[0001] This application relates to the field of battery cell processing equipment technology, specifically to battery cell support and clamping mechanisms and battery cell production lines. Background Technology

[0002] In the production process of lithium-ion batteries, the cells need to be constantly switched between workstations. Due to space constraints, the cells often need to be turned during transport. While conveyor lines that transport cells one by one are relatively simple in structure, the efficiency of individually inspecting each cell at some surface inspection stations is low. To improve inspection efficiency, current methods typically involve transporting cells in groups, i.e., transporting multiple cells as a unit. However, when changing direction, the spacing between cells sometimes needs to be adjusted, requiring individual operation of each cell, which results in low efficiency. Utility Model Content

[0003] This application provides a cell support and clamping mechanism to improve the low efficiency caused by the current technology of operating each cell individually to achieve cell group commutation and pitch change.

[0004] In addition, the purpose of this application is to provide a battery cell production line using the above-mentioned battery cell support and clamping mechanism.

[0005] In a first aspect, some embodiments provide a battery cell support and clamping mechanism, including:

[0006] Base;

[0007] A pitch-changing mechanism includes a pitch-changing base, at least two moving parts, and a pitch-changing drive mechanism. The moving parts are movably mounted on the pitch-changing base, and the pitch-changing drive mechanism is used to drive the moving parts to move relative to the pitch-changing base and change the distance between adjacent moving parts. The pitch-changing base is rotatably mounted on the base.

[0008] A rotary drive mechanism is provided for driving the variable pitch base to rotate.

[0009] The moving member is provided with a gripper mechanism, at least one of the gripper mechanisms being mounted on its upper side. The gripper mechanism includes a first gripper, a second gripper, and a gripper driving mechanism. The gripper driving mechanism is used to drive the first gripper and the second gripper to move closer and further apart to clamp and release the battery cell. The gripper mechanism has a battery cell supporting surface for supporting the battery cell, which is located between the first gripper and the second gripper.

[0010] Furthermore, in some embodiments, the gripper drive mechanism includes a gripper cylinder fixed to the moving member, the gripper mechanism includes a support member fixed to the upper side of the gripper cylinder, and the battery cell support surface is located on the support member.

[0011] Furthermore, in some embodiments, both the first gripper and the second gripper are located above the gripper cylinder, and the support member has a clearance groove through which at least a portion of the first gripper and at least a portion of the second gripper pass.

[0012] Furthermore, in some embodiments, the base includes a seat body and a movable slide, the movable slide being movably mounted on the seat body; the cell support and clamping mechanism further includes a movable slide drive mechanism for driving the movable slide to move relative to the seat body; the variable pitch base is rotatably mounted on the movable slide.

[0013] Furthermore, in some embodiments, the first gripper includes a first gripper arm and a first clamping member for cooperating with the second gripper to clamp the battery cell, the first gripper arm extending in the moving direction of the first gripper; the first clamping member is fixed to the upper side of the first gripper arm and its position relative to the first gripper arm is adjustable along the extending direction of the first gripper arm.

[0014] Furthermore, in some embodiments, the second gripper includes a second gripper arm and a second clamping member for clamping the battery cell, the second gripper arm extending in the movement direction of the second gripper; the second clamping member is fixed to the upper side of the second gripper arm and its position relative to the second gripper arm is adjustable along the extension direction of the second gripper arm.

[0015] Furthermore, in some embodiments, the first clamping member is movably mounted on the first gripper arm, and the first gripper includes a fixing member for fixing the first clamping member to the first gripper arm after the first clamping member has been moved into place.

[0016] Furthermore, in some embodiments, the rotary drive mechanism includes a rotary drive motor, the lower end of which is fixed to the base, and the variable pitch base is fixed to the upper end of the rotary drive motor.

[0017] Furthermore, in some embodiments, the rotary drive motor is a direct drive motor.

