Substrate detection device

Abstract

The invention discloses a substrate detection device. The substrate detection device comprises an illumination assembly, a bearing assembly used for bearing a substrate to be detected, and a platform where operation personal stay, and the illumination assembly and the bearing assembly are arranged on the two opposite sides of the platform respectively. By means of the substrate detection device, it can be avoided that an optical fiber shakes and touches a raster and the substrate to be detected, downtime and damage to the substrate to be detected are avoided, and the phenomena of light refraction, light reflection and turbulence caused by shaking of the optical fiber can be avoided to ensure the accuracy of a detection result and the cleanness of the detection environment; besides, when the brightness of a light source and the like need to be adjusted, operation personnel do not need to walk about, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a substrate detection device. Background technique [0002] The substrate inspection device is used to inspect the defects of the glass substrate, which is an important guarantee for the quality of the LCD panel. see figure 1 and figure 2 , the currently commonly used substrate inspection device 10 includes an illumination assembly 11 , a supporting assembly 12 for accommodating a substrate to be inspected, and a station 13 where an operator is located when inspecting a substrate 15 to be inspected. Wherein, the light source 111 of the lighting assembly 11 and the optical fiber 112 for powering the light source 111 are hung above the platform 13, that is, above the operator. This design is likely to cause some problems during detection, for example: 1. The optical fiber 112 is long, and it is easy to touch the grating 14 located on both sides of the detection window...

Problems solved by technology

Wherein, the light source 111 of the lighting assembly 11 and the optical fiber 112 for powering the light source 111 are hung above the platform 13, that is, above the operator. This design is likely to cause some problems during detection, for example: 1. The optical fiber 112 is long, and it is easy to touch the grating 14 located on both sides of the detection window due to shaking, resulting in the shutdown of the entire substrate detection device 10; It is also easy to touch the substrate 15 to be detected, causing damage or even breaking of the substrate 15 to be detected; 3. The shaking optical fiber 112 is prone to light refraction and reflection, which will interfere with the operator's line of sight and affect the accuracy of the detection results Four, the shaking of the optical fiber 112 will cause turbulent flow, which will affect the cleanliness of the detection environment; five, the components 113 for controlling the light source 111 of the lighting assembly 11, such as switch buttons, etc., are arranged on the upper left corner of the substrate detection device 10 , the distance from the platform 13 is relatively long, if the brightness of the light source 111 needs to be adjusted during the detection process, the operator needs to walk a long distance, which is time-consuming and inconvenient
