Description

Technical Field

[0001] The present application relates to the technical field of display panel processing, and in particular to a printing module and printing equipment for large-size substrates. Background Art

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

[0003] The core component of the inkjet printing equipment is the nozzle. The nozzle moves along the length of the arrangement of the nozzle holes on the nozzle to print. The spacing of the nozzle holes in the printing direction determines the printing resolution, and the arrangement length of the nozzle holes in the printing direction determines the length of each printing process of the nozzle.

[0004] As substrates grow in size, a single printhead requires multiple lateral movements and reciprocating motions to print on medium- and large-sized substrates. As the required print resolution increases, the nozzle arrangement on a single printhead becomes difficult to meet the required resolution. Consequently, when a single printhead processes medium- and large-sized substrates with high-resolution printing requirements, not only is printing efficiency slow, but the print resolution also struggles to meet the required requirements.

[0005] In the related art, multiple nozzles are spliced together, and by arranging multiple nozzles in the printing direction, the projections of the nozzles of the multiple nozzles in the printing direction are interpolated to increase the printing density, thereby meeting the high-resolution printing requirements. At the same time, multiple nozzles are arranged in the length direction of the nozzles to lengthen the length of each printing process to improve printing efficiency.

[0006] If you need to splice print heads while ensuring the printing quality, you need to make multiple print heads seamlessly spliced. Figure 1 The nozzle holes of the multiple nozzles 24 arranged in the printing direction must be projected in the printing direction to form interpolation; at the same time, the arrangement length direction of the nozzle holes of the multiple nozzles 24 arranged in the nozzle hole arrangement length direction of the nozzles 24 is consistent, and the spacing between the nozzle holes of adjacent nozzles 24 at the splicing point in the printing direction is consistent with the spacing between the nozzle holes of a single nozzle 24 in the printing direction.

[0007] When splicing the nozzles, the nozzles are directly fixed to the nozzle holders by bolts, and it is necessary to ensure that the installation position of each nozzle meets the installation requirements to ensure that after multiple nozzles are assembled, multiple nozzle holes are interpolated and the length of the nozzle hole arrangement is increased.

[0008] The projected spacing of the nozzle holes on the print head in the printing direction is small, which can reach the micron level. Whether the nozzle holes of the nozzle head are interpolated or the nozzle hole arrangement length of the nozzle head is lengthened, the installation accuracy of the nozzle head is required to be high.

[0009] However, multiple nozzles are fixed to the nozzle holder by bolts, and the installation position accuracy of the nozzles is poor. It is also difficult to fine-tune the installation position of the nozzles, making it impossible to achieve seamless splicing of multiple nozzles. In addition, even if the installation position of the nozzles is adjusted by changing the connection position of the bolts and the nozzle holder, when assembling multiple nozzles, the positions of all the nozzles need to be adjusted in turn, and the adjustment efficiency is extremely low. Therefore, in the related art, the efficiency of splicing multiple nozzles is extremely low, and the installation accuracy of the nozzles is poor, making it difficult to achieve seamless splicing and unable to guarantee printing quality.

[0067] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0068] The present application provides a large-scale substrate printing module and printing equipment. The large-scale substrate printing module first uses multiple adjustment components to seamlessly splice the nozzles into a nozzle module, and then uses multiple correction components to correct the multiple nozzle modules separately to achieve the assembly of the printing module. The nozzle assembly efficiency is high and the nozzle installation accuracy is high, ensuring printing accuracy. This application solves the technical problems in the related art of extremely low efficiency and poor installation accuracy of multiple nozzles, making it difficult to achieve seamless splicing and unable to ensure printing quality.

[0069] Reference Figure 2 and Figure 3 , a printing module for large-size substrates, comprising a base 1, a plurality of nozzle modules 2, a plurality of correction components 3 and a plurality of fixing components 4. Each nozzle module 2 is mounted on the base 1 by a plurality of fixing components 4, and a plurality of nozzle modules 2 are arranged side by side in a first direction. The length direction of the arrangement of the nozzle holes in the nozzle module 2 is set along the second direction. The correction component 3 is mounted on the base 1, and the plurality of correction components 3 respectively adjust the positions of the plurality of nozzle modules 2 so that the length directions of the arrangement of the nozzle holes of the plurality of nozzle modules 2 are consistent. In this embodiment, the first direction and the second direction are arranged vertically. For ease of understanding, the X-axis direction in the figure is the first direction, and the Y-axis direction is the second direction.

[0070] The printing module is composed of a plurality of nozzle modules 2, each of which is composed of a plurality of nozzles 24. The plurality of nozzles 24 in the nozzle module 2 can be seamlessly spliced together first, so that the nozzle holes of the plurality of nozzles 24 in the nozzle module 2 are interpolated, and then the plurality of nozzle modules 2 are seamlessly spliced together. Therefore, when the plurality of nozzles 24 are assembled into a printing module, it is only necessary to further splice the plurality of seamlessly spliced nozzle modules 2 and adjust the installation positions of the plurality of nozzle modules 2. This can simultaneously adjust the installation positions of the plurality of nozzles 24, thereby improving the assembly efficiency of the printing module.

[0071] Reference Figure 3 and Figure 4 Specifically, the nozzle module 2 includes a mounting plate 21, multiple nozzles 24, and multiple adjustment assemblies 23. The mounting plate 21 is located in the mounting slot 11a and is rotatably connected to the base plate 11. The mounting plate 21 has multiple through-holes for the nozzles 24 to pass through. The bottom ends of the nozzles 24 pass through the through-holes to avoid interfering with the operation of the nozzle holes at the bottom of the nozzles 24.

