Description

Technical Field

[0001] The present invention relates to the technical field of circuit board production, and in particular to a multi-channel flying inspection machine and a circuit board inspection method. Background Art

[0002] After the production of circuit board products is completed, they need to be packaged before being shipped to customers. Before packaging the circuit board products, they need to be inspected to check whether the circuit board products have defects, bad QR codes, and other abnormalities to avoid bad products from being packaged and shipped to customers. In traditional technology, the circuit board products loaded on the pallet are usually transferred to the inspection station manually, and the circuit board products in the pallet are photographed and inspected by using multiple sets of cameras to take pictures of the whole tray. After the inspection, the pallets that have passed the inspection are stacked and placed manually, and the labels are manually packaged. However, a variety of products with laser QR codes have been added to the circuit board products currently produced. The traditional method of taking pictures of the whole tray with multiple sets of cameras cannot effectively read the laser QR codes due to the small size and reflectiveness of the product laser codes, resulting in inaccurate inspection; moreover, the manual loading, stacking and palletizing, and labeling and packaging are inefficient, with high labor costs, and there is a risk of mixed materials and missed inspections for many products. The repetitive manual operation method is also not suitable for the development trend of manufacturing automation. Summary of the invention

[0003] The present invention provides a multi-channel flying inspection machine and a circuit board inspection method, which can solve the technical problems in traditional technologies of manual loading, stacking and labeling, which are low-cost and inefficient, have the risk of mixing materials and missing inspections, and the method of using multiple groups of cameras to take pictures of the entire plate is not suitable for the inspection of circuit board products with laser two-dimensional codes.

[0009] The labeling device includes a plurality of labeling conveying mechanisms arranged side by side at the labeling station, a label printer and a label lifting mechanism arranged below the labeling conveying mechanisms, and a label picking and labeling mechanism arranged above the plurality of labeling conveying mechanisms for transverse movement.

[0010] The beneficial effects brought about by the technical solution provided by the present invention include:

[0011] Through multiple loading devices, pallets can be loaded from multiple positions at the same time, and multiple pallets can be simultaneously conveyed to the tray detection conveying components of multiple flying detection devices for detection; moreover, the multi-camera flying detection component of each flying detection device can reciprocate along its tray detection conveying component, and can detect the circuit board products in the trays on the tray detection conveying component one by one, and can also effectively detect the circuit board products with laser two-dimensional codes; moreover, the pallets inspected by the multiple flying detection devices can be respectively conveyed to the tray cache conveying components of the multiple tray cache stacking devices, and the pallets that fail the inspection can be automatically closed and buffered by the defective product buffer component at the entrance end of the tray cache conveying component. The trays that have passed the inspection can be automatically collected and stacked by the qualified product stacking component at the outlet end of the tray buffer conveying component, and the cover plate can be automatically taken out and covered on the stacked multiple pallets that have passed the inspection by the cover plate transfer and covering component; then, the stacked multiple pallets that have passed the inspection can be respectively conveyed to the multiple labeling conveying mechanisms of the labeling device by the tray buffer conveying component of the tray stacking device, the corresponding labels can be printed by the label printer, and the printed labels can be lifted onto the labeling conveying mechanism by the label lifting mechanism, and then the label picking and labeling mechanism can grab the labels from the label lifting mechanism, and move and respectively affix the labels to the multiple pallets that have passed the inspection stacked on the multiple labeling conveying mechanisms.

[0012] In this way, the pallets loaded with circuit board products can be automatically loaded, inspected, stacked and labeled, which can greatly improve the inspection efficiency, reduce manual labor and labor costs, and avoid the risk of mixing materials and missing inspections during manual inspections. In addition, the flying inspection device used can inspect the circuit board products in the pallet one by one, and is suitable for the inspection of circuit board products with laser QR codes, making the inspection accurate and efficient.
