Technical Field

[0001] The utility model relates to the technical field of CTP battery cell boxing, in particular to a CTP battery cell boxing tool. Background Art

[0002] Currently, most CTP projects use a combination of machine grippers and sponge suction cups. The grippers clamp the tops of the cells together with the sponge suction cups, and the cells are then placed into the boxes in a step-by-step manner. This is exemplified by the Chinese invention patent application with publication number CN115676008A. However, the use of machine grippers and sponge suction requires certain equipment to work with the grippers. The grippers are complex, and the sponge suction cups have a high cycle and price. This results in high project costs and a long cycle, making it unsuitable for the R&D stage of CTP projects. Utility Model Content

[0003] The purpose of this utility model is to address the defects of the existing technology and provide a CTP battery cell boxing tooling, which is simple to operate, does not require any electrical control, and has a lower cost compared to the equipment suction cup gripper solution.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] like Figure 1 As shown, this embodiment provides a CTP battery cell boxing tool, including a pressing plate 1, a positioning mechanism, a side limit block 4, and an elastic pressing mechanism.

[0026] The pressing plate 1 is used to press on the top of the battery pack 13, and the lower surface of the pressing plate 1 is fixedly provided with a polyurethane pad 2, such as Figure 4 As shown, the battery pack 13 is prevented from being crushed.

[0027] The positioning mechanism is arranged on the pressure plate 1, and the positioning mechanism includes a positioning plate 11 and a positioning pin 12. The positioning plate 11 is fixed to the upper surface of the pressure plate 1 by screws, and the two ends of the positioning plate 11 extend out of the edge of the pressure plate 1. The positioning pin 12 is vertically arranged at the two ends of the positioning plate 11. One end of the positioning pin 12 passes downward through the positioning plate 11 and extends downward. The positioning pin 12 is used to cooperate with the positioning hole or threaded hole on the battery box to position the pressure plate 1, so as to facilitate the mechanical positioning of the entire tooling.

[0028] The side limit blocks 4 are arranged at both ends of the pressing plate 1 along the width direction, and the side limit blocks 4 are fixed to the side of the pressing plate 1 by screws, as shown in FIG. Figure 2 As shown, a guide surface 5 is provided at the bottom of the side limit block 4 close to the pressure plate 1. The guide surface 5 is an inclined plane or an arc surface. In this embodiment, the guide surface 5 is an arc surface. The thickness of the side limit block 4 at the guide surface 5 gradually decreases from top to bottom, so that the entire tooling can be buckled on the top of the battery pack 13. After being buckled on the top of the battery pack 13, the side limit block 4 can limit the two sides of the battery pack 13 in the width direction to prevent the independent battery cells from tilting.

[0029] An elastic clamping mechanism is arranged at both ends of the pressure plate 1 along its length. The elastic clamping mechanism includes a fixed block 6 and a lateral clamping block 7. The fixed block 6 is fixed to the upper surface of the pressure plate 1 by screws. The lateral clamping block 7 is arranged parallel to the fixed block 6 and elastically connected to the fixed block 6. A plurality of guide rods 9 are provided between the lateral clamping block 7 and the fixed block 6. One end of the guide rod 9 is fixedly connected to the fixed block 6, and the other end of the guide rod 9 is slidably connected to the lateral clamping block 7. The guide rods 9 are sleeved with springs. An adjustment member 8 is provided on the lateral clamping block 7. One end of the adjustment member 8 is threadedly connected to the fixed block 6 and is used to adjust the spacing between the lateral clamping block 7 and the fixed block 6. The lateral clamping block 7 is used to squeeze the battery pack 13. In this embodiment, the adjustment member 8 is a bolt. It can be understood that after the entire tool is buckled onto the battery pack 13, the top of the battery pack 13 can be clamped by rotating the adjusting piece 8 to move the lateral pressure block 7 toward the fixed block 6, so that the individual battery cells in the battery pack 13 are arranged in parallel, making it easier to completely press the battery pack 13 into the battery case through the pressure plate 1.

[0030] In order to prevent the elastic pressing mechanism from damaging the battery pack 13, a step is provided on the side of the lateral pressing block 7 close to the pressure plate 1. The step is arranged close to the bottom of the lateral pressing block 7. A gasket 10 is fixed on the step. The lateral pressing block 7 clamps the top of the battery pack 13 through the gasket 10.

[0031] A plurality of handles 3 are provided on the upper surface of the pressing plate 1 to facilitate manual pressing down and lifting of the entire tool.

[0032] In this embodiment, the length direction of the pressing plate 1 and the length direction of the battery pack 13 are both the thickness directions of the battery cells.

[0033] The usage of the CTP battery cell boxing tool is as follows:

[0034] After the battery pack 13 is placed in the battery case, the lower parts between the battery cells in the battery pack 13 will be squeezed tightly, and the upper parts between the battery cells will be in a trumpet shape. The tooling is lifted to the top of the battery pack 13 by the handle 3, and the two positioning pins 12 are inserted into the positioning holes or bolt holes on the battery case to position the entire tooling. The entire tooling is lowered so that the polyurethane pad 2 is placed on the top of the battery pack 13, and the two side limit blocks 4 are located on both sides of the upper part of the battery pack 13 to limit the battery pack 13 laterally. At this time, by rotating the adjusting piece 8, the side pressure block 7 is moved in the direction close to the fixed block 6, and the two side pressure blocks 7 can clamp the top of the battery pack 13 so that the battery cells in the battery pack 13 are arranged in parallel. At this time, by pressing down the pressing plate 1, the battery pack 13 can be completely pressed into the battery case. After the battery pack 13 is pressed into the battery case, the adjusting piece 8 is rotated again to move the side pressure block 7 in the direction away from the fixed block 6, and the positioning pins 12 are removed. At this time, the entire tooling can be lifted up to separate it from the battery pack 13.

[0035] Compared with the traditional equipment gripper + sponge suction cup method, this embodiment has the following advantages: 1. The cost of this tooling is low, and no expensive suction cups or equipment are required; 2. The processing cycle of this tooling is short, and it can be produced in a very short time, meeting the use of most project development cycles; 3. This tooling is simple to operate and can be used with any pressing tool (forklift, heavy iron block, pressing mechanism, etc.).

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
