[0023] Embodiment 1
[0024] Please refer to Figure 1 , an embodiment of the present utility model provides a multi-station flow-through printing device, including: a printing platform 1 and an auxiliary printing device 41 disposed on the printing platform 1, an inkjet carriage 31, two parallelly arranged carriers 2 that can reciprocate in a first direction, and a first cross beam 3 and a second cross beam 4 located on the moving path of the carrier 2.
[0025] Specifically, the first carrier and the second carrier are arranged in parallel along the first direction on the printing platform 1, and each carrier can independently reciprocate in the first direction on the printing platform 1; the first cross beam 3 and the second cross beam 4 are arranged in parallel along the second direction on the moving path of each carrier, and the first direction and the second direction are perpendicular to each other; the inkjet carriage 31 is installed on the first cross beam 3 and can reciprocate in the second direction on the first cross beam 3, and the resulting reciprocating printing process is: the first carrier → the second carrier → the first carrier → the second carrier; the auxiliary printing device 41 is installed on the second cross beam 4 and can reciprocate in the second direction on the second cross beam 4, and the resulting reciprocating processing process is: the second carrier → the first carrier → the second carrier → the first carrier; by adjusting the reciprocating movement speed of the inkjet carriage 31 and the auxiliary printing device 41, it can be realized that when the inkjet carriage 31 performs inkjet printing on a certain carrier, the auxiliary printing device 41 performs auxiliary printing operations before or after the inkjet printing operation on another carrier. The first cross beam 3 and the second cross beam 4 are arranged in parallel along the second direction, ensuring that when the inkjet carriage 31 and the auxiliary printing device 41 move along the cross beam, they always maintain the relative position with the printing medium on each carrier, avoiding the need for attitude adjustment to align the printing medium after moving the position, and improving the printing speed. In other embodiments, a plurality of carriers 2 can be arranged in parallel along the first direction on the printing platform 1.
[0026] Furthermore, we define the intersection of the first carrier table and the second cross beam 4 as the first working station, the intersection of the first carrier table and the first cross beam 3 as the second working station, the intersection of the second carrier table and the second cross beam 4 as the third working station, and the intersection of the second carrier table and the first cross beam 3 as the fourth working station. During the reciprocating movement of the first carrier table along the first direction, it first drives the un-inked printing substrate to move to the first working station. At this time, the auxiliary printing device 41 moves along the second cross beam 4 to the first working station and completes the auxiliary printing operations before inkjet printing, such as cleaning the surface of the printing substrate. Subsequently, the printing substrate moves with the first carrier table to the second working station. At this time, the inkjet carriage 31 moves along the first cross beam 3 to the second working station and completes the inkjet printing operation. Finally, the first carrier table reciprocates and drives the printed substrate that has completed inkjet printing to move back to the first working station. At this time, the auxiliary printing device 41 moves along the second cross beam 4 to the first working station again and cures the surface of the printing substrate, completing the auxiliary printing operations after inkjet printing, such as final curing.
[0027] Synchronously, the second carrier table also makes a reciprocating movement along the first direction and drives the printing substrate to reciprocate between the third working station and the fourth working station; the inkjet carriage 31 can reciprocate between the second working station and the fourth working station on the first cross beam 3, and the auxiliary printing device 41 can reciprocate between the first working station and the third working station on the second cross beam 4. By coordinating the reciprocating movement speeds of each, multi-station cooperative operations can be achieved. The auxiliary printing operations before and after inkjet printing are gradually completed at the first working station or the third working station, and the inkjet printing operation is completed at the second working station or the fourth working station. In this way, all the auxiliary printing operation processes and inkjet printing operation processes can be completed on one device, and the equipment integration degree is high.
[0028] In one embodiment:
[0029] The auxiliary printing device 41 includes a cleaning mechanism 411 and a curing mechanism 412. The cleaning mechanism 411 and the curing mechanism 412 are respectively disposed opposite to both sides of the second cross beam 4. It can be understood that the cleaning mechanism 411 and the curing mechanism 412 are respectively arranged on both sides of the second cross beam 4, and the symmetric arrangement is more conducive to the balance of the auxiliary printing device 41 during reciprocating movement on the second cross beam 4, ensuring the stable force on the second cross beam 4. The cleaning mechanism 411 can be a blowing cleaning mechanism, a plasma cleaning mechanism, etc.; before the inkjet printing operation, the surface of the printing substrate is cleaned to prevent dust or other foreign objects from contaminating the printing surface of the printing substrate and affecting the printing quality. After the printing substrate undergoes the auxiliary printing operation before inkjet printing by the cleaning mechanism 411, it moves to the second or fourth station with the printing substrate carrier 21 to complete the inkjet printing operation. The printing substrate that has completed the inkjet printing operation then reciprocates back to the first or third station with the printing substrate carrier 21, and the surface of the printing substrate is cured by the curing mechanism 412 to complete the auxiliary printing operation after inkjet printing. The auxiliary printing device 41 first completes the auxiliary printing operation before inkjet printing by the cleaning mechanism 411 at the first or third station, and when the printing substrate returns to the first or third station after completing the inkjet operation process, the curing mechanism 412 then performs the final curing and other auxiliary printing operations after inkjet printing on the printing substrate, realizing the flexible use of the first or third station and improving the utilization rate of the station.
