further the first clamping portion 2001 and the second clamping portion 2002 approach each other.

[0051] Exemplarily, the power member 110 employs a double-rod piston cylinder, and pistons rods extend from both ends of it along the axial direction. Correspondingly, the driving member 120 employs driving blocks, and the number of driving blocks is two. The piston rod at one end of the double-rod piston cylinder is connected to one of the driving blocks, and further connected to the first clamping portion 2001. The piston rod at the other end of the double-rod piston cylinder is connected to the other driving block, and further connected to the second clamping portion 2002. When in use, the piston rods at both ends of the double-rod piston cylinder retract simultaneously, driving the first clamping portion 2001 and the second clamping portion 2002 to approach each other through the driving blocks to clamp the housing 10 of the battery cell. Alternatively, the piston rods at both ends of the double-rod piston cylinder extend simultaneously, driving the first clamping portion 2001 and the second clamping portion 2002 to move away from each other through the driving blocks to release the housing 10 of the battery cell.

[0052] Alternatively, the power member 110 employs 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 provided on the lead screw. Correspondingly, the driving member 120 employs nut seats, and the number of nut seats is two. Both nut seats are sleeved on the lead screw. One nut seat is in threaded cooperation with the lead screw through the right-handed thread and is connected to the first clamping portion 2001; the other nut seat is in threaded cooperation with the lead screw through the left-handed thread and is connected to the second clamping portion 2002. When in use, the servo motor drives the lead screw to rotate, while the nut seats do not rotate. Since the two nut seats are respectively in threaded cooperation with the lead screw through the right-handed thread and the left-handed thread, the two nut seats translate along the axial direction of the lead screw, and the moving directions of the two nut seats are opposite, driving the first clamping portion 2001 and the second clamping portion 2002 to approach each other or move away from each other.

[0053] Please refer to Figure 1 and Figure 2, in some embodiments, the above fixture further includes an elastic pad 500. There are two elastic pads 500, and both elastic pads 500 are composed of a buffer portion 510 and a supporting portion 520 that are connected to each other.

[0054] The two buffer portions 510 are respectively arranged on the first clamping portion 2001 and the second clamping portion 2002. When the first clamping portion 2001 and the second clamping portion 2002 approach each other, the first side 11 of the housing 10 is clamped through the buffer portion 510.

[0055] Meanwhile, when the first clamping portion 2001 and the second clamping portion 2002 clamp the housing 10, the supporting portion 520 abuts against the second side 12 of the housing 10.

[0056] Among them, the first side 11 is adjacent to the second side 12.

[0057] On the one hand, taking the first clamping portion 2001 as an example, when the first clamping portion 2001 clamps the housing 10 through the elastic buffer portion 510, the buffer portion 510 undergoes elastic deformation and fully adheres to the surfaces of the first clamping portion 2001 and the housing 10 respectively, which can disperse the clamping force applied by the first clamping portion 2001 to the housing 10, enabling the housing 10 to be uniformly stressed, and thus making the housing 10 not easily deformed. In addition, the first clamping portion 2001 clamps the housing 10 through the buffer portion 510 and does not directly contact the housing 10, which can avoid scratching the surface of the housing 10 by the rigid first clamping portion 2001 and affecting the product appearance.

[0058] On the other hand, when the first clamping portion 2001 and the second clamping portion 2002 clamp the housing 10, the supporting portion 520 abuts against the second side 12 of the housing 10, thereby lifting the housing 10, and can clamp and fix the housing 10 more stably, making the housing 10 not easily shake or even become loose during handling.

[0059] Taking Figure 2 the shown perspective as an example, the left and right sides of the housing 10 in the horizontal direction are respectively the first side 11, and the first side 11 is adjacent to the opening of the housing 10, and the lower side of the housing 10 in the vertical direction is the second side 12.

[0060] Exemplarily, the elastic pad 500 can be made of rubber material, polyurethane material, or other elastic materials, and this embodiment does not limit this.

