Position precorrection device in ACF attaching equipment of flat-panel display

Abstract

The invention relates to a position precorrection device in ACF attaching equipment of a flat-panel display. The position precorrection device is characterized by comprising a camera mechanism (7), a precorrection table-board mechanism (8) and a transportation mechanism (9), wherein the camera mechanism (7) consists of a camera head (26) and an X-direction moving mechanism used for driving the camera head (26); the precorrection table-board mechanism (8) consists of an absorption table-board (44), a Z-axis rotating mechanism and a Y-direction moving mechanism; and the transportation mechanism(9) consists of an absorption arm (60) and an X-direction moving mechanism used for driving the absorption arm (60). According to the technical scheme, the position of two marking points of an LCD liquid crystal panel arranged on the precorrection table-board is captured by the camera head; if Y-direction deviation is found, the Y-direction deviation is corrected by using the Y-direction moving mechanism; if corner deviation is found, the corner deviation is corrected by using the Z-axis rotating mechanism; and if X-direction deviation is found, the X-direction deviation is corrected by usingthe X-direction moving mechanism in the transportation mechanism, so a driving terminal area of the LCD liquid crystal panel is positioned at a correct position, and the attaching accuracy of an ACF film is improved.

Description

technical field [0001] The invention relates to the field of flat panel display processing and manufacturing, in particular to a pre-calibration device used in ACF sticking equipment. Background technique [0002] In the manufacturing process of flat panel displays (FPD) such as LCD (liquid crystal) and PDP (plasma), it is an important task to correctly assemble drive circuits such as driver ICs or FPC (Flexible Printed Circuit) into the drive terminal area of ​​the display screen , the purpose of which is to drive the display screen to correctly display text and pattern information. ACF sticking is the process of sticking ACF film on the drive terminal area of ​​the display to mount drive circuits such as driver ICs or FPCs. ACF film (Anisotropic Conductive Film) is an anisotropic conductive film, which is a film with conductive particles scattered on an adhesive resin. The principle and process of LCD or PDP display substrate carrying driver IC or FPC through ACF film ar...

Problems solved by technology

The ACF application method of the above-mentioned Japanese patent cannot guarantee the accuracy requirements of ACF film application. Among them, the position error may directly lead to the appearance of defective products loaded with IC, and the ACF film application of excess length will not only cause waste of expensive ACF film, and cause a short circuit
