[0002] A UV printer is a printer that uses ultraviolet-curable ink. Generally, a UV printer is provided with a printing platform for placing a printing piece. Below the printing platform, there are a lifting drive assembly and a Y-axis drive assembly. The lifting drive assembly can drive the printing platform to lift, and the Y-axis drive assembly is used to drive the printing platform to move along the Y-axis. Above the printing platform, there is an X-axis drive assembly, and the X-axis drive assembly drives the print head to move along the X-axis direction. During printing, the lifting drive assembly, the Y-axis drive assembly, and the X-axis drive assembly cooperate to move to print the printing piece.

[0003] However, currently, the printing platform of a UV printer is usually not directly detachable. If it is necessary to replace different printing platforms for different printing pieces, multiple connecting components need to be disassembled to replace the printing platform. Therefore, traditional UV printers have the defects of cumbersome steps and inconvenient use when replacing the printing platform. Summary of the Utility Model

[0007] A bottom plate, and the printing platform is movably arranged on the bottom plate;

[0008] A Y-axis drive assembly, which is arranged on the bottom plate, and the Y-axis drive assembly is detachably drivingly connected to the connecting member; when the Y-axis drive assembly is drivingly connected to the connecting member, the drive assembly can drive the printing platform to move along the Y-axis direction; when the Y-axis drive assembly is separated from the connecting member, the printing platform can be disassembled;

[0009] And a guiding assembly, which is arranged on the bottom plate, the guiding assembly is slidably connected to the printing platform, and the guiding assembly extends along the Y-axis direction;

[0010] Wherein, the Y-axis drive assembly is detachably connected to the connecting member.

[0011] In a second aspect, a printer is provided, which includes a lifting mechanism, a nozzle mechanism, an X-axis driving mechanism, and the printing platform mechanism described in the above embodiments. The printing platform mechanism is installed on the lifting mechanism, the X-axis driving mechanism is disposed above the printing platform mechanism, a driving end of the X-axis driving mechanism is connected to the nozzle mechanism, the lifting mechanism is configured to drive the printing platform mechanism to move up and down along the Z axis, and the X-axis driving mechanism is configured to drive the nozzle mechanism to move along the X axis.

[0012] For the above printing platform mechanism and printer, by providing a Y-axis driving component and a printing platform on the bottom plate, and detachably slidingly connecting the printing platform and the bottom plate through a guiding component, the Y-axis driving component drives the printing platform to move along the Y axis. To facilitate the replacement of the printing platform, a connecting member is provided at the bottom of the printing platform, and the connecting member is detachably connected to the Y-axis driving component, and the guiding component is also detachably connected to the printing platform.

[0030] Refer to Figure 1 , Figure 1The exploded schematic diagram of the printing platform mechanism in an embodiment of the present application is shown. The printing platform mechanism provided in an embodiment of the present application can be used to place a printing piece on a UV printer. The printing platform mechanism includes a printing platform 100, a bottom plate 200, a Y-axis driving component 300, and a guiding component 400. The printing platform 100 is used to place the printing piece to be printed. The printing platform 100 is movably arranged on the bottom plate 200. Specifically, the Y-axis direction is set as the moving direction of the printing platform 100. The bottom plate 200 is used to be installed on the printer. A connecting piece 110 is provided at the bottom of the printing platform 100. Among them, the Y-axis driving component 300 is detachably connected to the connecting piece 110. The Y-axis driving component 300 is arranged on the bottom plate 200. The Y-axis driving component 300 is separably drivingly connected to the connecting piece 110. When the Y-axis driving component 300 is drivingly connected to the connecting piece 110, the Y-axis driving component 300 is used to drive the printing platform 100 to move along the Y-axis direction; when the Y-axis driving component 300 is separated from the connecting piece 110, the printing platform 100 can be disassembled. The guiding component 400 is arranged on the bottom plate 200. The guiding component 400 is slidably connected to the printing platform 100. The guiding component 400 extends along the Y-axis direction.

