[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0036] The following is for reference. Figures 1-9 Description of a battery cell module disassembly device 100 according to an embodiment of the present utility model.

[0037] The battery cell module disassembly device 100 includes a frame 10 and a clamping mechanism 20. The frame 10 is provided with a disassembly position for placing the battery cell module. Placing the battery module in the disassembly position facilitates the clamping mechanism 20 in disassembling the battery module.

[0038] The battery cell module includes multiple battery cells stacked together and connected to each other by adhesive.

[0039] The clamping mechanism 20 includes a clamping assembly 22 and a flipping assembly 21. The clamping assembly 22 includes a gripper 221 and an adsorption member 222. The gripper 221 is used to clamp the outermost battery cell of the battery cell module, and the adsorption member 222 is used to adsorb the outermost battery cell of the battery cell module. Specifically, by controlling the opening and closing of the gripper 221, the outermost battery cell of the battery cell module is clamped. The adsorption member 222 can be connected to a vacuum device to make the adsorption member 222 a negative pressure state, thereby adsorbing the outermost battery cell of the battery cell module.

[0040] Specifically, there can be multiple grippers 221, which are spaced apart to improve the gripping reliability of the gripping component 22; there can also be multiple adsorption elements 222, which are respectively arranged on both sides of the multiple grippers 221. The adsorption elements 222 cooperate with the grippers 221 to achieve simultaneous adsorption and gripping, thereby improving the gripping efficiency.

[0041] The flipping component 21 is connected to the clamping component 22, and the flipping component 21 can drive the clamping component 22 to rotate. Specifically, the flipping component 21 and the clamping component 22 are connected by a transmission, and the flipping component 21 can drive the clamping component 22 to rotate so that the clamping component 22 rotates during the clamping of the battery cell. The clamping component 22 is used to disassemble the battery module.

[0042] In the existing technology, the clamp 221 is used to forcefully disassemble the two cells by tearing the adhesive between them. During the process of applying external force, it is easy to cause deformation of the cells or affect the surface quality of the cells. This is because the surface of the cells is covered with adhesive. If the adhesive is too tight, it is easy to damage the surface quality of the cells.

[0043] In this embodiment of the invention, during the rotation process, the clamping component 22 can move outward, rotating and pulling outward to tear the adhesive between multiple cells of the cell module, thus avoiding damage to the surface quality of the cells.

[0044] Therefore, this utility model achieves integrated suction and clamping by cooperating with the gripper 221 and the adsorption component 222; at the same time, by cooperating with the flipping component 21 and the clamping component 22, it can achieve rotation and outward pulling to tear open the adhesive between the battery cells, which can avoid deformation of the battery cells or affect the surface quality of the battery cells.

[0045] like Figure 2 As shown, the clamping mechanism 20 includes a reinforcing plate 23, a clamping assembly 22 mounted on the reinforcing plate 23, and a flipping assembly 21 including a first driving member. The first driving member is connected to the reinforcing plate 23 and is used to drive the reinforcing plate 23 to rotate. Specifically, the first driving member can be a flipping cylinder. Since the first driving member is connected to the reinforcing plate 23 and the clamping assembly 22 is mounted on the reinforcing plate 23, during the process of the first driving member driving the reinforcing plate 23 to rotate, the clamping assembly 22 rotates together with the reinforcing plate 23. While the adsorption member 222 adsorbs the outermost battery cell, the gripper 221 clamps the outermost battery cell. The first driving member drives the gripper 221 and the adsorption member 222 to rotate, tearing the adhesive between the battery cells by rotating and pulling outwards, which can avoid deformation of the battery cells or affecting the surface quality of the battery cells.

[0046] In some embodiments, the gripping assembly 22 includes a second driving member and a third driving member. The second driving member is connected to the gripper 221 to drive the pneumatic gripper to open and close, and the third driving member is connected to the adsorption member 222 to drive the adsorption member 222 to adsorb the outermost battery cell of the battery cell module. Specifically, the second driving member is tractively connected to the gripper 221 and is used to drive the gripper 221 to open and close, thereby causing the gripper 221 to grip the outermost battery cell. The third driving member is tractively connected to the adsorption member 222, thereby causing the adsorption member 222 to adsorb the outermost battery cell. Furthermore, the second and third driving members operate synchronously so that the gripper 221 and the adsorption member 222 simultaneously grip and adsorb the battery cell, thereby improving the disassembly efficiency of the battery cell module.

