Polishing machine for collecting lens

Abstract

A polishing machine for a collecting lens comprises conveying rollers located below the collecting lens and used for conveying the collecting lens, and a polishing disk brush located above the collecting lens and used for polishing the collecting lens. The polishing machine is characterized in that pressing rollers parallel to roller shafts of the conveying rollers are arranged above the middles of the conveying rollers; and the pressing rollers make contact with the upper surface of the collecting lens and cover the collecting lens in the width direction. According to the polishing machine for the collecting lens, the pressing rollers are arranged above the middles of the conveying rollers. The collecting lens is conveyed into the polishing machine through the conveying rollers and is polished under the action of the polishing disk brush. When the collecting lens begins to enter the polishing machine, the front end of the collecting lens is in the shape of an arc, and therefore the pressing rollers cannot affect the collecting lens; when the collecting lens totally enters the polishing machine, the middle of the collecting lens is pressed downwards by the pressing rollers, the arcs on the two sides can be pressed to be flat because the collecting lens is pressed, and therefore the two ends of the collecting lens can also make contact with the polishing disk brush to be polished; and the polishing effect is good, and the reflectivity of the finished collecting lens is improved.

Description

technical field [0001] The invention relates to the field of glass polishing, in particular to a polishing machine for condenser mirrors. Background technique [0002] In the mirror-making process of condenser mirror products, the role of polishing is to use cerium-based rare earth polishing powder to cut the fine concave-convex layer and crack layer on the glass surface through a disc brush, so that the glass surface is fresh and the surface is smoother. [0003] The quality of glass surface polishing will directly affect the reflectivity of condenser mirror products and the adhesion between metal reflective layer and glass. The better the glass surface is polished, the higher the reflectivity, which is the main index to measure the product quality of the condenser lens, will be after the metal coating process, and the stronger the metal reflective layer will be.

Problems solved by technology

[0004] The curved tempered glass polishing machine commonly used in existing condenser mirror production lines, when the glass with a large curved arc is transported into the polishing machine by the conveying roller and polished by the polishing disc brush, since the arc at the end of the glass is bent downward, the polishing disc brush It is often difficult to touch the end of the glass, resulting in unsatisfactory polishing effect of the end glass, which has a great impact on the reflectivity of the finished condenser mirror, resulting in serious restrictions on the use of curved tempered glass
