Embodiment Construction

[0039] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] The invention provides a glass substrate correction device used on the roller transmission path, which is used for

[0041] Such as Figure 1 to Figure 3 As shown, a glass substrate position correction device of the present invention is shown, the glass substrate position correction device is used for correcting the position of the glass substrate being transported, especially for the correction of the glass substrate at the junction of the roller transport. It includes:

[0042] Roller sets 19 arranged on multiple rollers 13 can be used to transport glass substrates 11 through the rotation of said roller sets 19 in the same direction, wherein a plurality of rollers 13 are arranged at intervals, and the upper surface of said roller sets 19 Being on the same plane, the glass substrate 11 moves on the plane;

[0043] At least two guide shafts 14,...

Abstract

The embodiment of the invention discloses a glass substrate position correcting device which is used for correcting the position of a conveying glass substrate. The glass substrate position correcting device comprises a roller group, at least two guide shafts, at least two positioning devices, an air cylinder and a detecting device, wherein the detecting device detects the offset of the position of the glass substrate; the air cylinder drives the corresponding positioning device to move; and a part (extending out of the roller group) of the positioning device is abutted against the glass substrate, so that the glass substrate is adjusted to be at a correct position. The embodiment of the invention further discloses a glass substrate position correcting method. With the adoption of the glass substrate position correcting device and method provided by the embodiment of the invention, the glass substrate to be corrected can be automatically detected and correspondingly correcting can be performed.

Description

technical field [0001] The present invention relates to the field of liquid crystal panel manufacturing, in particular to a glass substrate position correction device and method. Background technique [0002] Due to the complexity of the thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) TFT-LCD manufacturing process, many processes require the use of glass substrate calibration devices. Especially between different types of machines, the position of the glass substrate may deviate due to the difference in process and handling methods, which needs to be corrected at any time. [0003] The misalignment of the glass substrate often occurs between the roller transmission and other transportation methods. If the misalignment occurs, the glass substrate may be damaged, resulting in a decrease in product yield. Therefore, it is necessary to set corresponding correction links in these places, and the existing position correction is o...
