[0104] Some embodiments of the present application will be described in detail below with reference to the drawings.

[0105] Please refer to Figure 1 , the embodiment of the present application provides a disassembly and assembly mechanism 100. The disassembly and assembly mechanism 100 is used for disassembling and assembling the tool handle 2 (please refer to Figure 5 ), and can also be understood as disassembling and assembling the tool 3 from the tool handle 2 (please refer to Figure 5 ). The tool handle 2 includes a tool handle body 2c (please refer to Figure 5 ) and a tool handle nut 2a rotatably arranged on the tool handle body 2c (please refer to Figure 5 ). A plurality of disassembly and assembly grooves 2b are arranged on the outer peripheral side of the tool handle nut 2a (please refer to Figure 5 ). The tool handle body 2c is used for mounting the tool 3. By rotating the tool handle nut 2a, the tool 3 on the tool handle body 2c can be locked or loosened. Specifically, the disassembly and assembly mechanism 100 can loosen the tool handle nut 2a on the tool handle 2 from the tool handle body 2c to disassemble and assemble the tool 3. The disassembly and assembly mechanism 100 drives the tool handle nut 2a to rotate forward and backward by inserting into the disassembly and assembly groove 2b, so as to loosen and lock the tool handle nut 2a from the tool handle body 2c, and further loosen and lock the tool 3.

[0106] Please refer to in combination Figure 2 and Figure 3, the disassembly and assembly mechanism 100 includes a driving member 10, a coupling assembly 20, and a disassembly and assembly component 30. The coupling assembly 20 is connected to the driving member 10 to rotate under the drive of the driving member 10. A receiving hole 21 is formed at one end of the coupling assembly 20 facing away from the driving member 10. The disassembly and assembly component 30 includes a disassembly and assembly member 31, a plurality of plugging members 32, and a plurality of elastic members 33. The disassembly and assembly member 31 is connected to the end of the coupling assembly 20 facing away from the driving member 10. A central hole 311 communicating with the receiving hole 21 is formed in the disassembly and assembly member 31. A plurality of receiving grooves 312 are formed on one side of the disassembly and assembly member 31 facing the coupling assembly 20. The plurality of receiving grooves 312 are arranged around the central hole 311 and are all communicated with the central hole 311. The plurality of receiving grooves 312, the plurality of plugging members 32, and the plurality of elastic members 33 are respectively arranged in one-to-one correspondence. Each plugging member 32 is slidably arranged in a corresponding receiving groove 312. Each elastic member 33 is arranged in a corresponding receiving groove 312 and abuts between the disassembly and assembly member 31 and the corresponding plugging member 32. A plugging portion 321 protrudes from one end of the plugging member 32 facing away from the elastic member 33. Among them, the plugging portion 321 is adapted to the disassembly and assembly groove 2b on the tool handle nut 2a of the tool handle 2. Exemplarily, the plugging portion 321 is generally trapezoidal, and the elastic member 33 can be a spring. When the tool handle 2 is inserted into the central hole 311 and the receiving hole 21, the plurality of plugging portions 321 are inserted into the disassembly and assembly groove 2b of the tool handle nut 2a under the elastic force of the plurality of elastic members 33. The driving member 10 is used to drive the coupling assembly 20 and the disassembly and assembly member 31 to rotate. The disassembly and assembly member 31 drives the plurality of plugging members 32 to rotate. The plurality of plugging members 32 drive the tool handle nut 2a to rotate by inserting into the tool handle nut 2a through the corresponding plugging portions 321, so as to disassemble and assemble the tool handle 2.

