[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The directional terms mentioned in this invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this invention, and are not intended to limit this invention.

[0036] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Existing UV printing platforms are limited in scope and cannot print cards of different sizes in the same system. The entire platform structure needs to be replaced to achieve the printing of different sized cards. This results in excessively long replacement times, affecting certificate production efficiency and increasing economic costs.

[0039] The following is a preferred embodiment of a multi-card compatible printing platform and its usage method provided by the present invention, which can solve the above technical problems.

[0040] A preferred embodiment of the present invention provides a multi-card compatible printing platform. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The multi-card compatible printing platform includes multiple card holders and at least two sets of adjustable connectors 12. The card holders are used to position cards 100, and the multiple card holders are arranged along a first direction. Each set of adjustable connectors 12 includes multiple adjustable connectors 12, and each adjustable connector 12 is detachably connected between two adjacent card holders. The spacing between the adjacent card holders connected by the adjustable connectors 12 in the first direction is adjustable. When different adjustable connectors 12 are replaced between adjacent card holders, the multiple card holders can position cards 100 of different sizes, such as small cards of different sizes. Figure 1 In the diagram, the x-direction is the first direction, and the y-direction is the second direction.

[0041] The multi-card compatible printing platform of the present invention has one card 100 per card holder. Adjacent card holders can be movably connected via adjustable connectors 12. Pushing the card holder reduces the gap between card holders in different groups, allowing cards 100 to be placed one by one or in batches on each card holder, with the cards 100 touching each other. Pushing the card holder in the opposite direction increases the gap between adjacent card holders, separating and spacing adjacent cards 100. This spacing allows each card 100 to be independently identified and positioned, facilitating printing. When the adjustable connectors 12 in different sleeves are replaced between adjacent card holders, multiple card holders can position cards 100 of different sizes. The multi-card compatible printing platform of the present invention can print cards 100 of different sizes quickly and conveniently, improving work efficiency and saving time and economic costs.

[0042] Please refer to Figure 1 and Figure 2 Each set of card holders includes one card holder, meaning each card holder holds one card 100. At least one of two adjacent card holders is clearance-fitted with one set of adjustable connectors 12 in the first direction. This structure facilitates adjustment of the gap between two adjacent card holders, and is simple in structure and easy to operate.

[0043] Please refer to Figure 1 and Figure 4 The multi-card compatible printing platform also includes at least two covers 15, each cover 15 corresponding to a set of adjustable connectors 12. The covers 15 are detachably mounted on multiple card holders. Each cover 15 has multiple openings 151 along a first direction, the number of openings 151 corresponding to the number of card holders. The openings 151 allow the cards 100 to contact the card holders. The area between two adjacent openings 151 on the cover 15 is located below the gap between two adjacent cards 100. By blocking the gap between two adjacent cards 100 through the area between two adjacent openings 151 on the cover 15, ink can be prevented from flowing down from the gap between the two cards 100.

[0044] Please refer to Figure 2 In the first direction, one end of the card holder 11a is fixedly disposed, while the remaining card holders 11b are slidably disposed along the first direction. The multi-card compatible printing platform also includes an elastic element 13 connected to the card holders 11b at the other end of the first direction, providing elastic force so that all sliding card holders 11b move away from the fixed card holder 11a. Without external force, the elastic element 13 can drive all sliding card holders 11b to move away from the fixed card holder 11a, creating a gap between adjacent cards 100 for ease of use. In this embodiment, the elastic element 13 is illustrated as a tension spring. In other embodiments, a power element such as a cylinder can be used to drive the sliding card holders 11b to move away from the fixed card holder 11a.

[0045] Please refer to Figure 2 The multi-card compatible printing platform also includes a pusher block 14, which is connected to the card holder 11b at the other end of the first direction. Pushing the pusher block 14 moves all the sliding card holders 11b toward the positioned card holder 11a, which can reduce the distance between each group of card holders, making it easier to load the cards 100 and make the cards 100 connect with each other.

[0046] Please refer to Figure 2 The multiple adjustable connectors 12 in the same set have at least two different sizes along the first direction. Figure 2 (Two types are illustrated in the diagram) to allow for at least two different sizes of gaps between the card holders. By selecting adjustable connectors 12 of different specifications within the same system, finer adjustment of the spacing between adjacent card holders can be achieved. This allows the platform to more accurately adapt to the positioning requirements of cards 100 of specific sizes, improves the flexibility and applicability under the same printing mode, and further optimizes the matching accuracy with the card 100.

[0047] Please refer to Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 The multi-card compatible printing platform of this embodiment also includes at least one set of positioning connectors 16. A single set of positioning connectors 16 includes multiple positioning connectors 16, and each group of card holders includes at least two card holders. Two adjacent card holders within a group are detachably and fixedly connected by the positioning connectors 16. In this embodiment, each group of card holders is illustrated to include two card holders.

