However, the two sides of the transmission device located on the two sides of the transmission belt are not provided with a limiting structure, and when the substrate is conveyed on the transmission belt, the two sides of the substrate are limited, so that the substrate is easily moved to the two sides of the transmission device when it is conveyed on the transmission belt, causing the position of the substrate to deviate, affecting the scanning of the camera. SUMMARY

[0009] Preferably, a controller is installed below the top of the mounting column.

[0010] This utility model provides an automatic barcode scanning device, which has the following beneficial effects:

[0011] 1. This automatic barcode scanning device, equipped with a track, a first ball screw, and a moving block, allows adjustment of the positions of two limiting plates according to the size of the substrate to be scanned. By rotating the worm gear, the worm wheel drives the first ball screw to rotate, which in turn drives the moving block to move the limiting plates. The position of the limiting plates is adjusted by observing the scale on the visible ruler pointed to by the moving block. Thus, the two limiting plates limit the two sides of the substrate moving on the conveyor mechanism, preventing the substrate from shifting to the sides of the conveyor during movement and affecting the scanning of the substrate.

[0012] 2. This automatic barcode scanning device, equipped with a moving block, a second servo motor, and a first electric telescopic rod, automatically removes problematic substrates from the transport mechanism when they cannot be scanned. The telescopic end of the first electric telescopic rod pushes the second electric telescopic rod and the substrate vacuum suction cup to move above the substrate. Then, the telescopic end of the second electric telescopic rod pushes the substrate vacuum suction cup downwards, bringing its bottom into contact with the substrate surface. The substrate vacuum suction cup then activates, holding the substrate in place. The telescopic end of the second electric telescopic rod then moves the substrate vacuum suction cup and the substrate upwards. The telescopic end of the first electric telescopic rod then moves the second electric telescopic rod, the substrate vacuum suction cup, and the substrate back to their original positions. The output of the second servo motor rotates the first electric telescopic rod, the second electric telescopic rod, and the substrate vacuum suction cup above the placement stage. The telescopic end of the second electric telescopic rod then pushes the substrate vacuum suction cup and the substrate downwards. Finally, the substrate vacuum suction cup closes, allowing the substrate to fall onto the top of the placement stage. This automatically removes problematic substrates from the transport mechanism and places them on the top of the placement stage for further processing. Attached Figure Description
