Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a positioning device for a plurality of printed circuit boards when various electronic components are inserted or mounted on the printed circuit boards.

(b) Prior art In general, automatic mounting equipment for electronic components automatically traps and attaches electronic components such as chip-shaped resistors and capacitors, resistor capacitors with lead wires, and ICs to predetermined locations on a printed circuit board. A configuration is adopted in which the printed circuit board is transferred and placed on a so-called X-Y table that automatically moves in the KX direction and the Y direction.

Therefore, when placing one printed circuit board at a predetermined location, among the positioning bins inserted into the reference holes and individual holes provided on the single-trap printed circuit board, the positioning bins inserted into the reference holes are - The positioning bins fixed to the Y table and inserted into the other individual holes have different positions depending on the size of the printed circuit board or the various models, so the positioning bins for the individual general use are different from each other. This configuration allows the position to be adjusted each time.

As an example, as shown in Japanese Patent Publication No. 56-49474, a lever with a trap elongated hole is fixed to the fixed holder with a screw so that it can be slid according to the position of the positioning hole, and a positioning bottle is attached to the tip of the lever with a nut. A fixed embodiment is proposed.

However, if multiple printed circuit boards of the same type are mounted on a pair of guide rails? 1. Among the positioning pins inserted into the reference holes and individual holes of each printed circuit board, the positioning pin traps inserted into the individual holes may be adjusted in different directions depending on the size of the printed circuit board as described above. This had to be done for each bottle, which was extremely inconvenient.

(C) Brother] yJ's purpose This invention is 4xlj! When the same type of printed circuit board i is placed on a pair of rails, it is an object of the present invention to enable the position XX of a plurality of positioning bins inserted into individual hole traps to be adjusted by position adjusting means coupled to each other.

B) Structure of the Invention The present invention comprises a pair of parallel rails having grooves on which both ends of a plurality of printed circuit boards are slidably held, and a reference for the printed circuit boards arranged parallel to the rails. α several first positioning bins inserted into the holes, a plurality of second positioning bins inserted into the individual holes of the printed circuit board and provided on the moving plate, and the second position η′ Place combined into a bottle! ! y4 adjustment means, and the plurality of second positioning bins can be moved by the position fPc adjustment means.

(E) Embodiments The present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a mounting part of a printed circuit board positioning device of the present invention, and FIG. 2 shows a printed circuit board transfer device using the same positioning device.

In the drawing, (11 (11 (11 is a printed circuit board, (

A fixed plate, 0υ, is slidably attached to the fixed plate by a rack α and a binion 13, and a movable plate in which the second positioning bin is implanted, and (I4) is a position adjustment heir for rotating the binion. , α9 are vertical cylinders configured to move up and down like the guide rails described above.QeQη are support shafts that support the X table and Y table in the X and Y directions, respectively, and QFj is a base.

Next, to explain the operation of the device of the present invention, first, a printed circuit board (11 (Llfl)) is connected to a pair of rails (2) (J2).
is sequentially moved in the directions of the arrows (A) and K and is placed at a predetermined position through the valley grooves (3) + 3).
Push up the rails (2) (2) on the upper KX table (8) and Y table (9) with the SK, and insert the reference holes (41 (4) + 41
and individual holes (5) (5) (51 are each a first positioning bin 16) 16) 16) and a second positioning bin (7)
(The force is placed directly above the force if1.

In this state, when the rail +21 (21) on the X table (8) and Y table (9) is pushed down from the vertical cylinder QSK, the first positioning bin (6

At this time, the position of the second positioning bin +7)+7)+7) is determined in advance from each reference hole t, 1lt41(4) of the printed circuit board (il (L)(Ll) and the individual hole (51(5)(
It is set to a predetermined interval according to the 510 interval.

The first positioning bin +61+61+61 is fixed to the Y table via the fixed plate 01, and the second positioning bin (7 plate) is slidably provided on the fixed plate 01. , printed circuit board (9

In addition, in the above-mentioned example, the pinion (toward the right of 13 (arrow B)
), the moving plate 0υ moves in the direction of the arrow (CIK
When the pinion 03 rotates in the left direction (arrow D), the moving plate 0υ moves in the direction of the arrow (G) K.

(F) Effects of the Invention According to the printed circuit board positioning device of the present invention, after a plurality of printed circuit boards having the same positioning reference holes and individual holes are placed on a pair of guide rail traps, K. A first positioning pin and a second positioning pin are inserted into the reference hole for positioning and the individual hole.
The positioning pins of the plurality of second positioning pins are inserted and the positions of the plurality of second positioning pins are easily adjusted at the same time by moving the X table and the Y table to perform a predetermined work, for example, mounting an electronic component in a process. This eliminates the need to adjust the position of the second positioning bin every spring as in the past.