[0031] In the printing platform mechanism described in the embodiment of the present application, by arranging the Y-axis driving component 300 and the printing platform 100 on the bottom plate 200, and the printing platform 100 and the bottom plate 200 are detachably slidably connected through the guiding component 400, so as to define the sliding direction of the printing platform 100, and the Y-axis driving component 300 drives the printing platform 100 to reciprocate along the Y-axis. In order to facilitate the replacement of the printing platform 100, a connecting piece 110 is provided at the bottom of the printing platform 100. The connecting piece 110 is used to be detachably connected to the Y-axis driving component 300, and the guiding component 400 is also detachably connected to the printing platform 100. Thus, when the printing platform 100 needs to be replaced, the printing platform 100 can be directly disassembled by moving the printing platform 100, and then other printing platforms 100 can be replaced without disassembling the connecting components.

[0032] In the printing platform mechanism described in the embodiment of the present application, by setting the connection mode between the printing platform 100, the Y-axis driving component 300 and the bottom plate 200 as a detachable connection, when different printing platforms 100 need to be replaced, they can be directly disassembled or installed on the Y-axis driving component 300, which is convenient for printing different printing pieces by replacing different printing platforms 100, and has the advantages of simple operation and convenient use.

[0033] In an alternative embodiment, as Figure 1As shown, the guiding component 400 is provided with a guiding groove with openings at both ends along the Y-axis direction, and the printing platform 100 is provided with a sliding part along the Y-axis direction. The sliding part is slidably arranged in the guiding groove. When the sliding part is separated from the guiding groove through the openings at both ends, the printing platform 100 can be disassembled. In an exemplary embodiment, the guiding component 400 includes a first guiding member 410 and a second guiding member 420. The first guiding member 410 is installed at the bottom of the printing platform 100, and the second guiding member 420 is installed on the bottom plate 200. The first guiding member 410 and the second guiding member 420 are slidably and detachably connected, and the first guiding member 410 is movably clamped in the second guiding member 420. Through the guiding component 400, the movement of the printing platform 100 along the Y-axis direction can be limited, and the guiding component 400 is set as a detachable structure, which is convenient for replacing the printing platform 100 and improves the movement precision of the printing platform 100.

[0034] Embodiment 1

[0035] Combined with Figure 2 and Figure 3 as shown Figure 2 and Figure 3 show a schematic structural diagram of a printing platform mechanism in an embodiment of the present application. In some embodiments, the Y-axis driving component 300 includes a first driving unit 311 and a driving lead screw 313. The first driving unit 311 is installed on the bottom plate 200, and the driving lead screw 313 is rotatably installed on the bottom plate 200. The power output end of the first driving unit 311 is connected to the driving lead screw 313. Specifically, a first synchronous pulley 314 is provided at the power output end of the first driving unit 311, and a second synchronous pulley 315 is provided at one end of the driving lead screw 313. Through the first synchronous belt 312 sleeved on the first synchronous pulley 314 and the second synchronous pulley 315, the driving lead screw 313 can be driven to rotate after the first driving unit 311 is started. In this embodiment, the connecting member 110 includes a connecting body and a lead screw nut 111. The connecting body is fixedly installed on the side of the printing platform 100 close to the bottom plate 200 through a first fastener. The lead screw nut 111 is arranged on the connecting body and meshes with the driving lead screw 313, and the two are detachably connected, so that the lead screw nut 111 moves reciprocally under the rotation of the driving lead screw 313, thereby driving the printing platform 100 to move reciprocally. Specifically, the first fastener is a bolt or a screw. By setting the driving lead screw 313 and the lead screw nut 111 to be detachably meshed and connected, when the first driving unit 311 drives the driving lead screw 313 to rotate through the first synchronous belt 312, the lead screw nut 111 can be driven to move reciprocally on the driving lead screw 313. When the printing platform 100 needs to be disassembled and assembled, the lead screw nut 111 can be directly detached from the driving lead screw 313 for disassembly without additional operations to disconnect their connection, and the lead screw nut 111 can also be directly installed on the driving lead screw 313, which has the advantages of simple operation and convenient use.

