A pressure strip 16 is fixedly installed on the top of each feeding table 8 close to the electromagnet 10, and racks 17 are fixedly installed on adjacent sides of the two feeding tables 8. A gear 13 is rotatably installed on the top of the workbench 1, and the gear 13 is meshed with the two racks 17. Two laser cutting machines 11 and a servo motor 12 are fixedly installed on one side of the rear baffle 18, and the output end of the servo motor 12 is fixedly installed with the rotation center of the top of the gear 13.

[0024] When in use, the circuit board to be cut is placed in the groove at the top of the feeding table 8. The groove at the top of the feeding table 8 is consistent with the width of the circuit board. After laser cutting, the circuit board body is heated. Ventilation holes are opened on the surface of the feeding table 8 to accelerate the heat dissipation of the circuit board. The pressure strip 16 is installed to press the top of the circuit board, and then the push block 9 is installed in the groove at the top of the feeding table 8, and one side of it is against the end of the circuit board away from the laser cutting machine 11.

The two slag discharge ports correspond to the cutting ends of the two laser cutting machines 11 respectively. A collecting box 6 is provided under the two slag discharge ports. The two collecting boxes 6 can be removably installed at the bottom of the workbench 1.
