Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screens of wearable terminals, in particular to a structure for preventing ACF glue overflow during FOF bonding of a wearable terminal. Background Art
[0002] In current existing touch display screens, the FPC of the touch screen is usually connected to the FPC of the display screen, and then connected to the terminal device through the FPC of the display screen. This method can save the cost of the terminal device and reduce the space of the terminal device. For example, the FPC of the touch screen is connected to the FPC of the display screen through devices such as ACF or manually (i.e., the FOF process). However, in the touch display screen of wearable products, in order to ensure the compact size of the wearable products, the gold fingers of the FPC of the touch screen are closely attached to the edge of the outer shape support surface of the FPC of the display screen. After the ACF is attached and pre-bonded, the ACF glue overflows, causing the ACF glue to stick to the bonding press head, which easily causes defective product pressing. At the same time, operators need to frequently clean the ACF equipment platform. Summary of the Invention
[0003] The utility model provides a structure for preventing ACF glue overflow during FOF bonding of a wearable terminal for the problems of the prior art, which can prevent the ACF glue from overflowing and sticking to the bonding and pressing platform, avoid causing defective bonding and pressing, reduce the number of cleanings of the bonding platform, has a novel structure and ingenious design, improves the working reliability, and solves the problems of defective FPC bonding and pressing and the cumbersome cleaning of the bonding platform.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] The utility model provides a structure for preventing ACF glue overflow during FOF bonding of a wearable terminal, including a touch screen FPC and a display screen FPC. A gold finger positioning groove is arranged at the display screen FPC. One end of the touch screen FPC is provided with a gold finger component, and the gold finger component is bonded in the gold finger positioning groove through ACF glue. A relief notch is arranged on one side of the gold finger positioning groove close to the touch screen FPC, and the distance between the gold finger component and the relief notch is greater than or equal to 0.6 mm.
[0006] Wherein, a first positioning MARK point is arranged at the touch screen FPC close to the gold finger component, and a second positioning MARK point is arranged in the gold finger positioning groove, and the first positioning MARK point and the second positioning MARK point are arranged correspondingly.
[0007] Wherein, the gold finger component is bonded in the gold finger positioning groove through ACF glue by using an ACF device.
[0008] Beneficial effects of the present utility model:
[0009] Since the distance between the gold finger component and the avoidance notch of the present utility model is greater than or equal to 0.6 mm, the overflow part of the ACF glue after bonding is still on the FPC and will not overflow onto the bonding and pressing platform, which can prevent the ACF glue from overflowing and sticking to the bonding and pressing platform. At the same time, it can avoid poor bonding and pressing, and can also reduce the number of cleanings of the bonding platform. The structure is novel and ingeniously designed, improving the working reliability and solving the problems of poor FPC bonding and pressing and the tedious cleaning of the bonding platform. Description of the drawings
[0010] Figure 1 It is a schematic structural diagram of a structure for preventing ACF glue overflow in the FOF bonding of a wearable terminal of the present utility model.
