Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a cleaning device for AGV (Automated Guided Vehicle) trolleys. Background Technology

[0002] With the increasing modernization of manufacturing and the rapid development of logistics systems, the application scope of AGVs is constantly expanding. AGVs, also known as material handling robots or AGV carts, are characterized by wheeled movement. Compared with walking, crawling, or other non-wheeled mobile robots, they have advantages such as fast movement, high work efficiency, simple structure, strong controllability, and good safety. Compared with other equipment commonly used in material handling, AGVs do not require the laying of tracks, support frames, or other fixed devices in their activity area and are not limited by site, road, or space.

[0003] In the process of using AGV logistics for product manufacturing, workshops often need AGV vehicles to transport materials or move products. Some products have high environmental requirements, such as electronic products, LCD screens, and precision instruments, thus requiring a high degree of cleanliness from the AGVs. However, in scenarios where AGVs are used extensively, due to wheel wear or other environmental factors, a large amount of debris, dust, and pollutants can accumulate on the AGVs, causing pollution to the production environment. Typically, AGVs are cleaned periodically by workers using cleaning brushes. However, this method has limitations, as the AGVs are heavy and difficult to lift as a whole, resulting in ineffective cleaning of the bottom of the AGVs.

[0004] Therefore, existing technologies present the problem of difficulty in cleaning AGV vehicles. Utility Model Content

[0005] Therefore, it is necessary to provide a cleaning device for AGV vehicles, which aims to solve the problem of difficult cleaning of AGV vehicles in the prior art.

[0006] In a first aspect, embodiments of this application provide a cleaning device for an AGV (Automated Guided Vehicle), comprising:

[0007] frame;

[0021] A water storage tank is slidably mounted on the first rod. The direction in which the water storage tank is slidable is a second direction, which is parallel to the extension direction of the first rod. The opening direction of the water storage tank is away from the first rod. The length of the water storage tank is less than the length of the first rod. The water storage tank includes two tank walls that are arranged opposite to each other in a direction parallel to the extension direction of the first rod.

[0022] At least one brush is provided at both ends on the walls of the two water tanks;

[0023] At least one first rotary motor is mounted on at least one end of the first rod and located at at least one end of the water storage tank. The first rotary motor can drive the water storage tank and the at least one brush to slide on the first rod.

[0024] In some embodiments, at least one of the brushes is a circular rotating brush, with both ends of the circular rotating brush rotatably fixed to the two walls of the water tank.

[0025] The cleaning mechanism also includes a second rotary motor, which is mounted on the wall of the water tank and can drive the circular rotating brush to rotate.

[0026] In some embodiments, in the first direction, the at least one brush of the cleaning mechanism comprises:

[0029] The drying brush is a circular rotating brush, and is spaced apart from the bottom wall of the water storage tank. The distance between the drying brush and the bottom wall of the water storage tank is a second distance, and the first distance is less than the second distance.

[0030] In some embodiments, when the water tank is filled with a preset amount of water, at least part of the cleaning brush is submerged in the water, and the drying brush is spaced apart from the water surface.

[0031] In some embodiments, the cleaning mechanism further includes:

[0032] A level gauge is installed inside the water storage tank, and the level gauge is used to detect the water level in the water storage tank.

[0033] A water inlet solenoid valve is connected to the water inlet of the water storage tank. The water inlet solenoid valve is used to control the opening and closing of the water inlet.

[0034] A water outlet solenoid valve is connected to the water outlet of the water storage tank. The water outlet solenoid valve is used to control the opening and closing of the water outlet.

After the first lifting mechanism controls the forks to rise, the cleaning mechanism can slide on the two first extension arms to below the forks. Firstly, by using a single cleaning device, the AGV can be lifted and cleaned, reducing the number of personnel required for cleaning and lowering labor costs. Secondly, the forks can be raised and lowered to expose the AGV wheels. The cleaning mechanism can then slide on the two first extension arms to below the forks, allowing it to contact and clean the AGV wheels. This not only achieves lifting and cleaning of the AGV wheels using a single cleaning device, but also reduces the footprint of the cleaning device, improving cleaning convenience within the limited space of a factory and ensuring that all parts of the AGV are thoroughly cleaned.