[0061] In addition, the buffer portion 510 is arranged vertically, the supporting portion 520 is arranged horizontally, and one end of the supporting portion 520 close to the first clamping portion 2001 (or the second clamping portion 2002) in the horizontal direction is connected to the bottom end of the buffer portion 510. Among them, the buffer portion 510 and the supporting portion 520 can be integrally formed.

[0062] Please refer toFigure 1 and Figure 3 , in some embodiments, the above-mentioned fixture further includes two connecting members 400. The two connecting members 400 are respectively connected to the first clamping portion 2001 and the second clamping portion 2002.

[0063] Specifically, one of the connecting members 400 is connected to the first clamping portion 2001 and is also connected to the second clamping member 300, so that the second clamping member 300 is connected to the first clamping portion 2001. The other connecting member is connected to the second clamping portion 2002 and is also connected to the second clamping member 300, so that the second clamping member 300 is connected to the second clamping portion 2002. Wherein, the two connecting members 400 are respectively connected to different second clamping members 300.

[0064] During use, the first clamping portion 2001 and the second clamping portion 2002 are used to jointly clamp the housing 10 of the battery cell, the second clamping member 300 is used to clamp the top cover 20 of the battery cell, and the clamping areas of the first clamping portion 2001 and the second clamping portion 2002 deviate from the clamping area of the second clamping member 300. On this basis, by providing the connecting members 400 to connect the first clamping portion 2001 and the second clamping portion 2002 to the second clamping member 300 respectively, the structure of the above-mentioned fixture can be made more concise and compact, and it is convenient for design and processing.

[0065] Furthermore, the fixture further has a second direction Y, and the second direction Y is perpendicular to the first direction X.

[0066] There are two driving members 120. The two driving members 120 approach or move away from each other along the first direction X, and then drive the first clamping portion 2001 and the second clamping portion 2002 to approach or move away from each other along the first direction X to clamp or release the housing 10 of the battery cell, and at the same time drive the second clamping member 300 to approach or move away from each other along the first direction X to clamp or release the top cover 20 of the battery cell.

[0067] In addition, a first adjustment groove 410 is provided on the connecting member 400 along the second direction Y. A first fastener is inserted into the first adjustment groove 410. The two connecting members 400 are respectively connected to the first clamping portion 2001 and the second clamping portion 2002 through the first fastener.

[0068] Understandably, taking the first clamping part 2001 as an example, the first clamping part 2001 is preferably clamped and fixed at the middle part of the housing 10 along the second direction Y, so as to clamp the housing 10 more stably. At the same time, the second clamping member 300 clamps the top cover 20 at the opening of the housing 10. Therefore, the distance between the clamping area of the first clamping part 2001 and the clamping area of the second clamping member 300 depends on the length of the housing 10 along the second direction Y. When the model of the battery cell clamped by the above fixture changes, the length of the housing 10 along the second direction Y changes accordingly, and the distance between the clamping area of the first clamping part 2001 and the clamping area of the second clamping member 300 also changes accordingly.

[0069] At this time, the user can release the connection between the first fastener and the connecting member 400 or the first clamping part 2001, and then translate the connecting member 400 along the second direction Y relative to the first clamping part 2001, driving the second clamping member 300 to translate along the second direction Y relative to the first clamping part 2001 until the distance between the clamping area of the first clamping part 2001 and the clamping area of the second clamping member 300 is again adapted to the length of the housing 10 along the second direction Y. Specifically, when the first clamping part 2001 clamps the middle part of the housing 10 along the second direction Y, the second clamping member 300 is exactly located at the opening of the housing 10 and clamps the top cover 20. Finally, the user can fix and connect the connecting member 400 and the first clamping part 2001 again by using the first fastener.

