Description

Technical Field

[0002] With the rapid development of automated business processes in the service and financial industries, the use of automatic card receiving and issuing machines has provided convenience for people to conduct business on their own. When issuing cards, automatic card receiving and issuing machines generally need to produce a blank or white card and then automatically issue the card. However, whether receiving or issuing a card, the automatic card receiving and issuing machine needs to check and verify the card surface pattern and information to avoid incomplete or blurred patterns or information.

[0003] In the process of issuing or receiving cards, most existing automatic card receiving and dispensing machines use a card picking wheel that directly contacts the card. The card picking wheel rotates and generates friction with the card surface to drive the card to move until the card is sent and received. In this way, when the card pattern or information is detected and verified, the contact point between the card and the card picking wheel is blocked, resulting in incomplete reading of the card pattern or information.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] Example 1

[0057] See Figures 1 to 3As shown, this embodiment provides a card detection device, including: a bracket for supporting the various components of the entire card detection device, including side support plates 1 and a bottom support plate on both sides, a channel is formed between the support plates on both sides, and card inlet and card outlet are set at both ends of the side support plates 1 on both sides; a card picking wheel 2 component, including a first card picking wheel 2 component and a second card picking wheel 2 component, the first card picking wheel 2 component is fixedly installed at the card inlet, and the second card picking wheel 2 component is fixedly installed at the card outlet, the two ends of the card picking wheel 2 component are respectively fixedly connected to the side support plates 1 on both sides, and can rotate around their own transmission shafts, and one end is fixedly connected To the power synchronous pulley 9, a card picking wheel 2 for frictionally transmitting the card is fixedly provided in the middle thereof; the card pushing assembly is fixedly mounted on the bracket and is located in the channel between the side support plates 1 on both sides, and is located between the first card picking wheel 2 assembly and the second card picking wheel 2 assembly, and can reciprocate in the channel of the bracket; the detection assembly is fixedly mounted on the side support plates 1 on both sides of the bracket, for detecting the position of the card and the card pushing assembly in the card detection device, and serves as the starting switch of the card pushing assembly; the shooting assembly 5 is fixedly mounted above the middle of the channel, for completely shooting the graphic information on the surface of the card.

[0058] See Figure 2 and Figure 3 As shown, the angles at which the side support plates 1 on both sides connect to the bottom support plate are both right angles. The side support plates on both sides are provided with card guides for positioning the card movement to prevent the card from shifting during movement, resulting in incomplete card images.

[0059] The first card picking wheel 2 assembly and the second card picking wheel 2 assembly both include a driving wheel and a driven wheel, one end of the driving wheel is fixedly connected to the power synchronous pulley 9, and the middle part of the transmission shaft of the driving wheel and the driven wheel is fixedly provided with a card picking wheel 2 for frictionally transmitting the card.

[0060] The driving wheel is positioned below the driven wheel, with the distance between the driving wheel's card pickup roller 2 and the driven wheel's card pickup roller 2 being less than the thickness of the card. A card pickup roller 2 is fixedly mounted in the middle of the drive shaft of each of the driving and driven wheels, for frictionally conveying the card. At the card inlet, the card enters the gap between the driving and driven wheel's card pickup rollers 2. The two rotating card pickup rollers 2 clamp the card, using friction to drive the card in the direction of rotation of the driving wheel's card pickup roller 2, pushing the card into the card detection device, which captures and detects the graphic information on the card surface and performs verification.

[0061] The card pusher assembly includes a card loading platform 3, a pusher head 31, and a power mechanism 10. The pusher head 31 is fixedly mounted at both ends of the card loading platform 3. The card loading platform 3 is aligned with the driving wheel and the driven wheel. That is, when a card enters the card inlet, part of the card is clamped between the driving wheel and the driven wheel, while part falls onto the card loading platform. At this time, the card is placed horizontally. The power mechanism 10 is fixedly mounted at the bottom end of the card loading platform relative to its surface.

[0062] The power mechanism 10 includes a push rod, a belt, a guide rail, and a drive pulley. One end of the push rod is fixedly connected to the card support platform, and the other end is fixedly connected to the belt. The belt is mounted within the guide rail, and the drive pulley drives the belt. By controlling the operating speed of the drive pulley, the pushing speed of the push rod is controlled, thereby controlling the movement speed of the card pushing device.

[0063] The power mechanism 10 includes a retractable push rod and a drive motor. The push rod is positioned within the channel, with its ends facing the card entry and exit ports, respectively. One end of the push rod is connected to the drive motor's rotating shaft, and the other end is fixedly connected to the bottom end of the card push assembly via a connector. The drive motor controls the speed at which the push rod retracts and retracts, thereby controlling the reciprocating speed of the card push assembly.

