In mobile phones, automobiles, medical, security, instruments and other industries, lenses are widely used. Lens gluing is a very important process in lens assembly production, a large number of lenses can not be inseparable from the use of [UVLED curing machine], it plays a vital role in the control of the internal light path of the lens, the quality of the glued lens will directly affect the optical performance of the lens.
The commonly used lens gluing method is optical gluing, which is quickly glued under the action of ultraviolet light. Two or more lenses are often glued together: Glue two convex lenses and concave lenses with opposite R-values and the same outer diameter material. First place the concave lens on the gluing fixture, and then superposition the adhesive surface of the convex lens with the adhesive surface of the concave lens. Before UV glue curing, the lens eccentricity is detected by optical detection instruments such as partial attachment/center attachment/fixing attachment. Then the strong UV irradiation of the [UVLED point light source] is used for pre-curing, and finally the UVLED curing box (UVLED surface light source can also be used), and the weak ultraviolet light is irradiated for a long time until the glue is completely cured, and the two lenses are firmly glued together.
Before, optical manufacturers in the lens and lens bonding, usually use mercury lamp UV furnace, and now most manufacturers in response to environmental protection and energy saving policies, began to use UVLED curing light source to improve yield and production efficiency. Compared with mercury lamps, UVLED light sources do not need to be preheated, ready to use, and can instantly achieve the required ultraviolet power output.
Curing box for the optical field: adhesive lens slow curing (curing), prism curing, etc. Semiconductor field: Developed for demanding curing applications such as wafer resist curing; Its light uniformity reaches more than 90%, the service life is up to 20,000 hours, low temperature energy saving, efficient curing. It can be used in optics, optical communication, semiconductor, microelectronics and other fields.
