Touch panel automation joint system

The present invention provides a machine for manufacturing a touch panel (TP), and more particularly, an automatic machine system for a bonding process of a touch panel, which can increase the automation degree of the process of bonding the glass to the wire.

In the manufacturing process of the touch panel, a process of bonding a sensor terminal and a flexible cable (FPC) is usually required to connect the sensor glass to the touch signal processing module through the cable. This process cannot be soldered with high-temperature lead-tin and needs to be bonded in a low-temperature process. At present, a common technique is to use the anisotropic conductive adhesive (ACF) to join the above-mentioned induction glass and cable. The anisotropic conductive paste is synthesized from resin and conductive particles and is mainly used to connect two different substrates and circuits. The schematic diagram after completion is shown in Figure 1.

Most of the bonding processes of the prior art rely heavily on manpower. The steps first include manually bonding the conductive adhesive A to the electrode layer terminal region of the front surface G1 of the sensing glass G, and attaching the signal transmission portion of the wiring F to the conductive adhesive. A; then, the induction glass G and the discharge line F are placed on the pressing machine (not shown) by manual force, and the front pre-bond is performed at a small pressure. The preloading is to fix the flexible cable F to the terminal of the induction glass G by a predetermined pressure and temperature, and the pressure and temperature of the preloading are determined according to the specifications of the conductive adhesive. After that, the induction glass G is manually turned over and the conductive adhesive A is attached to the ground layer terminal area of the back surface G2, and the grounding part of the wiring line F is attached to the conductive adhesive A to be manually placed into the pressing machine ( Figure omitted), the back preloading. Finally, the induction glass G is placed in the press table together with the cable F (figure omitted), and the main-bond is performed. The pressure is chemically changed and solidified at a higher pressure and a higher temperature, accompanied by The rupture of the conductive particles of the conductive paste causes the flexible cable to form a firm contact with the sensing glass to produce an effective and reliable joint.
