Technical Field

[0001] This application relates to the field of battery transfer technology, and in particular to a battery cell transfer tray. Background Technology

[0002] During the battery manufacturing process, the battery cell needs to go through multiple processes such as liquid injection, pressurized immersion, high-voltage testing, and formation. For this, a battery cell transfer tray is needed to transfer and move the battery cell between different processes.

[0003] In existing technology, a battery cell transfer tray has a base plate with spaced clamps on the base plate. Battery cells are inserted between adjacent clamps to prevent them from tipping over. Limiting strips are provided at both ends of the clamps to contact the battery cells and prevent them from shifting. The positions of the clamps and limiting strips correspond to the battery cells to be transferred.

[0004] However, when transferring battery cells of different sizes, it is necessary to disassemble and assemble the clamps and limit strips accordingly to match the size of the battery cells, which makes the battery cell transfer tray less compatible. Utility Model Content

[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0062] In existing technology, a battery cell transfer tray has a base plate with spaced clamps on the base plate. Battery cells are inserted between adjacent clamps to prevent them from tipping over. Limiting strips are provided at both ends of the clamps to contact the battery cells and prevent them from shifting. To ensure the relative position of the battery cells remains stable during transfer, the positions of the clamps and limiting strips correspond to the battery cells to be transferred.

[0063] However, when transferring battery cells of different sizes, it is necessary to disassemble and assemble the clamps and limit strips accordingly to match the size of the battery cells, which makes the battery cell transfer tray less compatible.

[0064] Furthermore, when the number of battery cells to be transferred is small, the time required to disassemble and assemble the clamps and limit strips is short, which has a low impact on the efficiency of battery cell transfer. However, when the number of battery cells to be transferred is large, disassembling and assembling the clamps and limit strips is time-consuming and labor-intensive, affecting the efficient transfer of battery cells and leading to higher replacement costs.

[0065] To overcome the deficiencies in the prior art, the battery cell transfer tray provided in this application includes a support frame, a restraint assembly, and an adjustment drive assembly. The support frame has a receiving position, and the restraint assembly includes a first restraint member and a second restraint member disposed within the receiving position and forming a gap, the gap being able to accommodate a battery cell. The second restraint member is connected to the adjustment drive assembly. The first restraint member is movable along a first direction, and the second restraint member is movable along at least one of a second direction and a third direction under the drive of the adjustment drive assembly. Since the first, second, and third directions are perpendicular to each other, they can be aligned with the thickness, width, and length directions of the battery cell, thereby applying multi-directional constraints to the battery cell. Furthermore, since both the first and second restraint members are movable, when it is necessary to load battery cells of different sizes, the first and second restraint members can be moved to adapt to the battery cell size, thereby realizing the loading of battery cells of different sizes. Compared to existing cell transfer trays, which require complete disassembly and reassembly of various clamps and limiting strips to adapt to different cell sizes, the cell transfer tray of this application only requires the first and second restraint members to move to adapt to cells of different sizes. It does not require complete disassembly and reassembly, making the adjustment operation simpler and more efficient. It also provides a better fixation effect for the cells and effectively ensures compatibility with cells of different sizes.

[0066] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0067] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 As shown, this application embodiment provides a battery cell transfer tray, including:

[0068] Support frame 100, the support frame 100 is provided with receiving position 111;

[0069] The restraint assembly 200 includes a first restraint member 210 and a second restraint member 220 that are correspondingly and spaced apart within the receiving position 111. The space between the first restraint member 210 and the second restraint member 220 is used to receive the battery cell 500. The first restraint member 210 is used to apply a restraining force to the battery cell 500 in a first direction (X direction).

[0070] An adjustment drive assembly 300 is disposed on the support frame 100 and connected to the second restraint member 220 for driving the second restraint member 220 to apply a restraining force to the cell 500 along at least one of the second direction (Y direction) and the third direction (Z direction).

[0071] Figures 1 to 8 In the diagram, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction.

