Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a multi-nozzle splicing printing module, a nozzle module and a printing equipment. 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 device is the inkjet printing unit. Under the drive of the drive shaft, the inkjet printing unit realizes full-size printing of the printed substrate through multiple reciprocating motions of the drive shaft. The traditional inkjet printing unit is generally equipped with one nozzle a. In order to further improve the printing resolution, it is necessary to further configure multiple nozzles a to print in sequence. Figure 1 The multiple nozzle holes of the rear nozzle head a and the multiple nozzle holes of the front nozzle head are interpolated in the arrangement direction of the multiple nozzle heads a to increase the density of the printing ink droplets, thereby improving the printing resolution.

[0004] In addition, in order to adapt to the need to print large-size substrates, it is necessary to splice multiple nozzles a in the length direction of the nozzle arrangement to increase the length of the substrate printed by the inkjet printing unit each time. Figure 2 . To speed up the printing efficiency of the substrate.

[0005] In related art, the nozzles are mounted on a mounting plate attached to a base, which is then connected to the base using bolts. The diameter of the through-holes in the mounting plate through which the bolts pass is larger than the diameter of the bolts. This allows for adjustment of the mounting plate, allowing for fine-tuning of the relative position of the mounting plate and base, and thereby fine-tuning the relative positions of multiple nozzles. By adaptively adjusting the positions of the multiple nozzles in the direction of nozzle arrangement, the nozzles of the rear nozzle can be interpolated with those of the front nozzle, or the nozzles of multiple nozzles can be arranged in the same direction.

[0006] However, the spacing between the nozzles in a printhead is minute, reaching the micron level. If the printhead position is manually adjusted by sliding the mounting plate to meet interpolation printing or lengthen the nozzle arrangement, the adjustment distance is difficult to control and the adjustment accuracy is poor. Even if the printhead position adjustment requirements can be achieved, the adjustment efficiency is extremely low. Summary of the Invention

DETAILED DESCRIPTION

[0052] 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.

[0053] The embodiments of the present application provide a multi-nozzle splicing printing module, a nozzle module and a printing device. The multi-nozzle splicing printing module adjusts the positions of multiple mounting seats and multiple nozzles relative to the carrier plate through multiple adjustment components to achieve interpolation of multiple nozzle holes of multiple nozzles, and can also achieve uniform spacing of multiple nozzle holes of multiple nozzles in the same direction. It can more precisely drive the movement of the mounting seat and the nozzle, facilitate the control of the adjustment distance of the nozzle, and has high adjustment efficiency and adjustment accuracy, meeting the requirements of interpolation printing of multiple nozzles or lengthening the arrangement length of the nozzle holes. The present application solves the technical problems in the related art that the adjustment distance of the nozzle position is difficult to control, the adjustment accuracy is poor, and the adjustment efficiency is extremely low.

[0054] Reference Figure 3-Figure 5 A multi-nozzle splicing printing module includes a carrier plate 1, multiple mounting blocks 2, and multiple adjustment assemblies 3. The nozzles a are fixed to the mounting blocks 2, which are mounted on the carrier plate 1. The multiple adjustment assemblies 3 correspond to the multiple mounting blocks 2 and adjust the positions of the multiple mounting blocks 2 relative to the carrier plate 1, so that the multiple nozzles a can be spliced and mounted on the carrier plate 1 as required.

[0055] Reference Figure 3-Figure 5Specifically, the carrier plate 1 has multiple through-holes through which nozzle a passes. After nozzle a is secured to the mounting base 2, the bottom end of nozzle a passes through the through-holes to avoid interfering with the nozzle holes at the bottom of nozzle a. Mounting base 2 is connected to the top surface of the carrier plate 1, and an adjustment assembly 3 adjusts the installation position of mounting base 2.

[0056] The positions of the multiple mounting seats 2 and the multiple nozzles a relative to the supporting plate 1 are adjusted by multiple adjustment components 3 to achieve interpolation of the multiple nozzle holes of the multiple nozzles a, and also to achieve uniform spacing of the multiple nozzle holes of the multiple nozzles a in the same direction.

