Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0040] The invention provides a substrate detection device, such as figure 1 and figure 2 As shown, the substrate inspection device includes a backlight box assembly 1 through which a backlight is emitted, and the backlight is irradiated onto the substrate to be inspected, and inspectors detect defects on the substrate by observing the substrate.

[0041] Since the transparent acrylic on the back light box does not have the functions of filtering stray light, increasing sensitivity, etc., and cannot provide a clearer visual environment, too long observation time may easily cause discomfort or visual fatigue to the inspectors.

[0042] In order to solve the above problems, the substrate detection device provided by the present invention also includes a polarizer assembly 2, such as figure 1 and ...

Abstract

The invention belongs to the technical field of substrate detection and discloses a substrate detection device. The substrate detection device comprises a back light box assembly and a polarizing plate assembly, wherein the polarizing plate assembly comprises a fixed frame, a rotating mechanism and a polarizing plate; the fixed frame is located at a light source light-emitting side of the back light box assembly; the rotating mechanism is arranged on the fixed frame; the polarizing plate is connected with the rotating mechanism; and the rotating mechanism can drive the polarizing plate to rotate relative to the back light box assembly. According to the substrate detection device, a back light source is emitted through the back light box assembly and irradiates a to-be-detected substrate, so that an inspector detects a defect of the substrate through observing the substrate; the polarizing plate assembly is arranged at a light source generation side of the back light box assembly and the polarizing plate can filter out stray light and filter out 99% of glare, thereby providing a relatively clear visual environment and improving the visual comfort of the inspector; and the polarizing plate is rotated through the rotating mechanism, thereby changing the light-transmitting angle of the polarizing plate and facilitating overall observation of the inspector.

Description

technical field [0001] The invention relates to the technical field of substrate detection, in particular to a substrate detection device. Background technique [0002] In the production process of the liquid crystal display panel, in order to detect quality problems in the liquid crystal display panel early, the substrate of the liquid crystal display panel is inspected. For example, when performing macroscopic inspection on a substrate, the backlight is injected into the backlight from the back of the substrate, and the inspector can see the light illuminating the substrate, and then inspect the substrate. [0003] Since the existing detection device mainly uses the human eye to detect the defects of the substrate through the light, the transparent acrylic on the back light box does not have the functions of filtering stray light, increasing acuity, etc., and cannot provide a clearer visual environment. Discomfort or visual fatigue. [0004] Therefore, there is an urgent...