[0072] The support frame 100 serves as the foundation structure of the entire battery cell transfer tray, providing stable mounting support for other components. At least one receiving position 111 is formed on it to accommodate the restraint assembly 200, which clamps the battery cell 500, ensuring stability during the transfer of the battery cell 500. The support frame 100 includes a support plate 120 arranged along the YZ plane and a crossbeam 110 arranged along the X direction. The crossbeam 110 and the support plate 120 are interconnected to form a frame-like support frame 100 structure. Grooves are spaced along the X direction on the crossbeam 110 to form the receiving positions 111. The width of the grooves is adapted to at least one of the first restraint member 210 and the second restraint member 220.

[0073] The first restraint member 210 and the second restraint member 220 form a restraint assembly 200, wherein each first restraint member 210 is opposite to a second restraint member 220, and the two are disposed opposite each other within the receiving position 111, forming a gap between them for receiving the battery cell 500. The first restraint member 210 partially moves within the gap along a first direction (X direction). When the battery cell 500 is placed in the gap between the first restraint member 210 and the second restraint member 220, the first restraint member 210 can move along the X direction and contact the battery cell 500, thereby constraining the battery cell 500 in the first direction (X direction), that is, constraining the thickness direction of the battery cell 500.

[0074] Similarly, the second restraint 220 is connected to the adjustment drive assembly 300 and can move along at least one of the second direction (Y direction) and the third direction (Z direction) under the drive of the adjustment drive assembly 300. Combined with the constraint of the first restraint 210 in the first direction (X direction), since the first direction (X direction), the second direction (Y direction), and the third direction (Z direction) are perpendicular to each other, the movement of the second restraint 220 in the second direction (Y direction) and the third direction (Z direction) can apply constraints to the cell 500 in the width and length directions, thereby realizing multi-directional constraint on the cell 500, ensuring the relative position stability between the cell 500 and the restraint assembly, preventing the cell 500 from tipping over, tilting, or moving in multiple directions during transportation, and ensuring the safety and stability of the cell 500 transportation.

[0075] Furthermore, by adjusting the drive assembly 300, the adjustment operation of the second restraint member 220 becomes more convenient and efficient. By simply controlling the adjustment drive assembly 300, the second restraint member 220 can be partially moved to match the size of the battery cell 500 without requiring complete disassembly and assembly. In situations requiring frequent transfer of battery cells 500 of different sizes, and when dealing with a large number of cells 500, this saves significant time and labor costs, improving the overall efficiency of the battery cell 500 transfer process.

[0076] Therefore, the battery cell transfer tray provided in this application embodiment includes a support frame 100, a restraint assembly 200, and an adjustment drive assembly 300. The support frame has a receiving position 111. The restraint assembly 200 includes a first restraint member 210 and a second restraint member 220 disposed within the receiving position 111 and forming a gap. The gap can accommodate a battery cell 500. The second restraint member 220 is connected to the adjustment drive assembly 300. The first restraint member 210 can move along a first direction (X direction), and the second restraint member 220 can move along at least one of a second direction (Y direction) and a third direction (Z direction) under the drive of the adjustment drive assembly 300. Since the first direction (X direction), the second direction (Y direction), and the third direction (Z direction) are perpendicular to each other, they can correspond to the thickness, width, and length directions of the battery cell 500, thereby applying multi-directional constraints to the battery cell 500. Furthermore, since both the first restraint member 210 and the second restraint member 220 are movable, when it is necessary to load battery cells 500 of different sizes, the first restraint member 210 and the second restraint member 220 can be moved and adapted to the size of the battery cells 500, thereby realizing the loading of battery cells 500 of different sizes.

[0077] Compared to existing cell transfer trays, which require complete disassembly and reassembly of various clamps and limiting strips to adapt to different cell sizes, the cell transfer tray of this application only requires the first restraint member 210 and the second restraint member 220 to be movable to adapt to different sizes of cell 500. The operation is simpler and more efficient, and the fixing effect of the cell 500 is better, effectively ensuring compatibility with different sizes of cell 500.

[0078] In order to further improve the transfer capacity of the battery cell transfer tray, in some embodiments, reference is made to Figure 1 and Figure 2 As shown, multiple receiving positions 111 are arranged in at least two columns along the second direction (Y direction), and multiple receiving positions 111 in each column are arranged along the first direction (X direction).