[0057] Reference Figure 3-Figure 5 The mounting base 2 includes a horizontal portion and a vertical portion, and is generally L-shaped. The nozzle a is fixed to the vertical portion of the mounting base 2, and the horizontal portion of the mounting base 2 is connected to the bearing plate 1.

[0058] Reference Figure 5 and Figure 6 Specifically, the mounting base 2 is slidably mounted on the supporting plate 1, the sliding direction of the mounting base 2 is arranged along the first direction, and the longitudinal direction of the arrangement of the plurality of nozzle holes of the nozzle head a on the mounting base 2 is arranged along the first direction. For ease of understanding, the first direction is the X-axis direction in the figure.

[0059] With this arrangement, the position of the nozzle a relative to the carrier plate 1 can be changed by sliding the mounting base 2. This facilitates interpolation of the nozzle holes of the multiple nozzles a. In addition, it also facilitates aligning the spacing between the nozzle holes of adjacent nozzles a with the spacing of the nozzle holes on the nozzle a. This ensures that the spacing of the nozzle holes of the multiple nozzles a after splicing is consistent in the first direction. This allows for precise splicing of the multiple nozzles a. The nozzle hole arrangement length of the printing module after splicing the multiple nozzles a is longer, making it suitable for printing processing on large-sized substrates and improving processing efficiency.

[0060] Reference Figure 5 and Figure 6 , wherein the adjustment assembly 3 includes a first adjustment structure 31. The first adjustment structure 31 includes a first fixed seat 311, a first ejecting member 312, and an adjustment seat 313. Part of the first fixed seat 311 is fixed to the supporting plate 1, and part of the first fixed seat 311 is detachably connected to the mounting seat 2. The adjustment seat 313 is fixed to the mounting seat 2, and the first ejecting member 312 is mounted on the first fixed seat 311. The ejecting end of the first ejecting member 312 is adapted to move in a first direction, and the ejecting end of the first ejecting member 312 is adapted to push the adjustment seat 313.

[0061] Specifically, a portion of the first fixing seat 311 is fixed to the support plate 1 via bolts. To adjust the position of nozzle a by moving the nozzle a in the lengthwise direction of its nozzle holes, the first fixing seat 311 is first released from its fixed state with the mounting seat 2. The top end of the first pushing member 312 pushes the adjustment seat 313 in the first direction, thereby synchronously driving the mounting seat 2 and the nozzle a to move in the first direction, thereby adjusting the position of nozzle a. After the position adjustment of nozzle a is completed, the first fixing seat 311 is fixed to the mounting seat 2. At this time, the mounting seat 2, the first fixing seat 311, and the support plate 1 are fixed together, restricting the movement of the mounting seat 2 relative to the support plate 1, thereby fixing the position of nozzle a relative to the support plate 1.

[0062] With this arrangement, the first push member 312 is used to push the adjustment seat 313 to change the movement form of the nozzle a, and the movement accuracy is more controllable. Compared with directly sliding the nozzle a by hand, the accuracy is higher and the movement distance is more controllable, thereby improving the accuracy of adjusting the position of the nozzle a and improving the adjustment efficiency of the splicing position of the nozzle a.

[0063] In this embodiment, the first ejecting member 312 includes a micrometer head.

[0064] Reference Figure 5-Figure 7 The first adjustment structure 31 further includes a first connecting structure 314, through which the first fixing seat 311 and the mounting seat 2 are detachably connected. The first connecting structure 314 includes a first threaded hole 3141, a first mounting hole 3142, and a first connecting bolt 3143. The first threaded hole 3141 is provided on the top surface of the mounting seat 2, the first mounting hole 3142 is provided in the first fixing seat 311, and the first mounting hole 3142 is provided through the first fixing seat 311. The first connecting bolt 3143 passes through the first mounting hole 3142 and is threadedly engaged with the first threaded hole 3141. The head of the first connecting bolt 3143 is tightly pressed against the first fixing seat 311. The diameter of the threaded section of the first connecting bolt 3143 is smaller than the diameter of the first mounting hole 3142.

