Automatic edge finding method, system and equipment for laser cutting

Abstract

The invention discloses an automatic edge finding method, system and equipment for laser cutting. The automatic edge finding method, system and equipment for laser cutting have the functions of automatic positioning and edge finding, and before laser cutting is carried out, plates size, the edge reserving size, the edge finding speed and the following height are preset; the positioning points P1,P2 and P3 of the adjacent edges are selected on the plates to be processed. a cutting head starts to searches for the first point edge distance from the P1 point, the second point edge distance is searched from the P2 point, the third point edge distance is searched from the P3 point, and the cutting starting point O is calculated according to the three-point positioning after the edge finding isended; the positioning result is used for automatically calculating the deflection angle of the to-be-processed plates, so that the cutting pattern track is matched with the to-be-processed plates; aprocessing condition and the like are set, and then the plates can be cut. The automatic edge finding method, system and equipment for laser cutting can be used for can be used for rapidly, safely andefficiently improving the time of checking the plates, effectively preventing the plates from being scratched and causing harm to a human body.

Description

technical field [0001] The present invention relates to the technical field of laser cutting, and more specifically relates to a laser cutting automatic edge finding method, system and equipment. Background technique [0002] Laser cutting process replaces the traditional mechanical knife with a high power density laser beam. It has the characteristics of high precision, fast cutting, not limited to the limitation of cutting pattern, automatic typesetting, material saving, smooth incision, and low processing cost. It will be gradually improved or Replace the traditional metal cutting process equipment. When using a flat laser cutting machine to laser cut the plate, after the plate is placed in the processing range, there will be a slight deviation angle from the X-axis and Y-axis. It is necessary to manually adjust the cutting plate to make it horizontal and vertical to the X-axis and Y-axis before cutting. [0003] However, the manual operation to adjust the position of t...

Problems solved by technology

[0003] However, the manual operation to adjust the position of the board mainly has the following problems: first, manual operation to adjust the horizontal and vertical positions of the board is time-consuming and labor-intensive, and the labor cost is high; , the operation is inconvenient; third, the knife bar frame is generally conical, and the prying plate is easy to scratch the surface of the plate, and the workpiece with surface requirements will affect the product quality, or even cannot be used; fourth, when the cutting plate area is large, It is necessary to adjust the position of the plate repeatedly and back and forth many times, which is time-consuming and labor-intensive, and the processing efficiency is reduced; fifth, the processed plates are generally carbon steel plates, stainless steel plates, copper, aluminum and other metal materials, which are dense, heavy, and dangerous to move. prone to personal injury
