[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Please refer to the attached document. Figures 1-5 This application provides a suction cup assembly 100, which is applied to a photovoltaic cleaning robot and is used to adsorb or detach from the surface of a photovoltaic module.

[0037] Please refer to the attached document. Figures 1-5 In this embodiment, the suction cup assembly 100 includes a robot body 10, a suction cup module 20, and an air passage module 30. The robot body 10 has a housing 11, which has a receiving cavity 11a and a through hole 11b. The through hole 11b is opened in the lower side wall of the housing 11 and communicates with the receiving cavity 11a. The suction cup module 20 includes a mounting base 21, a lifting member 22, and a suction cup 23. The mounting base 21 is received in the receiving cavity 11a and connected to the housing 11. The lifting member 22 is vertically connected to the mounting base 21 and moves up and down in the vertical direction. The suction cup 23 is connected to the lower end of the lifting member 22 and is exposed on the outside of the housing 11. The suction cup 23 moves closer to or further away from the lower side wall of the housing 11 as the lifting member 22 moves relative to the mounting base 21. Used for adsorbing or detaching from the surface of photovoltaic modules; the gas path module 30 includes a pump body 31, a vacuum filter 32, and a pressure sensor 33; the pump body 31, vacuum filter 32, and pressure sensor 33 are all housed in the receiving cavity 11a, so that the pump body 31, vacuum filter 32, and pressure sensor 33 can make full use of the space of the receiving cavity 11a and avoid occupying the space of the outer wall of the housing 11; the pump body 31, vacuum filter 32, and suction cup 23 are connected in sequence to realize the adjustment of negative pressure or pressure relief of suction cup 23; the pressure sensor 33 is set between the pump body 31 and vacuum filter 32, which simplifies the gas path between the pump body 31, vacuum filter 32, suction cup 23, and pressure sensor 33 and improves the gas path adjustment efficiency of suction cup assembly 100.

[0038] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the robot body 10 is provided with a box 11, which is provided with a receiving cavity 11a and a through hole 11b. The through hole 11b is opened on the lower side wall of the box 11 and communicates with the receiving cavity 11a.

[0039] The suction cup module 20 includes a mounting base 21, a lifting member 22, and a suction cup 23. The mounting base 21 is housed in the receiving cavity 11a and connected to the housing 11. The lifting member 22 extends through the through hole 11b to the outside of the housing 11. The lifting member 22 is vertically connected to the mounting base 21 and can be raised and lowered in the vertical direction to adjust the height position of the lifting member 22. The suction cup 23 is connected to the lower end of the lifting member 22 and is exposed on the outside of the housing 11. The suction cup 23 moves closer to or further away from the lower side wall of the housing 11 as the lifting member 22 moves relative to the mounting base 21. The suction cup 23 is used to adsorb or detach from the surface of the photovoltaic module. When the suction cup 23 adsorbs the surface of the photovoltaic module, it ensures that the robot body 10 is stationary relative to the photovoltaic module. When the suction cup 23 detaches from the surface of the photovoltaic module, it allows the robot body 10 to move relative to the photovoltaic module.

[0040] The air path module 30 includes a pump body 31, a vacuum filter 32, and a pressure sensor 33. The pump body 31, vacuum filter 32, and pressure sensor 33 are all housed in the receiving cavity 11a, so that the pump body 31, vacuum filter 32, and pressure sensor 33 can make full use of the space of the receiving cavity 11a and avoid occupying the space of the outer wall of the housing 11. The pump body 31, vacuum filter 32, and suction cup 23 are connected in sequence to realize the adjustment of negative pressure or pressure relief of suction cup 23. The pressure sensor 33 is set between the pump body 31 and vacuum filter 32, which simplifies the air path between the pump body 31, vacuum filter 32, suction cup 23, and pressure sensor 33 and improves the air path adjustment efficiency of suction cup assembly 100.

[0041] Please refer to the attached document. Figure 5 In this embodiment, a first air pipe 34 is provided between the pump body 31 and the vacuum filter 32. Both ends of the first air pipe 34 are connected to the pump body 31 and the vacuum filter 32 respectively, achieving a connection between them. The first air pipe 34 is connected to a first connector, which in turn connects to a pressure sensor 33. This allows the pressure sensor 33 to be positioned between the pump body 31 and the vacuum filter 32, and the pressure sensor 33 is used to detect the air pressure coefficient of the first air pipe 34.

