AI Technical Summary

Technical Problem

In the existing technology, when inspecting 3D curved glass, the curved glass is held and rotated by personnel under a fixed lighting environment, which leads to problems with the light source illumination strip, illumination angle, and personnel's viewing angle, resulting in the leakage of defective products.

Method used

Design a lighting device for 3D curved glass production inspection, including a bottom light fixture, a bottom light source, a bottom light outlet, a side LED light bar and a glass bracket. The rolling bearing and threaded rod mechanism realizes flexible adjustment of the light source and glass bracket. The adjustment of the frame ensures that the glass is evenly illuminated in different directions and facilitates the replacement and maintenance of the LED lamp body.

Benefits of technology

It reduces the risk of glass falling when holding the glass and the problem of uneven light reception, facilitates the detection of 3D curved glass of different sizes, and simplifies the replacement and maintenance of the side LED light source lamp body.

Abstract

The invention discloses an illumination device for 3D curved glass production inspection, which comprises a bottom light fixing seat. A cavity is formed in the bottom light fixing seat; a bottom lightsource is fixedly connected into the cavity; a bottom light illumination outlet is formed in the upper surface of the bottom light fixing seat; side surface LED light source lamp strips are arrangedon the left side and the right side of the bottom light illumination outlet; fixing mechanisms are arranged on the sides, opposite to each other, of the two side surface LED light source lamp strips;each fixing mechanism comprises an L-shaped supporting frame fixedly connected with the top of the bottom light fixing seat; a rolling bearing is embedded in the surface of the horizontal portion of each L-shaped supporting frame; a threaded rod is fixedly connected in each rolling bearing; and a threaded barrel is in threaded connection with the bottom of each threaded rod. The falling risk of glass held by personnel and the problem of uneven light receiving during glass rotation inspection by personnel can be reduced, the side surface LED light source lamp body can be conveniently replaced and maintained, and 3D curved glass with different sizes can be conveniently detected at the same time.
