Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 2a with 2b , The macro inspection apparatus for LCD glass according to the present invention includes an LCD glass holder 10, a pair of parallel hinged connection units 20 and 20' for supporting the side surface of the glass holder 10, a rotating connection unit 20 and A 20' rotating unit 30, a traveling axis for guiding the left and right linear movement of the macroscopic inspection equipment, and a controller for controlling the position of the LCD glass holder.

[0018] As LCD glass becomes larger, the macro inspection equipment becomes larger. Therefore, both sides of the LCD glass holder of the large-scale macro inspection device are supported to form a stable structure of the inspection device. Such as Figure 2a with 2b As shown, a pair of connecting units 20 and 20' having a parallel hinged connection structure...

Abstract

The invention discloses macroscopic inspection equipment for LCD (Liquid Crystal Display) glass. Both sides of a glass retainer are supported by utilizing a pair of parallel hinging type connecting units so as to protect the LCD glass from vibration generated by driving macroscopic inspection equipment; and by adopting the parallel hinging type connecting units, the X-axis motion, Z-axis motion and inclination of the glass retainer are realized by a single electrode. The macroscopic inspection equipment comprises the LCD glass retainer, a pair of parallel hinging type connecting units, a rotating unit, an advancing shaft and a controller, wherein the pair of parallel hinging type connecting units are used for supporting the side surface of the glass retainer; the rotating unit is used forrotating a pair of connecting units; the advancing shaft is used for guiding the left and right linear motion of the inspection equipment; and the controller is used for controlling the position of the LCD glass retainer.

Description

Background technique [0001] The present invention relates to a macro inspection device for LCD glass, and more specifically, to a macro inspection device for LCD glass, in which a pair of parallel hinged connection units are used to support both sides of a glass holder to protect The LCD glass is free from vibration caused by driving the macro inspection equipment, and drives two connection units with a single motor to easily control the pair of connection units without synchronizing the motors. Background technique [0002] The Japanese patent application published on April 20, 2006 with the publication number JP2006105747A provides a plate-shaped body inspection device that can be used to inspect glass used for liquid crystal display substrates. The inspection equipment includes a glass support part, a control device for controlling the glass support part, a connecting part, a driving motor for driving the connecting part, a rotation driving device and a traveling shaft that gu...
