Description

Technical Field

[0001] This invention relates to the field of waste bearing recycling, specifically to a waste bearing dismantling device and method. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. They are mainly divided into two categories: sliding bearings and rolling bearings. Sliding bearings consist of three parts: rings, rolling elements, and cage. The rings are further divided into outer rings and inner rings. The rolling elements convert sliding friction into rolling friction by rolling between the inner and outer rings. Its main function is to support the rotating parts of the machine, reduce the coefficient of friction during its movement, and ensure its rotational accuracy.

[0003] The main reasons for the scrapping of discarded bearings include deformation, cracking, and wear of the raceway surface. During dismantling, depending on the degree of damage, some less damaged parts can be repaired and re-enter the market, while more severely damaged parts can be crushed and smelted to be recycled into industrial steel and used to manufacture new bearings or mechanical parts. During the bearing dismantling process, different parts have different materials and reuse values, so it is necessary to first test their integrity before targeted recycling. For this reason, we have proposed a dismantling equipment and method for discarded bearings. Summary of the Invention

Both the chamber and the upper end of the ultrasonic cleaning chamber are provided with grooves adapted to the bearing size.

[0010] Furthermore, the raceway detection unit includes a support platform, on one end of the upper surface of the support platform a telescopic platform A is fixedly installed, and a rotating disk is fixedly installed on the movable end of the telescopic platform A. A chuck B is provided at the center of the rotating disk, and several telescopic support blocks C are provided on the outer wall of the chuck B. A driven disk is engaged with the outer wall of the rotating disk, and an inner wheel is provided at the center of the driven disk. The upper end of the inner wheel protrudes from the upper surface of the support platform. The chuck B is used to drive the inner ring of the bearing to rotate, and the inner wheel is used to drive the outer ring of the bearing to rotate.

[0011] Furthermore, the raceway detection unit also includes two mounting plates, with a vision camera A fixedly mounted on the inner side of each of the two mounting plates. Light sources are fixedly mounted on both sides of the vision camera A on the inner wall of each mounting plate, and the two light sources illuminate the raceways of the outer and inner rings of the bearing, respectively.

[0012] Furthermore, the bearing separation unit includes a separation box, with an inclined conveyor belt at the upper end of the separation box. Baffles are provided at both ends of the conveyor belt, and a Y-shaped dividing belt is provided below the notch of the baffles. A movable plate is rotatably connected to one end of the Y-shaped dividing belt. The movable plate is used to control the bearing flow direction. The bearing separation unit also includes a bearing splitting mechanism, which includes two support plates. One end of each support plate is fixedly connected to the inner wall of the separation box, and a motor is fixedly installed on the upper end of each support plate. The output end of the motor is fixedly... A movable platform is fixedly installed. A telescopic rod B is fixedly installed at the lower end of the movable platform. A pad is fixedly installed at the movable end of the telescopic rod B. A baffle is fixedly connected to the bottom of the pad. A telescopic rod C is fixedly installed at the top of the pad. A movable plate is fixedly connected to the movable end of the telescopic rod C. A clamping column is fixedly connected to the lower end of the movable plate. Storage boxes are provided on both sides of the Y-shaped material distribution belt inside the separation box. A conveyor line is provided on one side of the storage box inside the separation box. A buffer plate is also provided at the end of the Y-shaped material distribution belt near the conveyor line.

[0013] Furthermore, one end of the conveyor line extends obliquely upward from inside the separation box and exits horizontally from inside the separation box. A separation conveyor line is set on the side of the conveyor line outside the separation box. Several vision cameras B and telescopic rods D are fixedly installed on one side of the separation conveyor line. A pusher plate is fixedly connected to the movable end of the telescopic rod D. The shape of the pusher plate is approximately L-shaped. The surface of the conveyor line belt is provided with concave holes. The inner wall of the conveyor line is provided with auxiliary transmission belts and fixed belts at intervals below the concave holes of the belt. The auxiliary transmission belts and fixed belts are used to control the balls to rotate downward in different directions within the concave holes.

