Abstract

The invention discloses a light guide plate surface inspection jig device which comprises a conveyer belt, a light guide plate inlet rack, a light guide plate outlet rack and an inspection rack, wherein a light guide plate is inserted into the conveyer belt through the light guide plate inlet rack and is driven to the left side of the inspection rack; the inspection rack descends for inspection; subsequently the light guide plate is continuously driven to the light guide plate inlet rack for inspection along the conveyer belt. The light guide plate surface inspection jig device has the advantages that the structure is simple, the automation degree is high, and the light guide plate can be driven to an inspection station automatically, so that not only is the working intensity of operators alleviated, but also the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a fixture device for surface inspection of a light guide plate. Background technique [0002] Light guide plate surface inspection fixture device refers to the use of LED light strips as the light source of the fixture device, which emits light with high brightness through the LED light strip, penetrates into the light guide plate to form light conversion, and makes it bright to form a sharp color difference with the black backlight glass. Quickly check whether the product is abnormal. In actual production, the surface inspection of the light guide plate is carried out by artificial lighting. In this way, it is not only difficult to detect defective products, but also the inspection efficiency is low and the production cost is high. [0003] Aiming at the above technical problems, the invention with the authorized notification number CN204116242U discloses a surface insp...
