Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaner for removing solder slag from the tip of a soldering iron, and particularly to a soldering iron tip cleaner that prevents the temperature of the iron tip from decreasing when removing solder slag.

To remove solder slag from the tip of a conventional soldering iron, as shown in FIG. The solder slag and wire waste (hereinafter simply referred to as solder slag) were removed along with excess solder solidified by water by rotating it from side to side.

Cleaners using sponge pads remove solder slag manually, which takes a long time (3 to 5 seconds) to clean, resulting in a decrease in work efficiency and causing solder slag to scatter around the workbench, resulting in products being damaged. This was also a factor in reducing the reliability of the system.

FIG. 2 is a perspective view showing the configuration of the main parts of the soldering iron tip cleaner described in Japanese Patent Application Laid-Open No. 57-159264, which aims to shorten cleaning time and recover removed solder slag. When the first and second sponge rollers 6, 7 are pressed with a predetermined force into the housing 5 in which the soldering tip insertion hole 4 is formed, and the contact portions of the sponge rollers 6, 7 are It is supported by a bearing (not shown) so as to be located at a position opposite to the pre-insertion hole 4, and gears 6b and 7b attached to shafts 6a and 7a are in mesh with each other, and a reduction drive device 8 (hereinafter referred to as A small gear 8b attached to a rotating shaft 8a of a motor) rotates gears 6b and 7b.
The gear 6b rotates in the direction of the arrow (from the side facing the soldering iron tip insertion hole toward the contact part of the sponge roller) through the iron tip insertion hole, and the gear 6b has more teeth than the gear 7a, so the second sponge roller The sponge roller 7 is configured to rotate faster than the first sponge roller 6. 9 is a solder slag receiver, and 4 to 9 constitute an iron tip cleaner 10.

This soldering iron tip cleaner 10 is made by impregnating the first and second sponge rollers 6 and 7 with water, and inserting the soldering iron tip insertion hole 4 into the abutting portion of the rotating first and second sponge rollers 6 and 7. When you push in the soldering iron tip 3, it is the same as holding the soldering iron tip 3 from both sides with the cleaner sponge pads 2 shown in Figure 1 and pulling the soldering iron tip 3 in the direction of the arrow (Figure 1). The solder slag on the soldering iron tip 3 is removed by the action, and the removed solder slag is solidified by the moisture contained in the first and second sponge rollers 6 and 7, and the solder slag is The solder slag is peeled off from the surfaces of the first and second sponge rollers 6 and 7 due to a self-cleaning action based on the difference in rotational speed between the rollers 6 and 7, and accumulates in the solder slag receiver 9.

An iron tip cleaner using such a rotating sponge roller reduces the time required for cleaning to a fraction of that of the cleaner using a sponge pad shown in Fig. 1, and also reduces the amount of solder slag scattered on the workbench. There is no. However, since the sponge roller needs to be moistened, it has the disadvantage of lowering the temperature of the iron tip, and it is also necessary to replenish the sponge roller with an appropriate amount of moisture at least once a day. However, the problem was that this replenishment work was complicated.

The present invention has been made with the aim of solving these difficulties, and involves sliding a flexible solder slag scraping member formed into a linear or flaky shape on the circumferential surface of the soldering iron tip at a high speed. The solder slag attached to the soldering iron tip is scraped off, and the scraped solder slag is shaken off by centrifugal force, thereby preventing solder slag from adhering to the solder slag scraping member. The present invention provides an iron tip cleaner for cleaning.

Among the above components, the solder slag scraping member has heat resistance that will not melt or change in quality at the temperature of molten solder, and flexibility or flexibility that allows it to deform along the circumferential surface when it comes into contact with the soldering iron tip. Materials that have flexibility, hardness that does not abrade the iron tip, wear resistance, and physical properties that prevent molten solder from getting wet and adhering, such as cotton thread, vinylon thread, syuro fiber, and fine stainless steel wire. , PET film, etc. can be widely applied. Further, the mechanism for holding one end or both ends of the solder slag scraping member on the solder slag scraping drum may be any type of holding mechanism such as adhesion, binding, or hooking.

Examples of the present invention will be described below.

