Description

Technical Field

[0001] This invention relates to the field of wheel cleaning technology, and in particular to a wheel cleaning device. Background Technology

[0002] AGVs are devices used to transport materials between different workshops or different processes within the same workshop. After prolonged operation, AGV wheels accumulate dust, debris, and other contaminants, which can damage and contaminate the ground during operation. This does not meet the cleanliness requirements of cleanrooms or workshops with specific cleanliness requirements. Therefore, regular cleaning of AGV wheels is necessary.

[0003] Existing wheel cleaning methods are mainly divided into two types: manual cleaning and machine cleaning. Manual cleaning mainly involves lifting the AGV as a whole with a forklift or other equipment and then manually cleaning the wheels; or removing the wheels for washing. This method is relatively inconvenient and inefficient.

[0004] Machine cleaning can typically be achieved in two ways. One method involves using a cleaning device with its own lifting mechanism. By finding suitable leverage points on the AGV body, the entire AGV is lifted. The other method utilizes the AGV's own lifting mechanism. A clamping mechanism is installed on the cleaning device. When the lifting platform on the AGV reaches its highest point, the clamping mechanism clamps the platform. Then, the lifting mechanism is shortened, using its reaction force to lift the entire AGV. After the AGV is lifted, the cleaning mechanism is moved to the bottom of the AGV to clean or wash its wheels.

[0005] Existing machine cleaning methods suffer from the following main problems. First, they require high rigidity from the AGV chassis. Whether using the lifting mechanism of the cleaning equipment or the AGV's own lifting mechanism, the AGV chassis must possess high rigidity. Simultaneously, this lifting cleaning method presents safety issues. With the AGV's significant weight, cleaning the wheels from underneath after lifting it poses a substantial safety risk. Furthermore, insufficient chassis rigidity can lead to difficulty finding suitable leverage points during lifting, causing chassis deformation. Second, existing AGVs often require carrying functions, typically incorporating carriers. During cleaning, the reduced number of support points and increased center of gravity make the AGV prone to tipping over. The AGV's substantial weight further complicates matters, making wheel cleaning from underneath after lifting it a significant safety risk. Finally, existing machine cleaning methods demand high precision in AGV positioning. In addition, existing machine cleaning equipment has a complex structure, a cumbersome cleaning process, and low work efficiency. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wheel cleaning device. The device has a simple structure, does not require lifting the vehicle during cleaning, has high cleaning efficiency, high safety performance, can avoid collision between the vehicle body and the cleaning device, does not require high positioning accuracy, has excellent cleaning effect, and has self-cleaning ability.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Reference Figures 1 to 8 As shown, the present invention discloses a wheel cleaning device, including a body, a cleaning unit and a drying unit.

[0034] The main body 1 includes a cleaning channel arranged horizontally. Specifically, the cleaning channel is formed by extending through the main body 1 along its length. Thus, the two ends of the cleaning channel along its length are defined as the inlet and the outlet, respectively. The cleaning channel includes a cleaning section 11 near the inlet and a drying section 12 near the outlet. The cleaning section 11 and the drying section 12 together form the entire cleaning channel. When the wheel cleaning equipment is working, the vehicle to be cleaned enters the cleaning channel from the inlet, the wheels are cleaned by the cleaning unit, the vehicle is dried by the drying unit, and finally it leaves the cleaning channel from the outlet. To facilitate the entry and exit of the vehicle to be cleaned from the cleaning channel, an uphill ramp 13 is provided at the inlet of the cleaning channel, and a downhill ramp 14 is provided at the outlet of the cleaning channel.

[0035] The cleaning unit is located within the cleaning section 11. Specifically, the cleaning unit includes a frame and cleaning components mounted on the frame. The frame includes an upper frame 21 and a lower frame 22 arranged vertically, with a connecting frame assembly between them. The lower frame 22 is constructed using aluminum profiles and angle brackets to form a rectangular frame structure. The upper frame 21 can be made of a rectangular plate of a size adapted to the lower frame 22, with several reinforcing ribs on its bottom surface to enhance its load-bearing capacity. The connecting frame assembly includes at least two first connecting frames 23 and at least two second connecting frames 24. The two first connecting frames 23 are symmetrically installed on the outer side of one end of the upper frame 21 and the lower frame 22. The two second connecting frames 24 are symmetrically installed on the outer side of the other end of the upper frame 21 and the lower frame 22.

