[0001] This utility model relates to the field of shielding cover identification code scanning technology, and in particular to a shielding cover identification code scanning device. Background Technology

[0002] In the field of electronic component manufacturing, shielding covers, as key components for preventing electromagnetic interference, typically require markings on their surfaces with identification information such as model number, batch number, and production date to enable production traceability, quality control, and logistics management. This information is often generated as QR codes or barcodes through laser engraving or inkjet printing, and the accuracy of these markings directly impacts production line efficiency and product compliance.

[0003] However, since shielding covers are mostly made of metal, their surfaces have high reflectivity. Traditional vision devices are susceptible to uneven lighting and glare interference, leading to poor image acquisition quality, which in turn affects the accuracy of code reading and makes stable recognition impossible. Utility Model Content

[0004] Based on this, the present invention provides a shielding cover identification code scanning device, which has a simple structure and is easy to use. By adjusting the scanning angle with a rotary cylinder and fine-tuning the focus with a slide cylinder, it effectively overcomes reflection interference, improves the recognition accuracy, and achieves efficient and stable scanning of shielding cover identification codes, ensuring the efficiency of production traceability and quality control.

[0006] The aforementioned shielding cover identification code scanning device has a simple structure and is easy to use. By adjusting the scanning angle with a rotary cylinder and fine-tuning the focus with a slide cylinder, it effectively overcomes reflection interference, improves recognition accuracy, and achieves efficient and stable scanning of shielding cover identification codes, ensuring the efficiency of production traceability and quality control.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 6 The shield identification code scanning device according to one embodiment of the present invention includes a feeding component 10 and a scanning component 20 installed at one end of the feeding component 10.

[0018] The feeding assembly 10 includes a feeding conveyor belt 11, an operating table 12 located at one end of the feeding conveyor belt 11, a three-axis linear module 13 mounted on the operating table 12, a pick-up hand 14 connected to the end of the three-axis linear module 13, and a temporary storage platform 15 mounted in the middle of the operating table 12. The feeding conveyor belt 11 is used to supply the shielding cover 30 to be scanned. The three-axis linear module 13 is used to drive the pick-up hand 14 to move precisely along the XYZ axes, thereby stably picking up the shielding cover 30 from the feeding conveyor belt 11 and temporarily placing it on the temporary storage platform 15 for buffering. Subsequently, the shielding cover 30 is transferred from the temporary storage platform 15 to the scanning assembly 20 for identification code scanning. This effectively avoids excessive accumulation of the shielding cover 30 to be scanned at the scanning assembly 20, prevents the scanning assembly 20 from becoming congested, and ensures the continuity of the scanning process.

[0019] like Figure 3 and Figure 4As shown, the material handling hand 14 includes a fixed frame 141 connected to the end of the three-axis linear module 13, positioning cameras 142 installed at opposite ends of the fixed frame 141, and multiple suction nozzles 143 installed between the two positioning cameras 142. The two positioning cameras 142 can acquire real-time position images of the shielding cover 30 to be picked up and feed them back to the control system, achieving precise visual positioning of the shielding cover 30 and providing accurate suction coordinates for the suction nozzles 143, ensuring that the suction nozzles 143 can accurately and stably pick up the shielding cover 30.

[0020] The scanning assembly 20 includes a feeding conveyor belt 21 located at one end of the operating table 12 away from the feeding conveyor belt 11, a rotary cylinder 22 fixedly installed on one side of the inlet end of the feeding conveyor belt 21, a slide cylinder 23 connected to the rotor of the rotary cylinder 22, and a scanning camera 24 connected to the slide of the slide cylinder 23; the lens of the scanning camera 24 faces the working surface of the feeding conveyor belt 21.

[0021] Specifically, such as Figure 5 As shown, the rotation axis of the rotary cylinder 22 is parallel to the working surface of the unloading conveyor belt 21; the axis of the scanning camera 24 is aligned with the movement direction of the slide cylinder 23, while the movement direction of the slide cylinder 23 is perpendicular to the rotation axis of the rotary cylinder 22. In actual scanning operations, the control system can control the rotary cylinder 22 to rotate at a certain angle based on the reflective characteristics of the shielding cover 30, thereby adjusting the shooting angle of the scanning camera 24. This effectively avoids interference from the high reflectivity of the metal shielding cover surface. Simultaneously, the slide cylinder 23 can drive the scanning camera 24 to fine-tune its focus, ensuring that the scanning camera 24 can clearly acquire the identification code image, significantly improving the reading accuracy of the identification code and achieving a stable and reliable identification effect.

[0022] Furthermore, the scanning assembly 20 also includes limiting plates 25 installed on opposite sides of the working surface of the unloading conveyor belt 21, non-conforming product unloading pipes 26 respectively installed on the outside of each limiting plate 25, and a push-pull plate 27 movably installed between the two non-conforming product unloading pipes 26; the push-pull plate 27 is fixedly connected to the unloading conveyor belt 21 via a push-pull cylinder 28. The moving direction of the push-pull plate 27 is perpendicular to the conveying direction of the unloading conveyor belt 21. The push-pull cylinder 28 drives the push-pull plate 27 to push the non-conforming shielding cover 30 from the working surface of the unloading conveyor belt 21 to the non-conforming product unloading pipe 26, causing it to fall along the non-conforming product unloading pipe 26 to a preset collection container for centralized collection, ensuring that only qualified products are conveyed at the outlet end of the unloading conveyor belt 21, thus achieving integrated scanning and screening operations.

[0023] Specifically, the limiting plate 25 has a notch 250 in the middle, which corresponds one-to-one with the non-conforming product discharge pipe 26; the bottom end of the push-pull plate 27 has a protrusion 270, which is used to abut and push the shield 30, and the protrusion 270 is used to pass through the notch 250 to ensure that the non-conforming product shield 30 can be stably pushed into the non-conforming product discharge pipe 26 along the notch 250, thus ensuring the reliability of the screening action.

[0024] The aforementioned shielding cover identification code scanning device has a simple structure and is easy to use. By adjusting the scanning angle with a rotary cylinder 22 and fine-tuning the focus with a slide cylinder 23, it effectively overcomes reflection interference, improves the recognition accuracy, and achieves efficient and stable scanning of shielding cover identification codes, ensuring the efficiency of production traceability and quality control.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