[0107] When disassembling and assembling the tool handle 2, the driving member 10 of the disassembly and assembly mechanism 100 can be connected to an external robotic arm or other power mechanism to enable the disassembly and assembly mechanism 100 to move mechanized. The driving member 10 can be a servo motor. The external robotic arm drives the entire disassembly and assembly mechanism 100 to move closer to the tool handle 2. A tool 3 is mounted on the tool handle body 2c of the tool handle 2. If the tool 3 is in a locked state on the tool handle body 2c at this time, the disassembly and assembly mechanism 100 is used to loosen the tool handle nut 2a to facilitate the replacement of a new tool 3. If the tool 3 is in a loose state on the tool handle body 2c at this time, the disassembly and assembly mechanism 100 is used to lock the tool handle nut 2a. When the disassembly and assembly mechanism 100 approaches the assembled tool handle 2, the disassembly and assembly member 31 and the coupling assembly 20 of the disassembly and assembly mechanism 100 are inserted into the tool handle 2 and the tool 3 through the central hole 311 and the accommodating hole 21, and multiple plugging members 32 are substantially in the same plane as the disassembly slot 2b on the tool handle nut 2a of the tool handle 2. If the plugging member 32 is facing the disassembly slot 2b at this time, the plugging portion 321 of the plugging member 32 is adaptively inserted into the disassembly slot 2b under the elastic force of the corresponding elastic member 33. If the plugging member 32 is not facing the disassembly slot 2b at this time, the driving member 10 drives the coupling assembly 20 to rotate slowly, and the coupling assembly 20 drives the disassembly and assembly member 31 to rotate slowly, so that the plugging member 32 faces the disassembly slot 2b. After the plugging portion 321 of the plugging member 32 is adaptively inserted into the disassembly slot 2b, the driving member 10 drives the coupling assembly 20 to rotate, the coupling assembly 20 drives the disassembly and assembly member 31 to rotate, the disassembly and assembly member 31 drives multiple plugging members 32 to rotate, and the multiple plugging members 32 drive the tool handle nut 2a to rotate around the axis of the tool handle body 2c through the cooperation relationship with the corresponding disassembly slot 2b, so as to loosen or lock the tool handle nut 2a relative to the tool handle body 2c, and further loosen or lock the tool 3. After loosening or locking the tool 3, the external robotic arm drives the entire disassembly and assembly mechanism 100 to move away from the tool handle 2 to facilitate the removal of the tool 3 on the tool handle 2 or the entire removal of the tool handle 2 locking the tool 3.

[0108] In this embodiment, the number of the disassembly slots 2b on the tool handle nut 2a can be four. Correspondingly, the number of the accommodating slots 312, the plugging members 32 and the elastic members 33 can also be four, so as to keep the torque applied by the disassembly and assembly mechanism 100 to the tool handle nut 2a balanced. Exemplarily, by controlling the rotation speed of the driving member 10, the locking torque of the tool handle nut 2a on the tool handle 2 can be controlled, for example, to be 30 N·m, etc. It can be understood that in other embodiments, the number of the accommodating slots 312, the plugging members 32 and the elastic members 33 can also be more or less, and can be specifically set adaptively according to the number of the disassembly slots 2b on the corresponding tool handle nut 2a. The present application does not make specific limitations on this.

[0109] In this embodiment, the coupling assembly 20 includes a first connecting member 22 and a second connecting member 23. The first connecting member 22 is connected to the driving member 10, and a plurality of clamping portions 221 protrude from the end of the first connecting member 22 facing away from the driving member 10. In this embodiment, the number of the clamping portions 221 can be two. An assembly hole 222 that is adapted to be connected to the output end 11 of the driving member 10 is further formed at one end of the first connecting member 22 where it is connected to the driving member 10. The driving member 10 is connected to the first connecting member 22 by inserting the output end 11 into the assembly hole 222. The second connecting member 23 is connected to the disassembly and assembly member 31. A receiving hole 21 is formed in the second connecting member 23, and a plurality of card slots 231 are formed at one end of the second connecting member 23 facing away from the disassembly and assembly member 31 and surrounding the receiving hole 21. In this embodiment, the number of the card slots 231 is four. Among them, the first connecting member 22 is in transmission connection with the second connecting member 23 by fitting and inserting two clamping portions 221 into two corresponding card slots 231. Thus, by setting the specific structure of the coupling assembly 20 as described above, the coupling assembly 20 has a simple structure and strong stability.

