[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0049] This application provides a battery cell module tray; please refer to [link / reference]. Figure 1 , Figures 1 to 7 This is a schematic diagram of the structure of the battery cell module tray provided in an embodiment of this application.

[0050] The battery cell module tray 100 includes a tray base plate 1 and two support structures 2.

[0051] The pallet base 1 is the basic structure of the entire pallet, used to support and secure other components.

[0052] Both support structures 2 are mounted on the tray base plate 1, and the two support structures 2 are arranged opposite each other along the first direction. At least one support structure 2 is movably mounted on the tray base plate 1 along the first direction, and its position can be adjusted. Each support structure 2 is used to support one battery cell assembly (see...). Figure 2 Each cell group includes multiple cells 210 arranged along a second direction, which intersects the first direction, typically perpendicular or at an angle. When producing a single-row cell module 200, the two support structures 2 can be adjusted to a suitable distance so that each support structure 2 independently supports one cell group, forming two single-row cell modules 200. When producing a double-row cell module 200, the movable support structures 2 can be moved so that the two cell groups supported by the two support structures 2 can be combined into a double-row cell module 200 (as shown in the diagram). Figure 2 (As shown in the diagram). Whether it is a single-row cell module 200 or a double-row cell module 200, it can be adapted by adjusting the position of the support structure 2 to ensure that each cell group can be effectively supported.

[0053] In the technical solution of this application, each support structure 2 supports one battery cell group. At least one support structure 2 is movably disposed on the tray bottom plate 1 along a first direction. When producing single-row battery cell modules 200, the position of the movable support structure 2 is adjusted so that the two support structures 2 support two battery cell groups respectively, and each of these two battery cell groups forms a single-row battery cell module 200. That is, the two support structures 2 support two single-row battery cell modules 200 respectively to meet the support requirements of the two single-row battery cell modules 200. When switching to the production of double-row battery cell modules 200, the movable support structure 2 can be adjusted to a suitable position so that the two battery cell groups supported by the two support structures 2 combine to form a double-row battery cell module 200. In other words, two support structures 2 jointly support a double-row cell module 200 to meet the support requirements of a double-row cell module 200. This satisfies the mixed-line production requirements of single-row and double-row cell modules 200, improves the compatibility of the tray, and greatly reduces the time for adjusting the equipment during the changeover process and lowers labor costs compared to the traditional method of using dedicated trays or replacing parts to accommodate different modules. Specifically, by having each support structure 2 support a cell group and at least one support structure 2 movable along the first direction, the relative position of the two support structures 2 can be adjusted to meet the mixed-line production requirements of single-row and double-row cell modules 200, improve compatibility, and reduce changeover time and costs.

[0054] Understandably, during the production of a single-row cell module 200, adjusting the position of the movable support structure 2 allows each of the two support structures 2 to support two cell groups. This process essentially increases the distance between the two support structures 2 in the first direction, making the two cell groups independent and ensuring that the production of the two single-row cell modules 200 does not interfere with each other. However, when switching to the production of a double-row cell module 200, the movable support structure 2 can be adjusted to a suitable position, causing the two cell groups supported by the two support structures 2 to combine into a single double-row cell module 200. This involves bringing the distance between the two support structures 2 in the first direction closer, allowing the two cell groups to be combined into a single double-row cell module 200, which can then be processed as a whole.

