Background

The certificate card is used for proving certificates and documents of identities, experiences and the like, such as personal certificates of identity cards, drivers licenses and the like. Personalized information such as a portrait, a name, an age and the like of a person on a document such as an identity card, a driver's license, a passport and the like needs to be printed by a printer. The identification card to be printed generally comprises two printing surfaces, namely a positive printing surface and a reverse printing surface.

The laser printing system is a commonly used card printing device, and generally comprises a control system, a printing machine platform and a laser printing device, wherein the printing machine platform and the laser printing device are in communication connection with the control system, and the laser printing device comprises: the printing machine platform is used for bearing the card to be printed, and the laser printing device prints the target printing information on the current printing surface of the card to be printed according to the printing instruction sent by the control system.

In some printing practices, the card to be printed is preprinted with specific common template information on both the front and reverse printed sides. The laser printing system needs to print out printing information (namely personalized information) matched with the public template information in the preset areas of the positive printing surface and the negative printing surface of the identification card, and the public template information and the printing information form the printed complete card surface information. Of course, the common template information, the print information may include text and/or images.

Obviously, during the printing process, the type of the current printing surface of the card to be printed may be a positive printing surface or a negative printing surface, and the placement direction of the card to be printed may be a positive position or a negative position. Therefore, before the current printing surface of the card to be printed is printed, the type and the direction of the current printing surface of the card must be determined in advance, and then the printing information matched with the common template information on the current printing surface can be printed on the current printing surface in the correct direction.

However, the laser printing system in the prior art cannot realize the real-time identification of the type and the direction of the current printing surface of the card to be printed. Therefore, in order to ensure the accuracy of the printing information, before the cards to be printed are printed, the types and the printing directions of the printing surfaces of the laser printing system are generally set uniformly, and then the types and the directions of the printing surfaces 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 setting of the printer. For example: when the laser printing system is set to be used for printing on the printing face and in the forward direction, all the cards to be printed are placed with the printing faces facing upwards, and all the cards to be printed are placed in the forward direction.

Therefore, when the laser printing system in the prior art is used for printing the identification card, the type and the direction of the identification card to be printed need to be adjusted in advance manually, and the method is time-consuming, labor-consuming and low in efficiency.

In addition, the certificate card needs to be photographed manually in the printing process or after the printing process is finished so as to facilitate subsequent identification and verification, and the method is time-consuming, labor-consuming and low in efficiency.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

Fig. 1-16 illustrate a first embodiment of a laser printing system, and fig. 17-18 illustrate a second embodiment of a laser printing system, which is the preferred embodiment of the laser printing system.

Introduction to laser printing System

In order to more clearly show the technical problem to be solved by the first aspect of the present invention. By way of example, we describe the printing requirements of the card to be printed in some specific printing scenarios. As shown in fig. 14, it shows four possible states of the current printing side of a card to be printed, among which:

a in fig. 14 shows a state where the type of the current printing surface of the card to be printed is a positive printing surface and the direction is positive.

B in fig. 14 shows the state where the type of the current printing surface of the card to be printed is a positive printing surface and the direction is inverted.

The c in fig. 14 shows the state where the type of the current printing surface of the card to be printed is the reverse printing surface and the direction is the normal position.

D in FIG. 14 shows the status of the card to be printed in the state that the type of the current printing surface is the reverse printing surface and the direction is upside down.

As shown in a and b in fig. 14, public template information such as "name", "gender", "nationality", "identification card", "address" and the like is preprinted on the front printing surface of the identification card to be printed. As shown in c and d in fig. 14, the reverse printing side of the card to be printed is preprinted with common template information of "validity period to 2028-05-01".

The laser printing system needs to print out the printing information matched with the public information in the specific areas (shown by a dotted line frame in the figure) of the positive printing surface and the negative printing surface of the card to be printed. Of course, for the above four different states of the current printing surface, the printing information matched with the current printing surface must be selected and printed in the corresponding printing direction. Referring to fig. 16, a, b, c, d in fig. 16 show the qualified printing effect for the four different types and different directions of the printing surfaces in fig. 14.

The laser printing system in the prior art can not realize the real-time identification of the type and the direction of the current printing surface of the card to be printed. Therefore, in order to ensure the accuracy of the printing information, before the cards to be printed are printed, the types and the printing directions of the printing surfaces of the laser printing system are generally set uniformly, and then the types and the directions of the printing surfaces of all the cards to be printed are adjusted uniformly so as to ensure that the state of each card to be printed is consistent with the setting of the laser printing system. For example: when the laser printing system is set to be used for printing on the printing face and in the forward direction, all the cards to be printed are placed with the printing faces facing upwards, and all the cards to be printed are placed in the forward direction. Therefore, when the laser printing system in the prior art is used for printing, the type and the direction of the card to be printed need to be adjusted in advance manually and uniformly.

In view of the above technical defect that laser printing system among the prior art exists, the utility model discloses a first aspect provides a laser printing system, should laser printing system can realize treating the type and the direction of the current face of printing the card and advance real-time, automatic identification. Therefore, use the utility model discloses a laser printing system that first aspect provided prints the card, it need not treat in advance and prints type, the direction of card and carry out unified adjustment, can accomplish in proper order promptly and treat two continuous printings of printing the face of printing of card. For convenience of description, we define the printing side to be printed first as the first printing side and the printing side to be printed later as the second printing side in the order of printing. That is to say, the utility model discloses a laser printing system prints card that the first aspect provided can accomplish the continuous printing to the first printing face of card, second printing face in proper order.

Of course, the type of the first printing surface may be a positive printing surface or a reverse printing surface, and the second printing surface is another printing surface opposite to the type of the first printing surface.