[0065] With this arrangement, by tightening the first connecting bolt 3143, the head of the first connecting bolt 3143 is pressed against the first fixing seat 311, thereby fixing the mounting seat 2 to the first fixing seat 311. When the first ejector 312 is needed to adjust the position of the nozzle a, the first connecting bolt 3143 is loosened. Since the diameter of the threaded section of the first connecting bolt 3143 is smaller than the diameter of the first mounting hole 3142, the first connecting bolt 3143 can move relative to the first fixing seat 311, and thus the mounting seat 2 can move relative to the first fixing seat 311. At this time, the first ejector 312 can drive the adjustment seat 313 and the mounting seat 2 to move relative to the first fixing seat 311 and the supporting plate 1, thereby adjusting the position of the nozzle a.

[0066] When the first ejection member 312 is used to adjust the position of the nozzle a, the first connecting bolt 3143 can be pre-tightened, that is, the head of the first connecting bolt 3143 abuts against the first fixing seat 311. At this time, friction is generated between the head of the first connecting bolt 3143 and the first fixing seat 311. This increases the damping of the movement of the mounting seat 2 relative to the first fixing seat 311. At this time, when the first ejection member 312 pushes the adjustment seat 313 and the mounting seat 2 to move, the adjustment seat 313 and the mounting seat 2 are less affected by inertia, and the movement distance of the adjustment seat 313 and the mounting seat 2 is more controllable, thereby improving the accuracy of the adjustment of the nozzle a position.

[0067] It should be noted that the spacing between the multiple nozzles of nozzle a is small, at the micron level, so the gap between the first connecting bolt 3143 and the hole wall of the first mounting hole 3142 is sufficient to meet the position fine-tuning requirements of the mounting base 2.

[0068] Reference Figure 5 and Figure 6 Furthermore, the first adjustment structure 31 further includes an elastic member 315, and both ends of the elastic member 315 are respectively connected to the first fixing seat 311 and the adjustment seat 313. When the adjustment seat 313 moves away from the first fixing seat 311, the elastic member 315 is further stretched.

[0069] The position of the elastic member 315 ensures that the pushing top end of the first pushing member 312 remains in a tight state with the adjusting seat 313. Therefore, when the first pushing member 312 pushes the adjusting seat 313 to move, the movement distance of the pushing top end of the first pushing member 312 is ensured to be consistent with the movement distance of the adjusting seat 313, so as to facilitate the precise movement of the adjusting seat 313 by the specified distance, thereby improving the accuracy of the position adjustment of the nozzle a.

[0070] In addition, when the adjustment seat 313 is fixed away from the first fixed seat 311, the elastic member 315 is deformed to generate an elastic force between the adjustment seat 313 and the first fixed seat 311. The elastic force increases the damping of the movement of the mounting seat 2 relative to the first fixed seat 311. At this time, when the first push-up member 312 pushes the adjustment seat 313 and the mounting seat 2 to move, the adjustment seat 313 and the mounting seat 2 are less affected by inertia, and the movement distance of the adjustment seat 313 and the mounting seat 2 is more controllable, thereby improving the accuracy of adjusting the position of the nozzle a.

[0071] In this embodiment, the elastic member 315 includes a spring. In other embodiments, the elastic member 315 may also include an elastic sheet or an elastic block.

[0072] Reference Figure 5-Figure 7 The multi-nozzle splicing printing module further comprises a plurality of sliding assemblies 4, and the plurality of mounting seats 2 are respectively slidably connected to the carrier plate 1 through the plurality of sliding assemblies 4. The sliding assemblies 4 comprise guide rails 41 and sliders 42.

[0073] Reference Figure 6-Figure 8 Specifically, the guide rail 41 is mounted on the carrier plate 1, the slider 42 is slidably fitted on the guide rail 41, and the mounting base 2 is fixed to the slider 42. The mounting base 2 is slidably mounted on the carrier plate 1 by the cooperation between the guide rail 41 and the slider 42, thereby improving the sliding accuracy of the mounting base 2.