[0036] The cleaning assembly includes a cleaning belt 31 and a drive unit mounted on a frame. The drive unit drives the cleaning belt 31 to move along the length of the frame. The drive unit includes a drive roller 32 and a driven roller 33 mounted on a connecting frame assembly. The two ends of the drive roller 32 are respectively mounted on two first connecting frames 23, such that the length of the drive roller 32 is perpendicular to the length of the frame. The two ends of the driven roller 33 are respectively mounted on two second connecting frames 24, thereby making the drive roller 32 parallel to the driven roller 33.

[0037] The driving component also includes an adjusting roller 34 disposed within the frame, with both ends of the adjusting roller 34 adjustablely mounted on the two first connecting brackets 23. The outer diameter of the adjusting roller 34 is smaller than the diameter of the driving roller 32. Simultaneously, the height of the axis of the adjusting roller 34 is higher than the lowest point of the roller surface of the driving roller 32. Furthermore, the projection of the axis of the adjusting roller 34 in the height direction is lower than the projection of the axis of the driving roller 32 in the height direction. Specifically, the cleaning belt 31 includes an inner belt layer 35 and an outer cleaning layer 36. The cleaning belt 31 is sequentially wound around the driving roller 32, the driven roller 33, and the adjusting roller 34 to form an end-to-end connected structure, with the belt layer 35 of the cleaning belt 31 contacting the roller surfaces of the driving roller 32 and the driven roller 33, and simultaneously, the cleaning layer 36 of the cleaning belt 31 contacting the roller surface of the adjusting roller 34.

[0038] At this point, the cleaning belt 31 is divided into an upper section and a lower section. The upper frame 21 is located between the upper and lower sections of the cleaning belt 31 and preferably contacts the belt layer of the upper section, thereby supporting the upper section. The adjusting roller 34 is configured to tension the cleaning belt 31 on one hand and to squeeze the cleaning layer 36 of the cleaning belt 31 on the other hand, thereby removing the accumulated sewage in the cleaning layer 36 through squeezing. In this embodiment, the positions of the drive roller 32 and the driven roller 33 can be adaptively adjusted. The motor built into the drive roller 32 can drive itself to rotate, thereby driving the cleaning belt 31 to move.

[0039] Furthermore, the first connecting frame 23 includes an outer frame and a support portion 41 disposed within the outer frame. The top edge of the outer frame is provided with a "V-shaped" relief groove 42. The support portion 41 is provided with a guide groove 43 extending towards the bottom of the relief groove 42. A through hole is formed from the relief groove 42 to the guide groove 43, penetrating the support portion 41. An elastic element 44 is provided within the guide groove 43. The end of the adjusting roller 34 is provided with a threaded hole in the radial direction. The extension direction of the threaded hole is the same as the extension direction of the guide groove 43, so that the end of the adjusting roller 34 can slide along the extension direction of the guide groove 43. The elastic deformation direction of the elastic element 44 is perpendicular to the axial direction of the adjusting roller 34. In this way, the elastic element 34 can limit the sliding of the end of the adjusting roller 34 within the guide groove 43. An adjusting bolt 45 is inserted into the threaded hole through the relief groove 42, so that the adjusting bolt 45 passes through the elastic element 44 from the relief groove 42 and connects to the end of the adjusting roller 34. The position of the adjusting roller 34 can be adjusted along the length of the guide groove 43 by rotating the adjusting bolt 45, thereby achieving the adjustment of the position of the adjusting roller 34. The elastic element 44 includes, but is not limited to, a spring, which is sleeved on the adjusting bolt.

[0040] Furthermore, the support portion 41 includes a vertical side 46 and an inclined side 47, such that the top width of the support portion 41 connecting to the outer frame is greater than the bottom width of the support portion 41 connecting to the outer frame. The guide groove 43 is inclined from the vertical side 46 of the support portion 41 towards the recess groove 42. Moreover, the connection position between the drive roller 32 and the first connecting frame 23 is located on one side of the inclined side 47 of the support portion 41. This arrangement allows the first connecting frame 23 to construct the installation and adjustment space for the adjusting roller 34 while ensuring support strength, without requiring additional installation components, thereby achieving structural simplification and cost reduction.

