[0030] like Figures 1 to 8As shown, the present invention discloses a spoke cleaning system for cleaning spokes 400, comprising a feeding conveying device 110, a discharging conveying device 210, a first cleaning machine 120, a second cleaning machine 220, a first robot 130 and a second robot 230, wherein the first cleaning machine 120 and the second cleaning machine 220 are both provided with a first feeding and discharging station 121, a cleaning station 122 and a second feeding and discharging station 123, and the first cleaning machine 120 and the second cleaning machine 220 are both provided with a loading fixture for loading the spokes 400, and the loading fixture can circulate back and forth between the first feeding and discharging station 121 and the cleaning station 122 or the second feeding and discharging station 123 and the cleaning station 122, and the cleaning station 122 is provided with a loading fixture for cleaning The cleaning device of the spoke 400; the first cleaning machine 120 and the second cleaning machine 220 are respectively used to clean the convex surface and concave surface of the spoke 400, and the convex surface and concave surface of the spoke 400 are symmetrical complementary curved surfaces and together constitute the outer contour surface of the spoke 400; the first robot 130 is used to move the spoke 400 located on the feeding and conveying device 110 to the first loading and unloading station 121 or the second loading and unloading station 123 of the first cleaning machine 120, and 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 fixture of the first loading and unloading station 121 or the second loading and unloading station 123 of the second cleaning machine 220. Figure 6 、 7As shown, in this embodiment, the first cleaning machine 120 and the second cleaning machine 220 have the same structure except for the loading fixture. When the loading fixture of the first cleaning machine 120 is loaded with the spoke 400, the convex surface of the spoke 400 faces the jet outlet of the cleaning device. When the loading fixture 124 of the second cleaning machine 220 is loaded with the spoke 400, the concave surface of the spoke 400 faces the jet outlet of the cleaning device, so that the first cleaning machine 120 and the second cleaning machine 220 respectively complete the cleaning of the convex and concave surfaces of the spoke 400. It should be noted that the first cleaning machine 120 and the second cleaning machine 220 in this embodiment do not limit the specific structure of the cleaning machine, but are only used to conveniently describe a cleaning system including two cleaning machines with loading fixtures that respectively direct the concave and convex surfaces of the spoke 400 toward the jet outlet of the cleaning device. In this embodiment, the first robot 130 and the second robot 230 are also configured to have the same structure, and are both used to grab the spoke 400 and complete the handover of the spoke 400 between different devices. Specifically, when the feeding conveying device 110 conveys the spoke 400 to the docking position with the first cleaning machine 120, the first robot 130 moves the spoke 400 from the feeding conveying device 110 to the loading fixture of the first cleaning machine 120, and completes the loading of the spoke 400, so that the spoke 400 is fixed on the loading fixture of the first cleaning machine 120. The second robot When the loading fixture of the first cleaning machine 120 moves to the second loading and unloading station 123, the first robot 230 removes the spoke 400 from the loading fixture of the first robot 130, flips the spoke 400 over, and loads it onto the loading fixture of the second cleaning machine 220 located at the first loading and unloading station 121, completing the loading of the spoke 400 onto the second cleaning machine 220. Simultaneously, the second robot 230 is also used to remove the spoke 400 from the loading fixture and move it to the discharge 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 spoke cleaning system further includes a third robot, in which case the second robot 230 is only used to complete the transfer and flipping of the spoke 400 from the first cleaning machine 120 to the second cleaning machine 220, while the third robot is used to complete the transfer of the spoke 400 from the second cleaning machine 220 to the discharge conveyor 210.

[0031] Specifically, in some embodiments, the loading fixture includes a first loading fixture and a second loading fixture, the first loading fixture can move back and forth between the first loading and unloading station 121 and the cleaning station 122, the second loading fixture can move back and forth between the 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, and the spokes 400 loaded on the first loading fixture and the second loading fixture move alternately into the cleaning station 122 to complete the cleaning operation.

[0032] In the present technical solution, the spokes 400 are horizontally transferred by the feeding conveyor 110 and the discharging conveyor 210, and the spokes 400 are horizontally loaded by the loading fixture 124 and carried to move between the first feeding and discharging station 121, the cleaning station 122 and the second feeding and discharging station 123 of the first cleaning machine 120 and the second cleaning machine 220. When the spokes 400 are moved to the cleaning station 122, the cleaning device cleans the spokes 400. The spokes 400 are separated by the first cleaning machine 120 and the second cleaning machine 220. The convex and concave surfaces of the spoke 400 are cleaned separately, 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 various devices in the cleaning system, and the second robot 230 completes the turning over of the spoke 400 to realize the automation of the entire spoke 400 cleaning process, and the cleaning effect of the spoke 400 is improved by cleaning the spoke 400 twice on one side, and the operation stability of each device is good during the cleaning process.

