Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.

The battery capacity is one of important technical indexes for evaluating the quality of the battery, so that the battery cell is taken as an important component of the battery, and the detection of the battery cell capacity is very important. However, in the production process of the battery, a complete charge-discharge experiment is often required to be performed on the battery cell to detect the capacity of the battery cell. At present, when detecting the battery cells with different sizes, different clamps are generally adopted to clamp the corresponding battery cells.

In order to improve the application range of the clamp, the embodiment of the application provides the clamp which comprises a clamping piece and an adjusting piece which can move relatively. The clamping piece and the adjusting piece jointly form a clamping space for clamping the battery cell to be detected, wherein the clamping piece can adjust the size of the clamping space along the first direction, the adjusting piece can adjust the size of the clamping space along the second direction and can enable the lug of the battery cell to be detected to be capable of protruding the clamping space and be in contact with a testing device for executing the battery cell capacity test so as to conduct the battery cell capacity test. Thus, the clamp can clamp the battery cells with different sizes.

The clamp can be applied to not only the capacity test of the battery cell, but also the procedure of clamping the battery cell. The following describes the fixture in connection with its application to the capacity testing of a battery cell.

Referring to fig. 1 and 2, some embodiments of the present application provide a fixture 100 for testing the capacity of a battery cell. The fixture 100 includes a clamping mechanism 10. The clamping mechanism 10 comprises a clamping piece 11 and an adjusting piece 12 which is movable relative to the clamping piece 11, a clamping space 20 for clamping the battery cell 50 to be detected is formed between the clamping piece 11 and the adjusting piece 12, the clamping piece 11 can adjust the size of the clamping space 20 along a first direction X, the adjusting piece 12 can adjust the size of the clamping space 20 along a second direction Y, and the adjusting piece 12 can push the battery cell 50 to be detected in the adjusting process so as to adjust the height of protruding lug sides of the battery cell 50 to be detected in the clamping space 20; wherein the first direction X intersects the second direction Y.

Both the clamping member 11 and the adjustment member 12 may be connected together, or the clamping member 11 and the adjustment member 12 may be mounted to different components. The movement of the clamping member 11 and the adjusting member 12 may be, but not limited to, a sliding connection or a snap-fit connection.

For example, when the fixture 100 is used, the clamping member 11 may be adjusted in the first direction X according to the size of the battery cell 50 to be tested, so that the battery cell 50 to be tested can enter the clamping space 20 and be primarily clamped by the clamping member 11. At this time, the cell 50 to be detected may or may not be in contact with the regulating member 12. Because the tab of the to-be-detected cell 50 is located at a side far from the adjusting member 12 when the to-be-detected cell 50 is clamped, when the adjusting member 12 is pushed, the adjusting member 12 can contact the to-be-detected cell 50 and push the to-be-detected cell 50 to move along the second direction Y, until the tab of the to-be-detected cell 50 moves along the second direction Y to a position where the tab can contact a testing device for performing the cell capacity test, and the adjusting member 12 stops moving. Typically, the final stop position of the tab of the cell 50 to be tested is exposed outside the clamping space 20.

When the movement of the adjusting member 12 is stopped, the clamping member 11 can be readjusted to clamp the cell 50 to be tested in the first direction X. After the to-be-detected battery cell 50 is clamped, the to-be-detected battery cell 50 can be subjected to a battery cell capacity test.

The clamp 100 changes the size of the clamping space 20 of the clamp 100 by adjusting the clamping member 11 and the adjusting member 12 so as to clamp the battery cells with different sizes, thereby expanding the application range of the clamp 100 and facilitating the operation of a user. And the adjusting member 12 can adjust the positions of the tabs of different cells so that the tabs can smoothly contact with the testing device to perform the cell capacity test on the cells 50 to be tested.

In the practical application process, the size range of the to-be-detected battery cell 50 which can be clamped by the clamp 100 can be the following numerical value, the length of the to-be-detected battery cell 50 can be 100mm-200mm, the length and width of the to-be-detected battery cell 50 can be 35 mm-60 mm, and the height of the to-be-detected battery cell 50 can be 50mm-250mm.

