A rotary shaft 34 whose f end side is connected to a motor etc. not shown and rotates by the rotational force of the motor etc., and a rotary shaft 34 which is attached to the tip of this rotary shaft 34 and is held between the chuck 11 of the second arm 1b and the bottle 1j. Furthermore, the chuck 35 rotates a predetermined number of times while holding the overlapping portions of both ends of the loop-shaped wire 4 to form a twisted portion 4a in the loop-shaped wire 4.

The flux application means 9 is a twisted part 4a of the loop-shaped wire 4.
In order to ensure soldering, flux is applied to the twisted portion 4a of the loop-shaped wire 4 held by the third arm 1C, and in this embodiment, flux is applied from the flux tank (circuit). A spouting member 36 and the like having a nozzle for jetting flux toward the torsion 81!4a is provided.

The take-out hand g214 is for removing the loop-shaped wire 4 held by the chuck 11 while hooking the loop part to the bottle 1j of the seventh arm 1g and taking it out from the seventh arm 1g side. . The take-out means 14 of this embodiment is designed so that a solder+J strength test can be performed to check the connection state of the twisted portion 4a before taking out the completed loop-shaped wire 4. It has become.

Next, the extraction means according to this actual example will be explained using FIGS. 6 to 10 (a) and (b).

Reference numeral 41 indicates a base that is driven in a horizontal plane by a first cylinder C1, and a substrate 43 that is movable in the vertical direction along a support 42 by a second cylinder C2 is supported on this base 41.

A main frame 44 is slidably supported on the base plate 43 on a sliding guide surface 45, and a guide shaft 45 provided in a part of the main frame 44 has a guide plate 46 extending in a direction perpendicular to the sliding direction of the main frame 44. Therefore, when the substrate 43 moves in the vertical direction, the main frame 44 moves while being constrained by the shape of the guide groove 47 .

The lower end of the guide groove 47 is a recess 48 that is slightly recessed toward the bottle 1j along the direction of the straight line connecting the pin axis 1j of the seventh arm 1' and the overlapping part of the loop-shaped wire 4 formed by the seventh arm 1f. Therefore, at the end of the downward movement of the base plate 43, the guide shaft 48 enters the recess 47a, and as a result, the main frame 44 is slightly shifted to the line 1j in FIG. 6.

When the main frame 44 is brought close to the index table 2 of the loop-shaped wire 4 manufacturing device, a rotating rod 49 is located at a position corresponding to the bin 1j by a rotating shaft 50. It is provided so as to be rotatable within a plane that includes.

What should be noted here is that the position of the rotation axis 50, which is the center of rotation, is located at a lower position near the bottle 1j, and as will be described later with reference to FIG. When the shaped wire rod 4 is hung on the rotating rod 49 and pulled, the center of rotation is placed on the line in the pulling direction so that the rotating rod 49 does not rotate unnecessarily.

The clamping position of the looped wire 4 is at which point A and v3! during the loop? These are the 8 points at both ends that have come off the chuck 11 of the I device.

What clamps the point A is a central clamping device, which consists of a central rod 51 and a pair of clamp plates 52 disposed on both sides of the central rod 51 and movable toward or away from the central rod 51.

The details of this central clamping device are as shown in the ninth factor, which is a view in the direction of the ■ arrow in FIG. 54 moves along the elongated hole 56 of the frame plate 55, and the other end of this link rod 53 is linked with the clamp plate 52 rotatably provided on the frame plate 55. , the clamp plate 52 has a central rod 51 fixed to a frame plate 55.
This is done by pressing down on it from both ends. The state in which the central clamp Rffff clamps the loop-shaped wire 4 is clearly shown in FIG. 10(a).

Further, the entire central clamping device is operated by a third cylinder C3 whose pressing force is controlled to be constant, in the movable direction of the raw frame 44, that is, as shown in FIG.
Handa fJkel! The strength of the soldering portion 4a is inspected by moving it in the direction toward +48 (twisted portion).

The device for clamping the eight ends of the loop-shaped wire 4 is a pair of end clamp plates 57, which may be, for example, a single clamping mechanism using a Tongel II mechanism that is substantially similar to the central clamp device. The cylinder that operates the end clamp plate 57 is the fifth cylinder C5.

Next, the operation of the extraction means according to this embodiment will be explained in the sixth section.
This will be explained using FIGS. 10A to 10A and 10B.

First, in the sixth cause, the second cylinder C2 is activated and the main frame 44 is lowered together with the board 43, resulting in the state shown in FIG. 7. Next, the fourth cylinder C4 and the fifth cylinder C5 operate to complete the central clamping system! ! 51, 52 and end clamp plates 57 clamp the center and end portions of the looped wire 4, respectively.

Next, the cylinder C2 is operated to raise the main frame 44 together with the substrate 43, and the clamped loop-shaped wire 4 is raised to the state shown in FIG.

Next, the process of testing the soldering strength of the loop-shaped wire 4 will be explained. In the eighth state, the fourth cylinder C4 operates to open the clamp plate 52, and the third cylinder C3 operates to move the center rod 51 to the left in FIG. This state is clearly shown in FIG. 10<b>. If the protrusion of the third cylinder C3 has a predetermined size, for example, several kilograms, this force will push the center rod 51 against the soldering f114a of the loop-shaped wire 4. If the loop-shaped wire 4 is soldered to a desired strength and is an acceptable product, the movement of the center rod 51 is stopped as the soldering is blocked by the portion 4a.

If the soldering is a passed product after the strength test is completed, the first cylinder C1 is activated and the main frame 44 is removed from and retreated from the table 2 together with the board 43, and the fifth cylinder C5 is activated and the end clamp plate 57 is activated. is opened, and the loop-shaped wire rod 4, which is a good product, is dropped into a predetermined position.

If this loop-shaped wA material 4 is a defective product, the soldering part 4a will open and the center rod 51 will not be able to be stopped.
-I will have to do a lot of work. This is therefore detected, for example, by a limit switch, in which case, for example, the first
It is sufficient to control the stroke amount of the cylinder C1 to drop the defective product at a position different from the position where the good product falls.

The brushing means 15 is the chuck 1 of the eighth arm 1h.
This is for mechanically removing flux, solder, iron powder, etc. attached to 1. The brushing means 15 of this embodiment is equipped with a brush rotated by a motor on the tip side, and as this brush is rotated, it rubs against the chuck 11 to remove solder etc. and clean iron powder etc. There is.

Therefore, according to the loop-shaped wire manufacturing apparatus according to this embodiment, since the preheating means 10 is provided, soldering can be performed more reliably.

Moreover, according to the loop-shaped wire manufacturing apparatus according to the embodiment,
Since the secondary cutting means 13 is provided, soldering can be completed by cutting the loop-shaped wire 4 at a certain position from the twisted portion 4a, and thereby the loop-shaped wire 4 can be finished. 4 will not be manufactured with both ends thereof unnecessarily elongated.

Further, according to the loop-shaped wire manufacturing apparatus according to this embodiment, at the position of the eighth arm 111, the 7-m1h
Flux, solder, iron powder, etc. adhering to the chuck 11 are cleaned and removed, and there is no risk of various troubles occurring during the next production of a new loop-shaped wire rod.
