[0002] Printed circuit boards (PCBs) are providers of electrical connections for electronic components, and their development has a history of over 100 years. Their design is mainly based on layout design. The main advantages of using PCBs are that they greatly reduce wiring and assembly errors, and improve automation and productivity.

[0003] Patent application number 202121923351.1 discloses a cutting fixture for PCB printed circuit board production, including a base and a prefabricated substrate. The base is fixedly connected to the worktable of a laser cutting machine. Support frames are fixedly connected to both sides of the base, and a clamping plate is arranged between the two support frames. Rotating rods are fixedly connected to both sides of the clamping plate, and the rotating rods rotate through the support frames. A rotating device is arranged inside one of the support frames. A rectangular through hole is opened in the middle of the clamping plate, and the prefabricated substrate is arranged inside the rectangular through hole. Several clamping devices are arranged at the position of the rectangular through hole on the clamping plate. The device, by setting the rotating device, facilitates the flipping of the prefabricated substrate by 180 degrees with the assistance of the rotating device, so as to process the other side.

The movement of the worktable 110 causes the connecting plate 106 to move up and down. The fixed slider 105 is inserted into the inner side of the fixed groove 104 to fix the connecting plate 106 to the outer side of the support rod 102. The gear shaft 107 carries the rotating gear 108 to rotate, allowing... The worktable 110 is fixed. The threaded rod 203 drives the support plate 206 to move inward through the rotation of the support shaft 202. The limit rod 205 limits the movement of the support plate 206. The opening and closing shaft 208 drives the clamping support plate 209 to open and close, clamping the PCB printed circuit board to be cut. The clamping plate 211 adjusts the clamping force of the PCB printed circuit board through the connecting spring 210 to prevent the PCB printed circuit board from being damaged by excessive force during clamping. The chip tray 212 collects the chips generated during the cutting of the PCB printed circuit board.