Referring to fig. 1 to 5, fig. 1 to 5 show schematic structural diagrams of a first embodiment of the laser printing system provided by a first aspect of the present invention from different viewing angles. As shown in fig. 1 to 5, the laser printing system includes a printer platform 30, a laser printing device 60, and a control system 70, wherein the printer platform 30 and the laser printing device 60 are respectively connected to the control system 70 in a communication manner.

Wherein:

the printer station 30 includes a translation mechanism for driving the identification card to translate to reach or leave a predetermined printing position, and a turnover mechanism for turning over the identification card to turn over the current printing surface of the identification card from the first printing surface to the second printing surface.

Wherein the current printing surface is the printing surface of the identification card exposed under the laser printing device 60. The predetermined printing position is located on the printer platform 30, and when the identification card is translated to the predetermined printing position, the laser printing device 60 can print the current printing surface of the identification card. The turnover mode of the turnover mechanism is a front-back turnover mode or a left-right turnover reverse mode, wherein:

the front-back overturning mode is that the overturning mechanism overturns the current printing surface of the card from the first printing surface to the second printing surface according to the translation direction parallel to the card, after the front-back overturning, the type of the current printing surface is changed, and the direction is kept unchanged. Referring to fig. 14, for example, if the current first printing surface of the identification card is a (type is a front printing surface, direction is a positive position) in fig. 14, after the front and back are turned over, the current second printing surface of the identification card is c (type is a reverse printing surface, direction is a positive position) in fig. 14.

The left-right overturning mode is that the overturning mechanism overturns the current printing surface of the identification card from a first printing surface to a second printing surface according to the translation direction perpendicular to the identification card, and after left-right overturning, the type and the direction of the current printing surface are changed. Continuing with FIG. 14, for example, if the current first printing surface of the identification card is a (type is positive printing surface, direction is positive) in FIG. 14, after left-right flipping, the current second printing surface of the identification card is d (type is negative printing surface, direction is reverse) in FIG. 14.

The control system 70 can acquire the information to be printed, and the control system 70 can also judge the type and the direction of the current printing surface of the identification card, generate a printing information template matched with the type and the direction of the current printing surface based on the information to be printed, and send the printing information template to the laser printing device 60.

In some embodiments, the control system 70 generates a printing information template set based on the information to be printed after acquiring the information to be printed, where the printing information template set includes printing information templates that are matched with the types and directions of the printing surfaces of the identification cards one by one. Referring to fig. 14, as an exemplary description, for the card to be printed in fig. 14, the information to be printed includes the identity information in the dashed box of a in fig. 15 and the illustrative information in the dashed box of c in fig. 15. The printing information templates include four printing information templates which are matched with the types and directions of the printing surfaces of the identification cards one by one, and are respectively the printing information templates shown in a in fig. 15, b in fig. 15, c in fig. 15 and d in fig. 15. Wherein: the print information template shown by a in fig. 15 matches the print face (type is the front print face, orientation is right) shown by a in fig. 14; the print information template shown in b in fig. 15 matches the print side (type is the front print side, direction is reverse) shown in b in fig. 14; the print information template shown in c in fig. 15 matches the print face (type is reverse print face, direction is right) shown in c in fig. 14; the print information template shown by d in fig. 15 matches the print face (type is reverse print face, direction is reverse) shown by d in fig. 14.

In these embodiments, after determining the type and direction of the current printing surface, the control system 70 selects a matching printing information template from the set of pre-generated printing information templates according to the type and direction of the current printing surface, and sends the selected printing information template to the laser printing apparatus 60. For example, when the current printing surface of the identification card is the printing surface shown as a in fig. 14, the control system 70 sends the printing information template shown as a in fig. 15 to the laser printing device 60. The laser printing device 60 prints out the characters and/or patterns corresponding to the printing information template on the current printing surface of the identification card.

In other embodiments, the control system 70 only stores the information to be printed after acquiring the information, and does not generate the print information template set. In these embodiments, after determining the type and the direction of the current printing surface, the control system 70 generates a printing information template matching the type and the direction of the current printing surface based on the information to be printed according to the type and the direction of the current printing surface, and sends the printing information template to the laser printing apparatus 60.

The laser printing apparatus 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 on the printer table 30 at high speed, so as to realize laser printing on the current printing surface of the card to be printed, which is carried on the printer table 30.

Referring to fig. 14 to 16 again, for four different printing surfaces (a to d in fig. 14), the laser printing device 60 obtains corresponding different printing information templates (a to d in fig. 15), and prints the information of the printing information templates onto the printing surfaces. The printing effect after completion of printing is shown as a to d in fig. 16.

Manner of controlling system to obtain information to be printed

In some embodiments, the information to be printed is pre-stored in the identification card to be printed prior to printing. In these embodiments, the present invention provides a laser printing system, further comprising a card reading and writing device 20 communicatively connected to the control system 70, wherein the card reading and writing device 20 is disposed on one side of the printer platform 30. Before entering the printer station 30 to accept printing, the card to be printed 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, so that the control system 70 acquires the information to be printed.

In other embodiments, the control system 70 is communicatively connected to an external host computer, and the information to be printed is generated by the host computer. Before printing, the upper 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 may be pre-stored in the control system 70 before printing. When printing, the control system 70 may directly retrieve the information to be printed.

Method for judging type and direction of first printing surface by control system

The utility model provides a laser printing system is still including setting up the camera device 50 of printer platform 30 top, camera device 50 with control system 70 communication is connected. The camera device 50 includes a camera for acquiring an image of the identification card.

Preferably, the camera device 50 further includes a light source, and light emitted by the light source can irradiate onto the printer platform 30 to improve the imaging quality.

When the card to be printed reaches the preset printing position of the printer platform 30, the image capturing device 50 acquires the current image of the first printing surface of the card and sends the current image of the first printing surface to the control system 70, and the control system 70 identifies the image of the first printing surface through an image identification technology to determine the type and the direction of the first printing surface.