[0014] The present invention also includes a method for dismantling discarded bearings, comprising the following steps: Step S1: Place the bearing to be disassembled with the cage screw side facing down on the conveyor line, and it will be conveyed by the conveyor line to the underside of the robotic arm A; Step S2: The robotic arm A controls the movable end of the telescopic arm A to extend downward until the chuck A enters the inner side of the bearing inner ring. Then the telescopic support block A extends out from the chuck A and abuts against the inner ring of the bearing. The rotating arm rotates. At this time, the robotic arm A can be under the top plate, controlled by the guide rail, passing through the groove at the outer end of the box, and carrying the bearing into the inner side of the box. Step S3: After robotic arm A reaches the set position, the movable ends of the two telescopic rods A move towards the bearing cage simultaneously, so that the suction head at the front end of the telescopic rod A presses against the surface of the cage. The suction head holds the cage through the connected pipe and air compressor. At this time, the electric screwdriver begins to remove the screws on the surface of the cage with the cooperation of the rotary table, the primary telescopic arm and the secondary telescopic arm. After the screws are removed, the telescopic rod A controls the suction head to remove the two cage pieces from both sides of the bearing. During the process, the cage on the side closer to robotic arm A is cut off by hydraulic pliers. After the cage is removed, robotic arm B controls its telescopic arm B to descend. The front end of the lateral telescopic arm is inserted into the upper gap between the inner and outer rings of the bearing. Then the telescopic support block B extends outward to fix the upper gap between the inner and outer rings. Step S4: After the cage is removed, the bearing is lifted by robotic arm B, and the telescopic support block A on robotic arm A retracts. After robotic arm B controls the bearing displacement through the lateral telescopic arm, robotic arm A can detach from the bearing and return to the conveyor line to wait for the next bearing to arrive. The bearing carried by robotic arm B then enters the ultrasonic cleaning box, which contains water-based cleaning agent and <5% butyl solvent. The heating unit heats the solvent to 60-70℃, the ultrasonic frequency is 40-80 kHz, and the cleaning time is 10-15 minutes to remove oil stains from the bearing surface. After cleaning, robotic arm B carries the bearing to the drying area for drying. Step S5: The dried bearing is carried by robotic arm B to the raceway inspection unit. Robotic arm B controls the inner ring of the bearing to fit onto the outside of chuck B. Then, the telescopic support block C on the surface of chuck B extends to fix the inner ring of the bearing. Then, the rotating wheel rotates under the action of the internal motor, causing chuck B to drive the inner ring of the bearing to rotate. During the process, the meshing of the driven plate and the rotating wheel causes the inner wheel to drive the outer ring of the bearing to start rotating as well. The light sources on both sides illuminate the raceway of the outer ring and the inner ring respectively. The vision camera A performs defect detection on the raceway and the surface of the raceway while the outer and inner rings are rotating, and distinguishes between recyclable and non-recyclable raceways. Step S6: The inspected bearing is carried by the robotic arm B to the inclined conveyor belt. When the robotic arm B lowers the bearing onto the conveyor belt, the telescopic support