AI Technical Summary

Technical Problem

Existing substrate mapping sensors struggle to accurately detect the overall shape and position of substrates within a containment container, particularly at the back of the container, due to illumination light reflection and difficulty in focusing on the dark areas away from the opening.

Method used

A substrate information acquisition device using a light emission unit and a light receiving unit configured as a vertically perpendicular planar shape, with a thickness thinner than the substrate pitch, to emit and receive light from the container interior, combined with a movement mechanism for relative movement, and an information acquisition unit to process the reflected light.

Benefits of technology

Enables accurate acquisition of substrate shape and position information within the container, including areas away from the opening, reducing the risk of substrate collisions during handling.

Abstract

The system accurately acquires information on the shape and position of multiple circuit boards in a front view within a containment container. [Solution] The light-emitting unit 61 of the substrate information acquisition device 60 emits illumination light 610, which is configured as a vertically perpendicular planar shape, into the interior of the storage container 7 through a container opening 71 provided on the front side surface of the storage container 7. The vertical thickness of the illumination light 610 is smaller than the vertical pitch P1 of the multiple substrates 9. The light-receiving unit 62 receives the reflected light reflected from the inner surface 73 of the storage container 7. The light-receiving unit 62 has the same optical axis as the illumination light 610 in the vertical direction. The moving mechanism moves the illumination light 610 and the light-receiving unit 62 relative to the storage container 7 in the vertical direction. The information acquisition unit acquires information on the shape and position of the multiple substrates 9 based on the output continuously output from the light-receiving unit 62 in parallel with the relative movement of the illumination light 610 and the light-receiving unit 62 by the moving mechanism.
