Description

Technical Field

[0001] The present invention relates to a self-service machine, and in particular to a self-service industrial and commercial license making machine. Background Art

[0002] Government self-service machines are currently relatively mature and widely used devices. They mainly guide office workers to handle relevant business independently through pre-set permissions and boot programs. In industrial and commercial services, license issuance is one of the main services. Generally, after the materials are reviewed and qualified, only the license needs to be printed and issued. At present, the license issuance still adopts manual operation. The main reason is that when receiving the license, proof materials such as receipts and issuance notices need to be received, and these materials can only be reviewed at the manual window at present. However, with the maturity of current image recognition and character recognition technologies, these reviews can be fully realized through self-service machines. Therefore, the applicant has designed a self-service industrial and commercial license making machine, which can issue licenses independently, thereby reducing the pressure on window staff and improving the license issuance efficiency.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0035] Refer to Figures 1 - 7 , a self-service industrial and commercial license making machine, including a housing 110 and a front door 120. One side of the front door 120 is hinged to the housing 110 through a hinge, and the other side is assembled with the housing 110 in an openable and closable manner through a door lock; the front door 120 closes the bottom of the housing 110, and a taking port 121 is provided on the front door 120. When in use, the license is output to the taking port 121, and the user takes the license from the taking port 121.

[0036] A touch screen 210, a card reader 220, a keyboard 230, a document camera 240, a printer 250, and a paper tray 260 are respectively installed on the housing 110. The touch screen 210 is used to display images and input information by touch; the card reader 220 is used to read IC cards and identity cards; the keyboard 230 is used to input information by pressing keys; the document camera 240 is used to capture images inside the shooting shell 111, mainly for capturing paper documents, identity cards, business licenses, etc. that need to be provided. The document camera 240 is installed above the shooting shell 111; the printer 250 is used to print licenses; the paper tray 260 is used to store blank licenses to be printed and supply paper to the printer 250. A camera 201 and a speaker 202 are respectively installed above the touch screen 210 on the housing 110. The camera 201 is used to collect images, and the speaker 202 is used to play sounds.

[0037] A paper receiving board 310 is installed at the paper outlet of the printer 250. The paper receiving board 310 is directly opposite to the taking port 121. The printed license is sent onto the paper receiving board, and the operator reaches into the taking port to take out the license.

[0038] During use, the operator approaches the housing and inputs request information through the keyboard or the touch screen. The system prompts the operator to place the identity card (or IC card) on the card reader 220 to read the identity card according to the built-in program. The camera captures the operator's head image for face recognition, and at the same time, the speaker 202 emits guiding prompt sounds according to the preset program. If there are documents that need to be scanned, the operator is prompted to put them into the shooting shell 111 one by one. After being captured one by one by the document camera 240, the images are sent to the image processing software for image processing and character recognition to identify the document information and the authenticity of the documents. After the identity authentication and the proof document authentication are passed, the system releases the license issuance permission according to the preset program, and then controls the printer 250 to take paper from the paper tray 260 for license printing; the printed license is sent onto the paper receiving board 310, and the operator reaches into the taking port 121, grabs the license, and takes it out. This embodiment can be applied to common government license services, such as business licenses, franchise licenses, industry permits, professional qualification certificates, etc. After obtaining the materials, they can be reviewed according to the review logic preset by the system or handed over to the back-end staff for online review.

[0039] See Figures 8 - 13 , because Figures 1 - 7 the design requires reaching into the taking port 121 to take the license. On the one hand, it is not easy to prompt the user, so it is easy for the user to forget to take it; on the other hand, when taking it, if the operation is improper, the license will be scratched against the inner wall and the inside of the taking port, resulting in damage or tearing of the license; at the same time, this design makes many operators habitually bend down to observe the taking port with their eyes, which is very inconvenient in use and easy to cause misunderstandings about government services. Therefore, the following improvements can be made to this embodiment:

