Description

Technical Field

[0001] The present invention is applied to the technical field of FCT detection equipment, and particularly relates to a multi-channel code scanning fool-proof test module and a test method thereof. Background Art

[0002] Poka-yoke is a preventative and corrective behavioral constraint. It employs error-avoiding restrictions, allowing operators to accurately complete correct operations without requiring attention, experience, or expertise. Broadly speaking, poka-yoke is about designing a device to minimize the chance of error. Avoiding work errors ultimately ensures the job is done right the first time. From a user perspective, poka-yoke design is designed from the perspective of non-professional, inexperienced users, guiding them through correct operations. Industrial automation testing is no exception; before testing a product, the serial number is typically scanned and then written to internal memory for traceability.

[0003] However, in traditional solutions, only the serial number of a single product is scanned. In multi-channel testing, due to the operator's inattention or lack of skill, the serial number of the product to be tested and the actual test channel often overlap.

[0004] Therefore, it is necessary to provide a multi-channel code scanning and fool-proof test module and its testing method, which uses the scanning of QR codes to identify the slot identification number, and uses the multi-barcode scanning function of the scanner to simultaneously identify the slot identification number and the serial number of the tested board, thereby realizing code scanning and fool-proofing, and effectively eliminating the problem of cross-serial number of the tested board caused by code scanning. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a multi-channel code scanning and fool-proof test module and a test method thereof. The slot identification number is identified by scanning a QR code, and the multi-barcode scanning function of a scanner is used to synchronously identify the slot identification number and the serial number of the tested board, thereby realizing code scanning and fool-proofing, and effectively eliminating the problem of crossed serial numbers of the tested boards caused by code scanning.

[0006] The technical solution adopted by the present invention is: the present invention includes a host computer, a scanning gun and a tested board, the host computer parses the scanning information fed back by the scanning gun, the tested board is provided with a plurality of products, and the tested board is also provided with a serial number QR code and a slot identification number QR code corresponding to each group of products. As can be seen from the above scheme, the scanner synchronously scans the serial number QR code and the slot identification number QR code, uploads them to the host computer for analysis, and the test software first identifies whether the slot identification number is correct. Only when the slot identification number is correct can the test proceed. Since the slot identification number defined for each channel is unique, the problem of serial number identification and storage channel intersection is avoided. This application uses the method of scanning QR codes to identify slot identification numbers, and uses the multi-barcode scanning function of the scanner to synchronously identify slot identification numbers and serial numbers to achieve code scanning foolproofing. It uses the original module of the equipment and does not increase hardware costs. After introducing this foolproofing test step, the problem of serial number intersection caused by code scanning basically does not occur.

[0007] A preferred solution is that the serial number QR code and the slot identification number QR code are sequentially pasted on the upper surface of the tested board, the pasting position of the serial number QR code and the pasting position of the slot identification number QR code are on the same vertical line, and the distance between the serial number QR code and the slot identification number QR code is within 10 mm.

[0008] A preferred embodiment is that the testing method comprises the following steps: Step A1: The scanner scans the serial number QR code and the slot identification number QR code; Step A2: the scanner feeds back the data to the host computer for analysis; Step A3: The host computer determines whether the slot identification number is correct; Step A4: The host computer determines whether the serial number is correct; Step A5: Report the number of channels that have been scanned; Step A6: Determine whether it is the last channel; Step A7: Start product function testing.

[0009] A preferred solution is that, taking 4 channels as an example, the method for making the slot identification number QR code includes the following steps: Step B1: define the slot identification number as a specific string, that is, a combination of letters and numbers. Channel numbers 1-4 are defined as ABCD0001, ABCD0002, ABCD0003, and ABCD0004 respectively. Step B2: Visit the official QR code generator website. Enter the channel number defined in step B1 in the input box, select 480 as the size, and click Generate QR Code. A QR code will be generated immediately on the right. Click Save QR Code to download it to your local computer. Generate and save QR codes for the four channel numbers in sequence. Step B3: Print the QR code generated in step B2; Step B4: Paste the QR codes printed in step B3 onto the upper surface of the tested board in sequence. BRIEF DESCRIPTION OF THE DRAWINGS
