Example

[0025] like Figures 1 to 9 As shown, this embodiment discloses a battery pack peeling machine for passenger vehicles, including a frame 1, on which a peeling mechanism is rotatably connected; the peeling mechanism includes a wrapping assembly 2 and a plurality of clamping assemblies 3, the wrapping assembly 2 is rotatably connected to the frame 1, and the plurality of clamping assemblies 3 are sequentially arranged inside the wrapping assembly 2 and perform clamping and fixing operations on the end of the battery pack outer skin 71 that extends into the wrapping assembly 2. The rolling assembly 2 includes a horizontally arranged roller 21, the two ends of which are rotatably connected to the frame 1. The circumferential sidewall of the roller 21 is provided with an insertion port 211 for the end of the battery pack outer sheath 71 to extend into. The length direction of the insertion port 211 is consistent with the axial direction of the roller 21. Several clamping assemblies 3 are equally spaced inside the roller 21 along the axial direction of the roller 21. The clamping assemblies 3 are fixedly connected to the circumferential sidewall of the roller 21 and clamp and fix the end of the battery pack outer sheath 71 extending from the insertion port 211.

[0026] The rolling assembly 2 also includes a first flange 22 and a second flange 23 symmetrically fixed at both ends of the roller 21. The first flange 22 and the second flange 23 are both fixedly connected to the roller 21. A power assembly 5 is provided on the outside of the first flange 22 and drives the roller 21 to rotate automatically. A control assembly 6 is provided on the outside of the second flange 23 and controls the clamping state of the rolling assembly 3.

[0027] The frame 1 is arranged on both sides of the roller 21 along the axial direction. The bottom end of the frame 1 is connected to a traveling wheel 102 for easy movement. The rear end of the frame 1 is fixedly connected to a push rod 101, which pushes the frame 1 and the peeling mechanism to move. A lifting mechanism 4 is provided between the frame 1 and the roller 21, and the height of the roller 21 is adjusted by the lifting mechanism 4.

[0028] The lifting mechanism 4 includes a positioning rod 41 and a lead screw assembly. The positioning rod 41 is positioned above the drum 21 and fixedly connected to the frame 1. The length direction of the positioning rod 41 is consistent with the axial direction of the drum 21. Two sets of lead screw assemblies are provided, and the two sets of lead screw assemblies are respectively located on both sides of the axial direction of the drum 21. The lead screw assembly is connected to the positioning rod 41. The lead screw assembly includes a lead screw 42, a turntable 43, and a pull ring 44. The turntable 43 has a through screw hole at its center and is threaded to the outer periphery of the top of the lead screw 42 through the through screw hole. The bottom end of the lead screw 42 passes through the limiting hole provided on the positioning rod 41 and is connected to the top pin of the pull ring 44. The pull ring 44 is an open ring and is sleeved on the outer circumference of the drum 21. Two rolling pulleys 45 are symmetrically arranged on the inner side of the bottom end of the pull ring 44. The outer periphery of the two rolling pulleys 45 contacts the bottom of the outer periphery of the drum 21 and suspends and supports the drum 21 to reduce the friction when the drum 21 rotates.

[0029] In the design, the roller is suspended on the frame by a lifting mechanism. By rotating the turntable, the pull ring and the roller can be moved up and down under the action of the lead screw, thereby adjusting the height of the roller. The height of the roller can be adjusted adaptively according to the height of the battery pack to improve the versatility of the invention.

[0030] The power assembly 5 includes a movable frame 51, a power motor 53, a reducer 54, a transmission gear 57, and a reduction gear 55. The power motor 53 and the reducer 54 are both fixedly connected to the movable frame 51, and the power motor 53 and the reducer 54 are connected in a transmission connection. The reduction gear 55 is connected to the output shaft of the reducer 54. The transmission gear 57 is coaxially arranged with the first flange 22 and is fixedly connected to the outer wall of the first flange 22. The transmission gear 57 is rotatably connected to the movable frame 51 through a gear shaft 56, and the transmission gear 57 is meshed with the reduction gear 55. A movable wheel 52 is rotatably connected to the bottom of one end of the movable frame 51. Under the gravity of the power motor 53 and the movable frame 51, the movable wheel 52 contacts the top end face of the battery pack 7, which is undergoing the peeling operation, so that the battery pack 7 supports the movable frame 51 and the power motor 53.

[0031] This invention controls the rotation of a roller and a clamping assembly inside the roller via a power component, thereby curling the torn battery casing onto the outer circumference of the roller to remove the battery casing. As the roller rotates, the entire peeling machine moves automatically on or to the sides of the battery pack under the action of movable and traveling wheels, thus achieving automatic peeling of the battery casing. No manual pushing of the peeling machine is required during the peeling process, improving the efficiency of the peeling machine.

[0032] The clamping assembly 3 includes two symmetrically arranged mounting plates 31, a movable clamping piece 33 disposed between the two mounting plates 31, and a fixed clamping piece 34 disposed between the two mounting plates 31. The outer edge of the mounting plate 31 is provided with a mounting protrusion 311, which is engaged and fixed with the mounting groove 212 disposed on the circumferential side wall of the roller 21. The fixed clamping piece 34 is fixedly connected to the mounting plate 31. The movable clamping piece 33 is located below the fixed clamping piece 34 and is L-shaped. The middle part of the movable clamping piece 33 is connected to the mounting plate 31 by a pin. One end of the movable clamping piece 33 is connected to the mounting plate 31 by a tension spring 32, and the other end of the movable clamping piece 33 abuts against the bottom end of the fixed clamping piece 34 under the tension of the tension spring 32. The abutment position between the movable clamping piece 33 and the fixed clamping piece 34 corresponds to the insertion port 211 on the roller 21.