[0055] Please see Figure 1In some embodiments, each support structure 2 includes a support base plate 21 and two end plates 22 connected to the support base plate 21; wherein, both support base plates 21 are disposed on the tray base plate 1, the two support base plates 21 are arranged opposite to each other along a first direction, and at least one support base plate 21 is movably disposed on the tray base plate 1 along the first direction; the two end plates 22 in each support structure 2 are arranged opposite to each other along a second direction, and at least one end plate 22 is movably connected to the support base plate 21 along the second direction, the two end plates 22 in each support structure 2 are used to clamp the battery cell assembly, and each support base plate 21 is used to support the battery cell assembly. In these embodiments, at least one support base plate 21 is movable in the first direction. When producing two single-row cell modules 200, the two support base plates 21 can be adjusted to a suitable distance so that each support structure 2 independently supports one cell group, thereby forming two single-row cell modules 200. When switching to producing a double-row cell module 200, by moving the movable support base plate 21, the relative position of the two cell groups in the first direction can be changed, so that they come closer and combine into a double-row cell module 200. It can be understood that when the dimensions of individual single-row cell modules 200 in the two single-row cell modules 200 are different in the first direction, by adjusting the two support base plates 21 to a suitable distance, the two support base plates 21 effectively support the two single-row cell modules 200 respectively, and the two single-row cell modules 200 do not interfere with each other, meeting the support requirements of single-row cell modules 200 with different dimensions in the first direction. When the dimensions of the double-row cell modules 200 are different in the first direction, they can also be adjusted to a suitable distance. Adjusting the two support base plates 21 to a suitable distance, the two support base plates 21 together effectively support a single double-row cell module 200, achieving the support requirements for double-row cell modules 200 of different sizes in the first direction. That is, by moving the movable support base plates 21, compatibility of cell modules 200 (including single-row cell modules 200 and double-row cell modules 200) of different sizes in the first direction can be achieved; at least one end plate 22 in each support structure 2 is movably disposed on the support base plate 21 along the second direction. This allows the relative position of the two end plates 22 in the second direction to be adjustable. Since the two end plates 22 in each support structure 2 are used to clamp the cell assembly, they can accommodate cell modules 200 of different sizes in the second direction (including single-row cell modules 200 and double-row cell modules 200). This not only satisfies the mixed-line production of single-row cell modules 200 and double-row cell modules 200, but also achieves compatibility with cell modules 200 of different sizes, further improving compatibility and reducing changeover time and cost.

[0056] Understandably, there are multiple ways to enable the support base plate 21 to move along the first direction on the pallet base plate 1. For example, the support base plate 21 can be connected to the pallet base plate 1 by a telescopic rod. The telescopic rod extends along the first direction, and the telescopic rod extends and retracts to drive the support base plate 21 to move along the first direction.

[0057] See Figure 1 and Figure 7 In some embodiments, the battery cell module tray 100 further includes a first guide rail 31 and a first slider 32. The first guide rail 31 is disposed on the tray base plate 1 and extends along a first direction; the first slider 32 is slidably disposed on the first guide rail 31 and is connected to a support base plate 21. Figure 7 In this embodiment, the first slider 32 is connected to the bottom surface of the support base plate 21 (the support base plate 21 is not shown in the figure to illustrate the structure of the first slider 32, etc.), so as to drive the support base plate 21 to move. In these embodiments, the sliding of the first slider 32 on the first guide rail 31 drives the support base plate 21 to move, so that the support base plate 21 can move in the first direction according to production needs (such as switching between single-row cell modules 200 and double-row cell modules 200, adapting to cell modules 200 of different sizes, etc.). The sliding of the first slider 32 along the first guide rail 31 can achieve a relatively smooth linear motion, which helps to improve the accuracy and stability of the support base plate 21 during movement, improve the changeover efficiency, and the combination of the first guide rail 31 and the first slider 32 has a relatively simple structure, intuitive design, is easy to manufacture and maintain, and reduces production and maintenance costs. Specifically, the first slider 32 can be driven by the first servo motor, and the rotational motion of the first servo motor can be converted into the linear motion of the first slider 32 through a transmission mechanism such as a lead screw, synchronous belt, gear, etc., so as to realize automated adjustment, reduce manual operation, and improve work efficiency.

[0058] See Figure 3 and Figure 6 In some embodiments, the battery module tray 100 further includes a pulling structure 11, which includes a connecting portion 111 and a force-bending portion 112 that is bent and connected to the connecting portion 111. The connecting portion 111 is connected to the support base plate 21, and the force-bending portion 112 can provide a point of force for operation, so as to pull the support base plate 21 through the pulling structure 11 to adjust the position of the support base plate 21. The force-bending portion 112 can be used for manual operation, or it can be used in conjunction with a matching force-applying mechanism to achieve automated operation, thereby enhancing the flexibility and adaptability of the system.

