BRIEF SUMMARY
FIELD OF TECHNOLOGY
The present invention relates to an automatic inserting apparatus for electronic parts for automatically inserting lead wires of the electronic parts, successively supplied, into inserting holes in a printed circuit board.
BACKGROUND TECHNOLOGY
Hitherto, in an automatic inserting apparatus of this type, in order to improve the production of printed circuit boards with electronic parts actually mounted thereon, it is necessary to quickly insert lead wires of the electronic parts into inserting holes in the printed circuit board without error.
In the conventional apparatus, a guide mechanism for guiding the lead wires of the electronic parts towards the inserting holes in the printed circuit board is so arranged as to contact the printed circuit board directly to enable the insertion of the electronic parts retained by a retaining mechanism. While the lead wires of the electronic parts can be assuredly inserted into the inserting holes in the printed circuit board by the above described guide mechanism, the guide mechanism has to contact the printed circuit board directly, and there is a problem in that the interval between the electronic parts to be inserted must be rendered great, making it difficult to achieve a high density actual mounting of the electronic parts on the printed circuit board.
In view of the above, in order to improve the actual mounting density of the electronic parts on the printed circuit board, there has been proposed an apparatus wherein guide pins are provided so as to extend through the inserting holes in the printed circuit board in a direction counter to the direction of insertion of the electronic parts whereby the lead wires of the electronic parts can be guided by the guide pins so as to be introduced into the inserting holes in the printed circuit board. In the apparatus of the above described construction, since a mechanism for introducing the lead wires of the electronic parts into the inserting holes in the printed circuit board does not directly contact the surface of the printed circuit board, the actual mounting density of the electronic parts on the printed circuit board can be improved. Hereinafter, the conventional automatic mounting apparatus for the electronic parts utilizing this mechanism will be described.
As shown in FIG. 1, a taping component 1 of radial type is such that two lead wires 5 of electronic parts 4 which extend in the same direction are retained in equally spaced relationship by a cardboard tape 2 and an adhesive tape 3. It is to be noted that, in the drawings, 6 represents feed holes formed by punching the cardboard tape 2 and the adhesive tape 3, and the taping component 1 can be transported at any time by driving a feed mechanism while projecting parts (not shown) of the feed mechanism of the inserting apparatus are engaged in the feed holes 6. The taping component 1 so fed is such that, as shown in FIG. 2, the lead wires 5 can be cut by a plain cutter 8 adapted to be slid in a direction shown by the arrow A by an external drive such as an air cylinder and having an L-shaped projection 7 at the free end thereof, and a lead cutter 9 arranged so as to extend in a horizontal direction and slidable in a direction shown by B. In addition, by the plain cutter 8 and a tape cutter 10 arranged so as to extend vertically and slidable in a direction shown by C, the cardboard tape 2 and the adhesive tape (not shown) of the taping electronic component 1 is cut. Within the above described plain cutter 8, a cylinder 11, a piston 12, and a spring 13 are incorporated, and when air is supplied from an air inlet 14 in the plain cutter 8, the piston 12 is slid so as to compress the spring 13 and to permit a rod 15, provided integrally with the piston 12, to project outwards from a cutting plane of the plain cutter 8 thereby to retain the cardboard tape 2, but when the air supply is interrupted, the piston 12 is slid in the reverse direction by a compressive force of the spring 13 to retract the rod 15 inwards from the cutting plane of the pl
