[0019] As used herein, the phrase "one embodiment" or "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearances of the phrase "in one embodiment" in various places in the specification do not necessarily refer to the same embodiment.

[0020] As Figures 1 to 8 shown, the present invention discloses a spoke cleaning system for cleaning a spoke 400, which includes a feeding conveyor 110, a discharging conveyor 210, a first cleaning machine 120, a second cleaning machine 220, a first robot 130, and a second robot 230. The first cleaning machine 120 and the second cleaning machine 220 are both provided with a first loading and unloading station 121, a cleaning station 122, and a second loading and unloading station 123. Loading jigs for loading the spoke 400 are provided on both the first cleaning machine 120 and the second cleaning machine 220. The loading jig can reciprocate between the first loading and unloading station 121 and the cleaning station 122 or between the second loading and unloading station 123 and the cleaning station 122. A cleaning device for cleaning the spoke 400 is provided in the cleaning station 122. The first cleaning machine 120 and the second cleaning machine 220 are respectively used for cleaning the convex surface and the concave surface of the spoke 400. The convex surface and the concave surface of the spoke 400 are symmetric complementary curved surfaces and together form the outer contour surface of the spoke 400. The first robot 130 is used to move the spoke 400 located on the feeding conveyor 110 to the first loading and unloading station 121 or the second loading and unloading station 123 of the first cleaning machine 120. The second robot 230 is used to turn over the spoke 400 located on the first loading and unloading station 121 or the second loading and unloading station 123 of the first cleaning machine 120 and move it to the loading jig on the first loading and unloading station 121 or the second loading and unloading station 123 of the second cleaning machine 220. As Figure 6 、 7As shown, except for the loading fixtures, the first cleaning machine 120 and the second cleaning machine 220 in this embodiment are set to have the same structure. When the loading fixture of the first cleaning machine 120 is loading the wheel spoke 400, the convex surface of the wheel spoke 400 faces the jet orifice of the cleaning device. When the loading fixture 124 of the second cleaning machine 220 is loading the wheel spoke 400, the concave surface of the wheel spoke 400 faces the jet orifice of the cleaning device, so that the first cleaning machine 120 and the second cleaning machine 220 can respectively complete the cleaning of the convex surface and the concave surface of the wheel spoke 400. It should be noted that the first cleaning machine 120 and the second cleaning machine 220 in this embodiment are not intended to limit the specific structure of the cleaning machine, but are only used to conveniently describe a cleaning machine in the cleaning system, in which two loading fixtures respectively face the concave surface and the convex surface of the wheel spoke 400 towards the jet orifice of the cleaning device. In this embodiment, the first robot 130 and the second robot 230 are also set to have the same structure, and are both used to grasp the wheel spoke 400 and complete the transfer of the wheel spoke 400 between different devices. Specifically, when the feeding conveyor 110 conveys the wheel spoke 400 to the docking position with the first cleaning machine 120, the first robot 130 moves the wheel spoke 400 from the feeding conveyor 110 to the loading fixture of the first cleaning machine 120 and completes the loading of the wheel spoke 400, so that the wheel spoke 400 is fixed on the loading fixture of the first cleaning machine 120. When the loading fixture of the first cleaning machine 120 moves to the second loading and unloading station 123, the second robot 230 removes the wheel spoke 400 from the loading fixture of the first robot 130, turns the wheel spoke 400 over, and loads it onto the loading fixture of the second cleaning machine 220 at the first loading and unloading station 121, completing the loading of the wheel spoke 400 on the second cleaning machine 220. At the same time, the second robot 230 is also used to remove the wheel spoke 400 from the loading fixture and move it to the discharging conveyor 210 when the loading fixture of the second cleaning machine 220 moves to the second loading and unloading station 123. In other embodiments, the wheel spoke cleaning system further includes a third robot, and the second robot 230 is only used to complete the transfer and turning over of the wheel spoke 400 between the first cleaning machine 120 and the second cleaning machine 220, and the third robot is used to complete the transfer of the wheel spoke 400 from the second cleaning machine 220 to the discharging conveyor 210.

[0021] Specifically, in some embodiments, the loading fixture includes a first loading fixture and a second loading fixture. The first loading fixture can reciprocate between a first loading and unloading station 121 and a cleaning station 122. The second loading fixture can reciprocate between a second loading and unloading station 123 and the cleaning station 122. And the first loading fixture and the second loading fixture move synchronously. When the first loading fixture moves from the first loading and unloading station 121 to the cleaning station 122, the second loading fixture moves from the cleaning station 122 to the second loading and unloading station 123. The spokes 400 loaded on the first loading fixture and the second loading fixture alternately move into the cleaning station 122 to complete the cleaning operation.

