[0038] Example

[0039] This embodiment provides a variable frequency cleaning device, such as Figure 1 and Figure 2As shown, it includes: a base frame 1, a cleaning structure 2 and a detection control structure (not shown in the figure); wherein, the cleaning structure 2 includes a cleaning pool 21 and a driving member 22, the detection control structure includes a detection unit and a control unit, the base frame 1 is a frame composed of a plurality of rods, and the workpiece to be cleaned in this embodiment is a 3D printed model; before cleaning the workpiece, it is necessary to perform surface detection on the workpiece through the detection unit, and the surface parameters of the workpiece to be cleaned in the past, the detection unit can be specifically a surface cleanliness tester, and the surface cleanliness of the workpiece is detected by the surface cleanliness tester, and the surface parameters are surface cleanliness parameters; the control unit is a chip processing unit, and the control unit can flexibly configure the working frequency according to actual conditions, and the working frequency range is 20-40K. Specifically, for example, when the surface cleanliness of the workpiece is within a preset range, the control unit controls the driving member 22 to work at a normal frequency of 28k, and when the surface cleanliness is lower than the preset value, the driving member 22 is controlled to work at a working frequency lower than 28k, and the cleaning time can be reduced; when the surface cleanliness is higher than the preset value, the driving member 22 is controlled to work at a working frequency higher than 28K, and the cleaning time is extended.

[0040] Specifically, Figure 1 and Figure 2 As shown, a cleaning chamber is provided in the cleaning pool 21, and the cleaning chamber opens upward. The driving member 22 is an ultrasonic transducer. When cleaning the workpiece, a cleaning agent is first placed in the cleaning chamber, and the cleaning agent can be alcohol. Then the workpiece to be cleaned is placed in the cleaning chamber, and the control unit controls the driving member 22 to work, driving the cleaning agent in the cleaning chamber to vibrate to clean the surface of the workpiece to be cleaned. Through the above settings, different working modes are adopted for different workpieces, and a relatively clean workpiece is cleaned for a short time using a lower working frequency, and a relatively dirty workpiece is cleaned for a long time using a higher frequency, so that the workpiece with many surface undulations and dead corners can be cleaned. This not only improves the cleaning efficiency, but also reduces energy loss.

[0041] Specifically, Figure 1 and Figure 2 As shown, the base frame 1 is also installed with a first supporting platform 11, a second supporting platform 12 and a third supporting platform 13 from top to bottom; the first supporting platform 11, the variable frequency cleaning device also includes: a filtering structure 3 and a liquid storage structure 4; the liquid storage structure 4 is installed on the first supporting platform 11, the cleaning structure 2 is installed on the second supporting platform 12, and the filtering structure 3 is installed on the third supporting platform 13; ensure that the liquid storage structure 4, the cleaning structure 2 and the filtering structure 3 are placed from top to bottom.

[0042] Among them, Figure 1 and Figure 2As shown, the filtering structure 3 includes a first filter element 31 and a second filter element 32, which are symmetrically arranged on the third supporting platform 13, and the first filter element 31 and the second filter element 32 are both connected to the cleaning tank 21 through a pipeline; the liquid storage structure 4 includes a first liquid storage element 41 and a second liquid storage element 42, and the first liquid storage element 41 and the second liquid storage element 42 are both connected to the cleaning tank 21 through a pipeline, and the first liquid storage element 41 is also connected to the first filter element 31 through a pipeline, and the second liquid storage element 42 is also connected to the second filter element 32 through a pipeline; the variable frequency cleaning device also includes an opening and closing structure, which includes a first opening and closing member, which is arranged on the pipeline between the first liquid storage element 41 and the cleaning tank 21, and the first opening and closing member is also arranged on the pipeline between the second liquid storage element 42 and the cleaning tank 21; the opening and closing structure also includes a second opening and closing member, which is arranged on the pipeline between the cleaning tank 21 and the first filter element 31; the second opening and closing member is also arranged on the pipeline between the cleaning tank 21 and the second filter element 32.

