Description

Technical Field

[0001] The present application relates to the technical field of battery production, and particularly relates to a battery cell detection tooling and a battery production system. Background Art

[0002] With the rapid development of new energy vehicles, the safety of battery cells is the most concerned factor for automobile manufacturers. Every defect in the production process of battery cells may cause major quality problems downstream. In the quality control of battery cells, industrial CT (abbreviation for Computed Tomography, also known as computerized tomography) non-destructive testing can reliably spot-check and identify various defects of battery cells. For battery cells of different sizes, different tilting angles are required for CT scanning. The current problem is that the tilting angle of the battery cell to be tested is not easy to adjust. Summary of the Utility Model

[0003] In view of the above problems, the present application provides a battery cell detection tooling and a battery production system, which are convenient for adjusting the tilting angle of the battery cell, so as to be applicable to CT scanning of battery cells of different sizes.

[0004] In a first aspect, the present application provides a battery cell detection tooling, including:

[0005] A support member, including a rotating member and a supporting member. The rotating member has a first rotation axis, and the rotating member is configured to be able to rotate around the first rotation axis. The supporting member is connected to the rotating member;

[0006] A rotating member, which is cooperated with the supporting member in a rotatable manner. The rotating member has a mounting position for placing the battery cell. The direction of the axis of the rotating member rotating relative to the support member intersects with the first rotation axis;

[0007] An adjusting member, which is in transmission connection with the rotating member. The adjusting member is used for adjusting the rotation angle of the rotating member relative to the support member.

[0008] Through the transmission cooperation between the adjusting member and the rotating member, the adjustment of the tilting angle of the battery cell is realized, so that the tooling can adapt to the CT scanning requirements of battery cells of different specifications, and the versatility of the tooling is improved; at the same time, the rotating member is set to be driven, and the battery cell can be CT scanned from different directions to perform a more comprehensive analysis of the defects of the battery cell.

[0009] In some embodiments, the rotating member includes:

[0010] A rotation fitting member, which has a mounting position; and

[0011] The first clamping member and the second clamping member are respectively arranged in the installation position. The first clamping member and the second clamping member are respectively connected to the rotating fitting member, and the first clamping member and the second clamping member are used to jointly clamp the battery cell.

[0012] The first clamping member and the second clamping member clamp the battery cell. When the battery cell is tilted, it can prevent the battery cell from falling off the support member, so as to reduce the possibility of the battery cell being dropped and damaged from the tooling.

[0013] In some embodiments, along the first direction, at least one of the first clamping member and the second clamping member is connected to the rotating fitting member in a manner that the position relative to the rotating fitting member is adjustable, and the direction of the axis of rotation of the rotating member relative to the support member is the same as the first direction.

[0014] Thus, battery cells of different sizes can be clamped, so as to improve the applicable range of the tooling and reduce the cost required to configure different sizes of tooling due to different sizes of battery cells.

[0015] In some embodiments, the rotating member further includes a first locking member, and the first clamping member is connected to the rotating fitting member through the first locking member;

[0016] The first clamping member is provided with a first long slot hole extending along the first direction, or the rotating fitting member is provided with a first long slot hole extending along the first direction;

[0017] Part of the first locking member is located in the first long slot hole.

[0018] Through the cooperation of the first long slot hole and the first locking member, continuous position adjustment of the first clamping member within a certain range along the first direction is realized to meet the clamping requirements of battery cells of different sizes.

[0019] In some embodiments, the rotating member further includes a second locking member, and the second clamping member is connected to the rotating fitting member through the second locking member;

[0020] The second clamping member is provided with a second long slot hole extending along the first direction, or the rotating fitting member is provided with a second long slot hole extending along the first direction;

[0021] Part of the second locking member is located in the second long slot hole.

[0022] Through the cooperation of the second long slot hole and the second locking member, continuous position adjustment of the second clamping member within a certain range along the first direction is realized to meet the clamping requirements of battery cells of different sizes.

[0023] In some embodiments, along the second direction, the support member is connected to the rotating member in a manner that the position relative to the rotating member is adjustable, and the plane where the axis of rotation of the rotating member relative to the support member and the first rotation axis are located intersects with the second direction.