block B at one end of the robotic arm B and the lateral telescopic arm retract in sequence, so that the robotic arm B is no longer in contact with the bearing. At this time, the conveyor belt starts and carries the bearing to the Y-shaped distribution belt. The Y-shaped distribution belt controls the rotation of the movable plate under the action of the internal motor according to whether the bearing is recyclable or not, and adjusts the flow direction of the bearing on the surface of the Y-shaped distribution belt. Step S7: The Y-shaped material distribution belt transports the bearing to the bearing splitting mechanism. During splitting, the telescopic rod B controls the pad and the movable plate to descend. During this process, the clamping column on the lower side of the movable plate enters the inner side of the inner ring. The telescopic rod C starts and controls the clamping column to move closer to the baffle. Finally, the outer ring of the bearing is pressed against the baffle. The clamping column and the baffle clamp the inner and outer rings of the bearing respectively. At this time, there is enough clearance at the end of the bearing away from the clamping point for the balls to slide down. After the telescopic rod B controls the pad to lift, the motor controls the pad to swing, dropping the balls onto the surface of the Y-shaped material distribution belt. The Y-shaped material distribution belt continues to transport the clamped rings. After the balls are cleaned, the motor controls the pad to swing to the outside of the Y-shaped material distribution belt, and then the clamping is released and the rings enter the storage box. Step S8: After falling, the balls on the surface of the Y-shaped separating belt are buffered and guided by the buffer plate and then enter the conveying line. The conveying line passes through the concave holes on the surface corresponding to the size of the balls and conveys the balls through the opening of the separation box to the outside of the separation box. The separation conveying lines arranged on both sides of the conveying line use vision camera B to complete the surface defect detection of the balls. The pusher plate pushes the balls with defects to the separation conveying line.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this solution, a movable rotating disk is set up. The rotating disk rotates under the action of an internal motor, causing the chuck B to drive the inner ring of the bearing to rotate. During the process, the driven disk meshes with the rotating disk, causing the inner wheel to drive the outer ring of the bearing to start rotating as well. The light sources on both sides illuminate the raceway of the outer ring and the inner ring respectively. The vision camera A performs defect detection on the raceway and the surface of the ring while the outer and inner rings are rotating, distinguishing between recyclable and non-recyclable rings. The movable end of the telescopic rod D is fixedly connected to a pusher plate, which is approximately L-shaped with its front end extending onto the conveyor line. After detection, it can push the corresponding ball onto the separation conveyor line. The surface of the conveyor belt is provided with recessed holes for the conveyor belt to carry the ball. The size of the recessed holes is not larger than the size of the ball. The inner wall of the conveyor belt is provided with auxiliary drive belts and fixed belts at intervals below the recessed holes of the belt. When the ball passes by, the auxiliary drive belts and fixed belts contact the bottom of the ball to control the ball to rotate in different directions within the recessed holes.

