Description

Technical Field

[0001] This application relates to the technical field of inkjet printing, and particularly relates to a split nozzle module and an inkjet printing system. Background Art

[0002] Inkjet printing technology has broad application prospects in multiple manufacturing fields such as information, energy, medical, and national defense. With the rapid development of technology, it has also been increasingly applied in emerging fields such as flexible devices such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, and smart skins.

[0003] The core component of an inkjet printing device is the nozzle module. Generally, the nozzle module includes a nozzle assembly and an ink supply assembly. The nozzle assembly and the ink supply assembly are integrated and can move synchronously in the directions perpendicular to the printing direction and the vertical direction. As the substrate moves in the printing direction, the nozzle module prints on the substrate.

[0004] In related technologies, the nozzle module includes a primary ink cartridge, a secondary ink cartridge, a control box, and a nozzle assembly. The primary ink cartridge supplies ink to the secondary ink cartridge to maintain the stability of the functional liquid in the secondary ink cartridge. The secondary ink cartridge supplies ink to the nozzle assembly to provide the functional liquid required for printing by the nozzle assembly. The control box controls the ink supply flow rate and voltage.

[0005] However, as the size of the substrate to be printed increases, the nozzles in the nozzle module are generally spliced by multiple nozzles. Correspondingly, the structures of the primary ink cartridge, the secondary ink cartridge, and the control box that need to be arranged in the ink supply assembly will become more complex. Therefore, the weight of the nozzle module is relatively large.

[0006] The problems brought by the weight and size of the nozzle module are as follows: On the one hand, during printing, the nozzle module needs to move up and down to a specified printing height. Due to the relatively large weight of the nozzle module, the load on the driving member that drives the nozzle module to move up and down is relatively large, which easily causes the driving member to run unstably and it is difficult to ensure the running accuracy. Therefore, it is difficult to ensure the printing height, which affects the printing accuracy. On the second hand, when it is necessary to drive the nozzle module to slide on the frame in the direction perpendicular to the printing direction to adjust the printing position on the substrate, the friction between the nozzle module and the frame is relatively large. Therefore, it is also difficult to ensure the accuracy of the lateral movement of the nozzle module, which also has an adverse effect on the printing accuracy. On the third hand, the ink supply assembly in the nozzle module is stacked on the nozzle assembly. The bottom plate of the nozzle assembly not only provides splicing and installation for multiple nozzles, but also needs to bear other components of the nozzle assembly above it and the ink supply assembly. Therefore, the load on the bottom plate is relatively large, and the bottom plate is prone to deformation, resulting in inconsistent heights of multiple nozzles. Therefore, it is difficult to ensure the printing accuracy. Summary of the Invention

[0007] The embodiment of the present application provides a split nozzle module and an inkjet printing system to solve the technical problems in the related art that the accuracy of the lifting and lateral movement of the nozzle module is difficult to ensure, and the height consistency of multiple nozzles after splicing is poor, making it difficult to ensure printing accuracy.

Detailed implementation manners

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0045] The embodiment of the present application provides a split nozzle module and an inkjet printing system. By setting the primary component, secondary component, and nozzle component separately, the load on the bottom plate of the mounting seat in the nozzle component is reduced, the load on the nozzle lifting driving part is reduced, the height consistency of multiple nozzle modules is improved, and the lifting movement accuracy of the nozzle module is higher, thereby improving the printing accuracy. The present application solves the technical problems in the related art that it is difficult to ensure the accuracy of the lifting movement and cross - translation movement of the nozzle module, and the height consistency is poor after multiple nozzles are spliced, making it difficult to ensure the printing accuracy.

[0046] Reference Figure 1 A split type nozzle module comprises a gantry 1, a transverse moving assembly 2, a primary assembly 3, a secondary assembly 4 and a nozzle assembly 5. The transverse moving assembly 2 is arranged on the gantry 1, and drives the primary assembly 3, the secondary assembly 4 and the nozzle assembly 5 to move along the length direction of the crossbeam 11. The primary assembly 3 supplies ink to the secondary assembly 4, the secondary assembly 4 supplies ink to the nozzle assembly 5, and the nozzle assembly 5 is used for printing.

[0047] Reference Figure 1 and Figure 2 Specifically, the transverse moving assembly 2 includes a bearing block 21 and a transverse moving driving member 22. The bearing block 21 is in a square frame shape and is sleeved on the cross beam 11 of the gantry 1. The bearing block 21 can slide along the length direction of the cross beam 11. The primary assembly 3, the secondary assembly 4 and the nozzle assembly 5 are all installed on the bearing block 21. The transverse moving driving member 22 is connected to the bearing block 21 to drive the bearing block 21 and the primary assembly 3, the secondary assembly 4 and the nozzle assembly 5 on the bearing block 21 to move transversely in the length direction of the cross beam 11.