Referring to fig. 2, in some embodiments, the clamping member 11 includes at least two clamping portions 111, and the at least two clamping portions 111 are divided into two groups and are distributed at intervals along the first direction X, and the two groups and the adjusting member 12 together form a clamping space 20.

Illustratively, when the number of the clamping portions 111 is two, each clamping portion 111 is divided into one group. The two groups are distributed at intervals along the first direction X, and the interval between the two groups is adjustable. The user can adjust any clamping part 111 to push the cell 50 to be tested to move along the first direction X. When the cell 50 to be tested is clamped by the clamp 100, the cell 50 to be tested is located between the two groups and can be pushed by the adjusting member 12 and move along the second direction Y.

So set up, not only make things convenient for the user to operate, can also improve the flexibility of use of holder 11, be convenient for remove the utmost point ear of waiting to detect electric core 50 to preset position to wait to detect electric core 50 and carry out electric core capacity test.

Similarly, when the number of the clamping portions 111 is three, two clamping portions 111 are divided into one group, and the other clamping portion 111 is divided into one group. When the number of the clamping portions 111 is greater than three, two or more clamping portions 111 are divided into a group, and detailed description thereof is omitted.

Further, referring to fig. 2, in some embodiments, the clamping member 11 further includes a mounting guide portion 112, and all the clamping portions 111 are movably mounted to the mounting guide portion 112 along the first direction X.

The installation guide 112 may be, but not limited to, a guide rail, a guide groove, the installation guide 112 may extend in the first direction X, and the clamping portion 111 may be connected to any portion of the installation guide 112.

In this way, the clamping portion 111 is guided in the first direction X by the installation guide portion 112, so as to accelerate the movement efficiency of the clamping portion 111 in the first direction X.

Still further, as shown in fig. 2, in some embodiments, the mounting guide portion 112 includes at least one guide groove, two adjacent guide grooves are spaced apart along the second direction Y, and each guide groove extends along the first direction X and is slidably connected to the clamping portion 111.

Illustratively, in the example shown in fig. 2, the mounting guide 112 includes three guide grooves that are spaced apart along the second direction Y. Different parts of the clamping part 111 can be slidably connected with different guide grooves. This can improve the connection stability between the clamping portion 111 and the installation guide portion 112 without affecting the movement efficiency of the clamping portion 111.

The specific number of the guide grooves can be increased or decreased according to actual situations.

In some embodiments, the clamping mechanism 10 further includes a first locking member (not shown) that extends through the mounting guide 112 and secures the clamping portion 111 to the mounting guide 112.

The first locking member may be, but is not limited to, a bolt. For example, in the example shown in fig. 2, the first locking member may pass through the guide groove to be connected with the clamping portion 111, thereby fixing the clamping portion 111 to the mounting guide portion 112. When the size of the cell 50 to be detected changes, the first locking member can be adjusted to change the fixing position of the clamping portion 111 to the corresponding portion of the mounting guiding portion 112, so as to adapt to the cells with different sizes.

The above arrangement not only simplifies the connection mode between the clamping part 111 and the installation guiding part 112, but also reduces the adjustment difficulty of the clamping part 111.

In some embodiments, as shown in fig. 2, the adjusting member 12 is movably connected with the clamping portion 111 along the second direction Y.

The connection between the adjusting member 12 and the clamping portion 111 may be, but not limited to, a threaded connection, a snap fit. Mounting the adjustment member 12 directly to the clamping portion 111 can simplify the structure of the jig 100, and no additional components are required to mount the adjustment member 12.

With continued reference to fig. 2, in some embodiments, each clamping portion 111 is provided with a guiding portion 1111, the guiding portion 1111 extends along the second direction Y, and two end portions of the adjusting member 12 are movably connected to one guiding portion 1111.