[0041] In detail, the present invention also includes a spray assembly. This spray assembly includes at least one spray nozzle 51 located below the cleaning belt 31, as well as a water pipe and a water tank, with the spray nozzle 51 connected to the water tank via the water pipe. During the cleaning process, the spray nozzle 51 can spray clean water onto the cleaning belt 31, wetting it and thus improving the cleaning effect on the wheel. Alternatively, an appropriate amount of detergent can be added to the water tank to specifically wash away oil stains and other special impurities adhering to the wheel surface.

[0042] Specifically, the present invention also includes at least one scraper 52 disposed on the frame. The scraper 52 is disposed below the cleaning belt 31 and is fixed to the profile frame by a scraper bracket 53 with a slotted hole. The distance between the scraper 52 and the cleaning belt 31 can be adjusted by adjusting the height of the scraper bracket 53. During the cleaning process of the cleaning belt 31, the dirt on the surface of the flat belt, which has been wetted by the cleaning fluid, will also be scraped off by the scraper 52, thereby preventing the dirt accumulated on the cleaning belt 31 from contaminating the wheel. At the same time, it ensures the cleanliness of the cleaning belt 31 and can extend the service life of the cleaning belt 31.

[0043] In one possible embodiment, two cleaning components are provided, arranged side-by-side at the bottom of the cleaning channel of the main body 1, for cleaning the wheels on both sides of the AGV vehicle respectively. Of course, in this embodiment, the wheels to be cleaned can be AGV vehicles, or other handling or transport vehicles, such as AMR vehicles.

[0044] In this embodiment, the cleaning layer 36 of the cleaning belt 31 is made of plush fabric, and the plush fabric is fixed to the belt layer 35 of the cleaning belt 31.

[0045] In one possible embodiment, the plush fabric layer includes several plush fabric pieces, and the belt layer 35 is provided with Velcro. The plush fabric pieces are detachably attached to the Velcro of the belt layer 35. When it is necessary to replace a damaged plush fabric piece, simply tear off the damaged plush fabric piece and replace it with a new one.

[0046] In another possible embodiment, the cleaning layer 36 includes several cleaning structures fixed to the belt layer 35. This cleaning structure comprises three layers: a bottom waterproof layer 61 with a U-shaped cross-section; a top waterproof layer 62 fixed to the waterproof layer 61; and a receiving cavity 63 formed between the waterproof layer 61 and the water-permeable cleaning layer 62, within which an absorbent layer 64 is provided. Specifically, the waterproof layer 61 can be made of soft plastic or waterproof cloth and adhered to the belt layer 35. The water-permeable cleaning layer 62 can be made of mesh fabric. The absorbent layer 64 can be made of sponge. After being sprayed with water, the mesh fabric becomes wet, cleaning the wheel. The sponge absorbs a large amount of cleaning liquid, which is squeezed out when the wheel presses against the cleaning layer 36, thus increasing the cleaning effect. Larger dirt adhering to the cleaned mesh can be scraped off by the scraper 51. Simultaneously, the wastewater after cleaning permeates into the receiving cavity 63 and is absorbed by the sponge, effectively preventing the wastewater from re-contaminating the cleaned wheel.

[0047] It should be noted that the waterproof layer 61 has an opening on the side, which facilitates quick replacement of the sponge.

[0048] In addition, the present invention also includes a blocking assembly disposed between the cleaning section 11 and the drying section 12. The blocking assembly includes a liftable baffle 71 for blocking the vehicle to be cleaned, and a lifting assembly for driving the baffle 71 to rise and fall. When the vehicle to be cleaned travels onto the cleaning belt 31, the baffle 71 rises and blocks the front of the vehicle, and the vehicle rests against the baffle 71, thereby ensuring that the vehicle runs stably on the cleaning belt 31 and preventing incomplete cleaning of the wheels due to the vehicle leaving the cleaning belt 31 at too high a speed.

