Description

Blending ultrasonic drive control micro-droplet cluster cleaning system

Technical Field

The utility model relates to a surface treatment field, specificly relate to a little liquid drop cluster cleaning system of blending ultrasonic drive control.

Background

For cleaning of delicate surfaces, both the dirt needs to be cleaned with high efficiency and the surface cannot be damaged, so the choice of "brush" is very critical. The term "brush" is used herein to mean a system of contacts that act on the surface being treated.

The following are some of the alternatives that may be selected,

(1) soft media such as dust-free cloth: the method is adopted by many factories at present, cleaning is realized by means of dust-free cloth and mechanical contacts on the surface, and the requirement of supporting facilities is lowest. Its disadvantages are no tissue discharge of cleaning agent, harm to environment and health, high labor consumption, and no cleaning of dirt in the surface of the cleaning agent.

(2) Static ultrasonic liquid soaking: the cleaning surface is immersed in an ultrasonic water bath and cleaning is achieved by the contact of the liquid and the solid at the interface. The method has wide application and low cost. But on one hand, the method has larger waste water discharge amount, on the other hand, the method is offline centralized cleaning and is difficult to integrate into a high-speed intelligent production line, and the method deviates from the current green and intelligent development direction.

(3) High velocity water or steam jet: it is also a common method to achieve cleaning by means of jets and contact points on the surface. The matching setting requirement is low, and the cost is not high. The defects are that the cleaning effect is insufficient, and the conditions of splashing and the like are difficult to treat on an automatic production line.

(4) Dry ice blasting: the cleaning is achieved by carrying several millimeters of dry ice particles against the surface by a high velocity air stream, using dry ice impact contacts and freezing effects. This method works well for cleaning large parts, but risks damage to surfaces with surface fine structures, and is inherently associated with high costs.

(5) Laser: the surface is scanned with a laser beam of suitable energy, and the smudge is vaporized by the thermal contact of the laser with the surface. The disadvantages are high system complexity, high cost and certain damage to the substrate.

In addition to extensive applications such as surface cleaning, sterilization, skin lesion application and the like, an intelligent flexible adjustable contact system is required on a corresponding surface to be treated, but the currently adopted modes and methods are difficult to realize powerful dead-angle-free cleaning of the surface to be treated and powerful energy transmission in a low-cost mode, and have the effects of adapting to surfaces of different types and shapes, flexible and adjustable cleaning energy, no damage to the surface and the like, so that a system capable of simultaneously solving or solving a part of the problems is required to be found.

Comparison of experiments

(1) Removal of finger prints from glass

The fingerprint is pressed on the glass of the mobile phone, and the difference of the cleaning effect of the pure water vapor jet contact system and the ultrasonic micro-droplet cluster contact system on the fingerprint is compared. In both experiments, the mass flow of steam was 5 g/min, the jet velocity was 30m/s, the distance from the treated surface was 60 mm, and the treatment time was 20 s. In the steam jet experiment, the steam temperature is 95 ℃, 150 ℃ and 230 ℃, respectively, while in the ultrasonic micro-droplet experiment, the steam temperature is 95 ℃, the ultrasonic frequency is 28K, and the power can be adjusted from 0-40W.

First, in two experiments, microdrop contacts were formed on cold cell phone glass, and apparently, as time increased, the ultrasonic microdrop contacts were more easily connected to form a film and spread. More importantly, the finger print still exists obviously after the pure steam jet contact is adopted due to the fact that the jet speed is low. And when the ultrasonic micro-droplet clusters are applied, the fingerprints completely disappear. Extremely fine oil was observed on the latter droplets, indicating that the contact was able to oscillate the fingerprint into a microemulsion-like state.

In order to further increase the difficulty of the experiment, the surface to be treated is changed into a workpiece which is just machined, and a micro-droplet cluster contact system is adopted. The results show that the contact can not only treat the dirt, but also remove the scale on the surface of the workpiece when the ultrasonic power reaches 40W, and no leak point is found in the cleaning.
