Correcting system and correcting method of leather cutter

Abstract

The invention relates to the technical field of automatic leather cutting and particularly relates to a correcting system and a correcting method of a leather cutter. The correcting system comprises a correcting plate, a correcting module, a projector and a computer. The correcting method comprises the following steps: putting the correcting plate and the correcting module on a workbench at a time to correct to obtain coordinates, corrected at different positions, of two groups of projective points; and then, establishing a mathematical formula for the projective point at each position to obtain a mathematical formula of the coordinate of each projective point and the leather thickness. According to the system and the method disclosed by the invention, by virtue of correcting under two conditions, the originally complex correcting process is changed into the mathematical formula and then combined with the computer to realize automatic correcting, so that the correcting process is relatively quick, and the leather obtained by cutting is relatively accurate in dimension, and thus, the waste is avoided and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of automatic leather cutting, in particular to a correction system and a correction method for a leather cutting machine. Background technique [0002] In the process of leather cutting, the projector is used to mark the cutting pattern on the leather first, and then the knife is cut along the projection pattern, but not all the light projected by the projector is perpendicular to the workbench of the leather cutting machine, most of the light They are all emitted from the projector as the starting point, so when the leather with a certain thickness is placed on the workbench for pattern cutting, if the cut pattern is not corrected, it will deviate from the theoretical pattern, so in the leather Different thickness leather needs to be corrected before cutting. [0003] The correction of leather cutting in the prior art adopts an equivalent replacement method. First draw a grid or correction points on the wo...

AI Technical Summary

Problems solved by technology

[0003] The correction of leather cutting in the prior art adopts an equivalent replacement method. First draw a grid or correction points on the workbench, then let the projector correct the grid or correction points, and then prepare according to different thicknesses of leather. Calibration boards of different thicknesses simulate leather of equal thickness for calibration. This method requires the preparation of multiple sets of calibration boards. Calibration boards are required for each cut, and the error is relatively large.
