Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] 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.

[0017] 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 protected from vibrations generated 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] In general, the macro inspection equipment for LCD glass irradiates light on the glass substrate and enables workers to detect the amount of light reflected by the glass substrate, thereby using the difference in the amount of reflected light to determine whether the glass substrate is defective, that is, the glass substrate Whether there are normal parts, defective parts and / or recessed parts. Among these macro inspection equipment for LCD glass, i...
