Description

Technical Field

[0001] The invention relates to the technical field of laser printing, and in particular to a laser printing system. Background Art

[0002] Cards are certificates and documents used to prove identity, experience, etc., such as ID cards, driver's licenses and other personal documents. Personalized information on ID cards, driver's licenses, passports, etc., such as portraits, names, ages, etc., need to be printed using a printer. The card to be printed generally includes two printing surfaces, namely the front printing surface and the back printing surface.

[0003] The laser printing system is a commonly used card printing device, which generally includes a control system and a printer table and a laser printing device that are communicatively connected to the control system, wherein: the printer table is used to carry the card to be printed, and the laser printing device prints the target printing information onto the current printing surface of the card to be printed according to the printing instructions issued by the control system.

[0004] In some printing practices, specific public template information is pre-printed on both the front and back printing surfaces of the card to be printed. The laser printing system needs to print out the printing information (i.e., personalized information) matching the public template information in the predetermined areas of the front and back printing surfaces of the card, and the public template information and the printing information constitute the complete card surface information after printing. Of course, the public template information and the printing information may include text and / or images.

[0005] Obviously, during the printing process, the type of the current printing surface of the card to be printed may be the front printing surface or the back printing surface, and the placement direction of the card to be printed may be the front printing surface or the back printing surface. Therefore, before printing the current printing surface of the card to be printed, the type and direction of the current printing surface of the card must be determined in advance, and then the printing information matching the public template information on the current printing surface can be printed on the current printing surface in the correct direction.

[0006] However, the laser printing system in the prior art cannot realize real-time recognition of the type and direction of the current printing surface of the card to be printed. Therefore, in order to ensure the accuracy of the printed information, before printing the card to be printed, the printing surface type and printing direction of the laser printing system are generally uniformly set, and then the printing surface type and direction of all the cards to be printed are uniformly adjusted to ensure that the state of each card to be printed is consistent with the settings of the printer. For example: when the laser printing system is set to positive printing surface and positive printing, all the cards to be printed are placed with the positive printing surface facing up, and all the cards to be printed are placed upright.

[0007] It can be seen that when using the laser printing system in the prior art to print cards, it is necessary to manually adjust the type and direction of the cards to be printed in advance, which is time-consuming, labor-intensive and inefficient.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Figure 1-16 A first embodiment of a laser printing system is shown, Figure 17-18 A second embodiment of the laser printing system is shown, and the first embodiment of the laser printing system is preferably introduced here.

[0045] 1. Introduction of laser printing system

[0046] In order to more clearly illustrate the technical problem to be solved by the first aspect of the present invention, we introduce the printing requirements of the cards to be printed in some specific printing scenarios by way of examples. Fig.14 As shown, it shows four possible states of the current printing surface of a card to be printed, where:

[0047] Fig.14 The a in the figure shows that the current printing side of the card to be printed is the positive printing side and the direction is upright.

[0048] Fig.14 The b in the figure shows that the current printing side of the card to be printed is the positive printing side and the direction is inverted.

[0049] Fig.14 The c in the figure shows that the current printing side of the card to be printed is the reverse printing side and the direction is upright.

[0050] Fig.14 The d in the figure shows that the current printing side of the card to be printed is the reverse printing side and the direction is inverted.

[0051] like Fig.14 As shown in a and b in FIG, the front printing surface of the card to be printed is pre-printed with public template information such as "name", "gender", "nationality", "ID card", and "address". Fig.14 As shown in c and d in FIG, the reverse printing surface of the card to be printed is pre-printed with public template information of "valid until 2028-05-01".

[0052] The laser printing system needs to print out the printing information that matches the public information in the specific area of ​​the front and back printing surfaces of the card to be printed (as shown in the dotted box in the figure). Of course, for the above four different states of the current printing surface, the printing information that matches it must be selected and printed in the corresponding printing direction. Please refer to Fig.16 As stated, Fig.16 a, b, c, and d in the figure show the Fig.14 Qualified printing effects of four different types and printing surfaces in different directions.

[0053] The laser printing system in the prior art cannot achieve real-time recognition of the type and direction of the current printing surface of the card to be printed. Therefore, in order to ensure the accuracy of the printed information, before printing the card to be printed, the printing surface type and printing direction of the laser printing system are generally set uniformly, and then the type and direction of the printing surface of all the cards to be printed are uniformly adjusted to ensure that the state of each card to be printed is consistent with the settings of the laser printing system. For example: when the laser printing system is set to positive printing surface and positive printing, all the cards to be printed are placed with the positive printing surface facing up, and all the cards to be printed are placed upright. It can be seen that when using the laser printing system in the prior art for printing, it is necessary to manually adjust the type and direction of the cards to be printed in advance.

[0054] In view of the above technical defects of the laser printing system in the prior art, the first aspect of the present invention provides a laser printing system, which can realize real-time and automatic recognition of the type and direction of the current printing surface of the card to be printed. Therefore, when using the laser printing system provided by the first aspect of the present invention to print the card, it is not necessary to uniformly adjust the type and direction of the card to be printed in advance, that is, it can complete the continuous printing of the two printing surfaces of the card to be printed in sequence. For the convenience of description, we define the printing surface to be printed first as the first printing surface, and the printing surface to be printed later as the second printing surface according to the order of printing. That is to say, the laser printing system provided by the first aspect of the present invention can complete the continuous printing of the first printing surface and the second printing surface of the card in sequence when printing the card.

[0055] Of course, the type of the first printing surface can be a front printing surface or a back printing surface, and the second printing surface is another printing surface of the opposite type to the first printing surface.

[0056] Please refer to Figures 1 to 5 , Figures 1 to 5 The schematic structural diagram of the first embodiment of the laser printing system provided by the first aspect of the present invention is shown from different perspectives. Figures 1 to 5 As shown, the laser printing system includes a printer station 30, a laser printing device 60, and a control system 70. The printer station 30 and the laser printing device 60 are respectively connected to the control system 70 for communication.

[0057] The printer platform 30 includes a translation mechanism and a flipping mechanism. The translation mechanism is used to drive the card to translate to reach or leave a predetermined printing position. The flipping mechanism is used to flip the card to flip the current printing surface of the card from the first printing surface to the second printing surface.

[0058] The current printing surface is the printing surface of the card exposed to the laser printing device 60. The predetermined printing position is located on the printer table 30. When the card is translated to the predetermined printing position, the laser printing device 60 can print the current printing surface of the card. The flipping method of the flipping mechanism is a front-to-back flipping method or a left-to-right flipping method, wherein:

[0059] The front-to-back flipping method is that the flipping mechanism flips the current printing surface of the card from the first printing surface to the second printing surface in a translation direction parallel to the card. After the front-to-back flipping, the type of the current printing surface changes, but the direction remains unchanged. Please refer to Fig.14 As shown, for example, if the first printed side of the card is currently Fig.14 a in (type is positive printing side, direction is upright), then after flipping back and forth, the current second printing side of the card is Fig.14 c in (type is reverse printing side, direction is upright).

[0060] The left-right flipping method is that the flipping mechanism flips the current printing surface of the card from the first printing surface to the second printing surface in a direction perpendicular to the translation direction of the card. After the left-right flipping, the type and direction of the current printing surface are changed. Fig.14 As shown, for example, if the first printed side of the card is currently Fig.14 a (type is positive printing side, direction is upright), after flipping left and right, the current second printing side of the card is Fig.14 d in (type is reverse printing side, direction is reverse).

[0061] The control system 70 can obtain the information to be printed. The control system 70 can also determine the type and direction of the current printing surface of the card and generate a printing information template matching the type and direction of the current printing surface based on the information to be printed, and send it to the laser printing device 60.

