Curve surface attaching clamp and attaching method

Abstract

The invention discloses a curve surface attaching clamp and an attaching method, wherein the attaching clamp comprises an upper clamp and a lower clamp, wherein the upper clamp is used for fixing a curve surface touch screen; the lower clamp is used for fixing a curve surface display screen; the lower clamp comprises a first clamp and a second clamp arranged around the first clamp; a first jackingmechanism is arranged under the first clamp and is used for driving the first clamp to do ascending and descending movement; a second jacking mechanism is arranged under the second clamp and is usedfor driving the second clamp to do ascending and descending movement. The existing lower clamp is divided into two independent clamps including the first clamp and the second clamp; the ascending height of the first clamp and the second clamp can be singly controlled; during the attaching, the middle region of the curve surface display screen on the first clamp is firstly attached to the curve surface touch screen; then, the edge part of the curve surface display screen is attached to the curve surface touch screen; bubbles are sufficiently discharged from the middle region of the curve surface display screen to the edge during the attachment; the bubble generation is reduced; the attaching effect is good.

Description

technical field [0001] The invention relates to the technical field of bonding, in particular to a curved surface bonding fixture and a bonding method. Background technique [0002] With the development of display technology, the current mainstream flat-panel display devices are showing more and more disadvantages: poor display effect at both ends and easy visual fatigue. In this case, a curved display device emerges as the times require. A curved display device is a display device with a curved screen. Compared with a flat display screen, its curved design surrounding the direction of the user can provide a wide panoramic image effect. Since any point on the screen is at the same distance from the eyes, no matter whether the objects appear in the center or the edge of the screen, there will be no deformation, and it also reduces the distortion of uneven viewing angle distance when watching at close range, which can make the audience fully Immersed in the wonderful and real...

Problems solved by technology

Using the existing curved surface lamination fixture and lamination method, because the lower fixture is an integrated design, the lower fixture rises as a whole during lamination, and air bubbles are likely to be generated between the curved surface touch screen and the curved display screen, even if the pressure is continued after lamination Degassing can’t fully discharge the bubbles in the central area, and the bonding effect is poor, which will have a negative impact on the display screen and touch sensitivity. When continuous pressure degassing is used, the larger bonding pressure will also have adverse effects and affect the product. quality, low yield
