DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an intermediate assembly device of a controller used for electronic control of fuel injection of an automobile engine, and more specifically, a bottomless type controller. The present invention relates to a soldering forming jig device in which a plurality of capacitors are passed through a shield case and attached by soldering, and an electric wire (lead wire) of the capacitor after the soldering is bent to have a predetermined shape.

(Prior Art) In order to obtain an intermediate product of a controller for controlling electrical components of an engine, a jig device for soldering and forming a feedthrough capacitor has conventionally been manually operated to obtain an intended intermediate product. The method using the conventional apparatus will be described below in the order of steps with reference to FIG. As shown in FIG. 3 (a), four side walls of a flat rectangular parallelepiped shield case (workpiece) having upper and lower surfaces open, that is, without a bottom plate, are passed through the shield case (workpiece 4) to determine four capacitors 2 (how many It may be pointed out, and these are heated by hand with an air heater and attached by soldering. After this soldering, the electric wires 3 serving as lead wires are projected on both sides of the capacitor 2,
The proposition is to bend the long, inner wire at a right angle to the top. Therefore, first, as shown in (b), a jig (B) 5 having the same number of grooves 4 into which the electric wires 3 are inserted is prepared. On both sides of the lower portion of the jig (B) 5, there are guide plates 6 that horizontally project. Next, as shown in (C), a jig (A) 8 having a plurality of triangular thin plates 7 for bending the electric wire 3 is prepared. Then, as shown in (d), the jig (B) 5 is inserted along the left inner wall of the work 1 of (a), the electric wire 3 is inserted into the groove 4, and the jig (A) 8 is inserted along the right inner wall. . Next, as shown in (e), the jig (A) 8 is horizontally moved by hand as shown by an arrow X, and then the tip 7a of the thin plate 7 is moved.
Rotate around. With this arrangement, the electric wire 3 of the capacitor 2 is bent at an angle α of about 60 ° as shown in (f) by the horizontal movement, and at an angle β of about 90 ° at the next rotation as shown in (g). Will be things. In this way,
Conventionally, the through-forming capacitor was soldered by hand.

(Problems to be solved by the invention) However, since such a conventional one is manually soldered and molded as described above,
The heater heats the hand holding the condenser. Also,
At the time of soldering by a person (worker), the capacitor 2 and the electric wire 3 are bent and attached as shown in FIG. 4, or the forming angle is not constant as shown in FIG. 5, which is bad for the subsequent assembling work. There was a problem that it would have an influence and that it would take a lot of man-hours to correct it. The present invention provides a soldering forming device for a feed-through capacitor that mechanizes the soldering and forming work automatically and does not heat the hand, does not adversely affect the subsequent assembling work, and does not require man-hours. The purpose is to solve the above problems.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention is a state in which one side wall of a vertical three-dimensional shield case (work) whose upper and lower surfaces are open stands upside down. Attached to the work base and capable of holding a plurality of capacitors with electric wires facing upward on the bottom surface, and a shield by heating the capacitors from one open side of the shield case. A heater device to be soldered to a case, a jig A having a plurality of triangular thin plates for bending the electric wires of the capacitor, and a plurality of grooves for holding the electric wires when the jig A is bent by the thin plate entering. A jig B having
A base for fixing the jig B, a first cylinder that operates so as to combine the work base and the jig B by entering the shield case after completion of soldering from the other side opened, and the work. It is provided with a second cylinder that operates so that the jig A is moved closer to the combination of the base and the jig B and then rotated.

(Operation) The operator sets the work upright on the work base, puts multiple capacitors on the bottom of this work, presses the operation button, and the air heater of another place approaches first from the open surface of one side. Heat and solder the capacitors. At this time, my hands are separated from the capacitor so it does not get hot. Next, by the first cylinder, the work base enters the jig (B) fixed to the base from the open surface on the other side of the work and is combined. Then, by the second cylinder, the jig (A) comes close to this combination, first makes an intermediate bend, and then rotates and bends at a right angle. The mechanical work of such a jig makes the bending angle constant.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. First, the configuration will be described. Work 1, jig (B) 5
Although the jig (A) 8 is the same as the conventional one, it is an important point in this embodiment that they are arranged so as to be related to each other. Therefore, FIG. 3 of the conventional drawing will be referred to as necessary.

