Description

Technical Field

[0001] This invention relates to the field of fixtures for battery separation and capacity determination, and particularly to a sliding restraint tray. Background Technology

[0002] With the rapid development of rechargeable battery technology and the continuous expansion of its application fields, battery manufacturing processes are gradually moving towards higher efficiency and automation. In the battery production process, formation and settling are two key steps that significantly impact the stability and consistency of battery performance. The formation process refers to the initial activation of the chemically active materials within the battery, which is typically accompanied by the volume expansion of the battery casing. To ensure battery consistency and safety, effective dimensional constraints must be imposed on the batteries; therefore, using restraint trays to physically confine the batteries has become an indispensable part of production.

[0003] Restraint trays primarily constrain batteries by applying clamping force. However, for most restraint trays currently on the market, there is dry friction between the restraint end plate and the guide shaft on the tray, resulting in high frictional force. This requires workers to use considerable force to move the restraint end plate to complete the restraint and release operations, thus affecting the smoothness of restraint and release and significantly extending the entire battery processing cycle. Summary of the Invention

[0004] The purpose of this invention is to provide a sliding restraint tray that effectively reduces frictional resistance during restraint and release operations.

[0005] To achieve the above objectives, the present invention provides a sliding restraint tray, comprising a base plate, with a first end plate and a second end plate disposed opposite to each other at both ends of the base plate. The two sides of the first end plate and the second end plate are connected by two oppositely disposed guide shafts. A plurality of side plates are slidably connected to the guide shafts on both sides. A partition is also connected between each pair of opposite side plates on the guide shafts on both sides, and a filling space for filling material to be restrained is defined between two adjacent partitions. A pressing plate is also slidably connected to the end of the guide shafts on both sides near the first end plate. The pressing plate forms a pressing restraint or loosening operation on the partition based on the sliding on the guide shaft.

[0006] Preferably, the first end plate and the pressure plate are connected by a lead screw, which includes a first end and a second end. The first end is rotatably connected to the pressure plate, and the second end passes through the first end plate and is screwed to the first end plate. When the lead screw rotates, the second end moves in and out of the first end plate, and the first end rotates relative to the pressure plate.

[0007] Preferably, a handle is provided on each side of the clamping plate.

[0008] Preferably, a magnet is also provided on the inner side of each of the two handles on the clamping plate.

[0009] Preferably, adjacent side plates on the same guide shaft are connected by a movable interlocking structure.

[0010] Preferably, the engagement mechanism includes a first hook portion and a second hook portion that engage with each other, and there is an engagement gap between the first hook portion and the second hook portion.

[0011] Preferably, the bottom of the side plate is rotatably connected to the base plate via rollers.

[0012] Preferably, the side plate is connected to the guide shaft via a bushing.

[0013] Preferably, the partition plate has a plurality of pores.

[0014] Preferably, the base plate has a frame structure, and the pores penetrate the top and bottom of the partition.

[0015] Compared with existing technologies, the restraint tray provided by the present invention employs a design with guide shafts on both sides and slidingly connected side plates, partitions, and pressure plates, forming multiple independent filling spaces for fixing batteries. The clamping and releasing operations of each partition are completed by pushing / pulling the pressure plate along the guide shaft. Therefore, the restraint tray completes the restraint and releasing work through the sliding friction of the pressure plate and side plates relative to the guide shaft, thus avoiding the problems of sinking and increased resistance caused by traditional dry friction mechanisms. Only a smaller force is needed to complete the restraint and releasing work, facilitating improved work efficiency. Attached Figure Description

[0024] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] This invention discloses a restraint tray for battery separation and capacity reduction operations, which is used to load batteries to be processed.

[0026] like Figures 1 to 4 The restraint tray includes a base plate 10, with a first end plate 11 and a second end plate 12 disposed opposite to each other at both ends of the base plate 10. The two sides of the first end plate 11 and the second end plate 12 are connected by two oppositely disposed guide shafts 13. Specifically, to ensure the stability of the first end plate 11 and the second end plate 12, a guide shaft 13 is respectively disposed at the upper and lower ends of one side of the first end plate 11 and the second end plate 12.

[0027] Several side plates 14 are slidably connected to the guide shafts 13 on both sides. A partition 15 is connected between each pair of opposite side plates 14 on the guide shafts 13 on both sides. A filling space K for filling the material to be restrained is defined between two adjacent partitions 15. In this embodiment, the partition 15 is snapped into the two side plates 14 on both sides for easy assembly and disassembly.

[0028] A clamping plate 16 is slidably connected to one end of the guide shafts 13 on both sides near the first end plate 11. That is, the clamping plate 16 can slide along the guide shafts 13 on both sides. The clamping plate 16 forms a clamping or releasing operation on the partition 15 based on the sliding on the guide shafts 13.

[0029] In this embodiment, the clamping plate 16 is pushed manually or by machine to slide towards the second end plate 12 to complete the restraint of the battery BM. Conversely, the clamping plate 16 is pulled manually or by machine to slide towards the first end plate 11 to complete the release of the battery BM.

