Embodiment Construction

[0056] Describe the present invention below in conjunction with specific embodiment:

[0057] A control method of an electronic pattern machine for realizing uniform discretization of patterns in this embodiment includes the following steps:

[0058] Step 1: Create a pattern data file: the pattern data file includes a header file, key point data and pattern data;

[0059]The pattern data is generated through the following steps:

[0060] Step 1.1: According to the sewing process, the pattern is divided into several segments of basic geometric figures that are connected in sequence. The basic geometric figures include straight line segments, circular arcs, circles and free curves. The data of points are key point data;

[0061] Step 1.2: Uniformly discretize each segment of the basic geometry according to the following method:

[0062] A: Uniform discretization of straight line segments:

[0063] Step A.1: Set the two points of the given line segment as O(0,0) and P(x,y), a...

Abstract

The invention provides a method for controlling an electronic pattern making machine for realizing uniform discretization of patterns, aiming to solve the problems of running instability and pattern distortion caused by nonuniform discretization of patterns of the electronic pattern making machine in the prior art. According to the method, a plurality of straight line segments, circular arcs, circles and free curves for forming the patterns are discretized uniformly, the obtained relative coordinates of the pattern points indicate the relative running vector of a needle of a sewing machine on the frame of the sewing machine, the integrated pattern data files are stored in the electric control system of the electronic pattern making machine, the pattern data files selected by the user are read by the electric control system, and the pattern data are analyzed reversely to control an X-axis stepping motor and a Y-axis stepping motor to operate together with a servo motor.

Description

technical field [0001] The invention relates to a control method of an electronic pattern machine for realizing uniform discretization of patterns. Background technique [0002] The electronic pattern machine is an industrial sewing machine with three axes working together. The three axes are the main axis Z that controls the up and down reciprocating movement of the needle and the XY axis that controls the front, back, left, and right movements of the cloth frame in the horizontal plane. During the sewing process, the main shaft reciprocates in the vertical direction at a constant speed according to the set speed: the needle moves from the highest point to the entry point where the needle is about to penetrate the fabric, to the lowest point of the needle, and then to the exit point where the needle just leaves the fabric , and finally reach the highest point. The process of the needle from the cloth exit point to the highest point and then to the cloth entry point is the ...