The base 10 is fixed to the floor, and the bracket 11 is attached to the base 10.
The jig (B) 5 is fixed by. A work 1 in the shape of a rectangular parallelepiped whose upper and lower surfaces are opened is attached to a work base 12 in a vertically installed state with one surface of a side wall as a bottom, and is attached and held by a work retainer 13.

Then, a capacitor 2 having an electric wire (lead wire) 3
4 are manually placed on the side surface which will be the bottom surface of the case 1. At this time, since the case 1 is vertically placed, the capacitor 3 is vertical, and the state is maintained even if the worker releases his hand. In this state, separately installed super air heater
24 is approached, and heated air is sent from the outer open surface of the case 1 to the portion of the capacitor 2, which is heated and soldered. The work base 12 can be moved by a moving cylinder 14 of the base 1 with respect to the base 10 via rails 25. In FIG. 1, this work base 12 is on the right side and shows the state before the jig (B) 5 and the work 1 are combined. As can be seen from FIG. 2, the jig (A) 8 is connected to the shaft 16a of the second forming cylinder 16 via the bracket 15 by the pin 17. The forming cylinder 16 has a lower end supported by a bracket 21 on the base 10 via a pin 19 so that the pin 19 serves as a tilt fulcrum.
Moreover, the upper side is supported by the bracket 22 so as to be tiltable. By attaching one end of the spring 23 to the upper end of the cylinder 16, the upper side of the cylinder 16 is always pulled in the direction of the table 10 to which the other end of the spring 23 is attached.

Next, the operation of the above embodiment will be described. Work base 12
Then, the work 1 is set upright, and then the capacitor 2 is placed on the bottom surface and the hand is released. Then, when a button on the control panel (not shown) is pressed, the separately placed air heater 24 approaches and the heated air is released from the outside of the work 1 into the condenser 2
Spray on. When the heating is completed, the heater 24 moves out.

At this time, since it is not necessary for the worker to hold the capacitor 2 by hand, the heater 24 will not heat the hand by releasing the hand.

When the cooling and soldering are completed, the movement cylinder 14 is actuated to move the work base 12 and the work 1.
Moves to the left and the jig (B) 5 and the work 1 are combined,
Movement stops.

In this case, the work 1 is assembled by wrapping not only the jig (B) 5 but also the jig (A) 8 by shifting the work 1 to the left inside. After this moving step, the forming cylinder 16 operates and the shaft 16a retracts. The bracket 15 connected to the shaft 16a by the pin 17, and thus the jig (A) 8
Comes close to the jig (B) 5 and the work 1, and the thin plate 7 is placed in the groove 4.
Enters. The state where the approach is completed is the same as the intermediate bending state shown in FIG. 3 (f). Forming cylinder 16
When the shaft 16a is further retracted by the subsequent operation of, the tip 7a of the thin plate 7 of the jig (A) 8 is stopped from moving by the groove 4 of the jig (B) 5 (the tip of FIG. 3C). The jig (A) 8 rotates about this tip as a fulcrum. Therefore, the bracket 15 of the jig (A) 8 also rotates and becomes in the state of the chain line (see FIG. 2). The movement of such a jig (8) is
As shown by an arrow Y in FIG. 2, it is the same as the conventional one, that is, the arrow X in FIG. It can be said to be constant.

[Effects of the Invention] As described above, according to the present invention, the hands of the workers do not become hot during the soldering work, and the variation in the forming angle due to the difference in the workers is eliminated, This has the effect of not adversely affecting the work.