[0110] It can be understood that in other embodiments, the number of the clamping portions 221 can also be more, such as three, four, etc., and the number of the card slots 231 can also be more or less, such as two, three, five, six, etc. The embodiments of the present application do not make specific limitations in this regard.

[0111] In this embodiment, the disassembly and assembly assembly 30 further includes a plurality of embedding members 34. The plurality of embedding members 34 are respectively arranged in one-to-one correspondence with the plurality of receiving grooves 312. In this embodiment, the number of the embedding members 34 is four. Each embedding member 34 is adaptively arranged in the corresponding receiving groove 312 and is embedded and connected to the end of the corresponding elastic member 33 facing away from the corresponding plugging member 32, that is, the elastic member 33 is inserted into the corresponding embedding member 34. Thus, by setting the embedding members 34 as described above, when assembling the disassembly and assembly assembly 30, the embedding members 34, the elastic members 33 and the plugging members 32 can be modularly arranged first, and then the embedding members 34, the elastic members 33 and the plugging members 32 are integrally assembled in the receiving grooves 312, simplifying the assembly method of the disassembly and assembly assembly 30 and improving the assembly efficiency.

[0112] In this embodiment, the receiving groove 312 is generally T-shaped, and the plugging member 32 is also generally T-shaped. Thus, by setting the shapes of the receiving groove 312 and the plugging member 32 as described above, the plugging member 32 can be slidably arranged in the receiving groove 312, and the plugging member 32 can be prevented from sliding out of the receiving groove 312 under the elastic force of the elastic member 33, ensuring the stability of the disassembly and assembly assembly 30. It can be understood that in other embodiments, the receiving groove 312 can also be other shapes, such as trapezoidal, cross-shaped, etc. Correspondingly, the plugging member 32 is also generally trapezoidal, cross-shaped, etc. The present application does not make specific limitations in this regard.

[0113] In order to facilitate the connection between the second connecting member 23 and the disassembly and assembly member 31, in this embodiment, a flange 313 extending towards the coupling assembly 20 is provided on the periphery of the disassembly and assembly member 31. In this way, by providing the above-mentioned flange 313, it is convenient for the second connecting member 23 to be easily located within the area enclosed by the flange 313 when connecting with the disassembly and assembly member 31, and it is difficult for the second connecting member 23 to disengage from the disassembly and assembly member 31, making it convenient for the second connecting member 23 to connect with the disassembly and assembly member 31 and ensuring a stable connection between the second connecting member 23 and the disassembly and assembly member 31.

[0114] In order to enable the disassembly and assembly mechanism 100 to be smoothly separated from the tool handle 2, please refer to Figure 4 In this embodiment, the disassembly and assembly mechanism 100 further includes an elastic pressing assembly 40. The elastic pressing assembly 40 is rotatably connected to the disassembly and assembly member 31. The elastic pressing assembly 40 is used to elastically press the tool handle body 2c. When the disassembly and assembly mechanism 100 is separated from the tool handle 2, the elastic pressing assembly 40 applies an elastic force away from the disassembly and assembly component 30 to the tool handle body 2c, preventing the tool handle 2 from being lifted as a whole due to the plug 32 of the disassembly and assembly component 30 clamping the tool handle body 2c, and ensuring the smooth separation of the disassembly and assembly mechanism 100 from the tool handle 2.

[0115] Specifically, the elastic pressing assembly 40 includes an upper housing 41, a lower housing 42, a sliding member 43 and an elastic member 44. The upper housing 41 and the lower housing 42 are connected to form a receiving cavity 45. The sliding member 43 is slidably disposed in the receiving cavity 45. The elastic member 44 is located in the receiving cavity 45 and abuts between the upper housing 41 and the sliding member 43. In this embodiment, the number of elastic members 44 is four, and the four elastic members 44 respectively abut at the four corners of the sliding member 43. The elastic member 44 can be a spring. Among them, the disassembly and assembly member 31 is rotatably disposed on the upper housing 41. The elastic pressing assembly 40 is provided with a resisting hole 46 that penetrates through the upper housing 41, the lower housing 42 and the sliding member 43 and communicates with the central hole 311. The resisting hole 46 allows the tool handle nut 2a to pass through the elastic pressing assembly 40. The sliding member 43 elastically abuts against the tool handle body 2c under the elastic force of the elastic member 44. The resisting hole 46 is generally a stepped hole so that the sliding member 43 can abut against the tool handle body 2c.