[0033] The movable clamp 33 is positioned with its end away from the tension spring 32 facing upwards, and a friction surface 35 is provided at the contact position with the fixed clamp 34 to increase friction.

[0034] The control component 6 includes a control tube 61, an eccentric shaft 64, a lever 62, and a handle 63. The control tube 61 is rotatably connected between the first flange 22 and the second flange 23. The control tube 61 is disposed inside the roller 21 and its axial direction is aligned with that of the roller 21. The control tube 61 has several clearance through-holes 611 corresponding to several clamping components 3. The control tube 61 is fitted onto the outside of the movable clamping piece 33 of the clamping component 3 through the clearance through-holes 611 and limits the range of motion of the movable clamping piece 33. The spindle 64 is located at an eccentric position on the outer wall of the second flange 23, and one end of the eccentric spindle 64 passes through the second flange 23 and is connected to one end of the control tube 61. The lever 62 is V-shaped, and the middle part of the lever 62 is sleeved on the outside of the eccentric spindle 64 and keyed to the eccentric spindle 64. Both ends of the lever 62 are fixedly connected to handles 63 for easy hand holding. When the lever 62 drives the eccentric spindle 64 and the control tube 61 to rotate, the movable clamp 33 rotates and forms a clamping gap between it and the fixed clamp 34 to facilitate the insertion of the end of the battery pack outer casing 71.

[0035] When clamping and fixing the outer casing of the battery pack, the eccentric shaft and control tube are first rotated by the lever. The control tube will drive the movable clamping plate to rotate and open, creating a clamping gap between the movable and fixed clamping plates. At this time, the end of the battery pack casing is inserted into the clamping gap through the insertion port on the roller. After releasing the lever, the movable and fixed clamping plates will clamp the battery pack casing under the action of the tension spring. Then, the roller is rotated to achieve a quick peeling operation of the battery pack casing. Example

[0036] like Figure 10 , Figure 11 As shown, in another embodiment, power components 5 are directly provided on both axial sides of the roller 21. Two sets of symmetrical power components 5 drive the roller 21 to rotate, thereby increasing the tearing power of the wrapping assembly. Simultaneously, to control the opening and closing state of the wrapping assembly, this embodiment designs another control component, which includes a control pipe 61, a control connector 612, and a wrench 613. The control pipe 61 is rotatably connected between the first flange and the second flange. The control pipe 61 is disposed inside the roller 21 and its axial direction is aligned with that of the roller 21. The control tube 61 is provided with several clearance through holes corresponding to several clamping components. The control tube 61 is sleeved on the outside of the movable clamping piece 33 of the clamping component through the clearance through holes and the range of motion of the movable clamping piece 33 is limited and controlled. The control connector 612 is fixedly connected to the outside of the control tube 61. The roller 21 is provided with a control clearance hole 213. One end of the wrench 613 passes through the control clearance hole 213 and is inserted into the control connector 612 so that the control tube 61 can be rotated by the control connector 612, so that a clamping gap is formed between the movable clamping piece 33 and the fixed clamping piece 34.

[0037] When the clamping assembly clamps the battery casing, insert the wrench through the control clearance port into the control connector, rotate the wrench to rotate the control tube, and the control tube will cause the movable clamping plate to rotate and open, creating a clamping gap between the movable clamping plate and the fixed clamping plate. At this time, insert the battery casing end into the clamping gap through the insertion port on the roller, and then remove the wrench to perform the curling and peeling action on the battery casing.

[0038] In addition, in this embodiment, a traction assembly is provided between the frame 1 and the power assembly 5. There are two sets of traction assemblies, which are symmetrically arranged on both sides of the axial direction of the roller 21. The traction assembly includes a turnbuckle 81 and a tension spring 82. One end of the turnbuckle 81 is connected to the top of the frame 1, and the other end of the turnbuckle 81 is connected to one end of the tension spring 82. The other end of the tension spring 82 is connected to the movable frame 51 in the power assembly 5 and pulls the power assembly 5 to improve the working stability of the power assembly 5. At the same time, the movable wheel in the power assembly is replaced with a traveling roller 511. The length direction of the traveling roller 511 is consistent with the length direction of the roller 21. The traveling roller 511 is located at the front end of the roller 21, and the two axial ends of the traveling roller 51 are rotatably connected to the movable frames 51 in the two sets of power assemblies 5, respectively.

[0039] The traction assembly can pull the power assembly, allowing the traveling roller at the front end of the actuating assembly to be stably held on the upper surface of the battery pack and move along the upper surface of the battery pack, ensuring the stability of the supporting structure of the actuating assembly. At the same time, the traction assembly can adjust the traction length through turnbuckles, so that the traveling roller can contact battery packs of any thickness, making the peeling machine suitable for peeling battery packs of various specifications, thus improving the adaptability of the peeling machine.

[0040] The other components and installation and mating structures in this embodiment are the same as those in Embodiment 1, and have the same technical effects, so they will not be described again here.

[0041] In this invention, during the peeling operation, the peeling machine only needs to be moved above the battery pack. Then, a small opening is manually torn in the outer casing of the battery pack. Next, the end of the outer casing is inserted into the roller through an insertion port on one side and clamped and fixed by the clamping assembly. Finally, the roller is rotated to peel the entire outer casing off the battery pack and wrap it around the outside of the roller. This method can easily and quickly remove the entire outer casing of the battery pack without damaging the internal materials, thus improving the recycling rate of the battery pack materials. Furthermore, this battery peeling process is time-saving and labor-saving, achieving rapid peeling of the battery pack without excessive labor costs, effectively improving the peeling efficiency of the battery pack. It can fully meet the operational needs of battery recycling production lines and brings great convenience to battery recycling operations.