[0048] Each card slot group consists of at least two card slots detachably and fixedly connected by positioning connectors 16, forming a complete unit. This structure allows a group of card slots to collectively carry a single card 100 as a unit, thus accommodating cards 100 larger than small cards, such as large or medium cards. The spacing between groups is still adjusted by adjustable connectors 12. This structure allows the same printing platform to support a "small card" printing mode where a single card slot operates independently, using only the adjustable connectors 12. By changing the corresponding adjustable connectors 12 and positioning connectors 16, it can also support a "large card" or "medium card" printing mode where multiple card slots work together, expanding the platform's compatibility.

[0049] Please refer to Figure 5 , Figure 6 , Figure 9 and Figure 10 There are at least two sets of positioning connectors 16, and each set of positioning connectors 16 corresponds to a set of adjustable connectors 12. After replacing different sets of positioning connectors 16 and the corresponding set of adjustable connectors 12, multiple card holders can position cards 100 of different sizes. Figure 5 and Figure 6 The first set of positioning connectors 16 and the first set of adjustable connectors 12 are used to print large cards. Figure 9 and Figure 10 The second set of positioning connectors 16 and the second set of adjustable connectors 12 are used for printing medium-sized cards. With the above structure, the same printing platform can simultaneously print small, large, and medium-sized cards.

[0050] Please refer to Figure 6 and Figure 10 In the first direction, the length of a single positioning connector 16 in the first set of positioning connectors 16 is different from the length of a single positioning connector 16 in the second set of positioning connectors 16, so that the spacing between two adjacent card slots in a single set of card slots is different. Using the above structure, the intra-group spacing of the card slots can be precisely controlled to ensure accurate adaptation to the card 100.

[0051] Please refer to Figure 6 and Figure 10 In the first direction, the length of a single adjustable connector 12 in the first set of adjustable connectors 12 is different from the length of a single adjustable connector 12 in the second set of adjustable connectors 12, so that the spacing between adjacent card holders is different. Using this structure, the spacing between card holder groups can be precisely controlled to ensure accurate adaptation to the card 100.

[0052] In other embodiments, the length of a single positioning connector 16 in the first set of positioning connectors 16 may be different from the length of a single positioning connector 16 in the second set of positioning connectors 16, and the length of a single adjustable connector 12 in the first set of adjustable connectors 12 may be the same as the length of a single adjustable connector 12 in the second set of adjustable connectors 12. Alternatively, the length of a single positioning connector 16 in the first set of positioning connectors 16 may be the same as the length of a single positioning connector 16 in the second set of positioning connectors 16, and the length of a single adjustable connector 12 in the first set of adjustable connectors 12 may be different from the length of a single adjustable connector 12 in the second set of adjustable connectors 12.

[0053] Please refer to Figure 6 and Figure 10 In the two card holders connected to the same adjustable connector 12, at least one card holder has a clearance fit with the adjustable connector 12 in the first direction. This structure facilitates adjustment of the clearance between adjacent sets of card holders and is simple in design.

[0054] Please refer to Figure 6 and Figure 7 The card holder has a fixed connection structure 111 and a movable connection structure 112 on one side facing the adjacent card holder. The fixed connection structure 111 is used to connect the positioning connector 16, and the movable connection structure 112 is used to connect the adjustable connector 12. All fixed connection structures 111 are located on the same side of the second direction of all movable connection structures 112.

[0055] Please refer to Figure 6 and Figure 7 In this embodiment, card holder 11a has card holder 11b on only one side. Therefore, card holder 11a has a fixed connection structure 111 and a movable connection structure 112 only on the side facing card holder 11b. Card holder 11b in the middle position has other card holders on both sides, each with a fixed connection structure 111 and a movable connection structure 112. This structure allows the fixed connection structure 111 and the movable connection structure 112 to be in different positions. The positioning connector 16 and the adjustable connector 12 need to be installed in different positions in the second direction. When installing the positioning connector 16 and the adjustable connector 12 after determining the card holder group, it ensures that card holders within a group are connected by the positioning connector 16, and card holders between groups are connected by the adjustable connector 12, preventing incorrect installation. In this embodiment, there is only one card holder 11a, and the remaining card holders are card holders 11b. The second direction is perpendicular to the first direction. In other embodiments, the second direction may be distributed at an angle to the first direction.

[0056] In this embodiment, the fixed connection structure 111 and the movable connection structure 112 on both sides of the card holder are different, and therefore will be described separately. For example... Figure 7 As shown, the explanation will focus on the card holder 11b in the middle position. The side of the card holder 11b facing the first direction (i.e....) Figure 7 The fixed connection structure 111 and the movable connection structure 112 on the right side of the card holder 11b are respectively the first fixed connection structure 1111 and the first movable connection structure 1121. The first fixed connection structure 1111 is detachably fixedly connected to the positioning connector 16. The first movable connection structure 1121 is used for detachable fixed connection with the adjustable connector 12. The card holder 11b faces the other side of the first direction (i.e. Figure 7The fixed connection structure and the movable connection structure on the left side of the middle card holder 11b are the second fixed connection structure 1112 and the second movable connection structure 1122, respectively. The second fixed connection structure 1112 is used for detachable fixed connection with the positioning connector 16. The second movable connection structure 1122 is detachably clearance-fitted with the adjustable connector 12. The adjustable connector 12 is detachably fixedly connected to one set of card holders through the first movable connection structure 1121, and detachably clearance-fitted with another set of adjacent card holders through the second movable connection structure 1122. During the movement of the card holder 11b, the adjustable connector 12 will not detach from the card holder 11b. The positioning connector 16 can be fixedly connected to two adjacent card holders in the group through the first fixed connection structure 1111 and the second fixed connection structure 1112. In this embodiment, the first fixed connection structure 1111 and the first movable connection structure 1121 are both threaded holes, and the second fixed connection structure 1112 and the second movable connection structure 1122 are both cylinders, with the second fixed connection structure 1112 having a larger diameter than the second movable connection structure 1122.

