A device for observing the state of flying ink droplets

Abstract

The invention belongs to the technical field related to inkjet printing and manufacturing, and discloses a device for observing the state of flying ink droplets, which includes a support base plate, a first monocular visual observation unit, a second monocular visual observation unit, and double mirrors Units, etc., where the support base is used to install other functional units, and determine the angle α of the binocular camera; the two monocular vision observation units are each composed of a CCD vision component and a matching LED light source, and they are jointly formed by the angle α. Execute the functional module that realizes the observation function of the binocular camera; the double mirror unit is located between the CCD vision component and the LED light source component, and is used to change the spatial state of the light path propagation. Through the present invention, parameters such as the volume and flight trajectory of ink droplets can be obtained more comprehensively and accurately, satisfying the comprehensive observation of ink droplets with various shapes; in addition, it is also convenient to change the spatial route of beam propagation, and solve the problem that the vertical flight distance of ink droplets is very small This leads to the problem of insufficient measurement space.

Description

technical field [0001] The invention belongs to the related technical field of inkjet printing manufacturing, and more specifically relates to a device for observing the state of flying ink droplets. Background technique [0002] Inkjet printing technology has broad application prospects in information, energy, medical, national defense and other manufacturing fields, and in recent years, it has been increasingly used in OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, smart Mongolia Flexible devices such as skins. Inkjet printing technology can print on demand, spray ink droplets to form patterned devices or uniform and dense packaging layers, and parameters such as the volume and speed of ink droplets have a great impact on the printing effect, and it is necessary to focus on detection and analysis. [0003] Specifically, in actual industrial-level production applications, flying ink droplet measurement technology is an important technical means to obser...

Problems solved by technology

For example, the method of weighing measurement can only obtain the average volume of a large number of ink droplets, and cannot detect a single ink droplet, nor can it detect the flying state of ink droplets; the method based on laser interference cannot detect the shape of ink droplets, and the cost is very high; while using The monocular vision method is used to observe flying ink droplets, which can usually only be observed in one direction, and the projected area, velocity and trajectory of ink droplets in a plane can be obtained
