Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste battery recycling and processing equipment, and in particular to a battery pack disassembly device. Background Technology
[0002] Currently, existing technology discloses a CTP battery pack dismantling device, which relates to the field of power battery pack dismantling and recycling technology. It includes a workbench and a display controller. A longitudinal guide rail assembly is mounted on the workbench, and a transverse guide rail assembly is mounted on the longitudinal guide rail assembly. A cutting module is mounted on the transverse guide rail assembly. This CTP battery pack dismantling device allows the cutting module to fully cover the battery pack and move by operating a handwheel one in the longitudinal guide rail assembly and a handwheel two in the transverse guide rail assembly. When the cutting module moves, the display controller shows the position of the laser beam illuminating the battery pack surface, captured by a camera. This helps workers determine whether the cutter is aligned with the gap between the battery cells in the battery pack. The device also operates a cylinder to drive the cutter downwards rapidly, causing it to insert into the gap between the battery cells and peel the cells at the edges from the battery pack body.
[0003] In actual operation, since the battery pack shell is mostly made of stainless steel or aluminum alloy, which has high hardness, the cutting head is prone to wear or chipping during long-term high-speed cutting. However, the existing dismantling equipment has a relatively traditional design in terms of the tool installation structure, which mostly uses nut locking or set screw fixing. When the operator needs to replace the worn cutting head, he must use auxiliary tools such as wrenches and go through a cumbersome disassembly and re-locking process. This inefficient tool replacement method causes the equipment to be down for too long on the dismantling production line, which seriously restricts the processing throughput of battery packs.
[0004] In addition, the cutting process of the metal casing will generate a large amount of conductive metal shavings and dust. If these shavings are not cleaned up in time, they will not only pollute the workshop environment, but more seriously, if the shavings fall into the cut battery pack, they can easily cause safety accidents such as short circuits or even thermal runaway. At present, most dismantling equipment lacks synchronous cleaning function and often relies on manual cleaning afterward, which poses a great safety hazard and cleaning dead corners.
[0005] Therefore, this utility model proposes a battery pack disassembly device to overcome the shortcomings of the prior art. Utility Model Content
[0006] The purpose of this invention is to provide a battery pack disassembly device that solves the problem in the prior art where the cutting head of some battery pack disassembly devices wears out quickly when disassembling high-strength outer shells, but replacing the cutting head requires a long time due to the need for tools.
[0007] This utility model provides a battery pack disassembly device, including: a drive motor, and a rotating shaft connected to the output end of the drive motor. The end of the rotating shaft is used to install a connecting plate. The bottom of the connecting plate is fixed with a cutting head for disassembling the battery pack casing, and a quick-change locking structure is disposed between the rotating shaft and the connecting plate.
[0008] The rotating shaft has a slot at its end for inserting a cross-shaped anti-slip plate, the top of the connecting plate is fixed with the cross-shaped anti-slip plate, and the outer wall of the cross-shaped anti-slip plate has a groove for accommodating the protruding part of the locking bead.
[0009] Furthermore, a radial through hole is provided on the outer peripheral wall of the rotating shaft, and a retaining bead is movably disposed in the radial through hole. A sleeve is slidably fitted on the outside of the rotating shaft, and the inner wall of the sleeve is used to press against the retaining bead in the locked position, so that the retaining bead is simultaneously engaged in the radial through hole and the retaining groove, thereby locking the connecting plate onto the rotating shaft. A return spring is provided between the sleeve and the rotating shaft, and the return spring is used to push the sleeve towards the locked position. Through the cooperation of the above structures, the disassembly head can be quickly disassembled and assembled without tools.
[0010] Preferably, the return spring surrounds the outer periphery of the rotating shaft, with one end of the return spring abutting against the inner side of the housing and the other end abutting against the annular flange on the rotating shaft near the drive motor.
[0011] Preferably, it also includes a base, a gantry frame, and a connecting wall. The gantry frame is slidably connected to the top of the base via sliding feet at its bottom. The connecting wall is slidably connected to the gantry frame horizontally. The drive motor is slidably connected to the connecting wall vertically, thereby forming a three-axis linkage structure that can cover all corners of the battery pack.
[0012] Preferably, a cleaning assembly is fixed to the inner side of the sliding foot. The cleaning assembly includes a connecting rod and a sweeping head fixed to the bottom end of the connecting rod. The sweeping head follows the movement of the gantry frame to clean the surface of the base.
