Multi-jet synchronous printing system based on a distributed architecture

Abstract

This invention relates to the field of high-precision industrial printing technology and discloses a multi-printerhead synchronous printing system based on a distributed architecture, including a workstation, an FPGA processing board, and print head modules. This system separates non-real-time large-scale computing from real-time high-precision control through a distributed architecture. When increasing the number of print heads, only additional computing tasks need to be added to the workstation, and logic units and I / O interfaces are expanded on the FPGA. The workstation parses the image data of each print job, completes dynamic load segmentation, establishes a segmentation index table, and then packages the data and embeds timestamps, ensuring that the FPGA processing board has sufficient time to complete decompression and caching, and also ensuring precise start of the printing operation at the specified time point. The distributed parsing has strong scalability, and the FPGA processing board constructs a global synchronization mechanism to ensure precise alignment of data from different channels in the time dimension. Waveform queries are performed on data packets to generate personalized drive waveforms adapted to each piezoelectric print head, resulting in excellent multi-printer collaboration.
