Embodiment 1

[0016] This embodiment is a more preferred solution, and its compliance device is as attached figure 1 As shown, it is mainly composed of a main support 20, a focusing mirror support 30, a beam expander 9, a solid mask 10, a turning mirror 11, a focusing mirror 12 and a laser generator. The laser generator is mainly composed of helium neon lamp 1, resonant cavity total mirror 2, Q switch 3, single lamp condenser 4, resonant cavity half mirror 5, and double lamp condenser 8. The red helium neon lamp is used as the color indicator light source. In order to reduce the length of the main support 20, the relevant components on the main support 20 are arranged in two rows: helium neon lamp 1, resonant cavity total mirror 2, Q switch 3, single lamp condenser 4 and resonant cavity half mirror 5 and the beam expander 9 and the dual-lamp condenser cavity 8 are respectively arranged in the main bracket 20 in two rows from left to right along the length of the main bracket. The correspond...

Embodiment 2

[0020] The marking device of this embodiment is attached figure 2 As shown, its components and figure 1 The marking device shown is the same, and the arrangement and connection of the components are basically the same. The difference is that the placement position of the solid mask 10 is different. In this embodiment, the solid mask 10 is placed at a position corresponding to the rear side of the beam expander 9 on the main support 20. Only the turning mirror 11 and the focusing mirror 12 are placed in the focusing lens holder 30. The focusing mirror 12 is placed on one side of the turning mirror 11, and the turning mirror 11 corresponds to the position of the solid mask 10, and its incident angle passes through the focusing lens holder. The light path provided between 30 and the main support 20 corresponds to the center position of the solid mask 10, and the reflection angle corresponds to the center position of the focusing lens 12.

Abstract

The present invention relates to a laser marking method for a reflective film and a marking apparatus therefor. The marking method comprises the steps as follows: a laser beam passes through a character die with a marking pattern after being expended, the laser beam is focused through a focusing mirror, the reflective film is disposed in front of or at the back of the focus, the laser beam including the marking pattern information is printed on the reflective film once and for all, and a mark same to the marking pattern is formed on the reflective film. The marking apparatus comprises a main stand one side of which is provided with a focusing mirror support, a color indicating light source arranged on the main stand, a resonant cavity total reflective mirror, a Q switch, a single lamp condensing cavity, a resonant cavity half reflective mirror, a double lamp condensing cavity, a beam expanding lens, a character die disposed on the main stand or the focusing mirror support, and a light transforming mirror and a focusing mirror disposed in the focusing mirror support. The advantages lie in that the marking speed for reflective material is greatly increased, and the structure of the marking apparatus is substantially simplified.

Description

Technical field [0001] The invention relates to a laser marking method and device, in particular to a reflective film laser marking method and a marking device. Background technique [0002] The reflective film with tiny glass beads as the substrate is a very widely used reflective material. In addition to a large number of such materials used in the traffic industry for road signs, roadside signs, and car license plates, they are also used as materials for making anti-counterfeiting marks. In order to prevent counterfeiting, the manufacturer puts a laser anti-counterfeiting mark on the reflective material and its products. [0003] The existing anti-counterfeiting mark is made by laser scanning method to make anti-counterfeiting mark on the reflective material. This method is to program the scanning program that forms the marking pattern into software and input it into the computer. The computer controls the laser head to scan the reflective material point by point. Formed on the...
