Description

Technical Field

[0001] This disclosure relates to the fields of card reader / writer technology and financial technology, specifically to a card reader / writer device, an automated transaction system, and an automated transaction method. Background Technology

[0002] With the development of financial services, ATMs (Automated Teller Machines) have become an important part of banking services, providing users with a convenient way to conduct transactions independently. However, in the traditional use of ATMs, users must correctly insert their bank cards into the card reader. If the card is inserted incorrectly, the reader will fail to read the card, rendering it unusable. In this situation, users often need to reinsert the card, which not only increases transaction time but may also lead to dissatisfaction and confusion among customers, especially elderly customers, negatively impacting their user experience.

[0003] As my country's population ages, the proportion of elderly customers among financial service users continues to rise. This group has higher requirements for the ease of use and user-friendliness of self-service equipment such as ATMs. Therefore, how to optimize the user experience of ATMs through technological innovation and reduce errors caused by improper operation has become an important issue for banks and financial institutions.

[0105] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0106] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0107] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0108] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0109] Embodiments of this disclosure provide a card reader / writer device capable of adjusting the orientation of an internal card 2 so that orientation adjustment and information reading / writing can still be performed even when the card 2 enters the card reader / writer device in the wrong orientation.

[0110] Figure 1 A schematic diagram of a card reader / writer apparatus according to an embodiment of the present disclosure is shown.

[0111] like Figure 1 As shown, the card reader / writer includes a reader / writer mechanism 1, which includes an upper holding mechanism 11 and a lower holding mechanism 12 arranged opposite to each other. At least one of the upper holding mechanism 11 and the lower holding mechanism 12 includes a reader / writer 13, which is configured to perform information reading and writing on a card 2 held between the upper holding mechanism 11 and the lower holding mechanism 12. The reader / writer 13 is also configured to lift the upper holding mechanism 11 away from the lower holding mechanism 12 and rotate the card 2 180 degrees after lifting the card 2 between the upper holding mechanism 11 and the lower holding mechanism 12.

[0112] According to the above configuration, by installing a reader / writer 13 on at least one of the upper holding mechanism 11 and the lower holding mechanism 12, and by installing a drive mechanism 3, the automatic lifting and 180-degree rotation of the card 2 held between the upper holding mechanism 11 and the lower holding mechanism 12 is achieved. In this way, even if the card is inserted in the wrong orientation, the device can automatically adjust and complete the reading and writing operation, improving the user experience and simplifying the existing card reading and writing process.

[0113] In one illustrative embodiment, card 2 may include a chip-based bank card or a magnetic stripe bank card, and may also include an electronic card that enables read / write functionality by being inserted into a device.

[0114] In one illustrative embodiment, both the upper holding mechanism 11 and the lower holding mechanism 12 include a reader / writer 13.

[0115] According to the above configuration, by setting readers 13 on both the upper holding mechanism 11 and the lower holding mechanism 12, the dual readers 13 configuration allows the device to perform read and write operations on both sides of the card 2 regardless of the insertion direction, improving the user's ease of use and realizing plug-and-play functionality for the card reader / writer. This significantly optimizes the user experience, especially in application scenarios that require fast and frequent reading and writing of card 2 information.

[0116] In one illustrative embodiment, one of the upper holding mechanism 11 and the lower holding mechanism 12 includes a reader / writer.

[0117] Figure 2 The diagram schematically illustrates a perspective view of the card holder 31 in a first position according to an embodiment of the present disclosure; Figure 3A perspective view schematically showing the card holder 31 in a second position according to an embodiment of the present disclosure.

[0118] In one illustrative embodiment, such as Figure 2 and Figure 3 As shown, the drive mechanism 3 includes a bracket 31; a card holder 32, mounted within the bracket 31, adapted to lift or lower the card 2; and a drive assembly, mounted on the bracket 31, configured to simultaneously lift or lower the upper holding mechanism 11 and the card holder 32 to the same height. Thus, a common drive mechanism can be used to achieve synchronous lifting and lowering of the upper holding mechanism 11 and the card holder 32.

[0119] In one illustrative embodiment, the drive assembly includes: a lifting assembly 33 mounted on a bracket 31, the lifting assembly 33 being adapted to drive the upper holding mechanism 11 and the card holder 32 to move synchronously in the vertical direction, such that the card holder 32 has a first position lower than the lower holding mechanism 12 and a second position that lifts the card 2 to a position higher than the lower holding mechanism 12; and a rotating assembly 34 mounted on the bracket 31, the rotating assembly 34 being adapted to drive the card holder 32 to rotate relative to the read / write mechanism 1 when the card holder 32 is in the second position, so as to change the rotation direction of the card 2 located between the upper holding mechanism 11 and the lower holding mechanism 12.

[0120] According to the above configuration, the drive mechanism 3 includes a bracket 31, a card holder 32, a lifting assembly 33, and a rotating assembly 34. The card holder 32 is used to lift and lower the card. Driven by the lifting assembly 33, the card holder 32 moves vertically between a first position below the lower holding mechanism 12 and a second position above the lower holding mechanism 12. Simultaneously, the lifting assembly 33 can also drive the upper holding mechanism 11 and the card holder 32 to move synchronously. This design ensures that during the operation of the lifting assembly 33, the upper holding mechanism 11 is first disengaged from the lower holding mechanism 12, and then the card holder 32 lifts the card 2. The card 2 moves synchronously with the card holder 32 and the upper holding mechanism 11 to the second position, changing the state of the card 2 from being held by the upper holding mechanism 11 and the lower holding mechanism 12 to being located between the upper holding mechanism 11 and the lower holding mechanism 12. At this time, the rotating assembly 34 drives the card holder 32 to rotate, causing the card 2 to complete a 180-degree reversal relative to the read / write mechanism 1. This design ensures that the card 2 can be correctly rotated to the read / write position regardless of its initial insertion orientation, thereby eliminating the requirement for the card 2 insertion orientation and improving the flexibility and user convenience of the device.

