Description

Single-side film removing and secondary film coating equipment for double-side coated lens

Technical Field

The utility model relates to a processing technology of coated lenses, in particular to a single-side film removing and secondary coating device of double-side coated lenses.

Background

In the production process of optical vacuum coating, a certain amount of defective products can be generated, particularly the defective proportion of double-sided coating products is high, so that the film stripping and color fading process link is required to be involved in order to save the defective products. If the product is a high unit price product, the requirement on the film stripping process is higher.

At present, no special single-side film removing equipment exists for double-side film coated lenses.

In the conventional deplating method, the lens is simply soaked in a liquid tank with chemical reagents and subjected to ultrasonic and heating treatment to enable the optical film layer on the surface of the defective product to fall off from the product. Thus, the non-mold-release surface of the lens is damaged, and secondary defective products are easily caused again. After the film stripping and color stripping are finished, the non-film stripping surface needs to be coated again, so that great waste is caused in cost. Especially, the requirement of the double-sided coating of the lens on the fading process is more strict. Mainly because the optical film layers plated on the two surfaces of the lens are different in thickness, the chemical substances in the film stripping liquid are different in etching degree on the lens film layers in the same time, and defective products are easy to cause.

In view of this, the present inventors have specially designed a single-sided film removing and secondary coating apparatus to solve the above-mentioned problems during single-sided film removing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a single face of two-sided coating film lens moves back membrane and secondary coating film equipment, under the prerequisite that does not destroy the non-face of moving back, moves back the membrane with the one side that the lens has the coating film flaw and moves back the look, can greatly reduced secondary coating film's cost.

In order to achieve the above object, the solution of the present invention is:

a single-side film removing and secondary film coating device for double-side coated lenses comprises a damage-proof liquid soaking tank, a constant-temperature drying box, a film removing and color removing tank, a clear water tank, an ultrasonic cleaning machine and an optical film coating machine, wherein a lens basket is arranged on the damage-proof liquid soaking tank, the film removing and color removing tank, the clear water tank and the ultrasonic cleaning machine and used for bearing the double-side coated lenses to be treated, a conveying device is arranged among the damage-proof liquid soaking tank, the constant-temperature drying box, the film removing and color removing tank, the clear water tank, the ultrasonic cleaning machine and the optical film coating machine and used for conveying the double-side coated lenses to be treated, and the constant-temperature drying box, the ultrasonic cleaning machine and the optical film coating machine are connected with a control unit and work is controlled by the.
