Abstract

The invention relates to a laser marking control card for a laser marker. The laser marking control card comprises a digital signal processor, a field programmable gate array (FPGA) module, a memory extended module and a USB communication interface, wherein the digital signal processor performs real time treatment on marking data; the FPGA module is connected with the digital signal processor andis in charge of implementation of a logical circuit and controls a laser device of the laser marker; the memory extended module is connected with the digital signal processor and enlarges the memory space of the digital signal processor; and the USB communication interface is connected with the digital signal processor and transmits a digital signal processor program of an upper computer to the digital signal processor. In the invention, a special protective circuit is used, so electromagnetic interference is effectively filtered; and the digital signal processor (DSP) with low power consumption, stronger processing capability and customized high-performance is used as a processor, and a method for cladding copper at a large area is adopted to quicken emission of heat, thereby achieving continuous marking within 7*24h.

Description

【Technical field】 [0001] The invention belongs to the field of laser equipment, in particular to a laser marking control card and a laser marking machine. 【Background technique】 [0002] The electromagnetic environment of the working place where the laser marking machine is located is relatively complex. If the marking control card does not properly handle the electromagnetic interference, light leakage will be inevitable; the previous marking control card consumes a lot of power, so it is difficult to achieve 7*24 Hours of continuous marking; the general control card is not compatible with different brands of lasers, Q drives and galvanometers, which seriously affect the working efficiency of the marking machine. 【Content of invention】 [0003] The purpose of the embodiments of the present invention is to provide a laser marking control card, aiming to solve the problems of slow control speed, poor control stability and high power consumption in the existing laser marking...