The image recognition technology is well known to those skilled in the art, and the detailed implementation and detailed process thereof will not be described in the present specification. For example, as an optional implementation manner, the control system 70 prestores standard reference images of different types and different directions of printing surfaces of cards to be printed, and the control system 70 can determine the type and the direction of the first printing surface by comparing the acquired image of the first printing surface with each standard reference image one by one. Specifically, the method comprises the following steps:

since the two printed sides of the card to be printed are pre-printed with the common template information, in some embodiments, the control system 70 determines the type and orientation of the first printed side by identifying the common template information in the image of the first printed side.

In order to reduce the identification difficulty, in other embodiments, corresponding printing surface identification marks are respectively pre-printed on 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 recognizing the printing surface recognition mark in the first printing surface.

As shown in FIG. 14, the lower right corner of the front printing surface of the card to be printed is pre-printed with a right-angled mark with an upward opening, and the upper right left corner of the reverse printing surface of the card to be printed is pre-printed with a right-angled mark with a downward opening. The type and the direction of the current first printing surface can be identified by identifying the printing position and the opening direction of the right-angle mark on the current first printing surface.

Manner of judging type and direction of second printing surface by control system

After the printing of the current first printing surface of the identification card is completed, the turnover mechanism on the printer table 30 turns over the identification card, so that the current printing surface of the identification card is turned over into a second printing surface.

In some embodiments, the control system determines the type and orientation of the second print side based on the type and orientation of the first print side and the predetermined flipping pattern. For example, when the control system 70 controls the turnover mechanism to turn the identification card back and forth in a direction parallel to the translation direction of the identification card so as to turn the current printing surface of the identification card from the first printing surface to the second printing surface. The control system 70 determines that the current type of the second printing side is opposite to the type of the first printing side and the second printing side is oriented in the same direction as the first printing side. For another example, when the turnover mechanism turns the identification card left and right in a direction perpendicular to the translation direction of the identification card, the current printing surface of the identification card is turned over from the first printing surface to the second printing surface. The control system 70 determines that the current type of the second printing side is opposite to the type of the first printing side and the second printing side is opposite to the first printing side.

Of course, in other embodiments, the type and orientation of the second printing surface may be determined in the same manner as the first printing surface. Specifically, when the turnover mechanism turns over the current first printing surface into the second printing surface, the image capturing device 50 obtains the current image of the second printing surface of the certificate card and sends the current image of the second printing surface to the control system 70, and the control system 70 identifies the image of the second printing surface by using an image identification technology to determine the type and the direction of the second printing surface.

Referring to fig. 1 to 6, in some preferred embodiments, the laser printing system of the present invention further includes an automatic card issuing device 10 disposed on one side of the printer 30 and an automatic card discharging device 40 disposed on the other side of the printer 30.

The automatic card issuing device 10 is used for storing at least one card to be printed and transmitting the card to be printed to the printer table 30 one by one to realize automatic card issuing. Of course, if the laser printing system includes the card reading and writing device 20, the card reading and writing device 20 is disposed between the automatic card issuing device 10 and the printer platform 30. After the automatic card issuing device 10 issues the card, the card firstly passes through the card reading and writing device 20 and then enters the printer table 30.

The automatic card discharging device 40 is used for moving the printed certificate card out of the printer platform 30 to realize automatic card discharging.

Furthermore, a card receiving device 80 may be disposed on one side of the automatic card discharging device 40, and the card receiving device 80 collects and stores the printed identification cards.

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

Introduction of laser printing system with galvanometer checking function

The laser printing system according to the first aspect of the present invention, wherein the laser printing device 60 comprises 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 on the printer table 30 at high speed, so as to realize laser printing on the current printing surface of the card to be printed, which is carried on the printer table 30.

During the printing process, if the scanning galvanometer 601 cannot move along a predetermined track strictly due to a fault, the laser printing device 60 cannot print correctly. In addition, if the scanning galvanometer 601 breaks down, a laser focus spot may stay in a specific area of the identification card for a long time in the printing process, and finally the identification card is ablated and even a fire is caused, so that before the current printing surface of the identification card is printed, the scanning galvanometer 601 needs to be verified to ensure that the scanning galvanometer 601 is in a normal working state.

In the prior art, in order to implement the check before printing of the scanning galvanometer 601, a special self-checking system is generally required to be additionally installed on the laser printing system, and the self-checking system increases the cost and the system complexity of the laser printing system.

The second aspect of the utility model provides a possess laser printing system who shakes mirror check-up function, this laser printing system's structure and printing theory of operation and the utility model discloses a laser printing system that the first aspect provided is basically the same, and its characteristics that structurally exist lie in: the laser printing apparatus 60 also includes an indicator light source that emits 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 that is integrally integrated with the laser light source. In other embodiments, the indicating light source is attached to one side of the laser light source and is mounted next to the laser light source.

When the indicating light source is turned on, the scanning galvanometer 601 can focus the light path of the indicating light source to form an indicating light focus spot, and can control the indicating light focus spot to scan on the printer table 30 at a high speed according to a predetermined track 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 track.

For example, if the predetermined trajectory is a circle with a diameter of 2 cm, the verification pattern should also be a circle with a diameter of 2 cm if the scanning galvanometer 601 is in a normal operating state.

The camera 50 can acquire an image of the verification pattern and send image information to the control system 70. The control system 70 performs verification of the scanning galvanometer by analyzing the received image information. If the control system 70 determines that the working state of the scanning galvanometer 601 is abnormal, the control system 7 controls the laser printing device 60 to stop printing, and if the control system 70 determines that the working state of the scanning galvanometer 601 is normal, the control system 7 controls the laser printing device 60 to start printing.

In some embodiments, the control system 70 analyzes the received image information via image recognition techniques to effect verification of the scanning galvanometer.

The image recognition technology is well known to those skilled in the art, and the detailed implementation and detailed process thereof are not described in the present specification. For example, as an alternative implementation, the control system 70 prestores a desired verification image formed when the scanning galvanometer 601 moves along the predetermined track under a normal operation state.

