Description

Technical Field

[0001] The patent of this invention relates to the technical field of screen module bonding, and mainly relates to a device and method for bonding LCM screen modules using optical fiber positioning. Background Art

[0002] LCM module attachment is an important part of the LCD module manufacturing process. This process involves accurately attaching various components, such as LCD screen, drive circuit, backlight module, etc., together to form a complete LCM module. LCM module attachment is a key part of the LCD module manufacturing process, and its quality directly affects the display effect and performance of the LCM module.

[0003] The current bonding process is initially performed by an automatic bonding machine. Due to various reasons, the accuracy of repeated positioning of the automatic bonding machine does not meet the bonding yield requirements of LCM products. Defective products that do not meet the bonding accuracy requirements will be intercepted by the equipment and transferred to manual repair and manual secondary bonding. During manual bonding, the larger module needs to be positioned first, and the smaller module is attached within the limited range along the limit line. However, the allowable error of the attachment range is very small. When employees perform manual repair and attachment, they need to repeat the manual alignment many times to meet the repair and bonding requirements, which reduces work efficiency. In this regard, we propose a device and method for LCM screen module bonding using optical fiber positioning. Summary of the invention
