Description

Technical Field

[0001] The utility model relates to the technical field of cleaning aluminum nitride ceramic substrates, in particular to an ultrasonic cleaning device for aluminum nitride ceramic substrates. Background Art

[0002] The principle of ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium - the cleaning solvent. The ultrasonic wave radiates forward in the cleaning liquid in a sparse and dense manner, causing the liquid to flow and generate tens of thousands of tiny bubbles with a diameter of 50-500μm. The tiny bubbles in the liquid vibrate under the action of the sound field. These bubbles are formed and grow in the negative pressure area of ​​the longitudinal propagation of ultrasonic waves. In the positive pressure area, when the sound pressure reaches a certain value, the bubbles increase rapidly and then suddenly close, and a shock wave is generated when the bubbles close, generating thousands of atmospheres of pressure around them, destroying insoluble dirt and dispersing them in the cleaning liquid. When the group particles are wrapped in oil and adhere to the surface of the cleaning parts, the oil is emulsified and the solid particles are separated, thereby achieving the purpose of purifying the cleaning parts.

[0003] At present, there are still some defects in the use of ultrasonic cleaning devices for aluminum nitride ceramic substrates. For example, the aluminum nitride ceramic substrates need to be manually fished out one by one after cleaning. At the same time, a lot of time is needed to let the aluminum nitride ceramic substrates stand and dry after cleaning, which is time-consuming and labor-intensive to use. Therefore, an ultrasonic cleaning device for aluminum nitride ceramic substrates is proposed to solve the above-mentioned technical problems. Utility Model Content
