Embodiment Construction

[0040] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0041] In this disclosure, unless stated otherwise, the terms "up and down" refer to the orientation or positional relationship of the product in use, which can be understood as up and down along the direction of gravity. The "upper and lower" in the drawing correspond to each other; "inner and outer" refer to the "inner and outer" relative to the outline of the part or structure itself. In addition, it should be noted that terms such as "first" and "second" are used to distinguish one element from another, and do not have sequence or importance.

[0042] Embodiments of the present disclosure provide a glass substrate contrast detection device, referring to ...

Abstract

This disclosure relates to a glass substrate contrast ratio detection apparatus. The glass substrate contrast ratio detection apparatus comprises a vertical shaft (100), an installation frame (110) and a polarizing film (160). The installation frame (110) is disposed on the vertical shaft (100) in a front-back reversible manner. The polarizing film (160) is rotatably disposed inside the installation frame (110) around an axis of the installation frame. The glass substrate contrast ratio detection apparatus resolves a problem that an existing detection device is prone to causing glass substratedefect undetection, and helps to ensure quality stability of a glass substrate.

Description

technical field [0001] The present disclosure relates to the technical field of glass substrate detection, and in particular, to a glass substrate contrast detection device. Background technique [0002] In the quality inspection of glass substrates, it is sometimes necessary to inspect fixed glass substrates from different angles. [0003] However, the original inspection equipment can only inspect it from a plane angle, which will cause the omission of many defects that need to be detected from different angles, resulting in the instability of glass substrate quality inspection. Contents of the invention [0004] The purpose of the present disclosure is to provide a glass substrate contrast detection device, which solves the problem that the existing detection equipment easily leads to missed detection of glass substrate defects, and is beneficial to ensure the quality stability of the glass substrate. [0005] In order to achieve the above object, the present disclosur...
