specific Embodiment approach

[0038] In order to better understand the present invention, a specific embodiment is used to describe it. It is worth emphasizing that the effect of this embodiment is not substantially different from the various embodiments within the protection scope of the present invention, and the effects described in the present invention can be achieved. and solve the above problems;

[0039] like image 3 As shown, a 1:1 image is generated in the computer according to the engraving platform. The laser ranging sensor 4 is combined with the laser ranging sensor column 7. Each detection column uses itself as the origin to generate x and y coordinates, and according to the generated point The coordinates calculate the distance from the point to the detection column.

[0040] The number of the entire ant colony is m, the number of points formed by the engraved pattern is n, and the distance between point i and point j is d ij (i, j=1, 2, 3, 4, ..., n), the pheromone concentration on the p...

Abstract

The invention discloses a plane laser engraving machine positioning method, which belongs to the technical field of plane laser engraving, and is characterized by comprising the following steps: acquiring an optimal engraving route, correcting and positioning a plane laser engraving machine in real time based on the optimal engraving route, and combining a preset number of laser distance measuring sensors and laser distance measuring sensor columns, and the distance of the laser engraving heads at different height positions at the same horizontal position can be measured. The method has the beneficial effects that the pattern is pre-engraved, the pattern is analyzed by the system, the pre-engraved pattern is dispersed into a plurality of points, the ant colony priority algorithm is creatively introduced into positioning of the plane laser engraving machine, the optimal engraving route is planned by using the ant colony priority algorithm, and the positioning precision of the plane laser engraving machine is improved. The position of the laser engraving head is adjusted in time according to feedback data obtained by comparing with optimal engraving route point position data calculated by the system, and the problem that the position of the engraving head is determined by recording the number of turns of motion of a motor in a traditional laser engraving machine, and accuracy is low is solved.

Description

Technical field: [0001] The invention belongs to the technical field of plane laser engraving, and more particularly relates to a positioning method of a plane laser engraving machine. Background technique: [0002] The plane laser engraving machine is mainly used to add marks to the product. The traditional laser engraving machine determines the position of the engraving head by recording the number of revolutions of the motor. When the engraving head is slightly inclined, the engraving position will be shifted, or the motor If the position is lost, the product marking position is unqualified, and the product to be marked will be scrapped or reworked. Invention content: [0003] In order to solve the above problems and overcome the deficiencies of the prior art, the present invention provides a positioning method for a plane laser engraving machine, which can effectively solve the problem that when the engraving head is slightly inclined, the engraving position will be of...
