Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inkjet printing processing auxiliary equipment, and particularly relates to an adjusting device of a high-resolution inkjet printing unit. BACKGROUND

[0002] The inkjet printing technology has wide application prospects in many manufacturing fields such as information, energy, medical treatment and national defense, and with the rapid development of technology, the inkjet printing technology is also applied more and more in emerging fields such as OLED, RFID, thin-film solar cell, wearable flexible device, PCB and intelligent skin.

[0003] The inkjet printing unit is a core component of inkjet printing processing, which is seamlessly spliced by a plurality of nozzles. After seamless splicing of the plurality of nozzles, the nozzle holes of the plurality of nozzles are interpolated and matched to improve the printing resolution. In order to adapt to the printing of large-size high-resolution panels, the plurality of nozzle modules need to be seamlessly spliced into a nozzle module group to lengthen the arrangement length of the nozzle holes.

[0004] Generally, the plurality of nozzles need to be accurately assembled into a nozzle module to improve the printing precision and facilitate subsequent assembly of the plurality of nozzle modules into a nozzle module group. Referring to Figure 1 , the nozzle module 6 includes a mounting seat 61 and a plurality of nozzles 63, the plurality of nozzles 63 are arranged in the mounting seat 61 from top to bottom, and the nozzles 63 are connected with the mounting seat 61. The nozzle module includes a plurality of ear plates 62 protruding from the side surface of the mounting seat 61, the ear plate 62 is used for fixing with the external structure, and the side surface of the mounting seat 61 and the side surface of the ear plate 62 can be used as the reference for the installation of the mounting seat 61.

[0005] In the related art, when assembling the nozzle module, the mounting seat is directly installed into the printing device, and then the plurality of nozzles are installed on the mounting seat one by one, and the position of the nozzle is adjusted to ensure that the plurality of nozzles in the nozzle module are seamlessly spliced.

[0006] However, in the printing processing of high-resolution large-size substrates, the plurality of nozzle modules need to be seamlessly spliced into a nozzle module group, and the nozzle module group is used for printing processing of the substrate. If the nozzles are directly assembled into the nozzle module and then the nozzle module is assembled, a large amount of time is required for splicing the nozzles, and a large amount of time is required for detecting the splicing quality of each nozzle module, which is extremely low in efficiency. In addition, due to the space limitation, it is also difficult to detect the position of each nozzle in the nozzle module and to adjust the position of each nozzle when the nozzle module is directly assembled on the printing device.

DETAILED DESCRIPTION

[0042] 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 described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0043] The embodiments of the present application provide an adjustment device for a high-resolution inkjet printing unit. The position of multiple nozzles is conveniently detected and adjusted by using the adjustment device, so that the multiple nozzles are seamlessly spliced into a nozzle module. The assembled nozzle module can be used as a spare part, and the assembled nozzle module is directly assembled into a nozzle module in the subsequent process, so as to improve the assembly efficiency. The present application solves the technical problems of slow assembly efficiency of the nozzle module and difficulty in detecting and adjusting the position of the nozzle in the nozzle module in the related art.

[0044] Reference Figure 2 and Figure 3 An adjustment device for a high-resolution inkjet printing unit, comprising a seat body 1, a positioning structure 2 and a detection assembly 3. The seat body 1 is provided with a through detection groove 1a, the nozzle module 6 is placed at the detection groove 1a, and the nozzle module 6 is positioned by the positioning structure 2. The detection assembly 3 is located below the seat body 1, and is used for detecting the position and height of multiple nozzles 63 of the nozzle module 6, so as to conveniently adjust the position of each nozzle 63 according to the detection result, and realize the precise seamless splicing of the multiple nozzles 63 into the nozzle module 6.