[0062] In some embodiments, after the control system 70 obtains the information to be printed, it immediately generates a printing information template set based on the information to be printed, and the printing information template set includes printing information templates that match the type and direction of the printing surface of the card one by one. Fig.14 As shown, as an exemplary description, for Fig.14 The card to be printed includes the following information: Fig.15 The identity information in the dashed box of a and Fig.15 The printing information template includes four printing information templates that match the type and direction of the printing surface of the card, respectively. Fig.15 a in Fig.15 b in Fig.15 c and Fig.15 The print information template shown in d in the figure. Fig.15 The print information template shown in a is the same as Fig.14 The printing surface shown in a in the figure (type is positive printing surface, direction is upright); Fig.15 The print information template shown in b is the same as Fig.14 The printed surface shown in b in FIG. 1 (the type is the positive printed surface, and the direction is reversed); Fig.15 The print information template shown in c is the same as Fig.14 The printed surface shown in c in FIG. 1 (the type is the reverse printed surface, and the direction is the normal surface) matches; Fig.15 The print information template shown in d is the same as Fig.14 The printed surface shown in d in the figure (type is reverse printed surface, direction is reversed) matches the printed surface shown in d in the figure.

[0063] In these embodiments, after the control system 70 determines the type and direction of the current printing surface, it then selects a matching printing information template from the pre-generated printing information template set according to the type and direction of the current printing surface and sends it to the laser printing device 60. For example, the current printing surface of the card is Fig.14 When the printing surface shown in a in FIG. 1 is displayed, the control system 70 will Fig.15 The printing information template shown in a in FIG. 1 is sent to the laser printing device 60. The laser printing device 60 prints the text and / or pattern corresponding to the printing information template on the current printing surface of the card.

[0064] In some other embodiments, the control system 70 only stores the information to be printed after acquiring it, and does not generate a printing information template set. In these embodiments, after the control system 70 determines the type and direction of the current printing surface, it generates a printing information template that matches the type and direction of the current printing surface based on the information to be printed and sends it to the laser printing device 60.

[0065] The laser printing device 60 includes a laser light source (not shown) and a scanning galvanometer 601, wherein the scanning galvanometer 601 can focus the light path of the laser light source to form a laser focus spot, and can control the laser focus spot to scan at high speed on the printer table 30, thereby realizing laser printing on the current printing surface of the card to be printed carried on the printer table 30.

[0066] Please refer again Figures 14 to 16 As described above, for four different printing surfaces ( Fig.14 a to d), the laser printing device 60 obtains corresponding different printing information templates ( Fig.15a to d) in the figure, and print the information of the print information template onto the print surface. The print result after printing is as follows: Fig.16 As shown in a to d.

[0067] How the control system obtains information to be printed

[0068] In some embodiments, the information to be printed is pre-stored in the card to be printed before printing. In these embodiments, the laser printing system provided by the present invention further includes a card reading and writing device 20 that is communicatively connected to the control system 70, and the card reading and writing device 20 is arranged on one side of the printer table 30. Before entering the printer table 30 to be printed, the card to be printed first enters the card reading and writing device 20, and the card reading and writing device 20 reads the information to be printed pre-stored in the card to be printed and sends the information to be printed to the control system 70, thereby enabling the control system 70 to obtain the information to be printed.

[0069] In some other embodiments, the control system 70 is connected to an external host computer for communication, and the information to be printed is generated by the host computer. Before printing, the host computer sends the information to be printed to the control system 70, thereby enabling the control system 70 to obtain the information to be printed.

[0070] Of course, the information to be printed can also be pre-stored in the control system 70 before printing. When printing, the control system 70 can directly retrieve the information to be printed.

[0071] How the control system determines the type and direction of the first print surface

[0072] The laser printing system of the present invention further comprises a camera device 50 disposed above the printer table 30, and the camera device 50 is communicatively connected with the control system 70. The camera device 50 comprises a camera for acquiring an image of a card.

[0073] Preferably, the camera device 50 further includes a light source, and the light emitted by the light source can be irradiated onto the printer table 30 to improve the imaging quality.

[0074] When the card to be printed reaches the predetermined printing position of the printer table 30, the camera device 50 obtains the image of the current first printing surface of the card and sends the image of the current first printing surface to the control system 70. The control system 70 recognizes the image of the first printing surface through image recognition technology to determine the type and direction of the first printing surface.

[0075] The image recognition technology is an existing technology well known to those skilled in the art, and this specification will not describe its specific implementation method and detailed process. For example, as an optional implementation method, the control system 70 pre-stores standard reference images of different types and different directions of the print surface of the card to be printed. The control system 70 compares the acquired image of the first print surface with each of the standard reference images one by one to determine the type and direction of the first print surface. Specifically:

[0076] Since the public template information is pre-printed on both printing surfaces of the card to be printed, in some embodiments, the control system 70 determines the type and direction of the first printing surface by identifying the public template information in the image of the first printing surface.

[0077] In order to reduce the difficulty of identification, in some other embodiments, corresponding printing surface identification marks are pre-printed on the two printing surfaces of the card to be printed. The control system 70 can determine the type and direction of the first printing surface only by identifying the printing surface identification marks on the first printing surface.

[0078] like Fig.14 As shown, a right angle mark with an opening upward is pre-printed at the lower right corner of the front printing surface of the card to be printed, and a right angle mark with an opening downward is pre-printed at the upper right left corner of the reverse printing surface of the card to be printed. By identifying the printing position and opening direction of the right angle mark on the current first printing surface, the type and direction of the current first printing surface can be identified.

[0079] How the control system determines the type and direction of the second print surface

[0080] After the printing of the current first printing surface of the card is completed, the flipping mechanism on the printer table 30 flips the card so that the current printing surface of the card is flipped to become the second printing surface.

[0081] In some embodiments, the control system determines the type and direction of the second print surface based on the type and direction of the first print surface and the predetermined flipping method. For example, when the control system 70 controls the flipping mechanism to flip the card forward and backward in a translation direction parallel to the card so as to flip the current print surface of the card from the first print surface to the second print surface. The control system 70 determines that the type of the current second print surface is opposite to the type of the first print surface, and the direction of the second print surface is the same as the direction of the first print surface. For another example, when the flipping mechanism flips the card left and right in a translation direction perpendicular to the card so as to flip the current print surface of the card from the first print surface to the second print surface. The control system 70 determines that the type of the current second print surface is opposite to the type of the first print surface, and the direction of the second print surface is opposite to the direction of the first print surface.

[0082] Of course, in some other embodiments, the type and direction of the second print surface can also be determined in the same way as the determination method of the first print surface. Specifically, when the flip mechanism flips the current first print surface to the second print surface, the camera device 50 obtains the image of the current second print surface of the card and sends the current image of the second print surface to the control system 70, and the control system 70 recognizes the image of the second print surface through image recognition technology to determine the type and direction of the second print surface.

[0083] Please refer to Figures 1 to 6 As shown, in some preferred embodiments, the laser printing system provided by the present invention further includes an automatic card issuing device 10 arranged on one side of the printer table 30 and an automatic card output device 40 arranged on the other side of the printer table 30 .

[0084] The automatic card issuing device 10 is used to store at least one card to be printed and transmit the cards to be printed one by one to the printer table 30 to achieve automatic card issuance. Of course, if the laser printing system includes the card reading and writing device 20, the card reading and writing device 20 is arranged between the automatic card issuing device 10 and the printer table 30. After the automatic card issuing device 10 issues a card, the card first passes through the card reading and writing device 20 and then enters the printer table 30.

[0085] The automatic card discharging device 40 is used to remove the printed card from the printer table 30 to achieve automatic card discharging.