[0036] For the guiding component 400 in this embodiment, as Figure 1 shown, the first guiding member 410 on one side of the printing platform 100 is set as a guiding shaft 411. The guiding shaft 411 is connected to the connecting body. A guiding sleeve 421 is installed on the bottom plate 200. The guiding sleeve 421 is provided with a guiding groove with openings at both ends. The guiding shaft 411 is slidably and detachably arranged in the guiding sleeve 421. When the printing platform 100 is disassembled, the guiding shaft 411 is separated from the guiding sleeve 421 through the openings at both ends. And the first guiding member 410 on the other side of the printing platform 100 is set as a guiding pulley 412. The guiding pulley 412 can directly slide on the bottom plate 200. When the printing platform is disassembled, the guiding pulley 412 directly detaches from the bottom plate 200. Through the first guiding member 410 and the second guiding member 420, the running stability of the printing platform 100 can be ensured, and the moving accuracy of the printing platform 100 can be improved.

[0037] Embodiment Two

[0038] In some other embodiments, the Y-axis driving component 300 includes a second driving unit and a turbine. The second driving unit is installed on the bottom plate 200. The turbine is rotatably arranged on the bottom plate 200. The power output end of the second driving unit is connected to the turbine. The second driving unit drives the turbine to rotate. In this embodiment, the connecting member 110 includes a connecting body and a worm. The connecting body is fixedly installed on one side of the printing platform 100 close to the bottom plate 200 through a second fastener. The worm is arranged on the connecting body, and the worm meshes with the turbine. The two are detachably connected, so that the worm reciprocates under the rotation of the turbine, thereby driving the printing platform 100 to reciprocate. Specifically, the second fastener is a bolt or a screw. By setting the turbine and the worm to be detachably meshed and connected, when the second driving unit drives the turbine to rotate, the worm reciprocates relative to the turbine. When the printing platform 100 needs to be disassembled and assembled, the screw can be directly detached from the turbine for disassembly without additional operations to disconnect their connection. The screw can also be directly installed on the turbine, which has the advantages of simple operation and convenient use.

[0039] In Embodiment Two, as Figure 3 shown, the guiding component 400 of the printing platform mechanism is the same as that of Embodiment One. The first guiding member 410 on one side of the printing platform 100 is set as a guiding shaft 411. The guiding shaft 411 is connected to the connecting body. A guiding sleeve 421 is installed on the bottom plate 200. The guiding sleeve 421 is provided with a guiding groove with openings at both ends. The guiding shaft 411 is slidably and detachably arranged in the guiding sleeve 421. When the printing platform 100 is disassembled, the guiding shaft 411 is separated from the guiding sleeve 421 through the openings at both ends. And the first guiding member 410 on the other side of the printing platform 100 is set as a guiding pulley 412. The guiding pulley 412 can directly slide on the bottom plate 200. When the printing platform is disassembled, the guiding pulley 412 directly detaches from the bottom plate 200.

[0040] Embodiment 3

[0041] In other embodiments, Figure 4 and Figure 5 As shown, the Y-axis driving assembly 300 includes a third driving unit 331 and at least one group of driving wheels arranged along the Y-axis direction, wherein the driving wheels include a first friction wheel 332 and a second friction wheel 333 arranged at intervals, and the third driving unit 331 is arranged on a side of the bottom plate 200 relative to the printing platform 100, and the third driving unit 331 drives at least one of the first friction wheel 332 or the second friction wheel 333 to rotate, wherein the first friction wheel 332 and the second friction wheel 333 rotate in opposite directions. In this embodiment, the connecting member 110 is a sliding rod 113, and the sliding rod 113 is detachably connected to the interval between the first friction wheel 332 and the second friction wheel 333, and the first friction wheel 332 and the second friction wheel 333 are used to drive the sliding rod 113 to move along the Y-axis direction.