[0013] Preferably, a collection groove for collecting waste swept in by the sweeping head is detachably installed on the side wall of the base, and the collection groove is locked to the base by a pin.
[0014] Preferably, the pin is connected to a toggle pin for manual operation, and the pin can be moved by toggling the toggle pin.
[0015] Preferably, a push spring is provided between the pin and the base, the push spring being used to provide a reset force after the pin is unlocked.
[0016] The beneficial effects are: 1. This utility model solves the problems of existing technologies requiring tools, cumbersome operation, and long time consumption when replacing the battery pack disassembly cutter head by setting a quick-release locking mechanism composed of a housing, a return spring, a retaining ball, and a cross anti-slip plate. It achieves the technical effect of quick disassembly and assembly of the cutter head without tools, significantly shortens equipment maintenance downtime, and improves the disassembly and processing efficiency of waste battery packs.
[0017] 2. This utility model solves the problem that conductive metal debris generated during disassembly is prone to accumulate and may cause battery short circuits if manual cleaning is not timely by setting up a cleaning component linked to the gantry and an automatic cleaning and collection mechanism that works in conjunction with it. It achieves the technical effect of automatically completing debris cleaning and collection while cutting operations, effectively reducing the safety risks during battery pack disassembly while keeping the work area clean.
[0018] 3. This utility model uses a cross-shaped anti-slip plate and a slot at the end of the rotating shaft to transmit torque, which solves the problem of slippage at the connection point due to excessive load when cutting the shell of a high-hardness battery pack. It achieves the technical effect of transmitting large torque and reliable connection, ensuring the stability of power transmission during the forceful disassembly process.
[0019] 4. This utility model solves the problem of inconvenient disassembly and dumping of traditional waste collection containers by setting a simple locking device consisting of a toggle pin, a latch pin and a push spring to fix the collection trough. It achieves the technical effect of quick disassembly and installation of the collection trough by hand, and simplifies the cleaning process of metal waste. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Example: Reference Figures 1 to 4 This utility model provides a battery pack disassembly device, which aims to solve the problems of cumbersome operation, long time consumption and reduced production efficiency of cutting tool head replacement in the prior art.
[0025] like Figure 1 As shown, it includes a base 1 and a gantry 5 slidably connected to the top of the base 1. The base 1 serves as the mounting base for the entire device and supports all working parts. The gantry 5 slides back and forth along its length on a linear guide rail opened at the top of the base 1 via sliding feet 2 at the bottom.
[0026] A connecting wall 6 is horizontally slidably connected to the gantry frame 5, and a cutting mechanism 4 is vertically slidably connected to the connecting wall 6. Through the three-axis linkage of the gantry frame 5, the connecting wall 6 and the cutting mechanism 4, the cutting mechanism 4 can reach any position in the working area above the base 1.
[0027] Reference Figure 4 The cutting mechanism 4 includes a drive motor 41, the output end of which is fixedly connected to a rotating shaft 42. The rotating shaft 42 is used to transmit rotational power. The end of the rotating shaft 42 is used to install a connecting plate 47. A cutter head 48 is fixed at the bottom of the connecting plate 47. A slot for inserting a cross anti-slip plate 45 is provided at the end of the rotating shaft 42. A cross anti-slip plate 45 matching the slot is fixed at the top of the connecting plate 47. The cooperation between the cross anti-slip plate 45 and the slot is used to efficiently transmit torque to the connecting plate 47 when the drive motor 41 drives the rotating shaft 42 to rotate, preventing slippage under high load. A radial through hole is provided on the outer peripheral wall of the rotating shaft 42. A retaining bead 46 is movably disposed in the radial through hole. A corresponding groove for accommodating the protruding part of the retaining bead 46 is provided on the outer wall of the cross anti-slip plate 45.
[0028] The outer side of the rotating shaft 42 is fitted with a housing 44. When the inner wall of the housing 44 is in the locked position, it presses the retaining bead 46 inward, so that part of the retaining bead 46 is forcibly inserted into the groove of the cross anti-slip plate 45, thereby firmly locking the connecting plate 47 onto the rotating shaft 42 by the cross anti-slip plate 45. The rotating shaft 42 is also provided with a return spring 43. The return spring 43 surrounds the outer circumference of the rotating shaft 42. One end of the return spring 43 abuts against the housing 44, and the other end abuts against the annular flange on the rotating shaft 42 near the drive motor 41. It is used to be compressed when the housing 44 slides axially and to provide elastic force to reset it. It also includes a sweeping assembly 35 and an automatic cleaning and collection mechanism 3 that cooperates with it. The sweeping assembly 35 is linked with the gantry 5, and the automatic cleaning and collection mechanism 3 is used to collect the debris collected during sweeping.