[0043] The variable frequency cleaning device in this embodiment needs to be cleaned twice during cleaning. When cleaning the workpiece, the first cleaning is performed in the cleaning tank. During the first cleaning (rough cleaning), the two second opening and closing parts on the pipeline between the cleaning tank 21 and the filter structure 3 are closed. After the first cleaning is completed, the second opening and closing part between the cleaning tank 21 and the first filter element 31 is opened to discharge the cleaning liquid in the cleaning tank 21 into the first filter element 31 for filtration. The cleaning agent that has been filtered is moved to the first liquid storage element 41 for recovery through an additional water pump. Then the workpiece is cleaned for the second time. During the second cleaning (fine cleaning), the two second opening and closing parts on the pipeline between the cleaning tank 21 and the filter structure 3 are closed. After the second cleaning is completed, the second opening and closing part between the cleaning tank 21 and the second filter element 32 is opened to discharge the cleaning liquid in the cleaning tank 21 into the second filter element 32 for filtration. The cleaning agent that has been filtered is moved to the second liquid storage element 42 for recovery through an additional water pump.

[0044] like Figure 1 and Figure 2 As shown, when the next workpiece is cleaned, during the first cleaning, the first opening and closing piece between the first liquid storage piece 41 and the cleaning tank 21 is opened, and the two second opening and closing pieces on the pipeline between the cleaning tank 21 and the filtering structure 3 are closed, and the workpiece is cleaned using the cleaning agent stored in the first liquid storage piece 41, and the above-mentioned filtering process is repeated after the cleaning is completed; during the second cleaning, the first opening and closing piece between the second liquid storage piece 42 and the cleaning tank 21 is opened, and the two second opening and closing pieces on the pipeline between the cleaning tank 21 and the filtering structure 3 are closed, and the workpiece is cleaned using the cleaning agent stored in the second liquid storage piece 42, and the above-mentioned filtering process is repeated after the cleaning is completed.

[0045] like Figure 1 and Figure 2 As shown, through the above process, the cleaning agent is reused, saving cleaning costs. And by setting up two sets of liquid storage parts and filter parts, the cleaning agents used for rough washing and fine washing in the cleaning process are distinguished, avoiding repeated contamination caused by mixing the two sets of cleaning agents, resulting in subsequent rough washing or fine washing failures, and also avoiding long-term contact between workers and cleaning agents.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning structure 2 also includes a cover plate 5, which is arranged at the open end of the cleaning tank 21 to prevent the ultrasonic transducer from vibrating the cleaning agent during the cleaning process and causing liquid splashing, thereby causing waste of the cleaning agent.

[0047] The working process of the variable frequency cleaning device provided in this embodiment is as follows:

[0048] Detection process: The detection unit is used to detect the surface cleanliness of the workpiece. When the detected data is less than the preset value, the drive member 22 is controlled to work for a shorter working time at a lower working frequency; when the detected data is greater than the preset value, the drive member 22 is controlled to work for a longer working time at a higher working frequency.

[0049] The first cleaning and recovery process: the two second opening and closing parts on the pipeline between the cleaning tank 21 and the filtering structure 3 are closed. After the first cleaning is completed, the second opening and closing part between the cleaning tank 21 and the first filter element 31 is opened to discharge the cleaning liquid in the cleaning tank 21 into the first filter element 31 for filtration. The filtered cleaning agent is moved to the first liquid storage element 41 for recovery through an additional water pump.

[0050] The second cleaning and recovery process: the two second opening and closing parts on the pipeline between the cleaning tank 21 and the filtering structure 3 are closed. After the second cleaning is completed, the second opening and closing part between the cleaning tank 21 and the second filter element 32 is opened to discharge the cleaning liquid in the cleaning tank 21 into the second filter element 32 for filtration. The filtered cleaning agent is moved to the second liquid storage element 42 for recovery through an additional water pump.

[0051] Repeat the above steps for the next workpiece to be cleaned, which will not be described in detail here.

[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
