Description

Technical Field

[0001] The utility model relates to a piezoelectric ceramic sheet cleaning device, belonging to the technical field of piezoelectric ceramics. Background Art

[0002] Piezoelectric ceramics are an electronic sound-generating element. Piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric film will vibrate according to the size and frequency of the signal and produce corresponding sound.

[0003] During the production process of piezoelectric ceramic sheets, the surface of the piezoelectric ceramic sheets needs to be polished. After polishing, there will be some debris, dust and other impurities on the surface of the piezoelectric ceramic sheets. At this time, the surface of the piezoelectric ceramic sheets needs to be cleaned. The existing cleaning method is to place the piezoelectric ceramic sheets in a cleaning tank and then rinse the piezoelectric ceramic sheets. The above cleaning process requires continuous flushing of the surface of the piezoelectric ceramic sheets, but this cleaning method requires the use of a large amount of water, and it is also easy for the cleaned debris, dust and other impurities to re-adhere to the surface of the piezoelectric ceramic sheets, affecting the cleaning effect of the piezoelectric ceramic sheets.

[0004] In order to solve the above problems, technologies have also emerged in the industry, such as the Chinese authorized utility model patent with the authorization announcement number CN 213967939 U and the patent name: A piezoelectric ceramic sheet washing device. In the above patent, an overflow tank is set. When the piezoelectric ceramic sheet is in the cleaning process, the impurities washed out float on the top of the cleaning water, and then flow into the overflow tank through the cleaning water, thereby realizing the circulation of the cleaning water and reducing the amount of cleaning water used.

[0005] However, the following problems occurred during the actual use of the above technology:

[0006] 1. During the cleaning process of the piezoelectric ceramic sheet in the above patent, it is assumed that the impurities cleaned out float on the water surface, and then the impurities can be washed away with the water flow. However, in actual use, after the piezoelectric ceramic sheet is polished, the surface will be stained with fine particles of the piezoelectric ceramic sheet. These fine particles will dissolve in the cleaning water to form turbid water, which cannot be completely washed away with the water flow, causing the piezoelectric ceramic sheet to always be in turbid water and cannot be completely cleaned.

[0007] 2. During the cleaning process of the existing piezoelectric ceramic sheet, the piezoelectric ceramic sheet is fixed and is only cleaned by the flow of water, resulting in low efficiency of the cleaning process and poor cleaning effect.

[0008] 3. After cleaning, the surface of the existing piezoelectric ceramic sheet is relatively wet, and it needs to be blown dry separately after cleaning, which makes the entire processing process more cumbersome. Summary of the invention

DETAILED DESCRIPTION

[0030] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods:

[0031] like Figures 1 to 10 A piezoelectric ceramic sheet cleaning device is shown, comprising a box body 1 with an opening at the top, a vertical partition 101 is arranged in the middle of the box body 1, the vertical partition 101 divides the box body 1 into a cleaning box body 2 and a filtering box body 3, a piezoelectric ceramic sheet placement structure 4 is arranged inside the cleaning box body 2, a spray structure 5 is arranged on the top of the box body 1, a filter screen 301 is arranged inside the filtering box body 3, a support frame 6 is arranged at the bottom of the box body 1, and a dust removal adsorption structure 7 and a sewage extraction structure 8 are respectively arranged on the support frame 6.

[0032] like Figures 5 to 8 As shown, in order to fix the piezoelectric ceramic sheet, the piezoelectric ceramic sheet placement structure 4 further includes a roller 401, and the roller 401 is provided with a plurality of T-shaped slots 402 in the length direction, and T-shaped plug plates 403 are respectively provided in the T-shaped slots 402, and the T-shaped plug plates 403 are formed by bending a mesh plate, and a placement groove 404 is provided on the T-shaped plug plate 403, and a mesh cover plate 405 is also provided on the T-shaped plug plate 403.

[0033] like Figure 4 As shown, a rotating motor 406 is also provided on the side of the roller 401 . The rotating motor 406 is installed on the left side of the box body 1 through a motor frame 407 . The motor shaft of the rotating motor 406 passes through the box body 1 and is connected to the roller 401 .

[0034] like Figure 1As shown, in order to be able to pre-treat the piezoelectric ceramic sheet, a dust removal and adsorption structure 7 is set, and the dust removal and adsorption structure 7 includes an air pump 701 and a dust storage tank 702. One end of the air pump 701 is connected to the dust storage tank 702 through a first air pipe 703, and a second air pipe 704 is set at the other end of the air pump 701. The second air pipe 704 is inserted into the cleaning box 2.

[0035] like Figure 2 As shown, in order to achieve the circulation treatment of sewage, a sewage extraction structure 8 is set, and the sewage extraction structure 8 includes a sewage pump 801. A left pumping pipe 802 and a right pumping pipe 803 are respectively arranged on both sides of the sewage pump 801. The left pumping pipe 802 extends into the cleaning box 2, and the right pumping pipe 803 is inserted into the filtering box 3.

