Description

Technical Field

[0001] The present application relates to the field of electrofluid printing auxiliary equipment, and in particular to a pre-installation adjustment device for an electrofluid nozzle. Background Art

[0002] As an additive manufacturing technology, inkjet printing technology has the advantages of non-contact, large area, no need for mask, rapid manufacturing, low cost of finished products, and the ability to directly manufacture patterns on flat / curved substrates. It is the main manufacturing technology for printed electronics that will replace the long photolithography / vacuum process (development, etching, exposure and cleaning, etc.), and is widely used in display, sensing, chip, energy, aerospace and other fields.

[0003] Electrofluidic printing technology uses electric field force to pull the droplets out of the nozzle, making the printed dot diameter much smaller than the nozzle diameter, reducing the diameter of the ejected droplets to meet the printing needs of higher pixel density and greatly improving the printing resolution.

[0004] The electrofluid array nozzle is composed of multiple electrofluid nozzles. Figure 1 , is a schematic diagram of an electrofluidic nozzle 6, which includes a needle body 61 and a mounting portion 62. The needle body 61 is inserted into the mounting portion 62, and the mounting portion 62 is locked on the needle body 61 by bolts to achieve the fixation of the needle body 61 and the mounting portion 62. The electrofluidic nozzle 6 is installed by inserting the needle body 61 into the nozzle seat, and the relative position of the positioning surface of the mounting portion 62 and the nozzle seat is determined to determine the relative position of the electrofluidic nozzle and the nozzle seat.

[0005] During electrofluid printing, printing accuracy is affected by printing height. Printing accuracy can be ensured by ensuring that the heights of the ejection points of multiple electrofluid nozzles are consistent, that is, the heights of the tips of multiple needles are consistent.

[0006] In the related art, when a plurality of electrofluid nozzles are mounted on a nozzle seat, the relative positions of the mounting seat and the nozzle seat are changed, and the assembly positions of all the electrofluid nozzles are adjusted to ensure that the heights of the ejection points of all the electrofluid nozzles are consistent.

[0007] However, to make the ejection points of multiple electrofluidic nozzles have the same height, it is necessary to adjust the assembly positions of the electrofluidic nozzles one by one, and the individual adjustment operation is difficult due to the small spacing between the electrofluidic nozzles. In addition, when the distance between the ejection points of different electrofluidic nozzles and the positioning surface is too different, it is still difficult to ensure that the ejection points of all electrofluidic nozzles have the same height by only adjusting the assembly positions of the electrofluidic nozzles, and it is difficult to ensure printing accuracy. Summary of the invention

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The embodiment of the present application provides a pre-installation adjustment device for an electric fluid nozzle, which utilizes an adjustment module to drive the electric fluid nozzle to move so that the tip of the needle is at a calibration point within the field of view of the imaging component, and then moves the installation portion of the electric fluid nozzle to abut against a positioning component to complete the adjustment of the electric fluid nozzle. This can make the distance from the spray point of multiple electric fluid nozzles to the positioning surface consistent, facilitate the assembly process of the array nozzle module, and ensure that the multiple electric fluid nozzles after adjustment can be assembled to the same height at the spray point, thereby ensuring printing accuracy. The present application solves the technical problems in the related art that when multiple electric fluid nozzles are assembled into an array nozzle, it is difficult to adjust the assembly position of the electric fluid nozzles one by one, and because the size differences of the multiple electric fluid nozzles are too large, it is difficult to adjust the spray points of the multiple electric fluid nozzles to a consistent height through assembly, and it is difficult to ensure printing accuracy.

[0044] Reference Figure 1The electrofluid nozzle 6 includes a needle body 61 and a mounting portion 62. The mounting portion 62 is sleeved on the needle body 61 and fixed to the needle body 61 by bolts. The tip of the needle body 61 is the ejection point of the electrofluid nozzle 6. The mounting portion 62 includes a first positioning surface 62a and a second positioning surface 62b. When the electrofluid nozzle 6 is installed, the first positioning surface 62a or the second positioning surface 62b is used to determine the installation position of the electrofluid nozzle 6.

[0045] Reference Figure 1 and Figure 2 , a device for adjusting an electric fluid nozzle before installation, comprising a machine platform 1 and an adjustment module 2, an imaging module 3 and a positioning module 4 arranged on the machine platform 1. Among them, the adjustment module 2 is used to fix the electric fluid nozzle 6, clamp the needle body 61 of the electric fluid nozzle 6 and drive the electric fluid nozzle 6 to move, so that the tip of the needle body 61 is placed at the calibration point 31a within the field of view of the imaging module 3, and then the mounting part 62 is moved relative to the needle body 61, so that the first positioning surface 62a of the mounting part 62 abuts against the positioning component to complete the adjustment of the electric fluid nozzle 6. Since the distance from the calibration point 31a to the positioning component is fixed, the distance from the ejection point of the electric fluid nozzle 6 to the first positioning surface 62a is determined. By adjusting multiple electric fluid nozzles 6, the distance from the ejection point of multiple electric fluid nozzles 6 to the first positioning surface 62a can be made consistent.

