Battery module repair and disassembly machine Technical Field

[0001] This utility model belongs to the field of battery module disassembly, and specifically relates to a disassembly device for battery module repair. Background Technology

[0002] Most different types of battery modules are installed using methods such as physical fixation with structural adhesive and electrical connections by welding. Battery module repair requires disassembly before repair. Based on the installation characteristics of battery modules, the structural adhesive and welded parts need to be disassembled separately. Manual disassembly is difficult to avoid electrical safety issues such as battery short circuits and is also inefficient. Although disassembly machines can cut and disassemble the welded parts, the removal of the structural adhesive still needs to be done manually. Summary of the Invention

[0003] The purpose of this invention is to provide a battery module repair and disassembly machine that achieves a composite processing of two disassembly methods: structural adhesive and welding.

[0004] The battery module repair and disassembly machine includes a main column, a rocker arm, a cutting head, and a three-axis moving mechanism. The rocker arm is supported on the main column, the cutting head can be equipped with a laser cutting head or a cutting tool, the cutting head is mounted on the three-axis moving mechanism, and the three-axis moving mechanism is mounted on the rocker arm.

[0005] The cutting head includes a power head, on which a laser cutting head or cutting tool is mounted along the Z-axis. An adsorption air-cooling head is provided along the laser cutting head or cutting tool. The adsorption air-cooling head is connected to an exhaust pipe through an air inlet pipe. Cooling air is input through the air inlet pipe, and an exhaust pipe is connected to an exhaust pump.

[0006] The adsorption air-cooling head includes a heat exchange cylinder and an adsorption cylinder. The air inlet pipe is connected to the exhaust pipe through the heat exchange cylinder.

[0007] A three-axis moving mechanism is installed at one end of the rocker arm, and a water tank is installed at the other end of the rocker arm. The main column is located in the middle section of the rocker arm, and the water tank and the power head form a circulating cooling circuit through pipelines.

[0008] Furthermore, the three-axis moving mechanism includes an X-axis moving mechanism, a Y-axis moving mechanism, and a Z-axis moving mechanism. The cutting head is mounted on the Z-axis moving mechanism, the Z-axis moving mechanism is mounted on the X-axis moving mechanism, and the X-axis moving mechanism is mounted on the Y-axis moving mechanism.

[0009] The aforementioned battery module repair and disassembly machine also includes a Z-axis lifting mechanism, which is a screw drive mechanism, and the rocker arm is mounted on the Z-axis lifting mechanism.

[0018] Figure 5 is a partial exploded view of the Z-axis lifting mechanism in Figure 4. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As shown in Figures 1 and 2, the battery module repair and disassembly machine includes a main column 1, a rocker arm 2, a Z-axis lifting mechanism 3, a cutting head 4, and a three-axis moving mechanism. The three-axis moving mechanism includes an X-axis moving mechanism 5, a Y-axis moving mechanism 6, and a Z-axis moving mechanism 7. The X-axis moving mechanism 5 and the Z-axis moving mechanism 7 are equipped with movable covers 8, and the Y-axis moving mechanism 6 is equipped with a fixed cover 9. The fixed cover 9 is mounted along the rocker arm 2. The three-axis moving mechanism is installed at one end of the rocker arm 2, and a water tank 56 is installed at the other end of the rocker arm 2. The main column is located in the middle of the rocker arm 2, close to the water tank 56. This installation structure uses the main column 1 as a fulcrum and the counterweight of the water tank 56 to achieve gravity balance with the three-axis moving mechanism, effectively reducing the vibration of the rocker arm 2 during processing by the three-axis moving mechanism and the cutting head 4, and improving the processing accuracy.

