[0035] Current ultrasonic dust removal equipment generally uses high-speed and high-pressure airflow to pass through an ultrasonic generating chamber, and expands the airflow multiple times to produce an ultrasonic oscillating airflow. However, this method has high requirements for airflow rate and wind pressure, so it needs to be equipped with a high-pressure, high-flow fan, resulting in a complex equipment structure and high manufacturing cost.
[0036] To this end, the utility model proposes a dust removal device 10, comprising:
[0037] The housing 100 has a mounting surface, and the mounting surface is arranged opposite to the product 20 to be dusted;
[0038] A piezoelectric ceramic transducer is disposed on the mounting surface, and the piezoelectric ceramic transducer generates ultrasonic waves toward the product 20 to be dusted; and
[0039] The dust extraction component 300 is arranged on the installation surface, and the dust extraction component 300 is used to extract dust from the product 20 to be dust-removed.
[0040] Compared with the prior art, in the technical solution of the utility model, the dust removal device 10 includes a housing 100, and a mounting surface is provided on the housing 100, and the mounting surface is opposite to the position of the product 20 to be dusted. A piezoelectric ceramic transducer is provided on the mounting surface. By applying an electric field to the piezoelectric ceramic transducer, the piezoelectric ceramic transducer can generate ultrasonic waves toward one side of the product 20 to be dusted, and the ultrasonic waves can vibrate the product 20 to be dusted, so that the dust leaves the surface of the product 20 to be dusted; in addition, the dust removal device 10 also includes a dust extraction component 300, and the dust extraction component 300 is provided on the mounting surface. The dust extraction component 300 can extract the dust on the surface of the product 20 to be dusted, so as to realize the dust removal treatment of the product 20 to be dusted. In the technical solution, the generation of ultrasonic waves can be realized by utilizing the characteristic of the piezoelectric ceramic transducer that can convert mechanical energy and electrical energy into each other, and the dust removal of the product can be realized by using the dust extraction component 300, which has the advantage of simple structure and is also conducive to reducing the manufacturing cost of the dust removal equipment.
[0041] like Figure 2 In one embodiment of the present invention, the piezoelectric ceramic transducer is spaced apart from the product 20 to be dusted. The spaced apart arrangement of the piezoelectric ceramic transducer and the product 20 to be dusted can prevent the dust on the piezoelectric ceramic transducer or the mounting surface from adhering to the product 20 to be dusted, thereby preventing secondary contamination of the product 20 to be dusted.
[0042] In one embodiment of the utility model, the piezoelectric ceramic transducer includes a plurality of first piezoelectric ceramic sheets, and the plurality of first piezoelectric ceramic sheets are stacked. The first piezoelectric ceramic sheets can adopt a conventional piezoelectric ceramic power generation sheet structure on the market, and the plurality of first piezoelectric ceramic sheets are bonded to each other, and all positive electrodes are connected, and all negative electrodes are connected, so that the plurality of first piezoelectric ceramic sheets can generate ultrasonic waves in phase, and after the plurality of first piezoelectric ceramic sheets are stacked, the ultrasonic waves generated by the plurality of first piezoelectric ceramic sheets can be superimposed, thereby increasing the amplitude of the ultrasonic wave acting on the product 20 to be dusted, and increasing the excitation effect on the product 20 to be dusted, thereby improving the dust removal effect.
[0043] In one embodiment of the utility model, the piezoelectric ceramic transducer includes a plurality of second piezoelectric ceramic sheets, which are arranged side by side and spliced with each other. The piezoelectric ceramic transducer may include a plurality of second piezoelectric ceramic sheets, which may be the same as the first piezoelectric ceramic sheets, and both may adopt conventional piezoelectric ceramic power generation sheets on the market. The plurality of second piezoelectric ceramic sheets are arranged side by side and spliced with each other, so that the piezoelectric ceramic transducer can generate ultrasonic waves with a wider range, thereby increasing the dust removal area of the dust removal product 20 to be dusted, which is conducive to meeting the dust removal requirements of large-sized dust removal products 20 and improving the dust removal efficiency.
[0044] like Figure 2 In one embodiment of the present utility model, the dust extraction assembly 300 includes:
[0045] The negative pressure chamber 310 is provided on the housing 100;
[0046] The air suction port 320 is disposed on the mounting surface and communicated with the negative pressure chamber 310 .
