Description

Technical Field

[0001] This utility model relates to the technical field of code rate detection devices, specifically a code reader code rate detection device. Background Technology

[0002] Barcode reader read rate testing is a crucial step in evaluating their reliability and is of great significance in fields such as industrial production and logistics management. This testing measures the accuracy with which a barcode reader reads a certain number of codes, providing important data for the selection, optimization, and application of barcode readers. However, existing barcode reader read rate testing devices have many shortcomings and are unable to meet the diverse needs of practical applications. Currently, most testing devices have a narrow range of applications, only capable of testing specific models or types of barcode readers. They have poor compatibility with barcode readers of different brands and specifications, which to some extent limits testing efficiency and increases testing costs. To address this issue, some devices compatible with various barcode readers have emerged. These devices typically display encoded patterns on a screen, requiring users to change the pattern for each reader. However, this detection method has significant drawbacks, severely impacting the reliability and efficiency of the detection results. First, the coded pattern displayed on the screen is a virtual image, fundamentally different from the physical code read by the barcode reader in actual applications. Physical characteristics of the physical code, such as printing defects, reflections, and wrinkles, are difficult to accurately simulate in the virtual image on the screen. Therefore, the read rate obtained under these conditions differs significantly from the results obtained using physical objects, and cannot truly reflect the barcode reader's performance in a real-world working environment. Secondly, different types of barcode readers exhibit significant differences in reading speed, especially some industrial control barcode readers, which have extremely high reading speeds in actual use to meet the demands of high-speed production lines. However, the detection method using a display screen to show the encoded pattern is limited by the inherent limitations of screen refresh rates and cannot keep up with the reading pace of high-speed barcode readers. Furthermore, creating encoded pattern videos specifically for high-speed barcode readers is extremely difficult; it's not simply a matter of playing a fixed image with transitions. It requires incorporating the movement of the encoded pattern, necessitating not only precise design of the encoded content but also coordination of the continuity and stability of pattern transitions, further contributing to low detection efficiency. In addition, due to the combined effects of the above factors, the detected reading rate data deviates significantly from the actual situation, making reliability difficult to guarantee and failing to provide effective support for barcode reader performance evaluation.

[0026] Working Principle: The device uses a double-layered horizontal rigid structural support 1 as its basic frame, providing stable support for the entire detection system. The rotating disk 2 is rotatably connected to the structural support 1 via a rotating shaft 6 and bearings. The servo motor 7, fixed inside the structural support 1, is coaxially fixed to the rotating shaft 6. This design is the core power source for achieving dynamic detection. The servo motor 7 can not only accurately adapt to the reading speed of different barcode readers through its speed adjustment function, meeting the diverse detection needs from ordinary barcode readers to high-speed industrial control barcode readers, but also accurately count and record the number of rotations. Combined with the number of slots 3 on the rotating disk 2 where the coded cards are placed, the total number of scans can be quickly calculated, providing accurate data support for the calculation of the reading rate.

[0027] During the testing preparation phase, staff print the corresponding coding pattern on a card according to the type of barcode reader to be tested. The card is then inserted into the coding card placement groove 3 on the horizontal side of the rotating disk 2. The testing window 8 on the outside of the coding card placement groove 3 ensures that the coding pattern on the card is fully exposed for easy reader recognition. This design supports both single-code and multi-code testing; simply changing the coding card is sufficient, making the operation simple and efficient.

[0028] The barcode reader is secured using a movable barcode reader clamp 4 and a universal clamp accessory 5 to accommodate different models and structures of barcode readers. For conventional industrial control barcode readers such as flange-type and four-corner screw-type readers, multiple equidistant grooves 11 on the vertical plate 10 of the barcode reader clamp 4 can be used with bolts and washers to securely fix them. For barcode readers with special structures such as irregular shapes or handles, the universal clamp accessory 5, which is detachably fixed to the barcode reader clamp 4, plays a crucial role. The elastic telescopic clamp 15 located below the upper L-shaped part 12 of the universal clamp accessory 5 consists of a clamp 17, an anti-slip plate 19, a telescopic rod 18, and a spring 20. The two ends of the spring 20 abut against the clamp 17 and the upper L-shaped part 12 respectively and are placed in the corresponding spring grooves 21 to prevent loosening and slippage. Under the elastic force of the spring 20, the elastic telescopic clamp 15 can adaptively adjust the clamping force. Together with the lower L piece 13 and the foam sponge layer 16 on the elastic telescopic clamp 15 (which can be slightly deformed according to the shape of the barcode reader), it can achieve stable clamping of all common barcode readers in the existing technical field.

[0029] During the testing process, the servo motor 7 drives the rotating disk 2 to rotate, causing the coded cards placed in the curved groove 3 to move synchronously, simulating the dynamic code reading scenario in actual applications. The code reader is fixed to the horizontal side of the rotating disk 2 by the code reader clamp 4, and its lens is aimed at the detection window 8 of the coded card placement groove 3. As the rotating disk 2 rotates, it continuously reads different coded patterns. Because physical cards are used for testing, and the rotation speed can be precisely adjusted by the servo motor 7, it can not only realistically reproduce the code reading environment of the code reader in actual work, but also meet the testing requirements of high-speed industrial control code readers. Finally, by comparing the reading results of the code reader with the total number of scans, the accurate code reading rate is calculated, ensuring the reliability of the testing effect and the efficiency of the testing operation.
