[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figure 1 and Figure 2As shown, the utility model provides a circuit breaker magnetic steel recovery device, including a frame 1, on which a workbench 12 is fixedly installed by bolts and nuts. A first disassembly mechanism 21 is fixedly provided on the frame 1 and the workbench 12, and the first disassembly mechanism 21 punches and removes the magnetic steel on the circuit breaker housing. A clamping mechanism 3 is fixedly provided on the frame 1 on one side of the first disassembly mechanism 21, and the clamping mechanism 3 cooperates with the first disassembly mechanism 21 to clamp and fix the circuit breaker housing. A recovery mechanism 4 is provided on the frame 1 below the workbench 12, and the recovery mechanism 4 recovers the magnetic steel punched and removed from the circuit breaker housing by the first disassembly mechanism 21. Protective plates 11 are fixedly provided on the frame 1 at both ends of the workbench 12, and the protective plates 11 have a blocking and protective function to prevent the staff from accidentally touching the inside of the device when the device is working and causing physical harm.

[0032] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, based on the above embodiment, the first disassembly mechanism 21 further includes a first cylinder 211, which is vertically fixed to the top of the frame 1 via screws. The end of the piston rod 2111 of the first cylinder 211 is fixedly mounted to a mounting bracket 212 via a nut. A tool holder 213 is fixedly mounted to the bottom of the mounting bracket 212 via screws. A punch 214 is fixedly mounted to the tool holder 213 via screws. The punch 214 has various shapes that match the shape of the magnet on the circuit breaker. A loading block 215 is fixedly mounted to the workbench 12 at a position corresponding to the tool holder 213 via screws. The loading block 215 is provided with a receiving cavity 2151, the shape of which matches the shape of the circuit breaker housing. A through slot 2152 is provided at the bottom of the accommodating chamber 2151, corresponding to the position of the magnet on the circuit breaker housing. A through slot 2152 is also provided on the workbench 12, corresponding to the position of the through slot 2152 at the bottom of the accommodating chamber 2151. The positions of the punch 214, the magnet, and the through slot 2152 correspond to each other, making it easier for the punch 214 to punch the magnet off the circuit breaker and eject it through the through slot 2152. A positioning block 2153 is fixedly installed within the accommodating chamber 2151. This positioning block 2153 helps quickly adjust the position of the circuit breaker placed in the accommodating chamber 2151, facilitating the subsequent clamping of the circuit breaker by the clamping mechanism 3.

[0033] like Figure 2 and Figure 5As shown, based on the above embodiment, the clamping mechanism 3 further includes a second cylinder 31, which is horizontally fixed to the side of the frame 1 via screws. The end of the piston rod 2111 of the second cylinder 31 is fixedly mounted with a connecting block 32 via screws. The end of the connecting block 32 near the carrier block 215 is fixedly mounted with a clamping block 33 via screws. A notch 2154 is provided at the end of the carrier block 215 near the clamping block 33, through which the clamping block 33 can enter the accommodating cavity 2151 of the carrier block 215. A guide rail 61 is fixedly mounted on the frame 1 via screws, and a slider 62 is fixedly mounted at the bottom of the connecting block 32 via screws. The slider 62 is slidably connected to the guide rail 61, and the slider 62 cooperates with the guide rail 61 to improve the accuracy of the movement of the clamping block 33. The clamping mechanism 3 can clamp and secure the circuit breaker placed in the accommodating cavity 2151.

[0034] like Figure 2 and Figure 3 As shown, based on the above embodiment, the frame 1 is further provided with a guide assembly 6 along the direction of movement of the piston rod 2111 of the first cylinder 211. The guide assembly 6 includes a guide rail 61, which is fixed to the frame 1 via screws. A slider 62 is slidably mounted on the guide rail 61 and slides along the guide rail 61. The slider 62 is fixedly connected to the mounting frame 212 via screws. The guide assembly 6 guides the up and down movement of the mounting frame 212, improving the precision of the punch 214 during operation.

[0035] like Figure 2 and Figure 4 As shown, based on the above embodiment, the recovery mechanism 4 further includes a recovery box 42, which is placed on the frame 1 below the loading block 215. When the recovery box 42 is full of magnets, it can be replaced with another empty recovery box 42. A guide plate 41 is fixed to the bottom of the workbench 12 at the position corresponding to the loading block 215 via screws. The guide plate 41 is tilted toward the recovery box 42. When the magnets fall out of the through slot 2152, they slide along the guide plate 41 into the recovery box 42.

