[0022] The polishing mechanism 5 comprises a box body 51 with an opening downward, a polishing roller 53 driven by a motor II 52 is arranged longitudinally in the box body 51, the bottom end of the polishing roller 53 extends to the outside of the bottom of the box body 51, cleaning assemblies 54 are arranged in the box body 51 on both sides of the polishing roller 53, the cleaning assembly 54 comprises a circular pipe 541 arranged on the inner side wall of the box body 51, a lattice plate 542 is arranged in the circular pipe 541 to divide it into two groups of gas storage cavities 543, each gas storage cavity 543 is connected with a corresponding air extractor through a hose, a guide plate 544 is arranged on the bottom of one side wall of the circular pipe 541 and inclined downward toward the polishing roller 53, a plurality of nozzles 545 are uniformly arranged on the side wall of the circular pipe 541 below the guide plate 544 and communicated with the lower gas storage cavities 543, and a dust collector 546 is uniformly arranged on the side wall of the circular pipe 541 above the guide plate 544 and communicated with the upper gas storage cavities 543.

[0023] In this embodiment, an electric vacuum chuck 6 is arranged at the middle region of the top of the support plate 2, a recess 7 is further arranged at the middle of the top of the support plate 6, and an air bag 8 is arranged in the recess 7.

[0024] In this embodiment, the polishing roller 53 is provided with rotating shafts fixed on the side walls of the box body 51 through bearings at both ends, a pulley I for installing a transmission belt is arranged on one group of rotating shafts, the transmission belt passes through a through hole in the top wall of the box body 51, a motor II 53 corresponding to the transmission belt is arranged on the top of the box body 51, and a pulley II fixed with the transmission belt is arranged on the output shaft of the motor II 53.

[0025] The box 1 both sides wall on transverse set up sliding opening 9, the drive mechanism 4 includes the sliding seat 41 that sets up in the box body 51 both sides pass through the corresponding sliding opening 9, the sliding seat 41 outside the box body 51 is provided with the screw hole, the screw hole is screwed with the screw rod 52 that is parallel with the sliding opening 9, the screw rod 52 is driven by motor III 53, the box 1 outside is provided with the boss that fixes the screw rod 52 end by bearing.

[0026] When using, motor I 33 drives the screw rod I 32 to rotate in the screw pipe I 31, and the screw rod I 32 drives the gear disc II 35 by the gear disc I 34, to drive the screw rod II 36 to rotate in the screw pipe II 37, further drive the support plate 2 to move up to approach the opening at the top of the box 1, to facilitate the product to be placed on the support plate 2, wherein the product is fixed by the electric vacuum chuck 6, then the lifting mechanism 3 drives the product to move down and reset;

[0027] Further, motor III 43 drives the screw rod 42 to rotate in the screw hole of the sliding seat 41, to drive the sliding seat 41 to slide in the sliding opening 9 while driving the box body 51 to move left and right reciprocating, so that the bottom end face of the polishing roller 53 is displaced to the top end face of the product and contacts it, in the process, the support plate 2 and the product above it can be adjusted up and down by the lifting mechanism 3, further ensuring that the polishing roller 53 contacts the top end face of the product, while the motor II 52 drives the polishing roller 53 to rotate by the belt pulley, transmission belt and rotating shaft, and the top end face of the product is polished by the rotating polishing roller 53, at this time, since the drive mechanism 4 drives the polishing mechanism 53 to move horizontally, the polishing roller 53 can cover the entire top end face of the product, and when the box body 51 drives the polishing roller 53 and the cleaning assembly 54 to move on the top end face of the product, the top end face of the product to be processed can be swept and cleaned in one side of the cleaning assembly 54, to prevent the accumulation of impurities from affecting the polishing work, the specific steps are: the air blower introduces strong airflow into the air storage cavity 543 below and sprays it obliquely downward from the nozzles 545, and the flow guide plate 544 guides the airflow to blow the top end face of the product to be processed upstream of the polishing roller 53 to make the impurities rise, preventing the impurities from accumulating, at the same time, another set of air blower absorbs and cleans the dust and other impurities raised through the air storage cavity 543 above and the dust collector 546, and in the process, the flow guide plate 544 plays a guiding and blocking role, preventing the gas sprayed from the nozzles 545 from being sucked out by the dust collector 546 before it blows and cleans the top end face of the product, and the other side of the cleaning assembly 54 cleans the top end face of the product after polishing to prevent further accumulation of impurities to improve its quality, and the working principles of the two sets of cleaning assemblies 54 are the same, so they will not be described again.

[0028] When the processing is completed, the electric vacuum chuck 6 stops working. Since the product is adhered to the top surface of the support plate 2 and is not easy to be taken off, the air bag 8 is inflated to expand and slowly slide out of the groove 7, and then the product above the support plate 2 is slightly lifted to make one end of the product upwardly tilt, so as to facilitate people to take the edge of the product to take it off from the support plate 2.

[0029] The above has carried on the detailed explanation to the present application, but the content described is only the preferred embodiment of the present application, and cannot be considered to limit the implementation range of the present application. Any equivalent change and improvement made according to the application range of the present application should still belong to the patent coverage range of the present application.
