Description

Technical Field

[0001] This utility model relates to the field of automotive processing equipment, and in particular to an integrated riveting and marking machine. Background Technology

[0002] Currently, in the automotive industry, aluminum profiles are typically fixed using rivet nuts during parts assembly. Marking is then required on the fixed components for tracking and identification. Riveting and marking are two separate processes, each requiring different riveting and marking equipment. This involves multiple steps and repeated clamping and positioning of parts, increasing workload and wasting time. Furthermore, inaccurate positioning during component fixing can affect product manufacturing precision and consistency. Repeated operation by operators can even lead to batch quality incidents, causing serious losses to the company. Existing technology CN210967491 U is an integrated laser marking rivet nut detection device, used only for detecting rivet nuts and marking, and is not suitable for automotive assembly operations. Therefore, an integrated riveting and marking machine for aluminum profiles, combining riveting and marking equipment to process the same aluminum profile simultaneously in both processes, reducing inter-process turnover, saving manpower and time, is needed.

After pressing the start button, the longitudinal clamping part 2-2-2 of the clamping device 2-2 clamps the riveted workpiece. The operator holds the riveting gun 4 to perform the riveting operation. After completing the riveting operation in one direction, the operator operates the flip controller 2-3 to flip the fixed base 2-1 90°. The operator holds the riveting gun 4 through the riveting through hole 2-1-2 at the bottom of the fixed base 2-1 to perform the riveting operation in the other direction. After the riveting operation is completed, the operator manually resets the fixed base 2-1, which triggers the control system 5 to start the marking operation. The transverse clamping part 2-2-1 moves horizontally to the riveted workpiece, and the protective cover 3-1-2 moves downward to cover the riveted workpiece. The laser generator 3-1-1 generates a laser beam to mark the riveted workpiece. After the marking operation is completed, the clamping device 2-2 automatically resets, and the operator removes the riveted workpiece.
