Description

Technical Field

[0001] This utility model relates to the field of touch panel manufacturing technology, and in particular to a device for bonding iron parts and glass. Background Technology

[0002] A touchpad (or trackpad) is a device on a laptop computer that uses the movement of a user's finger to control cursor movement. Its core structure is a touch element, which involves a metal component. A glass component needs to be attached to the metal component, and a PCB board is mounted on the glass component. Before the metal component arrives, its upper surface is covered with multiple small blue films with protective films on their surfaces. These protective films need to be removed first so that the blue films can adhere to the glass component. It is easy for small blue films to be missing, which reduces adhesion. In addition, because there are many small blue films and they are relatively small, the protective films are also easy to miss, which may result in poor adhesion. Furthermore, the absence of small blue films can also affect the product molding thickness, potentially leading to product defects.

[0003] Touch components are precision components used in laptops, and the requirements for bonding accuracy are relatively high. Ordinary devices are prone to misalignment. In addition, the reliability of the bonding also affects the product quality.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a device for bonding iron parts and glass. Utility Model Content
