Description

Technical Field

[0001] This utility model belongs to the field of battery pack repair equipment, and specifically relates to a mechanical device for disassembling battery packs. Background Technology

[0002] Battery packs are typically installed in electric vehicles, energy storage systems, and portable electronic devices using methods such as welding and gluing. When a battery pack needs repair, it must first be disassembled and removed for inspection. Currently, disassembly is mostly done manually, which makes it difficult to avoid electrical safety issues such as battery short circuits, and manual disassembly is inefficient. Even with disassembly machines, only welded parts can be cut and disassembled; the glued parts still need to be done manually, which remains time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a gantry-type battery pack disassembly and de-adhesion machine for new energy vehicles, which can disassemble both the adhesive joints and the welded parts.

[0004] A gantry-type battery pack de-welding and de-adhesive removal machine for new energy vehicles includes a gantry frame, a cutting head, and a three-axis moving mechanism. The cutting head can be equipped with a laser cutting head or a cutting tool and is mounted on the three-axis moving mechanism. The gantry frame includes a first column, a second column, and a crossbeam. The crossbeam is installed between the first column and the second column, and the three-axis moving mechanism is installed on the crossbeam.

[0005] A feeding mechanism is provided between the first column and the second column, and a lifting vehicle is provided along the feeding direction of the feeding mechanism.

[0006] Furthermore, the feeding mechanism includes a first roller row and a second roller row. The first roller row is installed at the bottom of the first column, and the second roller row is installed at the bottom of the second column. Two movable lifting vehicles are provided along the feeding direction. The first roller row, the second roller row, and the two lifting vehicles constitute a four-point support structure for the battery pack.

[0007] Furthermore, the lifting vehicle includes a lifting platform, a worm gear screw jack, and a frame. The worm gear screw jack is built into the frame. The input end of the worm gear screw jack is connected to a second handwheel. The output end of the worm gear screw jack is connected to the bottom of the lifting platform through a vertical drive shaft. The lifting platform is L-shaped, with its long side horizontal. The bottom of the lifting platform is slidably mounted on the frame through vertical guide columns. The bottom of the frame is equipped with rollers.

[0008] The second roller row is installed at the bottom of the second column via an extension plate, the extension plate being provided with a horizontal adjustment groove for fixing the second roller row.

[0009] A fixing block is provided above the first roller row. The fixing block is an inverted L-shape and has pressure teeth on one long side. A quick heavy-duty clamp is provided above the second roller row.

[0010] 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.

[0011] 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. The power head, heat exchange cylinder, and adsorption cylinder are installed sequentially along the same axis in the Z-axis direction. The heat exchange cylinder and adsorption cylinder cover the laser cutting head or cutting tool.

[0012] 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.

[0013] 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, the X-axis moving mechanism is mounted on the Y-axis moving mechanism, the Y-axis moving mechanism is mounted on the crossbeam, and the first column and the second column are both mounted on the crossbeam via a Z-axis lifting mechanism.

[0014] The beneficial effects of this utility model are as follows: Battery pack components are fed into the gantry via a feeding mechanism. A lifting trolley fixes both ends of the battery pack components and adjusts their height. The sides of the battery pack components are secured to quick-release heavy-duty clamps via fixing blocks. Then, a three-axis moving mechanism and a Z-axis lifting mechanism move the cutting head to the disassembly position to complete the disassembly process. Utilizing the lateral distance of the gantry and the longitudinal conveying distance of the feeding mechanism, the feeding and disassembly requirements of battery pack components with large length and width dimensions and large processing areas can be effectively met. Simultaneously, the cutting head can be selectively equipped with a laser cutting head to disassemble the bonded parts, or with cutting tools to disassemble the welded parts, thus achieving a composite processing of the two disassembly methods and improving disassembly efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1 , 2 As shown, the new energy vehicle gantry-type battery pack de-welding and de-adhesive removal machine includes a gantry frame A, a feeding mechanism B, a lifting vehicle C, a cutting head 4, and a three-axis moving mechanism D. The gantry frame A consists of a first column 13, a second column 14, and a crossbeam 2, with the crossbeam 2 positioned between the first column 13 and the second column 14. The first column 13 and the second column 14 have the same structure; the specific structure of both will be described below using the first column 13 as an example.

[0027] like Figure 5 , 6As shown, the crossbeam 2 consists of two branch pipes 10 arranged along the Y-axis. The first column 13 consists of a column pipe 11 and a sleeve 12. The sleeve 12 is fitted onto the column pipe 11 and is placed between the two branch pipes 10. The bottom of the column pipe 11 is fixed to the ground by a base plate 15 and anchor screws, and the top of the column pipe 11 is sealed by a cover plate 16 and screws. The Z-axis lifting mechanism 3 includes a first handwheel 18, a first Z-axis lead screw 19, and a first Z-axis nut 20. The first handwheel 18 is fixed to the cover plate 16 by an end cap 21 and screws. The cover plate 16, end cap 21, and handwheel 18 protrude from the fixing cover 9. The first handwheel 18 is powered to the first Z-axis lead screw 19, and the first Z-axis lead screw 19 is threaded to the first Z-axis nut 20. The first Z-axis nut 20 is tightened to a connecting shaft 22 along the X-axis. Both sides of the column tube 11 are provided with Z-direction sliding grooves 23. The connecting shaft 22 passes through the branch tube 10, the sleeve 12 and the Z-direction sliding grooves 23 in sequence along both sides of the column tube 11. Both ends of the connecting shaft 22 are fastened to the branch tube by round nuts 1.

