Optical lens polishing device

Abstract

The present invention relates to the technical field of polishing equipment, and specifically to an optical lens polishing device, comprising a base, wherein the top center of the base is rotatably connected to a rotating grinding table for polishing and grinding the lens, and a fixed bracket is installed on the right side of the top of the base. The present invention uses a vacuum pump to adopt negative pressure adsorption to perform integrated and synchronous adsorption and clamping of multiple optical lenses. While vacuum adsorption, the circumferential clamping assembly tightens the clamping block in the center by tightening the steel rope. The combination of the two improves the stable clamping of the optical lens, and the polishing liquid falls along the spiral channel. The gravity of the polishing liquid is used to achieve self-stirring and mixing. The rotation of the stirring blades in the mixing assembly is conducive to achieving uniform mixing and stirring of the polishing liquid. The integrated and synchronous linkage of the rotating polishing table, the linkage stirring mechanism, the reciprocating swing mechanism and the reciprocating feeding mechanism is synchronously driven by the driving motor, thereby reducing the number of driving parts.

Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to an optical lens polishing device. Background Art

[0002] Lenses are transparent materials made of optical materials such as glass or resin. Lenses are divided into different types according to their uses. Optical lenses are one of the more important ones. Optical lenses are divided into spherical lenses and flat lenses. Flat lenses are lenses with a flat surface. Flat lenses do not have the refractive properties of spherical lenses, but can reflect light. Therefore, flat lenses are widely used in digital cameras and laser equipment. Optical flat lenses need to be polished and polished by polishing equipment during the production process. Existing polishing equipment has certain defects when polishing optical lenses:

[0003] 1. When polishing a flat lens with existing polishing equipment, the flat lens is usually fixed to the grinding head by gluing or clamping with a clamp, and then the cam drives the grinding head to reciprocate, and then the polishing liquid is coated on the polishing disk. The polishing disk rotates continuously to cooperate with the reciprocating motion of the grinding head to achieve the grinding and polishing of the optical lens. The optical lens is fixed by gluing the lens with glue. After the polishing disk is polished, the adhesive glue needs to be removed, which easily causes the lens to be scratched. In addition, the clamping and fixing method is usually clamped by a threaded step-by-step fixing method. The clamping and loosening is time-consuming and inefficient.

[0004] 2. Existing polishing equipment needs to add polishing liquid when polishing optical lenses. The polishing liquid is made by mixing polishing powder and water. However, the density of polishing powder is greater than that of water. After the polishing liquid is left standing, the polishing powder will precipitate, causing the polishing powder and water to separate, reducing the polishing effect.

[0005] 3. When polishing optical lenses, existing polishing equipment usually performs fixed grinding and polishing on a single lens, and the grinding efficiency is low. During grinding, the grinding head drives the lens to reciprocate, and the polishing disk rotates automatically. The two cooperate to achieve the polishing of the optical lens. However, in the existing polishing equipment, the polishing disk and the grinding head are driven by separate driving sources respectively, which increases the number of driving sources and increases the use cost of the equipment.

The self-weight rotation of the polishing liquid by 412 and the spiral channel 413, the combination of the two realizes uniform mixing of the polishing liquid, and the rotation of the No. 1 rotating shaft 14 drives the reciprocating motion of the reciprocating swing mechanism 5, thereby realizing the reciprocating polishing and grinding of the optical lens. At the same time, the rotation of the No. 1 rotating shaft 14 also drives the reciprocating uniform feeding of the reciprocating feeding mechanism 8, thereby realizing the polishing and grinding of the optical lens. The integrated synchronous linkage of the rotating polishing table 2, the reciprocating swing mechanism 5, the linkage stirring mechanism 4 and the reciprocating feeding mechanism 8 is realized by using a single driving motor 13, thereby reducing the number of driving sources and reducing the cost of the equipment.
