[0002] In the production process of smart cards, after completing the reading and writing of smart card data, it is necessary to go through the process of double-sided laser printing of surface markings. Double-sided marking requires the smart card to be flipped over. This structure requires accurate flipping positioning, high efficiency, and easy maintenance and replacement of parts.

[0003] The existing flipping device mainly includes a card conveying assembly and a card flipping assembly, wherein the card conveying assembly includes a conveying roller, and in order not to block the card, the conveying roller will be arranged upstream and downstream of the printing station; the card flipping assembly includes a card flipping seat and a flipping drive structure, and the card flipping seat is provided with a conveying card slot; in order to prevent the card from moving during printing, the prior art sets a damping structure in the conveying card slot to flexibly position the card.

[0004] The existing flipping device has the following shortcomings:

[0005] When an error occurs on a card, the card can only be forcibly removed from the card flipping seat, which will cause irreversible damage to the card and make it impossible to recycle it. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a smart card flipping device, which can not only fix and limit the card, but also facilitate the removal of the card without causing damage to the card.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A smart card flipping device comprises a card conveying mechanism and a card flipping mechanism;

[0009] The card flipping mechanism comprises a flipping seat and a flipping driving mechanism; the flipping seat is a split structure, which comprises two split seats; both split seats are provided with a card conveying slot;

[0010] The flipping drive mechanism includes a flipping drive motor, a synchronous rotating shaft and a flipping transmission assembly; the flipping transmission assembly is provided with two groups and both include a flipping synchronous transmission structure, a fixed seat and a first transmission shaft; the synchronous rotating shaft is connected to two groups of flipping transmission assemblies; the flipping synchronous transmission structure of one group of flipping transmission assemblies is connected between one end of the synchronous rotating shaft and one end of the corresponding first transmission shaft, and the first transmission shaft of one group of flipping transmission assemblies is rotatably connected to the corresponding fixed seat, and the other end of the first transmission shaft is fixedly connected to the corresponding split seat; the other group of flipping transmission assemblies also includes a second transmission shaft, a circumferential transmission sleeve and an adaptive compression spring; the flipping synchronous transmission structure of another group of flipping transmission assemblies is connected between the other end of the synchronous rotating shaft and one end of the second transmission shaft; the second transmission shaft is rotatably connected to the corresponding fixed seat; the first transmission shaft of another group of flipping transmission assemblies can slidably pass through the second transmission shaft, one end of the first transmission shaft is fixedly connected to the circumferential transmission sleeve, and the other end of the first transmission shaft is fixedly connected to the corresponding split seat;

[0012] The adaptive compression spring is sleeved on the first transmission shaft, one end of the adaptive compression spring is pressed against the end of the second transmission shaft away from the circumferential transmission sleeve, and the other end of the adaptive compression spring is pressed against the first transmission shaft.

[0013] The working principle of the above-mentioned smart card flipping device is as follows:

[0014] During operation, the card is conveyed to the flip seat through the card conveying mechanism, and the two side ends of the card are located in the two conveying card slots; wherein, since the two ends of the adaptive clamping spring are pressed against the first transmission shaft and the second transmission shaft, the adaptive clamping spring can provide an adaptive clamping force for the corresponding split seat, so that it can load cards of different sizes and clamp and position the cards to prevent the cards from shifting.

[0015] When the card needs to be flipped, the flip drive motor drives the synchronous shaft to rotate, and the synchronous shaft drives the flip synchronous transmission structure of the two sets of flip transmission components to perform synchronous transmission, so that the first transmission shafts of the two sets drive the two split seats to complete the synchronous flip operation. The specific operation is: the flip synchronous transmission structure of one set of flip transmission components drives the corresponding first transmission shaft to rotate, directly driving the corresponding split seat to flip; at the same time, the flip synchronous transmission structure of one set of flip transmission components drives the corresponding second transmission shaft to rotate, and the second transmission shaft then transmits power to the first transmission shaft through the circumferential transmission sleeve, thereby driving the corresponding split seat to flip.

[0016] When an error occurs in the card, the circular transmission sleeve can be pulled outward so that the second circumferential limit portion on the circular transmission sleeve will withdraw from between two adjacent first circumferential limit portions; at the same time, the circumferential transmission sleeve drives the first transmission shaft to move outward, and the adaptive clamping spring is compressed and deformed at this time, so that the corresponding split seat can move away from the other split seat, exposing the card for taking out the card without causing damage to the card, which is very clever.

[0017] A preferred embodiment of the present invention, wherein the flip synchronous transmission structure is a synchronous belt transmission structure, which includes a synchronous belt, a synchronous wheel and a tensioning wheel; the tensioning wheel is rotatably connected to a tensioning mounting plate; and the tensioning mounting plate is fixedly connected to the fixing seat.

[0018] A preferred embodiment of the present invention is that the card conveying mechanism is provided with two groups and is respectively located upstream and downstream of the flip seat, each group of card conveying mechanism includes a conveying rail, a conveying roller and a conveying drive mechanism; the conveying rail is provided with a conveying card slot; the conveying roller is provided with at least one group and each group of conveying rollers includes two conveying rollers arranged up and down; the conveying drive mechanism is connected to the conveying roller power.

[0019] Furthermore, the conveying drive mechanism includes a conveying drive motor and a conveying transmission assembly; the conveying transmission assembly includes a conveying transmission shaft, a synchronous belt structure and a gear structure, and there are multiple conveying transmission shafts, one end of the conveying transmission shaft is connected to the conveying roller, and the other end of the conveying transmission shaft is connected to the gear structure; the two conveying transmission shafts connected to the same group of conveying rollers are connected through the gear structure; the synchronous belt structure is connected between the conveying drive motor and the conveying transmission shaft.

[0020] Furthermore, the conveying drive mechanisms of the two sets of card conveying mechanisms share a conveying drive motor.

[0021] Furthermore, the card conveying rail comprises a fixed rail and a movable rail, and the movable rail is arranged on the frame through a transverse guide structure; the moving direction of the transverse guide structure is perpendicular to the card conveying direction.

[0022] Furthermore, the transverse guide structure includes a transverse guide rail and a transverse slider, the transverse guide rail is fixedly arranged on the frame, and the transverse slider is fixedly connected to the movable rail.

[0023] Furthermore, the smart card flipping device also includes a card-pick mechanism, which includes a card-pick swing arm and a card-pick driving motor; the rotation center of the card-pick swing arm is vertically arranged, one end of the card-pick swing arm is directly or indirectly connected to the output shaft of the card-pick driving motor, and the other end of the card-pick swing arm is provided with a card-pick portion; the top of the movable rail is provided with an avoidance groove for avoiding the swinging of the card-pick portion. Through the above structure, under the drive of the card-pick driving motor, the card-pick swing arm can drive the card-pick portion to approach the card conveying channel, so that the card coming from the upstream conveying roller is pushed into the flip seat or the card is pushed from the flip seat to the downstream conveying roller, ensuring that the card successfully completes the printing work.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The smart card flipping device of the present invention adopts a flipping seat with a split structure. An adaptive clamping spring can provide an adaptive clamping force for one of the split seats, so that it can not only load cards of different sizes, but also clamp and position the cards to prevent the cards from shifting.

[0026] 2. By setting up a second transmission shaft and a circumferential transmission sleeve, when flipping, the circumferential transmission sleeve transmits the second transmission shaft to the first transmission shaft, thereby ensuring normal flipping work; when an error occurs in the card, just pull the circumferential transmission sleeve outward to make the corresponding split seat away from the other split seat, exposing the card so that the card can be taken out without causing damage to the card, which is very clever.
