Detection mechanism and detection method

Abstract

The invention relates to the technical field of glass substrate detection equipment, and discloses a detection mechanism and a detection method. The detection mechanism comprises an inner bearing frame which is configured to carry a part to be detected; an outer bearing frame which is arranged around the outer periphery of the inner bearing frame, wherein the inner bearing frame is rotatable relative to the outer bearing frame; and a position detecting component which is configured to detect whether the inner bearing frame and the outer bearing frame are in a coplanar position. The inner bearing frame is arranged to bear the part to be detected. The outer bearing frame is arranged around the outer periphery of the inner bearing frame, and the inner bearing frame can rotate relative to the outer bearing frame so that the angle between the part to be detected and the light emitted by the light source can be adjusted to obtain the better detection effect. The position detection component is arranged to detect whether the inner bearing frame and the outer bearing frame are in the coplanar position and load the part to be detected on the inner bearing frame to ensure safe loading of the part to be detected when the inner bearing frame and the outer bearing frame are in the coplanar position.

Description

technical field [0001] The invention relates to the technical field of glass substrate detection equipment, in particular to a detection mechanism and a detection method. Background technique [0002] Liquid crystal display has many advantages such as thin body, power saving and no radiation, and has been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through whether the glass substrates are energized or not, and refract the light from the backlight module to produce a picture. [0003] Before the liquid crystal display leaves the factory, it is necessary to carry out defect detection on the glass substrate. In the prior art, the detection mechanism f...

Problems solved by technology

However, when the servo motor or the machine fails, it will cause the inner bearing frame and the outer bearing frame to be in a non-coplanar situation. When the inner bearing frame and the outer bearing frame are in a non-coplanar situation, loading the glass substrate on the inner bearing frame will cause glass The damage of the substrate is more dangerous