[0018] Secondly, some embodiments provide a battery cell production line, including the battery cell support and clamping mechanism described in any embodiment of the first aspect, and further including a first battery cell clamping mechanism for transferring battery cell groups to the battery cell support and clamping mechanism and a second battery cell clamping mechanism for clamping battery cell groups from the battery cell support and clamping mechanism.

[0019] According to the cell support and clamping mechanism of the above embodiment, since the number of moving parts of the pitch-changing mechanism is at least two, and at least one gripper mechanism is installed on the upper side of each moving part, the spacing between the cells can be changed by the pitch-changing mechanism when the gripper mechanism clamps the cell. Since the pitch-changing base of the pitch-changing mechanism is rotatably mounted on the base, the pitch-changing base can be driven to rotate by the rotation drive mechanism, thereby driving each gripper mechanism to rotate simultaneously and change the direction of the cell group. The cell support and clamping mechanism of this application can realize the turning of multiple cells and change the spacing between adjacent cells, improving the low efficiency problem caused by the current method of changing the pitch of the cell group by operating each cell individually.

Therefore, they should not be construed as limitations on this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0032] The embodiments described in the detailed implementation can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different embodiments. In order to avoid unnecessary repetition, the various possible combinations of the embodiments will not be described separately.

[0033] To address the need in some applications to change both the orientation of the battery cell assembly and the spacing between the cells within it, this application provides a battery cell support and clamping mechanism. This mechanism uses a pitch-changing mechanism to alter the spacing between adjacent clamping jaws, and a rotary drive mechanism to rotate the pitch-changing mechanism, achieving synchronous rotation of all clamping jaws. This process realizes both the reversal of the battery cell assembly's orientation and the change in the spacing between adjacent cells. The battery cell support and clamping mechanism of this application will be described in detail below with reference to the accompanying drawings.

[0034] In some embodiments, please refer to Figure 1 and Figure 2 The cell support and clamping mechanism includes a base 1, a pitch-changing mechanism 2, a rotary drive mechanism 3, and a gripper mechanism 4. The pitch-changing mechanism 2 includes a pitch-changing base 21 rotatably mounted on the base 1, at least two moving parts 22, and a pitch-changing drive mechanism. The moving parts 22 are movably mounted on the pitch-changing base 21. The pitch-changing drive mechanism is used to drive the moving parts 22 to move relative to the pitch-changing base 21 and change the distance between adjacent moving parts 22. The rotary drive mechanism 3 is used to drive the pitch-changing base 21 to rotate, thus driving the pitch-changing mechanism 2 to rotate as a whole.

[0035] At least one gripper mechanism 4 is mounted on the upper side of the movable component 22. The gripper mechanism 4 includes a first gripper 41, a second gripper 42, and a gripper drive mechanism 43. The gripper drive mechanism 43 is used to drive the first gripper 41 and the second gripper 42 to move closer and further apart, so as to clamp and release the battery cell. The gripper mechanism 4 has a battery cell support surface 441 for supporting the battery cell, and the battery cell support surface 441 is located between the first gripper 41 and the second gripper 42.

[0036] When the gripper mechanism 4 grips the battery cell, the spacing between the battery cells can be changed by the pitch-changing mechanism 2. Since the pitch-changing base 21 of the pitch-changing mechanism 2 is rotatably mounted on the base 1, the pitch-changing base 21 can be driven to rotate by the rotation drive mechanism 3, thereby driving each gripper mechanism 4 to rotate simultaneously and changing the direction of the battery cell group. In this way, the battery cell support and gripping mechanism can not only achieve the orientation of multiple battery cells, but also change the spacing between adjacent battery cells.

[0037] Regarding the pitch-changing mechanism 2, in some embodiments, the pitch-changing mechanism 2 adopts a mature pitch-changing slide table from the prior art. The pitch-changing drive mechanism can be a lead screw and nut mechanism, using positive and negative threaded screws to drive symmetrical sliders to move in opposite directions, achieving equal-distance pitch changing. The pitch-changing drive mechanism can also be a belt drive mechanism, connecting multiple moving parts 22 via a synchronous belt to ensure motion synchronization. Pitch changing can also be achieved through the folding / unfolding of multi-stage linkages or telescopic rods. Alternatively, it can be a linear motor drive, where the linear motor can independently drive multiple moving parts, with the moving parts 22 mounted on the moving parts, and their positions precisely controlled by the linear motor. The number of moving parts 22 in the pitch-changing mechanism 2 can be two, three, four, or five or more, depending on the needs.