[0116] Thus, by setting the specific structure of the elastic crimping component 40 above, when the disassembly and assembly mechanism 100 approaches the handle 2 of the assembly tool 3 as a whole, the disassembly and assembly mechanism 100 is relatively sleeved on the handle 2 and the tool 3 until the plug-in member 32 and the disassembly slot 2b on the handle nut 2a of the handle 2 are approximately in the same plane. At this time, the sliding member 43 abuts against the handle body 2c and is compressed by the elastic member 44 due to the reaction force of the handle body 2c. When the disassembly and assembly component 30 disassembles and assembles the tool 3 on the handle 2, the disassembly and assembly mechanism 100 moves away from the handle 2 of the assembly tool 3 as a whole. At this time, the elastic member 44 releases the elastic force to make the sliding member 43 abut against the handle body 2c, so that the plug-in portion 321 can be disengaged from the disassembly slot 2b, thereby enabling the disassembly and assembly mechanism 100 to be smoothly separated from the handle 2.

[0117] In order to enable the disassembly and assembly member 31 to be rotatably connected to the elastic crimping component 40, in this embodiment, the elastic crimping component 40 further includes a bearing member 47. The bearing member 47 includes an inner ring 471 and an outer ring 472 rotatably sleeved outside the inner ring 471. The inner ring 471 and the outer ring 472 are rotatably connected by balls. The bearing member 47 is located in the accommodation cavity 45, the outer ring 472 is connected to the upper housing 41, and one end of the disassembly and assembly member 31 facing away from the coupling component 20 passes through the upper housing 41 and is connected to the inner ring 471. Specifically, the bearing member 47 further includes an outer disc 473 connected to the side of the outer ring 472 facing away from the disassembly and assembly component 30 and an inner disc 474 connected to the side of the inner ring 471 facing away from the disassembly and assembly component 30. The outer disc 473 is connected to the upper housing 41, and the outer ring 472 is connected to the upper housing 41 through the outer disc 473. The inner disc 474 is connected to the disassembly and assembly member 31, and the disassembly and assembly member 31 is connected to the inner ring 472 through the inner disc 474, wherein the disassembly and assembly member 31 is generally a stepped structure. Thus, by setting the bearing member 47 above, the bearing member 47 is connected to the upper housing 41 to be fixed in the accommodation cavity 45, and the disassembly and assembly member 31 passes through the upper housing 41 and is connected to the bearing member 47, so that the disassembly and assembly member 31 is rotatably connected to the elastic crimping component 40.

[0118] In this embodiment, the upper housing 41 is provided with an upper through hole 411 which is generally a stepped hole. The upper through hole 411 is used to accommodate a part of the disassembly and assembly member 31 and enable the disassembly and assembly member 31 to pass through the upper housing 41. The lower housing 42 is provided with a lower through hole 421. The sliding member 43 is provided with a central hole 431 and a receiving groove 432 disposed around the central hole 431. The central hole 431 is generally a stepped structure. The diameter of the end of the central hole 431 close to the upper through hole 411 is larger than the diameter of the end of the central hole 431 far from the upper through hole 411. The receiving groove 432 is also used to accommodate the bearing member 47. Among them, the upper through hole 411, the central hole 431 and the lower through hole 421 form a resisting hole 46. Thus, by providing the above-mentioned upper through hole 411, lower through hole 421, central hole 431 and receiving groove 432, the elastic pressing assembly 40 can avoid the tool handle nut 2a and the tool 3 and resist the tool handle body 2c, and the sliding member 43 can accommodate the bearing member 47 to prevent interference between the bearing member 47 and the sliding member 43.

