The present invention relates to a soldering apparatus, a soldering method using a solder wire holder, and a method of disassembling the solder wire holder.

Conventionally, as solder used for joining parts of electronic devices and the like, a type called wire solder formed into an elongated linear shape is often used. Such wire solder is generally used in a state of being wound around a plastic tubular body (bobbin) in consideration of handling at the time of soldering. Then, after the solder wire is used up, the above-mentioned bobbins are disposed of as plastic waste, and there is a problem that the environment is polluted by dumping these into the ocean.

Therefore, a tubular core member around which the solder wire coil is wound and two flange portions provided at both ends of the core member are provided, and at least one flange portion is detachably screwed to the core member to solder the solder wire. A reusable solder wire fixture configured so that the coil can be attached and detached has been proposed (see, for example, Patent Document 1).

Further, the present inventors have a first shape-retaining member having a tubular outer core body inserted into the center hole of the solder wire coil and a first flange portion covering one end surface of the solder wire coil, and an inner core body. A second shape-retaining member having an inner core body inserted into the solder wire and a second flange portion covering the other end surface of the solder wire coil is provided, and the outer core body has a plurality of slits extending in the axial direction from the tip portion thereof. At the same time, a ridge extending in the circumferential direction is formed on the inner peripheral surface of the outer core body, and an engaging groove with which the ridge is engaged is formed on the outer peripheral surface of the inner core body.

Therefore, before the solder wire coil H is used up, the work of releasing the coupling state between the first shape-retaining member 1 and the second shape-retaining member 2 and replacing the solder wire coil H in use with another one is performed. It can be done easily.

In the first embodiment described above, the thickness of the locking claw 15 is increased by providing the recessed portion 16 having the outer peripheral surface recessed in the mounting portion of the locking claw 15 provided on the outer core body 11. The outer core body 11 is formed to be thinner than the plate thickness of the main body portion. Therefore, as shown in FIG. 1, a gap corresponding to the recessed amount of the recessed portion 16 is formed between the outer peripheral surface of the locking claw 15 and the inner peripheral surface of the solder wire coil H, and the gap is formed. The presence allows the locking claw 15 to swing and displace.

Moreover, even when the outer core body 11 of the first shape-retaining member 1 is made of a material having a predetermined rigidity, as shown in FIG. 30, the protrusion 33 of the fastening release jig 3 is formed. When the locking protrusion 14 is released from the locking protrusion 14 by inserting it into the communication groove 26 of the shape-retaining member 2, the locking claw 15 is easily oscillated and displaced to stop the shape. The anchored state of the locking protrusion 14 with respect to the groove 23 can be reliably released.

In the first embodiment described above, an example will be described in which the recessed portion 16 in which the outer peripheral surface of the installation portion of the locking claw 15 is recessed is formed over the entire length from the tip end portion to the base end portion of the outer core body 11. However, it is not always necessary to form the recessed portion 16 over the entire length from the tip end portion to the base end portion of the outer core body 11, and the recessed portion 16 of the portion located below the locking claw 15 is omitted. May be good. However, in this case, stress concentration is generated at the base end portion of the locking claw 15, and the base end portion of the locking claw 15 is easily damaged. Therefore, as described above, from the tip end portion of the outer core body 11. It is desirable to form the recessed portion 16 over the entire length up to the base end portion.

Further, the first embodiment described above, wherein the locking protrusion 14 is formed on the inner peripheral surface of the tip portion 11 of the outer core body, and the fastening groove 23 is formed on the outer peripheral surface of the base end portion of the inner core body 21. Instead, for example, a locking protrusion 14 is formed on the inner peripheral surface of the outer core body 11 located at the axial intermediate portion, and a fastening groove is formed on the outer peripheral surface of the inner core body 21 located at the axial intermediate portion. It is also possible to form 23.

However, in the above configuration, since the locking protrusion 14 and the fastening groove 23 are provided at positions away from the second flange portion 22, the locking protrusion 14 and the fastening groove 23 are stopped via the communication groove 26 formed in the second flange portion 22. The operation of releasing the anchored state of the locking protrusion 14 with respect to the flange 23 cannot be easily performed. Therefore, as shown in the first embodiment described above, the communication formed in the second flange portion 22 is formed by forming the locking protrusion 14 and the fastening groove 23 at a position close to the second flange portion 22. It is desirable that the structure is such that the operation of releasing the anchored state of the locking protrusion 14 with respect to the anchoring groove 23 via the groove 26 can be easily performed.

Further, in the first embodiment described above, the pair of positioning portions 17 with which the engaging portions 24 of the inner core body 21 are engaged are formed so as to extend from the tip end portion of the outer core body 11 toward the base end portion side thereof. The outer core body 11 is divided into a pair of left and right divided pieces 18 having a semicircular cross-sectional shape by a positioning portion 17 formed of the slits. Therefore, even when the inner diameter of the solder wire coil H, that is, the diameter of the center hole H11 is smaller than the outer diameter D1 of the outer core body 11 due to a manufacturing error, the outer core body is inserted into the center hole H11 of the solder wire coil H. When the 11 is inserted, each of the divided pieces 18 is oscillated and displaced to reduce the diameter of the outer core body 11, so that there is an advantage that the insertion operation of the outer core body 11 can be smoothly performed.

Further, in the first embodiment described above, the base end portion of the positioning portion 17 formed on the outer core body 11 is provided with the connecting portion 17a formed to be thinner than the main body portion of the outer core body 11. Since the side wall surfaces of the divided pieces 18 facing each other are connected to each other by the connecting portion 17a, the base end portion of the outer core body 11 is reinforced by the connecting portion 17a to sufficiently secure the strength of the outer core body 11. can do.