[0047] In this embodiment, the negative pressure chamber 310 can be integrally formed inside the shell 100, and an interface can be provided on the shell 100 to communicate with the negative pressure chamber 310, and the interface can be connected to a device that generates negative pressure. In addition, an exhaust port 320 is provided on the mounting surface, and the exhaust port 320 is communicated with the negative pressure chamber 310. In this way, the dust shaken away from the product to be dusted 20 can be sucked into the negative pressure chamber 310 by the exhaust port 320 and discharged, thereby completing the purification of the product to be dusted 20 and preventing the dust from causing secondary contamination to the product to be dusted 20.
[0048] like Figure 2 In one embodiment of the present utility model, the dust extraction assembly 300 further includes:
[0049] A positive pressure chamber 330 is provided in the housing 100;
[0050] The air blowing port 340 is disposed on the mounting surface and communicated with the positive pressure chamber 330 .
[0051] In this embodiment, the positive pressure chamber 330 can be integrally formed inside the shell 100, and an interface can be provided on the shell 100 to communicate with the positive pressure chamber 330, and the interface can be connected to a device that generates positive pressure. In addition, an air blowing port 340 is provided on the mounting surface, and the air blowing port 340 is communicated with the positive pressure chamber 330. In this way, the dust that is shaken away from the product 20 to be dusted can be blown away from the area where the product 20 to be dusted has completed dust removal, thereby preventing the dust from causing secondary contamination of the product 20 to be dusted.
[0052] like Figure 2In one embodiment of the utility model, the blowing port 340 is tilted toward the product 20 to be dusted; and / or, the exhaust port 320 is tilted toward the product 20 to be dusted; and / or, the blowing port 340 and the exhaust port 320 are arranged on opposite sides of the piezoelectric ceramic transducer. In order to improve the dust removal effect, the blowing port 340 can be tilted toward the end face of the product 20 to be dusted, so that when the airflow blows to the end face of the product 20 to be dusted, it can apply a force parallel to the end face to the dust on the end face, so that the dust is easier to detach from the end face, thereby improving the dust removal effect; similarly, the exhaust port 320 can also be tilted toward the end face of the product 20 to be dusted, so that the dust can be more easily extracted from the end face of the product 20 to be dusted, which is also conducive to improving the dust removal effect. In addition, in another embodiment, the blowing port 340 and the exhaust port 320 can be arranged on opposite sides of the piezoelectric ceramic transducer. In this way, during the dust removal process, the piezoelectric ceramic transducer first allows the dust to be separated from the product to be dusted 20. After that, the blowing port 340 and the exhaust port 320 can simultaneously apply forces in the same direction to the dust, so that the dust moves in a specific direction to prevent secondary contamination of other parts of the product to be dusted 20. In addition, during the production process, the product to be dusted 20 can have a displacement from the exhaust port 320 to the blowing port 340 relative to the dust removal device 10. In this way, the dust can always be blown to the undusted area on the product to be dusted 20, which is also beneficial to prevent secondary contamination of the product to be dusted 20.
[0053] The utility model also proposes a dust removal device, which includes a device body and a dust removal device 10 arranged on the device body. The specific structure of the dust removal device 10 refers to the above embodiment. Since the dust removal device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0054] See also Figure 3 In one embodiment of the utility model, two dust removal devices 10 are provided, and the two dust removal devices 10 are arranged at intervals, and the installation surfaces of the two dust removal devices 10 are arranged opposite to each other. The two dust removal devices are arranged on opposite sides of the product 20 to be dusted. In this solution, the product 20 to be dusted can be a film material or a sheet material. The two dust removal devices are respectively opposite to the two opposite end faces of the product 20 to be dusted, and can respectively perform dust removal on the two opposite end faces of the product 20 to be dusted. In this way, the two opposite end faces of the product 20 to be dusted can be dusted at the same time, which improves the dust removal effect and also improves the efficiency of the dust removal work.
[0055] In one embodiment of the utility model, the ultrasonic waves generated by the piezoelectric ceramic transducers in the two dust removal devices 10 are in opposite phases. The ultrasonic waves generated by the two dust removal devices 10 are in opposite phases, so that the directions of the forces generated by the ultrasonic waves generated by the two dust removal devices 10 when acting on the product 20 to be dusted are the same, so that the oscillation force on the product 20 to be dusted can be increased, thereby increasing the amplitude of the product 20 to be dusted, and further improving the dust removal effect.
[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
