[0020] The drive device can be a motor that drives a sprocket to rotate, and the sprocket drives a chain to drive a conveyor roller to rotate. During the rotation of the conveyor roller, the circuit board is moved from the inlet end to the outlet end.

[0021] In this embodiment, roller 4 is used to support the circuit board and prevent it from sagging and jamming. Preferably, along the circuit board conveying direction, the distance between rollers on two adjacent conveying rollers is 30-60mm, and the distance between two adjacent rollers on the same conveying roller is 40-80mm. By optimizing the roller spacing and increasing their density, the sagging of thin circuit boards can be effectively prevented, avoiding jamming during conveying.

[0022] In this embodiment, roller 4 is a soft roller, such as PU material, which can reduce the frictional damage of the roller material to the circuit board.

[0023] In this embodiment, the inlet end of the conveying device is equipped with a pneumatic ejector pin 5, which is used to separate stacked boards. When a circuit board is conveyed to the inlet end, the pneumatic ejector pin 5 extends and acts on the circuit board. After the pushing operation is completed, the pneumatic ejector pin retracts.
