Working principle of screen press machine
Screen press is a common production tool, whose main function is to connect
COF (module) and conductive adhesive explosive particles through pressure
and contact with the material surface to achieve the purpose of pressing.
The following will provide a detailed introduction from the aspects of
machine structure, working principle, maintenance, and upkeep.
The principle of the screen press machine is to use a PLC as the control
center of the entire system to achieve the operation of the entire attachment
process. The PLC outputs pulses from specific pulse output ports to control
the pneumatic components, causing the LCD to rotate alternately and the
platform to move precisely in the circumferential direction to the designated
position according to the predetermined position. It is mainly aimed at the
hard to hard combination between optical and rigid materials, such as
bonding two layers of glass substrates with optical double-sided tape,
and pressing the components in a vacuum state, effectively overcoming
process defects such as bubbles and rainbow patterns. It is an essential
process in the touch panel combination process.
1、 Machine construction
The basic structure of a screen press machine includes the body, press
head, hanger, and personalized customized mesh board. Among them,
the body and hanger are usually made of high-strength aluminum alloy
materials, which have good stability and sturdy quality, and can withstand
high-pressure, high-temperature, and high-speed pressure environments.
Pressure head is a component that applies pressure to the surface of a
material under the action of a machine, usually made of cast iron or steel
material. The magnitude of the pressure can be adjusted through machine operation.