[0072] Reference Figure 4-Figure 6 The nozzle holes of the nozzle head 24 are arranged along the second direction in their longitudinal direction. The nozzle head 24 slides along the second direction in the through-hole of the mounting plate 21. Multiple adjustment assemblies 23 correspond to the nozzle heads 24, and the adjustment assemblies 23 drive the nozzle heads 24 to slide and fix them. The projections of the nozzle holes of the multiple nozzle heads 24 of the nozzle module 2 in the printing direction form an interpolation.

[0073] Reference Figure 4-Figure 6 In this embodiment, the nozzle module 2 further includes a plurality of mounting seats 22, and a plurality of nozzles 24 are respectively fixed on the mounting seats 22, and the nozzles 24 are mounted on the mounting plate 21 through the mounting seats 22. The adjustment components 23 act on the mounting seats 22 to adjust the position of the nozzles 24.

[0074] Specifically, the positions of the plurality of mounting seats 22 and the plurality of nozzles 24 relative to the mounting plate 21 are adjusted by the plurality of adjusting components 23 , so as to achieve interpolation of the plurality of nozzle holes of the plurality of nozzles 24 .

[0075] Reference Figure 6 The mounting base 22 includes a horizontal portion and a vertical portion, and is generally L-shaped. The nozzle 24 is fixed to the vertical portion of the mounting base 22 , and the horizontal portion of the mounting base 22 is connected to the mounting plate 21 .

[0076] Reference Figure 4-Figure 6 Specifically, the mounting seat 22 is slidably disposed on the mounting plate 21 , the sliding direction of the mounting seat 22 is disposed along the second direction, and the length direction of the arrangement of the plurality of nozzle holes of the nozzle head 24 on the mounting seat 222 is disposed along the second direction.

[0077] With this arrangement, the position of the nozzle 24 relative to the mounting plate 21 can be changed by sliding the mounting base 22, so as to facilitate interpolation of the nozzle holes of the plurality of nozzles 24, so that the plurality of nozzles 24 are precisely spliced, thereby improving the printing resolution of the nozzle module 2.

[0078] In other embodiments, the spacing between the nozzle holes of the multiple nozzles 24 in the nozzle module 2 is consistent with the spacing between the nozzle holes on the nozzle heads 24, so that the spacing of the multiple nozzle holes of the multiple nozzle heads 24 after splicing in the second direction is consistent, so that the multiple nozzle heads 24 are precisely spliced, and the nozzle hole arrangement length of the nozzle module 2 after the multiple nozzle heads 24 are spliced is longer, which is suitable for the printing processing of large-size substrates and improves the processing efficiency.

[0079] Reference Figure 6-Figure 8 The adjustment assembly 23 includes a first adjustment structure 231. The first adjustment structure 231 includes a first fixed seat 2311, a first ejection member 2312, and an adjustment seat 2313. A portion of the first fixed seat 2311 is fixed to the mounting plate 21, and a portion of the first fixed seat 2311 is detachably connected to the mounting seat 22. The adjustment seat 2313 is fixed to the mounting seat 22, and the first ejection member 2312 is mounted on the first fixed seat 2311. The ejection tip of the first ejection member 2312 is adapted to move in the second direction and to push against the adjustment seat 2313.

[0080] Reference Figure 6-Figure 8Specifically, a portion of the first fixing seat 2311 is fixed to the mounting plate 21 by bolts. When the nozzle 24 is moved in the lengthwise direction of the arrangement of its nozzle holes to adjust the position of the nozzle 24, the first fixing seat 2311 is first released from the fixed state with the mounting seat 22. The pushing end of the first pushing member 2312 pushes the adjustment seat 2313 to move in the second direction, thereby synchronously driving the mounting seat 22 and the nozzle 24 to move in the second direction, thereby achieving the position adjustment of the nozzle 24. After the position adjustment of the nozzle 24 is completed, the first fixing seat 2311 is fixed to the mounting seat 22. At this time, the mounting seat 22, the first fixing seat 2311 and the mounting plate 21 are fixed together, and the movement of the mounting seat 22 relative to the mounting plate 21 is restricted, thereby fixing the position of the nozzle 24 relative to the mounting plate 21.

[0081] With this arrangement, the first push member 2312 is used to push the adjustment seat 2313 to change the movement form of the nozzle 24, and the movement accuracy is more controllable. Compared with directly sliding the nozzle 24 by hand, the accuracy is higher and the movement distance is more controllable, thereby improving the accuracy of adjusting the position of the nozzle 24 and improving the adjustment efficiency of the splicing position of the nozzle 24.

[0082] In this embodiment, the first ejecting member 2312 includes a micrometer head.

[0083] Reference Figure 6-Figure 8 The first adjustment structure 231 also includes a first connecting structure 2314, through which the first fixing seat 2311 and the mounting seat 22 are detachably connected. The first connecting structure 2314 includes a first threaded hole 23141, a first mounting hole 23142, and a first connecting bolt 23143. The first threaded hole 23141 is provided on the top surface of the mounting seat 22, and the first mounting hole 23142 is provided in the first fixing seat 2311 and extends through the first mounting hole 23142. The first connecting bolt 23143 passes through the first mounting hole 23142 and is threadedly engaged with the first threaded hole 23141. The head of the first connecting bolt 23143 is tightly abutted against the first fixing seat 2311. The diameter of the threaded section of the first connecting bolt 23143 is smaller than the diameter of the first mounting hole 23142.