[0024] For battery cells of different sizes, on the premise that the position of the support member remains unchanged, since the battery cell is tilted at a certain angle, the position where the battery cell deviates from the first rotation axis is also different. By adjusting the position of the support member in the second direction, the battery cell is generally located on the first rotation axis of the rotating member to maintain the relative position between the CT scanning device and the battery cell, thereby improving the consistency of the scanning effect.

[0025] In some embodiments, the support member further includes a linear drive component. The support member is connected to the rotating member through the linear drive component, and the linear drive component is used to adjust the position of the support member relative to the rotating member in the second direction.

[0026] The linear drive component can achieve stepless adjustment of the support member within a certain range to meet the adjustment of the positions of battery cells of different specifications relative to the support member, and improve the applicable range of the tooling.

[0027] In some embodiments, the rotating fitting has a first support surface and a second support surface. The first support surface and the second support surface intersect. The first support surface and the second support surface are respectively used to support different sides of the battery cell, and the first support surface and the second support surface jointly define an installation position.

[0028] The intersection of the first support surface and the second support surface can form a V-shaped or L-shaped support structure to support different types of battery cells (such as cylindrical battery cells or square battery cells, etc.), enhance the versatility of the tooling, and the first support surface and the second support surface support different positions of the battery cell, which can form a more stable support and reduce the possibility of the battery cell detaching.

[0029] In some embodiments, the rotating fitting includes a rotating member, a first support portion, and a second support portion. The first support portion and the second support portion are respectively connected to the rotating member. The rotating member is rotatably connected to the support member. The first support portion forms a first support surface, and the second support portion forms a second support surface.

[0030] The first support portion and the second support portion are respectively connected to the rotating member, and the rotating member is rotatably connected to the support member. Through the cooperation of multiple components, the rotating fitting has the functions of rotation and support, integrating multiple functions of the rotating fitting to make the structure more compact.

[0031] In some embodiments, the rotating fitting is arranged on the support member in a rotatable manner, and the rotating fitting has a first rotation position and a second rotation position;

[0032] When the rotating fitting is in the first rotation position, the first support portion abuts against the support member, and the second support portion is spaced apart from the support member; when the rotating fitting is in the second rotation position, the second support portion abuts against the support member, and the first support portion is spaced apart from the support member.

[0033] Thus, the rotation angle of the rotating member can be limited within a certain range to reduce the possibility of the battery cell colliding with the support member due to excessive angle adjustment, thereby improving the reliability of the tooling.

[0034] In some embodiments, the support member is formed with a partial arc-shaped groove, and the rotating fitting is formed with a partial cylindrical outer surface matching the partial arc-shaped groove.

[0035] Therefore, the rotational engagement of the rotational engagement piece relative to the support component can be achieved through the engagement of the arc-shaped groove with the cylindrical outer surface, making the structure compact and simple and convenient for manufacturing.

[0036] In some embodiments, the adjusting component includes a driving component, which is drivingly connected to the rotating member, and the driving component is used to drive the rotating member to rotate relative to the supporting member.

[0037] The driving component can realize automatic adjustment of the angle of rotation of the rotating component relative to the supporting component. Compared with manual adjustment of the angle, it is more efficient and saves manpower.

[0038] In a second aspect, the present application provides a battery production system, comprising the battery cell inspection tooling and a CT scanning device of the first aspect, wherein the CT scanning device is located on one side of the battery cell inspection tooling, and the CT scanning device is used to perform CT scanning on the battery cell.

[0039] Since the battery production system includes all the technical features of the battery cell inspection tooling of the first aspect, the effects are the same as those described above and will not be repeated here.

[0064] Currently, when placing a battery cell on the tooling for CT scanning, the battery cell needs to be tilted at a certain angle on the tooling for CT scanning to detect whether there are quality defects inside the battery cell. The problem is that for battery cells of different sizes, the required tilting angles are different, and the current tooling cannot meet the requirements of battery cells of multiple specifications, resulting in poor versatility.

[0065] In view of this, the present application provides a battery cell detection tooling, which realizes the adjustment of the tilting angle of the battery cell through the transmission cooperation between the adjustment component and the rotating component, enabling the tooling to adapt to the CT scanning requirements of battery cells of different specifications and breaking through the limitations of traditional fixed-angle detection.

[0066] For the convenience of description in the following embodiments, please refer to Figures 1 - 6 a battery cell detection tooling 100 of the present application as an example for illustration.