Illustratively, as shown in FIG. 2, the guides 1111 may be configured as detents. In the first direction X, the adjusting member 12 may include two opposite end portions, and each end portion may extend into the clamping groove and be clamped with the clamping groove.

When the user pushes the regulator 12 in the second direction Y, the guide 1111 may guide the regulator 12 in the second direction Y. Since both end portions of the regulator 12 are connected to the guide portion 1111, the connection stability between the regulator 12 and the guide portion 1111 can be improved without affecting the moving efficiency of the regulator 12 in the second direction Y.

Specifically, as shown in fig. 2, in some embodiments, the clamping mechanism 10 further includes a second locking member (not shown) that passes through the clamping portion 111 and secures the adjustment member 12 to the clamping portion 111.

The second locking member may be, but is not limited to, a bolt, and may pass through the clamping portion 111 to be coupled with the adjustment member 12, thereby fixing the adjustment member 12 to the clamping portion 111. When the size of the battery cell 50 to be detected changes, the position of the battery cell tab in the clamping space 20 changes, and at this time, the adjusting member 12 can be fixed at the corresponding position of the clamping portion 111 by adjusting the second locking member, so that the battery cell tab can protrude out of the clamping space 20.

The arrangement not only simplifies the connection mode between the adjusting piece 12 and the clamping part 111, but also reduces the adjusting difficulty of the adjusting piece 12, thereby being convenient for the user to operate.

Referring to fig. 1, the fixture 100 includes a plurality of clamping mechanisms 10, all of the clamping mechanisms 10 are arranged along a third direction Z, and two adjacent clamping mechanisms 10 are detachably connected; the first direction X, the second direction Y and the third direction Z are intersected in pairs.

The connection between two adjacent clamping mechanisms 10 may be, but is not limited to, a snap fit. When the fixture 100 is used, a plurality of battery cells of the same size or different sizes may be held at a time by the fixture 100. Because all clamping mechanisms 10 are distributed along the third direction Z, all the clamped cells 50 to be tested are limited in the third direction Z. In addition, the clamping mechanism 10 can limit the to-be-detected battery cells 50 in the first direction X and the second direction Y, so that all the to-be-detected battery cells 50 are limited in a plurality of directions, and the clamping effect of the clamp 100 can be improved.

Referring to fig. 3 and 1, in some embodiments, each clamping mechanism 10 includes a first mating portion 13 and a second mating portion 14, and the first mating portion 13 of one of the two adjacent clamping mechanisms 10 is connected to the second mating portion 14 of the other.

The connection between the first mating portion 13 and the second mating portion 14 may be, but is not limited to, threaded connection, or snap-fit. In a manner of facilitating disassembly such as screw connection between the first fitting portion 13 and the second fitting portion 14 and the clamping portion 111, when any one of the first fitting portion 13, the second fitting portion 14 and the clamping portion 111 is damaged, the damaged component can be replaced.

In the third direction Z, the first fitting portion 13 and the second fitting portion 14 are disposed in reverse. When the mating parts of the plurality of holding mechanisms 10 are connected to each other, assuming that the first holding mechanism 10 is located at the intermediate stage, the first mating part 13 of the first holding mechanism 10 and the second mating part 14 of the second holding mechanism 10 are connected, and the second mating part 14 of the second holding mechanism 10 and the first mating part 13 of the third holding mechanism 10 are connected.

In this way, not only the connection stability between the adjacent two clamping mechanisms 10 can be improved, but also the clamping mechanisms 10 can be easily installed or removed when the number of the clamping mechanisms 10 is increased or decreased.

Specifically, in some embodiments, as shown in fig. 3, one of the first mating portion 13 and the second mating portion 14 includes a card slot, and the other includes a buckle that is snapped into engagement with the card slot.

Illustratively, as shown in fig. 3, the first mating portion 13 includes a card slot extending in the third direction Z, and the second mating portion 14 includes a card buckle extending in the third direction Z. When the corresponding matching parts of the two adjacent clamping mechanisms 10 are connected, the corresponding clamping buckles of the matching parts are clamped into the clamping grooves of the corresponding matching parts.