[0038] Furthermore, in some embodiments, please refer to Figure 1 and Figure 2 The gripper drive mechanism 43 includes a gripper cylinder 431 fixed to the moving member 22. The gripper mechanism 4 includes a support member 44, which is fixed to the upper side of the gripper cylinder 431. The battery cell support surface 441 is located on the support member 44. Fixing the support member 44 to the gripper cylinder 431 makes the gripper drive mechanism 43 more compact. Specifically, the support member 44 is fixed to the cylinder body of the gripper cylinder 431. In some other embodiments, the support member 44 can be directly fixed to the moving member 22 in addition to being fixed to the gripper cylinder 431. In addition to the support member 44 supporting the battery cell, in some other embodiments, the top surface of the gripper cylinder 431 can also be used to support the battery cell, in which case the first gripper 41 and the second gripper 42 are located on both sides of the gripper cylinder 431.

[0039] To further reduce the size of the gripper mechanism 4, in some embodiments, please refer to... Figure 1 and Figure 2The first gripper 41 and the second gripper 42 are both located above the gripper cylinder 431. The support member 44 has a clearance groove 444 through which at least a portion of the first gripper 41 and at least a portion of the second gripper 42 passes. Specifically, in some embodiments, the support member 44 includes a support plate 442 and a connecting plate 443. There are two connecting plates 443, and the two support plates 442 are respectively connected to opposite sides of the support plate 442. The two connecting plates 443 are arranged in a U-shape with the support plate 442. The connecting plates 443 are fixed to the cylinder body of the gripper cylinder 431, and the two connecting plates 443 and the support plate 442 form the clearance groove 444. In some embodiments, the support plate 442 and the connecting plate 443 can be either a single integrally formed part or two parts fixed together by assembly.

[0040] In some embodiments, please refer to Figure 1 and Figure 2 The base 1 includes a seat body 11 and a movable slide 12, which is movably mounted on the seat body 11. The cell support and clamping mechanism also includes a movable slide drive mechanism 13 that drives the movable slide 12 to move relative to the seat body 11. A variable pitch base 21 is rotatably mounted on the movable slide 12. In this way, the cell support and clamping mechanism can not only realize the reversal and rotation of the cell assembly, but also realize the translation of the cell assembly. Of course, in some other embodiments, the base 1 can also be a fixed structure, with the variable pitch base 21 fixed on the base 1.

[0041] Specifically, in some embodiments, the movable slide drive mechanism 13 may include a lead screw and nut mechanism that drives the movable slide 12. The lead screw of the lead screw and nut mechanism is driven to rotate by a drive motor 131, and the movable slide 12 is connected to the nut. The drive motor 131 is a servo motor, capable of achieving high-precision position changes; the positioning accuracy of the movable slide drive mechanism 13 can reach 0.02 mm. In other embodiments, the movable slide drive mechanism 13 may also be a belt drive mechanism, with the movable slide 12 connected to a synchronous belt, and the synchronous belt driven by pulleys to realize the movement of the movable slide 12. In still other embodiments, the movable slide drive mechanism 13 may also be a linear motor, which drives the movable slide 12 to move linearly.

[0042] Regarding the structure of the first gripper 41, please refer to some embodiments. Figure 1 and Figure 2The first gripper 41 includes a first gripper arm 411 and a first clamping member 412 for cooperating with the second gripper 42 to clamp the battery cell. The first gripper arm 411 extends in the moving direction of the first gripper 41. The first clamping member 412 is fixed to the upper side of the first gripper arm 411 and its position relative to the first gripper arm 411 is adjustable along the extending direction of the first gripper arm 411. Since the first clamping member 412 is fixed to the first gripper arm 411 and its position is adjustable, the first gripper 41 can adapt to battery cells of different sizes, thus improving the applicability of the gripper mechanism 4.