[0021] As shown in Figures 1, 2, 3, 4, and 5, the rocker arm 2 consists of two branch pipes 10 arranged along the Y-axis. The main column 1 consists of a column pipe 11 and a sleeve 12. The sleeve 12 is fitted onto the column pipe 11 and has a joint 13, which is secured at the joint 13 by a flange 14 and a locking wrench 57. The bottom of the column pipe 11 is fixed to the ground by a base plate 15 and anchor bolts, and the top of the column pipe 11 is sealed by a cover plate 16 and screws. The sleeve 12 is placed between the two branch pipes 10, and each branch pipe 10 is fixed to the sleeve 12 by a retaining clip 17 in both the upper and lower directions and by screws.

[0022] The Z-axis lifting mechanism 3 includes a handwheel 18, a first Z-axis lead screw 19, and a first Z-axis nut 20. The handwheel 18 is fixed to the cover plate 16 via an end cap 21 and screws. The cover plate 16, end cap 21, and handwheel 18 protrude from the fixed cover 9. The handwheel 18 is powered by the first Z-axis lead screw 19, which is threaded to the first Z-axis nut 20. The first Z-axis nut 20 is tightened along the X-axis direction by a connecting shaft 22. Both sides of the column tube 11 are provided with Z-axis sliding grooves 23. The connecting shaft 22 passes through the branch tube 10, the sleeve 12, and the Z-axis sliding grooves 23 sequentially along both sides of the column tube 11. Both ends of the connecting shaft 22 are tightened by hexagonal slotted nuts and pins.

[0023] When disassembling and repairing battery module A, the main column 1 is fixed to one side of the workbench on which battery module A is loaded. The main column 1 supports the rocker arm 2 to form a robotic arm. The cutting head 4 can be extended above the workbench on which battery module A is loaded by utilizing the length direction of the rocker arm 2. The rocker arm 2 moves up and down through the Z-axis lifting mechanism 3, so that the rocker arm 2 is like a robotic arm to complete the disassembly and processing. This rocker arm structure does not occupy processing space, simplifies the complex structure of processing workbench, fixtures and other components, and is easy to install.

[0024] Adjust the Z-axis lifting mechanism 3, turn the locking wrench 57, and loosen the flange 14 so that the sleeve 12 can slide up and down relative to the column tube 11. Turn the handwheel 18, and under the screw drive of the first Z-axis screw 19 and the first Z-axis nut 20, the first Z-axis nut 20 drives the connecting shaft 22 to move along the Z-axis. The connecting shaft 22 drives the sleeve 12 and the branch tube 10 to slide along the column tube 11 in the Z-axis direction. Thus, the rocker arm 2 drives the three-axis moving mechanism and the cutting head 4 to move up and down in the Z-axis direction, thereby adjusting the processing position of the cutting head 4 relative to the battery module.

[0025] As shown in Figures 1, 2, 3, 4, and 5, the X-axis moving mechanism 5 consists of an X-axis motor 24, an X-axis lead screw 25, and an X-axis nut 26 forming a lead screw transmission mechanism; the Y-axis moving mechanism 6 consists of a Y-axis motor 27, a Y-axis lead screw 28, and a Y-axis nut 29 forming a lead screw transmission mechanism; and the Z-axis moving mechanism 7 consists of a Z-axis motor 30, a Z-axis lead screw 31, and a Z-axis nut 32 forming a lead screw transmission mechanism.

[0026] The ends of the two branch pipes 10 are provided with a first baffle 33 along the X-axis, and the middle section of the two branch pipes 10 is provided with a second baffle 34 along the X-axis. A Y-axis motor 27 is mounted on the second baffle 34. The second baffle 34 is provided with a first proximity switch 35 for sensing the movement position in the Y-axis direction. The Y-axis motor 27 is powered by a Y-axis lead screw 28. The end of the Y-axis lead screw 28 is mounted on the first baffle 33, and the Y-axis lead screw 28 is mounted on a Y-axis nut 29. The Y-axis nut 29 is connected between the two branch pipes 10 by a U-shaped plate 36. A connecting plate 37 is provided on the back of the U-shaped plate 36, and the top of the U-shaped plate 36 is mounted on a Y-axis guide rail 39 on the branch pipe 10 by a Y-axis slider 38.