[0121] In detail, after card 2 completes a 180-degree reversal, the lifting component 33 drives the card holder 32 and the upper holding mechanism 11 to descend synchronously. During the descent, card 2 is first lifted by the lower holding mechanism 12 to stop moving, and then clamped by the upper holding mechanism 11 onto the lower holding mechanism 12, thus completing the reversal of card 2.

[0122] Figure 4 A perspective view of the card holder 32 according to an embodiment of the present disclosure is shown schematically.

[0123] In one illustrative embodiment, such as Figure 4 As shown, the card holder 32 includes a chuck 321 and a connecting rod 323. The chuck 321 is used to support the card 2. One end of the connecting rod 323 is installed on the chuck 321, and the other end is installed on the lifting assembly 33.

[0124] According to the above configuration, the chuck 321 is connected to the lifting assembly 33 via the connecting rod 323, so that the chuck 321 can stably support the card 2, and the lifting assembly 33 can be used to lift and adjust the position of the card 2.

[0125] In one illustrative embodiment, such as Figure 4 As shown, the side of the chuck 321 is also provided with a first flange 322 extending upward in the vertical direction, which is suitable for restricting the movement of the card 2 while it is being supported by the card holder 32.

[0126] Specifically, the first flange 322 is disposed on both sides of the chuck 321 along the width direction of the card 2, and the distance between the two first flanges 322 is greater than the width of the card 2; furthermore, the first flange 322 can also be disposed on both sides of the chuck 321 along the length direction of the card 2, and the distance between the two first flanges 322 is greater than the length of the card 2; or the chuck 321 is provided with first flanges 322 on all four sides.

[0127] According to the above configuration, when the card 2 is lifted by the chuck 321, the card 2 will not slide and fall out of the chuck 321 due to the restriction of the first flange 322. At the same time, during the process of the rotating mechanism 34 driving the card holder 32 to rotate, the first flange 322 can support the side of the card 2 and assist in completing the reversing rotation of the card 2, thereby improving the stability of the equipment and the accuracy of the card 2 reversing.

[0128] Figure 5 A schematic front view of a card reader / writer apparatus according to an embodiment of the present disclosure is shown; Figure 6 A schematic front view of the lifting assembly 33 according to an embodiment of the present disclosure is shown.

[0129] In one illustrative embodiment, such as Figure 5 and Figure 6 As shown, the lifting assembly 33 includes: a lifting part 331, which is movably mounted on the bracket 31, and the other end of the connecting rod 323 is rotatably mounted on the lifting part 331; and a first driving part 332, which is rotatably mounted on the bracket 31, and the first driving part 332 is adapted to drive the lifting part 331 to move in the vertical direction.

[0130] According to the above configuration, the lifting assembly 33 includes a lifting part 331 and a first driving part 332. The connecting rod 323 is connected to the lifting part 331. The rotation of the first driving part 332 drives the lifting part 331 to move the connecting rod 323, thereby realizing the movement of the card holder 32 between the first position and the second position in the vertical direction.

[0131] In one illustrative embodiment, such as Figure 4 As shown, the end of the connecting rod 323 connected to the lifting part 331 is provided with a second flange 3232 extending circumferentially. The lifting part 331 is provided with a first fixing member that mates with the second flange 3232, so that the connecting rod 323 is rotatably mounted on the lifting part 331. In this way, the connecting rod 323 can be raised and lowered with the lifting part 331, and the connecting tube 323 can be rotated relative to the lifting part 331.

[0132] In one illustrative embodiment, such as Figure 5 As shown, the lifting assembly 33 also includes a connecting frame 333, which is installed between the upper holding mechanism 11 and the lifting part 331, and is suitable for moving the upper holding mechanism 11 with the lifting part 311 in the vertical direction.

[0133] According to the above configuration, the upper holding mechanism 11 is connected to the lifting part 331 through the connecting frame 333, so that the upper holding mechanism 11, the card holder 32 and the lifting part 331 move synchronously during the lifting process.

[0134] In one illustrative embodiment, such as Figure 2 and Figure 5 As shown, the connecting frame 333 includes: a horizontal frame 3331, which is installed on the lifting part 331; and two vertical frames 3332, which are respectively connected to the two ends of the horizontal frame 3331. The upper holding mechanism 11 is connected to the upper end of the two vertical frames 3332. The two vertical frames 3332 are slidably engaged with the bracket 31 to support and guide the vertical movement of the connecting frame 333.

[0135] According to the above configuration, the upper holding mechanism 11 is connected to the lifting part 331 through two vertical frames 3332 and a horizontal frame 3331, realizing the synchronous movement of the upper holding mechanism and the lifting part 331. The two vertical frames 3332 are slidably connected to the bracket 31, which not only guides the vertical movement of the lifting part 331 and the upper holding mechanism 11, but also ensures the stability and accuracy during the synchronous movement process, avoiding the occurrence of deviation.

[0136] In one illustrative embodiment, such as Figure 2 and Figure 5 As shown, the bracket 31 includes a first groove 311 extending in the vertical direction, and the vertical bracket 3332 includes a first slider 3333 slidably mounted in the first groove 311.

[0137] According to the above configuration, the bracket 31 and the vertical frame 3332 are slidably connected through the sliding engagement of the first sliding groove 311 and the first slider 3333.

[0138] In one illustrative embodiment, the first slide groove 311 is a T-shaped slide groove, and the first slider 3333 is a T-shaped slider that slides in conjunction with the T-shaped slide groove.

