摘要
为了提高激光打标卡标刻精度和标刻速度的要求,提出一种基于USB接口激光打标控制卡的设计:控制卡首先通过PFGA主控模块控制USB传输模块,进行接收上位机传送的图像标刻数据,接着将标刻数据传输至SDRAM存储模块,在数据完成接收后,最终将激光打标卡的数据分别传输至X-Y振镜和激光器内,从而实现预设图像的标刻;激光振镜打标卡通过USB通信模块所传输的标刻数据,应按照XY2-100协议进行,FPGA控制模块选用了Cyclone III芯片,USB传输模块选用FT2232H芯片。打标卡能够快速、完整的获取PC上位机在进行图像分解后的标刻数据,并能稳定的将数据传输至激光器和X-Y振镜实现图形标刻。实验表明:该激光振镜打标卡稳定性较强、处理速度较快、标刻精度较高。
In order to improve the marking accuracy and marking speed of laser marking card,a design of laser marking control card based on USB interface is proposed.The control card first control the USB transfer module through the PFGA master control module,to receive the image marking data sent by the host computer,and then mark data transmitted to the SDRAM memory module,when receiving data completed, and finally the laser marking card data were transferred to the X-Y galvanometer and laser, so as to achieve the default image of the mark.The laser galvanometer marking card transmit the marking data through the USB communication module, should be in accordance with the XY2-100 protocol,FPGA control module selected Cyclone III chip,USB transmission module selected FT2232H chip.The marking card can obtain the marking data quickly and completely after PC analysis image,and transfer the data to the laser and the X-Y galvanometer and implement the graphic marking stably.Experiments show that：this laser galvanometer marking card stability is strong,faster processing,marking a higher precision.
