Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] A method of regulating and controlling electrofluidic printing by capacitive feedback, comprising the steps of:
[0027] (1) Detect the capacitance between the nozzle of the ink-filled inkjet needle and the printing substrate through the capacitance detection module, and send the capacitance data to the data processing module;
[0028] (2) The data processing module processes the capacitance data sent by the capacitance detection module after receiving it, and sends the feedback data to the needle voltage output control module after processing;
[0029] (3) After receiving the feedback data sent by the data processing module, the needle voltage output control module adjusts the input voltage applied to the ink-filled inkjet needle.
[0030] In this embodiment, the capacitance detected by the capacitance detection module is the microcosmic ups and down...
