Description

Technical Field

[0001] The present invention relates to the field of waste bearing recycling, and in particular to a device and method for disassembling waste bearings. Background Art

[0002] Bearings are an important component in modern mechanical equipment and are mainly divided into two categories: sliding bearings and rolling bearings. Sliding bearings include three parts: rings, rolling elements and cages. The rings are divided into outer rings and inner rings. The rolling of the rolling elements between the inner and outer rings converts sliding friction into rolling friction. Its main function is to support the mechanical rotating body, reduce its friction coefficient during movement, and ensure its rotation accuracy.

[0003] The main reasons for the scrapping of discarded bearings include deformation, cracking and raceway wear. When disassembling, depending on the degree of damage, some parts with less damage can be put back on the market after repair, and parts with more serious damage can be recycled into industrial steel after crushing and melting, and continue to be used to manufacture new bearings or mechanical parts. During the bearing disassembly process, different parts have different materials and reuse values. It is necessary to first test their integrity and then carry out targeted recycling. For this reason, we propose a disassembly device and method for discarded bearings. Summary of the Invention

Several visual cameras B and telescopic rods D are fixedly installed on one side of the separation conveyor line. The movable end of the telescopic rod D is fixedly connected to a push plate, and the shape of the push plate is approximately L-shaped. The belt surface of the feed line is provided with concave holes, and the inner wall of the feed line is provided with auxiliary transmission belts and fixed belts at intervals on the lower side of the concave holes of the belt body. The auxiliary transmission belt and the fixed belt are used to control the ball to rotate downward in different directions in the concave holes.

[0014] The present invention also includes a method for disassembling discarded bearings, comprising the following steps:

[0015] Step S1: Place the bearing to be disassembled with the retainer screw side facing down on the conveyor line, and convey it to the lower side of the robot arm A by the conveyor line;

[0016] Step S2: Robotic arm A controls the movable end of 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 from the outside of the chuck A and presses against the bearing inner ring. The rotary arm rotates. At this time, robotic arm A can pass through the groove at the outer end of the box under the top plate and, controlled by the guide rail card, carry the bearing into the inner side of the box.

[0017] Step S3: After the robot arm A reaches the set position, the movable ends of the two telescopic rods A simultaneously approach the bearing cage, and finally the suction head at the front end of the telescopic rod A contacts the surface of the cage. The suction head sucks the cage through the connected pipes and the air compressor. At this time, the electric screwdriver starts 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 cages from both sides of the bearing. During the process, the cage close to the side of the robot arm A is cut off by the hydraulic clamp. After the cage is removed, the robot arm B controls its telescopic arm B to descend, and the front end of the horizontal telescopic arm is inserted into the gap on the upper side between the inner ring and the outer ring of the bearing. Then the horizontal telescopic arm extends outward to fix the upper distance between the inner ring and the outer ring;

[0018] Step S4: After the retainer is removed, the bearing is lifted by robot arm B, and the telescopic support block A on robot arm A retracts. After robot arm B controls the bearing displacement through the horizontal telescopic arm, robot arm A can be detached from the bearing and return to the conveyor line to wait for the arrival of the next bearing. The bearing carried by robot arm B then enters the ultrasonic cleaning box. The ultrasonic cleaning box is filled with a water-based detergent and added with <5% butyl cellosolve. The heating unit heats the solvent temperature to 60-70°C, the ultrasonic frequency is 40-80kHz, and the cleaning time is 10-15 minutes to clean the oil stains on the bearing surface. After cleaning, robot arm B carries the bearing to the drying area for drying;

[0019] Step S5: The dried bearing is carried to the raceway inspection unit by the robot arm B. The robot arm B controls the inner ring of the bearing to fit on the outside of the chuck B. Then, the telescopic support block C on the surface of the chuck B extends to fix the inner ring of the bearing. Then, the rotating wheel rotates under the action of the internal motor, so that the chuck B drives the inner ring of the bearing to rotate. During this process, the driven disk engages with the rotating wheel, so that the inner wheel drives the outer ring of the bearing to rotate as well. The light sources on both sides are respectively illuminated on the outer ring and inner ring raceways. When the outer ring and inner ring are rotating, the visual camera A detects surface defects of the raceway and the rings, and separates the recyclable rings from the non-recyclable rings.