[0048] Furthermore, the traverse assembly 2 further includes an air flotation assembly, and a plurality of air holes 21b are provided on the inner side of the bearing block 21. The air flotation assembly is in communication with the plurality of air holes 21b to ventilate the air holes 21b, so that an air film is formed between the bearing block 21 and the cross beam 11. The bearing block 21 is supported by the cross beam 11 in the form of air flotation.

[0049] In this arrangement, due to the presence of an air film between the bearing block 21 and the cross beam 11, when the bearing block 21 moves horizontally relative to the cross beam 11, there is basically no friction between the bearing block 21 and the cross beam 11. Therefore, when the cross-movement driving member 22 drives the bearing block 21 to move horizontally, the cross-movement precision of the bearing block 21 is higher, so the cross-movement precision of the nozzle assembly 5 is better, which facilitates the movement of the nozzle assembly 5 to a specified position, thereby improving the printing precision. In addition, since the bearing block 21 is sleeved on the cross beam 11, the bearing block 21 is not easily deflected due to the force on the edge, which ensures the precision of the movement direction of the bearing block 21, further ensures the precision of the cross-movement direction of the nozzle assembly 5, and improves the printing precision.

[0050] In this embodiment, the air flotation component includes an external air supply component.

[0051] Reference Figures 1-3 , wherein a vertical side surface of the bearing block 21 is the mounting surface 21a. The primary component 3 is mounted on the top surface of the bearing block 21 or the side away from the mounting surface 21a. In this embodiment, the primary component 3 is mounted on the top surface of the bearing block 21, and the secondary component 4 and the nozzle component 5 are independently mounted on the mounting surface 21a of the bearing block 21. In some embodiments, the primary component 3 and the secondary component 4 are respectively mounted on two opposite sides of the bearing block 21 to balance the force on the bearing block 21.

[0052] With such a setting, since the first-level component 3 is installed on the top surface of the bearing block 21, the load on the side of the bearing block 21 is reduced, and the overall center of gravity of the first-level component 3, the second-level component 4, and the nozzle component 5 is closer to the center of gravity of the bearing block 21. The bearing block 21 is not prone to skew, thereby improving the accuracy of the transverse movement of the bearing block 21 and the nozzle component 5, and achieving higher printing accuracy.

[0053] In addition, since the first-level component 3, the second-level component 4, and the nozzle component 5 are separately designed and independently installed on the bearing block 21, the nozzle component 5 does not support the first-level component 3 and the second-level component 4. The force on the nozzle component 5 is reduced, ensuring that the nozzle component 5 maintains its shape and is not easily deformed by the force, thus guaranteeing the printing accuracy.

[0054] It should be noted that during inkjet printing, the accuracy of the printing landing point is at the micron level. Slight deformation of the nozzle component 5 can easily have an adverse impact on the position of the printing landing point.

[0055] Refer to Figure 1 and Figure 2 , specifically, the first-level component 3 includes a first-level ink cartridge 31, and the first-level ink cartridge 31 is communicated with an external ink supply source to replenish ink to the first-level ink cartridge 31 through the external ink supply source. The second-level component 4 includes a second-level ink cartridge 41, and the second-level ink cartridge 41 is connected to the first-level ink cartridge 31 through a pipeline. The pipeline between the first-level ink cartridge 31 and the second-level ink cartridge 41 is a flexible hose. The first-level ink cartridge 31 supplies ink to the second-level ink cartridge 41 and maintains the functional liquid in the second-level ink cartridge 41 within a constant range. The second-level ink cartridge 41 is connected to the nozzle component 5 through a pipeline to supply ink to the nozzle component 5.

[0056] With such a setting, the first-level ink cartridge 31 first sends the functional liquid to the second-level ink cartridge 41, and then the second-level ink cartridge 41 supplies the functional liquid to the nozzle component 5. By maintaining the functional liquid in the second-level ink cartridge 41 within a constant range through the first-level ink cartridge 31, it is possible to ensure a stable supply of the functional liquid to the nozzle component 5 and guarantee the normal progress of the printing process.

[0057] Among them, since the first-level ink cartridge 31 and the second-level ink cartridge 41 are separately arranged, it is convenient to separately repair and maintain the first-level ink cartridge 31 and the second-level ink cartridge 41.

