High-speed industrial jet printing control system and method based on FPGA technology

Abstract

The invention provides a high-speed industrial jet printing control system and method based on the FPGA technology, and the system and method are applied to the industrial full-printing electronic field. The image processing, jet printing control and motion control functions are integrated to realize full-automatic printing, a traditional processing manner that a jet printer system processes images in a PC and then the images are transmitted to a jet printer control system to carry out jet printing at present is replaced, breakthrough is made in the bottleneck of the data processing speed in traditional jet printing, an array of a super large number of nozzles is supported, and the system and method are especially suitable for one-way jet printing of the industrial roll-to-roll jet printing technology. The jet printing control method can be used to coordinate and schedule functional sub modules to realize the jet printing function, the accumulated positioning error is overcome, and flexible acceleration and deceleration motion is carried out to control and ensure the ink jetting state; and the method is simple, and the jet printing precision is higher. Devices are controlled to carry out jet printing in the speed near the highest theoretical speed, and the production efficiency is greatly improved.

Description

technical field

[0001] The present invention relates to a control system and method of jet printing equipment, in particular to a high-speed jet printing control system and method implemented by FPGA technology and applied to the field of all-printed electronics. Background technique

[0002] Fully printed electronics refers to a technology that uses printing methods to form electronic components and circuits in the electronics manufacturing industry. The fastest growing technology is the use of inkjet printing technology to print conductive lines on printed circuit boards (PCBs). Anti-etching layer, solder resist layer or character graphics, instead of traditional screen printing and chemical etching methods, reduce production processes, materials and environmental pollution. One of the main problems in the current printing technology of fully printed electronics is to develop the control system of advanced inkjet printers for large-scale production, especially in the roll-...
