Description

Technical Field

[0001] The invention relates to the field of card processing, in particular to a card personalization production line. Background Art

[0002] UV printing is usually called DOD printing. With the continuous development of technology, DOD printing has become more and more popular in the printing industry. At present, it is basically divided into scanning printing mode in which the ink is gradually superimposed by multiple reciprocating movements of the nozzle and one-time printing mode in which the nozzle is fixed and the material moves. The one-time printing mode is more than ten times more efficient than the multiple printing mode, but because the clarity of the one-time printing mode is much different from that of the multiple printing mode, it is rarely used for high-precision and high-definition printing, especially for picture printing. Now the quality of one-time printing has been greatly improved. In addition to monochrome printing, multi-nozzle color mixing has also been successful in color printing. With the continuous expansion of market usage, the cost of DOD printing, including inkjet printers, has dropped significantly. Its development direction is how to improve the quality and efficiency of printing, save space and labor costs. In order to achieve high-quality printing, the material needs to move at a uniform, stable and accurate speed, and the multiple nozzles need to accurately control the inkjet flow and time. The latter is a technology that the inkjet printer itself needs to continuously improve.

[0003] The traditional material conveying method uses a conveyor belt for conveying. For example, the invention patent with application publication number CN118386690A discloses a "high-precision double-sided DOD printing device, method and production line for sheet materials". The high-precision double-sided DOD printing device for sheet materials conveys the sheet material of the upstream sheet material conveying device to the first positioning seat of the first mobile platform through the first conveying module. Before the sheet material is conveyed to the first positioning seat, the OCR module is used to capture the image of the sheet material, and the positioning data recording the position distribution of the image to be printed in the sheet material is prepared; at the same time, the position of the sheet material input to the first positioning seat is accurately positioned, and according to the prepared positioning data, the position of the first positioning seat in the Y-axis direction is accurately adjusted to make the position relationship between the sheet material and the image to be printed in the Y-axis direction correspond; the first servo drive mechanism drives the first positioning seat to move to the first surface printing module to perform printing processing on the first side of the sheet material; during the printing process, the first positioning seat The position seat moves along the X-axis direction, and by controlling the trigger time for starting printing, high-precision printing starting positioning in the X-axis direction is achieved; after completing the printing process on the first side of the sheet material, the first servo drive mechanism drives the first positioning seat to move to the flip module; the flip module flips the sheet material that has completed the first side processing and transfers it to the second positioning seat of the second mobile platform; and accurately locates the position of the sheet material in the second positioning seat and the position of the second positioning seat in the Y-axis direction; the second servo drive mechanism drives the second positioning seat to move to the second surface printing module to perform printing on the second side of the sheet material; during the printing process, the second positioning seat moves along the X-axis direction, and by controlling the trigger time for starting printing, high-precision printing starting positioning in the X-axis direction is achieved; after completing the printing process on the second side of the sheet material, the second servo drive mechanism drives the second positioning seat to move to the second transport module; the second transport module transports the sheet material that has completed the double-sided printing process to the downstream sheet material conveying device for subsequent processes.

[0004] In the process of double-sided printing of sheet materials by the above-mentioned high-precision double-sided DOD printing device for sheet materials, the first surface printing module and the second surface printing module are arranged in parallel, resulting in a large and uncompact equipment volume, and a large transfer stroke of the sheet material between the first positioning seat and the second positioning seat, which is time-consuming and affects the processing efficiency of the sheet material.

After completing the information writing, the upstream card conveying device 4 conveys the card to the end of the upstream card conveying device 4.

[0047] A second card flip module is disposed below the second OCR detection module 10;

[0048] When the card that has completed double-sided printing is conveyed to the bottom of the second OCR detection module 10 through the downstream card conveying device 13, the card is flipped by the second card flipping module arranged below the second OCR detection module 10, so that the second OCR detection module 10 detects the front and back sides of the card, the purpose of which is to detect whether the front and back sides of the card have completed printing and to detect the printing quality, so as to facilitate the subsequent collection of qualified and unqualified cards separately; at the same time, the second card flipping module located below the second OCR detection module 10 can flip the card so that the card faces up again; in this way, after the second side of the card is printed, there is no need to set up a flipping module 7 separately to flip it, which is conducive to reducing the manufacturing cost of the equipment.