[0139] According to the above configuration, the T-shaped groove and T-shaped slider restrict the vertical frame 3332 from moving horizontally relative to the support during the vertical movement, thus ensuring the stability of the upper holding mechanism 11 and the lifting part 331.

[0140] In an alternative illustrative embodiment, the bracket 31 includes a first guide shaft extending in a vertical direction, and the vertical bracket 3332 includes a first guide block slidably sleeved on the first guide shaft.

[0141] In detail, a linear bearing is installed between the first guide block and the first guide shaft.

[0142] In one illustrative embodiment, such as Figure 5 and Figure 6 As shown, the first drive unit 332 includes a connecting rod 3321, and the lifting unit 331 includes a second slide groove 3311. The connecting rod 3321 is slidably inserted into the second slide groove 3311 in the horizontal direction to convert the rotation of the first drive unit 332 into the vertical movement of the lifting unit 331.

[0143] According to the above configuration, the connecting rod 3321 is slidably inserted into the second slide groove 3311 in the horizontal direction. During the rotation of the first drive unit 332, the connecting rod 3321 makes a circular motion. When the connecting rod 3321 slides in the second slide groove 3311, it drives the lifting unit 331 to move in the vertical direction through the cooperation with the second slide groove 311. This design converts the rotation of the first drive unit 332 into the vertical movement of the lifting unit 331.

[0144] In one illustrative embodiment, such as Figure 5 and Figure 6 As shown, the first drive unit 332 further includes: a first rotating wheel 3322, which is rotatably mounted on the bracket 31 in a first vertical plane; and a crank arm 3323, which is concentrically mounted on the shaft of the first rotating wheel 3322 and extends parallel to the radial direction of the first rotating wheel 3322, and is configured to rotate with the first rotating wheel 3322; wherein, a connecting rod 3321 is mounted on the end of the crank arm 3323 away from the shaft.

[0145] According to the above configuration, the first rotating wheel 3322 rotates in the first vertical plane, and the connecting rod 3321 is mounted on the first rotating wheel 3322 via the crank arm 3323. At the same time, the crank arm 3321 and the first rotating wheel 3322 are concentrically arranged on the same axis of rotation. This configuration allows the connecting rod 3321 to rotate with the first rotating wheel 3322 and generate stable circular motion, ensuring the stability and accuracy of the driven lifting part 331 moving in the vertical direction.

[0146] In one illustrative embodiment, such as Figure 6 As shown, the second slide 3311 includes an arc-shaped slide 33111 and horizontal slides 33112 located at both ends of the arc-shaped slide 33111. The radius of the arc-shaped slide 33111 is equal to the distance between the axis of the connecting rod 3321 and the axis of the first rotating wheel. When the center of the arc-shaped slide 33111 coincides with the axis of the first rotating wheel, the connecting rod 3321 slides in the arc-shaped slide 33111 under the drive of the first rotating wheel 3322 and the crank arm 3323, causing the lifting part 331 to be suspended (i.e., the lifting part 331 does not produce lifting or lowering action). On the other hand, during the sliding of the connecting rod 3321 in the horizontal slide groove 33112, and during the sliding of the connecting rod 3321 in the arc-shaped slide groove 33111 under the drive of the first rotating wheel 3322 and the crank arm 3323, or during the sliding of the connecting rod 3321 in the arc-shaped slide groove 33111 when the center of the arc-shaped slide groove 33111 is lower than the axis of the first rotating wheel 3322, the lifting part 331 moves in the vertical direction.

[0147] According to the above configuration, the connecting rod 3321 slides in the arc-shaped slide groove 33111 and the horizontal slide groove 33112 under the drive of the first rotating wheel 3322 and the crank arm 3323. This configuration utilizes the relationship between circular motion and linear motion, converting the circular motion of the connecting rod 3321 into the linear motion of the lifting part 331, thereby achieving precise lifting control and enabling the card reader / writer to provide a smooth and reliable lifting function.

[0148] In detail, when the connecting rod 3321 slides horizontally within the horizontal slide groove 33112, the circular motion of the connecting rod 3321 will drive the lifting part 331 to move vertically. Since the radius of the arc-shaped slide groove 33111 is equal to the distance between the axis of the connecting rod 3321 and the axis of the first rotating wheel 3322, when the center of the arc-shaped slide groove 33111 coincides with the axis of the first rotating wheel 3322, the sliding of the connecting rod 3321 within the arc-shaped slide groove 33111 will cause the lifting part 331 to hover, that is, remain stationary in its current position. When the connecting rod 3321 slides from the arc-shaped slide groove 33111 to the horizontal slide groove 33112, it continues to drive the lifting part 331 to move in the vertical direction, so that the center of the arc-shaped slide groove 33111 does not coincide with the axis of the first rotating wheel 3322. At this time, the connecting rod 3321 slides in the arc-shaped slide groove 33111 and the horizontal slide groove 33112, and will continue to drive the lifting part 331 to move in the vertical direction.

[0149] In one illustrative embodiment, such as Figure 6 As shown, the distance between the ends of the horizontal grooves 33112 at both ends of the arc-shaped groove 33111 is greater than or equal to the diameter of the rotation trajectory of the connecting rod 3321, that is, greater than twice the distance from the axis of the connecting rod 3321 to the axis of the first rotating wheel 3322.

[0150] According to the above configuration, the connecting rod 3321 will not be limited by the distance between the two ends of the second slide groove 3311 during the movement of the second slide groove 3311, and can still complete the circular motion with the first rotating wheel 3322.