[0046] Reference Figure 3 and Figure 4 , wherein the adjustment module 2 includes a fixed seat 21, an adjustment seat 22, a clamping assembly 23 and an adjustment drive 24. The fixed seat 21 is fixed to the machine table 1 by bolts, and the adjustment seat 22 is slidably arranged on the fixed seat 21 along the first direction. The adjustment drive 24 is installed on the fixed seat 21, and the adjustment drive 24 is driven and connected with the adjustment seat 22 to drive the adjustment seat 22 to move in the first direction. In this embodiment, the first direction is the Y-axis direction in the figure. Wherein, the adjustment drive 24 includes a differential head, a linear motor or a screw mechanism.

[0047] Reference Figure 3 and Figure 4 The clamping assembly 23 is installed on the adjustment seat 22 and is used to clamp the fixed electrofluidic nozzle 6. Specifically, the clamping assembly 23 is used to clamp the needle body 61 of the electrofluidic nozzle 6. After the electrofluidic nozzle 6 is clamped, the center line direction of the electrofluidic nozzle 6 is set along the first direction. As the adjustment seat 22 moves in the first direction, the electrofluidic nozzle 6 moves in the first direction.

[0048] Specifically, the clamping assembly 23 includes a first clamping block 231 and a second clamping block 232. The first clamping block 231 is fixed on the adjustment table, and the second clamping block 232 is lifted and lowered above the first clamping block 231. A bolt is inserted between the first clamping block 231 and the second clamping block 232, and the bolt passes through the second clamping block 232 and is threadedly connected to the first clamping block 231. A clamping groove 23a is left between the first clamping block 231 and the second clamping block 232. When clamping the needle body 61, the needle body 61 is inserted into the clamping groove 23a, and the second clamping block 232 is used to approach the first clamping block 231 by tightening the bolt, so as to clamp the needle body 61.

[0049] Reference Figure 5 Furthermore, the first clamping block 231 and the second clamping block 232 are provided with arc grooves 23b on the opposite sides, and the shape of the groove wall of the arc groove 23b is consistent with the shape of the circumferential outer wall of the needle body 61. The first clamping block 231 and the second clamping block 232 are in contact with the needle body 61 through the groove wall of the arc groove 23b.

[0050] In this way, due to the arrangement of the arc groove 23b, when the needle body 61 is clamped, on the one hand, the needle body 61 is not easily displaced, and on the other hand, the arc groove 23b guides the needle body 61, and after the needle body 61 is clamped, the overall length direction is ensured to be arranged along the first direction. Moreover, each time the needle body 61 is clamped, the length direction of the clamped needle body 61 can be ensured to be consistent, and it is not easy for the length direction of the needle body 61 to deviate from the first direction, resulting in an error in the adjustment of the electrofluid nozzle 6.

[0051] In other embodiments, the clamping assembly 23 may further include a robot.

[0052] Reference Figure 2 and Figure 7 , wherein the imaging module 3 and the adjustment module 2 are spaced apart in the first direction. The imaging module 3 includes an imaging member 31, and the imaging direction of the imaging member 31 is arranged along the second direction, and the second direction is arranged at an angle to the first direction. The imaging member 31 is used to image the needle body 61, and the field of view of the imaging member 31 includes a calibration point 31a, and the calibration point 31a is located on the movement path of the needle body 61. In this embodiment, the second direction is the X-axis direction in the figure.

[0053] In this arrangement, as the adjustment seat 22 moves in the first direction, the needle body 61 also moves in the first direction. At this time, the imaging member 31 images the needle body 61, and the position of the tip of the needle body 61 is observed until the tip of the needle body 61 moves to the calibration point 31a within the field of view of the imaging member 31. At this time, the movement of the needle body 61 is completed. Since the size of the needle body 61 is small, the size of its tip is at the micron level. The position of the tip of the needle body 61 is determined by the imaging of the imaging member 31, and the position determination is more accurate. In addition, there is no need to physically contact the tip of the needle body 61, and the tip of the needle body 61 will not be damaged during the adjustment process.

[0054] In this embodiment, the imaging element 31 includes a high-power camera.