[0042] Please refer to the attached document. Figure 5 In this embodiment, a second air pipe 35 is provided between the vacuum filter 32 and the suction cup 23. The second air pipe 35 connects the vacuum filter 32 and the suction cup 23, so that the vacuum filter 32 can be connected to the suction cup 23 through the second air pipe 35, ensuring the communication effect between the vacuum filter 32 and the suction cup 23. The vacuum filter 32 is used to filter the gas flowing to the suction cup 23 through the second air pipe 35, so that the gas with impurities can be discharged towards the photovoltaic module through the suction cup 23. The adsorption end of the suction cup 23 is located at the bottom of the housing 11, so that the suction cup 23 can adsorb the photovoltaic module from top to bottom.

[0043] Please refer to the attached document. Figure 5In this embodiment, the gas path module 30 further includes a first exhaust section 36. The first exhaust section 36 is connected to a first gas pipe 34 via a third gas pipe 37, and then sequentially connected to a vacuum filter 32 and a suction cup 23 via the first gas pipe 34. This allows the gas adsorbed by the suction cup 23 to flow sequentially through the first gas pipe 34 and the third gas pipe 37 to the first exhaust section 36, thereby facilitating the exhaust of gas by the first exhaust section 36. The third gas pipe 37 is connected to a first valve body, which controls the gas flow rate of the third gas pipe 37. The first valve body is a two-position three-way valve. When the two-position three-way valve is closed, the inlet and outlet are connected, and gas cannot flow out through the outlet of the first valve body. Conversely, when the two-position three-way valve is open, the inlet and outlet are connected, and gas can flow from the inlet through the first valve body to the outlet.

[0044] Please refer to the attached document. Figure 5 In this embodiment, the gas path module 30 further includes a second exhaust section 38, which is disposed on one side of the first exhaust section 36. The second exhaust section 38 is connected to the pump body 31 through a fourth air pipe 381, so that the second exhaust section 38 can be connected to the pump body 31 through the fourth air pipe 381, ensuring the communication effect between the second exhaust section 38 and the pump body 31, thereby facilitating the flow of gas from the pump body 31 to the second exhaust section 38 through the fourth air pipe 381. This allows the second exhaust section 38 to discharge gas from the pump body 31.

[0045] Please refer to the attached document. Figures 1-4 In this embodiment, the gas path module 30 further includes a support member 39, which is housed in the receiving cavity 11a and connected to the housing 11. The support member 39 supports the pump body 31, the vacuum filter 32, and the pressure sensor 33, so that the housing 11 can support the pump body 31, the vacuum filter 32, and the pressure sensor 33 through the support member 39, thereby ensuring the positional accuracy of the pump body 31, the vacuum filter 32, and the pressure sensor 33 relative to the housing 11.

[0046] Please refer to the attached document. Figures 1-4 In this embodiment, the suction cup module 20 further includes a power component 24, which is connected to the lifting component 22 and drives the lifting component 22 to move up and down in the vertical direction, so that the lifting component 22 can achieve automatic lifting under the driving action of the power component 24. The support component 39 is provided with multiple support areas. The pump body 31 and the vacuum filter 32 are located in the same support area, and the power component 24 is located in another support area and installed on the support component 39, so that the pump body 31, the vacuum filter 32 and the power component 24 can make full use of the space of the support component 39 and avoid mutual interference between the pump body 31, the vacuum filter 32 and the power component 24.

[0047] Please refer to the attached document. Figures 1-4In this embodiment, the suction cup module 20 further includes a linkage module 25, which is located between the power component 24 and the lifting component 22. One end of the linkage module 25 is connected to the power end of the power component 24, and the other end is connected to the lifting component 22, so that the power component 24 can drive the lifting component 22 to move up and down via the linkage module 25, thereby facilitating the adjustment of the height position of the lifting component 22.

[0048] Please refer to the attached document. Figures 1-4 In this embodiment, the lifting member 22 is sleeved on the mounting base 21 and is vertically connected to the mounting base 21. The mounting base 21 is cylindrical, and the lifting member 22 is located inside the mounting base 21 and passes through the mounting base 21 so that the lifting member 22 can make full use of the internal space of the mounting base 21, thereby making it easier for the outer surface of the mounting base 21 to cover the lifting member 22 and improving the aesthetics of the suction cup assembly 100.