By the arrangement, the structures of the first matching part 13 and the second matching part 14 are simplified, and the manufacturing difficulty of the first matching part 13 and the second matching part 14 is reduced.

More specifically, as shown in fig. 3, in some embodiments, each of the clamping mechanisms 10 is provided with a first mating portion 13 and a second mating portion 14 on both sides in the first direction X.

By the arrangement, a plurality of parts of the clamping mechanisms 10 can be limited, so that the connection stability between two adjacent clamping mechanisms 10 is further improved.

As shown in fig. 1, in some embodiments, the fixture 100 further includes a base 30, in which all of the clamping mechanisms 10 are mounted and which limits all of the clamping mechanisms 10 in the third direction Z.

In this way, the way of limiting all the clamping mechanisms 10 in the third direction Z is simplified, facilitating the transfer of the clamp 100 by the user.

In other embodiments, as shown in FIG. 1, a handle 33 is also provided on the base 30, and a user may act on the handle 33 to effect transfer of the clip 100.

Referring to fig. 1, in some embodiments, the fixture 100 further includes a pushing member 40, where the pushing member 40 is connected to the clamping mechanism 10 located at one end of all the clamping mechanisms 10 in the third direction Z, and the pushing member 40 is capable of pushing all the clamping mechanisms 10 to move relative to the base 30.

In the example shown in fig. 1, the pushing member 40 may include a screw 41 and an operation portion 42 connected to each other, and an end portion of the screw 41 remote from the operation portion 42 may penetrate a wall of the base 30 and abut against one of the clamping mechanisms 10 of all the clamping mechanisms 10. When the user rotates the operation portion 42 to make the screw 41 continuously screwed into the base 30, the clamping mechanism 10 abutted against the screw 41 continuously moves under the driving of the screw 41, so that the rest of the clamping mechanisms 10 are driven to continuously move.

In the third direction Z, since the clamping mechanisms 10 of all the clamping mechanisms 10 far away from the pushing member 40 can be abutted against the wall body of the base 30, all the clamping mechanisms 10 can be limited in the third direction Z under the action of the pushing member 40 and the base 30, and thus the pushing member 40 can press all the clamping mechanisms 10 to position the clamping mechanisms 10 in the third direction Z, so that the to-be-detected battery cells 50 clamped by the clamping mechanisms 10 are positioned.

In some embodiments, the base 30 includes a limiting member 31 and a mounting member 32, where the limiting member 31 and the mounting member 32 together form a receiving space for mounting all the clamping mechanisms 10, the limiting members 31 are spaced apart along a third direction Z, the mounting member 32 extends along the third direction Z, and each clamping mechanism 10 is movably connected with the mounting member 32 along the third direction Z.

The stopper 31 may have a plate shape, but is not limited to, and the mounting member 32 is connected between two adjacent stoppers 31. The mounting member 32 and the clamping mechanism 10 may be, but not limited to, a sliding connection, and when the clamping mechanism 10 moves in the third direction Z, the difficulty of moving the clamping mechanism 10 in the third direction Z may be reduced because the mounting member 32 extends in the third direction Z.

In some embodiments, as shown in fig. 1 and 3, the mounting member 32 includes guide bars extending along the third direction Z, and a plurality of guide bars spaced around an axis extending along the third direction Z, each guide bar being disposed through the clamping mechanism 10.

Each clamping mechanism 10 is provided with a through hole, and the guide rod can penetrate through the corresponding through hole so as to be connected with the clamping mechanism 10. Because the clamping mechanism 10 is provided with the plurality of through holes which are distributed at intervals around the axis extending along the third direction Z, on the basis of simplifying the connection mode between the clamping mechanism 10 and the mounting piece 32, the connection stability between the clamping mechanism 10 and the mounting piece 32 can be improved, and the probability that the clamping mechanism 10 rotates in the moving process, so that the lugs of the clamped battery cell 50 to be detected deviate from the preset position and need to be adjusted, is reduced.

