BRIEF DESCRIPTION OF THE DRAWINGS In the following, the device according to the invention will be described in more detail with reference to an exemplary embodiment shown in the drawings.

The apparatus according to the present invention shown in the accompanying drawings is a process for producing a laminated plate or a precision integrated circuit laminated plate by a plate press machine, particularly a multi-stage press machine, in each of which a lower portion to be processed on a press plate member 4 is required. This intermediate product on a press plate member 4 for producing an intermediate product consisting of a copper sheet 1, a prepreg sheet 2 mounted thereon and an upper copper sheet 3 further mounted thereon, This is for placing on the transport plate member 5 having the support pad 6. Before the intermediate product is fed to the plate press together with the conveying plate member 5, the cover pad 7 and the cover plate member 8 are stacked on the intermediate product. The plate press is not shown in FIG. 1, but is connected to the right of the figure. The illustrated transport path S communicates with the plate press. In the apparatus of the present invention, at least one set of intermediate products composed of the lower copper thin plate 1, the prepreg plate 2, and the upper copper thin plate 3 is placed on the transport plate member 5 as described above. However, as mentioned at the outset, it is also possible in principle to stack a plurality of sets of intermediate products, with the press plate member 4 interposed therebetween, to regularly stack and press together. The same applies to the case where the intermediate product is a laminate having one copper thin plate.

As is apparent from FIG. 1, the placement processing station 9 is linked to a pad placement processing station 10 for the support pad 6 at the transfer plate member reversing turning section. In addition, the press plate member transport line 11 is connected to the lower copper thin plate 1.
The prepreg plate transport line 13 is linked to a loading processing station 14 for the upper copper sheet 3. Place processing station 9
On one side edge, there is a press plate member transfer line 11 and a copper sheet mounting processing station 12 for the lower copper sheet, and on a diagonally opposite side edge, a prepreg plate transfer line 13 and an upper copper sheet mounting processing station 14. And a transfer path connecting the press plate member transfer line 11, the copper thin plate mounting processing station 12 and the mounting processing station 9, and the prepreg plate transfer line 13 and the upper copper thin plate mounting processing station 14. The transfer path connecting the transfer processing station 9 extends in parallel with the transfer running path S of the transfer plate member 5, and the transfer direction of the press plate member and the prepreg plate on which the copper thin plate is mounted in the transfer processing station 9. It extends in a direction perpendicular to 33.

[0013] It is connected to the above-mentioned plate press machine,
The transport plate member 5 having the support pad 6 and the transport running path S for the intermediate product placed on the transport plate member 5 are connected to the loading processing station 9. As is clear from the drawing, the cover pad 7 and the cover plate member 8 are placed on the intermediate product by the cover pad and cover plate member placement device 15 on the way to the plate press.

A copper thin plate mounting processing station 12 for mounting the lower copper thin plate 1 on the press plate member 4 and a copper thin plate mounting processing station 14 for mounting the upper copper thin plate 3 on the prepreg plate 2 are provided. As shown by the dashed lines in FIG.
7 and air suction device 1 attached to conveyor belt 16
8 Such a placing conveyor belt 16 itself is known, and it is also known to transport the copper thin plates 1 and 3 by the suction side edge frame 17 (for example, West German Patent 293).
No. 2845). The conveyor belt 16 is configured to be able to advance and retreat above the press plate member 4 and the prepreg plate 2 sent from the press plate member transfer line 11 and the prepreg plate transfer line 13 in the copper thin plate mounting processing stations 12 and 14. Therefore, for example, when placing the lower copper sheet 1 on the press plate member 4 at the copper sheet placing processing station 12, one lower copper sheet 1 is first picked up from the deposition location by the suction side edge frame 17, and this is removed. It is placed on the conveyor belt 16 in the retracted position, and then the conveyor belt 16 is moved forward as a whole and its front end is moved to a predetermined position on the press plate member 4. Next, the conveyor belt 16 is driven to rotate, and while the copper thin plate 1 riding thereon is moved forward, the entire conveyor belt 16 is retracted, and the copper thin plate 1 is gradually lowered onto the press plate member 4. . When the tip of the lower copper thin plate 1 is lowered onto the press plate member 4, the tip is pressed against the press plate member 4 by pressing means (not shown), and the lower copper thin plate is pressed against the press plate member 4. To keep it from moving. The above-mentioned air suction device 8 is interposed between the copper sheet 1 and the press plate member 4 that are gradually lowered, and the suction device moves back together with the conveyor belt and moves between the copper sheet 1 and the press plate member 4. Then, the lower copper thin plate 1 is brought into close contact with the press plate member 4. This mounting operation is similarly performed when the upper copper thin plate 3 is mounted on the prepreg plate 2 in the copper thin plate mounting processing station 14.