[0119] The disassembly and assembly mechanism 100 provided by the embodiment of the present application realizes the effect of mechanically and automatically disassembling and assembling the tool handle 2 through the cooperation of the driving member 10, the coupling assembly 20 and the disassembly and assembly assembly 30, replaces manual operation, reduces the labor intensity of the workers, improves the disassembly and assembly efficiency. In addition, the driving member 10 can control the torque of the disassembly and assembly member 31, so that the torque of the disassembly and assembly mechanism 100 is stable, and further improves the quality of clamping the tool 3 by the tool handle 2. The disassembly and assembly mechanism 100 further cooperates with the elastic pressing assembly 40, so that the disassembly and assembly mechanism 100 can be smoothly separated from the tool handle 2, ensuring the smooth progress of the disassembly and assembly operation.

[0120] Please refer to Figure 5 and Figure 6 , the embodiment of the present application also provides a disassembly and assembly device 1.

The disassembly and assembly device 1 includes a disassembly and assembly platform 200, a bearing assembly 300, a transfer mechanism 400, a mounting seat 500, a driving mechanism 600 and the disassembly and assembly mechanism 100 as described in the above embodiment. For the convenience of understanding and description, the embodiment of the present application defines the XYZ coordinate system as shown in Figure 5 and Figure 6 , wherein the first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction.

[0121] The disassembly and assembly platform 200 is used to install the bearing assembly 300, the transfer mechanism 400, the mounting seat 500, the drive mechanism 600 and the disassembly and assembly mechanism 100, so that the disassembly and assembly device 1 can be modularly set. In this embodiment, the disassembly and assembly platform 200 is roughly plate-shaped. It can be understood that in other embodiments, the disassembly and assembly device 1 can also include a cabinet (not shown) and a protective cover (not shown). For example, the cabinet is arranged below the disassembly and assembly platform 200, and power supply, electric control equipment, gas source and other devices can be arranged in the cabinet. The protective cover is arranged above the disassembly and assembly platform 200 and covers the bearing assembly 300, the transfer mechanism 400, the mounting seat 500, the drive mechanism 600 and the disassembly and assembly mechanism 100, so as to protect the bearing assembly 300, the transfer mechanism 400, the mounting seat 500, the drive mechanism 600 and the disassembly and assembly mechanism 100, so as to prevent the disassembly and assembly device 1 from causing harm to the operator and improve the protective performance of the disassembly and assembly device 1. It is understandable that a door opening for entering and exiting the handle 2 and the knife 3 may be provided on the protective cover, and buttons for controlling the start and stop of each mechanism may be provided on the protective cover, etc. The embodiments of the present application will not be described in detail here.

[0122] The bearing assembly 300 is slidably disposed on the disassembly and assembly platform 200 along a first direction, and the bearing assembly 300 is used to carry the knife handle 2. The transfer mechanism 400 is disposed on the disassembly and assembly platform 200 and connected to the bearing assembly 300, and the transfer mechanism 400 is used to drive the bearing assembly 300 to move. The mounting seat 500 is disposed on the disassembly and assembly platform 200. The driving mechanism 600 is disposed on the mounting seat 500 and is located on a side of the bearing assembly 300 away from the disassembly and assembly platform 200. The driving member 10 of the disassembly and assembly mechanism 100 is connected to the driving mechanism 600, so that the disassembly and assembly mechanism 100 moves close to the supporting assembly 300 under the drive of the driving mechanism 600, so that the disassembly and assembly member 31 is inserted into the tool handle 2, and the abutment plug-in member 32 is inserted into the tool handle nut 2a under the elastic force of the corresponding elastic member 33. The driving member 10 drives the coupling assembly 20 and the disassembly and assembly member 31 to rotate, and the disassembly and assembly member 31 drives multiple abutment plug-ins 32 to rotate. Multiple abutment plug-ins 32 drive the tool handle nut 2a to rotate through the corresponding abutment plug-ins 321 to disassemble and assemble the tool handle 2.

