Description

Coating device

The present invention relates to a coating apparatus, and more particularly to a coating apparatus for an optical lens.

The lens module often produces stray light due to the reflection of light between the lenses, which causes ghosting and affects the imaging quality of the lens module. Therefore, how to eliminate the ghost image is a problem that must be considered in the process of manufacturing the lens module.

The existing method for eliminating ghosting is to apply a black matt lacquer to the non-effective optical aperture area of the lens, thereby reducing the inter-mirror reflection of the light, thereby eliminating the ghost phenomenon. At present, the application of the matt paint is artificial. Method of application.

However, since the lenses are often more precise, the requirements for applying the matt paint are relatively high, and the manual application may cause a coating failure with a slight inadvertentness. In addition, the manual application is time-consuming and labor-intensive, and the efficiency is low.

In view of the above, it is necessary to provide a coating device having high coating efficiency.

The load The surface of the plate is provided with a lens fixing area, and the lower end of the support arm is facing the lens fixing area. The operating platform defines a groove transverse to the surface thereof, and the opposite ends of the opposite side walls of the groove extend relative to a sliding rail. The carrier plate includes a sliding portion and a lens fixing portion on the sliding portion, and two opposite sliding grooves are formed on two sides of the sliding portion, and the sliding groove of the sliding portion and the sliding rail of the groove are mutually engaged In connection, the top edge of the sliding portion extends out of the flange for positioning the lens fixing portion. The lens fixing portion includes a bottom plate that is disposed at a top end of the sliding portion and located between the flanges, and a first side plate and a second side plate integrally formed with the bottom plate, one of which is disposed at a top end of the first side plate and parallel to the bottom plate a cover plate and a sliding baffle slidably disposed between the cover plate and the bottom plate. The first side plate and the second side plate are both parallel to the extending direction of the groove, and a plurality of first elastic members are disposed between the bottom plate and the cover plate.

The coating device is used to replace the conventional manual coating, and the coating is fast and uniform, thereby improving the coating efficiency.
