Description

Technical Field

[0001] This utility model relates to the field of smart label technology, specifically to a smart label die-cutting positioning structure with a dual positioning mechanism. Background Technology

[0002] In the production process of smart labels, the die-cutting positioning structure is the core equipment for achieving accurate label positioning and efficient cutting. The existing die-cutting positioning structure has significant shortcomings, which limits the quality and cost-effectiveness of smart label production. First, positioning mechanisms often rely too heavily on mechanical limits or manual adjustments, leading to inaccurate cutting positions. This is especially true when processing RFID tags with metal antennas, where the precise position of the antenna cannot be reliably detected, easily causing cutting offsets or tag damage. This increases scrap rates and material waste. Second, existing systems lack adaptability, and moving components cannot be quickly adjusted to adapt to different tag sizes, requiring frequent shutdowns and resetting, which reduces production efficiency. To address these issues, we propose an intelligent tag die-cutting positioning structure with a dual positioning mechanism. Utility Model Content

[0015] The working principle of the intelligent label die-cutting positioning structure with dual positioning mechanism provided by this utility model is as follows: First, the RFID label roll is placed on the belt conveyor 3.

During the movement, the label roll passes through the limiting frame 61 and guide wheel 62 of the limiting component 6. These components limit the movement range of the label roll and ensure its smooth operation. At the same time, the motor 74 of the moving component 7 drives the bidirectional screw 73 to rotate, so that the first mounting frame 72 drives the limiting frame 61 to move synchronously under the constraint of the limiting rod 75, thereby adjusting the spacing between the guide wheels 62 to accommodate label rolls of different sizes. When the label roll is transported above the fixed block 41, the metal sensor 42 of the sensing component 4 detects the metal on the intelligent label. The antenna is positioned and transmits the signal to the PLC controller; the illumination lamp 82 of the imaging component 8 provides sufficient light, and the camera 83 captures the tag area located above the fixing block 41 and sends the image data to the PLC controller to assist in accurate positioning; after positioning, the hydraulic rod 91 of the fixing component 9 drives the clamping frame 92 to descend, and the anti-slip rubber frame 93 clamps the tag roll to prevent it from shifting during the cutting process; subsequently, the electric telescopic rod 52 of the cutting component 5 drives the connecting plate 53 and the cutting frame 54 to descend, and cooperate with the fixing block 41 to perform the die-cutting operation to complete the cutting of the smart tag; the whole process is automated under the coordination of the PLC controller, ensuring efficient transportation, accurate positioning and precise die-cutting of RFID tag rolls of different sizes, reducing scrap rate and improving production efficiency.