[0064] The length of the card pusher assembly is less than the distance between the card inlet and the card outlet. The length of the card support platform 3 is greater than or equal to the length of the card. The width of the card support platform 3 is less than or equal to the width of the card. The width of the card support platform 3 at both ends is less than the width in the middle, and the length of the two ends is greater than or equal to the sum of the pusher head length and the card picking wheel diameter. The card can be placed completely on the card support platform, and card entry and exit can proceed smoothly without hindering the movement of the card.

[0065] See Figure 5 Both ends of the card supporting platform are provided with lower limit grooves, an elastic component is provided in the lower limit groove, and a rotating component is provided on the side of the lower limit groove away from the card supporting platform. The blocking component includes a vertical push plate and a connecting plate connecting the top of the vertical push plate and the rotating component. The elastic component is located between the connecting plate and the bottom of the lower limit groove.

[0066] The push head 31 includes a blocking member and an elastic member. One end of the blocking member is fixedly connected to one end of the card carrier 3, and the other end of the blocking member forms a height difference with the card carrier 3. One end of the elastic member is fixedly connected to the card carrier 3, and the other end is fixedly connected to a side of the blocking member facing the card carrier 3. The push head 31 is fixedly installed at the middle of the edge of both ends of the card carrier 3. The card inlet and the card outlet are fixedly provided with a blocking piece 6 for pressing down the push head 31 at the end of the card pushing assembly, and the two ends of the blocking piece 6 are fixedly connected to the side support plates 1 on both sides. The height of the blocking piece 6 relative to the bottom support plate is higher than the height of the card carrier 3 relative to the bottom support plate. The power mechanism 10 includes a pushing rod, a screw rod and a driving motor 10. One end of the pushing rod is fixedly connected to the card supporting platform 3. The other end of the pushing rod is provided with a screw rod ring. The screw rod ring is sleeved on the screw rod. The screw rod is fixedly connected to the bottom support plate. One end of the screw rod is connected to the driving motor 10. When started, the driving motor 10 drives the screw rod to rotate. The screw rod ring drives the screw rod ring to move toward the end direction of the screw rod under the rotation of the screw rod, that is, drives the card pushing assembly to perform reciprocating motion. The card pushing assembly transmits it to the card inlet through its power mechanism 10, and the baffle 6 presses down the blocking member of the push head 31, which drives the elastic member to contract. At this time, the height difference between the other end of the blocking member of the push head 31 and the card supporting platform 3 becomes smaller until it is flush with the baffle 6 in the horizontal direction. At this time, the card is passed from the card inlet through the baffle 6 and the pressed push head 31 to the card supporting platform 3, and is driven by the card rubbing wheel 2 to be completely placed on the card supporting platform 3. The pressed push head 31 bounces up to restore its original shape and blocks the card. Driven by the power mechanism 10, the card moves toward the card outlet together with the card supporting platform 3.

[0067] The detection assembly includes an optical coupler detector, the height of which relative to the bottom support plate is equal to the height of the card push assembly relative to the bottom support plate. The optical coupler detectors are fixedly mounted at the card entry and exit ports to detect the entry and exit of cards, and are also located in the middle of one of the side support plates 1 to detect the activation of the card push assembly. Two optical couplers are located in the middle of the side support plate 1, with the distance between the card entry port and the optical coupler detector near the entry port being equal to the distance between the optical coupler detector near the exit port and the card push assembly being equal to the length of the card. The card push assembly also includes a sensor plate 7 fixedly mounted on the side edge of the card carrier 3 near the side support plate 1. The detection assembly also includes a position sensor 42 fixedly mounted in the middle of the other side support plate 1 near the sensor plate 7 to detect the position of the card push assembly. The height of the sensor plate 7 relative to the bottom support plate is less than the height of the position sensor 42 relative to the bottom support plate. There are three position sensors 42, each equidistantly located in the middle of the side support plate 1. In a preferred embodiment, when the card push assembly is activated, the sensor plate 7 moves along with the card push assembly and passes the position sensor 42, at which point the position sensor 42 receives information about the card push assembly's position. The optical coupler detector is positioned near the end of the baffle 6. When the optical coupler detector detects a card entering, the card push assembly is activated, moving to the card entrance. The pusher head 31 of the pusher assembly is pressed downward by the baffle 6, and the card is transferred to the pusher assembly via the card picking wheel 2, whereupon the pusher head 31 rises and resumes its position.

[0068] The shooting component 5 is fixedly connected to the side support plate 1 through a connecting piece, and the shooting picture of the shooting component 5 includes the picture of the entire card supporting platform 3. The shooting component 5 is a camera.

