Generally, a plurality of stators 10 are stacked in the accommodating space. The up-down movement of the air knife 3 can clean the surfaces of the plurality of stators 10, and the reciprocating movement of the air knife 3 can repeatedly clean the surfaces of the stators 10 to improve the cleaning effect.

[0032] In the embodiment, the cleaning device comprises a mounting frame 6. As shown in Figures 5 to 7 , the air cover 2, the air knife 3, and the like are arranged on the mounting frame 6. In the embodiment, as shown in Figure 1 , the outer side of the mounting frame 6 is provided with a baffle 7 to play a protection role.

[0033] In the embodiment, the cleaning device comprises a first driving mechanism 22 for driving the air cover 2 to move up and down and a second driving mechanism 32 for driving the air knife 3 to move up and down. As shown in Figure 5 , Figure 6 , the first driving mechanism 22 is specifically a pneumatic cylinder, the extension rod of which is connected to the top of the air cover 2, and the air cover 2 is driven to move up and down by the extension rod extending and retracting. As shown in Figure 6 , Figure 7 , the second driving mechanism 32 is specifically a motor, the driving shaft of which is connected to a lifting plate 33, the lifting plate 33 is located above the top of the air cover 2, the air knife 3 is connected to the lifting plate 33 and can move up and down synchronously with the lifting plate 33. In other embodiments, the first driving mechanism 22 and the second driving mechanism 32 can adopt other mechanisms in the prior art which can drive the air cover 2 or the air knife 3 to move up and down.

[0034] In the embodiment, the cleaning device comprises a first guide rod 23 extending in the up-down direction, the first guide rod 23 is fixed to the top of the air cover 2 and extends upward from the top of the air cover 2, and the first guide rod 23 is arranged in sliding fit with the top of the mounting frame 6 to provide guidance for the up-down movement of the air cover 2. Specifically, two first driving mechanisms 22 are arranged, and two first guide rods 23 are arranged, the first driving mechanisms 22 are arranged at two opposite corners of the rectangle, and the two first guide rods 23 are arranged at the other two opposite corners of the rectangle to ensure the stability of the up-down movement of the air cover 2. In the embodiment, the lifting plate 33 is connected to the air knife 3 through a second guide rod 34, the second guide rod 34 comprises a plurality of rods arranged at intervals in the circumferential direction of the air knife 3, the second guide rod 34 extends in the up-down direction, and the second guide rod 34 extends downward from the lifting plate 33 into the air cover 2, the second guide rod 34 is arranged in sliding fit with the air cover 2 in the length direction, specifically, the second guide rod 34 is arranged in sliding fit with the top of the air cover 2 to provide guidance for the up-down movement of the air knife 3 relative to the air cover 2.

[0035] In the embodiment, as shown in Figure 4As shown, the carrier 100 comprises a support seat 120 for supporting the stator 10, the support seat 120 being arranged on the upper portion of the base 110. In this embodiment, the height of the support seat 120 is greater than the distance from the air outlet 31 of the air knife 3 to the bottom of the air knife 3, so as to ensure that the air knife 3 can blow to the bottom of the stator 10. In this embodiment, as shown in Figure 4 As shown, the carrier 100 further comprises a fixing assembly 130 for fixing the stator 10 stacked on the support seat 120, the fixing assembly 130 being fixed with the support seat 120.

[0036] In this embodiment, the air knife 3 is annular, and the air outlet 31 of the air knife 3 faces the inner side. When the stator cleaning device is in the working state, the air knife 3 surrounds the outer side of the stator 10 in the circumferential direction. During the cleaning operation, the air knife 3 blows inward at the air outlet 31 to clean the outer side of the stator 10, and then the air knife 3 moves up and down to perform up-down cleaning. The air knife 3 is arranged in an annular shape, so that the stator 10 can be cleaned at the same time, and the cleaning efficiency and effect can be improved.

[0037] In this embodiment, as shown in Figure 7 , Figure 8 As shown, the outer contour of the air knife 3 is circular, and the inner contour of the air knife 3 is shaped to match the cross section of the carrier 100 and the fixing assembly 130. In this embodiment, the cross section of the support seat 120 is smaller than the cross section of the fixing assembly 130 and the stator, so the inner contour of the air knife 3 matches the outer contour of the stator 10 and the fixing assembly 130 projected on the base 110. Specifically, the inner contour of the air knife 3 is similar to and enlarged in scale with the outer contour of the stator 10 and the fixing assembly 130 projected on the base 110, so as to ensure that the air knife 3 does not collide with the carrier 100 and the fixing assembly 130 when moving up and down, and the similar shape can shorten the distance between the air outlet 31 and the outer surface of the stator 10 to improve the cleaning effect. In other embodiments, the inner contour of the air knife 3 is similar to and enlarged in scale with the outer contour of the stator 10, the fixing assembly 130 and the support seat 120 projected on the base 110.