[0058] Refer to Figures 4-6 , specifically, the first-level ink cartridge 31 includes a plurality of first-level ink storage cartridges 311 and a plurality of locking components 312. The plurality of first-level ink storage cartridges 311 are arranged side by side along the length direction perpendicular to the cross beam 11. The first-level ink storage cartridges 311 are slidably arranged on the bearing block 21 through a guide rail group, and the sliding direction of the first-level ink storage cartridges 311 is consistent with the length direction of the cross beam 11. Among them, due to the setting of the guide rail group, there is a gap between the bottom surface of the first-level ink storage cartridges 311 and the top surface of the bearing block 21.

[0059] Refer toFigures 4-6 A plurality of locking components 312 respectively correspond to a plurality of first-level ink cartridges 311, and the locking components 312 restrict the first-level ink cartridges 311 from sliding relative to the bearing block 21.

[0060] With this arrangement, by releasing the sliding restriction of the locking component 312 on the first-level ink cartridge 311 and driving the first-level ink cartridge 311 to move along the length direction of the cross beam 11, the installation and removal of the first-level ink cartridge 311 can be facilitated. Among them, since the sliding direction of the first-level ink cartridge 311 is consistent with the length direction of the cross beam 11, and the bearing block 21 also slides along the length direction of the cross beam 11, a sliding space for the first-level ink cartridge 311 is left in the length direction of the cross beam 11. The sliding direction of the first-level ink cartridge 311 is set more reasonably and is not easily interfered by other structures.

[0061] Refer to Figures 4-6 Among them, the locking component 312 includes a lock catch 3122, a locking bolt 3123, and a plurality of suction attachments 3121. The lock catch 3122 and the suction attachments 3121 are arranged at intervals in the length direction of the cross beam 11 and are respectively used to abut against the opposite side surfaces of the first-level ink cartridge 311.

[0062] Specifically, a plurality of suction attachments 3121 are all fixed on the top surface of the bearing block 21 and are used to abut against the side surface of the first-level ink cartridge 311. In this embodiment, the suction attachment 3121 includes a magnet, and the outer shell of the first-level ink cartridge 311 is made of steel. After the first-level ink cartridge 311 abuts against the magnet, it is adsorbed by the magnet to perform preliminary positioning on the first-level ink cartridge 311. In other embodiments, the suction attachment 3121 may also include a suction cup.

[0063] Refer to Figures 4-6 A limiting block 311a is fixed at the bottom of the first-level ink cartridge 311, and the locking end of the lock catch 3122 abuts against the limiting block 311a to tightly hold the first-level ink cartridge 311. The first-level ink cartridge 311 is clamped and fixed by the lock catch 3122 and the suction attachment 3121.

[0064] Refer to Figures 4-6 Specifically, the lock catch 3122 is slidably arranged on the bearing block 21 along a direction perpendicular to the length direction of the cross beam 11, and the lock catch 3122 is slid to be staggered with the limiting block 311a in the direction perpendicular to the length direction of the cross beam 11.

[0065] With this arrangement, by sliding the lock catch 3122 to be misaligned with the limiting block 311a, the lock catch 3122 can avoid the sliding path of the limiting block 311a, facilitating the removal of the first-level ink cartridge 311 from the bearing block 21 and facilitating the installation of the first-level ink cartridge 311 onto the bearing block 21.

[0066] Refer to Figures 4-6, the locking bolt 3123 is threadedly connected to the bearing block 21, and the locking bolt 3123 is adapted to abut against the locking buckle 3122 to limit the sliding of the locking buckle 3122. Specifically, a sliding groove is provided on the side surface of the bearing block 21, a part of the locking buckle 3122 is inserted into the sliding groove, and one end of the locking bolt 3123 extends into the sliding groove to abut against the locking buckle 3122.

[0067] With such a setting, the sliding of the locking buckle 3122 is restricted by the locking bolt 3123, so as to ensure that the locking buckle 3122 stably abuts against the limiting block 311a, and the primary ink cartridge 311 is stably fixed on the bearing block 21.

[0068] Refer to Figure 2 , further, the primary assembly 3 further includes a control box 32, and the control box 32 is installed on the top surface of the bearing block 21. The orthographic projection of the center of gravity of the primary assembly 3 on the top surface of the bearing block 21 is set to be biased towards the edge away from the mounting surface 21a.

