Abstract

The invention discloses a fracturing process for laser optical glass cutting. The process comprises the following steps: (1) an optical glass plate is placed in a laser cutting machine for cutting; (2) the optical glass plate is positioned in a fixture lifting basket after laser cutting; (3) the fixture lifting basket with the optical glass plate is totally merged in wetting permeation liquid by 10-30 seconds; (4) the merged fixture lifting basket with the optical glass plate is slowly pulled out from the wetting permeation liquid; and clean air currents are used for blow drying of the wettingpermeation liquid on the optical glass plate and the fixture lifting basket; (5) the dried optical glass plate is put in a plastic packing box; (6) the plastic packing box with the optical glass plate is transferred into a microwave working station for microwave processing; and (7) a finished glass plate and edge frame wastes in the plastic packing box are taken out. The process realizes automatic large-batch fracturing of wafers, improves the fracturing efficiency, reduces the use cost, guarantees the cleanness after fracturing, and reduces the cost of similar process laser fracturing equipment.

Description

technical field

[0001] The application technical field of laser cutting of optical glass of the present invention is specifically a splitting process of laser optical glass cutting. Background technique

[0002] In the current microelectronics industry, optical applications are becoming more and more extensive. The precision and efficiency of optical glass manufacturing and processing are constantly improving. Generally, the optical glass manufacturing process in the microelectronics industry is as follows: 1. Coating optical films with specific optical properties on the substrate through a coating machine, such as anti-reflection film, anti-reflection film, infrared filter film, etc. 2. Process the coated glass into the shape, specification and size required for assembly. Now optical glass forming processing mainly includes CNC machine tool processing, laser cutting processing, mechanical wire cutting or blade cutting process. For small size, circular or square optical f...
