The negative pressure pump 701 is powered on to generate suction, which enters the filter tube 702 and is transmitted to the negative pressure plate 704. The negative pressure suction is transmitted to the inside of the negative pressure seat 201 through the negative pressure plate 704. The negative pressure suction inside the negative pressure seat 201 negatively adsorbs and positions the touch screen and the flexible circuit board through the negative pressure hole. At the same time, the pneumatic fan blades 206 are driven to rotate under the action of negative pressure suction, and the rotating pneumatic fan blades 206 drive the shaft rod 203 to be pulled and moved through the traction rod 207.

When the controller 102 calculates that the horizontal movement distance reaches the set value, the controller 102 controls the servo motor B404 to stop running. At the same time, the height position of the welding head 503 is measured in real time through the distance sensor C505, and the measured electrical signal is transmitted to the controller 102 for calculation, so that the welding head 503 can move vertically to avoid obstacles; When the welding head 503 reaches the butt welding position, the electric telescopic rod 501 drives the guide slide bar frame 502 to move downward, and the downward moving guide slide bar frame 502 drives the welding head 503 to move downward to the butt joint of the touch screen and the flexible circuit board. At the same time, the pressure of the welding head 503 is monitored in real time through the pressure sensor, and the monitoring electrical signal is transmitted to the controller 102 for calculation. When the calculated pressure electrical signal reaches the set value, the controller 102 controls the electric telescopic rod 501 to stop running, and provides power to the welding head 503 through the hot pressure welding appliance 103, so as to weld the butt joint of the touch screen and the flexible circuit board; At the same time, the dust and foreign matter on the top of the negative pressure seat 201 are adsorbed and cleaned through the negative pressure hole, and the filtered air is discharged through the muffler 705. The sound of the exhaust gas is reduced by the silencing and noise reduction function of the muffler 705. The dust and foreign matter are transported to the filter tube 702 through the negative pressure plate 704, and filtered by the filter element 703 inside the filter tube 702. The filtered dust and foreign matter are transported to the inside of the collection box 6 through the one-way valve tube for collection.