[0079] This configuration, by arranging the accommodating positions 111 in at least two columns along the second direction (Y direction), with each column arranged along the first direction (X direction), fully utilizes the space of the support frame 100 in both the second (Y) and first (X) directions. Furthermore, by aligning the length direction of the battery cell 500 with the third (Z) direction, more accommodating positions 111 can be provided within the limited space of the support frame 100, thereby enabling the simultaneous carrying of more battery cells 500 and effectively improving the space utilization of the entire battery cell transfer tray. Compared to existing battery cell transfer trays, the battery cell transfer tray provided in this application can increase the capacity of battery cells 500 by more than four times.

[0080] Furthermore, refer to Figure 1 and Figure 2As shown, in order to achieve synchronous control of each second restraint member 220 in the same column, and synchronous control of at least two columns of second restraint members 220, and improve the size adjustment efficiency of the restraint assembly 200, the cell transfer tray also includes a connector 400. The connector 400 is connected to the adjustment block group 223 of each second restraint member 220 in the same column receiving position 111, and is connected to the adjustment drive assembly 300 so that the adjustment drive assembly 300 synchronously drives the adjustment block group 223 in the same column.

[0081] It is understandable that adjusting block groups 223 are set on the second restraint member 220 to restrain the battery cells 500 of different sizes. When the orientation of each second restraint member 220 is consistent, the relative positions of the adjusting block groups 223 on each second restraint member 220 are also consistent. This facilitates the connection of the corresponding adjusting block groups 223 at the same position via the connector 400, and the connection 400 is connected to the adjustment drive assembly 300. This allows the adjustment drive assembly 300 to synchronously control the corresponding adjusting block groups 223 via the connector 400. Only one operation of the adjustment drive assembly 300 is needed to move all adjusting block groups 223 in the same row synchronously, shortening the adjustment time and improving work efficiency. To ensure the consistency of the transmission of the connector 400, the connector 400 must be a rigid component.

[0082] Meanwhile, the connector 400 can ensure that the adjustment block groups 223 in the same row move in a consistent manner during the adjustment process, so that the second restraint members 220 in each receiving position 111 in the same row can move in the same way and with the same amplitude, ensuring the consistency of the constraint on the battery cells 500 in the same row, avoiding the problem that some battery cells 500 are not fixed firmly or are over-compressed due to inconsistent adjustment, and improving the accuracy and stability of fixing the battery cells 500.

[0083] In some embodiments, refer to Figure 1 and Figure 2 As shown, the adjustment drive assembly 300 is connected to the connectors 400 of at least two different columns to synchronously drive at least two columns of adjustment block groups 223.

[0084] By setting at least two connectors 400 to be connected to the adjustment block groups 223 located in different columns, and by connecting at least two adjustment block groups 223 to the same adjustment drive component 300, the adjustment efficiency of the adjustment drive component 300 can be further improved. Thus, by controlling a set of adjustment drive components 300, the active adjustment of at least two columns of adjustment block groups 223 can be achieved.

[0085] For example, in this embodiment, a total of four rows of receiving positions 111 are provided, and each pair of adjacent receiving positions 111 are connected to a set of adjustment drive components 300.

[0086] In some embodiments, at least two adjustment drive components 300 are provided, and the at least two adjustment drive components 300 are respectively located on opposite sides of the support frame 100 along the first direction (X direction) and connected to at least one identical connector 400.

[0087] It is understandable that when there are many positions 111 in a row, so that the length of the connector 400 is long, if the adjustment drive assembly 300 is only set on one side of the support frame 100, the part of the connector 400 near the other side of the support frame 100 is prone to jamming due to uneven force during the control of the connector 400, which affects the adjustment effect.

[0088] To address this, adjustment drive components 300 can be provided on both sides of the support frame 100, so that the adjustment drive components 300 on both sides are symmetrically distributed relative to the connector 400 along the first direction (X direction). When operating the adjustment drive components 300 on both sides, the adjustment drive components 300 need to be controlled synchronously to ensure that the corresponding connector 400 is subjected to uniform force and to prevent the connector 400 from jamming.

