Description

Technical Field

[0001] This application belongs to the field of display assembly technology, and more specifically, relates to a tablet computer screen bonding and positioning device. Background Technology

[0002] With the development of science and technology, the use of tablet computers has greatly increased the convenience of people's work. By using tablet computers, people can perform tasks such as office work, shopping, and video calls. Because tablet computers are easier to carry than traditional computers and laptops, people choose to use tablet computers when they go out in their daily lives.

[0003] Currently, tablet manufacturing involves assembling the casing and display screen. The casing has an inner recessed platform, and the back edge of the display screen is bonded to the platform with double-sided adhesive. Due to manufacturing tolerances, the display screen is slightly smaller than the dimensions enclosed by the platform's sidewalls, resulting in a gap between the display screen and the platform's sidewalls after assembly. Since current assembly methods mostly involve manually placing the casing into a specialized fixture and then using suction cups to attach the display screen to the casing, the unevenness of the gaps between the display screen and the casing's four sides, relying on visual judgment, significantly impacts the product's appearance.