[0151] In one illustrative embodiment, such as Figure 3 and Figure 5 As shown, the rotating assembly 34 includes: a rotating part 341, rotatably mounted on the bracket 31; and a second driving part 342, rotatably mounted on the bracket 31, the second driving part 342 being adapted to drive the rotating part 341 to rotate; wherein, the connecting rod 323 slidably passes through the rotating part 341 in the vertical direction, and the holder 32 located in the second position rotates under the drive of the rotating part 341.

[0152] According to the above configuration, the rotating part 341 can be driven to rotate by the second driving part 342, and the connecting rod 323 can slide through the rotating part 341 in the vertical direction. Therefore, when the card holder 32 is in the second position, it can rotate under the drive of the rotating part 341, realizing the rotation function of the card holder 32, so that the card holder 32 can rotate the card 2 by 180 degrees.

[0153] Figure 7 A schematic cross-sectional view of a rotating assembly according to an embodiment of the present disclosure is shown; Figure 8 A cross-sectional view schematically illustrating another operating state of the rotating assembly according to an embodiment of the present disclosure is shown. Figure 9A schematic front view of the rotating part according to an embodiment of the present disclosure is shown.

[0154] In one illustrative embodiment, such as Figure 3 , Figures 7 to 9 As shown, the second drive unit 342 includes: a second rotating wheel 3421, rotatably mounted on the bracket 31 in a first vertical plane; and a drive rod 3422, mounted on the shaft of the second rotating wheel 3421. The drive rod 3422 is configured to extend radially parallel to the second rotating wheel 3421 and rotate with the second rotating wheel 3421 in the second vertical plane. The rotating unit 341 includes: a rotating cylinder 3411, rotatably and vertically mounted on a horizontal bracket 312 connected to the bracket 31. A connecting rod 323 slidably passes through the rotating cylinder 3411. One or two intersecting guide grooves 3412 are provided on the side surface of the rotating cylinder 3411. Each guide groove 3412 is configured to extend from the top end of the first side of the rotating cylinder 3411 toward the bottom end of the second side of the rotating cylinder 3411 that is radially opposite to the first side. The center of the second rotating wheel 3421 and the center of the rotating cylinder 3411 are at the same horizontal height. The free end of the drive rod 3422 is slidably engaged with the guide groove 3412, so that the drive rod 3422 drives the rotating cylinder 3411 to rotate 180 degrees during the movement of the drive rod 3422 in the guide groove 3412.

[0155] According to the above configuration, the second drive unit 342 includes a second rotating wheel 3421 and a drive rod 3422. The drive rod 3422 is mounted on the shaft of the second drive wheel 3421 and extends radially along the shaft, rotating with the second rotating wheel 3421 in a second vertical plane. The rotating unit 341 includes a rotating cylinder 3411 with a guide groove 3412 on its surface. The guide groove 3412 is configured to extend from the top end of the first side of the rotating cylinder 3411 toward the bottom end of the second side of the rotating cylinder 3411, which is radially opposite to the first side, forming a 180-degree spiral channel. When the drive rod 3422 rotates so that its free end enters the guide groove 3412 from one end to the other end, the sliding engagement between the drive rod 3422 and the spiral guide groove 3412 enables the rotating cylinder 3411 and the holder 32 to rotate 180 degrees.

[0156] Furthermore, the center of the second rotating wheel 3421 and the center of the rotating cylinder 3411 are located at the same horizontal height. This arrangement ensures the consistency of the driving angle of the drive rod 3422 on the upper and lower parts of the rotating cylinder 3411 and the sliding state in the guide groove 3412 during rotation, simplifying the structure of the rotating assembly 34. The sliding state includes the angle at which the drive rod 3422 enters the guide groove 3412 during driving, the length of its insertion into the guide groove 3412, and the angle at which the rotating cylinder 3411 is driven to rotate.

[0157] In detail, when a guide groove 3412 is provided on the side surface of the rotating cylinder 3411, after the driving rod 3422 drives the rotating cylinder 3411 to complete one rotation, the second rotating wheel 3421 rotates in the opposite direction, and the driving rod 3422 rotating in the opposite direction can drive the rotating cylinder 3411 to complete the next rotation.

[0158] In detail, when two intersecting guide grooves 3412 are provided on the side surface of the rotating cylinder 3411, the driving rod 3422 cooperates with the two guide grooves 3412 respectively. The driving rod 3422 does not need to change direction and can meet the first and subsequent rotation requirements of the rotating cylinder 3411 by rotating in one direction.

[0159] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the horizontal bracket 312 is constructed in a ring shape and extends in the vertical direction. The rotating cylinder 3411 is rotatably sleeved on the horizontal bracket 312. The cylindrical horizontal bracket 312 and the rotating cylinder 3411 are concentrically arranged.

[0160] According to the above arrangement, the horizontal bracket 312 is designed to be annular and extend vertically, and is concentrically arranged with the rotating cylinder 3411, so that the rotating cylinder 3411 can rotate around the central axis of the horizontal bracket 312, providing stable support for the rotating cylinder 3411. Through this concentric arrangement, the rotating assembly 34 can provide a smooth and reliable rotation function.

[0161] In one illustrative embodiment, such as Figures 7 to 9 As shown, the rotating cylinder 3411 also includes a third flange 3415, which is suitable for cooperating with the second fixing member to rotatably mount the rotating cylinder 3411 on the horizontal bracket 312.

[0162] According to the above configuration, by utilizing the cooperation of the third flange 3415 and the second fixing member, the movement of the rotating cylinder 3411 in the vertical direction is restricted without affecting the rotation of the rotating cylinder 3411.

[0163] Figure 10 A top view of the rotating part according to an embodiment of the present disclosure is shown schematically.