[0070] Exemplarily, the first fastener is a screw. The rod part of the screw passes through the first adjustment slot 410 and is in threaded cooperation with the first clamping part 2001. The user tightens the screw so that the head of the screw abuts against the connecting member 400 and presses the connecting member 400 against the first clamping part 2001, and then the connecting member 400 and the first clamping part 2001 can be fixedly connected by the friction force between the head of the screw and the connecting member 400 and between the connecting member 400 and the first clamping part 2001. On the contrary, the user loosens the screw so that the head of the screw no longer abuts against the connecting member 400, then the connecting member 400 can be released, and then the connecting member 400 is translated along the second direction Y relative to the first clamping part 2001 until the distance between the clamping area of the first clamping part 2001 and the clamping area of the second clamping member 300 is again adapted to the length of the housing 10 along the second direction Y, and finally the screw is tightened again. During this process, the rod part of the screw slides in the first adjustment slot 410 relative to the connecting member 400, and the user does not have to completely remove the screw.

[0071] Alternatively, the first fastener uses a screw and a nut. One end of the screw is fixedly connected to the first clamping portion 2001. The other end of the screw passes through the first adjustment groove 410 and is in threaded cooperation with the nut. The user tightens the nut so that the nut abuts against the connecting member 400 and presses the connecting member 400 against the first clamping portion 2001. Then, the frictional force between the head of the nut and the connecting member 400 and between the connecting member 400 and the first clamping portion 2001 can be used to fixedly connect the connecting member 400 and the first clamping portion 2001. Conversely, the user loosens the nut so that the nut no longer abuts against the connecting member 400, then the connecting member 400 can be released. Then, the connecting member 400 is translated relative to the first clamping portion 2001 along the second direction Y until the distance between the clamping area of the first clamping portion 2001 and the clamping area of the second clamping member 300 is again adapted to the length of the housing 10 along the second direction Y. Finally, the nut is tightened again. During this process, the screw slides in the first adjustment groove 410 relative to the connecting member 400, and the user does not have to completely remove the nut.

[0072] The adjustment method between the second clamping portion 2002 and the corresponding second clamping member 300 is the same and will not be elaborated here.

[0073] Further, first limiting grooves 210 are provided on the first clamping portion 2001 and the second clamping portion 2002 along the second direction Y, and at least part of the connecting members 400 are respectively located in the first limiting grooves 210.

[0074] Still taking the first clamping portion 2001 as an example, when adjusting the relative position between the connecting member 400 and the first clamping portion 2001 along the second direction Y, the inner wall of the first limiting groove 210 can limit and guide the connecting member 400 to prevent the connecting member 400 from being misaligned.

[0075] After the adjustment is completed, the inner wall of the first limiting groove 210 can support the connecting member 400 and share the force exerted by the connecting member 400 on the first fastener. In particular, it can share the vertically downward pressure exerted by the connecting member 400 and the second clamping member 300 on the first fastener due to their own gravity, so that the first fastener is not easily deformed and stuck.

[0076] Further, the above fixture further has a third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0077] In addition, a second adjustment groove 320 is provided on the second clamping member 300 along the third direction Z. A second fastener is passed through the second adjustment groove 320, and the second clamping member 300 is connected to the connecting member 400 through the second fastener.

[0078] Understandably, when the model of the battery cell clamped by the above fixture changes, the length of the top cover 20 in the third direction Z changes accordingly. It may occur that the second clamping member 300 can only partially clamp the top cover 20, which may lead to the inability to stably clamp the top cover 20.

[0079] At this time, the user can release the connection between the second fastener and the connecting member 400 or the second clamping member 300, and then translate the second clamping member 300 along the third direction Z relative to the connecting member 400 until the second clamping member 300 completely clamps the top cover 20. Finally, the user can use the second fastener to fixedly connect the second clamping member 300 and the connecting member 400 again.

[0080] Exemplarily, the second fastener uses a screw. The rod portion of the screw passes through the second adjustment groove 320 and is in threaded cooperation with the connecting member 400. The user tightens the screw so that the head of the screw abuts against the second clamping member 300 and presses the second clamping member 300 against the connecting member 400, and the frictional force between the head of the screw and the second clamping member 300 and between the second clamping member 300 and the connecting member 400 can be used to fixedly connect the second clamping member 300 and the connecting member 400. Conversely, the user loosens the screw so that the head of the screw no longer abuts against the second clamping member 300, and the second clamping member 300 can be released. Then, the second clamping member 300 is translated along the third direction Z relative to the connecting member 400 until the second clamping member 300 completely clamps the top cover 20, and finally the screw is tightened again. During this process, the rod portion of the screw slides in the second adjustment groove 320 relative to the second clamping member 300, and the user does not have to completely remove the screw.