[0018] 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.

[0019] A dismantling device for discarded bearings, such as Figure 1-9The diagram shows a conveyor line 1. On one side of the conveyor line 1 is a disassembly and cleaning unit 2 for removing the cage and cleaning and drying the bearing. On one side of the disassembly and cleaning unit 2 is a raceway detection unit 3. On one side of the raceway detection unit 3 is a raceway separation unit 4 for separating the raceway and balls and classifying recyclable and non-recyclable raceways for recycling. On one side of the raceway separation unit 4 is a ball separation unit 5 for classifying recyclable and non-recyclable balls for recycling.

[0020] The disassembly and cleaning unit 2 includes a moving mechanism 6, a disassembly mechanism 7, and a cleaning mechanism 8. The moving mechanism 6 includes a robotic arm A9 and a robotic arm B10. Both robotic arms A9 and B10 are located on the lower surface of the top plate 11. The lower surface of the top plate 11 is provided with two guide rails corresponding to robotic arms A9 and B10. The tops of robotic arms A9 and B10 are fixedly installed on the movable ends of the corresponding guide rails. The guide rails are used for the lateral movement of robotic arms A9 and B10, and the length of the guide rails is adapted to the required movement path length of robotic arms A9 and B10.

[0021] It should be noted that robotic arm A9 includes a telescopic arm A12, the movable end of which is rotatably connected to a rotating arm 13. A locking head A14 is located at the bottom of the rotating arm 13, and three sets of telescopic support blocks A15 are provided on the outer wall of the locking head A14. Robotic arm B10 includes a telescopic arm B16, the movable end of which is fixedly mounted with a transverse telescopic arm 17. Telescopic support blocks B18 are provided at the upper and lower ends of the outer wall of the movable end of the transverse telescopic arm 17. The movable end dimension of the transverse telescopic arm 17 is smaller than the ball bearing dimension. The surface of the telescopic support block B18 is a smooth surface to accommodate the rotation of the bearing. When the bearing rotates, the telescopic support block… B18 can also retract slightly, loosening the fixation on the bearing without causing it to fall off and break apart; the telescopic arm A12, telescopic support block A15, and similar telescopic elements are all electric telescopic rods, and the rotating arm 13 is also driven to rotate by a motor located on one side of the movable end of the telescopic arm A12, with a rotation angle of ninety degrees. The outer surface of the telescopic support block A15 is provided with a rubber pad to increase the friction between it and the inner ring, making the fixation of the bearing by the robotic arm A9 more stable. In the robotic arm B10, the telescopic arm B16 controls the change of the vertical height of the lower end of the robotic arm B10, and the horizontal telescopic arm 17 controls the adjustment of its movable end in the horizontal plane.

[0022] Specifically, the disassembly mechanism 7 includes a housing 19. Telescopic rods A20 are fixedly installed on both inner walls of the housing 19. Suction heads 21 are provided at the movable ends of the telescopic rods A20. A rotating table 22 is fixedly installed on the inner wall of the housing 19 away from the conveyor line 1. A primary telescopic arm 23 is fixedly installed at one end of the rotating table 22 near the middle of the housing 19. A secondary telescopic arm 24 is fixedly installed at the movable end of the primary telescopic arm 23. An electric screwdriver 25 is fixedly installed at the movable end of the secondary telescopic arm 24. A hydraulic clamp 26 is fixedly installed on the inner wall of the housing 19 away from the primary telescopic arm 23. The hydraulic clamp 26 has two jaws for cutting at that location. The retainer at the end detaches from the surface of the robotic arm A9; the inside of the housing 19 is filled with liquid so that the retainer will not hit the bottom of the housing 19 when it falls. One end of the suction head 21 is connected to the suction pipe and the air compressor suction end, respectively, and sucks up the retainer. The suction end at the front end of the suction head 21 can suction at multiple points to fix the retainer. When removing the screws on the surface of the retainer, the rotary table 22 is controlled to rotate by the output end of the motor inside the equipment. The electric screwdriver 25 is adjusted to align with the screws in different positions. The primary telescopic arm 23 and the secondary telescopic arm 24 are used to control the overall distance between the electric screwdriver 25 and the retainer, and the distance between the electric screwdriver 25 and the screws on the retainer, respectively.

[0023] It is understood that the cleaning mechanism 8 includes an ultrasonic cleaning box 27. The ultrasonic cleaning box 27 is existing technology, so it will not be described in detail. The ultrasonic cleaning box 27 is equipped with a heating unit inside, which heats the solvent inside the ultrasonic cleaning box 27 by electric heating. The inner wall of the box body 19 is provided with a drying area 28 on the side of the ultrasonic cleaning box 27 away from the robotic arm A9. The upper end of both the box body 19 and the ultrasonic cleaning box 27 is provided with a groove adapted to the size of the bearing, so that the robotic arm A9 and the robotic arm B10 carrying the bearing and the bearing can pass through. The drying area 28 specifically includes a vent in the area. One end of the vent is connected to a blower pipe and a corresponding hot air blower. The hot air in the hot air blower can be electrically heated. It should be added that the bottom of the ultrasonic cleaning box 27 is provided with a drain port and a replenishment port, which are controlled by a solenoid valve. After cleaning, the solution can be distilled or left to stand, and some of the lubricating oil or solvent can be recovered.