[0067] The battery cell detection tooling 100 includes a support member 10, a rotating member 20, and an adjustment component 30. Among them, the rotating member 20 is rotatably connected to the support member 10, and the rotating member 20 has an installation position for placing the battery cell 300. The adjustment component 30 is in transmission connection with the rotating member 20, and the adjustment component 30 is used to adjust the rotation angle of the rotating member 20 relative to the support member 10.

[0068] The shape of the battery cell 300 can be, but is not limited to, Figure 1 square in Figure 2 or cylindrical in

[0069] A member can be a single part or an integral component formed by connecting multiple parts.

[0070] The adjustment component 30 can be an adjustment screw threadedly connected to the support member 10, and a locking nut is provided on the screw, or it can be a driving component 31, such as a motor or other components capable of driving the rotating member 20 to rotate.

[0071] The transmission connection between the adjustment component 30 and the rotating member 20 can be a direct connection, such as welding, threaded connection, or clamping, etc., or it can be connected through an intermediate member.

[0072] By adjusting the transmission cooperation between the adjusting member 30 and the rotating member 20, the inclination angle of the battery cell 300 is adjusted, so that the tooling can adapt to the CT scanning requirements of battery cells 300 of different specifications, and the versatility of the tooling is improved.

[0073] In some embodiments, please refer to Figure 1 , the rotating member 20 includes a rotating fitting 21, a first clamping member 22 and a second clamping member 23. The rotating fitting 21 has a mounting position. The first clamping member 22 and the second clamping member 23 are respectively arranged in the mounting position, the first clamping member 22 and the second clamping member 23 are respectively connected to the rotating fitting 21, and the first clamping member 22 and the second clamping member 23 are used to jointly clamp the battery cell 300.

[0074] The connection between the first clamping member 22 and the second clamping member 23 and the rotating fitting 21 respectively includes screw connection or snap connection, etc. In one example, the first clamping member 22 and the second clamping member 23 are respectively slidably connected to the rotating fitting 21 along the first direction X, and the first clamping member 22 and the second clamping member 23 are connected by a tension spring to be able to clamp the battery cell 300.

[0075] Optionally, the first clamping member 22 and the second clamping member 23 can be plates, specifically bent plates.

[0076] When the first clamping member 22 and the second clamping member 23 clamp the battery cell 300, when the battery cell 300 is inclined, it can prevent the battery cell 300 from falling off the support member, so as to reduce the possibility of the battery cell 300 falling and being damaged from the tooling.

[0077] In some embodiments, please refer to Figure 1 , along the first direction X, at least one of the first clamping member 22 and the second clamping member 23 is connected to the rotating fitting 21 in a manner that the position relative to the rotating fitting 21 is adjustable, and the direction of the axis of rotation of the rotating member 20 relative to the support member 10 is the same as the first direction X.

[0078] As an example, at least one of the first clamping member 22 and the second clamping member 23 can be slidably connected to the support member 10 through a guiding structure, and a set screw is threadedly connected to the one of the first clamping member 22 and the second clamping member 23 that is slidably connected to the support member 10, and the end of the set screw can abut against the guiding structure to limit its movement along the first direction X to realize the clamping of the battery cell 300.

[0079] In another example, the first clamping member 22 and the second clamping member 23 can be respectively connected to two different jaws of a pneumatic clamping mechanism, and the pneumatic clamping mechanism can be a pneumatic jaw.

[0080] Thus, battery cells 300 with different sizes can be clamped, so as to improve the applicable range of the tooling and reduce the cost required for configuring different-sized toolings due to the different sizes of the battery cells 300.

[0081] In some embodiments, please refer to Figure 1 and Figure 6 , the rotating member 20 further includes a first locking member 24. The first clamping member 22 is connected to the rotating fitting member 21 through the first locking member 24. The first clamping member 22 is provided with a first long slot hole 221 extending along the first direction X, or the rotating fitting member 21 is provided with a first long slot hole 221 extending along the first direction X. A part of the first locking member 24 is located in the first long slot hole 221.

[0082] A long slot hole refers to a hole whose length is greater than its own hole diameter.

[0083] The first locking member 24 can be a bolt, a screw, a combination of a screw and a nut, or a combination of a stud and a nut.

[0085] Through the cooperation of the first long slot hole 221 and the first locking member 24, continuous position adjustment of the first clamping member 22 along the first direction X within a certain range is achieved to meet the clamping requirements of battery cells 300 with different sizes.

