Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pack breaking equipment, in particular to a dismounting mechanism and a dismounting method for a blade of a battery pack breaking equipment. BACKGROUND

[0002] With the vigorous development of the new energy automobile industry, the demand for power battery cascade utilization and recycling is showing explosive growth. In the physical recycling process of the battery, the powerful breaking equipment occupies a core position, and the blade assembly directly bears a huge impact and wear, and the blade assembly directly contacts the electrolyte of the battery, which is easy to be corroded and damaged, and needs to be frequently replaced to maintain the breaking and disassembly efficiency of the battery pack.

[0003] In the prior art, the dismounting of the blade highly depends on manual operation, and the worker removes the fasteners such as bolts by means of pneumatic or hydraulic tools. Since the current mainstream breaking equipment adopts a flow line breaking process, the worker needs to carry the tools to move on the production line, which wastes a lot of time, and in the narrow position of the flow line, the worker's movement with the tools is not convenient, which is more likely to cause the dismounting efficiency of the blade to decrease, and further cause the production efficiency of the battery pack breaking process to decrease. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a dismounting mechanism and a dismounting method for a blade of a battery pack breaking equipment.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A dismounting mechanism, comprising a dismounting sliding rail and a dismounting module, the dismounting sliding rail has a starting point stop position and an end point stop position at both ends respectively, the dismounting module can move bidirectionally between the starting point stop position and the end point stop position along the dismounting sliding rail; the track path of the dismounting sliding rail passes through the mounting positions of the blades in sequence, and a sliding blocking module is arranged at each mounting position; in the process of bidirectional movement of the dismounting module between the starting point stop position and the end point stop position, the dismounting module can pass through each mounting position in sequence; when the dismounting module moves from the starting point stop position to the end point stop position, and the blade installed at any mounting position needs to be dismounted, the sliding blocking module corresponding to the mounting position can block the continuous movement of the dismounting module, and drive the reverse blocking module to block the reverse movement of the dismounting module; when the dismounting module stops at the mounting position, the blade installed at the mounting position needs to be dismounted, after the dismounting of the blade installed at the mounting position is completed, the sliding blocking module and the reverse blocking module no longer block the movement of the dismounting module, and the dismounting module can continue to move to the end point stop position.

[0007] Preferably, the disassembly module includes a sliding drive base, a side extension bracket, and a disassembly unit; the disassembly unit is disposed at the top of the side extension bracket, the bottom end of the side extension bracket is fixed to the sliding drive base, and the side extension bracket can support the disassembly unit to extend to the side of the disassembly sliding track near each installation position; the bottom end of the sliding drive base is engaged with the disassembly sliding track, and a sliding drive unit is disposed inside the sliding drive base, which can drive the sliding drive base to move along the direction limited by the disassembly sliding track.

[0008] Preferably, the sliding drive base is provided with a sliding clamping block located outside the disassembly sliding track, and the sliding clamping block is slidably connected to the disassembly sliding track; the sliding drive unit includes a servo motor, a reduction gearbox, and a drive roller, and the input end and output end of the reduction gearbox are respectively poweredly connected to the servo motor and the drive roller; the drive roller is rotatably connected to the side of the sliding drive base located inside the disassembly sliding track, and the drive roller is in contact with the disassembly sliding track.

[0009] Preferably, the side extension bracket includes a lifting bracket and a displacement adjustment guide rail. The displacement adjustment guide rail is installed at the top of the lifting bracket, and the disassembly unit can move laterally under the drive of the displacement adjustment guide rail. The disassembly unit includes a lifting drive guide rail, a disassembly mounting bracket, a disassembly drive motor, and a disassembly clamp. The lifting drive guide rail can drive the disassembly mounting bracket to move longitudinally. The disassembly clamp is rotatably connected to the bottom end of the disassembly mounting bracket. The output shaft of the disassembly drive motor can pass through the disassembly mounting bracket and be coaxially fixed between the disassembly clamps.

[0010] Preferably, the sliding blocking module includes a blocking mounting base, a movable blocking block, and a blocking cylinder. The fixed end and the movable end of the blocking cylinder are fixed to the blocking mounting base and the movable blocking block, respectively. When the blade installed at the mounting position corresponding to the sliding blocking module needs to be disassembled, the blocking cylinder can drive the movable blocking block to move onto the moving path of the sliding driving base, preventing the sliding driving base from continuing to move along the disassembly sliding track.