[0069] With such a setting, by designing the installation positions of the various parts of the primary assembly 3 relative to the bearing block 21, the center of gravity position of the primary assembly 3 is adjusted. The overall center of gravity of the primary assembly 3, the secondary assembly 4, and the nozzle assembly 5 is closer to the center of gravity of the bearing block 21, and the bearing block 21 is not prone to skew. Therefore, when the nozzle assembly 5 on the bearing block 21 moves horizontally, the accuracy is higher.

[0070] Refer to Figure 2 and Figure 7 , further, the traversing assembly 2 further includes a counterweight 23, and the counterweight 23 is fixed to the bearing block 21 by bolts, and the counterweight 23 and the secondary assembly 4 are respectively located on the opposite side surfaces of the bearing block 21.

[0071] Due to the setting of the counterweight 23, the force on the bearing block 21 is more uniform, and the bearing block 21 is not prone to skew. Therefore, when the nozzle assembly 5 on the bearing block 21 moves horizontally, the accuracy is higher.

[0072] Refer to Figure 1 and Figure 7 , further, the traversing assembly 2 further includes a drag chain 24, the fixed end of the drag chain 24 is installed on the cross beam 11, and the free end of the drag chain 24 is connected to the side surface of the bearing block 21 facing away from the secondary assembly 4.

[0073] Refer to Figure 1 and Figure 7 , specifically, the drag chain 24 includes a main connecting plate 241, a movable connecting plate 242 and a drag chain body (not shown in the figure), the main connecting plate 241 is fixed to the cross beam 11 by bolts, the movable connecting plate 242 is fixed to one side surface of the bearing block 21 facing away from its mounting surface 21a by bolts, the fixed end of the drag chain body is installed on the main connecting plate 241, and the movable end of the drag chain body is installed on the movable connecting plate 242.

[0074] With such an arrangement, part of the weight of the drag chain 24 is borne by the bearing block 21, and the force application position of the drag chain 24 on the bearing block 21 is far from the mounting surface 21a, so as to balance the bearing block 21 through the weight of the drag chain 24, and the bearing block 21 is not prone to skew due to excessive force at its mounting surface 21a.

[0075] In addition, through the installation positions of the drag chain 24 and the primary assembly 3, the force exerted on the bearing block 21 from the secondary assembly 4 and the nozzle assembly 5 is balanced and compensated. The weight of the additionally provided counterweight 23 can be reduced, thereby reducing the overall load of the bearing block 21.

[0076] Refer to Figure 1 , wherein, the transverse movement driving member 22 includes a stator part and a rotor part. A receiving groove is formed in the side surface of the cross beam 11 along its length direction, the stator part is installed in the receiving groove, the rotor part is fixed on the bearing block 21, and the rotor part and the stator part cooperate to form a linear motor.

[0077] With such an arrangement, the linear motor is integrated into the cross beam 11 and the bearing block 21, and the integration degree of the cross beam 11, the bearing block 21 and the transverse movement driving member 22 is higher, which is convenient for leaving space for the installation of the drag chain 24, the counterweight 23, the primary assembly 3, the secondary assembly 4 and the nozzle assembly 5, and the installation positions of the drag chain 24, the counterweight 23, the primary assembly 3, the secondary assembly 4 and the nozzle assembly 5 have higher flexibility.

[0078] Refer to Figure 1 , Figure 2 and Figure 8 , wherein, the secondary assembly 4 includes a secondary ink cartridge 41, the secondary ink cartridge 41 is communicated with the primary ink cartridge 31 through a pipeline, and a plurality of secondary ink cartridges 41 are installed on the mounting surface 21a.

[0079] Refer to Figure 1 , Figure 3 and Figure 9 , the nozzle assembly 5 includes a plurality of nozzle modules 51, and the secondary ink cartridge 41 includes a plurality of secondary ink storage cartridges. A plurality of secondary ink storage cartridges are respectively connected with a plurality of primary ink storage cartridges 311 through pipelines, and a plurality of nozzle assemblies 5 are respectively connected with a plurality of secondary ink storage cartridges through pipelines.

[0080] With such an arrangement, each nozzle assembly 5 corresponds to a primary ink storage cartridge 311 and a secondary ink storage cartridge, and a plurality of nozzle assemblies 5 supply ink independently to ensure more stable ink supply. In addition, it is convenient to judge whether the ink supply of the nozzle module 51 is normal according to the printing situation, and it is convenient to quickly locate the primary ink storage cartridge 311 and the secondary ink storage cartridge.

