Problems solved by technology

[0003] Under the existing conditions, the general factory requires the operator to place the glass on the operating table of a general-purpose desktop microscope to observe the film boundary, and then the operator manually sticks the film on the glass one by one. During the process, the operator’s eyes are prone to eye fatigue after observing the desktop microscope for a long time, and the distance between the film and the film is not easy to control when the film is applied, which makes the verticality of the film poor.

Embodiment 1

[0033] see figure 2 As shown, an optical glass laminating method applied to the above-mentioned optical glass laminating equipment, comprising:

[0034] Step S1: The staff wears silk gloves and holds the optical glass to inspect the surface of the optical glass. Before the optical glass is filmed, the surface of the optical glass to be filmed is inspected to find out the stains on the surface of the optical glass. The stain of the optical glass is judged by the method of water infiltration of the glass, cover the surface of the optical glass with clean water, the water adheres to the surface of the optical glass, and there are droplets or gaps on the formed water film, indicating that the surface of the optical glass has stains;

[0035] Step S2: Pretreatment of the optical glass, the staff wears silk gloves to hold the edge of the optical glass with stains on the surface, aligns the stained area with the air outlet of the air humidifier, and wipes the stained area with a sil...

Embodiment 2

[0044] The second embodiment deals with the case where the optical glass is partially pasted and the pasted film is attached on the basis of the pasted film,

[0045] The process of steps S1-S3 is the same as that of the first embodiment;

[0046] Step S4: the CCD alignment camera obtains the edge information of the film that has been pasted; specifically, the CCD alignment camera takes pictures and measures the four corners of the top surface of the optical glass, and determines the four corners of the top surface of the optical glass. Position information or take pictures of the boundary line between the optical glass and the pasted film, and determine the position of the boundary line by determining the position of the two intersection points between the boundary line and the edge of the optical glass;

[0047] The process of steps S5-S6 is the same as that of the first embodiment;

[0048] Step S7: Compare the edge information of the film that has been pasted on the optic...

Embodiment 3

[0051] The third embodiment deals with the case where multiple films are connected and pasted on the optical glass plate in turn. First, S1-S8 of the first embodiment is implemented, and then the process of S4-S8 of the second embodiment is repeated until the optical glass plate is pasted. Finally, the implementation is carried out. In S9 of Example 1 or Example 2, a cutter is used to cut off the film beyond the surface of the optical glass, and the optical glass is removed from the fixing table.

[0052] In the above three embodiments, in the process of steps S1-S9, the inner layer of the silk gloves worn by the staff is provided with a sweat-absorbing layer, or the inner layer of the staff wears rubber gloves and the outer layer wears silk gloves to prevent the staff from sweating. Affects the cleanliness of the gloves. During the implementation of step S5, a certain horizontal distance is maintained between the film and the optical glass, so as to avoid the impact on the ima...

Abstract

The invention provides an optical glass film coating method. The optical glass film coating method comprises the steps that a film coating position and the film position information on a piece of horizontally placed optical glass are measured through a CCD alignment camera, an angular distance difference between the film coating position and a film is determined, a fixing table is adjusted according to the difference to enable the film coating position on the optical glass to be aligned with the film, and then film coating is performed. In the process, staff only needs to fix the optical glassto the fixing table and fix the film to clamping arms, so that the process of observation and adjustment by the staff is eliminated, and eyes of the staff do not fatigue; and a machine performs filmcoating according to the precise position information to replace manual film coating, and the film coating accuracy is high.

Description

technical field [0001] The invention relates to the field of film sticking, in particular to a film sticking method for optical glass. Background technique [0002] Components made of optical glass are key elements in optical instruments. Optical glass can be used to manufacture lenses, prisms, mirrors and windows in optical instruments. In the process of optical glass production, it is often necessary to undergo film processing. [0003] Under the existing conditions, the optical glass film in the general factory requires the operator to put the glass on the operating table of a general desktop microscope, use the microscope to observe the film boundary, and then manually stick the film one by one on the glass. During the process, the operator's eyes are more likely to become tired after observing the desktop microscope for a long time, and the distance between the film and the film is not easy to control when the film is applied, which makes the verticality of the film p...
