Conventionally, the magnetic core for a watch coil and its windings have been insulated by wrapping them with tape 2 as shown in FIG. 1, or by coating them with electrostatic paint 3 as shown in FIG. However, tape winding has problems in that wrinkles occur when the magnetic core is curved, and the folded portion of the tape peels off, as shown in FIG. In addition, in the case of electrostatic painting, the thickness of the paint film is not uniform as shown in Figure 4, and the paint is thinner in the corners, and as shown in Figure 5, the paint is applied to areas other than necessary. There was also the problem of

The present invention relates to a method for coating a magnetic core for a coil of a watch with an insulating material, in which an insulating material injected into a plate with a recessed portion on the surface is printed and coated on the surface of a magnetic core for a coil using a soft pad to form an insulating film. It is characterized by

る。 First, as shown in figure a, the insulating material 5 is injected into the plate 4 which has a recessed part so that it goes around the plane and side surface of the magnetic core.Then, as shown in figure b, the insulating material 5 is neatly injected into the recessed part in the plate 4 using a spatula 6. do. Then, as shown in Figure C, the insulating material 5 injected into the recessed portion of the plate 4 is attached to the tip of the soft pad 7. The insulating material 5 attached to the tip of the soft pad 7 is pressed against the magnetic core 1 on the guide plate 8, as shown in Figure d, to form an insulating coating film on the plane and side surfaces of the magnetic core 1. In this embodiment, the insulating coating film was formed on one side of the magnetic core, but the insulating coating film could be formed even faster if both sides were printed and coated at once.

As described above, according to the present invention, an insulating coating film can be formed at a predetermined position and in a predetermined shape due to the shape of the recess provided in the plate, so that it is possible to form the insulating coating film even on a curved magnetic core. In addition, the thickness of the insulating coating can be adjusted simply by changing the depth of the recesses provided in the plate, making it possible to form a thin insulating coating that is less than half the thickness of conventional tape wrapping or electrostatic coating. I can do it.
