BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soldering aid and a soldering method for stably soldering a component A and a component B in an accurate positional relationship.

[0002]

2. Description of the Related Art In a conventional soldering method, a part A is positioned and held on a jig base, and while a part B is held with a left hand, a solder between the part A and the part B is heated by a soldering iron having a right hand. After melting the components, the position and position of the component B are corrected with the left hand, and the solder is cooled and hardened, and the components A and B are cooled.
And was soldering. However, in this method, the part B
It is difficult to stably solder a large amount of components B at an accurate position because the components are manually soldered one by one. There was a problem.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a soldering assistant capable of performing stable soldering while maintaining good posture and position accuracy of the component B and automating. It is to provide a tool and a soldering method.

[0004]

According to the present invention, there is provided a soldering aid and a soldering method described in each claim as means for solving the above-mentioned problems. The soldering aid according to claim 1, wherein a plurality of upper jigs for removably positioning and holding an upper jig for positioning and holding a weight for holding a component B in a vertically movable manner on a transport jig base for holding a component A. By providing the upper jig positioning means, the component B can be accurately positioned on the component A, and when the solder is melted, the component B moves downward by its own weight, and further, the component B is moved by the weight. By being pressed against A, the solder spreads sufficiently between component A and component B, and accurate positioning and reliable soldering can be performed.

According to a second aspect of the present invention, the holding means for the component A is a component positioning pin and the upper jig positioning means is an upper jig positioning pin. Positioning and holding and removal can be performed easily. In the soldering aid according to the third aspect, the weight and the upper jig can be handled together without separating the weight and the upper jig by providing the weight with the removal prevention means for preventing the weight from being removed from the upper jig. Work can be done easily.

According to a fourth aspect of the present invention, the method of the first aspect of the present invention is an invention of the method, and has substantially the same operation and effect as those of the soldering aid of the first aspect. Similarly, the soldering method of the fifth aspect has the same effect as the soldering aid of the third aspect.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a soldering aid according to an embodiment of the present invention. FIG. 1 is an overall vertical sectional view of a soldering aid according to an embodiment of the present invention, and FIG. 2 is a partial detailed view thereof. The auxiliary soldering tool 1 of the present invention basically includes a transport jig base 2, an upper jig 3, and a weight 4.

[0008] A component positioning pin 22 as a component holding means for positioning and holding the component A11 to be soldered on the transport jig base 2 is fixedly provided on the transport jig base 2. . Further, a plurality of upper jig positioning pins 21 as upper jig positioning means for positioning and holding the upper jig 3 are fixedly provided on the transport jig base 2. A weight 4 for holding a component B12 to be soldered to the component A11 is provided on the upper jig 3 so as to be vertically movable in a hole provided in the upper jig 3. The part A1 is set by the upper jig positioning pin 21.
1 and is removably positioned and held thereon. A through hole is provided in the center of the weight 4, and the component B is held by passing through the hole. Although not necessarily required, the weight 4 is provided with a retaining ring 41 on an upper side surface thereof and a retaining claw 42 protruding from a lower side surface thereof. As the component holding means and the upper jig positioning means, anything other than a pin can be appropriately adopted. Also, as the means for preventing the weight 4 from being removed, a bar or a spring may be used instead of a ring and a claw. Means such as providing a protruding portion may be employed.

Next, the operation of the soldering aid 1 according to the embodiment of the present invention will be described. First, it is positioned on the transport jig base 2 by the component positioning pins 22,
The part A11 to be soldered is positioned and held. Next, the solder chip 13 is placed at a predetermined soldering position of the component A11. Further, the upper jig 3 is positioned on the component A11 on the transport jig base 2 with the upper jig positioning pin 21.
Hold the positioning.

On the other hand, in a component B supply device (not shown), a component B12 to be soldered to the component A
After the weight 4 has been assembled, the part B12 and the weight 4 are inserted into the hole of the upper jig 3 together, and the part B12 is inserted into the part A11.
Place on the overlying solder chip 13. Next, the soldering aid 1 in which the component A11 and the component B12 are set
Is heated in a furnace to melt the solder, and then cooled and soldered, and the component A11 to which the component B12 is soldered is removed from the soldering aid 1 to obtain the component A.
11 and the component B12 are soldered.

When the weight 4 is prevented from being separated from the upper jig 3 by the retaining means, the component B12 is attached to the weight 4 provided on the upper jig 3 in the component B supply device. After assembling, the upper jig 3 holding the component B12 is positioned by the upper jig positioning pin 21.
What is necessary is just to position and hold it on the transport jig base 2 and on the component A11.

As described above, in the soldering aid and the soldering method according to the present invention, the carrier jig base for holding the component A and the upper jig for positioning and holding the weight are accurately positioned and held by the positioning pins. Then, the weight for positioning and holding the component B is movably positioned and held by the upper jig, so that the component A and the component B are accurately positioned, and further, the component B is pressed down by the weight and the solder chip is pressed. When heated and melted, part B
Is accurately positioned at a predetermined position on the part A, and is pushed down by the weight of the weight, and the solder spreads between the parts, so that the posture and the positional accuracy of the part B are good and stable. This has a remarkable effect that soldering can be performed and automation can be performed. In addition, since the soldering aid has the above-described configuration, a plurality of parts B and a plurality of weights are assembled.
A plurality can be set on the upper jig at the same time.