[0086] In some embodiments, please refer to Figure 1 , the rotating member 20 further includes a second locking member 25. The second clamping member 23 is connected to the rotating fitting member 21 through the second locking member 25. The second clamping member 23 is provided with a second long slot hole 231 extending along the first direction X, or the rotating fitting member 21 is provided with a second long slot hole 231 extending along the first direction X. A part of the second locking member 25 is located in the second long slot hole 231.

[0087] The structure of the second clamping member 23 can be the same as or different from Figure 6 the structure of the first clamping member 22 in

[0088] The second locking member 25 can be a bolt, a screw, a combination of a screw and a nut, or a combination of a stud and a nut.

[0089] As an example, the second long slot hole 231 is provided on the second clamping member 23, the rotating fitting member 21 is provided with a threaded hole, the first locking member 24 is in threaded cooperation with the threaded hole, and the second locking member 25 is disposed through the second long slot hole 231.

[0090] Through the cooperation of the second long slot 231 and the second locking member 25, continuous position adjustment of the second clamping member 23 in a certain range along the first direction X is achieved to meet the clamping requirements of battery cells 300 of different sizes.

[0091] In some embodiments, refer to Figure 1 , the support member 10 includes a rotating member 11 and a supporting member 12. The rotating member 11 has a first rotation axis Z, and the rotating member 11 is configured to rotate around the first rotation axis Z. The direction of the axis of rotation of the rotating member 20 relative to the support member 10 intersects the first rotation axis Z. The supporting member 12 is connected to the rotating member 11, and the rotating member 20 is cooperatively engaged with the supporting member 12 in a rotatable manner.

[0092] The rotating member 11 can be a disc structure or other shapes, such as a square plate, etc.

[0093] The connection between the supporting member 12 and the rotating member 11 includes but is not limited to screw connection, riveting, snap connection, welding, or integral molding, etc.

[0094] The supporting member 12 can be a support base. In one example, the supporting member 12 includes a plate body 122 and a seat body 121. The seat body 121 is connected to the plate body 122, and the two can be fixed by screws, welding, snap connection, or integral molding. The plate body 122 is connected to the rotating member 11, and specifically, it can be fixed by but not limited to screw connection, riveting, snap connection, welding, or integral molding, etc.

[0095] The rotating member 11 is rotatably arranged on a bracket or a workbench, and the rotating member 11 is driven by a motor to rotate around the first rotation axis Z.

[0096] The rotating member 11 is arranged to be driven, and can perform CT scans on the battery cell 300 from different orientations to perform a more comprehensive analysis of the defects of the battery cell 300.

[0097] In some embodiments, refer to Figure 1 , along the second direction Y, the supporting member 12 is connected to the rotating member 11 in a manner that the position of the supporting member 12 relative to the rotating member 11 is adjustable. The plane where the axis of rotation of the rotating member 20 relative to the support member 10 and the first rotation axis Z are located intersects the second direction Y.

[0098] As an example, the rotating member 11 is provided with a guide rail, and the supporting member 12 is slidably connected to the guide rail through a slider. The slider is provided with a set screw, and the set screw can abut against the guide rail. By adjusting the tightness of the set screw, the sliding and fixing of the supporting member 12 relative to the rotating member 11 can be realized, so as to realize the adjustment of the position of the supporting member 12 relative to the rotating member 11 along the second direction Y. In other examples, the rotating member 11 is provided with a third long slot hole, and the rotating member 11 can be threadedly connected to the supporting member 12 through a screw, and the screw is arranged in the third long slot hole, and the length direction of the third long slot hole is the same as the second direction Y.

[0099] For battery cells 300 of different sizes, on the premise that the position of the supporting member 12 remains unchanged, due to the fact that the battery cell 300 is inclined at a certain angle, the position of the battery cell 300 deviating from the first rotation axis Z is also different. By adjusting the position of the supporting member 12 along the second direction Y, the battery cell 300 is generally located on the first rotation axis Z of the rotating member 11, so as to maintain the relative position between the CT scanning device 200 and the battery cell 300, thereby improving the consistency of the scanning effect.

