[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Firstly, a charging device is used to fill a certain amount of gas into the interior of the No. 2 gas flow chamber 513 through the No. 2 gas channel 515. The gas needs to close the inner hole of the cylindrical air film 514, and the closing pressure is sufficient to make the lens be adsorbed on the open end of the hemispherical shell 54.
[0031] In order to achieve the gas adsorption fixing effect and driving effect of the lens, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , it is necessary to set up an adsorption drive mechanism 5, which is provided with a hemispherical shell 54 located in the grinding area 3 and capable of adsorbing and fixing the lens under a vacuum state, a main driving motor 53 capable of driving the hemispherical shell 54 to rotate, and a cylindrical air film 514 capable of controlling the gas pressure inside the hemispherical shell 54. When used in conjunction with an exhaust device, first, the lens is tightly attached to the fan-shaped sealing pad 58 and the open end of the hemispherical shell 54 in the direction of the grinding center area, and then the exhaust device is used to extract the gas in the No. 1 gas flow chamber 510. At this time, the gas pressure decreases, and the external atmospheric pressure will squeeze the lens between the fan-shaped sealing pad 58 and the open end of the hemispherical shell 54, forming a gas adsorption-type fixing effect on the lens. The suction process continues until the external gas flows from the inner hole of the cylindrical air film 514 to the No. 1 gas flow chamber 510, and the surface exhaust work can be completed. During grinding, the main drive motor 53 is turned on. At this time, the rotor of the main drive motor 53 will drive the hemispherical shell 54 to rotate, and finally drive the lens to rotate, thereby performing a rotational grinding effect on different corners of the lens.

At this time, the maximum depth of the lens being ground can be controlled, and the grinding wheel 615 is pressed downward, so that the grinding wheel 615 contacts the bottom of the polished area 3 of the lens, and then the auxiliary driving motor 614 is turned on.

The structural dimensions of the cross section of the cavity 63 match the structural dimensions of the cross section of the inner movable plate 66. A helical spring 68 in a compressed state is installed below the inner movable plate 66. The bottom end of the helical spring 68 abuts against the bottom port of the longitudinal component movable cavity 63, and the top end abuts against the lower surface of the inner movable plate 66.

[0035] To adjust the lateral position of the lens, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8, it is necessary to set up a horizontal adjustment mechanism 7, which is internally provided with a horizontal threaded rod 73 located in the top area of the grinding area 3 and capable of rotating, a movable docking block 75 installed on the periphery of the horizontal threaded rod 73 through a secondary threaded structure and capable of lateral displacement when the horizontal threaded rod 73 rotates, and a horizontal limit rod 72 capable of preventing the movable docking block 75 from rotating. By turning the hand wheel 74, due to the existence of the secondary threaded structure, the movable docking block 75 will drive the lens to lateral displacement, and the lens will be moved to just above the grinding wheel 615, thereby realizing the lateral position adjustment function of the lens.
