Description

An online intelligent weighing device for aluminum alloy wheel hubs Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel production technology, specifically to an online intelligent weighing device for aluminum alloy wheel hubs. Background Technology

[0002] The main forming processes for aluminum alloy wheels include low-pressure casting, casting and spinning, and forging. Currently, aluminum alloy wheels are being used more and more widely. Unlike steel wheels, the primary design purpose of aluminum alloy wheels, besides aesthetics, is to reduce the overall weight of the vehicle. However, as a safety component, they cannot be too light and must meet design requirements. Therefore, the weight of the product needs to be monitored during the production process of aluminum alloy wheels.

[0003] After die-casting, machining, and painting, aluminum alloy wheels require weight monitoring. Currently, the common method is manual weighing using electronic scales, comparing the weight to the design weight, and investigating and adjusting for discrepancies. However, manual operation cannot cover every single product. During repetitive manufacturing processes, issues such as mold opening and closing, tool wear during machining, and painting rework often cause products to exceed design weights. This can lead to customer complaints, serious safety accidents, mass recalls, or even fatal accidents. Therefore, inventing an intelligent device to replace manual operation is essential.

[0004] Aluminum alloy wheels are mass-produced products. To improve production efficiency and reduce manufacturing costs, wheel factories currently use automated production lines for processing. Therefore, online automatic weighing equipment is essential. Because wheel processing involves mixed-line production, the online weighing equipment must not only meet the weighing requirements but also correlate the weight with the product model to compare it with design standards and ensure that each product meets the design weight requirements.

[0005] The weight monitoring chamber for aluminum alloy wheels is one of the key indicators in the aluminum alloy wheel manufacturing process. It is an important indicator for evaluating the product's safety, reliability, consistency, and metal utilization rate. Moreover, the transfer of materials on the aluminum alloy wheel production line is automated using roller conveyors. Therefore, it is essential to invent a simple, fast, and fully intelligent device that is compatible with the logistics equipment of the aluminum alloy wheel production line.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The online intelligent weighing device for aluminum alloy wheel hubs according to an embodiment of the present invention is described below with reference to Figures 1 to 3 and in conjunction with the embodiments.

[0027] An online intelligent weighing device for aluminum alloy wheel hubs includes: 1. an inlet logistics roller conveyor; 2. an inlet guide wheel; 3. an inlet stepper motor; 4. an aluminum alloy wheel hub model recognition camera; 5. a recognition station stepper motor; 6. an aluminum alloy wheel hub model recognition confirmation camera; 7. a centering clamping device; 8. a main station stepper motor; 9. an outlet stepper motor; 10. an outlet guide wheel; 11. an outlet logistics roller conveyor; 12. a device housing; 13. a device support beam; 14. an electrical configuration cabinet; 15. a device support column; 16. an aluminum alloy wheel hub; and 17. an aluminum alloy wheel hub weighing device. The inlet logistics roller conveyor 1 and the outlet logistics roller conveyor 2 transport the aluminum alloy wheel hubs 16. The aluminum alloy wheel hub model recognition camera 4 and the aluminum alloy wheel hub model recognition confirmation camera 6 perform dual recognition of the aluminum alloy wheel hubs. The aluminum alloy wheel hub weighing device 12 primarily completes the online weighing of the aluminum alloy wheel hubs.

[0028] The inlet photoelectric sensor 2 and the inlet stepper motor 3 are fixed on the inlet logistics roller conveyor 1. The aluminum alloy wheel hub model recognition camera 4 is fixed on the device housing 12. The centering clamping device 7 is fixed on the device housing 12. The outlet stepper motor 9 and the outlet photoelectric sensor 10 are fixed on the outlet logistics roller conveyor 11. The electrical configuration cabinet 14 is fixed on the device support column 15. The device housing 12 is wrapped around the device support beam 13 and the device support column 15.

[0029] This device can perform online weighing of aluminum alloy wheels with diameters of 5-28 inches and widths of 4-15 inches. It boasts a high level of intelligence and expandable production data storage capabilities. Employing a closed-loop control system including PLC, intelligent robots, stepper motors, and image recognition, it can be networked for remote monitoring and control, integrating the internet with industry.

[0030] By adopting the above technical solution, the process flow of this utility model is as follows:

[0031] The aluminum alloy wheel hub 16 is conveyed to the inlet area through the inlet roller conveyor 1. After the inlet photoelectric sensor 2 detects the aluminum alloy wheel hub 16, it transmits the signal to the PLC controller in the electrical configuration cabinet 14. The PLC controller determines whether the inlet stepper motor 3 should continue to rotate based on whether there is a product at the next station.

[0032] The aluminum alloy wheel hub wheel shape recognition camera 4 takes pictures of the aluminum alloy wheel hub 16 that arrives at the recognition station, compares them with the model in the system, identifies the product model, and transmits the information to the PLC controller in the electrical configuration cabinet 14. The PLC controller stores the relevant information for use as a spatial position guide for the main station.

[0033] After the aluminum alloy wheel hub 16 arrives at the main work station, the centering clamping device 7 clamps the aluminum alloy wheel hub 16 to ensure that the product is in the exact center of the work station. After the clamping device 7 is released.

[0034] The aluminum alloy wheel hub weighing device 17 lifts the aluminum alloy wheel hub 16. The aluminum alloy wheel hub model identification and confirmation camera 6 reconfirms the product model, and the model is confirmed by the PLC controller in the electrical configuration cabinet 14. After confirming that the model is correct, the aluminum alloy wheel hub weighing device 17 is instructed to weigh the wheel hub. After weighing, the aluminum alloy wheel hub weighing device 17 returns the aluminum alloy wheel hub 16 to its original position, and the main station stepper motor 8 operates to transfer the aluminum alloy wheel hub 16 to the discharge port logistics roller conveyor 11.

[0035] The aluminum alloy wheel hub 16 is fed to the discharge area via the discharge roller conveyor 11. After the discharge photoelectric sensor 10 detects the aluminum alloy wheel hub 16, it transmits the signal to the PLC controller in the electrical configuration cabinet 14. The PLC controller determines whether the inlet stepper motor 9 should continue to rotate based on whether there is a product at the next station. This completes one full-process operation.