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.

The control system 70 can determine whether the state of the scanning galvanometer is normal by comparing the acquired image of the verification pattern with the expected verification image. Specifically, the method comprises the following steps:

and when the image of the verification pattern is consistent with the expected verification image, the control system judges that the scanning galvanometer is in a normal working state.

And when the image of the verification pattern is inconsistent with the expected verification image, the control system judges that the scanning galvanometer is in an abnormal working state.

Third, introduction of printing method of laser printing system

The utility model discloses the third aspect provides a laser printing system's printing method, laser printing system is introduced above the utility model discloses the laser printing system that the first aspect or the second aspect provided.

As shown in fig. 1 to 5, the laser printing system includes a printer platform 30, a camera device 50, a laser printing device 60, and a control system 70, wherein the printer platform 30, the laser printing device 60, and the camera device 50 are respectively in communication connection with the control system 70. The utility model provides a laser printing system's printing method can realize treating the continuous printing of printing the card and including first printing surface and second printing surface.

In an embodiment, the present invention provides, in a third aspect, a printing method of a laser printing system, including:

step 1, the control system 70 acquires information to be printed and generates a printing information template set based on the information to be printed, wherein the printing information template set comprises printing information templates which are matched with the types and the directions of the printing surfaces of the identification cards one by one.

Referring to fig. 14 and 15, as an exemplary description, the information to be printed includes identity information in a dashed box of fig. 15 a and explanatory information in a dashed box of fig. 15 c. The printing information templates comprise four printing information templates which are matched with the types and the directions of the printing surfaces of the identification cards one by one, and are respectively shown as a in fig. 15, b in fig. 15, c in fig. 15 and d in fig. 15. Wherein: the print information template shown by a in fig. 15 matches the print face (type is the front print face, orientation is right) shown by a in fig. 14; the print information template shown in b in fig. 15 matches the print side (type is the front print side, direction is reverse) shown in b in fig. 14; the print information template shown in c in fig. 15 matches the print face (type is reverse print face, direction is right) shown in c in fig. 14; the print information template shown by d in fig. 15 matches the print face (type is reverse print face, direction is reverse) shown by d in fig. 14.

In some embodiments, the information to be printed is pre-stored in the identification card to be printed prior to printing. In these embodiments, the laser printing system further includes a card reader 20 communicatively connected to the control system 70, and the card reader 20 is disposed on one side of the printer platform 30. Before entering the printer station 30 to accept printing, the card to be printed 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, so that the control system 70 acquires the information to be printed.

In other embodiments, the identification card to be printed is a white card, in which no information is stored. In these embodiments, the control system 70 may be communicatively connected to an external upper computer, and the information to be printed is generated by the upper computer. Before printing, the upper 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 reading and writing device 20, and controls the card reading and writing device 20 to write the information to be printed into the identification card.

And step two, the translation mechanism of the printer table 30 translates the certificate card to be printed to a preset printing position, and after the certificate card to be printed reaches the preset printing position, the camera device 50 acquires the image of the current first printing surface of the certificate card and sends the image to the control system 70.

In some embodiments, during the process of translating the identification card to be printed to the predetermined printing position by the translating mechanism of the printer platform 30, the control system 70 determines whether the identification card reaches the predetermined printing position every predetermined time, and stops translating when the identification card reaches the predetermined printing position. Specifically, the specific process of the control system 70 determining whether the identification card reaches the predetermined printing position is as follows: the camera device 50 obtains an image of the identification card to be printed and sends the image to the control system 70, and the control system 70 analyzes the received image of the identification card to be printed by using an image recognition technology to judge whether the identification card to be printed reaches the preset printing position. The image recognition technology is well known to those skilled in the art, and the detailed implementation and detailed process thereof will not be described in the present specification. For example, as an optional implementation manner, a standard reference image of the identification card to be printed at the predetermined printing position is pre-stored in the control system 70, and the control system 70 can identify whether the identification card to be printed reaches the predetermined printing position by comparing the received image of the identification card to be printed with the standard reference image.

Step three, the control system 70 identifies the received image of the first printing surface to judge the type and the direction of the first printing surface, and selects a first printing information template matched with the type and the direction of the first printing surface from the printing information templates in a centralized manner to be sent to the laser printing device 60, and the laser printing device 60 prints patterns and/or characters corresponding to the first printing information template on the first printing surface.

In some embodiments, the control system 70 employs image recognition techniques to enable identification of the type and orientation of the first printed side. The image recognition technology is well known to those skilled in the art, and the detailed implementation and detailed process thereof will not be described in the present specification. For example, as an optional implementation manner, the control system 70 prestores standard reference images of different types and different directions of printing surfaces of cards to be printed, and the control system 70 can determine the type and the direction of the first printing surface by comparing the acquired image of the first printing surface with each standard reference image one by one.

Since the two printing sides of the card to be printed are preprinted with the common template information, in some embodiments, the control system 70 determines the type and direction of the first printing side by identifying the common template information in the image of the first printing side.

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

In addition, in some preferred embodiments, after the printing of the first printing surface of the certificate card is completed, a step of verifying the printing effect of the first printing surface is further included, if the first printing surface is qualified to be printed, the certificate card is turned over to realize the printing of the second printing surface, otherwise, the control system 70 controls the translation mechanism of the printer station 30 to directly move the current certificate card out of the printer station 30 as a waste card. Specifically, the inspection step specifically comprises: the camera device 50 acquires the image of the first printed surface after the certificate card is printed and sends the image to the control system 70; the control system 70 analyzes the received image of the printed first printing side by image recognition technology to determine whether the current first printing side is qualified for printing. As such, the image recognition techniques referred to herein are well known to those skilled in the art, and the detailed implementation and process thereof will not be described in detail herein. For example, as an optional implementation manner, a standard reference image of the first printing surface after being correctly printed is prestored in the control system, and the control system can identify whether the current first printing surface is eligible for printing by comparing the received image of the first printing surface after being printed with the standard reference image.

