Description

Technical Field

[0001] The present invention relates to the technical field of optical device manufacturing, and in particular to a process and equipment for preparing an ultrathin optical filter. Background Art

[0002] With the development of communication systems, the market has seen demand for filters of various thicknesses. With the rapid growth of active products, the demand for filter thicknesses is also becoming increasingly thinner. Thicknesses of 0.3mm and 0.2mm no longer meet customer needs. Many customers have requested even thinner filters. However, stress is generated during the film formation process on the glass substrate, and the thicker the film, the greater the stress. This can cause the glass substrate to warp and deform during the coating process, altering film formation conditions and reducing the final yield.

[0003] Reference patent application number CN110963713A discloses an ultrathin optical filter and a method for manufacturing the same, comprising: fixing a glass to be coated to a substrate via an adhesive layer; coating the glass fixedly attached to the substrate; cutting the glass fixedly attached to the substrate; and debonding the coated and cut glass to be coated, thereby separating the glass from the substrate to obtain the ultrathin optical filter. However, debonding the glass to be coated can easily damage the coating on the glass substrate, affecting the quality of the finished filter. Furthermore, after debonding the glass to be coated, adhesive residue remains on the bottom surface of the glass substrate, requiring cleaning when subsequently coating the bottom surface of the glass substrate with an anti-reflection coating. This increases the number of filter preparation steps and reduces filter production efficiency. To address the aforementioned technical issues, the present invention provides a process for preparing an ultrathin optical filter and also discloses an apparatus for preparing the ultrathin optical filter.

[0022] (3) Beneficial effects

[0023] The present invention provides a process and equipment for preparing an ultrathin filter. Compared with the prior art, it has the following advantages:

[0024] (1) The glass substrate is ultrasonically cleaned by the cleaning mechanism to remove impurities on the surface of the glass substrate. The feeding mechanism adsorbs and feeds the glass substrate. In the processing mechanism, the glass substrate is first dried and then adsorbed and positioned. The top surface of the glass substrate is coated by the coating mechanism. Then, the bottom surface of the glass substrate is spin-coated. Finally, the glass substrate is fed into the collecting mechanism by the feeding mechanism to complete the automated production and preparation of the ultra-thin filter. There is no need to glue and position the bottom surface of the glass substrate, thereby avoiding debonding of the glass substrate, effectively protecting the coating on the glass substrate, and further improving the production and preparation efficiency of the ultra-thin filter.

[0025] (2) The glass substrate is ultrasonically cleaned in advance, then dried, and the top surface of the glass substrate is coated. The connecting frame is pushed downward by two servo electric cylinders until the bottom end of the sealing cover at the bottom end of the movable material tube contacts the bottom of the inner wall of the first groove. A sealed space is formed inside the sealing cover and the first groove. High-temperature coating material vapor is introduced into the movable material tube through the fixed material tube to form a coating layer on the upper surface of the glass substrate. During the coating process, the bottom surface of the glass substrate receives the adsorption force of the positioning suction cup, thereby avoiding stress on the glass substrate during the coating process, thereby effectively improving the production efficiency of the filter.

[0026] (3) By placing multiple glass substrates inside the feed frame and cooperating with the feeding mechanism to slide flexibly inside the chassis, the glass substrates can be flexibly transferred, and the cleaning, drying, coating and spin coating of the glass substrates can be completed inside the chassis. During the production and preparation of the filter, the glass substrates are not in contact with the outside world, which reduces the influence of external contamination on the glass substrates and further improves the quality of the finished filter.