[0069] The card detection device further comprises an illumination mechanism 8, which is provided on the top edge of the side support plates 1 on both sides. The illumination mechanism 8 is an LED fill light.

[0070] The card detection device further comprises a fixed base, one side of which is fixedly connected to the bottom support plate, and the other side of which is fixedly mounted on the working platform.

[0071] The specific working principle of the card detection device in the embodiment is as follows:

[0072] Initially, when the optical coupler detector at the card inlet of the card detection device of this embodiment detects that a card has entered, the power synchronous pulley 9 and the power mechanism 10 of the card pushing assembly are started at the same time, and the camera and LED fill light are turned on. The driving wheels of the first card picking wheel 2 assembly and the second card picking wheel 2 assembly are driven by the power synchronous pulley 9 to rotate the card picking wheels 2 of the two sets of driving wheels, while the card picking wheels 2 of the driven wheels do not rotate. The card pushing assembly is driven by the power mechanism 10 to move to the card inlet, and the push head 31 of the card pushing assembly close to the card inlet is pressed under the baffle 6, and the entire device is in a state of waiting for card entry.

[0073] Next, the front end of the card passes through the baffle 6 and the first optical coupler detector 411 at the card inlet, and then passes through the push head 31 to enter the supporting area of the card supporting platform 3, and then enters the friction transmission area between the driving wheel and the driven wheel of the first card picking wheel 2 assembly. The card is clamped between the above two card picking wheels 2. As the driving wheel rotates, the card is driven to move toward the card outlet. At the same time, the card picking wheel 2 of the driven wheel used to clamp and position the card also rotates with the movement of the card. After the card passes through the friction transmission area, when the front end of the card passes through the second optical coupler detector 412 again, the card detection device starts the card pushing assembly again and drives it to move toward the card outlet. At this time, the card has been completely placed on the card supporting platform 3, and the pushing head 31 pops up to block the rear end of the card. After the card is transmitted to the shooting detection area by the card pushing assembly, when the front end of the card passes through the third optical coupler detector 413 again, the card detection device stops starting the card pushing assembly, so that the card is placed in the shooting detection area and pauses. The camera takes a picture of the image and text on the entire card surface and transmits it to the background for detection. After a pause, the card pushing assembly is started again to drive the card pushing assembly to continue moving toward the card outlet. The pushing head 31 near the card outlet is pressed down by the baffle 6 at the card outlet, and the card enters the friction transmission area between the active wheel and the driven wheel of the second card picking wheel 2 assembly. At this time, the card passes the fourth optical coupler detector 414, and the card is transmitted out of the card outlet, and the next card begins to enter the card detection device for detection. When the second and third photocoupler detectors 413 are not blocked by the card, the card pushing assembly is driven to move toward the card inlet, and the card detection device returns to its initial state.

[0074] The working principle of the second photocoupler detector 412 and the third photocoupler detector 413 cooperating with each other to control the movement of the card pushing assembly is as follows: when the second photocoupler detector 412 is blocked by the card and the third photocoupler detector 413 is not blocked by the card, the card pushing assembly starts to move from the card inlet to the card outlet; when the second photocoupler detector 412 is blocked by the card and the third photocoupler detector 413 is blocked by the card, the card pushing assembly stops moving from the card inlet to the card outlet, and the card is photographed and detected at this time; when the second photocoupler detector 412 is not blocked by the card and the third photocoupler detector 413 is blocked by the card, the card pushing assembly continues to move from the card inlet to the card outlet; when the second photocoupler detector 412 is not blocked by the card and the third photocoupler detector 413 is not blocked by the card, the card pushing assembly starts to move from the card outlet to the card inlet, that is, the card pushing device returns to the card inlet;

[0075] When the above-mentioned card pushing assembly transmits the card, when the sensing piece 7 on the side of the card pushing assembly passes through the three position sensors 42 equidistantly arranged on the side support plate 1, the position sensor 42 is used to detect the moving direction and status of the card pushing assembly. For example, when the sensing piece 7 passes through the three position sensors 42 in sequence along the card exit direction, it can be known that the card pushing assembly is moving along the card exit direction; when the sensing piece 7 passes through the three position sensors 42 in sequence along the card entry direction, it can be known that the card pushing assembly is moving along the card entry direction; when the sensing piece 7 does not move in the above two ways, it can be known that the card pushing assembly has failed.

[0076] While the specific embodiments of the present invention have been described in detail above, these are merely exemplary and the present invention is not limited thereto. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, any equivalent changes and modifications made without departing from the spirit and scope of the present invention are intended to be encompassed within the scope of the present invention.