Step four: the turnover mechanism of the printer platform 30 turns over the identification card to turn over the current printing surface of the identification card into a second printing surface. The control system 70 judges the type and the direction of the second printing surface based on the type of the first printing surface and the overturning mode of the overturning mechanism, selects a second printing information template matched with the type and the direction of the second printing surface from the printing information templates in a centralized manner, and sends the second printing information template to the laser printing device 60, and the laser printing device 60 prints patterns and/or characters corresponding to the second printing information template on the second printing surface.

In some embodiments, the turnover mechanism turns over the identification card in a front-back turnover mode parallel to the translation direction of the identification card so as to turn over the current printing surface of the identification card from the first printing surface to the second printing surface. In these embodiments, the control system 70 determines that the current type of the second printing side is opposite to the type of the first printing side, and the orientation of the second printing side is the same as the orientation of the first printing side.

In other embodiments, the turnover mechanism turns over the identification card in a left-right turnover mode perpendicular to the translation direction of the identification card so as to turn over the current printing surface of the identification card from the first printing surface to the second printing surface. In these embodiments, the control system 70 determines that the current second printing side is of the opposite type and orientation to the first printing side.

Introduction of automatic card issuing device

The automatic card issuing device 10 has been described briefly above, and the specific structure of the automatic card issuing device 10 in some embodiments is shown in fig. 6 to 9, and the automatic card issuing device 10 is described in detail below with reference to fig. 6 to 9.

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 card to the printer 30 for automatic card issuing. The automatic card-issuing device 10 includes a card-issuing rack and a card-issuing drive mechanism, wherein:

the card-issuing machine frame comprises a first card-issuing side plate 101, a second card-issuing side plate 102 and a supporting plate 106, wherein the first card-issuing side plate 101 and the second card-issuing side plate 102 are vertically and oppositely arranged, the supporting plate 106 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 in the supporting plate 106. The first card-issuing side plate 101, the second card-issuing side plate 102 and the support plate 106 form a card storage slot for storing at least one card to be printed.

The card issuing driving mechanism is used for moving 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 comprises a card issuing driving wheel 108 and a card issuing gear driving structure. The hairpin driving wheel 108 is located below the card storage slot, and the hairpin driving wheel 108 penetrates through the driving window 107 upwards and is slightly higher than the upper surface of the supporting plate 106. The hairpin gear transmission structure is connected with the hairpin transmission wheel 108 and drives the hairpin transmission wheel 108 to rotate, so that the card to be printed, which is positioned in the card storage slot and is in contact with the supporting plate 106, is moved out of the card storage slot.

In some embodiments, as shown in fig. 7 and 8, the hairpin gear transmission structure includes a hairpin driving gear 103 and a hairpin driven gear 104 disposed on the first hairpin side plate 101, the hairpin driving gear 103 and the hairpin driven gear 104 are connected via a hairpin belt 105, and the hairpin transmission wheel 108 is connected to the hairpin driven gear 104 via a transmission shaft penetrating through the first hairpin side plate 101.

When the hairpin driving gear 103 rotates, it can drive the hairpin driven gear 104 to rotate so as to drive the hairpin drive wheel 108 to rotate.

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

In some embodiments, a sensor 110 for detecting the identification card to be printed in the card storage slot is disposed inside the card storage slot. When the number of the identification cards to be printed in the card storage slot is less than a preset value, the sensor 110 generates a first sensing signal and sends the first sensing signal to a control system of the printer, and the control system of the printer sends out reminding information to remind that the identification cards are added. When all the printing cards in the card storage slot are moved out, the sensor 110 generates a second sensing signal and sends the second sensing signal to a control system of the printer, and the control system controls the laser printing device to stop printing.

As an implementation manner, the sensor 110 may adopt a weight sensor, which can detect the weight of the identification card to be printed in the card storage slot, when the weight of the identification card to be printed in the card storage 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 identification card to be printed in the card storage slot detected by the sensor 110 is zero, the sensor 110 generates a second sensing signal. As another implementation, the sensor 110 may use a photoelectric sensor including a light emitter and a light receiver. When the number (thickness) of the cards in the card storage slot exceeds a preset value, the photoelectric sensor is shielded, light rays emitted by the light emitter are reflected back to the light receiver, and the light receiver generates a sensing signal. When the number (thickness) of the cards in the card storage slot is lower than a preset value, the photoelectric sensor is exposed, and the light receiver cannot receive reflected light, so that another sensing signal is generated.

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 10 are respectively bent inward vertically to form a limit plate 109 for limiting the card to be printed. So set up, can conveniently will wait to print the card and stack along vertical direction and be in store up in the card slot to prevent to wait to print the card and follow the card slot roll-off of storing up.

To ensure that the card issuing driving wheel 108 can only move one card to be printed out of the card storage slot at a time. In some embodiments, the card slot further comprises a card outlet (not shown) formed on one side of the card slot, the size of the card outlet in the vertical direction is matched with the thickness of one card to be printed, and the card to be printed is moved out of the card slot from the card outlet. In some preferred embodiments, the size of the card outlet in the vertical direction can be flexibly adjusted, so that the card outlet requirements of cards with various thicknesses can be met.

Introduction of read-write card device

While the above is only briefly described with respect to the card reader/writer device 20, fig. 6 to 9 show the specific structure of the card reader/writer device 20 in some embodiments, and the card reader/writer device 20 will be described in detail with reference to fig. 6 to 9.