[0045] ReferenceFigure 2 And Figure 3 The surface of the seat body 1 is provided with a through detection groove 1a, the nozzle module 6 is adapted to pass through the detection groove 1a, and the mounting seat 61 of the nozzle module 6 is mounted at the detection groove 1a of the seat body 1. In this embodiment, the width direction of the mounting seat 61 of the nozzle module 6 is arranged along the first direction, the length direction of the mounting seat 61 is arranged along the second direction, and the first direction and the second direction are arranged vertically. The nozzle orifice arrangement length direction of the plurality of nozzles 63 of the nozzle module 6 is arranged along the second direction. Correspondingly, the width direction and the length direction of the detection groove 1a are arranged along the first direction and the second direction respectively. The first direction is the X-axis direction in the figure, and the second direction is the Y-axis direction in the figure.

[0046] Referring to Figures 1-3 Specifically, the lug plate 62 of the nozzle module 6 is arranged on the upper surface of the seat body 1 and connected with the seat body 1 to realize the connection between the nozzle module 6 and the seat body 1.

[0047] Referring to Figure 2 And Figure 3 The positioning structure 2 includes a plurality of positioning blocks 21, and the plurality of positioning blocks 21 are mounted on the plurality of groove walls of the detection groove 1a. The positioning block 21 includes a positioning surface 21a. The side surface of the mounting seat 61 abuts against the positioning surface 21a. In this embodiment, the adjacent two side surfaces of the mounting seat 61 abut against the positioning surfaces 21a of the positioning blocks 21 on the two groove walls of the detection groove 1a to position the mounting seat 61.

[0048] In this way, the position of the mounting seat 61 is positioned by the positioning block 21, so that the relative position between the mounting seat 61 and the seat body 1 is consistent after the mounting seat 61 is mounted on the seat body 1, that is, the relative position between the mounting seat 61 and the seat body 1 of each nozzle module 6 is consistent after each nozzle module 6 is mounted on the seat body 1 when adjusting each nozzle module 6. Therefore, the relative position between the nozzle 63 of each nozzle module 6 and the mounting seat 61 is consistent after the position of the nozzle 63 of the nozzle module 6 is adjusted, which improves the consistency of the plurality of nozzle modules 6. When the plurality of nozzle modules 6 are assembled into a nozzle module group, the plurality of nozzle modules 6 are not easily affected by the difference between the nozzle modules 6, which improves the assembly precision of the nozzle module group. Moreover, the plurality of nozzle modules 6 have good consistency and high interchangeability, which facilitates the overall replacement of the nozzle module 6.

[0049] In addition, after the mounting seat 61 is positioned by the positioning block 21, the width direction of the mounting seat 61 is arranged along the first direction, and the length direction of the mounting seat 61 is arranged along the second direction. When the position of the nozzle 63 is detected, the length direction of the nozzle orifice arrangement of the nozzle 63 is arranged along the second direction, and then the position of the nozzle 63 is fine-adjusted, so that the seamless splicing of the plurality of nozzles 63 is realized, which facilitates the precise adjustment of the position of the nozzle 63.

[0050] Further, by setting the positioning block 21 to contact the mounting seat 61 instead of the groove wall of the detection groove 1a, the positioning surface 21a of the positioning block 21 is easier to ensure the machining precision, that is, the flatness machining precision of the positioning surface 21a is easier to ensure than that of the groove wall of the detection groove 1a. Therefore, after the mounting seat 61 abuts against the positioning surface 21a, the positioning position of the mounting seat 61 is more accurate.

[0051] With reference to Figure 2 and Figure 3 Specifically, a plurality of positioning blocks 21 are arranged on the groove wall in the length direction of the detection groove 1a, and the plurality of positioning blocks 21 are used for abutting against the mounting seat 61. In this way, after the longer side surface of the mounting seat 61 abuts against the plurality of positioning blocks 21, the mounting seat 61 is less likely to be skewed. The position of the mounting seat 61 relative to the seat body 1 is easily ensured.

[0052] Further, the plurality of groove walls of the detection groove 1a are each provided with a receiving groove. The positioning block 21 is installed in the receiving groove, and the positioning surface 21a protrudes from the receiving groove.

[0053] In this way, the receiving groove provides installation space for the positioning block 21, facilitates the determination of the installation position of the positioning block 21, and reduces the space occupied by the positioning block 21 in the detection groove 1a, thereby facilitating the miniaturization design of the seat body 1.

