Description

Technical Field

[0001] This application relates to the technical field of bank self-service terminals, and in particular to a card swallowing retrieval device and a bank self-service terminal. Background Technology

[0002] Card readers are a crucial component of bank self-service terminals such as ATMs. They are used to read user information stored in magnetic stripe cards, IC cards, and other bank cards. During operation, card readers need to perform actions such as card insertion, card reading, and card retention. If a customer enters their PIN multiple times or makes an incorrect operation, the card reader will retain the card, which will then be transferred to the card slot within the bank's self-service terminal.

[0003] When a customer's card is swallowed by the bank, the customer needs to go to the bank counter to retrieve the card. Bank staff need to retrieve the card from the card box, register it, and confirm the information, which increases the workload of staff and reduces the efficiency of business processing. Summary of the Invention

[0004] To reduce the workload of bank staff after a card is swallowed, this application provides a card retrieval device and a bank self-service terminal.

[0005] Firstly, this application provides a card retrieval device, which adopts the following technical solution:

[0006] A card retrieval device includes a housing and a card box for storing swallowed cards. The card box is slidably installed inside the housing. The device also includes a verification module and a card return mechanism that returns the card after successful verification by the verification module. An installation block is fixed inside the housing. The installation block has a card return chamber for customers to retrieve cards. The card box has a first opening on the side near the installation block, and the installation block has a second opening on the side near the card box. When the first opening and the second opening are aligned, the card return mechanism delivers the card from the card box to the card return chamber.

[0007] By adopting the above technical solution, when a customer's card is swallowed, it will automatically enter the card box. At this time, the customer needs to verify the card through the verification module. After successful verification, the card ejection mechanism will perform the card ejection operation, causing the card box to slide inside the shell until the first opening and the second opening are aligned. The card ejection mechanism will then send the card from the card box to the card ejection room for the customer to pick up. There is no need to go to the bank staff to register and retrieve the card, thus reducing the workload of the bank staff.

[0008] Optionally, the card ejection mechanism includes a rotating plate rotatably installed inside the card box. The end of the rotating plate near the first opening is rotatably connected to the bottom surface of the card box. A connecting rope is fixedly connected to the end of the rotating plate away from the first opening. A hinge seat is fixedly installed on the side wall of the card box away from the mounting block. A rope winding roller is rotatably installed on the hinge seat. The rope winding roller is fixedly connected to the end of the connecting rope away from the rotating plate. A first connecting rod is also rotatably connected to the hinge seat. A second connecting rod is rotatably connected to the end of the first connecting rod away from the card box. A fixing block is provided below the card box. The end of the second connecting rod away from the first connecting rod is rotatably connected to the fixing block. The rotation axes of the first and second connecting rods are parallel. A cylinder is fixedly installed on the fixing block. The output end of the cylinder is fixedly connected to the hinge seat.

[0009] By adopting the above technical solution, when the card ejection mechanism performs the card ejection operation, the output end of the cylinder retracts, causing the card box to slide vertically until the first opening and the second opening are aligned, and the first connecting rod and the second connecting rod approach each other, causing the rope winding roller coaxial with the first connecting rod to rotate, and the connecting rope is wound on the rope winding roller, thereby causing the rotating plate to tilt inside the card box, promoting the card to slide from the card box into the card ejection chamber.

[0010] Optionally, a fixed pulley is fixed to the top of the side wall of the card box near the rope winding roller, and the connecting rope is looped on the fixed pulley.

[0011] By adopting the above technical solution, the fixed pulley further reduces the friction when the connecting rope is wrapped by the rope winding roller, thus reducing the possibility of the connecting rope breaking.

[0012] Optionally, the mounting block is provided with a card ejection port, which is located on the side of the card ejection chamber away from the second opening. A card ejection door is rotatably connected to the card ejection port, and the card ejection door can be rotated and opened in the vertical direction.