[0059] See Figure 7In some embodiments, the cell module tray 100 further includes a first slide rail lock 33, which is connected to a support base plate 21. The first slide rail lock 33 is disposed on the first guide rail 31 to restrict or allow the sliding of the corresponding first slider 32. In these embodiments, when it is necessary to adjust the position of the support base plate 21, the first slide rail lock 33 can allow the corresponding first slider 32 to slide. For example, when switching between a single-row cell module 200 and a double-row cell module 200, or when adapting to different sized cell modules 200, the restriction of the first slide rail lock 33 on the first slider 32 is released, allowing the support base plate 21 to move in the first direction as required. After the changeover is completed, the first slide rail lock 33 prevents the first slider 32 from moving, keeping the support base plate 21 stable and holding it in a specific position to ensure the normal assembly, processing, and other operational requirements of the cell module 200.

[0060] See you later Figure 7 In some embodiments, the first slide rail lock 33 includes a first lock seat 331 and a first lock body. The first lock seat 331 is provided with a first slot 3311. At least one inner sidewall of the first slot 3311 in the second direction is provided with a first receiving groove. The end of the first guide rail 31 facing away from the tray bottom plate 1 is inserted into the first slot 3311. The first lock body is disposed in the first receiving groove. The first lock body can move along the groove depth direction of the first receiving groove to have a locked position and an unlocked position. In the locked position, the first lock body is exposed in the first receiving groove and partially extends into the first slot 3311 to press the first guide rail 31. In the unlocked position, the first lock body is completely in the first receiving groove. In these embodiments, when the first lock body is in the unlocked position, it is completely in the first receiving groove. At this time, the first lock body no longer exerts a pressing effect on the first guide rail 31, and the first lock seat 331 can slide freely on the first guide rail 31, thereby allowing the first slider 32 to slide on the first guide rail 31. When the first lock body is in the locked position, it exposes the first receiving groove and partially extends into the first slot 3311. In this state, the first lock body can press the first guide rail 31, thereby restricting the sliding of the first slider 32 and achieving the locking effect, thereby ensuring that the position of the support base plate 21 remains unchanged. Specifically, the two inner sidewalls of the first slot 3311 in the second direction are provided with first receiving grooves. Correspondingly, there are two first lock bodies. The two first lock bodies can press the first guide rail 31 simultaneously from both sides to increase stability. More specifically, in order to control the movement of the first lock body, a first wedge block is provided between the first lock body and the bottom of the first receiving groove. The first wedge block is pushed by the first pneumatic piston. The first wedge block converts the thrust of the first pneumatic piston into two-way component forces through its inclined surface, thereby pushing the first lock body to move to the locked or unlocked position.

[0061] See Figure 4In some embodiments, the battery module tray 100 further includes a positioning structure 4, which includes multiple positioning parts 41 and positioning mating parts 42. The multiple positioning parts 41 are disposed on the tray base plate 1 along a first direction; the positioning mating parts 42 are disposed on a support base plate 21. When the support base plate 21 moves to different positions, the positioning mating parts 42 engage with different positioning parts 41 to restrict the movement of the support base plate 21. In these embodiments, it is understood that the positioning parts 41 can be grooves or holes, etc., and the positioning mating parts 42 can be protrusions or pins, etc. When it is necessary to adjust the position of the support base plate 21, the lock between the positioning mating parts 42 and the current positioning parts 41 is first released. Once unlocked, the support base plate 21 can move along the first direction to a new predetermined position. After reaching the target position, the positioning mating parts 42 engage with the new positioning parts 41 to relock the support base plate 21, ensuring that it remains stable. Specifically, the positioning parts 41 are positioning grooves, and the positioning mating parts 42 are positioning protrusions. Specifically, the position of the support structure 2 can be significantly adjusted (coarse adjustment) by sliding the first guide rail 31 and the first slider 32 over a wide range. The position of the support structure 2 can be fine-tuned by adjusting the positioning structure 4 over a small range. In this way, the large-range coarse adjustment can quickly adjust the initial position of the support structure 2, while the small-range fine adjustment can ensure the accuracy of the final position. Through this design that combines coarse and fine adjustment, the battery cell module tray 100 can not only achieve efficient changeover operations, but also ensure that the relative positions of the two support structures 2 are accurate, thereby improving the overall performance and reliability of the system.

