When the workpiece body 15 is about to fall on the pallet 103, the lifting head 104 is stopped first, and then the two moving rings 601 are pushed away from each other by the first pushing assembly 8. At the same time, the first spring 703 is stretched. At this time, the upper moving ring 601 can push the upper rubber tube 13 to tilt upward, so as to clean the bottom of the workpiece body 15. At the same time, the lower moving ring 601 can push the lower rubber tube 13 to tilt downward, so as to clean the top of the pallet 103 and absorb the impurities after cleaning, thereby ensuring the efficiency and effect of automatic correction of the posture of the workpiece body 15.

[0037] The first reset mechanism 7 includes two symmetrically arranged first sleeves 701 fixedly connected to the ends of each movable ring 601, and each first sleeve 701 is inserted with a first rod 702, the lower end of the first rod 702 is fixed to the support frame 602, and the side wall of each first sleeve 701 is sleeved with a first spring 703, which guides and resets the movement of the movable ring 601.

[0038] The first pushing assembly 8 includes a third rotating shaft 801 rotatably connected to the inner wall of the annular cover 11, and one end of the third rotating shaft 801 is fixedly connected to a rotating disk 802, and the side wall of the rotating disk 802 is fixedly connected to two symmetrically arranged protrusions 803, and the rotation of the third rotating shaft 801 is driven by the second driving mechanism 9, and the third rotating shaft 801 is driven to rotate by the second driving mechanism 9, thereby pushing the rotating disk 802 to rotate, so that the two protrusions 803 are against the opposite ends of the two moving rings 601, thereby pushing the two moving rings 601 to move away from each other.

[0039] The second driving mechanism 9 includes a gear 901 fixedly mounted on the side wall of the third rotating shaft 801, and the side wall of the annular cover 11 is connected to a rack 902 through a moving mechanism 10, the rack 902 is meshed with the gear 901, and the rack 902 is moved by the moving mechanism 10, and the movement of the rack 902 drives the gear 901 to rotate.

[0040] The moving mechanism 10 includes a fixed plate 1001 fixedly connected to the inner wall of the annular cover 11, and two symmetrically arranged fixed rods 1002 are fixedly connected to the bottom of the fixed plate 1001, and the lower ends of the fixed rods 1002 are fixedly connected to blocks 1003, and the side walls of each fixed rod 1002 are sleeved with sliders 1004, the sliders 1004 are fixed to the side walls of the rack 902, and the side walls of each fixed rod 1002 are sleeved with second springs 1005, and the side walls of the rack 902 are fixedly connected with push rods 1006, and the lower ends of the push rods 1006 pass through the bottom of the annular cover 11, and the annular cover 11 continues to move downward through the lifting mechanism 16, and when the lower ends of the push rods 1006 abut against the top of the tray 103, when the annular cover 11 continues to move downward, it can push the rack 902 to move upward along the side walls of the fixed rods 1002, and at the same time, the second springs 1005 are compressed.

[0041] The lifting mechanism 16 includes a fixed block 1601 fixedly connected to the side wall of the lifting head 104, and a second set of rods 1602 are fixedly connected to the bottom of the fixed block 1601, and the side wall of the second set of rods 1602 is sleeved with a second sleeve 1603, and the lower end of the second sleeve 1603 is fixed to the top of the annular cover 11, and a threaded rod 1605 is rotatably connected to the bottom of the fixed block 1601, and a threaded tube 1604 is threadedly connected to the side wall of the threaded rod 1605, and the lower end of the threaded tube 1604 is fixed to the top of the annular cover 11, and a motor 1606 is fixedly connected to the top of the fixed block 1601, and the output end of the motor 1606 is fixed to the upper end of the threaded rod 1605, and the motor 1606 is started. The rotation of the motor 1606 drives the rotation of the threaded rod 1605, thereby driving the annular cover 11 to move up and down. When the annular cover 11 moves up and down, the rubber tube 13 is driven to move up and down synchronously through the rotating ring 12.

[0042] Working principle: When in use, the workpiece body 15 is placed on the tray 103 and transported along with the tray 103 on the track 102. When the tray 103 reaches directly below the lifting head 104, the transportation is stopped. Then, the motor 1606 is started. The rotation of the motor 1606 drives the rotation of the threaded rod 1605, thereby driving the annular cover 11 to move downward. When the annular cover 11 moves downward, the rubber tube 13 is driven to move synchronously through the rotating ring 12, so that the surface of the workpiece body 15 can be cleaned;

[0043] At the same time, the exhaust fan 204 is started to perform the exhaust operation. At this time, the air is exhausted through the through hole 14, so that the impurities after cleaning can be absorbed and enter the annular cover 11 through the rubber tube 13, and then enter the fixed box 202 through the exhaust pipe 201, and are filtered and collected after being discharged through the connecting pipe 203 and the exhaust fan 204. Moreover, when the air enters the fixed box 202, it impacts the surface of the blade 502 to rotate the power shaft 501. The rotation of the power shaft 501 drives the rotation of the second rotating shaft 402, thereby driving the first rotating shaft 301 and the rubber wheel 302 to rotate through the active pulley 403 and the belt 404, and then driving the rotating ring 12 and the rubber tube 13 to rotate, so that the cleaning efficiency is higher and the effect is better, and the subsequent centering clamping effect of the three-jaw chuck 105 is guaranteed.

[0044] After the cleaning is completed, the lifting head 104 is moved downward, and the top of the workpiece body 15 is clamped in the center by the three-jaw chuck 105. After the clamping is completed, the lifting head 104 drives the workpiece body 15 to move upward, and the three-jaw chuck 105 is rotated, so that the angle of the workpiece body 15 can be adjusted. At the same time, the industrial camera 106 is used for detection. After the adjustment is completed, the lifting head 104 drives the workpiece body 15 to move downward. When the workpiece body 15 is about to fall on the tray 103, the lifting head 104 is stopped first;

[0045] Next, the annular cover 11 continues to move downward through the lifting mechanism 16. When the lower end of the push rod 1006 abuts against the top of the tray 103, when the annular cover 11 continues to move downward, it can push the rack 902 to move upward along the side wall of the fixed rod 1002. At the same time, the second spring 1005 is compressed and pushes the gear 901 and the third rotating shaft 801 to rotate, thereby pushing the rotating disk 802 to rotate, so that the two protrusions 803 abut against the opposite ends of the two moving rings 601, thereby pushing the two moving rings 601 to move away from each other. At the same time, the first spring 703 is stretched. At this time, the upper moving ring 601 can push the upper rubber tube 13 to tilt upward, so that the bottom of the workpiece body 15 can be cleaned. At the same time, the lower moving ring 601 can push the lower rubber tube 13 to tilt downward, so that the top of the tray 103 can be cleaned and the impurities after cleaning can be absorbed, thereby ensuring the efficiency and effect of automatic posture correction of the workpiece body 15.
