Abstract

A cold light source exposure machine comprises a support, a slide holder, an exposure mechanism and a vertical adjusting mechanism; the slide holder is horizontally fixed at the lower end of the support; the vertical adjusting mechanism is used for adjusting the height of the exposure mechanism; the exposure mechanism comprises an ultraviolet light source, a polygonal mirror group, a reflector group, a mechanical shutter and a housing; the polygonal mirror group and the reflector group are both arranged in the housing; the polygonal mirror group comprises a plurality of reflectors which are annularly, uniformly and tightly arranged; the ultraviolet lamp source is arranged at the central point of the polygonal mirror group; the reflector group comprises a first reflector and a second reflector; the first reflector and the second reflector are oppositely arranged in parallel and form an included angle of 45 degrees with the horizontal direction; the first reflector is arranged right below the ultraviolet lamp source; the mechanical shutter is transversely arranged between the first reflector and the second reflector; and a collimating mirror is arranged under the second reflector. Accumulation of the thermal area on the slide holder of the exposure machine is avoided, the exposure efficiency is improved, the energy attenuation of ultraviolet light is greatly reduced, and the exposure area is enlarged.

Description

technical field [0001] The invention relates to the technical field of exposure machines, in particular to a cold light source exposure machine. Background technique [0002] Ordinary exposure machines use mercury lamp light source. Because the power of mercury lamp light source is too large, it is easy to cause heat accumulation and cause great loss to the exposure machine. In addition, it is inconvenient for ordinary exposure machines to adjust the distance between the light source and the convex mirror, which affects the exposure effect. To this end, CN209433181U discloses a single-sided cold light source exposure machine, comprising a bracket, a slide table, a convex mirror, a mechanical shutter and an LED ultraviolet light source, the slide table is horizontally fixed at the lower end of the support, and the LED ultraviolet light source is fixed on At the upper end of the support, the light of the LED ultraviolet light source sequentially passes through the mechanical s...