[0100] In some embodiments, please refer to Figure 1 , the support member 10 further includes a linear drive member 13, and the support member 12 is connected to the rotating member 11 through the linear drive member 13. The linear drive member 13 is used to adjust the position of the support member 12 relative to the rotating member 11 along the second direction Y.

[0101] The linear drive member 13 can be a ball screw module or a synchronous belt linear module, etc.

[0102] The linear drive member 13 can realize stepless adjustment of the support member 10 within a certain range, so as to meet the position adjustment of battery cells 300 of different specifications relative to the support member 12, and improve the applicable range of the tooling.

[0103] In some embodiments, the rotating fitting 21 has a first support surface 2121 and a second support surface 2131. The first support surface 2121 and the second support surface 2131 intersect, and the first support surface 2121 and the second support surface 2131 are respectively used to support different positions of the battery cell 300. The first support surface 2121 and the second support surface 2131 jointly define an installation position.

[0104] In one example, both the first support surface 2121 and the second support surface 2131 are planes and are perpendicular to each other. For the square battery cell 300, the bottom surface and the side surface of the battery cell 300 can be in contact with the first support surface 2121 and the second support surface 2131 respectively.

[0105] The first support surface 2121 and the second support surface 2131 intersect, and a V-shaped or L-shaped support structure can be formed to support different types of battery cells 300 (such as cylindrical battery cells or square battery cells, etc.), enhancing the versatility of the tooling. Moreover, the first support surface 2121 and the second support surface 2131 support different positions of the battery cell 300, which can form a more stable support and reduce the possibility of the battery cell 300 detaching.

[0106] In some embodiments, please refer to Figure 1 , the rotating fitting 21 includes a rotating member 211, a first support portion 212, and a second support portion 213. The first support portion 212 and the second support portion 213 are respectively connected to the rotating member. The rotating member 211 is rotatably connected to the support member 10. The first support portion 212 forms a first support surface 2121, and the second support portion 213 forms a second support surface 2131.

[0107] The first support portion 212 and the second support portion 213 are respectively connected to the rotating member 211. The rotating member 211 is rotatably connected to the support member. Through the cooperation of multiple components, the rotating fitting has the functions of rotation and support, integrating multiple functions of the rotating fitting to make the structure more compact.

[0108] In some embodiments, please refer to Figure 1 , the rotating fitting 21 is disposed on the support member 10 in a rotatable manner, and the rotating fitting 21 has a first rotation position and a second rotation position.

[0109] When the rotating fitting 21 is in the first rotation position, the first support portion 212 abuts against the support member 12, and the second support portion 213 is spaced apart from the support member 12; when the rotating fitting 21 is in the second rotation position, the second support portion 213 abuts against the support member 12, and the first support portion 212 is spaced apart from the support member 12.

[0110] Thus, the rotation angle of the rotating member 20 can be limited within a certain range to reduce the possibility that the battery cell 300 collides with the support member 10 due to excessive angle adjustment, thereby improving the reliability of the tooling.

[0111] In some embodiments, please refer to Figure 1 , the support member forms a partial circular arc-shaped groove 1211, and the rotating fitting 21 forms a partial cylindrical outer surface 2111 that matches the partial circular arc-shaped groove 1211.

[0112] The partial circular arc-shaped groove 1211 refers to a groove with a circular arc-shaped cross-section.

[0113] The partial cylindrical outer surface 2111 refers to a protruding partial cylindrical surface.

[0114] The first support portion 212 and the second support portion 213 may be two limiting plates. The two limiting plates can be integrally formed by means of screw connection, welding, riveting or integral molding. The two limiting plates protrude from a part of the cylindrical outer surface 2111 so as to limit the rotation angle when the rotating member 20 rotates.

[0115] Thus, the rotational fit between the rotating fit member 21 and the support member 10 can be realized by the cooperation of the partial circular arc groove 1211 and the partial cylindrical outer surface 2111, making the structure compact and simple and facilitating manufacturing.

[0116] In some embodiments, please refer to Figure 1 , the adjusting member 30 includes a driving member 31. The driving member 31 is in transmission connection with the rotating member 20, and the driving member 31 is used to drive the rotating member 20 to rotate relative to the support member 10.

[0117] The driving member 31 includes a motor, such as a servo motor or a stepper motor. The motor shaft of the motor can be in transmission connection with the rotating member 20 through a coupling. In other examples, the driving member 31 further includes a transmission member. The transmission member can be a speed reducer, a gear transmission mechanism, a synchronous belt transmission mechanism, etc. The motor transmits power to the rotating member 20 through the transmission member to realize the rotation of the rotating member 20 relative to the support member 10.

