As key equipment for interacting with IC cards, the performance of IC card reader / writer detection devices directly affects the application effectiveness and user experience of IC cards.

[0003] In existing technologies, IC card read / write detection devices typically employ simple mechanical structures to implement IC card insertion, positioning, and read / write operations. However, these devices present a number of practical problems. For example, some devices suffer from poor mechanical design, leading to IC card slippage or jamming during transmission, impacting the stability and accuracy of read / write operations. Furthermore, some devices lack intelligent detection and control methods, making it impossible to accurately sense the position and status of IC cards, thus preventing automated and intelligent read / write operations.

A sliding shaft 13 is slidably provided in the blind hole 11 and at the outer end of the compression spring 12. A slide plate 14 is fixedly connected to the outer end side of the sliding shaft 13. The slide plate 14 is slidably provided in the card insertion channel 3. An infrared sensing probe 16 is fixedly provided on the upper part of the rear end of the lower shell 2 through a bracket 15. A slide groove 17 is provided on the upper side of the upper shell 1 and corresponding to the front side of the active roller 6. A lifting baffle 18 is provided inside the slide groove 17 for sliding up and down. A rack 19 is vertically fixed in the middle position of one side of the lifting baffle 18. The rack 19 is connected to a lifting control motor 21 through a gear 20. The lifting control motor 21 is fixedly provided on the upper side of the upper shell 1.

[0028] A slot 22 is provided between the upper rear side of the upper shell 1 and the rear end side of the lower shell 2 , and the infrared sensing probe 16 extends to the upper side of the slot 22 . When the compression spring 12 is not compressed, the infrared sensing probe 16 is located on the upper rear side of the slide 14 .

[0029] Both the active roller 6 and the driven roller 7 include a roller body, and a rubber layer is fixedly provided on the outer side of the roller body.

[0030] The upper shell 1 is connected to the lower shell 2 by a snap-fit ​​connection. Slots 201 are symmetrically provided on both upper sides of the lower shell 2 , and clamping strips 101 are provided on both lower sides of the upper shell 1 . The clamping strips 101 are clamped inside the slots 201 .

[0031] The structure of the upper shell 1 and the lower shell 2:

[0032] The upper housing 1 is precision-machined to ensure a smooth surface, while also possessing the strength and rigidity to support the internal mechanical structure. It is fixed to the upper portion of the lower housing 2. The connection between the two is not limited to simple screw fastening, but also utilizes a snap-fit ​​connection technology. The lower housing 2 is symmetrically provided with slots 201 on both sides of the upper portion, while the upper housing 1 is equipped with corresponding clips 101 on both sides of the lower portion. This design not only simplifies the assembly process but also enhances the overall stability.

[0033] Card insertion channel 3 and head guide housing 4:

[0034] The card insertion channel 3 serves as the primary path for IC cards to enter and exit. A head guide housing 4 is fixedly mounted at its front end. Made of a wear-resistant, smooth material, this housing reduces friction during IC card insertion and serves as a guide. A card slot 5 precisely aligned with the position of the card insertion channel 3 ensures accurate IC card insertion and provides a precise positioning guide.

[0035] Active roller 6 and driven roller 7:

[0036] To further enhance IC card transmission efficiency and stability, a rotating active roller 6 is located at the front end of the upper housing 1, with a driven roller 7 positioned below it. Both rollers are constructed with a high-friction rubber coating. This not only enhances the grip on the IC card but also effectively prevents slippage or jamming during card transfer. The outer end of the active roller 6 is connected to a drive motor 10 via a gearbox 9. This motor provides power, ensuring smooth and continuous rotation of the active roller 6, thereby driving the IC card through the card insertion channel 3.

[0037] Compression spring 12 and slide plate 14:

[0038] Inside the rear end of the lower housing 2, a blind hole 11 is designed, in which a compression spring 12 is installed. The outer end of the compression spring 12 is connected to a sliding shaft 13, which is fixedly connected to a slide plate 14. When the IC card is fully inserted, it pushes the slide plate 14 forward, thereby compressing the spring 12. This design not only realizes the automatic positioning of the IC card, but also provides stable support for subsequent read and write operations. In addition, when the drive motor 10 drives the active roller 6 to flip, the compression spring 12 gives the card a rebound force through the slide plate 14, so that the card can smoothly reverse and enter between the active roller 6 and the driven roller 7, ensuring that the card can be smoothly removed.

[0039] Infrared sensor probe 16 and lifting baffle 18:

[0040] In order to improve the intelligence level of the device, an infrared sensor probe 16 is fixedly installed on the upper rear end of the lower shell 2 through a bracket 15. This probe can accurately sense the position of the slide 14, thereby determining whether the IC card is correctly in place. In addition, a slide 17 is provided on the upper shell 1, and a lifting baffle 18 is installed inside to slide up and down. A rack 19 is vertically fixed in the middle position of one side of the lifting baffle 18, and the rack 19 is connected to the lifting control motor 21 through a gear 20. When the infrared sensor probe 16 detects that the IC card is in place, the lifting control motor 21 starts and drives the lifting baffle 18 down through the gear transmission, creating a closed and safe environment for the reading and writing operations of the IC card.

[0041] In summary, this IC card reading and writing detection device realizes efficient, accurate and safe reading and writing operations of IC cards through a series of precisely designed mechanical structures and intelligent sensors, providing users with an excellent user experience.