[0011] Preferably, an extended stop block is provided on one side of the sliding drive base, and a buffer groove is provided on the side of the movable blocking block facing the starting position of the disassembly sliding track. A buffer stop block is slidably disposed inside the buffer groove. The buffer stop block and the inner wall of the buffer groove are elastically connected by a buffer spring. When the movable blocking block prevents the sliding drive base from continuing to move, the extended stop block can abut against the buffer stop block and drive the buffer stop block to move into the buffer groove against the elastic force of the buffer spring.

[0012] Preferably, the reverse blocking module includes a follower crossbar and a follower stop block. The two ends of the follower crossbar are fixed to the movable stop block and the follower stop block, respectively. The follower stop block can rise and fall synchronously with the movable stop block. The distance between the movable stop block and the movable stop block is greater than the length of the extended stop block. A reverse drive plate is slidably provided on one side of the follower crossbar. A conduction groove is provided on one side of the inner wall of the buffer groove. An input gear is rotatably provided inside the conduction groove. The two sides of the input gear mesh with the buffer stop block and the reverse drive plate, respectively.

[0013] Preferably, the follower block has a reverse abutment groove on the side facing the end position of the disassembly sliding track, a reverse abutment block is slidably disposed inside the reverse abutment groove, and an abutment drive groove is disposed on one side of the inner wall of the reverse abutment groove; an output gear is rotatably disposed inside the abutment drive groove, and the two ends of the output gear are respectively engaged with the gears between the reverse abutment block and the reverse drive plate.

[0014] Preferably, the transmission ratio between the output gear and the reverse abutment block and the reverse drive plate is greater than the transmission ratio between the input gear and the buffer stop and the reverse drive plate; during the process of the buffer stop being abutted and moved by the sliding drive base, the distance the buffer stop moves is less than the distance the reverse abutment block moves.

[0015] A method for disassembling the blades of a battery pack crushing device, using the aforementioned disassembly mechanism, includes the following steps:

[0016] The disassembly sliding rail is assembled with the battery pack crushing equipment, and the track path of the disassembly sliding rail passes through the installation positions of each blade in sequence.

[0017] Based on the usage time and service life of each blade, determine whether the blade needs to be disassembled and replaced, so as to drive the corresponding sliding blocking module to switch to the blocking state;

[0018] During the process of the disassembly module moving from the starting position to the ending position, the sliding blocking module corresponding to the installation position of the blade that needs to be disassembled blocks the continued movement of the disassembly module in a blocking state, and the disassembly module needs to disassemble the blade installed at that installation position.

[0019] The disassembly of several blades in the battery pack crushing equipment is completed sequentially.

[0020] Compared with the prior art, the present invention provides a disassembly mechanism and a method for disassembling blades in a battery pack crushing device, which has the following advantages:

[0021] 1. This disassembly mechanism uses a sliding track that sequentially passes through the installation positions of each blade. The sliding track has a starting stop and an ending stop at each end, allowing the disassembly module to move bidirectionally between these positions. In practical use, when a blade at a specific installation position needs to be disassembled, as the disassembly module moves from the starting stop to the ending stop, and at any installation position where a blade needs disassembly, the corresponding sliding blocking module prevents further movement of the disassembly module and drives a reverse blocking module to prevent reverse movement. When the disassembly module stops at an installation position, it can disassemble the blade at that position. After disassembly, the sliding blocking module and the reverse blocking module no longer obstruct the movement of the disassembly module, allowing it to continue moving towards the ending stop. This sequentially disassembles blades at each installation position, improving blade replacement efficiency and ensuring efficient protection against battery pack breakage.

[0022] 2. In this disassembly mechanism, the servo motor drives the drive roller to rotate through the gearbox. The friction between the drive roller and the disassembly sliding track allows the sliding drive base to slide along the disassembly sliding track, creating a limiting effect. This causes the sliding drive base to move the side extension bracket and the disassembly unit along the disassembly sliding track. The disassembly unit is driven to move laterally by the displacement adjustment guide rail at the top of the lifting bracket. This, combined with the lifting drive guide rail, drives the disassembly mounting support to move longitudinally. The disassembly drive motor drives the disassembly chuck to rotate, thereby disassembling the fasteners and ultimately the blade.

