A first optical lens 107 is installed on the first industrial camera 108. The first optical lens 107 is located directly above the first flexible disk 102. The output shaft on the right side of the first servo motor 106 and the connecting shaft on the right side of the first connecting plate 112 both pass through the L-shaped connecting seat 111 and are both fixed with a sprocket 113. The two groups of sprockets 113 are connected by a chain. Through the cooperation of the first vibrating motor and the first material bin 104, the pinhole parts can be vibrated onto the first flexible disk 102 in a sequential and regular manner. The first flexible disk 102 then vibrates to separate the parts to prevent the pinhole parts from overlapping, realizing the function of separating materials.

[0022] Working principle: Through the cooperation of the first vibration motor and the first hopper 104, the pinhole parts can be vibrated onto the first flexible disk 102 in a sequential pattern. The first flexible disk 102 then vibrates to separate the parts to prevent stacking, thus realizing the function of part feeding. Visual inspection is carried out by an industrial camera to prevent material mixing by judging features such as the diameter and length of each section. After taking pictures and positioning, the position signal is sent to the PLC controller, and the position coordinates of the visual feedback are obtained and sent to the first four-axis robot 109. The first jaw cylinder 105 clamps to grab the pinhole parts. After the grabbing is completed, the first servo motor 106 starts to drive the first jaw cylinder 105 to rotate 90° to make the pinhole parts vertical. Finally, the first four-axis robot 109 moves to the working area, and the first jaw cylinder 105 opens to transfer the pinhole parts into the dividing disk. The dividing disk rotates the fixture after discharging the parts to the next station. The second linear vibration motor 605 vibrates the O-rings into the second flexible disk 604. The second flexible disk 604 vibrates to separate the parts to prevent stacking of O-rings, thus realizing the function of part feeding. Then, visual inspection is carried out by an optical camera to prevent material mixing and stacking by judging features such as the shape / diameter. After taking pictures and positioning, the position signal is sent to the PLC controller. The PLC controller obtains the position coordinates of the visual feedback and sends a signal to the second four-axis robot 609. The second four-axis robot 609 moves to the material taking working area. The first slide cylinder 603 descends to make the elastic diameter-changing rod 602 penetrate into the O-ring. The first slide cylinder 603 retracts, and the material taking is completed. Then, the second four-axis robot 609 moves above the diameter changer 802. The first slide cylinder 603 descends and the elastic diameter-changing rod 602 retracts to place the O-ring in the diameter changer 802. The first slide cylinder 603 retracts, and the second station work is completed. It is transferred above the pinhole part material taking working area by starting the X-axis linear module 806. The first Z-axis module starts to descend to the working area. The second slide cylinder 812 works and descends. The pinhole part is sucked by the elastic diameter-changing rod vacuum suction pipe 814. The second slide cylinder 812 and the first Z-axis linear module 809 retract to complete the material taking. Then, the X-axis linear module 806 works and moves above the diameter changer 802. The first Z-axis linear module 809 descends. The second slide cylinder 812 starts to descend to push the O-ring that has completed the diameter change into the pinhole part groove to complete the assembly. The second slide cylinder 812 and the first Z-axis linear module 809 retract. The first X-axis module starts to move to the designated position. The first Z-axis linear module 809 and the second slide cylinder 812 start to place the assembled pinhole part in the fixture. Through the set insulating cap feeder 419, the insulating caps can be vibrated to the designated area in a sequential pattern. The first Y-axis linear module 414 starts to move above the insulating cap material taking working area. The second Z-axis linear module 416 starts to descend and presses down the insulating cap through the insulating cap fixing piece 418 to adsorb the insulating cap by vacuum negative pressure to achieve rapid material taking. After the material taking is completed, the second Z-axis linear module 416 rises. The first Y-axis module moves above the insulating cap assembly station and waits for assembly.The fourth servo motor 405 is activated to lower the swing cylinder 412 through the transmission belt 406. The third jaw 411 is activated to clamp and grab the pinhole part. The fourth servo motor 405 is activated to raise the swing cylinder 412 to the designated working area through the transmission belt 406. The swing cylinder 412 is activated to flip the pinhole part by 180°. The second jaw 404 and the third jaw 411 are activated to clamp the pinhole part simultaneously to prevent rotation. After the second Z-axis linear module 416 is activated to lower to the working area, the intelligent electric screwdriver 417 works to assemble the insulating nut and the pinhole part. After the assembly is completed, the second Z-axis linear module 416 rises, and the second jaw 404 releases. The swing cylinder 412 is activated to flip 180°. The fourth servo motor 405 drives the transmission belt 406 to lower and place the assembled part in the jig. The fourth servo motor 405 drives the transmission belt 406 to rise to the working area to complete the rapid assembly. The indexing plate assembly 2 is set to stop at the designated working area. The third industrial camera 303 takes pictures to determine whether the product is a good product or a defective product and sends a feedback signal to the PLC controller. The PLC controller sends a signal to activate the third Z-axis linear module 312 to lower, and the fourth jaw 307 clamps the product. After completion, the third Z-axis linear module 312 rises, and the second Y-axis linear module 304 is activated to move. When the signal sent by the PLC controller indicates that the product is a defective product, the second Y-axis linear module 304 stops above the defective product collection box 308. The third Z-axis linear module 312 lowers and the fourth jaw 307 releases, and the defective product falls into the defective product collection box 308. When the signal sent by the PLC controller indicates that the product is a good product, the second Y-axis linear module 304 is activated to move above the conveyor belt 302. The third Z-axis linear module 312 lowers and the fourth jaw 307 releases, and the good product falls onto the conveyor belt 302. The conveyor belt 302 transfers the good product to the good product collection box 301, achieving the effects of automatic detection and automatic sorting.
