The bonding pressure head mechanism is widely applied to equipment for connecting a mobile phone screen liquid crystal Display module (LCM) (liquid Display module) with a bonding process in a combined mode; that is, a component for assembling other structural members such as a liquid crystal display, a driver Circuit, an FPC (Flexible Printed Circuit), a backlight, and the like. The mechanical connection and electrical conduction of the liquid crystal glass, the driving circuit and the FPC in the liquid crystal display are core parts of LCM production, wherein the production process of the liquid crystal glass and the FPC is an FOG (film On glass) bonding process, namely, the FPC is carried On a glass panel; the technological equipment in the FOG bonding process uses the pressure head mechanism, and the following is the basic flow of the process:
1. pre-pasting an ACF: pasting an ACF with a specified length at an ITO end of the liquid crystal glass or a pin needing to be bonded of the FPC;
2. pre-bonding: aligning pins of the FPC and the ITO end of the liquid crystal glass through an auxiliary image system on an FOG bonding machine, and prepressing to form preliminary connection;
3. main bonding: under higher temperature and pressure, the pre-bonded LCM product is subjected to main bonding, the electrical connection between the FPC and the liquid crystal glass is realized through the deformation of ACF conductive particles and the breakage of an insulating layer, and meanwhile, two different materials of the FPC and the liquid crystal glass are connected together through the polymerization hardening of ACF glue at high temperature to provide enough mechanical connection strength.

Specifically, the ram of the present compression bonding apparatus is primarily responsible for providing a Z-axis motion that imparts about 150 Ν and 300 Ν to the buffered silica gel ribbon, which is then transmitted to the glass substrate and the IC.
If the circuit between the IC and the glass substrate is well communicated, the pressure head and the screen body supporting surface need to be horizontally adjusted, and the adjustment accuracy directly influences the product effect. The above-mentioned level adjustment is usually achieved by a level adjustment mechanism.
