[0051] First, it should be noted that in the embodiments of this application, the length direction of the support is taken as the left-right direction, and the width direction of the support is taken as the front-back direction.

[0052] like Figures 1-8 As shown, the laser etching anti-counterfeiting printing device for booklet-style identification documents includes: a booklet feeding station, a card reading station, and a printing station arranged sequentially along a straight line; the booklet feeding station is equipped with a booklet feeding mechanism 100 and a booklet pushing mechanism 200, and the booklet feeding bracket of the booklet feeding mechanism 100 is equipped with a booklet feeding friction wheel 104, which is used to convey the booklet-style identification document from the booklet feeding station to the card reading station; the booklet pushing mechanism 200 is located below the booklet feeding bracket and can move the booklet-style identification document between the card reading station and the printing station; the card reading station is located above the booklet feeding mechanism 100 and is equipped with a reading and writing unit, which is mounted on the booklet feeding bracket; the printing station is equipped with a laser printing mechanism 300, which is located above the booklet feeding bracket and can perform laser etching printing on the booklet-style identification document at the printing station.

[0053] In the embodiment of the present application, the document feeding station, the reading and writing station and the printing station are arranged in sequence along the length direction of the document feeding support. The document is fed into the document feeding station, and after the chip information of the document is read by the reading and writing station, the document is sent to the printing station for laser etching printing. After printing, the document is sent from the printing station to the reading and writing station, and finally sent out from the document feeding station. The whole structure is compact, the space occupancy is low, and the arrangement is convenient, which greatly improves the flexibility of assembly and arrangement.

[0054] In the embodiment of the present application, the document feeding support has a fixed bottom plate 101 and a workbench plate 107. The workbench plate 107 is of a rectangular structure and is fixedly installed on the fixed bottom plate 101 through support columns 102. Specifically, the support columns 102 are four in number and are evenly distributed at the four corners of the rectangular workbench plate 107. The upper ends of the support columns 102 are detachably connected to the lower surface of the workbench plate 107, and the lower ends of the support columns 102 are detachably connected to the upper surface of the fixed bottom plate 101.

[0055] An intermediate mounting plate 106 is further arranged between the workbench plate 107 and the work bottom plate. The intermediate mounting plate 106 is of a rectangular structure that is adapted to the workbench plate 107. Three corners of the rectangular structure of the intermediate mounting plate 106 are detachably connected to three of the four support columns 102, and the corner not connected to the support column 102 is provided with a stepped structure. The stepped structure is missing from the inner side of the intermediate mounting plate 106, i.e. the corner of the rectangular structure of the intermediate mounting plate 106 not connected to the support column 102 is cut into a stepped structure to be equipped with other mechanisms or devices.

[0056] The document pushing mechanism 200 is detachably mounted on the upper surface of the intermediate mounting plate 106. Specifically, the document pushing mechanism 200 is detachably mounted on the upper surface of the intermediate mounting plate 106 through a plurality of parallelly arranged document pushing columns. The height of the document pushing columns can be adjusted according to the distance between the intermediate mounting plate 106 and the workbench plate 107, so that the upper end of the document pushing mechanism 200 is adapted to the card reading station and the printing station, and the document can be conveniently moved between the card reading station and the printing station.

[0057] In some optional embodiments, the document feeding friction wheels 104 are mounted on the ends of the upper surface of the document feeding support, and the document feeding friction wheels 104 are arranged in pairs. Specifically, two pairs of document feeding friction wheels 104 are arranged along the width direction of the document feeding support, and the two pairs of document feeding friction wheels 104 are mounted on the ends of the upper surface of the document feeding support through a friction wheel support 105. The two pairs of document feeding friction wheels 104 are linearly arranged along the width direction of the document feeding support.