[0068] As described in the background section, it is necessary to provide a cleaning device for AGV carts to solve the problems of difficult cleaning of AGV carts in the prior art. For example, it is difficult to clean the wheels when cleaning AGV carts manually. For example, multiple devices or apparatuses are required to clean AGV carts, resulting in multiple devices or apparatuses occupying a large area. In the limited space in the factory, this causes problems such as inconvenience in cleaning or inability to completely clean all parts.

[0069] It is necessary to provide a cleaning device for AGV carts, which aims to solve the problem of difficult cleaning of AGV carts in the prior art.

[0070] Based on the aforementioned technical problems, the inventors have discovered that a cleaning device for an AGV (Automated Guided Vehicle) includes: a frame; a lifting plate, which is movably mounted on one side of a first surface of the frame; two forks, each including a first end movably connected to the lifting plate, and a first fork portion extending away from the first end and along a first direction, the first direction being perpendicular to the first surface; a first lifting mechanism, disposed on the frame, which can drive the lifting plate to rise and fall in the vertical direction, thereby driving the forks to rise and fall in the vertical direction; a first width adjustment mechanism, disposed on the lifting plate, which can adjust the horizontal distance between the two forks; two first extension arms, each including a second end connected to the lifting plate, and a first extension portion extending away from the second end and along the first direction, with the two forks disposed between the two first extension arms in the horizontal direction; and a cleaning mechanism, with its opposite ends slidably disposed on the two first extension portions; wherein, after the first lifting mechanism controls the forks to rise, the cleaning mechanism can slide on the two first extension portions to below the forks. The forks, first extension arm, and cleaning mechanism are all housed in the same cleaning device. After the first lifting mechanism raises the forks, the cleaning mechanism can slide along the two first extension arms to below the forks. Firstly, by using a single cleaning device to lift and clean the AGV, the number of personnel required for cleaning is reduced, thus lowering labor costs. Secondly, the forks can be raised and lowered to expose the AGV's wheels, allowing the cleaning mechanism to slide along the two first extension arms to below the forks and clean the wheels. This not only achieves lifting and wheel cleaning within a single device, but also minimizes the footprint of the cleaning device, improving cleaning convenience within the limited space of a factory and ensuring thorough cleaning of all parts of the AGV.

[0071] The above is the core idea of ​​this application.

[0078] This application provides a cleaning device 100 for an AGV (Automated Guided Vehicle) cart. The cleaning device 100 includes a frame 10, a lifting plate 20, two forks 30, a first lifting mechanism 90, a first width adjustment mechanism 40, two first extension arms 50, and a cleaning mechanism 60. The lifting plate 20 is movably mounted on one side of the first surface 100a of the frame 10. Each of the two forks 30 includes a first end 31 movably connected to the lifting plate 20, and a first fork portion 32 extending away from the first end 31 and along a first direction X, perpendicular to the first surface 100a. The first lifting mechanism 90 is disposed on the frame 10 and can drive the lifting plate 20 to move up and down in the vertical direction, thereby driving the forks 30 to move up and down in the vertical direction. The first width adjustment mechanism 40 is disposed on the lifting plate 20. The wide mechanism 40 can adjust the horizontal distance between the two forks 30; each of the two first extension arms 50 includes a second end 51 connected to the frame 10, and a first extension portion 52 extending away from the second end 51 and along the first direction X. In the horizontal direction, the two forks 30 are disposed between the two first extension arms 50; the opposite ends of the cleaning mechanism 60 are slidably disposed on the two first extension portions 52 respectively; wherein, after the first lifting mechanism 90 controls the forks 30 to rise, the cleaning mechanism 60 can slide on the two first extension portions 52 to below the forks 30.

[0079] For example, in some embodiments, the first end 31 of the fork 30 is movably connected to the lifting plate 20, and the lifting plate 20 and the first width adjustment mechanism 40 have different structures. For example, the first width adjustment mechanism 40 is mounted on the lifting plate 20, and the first end 31 of the fork 30 is movably connected to the first width adjustment mechanism 40, so that the first width adjustment mechanism 40 can adjust the horizontal distance between the two forks 30.

