DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

This invention relates to an automatic insertion machine for electronic components, in which many types of taped electronic components, that is, taped axial lead components and taped radial lead components, and stick-packed ICs are held respectively and fed selectively to a carried-in printed-circuit board in a predetermined sequence, and the leads of the electronic components are inserted in the appropriate holes in the printed-circuit board.


BACKGROUND TECHNOLOGIES

In the conventional automatic insertion machine for electronic components of this type, a plurality of insertion spindles, which correspond to the shapes and sizes of electronic componenents supplied selectively in a predetermined sequence, insert the leads of electronic components in their lead inserting holes in the respective different inserting positions. It is, therefore, necessary that the carried-in printed-circuit board should be moved so that each predetermined lead inserting hole in the printed-circuit board may align to one of the aforementioned respective different insertion spindle positions. As a result, the range of movement of a printed-circuit board traverse device becomes too wide to make it for practical use. Thus the conventional machine has a defeat that the traverse device is large-sized.
This invention is intended to reduce the size of a printed-circuit board traverse device and improve the efficiency of an inserting operation for inserting the leads of many types of electronic components by selectively indexing the insertion spindle suitable for each electronic component supplied selectively and by inserting the leads of the electronic component into the inserting-holes in the printed-circuit board at a single fixed position.


DISCLOSURE OF THE INVENTION

The subject matter of the present invention lies in the construction of an automatic insertion machine for electronic components comprising:
a printed-circuit board traverse device for supporting a printed-circuit board and traversing it so that an inserting hole in the printed-circuit board for inserting a lead of an electronic component is placed in a single fixed position;
an insertion spindle column which is located above the traverse device, comprising a plurality of insertion spindles each having a different insertion chuck, and indexes one of the plurality of insertion spindles which is corresponding to a selected electronic component to the single fixed position;
a taped component holding and feeding device having a plurality of taped electronic component feeders arranged for holding many taped electronic components and feeding them sequentially to the insertion spindles, one of the taped component feeders being optionally selected and indexed to the vicinity of the single fixed position, the taped component holding and feeding device feeding the optionally selected electronic component to the insertion spindle indexed to the single fixed position; and
a stick-packed component holding and feeding device for taking out an electronic component in a stick selected optionally, from a stick holding rack in which many electronic components in the sticks are held, and carrying out and supplying the electronic component to the insertion spindle indexed to the single fixed position.
The printed-circuit board traverse device moves the printed-circuit board for inserting the leads of electronic components into the holes in the printed-circuit board at the single fixed position and stops them sequentially. The insertion spindle column supports a plurality of insertion spindles and indexes the insertion spindle which is suitable for the taped electronic component being inserted or for the electronic component selectively supplied from the stick. If the electronic component being inserted is a taped component, it is fed to the insertion spindle when the appropriate taped electronic component feeder is indexed to the predetermined position near the single fixed position. The appropriate taped electronic component feeder has been selected from many taped e
