Efficient laser marking method and device for multi-style small-batch articles

Abstract

The invention discloses an efficient laser marking method and device for multi-style small-batch articles. The laser marking method comprises the steps that a drawing is prepared and typeset on a computer, the thickness of marks in the drawing is set, a contour is marked on a working platform according to the drawing, the marked articles are placed on the contour, the focusing height is set according to the thickness, and then laser marking is carried out. The laser marking device comprises a rack, and the working platform and a three-axis linkage mechanism which are distributed front and back are connected to the rack. The three-axis linkage mechanism is connected with a laser marking head located above the working platform, the three-axis linkage mechanism is electrically connected with a control box, and the laser marking head is also electrically connected with the control box. The efficient laser marking method and device for the multi-style small-batch articles can be suitable for laser marking operation of multiple types of small-batch articles, and further has the advantages of being high in machining efficiency, convenient to operate, high in safety, capable of conveniently removing pollutants, high in machining precision, stable in control and good in dust removal and environmental protection performance.

Description

technical field [0001] The invention relates to the field of laser marking, in particular to a high-efficiency laser marking method and a laser marking device for multi-style and small-batch articles. Background technique [0002] Laser marking machine is a device that uses laser beams to mark exquisite patterns, trademarks and text on various material surfaces. Existing laser marking machines need to perform positioning and focusing operations during actual use. The common positioning operations are positioning edge (point) positioning and visual recognition positioning, and the common focusing operation is cross laser crosshair focusing. [0003] Positioning edge (point) positioning means that the staff first sets a marking position on the working platform, and then looks for a positioning edge (point) on the working platform according to the marking position and the shape of the marked object. During the marking process, the positioning operation can be completed by plac...

[0003] Positioning edge (point) positioning means that the staff first sets a marking position on the working platform, and then looks for a positioning edge (point) on the working platform according to the marking position and the shape of the marked object. During the marking process, the positioning operation can be completed by placing the marked item close to the edge (point) position; however, in this type of operation, the marked item corresponding to each style needs to re-select the position Edge (point), the operation is cumbersome and the efficiency is low, and it cannot be applied to the marking operation of multi-style and small-batch items

[0004] Visual recognition and positioning, generally by taking pictures of the marked items on the working platform, identifying the outline of the marked items and calculating the placement position and direction of the marked items through program calculations, so as to be able to identify the mar...
