3D scanning modeling method and system of laser marking machine and marking machine thereof

Abstract

The invention provides a 3D scanning modeling method of a laser marking machine. The method comprises the steps of: (S1) intercepting and capturing focusing signal sending instructions; (S2) intercepting and capturing mobile signal generation instructions; (S3) intercepting and capturing feedback signal receiving instructions; (S4) intercepting and capturing coordinate information set sending instructions; (S5) intercepting and capturing adjusting signal sending instructions; (S6) intercepting and capturing feedback signal adjustment sending instructions; and (S7) intercepting and capturing scanning and modeling instructions. The invention further provides a 3D scanning modeling system; the system comprises a marking platform, a marking module, an automatic focusing unit, a 3D scanning unit, an adjusting unit and a control terminal; and the marking module is controlled by the control terminal to move in the vertical direction or the horizontal direction. Each physical unit is controlled through the control terminal; and during marking, the 3D scanning of patterns can be directly performed to generate actual 3D patterns, so that the direct pattern marking is realized in an originalposition, the optimal marking effect is maintained, and the technical effect of full-automatic modeling is achieved.

Description

technical field [0001] The invention relates to the technical field of laser marking and cutting equipment, in particular to a 3D scanning modeling method and system for a laser marking machine and a marking machine thereof. Background technique [0002] With the development of laser marking technology, marking on three-dimensional materials has become a gradually mature technology. Through the improvement of the structure of the equipment, the 3D marking technology is more convenient and efficient, but because the physical marking surface may not be on the same surface On a level plane, there are still many defects in the prior art for 3D curved surface physical marking, such as Chinese patent CN 207464464U, which discloses a large-format 3D ultraviolet laser marking machine, including a lower cabinet, which is located on the upper surface of the lower cabinet. The worktable, the lifting mechanism arranged at one end of the worktable, and the laser marking mechanism arrange...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned technology has the following problems: First, the laser cannot accurately mark the height of the actual object during marking (that is, the object is not on the focal length), which will cause different depths during marking and fail to achieve the desired effect; Second, ordinary users generally do not have the ability to model 3D graphics. There are great difficulties in the use of importing and modifying 3D graphics. Users often need to hand over to professionals for 3D modeling before importing software. It will increase the user's use cost and time cost; third, if you use the ordinary simple texture operation method, you need to choose various surface types, and you need to set various parameters such as diameter, which cannot fully match the actual object.

If the parameters of various diameters or surfaces are incorrectly filled in with the real object, the focal length will be inaccurate and the marking effect will be unsatisfactory; fourth, the imported 3D graphics are not in the same batch as the real object, and there are sizes such as height, curved surface, and width difference

The position of the marking will also be different from the position of the imported graphics when modeling, resulting in distortion of the surface data and unpreparedness, resulting in inaccurate focal length and unsatisfactory marking effect