[0084] With this arrangement, by tightening the first connecting bolt 23143, the head of the first connecting bolt 23143 is pressed against the first fixing seat 2311, thereby fixing the mounting seat 22 to the first fixing seat 2311. When the first ejector 2312 is needed to adjust the position of the nozzle 24, the first connecting bolt 23143 is loosened. Since the diameter of the threaded section of the first connecting bolt 23143 is smaller than the diameter of the first mounting hole 23142, the first connecting bolt 23143 can move relative to the first fixing seat 2311, thereby allowing the mounting seat 22 to move relative to the first fixing seat 2311. At this time, the first ejector 2312 can drive the adjustment seat 2313 and the mounting seat 22 to move relative to the first fixing seat 2311 and the mounting plate 21, thereby adjusting the position of the nozzle 24.

[0085] When the first ejection member 2312 is used to adjust the position of the nozzle 24, the first connecting bolt 23143 can be pre-tightened, that is, the head of the first connecting bolt 23143 abuts against the first fixing seat 2311. At this time, friction is generated between the head of the first connecting bolt 23143 and the first fixing seat 2311. This increases the damping of the movement of the mounting seat 22 relative to the first fixing seat 2311. At this time, when the first ejection member 2312 pushes the adjustment seat 2313 and the mounting seat 22 to move, the adjustment seat 2313 and the mounting seat 22 are less affected by inertia, and the movement distance of the adjustment seat 2313 and the mounting seat 22 is more controllable, thereby improving the accuracy of adjusting the position of the nozzle 24.

[0086] It should be noted that the spacing between the multiple nozzles of the nozzle head 24 is small, at the micron level, so the gap between the first connecting bolt 23143 and the hole wall of the first mounting hole 23142 is sufficient to meet the position fine-tuning requirements of the mounting base 22.

[0087] Reference Figure 6-Figure 8 Furthermore, the first adjustment structure 231 further includes an elastic member 2315, and both ends of the elastic member 2315 are respectively connected to the first fixing seat 2311 and the adjustment seat 2313. When the adjustment seat 2313 moves away from the first fixing seat 2311, the elastic member 2315 is further stretched.

[0088] The position of the elastic member 2315 ensures that the pushing top end of the first pushing member 2312 remains in a tight state with the adjusting seat 2313. Therefore, when the first pushing member 2312 pushes the adjusting seat 2313 to move, the movement distance of the pushing top end of the first pushing member 2312 is ensured to be consistent with the movement distance of the adjusting seat 2313, so as to facilitate the precise movement of the adjusting seat 2313 by the specified distance, thereby improving the accuracy of the position adjustment of the nozzle 24.

[0089] In addition, when the adjusting seat 2313 is fixed away from the first fixed seat 2311, the elastic member 2315 is deformed to generate an elastic force between the adjusting seat 2313 and the first fixed seat 2311. The elastic force increases the damping of the movement of the mounting seat 22 relative to the first fixed seat 2311. At this time, when the first pushing member 2312 pushes the adjusting seat 2313 and the mounting seat 22 to move, the adjusting seat 2313 and the mounting seat 22 are less affected by inertia, and the movement distance of the adjusting seat 2313 and the mounting seat 22 is more controllable, thereby improving the accuracy of the position adjustment of the nozzle 24.

[0090] In this embodiment, the elastic member 2315 includes a spring. In other embodiments, the elastic member 2315 may also include an elastic sheet or an elastic block.

[0091] Reference Figure 6-Figure 8 The adjusting assembly 23 further includes a sliding assembly 234 , and the plurality of mounting seats 22 are respectively slidably connected to the mounting plate 21 via the plurality of sliding assemblies 234 . The sliding assembly 234 includes a guide rail 2341 and a slider 2342 .

[0092] Reference Figure 6-Figure 8 Specifically, the guide rail 2341 is mounted on the mounting plate 21, the slider 2342 is slidably fitted on the guide rail 2341, and the mounting seat 22 is fixed to the slider 2342. The mounting seat 22 is slidably mounted on the mounting plate 21 by the cooperation between the guide rail 2341 and the slider 2342, thereby improving the sliding accuracy of the mounting seat 22.

[0093] Reference Figure 6-Figure 8 Furthermore, the top surface of the mounting plate 21 is provided with a plurality of recessed grooves, and the guide rails 2341 are mounted at the bottom of the recessed grooves. The recessed groove design accommodates the guide rails 2341 and the sliders 2342, making rational use of the space on the mounting plate 21. The guide rails 2341 and the sliders 2342 are unlikely to interfere with the arrangement of other structures on the mounting plate 21.

[0094] Reference Figure 7-Figure 9 , wherein the sliding assembly 234 further includes a sliding mounting structure 2343 , and the guide rail 2341 is mounted on the mounting plate 21 through the sliding mounting structure 2343 .

