Embodiment approach
[0036] As an embodiment of the present invention, a small hole with a radius of 1.5 mm is opened in the middle of the sliding plate 51 , and the small hole enables the gas in the lower cavity of the sliding plate 51 to exchange with the gas in the box body 1 . When the cylinder 35 is compressed, the gas in the cylinder 35 enters the cavity on the lower side of the sliding plate 51, squeezes the sliding plate 51, and the gas is sprayed out of the piston unit 5 from the small hole, because the small hole inner diameter makes the small hole spray out The airflow pressure is high, and the gas ejected from the small hole can further fix the optical glass 9, avoiding the contact between the optical glass 9 that is about to enter the cooling module 4 and the sliding plate 51, deforming the surface of the optical glass 9, and changing the uniform distribution of the surface of the optical glass 9 characteristics.

The invention belongs to the technical field of optical glass processing, and particularly relates to an optical glass processing method, comprising the following steps: performing pretreatment on to-be-treated optical glass, putting the optical glass after pretreatment onto a conveyor belt in a heating furnace, fixing the optical glass by a heating module, an assisting unit and a piston unit, andbefore the optical glass prepares to enter a box, removing dust adhered on the surface of the optical glass by the match of the piston unit and the assisting unit, and performing thermal pretreatmenton the optical glass; driving the optical glass to move in the box by the match of the heating module and the piston unit, wherein the conveyor belt is driven to move together by the optical glass and static friction force on the conveyor belt, and the optical glass and the conveyor belt do not generate relative sliding, so as to avoid deformation of the optical glass and ensure the uniformity ofthe texture of the optical glass; processing the optical glass first in the heating module, and then annealing by a cooling module, so as to eliminate stress in the optical glass.
Description
technical field [0001] The invention belongs to the technical field of optical glass processing, and in particular relates to an optical glass processing method. Background technique [0002] With the rapid development of precision optical instruments, optical information communication, and optoelectronic products, the demand for optical glass with excellent performance is increasing, and the requirements are getting higher and higher. In optical design and optical communication, the refractive index is 1.9 The optical glass between ~2.2 has far-reaching significance for simplifying the optical system, improving the imaging quality, further miniaturizing mobile phones and digital cameras, and improving optical communication technology. Therefore, during the processing of optical glass, the surface material of optical glass is guaranteed It is particularly important that the stress and optical constants remain unchanged before and after optical glass processing.