[0013] By adopting the above technical solution, in order to reduce the situation where cards slip from the card box into the card return chamber and fall out of the card return port due to inertia, the card return door can block the cards. Customers can open the card return door by turning it and then take out the returned cards, reducing the situation where cards are lost due to unnecessary drops.

[0014] Optionally, a handle is fixed to the side of the card ejection door away from the card ejection chamber.

[0015] By adopting the above technical solution, the handle makes it easier for customers to pull open the card return door to retrieve their cards.

[0016] Optionally, the card ejection door is made of a transparent material.

[0017] By adopting the above technical solution, the transparent plate allows customers to easily observe the cards falling in the card ejection chamber, ensuring that the ejection plate effectively blocks falling cards while also making it convenient for customers to retrieve their cards.

[0018] Optionally, the housing is further provided with a locking mechanism to lock the card ejection door at the card ejection opening. The locking mechanism includes a cavity formed in the bottom wall of the housing and a moving rod located in the cavity. The bottom wall of the housing is also provided with a through groove, which connects the card ejection chamber and the cavity. Multiple springs are fixed on the side of the moving rod away from the through groove. The multiple springs are spaced apart along the length of the moving rod. A first locking rod is fixed on the moving rod. The first locking rod is slidably connected to the through groove, and the first locking rod extends out of the through groove under the action of the springs. A second locking rod is fixed on the side of the card ejection door near the cavity. A clamping block is fixed on the side of the second locking rod near the first locking rod. The clamping block is located at the end of the second locking rod away from the card ejection door. When the first locking rod and the second locking rod abut against each other, the card ejection door is locked at the card ejection opening.

[0019] By adopting the above technical solution, the locking mechanism ensures the security of the cards in the card box. The locking mechanism will only open after the card return mechanism returns the card after successful identity verification, making it convenient for customers to take the card.

[0020] Optionally, the card box is fixed with an abutment rod on the side near the fixing block, and the fixing block is provided with a slot on the side near the card box. The slot is connected to the cavity, the abutment rod is slidably connected to the slot, and the side of the abutment rod away from the card box can abut against the moving rod.

[0021] By adopting the above technical solution, when the card box slides to the upper side of the fixed block and the first opening is aligned with the second opening, the abutting rod extends into the cavity and abuts against the moving rod, causing the moving rod to slide away from the through groove, causing the first card rod to retract into the through groove. At this time, the card ejection door can be rotated to open and the card can be retrieved.

[0022] Optionally, the end of the clamping block away from the second clamping rod has an inclined surface that slopes towards the side away from the ejector gate and towards the second clamping rod.

[0023] By adopting the above technical solution, the inclined surface on the clamping block further facilitates the clamping block to slide past the first clamping rod, and clamps the first clamping rod between the clamping block and the ejector gate.

[0024] Secondly, this application provides a bank self-service terminal, which adopts the following technical solution:

[0025] A bank self-service terminal includes the card retrieval device described in any one of the above claims.

[0026] By adopting the above technical solution, after the card is swallowed, it is sent to the card box. The card retrieval device automatically verifies the customer's information and returns the card after successful verification. This eliminates the need for customers to go to the bank counter to complete complicated procedures, reducing the workload of bank staff.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When a customer's card is swallowed, it will automatically enter the card box. At this time, the customer needs to verify the card through the verification module. After successful verification, the card ejection mechanism will perform the card ejection operation, causing the card box to slide inside the shell until the first opening and the second opening are aligned. The card ejection mechanism will then send the card from the card box to the card ejection room for the customer to pick up. There is no need to go to the bank staff to register and retrieve the card, which reduces the workload of the bank staff.

[0029] 2. To reduce the chance of cards slipping from the card box into the card return chamber and falling out of the return slot due to inertia, the card return door can block the cards. Customers can open the return door by turning it and then take out the returned cards, reducing the chance of cards being lost due to unnecessary drops.

[0030] 3. The locking mechanism ensures the security of the cards in the card box. The locking mechanism will only open after the card return mechanism has successfully returned the card, making it convenient for the customer to take the card. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a card-swallowing retrieval device and a bank self-service terminal.