[0095] Reference Figure 7-Figure 9Specifically, the sliding mounting structure 2343 includes a plurality of guide rail threaded holes 23431, a plurality of guide rail mounting holes 23432, and a plurality of guide rail connecting bolts 23433. The plurality of guide rail threaded holes 23431 are all provided on the mounting plate 21 and are spaced apart in the second direction. The plurality of guide rail mounting holes 23432 are all provided on the guide rail 2341 and are spaced apart in the longitudinal direction of the guide rail 2341. The plurality of guide rail mounting holes 23432 are provided in a one-to-one correspondence with the plurality of guide rail threaded holes 23431. The plurality of guide rail connecting bolts 23433 respectively pass through the plurality of guide rail mounting holes 23432 and are respectively threadedly engaged with the plurality of guide rail threaded holes 23431. The heads of the guide rail connecting bolts 23433 are tightly pressed against the guide rail 2341.

[0096] With this arrangement, the guide rail 2341 can be fixed to the mounting plate 21 by tightening the guide rail connecting bolt 23433 so that the head of the guide rail connecting bolt 23433 is pressed against the guide rail 2341 .

[0097] Furthermore, the diameter of the threaded section of the guide rail connecting bolt 23433 is smaller than the diameter of the guide rail mounting hole 23432. When the guide rail connecting bolt 23433 has not yet abutted against the guide rail 2341, the guide rail 2341 can move relative to the mounting plate 21, i.e., it can be adjusted to move the guide rail 2341 in the first direction, or it can be driven to rotate in the horizontal plane to change the length direction of the guide rail 2341, ensuring that the length direction of the guide rail 2341 is consistent with the length direction of the nozzle holes of the nozzle head 24.

[0098] With this arrangement, after the mounting base 22 is mounted on the slider 2342, the length direction and the position of the guide rail 2341 in the second direction are adjusted to ensure that the nozzle holes of the multiple nozzles 24 are aligned in the length direction, thereby ensuring that the nozzle holes of the multiple nozzles 24 can be interpolated. In other embodiments, the length direction of the nozzle holes of the multiple nozzles 24 can also be aligned to ensure that the nozzle holes of the multiple nozzles 24 can be spliced in the length direction of the nozzle holes.

[0099] It is important to note that the differences in the positions of the multiple nozzles 24 in the first direction and the lengthwise arrangement of the nozzle holes of the multiple nozzles 24 are small, at the micron level, and can be corrected with only fine-tuning. Therefore, the gap between the guide rail connecting bolt 23433 and the wall of the guide rail mounting hole 23432 is sufficient for fine-tuning.

[0100] Reference Figure 6-Figure 8 , wherein the adjustment component 23 further includes a second adjustment structure 232 , and the second adjustment structure 232 includes a second fixing seat 2321 and at least two second pushing members 2322 .

[0101] Reference Figure 6-Figure 8Specifically, the second fixing seat 2321 is fixed to the mounting plate 21. A plurality of second pushing members 2322 are mounted on the second fixing seat 2321. The plurality of second pushing members 2322 are spaced apart in the second direction, and the pushing ends of the second pushing members 2322 move along the first direction. The pushing ends of the second pushing members 2322 are used to push the adjustment seat 2313 to move in the first direction, thereby driving the mounting seat 22 and the guide rail 2341 to move in the first direction.

[0102] When adjusting the position of the nozzle 24 in the first direction, loosen the guide rail connecting bolt 23433, and then synchronously make multiple second push members 2322 drive the adjustment seat 2313 to move in the first direction. At this time, the adjustment seat 2313, the mounting seat 22, the guide rail 2341 and the nozzle 24 all move in the first direction to change the position of the nozzle 24 in the first direction.

[0103] To adjust the length of the nozzle holes of the nozzle 24, loosen the guide rail connecting bolt 23433, then use the second push member 2322, whose point of action is close to the edge of the adjustment seat 2313, to push the adjustment seat 2313. The adjustment seat 2313 is then subjected to uneven force, causing it to rotate horizontally, thereby driving the adjustment seat 2313, the mounting seat 22, the guide rail 2341, and the nozzle 24 to rotate synchronously. This allows the nozzle holes of the nozzle 24 to be adjusted in length, ensuring that the nozzle holes of multiple nozzles 24 are aligned in length.

[0104] Furthermore, when adjusting the position of the nozzle 24 in the first direction and adjusting the length direction of the arrangement of the nozzle holes of the nozzle 24, the guide rail connecting bolt 23433 is in a pre-tightened state, that is, the head of the guide rail connecting bolt 23433 abuts against the guide rail 2341. At this time, there is friction between the guide rail connecting bolt 23433 and the guide rail 2341, thereby increasing the damping of the movement of the guide rail 2341 relative to the mounting plate 21. At this time, the second push-out member 2322 pushes the adjustment seat 2313 so that when the mounting seat 22 and the guide rail 2341 move, the adjustment seat 2313, the mounting seat 22 and the guide rail 2341 are less affected by inertia, and the movement distance of the adjustment seat 2313, the mounting seat 22 and the guide rail 2341 is more controllable, thereby improving the accuracy of the position adjustment of the nozzle 24.

[0105] Reference Figure 6-Figure 8 In this embodiment, two second ejecting members 2322 are provided, and the ejecting positions of the two second ejecting members 2322 are respectively arranged close to two opposite edges of the adjustment seat 2313. The second ejecting member 2322 is preferably a micrometer head.

[0106] Reference Figure 6-Figure 8 Furthermore, a plurality of avoidance holes 22a are provided on the top surface of the mounting seat 22, and the avoidance holes 22a are arranged through, and the plurality of avoidance holes 22a are respectively arranged opposite to the plurality of guide rail mounting holes 23432 in the upper and lower directions.

