Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for inserting an electronic component into a printed circuit board having a plurality of terminals arranged in a row.

Structure of the conventional example and its problems As shown in FIG. The held electronic component is lowered in the direction of the arrow with respect to the printed circuit board 2, and when the previously inserted electronic component 4 is inserted at an angle to the printed circuit board 3, the electronic component 4 is lowered in the direction of the arrow. If the child component 1 and chuck 3 are lowered in the insertion direction, there is a risk of interference with the electronic component 4. Therefore, when inserting the electronic component 1, make sure to leave a considerable distance between it and the previously inserted electronic component 4. There was a problem in that high-density insertion onto the printed circuit board could not be realized because it had to be opened and inserted.

OBJECTS OF THE INVENTION The present invention overcomes the above-mentioned conventional drawbacks and realizes high-density insertion of electronic components onto printed circuit boards.

Structure of the Invention The electronic component insertion device of the present invention includes: - a printer 1 for electronic components having a plurality of terminals lined up in a row; A machine that can move up and down in two steps in the direction (1'4 to 1)
the insertion head, and a drive unit having a mechanism for relatively moving the table and the insertion head in a plane,
By moving the table and the insertion head in two steps relative to each other in a plane before inserting the electronic components into the printer 1 and the board, high-density insertion of electronic components into the printer 1 and the board can be achieved. It is.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In the figure, 6 is an insertion head that holds the electronic component 1, 6 is a table that holds the printed circuit board 2, the tape /l/6 is fixed, and the insertion head 5 is a drive unit (with a built-in DC servo motor and a ball screw). (Figures omitted), the printed circuit board 2 is moved in a plane.

Next, the insertion head 5 will be explained in detail. The electronic component 1 is
It is held by guides 9 attached to the tips of the chucks 7 and 8. The 4-ick 7 and chuck 8 are fixed to the gliders 1Q and 11, and are opened and closed in the horizontal direction by the action of a piston 12, a spring 13, and an L/bar 14. 15 is a cylinder tube of the piston 12. The cylinder tube 15 is fixed to a piston 16, and the piston 16 slides up and down inside the cylinder tube 1. For Pino 1-inchup 1,
The piston 18 is spaced by an E-link 19 and slides up and down inside the piston tube 2Q.

Piston tube 20 is fixed to bracket 21. 22 and 23 are receivers for the vinyl 7, the tongue 16 and the piston tube 17, 24 is a stopper, and 25 and 26 are rotation Q catches. As described above, the insertion head 5 has a mechanism 116 that can move the piston 16 and the piston 18 up and down at two step intervals.

Next, the insertion operation will be explained. The insertion head 5 moves to a position point C1 slightly before the insertion position point B while chunking the electronic component 1 to be reversely inserted by the action of the DO servo motor of the drive unit.

Next, by supplying air from Aero D, the ship pin 18 is lowered. At this time, the entire insertion head 5 except the pig tube 1-tube 20, bracket 1-2j, and receiver 23 is lowered (indicated by an arrow). At the lower end of the insertion head 5,
The guide 9 also guides the upper end of the electronic component 4 that has already been inserted.
The position of the tip is at the bottom. Next, the entire insertion head 5 moves from the position point B to the reverse insertion position point A-i (arrow B) while maintaining the above state by the action of the driving section. At this time, the chuck guide 9 straightens the tilted electronic component that has already been inserted vertically.

In this state, air C1li is supplied to lower the piston 16, and the insertion of the electronic component 1 into the printed circuit board 2 is completed (arrow C).

As shown in Figure 2, two cylinders are provided inside the insertion head 6 to realize two-step vertical movement of the insertion head.
Furthermore, by dividing the planar movement of the insertion slot by the drive unit into two stages, high-density insertion of the electronic component 1 can be realized. Furthermore, by making the thickness of the guide 9 for picking up the electronic component extremely thin, it becomes possible to insert the electronic component in a pinch.

In the description of the embodiment, it is assumed that the table holding the printed circuit board 2 is fixed and the insertion head 5 moves in a plane, but it goes without saying that the reverse may be possible.

Effects of the Invention As described above, the present invention provides a mechanism that allows the insertion head that holds electronic components to move up and down in two stages, and also divides the insertion head and the table that holds the printed circuit board into two stages to achieve the 4th objective. By plane movement, it is possible to insert electronic components at a high density, which has great practical effects.