[0074] Reference Figure 5-Figure 7 Furthermore, the top surface of the carrier plate 1 is provided with a plurality of sunken grooves, and the guide rails 41 are mounted at the bottom of the grooves. The design of the sunken grooves accommodates the guide rails 41 and the sliders 42, making rational use of the space on the carrier plate 1. The guide rails 41 and the sliders 42 are unlikely to interfere with the arrangement of other structures on the carrier plate 1.

[0075] Reference Figure 6-Figure 8 , wherein the sliding assembly 4 further includes a sliding mounting structure 43 , and the guide rail 41 is mounted on the supporting plate 1 through the sliding mounting structure 43 .

[0076] Reference Figure 6-Figure 8 Specifically, the sliding mounting structure 43 includes a plurality of guide rail threaded holes 431, a plurality of guide rail mounting holes 432, and a plurality of guide rail connecting bolts 433. The plurality of guide rail threaded holes 431 are all provided on the bearing plate 1, and the plurality of guide rail threaded holes 431 are spaced apart in the first direction. The plurality of guide rail mounting holes 432 are all provided on the guide rail 41, and the guide rail mounting holes 432 are spaced apart in the length direction of the guide rail 41, and the plurality of guide rail mounting holes 432 are arranged in a one-to-one correspondence with the plurality of guide rail threaded holes 431. The plurality of guide rail connecting bolts 433 respectively pass through the plurality of guide rail mounting holes 432, and are respectively threadedly engaged with the plurality of guide rail threaded holes 431, and the heads of the guide rail connecting bolts 433 are pressed against the guide rail 41.

[0077] With this arrangement, the guide rail 41 can be fixed to the bearing plate 1 by tightening the guide rail connecting bolt 433 so that the head of the guide rail connecting bolt 433 is pressed against the guide rail 41 .

[0078] Furthermore, the diameter of the threaded section of the guide rail connecting bolt 433 is smaller than the diameter of the guide rail mounting hole 432. When the guide rail connecting bolt 433 is not yet tightened against the guide rail 41, the guide rail 41 can move relative to the carrier plate 1, thereby adjusting and driving the guide rail 41 to move in the second direction, or driving the guide rail 41 to rotate within the horizontal plane to change the longitudinal direction of the guide rail 41, ensuring that the longitudinal direction of the guide rail 41 is consistent with the longitudinal direction of the nozzle arrangement of the nozzles of the nozzle head a. In this embodiment, the second direction is perpendicular to the first direction. For ease of understanding, the second direction is the Y-axis direction in the figure.

[0079] With this arrangement, after the mounting base 2 is mounted on the slider 42, the length direction and the position of the guide rail 41 in the second direction can be adjusted to ensure that the nozzle holes of the multiple nozzles a are aligned in the length direction, thereby ensuring that the nozzle holes of the multiple nozzles a can be interpolated. Furthermore, the length direction of the nozzle holes of the multiple nozzles a can be aligned to ensure that the nozzle holes of the multiple nozzles a can be spliced in the length direction of the nozzle holes.

[0080] It is important to note that the differences in the positions of the multiple nozzles a in the second direction and the lengthwise arrangement of the nozzle holes of the multiple nozzles a are small, at the micron level, and can be corrected with only fine-tuning. Therefore, the gap between the guide rail connecting bolt 433 and the wall of the guide rail mounting hole 432 is sufficient for fine-tuning.

[0081] Reference Figure 5 and Figure 6 , wherein the adjustment component 3 further includes a second adjustment structure 32 , and the second adjustment structure 32 includes a second fixing seat 321 and at least two second ejecting members 322 .

[0082] Reference Figure 5 and Figure 6 Specifically, the second fixing seat 321 is fixed to the supporting plate 1. A plurality of second pushing members 322 are mounted on the second fixing seat 321. The plurality of second pushing members 322 are spaced apart in the first direction, and the pushing ends of the second pushing members 322 move along the second direction. The pushing ends of the second pushing members 322 are used to push the adjustment seat 313 to move in the second direction, thereby driving the mounting seat 2 and the guide rail 41 to move in the second direction.

