Overturning mechanism used for conducting picture inspection on liquid crystal panel

Abstract

The invention discloses an overturning mechanism used for conducting picture inspection on a liquid crystal panel. The overturning mechanism comprises a light box, a light box base fixedly arranged at the bottom of the light box and a support frame arranged under the light box base, wherein one side at the top of the support frame is fixedly connected with a support shaft through a bearing; the middle at the bottom of the light box base is fixedly connected with the support shaft through the bearing; a buffering device is fixedly arranged on the other side at the top of the support frame; a power device is fixedly arranged in the support frame; a connecting rod device is arranged and is connected with the power device and one side of the light box base; the light box is supported by the connecting rod device, the support shaft and the buffering device jointly; the power device can drive the connecting rod device, and drive the light box to rotate repeatedly by a set angle surrounding the support shaft to enable the light box to divorce from and contact with the buffering device. According to the invention, required capacity to fulfill overturning motion is relatively low; required time to fulfill the overturning motion is relatively short; the overturning angle required by the overturning mechanism can be realized; the work efficiency is improved.

Description

technical field [0001] The invention relates to a detection device used in the process of liquid crystal panel processing, in particular to a flipping mechanism for checking the picture of the liquid crystal panel. Background technique [0002] During the production and processing of LCD panels, inspectors are required to check the screens to ensure the quality of the ex-factory products. Since the orientation of the screens of the LCD panels inspected during production and processing is not consistent with the line of sight of the inspectors at the inspection position, therefore, when inspecting the screens of the LCD panels During the inspection, the inspector needs to flip the LCD panel at a certain angle by operating a flipping mechanism, so that the screen of the LCD panel faces the inspector, and then completes the inspection of the LCD panel screen, but the existing flipping mechanism completes the flipping action through a motor and a reducer , such a mechanism has t...