[0107] With this arrangement, when it is necessary to adjust the position of the nozzle 24 in the first direction or to adjust the length direction of the nozzle hole arrangement of the nozzle 24, an external tool can be passed through the clearance hole 22a to loosen the guide rail connecting bolt 23433. After the position adjustment of the nozzle 24 is completed, the external tool can also be passed through the clearance hole 22a to tighten the guide rail connecting bolt 23433 to fix the position of the guide rail 2341, thereby facilitating the adjustment operation of the position of the nozzle 24.

[0108] Reference Figure 6-Figure 8 The adjustment assembly 23 further includes multiple sets of third adjustment structures 233, which are respectively provided at the corners of the top surface of the mounting base 22. The third adjustment structures 233 adjust the height of the mounting base 22. The third adjustment structures 233 include a first adjustment bolt 2331 and a second adjustment bolt 2332.

[0109] Reference Figure 6-Figure 8 Specifically, the first adjusting bolt 2331 passes through the mounting seat 22 and is threadedly connected to the slider 2342, and the head of the first adjusting bolt 2331 is tightly against the mounting seat 22. The second adjusting bolt 2332 is threadedly provided in the mounting seat 22 and is tightly against the slider 2342.

[0110] In this configuration, the height of the nozzle 24 relative to the mounting plate 21 is adjusted by adjusting the gap between the mounting seat 22 and the slider 2342 by screwing the first adjusting bolt 2331 and the second adjusting bolt 2332 .

[0111] The second adjustment bolts 2332 abut against the slider 2342, allowing the mounting base 22 to be supported on the slider 2342 via the multiple second adjustment bolts 2332, leaving a gap between the mounting base 22 and the top surface of the slider 2342. The first adjustment bolt 2331 is threadedly connected to the slider 2342. Tightening the first adjustment bolt 2331 reduces the gap between the slider 2342 and the mounting base 22. By pushing and pulling the first and second adjustment bolts 2331 and 2332, the height of the mounting base 22 relative to the slider 2342 can be precisely adjusted, thereby adjusting the height of the nozzle 24 relative to the mounting plate 21. This ensures that the heights of the nozzles 24 are consistent, and that the heights of the ejection surfaces of the nozzles 24 are consistent, ensuring printing consistency and improving printing accuracy.

[0112] By using multiple sets of third adjustment structures 233 to adjust the height of different positions of the mounting base 22, the horizontality of the ejection surface of the nozzle 24 on the mounting base 22 can be adjusted to ensure that the ejection surface of the nozzle 24 is set horizontally, thereby improving printing accuracy.

[0113] Reference Figure 6-Figure 8Furthermore, the sliding assembly 234 also includes a connecting plate 2344, which is fixed to the top surface of the slider 2342. The connecting plate 2344 replaces the slider 2342 and is connected to the third adjustment structure 233, that is, the first adjusting bolt 2331 is threadedly connected to the connecting plate 2344, and the second adjusting bolt 2332 is pressed against the connecting plate 2344.

[0114] With this arrangement, when the first adjusting bolt 2331 and the second adjusting bolt 2332 are turned to change the height of the mounting base 22, the first adjusting bolt 2331 and the second adjusting bolt 2332 both apply force to the connecting plate 2344. Due to the blocking effect of the connecting plate 2344, the slider 2342 is not easily slightly deformed due to the force, thereby ensuring the sliding accuracy of the slider 2342.

[0115] In this embodiment, after the nozzle 24 is installed on the mounting plate 21 along with the mounting base 22, the second adjustment structure 232 is first used to adjust the position of the nozzle 24 in the first direction and the length direction of the arrangement of the nozzle holes of the nozzle 24 to ensure that the arrangement length direction of the nozzle holes of all nozzles 24 is consistent. The position of the nozzle 24 in the second direction is then changed by the first adjustment structure 231, so that the nozzle holes of multiple nozzles 24 can form an interpolation fit. Subsequently, the height of the mounting base 22 is adjusted using the third adjustment structure 233 to adjust the height of the nozzle 24 to ensure that the ejection surface of the nozzle 24 is horizontal and the ejection surface heights of multiple nozzles 24 are consistent. In this embodiment, the adjustment component 23 has a high degree of integration and can achieve precise fine-tuning of the nozzle 24 in multiple directions to ensure printing accuracy.

[0116] In summary, multiple nozzles 24 can be precisely and seamlessly spliced into a nozzle module 2. After the multiple nozzles 24 are seamlessly spliced into the nozzle module 2, the multiple nozzle modules 2 can be spliced into a printing module to improve the splicing efficiency of the printing module. It should be noted that the nozzle module 2 can be spliced in advance to facilitate the subsequent assembly of the printing module. In this embodiment, the printing resolution of the spliced nozzle module 2 is high, which supports the demand for high-resolution printing.

[0117] When multiple nozzle modules 2 are assembled into a printing module, the nozzle holes of the multiple nozzle modules 2 are interpolated and matched, and / or the nozzle holes of the multiple nozzle modules 2 are evenly spaced in the same direction to increase the nozzle hole arrangement length and thus the unit printing length. In this embodiment, the nozzle holes of the multiple nozzle modules 2 are evenly spaced in the same direction to meet the requirements of high-resolution printing on large substrates, thereby improving printing efficiency.

