Exposure machine

An exposure machine, comprising:

• a loading frame, for placing an object to be exposed;
• a light source device, located at one side of a plane where the loading frame is positioned, wherein the light emitting direction of the light source device is perpendicular to a plane where the object to be exposed is positioned;
• and
• a supporting table which is horizontally disposed, the light source device is placed on the supporting table, and the loading frame is provided vertically on the supporting table;
• wherein the loading frame is of a hollow structure, such that after the object to be exposed is placed onto the frame, a surface of the object to be exposed is not in surface contact with the loading frame;
• wherein the loading frame and the light source device are configured and arranged so that during exposing, the loading frame does not reflect the light transmitting through the object to be exposed, thus avoiding stage spots forming on the object to be exposed;
• wherein the light source device comprises one light source and a prism located under the light source, wherein the light emitted vertically from the light source is reflected in the horizontal direction from two sides of the prism towards an exposure surface of the object to be exposed, and the reflected light is perpendicular to the exposure surface of the object to be exposed;
• and
• wherein two loading frames are provided at two sides of the light source device respectively, and the light reflected in the horizontal direction from two sides of the prism is capable of exposing the objects to be exposed in the two loading frames at the same time.