[0089] The structure of the restraint assembly 200 and the adjustment drive structure will be described below.

[0090] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the first restraint member 210 includes:

[0091] First plate 211, the first plate 211 is disposed in receiving position 111;

[0092] The telescopic part 212 is disposed on the side of the first plate 211 facing the gap. The telescopic part 212 extends and retracts along the first direction (X direction) to abut against the battery cell 500 and apply a restraining force along the first direction (X direction) to the battery cell 500.

[0093] The telescopic part 212 is disposed on the first plate 211 and extends and retracts along the first direction (X direction), which facilitates the first restraint member 210 to be flexibly adjusted according to the thickness of the battery cell 500, and changes the contact force with the battery cell 500 by extending and retracting, so that the first restraint member 210 and the battery cell 500 are in close contact.

[0094] Specifically, refer to Figure 7 As shown, the telescopic part 212 is an expansion bladder, which expands in the first direction (X direction) to apply a restraining force in the first direction (X direction) to the battery cell 500.

[0095] The first plate 211 has a double-layer clamping structure, with an opening on one of the clamping plates. This allows the telescopic part 212 to be clamped between the two clamping plates, with the telescopic part 212 exposed through the opening for easy extension and retraction. The telescopic part 212 is connected to a sealed gas pipeline, which is also clamped between the double-layer clamping plates to ensure its stability. This allows the gas pipeline to be sealed and connected to a gas control device, which can then supply gas to the telescopic part 212 through the gas pipeline to cause it to expand or draw in air to cause it to contract.

[0096] Furthermore, the expansion bladder is filled with gas, which has a high compressibility coefficient, providing flexible contact when the expansion bladder comes into contact with the battery cell 500. Compared to rigid restraint components, this avoids scratches, abrasions, and other damage to the surface of the battery cell 500, protecting the battery cell 500 from damage due to excessive pressure.

[0097] Furthermore, in some embodiments, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the second restraint member 220 includes:

[0098] The second plate 221 is disposed within the receiving position 111;

[0099] Fixing block 222, fixing block 222 is disposed on the side of the second plate 221 facing the gap;

[0100] Adjustment block group 223 is arranged at intervals relative to fixed block 222, and adjustment block group 223 is connected to adjustment drive assembly 300;

[0101] The adjustment drive assembly 300 adjusts the drive block group to move along a second direction (Y direction) and a third direction (Z direction) to apply a restraining force to the cell 500 along at least one of the second direction and the third direction.

[0102] The adjusting block assembly 223 moves along the first, second, and third directions (Z direction), thereby flexibly adjusting its relative position with the fixed block 222 to accommodate battery cells 500 of different lengths, widths, and thicknesses. Furthermore, the clamping stability of the battery cell 500 is ensured by the cooperation of the adjusting block assembly 223 and the fixed block 222. To ensure that the adjusting block assembly 223 and the fixed block 222 can stably clamp battery cells of different sizes, the minimum distance between the adjusting block assembly 223 and the fixed block 222 must be greater than or equal to the size of the smallest battery cell to be clamped, and the maximum distance between the adjusting block assembly 223 and the fixed block 222 must be greater than or equal to the size of the largest battery cell to be clamped.

[0103] For example, the fixing block 222 is fixedly disposed on the second plate 221, and the adjusting block group 223 can be slidably disposed on the second plate 221 via the guide rail.

[0104] It should be noted that, to improve the space utilization of the battery cell transfer tray, the width of the accommodating position 111 can be adapted to accommodate both a first plate 211 and a second plate 221 simultaneously. Specifically, the side of the first plate 211 with the telescopic portion 212 faces away from the second plate 221 within the same accommodating position 111 and towards the second plate 221 within an adjacent accommodating position 111, thus creating a gap between the first plate 211 and the second plate 221 in the other accommodating position 111 to accommodate the battery cell 500. Similarly, the side of the second plate 221 with the adjusting block assembly 223 faces away from the first plate 211 within the same accommodating position 111 and towards the first plate 211 in an adjacent further accommodating position 111, creating a gap between the second plate 221 and the second plate 221 in the further accommodating position 111 to accommodate the battery cell 500. That is, the two first restraint members 210 and the two second restraint members 220 only require three receiving positions 111 to form a space for two receiving cells 500.

