[0060] The following specific embodiments are exemplary and non-limiting, and are intended to provide a basic understanding of the present application, and are not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.

[0061] When a component is considered to be “provided on” another component, it can be directly provided on the other component or there may be a component in between. When a component is considered to be “connected to” another component, it can be directly connected to the other component or there may be a component in between.

[0062] It can be understood that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular or equal to each other between the two components. For example, in combination with numerical descriptions, perpendicularity can refer to the angle between two straight lines being between 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being between 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0063] Unless otherwise defined, when the term "plurality" is used to describe the number of components, it specifically means that the components are two or more.

[0064] An embodiment of the present application provides a cleaning device for cleaning a suction nozzle, comprising a fixed seat and a cleaning mechanism. The fixed seat comprises a top wall, and the top wall is provided with an opening. The cleaning mechanism comprises a lifting member, a rotating power member and a cleaning member, wherein the lifting member is fixed in the fixed seat, the rotating power member is connected to the lifting member, and the cleaning member is connected to the rotating power member. The lifting member is used to drive the rotating power member to rise, so that the cleaning member extends out of the opening and extends into the suction nozzle, and the rotating power member is used to drive the cleaning member to rotate to clean the suction nozzle. The cleaning member is driven by the lifting member to extend into the suction nozzle, and the rotating power member drives the cleaning member to rotate to clean the inner wall of the suction nozzle, thereby reducing the steps of disassembling and assembling the suction nozzle, realizing fully automatic cleaning, and improving cleaning efficiency. Moreover, the lifting member, the rotating power member and the cleaning member cooperate to perform cleaning, which can reduce the interference of human factors, make the cleaning force more stable, and reduce damage to the suction nozzle.

[0065] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0066] See also Figure 1 , Figure 2 and Figure 4 In one embodiment of the present application, a cleaning device 100 is provided for cleaning a suction nozzle 200. The suction nozzle 200 is installed on a machine platform (not shown). The machine platform is provided with a moving part, and the moving part is connected to the suction nozzle 200, which can drive the suction nozzle 200 to move in a three-dimensional space.

[0067] The cleaning device 100 includes a fixed seat 10 and a cleaning mechanism 20. The fixed seat 10 includes a top wall 11, and the top wall 11 is provided with an opening 111. The cleaning mechanism 20 includes a lifting member 21, a rotating power member 22 and a cleaning member 23. The lifting member 21 is fixed in the fixed seat 10, the rotating power member 22 is connected to the lifting member 21, and the cleaning member 23 is connected to the rotating power member 22. The lifting member 21 is used to drive the rotating power member 22 to rise, so that the cleaning member 23 extends out of the opening 111 and extends into the suction nozzle 200, and the rotating power member 22 is used to drive the cleaning member 23 to rotate to clean the suction nozzle 200.

[0068] In the present application, the lifting member 21 drives the cleaning member 23 to extend into the suction nozzle 200, and the rotating power member 22 drives the cleaning member 23 to rotate, so as to clean the inner wall of the suction nozzle 200, thereby reducing the steps of disassembling and assembling the suction nozzle 200, realizing fully automatic cleaning, and improving the cleaning efficiency. In addition, the lifting member 21, the rotating power member 22 and the cleaning member 23 cooperate to perform cleaning, which can reduce the interference of human factors, make the cleaning force more stable, and reduce the damage to the suction nozzle 200.

[0069] In some embodiments, the fixing base 10 includes a side wall 12, and the top wall 11 is connected to the side wall 12. The side wall 12 includes a first side wall 121, a second side wall 122, a third side wall 123, and a fourth side wall 124. The first side wall 121 and the second side wall 122 are arranged along a first direction X, and the third side wall 123 and the fourth side wall 124 are arranged along a second direction Y. The first direction X is perpendicular to the second direction Y. The first side wall 121 connects the third side wall 123 and the fourth side wall 124, and the second side wall 122 connects the third side wall 123 and the fourth side wall 124. The top wall 11 connects the first side wall 121, the second side wall 122, the third side wall 123, and the fourth side wall 124, and forms an accommodating chamber 10a, and the cleaning mechanism 20 is disposed in the accommodating chamber 10a.

[0070] In some embodiments, the fixing base 10 is fixed to the machine platform through the third side wall 123 and the fourth side wall 124 .

