Description

Technical Field

[0002] A notebook backlit touchpad is a notebook computer component that integrates touch input and backlight functions. During the touchpad production process, a press machine is required to gradually fit the printed board and the substrate under a set pressure to press the printed board and the substrate together to form a touchpad.

[0003] After searching, the application with patent number 202110836832.7 discloses an automatic laminating device for a touch panel, including a laminating platform, a lifting mechanism, a rolling laminating mechanism, and a positioner for positioning a substrate covered with a printed board. The lifting mechanism is supported and installed on the laminating platform through a support frame, and the rolling laminating mechanism is hoisted on the support frame through the lifting mechanism and is located directly above the positioner. The rolling laminating mechanism has at least one cylindrical roller;

[0004] Although the touch panel automatic bonding device gradually bonds the printed board and the substrate under a set pressure by rolling the cylindrical roller, the cylindrical roller of the touch panel automatic bonding device rolls from one side of the printed board and the substrate to the other side, and the air between the printed board and the substrate can only be discharged from one side. The air discharge rate is slow, which can easily cause bubbles to form between the printed board and the substrate. In addition, the push plate is driven by the clamping cylinder to clamp the printing board and the substrate on both sides, which can easily cause the stroke of the output shaft of the clamping cylinder on both sides to be inconsistent, thereby causing the position of the printed board and the substrate to shift.

[0005] Therefore, we propose an automatic laminating device for a notebook backlight touch panel. Summary of the invention
