Description

Fully automatic pre-pressing machine for pressing COF and LCD

Technical field

The invention relates to the technical field of automatic manufacturing of liquid crystal panels, in particular to a fully automatic pre-pressing machine for pressing COF and LCD.

Background technique

The liquid crystal panel, also called LCD (Liquid Crystal Display), is a flat and ultra-thin display device. It consists of a certain number of color or black and white pixels placed in front of the light source or reflective surface.

The display principle of the LCD is to fill the liquid crystal material between the two parallel plates, and to change the arrangement of the molecules inside the liquid crystal material by the voltage, so as to achieve the purpose of shading and light transmission to display images of different shades and irregularities. Moreover, by adding a ternary color filter layer between the two plates, a color image can be displayed. At present, monochrome LCDs have almost withdrawn from the notebook market, and color LCDs continue to develop. Color LCD is mainly divided into STN and TFT. Among them, TFT (Thin Film Transistor) LCD, also known as active electro-crystalline thin film transistor liquid crystal display, is a true color LCD screen commonly known by many people; DSTN (Dual -Scn Twisted Nematic) LCD, a dual-scan LCD display, is a display method for STN LCDs and has now withdrawn from the market.

The electrical signal component of the liquid crystal display is mainly composed of a backlight circuit and a display circuit, wherein the display circuit is used for transmitting the electric charge and control signals required for the pixel driving of the liquid crystal panel, and is mainly transmitted by using a printed circuit board (PCB) (Printed Circuit Board). At the same time, the driver IC (Driver IC) is required to transfer the charge and control signals to the liquid crystal panel. Generally speaking, one end of the Driver IC is connected to the LCD panel, and the other end is connected to the PCB. Generally, the adjacent sides of the liquid crystal panel are divided into a Gate end and a Source end, and the Driver IC of the Gate end is connected to the Gate end of the liquid crystal panel, which is responsible for switching the switches of each column, and opens an entire column of transistors at the time of scanning, and the Driver IC of the Source end is connected. To the Gate end of the LCD panel, when the transistor is turned on, the Driver IC at the Source can progressively control the brightness, gray scale, and color control voltage through the channel formed by the Source and Drain terminals of the transistor into the pixels of the LCD panel. Therefore, in the process of manufacturing the liquid crystal display, the liquid crystal panel, the Driver IC, and the PCB need to be sequentially pressed together.

At present, the interconnection of the liquid crystal display driver chip Driver IC and the liquid crystal panel LCD mainly adopts a chip-on-flex (COF) package technology. Referring to FIG. 1 , the flip chip COF packaging technology refers to directly mounting a bare chip for driving a liquid crystal cell on a disturbing substrate, and then connecting the disturbing substrate to the LCD and the PCB respectively. In this interconnection technology, the driving chip IC is driven. The electrical signal reaches the controlled pixel point via the bonding point of the chip to the substrate and the metal line on the substrate. Therefore, it is necessary to press and connect the COF with the liquid crystal display LCD and the printed circuit board PCB. Through this step, we can achieve two purposes. One is that the COF can be electrically connected to the PCB and the LCD through the conductive particles, thereby allowing The current signal flows, and the second is that the machine presses to provide a certain temperature and pressure. By controlling the pressing time, the two different materials are connected together at a high temperature to provide sufficient working strength to prevent mutual falling off and affect the service life.

In the existing COF and LCD preloading steps, the following problems often exist:

1. For the adjustment of the positional state of the liquid crystal display LCD, manual adjustment is usually adopted, and more steps are required for manual assistance, which not only improves the adjustment time, but also the positional accuracy is difficult to ensure;

2. The existing LCD placement platform has fixed requirements for the size of the LCD that needs to be placed and positioned, and has poor adaptability. It cannot be adapted to other similar products of the same size. For the frequent replacement of the specifications and styles of the LCD placement platform, the workload is greatly increased and the workload is reduced. Productivity;

3. The existing LCD loading device has a complicated structure and a large floor space, thereby causing congestion between devices, and has a great influence on processes such as loading and spare parts of the LCD;

4. Most of the COF feeding and pressing of finished parts are manually intervened. On the one hand, it is easy to cause different degrees of pollution to COF parts and finished parts, which reduces the quality of pressing, and on the other hand, greatly reduces the efficiency of loading and unloading. As a result, the pressing efficiency is low.

In view of this, it is necessary to develop a fully automatic pre-presser for pressing COF and LCD to solve the above problems.