[0086] Furthermore, a card collecting device 80 may be provided on one side of the automatic card dispensing device 40 , and the card collecting device 80 is used to collect and store the printed cards.

[0087] The structure and working principle of the laser printing system provided by the present invention have been described in detail above. In order to more clearly introduce the specific printing process of the laser printing system, the third part below will exemplarily describe the printing method of the laser printing system of the present invention.

[0088] 2. Introduction of laser printing system with galvanometer calibration function

[0089] As described above in the first aspect of the present invention, the laser printing system, wherein the laser printing device 60 includes a laser light source and a scanning galvanometer 601, wherein: the scanning galvanometer 601 can focus the light path of the laser light source to form a laser focus spot, and can control the laser focus spot to scan at high speed on the printer table 30, thereby realizing laser printing on the current printing surface of the card to be printed carried on the printer table 30.

[0090] During the printing process, if the scanning galvanometer 601 cannot move strictly along the predetermined trajectory due to a fault, the laser printing device 60 cannot achieve correct printing. In addition, if the scanning galvanometer 601 fails, the laser focus spot may stay in a specific area of ​​the card for a long time during the printing process, eventually causing the card to be burned or even causing a fire. Therefore, before printing the current printing surface of the card, it is necessary to calibrate the scanning galvanometer 601 to ensure that the scanning galvanometer 601 is in normal working condition.

[0091] In the prior art, in order to implement the pre-printing calibration of the scanning galvanometer 601 , it is generally necessary to install a special self-test system on the laser printing system, which increases the cost and system complexity of the laser printing system.

[0092] The second aspect of the present invention provides a laser printing system with a galvanometer calibration function. The structure and printing working principle of the laser printing system are basically the same as those of the laser printing system provided by the first aspect of the present invention. The structural feature is that the laser printing device 60 also includes an indicator light source, which can emit visible light, such as red light. In some embodiments, the indicator light source is a self-contained light source of the laser printing device 60, which is integrated with the laser light source. In other embodiments, the indicator light source is installed on one side of the laser light source and is installed close to the laser light source.

[0093] When the indicator light source is turned on, the scanning galvanometer 601 can focus the light path of the indicator light source to form an indicator light focus spot, and can control the indicator light focus spot to scan at high speed on the printer table 30 according to a predetermined trajectory to form a verification pattern. Of course, if the scanning galvanometer 601 is in a normal working state, the verification pattern should be consistent with the predetermined trajectory.

[0094] For example, the predetermined trajectory is a circle with a diameter of 2 cm. If the scanning galvanometer 601 is in a normal working state, the verification pattern should also be a circle with a diameter of 2 cm.

[0095] The camera device 50 can obtain the image of the verification pattern and send the image information to the control system 70. The control system 70 verifies the scanning galvanometer by analyzing the received image information. If the control system 70 believes that the working state of the scanning galvanometer 601 is abnormal, the control system 7 controls the laser printing device 60 to stop printing. If the control system 70 believes that the working state of the scanning galvanometer 601 is normal, the control system 7 controls the laser printing device 60 to start printing.

[0096] In some specific embodiments, the control system 70 analyzes the received image information through image recognition technology to implement calibration of the scanning galvanometer.

[0097] The image recognition technology is an existing technology well known to those skilled in the art, and this specification does not describe its specific implementation and detailed process. For example, as an optional implementation, the control system 70 pre-stores the desired verification image formed when the scanning galvanometer 601 moves along the predetermined trajectory in a normal working state.

[0098] For example, when the predetermined track is a circular track with a diameter of 2 cm, the expected verification image is a circle with a diameter of 2 cm.

[0099] The control system 70 compares the acquired verification pattern image with the expected verification image to determine whether the state of the scanning galvanometer is normal. Specifically:

[0100] When the image of the verification pattern is consistent with the expected verification image, the control system determines that the scanning galvanometer is in a normal working state.

[0101] When the image of the verification pattern is inconsistent with the expected verification image, the control system determines that the scanning galvanometer is in an abnormal working state.

[0102] 3. Introduction to the printing method of laser printing system

[0103] A third aspect of the present invention provides a printing method of a laser printing system, wherein the laser printing system is the laser printing system provided by the first aspect or the second aspect of the present invention introduced above.

[0104] like Figures 1 to 5 As shown, the laser printing system includes a printer station 30, a camera device 50, a laser printing device 60 and a control system 70, wherein the printer station 30, the laser printing device 60, the camera device 50 are respectively connected to the control system 70. The printing method of the laser printing system provided by the present invention can realize continuous printing of the first printing surface and the second printing surface of the card to be printed.

[0105] In one embodiment, the printing method of the laser printing system provided in the third aspect of the present invention includes:

[0106] Step 1: The control system 70 obtains the information to be printed and generates a printing information template set based on the information to be printed, wherein the printing information template set includes printing information templates that match the type and direction of the printing surface of the card one by one.

[0107] Please refer to Fig.14 and Fig.15 As shown, as an exemplary description, the information to be printed includes: Fig.15 The identity information in the dashed box of a and Fig.15 The printing information template includes four printing information templates that match the type and direction of the printing surface of the card, respectively. Fig.15 a in Fig.15 b in Fig.15 c and Fig.15 The print information template shown in d in the figure. Fig.15 The print information template shown in a is the same as Fig.14 The printing surface shown in a in the figure (type is positive printing surface, direction is upright); Fig.15 The print information template shown in b is the same as Fig.14 The printed surface shown in b in FIG. 1 (the type is the positive printed surface, and the direction is reversed); Fig.15 The print information template shown in c is the same as Fig.14 The printed surface shown in c in FIG. 1 (the type is the reverse printed surface, and the direction is the normal surface) matches; Fig.15 The print information template shown in d is the same as Fig.14 The printed surface shown in d in the figure (type is reverse printed surface, direction is reversed) matches the printed surface shown in d in the figure.

[0108] In some embodiments, the information to be printed is pre-stored in the card to be printed before printing. In these embodiments, the laser printing system further includes a card reading and writing device 20 that is communicatively connected to the control system 70, and the card reading and writing device 20 is disposed on one side of the printer table 30. Before entering the printer table 30 to be printed, the card to be printed first enters the card reading and writing device 20, and the card reading and writing device 20 reads the information to be printed pre-stored in the card to be printed and sends the information to be printed to the control system 70, thereby enabling the control system 70 to obtain the information to be printed.

[0109] In some other embodiments, the card to be printed is a blank card, in which no information is stored. In these embodiments, the control system 70 can be connected to an external host computer for communication, and the information to be printed is generated by the host computer. Before printing, the host computer sends the information to be printed to the control system 70, so that the control system 70 acquires the information to be printed. Of course, the information to be printed can also be directly imported into the control system 70 before printing. In these embodiments, before printing, the control system 70 sends the acquired information to be printed to the card reader / writer 20, and controls the card reader / writer 20 to write the information to be printed into the card.

[0110] Step 2: The translation mechanism of the printer table 30 translates the card to be printed to a predetermined printing position. When the card to be printed reaches the predetermined printing position, the camera device 50 obtains an image of the current first printing surface of the card and sends it to the control system 70.

[0111] In some embodiments, during the process of translating the card to be printed to the predetermined printing position by the translation mechanism of the printer table 30, the control system 70 determines whether the card has reached the predetermined printing position at predetermined intervals, and the translation mechanism stops translating when the card reaches the predetermined printing position. Specifically, the specific process of the control system 70 determining whether the card has reached the predetermined printing position is as follows: the camera device 50 obtains the image of the card to be printed and sends it to the control system 70, and the control system 70 analyzes the received image of the card to be printed by image recognition technology to determine whether the card to be printed has reached the predetermined printing position. The image recognition technology is a prior art well known to those skilled in the art, and the present specification does not describe its specific implementation and detailed process. For example, as an optional implementation, the control system 70 pre-stores a standard reference image of the card to be printed at the predetermined printing position, and the control system 70 can identify whether the card to be printed has reached the predetermined printing position by comparing the received image of the card to be printed with the standard reference image.

