Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a method of manufacturing an electronic component having a resin member, which is highly productive.

(Prior Art) Conventionally, electronic components having resin members, such as variable resistors having knobs made of resin, have been manufactured sequentially in the direction of arrow X by a method as shown in FIG.

In Fig. 4, reference numeral 1 denotes an insulating substrate, on which an arc-shaped resistor 1a is formed, a current collecting electrode 1b is formed in a hole provided in the center, and is electrically connected to one end of the resistor 1a. lead terminal 2a, resistor 1
a lead terminal 2b electrically connected to the other end of a;
Lead terminal 2 electrically connected to current collecting electrode 1b
c are buried respectively.

Reference numeral 3 denotes a slider, which has a contact 3a that slides on the resistor 1a, a projection 3b for positioning with a knob 5, which will be described later, and a plurality of claws 3c. It is rotatably mounted on the current collecting electrode 1b by being locked in the hole.

Each of the plurality of insulating substrates 1 has a lead terminal 2.
a and 2b, and a hoop terminal 4b connected to the lead terminal 2c, and the plurality of sliders 3 are each supplied by the hoop terminal 4c.

Reference numeral 5 designates a knob made of resin, and has a driver groove 5a formed on its upper surface, and, as shown in FIG. 5, a shaft 5b and a recess 5c. By fitting the shaft 5b into the hole of the current collecting electrode 1b, the shaft 5b rotates together with the slider 3. Since the knobs 5 are made of resin, it is necessary to supply one each.

These variable resistors have a slider 3 on an insulating substrate 1.
After attaching the knob 5, connect the lead terminals 2a and 2b from the hoop terminal 4a, the lead terminal 2c from the hoop terminal 4b, and the slider 3 from the hoop terminal 4c.
are respectively cut.

(Problems to be Solved by the Invention) However, the above-described conventional method for manufacturing electronic components having resin members has the following problems. In other words, the insulating substrate 1 and the slider 3
Even if the other parts such as 4a, 4b, and 4c are supplied using the hoop terminals 4a, 4b, and 4c, each knob 5, which is a resin member, must be supplied one by one, making it impossible to assemble through consistent automation, which reduces productivity. There was a problem that it was bad.

Furthermore, if the resin member is required to have directionality, for example, the protrusion 3b of the slider 3 may be placed in the recess 5c of the knob 5.
When the resin members have to be fitted together, the resin members must be aligned one by one in a fixed direction, which further reduces productivity.

(Means for Solving the Problems) The present invention has been made to solve the problems of the above-mentioned conventional techniques. As a means for manufacturing electronic components having a resin member according to the present invention, at least a part of the periphery of the hole is sandwiched between the hole portion of a tape material in which a plurality of holes are formed at regular intervals. The resin members were molded using a mold, each resin member was bonded to another member of the electronic component while the resin member was attached to the tape material, and then the tape material was removed.

(Description of Embodiment) An embodiment of the present invention will be described below with reference to the drawings, taking a variable resistor as an example. The same parts as those shown in the prior art section are given the same numbers,
The explanation will be omitted.

First, as shown in FIGS. 1A and 1B, the tape material 6 is moved in the direction of arrow Y to the hole 6a portion of the tape material 6 in which a plurality of approximately circular holes 6a are formed at regular intervals. molds 7a and 7b while
As a result, the knob 5, which is a resin member, is sequentially formed so as to sandwich at least a portion of the periphery of the hole 6a. As the tape material 6, paper tape, plastic tape, etc. can be used.

Next, as shown in FIG. 2, the knob 5 is supplied using the tape material 6, the shaft 5b of the knob 5 is caulked into the hole of the current collecting electrode 1b, and then the tape material 6 is pulled upward. Remove the tape material 6 from the knob 5 one by one. After the tape material 6 is removed, the groove 5d that held the periphery of the hole 6a remains on the knob 5. This process consists of tape material 6, hoop terminal 4
This is performed sequentially while moving a, 4b and 4c in the direction of arrow Z.

Finally, as in the conventional case, the lead terminals 2a and 2b are cut from the hoop terminal 4a, the lead terminal 2c is cut from the hoop terminal 4b, and the slider 3 is cut from the hoop terminal 4c.

The above is an example of the method for manufacturing an electronic component having a resin member according to the present invention, and it goes without saying that the design can be changed within the scope of the invention. For example, the tape material 6 may cause the knob 5 to
After supplying and caulking the shaft 5b of the knob 5 into the hole of the current collecting electrode 1b, without removing the tape material 6 from the knob 5, connect the lead terminals 2a and 2b from the hoop terminal 4a, the lead terminal 2c from the hoop terminal 4b, The sliders 3 may be cut from the hoop terminals 4c, and the tape material 6 may be used as a holding material for the completed variable resistor group.

Further, the shape of the hole 6a formed in the tape material 6 is arbitrary, and is not limited to a substantially circular shape as in the above embodiment. Furthermore, as shown in FIG. 3, radial cuts 6b are provided from the hole 6a,
The knob 5 may be easily removed from the tape material 6.

(Effects of the Invention) As is clear from the above explanation, according to the method for manufacturing electronic components having resin members of the present invention, since the resin members can be supplied by tape material, consistent automatic assembly is possible. is possible and highly productive. Further, even if the resin members are required to have directionality, there is no need to align the resin members one by one in a fixed direction, further increasing productivity.
