It is the preferred display for many computers now. Its working principle is to energize the liquid crystal solution between two polarized materials to rearrange the crystals to form the desired image. When producing LCD screens, it needs to be bonded, but the existing bonding machines still have some defects when used, such as:

[0003] Application number 202022513526.3, a panel laminating device for liquid crystal display production capable of precise positioning, when in use, achieves precise positioning by arranging the panel laminating device body, square plug-in slot, fixing slot, cavity, fixing mechanism, support plate, fixing rod, extrusion spring, traction rod, propulsion handle, square plug-in block, scale positioning plate, limit slot, limit block, circular matching hole and circular through hole for coordinated use.

[0028] As a preferred technical solution of the present invention, the following steps are included:

[0029] Step 1: Place the glass panel frame to be bonded with the glued side facing up on the No. 1 feeder in order. Then start the motor and drive the glass panel to move to the right and move to the rightmost end of the No. 1 feeder.

[0030] Step 2: Hydraulic rod No. 1 is activated and extended, causing pneumatic suction head No. 1 to descend and hold the center of the glass panel. Then hydraulic rod No. 1 is activated and retracted.

[0034] Step 6: The No. 3 hydraulic rod is activated and extended, so that the liquid crystal substrate is sucked by the two No. 2 pneumatic suction heads. Then the clamp releases the substrate and retracts. Then the No. 4 hydraulic rod is activated and lifts the workbench upward, so that the glass panel and the liquid crystal substrate are bonded. Then the No. 2 hydraulic rod is activated and extended, so that the glass panel and the liquid crystal substrate are pressed together.

[0035] Step 7: Hydraulic rod No. 4 starts and retracts, causing the workbench to drop back to its original position. At the same time, hydraulic rod No. 2 starts and lifts the pressing plate to its original position. The clamp then re-enters the protective cover and clamps the bonded LCD screen. The pneumatic adsorption head No. 2 is released and retracted to its original position. The clamp then moves forward, places the LCD screen on the No. 2 feeder, and releases it, making it easier for workers to take it away.

[0038] 2. The present invention is provided with a workbench, and an air outlet is provided on the workbench. The front end of the workbench is connected to an air compressor through a pipeline, so that air can be discharged from the air outlet. When the glass panel is positioned on the workbench, the glass panel is suspended above the workbench, thereby avoiding scratches between the glass panel and the workbench, reducing scratches on the glass panel, and improving product quality.

The laser locator transmitting end 27 is driven to move. When the laser locator transmitting end 27 is aligned with the laser locator receiving end 31, the liquid crystal substrate stops moving.

[0060] Step 6: The No. 3 hydraulic rod 11 is activated and extended, thereby sucking the liquid crystal substrate through the two No. 2 pneumatic suction heads 12. Then the clamper 15 releases the substrate and retracts. Then the No. 4 hydraulic rod 33 is activated and lifts the workbench 4 upward, so that the glass panel and the liquid crystal substrate are bonded. Then the No. 2 hydraulic rod 10 is activated and extended, thereby pressing the glass panel and the liquid crystal substrate together.

[0061] Step 7: The No. 4 hydraulic rod 33 is started and retracted, so that the workbench 4 is lowered back to its original position. At the same time, the No. 2 hydraulic rod 10 is started and the pressing plate 13 is lifted to its original position. Then the clamp 15 re-extends into the interior of the protective cover 9 and clamps the bonded LCD screen. Then the No. 2 pneumatic adsorption head 12 is released and retracted to its original position. Then the clamp 15 moves forward and places the LCD screen on the No. 2 feeder 19 and releases it, making it convenient for workers to take it away.

10. A laminating method for an automatic laminating machine capable of precise positioning according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Place the glass panel frame to be bonded with the glued side facing up on the No. 1 feeder in order. Then start the motor and drive the glass panel to move to the right and move to the rightmost end of the No. 1 feeder. Step 2: Hydraulic rod No. 1 is activated and extended, causing pneumatic suction head No. 1 to descend and hold the center of the glass panel. Then hydraulic rod No. 1 is activated and retracted. At the same time, the motor is started and drives the turntable to rotate, thereby rotating the rotating frame and placing the glass panel on the workbench. Step 3: The air compressor connected to the quick connector through the pipe is started and the air is discharged through the air outlet on the workbench, so that the glass panel on the workbench is suspended. Then the motor is started and drives the No. 2 threaded rod to rotate, so that the slider moves toward the middle and the push plate moves toward the middle, thus moving the glass panel to the center of the workbench. The pressure sensor monitors the force of the push plate pushing the glass panel to prevent the push plate from damaging the glass panel. Then the air compressor is turned off, so that the glass panel falls stably in the center of the workbench. Step 4: Place the LCD substrate on the No. 2 feeder. The motor starts and drives the roller to rotate, thereby moving the LCD substrate to the back of the No. 2 feeder. At the same time, the object recognition and positioning camera monitors the LCD substrate and stops it at the appropriate position. Step 5: The clamps are located on both sides of the liquid crystal substrate. At the same time, the pneumatic telescopic rod is started, and the clamps clamp the liquid crystal substrate. At the same time, the motor at the front end of the slide is started, and drives the No. 1 threaded rod to rotate, thereby extending the guide rail and extending the liquid crystal substrate into the protective cover. The laser locator transmitter is driven to move. When the laser locator transmitter is aligned with the laser locator receiver, the liquid crystal substrate stops moving. Step 6: The No. 3 hydraulic rod is activated and extended, so that the liquid crystal substrate is sucked by the two No. 2 pneumatic suction heads. Then the clamp releases the substrate and retracts. Then the No. 4 hydraulic rod is activated and lifts the workbench upward, so that the glass panel and the liquid crystal substrate are bonded. Then the No. 2 hydraulic rod is activated and extended, so that the glass panel and the liquid crystal substrate are pressed together. Step 7: Hydraulic rod No. 4 starts and retracts, causing the workbench to drop back to its original position. At the same time, hydraulic rod No. 2 starts and lifts the pressing plate to its original position. The clamp then re-enters the protective cover and clamps the bonded LCD screen. The pneumatic adsorption head No. 2 is released and retracted to its original position. The clamp then moves forward, places the LCD screen on the No. 2 feeder, and releases it, making it easier for workers to take it away.
