[0002] With the rapid development of automatic business in the service industry and the financial industry, the use of automatic card receiving and issuing machines has provided convenience for people to handle business by themselves. When issuing cards, the automatic card receiving and issuing machine generally needs to make the same blank card or white card, and then automatically issue the card after the card making is completed. However, whether the automatic card receiving and issuing machine is receiving or issuing a card, it is necessary to detect and verify the card surface pattern and information to avoid incomplete or blurred printing of the pattern or information.

[0055] See also Figure 2 and Figure 3 As shown, the angles at the connection between the side support plates 1 on both sides and 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 an incomplete card image.

[0056] 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.

[0057] The driving wheel is arranged below the driven wheel, and the distance between the wheel surfaces of the card picking wheel 2 of the driving wheel and the card picking wheel 2 of the driven wheel is less than the thickness of the card. A card picking wheel 2 for frictionally transmitting the card is fixedly arranged in the middle of the transmission shaft of the driving wheel and the driven wheel. The card enters the gap between the card picking wheel 2 of the driving wheel and the driven wheel at the card inlet, and the two rotating card picking wheels 2 clamp the card, and use friction to drive the card to move in the rotation direction of the card picking wheel 2 of the driving wheel, that is, push the card into the card output detection device to shoot and detect the graphic information on the surface of the card, and perform verification and verification.

[0058] The card pusher assembly includes a card carrier 3 and a pusher head 31. The pusher head 31 is fixedly mounted at both ends of the card carrier 3. The card carrier 3 is spaced and aligned with the driving wheel and the driven wheel. That is, when a card enters from the card inlet, a part of the card is clamped between the driving wheel and the driven wheel, and a part falls on the card carrier. At this time, the card is placed horizontally.

[0059] The length of the card pusher assembly is less than the distance between the card inlet and the card outlet.

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 push 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 includes a pushing rod, a screw and a driving motor 10. One end of the pushing rod is fixedly connected to the card supporting platform 3, and the other end of the pushing rod is provided with a screw ring. The screw ring is sleeved on the screw, and the screw is fixedly connected to the bottom support plate. One end of the screw is connected to the driving motor 10. When started, the driving motor 10 drives the screw to rotate, and the screw ring drives the screw ring to move toward the end of the screw under the rotation of the screw, that is, drives the card pushing assembly to reciprocate. The card pushing assembly transmits it to the card inlet through its power mechanism, 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 from the card inlet through the baffle 6 and the pressed push head 31 to the card supporting platform 3, and the card 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 state and blocks the card. Driven by the power mechanism, the card moves to the card outlet together with the card supporting platform 3.

[0062] The detection assembly includes an optical coupler detector, the height of the optical coupler detector 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 detector is fixedly arranged at the card inlet and the card outlet, used to detect the entry and exit of the card, and is arranged in the middle of one of the side support plates 1, used to detect the start of the card push assembly. The number of optical coupler detectors arranged in the middle of the side support plate 1 is two, and the distance between the card inlet and the optical coupler detector near the card inlet is equal to the distance between the optical coupler detector near the card outlet and the card outlet and is equal to the length of the card. The card push assembly also includes a sensor sheet 7, which is fixedly arranged on the side edge of the card carrier 3 near the side support plate 1; the detection assembly also includes a position sensor 42, which is fixedly arranged in the middle of the other side support plate 1 near the sensor sheet 7, used to detect the position of the card push assembly.

The number of the position sensors 42 is three, which are equidistantly arranged in the middle of the side support plate 1. In a preferred embodiment, when the card push assembly is activated, the induction sheet 7 moves with the card push assembly and passes through the position sensor 42, and the position sensor 42 receives the sensing information of the position of the card push assembly. The optical coupler detector is arranged at one end close to the baffle 6. When the optical coupler detector detects that a card has entered, the card push assembly is activated, the card push assembly moves to the card entrance, and the push head 31 of the card push assembly is pressed down by the baffle 6, the card is transmitted to the card push assembly by the card rubbing wheel 2, and the push head 31 of the card push assembly is lifted up and restored.

[0063] 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 bearing platform 3. The shooting component 5 is a camera.

[0064] The card output detection device further comprises an illumination mechanism 8, which is disposed on the top edge of the side support plates 1 on both sides. The illumination mechanism 8 is an LED fill light.

[0065] The card output 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.

[0066] The specific working principle of the card output detection device in the embodiment is as follows:

[0067] Initially, when the optical coupling detector at the card inlet of the card output detection device of this embodiment detects that a card has entered, the power synchronous pulley 9 and the power mechanism 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 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.

[0068] Next, the front end of the card passes through the baffle 6 and the first optical coupler detector 411 at the card inlet, passes through the push head 31 and enters the bearing area of ​​the card bearing platform 3, and then enters the friction transmission area between the active wheel and the driven wheel of the first card picking wheel 2 assembly. The card is clamped between the two card picking wheels 2. As the active wheel rotates, the card is driven to move toward the card outlet. At the same time, the driven wheel 2 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 coupling detector 412 again, the card output detection device starts the card pushing assembly again and drives it to move toward the card output port. 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 coupling detector 413 again, the card output detection device stops starting the card pushing assembly, so that the card is placed in the shooting detection area and pauses moving. The camera shoots the image and text on the entire surface of the card 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 to move toward the card output port. The pushing head 31 close to the card output port is pressed down by the blocking piece 6 at the card output port, and the card enters the friction transmission area between the active wheel of the second card rubbing wheel 2 assembly and the driven wheel of the card rubbing wheel 2. At this time, the card passes through the fourth optical coupling detector 414 to transmit the card out of the card output port, and the next card begins to enter the card output 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 entry port, and the card output detection device returns to its initial state.

[0069] 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 entry port to the card exit port; 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 entry port to the card exit port, 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 entry port to the card exit port; 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 exit port to the card entry port, that is, the card pushing device returns to the card entry port;

[0070] When the above-mentioned card pushing assembly transmits the card, when the sensing sheet 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 sensors 42 are used to detect the moving direction and state of the card pushing assembly. For example, when the sensing sheet 7 passes through the three position sensors 42 in the direction of the card exit in sequence, it can be known that the card pushing assembly is moving in the direction of the card exit; when the sensing sheet 7 passes through the three position sensors 42 in the direction of the card entry in sequence, it can be known that the card pushing assembly is moving in the direction of the card entry; when the sensing sheet 7 does not move in the above two ways, it can be known that the card pushing assembly has a fault.

[0071] The specific embodiments of the present invention are described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