[0024] The raceway detection unit 3 includes a support platform 29. A telescopic platform A30 is fixedly installed on one end of the upper surface of the support platform 29. A rotating disk 31 is fixedly installed on the movable end of the telescopic platform A30. A chuck B32 is provided at the center of the rotating disk 31. Several telescopic support blocks C33 are provided on the outer wall of the chuck B32. A driven disk 34 is engaged with the outer wall of the rotating disk 31. An inner wheel 35 is provided at the center of the driven disk 34. The upper end of the inner wheel 35 protrudes from the upper surface of the support platform 29. The chuck B32 is used to drive the inner ring of the bearing to rotate, and the inner wheel 35 is used to drive the outer ring of the bearing to rotate. The rotating disk 31 is driven to rotate by a corresponding motor inside the equipment. After the telescopic support block C33 extends out of the fixed inner ring, the engagement of the rotating disk 31 with the driven disk 34 causes the inner wheel 35 to rotate, driving the outer ring of the bearing to rotate.

[0025] To avoid blind spots in the inspection, the raceway inspection unit 3 also includes two mounting plates 36. A vision camera A37 is fixedly mounted on the inner side of each mounting plate 36. Light sources 38 are fixedly mounted on both sides of the vision camera A37 on the inner wall of the mounting plate 36. The two light sources 38 illuminate the raceways of the outer and inner rings of the bearing, respectively. The two vision cameras A37 are also located on both sides of the bearing, acquiring images of the two halves of the raceway. Defects that may exist on the metal surface will be reflected in the images to varying degrees. Through specialized image inspection software, preset conditions are set, defects are judged, and they are classified.

[0026] To separate and classify recyclable and non-recyclable bearings, the bearing separation unit 4 includes a separation box 39. An inclined conveyor belt 40 is installed at the upper end of the separation box 39. Baffles are installed at both ends of the conveyor belt 40. A Y-shaped dividing belt 41 is installed below the notch of the baffles. A movable plate 42 is rotatably connected to one end of the Y-shaped dividing belt 41. The movable plate 42 is used to control the flow direction of the bearings. The bearing separation unit 4 also includes a bearing splitting mechanism 43. The bearing splitting mechanism 43 includes two support plates 44. One end of each support plate 44 is fixedly connected to the inner wall of the separation box 39. A motor 45 is fixedly installed on the upper end of each support plate 44. A movable platform 46 is fixedly installed at the output end of the motor 45.

A telescopic rod C50 is fixedly installed on the top of the baffle plate 49 and the pad plate 48. The movable end of the telescopic rod C50 is fixedly connected to the movable plate 51, and the lower end of the movable plate 51 is fixedly connected to the clamping column 52. The inside of the separation box 39 has storage boxes 53 on both sides of the Y-shaped material distribution belt 41. The ends of the Y-shaped material distribution belt 41 are two independent conveyor belts. On the side of the two conveyor belts that are close to each other, the Y-shaped material distribution belt 41 is provided with an upward-curving slide. The upper end of the slide extends to the notch of the baffle of the conveyor belt 40. The bearing at the notch enters the slide and is then controlled by the movable plate 42 to enter different conveyor belts. The movable plate 42 is controlled to rotate by the motor at the bottom of the slide. It should also be noted that the separation box 39 is filled with liquid so that the bearings and balls will not have high-speed impacts during separation and falling, making the equipment safer.

[0027] It should be added that the ball separation unit 5 includes a conveyor line 54. The conveyor line 54 is located inside the separation box 39 on one side of the storage box 53. A buffer plate 55 is also provided at one end of the Y-shaped distribution belt 41 near the conveyor line 54. One end of the conveyor line 54 extends obliquely upwards from inside the separation box 39 to detach from the water surface and exits horizontally from inside the separation box 39. A separation conveyor line 56 is located on the side of the conveyor line 54 outside the separation box 39 to store the screened balls. Several vision cameras B57 and telescopic rods D58 are fixedly installed on one side of the separation conveyor line 56. The surface light source of the separation conveyor line 56 is not shown in the diagram. A pusher plate 59 is fixedly connected to the movable end of the telescopic rod D58. The pusher plate 59 is approximately L-shaped, with its front end extending onto the conveyor line 54. After ball detection, it can pull the corresponding ball onto the separation conveyor line 56. The surface of the conveyor line 54 has recessed holes 60 for the conveyor line 54 to carry the balls. The size of the recess 60 is no larger than the size of the ball. The inner wall of the conveyor line 54 is provided with an auxiliary drive belt 61 and a fixed belt 62 at intervals below the recess 60 of the belt body. The auxiliary drive belt 61 is located below the recess 60 and is driven by a motor, moving in different directions from the conveyor line 54. The fixed belt 62 is fixed below the conveyor line 54. When the ball passes through, the auxiliary drive belt 61 and the fixed belt 62 contact the bottom of the ball to control the ball to rotate in different directions within the recess 60.

