As described above, there are various sizes of the wiring board 4, for example, the length W X and the width w Y.
Has a large size of 500 mm × 400 mm. Such a large wiring board 4 is easily bent when pressed by the clamp mechanism 15. FIG. 4 exemplifies a state in which the large-sized wiring board 4 is pressed by the clamp mechanism 15 and bent, and the lower surface of the wiring board 4 is pressed by the plurality of protrusions 14 of the movable plate 13 and bent downward. do not do. However, since there is nothing to press on the upper side, it is curved upward as shown. Due to this bending, the mounting position is displaced, the positioning becomes inaccurate, and the electronic component 3 cannot be mounted at the correct position. In order to prevent the above curve, it is effective to securely clamp the central portion of the wiring board 4 and the intermediate portion between the front and rear edges. However, the air suction method is suitable for the clamp of the central portion, and the wiring board 4 has various sizes. If this is changed, the intermediate portion between the central portion and the edge also changes, so it is necessary to consider this point.
The present invention has been made in view of the above, and an object of the present invention is to provide a mechanism that prevents the large-sized wiring boards 4 of various sizes from curving and securely clamps them.

In the above-described curving prevention clamp mechanism, the suction mechanism and the two sets of pressing mechanisms are arranged so as to be movable in the X and Y directions with respect to the bottom surface of the housing of the automatic component mounting machine. The suction mechanism is set at a position corresponding to the center portion of the wiring board, and the bottom surface of the center portion is sucked by the air by the suction disk raised by the air cylinder. The two sets of pressing mechanisms are respectively set at positions corresponding to respective intermediate portions of the front and rear edges of the wiring board, and each flat pressing plate is lifted by the air cylinder to press the bottom surface of each intermediate portion upward. Further, each pressing plate with claws is rotated by an air cylinder to press the upper surface and the end surface of each intermediate portion. From the above, the wiring board is the bottom surface of each middle part of the front and rear edges,
The top surface and the end surface are pressed to be well-balanced and securely clamped. Further, air suction on the bottom surface of the central portion prevents the occurrence of bending, and the electronic component can be accurately mounted at a predetermined position. it can. In the guide mechanism arranged on the bottom surface of the housing, the three intermediate and front and rear movers fitted to the guide rod are each movable in the X direction, and the middle mover has a shaft. The supported support member is rotatable about the eccentric shaft. Therefore, the suction disk supported by the support member can be arbitrarily set in the XY directions, whereby the suction mechanism is set at a position corresponding to the central portion of each wiring board having a different width. . Next, each Y-direction position setting section of the two sets of pressing mechanisms is rotatable by 180 ° within a range in which the supporting blocks axially supported by the front and rear moving elements support each other. For the two common support blocks for the pressing plate with the claw, one of the set positions in the Y direction is selected and the support member is fixed. Therefore, the flat pressing plate and the pressing plate with the claws arranged on the supporting member can move continuously in the X direction and stepwise (described later) in the Y direction. As a result, the two sets of pressing mechanisms are set at the positions corresponding to the respective intermediate portions of the front and rear edges of the wiring boards having different lengths. With the above settings, the wiring boards of various sizes are securely clamped without being curved as described above.