[0118] Reference Figure 2 and Figure 3The bottom plate 11 of the base 1 is provided with a plurality of through-grooves 11a. The plurality of nozzle modules 2 are mounted in the plurality of mounting grooves 11a, respectively, with the bottoms of the nozzle modules 2 positioned within the mounting grooves 11a or extending below the mounting grooves 11a. In this embodiment, the bottoms of the nozzle modules 2 extend below the mounting grooves 11a, meaning that the ejection surfaces of the nozzles 24 in the nozzle modules 2 are located below the bottom plate 11.

[0119] With this arrangement, the ejection surface of the nozzle 24 is lower than the bottom plate 11 . During printing, the bottom plate 11 does not interfere with the descent of the nozzle module 2 , and cleaning and maintenance of the ejection surface of the nozzle 24 are facilitated.

[0120] Reference Figure 2 and Figure 3 The mounting plate 21 of the nozzle module 2 is connected to the base plate 11 via multiple fixing assemblies 4. These fixing assemblies 4 are located at the corners of the bottom surface of the mounting plate 21. In this embodiment, the mounting plate 21 is square, and each nozzle module 2 corresponds to four fixing assemblies 4. These four fixing assemblies 4 respectively secure the four corners of the mounting plate 21 to the base plate 11 and adjust the height of the corners of the mounting plate 21 relative to the base plate 11.

[0121] With this arrangement, the height of multiple corners of the mounting plate 21 of the nozzle module 2 is adjusted respectively by multiple fixing components 4, so as to facilitate adjusting the ejection surface of the nozzle module 2 to be horizontal, and the installation position of the nozzle module 2 is not affected by the horizontality of the base plate 11.

[0122] Reference Figure 10-12 Specifically, the fixing assembly 4 includes a threaded sleeve 41 and a fixing bolt 42. The threaded sleeve 41 is vertically inserted through the base plate 11 and is threadedly connected to the base plate 11. The top end of the threaded sleeve 41 abuts against the mounting plate 21 to support the mounting plate 21. The fixing bolt 42 is inserted through the threaded sleeve 41 and is threadedly connected to the mounting plate 21. The head of the fixing bolt 42 abuts against the bottom end surface of the threaded sleeve 41.

[0123] With this arrangement, the mounting plate 21 is supported by a plurality of threaded sleeves 41. By adjusting the height of the top surface of the threaded sleeves 41 to adjust the height of different corners of the mounting plate 21, the ejection surface of the nozzle module 2 can be adjusted to a horizontal state. Since the mounting plate 21 is supported by the threaded sleeves 41, the deformation of the base plate 11 due to the load will not affect the installation of the nozzle module 2. In addition, by tightening the fixing bolts 42 so that the heads of the fixing bolts 42 are pressed against the bottom end surface of the threaded sleeves 41, the mounting plate 21 can be pressed against the threaded sleeves 41. By tightening the fixing bolts 42, the installation accuracy of the contact points between the mounting plate 21 and the plurality of threaded sleeves 41 can be further ensured, and the height of the ejection surface of the nozzle module 2 can be ensured to be horizontal by adjusting the height of each part of the mounting plate 21.

[0124] Reference Figure 10-12 In addition, each nozzle module 2 is height-adjustable through a plurality of threaded sleeves 41 and a plurality of fixing bolts 42 , making it convenient to adjust the ejection surfaces of the plurality of nozzle modules 2 to a consistent height without being affected by the deformation of the base plate 11 .

[0125] Reference Figure 10-12 Furthermore, the fixing assembly 4 further includes a locking nut 43. The locking nut 43 is disposed near the bottom of the threaded sleeve 41, and the locking nut 43 is sleeved on the threaded sleeve 41 and threadedly connected to the threaded sleeve 41. The top surface of the locking nut 43 is tightly pressed against the bottom plate 11.

[0126] With this arrangement, after adjusting the threaded sleeve 41 and the fixing bolt 42, the locking nut 43 is tightened until the locking nut 43 is pressed against the base plate 11. This secures the threaded sleeve 41 to the base plate 11, making it less susceptible to rotation due to external forces and maintaining its position relative to the base plate 11. During printing, when the nozzle 24 module moves, the threaded sleeve 41 will not become loose, thereby ensuring the horizontality of the ejection surface of the nozzle module 2 and the height consistency of the ejection surfaces of multiple nozzle modules 2.

[0127] It should be noted that after multiple nozzle modules 2 are installed, due to the differences in installation accuracy and the horizontality accuracy of the bottom plate 11 of the base 1, the height difference of the ejection surfaces of the multiple nozzle modules 2 and the inclination angle of the ejection surface of a single nozzle module 2 are relatively small, usually at the micron level. By adjusting the combination of the threaded sleeve 41 and the fixing bolt 42, the horizontality of the ejection surface of the nozzle module 2 and the height difference of the ejection surfaces of the multiple nozzle modules 2 can be corrected.

[0128] Furthermore, ear plates 21 a are provided at the corners of the mounting plate 21 , the threaded sleeves 41 abut against the bottom surfaces of the ear plates 21 a , and the fixing bolts 42 are threadedly connected to the ear plates 21 a .

[0129] With this arrangement, the threaded sleeve 41 and the fixing bolt 42 both apply force to the ear plate 21a, so that the main part of the mounting plate 21 is not easily deformed by the force, thereby maintaining the normal state of the nozzle module 2. The nozzle module 2 is not easily deformed, ensuring that the relative position and height consistency of the nozzle 24 in the nozzle module 2 remain unchanged.