[0083] When adjusting the position of the nozzle a in the second direction, loosen the guide rail connecting bolt 433, and then synchronously make multiple second push members 322 drive the adjustment seat 313 to move in the second direction. At this time, the adjustment seat 313, the mounting seat 2, the guide rail 41 and the nozzle a all move in the second direction to change the position of the nozzle a in the second direction.

[0084] To adjust the length of the nozzles of nozzle a, loosen the guide rail connecting bolts 433 and then push the second pusher 322, whose point of action is near the edge of the adjustment seat 313, against the adjustment seat 313. This causes uneven force on the adjustment seat 313, causing it to rotate horizontally, thereby driving the adjustment seat 313, the mounting seat 2, the guide rail 41, and the nozzle a to rotate synchronously. This allows the nozzles of nozzle a to be aligned in their length, ensuring that the nozzles of multiple nozzles a are aligned in their length.

[0085] Furthermore, when adjusting the position of nozzle a in the second direction and adjusting the length direction of the nozzle hole arrangement of nozzle a, the guide rail connecting bolt 433 is in a pre-tightened state, that is, the head of the guide rail connecting bolt 433 abuts against the guide rail 41. At this time, there is friction between the guide rail connecting bolt 433 and the guide rail 41, thereby increasing the damping of the movement of the guide rail 41 relative to the supporting plate 1. At this time, the second push-out member 322 pushes the adjustment seat 313 to make the mounting seat 2 and the guide rail 41 move. The adjustment seat 313, the mounting seat 2 and the guide rail 41 are less affected by inertia, and the movement distance of the adjustment seat 313, the mounting seat 2 and the guide rail 41 is more controllable, thereby improving the accuracy of the position adjustment of nozzle a.

[0086] Reference Figure 5 and Figure 6 In this embodiment, two second pushing members 322 are provided, and the pushing positions of the two second pushing members 322 are respectively arranged close to two opposite edges of the adjustment seat 313.

[0087] The second ejecting member 322 is preferably a micrometer head.

[0088] Reference Figure 6-Figure 8 Furthermore, a plurality of avoidance holes 2a are provided on the top surface of the mounting seat 2, and the avoidance holes 2a are arranged through, and the plurality of avoidance holes 2a are respectively arranged opposite to the plurality of guide rail mounting holes 432 in the upper and lower directions.

[0089] With this arrangement, when it is necessary to adjust the position of the nozzle a in the second direction or to adjust the length direction of the nozzle hole arrangement of the nozzle a, an external tool can be passed through the avoidance hole 2a to loosen the guide rail connecting bolt 433. After the position adjustment of the nozzle a is completed, the external tool can also be passed through the avoidance hole 2a to tighten the guide rail connecting bolt 433 to fix the position of the guide rail 41, thereby facilitating the adjustment operation of the position of the nozzle a.

[0090] Reference Figure 6-Figure 8 The adjustment assembly 3 further includes multiple sets of third adjustment structures 33, which are respectively provided at the corners of the top surface of the mounting base 2. The third adjustment structures 33 adjust the height of the mounting base 2. The third adjustment structures 33 include a first adjustment bolt 331 and a second adjustment bolt 332.

[0091] Reference Figure 6-Figure 8 Specifically, the first adjusting bolt 331 passes through the mounting seat 2 and is threadedly connected to the slider 42, and the head of the first adjusting bolt 331 is tightly against the mounting seat 2. The second adjusting bolt 332 is threadedly provided in the mounting seat 2, and the second adjusting bolt 332 is tightly against the slider 42.

[0092] In this configuration, the height of the nozzle a relative to the supporting plate 1 is adjusted by adjusting the gap between the mounting seat 2 and the slider 42 by screwing the first adjusting bolt 331 and the second adjusting bolt 332 .