[0028] The present invention also includes a method for dismantling discarded bearings, comprising the following steps: Step S1: Place the bearing to be disassembled, with the cage screw side facing down, on conveyor line 1, and convey it to the underside of robotic arm A9 by conveyor line 1; Step S2: The robotic arm A9 controls the movable end of the telescopic arm A12 to extend downward until the clamp A14 enters the inner side of the bearing inner ring. Then the telescopic support block A15 extends out from the clamp A14 and abuts against the inner ring of the bearing. The rotating arm 13 rotates. At this time, the robotic arm A9 can pass through the groove at the outer end of the box 19 under the top plate 11, controlled by the guide rail, and carry the bearing into the inner side of the box 19. Step S3: After the robotic arm A9 reaches the set position, the movable ends of the two telescopic rods A20 simultaneously move closer to the bearing cage, so that the suction head 21 at the front end of the telescopic rod A20 presses against the surface of the cage. The suction head 21 sucks the cage through the connected pipe and the air compressor. At this time, the electric screwdriver 25 begins to remove the screws on the surface of the cage with the cooperation of the rotary table 22, the primary telescopic arm 23 and the secondary telescopic arm 24. After the screws are removed, the telescopic rod A20 controls the suction head 21 to remove the two cage pieces from both sides of the bearing. During the process, the cage on the side closer to the robotic arm A9 is cut by the hydraulic clamp 26. After the cage is removed, the robotic arm B10 controls its telescopic arm B16 to descend. The front end of the lateral telescopic arm 17 is inserted into the upper gap between the inner and outer rings of the bearing. Then the telescopic support block B18 extends outward to fix the upper gap between the inner and outer rings. Step S4: After the cage is removed, the bearing is lifted by the robotic arm B10. The telescopic support block A15 on the robotic arm A9 retracts. After the robotic arm B10 controls the bearing displacement through the lateral telescopic arm 17, the robotic arm A9 can detach from the bearing and return to the conveyor line 1 to wait for the next bearing to arrive. The bearing carried by the robotic arm B10 then enters the ultrasonic cleaning box 27. The ultrasonic cleaning box 27 contains water-based cleaning agent and <5% butyl solvent. The heating unit heats the solvent to 60-70℃, the ultrasonic frequency is 40-80 kHz, and the cleaning time is 10-15 minutes to clean the oil stains on the bearing surface. After cleaning, the robotic arm B10 carries the bearing to the drying area 28 for drying. Step S5: The dried bearing is carried by the robotic arm B10 to the raceway detection unit 3. The robotic arm B10 controls the bearing inner ring to fit onto the outside of the chuck B32. Then, the telescopic support block C33 on the surface of the chuck B32 extends to fix the bearing inner ring. Then, the rotating wheel 31 rotates under the action of the internal motor, causing the chuck B32 to drive the bearing inner ring to rotate. During the process, the