[0020] Step S6: The bearing that has been inspected is carried by the robot arm B to the inclined conveyor belt. When the robot arm B lowers the bearing onto the conveyor belt, the transverse telescopic arm and the transverse telescopic arm at one end of the robot arm B retract in sequence, so that the robot arm B is out of contact with the bearing. At this time, the conveyor belt starts and carries the bearing to the Y-shaped material distribution belt. The Y-shaped material 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 material distribution belt;

[0021] Step S7: The Y-shaped material dividing belt conveys the bearing to the bearing splitting mechanism. During the splitting, the telescopic rod B controls the pad and the movable plate to descend. During the process, the clamping column on the lower side of the movable plate enters the inner side of the inner ring, and the telescopic rod C is started to control the clamping column to approach the baffle, and finally the outer ring of the bearing is pressed against the baffle. The clamping column cooperates with the baffle to clamp the inner and outer rings of the bearing respectively. At this time, there is enough gap in the bearing away from the clamping position at one end for the ball to slide down. After the telescopic rod B controls the pad to lift, the motor controls the pad to swing, and the ball falls to the surface of the Y-shaped material dividing belt. The Y-shaped material dividing belt continues to convey the clamped ring. After the ball is cleaned, the motor controls the pad to swing to the outside of the Y-shaped material dividing belt, releases the clamping, and puts it into the storage box.

[0022] Step S8: After falling, the balls on the surface of the Y-shaped dividing belt are buffered and guided by the buffer plate and then enter the conveyor line. The conveyor line passes through the recessed holes corresponding to the ball size on the surface and conveys the balls through the opening of the separation box to the outside of the separation box. The separation conveyor lines arranged on both sides of the conveyor line complete the surface defect detection of the balls through the visual camera B, and the pusher plate pushes the defective balls to the separation conveyor line.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this solution, a movable rotating wheel is provided. The rotating wheel rotates under the action of the internal motor, causing the chuck B to drive the inner ring of the bearing to rotate. During this process, the driven plate engages with the rotating wheel, causing the inner wheel to drive the outer ring of the bearing to rotate as well. The light sources on both sides illuminate the outer and inner ring raceways respectively. The visual camera A detects surface defects of the raceways and rings while the outer and inner rings are rotating, distinguishing between recyclable and non-recyclable rings.

[0025] The movable end of the telescopic rod D is fixedly connected to a push plate, which is approximately L-shaped, with the front end extending to the feed line. After detection, the corresponding ball can be pushed to the separation conveyor line. The surface of the belt body of the feed line is provided with concave holes, which are used for the belt body of the feed line to carry the ball to move. The size of the concave holes is not larger than the size of the ball. The inner wall of the feed line is provided with auxiliary transmission belts and fixed belts at intervals on the lower side of the concave holes of the belt body. The auxiliary transmission belt and the fixed belt are used to control the ball to rotate in different directions in the concave holes by contacting with the bottom of the ball when the ball passes by.

[0047] The present invention also includes a method for disassembling discarded bearings, comprising the following steps:

[0048] Step S1: Place the bearing to be disassembled with the retainer screw side facing down on conveyor line 1, and convey it to the lower side of robot arm A9 by conveyor line 1;

[0049] Step S2: Robotic arm A9 controls the movable end of telescopic arm A12 to extend downward until the clamping head A14 enters the inner side of the bearing inner ring. Then, the telescopic support block A15 extends from the outside of the clamping head A14 and presses against the bearing inner ring. The rotating arm 13 rotates.