[0112] Step three: The control system 70 identifies the received image of the first printing surface to determine the type and orientation of the first printing surface, and selects a first printing information template that matches the type and orientation of the first printing surface from the printing information template set and sends it to the laser printing device 60. The laser printing device 60 prints a pattern and / or text corresponding to the first printing information template on the first printing surface.

[0113] In some embodiments, the control system 70 uses image recognition technology to recognize the type and direction of the first print surface. The image recognition technology is a prior art well known to those skilled in the art, and this specification does not describe its specific implementation and detailed process. For example, as an optional implementation, the control system 70 pre-stores standard reference images of print surfaces of different types and directions of the card to be printed, and the control system 70 compares the acquired image of the first print surface with each of the standard reference images one by one to determine the type and direction of the first print surface.

[0114] Since common template information is pre-printed on both printing surfaces of the card to be printed, in some embodiments, the control system 70 determines the type and direction of the first printing surface by identifying the common template information in the image of the first printing surface.

[0115] In some other embodiments, the two printing surfaces of the card to be printed are pre-printed with special printing surface identification marks. The control system 70 can determine the type and direction of the first printing surface only by identifying the printing surface identification marks in the image of the first printing surface. Fig.14 As shown, in some embodiments, a right angle mark with an opening upward is pre-printed at the lower right corner of the front printing surface of the card to be printed, and a right angle mark with an opening downward is pre-printed at the upper right left corner of the reverse printing surface of the card to be printed. By identifying the printing position and opening direction of the right angle mark on the current first printing surface, the type and direction of the current first printing surface can be identified.

[0116] In addition, in some preferred embodiments, after the first printing surface of the card is printed, a step of checking the printing effect of the first printing surface is also included. If the first printing surface is printed properly, the card is flipped to print the second printing surface. Otherwise, the control system 70 controls the translation mechanism of the printer table 30 to directly move the current card out of the printer table 30 as a waste card. Specifically, the checking step is as follows: the camera device 50 obtains the image of the first printing surface after printing and sends it to the control system 70; the control system 70 analyzes the received image of the first printing surface after printing through image recognition technology to determine whether the current first printing surface is printed properly. Similarly, the image recognition technology involved here is an existing technology well known to those skilled in the art, and this specification will not describe its specific implementation method and detailed process. For example, as an optional implementation method, the control system pre-stores a standard reference image of the first printing surface after correct printing, and the control system can identify whether the current first printing surface is printed properly by comparing the received image of the first printing surface after printing with the standard reference image.

[0117] Step 4: The flipping mechanism of the printer table 30 flips the card to flip the current printing surface of the card to the second printing surface. The control system 70 determines the type and direction of the second printing surface based on the type of the first printing surface and the flipping method of the flipping mechanism, and selects a second printing information template that matches the type and direction of the second printing surface from the printing information template set and sends it to the laser printing device 60. The laser printing device 60 prints a pattern and / or text corresponding to the second printing information template on the second printing surface.

[0118] In some embodiments, the flipping mechanism flips the card in a forward and backward flipping manner parallel to the translation direction of the card to flip the current printing surface of the card from the first printing surface to the second printing surface. In these embodiments, the control system 70 determines that the type of the current second printing surface is opposite to the type of the first printing surface, and the direction of the second printing surface is the same as the direction of the first printing surface.

[0119] In some other embodiments, the flipping mechanism flips the card in a left-right flipping manner perpendicular to the translation direction of the card to flip the current printing surface of the card from the first printing surface to the second printing surface. In these embodiments, the control system 70 determines that the type and direction of the current second printing surface are opposite to those of the first printing surface.

[0120] 4. Introduction of Automatic Card Issuing Device

[0121] The above only briefly introduces the automatic card issuing device 10. Figures 6 to 9 The specific structure of the automatic card issuing device 10 in some embodiments is shown in FIG. Fig. 9 The automatic card issuing device 10 is introduced in detail.

[0122] The fourth aspect of the present invention provides an automatic card issuing device 10, which can store at least one card to be printed and transmit the cards to be printed one by one to the printer station 30 to achieve automatic card issuance. The automatic card issuing device 10 includes a card issuing frame and a card issuing drive mechanism, wherein:

[0123] The card issuing frame includes a first card issuing side plate 101 and a second card issuing side plate 102 which are vertically and oppositely arranged, and a support plate 106 which is horizontally connected between the first card issuing side plate 101 and the second card issuing side plate 102, and a driving window 107 is formed on the support plate 106. The first card issuing side plate 101, the second card issuing side plate 102 and the support plate 106 constitute a card storage slot for storing at least one card to be printed.

[0124] The card issuing drive mechanism is used to move the cards to be printed in the card storage slot out of the card storage slot one by one to achieve automatic card issuing, and the card issuing drive mechanism includes a card issuing transmission wheel 108 and a card issuing gear transmission structure. The card issuing transmission wheel 108 is located below the card storage slot, and the card issuing transmission wheel 108 passes through the driving window 107 upward and is slightly higher than the upper surface of the support plate 106. The card issuing gear transmission structure is connected to the card issuing transmission wheel 108 and drives the card issuing transmission wheel 108 to rotate, so as to move the card to be printed located in the card storage slot and in contact with the support plate 106 out of the card storage slot.

[0125] In some embodiments, Figure 7 , Figure 8 As shown, the card issuing gear transmission structure includes a card issuing driving gear 103 and a card issuing driven gear 104 arranged on the first card issuing side plate 101, the card issuing driving gear 103 and the card issuing driven gear 104 are connected via a card issuing belt 105, and the card issuing transmission wheel 108 is connected to the card issuing driven gear 104 via a transmission shaft passing through the first card issuing side plate 101.

[0126] When the card issuing driving gear 103 rotates, it can drive the card issuing driven gear 104 to rotate to drive the card issuing transmission wheel 108 to rotate.

[0127] In some embodiments, the automatic card issuing device 10 further includes a card issuing driving motor (not shown) disposed below the card storage slot and electrically connected to the card issuing active gear 103 , wherein the card issuing driving motor is used to drive the card issuing active gear 103 to rotate.

[0128] In some embodiments, a sensor 110 for detecting the cards to be printed in the card slot is disposed inside the card slot. When the number of cards to be printed in the card slot is less than a predetermined value, the sensor 110 generates a first sensing signal and sends the first sensing signal to the control system of the printer, and the control system of the printer sends a reminder message to remind to add cards. When all the printed cards in the card slot are removed, the sensor 110 generates a second sensing signal and sends the second sensing signal to the control system of the printer, and the control system controls the laser printing device to stop printing.

[0129] As an implementation, the sensor 110 may be a weight sensor that can detect the weight of the card to be printed in the card slot. When the weight of the card to be printed in the card slot detected by the sensor 110 is lower than a predetermined value, the sensor 110 generates a first sensing signal, and when the weight of the card to be printed in the card slot detected by the sensor 110 is zero, the sensor 110 generates a second sensing signal. As another implementation, the sensor 110 may be a photoelectric sensor that includes a light emitter and a light receiver. When the number (thickness) of the cards in the card slot exceeds a predetermined value, the photoelectric sensor is blocked, and the light emitted by the light emitter is reflected back to the light receiver, and the light receiver generates a sensing signal. When the number (thickness) of the cards in the card slot is lower than a predetermined value, the photoelectric sensor is exposed, and the light receiver cannot receive the reflected light, thereby generating another sensing signal.