[0080] For example, in some other embodiments, the first end 31 of the fork 30 is movably connected to the lifting plate 20, which has the same structure as the first width adjustment mechanism 40. For example, the first width adjustment mechanism 40 acts as the lifting plate 20. The first width adjustment mechanism 40 is mounted on one side of the first surface 100a of the frame 10 and is movably connected to the first width adjustment mechanism 40 / lifting plate 20, so that the first width adjustment mechanism 40 can adjust the horizontal distance between the two forks 30.

[0081] For example, the first lifting mechanism 90 is disposed on the frame 10. The first lifting mechanism 90 can drive the lifting plate 20 to rise and fall in the vertical direction, thereby driving the fork 30 to rise and fall in the vertical direction. The first lifting mechanism 90 can be any lifting mechanism in the prior art, as long as it can drive the lifting plate 20 to rise and fall in the vertical direction. For example, the first lifting mechanism 90 includes a lifting motor and a steel cable. One end of the steel cable is connected to the lifting plate 20, and the other end of the steel cable is connected to the output shaft of the lifting motor in a synchronous rotational manner. When the lifting motor rotates, it drives the steel cable to move or wind, so that the lifting plate 20 can be driven to rise and fall in the vertical direction.

[0082] For example, the up and down direction is the vertical direction.

[0083] For example, the first width adjustment mechanism 40 can adjust the horizontal distance between the two forks 30. The first width adjustment mechanism 40 can be any width adjustment mechanism in the prior art, as long as it can adjust the horizontal distance between the two forks 30. For example, the first width adjustment mechanism 40 includes a track and a motor. The first end 31 of the forks is connected to the track. The motor can drive the track to move or wind, thereby driving the forks 30 to move horizontally, so that the first width adjustment mechanism 40 can adjust the horizontal distance between the two forks 30. As another example, the first width adjustment mechanism 40 includes a steel cable and a motor. The first ends 31 of the two forks are sequentially wound and connected by the steel cable. The other end of the steel cable is connected to the output shaft of the motor in a synchronously rotatable manner. The motor can drive the steel cable to move or wind, thereby driving the forks 30 to move horizontally, for example, driving the two forks 30 to move closer to each other, so that the first width adjustment mechanism 40 can adjust the horizontal distance between the two forks 30.

[0084] For example, two forks 30 are disposed between two first extension arms 50, that is, in the horizontal direction, the two first extension arms 50 are disposed outside the two forks 30.

[0085] For example, both the first fork portion 32 and the first extension portion 52 extend along a first direction X. Each fork 30 includes a first end 31 and a first fork portion 32. Each first extension arm 50 includes a second end 51 and a first extension portion 52.

[0086] For example, the two opposite ends of the cleaning mechanism 60 are slidably disposed on the two first extensions 52. After the first lifting mechanism 90 controls the fork 30 to rise, the cleaning mechanism 60 can slide on the two first extensions 52 to the bottom of the fork 30. Before the first lifting mechanism 90 raises the fork 30, the cleaning mechanism 60 rests on the two first extensions 52 between a portion of the fork 30 and the second end 51. Only after the first lifting mechanism 90 controls the fork 30 to rise will the fork 30 not obstruct the movement of the cleaning mechanism 60, thus allowing the cleaning mechanism 60 to slide on the two first extensions 52 to the bottom of the fork 30 after the first lifting mechanism 90 controls the fork 30 to rise.

