The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.
[0021] It should be noted that the terms “first surface”, “second surface” and similar expressions used herein are only for illustrative purposes and do not represent the only implementation manner.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0023] See also Figure 1 , Figure 2 The special-shaped cover plate limiting structure in the first embodiment includes a special-shaped cover plate body 1, a carrier sheet 2, and a double-sided adhesive 3. The carrier sheet 2 is adhered to the first surface of the special-shaped cover plate body 1 by the double-sided adhesive 3. The size of the carrier sheet 2 can at least completely cover the special-shaped cover plate body 1. In this way, the limiting of the special-shaped cover plate body 1 by the bonding fixture 4 can be determined according to the shape and size of the carrier sheet 2, which reduces the difficulty of manufacturing the bonding fixture 4 and improves the bonding efficiency and bonding accuracy.
[0024] In this embodiment, the carrier sheet 2 is a rectangular hard PET carrier sheet with a regular shape, which is convenient for laminating and limiting. The hard PET material can maintain stable performance in a wide temperature range. On the other hand, it also has good impact resistance and can maintain the integrity of the structure when subjected to external force impact, thereby ensuring the stability and reliability of the limiting structure. In addition, during the laminating process, the wear resistance and high strength of PET can protect the special-shaped cover from being damaged.
[0025] In this embodiment, the carrier sheet 2 and the special-shaped cover plate body 1 are bonded with a weak adhesive double-sided adhesive 3 having a low-temperature release characteristic, the first surface of the double-sided adhesive 3 completely covers the special-shaped cover plate body 1, and the second surface of the double-sided adhesive 3 is covered by the carrier sheet 2. In this way, after bonding, the bonded semi-finished product is placed under low-temperature conditions, the hard PET carrier sheet 2 can be separated, and it is not easy to leave obvious marks on the special-shaped cover plate body 1, and finally a bonded finished product is obtained, thereby improving the bonding yield.
[0026] See also Figure 3 , Figure 4The laminating fixture 4 in the second embodiment uses the above-mentioned special-shaped cover plate limiting structure for limiting laminating. The special-shaped cover plate limiting area 41 on the fixture is used to limit the above-mentioned special-shaped cover plate limiting structure, and the display screen limiting area 42 limits the display screen 5 to be laminated with the second surface of the special-shaped cover plate body 1. The shape of the special-shaped cover plate limiting area 41 matches the carrier sheet 2, and the shape of the display screen limiting area 42 matches the display screen 5 to be laminated. In this way, the laminating fixture 4 can simply limit the special-shaped cover plate limiting structure and the display screen 5.
[0027] During bonding, the display screen 5 is first placed in the display screen limiting area 42 of the bonding fixture 4, and then the above-mentioned special-shaped cover plate limiting structure is placed. Therefore, the bonding fixture 4 only needs to limit the carrier sheet 2 and the display screen 5 to achieve high-precision attachment, improve the product bonding yield, and reduce the development cost of the bonding fixture.
[0028] In this embodiment, the display screen 5 to be bonded may be a TFT, LCD, or OLED display screen.
[0029] In this embodiment, the special-shaped cover plate limiting area 41 can be additionally provided with a square or semicircular pick-up and placement position to facilitate the pick-up and placement of the special-shaped cover plate limiting structure.
[0030] In this embodiment, a soft silicone pad may be provided in the display screen limiting area 42 to effectively reduce the friction and pressure between the display screen and the display screen, thereby avoiding leaving marks or damage.
[0031] The utility model adheres a hard and regular PET carrier sheet 2 to the special-shaped cover plate body 1 as a limiting structure, so that the fitting fixture 4 does not need to be limited according to the actual shape of the special-shaped cover plate body 1, but only needs to be limited according to the shape of the carrier sheet 2, thereby reducing the manufacturing difficulty of the fitting fixture 4 and improving the fitting accuracy.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