[0040] The paper receiving board 310 is designed to be able to pass through and be taken out at 121, and this function is integrated into the paper receiving board mechanism. Guide seats 311 and a second rack 520 are respectively installed on the end surface of the paper receiving board 310 that faces away from contact with the license. A guide hole 3111 is provided in the guide seat 311. A first limiting ring 3112 is provided at one end of the guide hole 3111 that is far away from the taking port 121. The guide hole 3111 is engaged with and axially slidably assembled with a first sliding ring 422. The first sliding ring 422 is sleeved on one end of a guide cylinder 420. The other end of the guide cylinder 420 passes through the first limiting ring 3112 and is axially slidably assembled with it; a guide inner cylinder 421 is provided in the guide cylinder 420. A second limiting ring 423 is installed at one end of the guide inner cylinder 421 that is far away from the taking port, and the guide inner cylinder 421 is engaged with and axially slidably assembled with a second sliding ring 411. The second sliding ring 411 is installed on one end of a guide shaft 410. The other end of the guide shaft 410 passes through the second limiting ring 423 and is assembled with a bracket 330. The bracket 330 is installed in the housing; the guide shaft 410 is axially slidably assembled with the second limiting ring 423; the first sliding ring 422 cannot pass through the first limiting ring 3112, and the second sliding ring 411 cannot pass through the second limiting ring 423. When the paper receiving board 310 moves, it will first cause an axial displacement between the guide cylinder and the guide seat 311, thereby providing guidance for the movement of the paper receiving board 310. After the first sliding ring 422 is pressed against the first limiting ring 3112, the guide cylinder and the guide shaft will directly axially slide relative to each other, thereby continuing to provide guidance and support for the movement of the paper receiving board until the second sliding ring 411 is pressed against the second limiting ring 423 to reach the maximum displacement point. This design provides effective guidance for the movement of the paper receiving board, so that during use, the paper receiving board can shuttle through the taking port directionally to send out the license and then reset. During use, the operator can manually pull out the paper receiving board to take the license.

[0041] Preferably, the second rack 520 is in meshing transmission with a gear 530. The gear 530 is sleeved on a motor shaft 281. The motor shaft 281 passes through a support plate 311 and is inserted into a motor 280. The support plate 311 is installed on the bracket 330. After the motor is started, it can drive the gear to rotate circumferentially, thereby driving the paper receiving board to shuttle through the taking port 121.

[0042] More preferably, since a single second rack 520 cannot enable the paper receiving board 310 to have a sufficient displacement amount, after the paper receiving board extends to the maximum displacement towards the taking port, the license may still be partially located inside the taking port, thus greatly weakening the convenience effect of this case. For this, the following improvements are made in this embodiment:

[0043] The first rack 510 and the switch platform 320 are respectively installed on both sides of the support plate 331 where the second rack 520 is located. First sliding grooves 511 and second sliding grooves 512 are respectively arranged on both sides of the first rack 510. The two ends of the first sliding grooves 511 and the second sliding grooves 512 are closed. The first sliding grooves 511 and the second sliding grooves 512 are respectively engaged and slidably assembled with a first slider 521 and a second slider 3311. The first slider 521 is installed on the second rack 520, and the second slider 3311 is installed on the support plate 331. The teeth on the first rack 510 and the second rack 520 can both be engaged with the gear 530 for transmission.

[0044] In the initial state ( Figure 10 state), the teeth of the first rack 510 are not engaged with the gear, and the teeth of the second rack are engaged with the gear. When the gear rotates, it first drives the second rack (the paper receiving board) to move towards the taking port until the first slider 521 is tightly attached to the inner wall of the end of the first sliding groove 511 closest to the taking port. Then the second rack 520 drives the first rack 510 to move, so that the teeth of the first rack 510 are engaged with the gear. At this time, the gear 530 is simultaneously engaged with the first rack and the second rack to continue driving the paper receiving board to move outwards until the inner side of the end of the second sliding groove 512 farthest from the taking port is tightly attached to the second slider 3311, and the maximum displacement can be achieved. When the paper receiving board 310 needs to be retracted, reverse the gear, and the gear drives the first rack to reset, and the first rack drives the second rack to reset.

[0045] The above design also has the problem that the paper receiving board can be manually pushed to move relatively after the second rack and the gear are separated. Once the paper receiving board is blocked after the second rack and the gear are separated, the movement of the first rack will have no effect at all, and it will also affect the normal contraction of the paper receiving board. Therefore, the present embodiment also adds an interlock assembly. The interlock assembly includes a switch platform 320. A switch bar 540 is installed on the switch platform 320. The end face of the switch bar 540 is closer to the second rack 520 than the end face of the switch platform 320. A rack sliding groove 523 is arranged on the second rack 520. A lock block 650 is engaged and slidably installed on the rack sliding groove 523. The lock block 650 can be pressed against the side wall of the first rack, so that the first rack and the second rack are clamped together. The lock block 650 is also assembled with one end of a lock shaft 610. The other end of the lock shaft 610 is sleeved with a first spring 710 and then installed in a lock cylinder hole 621 and assembled with a limit sliding ring 611. The limit sliding ring 611 can slide in the lock cylinder hole 621 and cannot penetrate out of the lock cylinder hole 621. The two ends of the first spring 710 are respectively pressed against the end faces of the lock block 650 and the lock cylinder 620.