[0043] Similarly, in some embodiments, please refer to Figure 1 and Figure 2 The second gripper 42 includes a second gripper arm 421 and a second gripping member 422 for gripping the battery cell. The second gripper arm 421 extends in the moving direction of the second gripper 42. The second gripping member 422 is fixed to the upper side of the second gripper arm 421 and its position relative to the second gripper arm 421 is adjustable along the extending direction of the second gripper arm 421. The second gripper 42 can also be adjusted in position relative to the second gripper arm 421 as needed. In this way, the second gripper 42, in cooperation with the first gripper 41, can have a wider adjustment range and is suitable for larger battery cell sizes.

[0044] In some other embodiments, besides the adjustable first gripper 41 and second gripper 42, the first gripper 41 and second gripper 42 may also be used only for cells of one size. In this case, the first clamping member 412 and the first gripper arm 411 may be integrally formed, and the second clamping member 422 and the second gripper arm 421 may also be integrally formed. In some other embodiments, only one of the first clamping member 412 and the second clamping member 422 may be adjustable.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The first clamping member 412 is movably mounted on the first gripper arm 411. The first gripper 41 includes a fixing member (not shown in the figure) for fixing the first clamping member 412 to the first gripper arm 411 after the first clamping member 412 is moved into place.

[0046] Regarding the adjustable position of the first clamping member 412, please refer to some specific embodiments. Figure 1 and Figure 2The first gripper arm 411 is provided with a gripper arm guide rail 4111, and the first clamping member 412 is provided with a guide groove adapted to the gripper arm guide rail 4111. The guide groove cooperates with the gripper arm guide rail 4111 to guide the first clamping member 412 to move along the extension direction of the first gripper arm 411 and adjust the distance between the first clamping member 412 and the second clamping member 422. The first gripper arm 411 is provided with a plurality of first fixing holes 4112 arranged at intervals along the length direction of the first gripper arm 411. After the position of the first clamping member 412 is adjusted into place, the fixing member passes through the first clamping member 412 and the first fixing holes 4112 to fix the first clamping member 412 to the first gripper arm 411. In some other embodiments, the first clamping member 412 and the first gripper arm 411 can also be fixed by other means, such as fixing by tightening with a set screw, fixing by snap-fitting with an elastic buckle, or fixing by magnetic attraction. In some other embodiments, the first gripper arm 411 may also be provided with a gripper arm guide groove, and the first clamping member 412 may be provided with a clamping member guide rail adapted to the gripper arm guide groove to guide the movement of the first clamping member 412.

[0047] Similarly, the position adjustment method of the second clamping member 422 can be the same as that of the first clamping member 412, and will not be described in detail here.

[0048] In some embodiments, please refer to Figure 1 and Figure 2 The first clamping member 412 includes a clamping block 4121 and a stop block 4122. The clamping block 4121 is fixed to the first gripper arm 411 and is used to contact and clamp the battery cell. The stop block 4122 is fixed to the clamping block 4121 and acts as a stop for the battery cell. To prevent damage to the battery cell, the clamping block 4121 is covered with an elastic material, such as EPDM rubber or silicone, which effectively prevents the gripper from damaging the battery cell when clamping it. For some embodiments, please refer to... Figure 1 and Figure 2 The stop block 4122 is U-shaped and has a U-shaped groove for holding the clamping block 4121. Specifically, in some embodiments, please refer to... Figure 1 and Figure 2 The stop block 4122 is fixed to the clamping block 4121 by fasteners.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 The clamping block 4121 is T-shaped and includes a first part 41211 connected to the first gripper arm 411 and a second part 41212 perpendicular to the first part 41211. The stop block 4122 is fixed on the second part.