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 driving mechanism. Wherein:

the card reading and writing rack comprises a first card reading and writing side plate 202 and a second card reading and writing side plate 203 which are vertically and oppositely arranged, and a reading and writing channel for a card to be printed to pass through is formed between the first card reading and writing side plate 202 and the second card reading and writing side plate 203. The card reading and writing module 201 is connected to the card reading and writing rack and located above the reading and writing channel. The card reading and writing driving mechanism is used for driving the card to be printed to pass through the reading and writing channel so as to realize the reading or writing of the card to be printed by the card reading and writing module 201.

In some embodiments, the read/write card driving mechanism includes at least two sets of read/write card driving wheel sets disposed in the read/write channel, and a read/write card gear driving structure disposed on an outer wall of the first read/write card side plate 202 or the second read/write card side plate 203 for driving the at least two sets of read/write card driving wheel sets to rotate. The card reading and writing transmission wheel set comprises a first card reading and writing transmission wheel and a second card reading and writing transmission wheel, and a gap is formed between the first card reading and writing transmission wheel and the second card reading and writing transmission wheel for the card to be printed to pass through. The card reading and writing gear transmission structure is used for driving the first card reading and writing transmission wheel or the second card reading and writing transmission wheel of each card reading and writing transmission wheel set to rotate so as to drive a card to be printed to enter and penetrate through a gap between the first card reading and writing transmission wheel and the second card reading and writing transmission wheel. Preferably, the width of the read-write channel is matched with the width of an identification card to be printed, and the size of the gap between the first read-write card driving wheel and the second read-write card driving wheel is matched with the thickness of the identification card to be printed.

In some embodiments, the first card driving wheel of the card driving wheel set is a driving wheel, and the second card driving wheel is a driven wheel. Namely: the read-write card gear transmission mechanism is only connected with the first read-write card transmission wheel and drives the first read-write card transmission wheel to rotate. When the card to be printed enters the gap in the read-write card transmission wheel set, the first read-write card transmission wheel serving as the driving wheel can drive the second read-write card transmission wheel serving as the driven wheel to rotate reversely under the driving of friction of the card, so that the card is driven to pass through the gap between the first read-write card transmission wheel and the second read-write card transmission wheel.

In other embodiments, the second card driving wheel of the card driving wheel set is a driving wheel, and the first card driving wheel is a driven wheel. Namely: the read-write card gear transmission mechanism is only connected with the second read-write card transmission wheel and drives the second read-write card transmission wheel to rotate. When the card to be printed enters the gap in the read-write card transmission wheel set, the second read-write card transmission wheel serving as the driving wheel can drive the first read-write card transmission wheel serving as the driven wheel to rotate reversely under the driving of friction of the card, so that the card is driven to pass through the gap between the second read-write card transmission wheel and the first read-write card transmission wheel.

In some embodiments, the card gear transmission mechanism includes a card driving gear and at least two card driven gears corresponding to the at least two card driving gear sets one by one, the card gear transmission mechanism and each card driven gear are connected by a card belt, and each card driven gear rotates with the first card driving gear or the second card driving gear of the corresponding card driving gear set through a transmission shaft.

When the card driving gear rotates, the card driving gear can synchronously drive the card driven gears to rotate so as to drive the first card driving wheel or the second card driving wheel of each card driving wheel set to rotate, so that cards are driven to sequentially pass through a gap between the first card driving wheel and the second card driving wheel of each card driving wheel set so as to pass through the card reading and writing device.

It can be seen that the gap in each of the read/write card transmission wheel sets forms an identification card transmission channel in the read/write card device 20. The card to be printed passes through the card reading and writing transmission wheel set in sequence so as to pass through the card reading and writing device 20. Specifically, the gap in the set of the read/write card transmission wheel set near one end of the read/write card device 20 forms a feeding port of the read/write card device 20, and the gap in the set of the read/write card transmission wheel set near the other end of the read/write card device 20 forms a discharging port of the read/write card device 20.

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

Referring to fig. 7, in some embodiments, the card reading/writing device 20 of the present invention includes two sets of the card reading/writing transmission wheel sets, wherein: one set of the read/write card transmission wheel set is located at one end of the read/write card device 20 to form a feeding port of the read/write card device 20, and the other set of the read/write card transmission wheel set is located at the other end of the read/write card device 20 to form a discharging port of the read/write card device 20. The two read/write card transmission wheel sets each comprise a first read/write card transmission wheel 207 and a second read/write card transmission wheel 208.

The card reading and writing gear transmission mechanism comprises a card reading and writing driving gear 204 and two card reading and writing driven gears 205 arranged on the first card reading and writing side plate 202, the card reading and writing driving gear 204 and the two card reading and writing driven gears 205 are connected through a card reading and writing belt 206, and the two card reading and writing driven gears 205 are respectively connected with a first card reading and writing transmission wheel 207 of the corresponding card reading and writing transmission wheel set through a transmission shaft (not shown) penetrating through the first card reading and writing side wall 202.

The card to be printed enters the card reading and writing device 20 through one set of card reading and writing transmission wheel set and moves forward under the driving of the card reading and writing transmission wheel set to accept the operation of reading or writing the card, and the card to be printed after the card reading or writing is finished leaves the card reading and writing device 20 through the other set of card reading and writing transmission wheel set.

In some embodiments, the card reading and writing device 20 further includes a card reading driving motor (not shown) connected to the card reading driving gear 204, and the card reading driving motor is configured to drive the card reading driving gear 204 to rotate.

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

In addition, in order to trigger the card reading/writing module 201 to perform a card reading/writing operation, in some embodiments, the card reading/writing device 20 further includes a position sensor (not shown) disposed below the card reading/writing module 201, when the card to be printed enters the card reading/writing device 20 and reaches a predetermined position, the position sensor is triggered to generate a sensing signal, and the card reading/writing module 201 performs the card reading/writing operation after receiving the sensing signal.

As mentioned above, the forward-backward turning means that the turning mechanism turns the current printing surface of the identification card from the first printing surface to the second printing surface in the direction parallel to the translation direction of the identification card, and after the forward-backward turning, the type of the current printing surface changes, and the direction remains unchanged.

