[0002] PCB, or printed circuit board, is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuit boards to make electrical interconnections between the various components. The printed circuit board consists of an insulating base plate, connecting wires, and pads for assembling and welding electronic components. It has the dual functions of a conductive line and an insulating base plate.

[0003] The existing PCB production cannot realize full process automation. In the related technology, a conveyor belt is used to transport the PCB, but the friction of the belt conveyor belt is relatively large. At the same time, since the board surface of the PCB is relatively fragile, the conveyor belt is easy to scratch the board surface of the PCB during the conveying of the PCB by the conveyor belt, causing damage to the PCB during the conveying process. Based on this, the utility model proposes a PCB board conveying device for a circuit board production line. The device adopts chain conveying and cooperates with main rollers and auxiliary rollers for conveying. Compared with the problem of high friction of belt conveying, the conveying method of the utility model has less friction, and the auxiliary roller is a direct-drive force roller, which can increase the conveying speed of the PCB.