[0105] In some embodiments, reference is made to Figure 8 As shown, the adjustment block group 223 includes:

[0106] The first adjusting block 2231 is spaced apart from the fixed block 222 along the second direction (Y direction) and moves along the second direction (Y direction) to apply a restraining force along the second direction (Y direction) to the cell 500.

[0107] The second adjusting block 2232 is spaced apart from the fixed block 222 along the third direction (Z direction) and moves along the third direction (Z direction) to apply a restraining force along the second direction (Y direction) to the cell 500.

[0108] The third adjusting block 2233 is spaced apart from the first adjusting block 2231 along the third direction (Z direction) and spaced apart from the second adjusting block 2232 along the second direction (Y direction). The third adjusting block 2233 moves along the second direction (Y direction) and the third direction (Z direction) to apply a restraining force along the second direction (Y direction) or the third direction (Z direction) to the cell 500.

[0109] The first direction (X direction), the second direction (Y direction), and the third direction (Z direction) are perpendicular to each other.

[0110] Three adjusting blocks constrain the battery cell 500 from different directions, forming a multi-directional clamping structure together with the fixing block 222. This effectively disperses the external forces experienced by the battery cell 500 during transport, reduces excessive local stress on the battery cell 500, and improves the stability and reliability of the battery cell 500. At the same time, the multi-directional constraint also enhances the synergistic effect between the adjusting block group 223 and the fixing block 222, making the entire structure of the second restraint member 220 more stable.

[0111] Specifically, the first adjusting block 2231 and the fixed block 222 are spaced apart, and corresponding guide surfaces are provided on the first adjusting block 2231 and the fixed block 222 to facilitate the insertion and removal of the battery cell 500 from this side. The first adjusting block 2231 moves along the second direction (Y direction) to realize the width adjustment of the battery cell 500.

[0112] The second adjusting block 2232 is disposed on one side of the fixed block 222 along the third direction (Z direction), and the second adjusting block 2232 and the fixed block 222 are both located on the same side of the first adjusting block 2231 along the second direction (Y direction), so that the second adjusting block 2232 can only move along the third direction (Z direction) to meet the height adjustment requirements of the cell 500, without moving along the second direction (Y direction), so that the second adjusting block 2232 and the fixed block 222 together form the width adjustment reference of the cell 500.

[0113] The third adjustment block 2233 is spaced apart from the first adjustment block 2231 along the third direction (Z direction) and from the second adjustment block 2232 along the second direction (Y direction), so that the third adjustment block 2233, the fixed block 222, the first adjustment block 2231 and the second adjustment block 2232 are distributed at four corners, so that the fixed block 222, the first adjustment block 2231 and the second adjustment block 2232 and the third adjustment block 2233 are connected in sequence to form a quadrilateral structure similar to a rectangle, and the third adjustment block 2233 simultaneously matches the width adjustment requirements of the first adjustment block 2231 and the height adjustment requirements of the second adjustment block 2232.

[0114] Furthermore, because the fixing block 222, the first adjusting block 2231, the second adjusting block 2232, and the third adjusting block 2233 are spaced apart from each other, while they jointly clamp the battery cell 500, a portion of the side of the battery cell 500 can still be exposed, forming ample operating space. This side portion can be equipped with structures such as the explosion-proof valve, injection hole, and electrode of the battery cell 500. Therefore, when each battery cell 500 is loaded in the battery cell transfer tray, the explosion-proof valve, injection hole, and electrode exposed on the support frame 100 can still be operated in batches, or processes such as injection, plugging, high-pressure impact, and pressure wetting can be performed without adjusting the position and angle of the battery cell 500. This makes the processing of the battery cell 500 more convenient and faster, and eliminates the need for additional handling or clamping devices in the above-mentioned processes, further expanding the applicability of the battery cell transfer tray.

