[0062] S5. After the four sides of the refrigerator door lining are cut and polished in sequence, the cut refrigerator door lining is sent out by an electric mechanical arm and an electric suction cup.

[0063] By adopting the above technical solution,

[0064] Working principle: After the refrigerator door lining is formed by a single vacuum forming machine, it is transported to the feed port through an external conveying device, and the electric mechanical arm 9 drives the electric suction cup assembly 10 to move to the top of the refrigerator door lining. The refrigerator door lining is adsorbed and fixed by the electric suction cup assembly 10, and then the driving end of the No. 2 motor 807 drives the drive shaft 801 to rotate counterclockwise for one circle through the pulley transmission group. The counterclockwise rotation of the drive shaft 801 drives the half gear 802 to engage with the No. 1 transmission gear 804 first. The half gear 802 has the same number of teeth as the No. 1 transmission gear 804, and the No. 1 transmission gear 804 is the same as the No. 2 transmission gear 806. When the half gear 802 is engaged with the No. 1 transmission gear 804, the drive shaft 801 rotates counterclockwise through the half gear 802. The first transmission gear 804 is driven to rotate clockwise for one circle, and the first transmission gear 804 drives the first rotating shaft 701 to rotate counterclockwise for one circle through the third bevel gear 706 and the fourth bevel gear 707. The first rotating shaft 701 drives the second rotating shaft 703 to rotate clockwise for a quarter of a circle through the driving wheel 702 and the driven wheel 704. The second rotating shaft 703 rotates through the circular seat 705 and the electric mechanical arm 9 to rotate a quarter of a circle, and then the refrigerator door lining is driven by the electric mechanical arm 9 to move to the corresponding cutting position, and the bottom of the refrigerator door lining is fitted with the workbench. When the electric mechanical arm 9 drives the refrigerator door lining to rotate, the refrigerator door lining is rectangular and the arc is too large during the rotation process. The grinding roller 504 will cause an obstruction to the refrigerator door lining during the rotation process;

[0065] Therefore, during the rotation process, the No. 1 driven shaft 803 drives the transmission shaft 605 to rotate synchronously for one circle through the synchronous wheel transmission group, and the transmission shaft 605 drives the No. 3 rotating shaft 602 to rotate synchronously for one circle through the No. 1 bevel gear 606 and the No. 2 bevel gear 607, and the No. 3 rotating shaft 602 drives the bottom plate 402 to move back and forth once through the No. 2 rotating rod 604 and the sliding frame 603, and drives the movable slide rail 401 to move through the bottom plate 402, and the movement of the movable slide rail 401 drives the refrigerator door lining deburring and grinding device 5 to move synchronously, and the refrigerator door lining deburring and grinding device 5 moves and rotates at the same time, and then resets, so that the refrigerator door lining deburring and grinding device 5 will not cause obstruction to the refrigerator door lining;

[0066] After the half gear 802 is separated from the No. 1 transmission gear 804, it continues to rotate counterclockwise. When the half gear 802 rotates to mesh with the No. 2 transmission gear 806, the driving shaft 801 drives the No. 2 driven shaft 805 to rotate one circle through the half gear 802 and the No. 2 transmission gear 806. The No. 2 driven shaft 805 drives the No. 1 rotating shaft 315 to rotate through the No. 5 bevel gear 808 and the No. 6 bevel gear 809. The No. 1 rotating shaft 315 drives the triangular rotating frame 312 to flip counterclockwise first and then reset through the No. 1 rotating rod 316 and the No. 3 connecting rod 317. When the triangular rotating frame 312 flips counterclockwise, the triangular rotating frame 312 drives the corresponding No. 1 sliding frame 302 and No. 2 sliding frame 303 to move closer to each other through the No. 1 connecting rod 313 and the No. 2 connecting rod 314. The No. 1 sliding frame 302 drives the cutting blade 306 to descend through the No. 1 connecting frame 304, and the No. 2 sliding frame 303 is The cutting plate 311 is driven to rise synchronously through the No. 2 connecting frame 310, and the refrigerator door lining is cut by the cutting blade 306 and the cutting plate 311. The No. 1 connecting frame 304 is driven to descend synchronously during the process of descending. The descending of the lifting plate 305 drives the protective fixing frame 308 to descend synchronously. The protective fixing frame 308 first contacts the refrigerator door lining, and the lifting plate 305 continues to descend to squeeze the spring 309. The spring 309 applies elastic force to the protective fixing frame 308, so that the protective fixing frame 308 is closely attached to the surface of the refrigerator door lining under the action of the elastic force of the spring 309. The protective fixing frame 308 has the effect of positioning the refrigerator door lining and performing secondary reinforcement while being adsorbed and fixed by the electric suction cup, so as to ensure the stability of cutting. The protective fixing frame 308 can protect the cutting blade 306; when the triangular rotating frame 312 is reset, it drives the cutting blade 306 to reset;

[0067] While the cutting blade 306 is cutting the refrigerator door lining, the second driven shaft 805 drives the second rotating shaft 405 to rotate. The second rotating shaft 405 drives the sliding plate 404 to move back and forth once under the guidance of the movable slide rail 401 through the rotating disc 406 and the swing rod 403. The reciprocating movement of the sliding plate 404 drives the refrigerator door lining deburring and grinding device 5 to move back and forth synchronously. When it is necessary to grind the refrigerator door lining, the electric cylinder 503 is turned on, and the driving end of the electric cylinder 503 extends to drive the grinding frame 502 to support The support slide rail 501 slides, so that the grinding roller 504 contacts the outer edge of the refrigerator door lining after cutting, and at the same time, the No. 1 motor 505 is controlled to be turned on. The driving end of the No. 1 motor 505 rotates to drive the two grinding rollers 504 to rotate synchronously. The grinding roller 504 rotates and reciprocates to grind and remove burrs on the cut edge of the refrigerator door lining. After the reciprocating cutting, grinding and deburring of the four sides of the refrigerator door lining are completed, the electric mechanical arm 9 and the electric suction cup assembly 10 are sent from the discharge port to the external conveying device for the lower process.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
