Embodiment Construction

[0036] The invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Disclosed in the present invention is a double sheath aerosol spray printing method and the device used in the method. The method and the device involved will be described below. Such as Figure 1-10 As shown, the method involves a jet printing device including an aerosol generating component and an aerosol jet printing head, and integrating the two into one device can make the overall structure of the jet printing device more compact. Such as figure 1 As shown, the aerosol generating component includes an interconnected atomizing component 2 and a droplet sorting component 1, and the droplets 90 form droplets 91 with different particle sizes through the atomizing component 2, which can pass through the droplet sorting component 1 The aerosol 95 with relatively uniform particle size and stable density was obtained. Such as Figure ...

Abstract

The invention discloses a double sheath aerosol jet printing method and related jet printing head. The method comprises the following steps: Step 1, atomizing the liquid droplets to form mist droplets; Step 2, sorting the mist droplets to obtain consistent sizes The small particle size droplet; Step 3, use the Venturi tube to inhale the small particle droplet and mix it with the carrier gas to form an aerosol; Step 4, pass the focused sheath gas around the aerosol to shrink the aerosol to form a dense aerosol Beam; step 5, pass protective sheath gas around the nozzle to the dense aerosol beam, suppress the divergence of the dense aerosol beam after leaving the nozzle, in order to adapt to the above method, a plurality of sheath gas channels are provided around the jet printing head aerosol supply channel , the present invention sorts and focuses on the aerosol jet printing and protects the aerosol when it is jetted out, which improves the density stability of the aerosol, and at the same time effectively prevents the diffusion of the aerosol after jetting out, improving the The fineness of aerosol jet printing can avoid the occurrence of overspray.

Description

technical field [0001] The invention relates to the field of electronic printing, in particular to a double-sheath aerosol jet printing method and a jet printing head for realizing jet printing of high-precision micropatterns or microstructures. Background technique [0002] Traditional printed electronics technologies include gravure printing, screen printing, inkjet printing, photolithography and laser etching, etc. However, some disadvantages of traditional printed electronics technologies greatly limit the further development of printed electronics technologies. For example, the graphic positioning accuracy is low and the resolution is low (>20μm), the production process is complicated and toxic, the manufacturing cost is high, and the utilization rate of materials is low. In order to overcome the above problems, aerosol jet printing technology emerged as the times require. Aerosol jet printing technology is a non-contact, direct-writing digital additive manufacturing...