In other embodiments, bearings may be provided at the through holes to reduce friction between the guide bar and the clamping mechanism 10 by using the bearings, thereby reducing the amount of wear of the guide bar and the clamping mechanism 10 due to the reciprocating movement.

Some embodiments of the application provide a battery processing apparatus. The battery processing apparatus includes the jig 100 in any of the embodiments described above. For the relevant contents of the fixture 100, please refer to the relevant contents described above, and the detailed description is omitted herein. The battery processing equipment further comprises a transfer mechanism and a testing device, and the testing device can test the capacity of the battery cell 50 to be detected, which is clamped by the clamp. The transfer mechanism can transfer the battery cell with the tested battery cell to the next procedure.

The clamp 100 of the battery processing apparatus changes the size of the clamping space 20 of the clamp 100 by adjusting the clamping member 11 and the adjusting member 12 to clamp different sized battery cells, expands the use range of the clamp 100, and facilitates the operation of a user. And the adjusting member 12 can adjust the positions of the tabs of different cells so that the tabs can smoothly contact with the testing device to perform the cell capacity test on the cells 50 to be tested.

In addition, the application also provides a battery production line. The battery production line includes the battery processing apparatus in any of the above embodiments. For the relevant content of the battery processing device, please refer to the relevant content described above, and the description thereof is omitted herein. The battery production line also comprises a workpiece conveying line and a stacking mechanism, and the battery cells processed by the battery processing equipment can be conveyed to the stacking mechanism by the workpiece conveying line to form a battery module.

The clamp 100 of the battery production line changes the size of the clamping space 20 of the clamp 100 by adjusting the clamping member 11 and the adjusting member 12 so as to clamp battery cells of different sizes, thereby expanding the use range of the clamp 100 and facilitating the operation of a user. And the adjusting member 12 can adjust the positions of the tabs of different cells so that the tabs can smoothly contact with the testing device to perform the cell capacity test on the cells 50 to be tested.

In particular to one embodiment, as shown in FIG. 1, the fixture 100 includes a pusher 40, a base 30, and a plurality of clamping mechanisms 10 distributed along a third direction Z. All the clamping mechanisms 10 are located within the base 30, each clamping mechanism 10 comprising a clamping member 11 and an adjustment member 12. The clamping member 11 includes clamping portions 111 distributed along the first direction X, and two end portions of the adjusting member 12 are movably connected to one clamping portion 111 along the second direction Y. The screw 41 of the pushing member 40 can be inserted through the wall of the base 30 and abut against a clamping mechanism 10, and the clamping mechanism 10 is the clamping mechanism 10 located at the end in the third direction Z among all the clamping mechanisms 10.

When the fixture 100 is used, the clamping member 11 can be adjusted in the first direction X according to the size of the battery cell 50 to be tested, so that the battery cell 50 to be tested can enter the clamping space 20 and be primarily clamped by the clamping member 11. Then, the adjusting member 12 may be pushed along the second direction Y, so that the battery cell 50 to be detected is pushed by the adjusting member 12 to move along the second direction Y until the tab of the battery cell 50 to be detected can protrude from the clamping space 20. Finally, the pushing member 40 can be acted on to pressurize all the clamping mechanisms 10 in the third direction Z, so as to limit the to-be-detected battery cell 50 in multiple directions. In this way, the tab of the cell 50 to be detected, which is held by the jig 100, can be brought into contact with a test device that performs a cell capacity test to perform the cell capacity test.

The clamp 100 can change the size of the clamping space 20 of the clamp 100 by adjusting the clamping piece 11 and the adjusting piece 12, thereby being convenient for a user to operate, clamping the battery cells with different sizes and expanding the application range of the clamp 100. And the adjusting member 12 can adjust the positions of the tabs of different cells so that the tabs can smoothly contact with the testing device to perform the cell capacity test on the cells 50 to be tested.
