The working principle of the PCB circuit board fusing device provided by the utility model is as follows:

Step 1: The circuit board to be fused is brought into the housing 1 via the conveying device 23. Under the action of the two straightening wheel groups 25, the circuit board enters the housing 1 at a suitable position, and then is conveyed to the silicone heat conductive plate 6, blocked by the limit baffle 13, and the two heating plates 5 begin to heat. The upper hydraulic rod 2 is pushed downward to clamp the circuit board to be fused and continue to press down. The sleeve rod 12 is forced to shrink to a suitable position until the pressure is maintained at a suitable size, and the circuit board begins to be fused;

The second step: when the circuit board is fused, the gear box 16 moves through the toothed rod 15, thereby driving the electric control suction cup 21 to move. When it runs above the hot pressing mechanism, the hydraulic rod 20 pushes the electric control suction cup 21 out and firmly sucks the circuit board. The hydraulic rod 20 contracts, and the gear box 16 moves in the opposite direction through the toothed rod 15, driving the electric control suction cup 21 to the top of the conveying device 24. The suction cup is powered off, and the circuit board is placed on the conveying device 24. Under the action of the two straightening wheel groups 25, it is taken out of the device through the conveying device 24 at a suitable position.