After the retainer is removed, the robot arm B10 controls its telescopic arm B16 to descend, and the front end of the transverse telescopic arm 17 is inserted into the gap on the upper side between the inner ring and the outer ring of the bearing. Then the transverse telescopic arm 18 extends outward to fix the upper distance between the inner ring and the outer ring;

[0051] Step S4: After the retainer is removed, the bearing is lifted by the robot arm B10, and the telescopic support block A15 on the robot arm A9 retracts. After the robot arm B10 controls the bearing displacement through the transverse telescopic arm 17, the robot arm A9 can be detached from the bearing and return to the conveyor line 1 to wait for the arrival of the next bearing. The bearing carried by the robot arm B10 then enters the ultrasonic cleaning box 27. The ultrasonic cleaning box 27 is filled with a water-based detergent and added with <5% butyl cellosolve. The heating unit heats the solvent temperature to 60-70°C, the ultrasonic frequency is 40-80kHz, and the cleaning time is 10-15 minutes to clean the oil stains on the bearing surface. After cleaning, the robot arm B10 carries the bearing to the drying area 28 for drying;

[0052] Step S5: The dried bearing is carried to the raceway detection unit 3 by the robot arm B10, and the robot arm B10 controls the inner ring of the bearing to be sleeved on the outside of the chuck B32. Then the telescopic support block C33 on the surface of the chuck B32 extends to fix the inner ring of the bearing. Then the rotating wheel 31 rotates under the action of the internal motor, so that the chuck B32 drives the inner ring of the bearing to rotate. During the process, the driven disk 34 engages with the rotating wheel 31, so that the inner wheel 35 drives the outer ring of the bearing to start rotating. The light sources 38 on both sides are respectively illuminated at the outer ring and inner ring raceways. The visual camera A37 detects surface defects of the raceway and the rings while the outer and inner rings are rotating, and separates the recyclable rings from the non-recyclable rings.

[0053] Step S6: The bearing that has been inspected is carried by the robot arm B10 to the inclined conveyor belt 40. When the robot arm B10 lowers the bearing onto the conveyor belt 40, the transverse telescopic arm 18 and the transverse telescopic arm 17 at one end of the robot arm B10 retract in sequence, so that the robot arm B10 is out of contact with the bearing. At this time, the conveyor belt 40 starts and carries the bearing to the Y-shaped dividing belt 41. The Y-shaped dividing belt 41 controls the rotation of the movable 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 dividing belt 41;

[0054] Step S7: The Y-shaped material separation belt 41 transports the bearing to the bearing separation mechanism 43. During separation, 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, and the telescopic rod C50 is started to control the clamping column 52 to approach the baffle 49, and finally the outer ring of the bearing is against the baffle 49. The clamping column 52 cooperates with the baffle 49 to clamp the inner and outer rings of the bearing respectively. At this time, there is enough gap in the bearing away from the clamping position at one end for the ball to slide down. After the telescopic rod B47 controls the pad 48 to lift, the motor 45 controls the pad 48 to swing, and the ball falls to the surface of the Y-shaped material separation belt 41. The Y-shaped material separation belt 41 continues to transport the clamped ring. After the ball is cleaned, the motor 45 controls the pad 48 to swing to the outside of the Y-shaped material separation belt 41, releases the clamping, and puts it into the storage box 53;

[0055] Step S8: After falling, the balls on the surface of the Y-shaped dividing belt 41 are buffered and guided by the buffer plate 55 and enter the feed line 54. The feed line 54 passes through the recessed holes 60 corresponding to the ball size on the surface, and feeds the balls through the opening of the separation box 39 to the outside of the separation box 39. The separation conveyor lines 56 arranged on both sides of the feed line 54 complete the surface defect detection of the balls through the visual camera B57, and the push plate 59 pushes the defective balls to the separation conveyor line 56. In the embodiment, it should be added that the detected balls or rings can be further inspected later, and the detected bearings are not large bearings, and the detected balls are spherical balls.

