Laser printing path planning method and laser device

Abstract

The embodiment of the invention provides a laser lettering path planning method and a laser device, and relates to the technical field of laser imprinting. The laser printing path planning method comprises the following steps: determining a laser starting position of a target pattern; according to the initial position, path lines are formed in the target pattern in a winding type filling mode; adjusting the distance between the path lines; and laser imprinting is carried out along the path lines after the distance is adjusted. Target patterns can be filled more fully in a winding type filling mode, and the laser effect is better; moreover, by adopting a winding type filling path, the idle stroke of machine operation can be greatly reduced, the laser efficiency is higher, and a large amount of time is saved.

Description

technical field [0001] The invention relates to the technical field of laser marking, in particular to a laser printing path planning method and a laser device. Background technique [0002] With the rapid development of the semiconductor industry, there is an increasing demand for laser printing in the packaging process, and customers require more and more types and styles of logos to be printed. At this stage, the logo printing method is machine filling. The method of multiple oblique line segments is filled sequentially. This method fills too many lines and too many breakpoints, which leads to a long time and low efficiency for logo printing. In addition, for a logo with a slightly more complicated shape, the filling degree of multiple oblique lines is not high, which will affect the laser printing effect and reduce the product yield. Contents of the invention [0003] The purpose of the present invention includes, for example, to provide a laser printing path planning...

[0002] With the rapid development of the semiconductor industry, there is an increasing demand for laser printing in the packaging process, and customers require more and more types and styles of logos to be printed. At this stage, the logo printing method is machine filling. The way of multiple oblique line segments is filled sequentially. This way fills too many lines and too many breakpoints, which leads to a long time and low efficiency of logo printing.

And fill with multiple oblique lines. For logos with a slightly more complex shape, the filling degree is not high, which will affect the laser printing effect and reduce the product yield.