[0118] The driving member 31 can realize the automatic adjustment of the rotation angle of the rotating member 20 relative to the support member 10. Compared with manual angle adjustment, it has higher efficiency and saves manpower.

[0119] For the convenience of description in the following embodiments, please refer to Figure 2 , and a battery production system in some embodiments of the present application will be taken as an example for description.

[0120] The battery production system includes the battery cell detection tooling 100 and the CT scanning device 200 of the above embodiments. The CT scanning device 200 is located on one side of the battery cell detection tooling 100, and the CT scanning device 200 is used to perform CT scanning on the battery cell 300.

[0121] Since the battery production system includes all the technical features of the battery cell detection tooling 100 in the first aspect, the effects are the same as those described above and will not be elaborated here.

[0122] In a specific optional embodiment of the battery cell detection tooling 100, please refer to Figure 1 and Figure 2, the battery cell detection tooling 100 includes a support member 10, a rotating member 20, and an adjusting member 30. The rotating member 20 includes a rotating fitting 21, a first clamping member 22, and a second clamping member 23. The rotating fitting 21 has a mounting position for placing the battery cell 300. The first clamping member 22 and the second clamping member 23 are respectively disposed in the mounting position. The first clamping member 22 and the second clamping member 23 are respectively connected to the rotating fitting 21, and the first clamping member 22 and the second clamping member 23 are used to jointly clamp the battery cell 300. The rotating fitting 21 is rotatably connected to the support member 10. The adjusting member 30 includes a motor, and the motor shaft of the motor is in transmission connection with the rotating member 20. The motor is used to drive the rotating member 20 to rotate so as to adjust the rotation angle of the rotating member 20 relative to the support member 10. The rotating member 20 further includes a first locking member 24 and a second locking member 25. The first clamping member 22 is provided with a first long slot hole 221 extending along the first direction X. The first clamping member 22 is connected to the rotating fitting 21 through the first locking member 24. One end of the second locking member 25 passes through the first long slot hole 221 and is threadedly connected to the rotating fitting 21. The second clamping member 23 is provided with a second long slot hole 231 extending along the first direction X. One end of the second locking member 25 passes through the second long slot hole 231 and is threadedly connected to the rotating fitting 21. The support member 10 includes a rotating member 11, a support member 12, and a linear driving member 13. The rotating member 11 has a first rotation axis Z. The rotating member 11 is configured to rotate about the first rotation axis Z. The direction of the axis about which the rotating member 20 rotates relative to the support member 10 intersects the first rotation axis Z. The rotating fitting 21 includes a rotating part 211, a first support portion 212, and a second support portion 213. The first support portion 212 and the second support portion 213 are respectively connected to the rotating part. The rotating part 211 is rotatably connected to the support member 12. The first support portion 212 forms a first support surface 2121, and the second support portion 213 forms a second support surface 2131. The support member 12 is connected to the rotating member 11 through the linear driving member 13. The linear driving member 13 is used to adjust the position of the support member 12 relative to the rotating member 11 along the second direction Y. The support member forms a partial circular arc-shaped groove 1211, and the rotating fitting 21 forms a partial cylindrical outer surface 2111 that matches the partial circular arc-shaped groove 1211. The direction of the axis about which the rotating member 20 rotates relative to the support member 10 is the same as the first direction X. The direction of the axis about which the rotating member 20 rotates relative to the support member 10 intersects the first rotation axis Z. The plane where the axis about which the rotating member 20 rotates relative to the support member 10 and the first rotation axis Z are located intersects the second direction Y.

[0123] By adjusting the transmission cooperation between the adjusting member 30 and the rotating member 20, the adjustment of the inclination angle of the battery cell 300 is realized, so that the tooling can adapt to the CT scanning requirements of battery cells 300 of different specifications, breaking through the limitations of traditional fixed-angle detection; at the same time, the first clamping member 22 and the second clamping member 23 are adjustable along the first direction X, and can clamp battery cells 300 of different specifications, improving the versatility of the tooling and reducing the possibility of the battery cell 300 falling during the rotation of the support member 10, improving the reliability of the tooling.