[0047] like Figure 1As shown, the cell module disassembly device 100 further includes a drive mechanism 30, which is connected to the clamping mechanism 20. The drive mechanism 30 is used to drive the clamping mechanism 20 to move. Specifically, the drive mechanism 30 is connected to the clamping mechanism 20 in a transmission manner. The drive mechanism 30 is used to drive the clamping mechanism 20 to move to the disassembly position so that the clamping mechanism 20 can disassemble the outermost cell. After the outermost cell is disassembled, the drive mechanism 30 drives the clamping mechanism 20 to transport the disassembled cell to the next station. Then, the drive mechanism 30 drives the clamping mechanism 20 to disassemble the next cell, and so on.

[0048] In some embodiments, the drive mechanism 30 can be an execution robot connected to the gripping mechanism 20, and the execution robot is used to drive the gripping mechanism 20 to move. Specifically, the execution robot includes a robotic arm, and the gripping mechanism 20 is mounted on the robotic arm at the end of the execution robot. The execution robot is used to drive the gripping mechanism 20 to move to the disassembly position to grip the battery cell, or to move from the disassembly position to a designated position and place the disassembled battery cell in the designated position. By replacing manual labor with an execution robot, the disassembly yield of battery packs is improved, and the disassembly difficulty and labor intensity are reduced.

[0049] Furthermore, the execution robot includes a flange, and the gripping mechanism 20 is connected to the flange, thereby connecting the gripping mechanism 20 and the execution robot as a whole.

[0050] The robotic arm comprises multiple axes, each equipped with a high-precision sensor and actuator. Its design fully considers ergonomic principles, resulting in a wide range of motion, flexible operation, and adaptability to various complex working environments. Each axis of the robotic arm can be made of precision-machined metal materials, possessing excellent wear resistance and corrosion resistance.

[0051] Combination Figures 1-5 As shown, the battery cell module disassembly device 100 further includes a restraint mechanism located at the disassembly position and connected to the frame 10. The restraint mechanism is used to restrain the battery cell module along a first direction. Specifically, the restraint mechanism is connected to the frame 10, the stacking direction of the multiple battery cells of the battery cell module is consistent with the first direction, the restraint mechanism extends along the first direction, and the restraint mechanism restrains the battery cell module in the first direction. After the battery cell module is placed at the disassembly position, the restraint mechanism restrains the battery cell module. When the clamping mechanism 20 moves to face the outermost battery cell, the restraint mechanism releases the restraint on the outermost battery cell module, making it easier for the clamping mechanism 20 to clamp the outermost battery cell.

[0052] like Figure 1As shown, the restraint mechanism includes a first clamping assembly 41 and a second clamping assembly 42. The first clamping assembly 41 and the second clamping assembly 42 are spaced apart along a first direction and respectively abut against both sides of the battery cell module in the stacking direction. The first clamping assembly 41 is connected to the frame 10, and the second clamping assembly 42 is movable along the first direction. That is, the first clamping assembly 41 is located on one side of the battery cell module in the first direction, restraining the innermost side of the battery cell module, and the second clamping assembly 42 is located on the other side of the battery cell module in the first direction, selectively abutting against the outermost side of the battery cell module.

[0053] After the battery cell module is placed in the disassembly position, the first clamping component 41 abuts against one side of the battery cell module, and the second clamping component 42 abuts against the other side of the battery cell module to restrain the battery cell module; when the clamping mechanism 20 moves to be opposite to the outermost battery cell, the second clamping component 42 moves along the first direction toward the side away from the battery cell module, so that the clamping mechanism 20 can disassemble the outermost battery cell.

[0054] like Figure 4 As shown, the first clamping assembly 41 includes a lead screw assembly 411 and a clamping member 412. The lead screw assembly 411 includes a base 413, a mounting base 414, a nut 415 and a lead screw 416. The base 413 is connected to the frame 10. The lead screw 416 is fixed in the mounting base 414. The mounting base 414 is connected to the base 413. The clamping member 412 is connected to the lead screw 416. By adjusting the lead screw 416 to drive the nut 415 to move, the clamping member 412 is driven to move along the first direction to achieve the restraint and positioning of one side of the battery cell module.

[0055] like Figure 3 As shown, the second clamping assembly 42 includes two clamping assemblies 421, which are spaced apart along the second direction. The two clamping assemblies 421 respectively restrain both ends of the battery cell in the length direction. The clamping assembly 421 includes a restraining cylinder 422, which can move along the first direction to restrain the outside of the battery cell module.