[0038] Reference Figure 1 and Figure 2 The bank self-service terminal includes a card retrieval device for returning swallowed cards. The card retrieval device includes a housing 1, a card box 2 for temporarily storing swallowed cards is slidably installed inside the housing 1, and an installation block 11 is fixed inside the housing 1. The installation block 11 is located on one side of the card box 2, and a card ejection chamber 111 is opened inside the installation block 11 for customers to retrieve their cards. The card ejection chamber 111 is located on the lower side of the card box 2. The housing 1 also includes a verification module (not shown in the figure) and a card ejection mechanism 3. When a customer's card is swallowed, it can be verified independently through the verification module. After the verification module successfully verifies the customer's information, it transmits an electrical signal to the card ejection mechanism 3. The card ejection mechanism 3 causes the card in the card box 2 to enter the card ejection chamber 111, thereby enabling the customer to retrieve the swallowed card independently without having to go to the counter to handle the card retrieval business, reducing the workload of bank staff.

[0039] The verification module includes a photo-taking module (not shown in the figure) and a processing module (not shown in the figure). The photo-taking module and the processing module are electrically connected. The photo-taking module is located above the card box 2 and can take pictures of cards that fall into the card box 2. The processing module obtains the card number based on the image and transmits the card number to the bank's self-service terminal system. After the customer's card is swallowed, the customer actively initiates a card retrieval operation on the bank's self-service terminal and enters the card number of the swallowed card on the bank's self-service terminal. If the entered card number matches the card number recognized by the processing module, the verification is successful and the card can be ejected. The card ejection mechanism 3 receives an electrical signal to eject the card.

[0040] Reference Figure 2 and Figure 3 The card ejection mechanism 3 includes a fixing block 31 fixed inside the housing 1. The fixing block 31 is located directly below the card box 2. The card ejection chamber 111 is located on one side of the fixing block 31. The card box 2 has a first opening 21 for the card to pass through on the side near the card ejection chamber 111. The mounting block 11 has a second opening 112 for the card to pass through on the side near the card box 2. The mounting block 11 has a card ejection port 113 for a person to take out the card on the side away from the second opening 112. When the bottom wall of the card box 2 is attached to the fixing block 31, the first opening 21 and the second opening 112 are aligned and connected.

[0041] Reference Figure 2The card ejection mechanism 3 also includes a rotating plate 32 rotatably mounted on the bottom wall of the card box 2. The side of the rotating plate 32 near the first opening 21 is rotatably connected to the bottom wall of the card box 2. The rotating plate 32 can be horizontally set inside the card box 2. When the first opening 21 and the second opening 112 are connected, the rotating plate 32 is tilted upward from the direction near the first opening 21 to the direction away from the first opening 21, so that the card on the rotating plate 32 automatically falls into the card ejection chamber 111 along the inclined surface of the rotating plate 32, thereby making it convenient for the customer to take out the card from the card ejection port 113.

[0042] A connecting rope 33 is fixed to the end of the rotating plate 32 away from the first opening 21. A hinge seat 34 is fixed to the outer side wall of the card box 2 away from the mounting block 11. A connecting shaft 35 is rotatably mounted on the hinge seat 34. The axis of the connecting shaft 35 is parallel to the axis of rotation of the rotating plate 32. A rope winding roller 36 is coaxially fixed on the connecting shaft 35. The connecting rope 33 passes around the upper edge of the card box 2, and the end of the connecting rope 33 away from the rotating plate 32 is fixedly connected to the rope winding roller 36. The connecting rope 33 can be wound on the rope winding roller 36.

[0043] A fixed pulley 37 is also fixed to the upper edge of the card box 2 away from the mounting block 11. The connecting rope 33 is looped on the fixed pulley 37 to reduce the possibility of the connecting rope 33 slipping on the upper edge of the card box 2 and breaking.

