Description

Technical Field

[0001] This invention relates to the field of inductor production equipment technology, specifically to an automatic steel strip bundling machine. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but it has only one winding. A toroidal inductor is made by winding a coil around a magnetic toroid. A single wire wound from beginning to end is a differential-mode inductor, while two wires wound in parallel or separately on opposite sides are common-mode inductors. Currently, the process of bundling common-mode inductors with steel strips is mostly done manually. This is not only labor-intensive and inefficient, but also results in inconsistent product quality due to variations in manual operation. Summary of the Invention

The third gripper cylinder drives the third gripper to clamp the workpiece so that the gaps on both sides of the workpiece are expanded to allow the steel strip to pass through.

[0016] The steering mechanism includes a turntable and a second rotary cylinder. The first end of the steel strip is fixed on the turntable, and the second rotary cylinder drives the turntable to rotate, thereby turning the first end of the steel strip from the gap on one side of the workpiece to the gap on the other side of the workpiece.

This automatic steel strapping machine includes a steel strapping storage device 2, a steel strapping picking and feeding device 3, a steel strapping winding device 4, a steel strapping cutting device 5, a steel strapping pressing device 6, and a finished product conveying device 7, arranged sequentially. The steel strapping storage device 2 and the steel strapping picking and feeding device 3 achieve automated steel strapping feeding. The workpiece picking and placing transfer device 8 achieves automated transfer of workpieces between different workstations. The workpiece completes the steel strapping winding process on the steel strapping winding device 4, then is transferred to the steel strapping cutting device 5 for the steel strapping cutting process, then to the steel strapping pressing device 6 for the steel strapping pressing process, and finally is transferred to the finished product conveying device 7. The synchronous picking and placing transfer of the workpiece by the workpiece picking and placing transfer device 8 achieves automated production line operation, replacing the manual operation process in existing technologies. This effectively reduces labor intensity and has the advantages of high integration, good compatibility, high automation, and strong continuous working capability, effectively improving production efficiency and product quality.
