As shown in FIG. 2, the reference surfaces 11a and 12a are formed in a bent shape. On the other hand, a suppression board 20 and a fixed reference bin 21 are provided between the rails 11 and 12, and the bins 21a of the suppression plate 20 and the fixed reference bin 21 are arranged in a direction perpendicular to the plane of FIG. 1, that is, arrow C in FIG. , and are provided so as to be freely protrusive and movable in the D direction. Similarly, between the rails 11 and 12, a movable reference bin 22 having a bin 22ai provided so as to freely protrude in the C1D direction is fitted onto the screw shaft 23, and its lower surface in the figure is still in contact with the guide plate 25. The screw 1iqjl 23 is connected to the shaft 27 connected to the motor 9E via the umbrella @26A126B. I'm doing this.

Note that the printed circuit board 29 is spaced at intervals of 1.5 mm as shown in Figure '5443. It has two reference holes 29a and 29b labeled B.

The 7th installation position of the printed circuit board is ``white'', and the determination number 1 is 4?4 JN, as shown above. , 51, input the board number KN'0, which displays the type of the board 29 to be determined, from the keyboard 3 into the main fii control unit 2 ().
The board number KNO is set for each board (1 layer) i1. ). Then, the main flilJ controller 2 searches the memory 5 4rp and reads out the board size data KDT corresponding to the board design number 1<NO. Board dimension data 1g1.

3B') 19B also rotates (!: starts) in the E direction between the Boo IJ 17B. In this state, when the flint substrate 29 is placed on the belts 19A and 19B from the right end in Fig. 1, the substrate 29 is conveyed in the E direction by bells 19A and 19B 3. At this time, since the interval WA is set to a length e corresponding to +1iLA of the substrate 29, the substrate 29 is conveyed in the E direction without causing skew. transported to.

The tip 29c of the substrate 29 being transported in the E direction reaches the line sensor T, and the distance WD between the position of the tip 29C read by the sensor 7 and the fixed reference bin 21 is the substrate dimension take K D
When the distance L of T becomes equal to D, the main control unit 2
stops the drive of the motor 9A and transfers the conveyor bell) 19A, 19.
The conveyance of the substrate 2'9 in the E direction by B is stopped. next,
゛The main control unit 2 drives the bins 21a, 22a and the press plate 20 of the reference bins 21 and 22, which are set in advance to the interval W B = LB, and the bins 21a, 22a and the press plate 20.
as shown in FIG.
9A and 19B to protrude in the TFC direction, and the bin 21
a, 22a are fitted into the reference holes 29a, 29bK of the substrate 29. Therefore, the bottles 21a and 22ak are further raised in the direction of the substrate surface 29, and the substrate @29 is moved along with the pressing plate 20 to the substrate surface 29.
Standard of rail 11.12 through e [11] 11a, 1
2a to position the substrate surface 29e at a predetermined height. As a result, the board 29 is positioned at a predetermined position on the device 1, and in this state, parts and the like are manually mounted on the board 29 by a robot or the like.

Note that, as in this embodiment, the reference surfaces 11a and 111) are formed in the rules 11 and 12 as vertical positioning means, and the substrate surface 29e is pressed against the reference surfaces 11a and 12a for positioning. For example, the substrate surface mJ29e can be set to a predetermined height level regardless of the thickness of the substrate 29.

When the mounting of components etc. on the board 29 is completed, the bin 21
a, 22a and the pressing plate 20 descend in the D direction, and the bottle 21
&, 22a and the pressing plate 20 are separated from the substrate 29, so that the surface 29e of the substrate 29 is also within 1 from the reference planes 11a and 12a.
and falls onto the conveyor belts 19A, 19B. Therefore, the motor 98 is driven again and the conveyor belts 19A, 19
The board 29 is transported and discharged in the E direction by B, and the transport positioning operation for the next new board 29 begins.

(6) As described in detail of the invention, it has vertical positioning means;
A book rail 11.12 is provided movably so that the interval WA thereof can be varied, and at least two reference bins 21.22i are movably provided so that the interval WC between the reference pins is variable, and The bottles 21a and 22a,
Conveyance surface T I of conveyance means such as conveyor belts 19A and 19B
Since it is provided so as to be able to protrude freely from i''C, it is possible to freely carry and position printed circuit boards 29 having various dimensions, and this can contribute to the realization of robotization in component mounting work, etc. for circuit boards 29.
