Grinding device for small-diameter optical lens

Abstract

The invention belongs to the technical field of machinery, particularly relates to a grinding device for a small-diameter optical lens. The grinding device aims at solving the problem that in the prior art, a lens and a rubber layer are difficult to take down after being tightly extruded due to the structure of the grinding device for the optical lens for fixing the lens. According to the technical scheme, the grinding device comprises a fixing base with the upper end fixedly connected with an L-shaped fixing seat; a lens fixing mechanism comprises a first motor, a first electric push rod, a first clamping piece, a second clamping piece, a two-way suction cup and a second electric push rod; and the grinding assembly comprises a butterfly surface grinding rod. According to the grinding device for the small-diameter optical lens, the upper and lower edges of the optical lens can be formed through the arranged butterfly surface grinding rod, later reprocessing is avoided, and procedures are saved; through the arrangement of the two-way suction cup, the closed space formed between the rubber layer and the optical lens is freely opened and sealed, so that the suction force between the rubber layer and the optical lens is changed, and the optical lens is conveniently and stably placed and smoothly taken down.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a grinding device for small-diameter optical lenses. Background technique [0002] Optical glass is mixed with oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; The temperature is lowered slowly over time to avoid internal stress in the glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. [0003] Optical lenses are mostly used in optical equipment such as glasses, lenses, photographic camera lenses, etc., and achieve different viewing effects by refracting light. In...

Problems solved by technology

[0004] When the traditional lens edger grinds the corners of the lens, it clamps the two ends of the lens, uses the grinding wheel to grind slowly, and then performs chamfering, resulting in slow production efficiency, and because the lens material is relatively Brittle, it is easy to damage the corners of the lens when clamping the two ends, making it difficult to control the precision and quality of the lens. The matching concave and convex clamping blocks are set to clamp the upper and lower sides of the lens for grinding and chamfering, which makes the production efficiency high, and the rubber layer on the inner wall of the clamping block makes the clamping more stable. The lens will not shift during the grinding process, and the accuracy and quality of the lens will be improved

[0005] The above-mentioned device has the following disadvantages. First, it is inconvenient to form polished edges and corners. In addition, in order to improve the stability of the lens fixation, a rubber layer close to it is provided, but the rubber layer similar to a suction cup will make the lens and the rubber layer tight. Difficult to remove after squeezing
