[0044] The working principle of the present utility model is as follows.

[0045] (1) Before working, the first electric cylinder 201 is started, and the movable frame 203 is driven to slide along the inner wall of the first sliding groove 202 by the first electric cylinder 201. When the movable frame 203 moves, the first moving rod 205 is driven to slide along the mounting plate 101 by the first moving rod 205. When the first moving rod 205 moves, the clamping plate 207 is driven to clamp the crystal 208 by the second moving rod 206.

[0046] (2) As the movable frame 203 moves, the fourth movable rod 304 is driven to move by the third movable rod 303, and the fourth movable rod 304 drives the track plate 306 to slide along the inner wall of the second sliding groove 307, thereby completing the docking of the two receiving grooves 305. When the two receiving grooves 305 are in contact, the inserting plate 314 extends into the two leaking plates 315, thereby closing the connecting channel between the receiving groove 305 and the lower groove 308.

[0047] (3) The third motor 504, the fourth motor 509, the second electric cylinder 501 and the third electric cylinder 507 are started at the same time. The second electric cylinder 501 drives the fourth motor 509 to move through the seventh moving rod 508. The fourth motor 509 drives the upper grinding shaft 510 to start, and the upper grinding shaft 510 is used to grind the upper side of the crystal 208. The third electric cylinder 507 drives the third motor 504 to move through the sixth moving rod 505, and the third motor 504 is used to grind the lower side of the crystal 208.

[0048] (4) The first motor 317 and the second motor 324 are started at the same time. When the first motor 317 is started, the first connecting rod 319 is driven to move through the first turntable 301. The first connecting rod 319 drives the first brush 321 to slide back and forth along the mounting plate 101 through the first driving plate 320, thereby sending the ground powder into the receiving groove 305. At the same time, the second motor 324 drives the second turntable 325 to rotate. The second turntable 325 drives the second driving plate 328 to move through the second motor 324. The second driving plate 328 drives the second brush 323 to slide back and forth along the mounting plate 101, thereby sending the ground powder into the receiving groove 305.

[0049] (5) After polishing is completed, the first electric cylinder 201 moves in the opposite direction to remove the polished crystal 208. At the same time, the receiving groove 305 moves in the opposite direction. At this time, the inserting plate 314 gradually separates from the leakage plate 315, and the fifth moving rod 310 drives the moving plate 311 to slide along the inner wall of the receiving groove 305, thereby allowing the powder in the receiving groove 305 to enter the leakage plate 315 through the square hole 313 and finally fall into the lower groove 308.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the appended claims, not the foregoing description, and is intended to encompass all variations within the meaning and range of equivalents of the claims, and any reference signs in the claims should not be construed as limiting the claims to which they relate.
