Description

Device and method for air-drying hub after cleaning Technical Field The invention relates to the technical field of hub air drying, in particular to an air drying device and method after hub cleaning. Background In the manufacturing process of the automobile hub, after the hub is polished by a polishing machine, a large amount of polishing liquid residues and aluminum powder impurities adhere to the surface of the hub, and if the impurities are directly carried into the subsequent coating and detection processes, the problems of reduced coating adhesion, deviation of detection precision and the like are caused, so that the impurities on the surface must be removed through a plurality of cleaning processes. The surface of the hub after being cleaned can remain a large amount of water drops and thin water films, the requirements of the subsequent coating, airtight detection and other procedures on the cleanliness of the surface of the hub are extremely high, the surface moisture is required to be completely removed, no water mark and no impurity residue are required, and the final quality of the product is seriously affected. At present, two traditional processes are mainly adopted for dewatering and air drying of the hub after cleaning in the industry. The first mode is that the manual hand-held air pipe is dried by compressed air, and the mode needs an operator to sweep the parts such as the surface of the wheel hub, the gaps of the spokes, the inner ring and the like one by the hand-held air pipe. The hub is complex in structure, more curved surfaces and dead angles exist, full coverage is difficult to ensure due to manual blowing, partial area moisture remains, meanwhile, the mode is extremely high in compressed air consumption and serious in energy waste, noise generated in the blowing process is high, the operation environment is not safe enough, in addition, the consistency of manual operation is poor, the time for blowing and drying a single hub is long, the production efficiency is low, and the beat requirement of an automatic production line cannot be adapted completely. The second process adopts a high-power hot air blower to carry out high-temperature drying, and the surface of the hub is heated by high-temperature air flow, so that residual moisture is evaporated to realize drying. The process has the obvious technical defects that water vapor generated by high-temperature evaporation cannot be timely discharged, part of the water vapor can be condensed on the surface of the hub, mineral substances contained in water can be adhered to the surface of the hub along with water evaporation and crystallization to form water stain marks which are difficult to remove, the water stain mark rate of the hub treated by the process is as high as 20%, the process requirements can be met only by manual secondary wiping, the labor cost and the labor hour consumption are additionally increased, meanwhile, the high-power hot air machine is high in operation energy consumption, the high-temperature air flow is easy to cause slight damage to the polished surface of the hub, and the appearance accuracy of products is affected. Disclosure of Invention The present invention has been made in view of the above problems, and it is an object of the present invention to provide a post-cleaning air-drying apparatus and method for a hub that overcomes or at least partially solves the above problems. In a first aspect, an embodiment of the present invention provides a post-cleaning air-drying apparatus for a hub, including: The device comprises a control unit, a conveying unit, a protection unit and an air knife blowing unit; The control unit comprises a controller, the protection unit comprises an outer cover and a grating ruler, the air knife blowing unit comprises a blowing mechanism, the outer cover is provided with an inlet and an outlet, the grating ruler is arranged at the inlet and the outlet of the outer cover, the blowing mechanism is arranged on the outer cover, and the controller is electrically connected with the conveying unit, the grating ruler and the blowing mechanism; The grating ruler is used for sensing the position information of the hub and feeding the position information of the hub back to the controller; The controller is used for controlling the conveying unit to convey the hub to the inlet and outlet of the outer cover, receiving the hub position information fed back by the grating ruler, judging whether the hub is conveyed to a preset position according to the hub position information, and if yes, controlling the blowing mechanism to blow and air-dry the hub. In one embodiment, the hub post-cleaning air drying device further comprises a righting mechanism, wherein the righting mechanism is arranged on the outer cover; the controller is electrically connected with the righting mechanism; The controller is also used for controlling the righting mechanism to clamp the hub after the controller judges t
