Description

Technical Field

[0001] This application relates to the field of camera device technology, and more specifically, to an ultrasonic vibration cleaning device. Background Technology

[0002] With the rapid development of industries such as precision manufacturing, medical devices, microelectronics, and optical components, the requirements for the cleanliness of parts surfaces are becoming increasingly stringent. Traditional cleaning methods (such as spraying, brushing, and chemical immersion) have significant limitations in removing micron- and even nano-sized particles, grease, and organic residues: on the one hand, mechanical contact can easily damage the surface of high-value workpieces; on the other hand, the use of chemical solvents poses environmental and safety risks.

[0003] A search revealed that Chinese patent CN221133442U discloses a camera cleaning device, a camera, and a vehicle. This technical solution adjusts the size of the piezoelectric ceramic ring by adjusting the number of stacked ceramic rings, thus making the piezoelectric ceramic ring suitable for different application scenarios.

[0004] In the above technical solution, although multiple stacked ceramic rings can achieve different amplitude and frequency responses, the stacked structure makes it difficult to dissipate internal heat. Furthermore, the difference in thermal expansion coefficients between the ceramic rings and the interlayer materials can lead to interlayer delamination under large temperature changes, affecting the output amplitude and frequency response of the piezoelectric ceramic rings. In view of this, we propose an ultrasonic vibration cleaning device. Utility Model Content

One side of the first conductive ring is connected and fixed to the conductive ring, and a plurality of first ceramic discs are fixedly installed on the other side. The opening of the installation cavity is sealed with epoxy sealant.

The epoxy sealant is coated on the surface of the circuit board. Multiple first ceramic discs are connected in parallel with each other.

[0014] 3. Beneficial effects Compared with the prior art, the beneficial effects of this application are: 1) By setting multiple first ceramic discs and second ceramic discs arranged in a ring, this application avoids the stacking of ceramic discs, increases the heat dissipation performance of ceramic discs, prevents the ceramic discs from peeling off from the conductive ring due to the difference in thermal expansion coefficients, and increases the reliability of the device.

[0015] 2) By staggering the spatial positions of the first ceramic disc and the second ceramic disc, this application enables the vibrations generated by the first ceramic disc and the second ceramic disc to act on the lens along different paths, thereby widening the amplitude and response frequency of the device.

[0017] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] Please see Figure 1 and Figure 2 This application provides an ultrasonic vibration cleaning device, including a housing 1, a lens 2, and a transmission ring 3. The housing 1 is sleeved on the outside of the transmission ring 3, and the lens 2 is clamped between the housing 1 and the transmission ring 3. An isolation tube 4 is provided in the middle of the transmission ring 3, and the end of the isolation tube 4 abuts against the surface of the lens 2. An installation cavity 5 is provided between the isolation tube 4 and the transmission ring 3. A first conductive ring 6 is provided in the installation cavity 5. One side of the first conductive ring 6 is connected and fixed to the transmission ring 3, and a plurality of first ceramic discs 7 are fixedly installed on the other side. The opening of the installation cavity 5 is sealed with epoxy sealant.

[0019] In this technical solution, multiple first ceramic discs 7 are distributed in a ring at equal intervals on the first conductive ring 6. The multiple first ceramic discs 7 can vibrate independently or synchronously to achieve different amplitudes and response frequencies. The vibration can be transmitted to the lens 2 through the first conductive ring 6 and the conductive ring 3 to clean the dirt on the lens 2.

[0020] In a preferred embodiment of this application, a circuit board 8 is provided inside the mounting cavity 5. The circuit board 8 is used to drive the first ceramic disc 7. A wire 9 is electrically connected to the circuit board 8 for connecting external devices. Epoxy sealant is applied to the surface of the circuit board 8. Multiple first ceramic discs 7 are connected in parallel. At least one first ceramic disc 7 has a switch connected in series at its positive terminal, and the switch is integrated on the circuit board 8. Multiple first ceramic discs 7 can be independently controlled by the on / off state of the switch to achieve different amplitudes and response frequencies. In the parallel connection state, damage to any one first ceramic disc 7 will not affect the normal operation of the other first ceramic discs 7.

[0021] In a preferred embodiment of this application, a second conductive ring 10 is provided inside the mounting cavity 5. One side of the second conductive ring 10 is connected and fixed to the conductive ring 3, and a plurality of second ceramic discs 11 are fixedly mounted on the other side. By setting the first ceramic discs 7 and the second ceramic discs 11, the range of amplitude and response frequency of this device can be expanded, making it suitable for cleaning various types of dirt.

[0022] Preferably, both the first conductive ring 6 and the second conductive ring 10 are made of copper, the outer shell 1 is made of plastic, the conductive ring 3 is made of stainless steel, and the isolation tube 4 is made of nylon. The second conductive ring 10 is positioned above the first conductive ring 6. The first conductive ring 6 has eight first ceramic discs 7, and the second conductive ring 10 has six second ceramic discs 11. By activating three second ceramic discs 11, the output amplitude is 1.5-2μm, which can achieve low-power cleaning to remove dry dust from the lens 2. By activating six second ceramic discs 11, the output amplitude is 3-14μm, which can remove water film from the lens 2. By activating eight first ceramic discs 7 and six second ceramic discs 11, the output amplitude is 15-30μm, which can remove stubborn dirt.

[0023] As a preferred embodiment of this application, the orthographic projection of the first ceramic disc 7 onto the lens 2 falls on the lens 2, the inner diameter of the second conductive ring 10 is larger than the inner diameter of the first conductive ring 6, and the orthographic projection of the second ceramic disc 11 onto the lens 2 falls on the lens 2, so that vibration can be effectively transmitted to the lens 2.