[0055] Preferably, the second direction is perpendicular to the first direction, that is, the imaging element 31 images the needle body 61 on the front side of the needle body 61, so as to more accurately determine the position of the tip of the needle body 61. In addition, the position of the calibration point 31a in the field of view of the imaging element 31 in the first direction is easier to determine, so as to facilitate the determination of the distance from the calibration point 31a to the positioning component, and to facilitate the determination of the distance from the ejection point of the electric fluid nozzle 6 to the first positioning surface 62a or the second positioning surface 62b.

[0056] Reference Figure 2 and Figure 8 Further, the imaging module 3 also includes a mounting seat 32 and a focus driving member 33. The imaging member 31 is slidably disposed on the mounting seat 32 along the second direction, the focus driving member 33 is mounted on the mounting seat 32, and the focus driving member 33 is drivingly connected to the imaging member 31 to drive the imaging member 31 to move in the second direction.

[0057] In this arrangement, the position of the imaging member 31 in the second direction is changed by the focus driving member 33 to ensure that the needle body 61 is in the focal plane of the imaging member 31, so as to more accurately determine the position of the tip of the needle body 61 through imaging.

[0058] In this embodiment, the focus driving component 33 includes a micrometer head, a lead screw mechanism or a linear motor.

[0059] Reference Figure 2 and Figure 7 Further, the imaging module 3 further includes a fill light component 34, which is mounted on the machine platform 1, and the fill light component 34 and the imaging component 31 are spaced apart in the second direction, and the adjustment module 2 is located between the imaging component 31 and the fill light component 34. When imaging the needle body 61, the fill light component 34 provides fill light to the needle body 61.

[0060] Specifically, the fill light component 34 includes a light source component 341 and a fill light seat 342 . The fill light seat 342 is fixed to the machine platform 1 . The light source component 341 is fixed on the fill light seat 342 . The irradiation direction of the light source component 341 is set along the second direction.

[0061] Furthermore, the fill light seat 342 is a lifting frame to adapt to the height of the imaging element 31 and to adapt to changing the fill light height.

[0062] With this arrangement, by supplementing light to the needle body 61 , the position of the needle body 61 is clearer during imaging, and the positioning position of the needle body 61 is more accurate.

[0063] The pre-installation adjustment device for the electrofluid nozzle further comprises at least one lifting linear module 5. When there is one lifting linear module 5, the lifting linear module 5 is connected to the imaging component 31 or the fixing seat 21 to adjust the height of the imaging component 31 or the fixing seat 21. When there are two lifting linear modules 5, the two lifting linear modules 5 are connected to the imaging component 31 and the fixing seat 21 respectively, and the heights of the imaging component 31 and the fixing seat 21 can be adjusted.

[0064] In this way, by adjusting the height of the imaging member 31 and / or the fixing seat 21, it is convenient to make the height of the center line of the needle body 61 consistent with the height of the center of the imaging field of view of the imaging member 31, and the calibration point 31a of the imaging field of view of the imaging member 31 can be set to the center position of the imaging field of view of the imaging member 31. By imaging the tip of the needle body 61 at the center position of the imaging field of view, the influence of the imaging distortion of the imaging member 31 on the imaging accuracy is greatly reduced, and the tip of the needle body 61 is conveniently and accurately adjusted to the calibration point 31a.

[0065] Reference Figure 8 In this embodiment, the lifting linear module 5 is equipped with one, and is drivingly connected to the imaging component 31.

[0066] Reference Figure 8 In this embodiment, the imaging positioning module 4 further includes a lifting seat 35, the lifting seat 35 is fixed on the machine platform 1, and the mounting seat 32 is lifted and slidably arranged on the lifting seat 35. The lifting linear module 5 is installed on the lifting seat 35 and is drivingly connected to the mounting seat 32. In this embodiment, the lifting linear module 5 includes a differential head, and in other embodiments, the lifting linear module 5 may also include a screw mechanism or a linear motor.

[0067] Reference Figure 3 and Figure 4 The positioning module 4 includes a positioning member 41 and a positioning seat 42, the positioning seat 42 is fixed on the machine 1, and the positioning member 41 is installed on the positioning seat 42. The positioning member 41 includes a first reference surface 41a, and the first reference surface 41a is spaced apart from the clamping assembly 23 in the first direction. The first reference surface 41a is suitable for the first positioning surface 62a of the power supply fluid nozzle 6 to abut.

[0068] Reference Figure 4 and Figure 7Specifically, when the tip of the needle body 61 moves to the calibration point 31a of the field of view of the imaging element 31, the mounting portion 62 is slid in the first direction relative to the needle body 61, and the first positioning surface 62a of the mounting portion 62 is abutted against the first reference surface 41a of the positioning member 41, and the mounting portion 62 and the needle body 61 are fixed to complete the adjustment of the electrofluid nozzle 6.

