The terms "first", "second", "far from", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0021] Refer to Figure 1In an embodiment of a touch FPC binding structure with a mark grabbing and positioning function, the binding structure includes an FPC binding area, on which a plurality of first pin interfaces 1 and second pin interfaces 2 are provided. The second pin interfaces 2 are located on the left and right sides of the FPC binding area. A plurality of first pins 1 are arranged in sequence between two second pin interfaces 2. The second pin interface 2 includes an interface area 21 and a mark grabbing alignment area 22 extending away from the adjacent first pin. The pins of the touch screen are connected and bound to the pin interfaces 1 and 2 on the FPC binding area, without the need to separately set a mark grabbing alignment area. The binding device performs mark grabbing alignment through the mark grabbing alignment area 22 of the second pin interface 2 for precise binding, reducing the risk of poor binding.
[0022] In this embodiment, a notch 3 extending from the FPC binding area to the substrate is provided on the FPC binding area. There is 1 notch, and the FPC binding area is divided into independent binding partitions according to actual needs.
[0023] It should be noted that in other embodiments, there may also be multiple notches 3. Through reasonable notch design, it can help the device or operator more accurately position the binding parts (such as ITO or other substrates) of the FPC and the touch screen, reduce the poor binding caused by position deviation, and simplify the process flow of the binding process.
[0024] In this embodiment, each binding partition is provided with a set of first pin interfaces 1 and second pin interfaces 2, and a plurality of first pin interfaces 1 within the partition are arranged in sequence between two second pin interfaces 2.
[0025] In this embodiment, for the design of the mark grabbing alignment area, refer to Figure 2 , the mark grabbing alignment area 22 of the second pin interface 2 is set in a cross shape, which can be used as a cross mark for the binding to grab and align during FPC binding.
[0026] Preferably, a MARK point can also be set at the center of the cross shape to ensure that the device clearly grabs the position of the Mark point, improve the mark grabbing accuracy, and reduce the risk of binding deviation.
[0027] It should be noted that the shape setting of the mark grabbing alignment area 22 in this embodiment does not constitute a limitation to the present invention.
[0028] In this embodiment, the first and second pin interfaces 1 and 2 are integrally provided. The interface areas 21 of the first pin interface 1 and the second pin interface 2 have the same size. The interface areas 21 of the first pin interface 1 and the second pin interface 2 include a substrate and pins provided on the substrate.
[0029] In this embodiment, the first and second pin interfaces 1 and 2 are connected to the pins on the binding part using ACF, so as to form a stable conductive channel between the pins of the binding part and the FPC.
[0030] In this embodiment, a groove may be provided at the connection between the label grabbing alignment area 22 and the interface area 21, so that the label grabbing alignment area 22 is avoided from the ACF coverage range, and the FPC is prevented from being pulled off during the label grabbing alignment process, which may easily lead to poor electrical performance of the product.
[0031] In summary, in this embodiment, by extending the second pin interface 2 on the bonding area outward to set the label grabbing alignment area 22, it is convenient for the bonding device to perform label grabbing alignment without additionally setting a label grabbing alignment area on the bonding area, simplifying the alignment design, reducing the alignment difficulty, making the bonding more accurate, and reducing the risk of bonding defects.
[0032] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
