Description

Technical Field

[0001] The utility model relates to the technical field of flexible panels, in particular to an attachment and bonding device. Background Art

[0002] The successful mass production of flexible panels is not only a great boon to the manufacturing of new-generation high-end smartphones and other mobile terminals, but also has a profound impact on the application of consumer electronics due to its low power consumption and bendable characteristics. In the future, flexible panels will be widely used with the continuous penetration of smart terminals. Whether it is a flexible panel or a rigid panel including a glass substrate, it is necessary to bond the wiring layer such as FPC or PCB on the panel to connect the external signal circuit and the drive circuit. Bonding refers to attaching ACF glue (Anisotropic Conductive Film) between the panel (including flexible panel, rigid panel) and the wiring layer such as FPC or PCB and pressing them together.

[0003] However, compared with the previous rigid panels, new problems have also arisen. In the bonding process of flexible panels, the attachment and pressing process also requires multiple transfers of the flexible panels. Since the flexible panels themselves are relatively soft, warping will occur during the process. High-precision alignment cannot be performed on traditional platforms and transfer arms, so the bonding accuracy cannot reach the expected value. Utility Model Content
