[0033] The working principle and method of using the device are as follows: starting and workpiece recognition stage, starting the equipment through the PLC controller 9, the electromagnetic vibrator 707 starts to work, drives the material taking frame 414 to vibrate, cooperates with the damper 705 and the damping spring 706 to buffer and dampen, makes the disorderly workpieces in the material taking frame 414 arranged in order, the first visual sensor 415 vertically captures the structural features of the workpieces in the material taking frame 414, automatically recognizes the guide column and the guide sleeve, and transmits the recognition signal to the PLC controller 9, and the PLC controller 9 matches the corresponding clamping and machining scheme; In the adaptive clamping and feeding stage, if the first vision sensor 415 identifies a guide pillar in the material taking frame 414, it transmits an identification signal to the PLC controller 9. The PLC controller 9 instructs the second servo motor 506 of the driving mechanism 5 to start. Through the synchronous belt 505 and the rotating wheel 504, the worm 502 is rotated. The worm 502 meshes with the worm gear 503 to drive the lead screw 403 to rotate synchronously. The lifting block 404 rises along the limiting groove 402 of the shell 401, so that the connecting frame 407 and the guide sleeve clamping pillar 409 are separated from the guide pillar clamping pillar 408. During the rising process, the fixed plate 410 supports and guides the connecting block 406 to prevent the connecting frame 407 from tilting. At the same time, after rising to the target position, the incomplete gear 413 meshes with the incomplete rack 412 to drive the rotating shaft 405 to flip (the angle sensor 416 monitors the angle and feeds back). When the connecting frame 407 is flipped to 90 degrees, the angle sensor 416 transmits a signal to the PLC controller 9. The PLC controller 9 drives the electric telescopic rod 420 to extend, so that the supporting plate 421 drives the limiting rod 422 to move. With the guiding action of the movable rod 423, the limiting rod 422 is accurately inserted into the limiting hole 418 of the fixed disc 417, realizing the locking of the connecting frame 407. If the first vision sensor 415 identifies a guide sleeve in the material taking frame 414 subsequently, it transmits an identification signal to the PLC controller 9. The PLC controller 9 first drives the electric telescopic rod 420 to retract, so that the limiting rod 422 is separated from the limiting hole 418 of the fixed disc 417, releasing the locking of the connecting frame 407. Then the PLC controller 9 instructs the second servo motor 506 of the driving mechanism 5 to start. Through the synchronous belt 505 and the rotating wheel 504, the worm 502 is rotated. The worm 502 meshes with the worm gear 503 to drive the lead screw 403 to rotate synchronously. The lifting block 404 descends along the limiting groove 402 of the shell 401. After descending to the target position, the incomplete gear 413 meshes with the incomplete rack 412 to drive the rotating shaft 405 to flip (the fixed plate 410 limits the flipping angle of the rotating shaft 405). When the connecting frame 407 is flipped to 90 degrees, it continues to move downward, so that the guide sleeve clamping pillar 409 is sleeved outside the guide pillar clamping pillar 408, automatically switching the use state of the guide pillar clamping pillar 408 and the guide sleeve clamping pillar 409. At the same time, the second vision sensor 703 positions the regular workpiece in the material taking frame 414. The first robot 701 grabs the workpiece through the electric clamping jaw 702 and moves it to the corresponding clamping pillar of the processing table 3 to complete the feeding; In the work station switching and parallel operation stage, after feeding is completed, the first servo motor 202 drives the processing table 3 to rotate. The universal wheel 204 slides along the slide 203, moving the work station with the workpiece to the polishing area. Another set of empty work stations moves to the feeding and discharging area. When the workpieces in the polishing area are being processed, the feeding and discharging area simultaneously feeds the next batch of workpieces and discharges the processed workpieces, realizing parallel operation. In the pressing and polishing stage, after the processing station is in place, the hydraulic cylinder 601 of the pressing mechanism 6 is started, driving the lifting plate 602 to stably descend along the support rod 605, the support frame 603 pushes the pressing plate 604 to press the workpiece, and then the second robot 801 of the polishing mechanism 8 drives the third servo motor 802 and the polishing head 803 to move, the third servo motor 802 adjusts the rotating speed of the polishing head 803, and the workpiece is accurately polished according to the preset trajectory; In the blanking collection and continuous processing stage, after the polishing is completed, the pressing plate 604 is raised and reset, the first servo motor 202 drives the processing table 3 to rotate, and the processed work station is moved to the blanking and feeding area, the first robot 701 grabs the processed workpiece and moves it to the collection frame 708 for storage, and the PLC controller 9 receives the workpiece remaining amount in the feeding frame 414 fed back by the first visual sensor 415 in real time, and issues a warning when the workpiece remaining amount is below the threshold, and the staff replenishes the raw materials, and the equipment continuously repeats the above process.
