Description

Technical Field

[0001] The present invention relates to the technical field, and specifically to a precision voice coil motor microdust treatment device. Background Art

[0002] At present, many manufacturers use the methods of water washing or compressed air to remove microdust from precision voice coil motors. This method can effectively remove the microdust on the surface of the motor, but for the internal microdust, only partial removal can be achieved.

[0003] Currently, the internal structure of the precision voice coil motor is complex, with many bends, shallow points, and a spring structure similar to a "valve". When using water washing, the dredging effect is not ideal, and the water flow cannot completely pass through. Moreover, when using water washing, the related drying and dehydration devices will cause related defects and increase the production cost and production efficiency. When using compressed air, the air flow cannot completely enter the internal structure either. Summary of the Invention

[0004] The purpose of the present invention is to provide a precision voice coil motor microdust treatment device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A precision voice coil motor microdust treatment device includes a precision voice coil motor body. An acoustic cavity is provided on the precision voice coil motor body. An upper cover is provided above the acoustic cavity. An air cavity is provided in the middle of the acoustic cavity. Impellers are provided around the air cavity. A microdust aggregation area is provided outside the impellers. A main compressed air pipeline is provided in the middle of the bottom of the acoustic cavity. The main compressed air pipeline is communicated with the acoustic cavity. A hub is provided at the bottom of the acoustic cavity. A bottom spring is connected to the hub.

[0006] Preferably, a reverse current device is provided at the top of the acoustic cavity. An air cavity is provided in the middle of the acoustic cavity. A magnet ring is provided in the microdust aggregation area inside the air cavity. A coil is provided outside the magnet ring. A five-hole blowing tray is provided below the bottom of the air cavity. A valve is provided below the five-hole blowing tray.

[0007] Preferably, secondary air outlet pipes are provided on both sides of the top of the main compressed air pipeline. The air outlet of the secondary air outlet pipe is at an angle of 50° with the vertical direction.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] Aiming at the defect that the existing precision voice coil motor dust removal device cannot completely remove dust, the present invention adopts the method of gas impact. In actual production, the gas pressure can be quickly started, the valve of the precision voice coil motor is opened through the gas pressure, and the number of gas channels of the device is increased in multiple directions and at multiple angles, so that it can penetrate into various bends and shallow points of the internal structure of the motor, thereby achieving the effect of dust treatment.