[0069] In this arrangement, since the distance between the calibration point 31a and the first reference surface 41a in the first direction is fixed, when the tip of the needle body 61 is at the calibration point 31a, and the first positioning surface 62a of the mounting portion 62 abuts against the first reference surface 41a of the positioning member 41, the distance from the ejection point of the electrofluid nozzle 6 to the installation position can be determined. After adjusting the plurality of electrofluid nozzles 6, the distance from the ejection point of the plurality of electrofluid nozzles 6 to the installation position can be made consistent.

[0070] Reference Figure 3 and Figure 4 , further, the positioning member 41 also includes a second reference surface 41b, and the second reference surface 41b is arranged opposite to the first reference surface 41a in the first direction. In this embodiment, the positioning member 41 includes a positioning block, and a positioning groove is provided on the top surface of the positioning block, and the two opposite groove walls of the positioning groove are respectively the first reference surface 41a and the second reference surface 41b. After the electrofluid nozzle 6 is installed on the adjustment seat 22, the mounting portion 62 is located between the first reference surface 41a and the second reference surface 41b.

[0071] When the electrofluid ejector 6 is installed with the second positioning surface 62b of the mounting portion 62 as a reference, when adjusting the electrofluid ejector 6, after the tip of the needle 61 moves to the position of the calibration point 31a, the mounting portion 62 is moved so that the second positioning surface 62b of the mounting portion 62 abuts against the second reference surface 41b of the positioning member 41. Since the distance between the calibration point 31a and the second reference surface 41b in the first direction is fixed, the distance between the ejection point of the electrofluid ejector 6 and the second positioning surface 62b in the first direction is determined, and the adjustment of the electrofluid ejector 6 is completed.

[0072] With this arrangement, no matter whether the electrofluid nozzle 6 is installed with reference to the first positioning surface 62a or the second positioning surface 62b of the mounting portion 62, the distance between the ejection point and the positioning point of multiple electrofluid nozzles 6 can be adjusted to be consistent through the adjustment device, thereby widening the application range of the adjustment device.

[0073] Reference Figure 6 Further, the positioning module 4 also includes a positioning linear module 43, and the positioning member 41 is slidably disposed on the positioning seat 42 along the first direction. The positioning linear module 43 is installed on the positioning seat 42, and the positioning linear module 43 is drivingly connected to the positioning member 41 to drive the positioning member 41 to move in the first direction.

[0074] In this way, the distance between the first reference plane 41a and the second reference plane 41b and the calibration point 31a in the first direction is changed by changing the position of the positioning member 41 in the first direction. When adjusting the electrofluidic nozzle 6, the distance between the ejection point and the positioning point of the electrofluidic nozzle 6 can be adjusted to a desired size according to the process requirements to meet different processing requirements of the electrofluidic nozzle 6 in the later stage.

[0075] In this embodiment, the positioning linear module 43 includes a micrometer head, a linear motor or a screw mechanism.

[0076] The embodiment of the present application provides a pre-installation adjustment device for an electric fluid nozzle, wherein the electric fluid nozzle 6 to be adjusted is fixed on the adjustment seat 22 by using a clamping assembly 23, and the adjustment platform and the electric fluid nozzle 6 are driven to move synchronously along the first direction by adjusting the driving member 24, so that the tip of the needle body 61 moves to the calibration point 31a within the field of view of the imaging member 31, and finally the mounting portion 62 on the moving needle body 61 is moved so that the first positioning surface 62a of the mounting portion 62 abuts against the first reference surface 41a of the positioning member 41. Since the distance from the calibration point 31a to the first reference surface 41a in the first direction is fixed, the distance from the ejection point of the adjusted electric fluid nozzle 6 to the first positioning surface 62a is determined. By adjusting a plurality of electric fluid nozzles 6, the distance from the ejection point of a plurality of electric fluid nozzles 6 to the first positioning surface 62a can be made consistent.

[0077] Before the electrofluidic nozzle 6 is installed on the nozzle seat to be assembled into an array nozzle module, the electrofluidic nozzle 6 is adjusted to ensure that the distance between the ejection point of each electrofluidic nozzle 6 and the first positioning surface 62a is consistent. Therefore, when multiple electrofluidic nozzles 6 are assembled later, it is easier to ensure that the ejection points of multiple electrofluidic nozzles 6 are at the same height, which reduces the operation of adjusting the assembly position of the electrofluidic nozzle 6 when assembling the electrofluidic nozzle 6, and facilitates the assembly process of the array nozzle module; in addition, there will be no problem of too large a difference in the length size of the electrofluidic nozzle 6. Even if the installation position of the electrofluidic nozzle 6 still needs to be adjusted due to assembly accuracy later, it can be ensured that the adjusted multiple electrofluidic nozzles 6 can be assembled to the same ejection height, thereby ensuring printing accuracy.
