Traditionally, the dimension and surface defect are inspected by human eyes. However, the uncertainty percentage will be here when observing defects’ images through human eyes. In an optical sorting machine, there is an image system inside and the defects are easily captured by the industrial cameras and then be zoom clear. In inductance quality inspection , we faced with the problems of cracks, missing material, broken edge, crack,chipping ,sticking, etc. A vision system that designed to solve these problems are in need in massive production process.

In Inductor’s world, it introduces the manufacturing process of inductors in two types.
-
Wire-winding type
-
1.Core manufacturing – After the process of creating the fine particles, molding, and firing, electrodes are formed on the manufactured core (magnetic core).
-
2.Wire-winding – A wire is wound around the core, and then terminals of the wire are connected to the core.
-
3.Frame processing – The wire-wound core is sandwiched by the frame.
-
4.Molding – Resin is poured over the coil sandwiched by the frame.
|
-
5.Terminal treatment – The resin-covered coil is separated, and the frame is bent to form electrodes.
-
Multilayer type
-
Paste forming – Ferrite powder and resin are mixed to form ferrite paste.
-
Sheet forming and printing – The ferrite paste is flattened into a sheet form, and electrodes are printed on it.
-
Multilayer process – Electrode-printed ferrite sheets are stacked in layers and pressed.
-
Cutting and firing – The stacked sheets are cut with a blade into the prescribed size, and perfectly fired in a furnace.
-
Electrode coating and plating – Both ends of the fired coil are dipped in electrode paste, and then baked. Next, the entire body of the coil is dipped in plating solution.
