Filming method and filming device

Abstract

The present invention provides a placement method and device. Through a scanning imager (11), the substrates placed on a substrate bearing plate (9) are filmed, and obtained image information is transmitted to a control computer (3). Through the control computer (3), the image information of the substrates (7) is subjected to software processing, the position of each substrate (7) and the direction of a corresponding terminal (71) are identified and confirmed, then a robot (5) is controlled to take, rotate and place substrates orderly according to the position of each substrate (7) and the direction of the corresponding terminal (71), the substrates (7) are placed on a substrate transfer mechanism (6) piece by piece, the terminal (71) of each substrate (7) faces a same preset direction on the substrate transfer mechanism (6), thus the substrates are placed according to a unified position and direction without operators, the placement speed is accelerated, the stop problem caused by the opposite placement of a substrate is avoided, and the working efficiency and the production capacity are improved.

Description

technical field [0001] The invention relates to the field of display device manufacturing process, in particular to a film casting method and a film casting device. Background technique [0002] In the field of display technology, flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) have gradually replaced CRT displays. [0003] The LCD display device is composed of a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate) and a color filter (Color Filter, CF) substrate, and liquid crystal is poured between the TFT substrate and the CF substrate. , through electrification or not to control the liquid crystal molecules to change direction, and refract the light from the backlight module to produce a picture. [0004] OLED has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing ...

AI Technical Summary

Problems solved by technology

If the substrate is placed upside down on the substrate carrier, e.g. figure 1 As shown, four substrates 200 are placed on the substrate carrier tray 100, and the three substrates 200 are arranged in the same direction, that is, the terminals 201 of the substrates 200 face the same direction, while the terminals 201 of the remaining one substrate 200 face the opposite direction, or the entire If the substrate carrier tray is placed upside down, the robot will take the film and put it back, and the data reader will fail to read the substrate code, resulting in downtime

[0007] Although there are documents posted on the job site for publicity, the situation of manual reverse substrates still occurs frequently, resulting in long downtime and affecting production capacity
