Technical Field

The invention belongs to an automatic production line of aluminum alloy hubs, is used for automatically positioning and identifying hubs through a logistics raceway so as to facilitate the processing of subsequent machine tools, and particularly relates to a feeding positioning and identifying system of aluminum alloy hubs.

Background

The automobile hub is mainly made of aluminum alloy, and cast molding occupies a main position, compared with the steel automobile hub, the aluminum alloy hub has small density which is about 1/3 of steel, so that the whole automobile quality of the automobile can be reduced, the fuel efficiency is improved, and the automobile hub has important significance for energy conservation, emission reduction and low-carbon life. Meanwhile, the aluminum alloy hub has the advantages of heat dissipation performance superior to that of a steel hub, easiness in machining and forming, small deformation during high-speed rotation, small inertial resistance and the like, and is popular among multiple vehicle owners. The wheel hub processed by the numerical control machine tool has high dimensional precision and roundness, small deflection and bounce and good balance, so that the automobile runs stably and comfortably.

The production method of the aluminum alloy wheel hub mainly comprises a casting method, a forging method, a stamping method, a spinning method and the like. After the hub is machined and formed, the hub needs to be subsequently machined, and due to the enlargement of modern production, a hub workshop often needs to process hubs of more than ten types or even more than ten types. Consequently on processing aluminum alloy wheel hub's automatic production line, realize automatic transport, carry the location with the commodity circulation raceway to effectively discern the wheel hub model, with the accurate processing of realizing wheel hub, be indispensable production processes. At present, a two-dimensional code technology is adopted to identify a hub, so that subsequent processing is performed, for example, chinese patents CN201710105129.2, CN201910044801.0, CN201721296325.4 and the like all adopt a roller way to transport the hub, and a two-dimensional code scanning device is used to scan and identify a two-dimensional code on the hub, or mark the two-dimensional code. However, when the device is used for identification, the two-dimensional code scanning device is arranged below the roller way, and meanwhile, the two-dimensional code at the bottom of the hub is scanned and identified. The two-dimensional code scanning device has certain production process limitations, if the two-dimensional code is shielded by the roller way, the two-dimensional code is difficult to identify, and meanwhile, the scanning gun is limited to be only installed below the roller way, so that the design of a transportation structure is limited. The above process is still imperfect.
