Device and method for simultaneously processing multiple planar optical parts

Abstract

The invention belongs to the technical field of optical part preparation, and particularly discloses a device and a method for simultaneously processing multiple planar optical parts.The device comprises a polishing machine, a base die and a bonding die, the base die and the bonding die are connected to the polishing machine, a fixing column is arranged on the edge of the base die, and a positioning area of the bonding die is determined on the base die; and the manufactured parts containing the adhesives are evenly distributed on the base die in the positioning area, the distance between the parts ranges from 1 mm to 2 mm, the bonding die is heated to 100 DEG C, hot pressing is conducted on the parts through positioning of fixing columns, and when the temperature of the bonding die is reduced to 70 DEG C, 100 g of pressure per square millimeter of the parts is applied till the parts are cooled and machined at the normal temperature. The device realizes simultaneous machining of multiple planar parts, higher surface precision and parallelism can be easily obtained, according to the size of the mirror disc of a polishing machine, compared with single optical part machining, the machining efficiency is improved by 5-30 times, and machining of ultra-small-diameter parts is simplified.

Description

technical field [0001] The invention belongs to the technical field of optical parts preparation, and in particular relates to a device and method for simultaneously processing multiple optical parts on a plane. Background technique [0002] Regardless of ordinary high-efficiency processing or traditional processing of flat optical parts, products with high requirements are generally processed in a single piece, or low-end products are required to be processed in multiple pieces, and the pass rate can usually reach 70-80%. Polishing machines require basic The number of pieces should cover more than 80% of the mirror disk, the size is uniform, and products with wedge-shaped parts cannot be processed. High-precision flat single-piece processing is not only inefficient, but labor costs continue to rise. The utilization rate of auxiliary materials is usually only 10% to 20%, and the requirements for processors are also very high. [0003] Therefore, we urgently need a multi-pie...