[0044] A first connecting rod 38 is fixed to one end of the connecting shaft 35 extending out of the hinge seat 34. The first connecting rod 38 is perpendicular to the axis of the connecting shaft 35, so that the first connecting rod 38 is rotatably mounted on the hinge seat 34. A second connecting rod 39 is rotatably connected to the end of the first connecting rod 38 away from the connecting shaft 35. The axis of rotation of the second connecting rod 39 is parallel to the axis of rotation of the first connecting rod 38. The end of the second connecting rod 39 away from the first connecting rod 38 is rotatably connected to the fixing block 31. A fixing seat 311 is fixed on the fixing block 31. The second connecting rod 39 is rotatably connected to the fixing block 31 through the fixing seat 311. A vertically arranged cylinder 312 is also fixed to the side wall of the fixing block 31. The output end of the cylinder 312 is fixedly connected to the hinge seat 34. The extension and retraction of the output end of the cylinder 312 can realize the sliding of the card box 2 up and down in the housing 1.

[0045] The card ejection mechanism 3 also includes a control host (not shown in the figure) electrically connected to the cylinder 312. When the customer information is successfully verified, the control host controls the output end of the cylinder 312 to retract, causing the card box 2 to slide downward until the first opening 21 and the second opening 112 are opposite each other. During the sliding of the card box 2, the first connecting rod 38 and the second connecting rod 39 approach each other, and the first connecting rod 38 drives the connecting shaft 35 to rotate, causing the rope roller 36 to rotate, thereby causing the connecting rope 33 to wind around the rope roller 36, and then causing the connecting rope 33 to lift one end of the rotating plate 32, so that the rotating plate 32 is in an inclined state in the card box 2, so that the card can automatically enter the card ejection chamber 111 along the inclined surface of the rotating plate 32, making it convenient for the user to retrieve the card.

[0046] A sensor (not shown in the figure) is also fixed at the first opening 21. The sensor is electrically connected to the control host. When the sensor senses that a card in the card box 2 has slid out from the first opening 21, the sensor transmits an electrical signal to the control host. The control host controls the output end of the cylinder 312 to extend, so that the card box 2 is away from the fixed block 31, and the first opening 21 and the second opening 112 are in a staggered state, so that the card box 2 can continue to be used to receive swallowed cards.

[0047] Reference Figure 3 and Figure 4 To reduce the chance of cards falling from the card box 2 into the card return chamber 111 and then falling out of the card return port 113 due to inertia, a card return door 114 is also installed at the card return port 113. When the card return door 114 is set vertically, it can block the card return port 113. The card return door 114 is a transparent plate, which makes it convenient for customers to observe the card falling in the card return chamber 111.

[0048] The upper end of the card ejection door 114 is rotatably connected to the mounting block 11, so that the card ejection door 114 can be rotated and opened in the vertical direction away from the card ejection port 113. A handle 1141 is fixed on the side of the card ejection door 114 away from the card ejection port 113, and the customer can rotate and open the card ejection door 114 through the handle 1141.

[0049] To further ensure the security of cards when they are temporarily stored in card box 2, the housing 1 is also provided with a locking mechanism 4 to lock the card ejection door 114 to the card ejection port 113. The locking mechanism 4 includes a moving rod 41 and a first locking rod 42 perpendicular to the moving rod 41. A horizontally arranged cavity 115 is opened in the bottom wall of the housing 1. The cavity 115 is located below the card ejection chamber 111. The moving rod 41 is horizontally arranged in the cavity 115. The bottom wall of the housing 1 is also provided with a vertically arranged through groove 116. The through groove 116 connects the card ejection chamber 111 and the cavity 115. The through groove 116 is located on the side near the card ejection port 113. The first locking rod 42 passes vertically through the through groove 116, and the end of the first locking rod 42 away from the moving rod 41 extends into the card ejection chamber 111.

[0050] A spring 43 is fixed on the side of the moving rod 41 away from the through groove 116. There are multiple springs 43, and the multiple springs 43 are spaced apart along the length direction of the moving rod 41. One end of the multiple springs 43 is fixed to the moving rod 41, and the other end is fixed to the bottom wall of the cavity 115. The springs 43 cause the moving rod 41 to move upward and cause the upper end of the first locking rod 42 to extend out of the through groove 116.

