Description

Technical Field

[0001] The utility model relates to the technical field of inductor coil production equipment, in particular to a feeding mechanism of lead frame appearance detection equipment. Background Art

[0002] An inductor coil is an inductor that can be used at high frequencies. It features a simple structure, excellent performance, and a wide range of wire specifications, making it particularly suitable for inductor molding technology. This one-piece inductor is formed by die-casting a coil wound with round copper wire and iron powder using a special process. It features high current resistance and low impedance. Before forming, the inductor coil is spot-welded to a lead frame, then die-cast with insulating iron powder, and finally sheared and bent. In existing technology, the appearance of lead frames is typically not inspected. Appearance defects can compromise the weld quality between the coil and the lead frame. Therefore, designing an accurate and efficient inductor lead frame appearance inspection device is crucial. The inventors sought to address the problem of rapid, automatic loading of lead frames.

[0008] Compared with the prior art, the present invention has the following advantages: it can realize the automatic loading of wire racks. The loading support plate in the wire rack loading mechanism is used to place multiple discharge jigs, and multiple wire racks are stacked on each discharge jig. The loading and transferring unit can absorb and transfer the stacked wire racks in sequence to the double-row belt line. In the transfer mode, the stacked wire racks are lifted up by the jacking unit, which makes it convenient for the loading and transferring unit to take out the materials. The discharge jig is inserted into the slot. This setting can well fix the discharge jig. When the jacking unit is working, the discharge jig can be stable, and the plug-in connection makes it convenient to remove the discharge jig.
