[0032] In the present invention, workers place the motor stator and PCB board in a jig at the feed end of a conveyor, with the PCB board located at the upper end of the motor stator. After the conveyor steps the jig to the set position on the lower side of the hot riveting assembly, the jig is first positioned using a positioning assembly so that the hot riveting assembly can be precisely aligned with the motor stator and PCB board to be processed to ensure a hot-melt effect. Subsequently, the PCB board is pressed down and hot-melted onto the motor stator through the hot riveting assembly to achieve a hot-riveted connection between the PCB board and the motor stator. The finished parts that have completed hot riveting are discharged from the discharge end of the conveyor under the transfer of the conveyor, and the induction probe always monitors the workpieces on the conveyor to obtain data such as the number of workpieces and the position of the workpieces.

In addition, the vertical movement distance of the hot riveting gun can be changed through the servo linear module and adjusted according to different workpiece heights, making the hot riveting mechanism suitable for multiple identical but different height products.