[0030] In one embodiment:
[0031] The curing mechanism 412 includes a curing lamp, a curing seal cover, and a blower sewage disposal device. The curing lamp is fixed inside the curing seal cover, and the upper end of the curing seal cover is fixedly connected to the blower sewage disposal device. In some printing tasks, the required inkjet volume far exceeds the conventional usage. When performing the final curing and other auxiliary printing operations, waste gas treatment also needs to be carried out simultaneously; because during the curing operation, due to the inkjet volume exceeding the conventional usage, a large amount of volatile organic compounds will be generated. The structures such as the curing seal cover and the blower sewage disposal device are provided to treat the waste gas and make it harmless. Such a structural improvement is more conducive to the physical health of the staff and environmental protection.
[0032] In one embodiment:
[0033] Please refer to Figure 2 , the carrier table 2 includes a first driving device disposed on the printing platform 1 and a printing substrate carrier 21 installed on the carrier table 2. The printing substrate carrier 21 can stably fix the printing substrate and, under the drive of the first driving device, reciprocate along the first direction, thereby driving the printing substrate to reciprocate along the first direction, enabling the printing substrate to reciprocate between different stations, without generating displacement due to inertia and affecting the printing quality, and flexibly using different stations to complete different processes.
[0034] In one embodiment:
[0035] The stage 2 further includes a first positioning mechanism and a second positioning mechanism. The first positioning mechanism is located at the intersection of the stage 2 and the second cross beam 4, and can accurately fix the printing substrate carrier 21 directly below the second cross beam 4. The second fixing mechanism is located at the intersection of the stage 2 and the first cross beam 3, and can accurately fix the printing substrate carrier 21 directly below the first cross beam 3. The first positioning mechanism and the second positioning mechanism can assist the moving printing substrate carrier 21 to decelerate and accurately stop at the corresponding positions, so that the auxiliary printing device 41 and the inkjet carriage 31 can accurately align with the printing substrate fixed on the printing substrate carrier 21, and the effects of the auxiliary printing operation and the inkjet printing operation are better.
[0036] In one embodiment:
[0037] A plurality of stages 2 are arranged in parallel on the printing platform 1. The first cross beam 3 is provided with an independent driving device, and this independent driving device drives the inkjet carriage 31 to reciprocate along the first cross beam 3. The second cross beam 4 is also provided with an independent driving device, and this independent driving device drives the auxiliary printing device 41 to reciprocate along the second cross beam 4. The independently provided driving devices can respectively adjust the reciprocating speeds of the inkjet carriage 31 and the auxiliary printing device 41, so that the inkjet carriage 31 and the auxiliary printing device 41 reciprocate between different stages according to the needs of the printing task. When a plurality of stages 2 are arranged in parallel on the printing platform 1, the inkjet carriage 31 and the auxiliary printing device 41 need to cross a certain stage to reach another stage to complete the required operation process. To achieve this purpose, the inkjet carriage 31 and the auxiliary printing device 41 need to dynamically adjust the reciprocating speed, and the provided independent driving devices can optimize this dynamic adjustment process.
[0038] In one embodiment:
[0039] Please refer to Figure 2 , the printing device further includes a maintenance station 32, and the maintenance station 32 is arranged at one end of the first cross beam 3. Since the inkjet carriage 31 can reciprocate on the first cross beam 3 to perform inkjet printing operations on the printing substrates on multiple stages, when regular maintenance and repair are required, the inkjet carriage 31 can move along the first cross beam 3 to the maintenance station 32 located at the end of the first cross beam 3 for maintenance operations.
[0040] A further measure is to provide a moisture retaining sponge and a blade on the maintenance station 32. After the inkjet carriage 31 reaches the maintenance station 32, the moisture retaining sponge and the blade are used to perform maintenance operations on the nozzle of the inkjet carriage 31. Further, for the convenience of operation, the blade is provided with a second driving device, and the second driving device is fixedly connected to the blade and can drive the blade to lift to a suitable position for convenient maintenance operations.
[0041] In one embodiment:
[0042] As Figure 2 shown, the printing device is further provided with a protective fence 5 for isolating the printing platform 1 that is performing a printing operation from external interference, ensuring the working state of the printing platform 1 and protecting the safety of the staff.
[0043] In the embodiment of the present utility model, by providing a plurality of carriers 2 that can reciprocate in a first direction, a first cross beam 3 and a second cross beam 4 located on the movement paths of the respective carriers 2, an inkjet carriage 31 and an auxiliary printing device 41 that can move in a second direction perpendicular to the first direction on each cross beam, a plurality of workstations are formed at the intersections of the carriers 2 and the respective cross beams. The substrate can reciprocate between different workstations with the carrier 2, flexibly use different workstations, and complete all processes such as auxiliary printing operations before inkjet printing, inkjet printing operations, and auxiliary printing operations after inkjet printing, realizing multi-station flow printing, with high equipment integration, improved production efficiency, and reduced production costs.
[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
