[0043] 9. Qualified products flow into the next workstation through the assembly line.

[0044] The present invention has the following advantages compared with the traditional detection scheme:

[0045] Optimized optical configuration: Improve the optical system to enable it to more accurately detect the appearance defects and dimensions of the product. This may include using cameras with higher resolution, more advanced lighting technologies, or more precise sensors.

[0046] Action splitting: Decompose the detection process into multiple workstations, and each workstation is responsible for a specific detection task. This can improve the specialization and efficiency of detection, while reducing the complexity of a single workstation.

[0047] Function integration: Integrate the functions of dimension detection and appearance detection into the same device, reduce the number of devices, save space, reduce costs, and improve the coherence of the detection process.

[0048] Automation and intelligence: Introduce automation technologies, such as robots or automated conveying systems, to improve the automation level of the detection process. At the same time, use intelligent algorithms to analyze the detection data to improve the accuracy and speed of detection.

[0050] Comprehensive inspection: Ensure that the detection equipment can cover all appearance surfaces of the product, including difficult-to-detect areas, such as titanium surfaces.

[0051] Optimization of production rhythm: Through the above measures, even if the number of detection items is increased, the production rhythm can be reduced by improving the detection efficiency, that is, the number of products produced per unit time.

[0052] Data integration and analysis: Integrate the detection data into a unified system for easy monitoring and analysis, so as to timely discover problems in the production process and make adjustments.

[0053] Quality control: Improve the product quality control level through more comprehensive inspections and reduce the production of defective products.
