Description
Technical Field
The invention relates to the technical field of ultrasonic cleaning of lenses, in particular to an ultrasonic cleaning process for an optical lens.
Background
The optical glass lens is prepared by mixing oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and the like according to a specific formula, melting the mixture in a platinum crucible at a high temperature, uniformly stirring the mixture by using ultrasonic waves, and removing bubbles; and then slowly cooling for a long time to prevent the glass block from generating internal stress. And heating and forging the cooled glass block to form an optical lens blank, and then polishing to form the optical lens.
Ultrasonic waves propagate through the liquid, causing the liquid and the cleaning tank to vibrate together at an ultrasonic frequency, and the liquid and the cleaning tank have their own natural frequency when vibrating, and this vibration frequency is a sound wave frequency, so that people hear a buzzing sound. With the continuous development of the cleaning industry, more and more industries and enterprises use the ultrasonic cleaning machine.
In the principle of an ultrasonic cleaning machine, a high-frequency oscillation signal sent by an ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and is transmitted into a medium, namely a cleaning solvent, ultrasonic waves are radiated forwards at intervals in a cleaning liquid, the liquid flows to generate tens of thousands of micro-bubbles with the diameter of 50-500 mu m, and the micro-bubbles in the liquid vibrate under the action of a sound field. These bubbles are formed and grown in a negative pressure region where the ultrasonic wave propagates in the longitudinal direction, and in a positive pressure region, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. When the bubbles are closed, shock waves are generated, thousands of atmospheric pressures are generated around the bubbles, insoluble dirt is damaged, and the insoluble dirt is dispersed in the cleaning liquid, and when the group particles are wrapped by the oil dirt and adhered to the surface of a cleaning piece, the oil is emulsified, and solid particles are separated, so that the aim of cleaning the cleaning piece is fulfilled. In this process, known as the "cavitation" effect, the closing of the bubbles can create high temperatures of several hundred degrees and transient high pressures in excess of 1000 atmospheres.
The ultrasonic cleaning machine has the advantages that: the ultrasonic cleaning effect is good, and the operation is simple. The sound heard by people is a sound wave signal with the frequency of 20-20000Hz, the sound wave higher than 20000Hz is called ultrasonic wave, the transmission of the sound wave is longitudinally propagated according to a sine curve, and a large number of small bubbles are generated. One reason is that a tensile stress locally appears in the liquid to form a negative pressure, and the reduction of the pressure leads the gas originally dissolved in the liquid to be supersaturated and to escape from the liquid to be small bubbles; another reason is that strong tensile stresses "tear" the liquid into a void, known as cavitation.
Present optical lens can produce dirt such as dust, greasy dirt, sweat stain, fingerprint in the process of polishing, need wash the optical lens after polishing through ultrasonic cleaner, and there is following problem at the in-process that carries out ultrasonic cleaning at present optical lens: the clamping device of the optical lens cannot be adjusted according to the model size of the optical lens, and the surface of the optical lens is easily scratched when the optical lens is clamped, so that the optical lens is damaged; the optical lens cannot be turned over in the cleaning process, so that the cleaning is not thorough, and the cleaning effect of ultrasonic waves is reduced; the traditional cleaning operation is to place the lens in a cleaning machine for cleaning, then take out the cleaned lens and transfer the lens to a drying device, and the cleaning process is complicated, so that the cleaning flow is increased, and the cleaning efficiency of the optical lens is reduced.