[0087] In this embodiment, a cleaning device 100 for an AGV (Automated Guided Vehicle) includes: a frame 10; a lifting plate 20, which is movably mounted on one side of a first surface 100a of the frame 10; two forks 30, each including a first end 31 movably connected to the lifting plate, and a first fork portion 32 extending away from the first end 31 and along a first direction X, the first direction X being perpendicular to the first surface 100a; a first lifting mechanism 90, disposed on the frame 10, which can drive the lifting plate 20 to move up and down in the vertical direction, thereby driving the forks 30 to move up and down in the vertical direction; and a first width adjustment mechanism 40. The first width adjustment mechanism 40, placed on the lifting plate 20, can adjust the horizontal distance between the two forks 30. Each of the two first extension arms 50 includes a second end 51 connected to the lifting plate 20 and a first extension portion 52 extending away from the second end 51 and along the first direction X. Horizontally, the two forks 30 are positioned between the two first extension arms 50. A cleaning mechanism 60 is provided, with its opposite ends slidably mounted on the two first extension portions 52. After the first lifting mechanism 90 controls the forks 30 to rise, the cleaning mechanism 60 can slide on the two first extension portions 52 to below the forks 30. That is, the forks 30, first extension arms 50, and cleaning mechanism 60 are all housed in the same cleaning device 100. After the first lifting mechanism 90 controls the forks 30 to rise, the cleaning mechanism 60 can slide on the two first extension portions 52 to below the forks 30. Firstly, by using a single cleaning device, the AGV trolley 200 can be lifted and cleaned, reducing the number of personnel required for cleaning and lowering labor costs. Secondly, the forks 30 can be raised and lowered to lift the AGV trolley 200, exposing the wheels 201 of the AGV trolley 200. The cleaning mechanism 60 can slide on the two first extensions 52 to the underside of the forks 30, so that the cleaning mechanism 60 can contact and clean the wheels 201 of the AGV trolley 200. This not only achieves the lifting of the AGV trolley 200 to expose the wheels 201 and cleaning of the wheels 201 by the same cleaning device, but also the cleaning device occupies a small area. In the limited space in the factory, it can improve the convenience of cleaning and ensure that all parts of the AGV trolley 200 can be completely cleaned.

[0088] In some embodiments, the fork 30 further includes a first sub-fork connecting portion 33 connecting the first fork portion 32, and a second sub-fork connecting portion 34 connecting the first sub-fork connecting portion 33 and the first end 31. In the vertical direction, the second sub-fork connecting portion 34 is located above the first fork portion 32, and at least a portion of the first sub-fork connecting portion 33 extends in the vertical direction. The two first extension arms 50 are connected to the frame 10 on the side of the first fork portion 32 near the first surface 100a. In the horizontal direction, a first space portion 101 is provided between the second end 51 and the first fork portion 32. When the cleaning mechanism 60 is located on the two first extension arms 50 near the second end 51, the cleaning mechanism 60 is located below the second sub-fork connecting portion 34 and in the first space portion 101.

[0089] For example, in the vertical direction, the second sub-fork connection 34 is located above the first fork portion 32, and at least part of the first sub-fork connection 33 extends in the vertical direction. The second sub-fork connection 34, the first sub-fork connection 33 and the first fork portion 32 can form a "Z" shape or other structure, so that the two first extension arms 50 are connected to the frame 10 on the side of the first fork portion 32 near the first surface 100a. In the horizontal plane, the second end 51 has a first space portion 101 between it and the first fork portion 32.

[0090] For example, when the cleaning mechanism 60 is located on the two first extended arms 50 near the second end 51, the cleaning mechanism 60 is located below the second fork connection 34 and in the first space 101, that is, the first space 101 can hold the cleaning mechanism 60, thus reducing the volume of the cleaning device 100 of the AGV trolley.

[0091] In some embodiments, when the cleaning mechanism 60 is located near the second end 51 on the two first extendable arms 50, the lifting plate 20 is positioned above the cleaning mechanism 60.

[0092] For example, when the cleaning mechanism 60 is near the second end 51 on the two first extended arms 50, the lifting plate 20 is located above the cleaning mechanism 60, so that the lifting plate 20 and the cleaning mechanism 60 will not interfere or conflict, and the lifting plate 20 and the cleaning mechanism 60 will not collide when the lifting plate 20 rises and falls.

