By using the wind deflector 115, one side of the two fixed plates 17 is blocked. After the first motor 111 is powered on and started, the output end of the first motor 111 rotates, driving the first fan blade 112 to rotate through the output end of the first motor 111. The first fan blade 112 blows air towards the air outlet 114. The air flow is discharged from the middle of the air outlet 114. During the process of the first fan blade 112 blowing air, the surrounding air flow is inhaled. The generated negative pressure air flow passes through the first connecting pipe 15 and the middle of the air inlet pipe 14.

The second baffle 22 fits against the bottom of the air collecting box 13, and the external air flow enters the inside of the air collecting box 13 through the third through-hole 23. Introducing external air through the third through-hole 23 can reduce the excessive pressing of the flexible circuit board caused by excessive suction force, effectively reduce the damage generated during the excessive pressing of the flexible circuit board, enable external air to enter the inside of the air collecting box 13 to reduce the local negative pressure, reduce unnecessary stress on the surface or inside of the flexible circuit board, effectively reduce the excessive pressing of the flexible circuit board, and thus effectively improve the safety of the flexible circuit board lamination.

[0036] Working principle: Push two push rods 116 to slide the wind deflector 115 inside the fixed box 16. Block one side of the two fixed plates 17 through the wind deflector 115. After the first motor 111 is powered on and started, the output end of the first motor 111 rotates, drives the first fan blade 112 to rotate through the output end of the first motor 111, blows air towards the position of the air outlet 114 through the rotation of the first fan blade 112, and the air flow is discharged from the middle of the air outlet 114.

Place the flexible circuit board on multiple groups of first through holes 11 corresponding to the middle of the workbench 10, and the suction force of the negative pressure air flow adsorbs the flexible circuit board flat on the workbench 10, so as to carry out the pressing work on the flexible circuit board. When the flexible circuit board is pressed, pull the push rod 116 to make the wind deflector 115 slide to the other side of the fixed box 16, so that the air flow blows towards the middle of the second connecting pipe 18. The air flow in the middle of the second connecting pipe 18 is discharged into the air collecting box 13 through the exhaust pipe 19 and blows towards the flexible circuit board through the first through hole 11, so that the flexible circuit board is separated from the workbench 10, and the pressed circuit board is taken out. When the negative pressure inside the air collecting box 13 is too large, the negative air flow generates a suction force on the first baffle 21, so that the first baffle 21 slides upward through the two sliding plates 20, and at the same time makes the spring 24 elastically contract. The second baffle 22 fits with the bottom of the air collecting box 13, and the external air flow enters the air collecting box 13 through the third through hole 23. Move the first positioning block 32 to the side wall position of the flexible circuit board, so that the slider 31 slides in the chute 3. When placing materials on the flexible circuit board during the lamination process, make the edges of the materials contact multiple first positioning blocks 32, and be guided by the first positioning blocks 32 to be accurately aligned with the flexible circuit board. Stretch and move the first telescopic rod 4, so that the second positioning block 41 moves to the specified position, and the second positioning block 41 is evenly attached to the side wall of the flexible circuit board pressing material. The first telescopic rod 4 can effectively move the second positioning block 41. When the flexible circuit board pressing material is placed through the first positioning block 32 and the second positioning block 41, it contacts the side wall of the material through multiple balls 5. When the material is placed and moves on the side walls of the first positioning block 32 and the second positioning block 41, multiple balls 5 contact the material and roll at the same time. When blowing air through the second connecting pipe 18, the external air flow first passes through the middle of the air inlet 113, and then enters the fixed box 16 through the middle of the net plate 6. The net plate 6 filters the dust and impurities in the air. After the second motor 72 is powered on and started, the output end of the second motor 72 rotates, drives multiple second fan blades 73 to rotate through the output end of the second motor 72, blows air through multiple second fan blades 73, stretches the second telescopic rod 7, adjusts the second motor 72 to the specified height, and then rotates the second motor 72 through the hinge seat 71, so that the air flow blows towards the flexible circuit board pressing position.Blow away the dust and impurities on the surface of the flexible circuit board. Support the filter screen 81 outside the second fan blade 73 through the support rod 8, and block the dust and impurities in the air through the filter screen 81.
