BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction conveyance device.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional suction / conveyance apparatus, which is generally designated by 10 and has suction cups 15a and 15b attached to both ends of a main body 11. Although it is formed in a funnel shape as clearly shown in FIG. 4, it is composed of a conical hollow portion d and a cylindrical suction cylindrical portion f connected from the top of the conical hollow portion d. An annular pad plate p made of felt is attached to the peripheral edge of the bottom portion of d, and the main body 11 is hollow, but the drive rod 12 and the drive portion 13 are connected to communicate with this, Can be moved left and right along the guide rail 14 in the direction indicated by the arrow a. Body 1
A blower 16 is connected to 1 via a pipe 17. The drive unit 13 can drive the main body 11 freely along the guide rails 14, but further has a mechanism for moving the drive rod 12 up and down in the direction of arrow b.

When the flat plate having a relatively large thickness is transported by the suction transport device 10 as described above, it can be transported in the a and b directions without any problem.
For example, assuming that the copper foil material 19 having an area of 1 m ² and a thickness of about 50 μm is laminated in multiple layers on the mounting table 18, only one uppermost copper foil material 19 will be suckers 15a and 15b.
In the case of adsorbing and transporting by suction, the inside of the main body 11 is sucked through the pipe 17 by the drive of the blower 16, but this is also communicated with the conical hollow portions d of the suction cups 15a, 15b. The copper foil material 1 which is inhaled by the above, and therefore the pad plate p is laminated on the mounting table 18.
When applied to the uppermost copper foil material 19 of 9 and raised in the direction of b by the drive unit 13, if it is a conventional flat plate having a sufficient thickness, it is adsorbed by these suction cups 15a and 15b without any problem, The copper foil 19 is conveyed upward while maintaining its shape. In the case of the copper foil material 19, the suction cups 15a and 15b are used.
The copper foil material 1 is absorbed inside the pad plate p of
Since 9 is thin, it has shapes 19a and 19b that are picked up toward the center of the pad plate p, and wrinkles occur. If this copper foil material 19 is used for wiring a printed board, for example, it will be a defective product and the desired printed board cannot be obtained.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above problems, and as described above, even a thin plate material such as a copper foil material having an area of 1 m ² and a thickness of 50 μm is not damaged. An object of the present invention is to provide an adsorption / conveyance device which can retain its shape without any wrinkles and can convey it to a desired position without wrinkling.

[0005]

[Means for Solving the Problems] The above object is to provide at least two rows of pipes each having a flat bottom wall side by side in a frame, and to form a large number of small holes in the bottom wall so that a blower is formed in the pipe. It is achieved by a suction and conveyance device characterized in that the frame body is movable by being connected to the air suction port.

[0006]

A large number of small holes are formed on the bottom wall surfaces of at least two rows of pipes, and these small holes are communicated with the blower to suck air. When they come into contact with the foil material, they are efficiently sucked at the contact surface, and when strongly attracted to move the frame along a predetermined trajectory, the shape of the copper foil is changed without damaging the copper foil. It can be safely transported without.

Here, the copper foil material 60 to be adsorbed is shown by a one-dot chain line. (The copper foil material 60 is slightly different in size from the copper foil material 19 shown in the conventional example, but similarly has a thickness of 50 μm.)

A cylinder 20 is attached to the center of both side edges of the hollow frame 31, and the drive rod 21 is attached to the suction tubes 22a and 22b.
Furthermore, on both sides of this, guide bushes 37a, 37a, 3
7b and 37b are attached, guide rods 38a, 38a, 38b and 38b are slidably guided through the center holes, and the lower ends thereof are attached to the suction tubes 22a and 22b. In FIG. 1, G is a seal ring.

The inner space 32 of the hollow frame 31 is provided with a pipe 33.

As shown in FIG. 2, a large number of small holes h are formed in the bottom wall surface of the suction tubes 22a and 22b, which communicate with the inner space 40 .

The embodiment of the present invention is constructed as described above. Next, this operation will be described.

Now, as shown in FIG. 1, a case where the copper foil material 60 laminated on the mounting table H is sucked and conveyed will be described. As described above, this copper foil has an area of 1 m ² and a thickness of about 50 μm.

When the blower 34 is driven, the inner space 32 in the hollow frame 31 is sucked, and the bellows 39a, 39a,
The inner space 40 of the suction pipe bodies 22a and 22b is sucked through the suction pipes 39b and 39b. The entire suction transfer device 30 is brought to the position shown by a drive unit (not shown). When the cylinder 20 is driven, the drive rod 21 extends downward. This allows the bellows 39a, 39a, 39b, 39b
Also, the downward movement of the guide bushes 37a, 3
7a, 37b, and 37b, 37b, the guide rods 38a, 38a, 38b, 38b are accurately moved downward, and the copper foil material 60 immediately below is directly attached to the suction pipes 22a, 2b.
