Spray nozzle cleaning device and manner

Abstract

The invention discloses a spray nozzle cleaning device and manner. According to the spray nozzle cleaning device, the cleaning device is horizontally moved to the position below a micro drop spray nozzle through a mechanical conveying device, ultrasonic cleaning is performed on the micro drop spray nozzle, and the micro drop spray nozzle is fast dried by adopting a convection drying row grate. Bymeans of the spray nozzle cleaning device and manner, the cleaning efficiency of the micro drop spray nozzle can be improved, the immersion depth of the micro drop spray nozzle is accurately controlled, and it is effectively prevented that damage is caused to the micro drop spray nozzle in the cleaning process.

Description

technical field [0001] The invention relates to the field of droplet ejection supporting devices, in particular to a nozzle cleaning device and a nozzle cleaning method. Background technique [0002] In the droplet ejection experiment, the quality of the nozzle determines the size of the ejected droplets, and the diameter of the droplet nozzle is generally at the mm level or even at the um level. After each experiment, it needs to be cleaned in time, otherwise it is easy to cause the spray liquid to remain in the nozzle and block the nozzle, so that it will not be able to spray normally the next time it is sprayed. The cost of the micro-droplet nozzle is very high, generally more than 10,000 yuan. Once the nozzle is blocked, the nozzle will be damaged. At present, the cleaning is mainly done by manual hand-held cleaning. After the experiment, it needs to be disassembled manually. , time-consuming and high labor costs. At the same time, the hand-held contact head cannot acc...

Problems solved by technology

After each experiment, it needs to be cleaned in time, otherwise it is easy to cause the spray liquid to remain in the nozzle and block the nozzle, so that it will not be able to spray normally when spraying next time

The cost of the micro-droplet nozzle is very high, generally more than 10,000 yuan. Once the nozzle is blocked, the nozzle will be damaged. At present, the cleaning is mainly done by manual hand-held cleaning. After the experiment, it needs to be disassembled manually. , time-consuming, high labor costs

At the same time, the hand-held touch head cannot accurately calculate the draft of the nozzle. If it is too low, it will not be able to complete accurate cleaning. If it is too deep, the nozzle will be prone to water seepage, causing the circuit in the nozzle to be damaged and cannot be used normally.

[0003] On the other hand, after cleaning the droplet nozzles, most of them are dried naturally. The long drying process will easily affect the subsequent experiments.

At the same time, the micro-drop nozzle has high requirements on the environment, and the dust in the air has a great impact on it. If the drying time is too long, it may cause dust to accumulate on the nozzle and affect its normal use. The drying time is not easy to control

At present, there is no simple and efficient solution for the effective cleaning of droplet nozzles. For this reason, the inventor has designed a special device for cleaning the droplet nozzles.
