[0028] Each of the push components 763 includes an L-shaped seat 7631, and the L-shaped seat 7631 is provided with a second telescopic slide rod 7632 and a second telescopic spring 7633, and a downward pressure block 7634 is provided at the lower end of the second telescopic slide rod 7632. The right side of the downward pressure block 7634 is tilted to the left and has an inclined section 7635 for rolling with the first push wheel 7616.

[0029] The two switching ends 77 include a vertical column 771, and a second rotator 772 is provided on the upper end of the vertical column 771, and the front side of the second rotator 772 is connected to a swing rod 773 in a transmission manner. A connecting rod 774 is hinged on the right side of the swing rod 773, and the lower end of the connecting rod 774 is hinged to the upper end of the pressing slide rod 7514, and a second abutting wheel 775 for movably rolling against the top surface of the pressing annular plate 764 is provided on the left end of the swing rod 773.

[0030] Working principle: When grinding is required, the electromagnetic connection is first cancelled through the electromagnetic suction cup 74, and then the first rotator 71 drives the lower swing arm 72 and the annular seat group 73 to swing downward at an angle of 45-55°, so that the annular seat group 73 is disengaged from the horizontal sleeve at the lower end of the polisher 9, and then the rotating head 4 is switched to rotate 180°, and the grinder 8 and the polisher 9 are rotated and switched by switching the rotating arm 5, and then the first rotator 71 drives the lower swing arm 72 and the annular seat group 73 to swing upward and return to their original positions, so that the annular seat group 73 is horizontally sleeved with the grinder 8 again, and at this time, the top surface of the lower swing arm 72 is again against the electromagnetic suction cup 74 and electromagnetically connected, and the lower swing arm 72 is reinforced to prevent the first rotator 71 from being subjected to force.

[0031] In addition, the polishing auxiliary mechanism 75 and the grinding auxiliary mechanism 76 also need to be switched, and the second rotator 772 on the two switching ends 77 drives the swing rod 773 to swing to the left. At this time, the right end of the swing rod 773 is lifted up and pressed against the slide bar 7514 through the connecting rod 774, so that the bottom cover part 752 rises. In this process, through the spring rebound force on each first telescopic spring 7513, each first telescopic slide bar 7512 synchronously pulls multiple points on the top surface of the bottom cover part 752, so that the bottom cover part 752 can stably rise to above the outwardly extending oblique cutout 734, making way for each dust extraction group 762 to move horizontally in the direction of the outwardly extending oblique cutout 734, and When the left end of 773 swings downward, the second wheel 775 presses down on the left and right ends of the top surface of the annular plate 764, so that the second telescopic slide bar 7632 on each push assembly 763 drives the lower pressing block 7634 to descend on the L-shaped seat 7631. At this time, the second telescopic spring 7633 is in a tightened state. During the descending process of the lower pressing block 7634, the inclined section 7635 pushes the first wheel 7616 to the right, so that the slide seat 7612 drives the dust extraction group 762 to move horizontally to the right, and each tension spring 7613 will be in an outwardly pulled and tightened state. When each dust extraction group 762 simultaneously extends outward through the oblique cut 734, each dust extraction group 762 will be in a closed state. Fig.13 When the brush head group 7624 moves out of the outwardly extending oblique cutout 734, the brush head 76242 will automatically rotate vertically under the action of the reset spring 76243, and each brush head 76242 will automatically form a ring-shaped brush head, completing the automatic switching between the polishing auxiliary mechanism 75 and the grinding auxiliary mechanism 76.

[0032] The grinding method is that the robot body 1 drives the grinder 8 and the grinding and polishing auxiliary mechanism 7 to move horizontally. At this time, the grinder 8 is flat against the surface of the processed plate for rotational grinding, and the distance sensor 6 will use infrared light to pass through the middle channel of the annular seat group 73 to sense the distance in real time. When the grinding and polishing auxiliary mechanism 7 moves horizontally, each brush head 76242 forms an annular brush head that will softly contact the surface of the processed plate to clean the dust stuck on the surface of the processed plate, and the dust generated during grinding will gather in the middle channel cavity of the annular seat group 73, and the second vacuum cleaner is started to exhaust air simultaneously, and the downward inclined suction head 7622 on the dust extraction group 762 absorbs dust through each second suction pipe 7625, and the grinding, cleaning and dust collection are completed synchronously in the middle channel of the annular seat group 73 to prevent the dust generated during grinding from flying everywhere.

[0033] Polishing method, first through the above operation to automatically switch the sander 8 and the polisher 9, and the polishing auxiliary mechanism 75 and the grinding auxiliary mechanism 76 are matched and switched. It should be noted that when each dust extraction group 762 is retracted and expanded, the brush head 76242 will be laterally pushed outward into the bottom surface of the hollow structure around the annular base 731.

[0034] In addition, when the polisher 9 is grinding, the annular scraper plate 7533 will also be soft against the surface of the processed plate to automatically collect the scraping liquid during polishing. During polishing, the polishing agent mist spray group 754 is first assisted to start, and the polishing agent is pressurized by the pressurized liquid storage tank so that the polishing agent passes through the liquid inlet pipe 7544 and the annular jet pipe 7541 and is sprayed from each atomizing nozzle 7542 to spray the rotating polishing disk of the polisher 9 and the surface of the processed plate. When the polisher 9 is polishing horizontally, the annular scraper The liquid plate 7533 will also carry out corresponding scraping and polishing of the polishing agent, so that after the entire plate surface is polished, all the polishing agent can be concentrated on the inner circle periphery of the annular scraping plate 7533 and directly below the annular liquid suction nozzle 7531, and then the first vacuum cleaner is used to start the air suction, and the annular liquid suction nozzle 7531 extracts the polishing agent after polishing through each first air gathering hood 7532 and each first air suction pipe 7534, and the polishing, spraying of polishing agent, scraping of polishing agent, and extraction of polishing agent are completed in the middle channel of the annular seat group 73.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