[0093] The second adjustment bolts 332 abut against the slider 42, allowing the mounting base 2 to be supported on the slider 42 via the multiple second adjustment bolts 332, leaving a gap between the mounting base 2 and the top surface of the slider 42. The first adjustment bolts 331 are threadedly connected to the slider 42. Tightening the first adjustment bolts 331 reduces the gap between the slider 42 and the mounting base 2. By pushing and pulling the first and second adjustment bolts 331, 332 can precisely adjust the height of the mounting base 2 relative to the slider 42, thereby adjusting the height of the nozzle a relative to the carrier plate 1. This ensures that the heights of the multiple nozzles a are consistent, and that the heights of the spray surfaces of the multiple nozzles a are consistent, ensuring printing consistency and improving printing accuracy.

[0094] By using multiple sets of third adjustment structures 33 to adjust the height of different positions of the mounting base 2, the horizontality of the ejection surface of the nozzle a on the mounting base 2 can be adjusted to ensure that the ejection surface of the nozzle a is set horizontally, thereby improving printing accuracy.

[0095] Reference Figure 6-Figure 8 Furthermore, the sliding assembly 4 also includes a connecting plate 44, which is fixed to the top surface of the slider 42. The connecting plate 44 replaces the slider 42 and is connected to the third adjustment structure 33, that is, the first adjusting bolt 331 is threadedly connected to the connecting plate 44, and the second adjusting bolt 332 is pressed against the connecting plate 44.

[0096] With this arrangement, when the first adjusting bolt 331 and the second adjusting bolt 332 are turned to change the height of the mounting base 2, both the first adjusting bolt 331 and the second adjusting bolt 332 apply force to the connecting plate 44. Due to the blocking effect of the connecting plate 44, the slider 42 is not easily slightly deformed due to the force, thereby ensuring the sliding accuracy of the slider 42.

[0097] In this embodiment, after the nozzle a is installed on the supporting plate 1 along with the mounting base 2, the second adjustment structure 32 is first used to adjust the position of the nozzle a in the second direction and the length direction of the arrangement of the nozzle holes of the nozzle a to ensure that the arrangement length directions of the nozzle holes of all the nozzles a are consistent. Then, the position of the nozzle a in the first direction is changed by the first adjustment structure 31, so that the nozzle holes of multiple nozzles a can form an interpolation fit, or the nozzle holes of multiple nozzles a can be evenly spaced in the same direction. Subsequently, the height of the mounting base 2 is adjusted using the third adjustment structure 33 to adjust the height of the nozzle a to ensure that the ejection surface of the nozzle a is horizontal and the ejection surfaces of multiple nozzles a are of the same height. In this embodiment, the adjustment component 3 has a high degree of integration and can achieve precise fine-tuning of the nozzle a in multiple directions to ensure printing accuracy.

[0098] The embodiment of the present application provides a multi-nozzle splicing printing module, wherein multiple nozzles a are respectively mounted on a carrier plate 1 through multiple mounting seats 2, and the positions of the multiple mounting seats 2 and the multiple nozzles a relative to the carrier plate 1 are adjusted by multiple adjustment components 3, so as to achieve the interpolation of the multiple nozzle holes of the multiple nozzles a, and also to achieve the multiple nozzle holes of the multiple nozzles a being evenly spaced in the same direction. Specifically, the first fixing seat 311 is released from the mounting seat 2, and the first push member 312 is used to drive the mounting seat 2 and the nozzles a to move in the first direction, that is, to move in the longitudinal direction of the arrangement of the multiple nozzle holes of the nozzles a, and to adjust the position of each nozzle a to ensure that the multiple nozzle holes of the multiple nozzles a are interpolated, and / or that the multiple nozzle holes of the multiple nozzles a are evenly arranged in the same direction. Subsequently, the mounting seat 2 is fixed to the first fixing seat 311, and the mounting seat 2 can be fixed to the carrier plate 1 to ensure that the position of the nozzle a relative to the carrier plate 1 remains unchanged after the adjustment, so as to facilitate the splicing and installation of the multiple nozzles a. Among them, the setting of the first push member 312 can drive the mounting base 2 and the nozzle a to move more precisely, facilitate the control of the adjustment distance of the nozzle a, and have high adjustment efficiency and adjustment accuracy, meeting the requirements of interpolation printing of multiple nozzles a or lengthening the arrangement length of the nozzle holes.