[0058] In the embodiment of the present application, the friction wheel support 105 is a U-shaped structure, the two side plates of the U-shaped structure are fixedly installed at the end of the upper surface of the main support, and the pair of main friction wheels 104 are arranged in parallel in the inside of the U-shaped structure along the up-down direction, and the two ends of the main friction wheels 104 are rotatably connected with the two side plates of the U-shaped structure.

[0059] In some optional embodiments, the main feeding mechanism 100 further comprises a main feeding motor 103, which is installed on the main feeding support and below the main friction wheels 104, and is used to drive the main friction wheels 104 to rotate. Specifically, the main feeding motor 103 is installed on the upper surface of the middle installation plate 106 and is arranged close to the front end surface of the middle installation plate 106 along the front-rear direction.

[0060] In the embodiment of the present application, the main feeding motor 103 and the main friction wheels 104 are connected through belt transmission. Specifically, a driven pulley is coaxially installed at the outer side of one end of the rotating shaft of the main friction wheels 104, and a driving pulley is installed at the output end of the main feeding motor 103, and the driving pulley and the driven pulley are connected through a synchronous belt, so that the main feeding motor 103 drives the main friction wheels 104 to rotate, and the pair of main friction wheels 104 and the main type certificate are driven to move into or out of the main feeding station by the friction force. In this way, the main type certificate can be effectively moved into or out of the main feeding station, and the main feeding motor 103 is more flexible in arrangement because the belt transmission drives the friction force to rotate.

[0061] In some optional embodiments, the main pushing mechanism 200 comprises a main pushing motor 203 and a main pushing synchronous belt 201, the main pushing synchronous belt 201 is arranged along the extension direction of the main feeding station to the card reading station, and the outer surface of the main pushing synchronous belt 201 is provided with a pushing block; the main pushing motor 203 drives the main pushing synchronous belt 201 to move, so that the pushing block pushes the main type certificate to move between the card reading station and the printing station.

[0062] In the embodiment of the present application, on the one hand, the main pushing motor 203 is detachably installed on the middle installation plate 106 and drives the main pushing synchronous belt 201 to rotate through belt transmission, thereby improving the flexibility of arrangement of the main pushing motor 203 and the main pushing synchronous belt 201. On the other hand, the main pushing synchronous belt 201 is installed at the upper end of the main pushing support 202, and the workbench plate 107 is provided with a waist-shaped hole matched with the rotation of the main pushing synchronous belt 201, so that the pushing block arranged on the upper surface of the main pushing synchronous belt 201 can enter the waist-shaped hole during the rotation of the main pushing synchronous belt 201, thereby pushing the main type certificate to move between the card reading station and the printing station.

[0063] In a specific example, the two push-belt synchronous belts 201 are arranged in sequence along the extension direction of the card reading station to the printing station, and the coaxial connection is made at the joint end of the two push-belt synchronous belts 201. Specifically, the two push-belt synchronous belts 201 are fixedly installed on the middle mounting plate 106 through four groups of push-belt supports 202. Two groups of the four groups of push-belt supports 202 are respectively installed at the two ends of the upper surface of the middle mounting plate 106 along the length direction of the card feeding support, and the other two groups are correspondingly installed at the middle part of the upper surface of the middle mounting plate 106. The two push-belt synchronous belts 201 are respectively installed at the upper end of the two groups of push-belt supports 202. In this way, the push-belt motor 203 can drive the two push-belt synchronous belts 201 to rotate at the same time, thereby reducing the number of push-belt motors 203, improving the use efficiency of the push-belt motor 203, and ensuring the synchronization of the two push-belt synchronous belts 201, thereby avoiding the asynchronization of the two push-belt synchronous belts 201 when rotating, which may cause the movement of the card-type certificate between the card reading station and the printing station to be not coordinated.