[0030] It is worth noting that, in Figure 1 In the middle, two rows of battery BM filling spaces K are provided between the first end plate 11 and the second end plate 12. These two rows of filling spaces K are independent of each other to improve the efficiency of the restraint tray. Figure 2In the middle, a row of battery BM filling space K is provided between the first end plate 11 and the second end plate 12.

[0031] On the other hand, please refer to the following: Figure 1 , Figure 2 and Figure 7 To facilitate restraint and release operations and support automation, a lead screw 2 connects the first end plate 11 and the pressure plate 16. The lead screw 2 includes a first end 20 and a second end 21. The first end 20 is rotatably connected to the pressure plate 16, and the second end 21 passes through the first end plate 11 and is screwed to it. When the lead screw 2 rotates, the second end 21 extends and retracts within the first end plate 11, while the first end 20 rotates relative to the pressure plate 16. For example, when the lead screw 2 is rotated forward using a wrench or motor, the length of the second end 21 extending beyond the first end plate 11 decreases, but the relative displacement between the first end 20 and the pressure plate 16 remains unchanged. Therefore, the first end 20 pushes the pressure plate 16 towards the second end plate 12, thereby performing the restraint operation. Conversely, when the screw 2 is rotated in the opposite direction by a wrench or motor, the length of the first end plate 11 extending from the second end 21 increases, thereby driving the clamping plate 16 to move toward the first end plate 11 via the first end 20 to perform the release operation.

[0032] A handle 3 is provided on each side of the clamping plate 16. In this embodiment, the two handles 3 on the clamping plate 16 can be operated by an external robotic arm to realize the push / pull operation of the clamping plate 16.

[0033] Furthermore, a magnet 4 is respectively provided on the inner side of the two handles 3 on the clamping plate 16. When the external robot arm is connected to the handle 3, the magnet 4 is attracted to the corresponding part of the robot arm to improve the stability of the connection between the robot arm and the handle 3.

[0034] On the other hand, such as Figure 4 The adjacent side plates 14 on the same guide shaft 13 are connected by a movable interlocking structure 5. Based on this interlocking structure 5, the adjacent side plates 14 are not only connected, but can also move relative to each other within a certain range. When the clamping plate 16 is pushed towards the second end plate 12, the clamping force is transmitted from the foremost side plate 14 to the last side plate 14, causing the multiple side plates 14 to abut tightly against each other. When the clamping plate 16 is pulled towards the first end plate 11, the clamping force on each side plate 14 disappears, and the distance between each side plate 14 can be adjusted to the maximum, thereby maximizing the distance of the filling space K to facilitate the installation of the battery BM.

[0035] Specifically, such as Figure 4 and Figure 5The biting mechanism 5 includes a first hook part 50 and a second hook part 51 that bite together, and there is a biting gap 52 between the first hook part 50 and the second hook part 51.

[0036] In this embodiment, as Figure 6 Each side plate 14 has a C-shaped groove at its front and rear ends, which serves as a first hook part 50 or a second hook part 51. The grooves of the two C-shaped grooves on the same side plate 14 are in opposite directions, so that the C-shaped grooves on the two adjacent side plates 14 are hooked together in opposite directions.

[0037] On the other hand, the bottom of the side plate 14 is connected to the bottom plate 10 by rollers 6, which can ensure the stability of the movement of the side plate 14 and reduce the frictional resistance between the side plate 14 and the bottom plate 10.

[0038] like Figure 5 The side plate 14 is connected to the guide shaft 13 through the bushing 16, thereby further reducing the sliding resistance between the side plate 14 and the guide shaft 13.

[0039] On the other hand, such as Figure 8 The separator 15 has several pores 150, which improves the heat insulation performance of the separator 15 and prevents the heat emitted by different batteries BM from affecting each other.

[0040] Furthermore, the base plate 10 has a frame structure, with pores 150 penetrating the top and bottom of the separator 15. In this embodiment, since the pores 150 penetrate the top and bottom of the separator 15, a convection structure is formed. Therefore, the heat generated by the battery BM is dissipated into the pores 150 of the separator 15 and can be quickly dissipated into the external environment. In addition, support platforms 151 are provided at the bottom of the front and rear sides of the separator 15. These support platforms 151 are used to support the battery BM to prevent the battery BM from being exposed from the filling space K.

[0041] This invention discloses a sliding restraint tray, which employs a design with guide shafts 13 on both sides and slidingly connected side plates 14, partitions 15, and a clamping plate 16, forming multiple independent filling spaces K for fixing batteries BM. The clamping and releasing operations of each partition 15 are completed by pushing / pulling the clamping plate 16 along the guide shaft 13. Therefore, the restraint tray completes the restraint and releasing work through the sliding friction of the clamping plate 16 and the side plates 14 relative to the guide shaft 13, thus avoiding the problems of sinking and increased resistance caused by traditional dry friction mechanisms. Only a small force is needed to complete the restraint and releasing work, facilitating improved work efficiency.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
