Automatic cutting machine and scribing method thereof

Abstract

The invention relates to the technical field of automatic cutting, and discloses an automatic cutting machine and a scribing method thereof. The automatic cutting machine acquires the distance between the pen point of a scribing pen and the surface of a to-be-scribed material; if the distance between the pen point of the scribing pen and the surface of the to-be-scribed material is not in a preset range, up and down position of the scribing pen is adjusted until the distance between the pen point of the scribing pen and the surface of the to-be-scribed material is in the preset range. By controlling the distance between the pen point of the scribing pen and the surface of the to-be-scribed material, excessive contact or separation between the pen point and the to-be-scribed material can be avoided, so that scribing is enabled to be accurate and quick.

Description

technical field [0001] The invention relates to the technical field of automatic cutting, in particular to an automatic cutting machine and a marking method thereof. Background technique [0002] An automatic cutting machine is a device that automatically cuts fabrics, the most common fabrics being cloth or leather. At present, the head of the automatic cutting machine cuts the fabric laid on the cutting table according to the pre-made cutting data. In addition, there is also an automatic cutting machine with integrated multi-process at present. In addition to the cutting knife, the machine head is also equipped with a punching, scribing or creasing device to process the fabric in an integrated manner. These treatments require the fabric to be laid on a flat cutting table. However, due to the process or other reasons, the table top of the cutting table is often not flat enough, which affects the effect of subsequent cutting, punching, scribing or creasing. [0003] For ex...

AI Technical Summary

Problems solved by technology

[0003] For example, if there are protrusions or depressions on the cutting table, during the marking process, the line can be smoothly marked at the protrusion position, then the fabric may not be scratched at the depression position (using a chalk-like marking pen), or Because it is too far away from the fabric, the scribing is inaccurate (use inkjet to scribble); if the line can be drawn smoothly at the concave position, it is likely to damage the nib at the protruding position

In actual production, inaccurate scribing requires erasing and redrawing, and the scribing pen needs to be replaced when the pen tip is damaged, which reduces production efficiency and increases costs
