Description

Technical Field

[0001] This invention relates to the field of barcode scanning, and more specifically to an automated multi-angle barcode scanning device. Background Technology

[0002] In the manufacturing and traceability process of 3C electronic components, products are typically handled and processed in the form of whole-board carriers. Each component has QR codes and digital codes on its front and sides for traceability. Traditional methods rely on manual scanning, which suffers from low efficiency, poor accuracy, and high operational difficulty. Especially when the whole-board carrier carries multiple components, manually scanning each one is not only time-consuming but also prone to missed or incorrect scans due to fatigue, affecting the reliability of the production process and data traceability. In addition, the tiny size of the codes on some small components further increases the difficulty of manual scanning. Although automated scanning systems have emerged in existing technologies, they still suffer from problems such as incomplete angle coverage, unstable scanning efficiency, and low system integration, making it difficult to meet the needs of efficient and accurate automated data collection. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes the following solution to resolve the issues of incomplete angle coverage, unstable scanning efficiency, low system integration, and difficulty in meeting the requirements for efficient and accurate automated data collection in existing automated multi-angle scanning devices.

[0004] Specifically, an automated multi-angle barcode scanning device is provided, characterized in that it includes: The vehicle transfer module is used to import and export whole-plate vehicles into and out of the equipment; The CCD transfer module includes an XYZ three-axis servo motor drive system, which enables the camera to move freely in space; The CCD side-scan angle dual-R module has a parallel rotation axis and an angle rotation axis to realize automatic camera angle adjustment; High-precision industrial cameras and light source systems are used to acquire QR code and digitally encoded images; The control system uses PLC control to coordinate the collaborative work of each module. The data upload module uploads the scanned data to the MES system in real time.

[0005] According to a further optimized embodiment of the present invention, the carrier transfer and positioning mechanism has a 360° rotation function, which can rotate the carrier to any angle under the command of the control system, ensuring that the coded positions of all parts can be covered by the camera.

[0006] According to a further optimized scheme of the present invention, the CCD module adopts a "flying camera" method to complete image acquisition during the movement of the vehicle, which greatly shortens the scanning time.

[0007] According to a further optimized scheme of the present invention, the camera is installed at an angle of 50°, the light source angle can be adjusted between 30° and 45°, the working distance is 90mm, the field of view is 20mm×14mm, and the pixel accuracy reaches 0.01mm / pixel, ensuring clear imaging of tiny QR codes and digital codes.

[0008] According to a further optimized solution of the present invention, the barcode data upload module has data integration, analysis and storage functions, realizes full-process traceability of products and closed-loop data management, and introduces a deep learning model at the image recognition algorithm level to improve the recognition ability of fuzzy, tilted and micro-coded data.

[0009] According to a further optimized scheme of the present invention, by collecting a large number of samples to train the model, it is made to have stronger fault tolerance and adaptability, thereby further reducing the bit error rate and improving system stability.

[0010] According to a further optimized scheme of the present invention, a barcode scanning anomaly alarm and automatic rescanning mechanism are introduced: a barcode scanning anomaly detection module is integrated into the device. When recognition fails or data is incomplete, the system automatically triggers the rescanning mechanism and issues an alarm signal after multiple failures to prompt manual intervention, thereby ensuring the integrity and accuracy of data collection.

[0011] According to a further optimized scheme of the present invention, a multi-camera collaborative scanning system is designed: based on the original technical solution, a multi-camera collaborative working mechanism is added, with each camera responsible for scanning tasks in different areas, such as one camera responsible for front scanning, another responsible for side scanning, and a third responsible for vehicle board code recognition. Through data synchronization and control linkage between cameras, scanning efficiency and accuracy are further improved, making it suitable for higher-speed production needs.

[0012] According to the present invention, at least the following positive effects are achieved: The automated multi-angle scanning device of the present invention can effectively solve the problems of incomplete angle coverage, unstable scanning efficiency, low system integration, and difficulty in meeting the requirements of efficient and accurate automated data collection in the prior art. At the same time, it realizes all-round automatic identification and data uploading of the front and side codes of parts.

[0013] By utilizing the 360° rotation technology of the carrier transfer and positioning mechanism, the product can be scanned from any angle, fully covering the coding area of ​​the part in all directions, achieving the technical effect of identification without blind spots.

[0014] By equipping the camera with automatic adjustment technology for parallel and angular rotation axes, the camera can automatically adjust the shooting angle according to the structure of different parts, which can improve the accuracy of image recognition and achieve the technical effect of stable recognition of tiny codes.

[0015] By using 360° rotation of the carrier and dual-axis automatic adjustment technology of the camera, the system can achieve all-round recognition of the QR codes and digital codes on the front and sides of the parts on the entire carrier.

[0016] By utilizing the CCD module to capture images of the entire vehicle product, the equipment can complete image acquisition while the vehicle is in motion, which can significantly shorten the single scanning cycle and achieve the technical effect of improving overall production efficiency.

[0017] By uploading scanned data to the MES system in real time, the collected data can be instantly integrated into the production management system, enabling full-process traceability and management of product information and achieving closed-loop data control. This technology is suitable for production traceability scenarios involving 3C electronic components. Attached Figure Description

[0024] like Figure 1-3As shown, the automated multi-angle scanning equipment is suitable for scanning entire boards of 3C electronic components. The equipment includes a carrier transfer module 1, a CCD transfer module 2, a CCD side-scanning angle dual-R module 3, a light source system (not shown), a control system (not shown), and a data upload module (not shown). The carrier transfer module 1 is responsible for importing the entire board of components from the production line into the equipment. Its transfer positioning mechanism (not shown) has a 360° rotation function, allowing the carrier to be rotated to any angle under the control system's command, ensuring that the coding positions of all parts are covered by the camera. The CCD transfer module 2 is driven by an XYZ three-axis servo motor drive system 4, which moves the camera freely in space, coordinating with the carrier rotation to achieve individual scanning of all parts on the entire board of components.

[0025] The CCD transfer module 2 includes a high-precision industrial camera (5-megapixel monochrome global camera) (not shown), a macro lens (not shown), and a white bar light source (not shown).

The camera achieves automatic angle adjustment through a parallel rotation axis and an angle rotation axis, adapting to different component structures and improving image recognition stability.

[0026] During the scanning process, after the entire pallet carrier enters the equipment, the CCD transfer module 2 uses a "flying camera" method to complete image acquisition while the carrier is moving, greatly shortening the scanning time. The acquired QR code and digital code data are uploaded to the MES system in real time through the equipment's internal data transmission lines, completing data integration, analysis, and storage, and realizing full-process product traceability.

[0027] The overall control system of the equipment adopts PLC control, and the moving parts are driven by servo motors. The operation process includes: the entire carrier enters the equipment → CCD module takes photos → data is scanned and uploaded to the MES system → the entire carrier is removed from the equipment. The equipment has external dimensions of 900mm×1200mm×1800mm, an operating voltage of 220VAC, and an air pressure of 0.5MP~0.7MP, making it suitable for in-line production line operations.