[0052] The conveying driving mechanism 17 drives the mobile platform 16 to move to the first surface printing module 6, the flip module 7 and the second surface printing module 8 in sequence. The conveying driving mechanism 17 can be driven by a moving trolley, that is, the moving trolley drives the mobile platform 16 to move on the guide rail, thereby driving the mobile platform 16 to the first surface printing module 6, the flip module 7 and the second surface printing module 8;

[0053] In this embodiment, the mobile platform 16 is divided into two groups, namely the first mobile platform 16A and the second mobile platform 16B, wherein the first mobile platform 16A is used to transport the cards to be printed to the first surface printing module 6 and the flip module 7 in sequence, and the second mobile platform 16B is used to transport the flipped cards to the second surface printing module 8 and the end of the downstream card conveying device 13; correspondingly, the conveying drive mechanism 17 is also divided into two groups, namely the first conveying drive mechanism and the second conveying drive mechanism, wherein the first conveying drive mechanism is used to drive the first mobile platform 16A to move; the second conveying drive mechanism is used to drive the second mobile platform 16B to move.

[0054] See also Figure 1-Figure 13The mobile platform 16 is provided with a plurality of positioning grooves 14 arranged along the conveying direction of the card, and the mobile platform 16 is provided with a first positioning mechanism for positioning the card in a direction parallel to the conveying direction of the card and a second positioning mechanism for positioning the card in a direction perpendicular to the conveying direction, wherein the second positioning mechanism is a plurality of groups, and the plurality of groups of second positioning mechanisms are respectively arranged at the end of the upstream card conveying device 4 and the flip module 7.

[0055] Through the above-mentioned arrangement, when the first transport module 5 transports the card at the end of the upstream card conveying device 4 to the first mobile platform 16A, it is necessary to position the card located in the first mobile platform 16A, and correct the posture of the card in the X-axis and Y-axis directions by the first positioning mechanism and the second positioning mechanism, and then the first mobile platform 16A transfers the positioned card to the first surface printing module 6; similarly, after the first surface printing module 6 prints the first side of the card in the first mobile platform 16A, the first mobile platform 16A transports the card with the first side printing to the flip module 7, and the flip module 7 flips the card on the first mobile platform 16A 180 degrees, and then transfers it to the second mobile platform 16B. During this process, it is necessary to position the card transferred to the second mobile platform 16B to adjust the posture of the card on the second mobile platform 16B again; the second mobile platform 16B then transfers the card to the second surface printing module 8 to complete the printing of the second side of the card.

[0056] See also Figure 1-Figure 13 The first positioning mechanism includes a first fixed positioning member 161, a first movable positioning member 162 arranged opposite to the first fixed positioning member 161, and a first positioning driving mechanism for driving the first movable positioning member 162 to move in a direction opposite to the conveying direction of the card, wherein the first fixed positioning member 161 is fixed on the mobile platform 16; the first positioning mechanism includes a first positioning cylinder 166, the first positioning cylinder 166 is installed on the mobile platform 16, and the piston rod of the first positioning cylinder 166 is connected to the first movable positioning member 162; an avoidance groove is provided on the mobile platform 16 and on the first movable positioning member 162.

[0057] When the card needs to be positioned in the X-axis direction, the first positioning cylinder 166 drives the first movable positioning member 162 to move toward the direction of the first fixed positioning member 161, thereby realizing the positioning of the card in the X-axis direction; in order to ensure the movement accuracy of the first movable positioning member 162, a sliding mechanism is arranged between the first movable positioning member 162 and the mobile platform 16, such as a slide rail arranged on the mobile platform 16 and a slider arranged on the slide rail; the first movable positioning member 162 is installed on the slider.

[0062] The second positioning drive mechanism includes a lifting rod 165 disposed at the bottom of the fixed frame and a lifting cylinder 167 for driving the lifting rod 165 to move up and down, wherein the lifting rod 165 extends along the conveying direction of the card; the lifting cylinder 167 drives the lifting rod 165 to move upward, so as to cause the lifting rod 165 to push up the driving wheel 1643, thereby causing the positioning rod 1641 at the upper end of the rotating frame 1642 to swing outward;

[0063] When it is necessary to position the card in the positioning slot 14 in the Y-axis direction, the lifting cylinder 167 drives the lifting rod 165 to move downward, so that the lifting rod 165 is separated downward from the driving wheel 1643 on the rotating frame 1642, and under the gravity of the rotating frame 1642 itself or through the elastic force of the torsion spring arranged between the rotating frame 1642 and the fixed frame, the positioning rod 1641 swings toward the direction of the second fixed positioning member 163, thereby pushing the card to move in the direction of the second fixed positioning member 163, and when the card contacts the second fixed positioning member 163, the positioning of the card in the Y-axis direction is completed.