The upper copper sheet placing processing station 12, the lower copper sheet placing processing station 14, and the placing processing station 9 are installed in a dust-free clean zone 19. Inlet port 2 for prepreg plate conveyance path to this clean zone
At 0, an electrostatic dust suction device for cleaning the surface of the prepreg plate 2 is provided.

The operation of mounting the intermediate product on the transport plate member 5 in the mounting processing station 9 is performed as follows. That is, the press plate member 4 is transported in the press plate member transport line 11 by a belt conveyor device extending in a direction orthogonal to the transport running path S. The press plate member 4 is placed on a conveyor belt as a transfer path at the exit of the press plate member transfer line 11. This conveyor belt extends in the direction of arrow 30 and the press plate member 4
To the upper copper sheet processing station 12
Is introduced to Here, the press plate member 4 on which the lower copper thin plate 1 is placed as described above is brought to the placement processing station 9 by a conveyor belt as a transport path, where it is delivered to the clamp frame carriage 32.

On the other hand, similarly, the prepreg plate 2
Is transported in the prepreg plate transport line 13 by a belt conveyor device extending in a direction perpendicular to the prepreg plate. The prepreg plate 2 is placed on a conveyor belt as a transfer path at an exit of the prepreg plate transfer line 13. The conveyor belt extends in the direction of arrow 31, and the prepreg plate 2 is transported in the direction of arrow 30 and is introduced into the lower copper sheet placing and processing station 14. Here, the prepreg plate 2 on which the upper copper thin plate 3 is placed as described above is brought to the placement processing station 9 by a conveyor belt as a conveying path, and is transferred to the clamp frame carriage 32 there.

The press plate member 4 on which the lower copper thin plate 1 is brought to the mounting processing station 9 in this manner,
The opposite side edges are gripped by the clamp members of the clamp frame carriage 32. The clamp frame cart 32 travels in the mounting processing station 9 in a direction orthogonal to the transport path S, stops when it reaches the transport plate member 5 on the transport path S, and stops on both sides of the press plate member 4. The gripping action on the edge is released, and the stack of the lower copper thin plate 1 and the press plate member 4 is lowered onto the transport plate member 5 on which the support pads 6 are laid. Next, as described above, the placement processing station 9
Prepreg plate 2 on which upper copper thin plate 3 is brought
Are gripped by the clamp members of the clamp frame carriage 32 at opposite side edges thereof. Clamp frame cart 32
Travels in the mounting processing station 9 in a direction perpendicular to the transport path S, and stops when the stack of the lower copper thin plate 1 and the press plate member 4 reaches the transport plate member 5 on which the stacked body is placed. Then, the gripping action on both side edges of the prepreg plate 2 is released, and the stack of the upper copper thin plate 3 and the prepreg plate 2 is lowered onto the stack of the lower copper thin plate 1 and the press plate member 4. .
When a plurality of sets of intermediate products are formed on the transport plate member 5 in a stacked state, the above stacking operation is repeated.

The transport plate member 5 on which the intermediate product thus formed is placed is transported along the transport path S toward the plate press machine. The cover plate member 8 is placed.

After delivering the intermediate product to the plate press machine, the transport plate member 5 passes through a return path provided below the transport running path S, and reaches the lower conveyor belt of the placement processing station 9 shown in FIG. From there, the support pad 6 is placed on the conveyor belt lowered at the pad placement processing station 10, the support pad 6 is placed thereon, and the support pad 6 is raised to the same height as the upper conveyor belt at the placement processing station 9. It is transferred to a conveyor belt and waits for loading of intermediate products.