As shown in fig. 10 to 13, in some embodiments, the printer stage 30 includes a stage frame, a turning support disposed on the stage frame, and a turning driving mechanism. Wherein:

Wherein: a through hole is formed in the first machine table side plate 317, and the end of the inner side of the turnover driven gear 302 passes through the through hole and extends inwards 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.

The first turning side plate 308 of the turning bracket is connected to the inner end of the turning driven gear 302 and can rotate with the turning driven gear 302, and the second turning side plate 315 of the turning bracket is connected to the rotating shaft 314 and can rotate around the rotating shaft 314. When the overturning driving gear 301 drives the overturning driven gear 302 to rotate through the overturning belt 303, the overturning bracket overturns back and forth along with the overturning driven gear 302.

When the identification card to be turned over is positioned on the turning support and the central axis of the identification card is coaxial with the rotating shaft 314, the turning driving mechanism drives the turning support to rotate so as to realize 180-degree in-situ turning of the identification card. In the in-situ turnover process, the central axis of the identification card is always coaxial with the rotating shaft 314, so that after the in-situ turnover, the current printing surface of the identification card is turned over from the first printing surface to the second printing surface, and the position of the identification card on the printer table is kept unchanged.

It can be seen that the installation axis of the rotating shaft 314 forms the central axis of the preset printing position, when the central axis of the identification card is coaxial with the rotating shaft 314, the identification card reaches the preset printing position, at this time, the continuous printing on two printing surfaces of the identification card can be realized by turning over the identification card, and the position of the identification card in the horizontal direction does not need to be adjusted in the printing process.

The overturning driving mechanism further comprises an overturning driving motor 319 connected with the overturning driving gear 301, and the overturning driving motor 319 is used for driving the overturning driving gear 301 to rotate. In some embodiments, the first machine side plate 317 is provided with a flip driving motor mounting opening corresponding to the position of the flip driving gear 301, and the flip driving motor 319 penetrates through the flip driving motor mounting opening.

In order to fix both sides of the card and push the card to translate on the overturning bracket to reach or leave a preset printing position. In some embodiments, as shown in fig. 12 and 13, the printer stage 30 further includes:

the translation transmission wheel sets are axially arranged on the first overturning side plate 308 and comprise a first translation transmission wheel 309 and a second translation transmission wheel 310, and a translation gap is formed between the first translation transmission wheel 309 and the second translation transmission wheel 310 so as to clamp one side of the certificate card and drive the certificate card to translate on the overturning bracket.

And the translation driving mechanism is arranged on the outer side of the machine table rack and is used for driving 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 overturning bracket.

It can be seen that the translation transmission wheel set, the translation guide groove 316 and the translation driving mechanism constitute a translation mechanism of the printer platform 30, which can drive the certificate card to translate on the turnover support.

In some embodiments, the translation drive mechanism further includes a translation drive gear 304, a translation driven gear set. Wherein: the translational driving gear 304 is disposed on an outer wall of the first machine side plate 317, the translational driven gear set is disposed on an outer end of the turning driven gear 302, the translational driven gear set includes a first translational driven gear 305 and at least two second translational driven gears 307 linked with the first translational driven gear 305, wherein: the first translational driven gear 305 is disposed at the center of the outer end of the turning driven gear 302, the translational driving gear 304 is connected with the first translational driven gear 305 through a translational belt 306, and the at least two second translational driven gears 307 are connected with the at least two sets of translational transmission gear sets in a one-to-one correspondence manner.

In some embodiments, at least two transmission rods corresponding to the at least two second translation driven gears are inserted into the turning driven gear 302, one end of each transmission rod is connected to one second translation driven gear 307, and the other end of each transmission rod is connected to the first translation transmission wheel 309 or the second translation transmission wheel 310 of one set of translation transmission wheel sets.

When the translation driving gear 304 drives the first translation driven gear 305 to rotate through the translation belt 306, the first translation driven gear 305 drives each second translation driven gear 307 to synchronously rotate, and each second translation driven gear 307 drives the first translation driving wheel 309 or the second translation driving wheel 310 of each translation driving wheel set to synchronously rotate through the connecting rod.

In some embodiments, the first translational driven gear 309 of the translational transmission wheel set is a driving wheel, and the second translational driven gear 310 of the translational transmission wheel set is a driven wheel, i.e. the second translational driven gear 307 is connected with the first translational driven gear 309 of the translational transmission wheel set. When the card to be printed enters the gap in the translation transmission wheel set, under the driving of the friction of the card, the first translation driven gear 309 serving as a driving wheel can drive the second translation driven gear 310 serving as a driven wheel to rotate reversely, so that one side of the card is driven to pass through the translation gap between the first translation driven gear 309 and the second translation driven gear 310 to translate horizontally, and synchronously, the other side of the card translates horizontally along the translation guide groove 316.

The utility model discloses the seventh aspect provides an automatic

play card device

The automatic card discharging device 40 comprises at least two card discharging transmission wheel sets and a card discharging gear transmission mechanism for driving the at least two card discharging transmission wheel sets to rotate, each card discharging transmission wheel set comprises a first card discharging transmission wheel and a second card discharging transmission wheel, and a gap is formed between the first card discharging transmission wheel and the second card discharging transmission wheel for a card to pass through.

It can be seen that the gap in each card output transmission wheel set forms an identification card conveying channel in the automatic card output device 40. The printed identification card passes through each card discharging transmission wheel set in sequence so as to pass through the automatic card discharging device 40. Particularly, the gap in the group of the card discharging transmission wheel set near one end of the automatic card discharging device 40 forms a feeding hole of the automatic card discharging device 40, and the gap in the group of the card discharging transmission wheel set near the other end of the automatic card discharging device 40 forms a discharging hole of the automatic card discharging device 40.