[0036] like Figure 1 、 Figure 2 and Figure 4As shown, based on the above embodiment, a second disassembly mechanism 22 is further fixedly mounted on the frame 1 and the workbench 12. The second disassembly mechanism 22 is symmetrically arranged with the first disassembly mechanism 21 about the center of the frame 1. The symmetrical arrangement of the first and second disassembly mechanisms 21, 22 allows for simultaneous removal of the magnets on two circuit breakers, improving disassembly efficiency. A first start button 51 is fixedly mounted on one end of the frame 1 near the workbench 12, while a second start button 52 and an emergency stop button 53 are fixedly mounted on the other end of the frame 1 near the workbench 12. The first start button 51, the second start button 52, and the emergency stop button 53 are all electrically connected to the first and second disassembly mechanisms 21, 22. The first start button 51, the second start button 52, and the emergency stop button 53 are all electrically connected to the clamping mechanism 3. The clamping mechanism 3, the first and second disassembly mechanisms 21, 22 only activate when the first start button 51 and the second start button 52 are pressed simultaneously. This prevents a worker from accidentally activating the first and second disassembly mechanisms 21, 22, thereby improving the safety of the device. The emergency stop button 53 is used to stop the device in an emergency to ensure the safety of the device.

[0037] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, there are various types of discarded circuit breakers, such as the first circuit breaker housing 71 and the second circuit breaker housing 72, whose magnetic steel needs to be removed. Specifically, the magnetic steel on the first circuit breaker housing 71 is a circular magnetic steel 712, and the magnetic steel on the second circuit breaker housing 72 is a sector-shaped magnetic steel 721. When the circular magnetic steel 712 on the first circuit breaker housing 71 needs to be removed, the punch 214 can be replaced with a corresponding circular punch 214. When the sector-shaped magnetic steel 721 on the second circuit breaker housing 72 needs to be removed, the punch 214 can be replaced with a corresponding sector-shaped punch 214. Both the first circuit breaker housing 71 and the second circuit breaker housing 72 have grooves 711, which cooperate with the positioning blocks 2153 in the accommodating cavity 2151 to quickly position the first circuit breaker housing 71 and the second circuit breaker housing 72.

[0038] like Figures 1 to 7As shown, during operation, (1) the staff places the two first circuit breaker housings 71 in the accommodating cavities 2151 of the loading blocks 215 of the first disassembly mechanism 21 and the second disassembly mechanism 22 respectively with bare hands, and then the staff leaves the loading block 215 with both hands. (2) Then, the staff presses the first start button 51 and the second start button 52 with both hands at the same time, and the clamping mechanism 3 works. The second cylinder 31 pushes the connecting block 32 toward the loading block 215 through the piston rod 2111, and the connecting block 32 drives the clamping block 33 to move. When the clamping block 33 enters the notch 2154 of the loading block 215 and rests on the side of the first circuit breaker housing 71, the first circuit breaker housing 71 is clamped and fixed by the cooperation between the clamping block 33 and the accommodating cavity 2151; then, the second circuit breaker housing 71 is clamped and fixed. The first disassembly mechanism 21 and the second disassembly mechanism 22 are working, and the piston rod 2111 of the first cylinder 211 pushes the punch 214 to move toward the loading block 215. After the punch 214 enters the accommodating chamber 2151, it contacts the circular magnet 712 on the first circuit breaker. At the same time, the punch 214 continues to move downward to flush the circular magnet 712 from the first circuit breaker. The circular magnet 712 that falls from the first circuit breaker enters the guide plate 41 through the through groove 2152 and slides along the guide plate 41 into the recycling box 42. (3) Finally, the first disassembly mechanism 21, the second disassembly mechanism 22 and the clamping mechanism 3 are automatically reset, and the staff respectively removes the first circuit breaker housing 71 from the accommodating chamber 2151 of the loading block 215 of the first disassembly mechanism 21 and the second disassembly mechanism 22, completing the working process of the circuit breaker magnet recovery device.

Those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and purpose of the present invention, all of which are intended to fall within the scope of protection of the present invention.