[0123] When disassembling and assembling the tool handle 2, the tool handle 2 of the assembled tool 3 is placed on the bearing assembly 300. The transfer mechanism 400 drives the bearing assembly 300, the tool handle 2 and the tool 3 to move below the disassembly and assembly mechanism 100. The driving mechanism 600 drives the disassembly and assembly mechanism 100 to approach the tool handle 2 and the tool 3, so that the tool handle 2 and the tool 3 pass through the resisting hole 46, the central hole 311 and the accommodating hole 21, such that the disassembly and assembly part 31 is sleeved on the tool handle 2 and the elastic pressing assembly 40 abuts against the tool handle body 2c. When the plug-in part 32 is aligned with the disassembly slot 2b on the tool handle nut 2a of the tool handle 2, the plug-in part 32 is inserted into the disassembly slot 2b of the tool handle nut 2a of the tool handle 2 under the elastic force of the elastic part 33. The driving part 10 drives the coupling assembly 20 to rotate, the coupling assembly 20 drives the disassembly and assembly part 31 to rotate, the disassembly and assembly part 31 drives a plurality of plug-in parts 32 to rotate, and the plurality of plug-in parts 32 drive the tool handle nut 2a to rotate, so as to loosen or lock the tool handle nut 2a, facilitating the loosening or locking of the tool 3. After the tool 3 is loosened or locked, the driving mechanism 600 drives the disassembly and assembly mechanism 100 to move away from the tool handle 2 and the tool 3, and the transfer mechanism 400 drives the bearing assembly 300, the tool handle 2 and the tool 3 to move in the reverse direction to the initial position, facilitating the removal of the loosened tool 3 on the tool handle 2 or the overall removal of the tool handle 2 with the locked tool 3.

[0124] In this embodiment, the number of the bearing assemblies 300 is two. The two bearing assemblies 300 are arranged at intervals in the second direction perpendicular to the first direction and are both connected to the transfer mechanism 400. The transfer mechanism 400 drives the two bearing assemblies 300 to move. Thus, by providing two bearing assemblies 300, the disassembly and assembly device 1 can perform loading and unloading on one side while disassembling and assembling the tool 3 on the other side, improving the disassembly and assembly efficiency.

[0125] Specifically, the driving mechanism 600 includes a lifting assembly 601, a connecting seat 602, and a transfer assembly 603. The mounting seat 500 includes a mounting plate 501 and two support frames 502. The two support frames 502 are arranged at intervals in the first direction on the disassembly and assembly platform 200 and are located on both sides of the transfer mechanism 400. The mounting plate 501 is connected between the two support frames 502 and is located above the disassembly and assembly platform 200 and the transfer mechanism 400. The driving mechanism 600 is arranged on the mounting plate 501. The lifting assembly 601 is slidably arranged on the mounting plate 501 of the mounting seat 500 in the second direction. The connecting seat 602 is connected to the lifting assembly 601 and is connected to the driving member 10. The transfer assembly 603 is arranged on the mounting plate 501 of the mounting seat 500 and is connected to the lifting assembly 601. The transfer assembly 603 is used to drive the lifting assembly 601 to move in the second direction. The lifting assembly 601 is used to drive the connecting seat 602 and the disassembly and assembly mechanism 100 to approach or move away from the bearing assembly 300 in a third direction perpendicular to both the first direction and the second direction. In this way, by setting the specific structures of the above driving mechanism 600 and the mounting seat 500, the transfer assembly 603 drives the lifting assembly 601, the mounting seat 500, and the disassembly and assembly mechanism 100 to move in the third direction between the two bearing assemblies 300, so that the disassembly and assembly mechanism 100 can be located above one of the bearing assemblies 300. The lifting assembly 601 drives the connecting seat 602 and the disassembly and assembly mechanism 100 to approach or move away from the corresponding bearing assembly 300 in the second direction, so that the disassembly and assembly mechanism 100 disassembles and assembles the tool 3 on the bearing assembly 300, improving the mechanization degree of the disassembly and assembly device 1.