[0064] In the embodiment of the present application, one group of push-belt supports 202 includes two push-belt columns, which are arranged side by side along the front-rear direction. The lower ends of the two push-belt columns are detachably installed on the middle mounting plate 106, and a rotating wheel is installed between the upper ends of the two push-belt columns. The rotating wheel is matched with the push-belt synchronous belt 201. A pulley matched with the output end of the push-belt motor 203 is arranged on the outside of one group of the four groups of push-belt supports 202.

[0065] In some optional embodiments, the push-belt mechanism 200 is arranged on the inner side of the card feeding support along the length direction of the card feeding support. Specifically, the push-belt mechanism 200 is located between the four card feeding columns and is detachably installed on the middle mounting plate 106. In this way, the structure of the push-belt mechanism 200 and the card feeding mechanism 100 is more compact, the space occupation of the card-type certificate laser etching and anti-fake printing device is reduced, and the device can be deployed in a small space.

[0066] In some optional embodiments, along the width direction of the card feeding support, one side of the read-write unit is installed on one side of the upper surface of the card feeding support through an antenna fixing piece 701, and the other side of the read-write unit is installed on the other side of the upper surface of the card feeding support through a connecting column. The width direction of the card feeding support is perpendicular to the extension direction of the card feeding station to the card reading station. Further, the antenna fixing piece 701 is a Z-shaped structure, and the lower end of the Z-shaped structure is connected with the upper surface of the card feeding support, and the upper end of the Z-shaped structure is connected with the read-write unit.

[0067] In the embodiment of the present application, along the width direction of the main body support, the two sides of the antenna mounting plate 702 of the read-write unit are detachably mounted on the upper surface of the main body support through the antenna fixing member 701 and the connecting column. The upper end and the lower end of the Z-shaped structure of the antenna fixing member 701 are provided with threaded holes or light holes, so as to connect the Z-shaped structure of the antenna fixing member 701 with the antenna mounting plate 702 and the main body support through bolts. The two ends of the connecting column are respectively provided with studs extending along the length direction of the connecting column. The stud at one end of the connecting column is screwed into the matching threaded hole on the upper surface of the main body support, and the other end is fixed by a nut after passing through the antenna mounting plate 702. Alternatively, the two ends of the stud are respectively provided with threaded holes extending along the length direction of the stud. The threaded hole at one end is screwed with the stud on the main body support, and the other end is screwed into the threaded hole of the matching screw through the bolt after passing through the antenna mounting plate 702, so as to press the antenna mounting plate 702.

[0068] In some optional embodiments, the laser printing mechanism 300 comprises a printing support 302 and a laser head 301. The printing support 302 is arranged across the main body support at the end opposite to the main body friction wheel 104. The laser head 301 is mounted on the printing support 302 and faces the printing station. Further, the laser head 301 is mounted on the printing support 302 through a printing lifting unit 303. The printing lifting unit 303 is fixedly mounted on the printing support 302 and can drive the laser head 301 to move up and down along the vertical direction. In this way, the printing flexibility of the laser head 301 during printing is improved, and the laser etching printing of the certificate is facilitated.

[0069] In the embodiment of the present application, the printing support 302 comprises two printing columns arranged side by side along the front-rear direction. The inner sides of the two printing columns can be mounted on the front and rear sides of the main body support, so as to detachably connect the laser printing mechanism 300 with the main body support.

[0070] In the embodiment of the present application, on the one hand, a column connecting rod is arranged between the two printing columns. The column connecting rod is provided with a moving slide rail. The printing lifting unit 303 is slidably connected to the moving slide rail, so that the printing lifting unit 303 can move along the front-rear direction, thereby driving the laser head 301 to move along the front-rear direction. On the other hand, the printing lifting unit 303 drives the laser head 301 to move up and down through a screw nut transmission mechanism. In this way, the working range of the laser head 301 is effectively improved, the position of the laser head 301 is adjusted, and the laser etching printing of the certificate is realized.

[0071] In the embodiment of the present application, the printing column can be in L-shaped structure, and the lower end of the L-shaped structure is detachably connected to the printing base plate.
