Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple method for bonding resin-plated parts, which enables strong bonding of resin-plated parts to parts to be bonded.

When adhering conventionally resin-plated parts such as batchers and knobs to plastic cabinets and plastic dials, they can be attached using metal ring springs, bonded together by heat welding, or bonded using adhesive. Attachment methods such as gluing were used.

Conventional examples are shown in FIGS. 1, 2, and 3.

In the figure, 1 is a part to be glued such as a plastic cabinet or a plastic dial, 2 is a part to be glued such as a batcher or a knob, 3 is a mounting part, 4 is a mounting hole, 11
Shown is a metal ring spring.

FIG. 1 shows a case in which a mounting portion 3 is inserted into a mounting hole 4 of a plastic cabinet 1, a metal ring spring 11 is inserted into the mounting portion 3, and a knob 2 is attached to the plastic cabinet 1 or the like.

FIG. 2 shows a case where the mounting portion 3 is heated and thermally welded.

Figure 3 shows the case using adhesive.

The attachment part 3 of the adhesive component 2 is inserted into the attachment hole 4 of the component provided in the plastic cabinet 1, and the adhesive component 2 is adhesively fixed to the component 1 to be adhered by, for example, being bonded from the back side with an adhesive 5.

In this case, if the attachment part 3 of the adhesive article 2 is resin-plated or the attachment part of the adhered part 1 is resin-plated, the adhesive will not be well bonded and will easily come off.

Therefore, when performing resin plating to prevent these defects, for example, masking the bonding area and applying resin plating to prevent resin plating from being applied to the bonding area.
Adhesive attachment processing was performed at this adhesive location.

However, the resin plating method using masking is time-consuming and troublesome.

This invention eliminates the above-mentioned drawbacks, and uses a simple process that does not require troublesome means such as masking to prevent resin plating.
The object of the present invention is to provide a method for bonding resin-plated parts, which is characterized by providing a bonding location and performing strong bonding at this location.

This invention will be explained based on the drawings.

FIG. 4 is a perspective view of a bonded part used in the resin-plated part bonding method of the present invention, and FIGS. 5 to 8 sequentially show the steps of the present invention in longitudinal cross section.

FIGS. 9 and 10 are longitudinal sectional views showing the adhesion process of another embodiment of the present invention.

The same reference numerals as in FIGS. 1 to 3 indicate the same parts.

Reference numeral 6 represents a bonding part such as a batcher, 7 a convex dowel, 8 a resin plating layer, 9 a cutout portion, 10 a bonding location in the bonded part 1 such as a plastic cabinet, and 12 an adhesive.

In this process, the convex dowel 7 has a diameter that can secure the area necessary for bonding during the bonding process.

Next, this invention will be explained in detail.

As shown in FIG. 4, a convex dowel 7 having the same diameter is provided at the bonding point of the bonded part 6 such as a batcher, and as shown in FIG. 3, a resin plating 8 is applied to the entire surface of the bonded part 6. .

In this case, the convex dowel 7 does not need to be plated with resin, but may be plated with resin as shown.

Next, as shown in FIG. 6, the convex dowel 7 of the bonded part 6 is cut out from the base, the notched part 9 is made smooth, and a cut is made at the bonding point 10 of the bonded part 1 as shown in FIG. If the notches 9 are overlapped and ultrasonic bonding is performed in the direction of the white arrow, since the notches 9 are not plated with resin, strong adhesion will be achieved at the bonding location 10 as shown in FIG.

As another embodiment, instead of the ultrasonic bonding, as shown in FIG. 9, adhesive 11 is applied to the notch 9 of the bonded component 6, and the bonded component 6 is overlaid on the bonding location 10 of the bonded component 1. Then, since the notch portion 9 is not plated with resin, strong adhesion can be achieved.

This invention is based on the above-mentioned process, and the bonding parts of resin-plated parts are not resin-plated, and the conventional masking process is not required, so the process can be simplified, strong and reliable adhesion can be obtained, and the cost can be reduced. It produces effects such as being able to down.
