The rear second polishing station 28, the rear heating station 14, the rear unloading station 15 and the rear station are arranged in sequence from right to left along the second left-right transfer mechanism 41; the staggered surface assembly 5 includes a translation unit 51 and a rotation unit 52, and the rotation unit 52 is arranged on the translation unit 51.

[0027] By adopting the above technical solution, in the utility model, the clamp needle 61 on the clamp 6 first performs the powder sticking operation at the front powder sticking station 11, and then the crystal blank is loaded at the loading station 12, wherein the crystal blank needs to be heated when it is fixed on the clamp needle 61 during loading and when it is separated from the clamp needle 61 during unloading, wherein by providing the front cooling and glue transfer station 13, the crystal blank can be washed and cooled after being fixed on the clamp needle 61, so that the connection between the two is more firm. In addition, the front cooling and glue transfer station 13 is provided with a staggered surface assembly 5, because after the crystal needle is glued and loaded with powder, there will be excess adhered powder between the adjacent clamp needles 61, at this time, the clamp needle 61 is rotated by the staggered surface assembly 5, so that the excess powder on the clamp needle 61 can fall off, wherein the staggered surface assembly 5 can rotate the clamp needle 61 360 degrees or rotate back and forth by the same angle. Next, the crystal blank passes through the front rough grinding station 21, the front fine grinding station 22, the front first polishing station 23 and the front second polishing station 24, and then enters the docking station 32. The docking station 32, the front unloading station 33, the rear powder sticking station 34 and the docking waiting station 35 in the docking mechanism 3 of the utility model correspond to the docking machinery in CN104669088B or CN103273418B, wherein the docking position corresponds to the docking station 32 in the utility model, wherein the cleaning position corresponds to the front unloading station 33 in the utility model, wherein the docking powder sticking position corresponds to the rear powder sticking station 34 in the utility model, and wherein the waiting position corresponds to the docking waiting station 35 in the utility model. Next, the crystal blank enters the rear cooling transfer station to achieve better connection stability for the crystal blank to be subjected to grinding and polishing on the other side. In addition, a staggered surface assembly 5 is provided on the post-cooling transfer station. The staggered surface assembly 5 can be found in CN208100094U. The translation unit 51 in the staggered surface assembly 5 in the utility model is driven by a motor pulley mechanism, while CN208100094U is driven by a cylinder. The staggered surface assembly 5 needs to be retracted after the work is completed, so as to facilitate the transfer of the clamp 6 to the next station. The rotating body 521 of the staggered surface assembly 5 is connected with the worm on the clamp 6, so as to realize the rotation of the clamp needle 61. For details, please refer to CN105014532A. The specific structure of the clamp 6 can be found in CN110893584A. The crystal blank connected to the clamp needle 61 is rotated by the staggered surface assembly 5 at a certain angle, such as 25 degrees or 45 degrees, so that the upper and lower surfaces of the crystal blank are staggered to achieve a better aesthetics. The staggered surface action is performed before grinding and polishing, so that the waiting time of the clamp 6 entering the grinding and polishing operation is greatly reduced, thereby improving the production and processing efficiency. Next, the crystal blank is ground and polished on the other side and then enters the post-heating station 14, and then enters the post-unloading station 15 for unloading.After unloading, the fixture 6 enters the empty station 16, i.e., the waiting station, and then rotates horizontally to the front powder sticking station 11 (a rotating disk that can rotate in a horizontal plane will be provided between the empty station 16 and the front powder sticking station 11), thus entering the next cycle of production operation.