[0028] like Figure 1 , 2 As shown, the first roller row 56 and the second roller row 57 constitute the feeding mechanism B. The first roller row 56 is fixed to the bottom of the column tube 11 of the first column 13 with screws. An inverted L-shaped fixing block 60 is provided on the upper outer side of the first roller row 56. The inner side of the long side of the fixing block 60 is provided with pressure teeth 61, which abut against one end face of the battery pack assembly E in the width direction. The thickness direction of the battery pack assembly E is vertically limited by the short side of the fixing block 60 and the transmission surface of the first roller row 56. The second roller row 57 extends from the bottom plate 15 of the second column 14 through the extension plate 17. The extension plate 17 is provided with a transverse adjustment groove 62 to adjust the installation position of the second roller row 57 according to the length in the width direction of the battery pack assembly E. The other end face in the width direction of the battery pack assembly E is fixed by a quick heavy-duty clamp 63, which is preferably a CH-30509M push-pull clamp. At the same time, the second roller row 57 is bolted and fixed through the adjustment groove 62.

[0029] like Figure 1 , 2As shown in Figures 7, 8, 9, and 10, the battery pack assembly E can be longitudinally transported along the first roller row 56 and the second roller row 57. Two lifting vehicles C are arranged in this transport direction, and the two lifting vehicles C have identical structures and are symmetrically arranged front and rear in this transport direction. Each lifting vehicle C includes a lifting platform 64, a worm gear screw jack 65, and a frame 66. The worm gear screw jack 65 is built into the frame 66. A second handwheel 67 connects to the input end of the worm gear screw jack 65. The output end of the worm gear screw jack 65 is connected to the bottom of the lifting platform 64 via a vertical drive shaft 68. The worm gear screw jack 65 is preferably a SWL1TP-2AⅢ-30 nut-lifting type worm gear screw jack. The lifting platform 64 is L-shaped, with its long side horizontal. The bottom of the lifting platform 64 is slidably mounted on the frame 66 via a vertical guide post 69. A roller 70 is provided at the bottom of the frame 66. The lifting vehicle C moves via roller 70 and limits the length of the battery pack assembly E via the short sides of the lifting platforms 64 of the two lifting vehicles C. By turning the second handwheel 67, the transmission shaft 68 and the lifting platform 64 are driven vertically by the worm gear screw jack 65, adjusting the vertical limiting position of the battery pack assembly E along the thickness direction. Thus, the four-point support planar limiting of the battery pack assembly E is achieved through the first roller row 56, the second roller row 57, and the two lifting vehicles C.

[0030] like Figure 1-10 As shown, by utilizing the lateral distance of the gantry A and the longitudinal conveying distance of the first roller row 56 and the second roller row 57, the feeding and disassembly requirements of the battery pack assembly E, which has a large distance in both length and width and a large processing area, can be effectively met. At the same time, by adjusting the Z-axis lifting mechanism 3 of the first column 13 and the second column 14 and loosening the round nut 1, the sleeve 12 can slide up and down relative to the column tube 11. By turning the first handwheel 18, under the screw transmission action 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 crossbeam 2 drives the three-axis moving mechanism D 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 pack assembly E.

[0031] like Figure 1-4As shown, the three-axis moving mechanism D 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 two branch pipes 10 of the crossbeam. 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 drive 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 drive mechanism. 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 drive mechanism.

[0032] Two branch pipes 10 are provided with a first baffle 33 on the inner side of the first column along the X-axis direction, and two branch pipes 10 are provided with a second baffle 34 on the inner side of the second column along the X-axis direction. 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. 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. 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.

[0033] 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.

[0034] 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.

[0035] like Figure 3 , 4As shown in Figures 9 and 10, the cutting head 4 includes a bracket 47, a mounting block 48, a power head 49, and an adsorption-cooled head 50. The power head 49 is fixed to the bracket 47 via the mounting block 48, and the mounting block 48 is fixed to the Z-axis nut 32 via the power plate 51. Both ends of the power plate 51 are mounted on the Z-axis guide rail 53 on the back plate 41 via Z-axis sliders 52. 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 via the heat exchange cylinder 58. The power head 49, the heat exchange cylinder 58, and the adsorption cylinder 59 are installed sequentially along the same axis in the Z-axis direction. The heat exchange cylinder 58 and the adsorption cylinder 59 cover the laser cutting head or cutting tool. When the battery pack assembly E is repaired and disassembled, cooling air is introduced into the air intake 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.

[0036] 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 adhesive parts of the battery pack, while the cutting tool, such as a milling cutter, is used to cut the welded parts of the battery pack, such as weld seams. Therefore, by simply changing the cutting tool, composite processing of both adhesive and welded parts can be achieved.
