Description

Technical Field

[0001] The utility model belongs to the field of inductor coil production equipment, in particular to an automatic wiring machine. Background Art

[0002] With the development of industrial control, the use of inductor components has gradually increased. Inductor components are components that can convert electrical energy into magnetic energy and store it. The inductor component structure is mainly composed of a base, a magnetic ring, a coil and other components. The coil assembly production mainly involves assembling the coil on the magnetic ring of the base to complete the coil assembly. After the coil is assembled on the magnetic ring, the pins of the coil are bent in various directions and irregularly distributed outside the base. Therefore, the pins of the coil need to be positioned, adjusted or bent before they can be overlapped and contacted with the wiring terminals on the base. From the beginning, the wiring process of the inductor coil pins and the wiring terminals is completed, so as to prepare for the next step of welding the coil pins and the wiring terminals on the base. The existing wiring assembly of the inductor coil pins and the wiring terminals relies on manual terminal wiring operations, which is inefficient and cannot meet the growing demand for inductor coil processing. Manual assembly can easily cause the inductor coil pins to be inaccurately wired and not in contact with the wiring terminals, often resulting in cold welding or excessive soldering during welding. Manual wiring will lead to poor quality and performance of the inductor coil, and the labor production cost remains high. For this reason, it is necessary to design an automatic wiring machine to meet the needs of coil wiring assembly and improve productivity. Utility Model Content
