The marking device

A marking device comprises a supporting part, a conveying part, a marking mechanism, a feeding mechanism, a discharging mechanism, a driving mechanism and a positioning jig. The conveying part is arranged on the supporting part and used for conveying a workpiece, the marking mechanism is arranged on one side of the conveying part, the feeding mechanism and the discharging mechanism each comprise a driving assembly arranged on the supporting part and an attracting assembly arranged on the corresponding driving assembly, the driving mechanism is arranged on one side of the marking mechanism, and the positioning jig is arranged on the driving mechanism; the driving mechanism drives the positioning jig to the feeding mechanism, the driving assembly of the feeding mechanism drives the attracting assembly of the feeding mechanism to attract the workpiece on the conveying part to the positioning jig, the driving mechanism drives the positioning jig and the workpiece to the marking mechanism for marking, and drives the positioning jig and the workpiece to the discharging mechanism after marking is finished, and the driving assembly of the discharging mechanism drives the attracting assembly of the discharging mechanism to attract the workpiece on the positioning jig to the conveying part. The marking device is high in work-piece marking efficiency.
