Problems solved by technology

[0004] However, as mentioned above, due to the large size and thin thickness of the glass substrate above the fifth generation, when the glass substrate is placed directly on the roller for positioning by a robot or manually, the glass substrate is often broken or damaged. missing corners, resulting in a decline in the pass rate, so how to overcome the shortcomings of the positioning machine in the prior art is an important issue in this field

Embodiment Construction

[0021] Please refer to FIG. 2 . FIG. 2 is a three-dimensional schematic view of the positioning machine of the present invention. The alignment machine 200 is an alignment machine for a glass substrate 204 such as a color filter (CF) substrate, a thin film transistor (TFT) substrate, or a plain glass substrate. Before the glass substrate 204 is to be processed in the next stage, the glass substrate 204 must be positioned first before being transported to an inspection machine (not shown) or a repair machine (not shown) by a robot or manually. As shown in FIG. 2 , the positioning machine 200 includes a roller 202 , a conveying track 208 , a lifting device 210 and a positioning device 206 . Wherein, each conveying track 208 is equipped with a plurality of rollers 202 at equal intervals, and the linear bearings 218 are used to drive each conveying track 208 to rotate, and the rollers 202 are rotated together, so that the rollers 202 can transport the glass substrate 204 to the po...

Abstract

The positioning worktable is in use for positioning glass base plate. The worktable includes multiple rollers located on multiple pieces of delivery track. Rollers are separated each other. Cardan and multiple pntels on the jacking up device support glass base plate to be left from rollers. Being located on two sides of positioning worktable, positioning units are in use for positioning glass base plates.

Description

technical field [0001] The invention relates to a glass substrate positioning machine, in particular to a glass substrate positioning machine with a lifting device of a universal bearing. Background technique [0002] The glass substrate is the key component of the liquid crystal display panel. In addition to the cost of the liquid crystal display panel, it has a more decisive impact on the pass rate of the liquid crystal display panel, and the glass substrate increases with the size of the liquid crystal display panel. increase. Taking the current fifth-generation liquid crystal display as an example, its glass substrate has reached a size of 1300 cm by 1500 cm, and the sixth generation has reached a size of 1500 cm by 1850 cm, but the thickness of the glass substrate has always remained at 0.6 cm. Between 1.1 centimeters and 1.1 centimeters, this makes the glass substrate prone to breakage or missing corners when using the prior art positioning machine for positioning, re...
