Technical Field
The invention relates to the technical field of edge grinding machines, in particular to a half-rocker lens edge grinding machine.
Background
Ophthalmic lenses for spectacles can be made from many different materials such as glass, plastic, polycarbonate and thermoplastic resins. An ophthalmic lens undergoes a series of molding, surface finishing and polishing operations that determine the geometry of both the convex and concave optical surfaces of the lens. This surface modification may be followed by appropriate surface treatments such as multicoat, hard coat or tinting. The final step in the manufacture of ophthalmic lenses is edging, which comprises machining the edge or periphery of the lens to conform the size and shape of the lens to the size and shape of the frame in which it is to be mounted.
However, when the conventional lens edge grinding machine processes a lens, the lens needs to be fixed first; the clamping and fixing of the lens are difficult to control, and in the lens processing process, due to the impact action of cooling water and the counterforce of friction on the lens, the lens is easy to shift, so that the quality of the lens is affected; the suction cup of the existing lens edge grinding machine is too tightly fixed on the lens, the lens and the fixed suction cup are usually dismounted together when the lens is dismounted, and then the lens is separated from the suction cup; however, in a lens production line in a factory, the lens needs to be edged quickly, and the above-mentioned disassembly mode greatly affects the continuity of lens edging treatment, thereby greatly affecting the production efficiency of the lens.
In view of the above, the fixed disc is arranged at the end part of the fixed shaft, and the fixed disc is in close contact with the surface of the lens, so that air in the area between the fixed disc and the lens flows out through the first channel, and the lens is subjected to negative pressure and is tightly fixed; in addition, when the lens is taken down, air in the area between the fixed disc and the lens is supplemented through the air tank, so that the negative pressure effect on the lens is relieved, and the lens can be taken down smoothly and quickly.