[0164] In one illustrative embodiment, such as Figure 4 , Figure 10As shown, the rotating cylinder 3411 and the connecting rod 323 are concentrically arranged; a groove 3414 extending vertically is provided on one of the inner surfaces of the rotating cylinder 3411 and the connecting rod 323, and a rib 3231 that mates with the groove 3414 is provided on the other inner surface of the rotating cylinder 3411 and the connecting rod 323 to limit the relative position of the rotating cylinder 3411 and the connecting rod 323 in the circumferential direction, so that the connecting rod 323 rotates under the drive of the rotating cylinder 3411, and allows the connecting rod 323 to slide vertically under the cooperation of the groove 3414 and the rib 3231.

[0165] According to the above arrangement, the rotating cylinder 3411 and the connecting rod 323 are concentrically arranged. The relative position of the rotating cylinder 3411 and the connecting rod 323 in the circumferential direction is restricted by the interlocking of the groove 3414 and the convex rib 3231, so that the rotating cylinder 3411 drives the connecting rod 323 to rotate synchronously during rotation, thereby realizing the 180-degree rotation of the holder 32. At the same time, both the groove 3414 and the convex rib 3231 are designed to extend vertically. This design allows the connecting rod 323 to slide vertically under the cooperation of the groove 3414 and the convex rib 3231.

[0166] Figure 11 A schematic cross-sectional view of the rotating assembly in another operating state according to an embodiment of the present disclosure is shown.

[0167] In one illustrative embodiment, such as Figure 10 and Figure 11 As shown, the rotating part 341 also includes two limiting plates 3413, which are installed at the upper and lower ends of the rotating cylinder 3411. Each limiting plate 3413 has a limiting groove 34131 that is recessed inward on its radially opposite sides. The second driving part 342 also includes a limiting strip 3423, which is installed on the shaft of the second rotating wheel 3421 at a distance from the driving rod and rotates with the second rotating wheel 3421 in the second vertical plane. The limiting strip 3423 is configured to enter a limiting groove 34131 of at least one limiting plate 3413 during the vertical movement of the lifting part 331 to limit the rotation of the rotating cylinder 3411.

[0168] According to the above configuration, the limiting bar 3423 can rotate in the second vertical plane with the second drive wheel 3421. It is configured to rotate into the limiting groove 34131 of at least one limiting plate 3413 during the vertical movement of the lifting part 331, thereby limiting the rotation of the rotating cylinder 3411. This configuration limits the rotation of the rotating cylinder 3411 when the card holder 2 is not in the second position, ensuring the stability of the card reader / writer during the operation of rotating the card 2. The cooperation between the limiting bar 3423 and the limiting plate 3413 provides precise rotation restriction, so that the rotating cylinder 3411 can only be driven to rotate under the set conditions (i.e., the card holder 32 is in the second position).

[0169] In one illustrative embodiment, such as Figure 11 As shown, the limiting bar 3423 is constructed in an arc shape, and the center of the arc of the limiting bar 3423 coincides with the axis of the second rotating wheel 3421.

[0170] According to the above configuration, when the limiting strip 3423 rotates into the limiting groove 34131 in the second vertical plane, each part of the limiting strip 3423 is accurately positioned within the limiting groove 34131 of the limiting plate 3413. This ensures that the limiting strip 3423 maintains the correct position during rotation, thereby effectively limiting the rotation of the rotating cylinder 3411.

[0171] In one illustrative embodiment, such as Figure 11 As shown, the radius of the limiting strip 3423 is greater than the straight-line distance from the outer edge of the limiting plate 3413 to the axis of rotation of the second rotating wheel 3421 and less than the shortest distance from the center of the limiting strip 3423 to the side surface of the rotating cylinder 3411.

[0172] According to the above configuration, when the limiting bar 3423 rotates to the range of the limiting plate 3413, it can enter the limiting groove 34131 to cooperate with the limiting groove 34131 to limit the rotation of the rotating cylinder 3411. At the same time, during the rotation limiting process, the limiting bar 3423 and the rotating cylinder 3411 are prevented from contacting and rubbing against each other, thus avoiding damage to the device.

[0173] In one illustrative embodiment, such as Figure 11 As shown, the limiting strip 3423 is configured to be located simultaneously in two limiting grooves 34131 on the same side of the upper and lower ends of the rotating cylinder 3411.

[0174] According to the above setting method, it is ensured that the limiting bar 3423 rotates out of the first limiting groove 34131 before it rotates from one limiting groove 34131 at one end of the rotating cylinder 3411 into the other limiting groove 34131 at the other end, which causes the rotating cylinder 3411 to be unable to be restricted and misalignment occurs.

[0175] In detail, the chord length of the arc-shaped limiting strip 3423 is greater than the distance between the two limiting plates 3413, and the chord height of the limiting strip 3423 is less than the radial depth of the limiting groove 34131 of the limiting plate 3413.

[0176] In one illustrative embodiment, such as Figure 7 , Figure 8 , Figure 11 As shown, there are two drive rods 3422 and two limit bars 3423. The two drive rods 3422 and the two limit bars 3423 are configured to be alternately installed on the shaft of the second rotating wheel 3421 at equal intervals.

[0177] According to the above configuration, a limit bar 323 and an adjacent drive rod 322 form a group, so that the second rotating wheel 3421 can rotate half a turn (i.e., 180 degrees) to meet the requirements of single rotation reversal and limit of the rotating cylinder 3411, shortening the rotation stroke of the second rotating wheel 3421 and improving the service life of the second drive unit 342.

[0178] In one illustrative embodiment, such as Figure 9 and Figure 10 As shown, the two guide grooves 3412 have opposite spiral directions on the surface of the rotating cylinder 3411 and intersect at the middle, and the two ends of each guide groove 3412 are respectively located at two limiting grooves 34131 that are radially opposite to each other on the two limiting plates 3413.