[0081] Alternatively, the second fastener uses a screw rod and a nut, and its adjustment process is similar to that of the first fastener, which will not be elaborated here.

[0082] Furthermore, a second limiting groove 420 is provided on the connecting member 400 along the third direction Z, and at least a part of the second clamping member 300 is located in the second limiting groove 420.

[0083] When adjusting the relative position of the second clamping member 300 and the connecting member 400 along the third direction Z, the inner wall of the second limiting groove 420 can limit and guide the second clamping member 300 to prevent the second clamping member 300 from being misaligned.

[0084] After the adjustment is completed, the inner wall of the second limiting groove 420 can support the second clamping member 300 and share the force exerted by the second clamping member 300 on the second fastener. In particular, it can share the force exerted by the second clamping member 300 on the second fastener along the first direction X after receiving the reaction force from the top cover 20, so that the second fastener is not easily deformed and stuck.

[0085] Please refer to Figure 4, in some embodiments, a clamping groove 310 is provided on the second clamping member 300, and the clamping groove 310 is used for clamping with the side of the top cover 20.

[0086] Specifically, the clamping groove 310 is provided on one side of the second clamping member 300 facing the top cover 20 along the first direction X. The clamping groove 310 extends along the third direction Z and clamps with the side of the top cover 20 along the first direction X.

[0087] When the two second clamping members 300 approach each other and clamp the top cover 20 of the battery cell, the side of the top cover 20 is inserted into the clamping groove 310. Under the restriction of the inner wall of the clamping groove 310, the top cover 20 cannot move along the second direction Y, or can only move within a small range, and remains relatively fixed with the housing 10, avoiding the battery cell body from falling out of the opening of the housing 10 along the second direction Y.

[0088] After the clamping groove 310 is provided on the second clamping member 300, the second clamping member 300 can clamp and fix the top cover 20 without having to tightly press against the top cover 20, which can avoid the deformation of the relatively thin top cover 20 due to force.

[0089] In summary, when using the above fixture to handle the battery cell after it is placed in the housing, the user first confirms the length of the housing 10 along the second direction Y and the length of the top cover 20 along the third direction Z according to the model of the battery cell, and then adjusts the relative positions of the connecting member 400 and the first clamping portion 2001, the relative positions of the connecting member 400 and the second clamping portion 2002, and the relative position of the second clamping member 300 and the connecting member 400.

[0090] After the adjustment is completed, move the above fixture so that the first clamping portion 2001 and the second clamping portion 2002 are respectively located on both sides of the housing 10 along the first direction X, and the two second clamping members 300 are located on both sides of the top cover 20 along the first direction X. Subsequently, the power member 110 drives the two driving members 120 to approach each other, thereby making the first clamping portion 2001 and the second clamping portion 2002 approach each other and clamp the housing 10, and at the same time making the two second clamping members 300 approach each other and clamp the top cover 20. At this time, the top cover 20 and the housing 10 remain relatively fixed, and the battery cell can be handled, ensuring that the battery cell body will not fall out of the housing 10 during handling and avoiding the battery cell body from being dropped and scrapped.

[0091] This embodiment also provides a battery cell handling device for handling the battery cell after it is placed in the housing. The battery cell handling device includes the above fixture, which can keep the top cover 20 and the housing 10 relatively fixed during the handling of the battery cell, avoiding the battery cell body from falling out of the housing 10 and being scrapped during handling.

[0092] In all the examples shown and described here, any specific value should be construed as merely exemplary and 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 denote like items in the following figures, and thus, once an item is defined in one figure, it is not necessary to further define and explain it in subsequent figures.

[0094] The above-described embodiments 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 variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