[0022] In this technical solution, the feed conveyor device 110 and the discharge conveyor device 210 are used to horizontally convey the spokes 400. The loading fixture 124 is used to horizontally load the spokes 400 and carry the spokes 400 to move between the first loading and unloading station 121, the cleaning station 122 and the second loading and unloading station 123 of the first cleaning machine 120 and the second cleaning machine 220. When the spoke 400 moves to the cleaning station 122, the cleaning device cleans the spoke 400. The first cleaning machine 120 and the second cleaning machine 220 respectively clean the convex surface and the concave surface of the spoke 400, that is, the outer contour surface of the entire spoke 400 is cleaned through two cleaning processes. The first robot 130 and the second robot 230 complete the handover of the spoke 400 between the devices in the cleaning system, and the second robot 230 flips the spoke 400 to realize the automation of the entire cleaning process of the spoke 400. By cleaning the two sides of the spoke 400 separately, the cleaning effect of the spoke 400 is improved, and the operation stability of each device during the cleaning process is good.

[0023] In some embodiments, as Figure 6 , 7 shown, the first cleaning machine 120 is used to clean the convex surface of the spoke 400, and the second cleaning machine 220 is used to clean the concave surface of the spoke 400. It should be noted that, in some preferred embodiments, as Figure 8As shown, the first cleaning machine 120 is used to clean the concave surface of the wheel spoke 400, and the second cleaning machine 220 is used to clean the convex surface of the wheel spoke 400. That is, first, the concave surface of the wheel spoke 400 is cleaned by the first cleaning machine 120, then the convex surface of the wheel spoke is cleaned by the second cleaning machine 220. Then, the second robot 230 moves the wheel spoke 400 to the immersion cleaning device 500 with the convex surface facing up for immersion cleaning. After the immersion cleaning device 500 removes the oxides adhered to the surface of the wheel spoke 400, the wheel spoke 400 is sent into the discharge conveying device 210 by the pushing mechanism, and after being air-dried by the air-drying component on the discharge conveying device 210, it is moved to the designated position. First, the concave surface of the wheel spoke 400 is cleaned, then the convex surface of the wheel spoke 400 is cleaned, and the wheel spoke 400 is placed in the immersion liquid pool with the convex surface facing up for immersion cleaning, preventing the oxides adhered to the surface of the wheel spoke 400 from staying in the bottom cavity of the concave surface during immersion cleaning (when the concave surface faces up for immersion cleaning, the oxides adhered to the surface of the wheel spoke 400 are likely to stay in the bottom cavity of the concave surface). Cleaning the concave surface first and then the convex surface can reduce the step of turning over the wheel spoke, resulting in better cleaning effect.

[0024] As Figure 8 shown, the immersion cleaning device 500 includes a liquid pool, a grid plate, and a pushing mechanism. The grid plate is used to support the wheel spoke 400 and can reciprocate in the vertical direction so that the wheel spoke 400 can be immersed in the liquid pool located below the grid plate. The pushing mechanism is horizontally arranged with the grid plate and is located above the grid plate. After the cleaning of the wheel spoke 400 is completed, the pushing mechanism can push the wheel spoke 400 from the grid plate into the discharge conveying device 210.

[0025] In some embodiments, as Figure 4 shown, the first cleaning machine 120 and the second cleaning machine 220 are also provided with a working chamber 125. The cleaning station 122 is located inside the working chamber 125. The first loading and unloading station 121 and the second loading and unloading station 123 are respectively located outside both sides of the working chamber 125. The working chamber 125 includes a sandblasting cleaning chamber 1251 in the middle section and water spraying and rinsing chambers 1252 on both sides of the sandblasting cleaning chamber 1251. A sandblasting pipeline 126 is arranged inside the sandblasting cleaning chamber 1251, and the sandblasting pipeline 126 is connected to a turbine 127. A water spraying pipeline 128 is arranged inside the water spraying and rinsing chamber 1252, and the water spraying pipeline 128 is connected to a water supply pipeline. The water spraying pipeline 128 includes water outlet nozzles, and the sandblasting pipeline 126 includes sandblasting nozzles. The water spraying and rinsing chambers 1252 on both sides of the sandblasting cleaning chamber 1251 are respectively mainly used to rinse the wheel spoke 400 before and after sandblasting cleaning to remove the solid particles attached to the surface of the wheel spoke 400, and the sandblasting cleaning chamber 1251 is used to impact and remove the oxide layer on the surface of the wheel spoke 400 by the mortar flow sprayed by the turbine 127.