[0130] In some embodiments, the distance between the first card issuing side plate 101 and the second card issuing side plate 102 matches the width of the card to be printed, and the front and rear edges of the first card issuing side plate 101 and the second card issuing side plate 102 are respectively bent vertically inward to form a limit plate 109 for limiting the card to be printed. In this way, the card to be printed can be conveniently stacked in the card storage slot in the vertical direction, and the card to be printed can be prevented from slipping out of the card storage slot.

[0131] To ensure that the card issuing transmission wheel 108 can only move one card to be printed out of the card storage slot at a time. In some embodiments, it also includes a card outlet (not shown) formed on one side of the card storage slot, and the size of the card outlet in the vertical direction matches the thickness of a card to be printed, and the card to be printed moves out of the card storage slot from the card outlet. In some preferred embodiments, the size of the card outlet in the vertical direction can be flexibly adjusted to meet the card output requirements of cards of various thicknesses.

[0132] 5. Introduction of card reader / writer

[0133] The above only briefly introduces the card reading and writing device 20. Figures 6 to 9 The specific structure of the card reading and writing device 20 in some embodiments is shown below. Figures 6 to 9 The card reading and writing device 20 is introduced in detail.

[0134] A fifth aspect of the present invention provides a card reader / writer device 20, which includes a card reader / writer frame, a card reader / writer module 201 and a card reader / writer drive mechanism.

[0135] The card reader / writer frame includes a first card reader / writer side plate 202 and a second card reader / writer side plate 203 which are arranged vertically and opposite to each other, and a read / write channel for the card to be printed to pass through is formed between the first card reader / writer side plate 202 and the second card reader / writer side plate 203. The card reader / writer module 201 is connected to the card reader / writer frame and is located above the read / write channel. The card reader / writer drive mechanism is used to drive the card to be printed to pass through the read / write channel so that the card reader / writer module 201 can read or write the card to be printed.

[0136] In some embodiments, the card reader / writer drive mechanism includes at least two sets of card reader / writer transmission wheel groups arranged in the read / write channel and a card reader / writer gear transmission structure arranged on the outer wall of the first card reader / writer side plate 202 or the second card reader / writer side plate 203 for driving the at least two sets of card reader / writer transmission wheel groups to rotate. The card reader / writer transmission wheel group includes a first card reader / writer transmission wheel and a second card reader / writer transmission wheel, and a gap is provided between the first card reader / writer transmission wheel and the second card reader / writer transmission wheel for the card to be printed to pass through. The card reader / writer gear transmission structure is used to drive the first card reader / writer transmission wheel or the second card reader / writer transmission wheel of each card reader / writer transmission wheel group to rotate, so as to drive the card to be printed to enter and pass through the gap between the first card reader / writer transmission wheel and the second card reader / writer transmission wheel. Preferably, the width of the read / write channel matches the width of the card to be printed, and the size of the gap between the first card reader / writer transmission wheel and the second card reader / writer transmission wheel matches the thickness of a card to be printed.

[0137] In some embodiments, the first card reader / writer transmission wheel of the card reader / writer transmission wheel set is a driving wheel, and the second card reader / writer transmission wheel is a driven wheel. That is, the card reader / writer gear transmission mechanism is only connected to the first card reader / writer transmission wheel and drives it to rotate. When the card to be printed enters the gap in the card reader / writer transmission wheel set, the first card reader / writer transmission wheel as the driving wheel can drive the second card reader / writer transmission wheel as the driven wheel to rotate in the opposite direction under the friction of the card, thereby driving the card to pass through the gap between the first card reader / writer transmission wheel and the second card reader / writer transmission wheel.

[0138] In other embodiments, the second card reader / writer transmission wheel of the card reader / writer transmission wheel set is a driving wheel, and the first card reader / writer transmission wheel is a driven wheel. That is, the card reader / writer gear transmission mechanism is only connected to the second card reader / writer transmission wheel and drives it to rotate. When the card to be printed enters the gap in the card reader / writer transmission wheel set, the second card reader / writer transmission wheel as the driving wheel can drive the first card reader / writer transmission wheel as the driven wheel to rotate in the opposite direction under the friction of the card, thereby driving the card to pass through the gap between the second card reader / writer transmission wheel and the first card reader / writer transmission wheel.

[0139] In some embodiments, the card reader / writer gear transmission mechanism includes a card reader / writer driving gear and at least two card reader / writer driven gears corresponding one by one to the at least two groups of card reader / writer transmission wheel groups. The card reader / writer gear transmission mechanism and each of the card reader / writer driven gears are connected via a card reader / writer belt, and each of the card reader / writer driven gears rotates via a transmission shaft and the first card reader / writer transmission wheel or the second card reader / writer transmission wheel of the corresponding card reader / writer transmission wheel group.

[0140] When the card reader / writer driving gear rotates, it can synchronously drive each of the card reader / writer driven gears to rotate to drive the first card reader / writer transmission wheel or the second card reader / writer transmission wheel of each card reader / writer transmission wheel group to rotate, thereby driving the card to pass through the gap between the first card reader / writer transmission wheel and the second card reader / writer transmission wheel of each card reader / writer transmission wheel group in sequence to pass through the card reader / writer device.

[0141] It can be seen that the gaps in each of the card reading and writing transmission wheel groups form a card conveying channel in the card reading and writing device 20. The card to be printed passes through each of the card reading and writing transmission wheel groups in sequence and thus passes through the card reading and writing device 20. In particular, the gaps in a group of the card reading and writing transmission wheel groups near one end of the card reading and writing device 20 constitute the feeding port of the card reading and writing device 20, and the gaps in a group of the card reading and writing transmission wheel groups near the other end of the card reading and writing device 20 constitute the discharging port of the card reading and writing device 20.

[0142] In order to ensure that the card to be printed can pass smoothly through the card reading and writing device 20, the distance between two adjacent groups of the card reading and writing transmission wheel groups is smaller than the length of the card to be printed.

[0143] Please refer to Figure 7 As shown, in some embodiments, the card reading and writing device 20 of the present invention includes two sets of the card reading and writing transmission wheel groups, wherein: one set of the card reading and writing transmission wheel groups is located at one end of the card reading and writing device 20 to form the feeding port of the card reading and writing device 20, and the other set of the card reading and writing transmission wheel groups is located at the other end of the card reading and writing device 20 to form the discharging port of the card reading and writing device 20. Both sets of the card reading and writing transmission wheel groups include a first card reading and writing transmission wheel 207 and a second card reading and writing transmission wheel 208.

[0144] The card reader / writer gear transmission mechanism includes a card reader / writer driving gear 204 and two card reader / writer driven gears 205 arranged on the first card reader / writer side plate 202. The card reader / writer driving gear 204 and the two card reader / writer driven gears 205 are connected via a card reader / writer belt 206. The two card reader / writer driven gears 205 are respectively connected to the first card reader / writer transmission wheel 207 of the corresponding card reader / writer transmission wheel group via a transmission shaft (not shown) passing through the first card reader / writer side wall 202.

[0145] The card to be printed enters the card reader / writer device 20 through a set of card reader / writer transmission wheel groups and moves forward under the drive of the card reader / writer transmission wheel groups to accept the card reading or writing operation. After completing the card reading or writing operation, the card to be printed leaves the card reader / writer device 20 through another set of the card reader / writer transmission wheel groups.