[0042] Specifically, the first friction wheel 332 and the second friction wheel 333 are arranged along the X-axis direction, that is, the connecting line of the first friction wheel 332 and the second friction wheel 333 is perpendicular to the Y-axis, and the X-axis direction and the Y-axis direction are both parallel to the surface of the printing platform. The first friction wheel 332 is rotatably arranged on the upper surface of the bottom plate 200, and the second friction wheel 333 is rotatably arranged on the upper surface of the bottom plate 200. There is a gap between the first friction wheel 332 and the second friction wheel 333 along the X-axis direction, and the gap distance is designed according to the size of the sliding rod 113. In this embodiment, the driving wheels include three groups, and the three groups of driving wheels are arranged on the bottom plate 200 along the Y-axis. The sliding rod 113 is slidably inserted into the gap between each group of the first friction wheel 332 and the second friction wheel 333, and the two sides of the sliding rod 113 abut against the first friction wheel 332 and the second friction wheel 333 respectively. By detachably inserting the sliding rod 113 between the first friction wheel 332 and the second friction wheel 333, when the third driving unit 331 drives the first friction wheel 332 or the second friction wheel 333 to rotate, the sliding rod 113 can be driven to reciprocate along the Y axis. When the printing platform 100 needs to be disassembled, the sliding rod 113 can be directly disengaged from between the first friction wheel 332 and the second friction wheel 333. When the sliding rod 113 is disassembled, the connection between the two can be disconnected without additional operation. The sliding rod 113 can also be directly installed between the first friction wheel 332 and the second friction wheel 333, which has the advantages of simple operation and convenient use.

[0043] Furthermore, if Figure 5As shown, in order to ensure the power transmission of the third driving unit 331 to the first friction wheel 332, the third driving unit 331 further includes a motor, a second synchronous belt 334, a tension pulley 336 and a third synchronous pulley 335. The third synchronous pulley 335 is arranged on the bottom surface of the bottom plate 200, and the third synchronous pulley 335 is connected to the first friction wheel 332 in a one-to-one correspondence. The third synchronous pulley 335 and the first friction wheel 332 are coaxially arranged. A sliding groove 200A is provided on the bottom surface of the bottom plate 200. The sliding groove 200A is arranged along the X-axis at a position between the two third synchronous pulleys 335. The tension pulley 336 is movably arranged in the sliding groove 200A. The inner side of the second synchronous belt 334 is sleeved on the power output end of the motor and the third synchronous pulley 335. The motor is used to drive the second synchronous belt 334 to move, and the tension pulley 336 abuts against the outer side of the second synchronous belt 334. By arranging the third synchronous pulley 335 to connect the first friction wheel 332, the first friction wheel 332 can obtain power. Also, by arranging the tension pulley 336 in the sliding groove 200A, the situation where the tension pulley 336 presses against the second synchronous belt 334 can be adjusted, so as to adjust the tension of the second synchronous belt 334 on the third synchronous pulley 335, avoid slipping or failure of the power transmission between the motor and the third synchronous pulley 335, and ensure the stability of the power transmission.

[0044] Furthermore, the second friction wheel 333 is movably arranged on the bottom plate 200, and the second friction wheel 333 is also connected to an elastic member. The elastic member provides an elastic force for the second friction wheel 333 towards the first friction wheel 332. When the sliding rod 113 is inserted, the elastic member pushes the second friction wheel 333 to abut against the sliding rod 113, ensuring good contact between the first friction wheel 332 and the second friction wheel 333 and the sliding rod 113, reducing the sliding between the two, and improving the running stability.

[0045] For the guiding component 400 in this embodiment, as Figure 4 shown, the first guiding member 410 on one side of the printing platform 100 is set as a guiding convex block. The guiding convex block is connected to the printing platform 100. A guiding sliding groove 422 is provided on the bottom plate 200. Openings are provided at both ends of the guiding sliding groove 422. The guiding convex block is slidably and detachably clamped in the guiding sliding groove 422. When the printing platform 100 is disassembled, the guiding convex block is separated from the guiding sliding groove 422 through the openings at both ends. The first guiding member 410 on the other side of the printing platform 100 is set as a guiding pulley 412. The guiding pulley 412 can directly slide on the bottom plate 200. When the printing platform is disassembled, the guiding pulley 412 directly detaches from the bottom plate 200.