[0081] Refer to Figure 1 , Figure 3 and Figure 9, wherein, the nozzle assembly 5 further includes a nozzle lifting drive member 53 and a mounting base 52. The mounting base 52 is located below the secondary assembly 4. The mounting base 52 is arranged to be lifted and slid along a guide rail group on the mounting surface 21a. The nozzle lifting drive member 53 is mounted on the mounting surface 21a. The nozzle lifting drive member 53 is drivingly connected to the mounting base 52 to drive the mounting base 52 to lift and lower. A plurality of nozzle modules 51 are all mounted on the bottom plate of the mounting base 52.

[0082] With such an arrangement, the primary assembly 3, the secondary assembly 4 and the nozzle assembly 5 are separately arranged, which reduces the load on the bottom plate of the mounting base 52 in the nozzle assembly 5. The bottom plate is not easily deformed, and the mounting heights of the plurality of nozzle modules 51 after being spliced and mounted on the bottom plate are more consistent, thus ensuring the printing accuracy. In addition, the secondary assembly 4 is independently mounted on the bearing block 21 separately from the nozzle assembly 5. When the nozzle lifting drive member 53 in the nozzle assembly 5 drives the nozzle module 51 to lift and lower, the load on the nozzle lifting drive member 53 is greatly reduced, and it is easier to ensure the accuracy of the lifting movement of the nozzle module 51, so that the nozzle module 51 can be accurately adjusted to the printing height required by the process, improving the printing accuracy.

[0083] In this embodiment, the nozzle lifting drive member 53 includes a linear motor or a lead screw mechanism.

[0084] Referring to Figure 1 、 Figure 2 and Figure 8 , further, the secondary assembly 4 further includes a secondary lifting drive member 42. The secondary ink cartridge 41 is arranged to be lifted and slid along a guide rail group on the mounting surface 21a. The secondary lifting drive member 42 is mounted on the mounting surface 21a. The secondary lifting drive member 42 is drivingly connected to the secondary ink cartridge 41 to drive the secondary ink cartridge 41 to lift and lower. Wherein, the secondary ink cartridge 41 and the mounting base 52 are lifted and lowered synchronously.

[0085] With such an arrangement, as the nozzle module 51 lifts and lowers, the secondary ink cartridge 41 lifts and lowers synchronously to maintain the distance between the secondary ink cartridge 41 and the nozzle module 51. It is convenient to design the pipeline connecting the secondary ink cartridge 41 and the nozzle module 51 to be shorter, shortening the flow distance of the functional liquid in the pipeline, thus ensuring the quality of the functional liquid supplied to the nozzle module 51.

[0086] In addition, the secondary ink cartridge 41 and the nozzle module 51 move independently in lifting and lowering. The loads on both the secondary lifting drive member 42 and the nozzle lifting drive member 53 are small. Therefore, the lifting and lowering movement accuracy of the secondary ink cartridge 41 and the nozzle module 51 is higher, facilitating the precise movement of the nozzle module 51 to the specified printing height and improving the printing quality.

[0087] The embodiment of the present application provides a split nozzle module, in which the primary component 3, the secondary component 4, and the nozzle component 5 are separately arranged, reducing the load on the bottom plate of the mounting base 52 in the nozzle component 5. The bottom plate is not easily deformed, and the mounting heights of multiple nozzle modules 51 after being spliced and mounted on the bottom plate are more consistent, thus ensuring the printing accuracy. Since the carrier block 21 in the transverse movement component 2 is sleeved on the cross beam 11, the carrier block 21 is not easily skewed due to edge force, ensuring the accuracy of the movement direction of the carrier block 21, and thus ensuring the movement direction accuracy of the nozzle component 5 and improving the printing accuracy.

[0088] In addition, since the primary component 3 is installed on the top surface of the carrier block 21, the load on the side surface of the carrier block 21 is reduced, and the overall center of gravity of the primary component 3, the secondary component 4, and the nozzle component 5 is closer to the center of gravity of the carrier block 21. The carrier block 21 is not easily skewed, thereby improving the accuracy of the transverse movement of the carrier block 21 and the nozzle component 5, and the printing accuracy is higher.

[0089] Furthermore, the secondary component 4 is independently installed on the carrier block 21 separately from the nozzle component 5. When the nozzle lifting drive 53 in the nozzle component 5 drives the nozzle module 51 to lift, the load on the nozzle lifting drive 53 is greatly reduced, making it easier to ensure the accuracy of the lifting movement of the nozzle module 51, so that the nozzle module 51 can be accurately adjusted to the printing height required by the process, improving the printing accuracy.