[0093] In some implementations, such as Figure 9 and Figure 10As shown, the cleaning mechanism 60 includes a first rod 61, a water storage tank 62, at least one brush 63, and at least one first rotary motor 64. The two ends of the first rod 61 are slidably mounted on two first extended arms 50, and the sliding direction of the first rod 61 is a first direction X. The water storage tank 62 is slidably mounted on the first rod 61, and the sliding direction of the water storage tank 62 is a second direction Y, which is parallel to the extension direction of the first rod 61. The opening direction of the water storage tank 62 is opposite to that of the first rod 61, and the length of the water storage tank 62 is less than the length of the first rod 61. The water storage tank 62 includes two tank walls arranged opposite each other in a direction parallel to the extension direction of the first rod 61. At least one brush 63 has its two ends respectively mounted on the two tank walls. The first rotary motor 64 is mounted on at least one end of the first rod 61 and is located at least at one end of the water storage tank 62. The first rotary motor 64 can drive the water storage tank 62 and at least one brush 63 to slide on the first rod 61.

[0094] For example, the first rod 61 may be plate-shaped or circular rod-shaped, without limitation.

[0095] For example, the first lever 61 can slide in the first direction X, so that after the first lifting mechanism 90 controls the forks 30 to rise, the cleaning mechanism 60 can slide on the two first extensions 52 to below the forks 30.

[0096] For example, the first rod 61 can slide in the first direction X, and the water tank 62 can slide in the second direction Y, so that the cleaning mechanism 60 can clean the wheel 201 at various parts on the horizontal plane.

[0097] For example, a first rotary motor 64 is mounted on at least one end of a first rod 61 and is located at least at one end of a water storage tank 62. The first rotary motor 64 can drive the water storage tank 62 and at least one brush 63 to slide on the first rod 61. The principle by which the first rotary motor 64 enables the cleaning mechanism 60 to move is not described in detail here, and can be any existing technology, such as the first lifting mechanism 90 or the first width adjustment mechanism 40, which can move the cleaning mechanism 60 via tracks or steel cables.

[0098] In some implementations, such as Figure 9 and Figure 10 As shown, at least one brush 63 is a circular rotating brush, and the two ends of the circular rotating brush are rotatably fixed on the two water tank walls respectively; the cleaning mechanism 60 also includes a second rotating motor 65, which is disposed on the water tank wall and can drive the circular rotating brush to rotate.

[0099] For example, a second rotary motor 65 is mounted on the wall of the water tank. The second rotary motor 65 can drive a circular rotary brush to rotate, thereby cleaning the wheel 201.

[0100] In some implementations, such as Figure 9 and Figure 10 As shown, in the first direction X, at least one brush 63 of the cleaning mechanism 60 includes a front brush 631, a cleaning brush 632, and a drying brush 633 arranged sequentially. The front brush 631 is fixedly disposed on the outside of the water storage tank 62; the cleaning brush 632 is a circular rotating brush and is spaced apart from the bottom wall of the water storage tank 62, and the distance from the cleaning brush 632 to the bottom wall of the water storage tank 62 is a first distance; the drying brush 633 is a circular rotating brush and is spaced apart from the bottom wall of the water storage tank 62, and the distance from the drying brush 633 to the bottom wall of the water storage tank 62 is a second distance, and the first distance is less than the second distance.

[0101] For example, the front brush 631 first pre-cleans the wheel 201 to brush away large dirt on the wheel 201, and then the brush 632 washes the wheel 201 with clean water or detergent in the water tank 62. After cleaning, the brush 633 dries the wheel 201 to remove water stains.

[0102] In some implementations, such as Figure 9 and Figure 10 As shown, when the water tank 62 is filled with a preset amount of water, the cleaning brush 632 is at least partially submerged in the water surface, and the brush 633 is set at an interval from the water surface to be dried.

[0103] For example, the first distance is less than the second distance, so that when the water tank 62 is filled with a preset amount of water, the cleaning brush 632 is at least partially submerged in the water surface, and the drying brush 633 is spaced apart from the water surface, so as to realize the respective functions of the cleaning brush 632 and the drying brush 633.

