Abstract

The laser marking machine comprises a control system, an adjusting mechanism, a transmission positioning mechanism, a support and a detection camera, the control system is arranged on one side of the support, a partition plate is arranged in the support and divides the space in the support into an upper cavity and a lower cavity, and the adjusting mechanism, the transmission positioning mechanism and the detection camera are all arranged in the lower cavity. And one end of the control system extends into the upper chamber. A positioning mark is arranged on a product needing to be marked, a detection camera is used for transmitting a picture of the product to a display screen in real time, and after the coincidence degree of the positioning mark on the product and a reference mark in a control system is adjusted, a laser is started to mark the product. Accurate marking is set by arranging the transverse adjusting mechanism, the transmission positioning mechanism and the vertical adjusting mechanism, the position error of batch repeated marking is smaller than or equal to 1 mm, laser marking is rapid, and marking of all positions of a large-breadth flat plate can be completed in a short time through high-power output.

Description

Technical field [0001] The present invention relates to laser marking, specifically to the laser marking machine and marking method of the large-format radiator character used in rail transit. Background [0002] Radiator element surface needs to be equipped with IGBT module, the radiator surface of the module side needs to be marked with characters, before the use of screen ink printing photosetting method, there are processes such as blending ink, printing, light solidification, etc., but also need to buy a large number of silk screen printing templates, there is a lot of time waste, economic waste, low efficiency and other defects. [0003] At present, the character mark printing of the large-format radiator of the rail transit in China is commonly used in the silk screen printing method, positioning through the silk screen printing template, manual brush ink penetration screen to form characters on the surface of the radiator, and then ultraviolet curing or baking curing. Thi...