[0051] A second locking rod 44 is vertically fixed on the side of the ejector gate 114 near the cavity 115. A locking block 45 is fixed on the second locking rod 44. The locking block 45 is located at the end of the second locking rod 44 away from the ejector gate 114. The first locking rod 42 can abut between the locking block 45 and the ejector gate 114, and the upper end of the first locking rod 42 abuts against the second locking rod 44. At this time, the ejector gate 114 is locked at the ejector opening 113.

[0052] The end of the locking block 45 away from the second locking rod 44 has an inclined surface that is inclined towards the side away from the ejector gate 114 and close to the second locking rod 44. As the locking block 45 rotates with the ejector gate 114, the inclined surface on the locking block 45 first abuts against the upper end of the first locking rod 42, causing the first locking rod 42 to slide downward. When the second locking rod 44 is aligned with the through groove 116, the upper end of the first locking rod 42 abuts against the second locking rod 44 under the action of the spring 43. At this time, the first locking rod 42 is located between the locking block 45 and the ejector gate 114, achieving the locking effect.

[0053] A slot 313 is vertically provided on the fixed block 31, and the slot 313 is connected to the cavity 115. A connecting rod 22 is vertically fixed on the bottom surface of the card box 2. The connecting rod 22 is opposite to the slot 313 and is slidably connected to the slot 313. The end of the connecting rod 22 away from the card box 2 can extend into the cavity 115 and abut against the moving rod 41. When the card box 2 slides to the upper surface of the fixed block 31, the abutment rod 22 abuts against the moving rod 41, causing the moving rod 41 to slide downwards. The spring 43 is compressed, which in turn causes the first card lever 42 to retract into the through groove 116. At this time, the locking mechanism 4 is in the open state, and the customer can pull the handle 1141 to open the card ejection door 114 to retrieve the card. When the card box 2 slides away from the fixed block 31, the abutment rod 22 moves away from the moving rod 41. Under the action of the spring 43, the moving rod 41 extends the upper end of the first card lever 42 out of the through groove 116, locking it with the second card lever 44, ensuring that the card ejection door 114 is locked at the card ejection opening 113.

[0054] The implementation principle of a card-swallowing retrieval device and a bank self-service terminal is as follows:

[0055] When the card box 2 is located on the upper side of the housing 1, it is used to receive the swallowed cards. After the verification module successfully verifies the cards, the card ejection mechanism 3 performs the card ejection operation. After receiving the electrical signal from the verification module, the output end of the cylinder 312 retracts, causing the card box 2 to slide downwards until the first opening 21 and the second opening 112 are connected. During the movement of the card box 2, the rotating plate 32 inside the card box 2 rotates, changing from a horizontal state to an inclined state. Finally, the rotating plate 32 tilts from the direction close to the first opening 21 to the direction away from the first opening 21, causing the cards inside the card box 2 to also change from a horizontal state to an inclined state. Due to gravity, they slide down the inclined plane into the card ejection chamber 111, and the card ejection door... 114 blocks the card ejection port 113, reducing the risk of cards slipping from the ejection port 113 to the ground due to inertia and causing unnecessary loss. When the card box 2 moves to the upper side of the fixing block 31, the first card lever 42 moves away from the first card lever 42, making it convenient for customers to open the card ejection door 114 to retrieve the cards. When the sensor detects that a card has slid out from the first opening 21, it transmits an electrical signal to the cylinder 312. The output end of the cylinder 312 extends, causing the card box 2 to move upward, and the abutment force of the abutment rod 22 on the moving rod 41 disappears. The first card lever 42 extends out of the through slot 116 and abuts against the second card lever 44. The first card lever 42 is located between the clamping block 45 and the card ejection door 114, so that the card ejection door 114 is locked at the card ejection port 113.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
