Description

Technical Field

[0001] The present invention relates to the technical field of precision technology for full lamination of curved and irregular surfaces, and in particular to equipment and method for full lamination of vehicle-mounted irregular curved screens. Background Art

[0002] Currently, the industry lacks good curved hard-to-hard full bonding processes and equipment. The very few existing curved full bonding equipment is not only expensive, has a long delivery time, complex equipment, and a high failure rate, but also has low yield and efficiency. The current technical solution is to place all materials (flat LCD panels and curved glass cover plates), fixing fixtures, positioning and control mechanisms into a vacuum chamber, and then directly apply pressure through mechanisms such as screens and airbags to achieve the full bonding process. This not only requires expensive vacuum pumps (with fixed annual maintenance costs), high-tightness vacuum chambers, control systems, etc., but also has very high equipment costs. It can easily cause liquid crystal breakage, and there are problems such as the inability to completely remove bubbles, low operating efficiency, long production time, and slow output.

In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0030] like Figure 1-3 As shown, on the one hand, the present invention proposes a vehicle-mounted special-shaped curved screen full-bonding device, including a curved glass cover fixing device 1, a plane alignment platform 3, an electrostatic chuck, an anti-stretching material 8, a rolling mechanism, a vertical single-axis manipulator 14, a horizontal single-axis manipulator 15, a frame 16 and a mounting frame 17;

[0031] The curved glass cover fixing device 1 and the flat positioning platform 3 are both arranged horizontally, and the curved glass cover fixing device 1 and the flat positioning platform 3 are arranged side by side on the mounting frame 17 in the longitudinal direction. The electrostatic suction cup is fitted on the bottom of the anti-stretching material 8. The frame 16 is provided with a longitudinal single-axis manipulator 4 for driving the mounting frame 17 to move longitudinally. The frame 16 is provided with a clamping motion mechanism for clamping the anti-stretching material 8 and adjusting the bending radius of the anti-stretching material 8 to utilize the electrostatic suction cup to adsorb the flat liquid crystal panel and attach the flat liquid crystal panel to the curved glass cover under the rolling of the rolling mechanism. The rolling mechanism is arranged on the output end of the vertical single-axis manipulator 14, the vertical single-axis manipulator 14 is arranged on the output end of the horizontal single-axis manipulator 15, and the horizontal single-axis manipulator 15 is arranged on the frame 16.

The clamping mechanism clamps the stretch-resistant material 8 and adjusts its bending radius. The electrostatic chuck deforms along with the stretch-resistant material 8. Before the electrostatic chuck is used to attach the flat LCD panel, the stretch-resistant material 8 is first stretched to a flat state. The flat electrostatic chuck is then used to attach the flat LCD panel to the flat alignment platform 3. The longitudinal uniaxial manipulator 4 then drives the mounting frame 17 to move longitudinally, moving the curved glass cover plate on the curved glass cover plate fixture 1 below the flat LCD panel. The vertical uniaxial manipulator 14 and the transverse uniaxial manipulator 15 then move the rolling mechanism. The clamping mechanism adjusts the curvature of the stretch-resistant material 8, thereby adjusting the curvature of the electrostatic chuck. This allows the rolling mechanism to roll over the stretch-resistant material 8 and press the flat LCD panel downward onto the curved glass cover plate, thereby fully bonding the curved surfaces of the flat LCD panel and the curved glass cover plate. This device can achieve high-yield, bubble-free, and crack-resistant full-surface bonding in atmospheric conditions, even without vacuuming.

A visual camera is used to take pictures of the positioning marks on the flat liquid crystal panel, and a processor is used to control the motor to adjust the angle of the flat alignment platform 3, thereby correcting the angle of the flat liquid crystal panel. Then, the mounting frame 17 is accurately moved by the longitudinal single-axis manipulator 4 to align the curved glass cover plate with the flat liquid crystal panel to ensure the accuracy and quality of the full fit.