[0179] According to the above configuration, the port of the guide groove 3412 is located at the same position as the upper limit groove 34131 of the limit plate 3413. The drive rod 3422 will not be blocked by the limit plate 3413 during the process of rotating into the guide groove 3412. The drive rod 3422 can rotate into the guide groove 3412 through the limit groove 34131 and then cooperate with the guide groove 3412 to drive the rotating cylinder 3411 to rotate.

[0180] In one illustrative embodiment, such as Figure 7 As shown, the drive rod 3422 and the limiting strip 3423 are configured such that, during the period from when the drive rod 3422 rotates from one end of the rotating cylinder 3411 into the limiting groove 34131 to when it rotates into the guide groove 3412 located at the same position, the limiting strip 3423 rotates out of the limiting groove 34131 at the other end of the rotating cylinder 3411, and / or during the period from when the limiting strip 3423 rotates out of one end of the guide groove 3412 into the limiting groove 34131 at the same position to when it rotates out of the limiting groove 34131, the drive rod 3422 rotates into the limiting groove 34131 at the other end.

[0181] According to the above configuration, the distance between the drive rod 3422 and the adjacent limiting strip 3423 is limited, so that the second drive part 342 can be seamlessly connected between driving the rotation part 341 to rotate and limiting the rotation part 341 to rotate, ensuring that the card reader / writer can accurately control the movement state of the rotation part 341 during operation.

[0182] Figure 12 The schematic diagram illustrates the transmission relationship between the lifting assembly and the rotating assembly according to an embodiment of the present disclosure.

[0183] In one illustrative embodiment, such as Figure 12As shown, the drive mechanism 3 further includes: a conveyor belt 36, which surrounds the first rotating wheel 3322 and the second rotating wheel 3421; and a drive motor 35, which is mounted on one of the first rotating wheel 3322 and the second rotating wheel 3421 to drive the other of the first rotating wheel 3322 and the second rotating wheel 3421 to rotate via the conveyor belt 36.

[0184] According to the above configuration, the conveyor belt 36 wraps around the first rotating wheel 3322 and the second rotating wheel 3421, while the drive motor 35 is mounted on either the first rotating wheel 3322 or the second rotating wheel 3421 to drive the other rotating wheel to rotate via the conveyor belt 36. The conveyor belt 36 ensures that the first rotating wheel 3322 and the second rotating wheel 3421 rotate synchronously under the drive of the drive motor 35. This guarantees the smooth connection between the lifting and lowering of the drive mechanism 11 or the card 2 and the rotational reversal of the card 2, simplifies the structure of the drive mechanism 3, and avoids the possibility of card 2 reversal failure due to discontinuous connection between lifting and turning operations.

[0185] In one illustrative embodiment, the drive mechanism 3 includes a chain, and the first rotating wheel 3322 and the second rotating wheel 3421 are connected by chain drive.

[0186] In an alternative illustrative embodiment, the first rotating wheel 3322 and the second rotating wheel 3421 can be driven to rotate synchronously by two drive motors 35.

[0187] In one illustrative embodiment, such as Figure 2 As shown, when the connecting rod 3321 rotates to a position directly below the axis of rotation of the first rotating wheel 3322, the lifting part 331 is in the lowest position. At this time, the connecting rod 3321 is in the middle position of the arc-shaped slide groove 33111, and the center of the arc-shaped slide groove 33111 is below the axis of the first rotating wheel 3322. At the same time, the bracket 32 ​​is in the first position. This is the initial state of the lifting assembly 33. The connecting rod 3321 rotates one revolution to complete the lifting step in one reversing operation.

[0188] Detailed, such as Figure 2 and Figure 11 As shown, when the lifting assembly 33 is in its initial state, the limiting strip 3423 is located in the center of the rotating cylinder 3411, and simultaneously engages with the two limiting grooves 34131 on the side of the limiting plate 3413 at the upper and lower ends of the rotating cylinder 3411 near the second drive part 342. At this time, the limiting strip 3423 is symmetrical in the upper and lower parts in the horizontal direction.

[0189] In one illustrative embodiment, such as Figure 2 and Figure 3As shown, the drive motor 35 is connected to the first rotating wheel 3322, and the diameter of the second rotating wheel 3421 is constructed to be twice the diameter of the first rotating wheel 3322; the limit bar 3423 and the drive rod 3422 are both set in pairs; two guide grooves 3412 are provided on the side surface of the rotating cylinder 3411, so that when the first rotating wheel 3322 rotates one revolution, the second rotating wheel rotates half a revolution.

[0190] The specific operation flow of the drive mechanism 3 is as follows: Starting from the initial state of the lifting assembly 33, the drive motor 35 drives the first rotating wheel 3322 to rotate clockwise or counterclockwise, while the transmission belt 36 drives the second rotating wheel 3421 to rotate. Driven by the first rotating wheel 3322 and the crank arm 3323, the connecting rod 3321 rotates from vertically below the axis of rotation of the first rotating wheel 3322, performing a circular motion. The two limit bars 3423 and the two drive rods 3422 rotate with the second rotating wheel 3421, alternately cooperating with the rotating part 341 to complete the operation of limiting and driving the rotating part 341 to rotate.

[0191] In detail, as the connecting rod 3321 rotates and slides within the second slide groove 3311, the driving lifting part 331 moves upward from its lowest position. When the center of the arc-shaped slide groove 33111 coincides with the axis of the first rotating wheel 3322, the lifting part 331 reaches its highest position. The lifting part 331 completes the movement of the card holder 32 from the first position to the second position. Simultaneously, the connecting rod 3321 slides from the horizontal slide groove 33112 to the arc-shaped slide groove 33111. At this time, the driving rod 3422 rotates into the limiting groove 34131 at one end, and the limiting strip 3423 rotates out of the limiting groove 34131 at the other end (e.g., ...). Figure 7 (As shown).