[0038] In this embodiment, the top of the air cover 2 is provided with an air outlet (not shown in the figure), and the air suction pipe 4 is connected with the air outlet. The air outlet is arranged at the top to avoid affecting the blowing cleaning operation of the air knife 3. Preferably, after the air cover 2 is lowered and abuts against the base 110, the first cleaning operation of the air knife 3 is performed from bottom to top, so that the dirt and the like generated in the first cleaning operation are sucked upward, and the cleaned stator 10 is located below, so as to reduce the secondary pollution to the cleaned stator 10. In this embodiment, the downward projection of the air outlet falls within the hollow region of the air knife 3, so that the dirt can be better gathered and sucked away.

[0039] In the embodiment, as shown in Figure 6 The bottom of the air cover 2 is provided with a sealing ring 21 made of elastic material, so as to improve the sealing effect between the bottom of the air cover 2 and the base 110 after abutting, thereby improving the effect of the air extractor to extract air outward. In the embodiment, the inner contour of the sealing ring 21 is similar to the outer contour shape of the stator 10, the fixing assembly 130 and the support seat 120 projected on the base 110, and has an enlarged scale.

[0040] In the embodiment, the transmission path of the carrier 100 is provided with a cleaning station 200, and the air cover 2 is arranged above the cleaning station 200. When the carrier 100 carrying the stator 10 moves to the cleaning station 200, the air cover 2 moves downward and abuts against the base 110 at the cleaning station 200, and the cleaning work starts. In the embodiment, the cleaning station 200 is provided with a stopping member 210, and the carrier 100 is accurately stopped at the cleaning station 200 by the stopping member 210. Specifically, as shown in Figure 1 、 Figure 2 The stopping member 210 is arranged at the front side of the cleaning station 200 in the transmission direction. In the embodiment, the stopping member 210 is arranged to be able to ascend and descend, and when the stopping member 210 rises upward, it blocks the transmission path of the carrier 100 forward, thereby stopping the carrier 100 at the cleaning station 200. When the stopping member 210 moves downward, it exits the transmission path of the carrier 100, and the carrier 100 can continue to transmit forward.

[0041] In the embodiment, the transmission path of the carrier 100 is provided with a jacking mechanism 5, and the jacking mechanism 5 includes a jacking seat 51 capable of ascending and descending, and the jacking seat 51 is located below the air cover 2. Specifically, the jacking seat 51 is arranged at the cleaning station 200, and the jacking seat 51 is used to jack up the carrier 100 moving to the cleaning station 200 upward, so that the carrier 100 is separated from the transmission mechanism 1, avoiding damage to the transmission mechanism 1 in the process of pressing the air cover 2 downward, and the jacking seat 51 provides stable support for the carrier 100.

[0042] In the embodiment, the transmission mechanism 1 includes two guide rails 11 arranged in parallel, and when the carrier 100 is transmitted, the carrier 100 is arranged on the two guide rails 11, and the guide rails 11 provide guidance for the carrier 100 and realize the transmission of the carrier 100. Specifically, the guide rails 11 are provided with a conveying belt for transmitting the carrier 100. The jacking seat 51 and the stopping member 210 are arranged between the two guide rails 11, respectively.

[0043] In the embodiment, as shown in Figure 2 、 Figure 3As shown, the mounting frame 6 is erected above the guide rail 11, and the mounting frame 6 is formed with an entrance and exit for the carrier 100 to enter and exit the cleaning station 200. In the embodiment, detection gratings 8 are arranged on both sides of the cleaning station 200 along the transmission direction of the carrier 100, so as to avoid the body of a person from mistakenly entering the cleaning station 200 when the cleaning work is being performed, thereby avoiding safety hazards. Specifically, referring to Figure 3 , Figure 6 As shown, the detection gratings 8 are arranged at the entrance and exit of the mounting frame 6 into the cleaning station 200, and detection gratings 8 are arranged on both sides of the entrance and exit.

[0044] In the embodiment, the stator cleaning device comprises a pressure regulating valve 91, which is signal-controlled with the air knife 3, and an operator can adjust the air blowing pressure of the air knife 3 through the pressure regulating valve 91.

[0045] In the embodiment, the stator cleaning device comprises a control panel 92, which is signal-connected with the transmission mechanism 1, the first driving mechanism 22, the second driving mechanism 32, the air knife 3, the pressure regulating valve 91, etc., and an operator can adjust the cleaning device through the control panel 92. In some embodiments, the control panel 92 is also signal-connected with the jacking mechanism 5 and the stop piece 210, and can adjust the jacking mechanism 5 and the stop piece 210. In the embodiment, the stator cleaning device further comprises a control electric box 93 for controlling the power supply.

[0046] In summary, when the carrier 100 carrying the stator 10 moves to the cleaning station 200, the stop piece 210 prevents the carrier 100 from continuing to move forward, and the jacking seat 51 jacks up the carrier 100 upward. Then the air cover 2 moves downward and abuts against the base 110 of the carrier 100, so as to form a closed space between the air cover 2 and the base 110, and the stator 10 is located in the closed space. At this time, the air knife 3 located in the air cover 2 is driven to move up and down to clean the surface of the stator 10, and the dust and other dirty things generated in the cleaning process are sucked out through the air extractor, so as to avoid secondary pollution. The cleaning device has simple structure and simple operation, and good cleaning effect can be obtained through synchronous blowing and suction.