[0071] See also Figures 1 to 3 In some embodiments, the lifting member 21 includes a lifting drive member 211, a connecting plate 212 and a slide rail 213. The lifting drive member 211 is fixedly connected to the first side wall 121. The slide rail 213 is provided on one side of the lifting drive member 211 and is fixedly connected to the first side wall 121. The connecting plate 212 connects the lifting drive member 211 and the slide rail 213. The rotating power member 22 is fixedly connected to the connecting plate 212. The lifting drive member 211 is configured to drive the connecting plate 212 to slide relative to the slide rail 213 along the third direction Z, thereby lifting the rotating power member 22, so that the cleaning member 23 extends out of the opening 111 and extends into the suction nozzle 200. The lifting drive member 211 is configured to drive the connecting plate 212 to slide relative to the slide rail 213 in the direction opposite to the third direction Z, thereby lowering the rotating power member 22, and withdrawing the cleaning member 23 from the suction nozzle 200 and retracting it into the accommodating chamber 10a. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0072] In some embodiments, the lifting member 21 includes a limit block 214, which is connected to the connecting plate 212. When the lifting drive member 211 drives the rotating power member 22 to descend, the limit block 214 is used to connect to the surface of the machine, thereby limiting the descending position of the connecting plate 212 and the lifting drive member 211.

[0073] In some embodiments, the limit block 214 is provided with an adjustment hole 214a, which is used to adjust the position of the limit block 214 relative to the connecting plate 212 along the lifting direction of the lifting member 21, that is, along the third direction Z, and then adjust the descending position of the connecting plate 212 and the lifting drive member 211. Optionally, the adjustment hole 214a is a long hole.

[0074] In some embodiments, the lifting member 21 includes a buffer portion 215, which is connected to the side of the limit block 214 away from the top wall 11, and the buffer portion 215 is used to connect to the surface of the machine platform to buffer the force of the limit block 214 on the machine platform. Optionally, the buffer portion 215 includes a buffer rubber pad.

[0075] It is understandable that the surface of the machine is provided with a through hole or a groove. When the rotating power member 22 descends, part of the rotating power member 22 moves into the machine through the through hole or is arranged in the groove, so that the limit block 214 is connected to the surface of the machine.

[0076] In some embodiments, the lifting member 21 includes a limit plate (not shown) and a limit switch (not shown), the limit switch is fixed to the first side wall 121, and the limit plate is connected to the connecting plate 212. When the connecting plate 212 moves, the limit plate is driven to move, and when the limit plate moves to the limit switch, the lifting drive member 211 stops driving the connecting plate 212 to move, so as to limit the descending position of the connecting plate 212 and the lifting drive member 211.

[0077] In some embodiments, the rotary power member 22 comprises a motor. In some embodiments, the cleaning member 23 comprises a twist drill.

[0078] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the cleaning device 100 includes a guide member 30, which is used to guide the cleaning member 23. Since the nozzle 200 has a small caliber, a cleaning member 23 with a small diameter is required, and the cleaning member 23 needs to extend out of the fixing seat 10, so that the length of the cleaning member 23 is long, which makes the cleaning member 23 easy to shake, which is not conducive to accurately extending into the nozzle 200. By providing the guide member 30, the guide member 30 is guided in the third direction Z, which is conducive to the cleaning member 23 accurately extending into the nozzle 200, and can reduce the risk of damaging the nozzle 200 due to position deviation.

[0079] In some embodiments, the top wall 11 includes a first wall 11a and a second wall 11b, and the first wall 11a and the second wall 11b are separately arranged. The first wall 11a and the side wall 12 can be separated, and the second wall 11b is fixedly connected to the side wall 12. The opening 111 includes a first opening 111a, and the first opening 111a passes through the first wall 11a.

[0080] In some embodiments, the guide member 30 includes a guide drive member 31 and a guide plate 32, and the guide drive member 31 is connected to the third side wall 123. The guide plate 32 is connected to the guide drive member 31. The guide plate 32 is fixedly connected to the first wall 11a, and the guide plate 32 is provided with a positioning hole 321. The cleaning member 23 passes through the positioning hole 321 and extends into the suction nozzle 200 from the first opening 111a. The guide drive member 31 drives the guide plate 32 to move along the third direction Z, and the guide plate 32 drives the first wall 11a away from the side wall 12. By moving the guide plate 32 and approaching the suction nozzle 200, the end of the cleaning member 23 away from the rotating power member 22 is stabilized, and the shaking of the cleaning member 23 is reduced, which is conducive to the cleaning member 23 accurately extending into the suction nozzle 200, and reducing the risk of damaging the suction nozzle 200 due to position deviation.

[0081] In some embodiments, when the rotating power member 22 is not lifted, the cleaning member 23 does not extend out of the first opening 111a, and a portion of the cleaning member 23 is disposed in the positioning hole 321, which can reduce the step of re-inserting the cleaning member 23 into the positioning hole 321 when moving, thereby reducing the risk of the cleaning member 23 contacting the guide plate 32.