[0054] The mounting seat 61 is preliminarily installed on the seat body 1, and the adjacent two side surfaces of the mounting seat 61 abut against the positioning blocks 21 on the adjacent two groove walls of the detection groove 1a in the first direction and the second direction, respectively. At this time, the positioning of the mounting seat 61 is achieved.

[0055] With reference to Figure 3 and Figure 5 Further, the positioning structure 2 further comprises a positioning sliding assembly 22, and the positioning sliding assembly 22 comprises a positioning sliding rail 221 and a positioning sliding block 222. The positioning sliding rail 221 is installed on the top surface of the seat body 1, and the length direction of the positioning sliding rail 221 is arranged along the first direction. The positioning sliding block 222 is slidingly arranged on the positioning sliding rail 221, and the lug plate 62 of the nozzle module 6 is adapted to abut against the positioning sliding block 222 in the second direction.

[0056] Therefore, when the mounting seat 61 is positioned and installed on the seat body 1, the mounting seat 61 abuts against the positioning block 21 in the first direction, and the lug plate 62 abuts against the positioning sliding block 222 in the second direction, so as to achieve the positioning of the mounting seat 61.

[0057] In the embodiment, the seat body 1 is made of marble, and has a good surface flatness. The positioning guide rail is arranged on the surface of the seat body 1, and the straightness of the positioning guide rail is easy to be ensured. The sliding direction of the positioning sliding block 222 is also easy to be ensured. The positioning sliding block 222 is positioned by abutting against the lug plate 62. The flatness of the side surface of the positioning sliding block 222 and the area of the side surface of the lug plate 62 are smaller, and the machining precision is easy to be ensured, and the flatness precision is higher. Therefore, in the second direction, after the lug plate 62 abuts against the positioning sliding block 222, the positioning precision of the mounting seat 61 is higher.

[0058] In addition, since the positioning sliding block 222 can slide in the first direction, the lug plate 62 can abut against the positioning sliding block 222 by changing the position of the positioning sliding block 222. The application range of the adjusting device is expanded.

[0059] It should be noted that the mounting seat 61 can be positioned by abutting against the positioning blocks 21 on the groove walls of the detection groove 1a through the two adjacent side surfaces respectively; or the mounting seat 61 can be positioned by abutting against the positioning blocks 21 in the first direction, and then the lug plate 62 is used to abut against the positioning sliding block 222 in the second direction to position the mounting seat 61.

[0060] Referring to Figure 3 and Figure 5 Further, the adjusting device of the high-resolution inkjet printing unit further comprises a deviation rectifying assembly 7, and the deviation rectifying assembly 7 comprises an eccentric disc. The eccentric disc is rotationally connected to the surface of the seat body 1, and the circumferential side surface of the eccentric disc abuts against the mounting seat 61. By rotating the eccentric disc, the eccentric disc can push the mounting seat 61. In the embodiment, the eccentric disc pushes the mounting seat 61 in the first direction.

[0061] In this way, the mounting seat 61 is pushed by rotating the eccentric disc to ensure that the mounting seat 61 is tightly attached to the positioning blocks 21, and the positioning precision of the mounting seat 61 is ensured. In addition, the eccentric disc and the positioning blocks 21 clamp the mounting seat 61, and limit the relative movement between the mounting seat 61 and the seat body 1 after positioning, so that the position of the mounting seat 61 is not easy to deviate in the subsequent detection and adjustment process.

[0062] Further, the deviation rectifying assembly 7 further comprises a locking bolt, and an arc-shaped slot is formed in the eccentric disc and penetrates the eccentric disc. The locking bolt is threadedly connected to the seat body 1 through the arc-shaped slot. By tightening the locking bolt, the head of the locking bolt abuts against the eccentric disc, and the movement of the eccentric disc is limited, so that the pushing effect of the eccentric disc on the mounting seat 61 can be maintained.

[0063] In the embodiment, two deviation rectifying assemblies 7 are arranged, and the two deviation rectifying assemblies 7 are arranged in the first direction and are used to act on the opposite side surfaces of the mounting seat 61 respectively.