[0115] It is understood that the second adjusting block 2232 moves along the third direction (Z direction) and aligns with the fixed block 222, thereby jointly abutting against the side of the battery cell 500 with the fixed block 222, thus applying a restraining force along the second direction (Y direction) to the battery cell 500. When the clamping direction of the third adjusting block 2233 on the battery cell 500 is different, the direction of the restraining force applied to the battery cell 500 is different. Specifically, when the third adjusting block 2233 moves to abut against the side wall of the battery cell 500, a restraining force along the second direction (Y direction) is applied to the battery cell 500, the direction of which is opposite to the direction of the restraining force applied by the third adjusting block 2233; while when the third adjusting block 2233 moves to abut against the bottom wall of the battery cell 500, a restraining force along the third direction (Z direction) is applied to the battery cell 500. The specific direction can be determined according to the battery cell size specifications and clamping requirements, and this application does not impose any restrictions on this.

[0116] Furthermore, refer to Figure 8 As shown, at least one of the first adjusting block 2231 and the third adjusting block 2233 is provided with a telescopic member 224, which extends and retracts along the second direction (Y direction).

[0117] It is understandable that after the first adjusting block 2231 and the third adjusting block 2233 are synchronously driven by the connector 400, the relative positions of each first adjusting block 2231 and each third adjusting block 2233 within the same row of receiving positions 111 remain consistent. When the dimensions of the battery cell 500 differ due to tolerances, it is difficult to guarantee that each battery cell 500 is subjected to stable restraint. Therefore, the elastic element can automatically extend and retract according to the actual width of the battery cell 500, thereby absorbing the tolerance of the battery cell 500 and achieving stable flexible clamping through adaptive adjustment, further improving the compatibility with battery cells 500 of different specifications. Specifically, the telescopic element 224 can be a helical spring, rubber block, resin block, etc., arranged along the second direction (Y direction).

[0118] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 As shown, to achieve the width adjustment of the first adjustment block 2231, the adjustment drive assembly 300 includes:

[0119] The first guide member 310 is disposed on the support frame 100 along the second direction (Y direction);

[0120] The first linkage 320 is slidably connected to the support frame 100 along the second direction (Y direction), the first linkage 320 is connected to the first guide 310, and the first linkage 320 is connected to the first adjusting block 2231.

[0121] The first linkage 320 drives the first adjusting block 2231 to move along the second direction (Y direction) via the first guide 310.

[0122] The first guide member 310 is arranged along the second direction (Y direction), specifically a lead screw. A first mating member 321 is threadedly connected to the first guide member 310. The first mating member 321 can be a clamping block with a threaded hole. The first mating member 321 is fixedly connected to the first linkage member 320. When the first guide member 310 rotates, the first mating member 321 can move along the first guide member 310 in the second direction (Y direction), and drive the first linkage member 320 to move synchronously. The two ends of the first linkage member 320 are respectively connected to at least two connecting members 400 in different columns. The connecting members 400 are further connected to the first adjusting blocks 2231 on each of the second restraint members 220 in their respective columns, thereby realizing the synchronous movement control of the first adjusting blocks 2231.

[0123] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 As shown, to achieve the width adjustment of the second adjustment block 2232, the adjustment drive assembly 300 further includes:

[0124] The second guide member 330 is disposed on the support frame 100 along the third direction (Z direction);

[0125] The second linkage 340 is slidably connected to the support frame 100 in the third direction (Z direction), the second linkage 340 is connected to the second guide 330, and the second linkage 340 is connected to the second adjusting block 2232.

[0126] The second linkage 340 drives the second adjusting block 2232 to move along the third direction (Z direction) via the second guide 330.

[0127] Similarly, the second guide member 330 can be a lead screw, and a slide rail 390 is provided on the support plate 120. A second mating member 341 is threadedly connected to the second guide member 330. Specifically, the second mating member 341 can be a slider that slides with the slide rail 390, and the second mating member 341 is threadedly connected to the second guide member 330. A second linkage member 340 is provided on the second mating member 341.

