Description

Technical Field

[0001] The utility model relates to the technical field of automatic inductance feeding, in particular to an automatic feeding device for inductance testing. Background Art

[0002] Inductors are one of the most common components in circuits, and they have the functions of filtering, oscillation, delay, and trapping. Inductors are divided into chip inductors and winding inductors. During the production process, each one often needs to be firmly fixed and moved to different workstations. During the production process, toroidal inductors need to be tested for conductivity to determine whether the performance of the inductor meets the requirements. During the test, the pins of the toroidal inductor are connected to the test circuit for performance testing. Therefore, when loading the material, the pins of the toroidal inductor need to accurately correspond to the test holes of the test circuit, resulting in the inability of conventional clamping loading to accurately match the pins of the inductor to the test circuit. Therefore, most of the inductor test loading is done manually, which has low loading efficiency and high labor costs. Utility Model Content