[0064] Referring to Figure 2 and Figure 4The adjusting device of the high-resolution inkjet printing unit further comprises a plurality of height positioning assemblies 4. The seat body 1 is provided with a plurality of height positioning assemblies 4, and a plurality of height adjusting members are respectively used to adjust the heights of the plurality of lugs 62 of the nozzle module 6, so as to adjust the nozzle module 6 to be horizontal.

[0065] In the embodiment, the lugs 62 are arranged at the corners of the mounting seat 61, and the height positioning assembly 4 is used to adjust the heights of the lugs 62 at the corners of the mounting seat 61, so that the leveling of the mounting seat 61 is realized.

[0066] In this way, after the mounting seat 61 is leveled by the height positioning assembly 4, it is convenient to detect whether the heights of the plurality of nozzles 63 are consistent, and when the positions of the nozzles 63 in the horizontal direction are detected, it is not easy to cause detection errors due to the inclination angle between the bottom surface of the nozzle 63 and the horizontal surface. Therefore, the position detection and adjustment accuracy of the nozzle 63 are improved.

[0067] Referring to Figure 3 and Figure 6 The height positioning assembly 4 comprises a threaded sleeve 41 and a fixing bolt 42. The threaded sleeve 41 is vertically arranged in the seat body 1 and is threadedly connected with the seat body 1, and the top end of the threaded sleeve 41 is used to support and abut against the lug 62. The fixing bolt 42 is arranged in the threaded sleeve 41, the fixing bolt 42 is threadedly connected with the lug 62, and the head of the fixing bolt 42 abuts against the bottom end of the threaded sleeve 41.

[0068] Referring to Figure 3 and Figure 6 By rotating the threaded sleeve 41, the height of the top end surface of the threaded sleeve 41 is adjusted, the heights of the lugs 62 at different corners of the mounting seat 61 are adjusted, and the mounting seat 61 is adjusted to be horizontal. In addition, by tightening the fixing bolt 42, the head of the fixing bolt 42 abuts against the bottom end surface of the threaded sleeve 41, so that the lug 62 is tightly attached to the threaded sleeve 41. By rotating the fixing bolt 42, the mounting accuracy of the contact position between the lug 62 and the plurality of threaded sleeves 41 is further ensured, and it is ensured that the heights of the lugs 62 at the plurality of corners of the mounting seat 61 are adjusted, so that the mounting seat 61 is adjusted to be horizontal.

[0069] Referring to Figure 3 and Figure 6 Further, the height positioning assembly 4 further comprises a locking nut 43. The locking nut 43 is arranged close to the bottom of the threaded sleeve 41, the locking nut 43 is sleeved on the threaded sleeve 41 and is threadedly connected with the threaded sleeve 41. The top end surface of the locking nut 43 abuts against the seat body 1.

[0070] In this way, after the adjustment of the threaded sleeve 41 and the fixing bolt 42, the locking nut 43 is tightened to abut against the seat body 1, at this time, the threaded sleeve 41 is fixed with the seat body 1, the threaded sleeve 41 is not easy to rotate due to external force, and the position of the threaded sleeve 41 relative to the seat body 1 is maintained. In the subsequent detection and adjustment of the position of the nozzle 63, the height of the mounting seat 61 is also not easy to change.

[0071] It should be noted that after the mounting seat 61 is placed on the seat body 1, the multiple ear plates 62 of the mounting seat 61 are arranged on the upper surface of the seat body 1. Due to the flatness of the upper surface of the seat body 1 and the flatness of the bottom surface of the ear plate 62, and due to the certain height deviation of the multiple ear plates 62, the mounting seat 61 is not horizontal, but the inclination of the mounting seat 61 is small, usually in the micron level, which can be corrected to a horizontal state by the combined adjustment of the threaded sleeve 41 and the fixing bolt 42.

[0072] Referring to Figure 3 and Figure 6 In addition, a gap is left between the circumferential outer side surface of the shank of the fixing bolt 42 and the circumferential inner side surface of the threaded sleeve 41 to leave space for the movement of the fixing bolt 42 with the nozzle module 6.

