Description

Technical Field

[0001] The utility model relates to a smart card production device, in particular to a smart card embossing device. Background Art

[0002] During the production of smart cards, a smart card embossing device is used to print characters on the surface of the card. The device primarily comprises a code disk and a die striking mechanism. The code disk comprises an upper code disk, a lower code disk, and a code disk drive mechanism. The upper and lower code disks are horizontally arranged circular discs with dies arranged opposite each other in the circumferential direction. During operation, two die striking mechanisms simultaneously strike a pair of dies in the upper and lower code disks, striking the card located between the two dies and striking the characters in the dies onto the card. For example, the invention application with publication number CN106142850A discloses a device for controlling the depth of embossing and concave printing on smart cards.

[0003] Furthermore, to improve the quality of embossing, a certain holding time (dwelling time) is required after striking. Furthermore, due to the asymmetric structure of embossing, different holding times are required for the concave and convex dies to achieve high-quality embossing. Existing embossing devices use a single power mechanism to drive the hammers of the concave and convex dies for synchronous striking. While this simplifies the structure, the hammers of the concave and convex dies move synchronously and cannot be controlled individually. This also prevents the ability to reserve different holding times as needed, leaving the embossing quality in need of improvement. Utility Model Content
