Description

Technical Field

[0001] The utility model specifically relates to the technical field of double barcode automatic scanning and binding, in particular to a binding device for scanning two barcodes at the same time. Background Art

[0002] Dual barcodes on PCB boards are usually used for product traceability and identification; dual barcodes can help achieve traceability of the product production process and facilitate analysis, control and improvement of quality anomalies; in the PCB design and production process, it is very important to ensure the quality and readability of dual barcodes. This helps improve production efficiency, ensure product quality, and meet customer and regulatory requirements;

[0003] The barcode on the PCB board is the identity proof of the PCB board. When storing, the two barcodes on the PCB board need to be scanned. In the prior art, employees use handheld barcode scanners to scan the two barcodes separately and upload them to MES for binding. It is easy for other products to be scanned during the scanning process, or when scanning NG, manual scanning is not discovered, resulting in cross-binding errors.

[0004] After searching, Chinese patent application number CN201720195732.X discloses a dual-camera barcode scanning device; it includes two camera units, two driving units, a processing unit, a control unit and a decoding unit. The two camera units respectively shoot the object to be scanned with a first focal length to obtain a first image and a second image, and the optical axes of the two camera units are parallel and separated by a fixed first length. The processing unit obtains the first distance of the object to be scanned from the first camera unit according to the first focal length, the first length, and the first position coordinates and the second position coordinates of the image of the object to be scanned in the first image and the second image relative to the center point of the image. The control unit controls the first driving unit to complete the automatic focusing of the first camera unit according to the first distance. The decoding unit performs barcode decoding based on the third image of the object to be scanned obtained by the first camera unit after completing the automatic focusing;

[0005] When the structure in the above patent scans the double barcodes, the scanning range of the two camera units is large, so barcodes at other positions may be scanned simultaneously, which will cause cross-storage of confidence, which will cause abnormal binding. When the camera unit in the above patent is scanning, it cannot effectively read the barcode and cannot effectively prompt the staff. When continuing to scan, it will cause cross-binding of two adjacent PCB boards;

[0006] In view of the above situation, we provide a binding device for scanning two barcodes at the same time. A first scanner and a second scanner are provided in the device. The barcode on the PCB board is scanned respectively by the first scanner and the second scanner. The barcode is scanned by the first scanner by pressing the contact switch. When the first scanner reads the barcode successfully, a delay of 500ms is set because it is necessary to wait for an identification time of the upper computer software. Then the signal is output from the OK port of the first scanner to the ICOM input port of the second scanner, triggering the second scanner to scan; when the first scanner cannot read within a fixed time, a signal is output to the buzzer through the NG port of the first scanner, which triggers the buzzer to alarm and prompt NG. When the second scanner cannot scan the barcode within the specified time, the signal is transmitted to the buzzer through the NG on the second scanner, prompting NG; effectively avoiding cross binding during scanning.