[0027] An X-axis motor 24 and a second proximity switch 40 for sensing X-axis movement are mounted on one side of the U-shaped plate 36. The X-axis motor 24 is powered by an X-axis lead screw 25, which is mounted on an X-axis nut 26. The end of the X-axis lead screw 25 is mounted on the other side of the U-shaped plate 36. The X-axis nut 26 is mounted on a back plate 41. A Z-axis motor 30 and a third proximity switch 43 for sensing Z-axis movement are mounted on a support plate 42 on the back plate 41. The Z-axis motor 30 is powered by a Z-axis lead screw 31, which is mounted on a Z-axis nut 32. The end of the Z-axis lead screw 31 is mounted on a base 44 on the back plate 41. The back plate 41 is mounted on an X-axis guide rail 46 on a connecting plate 37 via an X-axis slider 45.

[0028] The X-axis moving mechanism 5, Y-axis moving mechanism 6, and Z-axis moving mechanism 7 are controlled by a servo system. The X-axis motor 24 drives the X-axis lead screw 25 and X-axis nut 26 to drive the lead screw in the X-axis direction, the Y-axis motor 27 drives the Y-axis lead screw 28 and Y-axis nut 29 to drive the lead screw in the Y-axis direction, and the Z-axis motor 30 drives the Z-axis lead screw 31 and Z-axis nut 32 to drive the lead screw in the Z-axis direction, thereby realizing the tool setting process of the cutting head 4 along the three axes.

[0029] The cutting head 4 includes a bracket 47, a mounting block 48, a power head 49, and an adsorption air-cooling head 50. The power head 49 is fixed to the bracket 47 by the mounting block 48. The mounting block 48 is fixed to the Z-direction nut 32 by the power plate 51. The two ends of the power plate 51 are mounted on the Z-direction guide rail 53 on the back plate 41 by the Z-direction slider 52.

[0030] The power head 49 is a water-cooled inverter power head. The water tank 56 and the power head 49 form a circulating cooling loop via water pipes. A water pump pumps cooling water from the water tank 56 to the inverter's radiator. In the radiator, the cooling water exchanges heat with the heat generated inside the inverter, carrying away the heat and lowering the inverter's temperature. Simultaneously, the cooling water flows out of the radiator and returns to the water tank 56 through water pipes, forming a circulation.

[0031] The power head 49 can switch between mounting a laser cutting head and a cutting tool along the Z-axis. The laser cutting head is used to cut the structural adhesive of the battery module, while the cutting tool, such as a milling cutter, is used to cut the welded parts of the battery module, such as weld seams. Therefore, by simply changing the cutting tool, a composite processing method that involves disassembling both the structural adhesive and the welded parts can be achieved.

[0032] An adsorption-cooled head 50 is provided along the laser cutting head or cutting tool. The adsorption-cooled head 50 includes a heat exchange cylinder 58 and an adsorption cylinder 59. The air inlet pipe 54 is connected to the exhaust pipe 55 through the heat exchange cylinder 58. The power head 49, heat exchange cylinder 58, and adsorption cylinder 59 are installed sequentially along the same axis in the Z-axis direction. The heat exchange cylinder 58 and adsorption cylinder 59 cover the laser cutting head or cutting tool. When battery module A is repaired and disassembled, cooling air is introduced into the air inlet pipe 54, and the exhaust pump draws air from the exhaust pipe 55. The structural adhesive, welding slag, and other waste materials cut out are vacuum adsorbed by the adsorption cylinder 59. The heat generated by the laser cutting head or cutting tool during the cutting process is exchanged with the cooling air in the heat exchange cylinder 58 and discharged from the exhaust pipe 55 under the action of the exhaust pump, thereby achieving the purpose of cooling the laser cutting head or cutting tool.
