Abstract

The coaxial ultraviolet projecting irradiation device treated with optical, photoelectron and microelectronic component glue and other methods comprises big power ultraviolet emitting source, projecting lens and beam synthetic lens with visible light entry, ultraviolet entry and synthetic light exit, the big power ultraviolet emitting source at the ultraviolet entry of the projecting lens, whose ultraviolet output corresponds with the ultraviolet entry of the synthetic lens, synthetic prism inside the synthetic lens, the said synthetic light exit corresponding with the lighted work piece surface, with simple structure, low cost, convenient in use, safe, elevated in optical energy utilization ratio, developing even lighting on the lighted surface, directly observing the treated surface, facilitating the work piece to fine tune and aligning.

Description

technical field [0001] The present invention relates to an ultraviolet projection illuminating device for coaxial observation for gluing and other processing of optical, optoelectronic and microelectronic devices. technical background [0002] In the existing technology, the technology of using ultraviolet light for surface treatment and photosensitive adhesive curing has a series of advantages such as high processing efficiency, accurate positioning, and no volatile solvents, and is widely used in scientific research, optical, optoelectronic, and microelectronic devices. development and production areas. In these working processes, when the two parts are glued and fixed together, after the ultraviolet photosensitive adhesive is coated on the glued surface, a microscope, a centering instrument and other instruments are used to observe and adjust the relative position of the glued parts so that zero After the relative position of the parts is consistent with the process requ...
