Description

Technical Field

[0001] This utility model relates to smart card production equipment, specifically to a smart card hot stamping device. Background Technology

[0002] In the production process of smart cards, relevant information (such as text and patterns) is usually printed on the card surface using hot stamping. Hot stamping is achieved through a hot stamping device, which mainly includes a ribbon conveying mechanism, a card conveying mechanism, and a hot stamping mechanism. The hot stamping mechanism primarily includes a hot stamping head. The ribbon conveying mechanism supplies the ribbon to the hot stamping head, and the card conveying mechanism transports the card to be printed to the area below the hot stamping head. During operation, the card is positioned below the hot stamping head, and the ribbon is located between the card and the hot stamping head. The hot stamping head heats a specific point (the area with the pattern) to melt the ink on the ribbon and transfer it to the card surface, forming the information to be printed.

[0003] Currently, the mainstream card feeding method in the industry is the card-on-card method, which involves placing cards in a track, with cards from the rear pushing the cards in front, and then pushing the cards in front to the hot stamping station. The advantage of this method is its relatively simple structure and easy operation, but it also has the following disadvantages:

[0004] 1. The requirements for the track and the thickness of the cards are quite strict. In order to prevent the cards from overlapping, the height of the track is fixed. It can only be used for cards with the right thickness. It is not suitable for cards with a small or large thickness, and its versatility is poor.

[0005] 2. While each card appears to be of equal length, in reality, the lengths of each card are not entirely consistent and will vary slightly. As the cards are fed forward using a card-to-card method, the distance each card is set to advance is not equal to the length of each card. This will gradually accumulate errors, eventually leading to a significant deviation in the relative position of the cards during transport, thus affecting the hot stamping process.

[0006] 3. Some cards are made of delicate materials (such as precious metals), which may cause wear and tear on both sides of the card when it is pushed in the track, which has a negative impact. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned problems and provide a smart card hot stamping device, which has the advantages of good versatility, high precision, and card protection.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A smart card hot stamping device includes a ribbon conveying mechanism, a card conveying mechanism, and a hot stamping mechanism.

[0010] The card conveying mechanism includes a card rotating platform and a rotation drive mechanism for driving the card rotating platform to rotate. The card rotating platform is provided with at least three hot stamping avoidance notches evenly distributed along the circumference. Each hot stamping avoidance notch is provided with a card slot for placing a card. The card rotating platform rotates to feed the card into the hot stamping station and to send the card out of the hot stamping station.

[0011] In a preferred embodiment of this utility model, a pair of mounting blocks are provided at each hot stamping avoidance notch, and each mounting block is provided with the card slot. Thus, the card to be hot stamped can be transported to the card slot by an upstream card conveying mechanism, then the card rotates with the card slot to complete the hot stamping process, and finally the card is passed down by a downstream card conveying mechanism.

[0012] Furthermore, each hot stamping clearance notch is equipped with a clamping structure for holding the card. This clamping structure includes a clamping block, a clamping spring, and a top plate. The clamping block is slidably mounted on the card rotating platform. One mounting block has a sliding groove communicating with the card slot, and the clamping block is positioned within the sliding groove. The card rotating platform has a spring mounting hole, with one end of the clamping spring positioned in the spring mounting hole and the other end resting against the clamping block. The top plate is fixedly mounted on the card rotating platform and covers the spring mounting hole. The clamping spring causes one end of the clamping block to extend into the card slot to clamp the card. With this structure, when the card is fed into the card slot, the clamping block can adaptively clamp the card according to its size, preventing the card from loosening and ensuring the accuracy of the hot stamping.

[0013] In a preferred embodiment of this utility model, each hot stamping avoidance notch has a positioning post on its inner side for positioning the card. In this way, after the card is placed in the card slot, the inward end of the card rests on the positioning post, thereby completing the positioning.

[0014] Furthermore, the positioning post is vertically embedded in the card rotating platform, resulting in a simple and compact structure.

[0015] In a preferred embodiment of this invention, the rotary drive mechanism includes a rotary drive motor and a transmission shaft, wherein the rotary drive motor is fixedly connected to the card rotating platform via the transmission shaft. With this structure, driven by the rotary drive motor, the card rotating platform can rotate while carrying the cards, thereby simultaneously completing the transfer of multiple cards.

[0016] In a preferred embodiment of this utility model, the hot stamping mechanism includes a support mechanism, which includes a support frame, a support platform, and a lifting drive mechanism for driving the support platform to move up and down. The support platform is located directly below the hot stamping station. The lifting drive mechanism includes a lifting drive cylinder and a lifting transmission assembly. The lifting drive cylinder is fixedly mounted on the support frame, and the lifting transmission assembly is connected between the lifting drive cylinder and the support platform.