[0192] During the sliding process of the connecting rod 3321 in the arc-shaped slide groove 33111, the lifting part 331 is suspended, the bracket 32 ​​is always in the second position, and at the same time, a drive rod 3422 cooperates with a guide groove 3412 on the side surface of the rotating cylinder 3411 to drive the rotating cylinder 3411 to rotate, thereby driving the bracket 32 ​​in the second position to complete a 180-degree reversal rotation.

[0193] In detail, the central angle of the arc-shaped slide 33111 is greater than or equal to twice the rotation angle during the engagement of the drive rod 3422 and the guide groove 3412.

[0194] When the connecting rod 3321 slides from the arc-shaped slide groove 33111 to the horizontal slide groove 33112, the drive rod 3422 rotates out of the limiting groove 34131 at the end opposite to the rotating end, and the limiting bar 3423 rotates into the limiting groove 34131 at the other end.

[0195] The connecting rod 3321 continues its circular motion, driving the lifting part 331 to move downwards to the lowest position and return to its initial state. The lifting part 331 completes the movement of the bracket 32 ​​from the second position to the first position. At this time, another limiting bar 3423 cooperates with the limiting groove 34131 to restrict the rotating part 341, completing one reversing operation.

[0196] Furthermore, during the next reversing operation, when the connecting rod 3321 performs its next circular motion, the limiting strip 3423 and limiting groove 34131, the drive rod 3422 and guide groove 3412, which did not engage in the previous circular motion, engage in the current reversing process to complete the reversing.

[0197] In one illustrative embodiment, such as Figure 2 and Figure 3 As shown, the upper holding mechanism 11 and / or the lower holding mechanism 12 include a support frame 111 and multiple sets of transmission parts 112 arranged side by side on the support frame 111, the transmission parts 112 being adapted to receive and transport the card 2.

[0198] In one illustrative embodiment, such as Figure 2 and Figure 3 As shown, the transmission unit 112 includes a transmission wheel 1121, which is rotatably mounted to the upper holding mechanism 11 and / or the lower holding mechanism 12 via a configured mounting bracket 1122.

[0199] According to the above configuration, the upper holding mechanism 11 and / or the lower holding mechanism 12 can effectively receive and transport the card 2, improving the efficiency and accuracy of the device.

[0200] In one illustrative embodiment, the transmission unit 112 includes a plurality of rotating rollers and a conveyor belt sleeved on the outside of the rotating rollers, the rotating rollers being rotatably mounted on the support frame 111.

[0201] In one illustrative embodiment, such as Figure 1 As shown, it also includes a monitoring mechanism 4, which is used to monitor whether the drive mechanism 3 is in the initial position in front of the card 2 received by the read / write mechanism 1.

[0202] According to the above configuration, the monitoring mechanism 4 is configured to ensure that when the driving mechanism 3 needs to complete the reversing operation, the driving mechanism 3 is in the initial position so as to be able to complete the reversing operation on the received card 2.

[0203] In one illustrative embodiment, the monitoring mechanism 4 includes multiple infrared sensors suitable for identifying whether the lifting unit 331, the second drive unit 342, etc., are in a predetermined position.

[0204] According to the above configuration, the monitoring mechanism 4 uses infrared sensors arranged around the drive mechanism 3 to monitor whether key components are in the predetermined positions, ensuring that the drive mechanism 3 is in the initial position in front of the receiving card 2. If the component position deviates, the monitoring mechanism will send an adjustment signal, ensuring the safety of read / write operations and the reliability of the device.

[0205] Figure 13 A schematic diagram illustrating the structure of an automated trading system according to an embodiment of the present disclosure is shown. Figure 14 A schematic diagram illustrating another operational state of the automated trading system according to an embodiment of the present disclosure is shown. Figure 15 A schematic diagram illustrating a structural schematic of an automated trading system in another operating state according to an embodiment of the present disclosure is shown.

[0206] Another aspect of the embodiments of this disclosure provides an automated trading system, such as... Figures 13 to 15 As shown, it includes: the card reader / writer device described above; a posture recognition device 5 configured to identify whether the card 2 is being delivered to the reader / writer mechanism 1 in the correct direction; and a controller 6 configured to control the drive mechanism 3 to operate to rotate the card 2 180 degrees when the posture recognition device 5 identifies that the card 2 is being delivered to the reader / writer mechanism 1 in the wrong direction.

[0207] Based on the above configuration, the posture recognition device 5 can accurately identify whether the card 2 is being fed to the reader / writer 1 in the correct orientation, ensuring that the card 2 can be read correctly. If the posture recognition device 5 detects that the card 2 is being fed to the reader / writer 1 in the wrong orientation, the controller 6 can respond quickly and control the drive mechanism 3 to rotate the card 2 180 degrees so that it faces the reader / writer 1 correctly. This design improves the automation level of the system, avoids read / write failures caused by incorrect card orientation, and enhances the overall system performance and user experience.

[0208] In one illustrative embodiment, the posture recognition device 5 includes an optical camera 51 adapted to capture images of the card 2 and analyze the orientation of the card 2 using image processing techniques.

[0209] Detailed, such as Figure 13 As shown, the optical camera 51 is connected to the controller 6 for communication. It transmits the captured image of the card 2 to the controller 6 for image processing and analysis to determine the card orientation of the card 2.