[0062] See Figure 4In some embodiments, the battery module tray 100 further includes a first mounting block 5, a second mounting block 6, and an elastic member 7. The first mounting block 5 is disposed on the tray bottom plate 1, and a plurality of positioning parts 41 are disposed on the side of the first mounting block 5 facing the supporting bottom plate 21. The second mounting block 6 is disposed on the supporting bottom plate 21. The elastic member 7 is disposed between the second mounting block 6 and the positioning mating part 42 to drive the positioning mating part 42 to move from the second mounting block 6 toward the first mounting block 5. In these embodiments, the support base plate 21 is in a certain position, and the positioning mating part 42, under the action of the elastic member 7, engages with a positioning part 41 on the first mounting block 5, thereby fixing the position of the support base plate 21. When it is necessary to adjust the position of the support base plate 21, an external force is applied to overcome the elastic force of the elastic member 7, releasing the engagement between the positioning mating part 42 and the positioning part 41. After unlocking, the support base plate 21 can move along the first direction to a new predetermined position. After the support base plate 21 moves to the new position, the external force is removed, and the positioning mating part 42 automatically moves toward the first mounting block 5 under the drive of the elastic member 7 to achieve engagement with the new positioning part 41. The driving mechanism of the elastic member 7 can improve the stability of the support base plate 21 in the locked state, improve the safety of the system, and reduce the workload of the operator through the automatic reset function of the elastic member 7, making the adjustment process simpler and faster, and improving the changeover efficiency.

[0063] See Figure 1 and Figure 3 In some embodiments, the cell module tray 100 further includes a second guide rail 81 and a second slider 82. The second guide rail 81 is disposed on the support base plate 21 and extends along a second direction. The second slider 82 is slidably disposed on the second guide rail 81 and is connected to an end plate 22 to drive the end plate 22 to move. In these embodiments, the sliding of the second slider 82 on the second guide rail 81 drives the end plate 22 to move in the second direction, so that the end plate 22 can adapt to cell modules 200 of different sizes in the second direction. The sliding of the second slider 82 along the second guide rail 81 can achieve a relatively smooth linear motion, which helps to improve the accuracy and stability of the end plate 22 during movement, improve the changeover efficiency, and the combination of the second guide rail and the second slider 82 has a relatively simple structure, intuitive design, is easy to manufacture and maintain, and reduces production and maintenance costs. Specifically, the second slider 82 can be driven by the second servo motor. Through a transmission mechanism such as a lead screw, synchronous belt, or gear, the rotational motion of the second servo motor is converted into the linear motion of the second slider 82, thereby achieving automated adjustment, reducing manual operation, and improving work efficiency.

[0064] See Figure 3In some embodiments, the cell module tray 100 further includes a second slide rail lock 83, which is connected to an end plate 22 and is disposed on a second guide rail 81 to restrict or allow the sliding of the corresponding second slider 82. In these embodiments, when the position of the end plate 22 needs to be adjusted, the second slide rail lock 83 allows the corresponding second slider 82 to slide to accommodate cell modules 200 of different sizes in the second direction. When the second slide rail lock 83 restricts the second slider 82, the end plate 22 can move in the second direction as required. After the changeover is completed, the second slide rail lock 83 prevents the second slider 82 from moving, keeping the end plate 22 stable and achieving stable clamping of the cell module 200 to ensure the normal assembly, processing and other operation requirements of the cell module 200.