[0146] In some embodiments, the card reader / writer device 20 further includes a card reader drive motor (not shown) connected to the card reader / writer driving gear 204 , and the card reader / writer drive motor is used to drive the card reader / writer driving gear 204 to rotate.

[0147] Of course, in order to ensure that the card to be printed can pass smoothly through the card reading and writing device 20, the distance between the two sets of the card reading and writing transmission wheel sets is smaller than the length of the card to be printed.

[0148] In addition, in order to trigger the card reading and writing module 201 to perform a card reading or writing operation, in some embodiments, the card reading and writing device 20 also includes a position sensor (not shown) arranged below the card reading and writing module 201. When the card to be printed enters the card reading and writing device 20 and reaches a predetermined position, the position sensor is triggered and generates a sensing signal. After receiving the sensing signal, the card reading and writing module 201 performs a card reading or writing operation.

[0149] 6. Introduction of Printer Station

[0150] The above only briefly introduces the printer station 30. Figures 10 to 13 The specific structure of the printer table 30 in some embodiments is shown in FIG. Figures 10 to 13 The printer stage 30 is described in detail.

[0151] The sixth aspect of the present invention provides a printer table 30, which includes a flipping mechanism and a translation mechanism. The translation mechanism is used to drive the card to translate to reach or leave a predetermined printing position. The flipping mechanism can flip the card front and back to flip the current printing surface from the first printing surface to the second printing surface.

[0152] As mentioned above, the front-to-back flipping means that the flipping mechanism flips the current printing surface of the card from the first printing surface to the second printing surface in a translation direction parallel to the card. After the front-to-back flipping, the type of the current printing surface changes, but the direction remains unchanged.

[0153] like Figures 10 to 13 As shown, in some embodiments, the printer table 30 includes a table frame, a flip bracket and a flip driving mechanism arranged on the table frame.

[0154] The machine frame includes a first machine side plate 317 and a second machine side plate 318 that are arranged opposite to each other, and a transmission channel for the card to pass through is formed between the first machine side plate 317 and the second machine side plate 318.

[0155] The flip bracket is connected between the first machine side plate 317 and the second machine side plate 318, and is used to carry the card and drive the card to flip.

[0156] The flip driving mechanism is arranged on the outside of the machine frame and connected to the flip bracket, and is used to drive the flip bracket to flip forward and backward along the transmission channel to realize the flipping of the card, thereby realizing double-sided printing of the card.

[0157] It can be seen that the flip bracket and the flip driving mechanism constitute a flip mechanism of the printer table 30, which can realize the front and back flipping of the card in the transmission direction.

[0158] like Figures 10 to 13 As shown, in some embodiments, the flip bracket includes a first flip side panel 308 and a second flip side panel 315 that are relatively arranged, and one end of the first flip side panel 308 and the second flip side panel 315 are connected via a first connecting rod 312, and the other end of the first flip side panel 308 and the second flip side panel 315 are connected via a second connecting rod 313.

[0159] The flip driving mechanism includes a flip driving gear 301 and a flip driven gear 302 arranged on the outer wall of the first machine side plate 317, and the flip driving gear 301 and the flip driven gear 302 are connected via a flip belt 303. Among them: a through hole is formed on the first machine side plate 317, and the inner end of the flip driven gear 302 passes through the through hole and extends inward into the transmission channel. The second machine side plate 318 is provided with a rotating shaft 314 perpendicular to the second machine side plate 318.

[0160] The first flip side plate 308 of the flip bracket is connected to the inner end of the flip driven gear 302 and can rotate with the flip driven gear 302. The second flip side plate 315 of the flip bracket is connected to the rotating shaft 314 and can rotate around the rotating shaft 314. When the flip driving gear 301 drives the flip driven gear 302 to rotate via the flip belt 303, the flip bracket flips forward and backward along with the flip driven gear 302.

[0161] When the card to be flipped is located on the flip bracket and the central axis of the card is coaxial with the rotating shaft 314, the flip driving mechanism drives the flip bracket to rotate to achieve 180° in-situ flipping of the card. During the in-situ flipping process, the central axis of the card always remains coaxial with the rotating shaft 314, so after the in-situ flipping, the current printing surface of the card is flipped from the first printing surface to the second printing surface, and the position of the card on the printer table remains unchanged.

[0162] It can be seen that the installation axis of the rotating shaft 314 constitutes the central axis of the predetermined printing position. When the central axis of the card is coaxial with the rotating shaft 314, it means that the card has reached the predetermined printing position. At this time, continuous printing of the two printing surfaces of the card can be achieved by flipping the card, and there is no need to adjust the horizontal position of the card during the printing process.

[0163] The flip driving mechanism further includes a flip driving motor 319 connected to the flip driving gear 301, and the flip driving motor 319 is used to drive the flip driving gear 301 to rotate. In some embodiments, the first machine side plate 317 is provided with a flip driving motor installation opening corresponding to the flip driving gear 301, and the flip driving motor 319 passes through the flip driving motor installation opening.

[0164] In order to fix both sides of the card and push the card to translate on the flip bracket to reach or leave the predetermined printing position. Fig.12 and Fig.13 As shown, the printer station 30 also includes:

[0165] A plurality of translation transmission wheel groups are axially arranged on the first flip side plate 308, and the translation transmission wheel groups include a first translation transmission wheel 309 and a second translation transmission wheel 310. A translation gap is formed between the first translation transmission wheel 309 and the second translation transmission wheel 310 to clamp one side of the card and drive the card to translate on the flip bracket.

[0166] A translation guide groove 316 is axially arranged on the second flip side plate 315 and matches the translation gap. The translation guide groove 316 is used to clamp the other side of the card.

[0167] The translation driving mechanism is arranged outside the machine frame, and is used to drive the first translation driving wheel 309 or the second translation driving wheel 310 of each translation driving wheel group to rotate so as to drive the card to translate on the flip bracket.

[0168] It can be seen that the translation transmission wheel set, the translation guide groove 316 and the translation driving mechanism constitute the translation mechanism of the printer table 30, which can drive the card to translate on the flip bracket.

[0169] In some embodiments, the translation drive mechanism further includes a translation driving gear 304 and a translation driven gear set. The translation driving gear 304 is arranged on the outer wall of the first machine side plate 317, the translation driven gear set is arranged on the outer end of the flip driven gear 302, the translation driven gear set includes a first translation driven gear 305 and at least two second translation driven gears 307 linked with the first translation driven gear 305, the first translation driven gear 305 is arranged at the center of the outer end of the flip driven gear 302, the translation driving gear 304 is connected to the first translation driven gear 305 via a translation belt 306, and the at least two second translation driven gears 307 are connected to the at least two translation transmission wheel sets in a one-to-one correspondence.

[0170] In some embodiments, at least two transmission rods corresponding to the at least two second translation driven gears are passed through the flip driven gear 302, one end of the transmission rod is connected to one of the second translation driven gears 307, and the other end of the transmission rod is connected to a first translation transmission wheel 309 or a second translation transmission wheel 310 of a group of the translation transmission wheel groups.

[0171] When the translation driving gear 304 drives the first translation driven gear 305 to rotate via the translation belt 306, the first translation driven gear 305 drives each of the second translation driven gears 307 to rotate synchronously, and each of the second translation driven gears 307 drives the first translation transmission wheel 309 or the second translation transmission wheel 310 of each translation transmission wheel group to rotate synchronously through the connecting rod.

