Description

Technical Field

[0001] This utility model relates to the field of optical inspection technology, and in particular to an optical inspection device for large-size products. Background Technology

[0002] In the production of large-size products such as large LCD panels, automotive parts, and mechanical molds, the differences in raw materials and molds result in some products failing to meet standards, leading to defective products. These defective products need to be manually selected, but there is no accurate standard for manual selection, making the distinction between qualified and unqualified products insufficient. At the same time, manual selection reduces inspection efficiency to some extent.

[0003] Currently, while there are some optical inspection devices for large-sized products on the market, most adopt a single-camera, multi-station layout. With multiple stations, the glass tray of the inspection equipment needs to be very large. Due to centrifugal force, the larger the tray, the more likely the product will move outwards, thus requiring a reduction in speed. However, this results in a production capacity almost identical to manual inspection, negating the purpose of automated inspection. Therefore, existing optical inspection equipment still needs improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses an optical inspection device for large-size products, including a glass disk and two sets of inspection mechanisms arranged along the circumference of the glass disk. The inspection mechanism includes a slide rail, a horizontal arm, a rectangular frame, multiple cameras, a strip light source, and a surface light source. The slide rail is arranged longitudinally on one side of the glass disk. The horizontal arm is slidably mounted on the slide rail via a first slide block. The rectangular frame is slidably mounted on the slide rail via a second slide block. The surface light source is slidably mounted on the slide rail via a third slide block. The horizontal arm, the rectangular frame, and the surface light source are all located on the same side of the slide rail.