[0017] Furthermore, the lifting transmission assembly includes a hinge seat, a hinge component, a transmission plate, and a lifting guide structure. The hinge seat includes a first hinge seat and a second hinge seat. The first hinge seat is fixedly mounted on the telescopic rod of the lifting drive cylinder, and the second hinge seat is fixedly mounted on the support frame.

[0018] The hinge includes a first hinge, a second hinge, and a third hinge. One end of the first hinge is hinged to a first hinge seat, one end of the second hinge is hinged to a second hinge seat, and one end of the third hinge is hinged to a transmission plate. The other ends of the first hinge, the second hinge, and the third hinge are connected to the same hinge axis. Two of each of the second hinge seat, the first hinge, the second hinge, and the third hinge are provided and arranged symmetrically.

[0019] The lifting guide structure includes a lifting guide rod and a lifting guide sleeve. The bottom of the lifting guide rod is fixedly connected to the transmission plate, and the top of the lifting guide rod is fixedly connected to the support platform. The lifting guide sleeve is fixedly installed on the support frame.

[0020] With the above structure, in the non-hot stamping state, the support platform will descend to avoid interference with the card rotation platform. After the card rotation platform rotates the card to be hot stamped to the hot stamping station, it is driven upward by the lifting drive cylinder. The first, second, and third hinges transmit power to the transmission plate, which in turn drives the support platform upward through the transmission plate and the lifting guide rod until the support platform supports the card above (slightly lifting it), thus providing sufficient support for the card to complete the hot stamping work.

[0021] Furthermore, the supporting mechanism also includes a limiting structure, which includes a wedge-shaped limiting block and a manual adjusting screw. The manual adjusting screw is rotatably connected to the supporting frame. The wedge-shaped limiting block includes a first limiting block and a second limiting block. Both the first limiting block and the second limiting block are provided with inclined surfaces. The first limiting block cooperates with the manual adjusting screw through a threaded hole. The first limiting block is set on the upper bottom surface of the supporting frame through a guide rail. The second limiting block is fixedly set on the transmission plate.

[0022] With the above structure, the relative positions of the first and second limiting blocks can be manually fine-tuned to adjust the support height of the support platform to accommodate cards of different thicknesses. Specifically, when it is necessary to adjust the support height downward, turn the manual adjustment screw in the corresponding direction to drive the first limiting block to move horizontally along the guide rail, reducing the horizontal distance between the lowest and highest points of the inclined surface of the first limiting block. When the lifting drive cylinder drives upward, the limiting collision height of the first and second limiting blocks will decrease accordingly, that is, the support height of the support platform will also decrease, thereby completing the height adjustment.

[0023] Furthermore, the support mechanism also includes a pressure sensor for detecting the magnitude of the pressure applied during hot stamping.

[0024] In a preferred embodiment of this utility model, the ribbon conveying mechanism further includes a ribbon peeling mechanism for separating the ribbon from the card after hot stamping. The ribbon peeling mechanism includes a ribbon peeling plate and a ribbon peeling drive cylinder. The ribbon peeling plate is disposed on one side of the hot stamping station. The telescopic rod of the ribbon peeling drive cylinder is directly or indirectly connected to the ribbon peeling plate. The ribbon peeling drive cylinder is used to drive the ribbon peeling plate to press against the back of the ribbon to separate the ribbon from the card.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The smart card hot stamping device of this utility model can rotate cards into and out of the hot stamping station by setting a card rotation platform, without the need for a track with a fixed height, and is suitable for cards of different grades, with good versatility.

[0027] 2. Each card is independently transmitted sequentially via a card rotation platform, without being affected by other cards. Therefore, there is no cumulative error due to card length, resulting in higher accuracy.

[0028] 3. Compared to the card-on-top-moving method, the card is rotated and moved to the hot stamping station via a card rotation platform, which causes less wear and tear on the card.

[0029] 4. The card conveying mechanism of this utility model can be directly applied to existing equipment with minimal modifications, and can be directly connected to existing modules, making it more practical. Attached Figure Description

Finally, the card is passed down by the downstream card conveying mechanism.