[0050] Similarly, in some embodiments, please refer to Figure 1 and Figure 2 The second clamping member 422 can adopt the same structure as the first clamping member 412, and the details will not be elaborated further.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 The first clamping member 412 is detachably connected to the first gripper arm 411, and the second clamping member 422 is detachably connected to the second gripper arm 421. This allows both the first clamping member 412 and the second clamping member 422 to be removed. By replacing the first clamping member 412 and the second clamping member 422, different cell sizes can be accommodated, and maintenance of the clamping members is also convenient. Regarding the detachable connection method, any feasible method can be used, such as bolt connection, snap-fit, or magnetic fixation.

[0052] In some embodiments, please refer to Figure 1 and Figure 2 One of the first clamping member 412 and the second clamping member 422 is equipped with a photoelectric emitting module, and the other is equipped with a photoelectric receiving module. When there is a battery cell between the first clamping member 412 and the second clamping member 422, the photoelectric receiving module cannot receive the signal emitted by the photoelectric emitting module, thus sensing the absence of a battery cell. When there is no battery cell between the first clamping member 412 and the second clamping member 422, the photoelectric receiving module can receive the signal emitted by the photoelectric emitting module, thus sensing the absence of a battery cell in the gripper mechanism 4.

[0053] In some embodiments, please refer to Figure 1 and Figure 2 The rotary drive mechanism 3 includes a rotary drive motor 31, the lower end of which is fixed to the base 1, and a variable pitch base 21 is fixed to the upper end of the rotary drive motor 31. This reduces the space occupied by the rotary drive motor 31. In some other embodiments, the variable pitch base 21 can also be directly rotatably mounted on the base 1, and the drive motor drives the variable pitch base 21 to rotate through a gear system.

[0054] In some embodiments, please refer to Figure 1 and Figure 2 The rotary drive motor 31 is a direct drive motor, also known as a rotary DD motor. The rotary DD motor is a direct-drive brushless motor with zero backlash, high rigidity, and a large hollow inner diameter, effectively reducing wear on the air hoses and cables mounted on it due to rotation. Furthermore, the rotary DD motor enables high-precision rotary positioning.

[0055] For some examples of battery cell production line implementations, please refer to... Figure 3The battery cell production line includes a battery cell support and clamping mechanism 100 as described in any of the above embodiments, and further includes a first battery cell clamping mechanism 200 for transferring battery cell groups to the battery cell support and clamping mechanism 100 and a second battery cell clamping mechanism 300 for clamping battery cell groups from the battery cell support and clamping mechanism 100.

[0056] In some embodiments, please refer to Figure 3 Both the first cell clamping mechanism 200 and the second cell clamping mechanism 300 include at least two sets of cell clamping claws, wherein one set of cell clamping claws is used to clamp one cell. The distance between two adjacent sets of cell clamping claws in the first cell clamping mechanism 200 is less than or greater than the distance between two adjacent sets of cell clamping claws in the second cell clamping mechanism 300. That is to say, after the first cell clamping mechanism 200 transfers the cell group to the cell support and clamping mechanism 100, the cell support and clamping mechanism 100 needs to adjust the distance between adjacent cells in the cell group, reducing or increasing the distance between adjacent cells, so that the second cell clamping mechanism 300 can clamp the cell group on the cell support and clamping mechanism 100.

[0057] In some embodiments, please refer to Figure 3 The battery cell production line includes a first inspection station 400 and a second inspection station 500, with a battery cell support and clamping mechanism 100 located between the first inspection station 400 and the second inspection station 500. A first battery cell clamping mechanism 200 is used to transfer battery cell assemblies from the first inspection station 400 to the battery cell support and clamping mechanism 100, and a second battery cell clamping mechanism is used to clamp battery cell assemblies from the battery cell support and clamping mechanism 100 and transfer them to the second inspection station 500.

[0058] In some embodiments, please refer to Figure 3 The first inspection station 400 is for inspecting the edges and corners of the battery cell, and the second inspection station 500 is for inspecting the sides of the battery cell.

[0059] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
