Problems solved by technology

[0003] However, since the driving waveform of the nozzle contains many adjustable parameters, the adjustment method based on manual experience or grid is not only time-consuming and laborious, but also with the drift of the nozzle state (mainly piezoelectric ceramic fatigue phenomenon ), the state of the nozzle is difficult to keep consistent for a long time, which greatly limits the application of inkjet printing technology

Embodiment Construction

[0062] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0063] See figure 1 , the ink drop ejection state adjustment system for the piezoelectric printing nozzle of the present invention includes a CCD camera 4 , a computer computing platform 1 , a nozzle driving controller 2 , and a piezoelectric printing nozzle 3 .

[0064] The computer computing platform 1 uses a CCD camera to capture the state of the ink drop ejected by the piezoelectric printing nozzle, obtains the state parameters of the ink drop through image processing, and extracts the corresponding characterization parameters of the ink drop according to the working principle of the piezoelectric printing nozzle. According to the gap between the current ink drop characterization parameters and the expected ink drop characterization parameters, the artificial bee colony algorithm is used to optimize, and an expected driving waveform driving parameter is obtained, ...

Abstract

The invention, which belongs to the technical field of ink-jet printing, provides an ink droplet ejection state adjusting system and method for a piezoelectric printing nozzle. The system is composed of a computer computing platform, a nozzle drive controller, a piezoelectric printing nozzle and a CCD camera. One end of the nozzle drive controller is connected with the computer computing platform and the other end is connected with the piezoelectric printing nozzle; and the CCD camera is connected with the computer computing platform. The nozzle drive controller generates a drive signal for the piezoelectric printing nozzle and simultaneously carries out time sequence controlling on the drive signal; the piezoelectric printing nozzle fluctuates in an ink cavity under the drive signal provided by the nozzle drive controller and the fluctuation is spread to spraying holes to form ink droplets; and the CCD camera captures states of ink droplets ejected by the piezoelectric printing nozzle.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a system and method for adjusting an ink drop ejection state of a piezoelectric printing nozzle. Background technique [0002] Inkjet printing technology is a computer-controlled, high-speed, high-quality dot-matrix, graphic non-plate printing process by spraying picoliter-level droplets on a variety of printing substrates. This technology has processing advantages such as low pollution, low energy consumption, simple processing technology, no need to contact with the substrate, and suitable for processing products with three-dimensional structures. At present, the ink available for printing can also have certain physical and chemical properties. Different from traditional document printing, inkjet printing technology has now become a low-cost and high-precision technical means in the fine processing of small-scale circuits, and is considered to be an importa...
