Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for conveying a continuous tape body to a perforation device used in particular for a perforation device for fine holes.

[Prior Art] Conventionally, in micro-hole drilling, in which fine holes are drilled into a thin sheet material, mechanical punching is particularly difficult when the diameter of the hole to be drilled approaches several tens of μM (microns). It is said that it is difficult to ensure accuracy when installing the punch to the device, so in a processing device for such drilling, the punch and die are supported by a hydrostatic bearing, so that the relative position of the punch and die is Proposals have been made for punching devices that guarantee the correct positional relationship.

On the other hand, in the above-mentioned micro-hole drilling equipment, in order to improve mass productivity and prevent variations in workpieces to improve yield, the drilling field, that is, the material to be drilled, is made into a continuous tape shape. A common configuration is that the material is transported to the perforated portion of the pipe.

Such continuous tape bodies generally use a contact-based friction drive method, but such continuous tape bodies are conveyed only in parts with relatively rough dimensional accuracy. There were no particular problems in that case.

[Problems to be Solved by the Invention] However, since the conventional conveying device is configured as described above, it is difficult to convey a continuous tape body in pitch units that guarantee accuracy in micron units. , as a result of the continuous tape body coming into contact with the perforating part of the perforating device,
There was a problem in that it caused damage to the fine holes that were machined.

Therefore, the method of conveying a continuous tape body to a punching device according to the present invention has been developed in view of the above-mentioned problems, and its purpose is to remove microscopic holes formed in a continuous tape body by a punching device. The objective is to prevent damage to the material and enable transportation.

In a conveying device and a perforation device configured to punch microholes in a continuous tape body being conveyed, the continuous tape body is conveyed in a non-contact state with respect to the conveying device.

Preferably, a porous body that discharges fluid is disposed on a conveyance path along which the continuous tape body is conveyed, and the fluid discharged from the porous body causes the continuous tape body to be brought into a non-contact state with respect to the conveyance device. I try to do that.

[Function] The continuous tape body is conveyed in a non-contact state with respect to the conveying device before and after the punching operation of the punching device on the continuous tape body.

Further, a porous body that discharges a fluid is disposed on a conveyance path through which the continuous tape body is conveyed, and the fluid discharged from the porous body brings the continuous tape body into a non-contact state with respect to the conveyance device. to work.