[0023] 3. In this disassembly mechanism, the sliding drive base can continue to move, allowing the extended abutment block to abut against the buffer stop block and drive the buffer stop block to overcome the elastic force of the buffer spring and move into the buffer groove. Since the input gear is rotatably arranged inside the transmission groove, and the two sides of the input gear mesh with the gears between the buffer stop block and the reverse drive plate respectively, the buffer stop block and the reverse drive plate move in opposite directions. Furthermore, since the output gear is rotatably arranged inside the abutment drive groove, and the two ends of the output gear mesh with the gears between the reverse abutment block and the reverse drive plate respectively, the reverse abutment block and the reverse drive plate move in opposite directions, thus making the reverse abutment block and the buffer stop block move in the same direction.

[0024] 4. In this disassembly mechanism, the transmission ratio between the output gear and the reverse abutment block and the reverse drive plate is greater than the transmission ratio between the input gear and the buffer stop and the reverse drive plate. During the movement of the buffer stop by the sliding drive base, the distance the buffer stop moves is less than the distance the reverse abutment block moves, causing the gap between the reverse abutment block and the buffer stop to gradually decrease. Thus, when the buffer stop moves to the maximum limit position, the sliding drive base can be aligned with the installation position, thereby effectively positioning the sliding drive base and ensuring that the disassembly unit set on the sliding drive base can effectively perform the disassembly operation, effectively reducing the calibration time required for disassembly and improving the disassembly efficiency of the blade.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a disassembly mechanism and a method for disassembling blades of a battery pack crushing device.

[0041] Example 1:

[0042] Please see Figures 1-11 A disassembly mechanism includes a disassembly sliding track 1 and a disassembly module 2. The disassembly sliding track 1 has a starting stop and an ending stop at its two ends. The disassembly module 2 can move bidirectionally between the starting stop and the ending stop along the disassembly sliding track 1. The track path of the disassembly sliding track 1 passes through the installation positions of each blade in sequence, and a sliding blocking module 3 is provided at each installation position. During the bidirectional movement of the disassembly module 2 between the starting stop and the ending stop, the disassembly module 2 can pass through each installation position in sequence. When the disassembly module 2 moves from the starting stop to the ending stop, and a blade installed at any installation position needs to be disassembled, the sliding blocking module 3 corresponding to that installation position can block the continued movement of the disassembly module 2 and drive a reverse blocking module 4 to block the reverse movement of the disassembly module 2. When the disassembly module 2 stops at an installation position, the blade installed at that installation position needs to be disassembled. After the blade installed at that installation position is disassembled, the sliding blocking module 3 and the reverse blocking module 4 no longer block the movement of the disassembly module 2, and the disassembly module 2 can continue to move towards the ending stop.

[0043] In practical use, firstly, a disassembly sliding rail 1 is set up, and the track path of the disassembly sliding rail 1 passes sequentially through the installation positions of each blade (or other components that need to be disassembled). The disassembly sliding rail 1 has a starting stop and an ending stop at each end, allowing the disassembly module 2 to move bidirectionally between the starting stop and the ending stop. During actual use, when a blade (or other component) at an installation position needs to be disassembled (blades used in battery pack crushing equipment are damaged quickly due to the electrolyte in the battery pack), the disassembly module 2 moves from the starting stop to the ending stop. In this process, when a blade installed at any position needs to be disassembled, the sliding blocking module 3 corresponding to that position can block the disassembly module 2 from continuing to move and drive the reverse blocking module 4 to block the disassembly module 2 from moving in the opposite direction. When the disassembly module 2 is stationary at the installation position, the blade installed at that position needs to be disassembled. After the blade installed at that position is disassembled, the sliding blocking module 3 and the reverse blocking module 4 no longer block the movement of the disassembly module 2, and the disassembly module 2 can continue to move towards the endpoint position. This allows the disassembly process of each blade installation position that needs to be disassembled to be performed sequentially, thereby improving the efficiency of blade replacement and ensuring the efficiency of battery pack breakage.

