Problems solved by technology

At present, the line scan and UV glue detection are detected separately on different devices, because if the detection is performed on the same device, the camera for UV glue detection will be interfered by the side light source of the line scan, resulting in incorrect detection results

Abstract

The invention relates to the technical field of liquid crystal panel detection and discloses an LCD detection device, comprising a first detection device, wherein the first detection device comprisesa first machine table, a first conveying mechanism arranged on the first machine table, and an upper linear scanning mechanism, a PCB detection mechanism and a UV glue detection mechanism which are arranged on the first machine table and located above the first conveying mechanism, and a shading curtain is arranged between the upper linear scanning mechanism and the UV glue detection mechanism. According to the LCD detection equipment disclosed by the invention, the shading curtain is arranged between the upper linear scanning mechanism and the UV glue detection mechanism; and a side light source of the upper linear scanning mechanism can be prevented from interfering with a camera of the UV glue detection mechanism, so that linear scanning, PCB detection and UV glue detection can be carried out on the same equipment, the equipment cost is saved, and the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel detection, in particular to an LCD detection device. Background technique [0002] LCD (Liquid Crystal Display) liquid crystal display, its structure is to place a liquid crystal cell among two parallel glass substrates, set a TFT (thin film transistor) on the lower glass substrate, and set a color filter on the upper glass substrate. After the LCD is processed, it needs to be inspected for appearance. The appearance inspection of LCD includes line scanning, PCB board inspection and UV glue inspection. Line scanning includes online scanning and offline scanning. At present, line scanning and UV glue inspection are performed separately on different devices, because if the inspection is performed on the same device, the camera for UV glue inspection will be interfered by the side light source of the line scanning, resulting in incorrect detection results. [0003] In view of the above-...
