A plurality of lead guides 9 are arranged on a circle while being coupled with the base 4 of the hand 3 such that the hand 3 is located on the outside of the plurality of leads upon gripping the CPT socket and operated centrifugally or centripetally by means of a cylinder 10. Furthermore, a plurality of lead bending pawls 13 are arranged on a circle on the inside of insertion holes at the under side of a printed board and operated centrifugally or centripetally by means of a cylinder 14 through a link mechanism 15. With such structure, an electronic device having leads arranged nonlinearly can be inserted automatically.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic component inserting machine for inserting an electronic component with leads into a predetermined hole of a printed circuit board.

[0002]

2. Description of the Related Art The conventional automatic parts insertion mechanism is "Introduction to automatic assembly of electronic parts" (issued on July 30, 1981) P124
As described in Nos. To 126, the electronic components such as the radial lead component, the axial lead component, and the DIP type component in which the leads are arranged in a straight line are targeted.

[0003]

The above-mentioned prior art does not consider insertion of an electronic component such as a CPT socket for a television having leads arranged non-linearly, and such an electronic component is automatically operated. There was a problem that it could not be inserted.

It is an object of the present invention to enable automatic insertion of electronic components having leads arranged in a non-linear manner.

[0005]

In order to achieve the above object, the present invention provides a plurality of lead outside bending claws, a plurality of lead guides, and a plurality of lead bending claws which are arranged in accordance with the lead positions of electronic components.

[0006]

The plurality of lead external bending claws arranged in accordance with the lead position of the electronic component deforms each of the plurality of leads of the electronic component held by the hand to the outside of the hole position of the printed circuit board into which the lead is to be inserted. Multiple lead guides
Since each lead deformed to the outside can be bent back so as to match the position of the hole in the printed circuit board into which the lead is to be inserted, the lead is surely guided by the inner surface of the lead guide and inserted into the predetermined printed circuit board hole. Is inserted.

The plurality of lead bending claws aligned with the lead positions of the electronic component can bend each of the plurality of leads of the electronic component inserted in the hole of the printed circuit board toward the back surface of the printed circuit board. It can be securely fixed to the printed circuit board.

[0008]

Embodiments of the present invention will be described below with reference to FIGS.

As shown in FIG. 2, a television CPT socket 1 to be inserted has a plurality of leads 2 arranged on the circumference thereof.

As shown in FIG. 1, a hand 3 is attached to a base 4 and is vertically moved by a cylinder 5. For the plurality of lead external bending claws 6, the hand 3 has a CPT socket 1
It is provided on the circumference so as to be inside the plurality of leads 2 arranged circumferentially when gripped by, and is operated by the cylinder 7 via the link mechanism 8 in the centrifugal and centripetal directions.

The plurality of lead guides 9 are provided so as to be connected to the base 4 of the hand 3, and are arranged on the circumference so as to be outside the plurality of leads 2 when the hand 3 holds the CPT socket 1. The cylinder 10 operates in the centrifugal and centripetal directions. The position of the inner surface 9'is aligned with the edge position 12 'of the insertion hole 12 of the printed circuit board 11 when operated in the centripetal direction.

A plurality of lead bending claws 13 are circumferentially provided on the lower side of the printed circuit board 11 so as to be inside the insertion hole 12, and are centrifugally and centripetally directed by a cylinder 14 via a link mechanism 15. To work.

Next, the operation will be described.

As shown in FIG. 3, the CPT socket 1 is
The hole at the center is grasped by the hand 3, and is carried to the upper side of the lead outside bending claw 6 by an insertion operation mechanism (not shown) such as a robot. Here, the cylinder 7 operates and the lead outside bending claw 6 moves in the centrifugal direction via the link mechanism 8 to deform the lead 2 to the outside. The amount of deformation of the lead 2 at this time is set so that even if the lead external bending claw 6 returns to the inner side, it does not spring back and return to the original position.

Next, the cylinder 7 operates and the lead external bending claw 6 returns to the centripetal direction via the link mechanism 8, and the cylinder 1
0 operates to move the lead guide 9 in the centripetal direction, and presses the lead 2 against its inner surface 9'and bends it back to the edge position 12 'of the insertion hole 12 of the printed circuit board 11.

In this state, the hand 3 is moved to the insertion hole 12 of the printed circuit board 11 as shown in FIG.
The leading end of is inserted into the insertion hole 12 of the printed circuit board 11. Here, the cylinder 10 operates, the lead guide 9 returns to the centrifugal direction, the lead guide 9 is separated from the lead 2, and only the hand 3 is moved to the cylinder 5.
Is lowered and the insertion is completed.

Subsequently, the cylinder 14 operates and the lead bending claw 13 moves in the centripetal direction via the link mechanism 15 to bend the lead 2 to the back surface side of the printed circuit board 11,
The CPT socket 1 is fixed to the printed board 11, and all the component inserting operations are completed.

[0018]

According to the present invention, it is possible to automatically insert an electronic component, such as a CPT socket for a television, in which leads are arranged in a non-linear manner, so that the number of steps for assembling a printed circuit board can be reduced.