[0130] Reference Figure 10-12 Optionally, the bottom surface of the base plate 11 is provided with a plurality of receiving holes 11b, and the threaded sleeves 41 and the fixing bolts 42 are both inserted into the bottoms of the receiving holes 11b. The locking nuts 43 are tightened against the bottoms of the receiving holes 11b. The bottoms of the threaded sleeves 41 and the fixing bolts 42 are both located within the receiving holes 11b.

[0131] In this way, the arrangement of the accommodating hole 11b allows the threaded sleeve 41 and the fixing bolt 42 to be hidden, and the bottom ends of the threaded sleeve 41 and the fixing bolt 42 are higher than the bottom surface of the base plate 11. The base plate 11 protects the threaded sleeve 41 and the fixing bolt 42 to prevent the threaded sleeve 41 and the fixing bolt 42 from being loosened due to collision, thereby ensuring that the height position of the nozzle module 2 remains unchanged.

[0132] Reference Figure 10-12 Optionally, fixing assembly 4 further includes a protective cover 44 . Protective cover 44 is provided corresponding to the plurality of receiving holes 11 b . Protective cover 44 is secured to the bottom surface of base plate 11 via screws, with the centerline of protective cover 44 perpendicular to the bottom surface of base plate 11 . Protective cover 44 communicates with receiving holes 11 b . External tools can pass through protective cover 44 to operate fixing bolts 42 .

[0133] With this arrangement, the protective cover 44, on the one hand, blocks the accommodating hole 11b, reducing the risk of external debris entering the accommodating hole 11b and contaminating the threaded sleeve 41, the fixing bolt 42 and the lock nut 43; on the other hand, the protective cover 44 allows external tools to pass through to operate the fixing bolt 42. By adjusting the fixing bolt 42 separately, the degree of contact between the mounting plate 21 and the threaded sleeve 41 can be changed without removing the protective cover 44, so as to fine-tune the height of the mounting plate 21.

[0134] Reference Figure 2 and Figure 3 , wherein the multiple groups of correcting components 3 act on the multiple nozzle modules 2 respectively, and the correcting components 3 are installed on the bottom plate 11 to adjust the length direction of the nozzle hole arrangement of the nozzle module 2.

[0135] Reference Figure 10 、 Figure 13 and Figure 14 The deflection correction assembly 3 includes a rotational shaft 31 and a deflection correction ejection member 32. The nozzle module 2 is rotatably connected to the base plate 11 via the rotational shaft 31, and the nozzle module 2 rotates in the horizontal plane. The deflection correction ejection member 32 pushes the nozzle module 2, causing it to rotate and adjust the lengthwise arrangement of the nozzles 24 of the nozzle module 2.

[0136] Specifically, a hinge hole is opened on the mounting plate 21 of the nozzle module 2, and the rotating shaft 31 is vertically fixed to the base plate 11, and the rotating shaft 31 passes through the hinge hole and is arranged in the mounting plate 21, so that the nozzle module 2 is rotatably connected to the base plate 11.

[0137] The deflection correcting push piece 32 and the rotating shaft 31 are respectively arranged near two opposite side surfaces of the nozzle module 2 in the second direction, and the deflection correcting push piece 32 and the rotating shaft 31 are staggered in the first direction. The deflection correcting push piece 32 pushes the nozzle module 2 toward the second direction.

[0138] When the nozzle module 2 is installed on the base 1, due to the installation accuracy error, the length direction of the arrangement of the nozzle holes of multiple nozzle modules 2 is not completely consistent, and there will be some deviation. The correction component 3 is used to fine-tune the length direction of the arrangement of the nozzle holes of the nozzle module 2 to ensure that the length direction of the arrangement of the nozzle holes of multiple nozzle modules 2 is consistent.

[0139] The deflection-correcting pushing member 32 is installed on the base 1 , and the pushing end of the deflection-correcting pushing member 32 moves toward the second direction to push the nozzle module 2 to rotate.

[0140] Because the deflection-correcting ejection member 32 and the rotation axis 31 are staggered in the first direction, when the deflection-correcting ejection member 32 pushes the printhead module 2, the thrust applied by the top end of the deflection-correcting ejection member 32 to the printhead module 2 does not pass through the center line of the rotation axis 31, thereby ensuring that the printhead module 2 can be pushed to rotate around the rotation axis 31.

[0141] In this embodiment, the ear plate 21 a on the mounting plate 21 of the nozzle module 2 is located on the side of the mounting plate 21 , and the deviation correcting and pushing member 32 pushes the ear plate 21 a to drive the nozzle module 2 to rotate around the rotation axis 31 .

[0142] Reference Figure 10 and Figure 12 In addition, in order to ensure the threaded connection between the fixing bolt 42 and the mounting plate 21, a gap is left between the circumferential outer side surface of the screw portion of the fixing bolt 42 and the circumferential inner side surface of the threaded sleeve 41. When the fixing bolt 42 is connected to the mounting plate 21, the fixing bolt 42 can rotate with the mounting plate 21, and the screw portion of the fixing bolt 42 moves in the threaded sleeve 41.