[0056] Furthermore, the restraint mechanism also includes: a fixed frame 43, which extends along a first direction and is connected to the frame 10; a clamping assembly 421 is movably connected to the fixed frame 43 and is movable relative to the fixed frame 43 along the first direction. Specifically, there are two fixed frames 43, and two clamping assemblies 421 are respectively mounted on the two fixed frames 43. One side of the fixed frame 43 in the first direction is connected to the first clamping assembly 41, and the clamping assembly 421 is located on the other side of the fixed plate in the first direction. The clamping assembly 421 can be mounted on the fixed frame 43 to realize the installation of the clamping assembly 421. Specifically, the restraint cylinder 422 is movable relative to the fixed frame 43 along the first direction. After the battery cell module is placed in the disassembly position, the restraint cylinder 422 moves along the first direction to abut against the other side of the battery cell module; when the clamping mechanism 20 moves to be opposite to the outermost battery cell, the restraint cylinder 422 moves along the fixing frame 43 to the side away from the battery cell module to release the restraint on the battery cell module.

[0057] like Figure 3 As shown, the clamping assembly 421 includes a mounting plate 423 and a restraint cylinder 422. The restraint cylinder 422 is mounted on the fixed frame 43 via the mounting plate 423. The restraint cylinder 422 can move in a first direction. The mounting plate 423 is slidably mounted on the fixed frame 43, so the mounting plate 423 can move along the first direction with the restraint cylinder 422.

[0058] like Figure 1 As shown, the battery cell module disassembly device 100 further includes two step mechanisms 50, which are spaced apart along a second direction and connected to the frame 10. The two step mechanisms 50 clamp the two outermost battery cells in the battery cell module at both ends along their length. Specifically, the step mechanisms 50 are connected to the frame 10 via a linear motor assembly 60. The two step mechanisms 50 are spaced apart along the second direction. After the battery cell module is placed in the disassembly position, the restraint mechanism first restrains the battery cell module. Then, the two step mechanisms 50 clamp the battery cell module on both sides in the second direction, and any step mechanism 50 can clamp the two outermost battery cells. When the clamping mechanism 20 moves to the disassembly position, the step structure moves along a first direction and clamps the second and third outermost battery cells, facilitating the clamping mechanism 20 to clamp the outermost battery cells and preparing for the clamping mechanism 20 to clamp the second battery cell.

[0059] Combination Figure 1 , Figure 6 and Figure 7As shown, there are two linear motor assemblies 60, each connected to one of the two stepping mechanisms 50. Each linear motor assembly 60 includes: a linear motor 61, a guide rail assembly 62, a crossbeam 63, a connecting plate 64, a guide rail mounting strip 65, a cable chain 66, and a cable chain support plate 67. The linear motor 61 is fixed to the crossbeam 63, and the guide rail assembly 62 is located below the linear motor 61, working together to complete the loading and unloading of the battery cells. The connecting plate 64 is fixed below the crossbeam 63, and together with all other components, is fixed to the battery cell loading and unloading platform.

[0060] like Figure 8 and Figure 9 As shown, the stepping mechanism 50 includes a first stepping member 51 and a second stepping member 52. The first stepping member 51 and the second stepping member 52 are spaced apart along a first direction and respectively clamp the two outermost battery cells of the battery cell module. Specifically, when the stepping mechanism 50 clamps the battery cell module on one side of the second direction, the first stepping member 51 clamps the first outermost battery cell, and the second stepping member 52 clamps the second outermost battery cell. After completing the current battery cell gripping process, it moves backward again to the next battery cell to complete the clamping, and continues to complete the gripping of other battery cells.

[0061] like Figure 9 As shown, the stepping mechanism 50 also includes: a positioning component 53, a pneumatic slide table 54, and a slide table cylinder 55. There are two pneumatic slide tables 54, which are respectively connected to the first component and the second stepping component 52. Both pneumatic slide tables 54 are connected to the slide table cylinder 55 for transmission. The slide table cylinder 55 drives the two pneumatic slide tables 54 to move. The positioning component 53 is connected to the first stepping component 51 and moves synchronously. The centering and clamping are completed by the slide table cylinder 55. The first stepping component 51 and the second stepping component 52 are respectively pressed by the two pneumatic slide tables 54 to clamp the battery cell that needs to be grabbed and the battery cell behind it, so that the clamping mechanism 20 can disassemble the battery cell module.
