[0002] A circuit board can be called a printed circuit board or a printed wiring board, and its English name is PCB. The FPC circuit board (the FPC circuit board is also called a flexible circuit board. A flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. When a printed circuit board needs to be cut during the assembly process, a V-cut circuit board cutting machine, a milling cutter type circuit board cutting machine, an electric-hybrid design, and milling cutter cutting are required. It is especially suitable for dividing precision SMD thin plates, aluminum circuit boards, and operates in a guillotine manner.

[0003] In the existing circuit board cutting machine for printed circuit board assemblies, two groups of suction cups are used to adsorb the cover plate or the circuit board during use, which wastes a lot of costs. At the same time, the existing cover plates are directly fixed on the cylinder, lacking a certain degree of stability during the cutting process. The pressure of the cylinder will damage sensitive components on the circuit board, thus affecting the cutting effect. Therefore, a fully automatic circuit board cutting machine for printed circuit board assemblies needs to be proposed. Content of the Utility Model

[0025] Working principle: When using this fully automatic circuit board component cutting machine, first connect to the external power supply. Then connect multiple suction cup rods 17 on the limit frame 16 to an external air pump through an air pipe 18. The driving mechanism linearly pushes the suction cup frame 14 and the suction cup rods 17 to descend to adsorb the circuit board. When contacting the circuit board, turn off the switch of the sixth servo module 13. Then, for the adsorbed circuit board, turn on the switch of the servo motor 10. When current passes through the motor coil, a magnetic field will be generated, causing the rotor of the motor to generate magnetic force, thereby generating a rotational force to drive the screw rod 11 to rotate. The rotation drives the manipulator bracket 12 and the suction cup frame 14 to move left and right simultaneously. After moving the circuit board above the fixed fixture 4, turn off the external air pump switch and the servo motor 10 switch. Then place the circuit board on the fixed fixture 4. Then turn on the switch of the fourth servo module 2 to drive the workbench surface 3 and the fixed fixture 4 to slide to the cutting area. After sliding to the position, turn off the switch of the fourth servo module 2. Then, through the operation of moving the suction cup frame 14 just now, adsorb the cover plate 5 onto the circuit board on the fixed fixture 4. Let the cover plate 5 fall onto the positioning pins 7 on both sides of the fixed fixture 4 for positioning. Then turn on the switch of the first servo module 20 to drive the first cutting head fixing support 21 and the milling cutter 25 below to move above the circuit board. After moving above, turn off the switch of the first servo module 20. Next, turn on the switch of the servo motor 22 to drive the power source of the cutting head, and the milling cutter 25 descends to cut the surface of the circuit board. When cutting, turn on the switch of the vacuum pump 27, and adsorb the dust generated during the cutting of the milling cutter 25 through the vacuum hose 26. Then, after the milling cutter 25 cuts through the circuit board to the bottom, when the circuit board cutting is completed, turn off the switch of the vacuum pump 27. Finally, cut off the external power supply. Just like this, the use process of this fully automatic circuit board component cutting machine is completed.