Fig. 3 is a perspective view showing the basic structure of the present invention, Fig. 4
Figures a and b are diagrams for explaining the action of the solder slag scraping drum, in which it is installed at an appropriate interval on the periphery of two discs 11 and 12 attached to the rotating shaft 8a of the motor 8. A plurality of kite strings 13 constituting the solder slag scraping member are fixed at both ends with appropriate slack, and the disks 11 and 12 and the plurality of kite strings 13 are used as a solder slag scraping drum 14 (hereinafter referred to as a drum). 14). When this drum 14 is rotated by the motor 8 at a high speed (for example, about 3000 rpm) in the direction of the arrow, the kite string 13 rotates with a bulge in the center due to centrifugal force, as shown in Figure 4 a and b. do. When the soldering iron is inserted through the soldering iron tip insertion hole 4 in this state, the soldering iron tip 3 comes into contact with the kite string 13 at the angle shown in FIG. The soldering iron tip 3 slides at a high speed from the base to the tip while deforming along the circumferential surface of the soldering iron tip 3, and the solder slag attached to the soldering iron tip 3 is removed from the kite string 13. It is removed by scraping it off from the side, leaving only the solder that thinly covers the surface of the soldering iron tip 3. The solder slag scraped off in this manner is blown away from the kite string 13 by centrifugal force, adheres to the wall surface of the housing 5, and is cooled and solidified. This cleaner requires the soldering iron to be rotated 180 degrees in order to clean the entire circumferential surface of the soldering iron tip 3.
The time for the kite string 13 to slide on the circumferential surface of the iron tip 3 is extremely short, and the force that is pressed against the iron tip 3 is only the centrifugal force due to the weight of the kite string itself, which is a small force. If a thick one is used, wear and tear due to wear will not be a practical problem.

Although it is easy to collect the solder slag that has scattered inside the housing 5 and adhered to the wall surface, it is possible to provide a solder slag receiving case surrounding the drum 14 to prevent the solder slag from scattering inside the housing. Needless to say.

FIGS. 5a and 5b are diagrams showing other configuration examples of the drum 14. In this example, retaining holes 15 having slits as shown in FIG. Kite string 1 with stoppers 16 fixed at intervals of
The kite string 13 is attached to the disc 1 by passing the kite string 13 through the slit and fitting the stopper 16 into the fastening hole 15 to fix it.
It is stretched diagonally between 1 and 12. In this way, the kite string 13 becomes a string with a smaller diameter in the center, and when the iron tip 3 comes into contact with the iron tip 3, the kite string 13 contacts the iron tip 3 obliquely and slides, improving the cleaning effect. do.

6a and 6b are diagrams showing another example of the structure of the drum 14. In this example, the disk is formed into a spider shape using a thin elastic metal plate or a synthetic resin plate, and this spider-shaped disk 17, 18 is fixedly supported by a hub 19, and a kite string 13 is stretched between the tips of each arm of spider-shaped discs 17 and 18. With this structure, when the iron tip 3 is brought into contact with the kite string 13, the arms of the discs 17 and 18 are bent as shown by broken lines and added to the kite string 13, as shown in FIG. 6b. The pressing force is eased, and when the kite string 13 comes off the soldering iron tip 3, the elasticity of the arm will flick off the solder slag, so even if the kite string 13 is thick, no solder slag will stick to it, resulting in a cleaning effect. As well as improving the durability, the product life can be extended.

In this embodiment, a highly wear-resistant material such as stainless steel wire or a thin chain can be used instead of the kite string, and the life of the solder slag scraping member or drum can be extended.

8a and 8b are diagrams showing other structural examples of the drum 14, in which a groove 21 formed in the hub 20 attached to the rotating shaft 8a has a heat-resistant and flexible groove 21 formed in the shape shown in FIG. 9a. A piece of film 23 (solder scum scraping member) having the same properties is inserted in the form of a folded film with its center part pressed by the mounting member 22, and clampers 24 are fitted from both ends to plant it radially on the hub 20. The film piece 23
For example, PET film is suitable.
The reason why the peripheral edge (end surface) is formed into a V-shape 25 is as follows.
When the soldering iron tip is brought into contact with the peripheral edge, the end face of the film piece is brought into contact over a wide range of the circumferential surface of the soldering iron tip 3.

In this example, the film piece 23 acts to scrape off solder scum at the end surface.

FIGS. 9b and 9c each show a modified example of the film piece 23, and FIG. 9b has a curved peripheral edge, a through hole 26, and a band-shaped portion 27 on the peripheral edge.
The outer edge 27a of the band-shaped portion 27 first contacts the iron tip, and the film piece bends so that the band-shaped portion 27 contacts the surface of the iron tip 3, and the inner edge 27b
This acts to scrape off solder slag, which improves the cleaning effect, and the provision of through holes 26 has the effect of reducing windage loss during rotation. 9th
Figure c shows a film piece 23 in which a plurality of cuts 28 extending in the radial direction are formed.The cuts 28 increase the flexibility, so a thick film can be applied.
Since the solder slag is scraped off at the end face of the cut 28, the life of the drum 14 can be extended and the cleaning effect can be improved.

FIGS. 10a and 10b show another example of the structure of the drum 14, in which a thick kite string or syringe fiber is folded in half using a mounting member 22 (for example, wire) in the mounting groove 21 formed in the hub 20. It was planted and maintained. When the drum 14 is rotated, the raised scraping member 29 comes into contact with the soldering iron tip in an upright manner, and the tip portion slides on the circumferential surface of the soldering iron tip to remove solder slag. This drum is easy to manufacture and has the effect of extending its life.

Any of the drums 14 shown in FIGS. 4 to 6, 8 to 10 can be applied to the cleaner of the embodiment shown in FIG. 3. However, as mentioned above, in order to clean the entire circumference of the soldering iron tip, the soldering iron must be rotated 180 degrees.