[0049] Specifically, the lifting assembly includes a drive motor 72, a slide rail 73 arranged along the height direction of the body 1, a synchronous pulley assembly, and a mounting bracket 74. The synchronous pulley assembly includes a synchronous belt 75, and a first synchronous pulley 76 and a second synchronous pulley 77 arranged along the height direction, with the first synchronous pulley 76 located below the second synchronous pulley 77. The synchronous belt 75 sequentially winds around the first synchronous pulley 76 and the second synchronous pulley 77. The output end of the drive motor 72 is equipped with a sprocket assembly. The drive motor 72 is connected to the first synchronous pulley 76 via the sprocket assembly 79, and the mounting bracket 74 is connected to the synchronous belt 75. Simultaneously, a baffle 71 is connected to the mounting bracket 74, and the baffle 71 is slidably connected to the slide rail 73 via a slider 78. The slider 78 moves vertically in conjunction with the slide rail 73. Thus, when the drive motor 72 is running, the sprocket assembly 79 drives the first synchronous pulley 76 and the second synchronous pulley 77 to rotate, thereby driving the synchronous belt 75 to move, thus enabling the baffle 71 to move up and down.

[0050] The drying unit includes at least one warm air device located outside the main body. Specifically, in this embodiment, two warm air devices 15 are provided, which can be hot air blowers. The two warm air devices 15 are respectively located on the outer side of the drying section. Several ventilation holes 16 communicating with the warm air devices are provided on both sides of the drying section. When the warm air devices are working, warm air can be introduced into the drying section of the cleaning channel through the ventilation holes. The cleaning channel has a supporting base plate in the drying section, the height of which is the same as the height of the cleaning components. After the AGV vehicle's wheels are cleaned, it enters the drying section. The hot air generated by the hot air blower enters the cleaning channel through the ventilation holes 16 to dry the cleaned AGV vehicle's wheels. After drying, the vehicle leaves the cleaning equipment via the downhill ramp 14 at the exit.

[0051] Furthermore, the wheel cleaning equipment of the present invention also includes a safety protection device, which includes a safety laser radar located at the entrance and anti-collision contact strips located on the inner walls of both sides of the cleaning channel. The safety laser radar is paired at the entrance and will sound an alarm when a vehicle travels beyond the safe operating area. The anti-collision contact strips can protect the cleaning equipment and the vehicle itself during the wheel cleaning process, preventing the vehicle from colliding with the cleaning equipment while driving. Additionally, the drying unit is equipped with warning lights to indicate the operating status of the device. Emergency stop buttons are also installed on the outer casing of the wheel cleaning equipment to stop the operation of the device in case of an emergency.

[0052] The working principle and process of this invention are as follows:

[0053] The AGV (Automated Guided Vehicle) ascends the ramp via an incline and enters the cleaning unit within the cleaning channel through the main entrance of the device. A safety lidar at the entrance detects the AGV. Once the AGV is on the cleaning belt, a baffle rises, and the AGV's front end rests against the baffle. A motor inside the drive roller rotates, causing the drive roller to rotate, thus initiating the movement of the cleaning belt. The cleaning belt moves in the same direction as the AGV's wheels, allowing the AGV wheels to move forward continuously on the flat belt while the AGV itself remains stationary. Simultaneously, spray nozzles spray cleaning fluid, wetting the cleaning belt. As the AGV wheels move forward, the cleaning layer of the belt repeatedly wipes away dirt from the wheels, wrapping around the contact areas and wiping away dirt in the process. In practice, the cleaning fluid is changed according to the type of dirt encountered in different applications to improve wheel cleaning effectiveness. After cleaning, the baffle lowers to stop obstructing the AGV, the drive roller stops rotating, and the AGV enters the drying section, where a hot air blower dries the water stains from the wheels. After drying, the AGV vehicle drives away from the drying unit via a downhill ramp. The entire cleaning process is complete. During this process, there is no water splashing as is seen in existing technologies, and it is gentle on the vehicle's internal electrical components and on its storage or handling equipment.

[0054] In summary, the wheel cleaning device protected by this invention, by setting up a horizontal cleaning channel, a cleaning unit, and a drying unit, can achieve both cleaning and overall drying of the wheels of vehicles to be cleaned. The vehicle enters the cleaning channel from the inlet, has its wheels cleaned by the cleaning unit, and then is dried by the drying unit before exiting the cleaning channel from the outlet. The cleaning belt in the cleaning unit continuously and repeatedly scrubs the dirt off the wheels. After scrubbing, the wheels enter the drying section, where a warm air device dries the cleaned vehicle, which rests on the support plate. The dried vehicle then exits the cleaning device from the outlet. This device has a simple structure, does not require lifting the vehicle during cleaning, has high cleaning efficiency, high safety performance, low requirements for positioning accuracy, excellent cleaning effect, and self-cleaning capability.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