[0172] In some embodiments, the first translation driven gear 309 of the translation transmission wheel set is a driving wheel, and the second translation driven gear 310 of the translation transmission wheel set is a driven wheel, that is, the second translation driven gear 307 is connected to the first translation driven gear 309 of the translation transmission wheel set. When the card to be printed enters the gap in the translation transmission wheel set, the first translation driven gear 309 as the driving wheel can drive the second translation driven gear 310 as the driven wheel to rotate in the opposite direction under the friction of the card, thereby driving one side of the card to pass through the translation gap between the first translation driven gear 309 and the second translation driven gear 310 for horizontal translation, and synchronously, the other side of the card is horizontally translated along the translation guide groove 316.

[0173] Of course, in some other embodiments, the second translation driven gear 310 of the translation transmission wheel group is the driving wheel, and the first translation driven gear 309 of the translation transmission wheel group is the driven wheel, that is, the second translation driven gear 307 is connected to the second translation driven gear 310 of the translation transmission wheel group.

[0174] The translation drive mechanism further includes a translation drive motor 320 connected to the translation driving gear 304, and the translation drive motor 320 is used to drive the translation driving gear 304 to rotate. In some embodiments, the first machine side plate 317 is provided with a translation drive motor installation opening corresponding to the translation driving gear 304, and the translation drive motor 320 passes through the translation drive motor installation opening.

[0175] 7. Introduction of Automatic Card Dispensing Device

[0176] The above only briefly introduces the automatic card dispensing device 40. Figure 6 , Figure 10 to Figure 11 The specific structure of the automatic card dispensing device 40 in some embodiments is shown in FIG. Figure 6 , Figure 10 to Figure 11 The automatic card ejection device 40 is introduced in detail.

[0177] A seventh aspect of the present invention provides an automatic card ejection device 40, which is used to remove the printed card from the printer table 30 to achieve automatic card ejection.

[0178] The automatic card ejection device 40 comprises at least two sets of card ejection transmission wheel groups and a card ejection gear transmission mechanism for driving the at least two sets of card ejection transmission wheel groups to rotate, each of the card ejection transmission wheel groups comprises a first card ejection transmission wheel and a second card ejection transmission wheel, and a gap is provided between the first card ejection transmission wheel and the second card ejection transmission wheel for the card to pass through. The card ejection gear transmission mechanism is used to synchronously drive the first card ejection transmission wheel or the second card ejection transmission wheel of each card ejection transmission wheel group to rotate, so as to drive the printed card to enter and pass through the gap between the first card ejection transmission wheel and the second card ejection transmission wheel.

[0179] In some embodiments, the first card-ejecting transmission wheel of the card-ejecting transmission wheel set is a driving wheel, and the second card-ejecting transmission wheel is a driven wheel, and the card-ejecting gear transmission mechanism is only connected to the first card-ejecting transmission wheel and drives it to rotate. When the printed card enters the gap in the card-ejecting transmission wheel set, the first card-ejecting transmission wheel as the driving wheel can drive the second card-ejecting transmission wheel as the driven wheel to rotate in the opposite direction under the friction of the card, thereby driving the card to pass through the gap between the first card-ejecting transmission wheel and the second card-ejecting transmission wheel.

[0180] In other embodiments, the second card-ejecting transmission wheel of the card-ejecting transmission wheel set is a driving wheel, and the first card-ejecting transmission wheel is a driven wheel, and the card-ejecting gear transmission structure is only connected to the second card-ejecting transmission wheel and drives it to rotate. When the printed card enters the gap in the card-ejecting transmission wheel set, the second card-ejecting transmission wheel as the driving wheel can drive the first card-ejecting transmission wheel as the driven wheel to rotate in the opposite direction under the friction of the card, thereby driving the card to pass through the gap between the second card-ejecting transmission wheel and the first card-ejecting transmission wheel.

[0181] The card output gear transmission mechanism includes a card output driving gear and at least two groups of card output driven gears corresponding to the at least two groups of card output transmission wheel groups. The card output driving gear and each of the card output driven gears are connected via a card output belt, and each of the card output driven gears rotates via a transmission shaft and the first card output transmission wheel or the second card output transmission wheel of the corresponding card output transmission wheel group.

[0182] When the card output driving gear rotates, it can synchronously drive each of the card output driven gears to rotate to drive the first card output transmission wheel or the second card output transmission wheel of each card output transmission wheel group to rotate, thereby driving the card to pass through the gap between the first card output transmission wheel and the second card output transmission wheel of each card output transmission wheel group in sequence to pass through the card output device, thereby realizing automatic card output.

[0183] It can be seen that the gaps in each of the card output transmission wheel groups form a card transmission channel in the automatic card output device 40. The printed card passes through each of the card output transmission wheel groups in sequence and thus passes through the automatic card output device 40. In particular, the gaps in a group of the card output transmission wheel groups near one end of the automatic card output device 40 constitute the feed port of the automatic card output device 40, and the gaps in a group of the card output transmission wheel groups near the other end of the automatic card output device 40 constitute the discharge port of the automatic card output device 40.

[0184] In order to ensure that the printed card can pass smoothly through the automatic card output device 40, the distance between two adjacent sets of the card output transmission wheel sets is smaller than the length of the card to be printed.

[0185] In some embodiments, the automatic card ejection device 40 of the present invention includes two sets of the card ejection transmission wheel groups, wherein: one set of the card ejection transmission wheel groups is located at one end of the automatic card ejection device 40 to form the feed port of the automatic card ejection device 40, and the other set of the card ejection transmission wheel groups is located at the other end of the automatic card ejection device 40 to form the discharge port of the card ejection device. Both sets of the card ejection transmission wheel groups include a first card ejection transmission wheel (not shown) and a second card ejection transmission wheel 404.

[0186] Correspondingly, the card output gear transmission mechanism includes a card output driving gear 401 and two card output driven gears 402. The card output driving gear 401 and the two card output driven gears 402 are connected via a card output belt 403. The two card output driven gears 402 are respectively connected to the first card output transmission wheel of the corresponding card output transmission wheel group via a transmission shaft.

[0187] The printed card enters the automatic card discharging device 40 through a set of card discharging transmission wheel groups and moves forward under the drive of the card discharging transmission wheel groups, and finally leaves the card reading and writing device 20 through another set of the card discharging transmission wheel groups.

[0188] In some embodiments, the automatic card ejection device 40 further includes a card ejection driving motor connected to the card ejection driving gear 401 , and the card ejection driving motor is used to drive the card ejection driving gear 401 to rotate.

[0189] Of course, in order to ensure that the printed card can pass smoothly through the automatic card output device 40, the distance between the two sets of the card output transmission wheel sets is smaller than the length of the card to be printed.

[0190] Preferably, a compression spring is arranged on the outer side of the second card output transmission wheel as a driven wheel, and the compression spring enables the first card output transmission wheel and the second card output transmission wheel to compress the card.

[0203] exist Figure 18-Figure 21 In the specific embodiment shown, the plurality of first translation upper transmission wheels 931 are sequentially arranged on the inner side of the first photographing side plate 914; the plurality of second translation upper transmission wheels 933 are sequentially arranged on the inner side of the second photographing side plate 916.

When the second rotating shaft 922 drives the plurality of second translational upper transmission wheels 933 to flip to the initial position, the plurality of second translational upper transmission wheels 933 are placed perpendicular to the direction of the card, and a translational gap is formed between the second translational upper transmission wheel 933 and the second translational lower transmission wheel 934 opposite thereto to clamp the other side of the card and drive the card to translate; when the second rotating shaft 922 flips to the photographing position (which may also be referred to as the second position), the plurality of second translational upper transmission wheels 933 are placed parallel to the direction of the card so that the plurality of second translational upper transmission wheels 933 avoid (or do not block) the card 100.