[0065] See Figure 3 In some embodiments, the second slide rail lock 83 includes a second lock seat 831 and a second lock body. The second lock seat 831 is provided with a second slot 8311. At least one inner sidewall of the second slot 8311 in the first direction is provided with a second receiving groove. One end of the second guide rail 81 away from the tray bottom plate 1 is inserted into the second slot 8311. The second lock body is disposed in the second receiving groove and can move along the groove depth direction of the second receiving groove to have a locked position and an unlocked position. In the locked position, the second lock body is exposed in the second receiving groove and partially extends into the second slot 8311 to press the second guide rail 81. In the unlocked position, the second lock body is completely in the second receiving groove. In these embodiments, when the second lock body is in the unlocked position, it is completely in the second receiving groove. At this time, the second lock body no longer exerts a pressing effect on the second guide rail 81, and the second lock seat 831 can slide freely on the second guide rail 81, thereby allowing the second slider 82 to slide on the second guide rail 81. When the second lock body is in the locked position, it exposes the second receiving groove and partially extends into the second slot 8311. In this state, the second lock body can press against the second guide rail 81, thereby restricting the sliding of the second slider 82 and achieving the locking effect, thereby ensuring that the position of the end plate 22 remains unchanged. Specifically, the two inner sidewalls of the second slot 8311 in the first direction are provided with second receiving grooves. Correspondingly, there are two second lock bodies. The two second lock bodies can press the second guide rail 81 simultaneously from both sides to increase stability. More specifically, in order to control the movement of the second lock body, a second wedge block is provided between the second lock body and the bottom of the second receiving groove. The second wedge block is pushed by the second pneumatic piston. The second wedge block converts the thrust of the second pneumatic piston into two-way component forces through its inclined surface, thereby pushing the second lock body to move to the locked or unlocked position.

[0066] See Figure 1In some embodiments, each support structure 2 further includes a support block 9, which is disposed on the support base plate 21 and extends along a second direction. Multiple support blocks 9 are provided, spaced apart along a first direction, with at least two support blocks 9 used to support the battery cell assembly. In these embodiments, using at least two support blocks 9 to support the battery cell assembly provides a stable support surface, ensuring uniform support for the battery cell assembly at multiple locations and avoiding deformation or damage caused by uneven local stress. The spaced arrangement of multiple support blocks 9 along the first direction allows a portion of the bottom of the battery cell module 200 to be suspended, facilitating the insertion of transfer tools (such as forklift inserts or robotic arms), improving transfer efficiency and convenience. Specifically, the support blocks 9 are made of insulating material. Since the support base plate 21 is typically made of metal, the insulating support blocks 9 prevent direct contact between the battery cell assembly and the metal base plate, reducing the risk of electrical short circuits and improving system safety. Specifically, each support structure 2 has three support blocks 9 spaced apart along the first direction. The middle support block 9 has a smaller size in the second direction. It can be understood that when the size of the battery cell assembly in the first direction is large, the three support blocks 9 support the battery cell assembly together. When the size of the battery cell assembly in the first direction is small, the middle support block 9 and one of the side support blocks 9 support the battery cell assembly together. Since the size of the battery cell assembly in the first direction is small, its size in the second direction is usually also small. Therefore, the size of the smaller middle support block 9 in the second direction is sufficient. This saves materials and helps reduce costs while fulfilling the support function.

[0067] See Figure 1 , Figure 3 and Figure 5 In some embodiments, each support structure 2 includes two end plates 22, each comprising a first end plate 221 and a second end plate 222. Both first end plates 221 are located at one end in a second direction, and both second end plates 222 are located at the other end in the second direction. Each first end plate 221 is movably connected to a corresponding support base plate 21 along the second direction. The cell module tray 100 also includes a connecting structure 10 extending along a first direction. One end of the connecting structure 10 is fixedly connected to one first end plate 221, and the other end of the connecting structure 10 is slidably connected to the other first end plate 221 along the first direction. In these embodiments, the connecting structure 10 ensures that the relative positions of the two first end plates 221 in the second direction remain consistent, allowing the two first end plates 221 to adjust their positions synchronously in the second direction, thereby increasing the adjustment speed and improving changeover efficiency.

[0068] See Figure 3 and Figure 6In some embodiments, the battery module tray 100 also includes a handle structure 12, which is disposed on the tray base plate 1. In these embodiments, the handle structure 12 allows the operator to easily lift and move the battery module tray 100, improving the convenience and efficiency of operation.
