Abstract

The application relates to the technical field of hot riveting of plastic products, in particular to a laser hot riveting device which comprises a rack, a die, a Y-direction driving assembly, a laser heating assembly, a riveting assembly and a temperature acquisition assembly. The Y-direction driving assembly drives the die to switch positions, the laser heating assembly heats a workpiece, and the riveting assembly drives the upper die to hot rivet the workpiece. The laser hot riveting device provided by the application only needs to replace the die when changing product models, and the heating clamp does not need to be redesigned, thereby reducing development cost and shortening the development cycle. The laser heating assembly realizes non-contact heating and softening of plastic riveting columns. The temperature detection precision is improved through infrared temperature measurement.