[0046] The lock cylinder hole 621 is provided in the lock cylinder 620. The lock cylinder 620 is axially slidably assembled with the holding plate 522. The holding plate 522 is installed in the rack chute 523. The lock cylinder 620 passes through the second rack 520, and a ball seat 660 is installed at this end of the lock cylinder 620. The ball 640 is installed on the ball seat 660 in a spherically rolling and non-detachable manner through the ball cover 630, and the ball cover 630 is installed on the lock cylinder 620. A oil guiding hole 661 is provided on the ball seat 660. The oil guiding hole 661 communicates the ball 640 with the lock cylinder hole 621, and the lock cylinder hole 621 is filled with lubricating oil. During use, the lubricating oil is conveyed to the ball through the oil guiding hole, and the ball rolls to smear the lubricating oil, so as to reduce the rolling friction of the ball.

[0047] A force receiving ring 622 is installed on the part of the lock cylinder 620 between the holding plate 522 and the end face of the rack chute 523 away from the first rack. The force receiving ring 622 cannot pass through the second rack 540, and a second spring 720 is sleeved on the part of the lock cylinder 620 between the holding plate 522 and the force receiving ring 622. The second spring 720 is used to apply a thrust to the lock cylinder 620 away from the holding plate 522, so that in the initial state, the lock block is not pressed against the first rack, and at this time, the first rack and the second rack can slide relative to each other.

[0048] Preferably, a guiding surface 541 is further provided on the switch bar 540. The guiding surface 541 protrudes gradually towards the second rack from the end away from the taking port to the end close to the taking port. This design can effectively guide the ball to contact the end face of the switch bar 540.

[0049] When the gear drives the second rack (paper receiving board) to move towards the taking port, since the first rack is not engaged with the gear and there is no clamping between the first rack and the second rack, the second rack moves relative to the first rack. The second rack drives the ball to move towards the switch bar 540 until the ball gradually contacts the guiding surface 541. Then, as the ball presses against the end face of the switch bar 540, the lock cylinder moves towards the lock block, causing the lock cylinder to compress the first spring and the second spring to apply pressure to the lock block. The lock block presses tightly against the first rack. At this time, the first rack and the second rack are clamped, enabling the second rack to drive the first rack to move until the first rack engages with the gear; the gear engages with both the first rack and the second rack simultaneously to continue conveying the paper receiving board until the gear engages with the first rack and disengages from the second rack. At this time, the gear continues to drive the first rack to drive the paper receiving board to move outwards until the inner end face of the second sliding groove 512 abuts against the second slider 3311. At this time, the maximum displacement point is reached. In this embodiment, at this time, the paper receiving board is completely pushed out of the taking port, and the operator can conveniently take the license. Then the motor reverses, driving the first rack and the second rack to reset until the ball disengages from the switch bar and the lock block is no longer clamped with the first rack, and the gear drives the second rack to reset. This design is mainly because the thickness of the entire device is limited, and the width at the paper receiving board is even more limited. Therefore, through this linkage design, the displacement of the paper receiving board is increased, and the clamping of the first rack and the second rack can also increase the rigidity when the paper receiving board moves out, forming a supporting effect to prevent the paper receiving board from deforming and being unable to reset. Additionally, this design is also a safety design to prevent injury. Because once the paper receiving board encounters an obstacle, it will slip between the first rack and the lock plate to prevent the paper receiving board from continuing to move out, preventing the paper receiving board from hurting people and also reminding the user.

[0050] Preferably, an anti - detachment flange 312 is installed at one end of the paper receiving board 310 away from the taking port 121. The anti - detachment flange 312 is used to prevent the license from sliding reversely due to inertia when the paper receiving board 310 moves towards the taking port, causing the license to fall off or not be output synchronously with the paper receiving board.

[0051] More preferably, a collision switch 270 is installed on the bracket 330 corresponding to the anti - detachment flange 312. The triggering end of the collision switch 270 faces the anti - detachment flange 312. When the paper receiving board resets, it can trigger the collision switch, enabling the collision switch to input a signal to the PLC. At this time, it is determined that the paper receiving board has been reset in place, and the motor is stopped accordingly.

[0052] Those parts not detailed in the present invention are all well - known techniques in the art.

[0053] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