[0026] In some embodiments, as Figures 4 to 6 shown, a partition 310 is provided between the sandblasting cleaning chamber 1251 and the water spraying rinsing chamber 1252. A door opening 320 is formed in the partition 310. Door openings 320 with the same shape are also formed between the water spraying cleaning chamber and the first loading and unloading station 121 and the second loading and unloading station 123. The loading fixture is arranged on a moving guide rail 330, and a baffle 340 that moves synchronously with the loading fixture is further arranged on the moving guide rail 330. The baffle 340 fits with the door opening 320. The partition 310 and the baffle 340 are used to prevent water flow and steel sand from splashing out during sandblasting cleaning and water spraying cleaning, improve the safety of the operation and reduce pollution. Specifically, four door openings are formed, and six partitions are provided. When any one of the first loading fixture and the second loading fixture is located in the sandblasting cleaning chamber 1251, four of the baffles 340 are respectively located at the four door openings 320 and cooperate with the corresponding door openings 320 to isolate the working chamber 125 from the outside, and the sandblasting cleaning chamber 1251 and the water spraying rinsing chamber 1252 inside the working chamber 125 are also isolated from each other. For example, the first loading fixture is located on one side of the moving guide rail, the second loading fixture is located on the other side of the moving guide rail, and six baffles 340 are symmetrically arranged on the moving guide rail. When the first loading fixture is located at the cleaning station 122, the four baffles 340 close to the first loading fixture cooperate with the door openings 320 to close the door openings 320, and the two baffles close to the second loading fixture are located outside the working chamber 125 (together with the second loading fixture in the second loading and unloading station 123); conversely, when the second loading fixture is located at the cleaning station 122, the four baffles 340 close to the second loading fixture cooperate with the door openings 320 to close the door openings 320, and the two baffles close to the first loading fixture are located outside the working chamber 125 (together with the first loading fixture in the first loading and unloading station 121).

[0027] In some embodiments, as Figure 1As shown, the working chamber 125 further includes a negative pressure collection device 350, which is used to collect water vapor in the working chamber 125. The negative pressure collection and loading device 350 is also connected to a vapor collection device 351 through a pipeline. The negative pressure collection device 350 is used to provide negative pressure to cause the water vapor to gather in the pipeline where the negative pressure collection device 350 is located. The vapor collection device 351 is used to adsorb and collect the water vapor and make it form a liquid state. An adsorbent is provided inside the vapor collection device 351, and the adsorbent can be set as a material that can adsorb water vapor, such as quicklime. A filter screen is also provided in the pipeline of the negative pressure collection device 350. Specifically, the negative pressure collection device 350 is connected to the inside of the working chamber 125 through a pipeline. A filter screen is provided in the pipeline of the negative pressure collection device 350 to prevent solid particles from entering the negative pressure collection device 350 and damaging the device. During the cleaning process of the spoke 400, a large amount of water mist will be generated. In order to avoid water vapor polluting the working environment, negative pressure is generated by the negative pressure collection device 350 to pump the water vapor in the working chamber 125 into the collection device. By setting a filter screen in the pipeline, solid particles such as steel sand and scale are blocked from entering the pipeline of the negative pressure collection device 350 and the vapor collection device 351.

[0028] In some embodiments, as Figure 2 , 6 shown, a water tank 360 and a water storage tank 370 are provided at the bottom of the working chamber 125. The water tank 360 is used to recover the mortar flow and store steel sand, and the water storage tank 370 is used to store the working fluid. The turbine 127 is connected to an injector through a pipeline. The injector is used to mix the steel sand inhaled from the water tank 360 and the working fluid pumped from the water storage tank 370 to form a mortar flow and input it into the turbine 127. Specifically, while the injector pumps the working fluid from the water storage tank 370, it inhales steel sand particles from the water tank 360, mixes the two to form mortar, and inputs it to the impeller of the turbine 127. The impeller of the turbine 127 sprays the mortar at high speed rotation and performs sandblasting and rust removal on the surface of the spoke 400. After the mortar flow hits the surface of the spoke 400, it falls into the water tank 360 at the bottom of the working chamber 125 under the action of gravity and spraying.

[0029] In some embodiments, the water tank 360 is connected to the water storage tank 370 through a pipeline, and a magnetic separator 380 is also provided in the pipeline between the water storage tank 370 and the water tank 360. After the mortar flow falls into the water tank 360 at the bottom of the working chamber 125, it precipitates in the water tank 360. After precipitation, the steel sand particles fall to the bottom of the water tank 360. Solid particulate matters such as iron sludge washed out from the surface of the spoke 400 are filtered and separated from the working fluid through the magnetic separator 380, and the filtered and separated working fluid is pumped back into the water storage tank 370, completing the recycling of the working fluid and steel sand.

