针对粗糙表面喷印装置的研究与开发

Study and development of a printing device on rough surfaces

针对新建楼房所测层高数据在粗糙地面打印困难的问题,开发了一种用于类似楼房中粗糙地面进行自动印刷的喷印装置.设计一种利用步进电机驱动丝杠带动打印喷头运动,由STM32F103微处理器对需打印数据进行分析计算,控制打印喷头中的七段码结合海绵油印层,完成对该数据的自动印刷装置,并且对系统的机械结构进行了优化设计,从而有效地提高了打印速率.实验测试结果表明,该装置可打印3位数字,每个数字间距0.5cm,数据清晰且保存时间久.

To solve the problem of printing the height data of newly-built buildings on rough surfaces, we developed an automatic printing apparatus for similar rough surfaces in buildings. The print head of the device was driven by a stepper motor. The data to be printed was analyzed and calculated by a STM32F103 microprocessor which controlled the printing head in the seven-segment code and sponge layer mimeograph. The mechanical structure of the system was optimized to improve the print speed. Experimental results show that the device can print 3-digital numbers in 0.5 cm of digital spacing clearly and preserve for a long time.