[0064] See also Figure 1-Figure 13 , a plurality of groups of air holes 15 are arranged in the positioning groove 14, and the plurality of groups of air holes 15 are connected to the negative pressure device; when the first positioning mechanism and the second positioning mechanism are positioning the card, the negative pressure device is not started; and when the card is positioned, the negative pressure device is started, so that negative pressure is generated in the positioning groove 14, so that the card is adsorbed in the positioning groove 14, so as to prevent the position displacement of the card during transportation and printing; when the flipping module 7 flips the card that has completed the printing on the first side and the second transporting module 9 transports the card on the second mobile platform 16B to the downstream card conveying device 13, the negative pressure device will stop working to facilitate the flipping and transfer of the card.

[0065] See also Figure 1-Figure 13 The first conveying module 5 and the second conveying module 9 have the same structure, including a conveying frame, a plurality of conveying components arranged on the conveying frame, a lifting and conveying driving mechanism for driving the conveying components to perform lifting and lowering movements, and a transverse conveying driving mechanism for driving the conveying components to move along a direction perpendicular to the conveying direction of the card, wherein the conveying component is a suction nozzle; the lifting and conveying driving mechanism and the transverse conveying driving mechanism can be driven by a cylinder or an electric push rod; or, the first conveying module 5 and the second conveying module 9 in this embodiment can also be implemented by an existing conveying device.

[0066] See also Figure 1-Figure 13 The flip module 7 includes a mobile frame 711, a plurality of clamping flipping mechanisms arranged on the mobile frame 711, and a moving driving mechanism for driving the mobile frame 711 to move along a direction perpendicular to the conveying direction of the card, wherein:

[0068] In addition, during flipping, the first mobile platform 16A first transports multiple cards to the flipping station, and the clamping mechanisms in the multiple clamping and flipping mechanisms clamp the multiple cards in the first mobile platform 16A at the same time and flip them. During the flipping process, the first mobile platform 16A leaves the flipping station, and at the same time, the second mobile platform 16B moves to the flipping station, and then the clamping mechanisms in the multiple clamping and flipping mechanisms flip the multiple cards 180° and drop them into the second mobile platform 16B; by utilizing the time for the clamping and flipping mechanisms to flip the cards, the first mobile platform 16A can quickly leave and the second mobile platform 16B can quickly reach the card receiving position, so that the time for flipping and handing over the cards is as compact as possible, the time for flipping and handing over the cards is shortened to the greatest extent, and the production efficiency is improved.

[0069] In addition, before flipping, the clamping mechanism is located on the side close to the second surface printing module 8, and after flipping, it is located on the side close to the first surface printing module 6.

Before the card is transported to the first mobile platform 16A, the first OCR detection module 2 has been used to capture the image of the card, and the nesting data recording the position distribution of the image to be printed in the card has been prepared; at the same time, the position of the card input on the first mobile platform 16A is accurately positioned, and according to the prepared nesting data, the position of the first mobile platform 16A in the Y-axis direction is accurately adjusted so that the position relationship between the card and the image to be printed in the Y-axis direction corresponds;

[0082] Next, the first conveying driving mechanism 17 drives the first movable platform 16A to move to the first surface printing module 6 to perform printing on the first side of the card; after the printing on the first side of the card is completed, the first conveying driving mechanism 17 drives the first movable platform 16A to move to the flip module 7;

[0083] Then, the flip module 7 flips the card that has completed the first side processing and transfers it to the second mobile platform 16B; and accurately locates the position of the card in the second mobile platform 16B;

[0084] Then, the second conveying drive mechanism 17 drives the second mobile platform 16B to move to the second surface printing module 8 to print the second side of the card; after completing the printing process on the second side of the card, the second conveying drive mechanism 17 drives the second mobile platform 16B to move to the second handling module 9; the second handling module 9 transports the card that has completed the double-sided printing process to the downstream card conveying device 13 for subsequent processes.