[0128] When the second guide member 330 rotates, the second mating member 341 can move along the second guide member 330 in the third direction (Z direction), and drive the second linkage member 340 to move synchronously. The two ends of the second linkage member 340 are respectively connected to at least two connecting members 400 in different columns. The connecting member 400 is further connected to the second adjusting block 2232 on each of the second restraint members 220 in its column, thereby realizing the synchronous movement control of the second adjusting block 2232.

[0129] Furthermore, in some embodiments, reference is made to Figure 1 , Figure 2 and Figure 5 As shown, to achieve the width adjustment of the third adjustment block 2233, the adjustment drive assembly 300 further includes:

[0130] The third guide member 350 is arranged on the support frame 100 along the third direction (Z direction);

[0131] The third linkage 360 ​​is slidably connected to the support frame 100 along the third direction (Z direction), and the third linkage 360 ​​is connected to the third guide 350;

[0132] The fourth guide member 370 is disposed on the third linkage member 360 along the second direction (Y direction);

[0133] The fourth linkage 380 is slidably connected to the third linkage 360 ​​along the second direction (Y direction), the fourth linkage 380 is connected to the fourth guide 370, and the fourth linkage 380 is connected to the third adjusting block 2233.

[0134] The third linkage 360 ​​drives the fourth linkage 380 to move via the third guide 350, thereby causing the fourth linkage 380 to drive the third adjusting block 2233 to move along the third direction (Z direction);

[0135] The fourth linkage 380 drives each of the third adjustment blocks 2233 to move along the second direction (Y direction) via the fourth guide 370.

[0136] Both the third guide member 350 and the fourth guide member 370 are lead screws. A third linkage member 360 is threadedly connected to the third guide member 350. The third linkage member 360 can also be configured as a slider structure and is slidably connected to the slide rail 390 on the support plate 120. A fourth guide member 370 is provided on the third linkage member 360, and a third mating member 381 is threadedly connected to the fourth guide member 370. The structure of the third mating member 381 is the same as that of the first mating member 321. The third mating member 381 is fixedly connected to the fourth linkage member 380, and the fourth linkage member 380 can slide relative to the support plate 120 in the second direction (Y direction). At least two connecting members 400 of different columns are connected to the fourth linkage member 380. The connecting members 400 are fixedly connected to each of the third adjusting blocks 2233 of the corresponding column.

[0137] Thus, when the third guide 350 rotates, the third linkage 360 ​​can synchronously drive the fourth guide 370, the third mating part 381, the fourth linkage 380 and the connecting part 400 to move along the third direction (Z direction), so that the connecting part 400 drives each third adjusting block 2233 to move along the third direction (Z direction).

[0138] When the fourth guide 370 rotates, the third mating part 381 can move along the fourth guide 370 in the second direction (Y direction) without changing the relative position of the third direction (Z direction), and drive the fourth linkage 380 to move synchronously, so that the connecting part 400 drives each third adjusting block 2233 to move in the third direction (Z direction).

[0139] The connector 400 can be bolted, riveted, welded, snapped, etc. with the corresponding first adjusting block 2231, second adjusting block 2232 and third adjusting block 2233, and this application does not limit this.

[0140] Furthermore, to avoid interference between the second adjusting block 2232 and the third adjusting block 2233, the portions of the second adjusting block 2232 and the third adjusting block 2233 that are connected to the connector 400 can be configured to form a height difference in the third direction (Z direction), so that the connector 400 connected to them is staggered in the third direction (Z direction), and the corresponding second linkage 340 and fourth linkage 380 are staggered.

[0141] For example, at least one of the first guide member 310, the second guide member 330, the third guide member 350 and the fourth guide member 370 is a lead screw.

[0142] In this embodiment, the first guide member 310, the second guide member 330, the third guide member 350 and the fourth guide member 370 are all lead screws, which provide smooth movement guidance for each linkage member and can directly drive each linkage member to move. After stopping rotation, each linkage member can be locked in the current position. The positioning reliability is good, and the load capacity is strong. It is easy to continuously apply stable constraint force. The structure is compact and the operation is simple.

[0143] In other embodiments, the lead screw can be replaced with a guide rod or other moving guide structure, and a corresponding bolt locking structure or snap-locking structure can be configured to prevent the position of the linkage from changing after it has moved into place.