At this time, the robot arm A (9) can be controlled by the guide rail card under the top plate (11) and pass through the outer end groove of the box body (19), carrying the bearing into the inner side of the box body (19); Step S3: After the robot arm A (9) arrives at the set position, the movable ends of the two telescopic rods A (20) simultaneously approach the bearing retainer, and finally the suction head (21) at the front end of the telescopic rod A (20) is against the surface of the retainer. The suction head (21) sucks the retainer 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 retainer with the cooperation of the rotating 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 retainers from both sides of the bearing. During the process, the retainer close to the side of the robot arm A (9) is cut off by the hydraulic clamp (26). After the retainer is removed, the robot arm B (10) controls its telescopic arm B (16) to descend, and the front end of the transverse telescopic arm (17) is inserted into the gap between the inner ring and the outer ring of the bearing. Then the transverse telescopic arm (18) extends outward to fix the upper distance between the inner ring and the outer ring. Step S4: After the retainer is taken out, the bearing is lifted by the robot arm B (10), and the telescopic support block A (15) on the robot arm A (9) is retracted. After the robot arm B (10) controls the displacement of the bearing through the transverse telescopic arm (17), the robot arm A (9) can be detached from the bearing and return to the conveyor line (1) to wait for the arrival of the next bearing. The bearing carried by the robot arm B (10) then enters the ultrasonic cleaning box (27). The ultrasonic cleaning box (27) is filled with a water-based detergent and added with <5% butyl cellosolve. The heating unit heats the solvent temperature to 60-70°C, the ultrasonic frequency is 40-80kHz, and the cleaning time is 10-15 minutes. The oil stains on the bearing surface are cleaned. After cleaning, the robot arm B (10) carries the bearing to the drying area (28) for drying. Step S5: The dried bearing is carried to the raceway detection unit (3) by the robot arm B (10), and the robot arm B (10) controls the inner ring of the bearing to be sleeved on the outside of the chuck B (32), and then the telescopic support block C (33) on the surface of the chuck B (32) extends to fix the inner ring of the bearing, and then the rotating wheel (31) rotates under the action of the internal motor, so that the chuck B (32) drives the inner ring of the bearing to rotate. During the process, the driven disk (34) is engaged with the rotating wheel (31), so that the inner wheel (35) drives the outer ring of the bearing to start rotating. The light sources (38) on both sides are respectively illuminated at the outer ring and inner ring raceways. The visual camera A (37) detects surface defects of the raceway and the rings in the rotating state of the outer ring and the inner ring, and separates the recyclable rings from the non-recyclable rings. Step S6: The bearing after inspection is carried by the robot arm B (10) to the inclined conveyor belt (40). When the robot arm B (10) lowers the bearing onto the conveyor belt (40), the transverse telescopic arm (18) and the transverse telescopic arm (17) at one end of the robot arm B (10) are retracted in sequence, so that the robot arm B (10) is out of contact with the bearing. At this time, the conveyor belt (40) is started and the bearing is brought to the Y-type dividing belt (41). The Y-type dividing belt (41) controls the rotation of the movable 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-type dividing belt (41); Step S7: The Y-shaped material separation belt (41) transports the bearing to the bearing separation mechanism (43). During separation, 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, and the telescopic rod C (50) is started to control the clamping column (52) to approach the baffle (49). Finally, the outer ring of the bearing is against the baffle (49), and the clamping column (52) cooperates with the baffle (49) to clamp the bearing respectively. Inner and outer rings, at this time, there is enough clearance in the bearing away from one end of the clamping position for the ball to slide down, and after the telescopic rod B (47) controls the pad (48) to lift up, the motor (45) controls the pad (48) to swing, and the ball falls to the surface of the Y-type material strip (41), and the Y-type material strip (41) continues to transport the clamped ring. After the ball is cleaned, the motor (45) controls the pad (48) to swing to the outside of the Y-type material strip (41), release the clamping, and put it into the storage box (53); Step S8: After falling, the balls on the surface of the Y-shaped dividing belt (41) are buffered and guided by the buffer plate (55) and enter the feeding line (54). The feeding line (54) passes through the recessed holes (60) corresponding to the ball size on the surface, and transports the balls through the opening of the separation box (39) to the outside of the separation box (39). The separation conveying lines (56) arranged on both sides of the feeding line (54) complete the surface defect detection of the balls through the visual camera B (57), and the push plate (59) pushes the defective balls to the separation conveying line (56).
