Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an edge grinding machine. Background Art

[0002] High-transmittance hard-coated lenses combine high light transmittance with exceptional hardness. These lenses are typically coated using a specialized coating process to create one or more layers of hard coating on the lens surface. This enhances the lens's wear resistance and lifespan while maintaining or enhancing its light transmission. High-transmittance hard-coated lenses utilize advanced coating technology to effectively reduce reflected light from the lens surface and increase light transmittance, resulting in clearer and brighter vision. By applying one or more layers of hard coating to the lens surface, the lens's resistance to wear and tear is significantly improved, minimizing scratches and damage caused by daily friction and cleaning, thereby extending its lifespan.

[0003] During the processing of high-transmittance hard-coated lenses, they require edging. This process can make the edges of the lenses smoother and flatter, improving the appearance quality of the lenses and removing burrs and sharp corners. Existing edging processes often rely on manual lens clamping and loading, resulting in low processing efficiency and the inability to adjust the grinding process to different angles.

The circular lens with protective paper is placed vertically inside the storage box 13, and is pressed to one end of the material taking slot 19 by the pushing part. When taking the material, the cylinder group drives the No. 2 vacuum suction cup 18 to move horizontally so that the No. 2 vacuum suction cup 18 passes through the material taking slot 19 and contacts the lens and then adsorbs it. Then the cylinder group lifts the lens through the No. 2 vacuum suction cup 18 and resets it horizontally and then moves downward so that the center of the lens contacts the No. 1 vacuum suction cup 11 below. The inner wall of the equipment cover 2 is provided with an infrared sensor, which detects When the bottom of the lens reaches the specified position, the No. 1 vacuum suction cup 11 adsorbs the lens, and the No. 2 vacuum suction cup 18 resets upward.