[0082] In some embodiments, along the lifting direction of the guide drive member 31, that is, along the third direction Z, the projection of the first opening 111a is located within the projection of the guide plate 32, and the guide plate 32 and the first opening 111a form a receiving groove 322 for receiving the cleaned attachments in the suction nozzle 200.

[0083] See also Figure 2 , Figure 3 and Figure 5 In some embodiments, the cleaning device 100 includes a top cover mechanism 40, and the top cover mechanism 40 includes a top cover 41 and a connecting rod 42. The connecting rod 42 is connected to the connecting plate 212 and the top cover 41. When the lifting member 21 lifts the rotating power member 22, the connecting plate 212 drives the connecting rod 42 to move, and the connecting rod 42 drives the top cover 41 to move and open the opening 111. When the lifting member 21 causes the rotating power member 22 to descend, the connecting plate 212 drives the connecting rod 42 to move, and the connecting rod 42 drives the top cover 41 to move and close the opening 111, so that when the cleaning device 100 does not clean the suction nozzle 200, the interior of the fixing seat 10 is roughly in a closed state, which can reduce the entry of debris into the accommodating chamber 10a.

[0084] In some embodiments, the opening 111 includes a second opening 111b, the first wall 11a abuts against the second wall 11b to form the second opening 111b, and the second opening 111b penetrates the first wall 11a and the second wall 11b. When the top cover 41 is opened, the top cover 41 is disposed at the second opening 111b, and when the top cover 41 is closed, the top cover 41 is disposed at the opening 111.

[0085] In some embodiments, the connecting rod 42 includes a first connecting rod 421, a second connecting rod 422 and a third connecting rod 423, the second connecting rod 422 is rotatably connected to the first connecting rod 421 and the third connecting rod 423, the first connecting rod 421 is connected to the lifting member 21, and the third connecting rod 423 is rotatably connected to the fixing seat 10. The top cover 41 is connected to the third connecting rod 423. Figure 2 As shown, when the lifting member 21 lifts the rotating power member 22, the connecting plate 212 pushes the first connecting rod 421, the first connecting rod 421 drives the second connecting rod 422 to rotate, the second connecting rod 422 drives the third connecting rod 423 to rotate, and the third connecting rod 423 drives the top cover 41 to flip, so that the top cover 41 opens the opening 111. Figure 5 As shown, when the lifting member 21 causes the rotating power member 22 to descend, the connecting plate 212 pulls the first connecting rod 421, the first connecting rod 421 drives the second connecting rod 422 to rotate, the second connecting rod 422 drives the third connecting rod 423 to rotate, and the third connecting rod 423 drives the top cover 41 to flip, so that the top cover 41 closes the opening 111.

[0086] See also Figure 2 , Figure 4 and Figure 5 When the cleaning device 100 is in use, the moving member first moves the suction nozzle 200 to the top of the cleaning device 100, and then the lifting driving member 211 drives the connecting plate 212 to slide relative to the slide rail 213 along the third direction Z, lifting the rotating power member 22. As the connecting plate 212 moves, the connecting rod 42 opens the top cover 41. When the rotating power member 22 is lifted, the guide driving member 31 drives the guide plate 32 to move along the third direction Z. The guide plate 32 drives the first wall 11a away from the side wall 12 and close to the suction nozzle 200, guiding the cleaning member 23 into the suction nozzle 200, and then the rotating power member 22 drives the cleaning member 23 to rotate. According to the inner wall length of the suction nozzle 200, the moving part drives the suction nozzle 200 to descend in the direction opposite to the third direction Z at a set speed. After descending to the inner wall length of the suction nozzle 200, the lifting drive part 211 drives the connecting plate 212 to slide relative to the slide rail 213 in the direction opposite to the third direction Z, so that the rotating power part 22 descends, and the guide drive part 31 drives the guide plate 32 to move in the direction opposite to the third direction Z. The guide plate 32 drives the first wall body 11a to connect to the side wall 12, and the cleaning part 23 is separated from the suction nozzle 200. With the movement of the connecting plate 212, the connecting rod 42 closes the top cover 41, thereby realizing fully automatic cleaning of the suction nozzle 200.

[0087] In the present application, the lifting member 21 drives the cleaning member 23 to extend into the suction nozzle 200, and the rotating power member 22 drives the cleaning member 23 to rotate, so as to clean the inner wall of the suction nozzle 200, thereby reducing the steps of disassembling and assembling the suction nozzle 200, realizing fully automatic cleaning, and improving the cleaning efficiency. In addition, the lifting member 21, the rotating power member 22 and the cleaning member 23 cooperate to perform cleaning, which can reduce the interference of human factors, make the cleaning force more stable, and reduce the damage to the suction nozzle 200.
