The invention relates to a laser heating rivetless riveting device in the technical field of automobile manufacturing. The laser heating rivetless riveting device comprises a compound punch pin, a compound blank holder, a compound lower die and a laser control system, wherein, the compound punch pin is sheathed with the compound blank holder, and the compound punch pin, a workpiece and the lower die are arranged coaxially from top to bottom; hollow circular holes are formed at the center parts of the compound punch pin and the compound lower die; optical fiber tubes and concave lenses are arranged in the hollow circular holes; grooves are formed in the surfaces of the compound blank holder and the compound lower die in contact with a panel veneer, and are used for laying out thermistors that are lead wires; and the lead wires are connected with a laser control system. The laser heating rivetless riveting device heats a forming area of riveting material through laser before riveting forming so as to improve the forming performance of material, prevents fragile material from being easy to crack and fracture during the riveting process, reduces the plastic deformation resistance of material at the same time, enables the panel veneer to deform fully during the forming process, is easy to get a rivet joint with better quality, and reduces the requirements on riveting force and rigidity of riveting equipment at the same time along with the reduction of plastic deformation resistance of material.