[0029] Reference Figure 1 , Figure 2 and Figure 3 The cleaning assembly 35 includes a connecting rod 351 and a sweeping head 352 fixed to the bottom of the connecting rod 351. The connecting rod 351 is fixed to the inner side of the sliding foot 2 at the bottom of the gantry frame 5. The sweeping head 352 is preferably a wear-resistant flexible brush. When the sliding foot 2 drives the gantry frame 5 to slide on the base 1, the sweeping head 352 will simultaneously clean the workbench surface of the base 1.
[0030] An automatic cleaning and collection mechanism 3 is detachably installed on the side wall of the base 1. The automatic cleaning and collection mechanism 3 includes a collection trough 31 for collecting debris. The opening of the collection trough 31 faces the working area, so that the debris collected by the sweeping head 352 can smoothly enter the collection trough 31.
[0031] Reference Figure 3 The device includes a pin 33, which passes through the side wall of the base 1 and engages in the positioning hole at the edge of the collection groove 31, thereby firmly locking the collection groove 31 onto the base 1. The pin 33 is connected to a toggle pin 34 for manual operation. When the user needs to clean the collection groove 31, he can move the pin 33 upward by pushing the toggle pin 34 upward, so that it completely disengages from the positioning hole of the collection groove 31. In order to enable the pin 33 to automatically reset after unlocking or to provide feedback force during unlocking, the automatic cleaning collection mechanism 3 also includes a push spring 32. The push spring 32 is disposed between the pin 33 and the structural wall of the base 1. When the toggle pin 34 is pushed upward to move the pin 33, the pin 33 will simultaneously squeeze the push spring 32.
[0032] The working principle of this utility model is as follows: Regarding the quick replacement process of the cutter head 48: When it is necessary to replace the worn cutter head 48, the operator first slides the housing 44 upward by hand. The movement of the housing 44 will compress the return spring 43 between it and the rotating shaft 42. When the housing 44 slides upward to a certain position, its inner wall completely disengages from the radial pressure on the retaining ball 46. The retaining ball 46 then loses its external restraint and can move freely inward within the radial through hole, no longer forcibly stuck in the groove of the cross anti-slip plate 45. At this moment, the lock between the connecting plate 47 and the rotating shaft 42 is released, and the operator can easily pull the connecting plate 47 with the old cutter head 48, together with the cross anti-slip plate 45 on its top, downward from the end of the rotating shaft 42.
[0033] During installation, the operator inserts the new connecting disc 47, which is equipped with the new cutter head 48, with the cross anti-slip plate 45 on its top aligned with the slot at the end of the rotating shaft 42. Once inserted, the operator releases the previously raised sleeve 44. Under the elastic force stored in the return spring 43, the sleeve 44 will instantly spring back downwards, and its inner wall will press the retaining bead 46 again, forcing the retaining bead 46 to simultaneously engage with the radial through hole of the rotating shaft 42 and the slot of the cross anti-slip plate 45, thereby completing the quick and reliable locking of the new connecting disc 47.
[0034] Regarding the automatic cleaning and collection process: During equipment operation, drive motor 41 drives cutter head 48 to perform cutting operations. Gantry frame 5 slides on base 1 via sliding foot 2. The cleaning component 35, fixed inside sliding foot 2, moves accordingly. The sweeping head 352 at its bottom continuously cleans the worktable, collecting and sweeping the iron filings and other debris generated during processing towards the collection trough 31. Finally, the debris is swept into the collection trough 31. When the collection trough 31 is full of debris, the operator moves the actuating pin 34 upward. The actuating pin 34 drives the pin 33 to slide upward and squeezes the push spring 32. When the pin 33 is completely pulled out of the positioning hole at the edge of the collection trough 31, the collection trough 31 can be easily pulled out to empty the debris. After cleaning, the collection trough 31 is pushed back to its original position, the actuating pin 34 is released, the push spring 32 rebounds, pushes the pin 33 to reset, and relocks the collection trough 31.
