How does the screen pressing machine work?

The working principle is to put the mobile phone LCD screen and the glass cover plate in the vacuum box, use the cylinder pressure of the machine to lower the inner mold of the vacuum cylinder, and completely press the glass cover plate and the LCD screen under the vacuum cylinder, which is to use PLC as the control center of the whole system. To achieve the whole process of attaching operation.

The PLC is used as the control center of the whole system, and the PLC outputs the pulse control pneumatic components by the specific pulse output port, so that the LCD alternate rotating platform moves accurately to the specified position in the circular direction according to the predetermined position.

Principle: PLC is used as the control center of the whole system to realize the whole process of attaching operation.

A programmable memory is used to store instructions for performing operations such as logic operations, sequence control, timing, counting, and arithmetic operations, and various types of mechanical equipment or production processes are controlled through digital or analog inputs and outputs.

When a programmable logic controller is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refresh. Throughout the operation, the PLC's CPU repeats the above three phases at a certain scan speed.

The working principle of the screen pressing machine is to place the mobile phone LCD screen and the glass cover plate in the vacuum box in the vacuum environment, use the cylinder pressure of the machine to lower the inner mold of the vacuum cylinder, and completely press the glass cover plate and the LCD screen placed in the lower mold of the vacuum cylinder.

The biggest difference of the automatic OCA vacuum laminating machine is that the machine itself adds automation hardware, which makes the tray automatically imported and automatically exported after pressing, and for some factories, it will be more convenient and fast for users with large quantities.

When separating and removing the glue, pay attention to the wire, when separating the cover plate, when separating the steel wire and separating the screen line, you need to pay attention to the wire not to hurt the wire, and you also need to pay attention to the wire when cleaning the residual glue, and many problems are also in the separation and glue removal here.

Paste OCA glue or polarized light as much as possible to avoid bubbles, before sticking OCA to ensure that there are no bubbles or tiny bubbles, too many bubbles and then fit and defoam the effect is not good.

The main working principle is to use PLC as the control center of the whole system to realize the whole process of attachment operation, PLC by the specific pulse output port output pulse control pneumatic components, so that the LCD alternate rotation platform according to the predetermined position to do the circular direction of accurate movement to the specified position.

Mainly for the hard-to-hard combination between optical and rigid materials, such as optical double-sided tape (OCA) bonding between two layers of glass substrates, and the components are pressed together under vacuum, which effectively overcomes the process defects such as bubbles and rainbow patterns, and is a necessary process in the combination process of touch panels.

The principle of Zhan Wangxing screen pressing machine is to put the mobile phone LCD screen and glass cover plate in the vacuum box in the vacuum environment, use the cylinder pressure of the machine to lower the inner mold of the vacuum cylinder, and completely press the glass cover plate and the LCD screen placed in the lower mold of the vacuum cylinder. In order to complete the key process in the repair of mobile phone screens, that is, the "OCA lamination process".

1. The main purpose of the screen pressing machine is to replace the LCD screen. It is also called a mobile phone screen presser.

2. After the mobile phone with a broken screen is turned on, it can be used as usual, it can be displayed, and the touch is also sensitive, which is generally broken is the outermost protective glass. The cover glass of most mobile phone screens is replaceable. The so-called "pressure screen" is to replace the outer protective glass.

3. The mobile phone screen is divided into protective glass, touch screen and display screen from the outside to the inside, as long as the protective glass is broken, it can be done with the screen pressing device. If even the display screen is broken, then you can't just replace one piece of protective glass, you have to replace it all.

The tools and materials required for screen pressing are not complicated, mainly a set of professional equipment and mobile phone glass. Before pressing the screen, use a separator to separate the broken mobile phone glass from the body, and then use the device to press the new glass screen and the mobile phone together, the process only takes about 20 minutes.

4. Although the screen pressing is cheap, it is still recommended that users use the original screen. The screen of the pressure screen is produced by non-original manufacturers, and there is not only a difference between the two, but also a gap in quality. Not only the gloss, but also the sensitivity of the screen will be a little worse.

Repair the mobile phone LCD machine (also called the screen press).

The role of the screen pressing machine:

1. OCA glue can be used to fill the gap, and the display panel is closely attached to the touch screen, so that dust and water vapor have nowhere to enter, and the cleanliness of the screen is maintained.

2. It can be fixed directly by buckle or lock screw, which can reduce the assembly problems caused by fitting deviations, and at the same time simplify the assembly process and reduce the assembly cost.

3. The use of screen pressing machine can realize the optical glue between the touch screen and the display screen, only increasing the thickness of 25 m-50 m, and the thinner body improves the product grade and highlights the technical content.

4. The screen pressing machine equipment is equipped with a multi-directional fine-tuning device, so it is also suitable for products of different shapes, and with special fixtures, it can also fit products with irregular shapes such as arcs and diamonds.