[0046] Embodiment 4

[0047] In some other embodiments, as Figure 6As shown in the figure, the Y-axis driving assembly 300 includes a fourth driving unit 341, a driving gear 342, and a driven wheel 343. The driving gear 342 is rotatably arranged on the bottom plate 200, the driven wheel 343 is arranged on the bottom plate 200 at intervals, the fourth driving unit 341 is arranged on the bottom plate 200, and the power output end of the fourth driving unit 341 is connected to the driving gear 342. The fourth driving unit 341 is used to drive the driving gear 342 to rotate. In this embodiment, the connecting member 110 is a rack 114. The rack 114 is installed on one side of the printing platform 100 close to the bottom plate 200 in the Y-axis direction through a third fastener. The rack 114 is detachably connected to the driving gear 342, and the rack 114 slidably abuts against the driven wheel 343.

[0048] Specifically, the driven wheels 343 are arranged in two rows along the Y-axis, and there is an interval between the two rows of driven wheels 343. The rack 114 is movably inserted into this interval. That is to say, the rack 114 can reciprocally move against the driven wheel 343 under the drive of the driving gear 342, so that the driven wheel 343 defines the moving direction of the rack 114. Specifically, the third fastener is a bolt or a screw. By detachably meshing the rack 114 with the driving gear 342, when the fourth driving unit 341 drives the driving gear 342 to rotate, the rack 114 can be driven to reciprocally move along the Y-axis. When the printing platform 100 needs to be disassembled and assembled, the rack 114 can be directly detached from the driving gear 342 and the driven wheel 343. When the rack 114 is disassembled, there is no need for additional operations to disconnect their connection. When the rack 114 is installed, it can also be directly connected to the driving gear 342 and the driven wheel 343, which has the advantages of simple operation and convenient use.

[0049] For the guiding assembly 400 in this embodiment, as Figure 6 shown, the first guiding members 410 on both sides of the printing platform 100 include a sliding member and a guiding pulley 412. The guiding pulley 412 is rotatably arranged on one side of the sliding member. The sliding member is connected to the printing platform 100. Guiding chutes 422 are provided on both sides of the bottom plate 200. Openings are provided at both ends of the guiding chutes 422. The guiding pulley 412 is slidably and detachably clamped in the guiding chutes 422. When the printing platform 100 is disassembled, the guiding pulley 412 is separated from the guiding chutes 422 through the openings at both ends.

[0050] In an exemplary embodiment, in order to make the movement stability of the printing platform 100 better, as Figures 1 to 3As shown, by setting the first guiding member 410 as a guiding shaft 411 and the second guiding member 420 as a guiding sleeve 421, the guiding shaft 411 is slidably and detachably arranged in the guiding sleeve 421. The guiding shaft 411 slides in the guiding sleeve 421. The guiding shaft 411 and the guiding sleeve 421 have high-precision dimensional tolerances and geometric tolerances, which can ensure the running stability of the printing platform 100 and improve the moving precision of the printing platform 100. Further, the guiding shaft 411 also has high strength and wear resistance in the guiding sleeve 421 and has a long service life. In another embodiment, the first guiding member 410 can also be a guiding pulley 412, and the second guiding member 420 can also be a guiding chute 422. The guiding pulley 412 is slidably and detachably arranged in the guiding chute 422. By setting the first guiding member 410 and the second guiding member 420 as the guiding pulley 412 and the guiding chute 422, the guiding pulley 412 can be conveniently installed in the guiding chute 422, and the heavy-load capacity between the two is stronger, having the advantage of convenient use.

[0051] In an alternative embodiment, as Figures 1 to 3 shown, the printing platform mechanism further includes a detection assembly 500. The detection assembly 500 includes a first photoelectric sensor 510, a first induction sheet 520, a second photoelectric sensor 530, and a second induction sheet 540.