[0033] In some embodiments, as Figure 6 、 7 As 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, Figure 8As shown, the first cleaning machine 120 is used to clean the concave surface of the spoke 400, and the second cleaning machine 220 is used to clean the convex surface of the spoke 400, that is, the concave surface of the spoke 400 is first cleaned by the first cleaning machine 120, and then the convex surface of the spoke is cleaned by the second cleaning machine 220, and then the second robot 230 moves the spoke 400 with the convex surface facing up to the immersion device 500 for immersion cleaning. The immersion device 500 removes the oxides adhered to the surface of the spoke 400 and then sends the spoke 400 into the discharge conveying device 210 through the pushing mechanism, and is air-dried by the air-drying component on the discharge conveying device 210 and moved to the designated position. The concave surface of the spoke 400 is cleaned first, and then the convex surface of the spoke 400 is cleaned, and the spoke 400 is placed in the immersion liquid pool for immersion with the convex surface facing upward to prevent the oxide adhered to the surface of the spoke 400 from staying in the bottom cavity of the concave surface during immersion (when immersing with the concave surface facing upward, the oxide adhered to the surface of the spoke 400 is likely to stay in the bottom cavity of the concave surface during immersion). Cleaning the concave surface first and then the convex surface can reduce the step of turning the spoke over, thereby achieving better cleaning effect.

[0034] like Figure 8 As shown, the immersion device 500 includes a liquid pool, a grid plate and a pushing mechanism. The grid plate is used to support the spoke 400 and can reciprocate in the vertical direction so that the spoke 400 can be immersed in the liquid pool below the grid plate. The pushing mechanism is arranged horizontally with the grid plate and is located above the grid plate. After the spoke 400 is cleaned, the pushing mechanism can push the spoke 400 from the grid plate to the discharge conveying device 210.

[0035] In some embodiments, as Figure 4 As shown, the first cleaning machine 120 and the second cleaning machine 220 are also provided with a working bin 125, the cleaning station 122 is located in the working bin 125, the first loading and unloading station 121 and the second loading and unloading station 123 are respectively located outside the two sides of the working bin 125, and the working bin 125 includes a sandblasting cleaning bin 1251 located in the middle section and a water spraying flushing bin 1252 located on both sides of the sandblasting cleaning bin 1251. A sandblasting pipeline 126 is provided in the sandblasting cleaning bin 1251, and the sandblasting pipeline 126 is connected to a turbine 127. A water spraying pipeline 128 is provided in the water spraying flushing bin 1252, and the water spraying pipeline 128 is connected to a water supply pipe. The water spray pipe 128 includes a water outlet nozzle, the sandblasting pipe 126 includes a sandblasting nozzle, and the water spray flushing chamber 1252 located on both sides of the sandblasting cleaning chamber 1251 is mainly used to flush the spokes 400 before and after sandblasting cleaning to remove solid particles attached to the surface of the spokes 400. The sandblasting cleaning chamber 1251 is used to remove the oxide layer on the surface of the spokes 400 by the slurry flow ejected by the turbine 127.

[0036] In some embodiments, as Figures 4 to 6 As shown, a partition 310 is provided between the sandblasting chamber 1251 and the water jet cleaning chamber 1252. A doorway 320 is defined in the partition 310. Doorways 320 of the same shape are also defined between the water jet cleaning chamber and the first and second loading and unloading stations 121, 123. The loading fixture is mounted on a movable guide rail 330. A baffle 340 is also provided on the movable guide rail 330, which moves synchronously with the loading fixture and mates with the doorway 320. The partition 310 and baffle 340 are used to prevent water and steel grit from splashing during sandblasting and water jet cleaning, improving operational safety and reducing pollution. Specifically, there are four door openings and six partitions. When any one of the first loading fixture and the second loading fixture is located in the sandblasting cleaning chamber 1251, the four 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 washing 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, and the second loading fixture is located on the other side of the moving guide rail. Six baffles 340 are symmetrically arranged on the moving guide rail. When the loading fixture is located in the cleaning station 122, the four baffles 340 close to the first loading fixture cooperate with the door opening 320 to close the door opening 320, and the two baffles close to the second loading fixture are located outside the working bin 125 (located in the second loading and unloading station 123 together with the second loading fixture); conversely, when the second loading fixture is located in the cleaning station 122, the four baffles 340 close to the second loading fixture cooperate with the door opening 320 to close the door opening 320, and the two baffles close to the first loading fixture are located outside the working bin 125 (located in the first loading and unloading station 121 together with the first loading fixture).

[0037] In some embodiments, as Figure 1As shown, the working chamber 125 also includes a negative pressure collecting device 350, which is used to collect water vapor in the working chamber 125. The negative pressure collecting device 350 is also connected to a steam collecting device 351 through a pipeline. The negative pressure collecting device 350 is used to provide negative pressure to make water vapor gather in the pipeline where the negative pressure collecting device 350 is located. The steam collecting device 351 is used to adsorb and collect water vapor and form it into a liquid state. An adsorbent is provided inside the steam collecting device 351, and the adsorbent can be set to a material that can adsorb water vapor such as quicklime. A filter is also provided in the pipeline of the negative pressure collecting device 350. Specifically, the negative pressure collection device 350 is connected to the interior of the working chamber 125 through a pipe. A filter is provided in the pipe of the negative pressure collection device 350 to prevent solid particles from entering the negative pressure collection device 350 and damaging the device. A large amount of water mist will be generated during the cleaning process of the spokes 400. In order to avoid water vapor polluting the working environment, negative pressure is generated by the negative pressure collection device 350 to draw the water vapor in the working chamber 125 into the collection device. By providing a filter in the pipe, solid particles such as steel sand and oxide scale are prevented from entering the pipe of the negative pressure collection device 350 and entering the steam collection device 351.

