Abstract
Description
Technical Field
[0001] This utility model belongs to the field of EAS label inspection technology, and specifically relates to an online inspection device for EAS label die-cutting. Background Technology
[0002] EAS tags typically refer to tags used in Electronic Article Surveillance (EIS) systems. They must meet dual standards in terms of physical structure and electronic parameters (such as resonant frequency and quality factor) to ensure the effectiveness of the anti-theft function. Die-cutting is a common process in the printing and manufacturing industries, used to cut materials into specific shapes. During production, some EAS tags may be defective. Traditional processes rely on manual inspection, which suffers from low efficiency and insufficient quality. Therefore, modern production utilizes online inspection devices to achieve efficient and high-quality inspection of defective tags. After detecting defective products, common EAS tag die-cutting online inspection devices typically use an internal cylinder structure to drive a marking component to mark the defective EAS tags. However, the contact between the cylinder structure and the marking component and the EAS tag can create resistance, affecting the accurate guidance of EAS tags at different workstations.
[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
