Embodiment Construction

[0032] Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a conveyor belt used to transport substrates in the interlocking substrate rotation method of the present invention. As shown in FIG. 2 , a plurality of substrates 40 are carried on the conveyor belt 32 . Wherein, each substrate 40 may be a glass substrate, and each substrate 40 includes a substrate identification code (glass identification). A plurality of rotating stations 34 , 36 , 38 are also arranged on the conveyor belt 32 , and each of the rotating stations 34 , 36 , 38 is provided with a machine for performing photoresist coating or exposing and developing processes on the substrate 40 . For example, a photoresist coating machine can be installed next to the rotary station 34 , an alignment machine can be installed next to the rotary station 36 , and a developing machine can be installed next to the rotary station 38 . In addition, multiple pairs of sensors (sensors) 42 are disposed on the conveyor belt ...

Abstract

The invention relates to interlock type base plate rotating method. It includes the following steps: supplying one conveying belt set rotating station to transport many base plates; building one rotating direction parameter list and transporting to the base plate by conveying belt; when the base plate is transported to each rotating station, the rotating direction parameter list will automatically rotate it. The invention can use rotating parameter, base plate data, and sensor on the conveying belt to solve the problem that the product qualified rate is reduced by base plate rotating error for manhandling.

Description

technical field [0001] The invention relates to a substrate rotation method, in particular to a linked substrate rotation method. Background technique [0002] Thin film transistor liquid crystal display (hereinafter referred to as TFT-LCD) mainly uses thin film transistors arranged in a matrix, and cooperates with appropriate capacitors, transfer pads and other electronic components to drive liquid crystal pixels to produce rich and bright graphics. Because TFT-LCD has the characteristics of light and thin appearance, low power consumption and no radiation pollution, it is widely used in portable information products such as notebook computers (notebooks) and personal digital assistants (PDAs), and has even gradually replaced them. CRT monitors for traditional desktop computers and the trend for home TVs. [0003] Generally speaking, a TFT-LCD includes: a thin film transistor substrate, on which there are many thin film transistors arranged in an array, a pixel electrode (...