[0104] In some implementations, such as Figure 11 and Figure 12 As shown, the cleaning mechanism 60 also includes a level gauge 66, an inlet solenoid valve 67, an outlet solenoid valve 68, and a drain pump 69. The level gauge 66 is installed inside the water storage tank 62 and is used to detect the water level in the tank. The inlet solenoid valve 67 is connected to the inlet 601 of the water storage tank 62 and is used to control the opening and closing of the inlet 601. The outlet solenoid valve 68 is connected to the outlet 602 of the water storage tank 62 and is used to control the opening and closing of the outlet 602. The drain pump 69 is connected to the outlet solenoid valve 68 and is used to enhance the drainage speed; the drain pump 69 can open synchronously with the outlet solenoid valve 68.

[0105] In some implementations, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 , Figure 13As shown, the frame 10 includes at least one lower crossbeam 13, at least two uprights 12, and at least one upper crossbeam 11. The upper ends of the uprights 12 are connected to the upper crossbeam 11, and the lower crossbeam 13 connects to different uprights 12 near the lower ends of the uprights 12. The first lifting mechanism 90 includes a rotating wheel 91, a lifting motor 92, and a steel cable 93. The rotating wheel 91 is disposed on the upper crossbeam 11, and the rotation axis of the rotating wheel 91 is parallel to the first surface 100a; the lifting motor 92 is mounted on the lower crossbeam 13; the steel cable 93 passes around the rotating wheel 91, and one end is connected to the lifting plate 20, and the other end is connected to the output shaft of the lifting motor 92, which can rotate synchronously.

[0106] For example, the first lifting mechanism 90 may also include other components such as gears or a first rotating shaft. The steel cable 93 may be wound around the gears or the first rotating shaft. When the output shaft of the lifting motor 92 rotates, it drives the gears or the first rotating shaft to rotate synchronously, and then drives the steel cable 93 to rotate or wind synchronously, thereby causing the lifting plate 20 to rise or fall in the vertical direction.

[0107] In some implementations, such as Figure 1 and Figure 2 , Figure 13 As shown, the cleaning device 100 of the AGV trolley also includes a counterweight mechanism 70, which is connected to the steel cable 93 and is connected between the rotating wheel 91 and the lifting motor 92. The counterweight mechanism 70 includes a counterweight 71 and a guide wheel 72. The guide wheel 72 is mounted on the counterweight 71. The steel cable 93 extends downward around the rotating wheel 91 and is connected to the output shaft of the lifting motor 92 after being wound around the guide wheel 72. The steel cable 93 can rotate synchronously.

[0108] For example, by setting the guide wheel 72 to synchronize the movement of the steel cable 93, the horizontal stability of the counterweight 71 during the rising or falling process can be improved, especially when there are two or more steel cables 93, the improvement effect is more significant.

[0109] It should be noted that, in some embodiments, the first lifting mechanism 90 includes a double-row chain lifting sub-mechanism driven by a geared servo motor and linear guide rails to achieve reciprocating up-and-down movement. When the first end 31 of the fork 30 is movably connected to the first width adjustment mechanism 40, the fork 30 can be fixed on two linear guide rails and left and right helical screw devices. The rotation of the motor drives the left and right synchronous belts to rotate, so that the two forks can move in opposite directions to adjust the distance between the two forks. The counterweight mechanism 70 helps the first lifting mechanism 90 to lift the fork 30 and the AGV trolley 200, reducing the load on the geared servo motor, and guides the counterweight mechanism 70 to move smoothly up and down through the guide wheel 72.

[0110] It should be noted that in some embodiments, the replenishment and drainage of the water storage tank 62 are achieved through automatic control. The water storage tank 62 is equipped with a level gauge 66. During replenishment, the inlet solenoid valve 67 opens, allowing water to enter the tank. When the level gauge 66 senses that the water has reached a predetermined level, the inlet solenoid valve 67 closes, stopping the replenishment. During drainage, the PLC controls the outlet solenoid valve 68 to open, then controls the drainage pump 69 to start operating. Wastewater will then exit through the drain connector, first passing through a filter, and then flowing through the drainage pump 69 and the outlet solenoid valve 68 to the designated drainage location in the plant maintenance section. The filter screen of the wastewater filter is replaceable. The automatic drainage function is programmed to achieve fully automatic replenishment and drainage.

[0111] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0112] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