[0044] Example 2:

[0045] Please see Figures 1-11The difference from the above embodiment is that the disassembly module 2 includes a sliding drive base 21, a side extension bracket 22, and a disassembly unit 23; the disassembly unit 23 is disposed at the top of the side extension bracket 22, the bottom end of the side extension bracket 22 is fixed to the sliding drive base 21, and the side extension bracket 22 can support the disassembly unit 23 to extend to the side of the disassembly sliding track 1 near each installation position; the bottom end of the sliding drive base 21 is fitted with the disassembly sliding track 1, and a sliding drive unit 24 is disposed inside the sliding drive base 21, which can drive the sliding drive base 21 to move along the direction limited by the disassembly sliding track 1.

[0046] A sliding drive base 21 is provided with a sliding clamping block 211 located outside the disassembly sliding rail 1. The sliding clamping block 211 is slidably connected to the disassembly sliding rail 1. The sliding drive unit 24 includes a servo motor 241, a reduction gearbox 242 and a drive roller 243. The input end and output end of the reduction gearbox 242 are respectively poweredly connected to the servo motor 241 and the drive roller 243. The drive roller 243 is rotatably connected to one side of the sliding drive base 21 located inside the disassembly sliding rail 1, and the drive roller 243 is in contact with the disassembly sliding rail 1.

[0047] The side extension bracket 22 includes a lifting bracket 221 and a displacement adjustment guide rail 222. The displacement adjustment guide rail 222 is installed at the top of the lifting bracket 221. The disassembly unit 23 can move laterally under the drive of the displacement adjustment guide rail 222. The disassembly unit 23 includes a lifting drive guide rail 231, a disassembly and installation support 232, a disassembly drive motor 233, and a disassembly chuck 234. The lifting drive guide rail 231 can drive the disassembly and installation support 232 to move longitudinally. The disassembly chuck 234 is rotatably connected to the bottom end of the disassembly and installation support 232. The output shaft of the disassembly drive motor 233 can pass through the disassembly and installation support 232 and be coaxially fixed between the disassembly chuck 234 and the disassembly chuck 234.

[0048] In practical use, the starting and ending positions of the disassembly sliding rail 1 are equipped with buffer structures to ensure that the disassembly module 2 stops at the starting and ending positions. In actual use, the starting and ending positions of multiple disassembly sliding rails 1 can be connected end to end by setting multiple disassembly sliding rails 1 in sequence, so that the disassembly module 2 can move continuously in a loop and disassemble each position in the entire movement path.

[0049] Specifically, the servo motor 241 drives the drive roller 243 to rotate via the reduction gearbox 242. The friction between the drive roller 243 and the disassembly sliding track 1 allows the sliding drive base 21 to move along the disassembly sliding track 1, thus limiting its movement due to the sliding connection between the sliding clamping block 211 and the disassembly sliding track 1. In practical use, the sliding drive base can be equipped with storage boxes for damaged blades, disassembled screws and other fasteners, and replacement blades. The movement can be achieved by lifting the top of the support 221. The displacement adjustment guide rail 222 drives the disassembly unit 23 to move laterally, and works with the lifting drive guide rail 231 to drive the disassembly and installation support 232 to move longitudinally. This drives the disassembly chuck 234 to move between the fastener storage box and the fastener connection position at the installation location. The disassembly drive motor 233 drives the disassembly chuck 234 to rotate, thereby disassembling, gripping, placing, and installing the fasteners. In actual use, a structure such as a robotic arm can be set up to grip the blades, thereby disassembling and installing the blades. This allows for the disassembly and replacement of blades at various installation positions where blades need to be disassembled and replaced.

[0050] Example 3:

[0051] Please see Figures 1-11 The difference from the above embodiment is that the sliding blocking module 3 includes a blocking mounting base 31, a movable blocking block 32, and a blocking cylinder 33. The fixed end and the movable end of the blocking cylinder 33 are fixed to the blocking mounting base 31 and the movable blocking block 32, respectively. When the blade installed at the mounting position corresponding to the sliding blocking module 3 needs to be disassembled, the blocking cylinder 33 can drive the movable blocking block 32 to move onto the moving path of the sliding drive base 21, preventing the sliding drive base 21 from continuing to move along the disassembly sliding track 1.

