Description

TECHNICAL FIELD

[0001] The utility model relates to electronic product screen bonding technical field more specifically, it relates to a kind of electronic product screen bonding pressure maintaining fixture. BACKGROUND

[0002] When assembling electronic products such as mobile phones and tablet computers, the screen and the shell are usually bonded to ensure that the screen is firmly fixed in the shell. Before the adhesive solidifies, a pressure maintaining fixture is used to apply pressure to the electronic product to ensure that there is no gap between the screen and the shell, thereby preventing problems such as a decrease in screen sealing and light leakage.

[0003] In the patent document with publication number CN206181716U, an electronic product screen bonding pressure maintaining fixture is proposed. The device includes a base plate, a fixed groove on the surface of the base plate, and a pressure plate covering the surface of the base plate. It also includes a plurality of fixed holes on the base plate surrounding the fixed groove. The bottom of the pressure plate is provided with a plurality of fixed blocks corresponding to the fixed holes, which can extend into the fixed holes. The inner side of the fixed block is provided with an undercut. The pressure plate of the utility model can effectively compress the screen to ensure that the screen and the electronic product are firmly attached before the adhesive solidifies. This ultimately avoids the occurrence of defects such as a decrease in screen sealing and light leakage, effectively improving the quality of the electronic product produced.

[0004] However, the size of the fixed groove is fixed during use, and cannot be adjusted according to the size of different electronic products, so that the entire device can only bond and maintain pressure on the screen of electronic products of the same size. When bonding and maintaining pressure on the screens of electronic products of different sizes, different size pressure maintaining fixtures need to be replaced, thereby reducing the versatility and practicality of the entire device. Secondly, the device can only bond and maintain pressure on electronic product screens of the same thickness during use. When the thickness of the electronic product is different, it may not be placed or pressed, thereby reducing the flexibility of the entire device and not meeting the needs of users.