driven plate 34 meshes with the rotating wheel 31, causing the inner wheel 35 to drive the bearing outer ring to start rotating as well. The light sources 38 on both sides illuminate the raceway of the outer ring and the inner ring respectively. The vision camera A37 performs defect detection on the raceway and the surface of the raceway while the outer and inner rings are rotating, and distinguishes between recyclable and non-recyclable raceways. Step S6: The inspected bearing is carried by the robotic arm B10 to the inclined conveyor belt 40. When the robotic arm B10 lowers the bearing onto the conveyor belt 40, the telescopic support block B18 and the transverse telescopic arm 17 at one end of the robotic arm B10 retract in sequence, so that the robotic arm B10 is no longer in contact with the bearing. At this time, the conveyor belt 40 starts and carries the bearing to the Y-shaped distribution belt 41. The Y-shaped distribution belt 41 controls the movable plate 42 to rotate under the action of the internal motor according to whether the bearing is recyclable or not, and adjusts the flow direction of the bearing on the surface of the Y-shaped distribution belt 41. Step S7: The Y-shaped material distribution belt 41 transports the bearing to the bearing splitting mechanism 43. During splitting, the telescopic rod B47 controls the pad 48 and the movable plate 51 to descend. During the process, the clamping column 52 on the lower side of the movable plate 51 enters the inner side of the inner ring. The telescopic rod C50 is activated, controlling the clamping column 52 to move closer to the baffle 49. Finally, the outer ring of the bearing is pressed against the baffle 49. The clamping column 52 and the baffle 49 clamp the inner and outer rings of the bearing respectively. At this time, there is enough clearance at the end of the bearing away from the clamping point for the balls to slide down. After the telescopic rod B47 controls the pad 48 to lift, the motor 45 controls the pad 48 to swing, dropping the balls onto the surface of the Y-shaped material distribution belt 41. The Y-shaped material distribution belt 41 continues to transport the clamped rings. After the balls are cleaned, the motor 45 controls the pad 48 to swing to the outside of the Y-shaped material distribution belt 41, and then the clamping is released and the rings enter the storage box 53. Step S8: After falling, the balls on the surface of the Y-shaped separating belt 41 are buffered and guided by the buffer plate 55 and then enter the conveying line 54. The conveying line 54 passes through the concave holes 60 corresponding to the size of the balls and conveys the balls through the opening of the separating box 39 to the outside of the separating box 39. The separating conveying lines 56 arranged on both sides of the conveying line 54 use vision cameras B57 to detect surface defects of the balls. The pusher plate 59 pushes the defective balls to the separating conveying line 56. In this embodiment, it should be added that the detected balls or rings can be further inspected in the future. The bearings to be inspected are not large bearings, and the balls to be inspected are spherical balls.