[0052] An extension abutment 212 is provided on one side of the sliding drive base 21. A buffer groove 321 is provided on the side of the movable blocking block 32 facing the starting position of the disassembly sliding track 1. A buffer stop 34 is slidably arranged inside the buffer groove 321. The buffer stop 34 and the inner wall of the buffer groove 321 are elastically connected by a buffer spring 341. When the movable blocking block 32 blocks the sliding drive base 21 from continuing to move, the extension abutment 212 can abut against the buffer stop 34 and drive the buffer stop 34 to overcome the elastic force of the buffer spring 341 and move into the buffer groove 321.

[0053] The reverse blocking module 4 includes a follower crossbar 41 and a follower stop 42. The two ends of the follower crossbar 41 are fixed to the movable stop block 32 and the follower stop block 42, respectively. The follower stop block 42 can rise and fall synchronously with the rise and fall of the movable stop block 32. The distance between the movable stop blocks 32 is greater than the length of the extension block 212. A reverse drive plate 43 is slidably arranged on one side of the follower crossbar 41. A conduction channel 322 is arranged on one side of the inner wall of the buffer groove 321. An input gear 323 is rotatably arranged inside the conduction channel 322. The two sides of the input gear 323 are engaged with the buffer stop block 34 and the reverse drive plate 43, respectively.

[0054] The follower block 42 has a reverse abutment groove 421 on the side facing the end position of the disassembly sliding track 1. A reverse abutment block 44 is slidably arranged inside the reverse abutment groove 421. An abutment drive groove 422 is provided on one side of the inner wall of the reverse abutment groove 421. An output gear 423 is rotatably arranged inside the abutment drive groove 422. The two ends of the output gear 423 are respectively engaged with the reverse abutment block 44 and the reverse drive plate 43.

[0055] The transmission ratio between the output gear 423 and the reverse abutment block 44 and the reverse drive plate 43 is greater than the transmission ratio between the input gear 323 and the buffer stop block 34 and the reverse drive plate 43; during the process of the buffer stop block 34 being abutted and moved by the sliding drive base 21, the distance that the buffer stop block 34 moves is less than the distance that the reverse abutment block 44 moves.

[0056] In practical use, when the sliding drive base 21 moves between a set of sliding blocking modules 3 and reverse blocking modules 4, the blade can be disassembled depending on the installation position between the set of sliding blocking modules 3 and reverse blocking modules 4. When the blade does not need to be disassembled, the set of sliding blocking modules 3 and reverse blocking modules 4 will not perform any operation.

[0057] When the blade needs to be disassembled, the blocking cylinder 33 drives the movable blocking block 32, the follower crossbar 41, and the follower stop 42 to rise synchronously, so that the movable blocking block 32 and the follower stop 42 can rise and be on the moving path of the extension abutment block 212. Specifically, the movable blocking block 32 and the follower stop 42 are located on both sides of the extension abutment block 212. At this time, since the sliding drive base 21 can continue to move, the extension abutment block 212 can abut against the buffer stop 34 and drive the buffer stop 34 to overcome the elastic force of the buffer spring 341 and move into the buffer groove 321. Since the input gear 323 is rotatably arranged inside the transmission groove 322, and the two sides of the input gear 323 mesh with the gears between the buffer stop 34 and the reverse drive plate 43 respectively, the buffer stop 34 and the reverse drive plate 43 move in opposite directions. Furthermore, since the output gear 423 is rotatably arranged inside the abutment drive groove 422, and the two ends of the output gear 423 are respectively connected to the reverse abutment block 44 and the reverse drive plate 43. The gears mesh, causing the reverse abutment block 44 and the reverse drive plate 43 to move in opposite directions. This results in the reverse abutment block 44 and the buffer stop block 34 moving in the same direction. Since the transmission ratio between the output gear 423 and the reverse abutment block 44 and the reverse drive plate 43 is greater than the transmission ratio between the input gear 323 and the buffer stop block 34 and the reverse drive plate 43, the buffer stop block 34 moves a shorter distance than the reverse abutment block 44 during the abutment movement of the buffer stop block 34 by the sliding drive base 21. This causes the gap between the reverse abutment block 44 and the buffer stop block 34 to gradually decrease. When the buffer stop block 34 moves to its maximum limit position (completely retracted into the buffer groove 321), the sliding drive base 21 can be aligned with the installation position, effectively positioning the sliding drive base 21 and ensuring that the disassembly unit 23 on the sliding drive base 21 can effectively perform the disassembly operation. This effectively reduces the calibration time required for disassembly and improves the disassembly efficiency of the blade.

