Take out the filter element 202 in the filter element placement pit 201 through the filter element conveying mechanism and transfer it to the filter element transfer platform 110, and transfer the filter element 202 at the filter element transfer platform 110.

[0045] It should be noted that in the above method, if the cover 203 is connected to the filter element placement pit 201 or related components by means of bolts, etc., the bolts can be tightened or loosened manually.

[0046] In one embodiment, in the above method, there are a plurality of filter element placement pits 201, and each filter element placement pit 201 is located below the guide rail 102. When removing the filter element 202 in one of the filter element placement pits 201, filter elements 202 are placed in the other filter element placement pits 201. In this way, during the removal and flipping of one filter element 202, the other filter elements 202 can be in a cleaning state. This is beneficial for making full use of time.

[0047] As Figure 1 and Figure 2 shown, an embodiment of the present application further provides a filter element picking and placing device, which includes a frame 101, a cover conveying mechanism, a filter element conveying mechanism, and a flipping mechanism 109.

[0048] A plurality of filter element placement pits 201 are provided at the frame 101. A cover storage platform 108 is provided at one end of the frame 101. A guide rail 102 is also provided on the frame 101, and the extending direction of the guide rail 102 is parallel to the length direction of the frame 101. The cover conveying mechanism can move along the guide rail 102, and the cover conveying mechanism is used to pick and place the cover 203 and move the cover 203 along the guide rail 102. The filter element conveyor can move along the guide rail 102, and the filter element 202 conveying mechanism is used to pick and place the filter element 202 and move the filter element 202 along the guide rail 102. The flipping mechanism is arranged outside the other end of the frame 101, and the flipping mechanism 109 is used to receive the filter element 202 conveyed by the filter element conveying mechanism and flip the filter element 202 by 180 degrees.

[0049] In one embodiment, as Figure 1 shown, a filter element transfer platform 110 is provided on one side of the flipping mechanism. The above filter element transfer platform 110 is used to place the filter element 202.

[0050] In one embodiment, as Figure 2 and Figure 3As shown, the cover conveying mechanism includes a conveying component 103 that cooperates with the guide rail 102. A first lifting component 104 is installed on the conveying component 103, and a cover picking component 106 is arranged on the first lifting component 104. The cover picking component 106 includes a first platform 1061. A number of support bearings are arranged on the first platform 1061, and a rotating shaft 1063 is installed in each support bearing. The lower end of the rotating shaft 1063 is located below the first platform 1061. A hook 1064 is arranged at the lower end of the rotating shaft 1063, and each rotating shaft 1063 is respectively connected to a first synchronous belt drive component. Specifically, the first synchronous belt drive component is arranged on the first platform 1061. The first synchronous belt drive component includes a first drive motor 1062. A first drive wheel is installed on the first drive motor 1062. A synchronous wheel is arranged at the upper end of each rotating shaft 1063. A synchronous belt is connected between the first drive wheel and each synchronous wheel. A number of synchronous belt tensioning columns 1065 are also arranged on the first platform 1061. The above-mentioned first drive motor 1062 drives the first drive wheel to rotate. The first drive wheel drives each synchronous wheel to rotate through the synchronous belt, thereby causing each rotating shaft 1063 to rotate. The rotation of the rotating shaft 1063 can make the hook 1064 rotate to the hanging ring 204 on the cover 203. As Figure 1 shown in, 3 hanging rings 204 are arranged on the cover 203. When the first lifting component 104 rises, it can cause the entire cover picking component 106 to rise. The hook 1064 on the rotating shaft 1063 of the cover picking component 106 will hook the corresponding hanging ring 204, and then the cover 203 can be caused to rise through a plurality of hooks 1064. Then, the first lifting component 104, the cover picking component 106 and the cover 203 can be conveyed to the target position together through the conveying component 103. When it is necessary to lower the cover 203, the first lifting component 104 descends, and the first drive motor 1062 drives each rotating shaft 1063 to rotate, so that the hook 1064 is separated from the hanging ring 204 on the corresponding cover 203.

The conveying motor 1032 is installed on the conveying frame 1031, and the conveying wheel is also installed on the conveying frame 1031. Therefore, the rolling of the conveying wheel can drive the conveying frame 1031 to move along the guide rail 102 together. The rolling support 1033 can be composed of a support column 1033a and corresponding rolling elements 1033b. For example, the rolling element 1033b can be a rolling element such as a bearing.

The driving cylinder 1075 is connected to a pin 1074, and the pin 1074 is used to insert into the pin hole 1073. In the above-mentioned embodiment of the present application, both the filter element conveying mechanism and the cover body conveying mechanism are installed on the same conveying assembly 103. The slots on each insertion block 1072 are used for the upper ends of the longitudinal plates 2021 arranged on the filter element 202 to be inserted. Generally, a plurality of longitudinal plates 2021 are arranged on the filter element 202. Through holes are arranged at the upper ends of the above-mentioned longitudinal plates 2021. The above-mentioned pin 1074 moves back and forth under the drive of the driving cylinder 1075. When the pin 1074 sequentially passes through the pin hole 1073 and the through hole on the longitudinal plate 2021, the longitudinal plate 2021 is fixed to the insertion block 1072 by the pin 1074. In this way, the rise or fall of the second platform 1071 can drive the rise or fall of the filter element 202.