[0038] In some embodiments, as Figure 2 、 6 As shown, a water trough 360 and a water storage tank 370 are provided at the bottom of the working chamber 125. The water trough 360 is used to recover the mortar flow and store steel grit, and the water storage tank 370 is used to store working fluid. A pipe connecting the turbine 127 is connected to an ejector. The ejector is used to mix the steel grit drawn from the water trough 360 with the working fluid pumped from the water storage tank 370 to form a mortar flow, which is then input into the turbine 127. Specifically, the ejector simultaneously pumps working fluid from the water storage tank 370 and draws steel grit particles from the water trough 360. The mixed mortar is then input into the impeller of the turbine 127. The impeller of the turbine 127 rotates at high speed, ejecting the mortar to sandblast and remove rust from the surface of the spokes 400. After impacting the surface of the spokes 400, the mortar flow falls into the water trough 360 at the bottom of the working chamber 125 due to gravity and the ejection action.

[0039] In some embodiments, the water tank 360 is connected to a water storage tank 370 through a pipeline, and a magnetic separator 380 is further provided in the pipeline between the water storage tank 370 and the water tank 360. The slurry flow falls into the water tank 360 at the bottom of the working chamber 125 and settles there. After settling, the steel grit particles fall to the bottom of the water tank 360. Solid particles such as iron sludge cleaned from the surface of the spokes 400 are filtered and separated from the working fluid by the magnetic separator 380. The filtered and separated working fluid is then pumped back to the water storage tank 370, completing the recycling of the working fluid and steel grit.

[0040] In some embodiments, as Figure 1 、 2 As 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 receive the sludge output by the sludge recovery device 390 and transport it to the target location. Specifically, the sludge recovery device 390 is configured as a mud discharge screw. The mud discharge screw pipeline is connected to the magnetic separator 380. The iron sludge and other solid particles separated by the magnetic separator 380 enter the mud discharge screw through the pipeline. The mud discharge screw discharges the sludge from the pipeline through the rotational force. The sludge discharged by the mud discharge screw is then received by the sludge transport vehicle 391, thereby completing the sludge recovery operation.

[0041] In some embodiments, as Figure 1 、 2 As shown, the first robot 130 and the second robot 230 are configured as a robotic arm and a robotic hand, the robotic hand is provided on the robotic arm, and the robotic hand is used to grasp the spoke 400 .

[0042] In some embodiments, as Figure 1 As shown, the feed conveyor 110 and the discharge conveyor 210 are both configured as conveyor belts or conveyor rollers, and the discharge conveyor 210 is further provided with an air-drying assembly. As an implementation method, the feed conveyor 110 and the discharge conveyor 210 of this embodiment are configured as conveyor rollers, and the spokes 400 are horizontally placed on the conveyor rollers and move along the conveying direction of the conveyor rollers. The discharge conveyor is further provided with an air-drying assembly, which can be positioned in the space surrounding the conveyor rollers. The air-drying assembly can be a fan positioned at the bottom or above the conveyor rollers, which uses the fan to air-dry the spokes 400 on the conveyor rollers after cleaning.

[0043] In this embodiment, the specific working steps of the spoke cleaning system are as follows: first, the spoke 400 is placed on the feeding conveying device 110, and the feeding conveying device 110 conveys the spoke 400 to the position docking with the first loading and unloading station 121 of the first cleaning machine 120. The first robot 130 grabs the spoke 400 on the feeding conveying device 110 and moves and loads it onto the loading fixture of the first loading and unloading station 121 of the first cleaning machine 120. At this time, the convex surface of the spoke 400 faces upward. After the loading of the spoke 400 is completed, the loading fixture of the first cleaning machine 120 is driven by the driving device and moves along the moving guide rail 330 from the first loading and unloading station 121 to the cleaning station 122. The water spray pipe 128 in the first water spray washing bin 1252 sprays water to wash the spoke 400, and the water outlet nozzle position of the sandblasting pipe 126 is Above the spoke 400, the sandblasting pipe 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 washing chamber 1252, and the water spraying pipe 128 in the second water spraying washing chamber 1252 sprays water on the spoke 400 again. After the washing 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 with the concave surface facing up (as shown in FIG. Figure 7 As shown in the state, 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 discharge conveying device 210. The discharge conveying device 210 then air-dries the spoke 400 and conveys it to the designated position. At this point, the entire spoke 400 cleaning process is completed.

[0044] To sum up, 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 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 twice on one side, and the operation stability of each device is good during the cleaning process.
