Embodiment Construction

[0023] In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0024] figure 2 It is a schematic structural diagram of a fitting tool for a curved screen shown in Embodiment 1 of the present invention. The laminating tool includes a base 1 and a pressing block 2. During lamination, the protective glass is fixed in the upper fixture, the display panel is placed between the pressing block 2 and the protective glass, and the pressing block 2 is arranged on the base 1 surface, and the base 1 can drive the pressing block 2 to move upward, so as to fit the display panel and the inner su...

Abstract

The invention discloses a laminating tool for a curved screen, comprising: a base and a pressing block arranged on the base, the pressing block is in the shape of a cuboid, and the edge of the top surface is configured to be aligned with the curved screen The four sides of the pressing block are inwardly recessed to form concave arc surfaces; wherein the fitting tool also includes a support member for supporting the four corners of the top surface of the pressing block. The laminating tool of the present invention adds supporting parts, which can provide support to the four corners of the top surface of the pressing block when the pressing block is pressed, so as to increase the pressure of the four corners of the pressing block on the protective glass, so that the display panel and the protective glass can be separated from each other. It is difficult to generate air bubbles at the four corners, which improves the yield of the curved screen.

Description

technical field [0001] The present invention relates to the technical field of display screen manufacturing. More specifically, it relates to a bonding tool for processing curved screens. Background technique [0002] At present, curved screens have been gradually applied to smartphones. For large-screen mobile phones, curved screens are easier to operate and have better visual effects. However, the fitting effect of the curved screen directly affects the display effect of the curved display device. The existing vacuum bonding technology cannot provide enough pressure at the four corners, and bubbles are easily generated at the four corners of the display screen, resulting in poor display effect of the product. [0003] At present, there is a curved screen fitting tool, such as figure 1 As shown, it includes a base 1' and a rubber pressing block 2', a cover glass 3 (Cover Glass, CG) is fixed in the upper fixture, the display module is placed between the pressing block 2'...
