[0020] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0021] The present embodiment discloses a rechargeable battery capacity splitting restraint tray, which is a carrier of a battery body M in the capacity splitting process of the rechargeable battery production process.

[0022] like Figures 1 to 5 The restraint tray in this embodiment includes a frame 1, in which a plurality of partitions 2 are arranged at intervals, and the plurality of partitions 2 extend from one end of the frame 1 to the other end, and a receiving groove 3 for loading the battery body M is formed between two adjacent partitions 2. The partition 2 is detachably connected to the frame 1, and a heating element 4 and a temperature sensor 5 are arranged in the partition 2. An electric control board 6 is also arranged in the frame 1, and a driving power supply electrically connected to the heating element 4 on each partition 2 and a detection circuit electrically connected to the temperature sensor 5 on each partition 2 are arranged on the electric control board 6.

[0023] In the process of chemical division and capacity division, several battery bodies M to be processed are respectively loaded into each receiving groove 3 on the restraint tray, and then the driving power supply is started, and the heating element 4 starts to work, thereby heating the partition 2. At this time, since the two sides of the battery body M are respectively in contact with the partitions 2 on both sides of the receiving groove 3, the partition 2 directly transfers heat to the battery body M. Compared with the traditional heating method of thermal radiation, the heating method of heat conduction in this embodiment has a higher heating efficiency and minimizes heat loss. At the same time, the temperature sensor 5 detects the temperature on the partition 2 in real time, and the driving power supply dynamically adjusts the driving power of the heating element 4 according to the feedback of the temperature sensor 5, thereby realizing accurate temperature control of the external environment during the chemical division and capacity division of each battery body M. Furthermore, since the heating element 4 on the partition 2 is a consumable part, the detachable connection between the partition 2 and the frame 1 facilitates the disassembly and maintenance of the partition 2.

[0024] Furthermore, the partition plate 2 is connected to the frame body 1 by plugging and unplugging, and has a simple structure, is easy to implement, and is convenient to operate.

[0025] Specifically, a plurality of pairs of slide grooves 10 are arranged at intervals in the frame 1, and the slide grooves 10 extend upward from the bottom wall of the frame 1, and both ends of the partition 2 are slidably connected to the slide grooves 10. When assembling the restraint tray, a plurality of partitions 2 can be inserted into the corresponding pair of slide grooves 10, which effectively improves the assembly efficiency. When the partition 2 needs to be removed, the partition 2 can be pulled out of the slide groove 10.

[0026] On the other hand, the partition 2 is a rectangular thin plate, including two end walls 20 and two side walls 21. The partition 2 is connected to the frame 1 through the two end walls 20. When the battery body M is loaded into the receiving groove 3, the battery body M abuts against the side walls 21. A pair of sidewalls 22 are provided on the side walls 21 of the partition 2. The sidewalls 22 extend upward from the bottom of the partition 2. A limiting groove corresponding to the width of the battery body M is formed between the pair of sidewalls 22. A gap 11 is left between the outer side of the sidewall 22 and the inner wall of the receiving groove 3. An opening 12 is left between the two pairs of sidewalls 22 located on the two partitions 2 in the receiving groove 3.

[0027] In this embodiment, since there is a pair of sidewalls 22 on the two side walls 21 of the partition 2, each of the receiving grooves 3 has two pairs of sidewalls 22 arranged opposite to each other, that is, there are four sidewalls 22, and the four sidewalls 22 form a loading area, and the battery body M is loaded in the loading area during loading. In addition, since there is a gap 11 between the outer side of the sidewall 22 and the inner wall of the receiving groove 3, and there is an opening 12 between the two pairs of sidewalls 22 located on the two partitions 2 in the receiving groove 3, when loading and disassembling the battery body M, the worker's fingers or the gripper of the robot can hold the left and right sides of the battery body M through the pores 11 and the opening 12, thereby facilitating the loading and unloading of the battery body M.

[0028] Furthermore, the tops of the pair of side guard bars 22 are provided with bent portions 23 that are inclined in opposite directions to each other, so that the tops of the pair of side guard bars 22 form a bell-mouth structure, thereby facilitating the battery body M to enter the filling slot.

[0029] On the other hand, Figure 5 The partition 2 includes a support frame 24 and a heat conducting plate 25 disposed in the support frame 24, and the heating element 4 is arranged around the periphery of the heat conducting plate 25. In this embodiment, since the heating element 4 surrounds the periphery of the heat conducting plate 25, uniform heating of the heat conducting plate 25 is achieved, so that the temperature distribution of each part of the heat conducting plate 25 is uniform, so as to achieve uniform heating of each part of the battery body M.

[0030] Further, a temperature sensor 5 is respectively provided on the opposite sides of any heat conducting plate 25. In this embodiment, by providing two temperature sensors 5 on both sides of the heat conducting plate 25, the temperature on both sides of the heat conducting plate 25 can be respectively detected. In this way, the control circuit can comprehensively calculate the detection result according to the detection values ​​of the two temperature sensors 5. If it is found that the detection values ​​of the two temperature sensors 5 on any partition 2 are greatly different, it is possible that one of the temperature sensors 5 is abnormal, or one section of the heating element 4 is abnormal, then the partition 2 can be disassembled for maintenance. If the difference in the detection values ​​of the temperature sensors 5 on the partition 2 is within a preset range, the average value of the two temperature sensors 5 is used as the basis for controlling the driving power supply.

[0031] On the other hand, Figure 6 A power bus 7 electrically connected to the driving power supply is also provided in the frame 1, and the heating elements 4 on the plurality of partitions 2 are connected in parallel to the power bus 7 to prevent the operation of other heating elements 4 from being affected by damage to any one heating element 4.

[0032] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
