Description

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG.
Lead wire of electronic components such as g1 capacitor, L is the first
This invention relates to a lead wire bending device for electronic components that automatically bends the lead wires according to the distance W between the insertion holes H and H of the printed circuit board P, as shown in the middle of the figure.

Conventionally, the lead wire bending work for attaching various electronic components to the printed circuit board PK was done by manually bending the lead wires to match the 4W between the insertion holes H and H, or by using a mold. The lead wires were bent by pressing, but in the former case, there were problems in that it required a large number of hands when processing it into large wax, and the processing dimensions were poor. In the latter case, it is effective for processing electronic components of the same type with high precision and vagueness, but it takes time and effort to install the mold, and furthermore, it is necessary to manually place each processed component in a predetermined position. There were many problems, such as the need to supply a large amount of energy, which required a tedious amount of labor.

The object of the present invention is to provide a lead wire bending device that can perform bending/Ill processing in one continuous manner, facilitates large-scale processing, and has high processing dimensions. It is.

A spring '57 made of an integral wire is attached to the rear end of the spring '57. However, in this example, the lower front end of the spring 57 has its front end lower surface "l 7 A, 57 A facing both the left and right surfaces 111 [of the main holder portion 5a] and the lead wires, and presses the base of the L and bends the electronic component into the claw 41. 15. Reference numeral 58 denotes a detachable member attached to the inner surface of the left and right moving plates 18, and the detachable member 58 has an arc-shaped detachable member 59 facing the outside of the rear intermediate portion of the sub holder 5b. This is for removing electronic components with bent lead wires from the single-stream holder 5. Reference numeral 40 is a discharge chute for discharging electronic components with bent lead wires.

With this configuration, the rotary holder 5 rotates by driving and assisting the motor 11 to rotate the four rotating shafts 6. Therefore, when the electronic components supplied to the hopper 25 are sent out to the chute 27b over the first portion 27a, they are picked up one by one by the uil transmission holder 5 and sent toward the bending claw 15 by iΔ. In other words, ``The electronic component is 1 m long, and its main body B is the main holder part 5.''
It is fitted into the recess 7 of a, the lead wire is attached, and L is the sub holder part 5.
It is fitted into the notch 9 of b. As shown in FIG. 1(6), it is sent toward the bending claw 15 in the shape of the -118f line, as the rotary holder 5 rotates. However, the lead wire, L
When the guide surface 15A of the bending claw 15 is reached, as shown in FIGS.
It is sandwiched between A and the outer surface of the flange portion 8 of the sub-holder portion 5b, and is gradually bent toward the outer surface of the flange 8 as the I-shaped holder 5 rotates. When the electronic component with the lead wire bent in this manner reaches the rear intermediate portion of the rotary holder 5, it is removed from the rotary holder 5 by the detachable member 58 and discharged to the outside through the discharge chute 40.

Now, in the above-mentioned middle four example devices, 111
! When bending the lead wires of a type of electronic component with a predetermined left-right distance W, the screw of the distance A adjusting mechanism 29 should be bent through the field handle filter 5 so as to fit the entire length of the electronic component. By rotating the rod 54, the receiving part 27.2 of the hopper 25

and male screws 52, 5 of screw follower 4 screwed into '51.
As a result, the receiving portion 2 27 is opened and closed to adjust to a predetermined interval.

Next, when the screw rod 23 of the spacing adjustment mechanism 16 is rotated via the rotation handle 24 so as to match the required bending width of the lead wire, the left and right moving plates 18.1 are moved by the male screw portion 21.22.
8 performs an opening/closing motion to adjust the sub-holder portion 5b and the bending claws 15 to a predetermined interval. By doing so and driving the motor 11, the lead wires of the oil-type electronic components can be bent in a quadruple sequence with an accurate predetermined interval W in the same way as described above.

Note that a conveyor (not shown) may be provided to supply the electronic components to be bent to the hopper 25, and the hopper 2
Automatic feeding is possible by inserting a feed finger or the like (not shown) between the left and right receivers 27, 27 in order to feed the liquid from inside the base 27a to the chute 27b.

In addition, the discharge chute is attached to the operating plate 18.18 of the interval adjustment mechanism 16 as shown in 40A shown in FIGS. 8 and 9.
．． A pair of guide swash plates 42 are connected to each other via a guide plate 41 so as to be openable and closable from left to right. The printed circuit board P facing the rear end of 40A is intermittently transferred, and is automatically moved toward the insertion hole H of the printed circuit board P using a pusher Q that operates in synchronization with the transfer speed of the printed circuit board P. (It is also possible to lower the child parts and insert the lead wires.

As is clear from the above description, the present invention includes a main holder part that holds the main body of the electronic component supplied from the hopper in a recess formed on the outer peripheral surface, and a main holder part that holds the main body of the electronic component supplied from the hopper in a recess formed on the outer peripheral surface, and a lead wire at both left and right ends of the electronic component. A rotary holder is rotatably supported on the frame of the device, and consists of sub-holder parts on both the left and right sides which are in contact with each other and are recessed in the outer circumferential surface or held in the notch. The bending claw f for bending the lead wire faces through the gap m where the lead wire can be inserted on both the left and right outer sides, so it can be used to continuously bend the lead wire of electronic components with a high processing dimension of lψ. Since it can be bent, large-area processing can be performed in a short time, and furthermore, it is not necessary to manually feed electronic components one by one to a narrow predetermined position such as a mold, and the processing can be performed automatically.

Therefore, the present invention is extremely useful as a lead wire bending device for electronic components other than the conventional lead wire bending device.
