Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic component insertion machine for inserting electronic components into a printed circuit board, and in particular to an electronic component insertion machine for inserting electronic components into a printed circuit board.
The present invention relates to an electronic component insertion device having a push rod that presses the top of the electronic component downward when inserting the electronic component, such as a transistor, into a printed circuit board with IJ-wires led out in the same direction.

Conventional technology In recent years, female component mounting technology has become more compact and denser as products become lighter, thinner, and smaller.
The insertion pitch of lead wires is also becoming more diverse.

Hereinafter, a conventional method of holding down the electronic part 8 will be explained with reference to FIGS. 2 and 3 a%q. The electronic component 1 separated from the electronic component series 5 supplied by a component supply unit (not shown) is
After the lead wire 2 is clamped and transferred to the transfer chuck 6, the receiver is passed to the clamping claw 15, and the lead wire 2 or the electronic component 1 is
The main body is positioned below the push rod 12 while being held between the legs. Thereafter, the guide pin 8 rises from the lead wire fixing device 9 located below the printed circuit board 3, passes through the insertion hole 4 formed in the printed circuit board 3, and connects the taper provided in the clamping claw 14. The lead wire 2 is guided through the shaped hole 7.
is located below. Next, from above the electronic component 1, the solenoid valve 10. The push rod 12 is lowered by air pressure from the action of the pressure reducing valve 11, and the gripping claws 16 are opened, whereby the electronic component 1 is held between the push rod 12 and the guide bin 8. Thereafter, the insertion shaft 13 which holds the push rod 12. Due to the simultaneous lowering of the guide bin 8, the electronic component 1 is inserted into the insertion hole 4 of the printed circuit board 3.
The fixed blade 17. is inserted into the lead wire fixing device 9 and is provided on the lead wire fixing device 9. The lead wire 2 is cut to a predetermined length by the action of the movable blade 16 and bent to fix the electronic component 1 to the printed circuit board 3, completing the insertion.

Problems to be Solved by the Invention However, with the push rod fixed at an absolute position as described above, for example, when guiding a two-lead component and a three-lead component with a lead pitch of 6 elbows using the same clamping claw. As shown in Figure 4, electronic components with an insertion pitch of 2 or 5 mm may have bends in the component body or lead wires due to misalignment with the center of the push rod, making it difficult to accommodate the diversification of insertion pitches. This leads to a decline in the quality of electronic components, a deterioration in the independence of electronic components to printed circuit boards, and high-density insertion becomes impossible.

In view of the above-mentioned problems, the present invention provides an electronic component insertion device that can set the position of the push rod to an optimal position matching the central axis position of the electronic component body.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention makes it possible to move the axis of the push rod that presses the component in the direction of the arrangement of the guide holes or guide grooves that guide the lead wires of the component. It was established.

Function: With the above-described configuration, the present invention makes it possible to set the position of the push rod according to the IJ lead wire pitch of the electronic component, and also enables the position setting of the electronic component according to the type and shape of the electronic component with the same lead wire pitch. Become.

Example An embodiment of the present invention will be described below with reference to FIG.

The electronic component 1 separated from the electronic component series 5 supplied from a component supply section (not shown) is held by the clamping claws 15 after the IJ-wire 2 is clamped and transferred to the transfer chuck 6. It is positioned below the push rod 12 while holding the lead wire 2 or the main body of the electronic component 1 between them. Thereafter, the guide pin 8 rises from the lead wire fixing device 9 located below the printed circuit board 3, passes through the insertion hole 4 formed in the printed circuit board 3, and passes through the taper provided in the clamping claw 15. It is guided through a shaped hole 7 and positioned below the lead wire 2.

Next, from above the electronic component 1, the solenoid valve 10. The push rod 12 is lowered by pneumatic pressure from the action of the pressure reducing valve 11, and by opening the clamping claw 15, the electronic component 1 is moved between the guide pin 8 and the guide pin 8.
It becomes a state where it is caught between the two. At this time, the position of the push rod slides the insertion shaft 13 by a predetermined distance depending on the lead wire pitch of the electronic component to be inserted. In this method, the slider 20, which is integrated with a pair of holding blocks 19 that hold the insertion shaft 13, is slid by the operation of the drive cylinder 18.

Thereafter, the electronic component 1 is inserted into the insertion hole 4 of the printed circuit board 3 by simultaneous lowering of the insertion shaft 12° guide pin 8 holding the push rod 12, and the fixed blade provided in the lead wire fixing device 9 is inserted into the insertion hole 4 of the printed circuit board 3. 17. Lead wire 2 due to the action of movable blade 16
is cut to a predetermined length [7] The electronic component 1 is fixed to the printed circuit board 3 by bending, and the insertion is completed.

Effects of the Invention As described above, according to the present invention, since the push rod is provided so that its axial center position can be moved in the arrangement direction of the guide hole or guide groove that guides the lead wire of the component, bending of the lead wire, Since there is no change in the shape of the electronic component such as bending of the component body, the quality of the electronic component after insertion is stable. Furthermore, the independence of electronic components from the printed circuit board is improved, and the number of insertions is increased, allowing for high-density insertion. Furthermore, it is possible to expand the number of insertable parts and improve the insertion rate.