In some embodiments, the automatic card discharging device 40 of the present invention comprises two sets of the card discharging transmission wheel sets, wherein: one group of the card discharging transmission wheel sets is positioned at one end of the automatic card discharging device 40 to form a feeding hole of the automatic card discharging device 40, and the other group of the card discharging transmission wheel sets is positioned at the other end of the automatic card discharging device 40 to form a discharging hole of the card discharging device. The two card-discharging transmission wheel sets each include a first card-discharging transmission wheel (not shown) and a second card-discharging transmission wheel 404.

Correspondingly, the card discharging gear transmission mechanism comprises a card discharging driving gear 401 and two card discharging driven gears 402, the card discharging driving gear 401 and the two card discharging driven gears 402 are connected through a card discharging belt 403, and the two card discharging driven gears 402 are respectively connected with the first card discharging transmission wheels of the corresponding card discharging transmission wheel sets through a transmission shaft.

The printed card enters the automatic card discharging device 40 through one card discharging transmission wheel set, moves forward under the driving of the card discharging transmission wheel set, and finally leaves the card reading and writing device 20 through the other card discharging transmission wheel set.

In some embodiments, the automatic card discharging device 40 further includes a card discharging driving motor connected to the card discharging driving gear 401, and the card discharging driving motor is configured to drive the card discharging driving gear 401 to rotate.

In order to facilitate understanding of the present invention, the operation of the non-shielding certificate card photographing device shown in fig. 18 to 21 will be described in detail.

When the identification card 100 needs to be translated to the pre-photographing position, the first translation upper driving wheels 931 and the second translation upper driving wheels 933 are in the initial positions. A plurality of first translation upper driving wheels 931 are arranged perpendicular to the card direction, and a translation gap is formed between each first translation upper driving wheel 931 and the corresponding first translation lower driving wheel 932 so as to clamp one side of the card 100 and drive the card to translate; a plurality of second translation upper transmission wheels 933 are arranged in a direction perpendicular to the card direction, and a translation gap is formed between each second translation upper transmission wheel 933 and the corresponding second translation lower transmission wheel 934 so as to clamp the other side of the card 100 and drive the card to translate. At this point, the translating

upper drive wheels

931, 933 and translating

lower drive wheels

932, 934 act to transport the identification card 100.

When the card 100 is translated to a preset photographing position along the transmission channel 921 and needs to photograph, the third rotating shaft 923 rotates in the second rotating direction, the third gear 9232 and the first gear 9212 drive the first rotating shaft 921 to rotate, so that the plurality of first translating upper transmission wheels 931 turn over to the photographing position, and the fourth gear 9234 and the second gear 9222 drive the second rotating shaft 922 to rotate, so that the plurality of second translating upper transmission wheels 933 turn over to the photographing position. A plurality of first translating upper drive wheels 931 positioned parallel to the identification card direction such that the plurality of first translating upper drive wheels 931 avoid the identification card 100; a plurality of second translating upper drive wheels 933 are positioned parallel to the identification card orientation such that the plurality of second translating upper drive wheels 933 clear the identification card 100. That is, when the card at a predetermined photographing position needs to be photographed, the plurality of first translational upper drive wheels 931 and the plurality of second translational upper drive wheels 933 are turned on. At this point, the baffle 942 enters the photoelectric sensor 944, and the sensor 940 generates and outputs a roll-to-bit signal. Subsequently, the card 100 located at the pre-photographing position is photographed by the photographing camera 91 located above the photographing housing 910.

When the card 100 needs to be translated to leave the predetermined photographing position after photographing is completed, the third rotating shaft 923 rotates in a first rotating direction (the first rotating direction is opposite to the second rotating direction), the third gear 9232 and the first gear 9222 drive the first rotating shaft 921 to rotate, so that the first translation upper transmission wheels 931 are turned to the initial position, and the fourth gear 9234 and the second gear 9222 drive the second rotating shaft 922 to rotate, so that the second translation upper transmission wheels 933 are turned to the initial position. That is, when the card needs to be translated to reach or leave the predetermined photographing position, the number of first translation upper driving wheels 931 and the number of second translation upper driving wheels 933 are reset (or closed). Subsequently, the translation module 930 sends out the identification card 100 in the original direction or the reverse direction.

The operation of the non-blocking identification card photographing device 90 of the laser printing system is described below.

In the case of single-sided printing, the preceding printing step refers to the laser printing method described above. When the identification card 100 is conveyed to the non-shielding identification card photographing device 90, the rotation shaft driving motor 926 operates, the rotation shaft driving wheel 924 on the edge drives the rotation shaft at one end of the third rotation shaft 923 to drive the driven wheel 925 to rotate, the third rotation shaft 923 drives the third gear 9232 and the fourth gear 9234 on the two ends of the third rotation shaft 923 to rotate, the third gear 9232 and the fourth gear 9234 respectively drive the first gear 9212 and the second gear 9222 to rotate, the first rotation shaft 921 and the second rotation shaft 922 rotate outwards to open the first translation upper driving wheel 931 and the second translation upper driving wheel 933 along with the rotation of the first gear 9212 and the second gear 9222, the first translation upper driving wheel 931 and the second translation upper driving wheel 933 are changed from the original direction perpendicular to the identification card 100 to the direction parallel to the identification card 100, the photographing is performed by the photographing camera 91, after the photographing is completed, the first translation upper driving wheel 931 and the second translation upper driving wheel 933 are restored to the initial positions, the identification card 100 is transported out in the original direction.

When the double-sided printing is performed, after the single-sided printing is completed, the first translation upper driving wheel 931 and the second translation upper driving wheel 933 of the non-shielding photographing device 90 are restored to the initial positions again, the certificate card 100 is conveyed to the printer table 30 in the reverse direction to be turned over, after the turning over is completed, the steps are repeated, the non-shielding photographing is performed on the reverse side of the certificate card 100 again, and finally the certificate card 100 is conveyed out in the original direction.