[0127] In this embodiment, the transfer component 603 includes a power source 6031, a gear 6032, and a rack 6033. The power source 6031 can be a motor. The power source 6031 is disposed on the other side of the mounting plate 501 of the mounting seat 500, and the power source 6031 and the lifting component 601 are respectively located on opposite sides of the mounting plate 501 of the mounting seat 500.

Thus, by setting the specific structure of the transfer component 603 above, the power source 6031 drives the gear 6032 to rotate, the gear 6032 drives the rack 6033 to move in the second direction, and the rack 6033 drives the lifting component 601 to move in the second direction, so that the transfer component 603 drives the lifting component 601 to move in the second direction. The structure of the transfer component 603 is simple, thereby making the structure of the driving mechanism 600 compact and stable.

The transverse plate 6021 is sleeved and connected to the driving member 10 and the transverse plate 6021 is connected to the lifting component 601.

The two vertical plates 6022 are also respectively connected to the upper housing 41 of the elastic pressing component 40 and to the lifting component 601. Thus, by setting the specific structure of the connecting seat 602 above, the connection between the lifting component 601 and the disassembly and assembly mechanism 100 is stable, improving the stability of the disassembly and assembly device 1.

[0129] In this embodiment, the transfer mechanism 400 includes a power member 401, a transmission wheel 402, and a conveyor belt 403. The power member 401 can be a motor. The power member 401 is disposed on the disassembly and assembly platform 200. The number of the transmission wheels 402 is two and they are spaced apart in the first direction. The two transmission wheels 402 are both rotatably disposed on the disassembly and assembly platform 200. One of the two transmission wheels 402 is in transmission connection with the power member 401. The conveyor belt 403 is sleeved outside the two transmission wheels 402. The power member 401 drives the two transmission wheels 402 and the conveyor belt 403 to rotate. Among them, the two bearing components 300 are respectively located on both sides of the transfer mechanism 400 in the second direction, and the two bearing components 300 are both connected to the conveyor belt 403. Thus, by setting the specific structure of the transfer mechanism 400 above, the conveyor belt 403 is connected to both of the two bearing components 300. When the transfer mechanism 400 drives the two bearing components 300 to move, the two bearing components 300 present a "coming and going" movement scenario, which is beneficial to enabling the disassembly and assembly device 1 to perform loading and unloading on one side while disassembling and assembling the cutting tool 3 on the other side, improving the disassembly and assembly efficiency of the disassembly and assembly device 1.

[0130] In this embodiment, a support bar 201 extending in the first direction and a slide rail 202 disposed above the support bar 201 and extending in the first direction are provided on the disassembly and assembly platform 200.

In this way, by providing the above-mentioned slide rail 202 and load-bearing slider 303, the load-bearing assembly 300 is slidably arranged on the disassembly and assembly platform 200. By providing the above-mentioned belt buckle 302, the load-bearing assembly 300 is connected to the conveyor belt 403, so as to facilitate the transfer mechanism 400 to drive the load-bearing assembly 300 to move.

[0131] It can be understood that in other embodiments, the transfer mechanism 400 may further include two linear drive structures such as linear cylinders, linear telescopic rods, linear modules, etc. The two linear drive structures are respectively arranged in one-to-one correspondence with the two load-bearing assemblies 300. Each linear drive structure is used to independently drive the corresponding load-bearing assembly 300 to move. In this way, the transfer mechanism 400 can still drive the two load-bearing assemblies 300 to move.

[0132] It can be understood that the number of the load-bearing assemblies 300 can also be one. If the number of the load-bearing assemblies 300 is one, correspondingly, the drive mechanism 600 may include a lifting assembly 601 and a connecting seat 602 connected to each other.