[0073] In this way, the cooperation of the fixing bolt 42 and the threaded sleeve 41 fixes the mounting seat 61 on the seat body 1, before the fixing bolt 42 is tightened, the mounting seat 61 is moved to be positioned, at this time, the fixing bolt 42 can move relative to the threaded sleeve 41 to support the movement and positioning of the mounting seat 61.

[0074] Referring to Figure 4 and Figure 5 In some embodiments, the height positioning assembly 4 includes a positioning plate 44, the positioning plate 44 includes a fixed part 44a and a pressing part 44b, the fixed part 44a is detachably connected to the top surface of the seat body 1, and the pressing part 44b is adapted to be pressed from top to bottom on the ear plate 62.

[0075] Specifically, the fixed part 44a of the positioning plate 44 is connected to the seat body 1 by a bolt, and the fixed position of the positioning plate 44 corresponds to the mounting position of the ear plate 62. By pressing the ear plate 62 with the pressing part 44b of the positioning plate 44, the ear plate 62 is tightly attached to the surface of the seat body 1, thereby achieving the height positioning of the ear plate 62. It should be understood that the seat body 1 is a marble platform, and the flatness of its surface is high in accuracy. By pressing the ear plate 62 against the surface of the seat body 1, the height positioning of the multiple ear plates 62 is achieved, and the mounting seat 61 is adjusted to be horizontal.

[0076] Referring to Figure 7 and Figure 8Further, the adjusting device of the high-resolution inkjet printing unit further comprises a support plate 5, which is detachably installed on the top surface of the base body 1 and spans the detection groove la. The length direction of the support plate 5 is arranged along the first direction, and a plurality of positions for installing the support plate 5 are arranged on the base body 1 in the second direction. The support plate 5 is adapted to support the lug plate 62 of the nozzle module 6.

[0077] In this way, by arranging the support plate 5, one end of the mounting seat 61 is arranged on the base body 1 in the length direction of the mounting seat 61, and the other end of the mounting seat 61 is arranged on the support plate 5. By changing the position of the support plate 5, the mounting seat 61 of various length specifications can be installed, and the nozzle module 6 of various size specifications can be adjusted.

[0078] Referring to Figure 7 and Figure 8 In this embodiment, the support plate 5 is connected to the base body 1 by a plurality of height positioning assemblies 4, and the height positioning assemblies 4 are arranged close to the support plate 5 to ensure that the support plate 5 is horizontal.

[0079] Referring to Figure 7 and Figure 8 Further, a plurality of height positioning assemblies 4 are arranged on the support plate 5. The height positioning assemblies 4 on the support plate 5 are used to adjust the height of the lug plate 62 arranged on the support plate 5, so as to adjust the mounting seat 61 to be horizontal. The specific structure of the height positioning assemblies 4 is the same as that of the height positioning assemblies 4 arranged on the base body 1, and will not be described here.

[0080] The detection assembly 3 comprises a detection seat 31, a detection movement assembly 32, and a detection module 33. The detection seat 31 is located below the base body 1 and is connected to the base body 1 by a plurality of support columns. The detection module 33 is movably arranged in the detection seat 31, and the detection movement assembly 32 is drivingly connected to the detection module 33 to drive the detection module 33 to move in the first direction and the second direction which are perpendicular to each other. By driving the detection module 33 to move, the detection module 33 gradually detects the positions and heights of the plurality of nozzles 63 of the nozzle module 6. And the positions and heights of the plurality of nozzles 63 of the nozzle module 6 are adjusted according to the detection results.

[0081] Referring to Figure 2 and Figure 9 Specifically, the detection movement assembly 32 comprises a first movement module 321 and a second movement module 322. The first movement module 321 is drivingly connected to the detection module 33 to drive the detection module 33 to move in the first direction. The first movement module 321 is installed on the driving end of the second movement module 322, and the second movement module 322 drives the first movement module 321 and the detection module 33 to move synchronously in the second direction.