[0038] Furthermore, each hot stamping clearance notch 101 is equipped with a clamping structure for clamping the card. This clamping structure includes a clamping block 3, a clamping spring 4, and a top plate 5. The clamping block 3 is slidably mounted on the card rotating platform 1. One of the mounting blocks 2 has a sliding groove 202 that communicates with the card slot 201, and the clamping block 3 is positioned within the sliding groove 202. The card rotating platform 1 has a spring mounting hole, one end of the clamping spring 4 is positioned in the spring mounting hole, and the other end rests against the clamping block 3. The top plate 5 is fixedly mounted on the card rotating platform 1 and covers the spring mounting hole. The clamping spring 4 is used to cause one end of the clamping block 3 to extend into the card slot 201 to clamp the card. With this structure, when the card is fed into the card slot 201, the clamping block 3 can adaptively clamp the card according to its size, preventing the card from loosening and ensuring the accuracy of the hot stamping.

[0039] Combination Figure 1 Each hot stamping avoidance notch 101 has a positioning post 6 on its inner side for positioning the card. In this way, after the card is placed in the card slot 201, the inward end of the card rests on the positioning post 6, thereby completing the positioning.

[0040] Furthermore, the positioning post 6 is vertically embedded on the card rotating platform 1, resulting in a simple and compact structure.

Through this structure, driven by the rotary drive motor 7, the card rotation platform 1 can rotate while carrying the cards, thereby simultaneously completing the transfer of multiple cards.

[0042] Combination Figure 3 and Figure 4 The hot stamping mechanism includes a support mechanism, which includes a support frame 8, a support platform 9, and a lifting drive mechanism for driving the support platform 9 to move up and down. The support platform 9 is located directly below the hot stamping station. The lifting drive mechanism includes a lifting drive cylinder 10 and a lifting transmission assembly. The lifting drive cylinder 10 is fixedly mounted on the support frame 8, and the lifting transmission assembly is connected between the lifting drive cylinder 10 and the support platform 9.

[0043] Furthermore, the lifting transmission assembly includes a hinge seat, a hinge member, a transmission plate 11, and a lifting guide structure. The hinge seat includes a first hinge seat 12 and a second hinge seat 13. The first hinge seat 12 is fixedly mounted on the telescopic rod of the lifting drive cylinder 10, and the second hinge seat 13 is fixedly mounted on the support frame 8.

[0044] With the above structure, in the non-hot stamping state, the support platform 9 will descend to avoid interference with the card rotation platform 1. When the card rotation platform 1 rotates the card to be hot stamped to the hot stamping station, it is driven upward by the lifting drive cylinder 10. The first hinge 14, the second hinge 15 and the third hinge 16 transmit power to the transmission plate 11. Then, the transmission plate 11 and the lifting guide rod 17 drive the support platform 9 to move upward until the support platform 9 supports the card above (slightly lifts it), thereby providing sufficient support for the card to complete the hot stamping work.

[0045] Furthermore, the supporting mechanism also includes a limiting structure, which includes a wedge-shaped limiting block and a manual adjusting screw 19.

The first limiting block 20 is set on the upper bottom surface of the supporting frame 8 through a guide rail. The second limiting block 21 is fixedly set on the transmission plate 11.

[0046] With the above structure, the relative positions of the first limiting block 20 and the second limiting block 21 can be manually fine-tuned to adjust the support height of the support platform 9 to accommodate cards of different thicknesses. Specifically, if the support height needs to be adjusted downwards, the manual adjustment screw 19 is turned in the corresponding direction to drive the first limiting block 20 to move horizontally along the guide rail, reducing the horizontal distance between the lowest point and the highest point of the inclined surface of the first limiting block 20. When the lifting drive cylinder 10 is driven upwards, the limiting collision height of the first limiting block 20 and the second limiting block 21 will decrease accordingly, that is, the support height of the support platform 9 will also decrease, thereby completing the height adjustment.

[0047] Furthermore, the support mechanism also includes a pressure sensor for detecting the magnitude of the pressure applied during hot stamping.

The ribbon peeling mechanism includes a ribbon peeling plate 22 and a ribbon peeling drive cylinder 23. The ribbon peeling plate 22 is disposed on one side of the hot stamping station. The telescopic rod of the ribbon peeling drive cylinder 23 is directly or indirectly connected to the ribbon peeling plate 22. The ribbon peeling drive cylinder 23 is used to drive the ribbon peeling plate 22 to press against the back of the ribbon to separate the ribbon from the card.

[0049] This invention relates to a smart card hot stamping device. By incorporating a card rotating platform, it can rotatably feed cards into and out of the hot stamping station, eliminating the need for a fixed-height track. This makes it suitable for cards of various sizes and offers good versatility. Each card is independently and sequentially transported via the rotating platform, preventing interference from other cards and thus eliminating cumulative errors in card length, resulting in higher precision.