[0143] With this arrangement, before adjusting the length direction of the nozzle arrangement of the nozzle module 2, the fixing bolt 42 is first connected to the mounting plate 21, and the threaded sleeve 41 is against the bottom of the mounting plate 21. At this time, the fixing bolt 42 and the threaded sleeve 41 are both in a pre-tightened state, that is, the mounting plate 21 can move relative to the threaded sleeve 41. The pre-tightened state of the threaded sleeve 41 and the fixing bolt 42 increases the friction between the mounting plate 21 and the threaded sleeve 41, making the damping of the movement of the mounting plate 21 greater. As the deviation correction push member 32 pushes the nozzle module 2 to rotate, the nozzle module 2 is less affected by inertia, and the rotational movement of the nozzle module 2 is more precise and controllable, which facilitates and accurately adjusts the nozzle arrangement direction of the nozzle module 2, and ensures that the nozzle arrangement directions of multiple nozzle modules 2 are consistent.

[0144] After the arrangement direction of the spray holes of the spray head module 2 is adjusted, the fixing bolt 42 and the threaded sleeve 41 are then engaged to precisely adjust the levelness and height of the spray surface of each spray head module 2 .

[0145] Reference Figure 10 、 Figure 13 and Figure 14Furthermore, a plurality of deflection correcting push members 32 are provided, and the plurality of deflection correcting push members 32 are spaced apart in the first direction. In this embodiment, two deflection correcting push members 32 are provided, and the two deflection correcting push members 32 act on the two ear plates 21a on one side of the mounting plate 21 respectively.

[0146] With this arrangement, multiple correcting push members 32 are used to apply force to different positions of the nozzle module 2 to achieve rotation of the nozzle module 2 in different directions. The arrangement length direction of the nozzles 24 of the nozzle module 2 can be adjusted more freely and with higher adjustment efficiency.

[0147] Furthermore, the diameter of the rotating shaft 31 is smaller than the aperture of the hinge hole, and the multiple deviation-correcting pushing members 32 push the nozzle module 2 synchronously to make the nozzle module 2 move in the second direction.

[0148] With this arrangement, the nozzle module 2 is pushed to move in the second direction by multiple correcting push members 32 to fine-tune the position of the nozzle module 2 in the second direction, ensuring that after the multiple nozzle modules 2 are assembled, the nozzle holes of all the nozzle modules 2 are evenly spaced in the second direction, thereby achieving seamless splicing of the multiple nozzle modules 2, increasing the unit printing length of the printing module, and improving printing efficiency.

[0149] In this embodiment, the deviation-correcting ejection member 32 includes a micrometer head, which has high adjustment accuracy and reduces the difficulty of fine-tuning the position of the nozzle module 2.

[0150] It should be noted that when the nozzle module 2 is installed on the base 1 and placed in the designated position, due to installation precision errors, the nozzle orifice arrangement length direction of multiple nozzle modules 2 is inconsistent, and the directional deviation is small, less than 1 degree. Furthermore, the installation position deviation of multiple nozzle modules 2 in the second direction is also small, at the micron level. Therefore, by using the correction push member 32 to drive the nozzle module 2 to rotate a small angle, the error in the nozzle orifice arrangement direction can be corrected; by using the correction push member 32 to drive the nozzle module 2 to move as a whole in the second direction, the installation error of the nozzle module 2 in the second direction can be corrected.

[0151] Reference Figure 10 、 Figure 13 and Figure 14 Furthermore, the deflection correction assembly 3 further includes a protective shell 33, which is connected to the nozzle module 2, and the pushing end of the deflection correction ejection member 32 is adapted to push the protective shell 33. In this embodiment, the protective shell 33 is fixed to the ear plate 21a by screws, so that the deflection correction ejection member 32 can apply force.

[0152] In this arrangement, the protective shell 33 is used instead of the nozzle module 2 to bear the force, thereby avoiding damage to the nozzle module 2 during the assembly process. If the protective shell 33 is deformed or even broken due to multiple pushes, it is also convenient to continue to protect the force-bearing part of the nozzle module 2 by replacing the protective shell 33.

[0153] The embodiment of the present application provides a printing module for large-sized substrates. The printing module is composed of a plurality of nozzle modules 2, each of which is composed of a plurality of nozzles 24. The plurality of nozzles 24 in the nozzle module 2 are seamlessly spliced together, so that the nozzle holes of the plurality of nozzles 24 in the nozzle module 2 are interpolated, and then the plurality of nozzle modules 2 are seamlessly spliced together. Therefore, when the plurality of nozzles 24 are spliced together to form a printing module, it is only necessary to further splice the plurality of seamlessly spliced nozzle modules 2 and adjust the installation positions of the plurality of nozzle modules 2. This can simultaneously adjust the installation positions of the plurality of nozzles 24, thereby improving the assembly efficiency of the printing module.

[0154] When the multiple nozzles 24 in the nozzle module 2 are spliced together, the positions of the multiple nozzles 24 are adjusted respectively by using multiple adjustment components 23, and the nozzles 24 are slid in the second direction to fine-tune the relative positions of the multiple nozzles 24 to eliminate the position deviation caused by the installation accuracy of the nozzles 24, so as to ensure the printing accuracy and enable the nozzle holes of the multiple nozzles 24 to be interpolated.

[0155] When assembling multiple nozzle modules 2, the deflection correction assembly 3 is used to adjust the position of the nozzle modules 2 so that the nozzle holes in the multiple nozzle modules 2 are aligned in length. This deflection correction assembly 3 eliminates precision errors during installation of the nozzle modules 2, enabling high-precision splicing of the nozzle modules 2 to ensure printing accuracy. Deflection correction of the nozzle module 2 simultaneously corrects the deflection of multiple nozzles 24, improving the efficiency of deflection correction and assembly of the nozzles 24.

[0157] Another embodiment of the present application provides a printing device.
