Embodiment 1
[0028] Such as Figure 1-3 As shown, the present invention discloses a device for detecting airbag bags, which includes a detection frame 1, a product turnover vehicle 2 to be inspected, a good product turnover vehicle 3, a defective product turnover vehicle 4, a transparent flat panel detection component, and a fixed bracket 7. Detection camera 8, server (not shown), slide rail assembly and vacuum suction cup assembly, product turnover vehicle 2 to be inspected, good product turnover vehicle 3 and defective product turnover vehicle 4 are placed in the detection frame 1 in sequence, and The product turnover car 2 is separated from the good product turnover car 3 and the defective product turnover car 4 through the transparent flat plate detection component. The fixed bracket 7 is installed above the transparent flat plate detection component, and a number of detection cameras 8 are installed and fixed. The detection camera 8 passes through the The signal line is connected to t...

[0038] Experimental purpose and method:
[0039] When this method quickly detects airbag bags, it is necessary to prepare CAD drawings for standard comparisons in advance for different products, and set size standards at corresponding positions. After integrating the images collected by the detection camera 8, they are compared with standard CAD to check whether If there is any inconsistency, measure the corresponding size in the image. If it meets the standard, it is judged as OK, and if it does not meet the standard, it is judged as NG. By measuring several types of sizes in the airbag bag, calculate % GR&R and NDC to verify the repeatability and accuracy of the inspection. reproducible results.

[0043] As shown in the above table, the data in the table selects several types of air bag inspections for the analysis and test of the measurement ...
Embodiment 3
[0045] Experimental purpose and method:
[0046]The device can automatically inspect and classify the air bags to be inspected. The traditional method is manual measurement through template comparison and steel ruler. Due to different personnel measurement, there are large errors and disputes. Using the method of the present application, the inspection time of each airbag can be completed in only 5 seconds, and the measurement error is less than or equal to 1mm. In order to fully verify the accuracy of this application compared with manual inspection, this embodiment selects several SC sizes in the air bag for the same air bag to perform manual and automatic detection processing by the device of this application.

[0050] Note: The unit in Table 2 is millimeter (mm).
[0051] As shown in the above table, the selected SC size tests all meet the...
