Embodiment approach

[0125] In one embodiment, the first slider and the second slider jointly support the fitting pad, and the relative movement between the first slider and the second slider is an active movement.

[0126] In another embodiment, the fitting assembly further includes a support block located between the first slider and the second slider. The first sliding block, the supporting block and the second sliding block jointly support the bonding pad, the supporting block does not move in the second direction, and the movement of the first sliding block and the second sliding block relative to the supporting block is an active movement.

[0127] In yet another embodiment, the fitting assembly further includes a pressing block located between the first slider and the second slider. The first sliding block, the extruding block and the second sliding block jointly support the fitting pad. When the extruding block squeezes into the space between the first sliding block and the second sliding ...

other Embodiment approach

[0412] In other embodiments, if the first clamping claw 41 and the second clamping claw 42 have no degree of freedom in the first direction Z, the first clamping claw 41 and the second clamping claw 42 are positioned through a mechanical structure so that both Or achieve height consistency in the first direction Z between steps 001. If the first clamping claw 41 and the second clamping have no degree of freedom in the second direction X, the first clamping claw 41 and the second clamping claw 42 are The distance from the bonding pad 53 in the second direction X is equal.

[0413] In this embodiment, the bonding method moves the core components in the bonding device 100 to a suitable position first through the equipment alignment step, so as to facilitate the smooth progress of the subsequent steps, reduce the debugging time of the subsequent steps, and also facilitate The lamination accuracy of the curved cover 200 and the flexible screen 300 is increased.

[0414] It can be...

other Embodiment approach

[0439] In other embodiments, when the bonding method is used to bond the curved cover 200 and the flexible screen 300 with a small bending angle in the edge area, the two ends of the carrier film 400 may not be limited to move to the first side 513 and the second side. In the concave region formed by the side surface 523 , the flexibility of the positions of both ends of the carrying film 400 is higher. Similarly, the first side 513 and the second side 523 may not be concavely designed, but planar.

Abstract

The embodiment of the invention discloses a laminating assembly. The laminating assembly comprises a first sliding block, a second sliding block and a laminating pad. The first sliding block and the second sliding block are arranged in the second direction and can be closed to each other and separated from each other. The laminating pad is made of elastic materials, the laminating pad extends fromthe side, away from the second sliding block, of the first sliding block to the side, away from the first sliding block, of the second sliding block, the laminating pad is used for supporting the flexible screen to be stacked and attached to the curved surface cover plate in the first direction, and the first direction is perpendicular to the second direction. According to the laminating assembly, the attaching quality of the curved surface cover plate and the flexible screen can be improved. The embodiment of the invention further discloses a laminating pad and laminating equipment.

Description

technical field [0001] The embodiments of the present application relate to the field of processing technology, and in particular to a bonding component, a bonding pad and bonding equipment. Background technique [0002] With the mass production of domestic flexible screens, the application of flexible screens will experience explosive growth in the future. The form of the screen using the flexible screen is also undergoing subversive changes, from the traditional 2D form to the 3D form. The 3D form can realize the front display and side display of the product, thereby increasing the display area and realizing borderless. [0003] The screen usually includes a curved cover and a flexible screen attached to the curved cover. Traditional bonding equipment generally adopts flat pressing operation to bond curved cover panels and flexible screens. As a result, defects such as bubbles and wrinkles are prone to occur during the bonding process of the curved cover and the flexible...