[0205] It should be noted that, in other embodiments, when the several first translation upper transmission wheels 931 are flipped to the photographing position, the several first translation upper transmission wheels 931 may be placed non-parallel to the card direction, as long as the several first translation upper transmission wheels 931 avoid (or do not block) the card 100; similarly, when the several second translation upper transmission wheels 933 are flipped to the photographing position, the several second translation upper transmission wheels 933 may be placed non-parallel to the card direction, as long as the several second translation upper transmission wheels 933 avoid (or do not block) the card 100.

[0206] In order to drive the first rotating shaft 921 and the second rotating shaft 922 to rotate, Figure 18-Figure 21In the illustrated embodiment, the flip module 920 further includes a shaft driving mechanism (not labeled), which includes: a third shaft 923, the third shaft 923 being located at one end of the first shaft 921 and the second shaft 922 and being perpendicular to the first shaft 921 and the second shaft 922; a first gear 9212 being disposed at one end of the first shaft 921; a second gear 9222 being disposed at one end of the second shaft 922; a third gear 9232 being disposed at one end of the third shaft 923 and cooperating with the first gear 9212; a fourth gear 9234 being disposed at the other end of the third shaft 923 and cooperating with the second gear 9222; the third shaft 923 drives the first shaft 921 to rotate via the third gear 9232 and the first gear 9212, and the third shaft 923 drives the second shaft 922 to rotate via the fourth gear 9234 and the second gear 9222.

The shaft drive motor 926 is electrically connected to the shaft drive driving wheel 924, and the shaft drive motor 926 is used to drive the shaft drive driving wheel 924 to rotate, and the shaft drive driving wheel 924 drives the third shaft 923 to rotate via the belt and the shaft drive driven wheel 925.

[0208] It should be noted that, in another embodiment, a rotating shaft driving mechanism with other structures may also be used to drive the first rotating shaft 921 and the second rotating shaft 922 to rotate.

[0209] exist Figure 18-Figure 21 In the embodiment shown, the non-blocking ID card photography device further includes a sensor 940, and the sensor 940 is used to detect whether the plurality of first translation upper transmission wheels 931 and the plurality of second translation upper transmission wheels 933 are flipped in place, that is, to detect whether the plurality of first translation upper transmission wheels 931 and the plurality of second translation upper transmission wheels 933 are flipped to the photography position. For example, when the sensor 940 detects that the plurality of first translation upper transmission wheels 931 and the plurality of second translation upper transmission wheels 933 are flipped to the photography position, it outputs a flipping in place signal.

[0210] exist Figure 18-Figure 21In the specific embodiment shown, the sensor 940 includes a baffle 942 and a photoelectric sensor 944. The baffle 942 is disposed on the first rotating shaft 921, and the photoelectric sensor 944 is located outside the first photographing side plate 914 and close to the first rotating shaft 921. When the first rotating shaft 921 drives the first translation upper transmission wheels 931 to rotate away from the photographing position, the baffle 942 flips to the outside of the photoelectric sensor 944, and the transmitting and receiving optical path in the photoelectric sensor 944 is unblocked, so that the sensor 940 generates a first sensing signal; when the first rotating shaft 921 drives the first translation upper transmission wheels 931 to flip to the photographing position, the baffle 942 flips to the inside of the photoelectric sensor 944 to block the transmitting and receiving optical path in the photoelectric sensor 944, so that the sensor 940 generates a second sensing signal (i.e., the flip-in-place signal).

[0211] The shooting camera 91 is located above the shooting frame 910 of the unobstructed ID card shooting device 90 . The shooting camera 91 is used to take a picture of the ID card 100 carried in the transmission channel 912 of the shooting frame 910 .

[0212] In order to facilitate the understanding of the present invention, the following specific introduction Figure 18-Figure 21 The working process of the unobstructed card photography device shown.

[0213] When the card 100 needs to be translated to the pre-photographing position, the plurality of first translation upper transmission wheels 931 and the plurality of second translation upper transmission wheels 933 are both in the initial position. The plurality of first translation upper transmission wheels 931 are placed perpendicular to the card direction, and a translation gap is formed between the first translation upper transmission wheels 931 and the first translation lower transmission wheels 932 opposite thereto, so as to clamp one side of the card 100 and drive the card to translate; the plurality of second translation upper transmission wheels 933 are placed perpendicular to the card direction, and a translation gap is formed between the second translation upper transmission wheels 933 and the second translation lower transmission wheels 934 opposite thereto, so as to clamp the other side of the card 100 and drive the card to translate. At this time, the translation upper transmission wheels 931, 933 and the translation lower transmission wheels 932, 934 play the role of conveying the card 100.

[0214] When the card 100 is translated along the transmission channel 921 to the predetermined photographing position and needs to be photographed, the third rotating shaft 923 rotates in the second rotating direction, and the first rotating shaft 921 is driven to rotate via the third gear 9232 and the first gear 9212, so that the first translation upper transmission wheels 931 are turned over to the photographing position, and the second rotating shaft 922 is driven to rotate via the fourth gear 9234 and the second gear 9222, so that the second translation upper transmission wheels 933 are turned over to the photographing position. The first translation upper transmission wheels 931 are placed parallel to the card direction, so that the first translation upper transmission wheels 931 avoid the card 100; the second translation upper transmission wheels 933 are placed parallel to the card direction, so that the second translation upper transmission wheels 933 avoid the card 100. That is, when the card at the predetermined photographing position needs to be photographed, the first translation upper transmission wheels 931 and the second translation upper transmission wheels 933 are opened. At this time, the baffle 942 enters the photoelectric sensor 944, and the sensor 940 generates and outputs a flip-in-place signal. Subsequently, the camera 91 located above the camera frame 910 takes a photo of the card 100 located at the pre-photographing position.

[0215] When the card 100 needs to be translated to leave the predetermined photographing position after the photographing is completed, the third rotating shaft 923 rotates in the first rotating direction (the first rotating direction is opposite to the second rotating direction), and the first rotating shaft 921 is driven to rotate via the third gear 9232 and the first gear 9222, so that the first translation upper transmission wheels 931 are turned over to the initial position, and the second rotating shaft 922 is driven to rotate via the fourth gear 9234 and the second gear 9222, so that the second translation upper transmission wheels 933 are turned over to the initial position. In other words, when the card needs to be translated to reach or leave the predetermined photographing position, the first translation upper transmission wheels 931 and the second translation upper transmission wheels 933 are reset (or closed). Subsequently, the translation module 930 transmits the card 100 in the original direction or the reverse direction.

[0216] The following describes the use of the non-blocking ID card photographing device 90 of the laser printing system.

[0217] When performing single-sided printing, please refer to the laser printing method described above for the preceding printing steps. When the ID card 100 is transmitted to the unobstructed ID card camera device 90, the shaft drive motor 926 starts working, and the shaft drive driving wheel 924 on the side drives the shaft drive driven wheel 925 at one end of the third shaft 923 to rotate. The rotation of the third shaft 923 drives the third gear 9232 and the fourth gear 9234 at both ends of the third shaft 923 to rotate. The third gear 9232 and the fourth gear 9234 drive the first gear 9212 and the second gear 9222 to rotate respectively.

At this time, the shooting camera 91 takes a picture. After the picture is taken, the first upper translation transmission wheel 931 and the second upper translation transmission wheel 933 are restored to the initial position to transmit the card 100 along the original direction.

[0218] When double-sided printing is performed, after single-sided printing is completed, the first translation upper transmission wheel 931 and the second translation upper transmission wheel 933 of the unobstructed photographing device 90 are restored to the initial position, and the card 100 is conveyed in the reverse direction to the printer table 30 for flipping. After the flipping is completed, the above steps are repeated, and the back side of the card 100 is photographed again without obstruction, and finally the card 100 is conveyed out in the original direction.