[0210] In one illustrative embodiment, the controller 6 is also configured to control the drive mechanism 3 to rotate the card 2 180 degrees when the reader 13 fails to read or write information to the card 2.

[0211] In detail, after the reading and writing mechanism 1 receives the card 2, the reader 13 begins to read and write information on the card 2. If the reader 13 fails to read the card successfully after a preset time, it may be due to the card 2 being in the wrong orientation or the card 2 being damaged. At this time, the controller 6 controls the drive mechanism 3 to rotate the card 2 180 degrees.

[0212] According to the above configuration, when the posture recognition device 5 fails to identify the card orientation error of card 2, card 2 is received by the read / write mechanism 1, but the reader / writer 13 still fails to perform information read / write. The controller 6 will trigger the operation of the drive mechanism 3 to rotate card 2 180 degrees. This design provides an automated fault handling mechanism. Even if the read / write fails, the system can automatically adjust the position of card 2, providing the user with the possibility of trying to read / write again.

[0213] In one illustrative embodiment, such as Figure 13 As shown, the automated transaction system also includes: an inlet / outlet 7; and a conveying device 8, configured to connect to the inlet / outlet 7, adapted to convey a card 2 inserted into the inlet / outlet 7 to the reader / writer 1 or to convey a card 2 conveyed out of the reader / writer 1 to the inlet / outlet 7.

[0214] In one illustrative embodiment, such as Figure 12 As shown, the conveying device 8 includes multiple conveying sections, which are spaced apart between the inlet / outlet 7 and the reading / writing mechanism 1. It is suitable for clamping the card 2 inserted into the inlet / outlet 7 and conveying the card 2 to the reading / writing mechanism 1, as well as clamping the card 2 withdrawn from the reading / writing mechanism 1 and conveying it to the inlet / outlet 7.

[0215] In one illustrative embodiment, such as Figure 12 As shown, each conveying unit includes two upper conveying wheels and two lower conveying wheels arranged opposite each other. The upper and lower conveying wheels cooperate to clamp the card 2 and convey the card 2 along a set direction.

[0216] In one illustrative embodiment, both the upper and lower conveyor wheels are made of elastic material to elastically deform during the clamping of the card 2, thereby increasing the friction between the wheel and the card 2 without damaging the card 2 and ensuring stable operation during the conveying process.

[0217] In one illustrative embodiment, such as Figures 13 to 15 As shown, multiple optical cameras 51 are provided, which are respectively installed on the upper and lower sides of the conveying device 8 and above the upper holding mechanism 11.

[0218] According to the above configuration, when card 2 is being transported by the conveying device 8, the optical camera 51 can capture the image of card 2 to identify the card orientation. At the same time, after the reading and writing mechanism 1 receives card 2, it can still capture the image of card 2 again to identify the card orientation, thereby increasing the number of times the card orientation is identified and the accuracy of the identification.

[0219] In one illustrative embodiment, such as Figure 13 As shown, the automated transaction system also includes a magnetic sensor 9, installed between the entrance / exit 7 and the reader / writer 1, which is suitable for identifying cards 2 with magnetic stripes.

[0220] In detail, when a card 2 with a word tag is inserted into the entrance / exit 7, the magnetic sensor 9 can identify that a card 2 has been inserted, and at the same time determine the card orientation of the card 2 based on the position of the identified word tag.

[0221] In one illustrative embodiment, such as Figure 13 As shown, the magnetic sensor 9 is installed between the entrance / exit 7 and the conveying device. It is suitable for identifying the card 2 with a magnetic strip inserted into the entrance / exit 7. When the magnetic strip of the card 2 is detected, the controller 6 controls the conveying device 8 to convey the card 2 to the reading / writing mechanism 1.

[0222] In detail, the magnetic sensor 9 works based on magnetic field induction technology. It can detect changes in the magnetic field generated by the magnetic stripe of card 2, thereby determining whether card 2 has a magnetic stripe and its position. When the magnetic sensor 9 detects the magnetic stripe of card 2, it sends a signal to the controller 6. Upon receiving the signal, the controller 6 controls the conveying device 8 to transport card 2 with the magnetic stripe to the reader / writer 1. The magnetic sensor 9 enables the automated transaction system to automatically identify card 2 with a magnetic stripe and correctly transport it to the reader / writer 1 for further processing. This improves the system's automation level, reduces the complexity of user operations, and also enhances the overall performance and reliability of the system.

[0223] The embodiments of this disclosure also provide a method for implementing automated trading using the above-described automated trading system, comprising the following steps:

[0224] Step A: Identify the card orientation of card 2.

[0225] Step B: If the card is in the wrong orientation, lift the upper holding mechanism 11 away from the lower holding mechanism 12, raise the card 2 between the upper holding mechanism 11 and the lower holding mechanism 12, and then rotate the card 2 180 degrees.

[0226] Step C: Perform information reading and writing on card 2.

[0227] In one illustrative embodiment, step A further includes using an optical camera 51 to perform image recognition on the card 2 to determine the card orientation of the card 2, and using a magnetic sensor 9 to identify the card 2, and when a magnetic strip is detected inside the card 2, determining the card orientation of the card 2 based on the position of the magnetic strip.

[0228] In one illustrative embodiment, the steps further include lifting the upper holding mechanism 11 away from the lower holding mechanism 12 when the reader 13 fails to perform information reading or writing on the card 2, and then raising the card 2 between the upper holding mechanism 11 and the lower holding mechanism 12 and rotating the card 2 180 degrees.

[0229] In one illustrative embodiment, the method further includes step D, which involves conveying card 2 out of the read / write mechanism 1 after performing information reading and writing on card 2, and conveying card 2 out of the read / write mechanism 1 if reading and writing still fails when card 2 is rotated 180 degrees.
