Embodiment Construction

[0056]The invention will be described in detail below with reference to the accompanying drawings.

[0057]ReferFigure 1 ~ 6A method of cutting a PVC board based on a MARK point positioning function, including the following steps:

[0058]1) First, iffigure 1 The industrial camera is displayed to the position near the spindle of the engraving and milling machine, such asfigure 2 The function of the camera and the spindle is shown by the camera bias to the camera and the main shaft relative offset XsSums. Proportion of coordinates and actual working coordinate systems in known cutting files1: 1. Calculate the transition ratio in the camera coordinate system and the cutting file program by the current height camera MARK point imaging.2: 1, such asimage 3 The maximum range of the camera coordinate system is (xcYc).

[0059]2) Second, the engraving and milling machine is based on the cutting program file to find the strategy of Mark points, such asFigure 4 Indicated.

[0060]3) According to step 2)...

Abstract

A method for cutting PVC boards based on the Mark point positioning function. The industrial camera is installed near the main shaft of the engraving and milling machine, and the relative offset between the camera and the main shaft is calculated through the function of camera offset tool setting; the engraving and milling machine according to the cutting program The document formulates a strategy for finding Mark points; through the strategy of finding Mark points, the center coordinates of 4 pairs of Mark points and the current axis coordinates fed back by the control panel when the Mark point is found are respectively obtained through the industrial camera, and the coordinates of the current camera coordinate system are converted according to the Buddha Rolling Stone to In the coordinate system of the cutting program file; compare the converted 4 Mark point coordinates with the center coordinates of the Mark point in the cutting program file coordinate system. If there is no offset, the position of the PVC material is normal. If there is an offset, then Correct the position of the PVC material. The method of the invention can improve the operation efficiency of the machine.

Description

Technical field[0001]The present invention belongs to the technical field of high-precision CNC equipment, and is related to a method of binding to machine vision and Mark point assist in the engraving and milling machine such that the cutting accuracy can be effectively improved when the PVC board is performed.Background technique[0002]The engraving and milling machine is a kind of CNC machine tool in the major domestic factory enterprises. It has the advantages of small tools, high-power, spindle high speeds, and processing larger hardness materials, which make up for the deficiencies of the cutting bed and engraving machines. Place. Its emergence makes the production cost of the machining high hardness material, improved the level of automation of the engraving and milling industry, reduces the process of manual work. Users can also adjust the quality of different production requirements by parameter adjustment, and improve the quality of finished products.[0003]The engraving and...