[0058] Example 4:

[0059] Please see Figures 12-13 A method for disassembling the blades of a battery pack crushing device, using a disassembly mechanism as described in any one of Embodiments 1-3 to disassemble the blades of the battery pack crushing device, includes the following steps:

[0060] The disassembly sliding rail 1 is assembled with the battery pack crushing equipment, and the track path of the disassembly sliding rail 1 passes through the installation positions of each blade in sequence.

[0061] Based on the usage time and service life of each blade, determine whether the blade needs to be disassembled and replaced, so as to drive the corresponding sliding blocking module 3 to switch to the blocking state;

[0062] During the process of disassembly module 2 moving from the starting position to the ending position, the sliding blocking module 3 corresponding to the installation position of the blade that needs to be disassembled blocks the continued movement of disassembly module 2 in a blocking state, and disassembly module 2 needs to disassemble the blade installed at that installation position.

[0063] The disassembly of several blades in the battery pack crushing equipment is completed sequentially.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

When the blade installed at the corresponding installation position of the sliding blocking module needs to be disassembled, the blocking cylinder can drive the movable blocking block to move onto the moving path of the sliding drive base, preventing the sliding drive base from continuing to move along the disassembly sliding track.

6. A disassembly mechanism according to claim 5, characterized in that: An extended stop block is provided on one side of the sliding drive base, and a buffer groove is provided on the side of the movable blocking block facing the starting position of the disassembly sliding track. A buffer stop block is slidably arranged inside the buffer groove. The buffer stop and the inner wall of the buffer groove are elastically connected by a buffer spring. When the movable stop block prevents the sliding drive base from moving further, the extended abutment can abut against the buffer stop block and drive the buffer stop block to overcome the elastic force of the buffer spring and move into the buffer groove.

7. A disassembly mechanism according to claim 6, characterized in that: The reverse blocking module includes a follower crossbar and a follower block. The two ends of the follower crossbar are fixed to the movable blocking block and the follower block, respectively. The follower block can rise and fall synchronously with the movable blocking block. The distance between the movable blocking blocks is greater than the length of the extended block. A reverse drive plate is slidably provided on one side of the follower crossbar, and a conduction channel is provided on one side of the inner wall of the buffer groove. An input gear is rotatably provided inside the conduction channel, and the two sides of the input gear mesh with the buffer block and the reverse drive plate respectively.

8. A disassembly mechanism according to claim 7, characterized in that: The follower block has a reverse abutment groove on one side facing the end position of the disassembly sliding track, a reverse abutment block is slidably arranged inside the reverse abutment groove, and an abutment drive groove is provided on one side of the inner wall of the reverse abutment groove. An output gear is rotatably mounted inside the abutment drive groove, and the two ends of the output gear mesh with the gears between the reverse abutment block and the reverse drive plate, respectively.

9. A disassembly mechanism according to claim 8, characterized in that: The transmission ratio between the output gear and the reverse abutment block and the reverse drive plate is greater than the transmission ratio between the input gear and the buffer block and the reverse drive plate; During the movement of the buffer block by the sliding drive base, the distance the buffer block moves is less than the distance the reverse abutting block moves.

10. A method for disassembling blades in a battery pack crushing device, characterized in that, The disassembly of the blades of the battery pack crushing equipment using a disassembly mechanism as described in any one of claims 1-9 includes the following steps: The disassembly sliding rail is assembled with the battery pack crushing equipment, and the track path of the disassembly sliding rail passes through the installation positions of each blade in sequence. Based on the usage time and service life of each blade, determine whether the blade needs to be disassembled and replaced, so as to drive the corresponding sliding blocking module to switch to the blocking state; During the process of the disassembly module moving from the starting position to the ending position, the sliding blocking module corresponding to the installation position of the blade that needs to be disassembled blocks the continued movement of the disassembly module in a blocking state, and the disassembly module needs to disassemble the blade installed at that installation position. The disassembly of several blades in the battery pack crushing equipment is completed sequentially.