[0057] In other embodiments, the card holders within a group may only have a fixed connection structure 111, while the card holders between groups may only have a movable connection structure 112. Alternatively, the card holders within a group may only have a fixed connection structure 111, while the card holders between groups may have both fixed connection structures 111 and movable connection structures 112. Another option is that the card holders within a group may have both fixed connection structures 111 and movable connection structures 112, while the card holders between groups may only have a movable connection structure 112.

[0058] A preferred embodiment of the present invention provides a method for using a multi-card compatible printing platform. The platform utilizes one set of adjustable connectors 12 to connect two adjacent card slots for printing cards of a first specification 100, such as a small card. By disassembling one set of adjustable connectors 12 and replacing it with another set to connect the two adjacent card slots, the spacing between the two sets of card slots in the first direction is adjusted for printing cards of a second specification 100, such as another small card.

[0059] Using one set of adjustable connectors 12 to connect two adjacent card holders, push the card holders to reduce the gap between the two adjacent card holders, place the card 100 on the card holder, push the card holders in the opposite direction to make the adjacent cards 100 move away, and print the first specification card 100.

[0060] Disassemble one set of adjustable connectors 12, replace it with another set of adjustable connectors 12 to connect the two adjacent card holders, push the card holders to reduce the gap between the two adjacent card holders, place the card 100 on the card holder, push the card holders in the opposite direction to make the adjacent cards 100 move away, and print the second specification card 100.

[0061] A preferred embodiment of the present invention provides another method for using a multi-card compatible printing platform. When there are at least two sets of positioning connectors 16, the first set of positioning connectors 16 connects two adjacent card slots within a group, and the first set of adjustable connectors 12 connects two adjacent groups of card slots for printing cards of a first specification 100, such as large cards. Alternatively, the first set of positioning connectors 16 and the first set of adjustable connectors 12 can be disassembled, and the second set of positioning connectors 16 can be replaced to connect two adjacent card slots within a group, adjusting the length of a single group of card slots in the first direction. The second set of adjustable connectors 12 can also be replaced to connect two adjacent groups of card slots, adjusting the spacing between the two adjacent groups of card slots in the first direction for printing cards of a second specification 100, such as medium cards.

[0062] A preferred embodiment of the present invention provides another method for using a multi-card compatible printing platform. The multi-card compatible printing platform utilizes one set of adjustable connectors 12 to connect two adjacent card slots for printing at least one type of card 100. One set of adjustable connectors 12 is disassembled and replaced with another set to connect the two adjacent card slots, adjusting the spacing between the two adjacent card slots in a first direction for printing at least one type of card 100. In this printing, at least one type of card 100 is different from the previous printing, and either the current printing of card 100 includes at least two different types, or the previous printing included at least two different types of card 100.

[0063] In other embodiments, multiple sizes of adjustable connectors 12 can be used simultaneously to print two or more sizes of small cards. Alternatively, multiple sizes of adjustable connectors 12 and multiple sizes of positioning connectors 16 can be used simultaneously to print two or more sizes of larger cards 100.

[0064] For example, before replacing the adjustable connector 12 and positioning connector 16 with a different specification, the positioned cards are all small cards. After replacing the adjustable connector 12 and positioning connector 16 with a different specification, the positioned cards are small and medium cards; or, after replacing the adjustable connector 12 and positioning connector 16 with a different specification, the positioned cards are small and large cards; or, after replacing the adjustable connector 12 and positioning connector 16 with a different specification, the positioned cards are medium and large cards; or, after replacing the adjustable connector 12 and positioning connector 16 with a different specification, the positioned cards are small, medium, and large cards.

[0065] The multi-card compatible printing platform and its usage method of the present invention allow each card holder to carry one card 100. Adjacent card holders can be movably connected via adjustable connectors 12. Pushing the card holders reduces the gap between card holders in different groups, allowing cards 100 to be placed one by one or in batches on each card holder, with the cards 100 touching each other. Pushing the card holders in the opposite direction increases the gap between adjacent card holders, separating and spacing adjacent cards 100. This spacing allows each card 100 to be independently identified and positioned, facilitating printing. When the adjustable connectors 12 in different sleeves are replaced between adjacent card holders, multiple card holders can position cards 100 of different sizes. The multi-card compatible printing platform of the present invention can print cards 100 of different sizes quickly and conveniently, improving work efficiency and saving time and economic costs.

[0066] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be covered within the scope of protection of the present invention.