[0030] In some embodiments, such as Figure 1 , 2 shown, the water tank 360 is also connected to a sludge recovery device 390 through a pipeline. The sludge recovery device 390 is used to recover the iron sludge in the water tank 360. The sludge recovery device 390 is also connected to a sludge transport vehicle 391. The sludge transport vehicle 391 is used to pick up the sludge output by the sludge recovery device 390 and transport it to a target location. Specifically, the sludge recovery device 390 is set as a sludge discharge screw. The sludge discharge screw is connected to the magnetic separator 380 through a pipeline. Solid particles such as iron sludge separated by the magnetic separator 380 enter the sludge discharge screw through the pipeline. The sludge discharge screw discharges the sludge from the pipeline through a rotational force, and then the sludge transport vehicle 391 picks up the sludge discharged by the sludge discharge screw, thereby completing the sludge recovery operation.

[0031] In some embodiments, such as Figure 1 , 2 shown, the first robot 130 and the second robot 230 are set as robotic arms and manipulators. The manipulator is arranged on the robotic arm, and the manipulator is used to grasp the wheel hub 400.

[0032] In some embodiments, such as Figure 1 shown, both the feeding conveyor device 110 and the discharging conveyor device 210 are set as conveyor belts or conveyor rollers. A drying component is also arranged on the discharging conveyor device 210. As a implementation method, the feeding conveyor device 110 and the discharging conveyor device 210 in this embodiment are set as conveyor rollers. The wheel hub 400 is horizontally placed on the conveyor rollers and moves along the conveying direction of the conveyor rollers. A drying component is also arranged on the discharging device. The drying component can be arranged in the surrounding space of the conveyor rollers. The drying component can be a fan arranged at the bottom or above the conveyor rollers. The fan dries the wheel hub 400 after cleaning on the conveyor rollers.

[0033] In this embodiment, the specific working steps of the wheel spoke cleaning system are as follows: first, the wheel spoke 400 is placed on the feeding conveying device 110, and the feeding conveying device 110 conveys the wheel spoke 400 to a position docking with the first feeding and unloading station 121 of the first cleaning machine 120. The first robot 130 grabs the wheel spoke 400 on the feeding conveying device 110 and moves and loads it onto the loading fixture of the first feeding and unloading station 121 of the first cleaning machine 120. At this time, the convex surface of the wheel spoke 400 faces upward. After the loading of the wheel spoke 400 is completed, the loading fixture of the first cleaning machine 120 is driven by the driving device to move from the first feeding and unloading station 121 to the cleaning station 122 along the moving guide rail 330. The water spray pipe 128 in the first water spray flushing bin 1252 sprays water to flush the wheel spoke 400, and the water outlet nozzle position of the sandblasting pipe 126 Above the spoke 400, the sandblasting pipeline 126 (sandblasting nozzle) in the sandblasting cleaning chamber 1251 sprays slurry flow to sandblast the spoke 400. After the sandblasting cleaning is completed, the loading fixture carries the spoke 400 to the second water spraying flushing chamber 1252, and the water spraying pipeline 128 in the second water spraying flushing chamber 1252 sprays water on the spoke 400 again. After the flushing is completed, the loading fixture moves the spoke 400 to the second loading and unloading station 123, and the above is completed. The cleaning of the convex surface of the spoke 400 is completed; the second robot 230 removes the spoke 400 loaded on the loading fixture of the first cleaning machine 120, and turns it over and loads it onto the loading fixture of the second robot 230 located at the first loading and unloading station 121. At this time, the spoke 400 is on the loading fixture of the second cleaning machine 220. The concave surface faces upward (such as Figure 7 In the state shown), the second cleaning machine 220 repeats the cleaning steps of the first cleaning machine 120 to complete the cleaning of the concave surface of the spoke 400. When the second cleaning machine 220 completes the cleaning and moves to the second loading and unloading station 123, the second robot 230 removes the spoke 400 from the loading fixture of the second cleaning machine 220 and places it on the discharging conveying device 210. The discharging conveying device 210 air-dries the spoke 400 and conveys it to the designated position. At this point, the entire cleaning process of the spoke 400 is completed.

[0034] To summarize, in this embodiment, the convex and concave surfaces of the spoke 400 are cleaned respectively by the first cleaning machine 120 and the second cleaning machine 220, the handover of the spoke 400 between the various devices in the cleaning system is completed by the first robot 130 and the second robot 230, and the turning over of the spoke 400 is completed by the second robot 230, so as to realize the automation of the entire cleaning process of the spoke 400, and the cleaning effect of the spoke 400 is improved by cleaning the spoke 400 on one side twice, and the operation stability of each device is good during the cleaning process.

[0035] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the content described in the drawings and the above specific implementation manner.