[0036] like Fig. 9 and Fig.10 As shown, a spray structure 5 is provided, and the spray structure 5 includes a spray seat plate 501 and an extraction seat plate 502. The spray seat plate 501 is installed on the top of the cleaning box 2, and the extraction seat plate 502 is installed on the top of the filtering box 3. The spray seat plate 501 is provided with a plurality of mounting through holes 503, and a nozzle 504 is provided at the bottom of the mounting through holes 503. A main water pipe 505 is provided on the upper part of the spray seat plate 501, and a plurality of branch water pipes 506 are provided on the main water pipe 505. The branch water pipes 506 are respectively inserted into the mounting through holes 503. A clean water pump 507 is provided on the extraction seat plate 502, and a first water pipe 508 is provided at one end of the clean water pump 507, and a second water pipe 509 is provided at the other end. The first water pipe 508 is also connected to the main water pipe 505, and the second water pipe 509 is inserted into the filtering box 3.

[0037] like Figure 3 As shown, a sewage discharge hole 302 is further provided at the inner bottom of the filter box 3 , and a drain valve 303 is provided on the sewage discharge hole 302 .

[0038] When in use, first insert the T-shaped plug plate 403 into the T-shaped slot 402 of the roller 401, then place the piezoelectric ceramic piece to be processed into the placement groove 404 of the T-shaped plug plate 403, and then cover the placement groove 404 with the mesh cover plate 405, so that the piezoelectric ceramic piece is fixed to the placement groove 404 through the mesh cover plate 405.

[0039] Then start the rotating motor 406, which drives the roller 401 to rotate, thereby also driving the piezoelectric ceramic piece to rotate, so that some dust and impurities attached to the piezoelectric ceramic piece will be separated from the piezoelectric ceramic piece due to centrifugal force and float in the cleaning box 2. At this time, start the vacuum pump 701, and the vacuum pump 701 sucks the dust and impurities in the cleaning box 2 into the dust storage tank 702. In this way, the piezoelectric ceramic piece is preliminarily processed, reducing the dust and impurities on the surface of the piezoelectric ceramic piece and reducing the difficulty of subsequent cleaning.

[0040] When the preliminary treatment is completed, the clean water pump 507 is started. The clean water pump 507 extracts the clean water from the filter box 3 through the second water pipe 509 and transports it to the main water pipe 505 through the first water pipe 508, and finally transports it to the water distribution pipe 506 through the main water pipe 505, and is sprayed out from the nozzle 504. The sprayed clean water sprays and cleans the piezoelectric ceramic piece. The surface of the piezoelectric ceramic piece can be cleaned by the pressurized spray water, so that the piezoelectric ceramic piece can be cleaned more effectively. At the same time, the cleaning by spraying solves the problem of the piezoelectric ceramic piece being immersed in muddy water and resulting in unclean cleaning in the prior art.

[0041] During the cleaning process, the sewage in the cleaning box 2 is pumped into the filter box 3 through the sewage pump 801. A filter screen 301 is arranged in the filter box 3. As the water level in the filter box 3 rises, the sewage at the bottom of the filter box 3 is filtered through the filter screen 301. At this time, the water located above the filter screen 301 is clean water that can be reused. The above method realizes the recycling of cleaning water.

[0042] When cleaning is completed, the rotating motor 406 continues to drive the piezoelectric ceramic piece to rotate, so that the piezoelectric ceramic piece can shake off the moisture on the surface when rotating to accelerate the drying of the surface of the piezoelectric ceramic piece. At the same time, the vacuum pump 701 is restarted. The vacuum pump 701 evacuates the cleaning box 2 through the second air pipe 704, so that the air in the cleaning box 2 flows faster. The fast-flowing air also accelerates the drying of the surface of the piezoelectric ceramic piece, thereby further improving the speed of drying the surface of the piezoelectric ceramic piece.

[0043] To summarize, by driving the piezoelectric ceramic piece to rotate through the rotating motor 406, the dust on the surface of the piezoelectric ceramic piece can be accelerated by centrifugal force to be thrown away, and at the same time, the dust removal and adsorption structure 7 is used to absorb the dust, thereby reducing the dust and impurities on the surface of the piezoelectric ceramic piece and reducing the difficulty of subsequent cleaning; the piezoelectric ceramic piece is sprayed and cleaned by the spray structure 5, and the piezoelectric ceramic piece is cleaned by pressurized cleaning water, which can not only rinse the impurities on the surface of the piezoelectric ceramic piece, but also keep the dirty water away from the piezoelectric ceramic piece after cleaning, thereby solving the problem that the piezoelectric ceramic in the existing cleaning device is always immersed in dirty water and causes unclean cleaning; at the same time, the piezoelectric ceramic piece is always in a rotating state during the spray cleaning process, which is also helpful for cleaning. After cleaning, the piezoelectric ceramic piece is also in a rotating state, which can quickly dry the water on the surface of the piezoelectric ceramic piece, thereby improving the cleaning efficiency.
