| The aim of this study was to achieve the high-density, high-precision, and three-dimensional objectives of the jet printing device, we studied and designed the digital control system for the jet printing platform. Using the general methods of the vector control, automatic control and numerical control system, implementing the master circuit module with FPGA, and matching the image acquisition positioning and parameter extraction with DSP, using the technology of CNC and CCD to conduct real-time position, the nozzle compositing the staggered array and angle mount mode could be controlled. The nozzle was subjected to control of the translation, rotation motion and image recognition, and the temperature and flow process control of the ink jet head. Numerical control of the array dual-mode jet printing platform was realized, which could print with paralleling paste and high speed above the substrate. Through data processing and distribution of the multiple-row nozzles, real-time injection control, device logic control and state management could be realized. By one data sending and receiving of the multiple-row nozzles, a complete row of pixel matrix could be printed. And the arrangement could be changed by accurately adjusting the printing lines according to the offset of platform and resetting of the control program. The platform designed could simplify the traditional technological process, solve the bottleneck of internal transmission speed, and there was no need to change the printing plate for every change of the new products. |