8. A method for dismantling discarded bearings, characterized in that, The dismantling device for discarded bearings as described in claim 7 includes the following steps: Step S1: Place the bearing to be disassembled with the cage screw side facing down on the conveyor line (1), and convey it to the underside of the robotic arm A (9) by the conveyor line (1); Step S2: The robotic arm A (9) controls the movable end of the telescopic arm A (12) to extend downward until the clamp A (14) enters the inner side of the bearing inner ring. Then the telescopic support block A (15) extends out from the clamp A (14) and abuts against the bearing inner ring. The rotating arm (13) rotates. At this time, the robotic arm A (9) can pass through the groove at the outer end of the box (19) under the top plate (11) and be controlled by the guide rail to carry the bearing into the inner side of the box (19). Step S3: After the robotic arm A (9) reaches the set position, the moving ends of the two telescopic rods A (20) move towards the bearing cage at the same time, so that the suction head (21) at the front end of the telescopic rod A (20) presses against the surface of the cage. The suction head (21) sucks the cage through the connected pipe and the air compressor. At this time, the electric screwdriver (25) starts to remove the screws on the surface of the cage with the cooperation of the rotary table (22), the primary telescopic arm (23) and the secondary telescopic arm (24). After the screws are removed, the telescopic rod A (20) controls the suction head (21) to remove the two cages from both sides of the bearing. During the process, the cage on the side closer to the robotic arm A (9) is cut by the hydraulic clamp (26). After the cage is removed, the robotic arm B (10) controls its telescopic arm B (16) to descend. The front end of the lateral telescopic arm (17) is inserted into the upper gap between the inner and outer rings of the bearing. Then the telescopic support block B (18) extends outward to fix the upper gap between the inner and outer rings. Step S4: After the cage is removed, the bearing is lifted by the robotic arm B (10), and the telescopic support block A (15) on the robotic arm A (9) retracts. After the robotic arm B (10) controls the bearing displacement through the horizontal telescopic arm (17), the robotic arm A (9) can detach from the bearing and return to the conveyor line (1) to wait for the next bearing to arrive. The bearing carried by the robotic arm B (10) then enters the ultrasonic cleaning box (27). The ultrasonic cleaning box (27) contains water-based cleaning agent and <5% butyl solvent. The heating unit heats the solvent to 60-70℃, the ultrasonic frequency is 40-80 kHz, and the cleaning time is 10-15 minutes to clean the oil stains on the bearing surface. After cleaning, the bearing is carried by the robotic arm B (10) to the drying area (28) for drying. Step S5: The dried bearing is carried by the robotic arm B (10) to the raceway detection unit (3). The robotic arm B (10) controls the inner ring of the bearing to be fitted onto the outside of the chuck B (32). Then, the telescopic support block C (33) on the surface of the chuck B (32) extends to fix the inner ring of the bearing. Then, the rotating wheel (31) rotates under the action of the internal motor, causing the chuck B (32) to drive the inner ring of the bearing to rotate. During the process, the meshing of the driven plate (34) with the rotating wheel (31) causes the inner wheel (35) to drive the outer ring of the bearing to start rotating as well. The light sources (38) on both sides illuminate the raceway of the outer ring and the inner ring respectively. The vision camera A (37) performs defect detection on the raceway and the surface of the ring under the rotating state of the outer and inner rings, and distinguishes between recyclable and non-recyclable rings. Step S6: The inspected bearing is carried by the robotic arm B (10) to the inclined conveyor belt (40). When the robotic arm B (10) lowers the bearing onto the conveyor belt (40), the telescopic support block B (18) at one end of the robotic arm B (10) and the transverse telescopic arm (17) retract in sequence, so that the robotic arm B (10) is separated from the bearing. At this time, the conveyor belt (40) starts and carries the bearing to the Y-shaped distribution belt (41). The Y-shaped distribution belt (41) controls the rotating plate (42) under the action of the internal motor according to whether the bearing is recyclable or not, and adjusts the flow direction of the bearing on the surface of the Y-shaped distribution belt (41). Step S7: The Y-shaped material distribution belt (41) transports the bearing to the bearing splitting mechanism (43). During splitting, the telescopic rod B (47) controls the pad (48) and the movable plate (51) to descend. During the process, the clamping column (52) on the lower side of the movable plate (51) enters the inner side of the inner ring. The telescopic rod C (50) is activated, controlling the clamping column (52) to move closer to the baffle (49). Finally, the outer ring of the bearing is pressed against the baffle (49). The clamping column (52) and the baffle (49) clamp the bearing respectively. Inner and outer rings, at this time there is enough clearance at the end of the bearing away from the clamping point for the ball to slide down. After the telescopic rod B (47) controls the pad (48) to lift, the motor (45) controls the pad (48) to swing, and the ball falls onto the surface of the Y-shaped material distribution belt (41), which continues to transport it. After the ball is cleaned, the clamped ring is controlled by the motor (45) to swing to the outside of the Y-shaped material distribution belt (41), and then the clamping is released and it enters the storage box (53). Step S8: After falling, the balls on the surface of the Y-shaped separating belt (41) are buffered and guided by the buffer plate (55) and then enter the conveying line (54). The conveying line (54) passes through the concave holes (60) corresponding to the size of the balls and conveys the balls through the opening of the separation box (39) to the outside of the separation box (39). The separation conveying line (56) arranged on both sides of the conveying line (54) completes the surface defect detection of the balls through the vision camera B (57). The pusher plate (59) pushes the defective balls to the separation conveying line (56).
