Description

Technical Field

[0001] The present application relates to the field of electrofluidic printing auxiliary equipment, and in particular to an electrofluidic nozzle debugging device and an inkjet printing system. 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] Generally, an electrofluidic nozzle includes a power supply unit and an ink storage unit, which are assembled into an electrofluidic nozzle. The ink storage unit includes a mounting unit and a needle body, and the needle body is inserted into the mounting unit. To ensure the consistency of the electrofluidic nozzle, when the needle body and the mounting unit are assembled into the ink storage unit, the distance from the needle tip of the needle body to the mounting unit must be consistent.

[0005] In the related art, before using the electrofluidic printhead, it is necessary to prepare the power supply part and the ink storage part separately, and then assemble the power supply part and the ink storage part to complete the preparation of the electrofluidic printhead. When preparing the ink storage part, it is necessary to inject functional liquid into the needle body and adjust the relative position of the needle body and the mounting part.

[0006] However, both the application of ink to the needle body and the adjustment of the needle body position in the ink storage part need to be done manually. Manual operation results in inconsistent amounts of ink applied to the needle body each time. When adjusting the position of the needle body, it is also difficult to manually adjust the needle body to a specified position relative to the mounting seat, and the adjustment efficiency is low, making it difficult to meet the preparation needs of large quantities of electric fluid nozzles.

DETAILED DESCRIPTION

[0054] 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.

[0055] The embodiment of the present application provides an electrofluid nozzle debugging device and an inkjet printing system. The electrofluid nozzle debugging device automatically applies ink and adjusts the position of the ink storage part in the ink application station and the position adjustment station in turn, thereby improving the preparation accuracy and efficiency of the nozzle before use, and meeting the preparation requirements of a large number of nozzles before use. The present application solves the problem that the manual operation in the related art to prepare the ink storage part has low accuracy and low efficiency, and cannot meet the preparation requirements of a large number of electrofluid nozzles.

[0056] Reference Figure 1 and Figure 2 ,,An electric fluid nozzle debugging device comprises a mounting seat 1, a transposition mechanism 2, an ink supply mechanism 4 and a position adjustment mechanism 5. The mounting seat 1 is used for installing the ink storage part A, and the transposition mechanism 2 drives the mounting seat 1 and the ink storage part A to move to the ink supply mechanism 4 and the position adjustment mechanism 5 in sequence. The ink supply mechanism 4 and the position adjustment mechanism 5 are used to realize automatic ink supply and position adjustment of the ink storage part A, and the preparation work before the nozzle is used is completed accurately and efficiently, which is suitable for the use of large quantities of nozzles.

[0057] The electrofluid nozzle debugging device is used to automatically prepare the ink storage part A before use, with high ink application accuracy, high position adjustment accuracy and high nozzle preparation operation efficiency, which is suitable for the preparation needs of large quantities of nozzles before use.

[0058] Reference Figure 4 , wherein a mounting structure 1a is provided on the mounting seat 1, and the mounting structure 1a is used to realize the installation of the ink storage part A. The ink storage part A includes a mounting part A1 and a needle body A2, and the mounting part A1 is mounted on the mounting seat 1 through the mounting structure 1a, and the top of the needle body A2 is arranged to be open to support the subsequent inking mechanism 4 to inject functional liquid into the needle body A2.

[0059] Reference Figure 4 Specifically, the mounting structure 1a includes a mounting hole, which is opened on the mounting seat 1 and penetrates to the top surface of the mounting seat 1. When the ink storage part A is installed, the mounting part A1 is inserted into the mounting hole to be plugged and matched with the mounting seat 1, and the positioning surface at the top of the mounting part A1 abuts against the mounting seat 1, so as to achieve the height positioning of the mounting part A1.

[0060] With this arrangement, before subsequently adjusting the position of the needle body A2 relative to the mounting portion A1, since the relative position of the mounting portion A1 and the mounting seat 1 is determined, that is, the position of the mounting portion A1 is positioned, when subsequently adjusting the position of the needle body A2, the position adjustment of the needle body A2 is more precise, thereby improving the position adjustment accuracy of the needle body A2.

[0061] It can be understood that the positioning surface of the mounting portion A1 is a side surface or end surface of the mounting portion A1, which is used to locate the height position of the mounting portion A1 by abutting against the mounting seat 1, thereby determining the position of the mounting portion A1.

[0062] In some embodiments, the mounting structure 1a may further include a threaded hole, and the mounting portion A1 is threadedly connected to the mounting seat 1 by the mounting structure 1a. In some embodiments, the mounting structure 1a may further include a clamping structure or a snap-on structure to fix the mounting portion A1 by clamping.

[0063] Reference Figure 1 , wherein the feeding station, the inking station and the position adjustment station are arranged in sequence along a straight line, that is, the driving direction of the position change mechanism 2 is arranged in a straight line, so as to facilitate the rapid and accurate switching of the mounting seat 1 and the ink storage part A on the mounting seat 1 to the designated station. In other embodiments, the feeding station, the inking station and the position adjustment station can also be arranged in sequence along a curve or a broken line.

[0064] In this embodiment, the driving direction of the transposition mechanism 2 is arranged along the first direction. In this embodiment, the first direction is the left-right direction. For ease of understanding, the first direction is the X-axis direction in the figure.

[0065] Reference Figure 1 and Figure 4 In this embodiment, the position-changing mechanism 2 includes a linear motor, a screw mechanism or a belt mechanism. The position-changing mechanism 2 is connected to the mounting seat 1, and can drive the mounting seat 1 to move in the first direction, and send the mounting seat 1 and the ink storage part A to the feeding station, the inking station and the position adjustment station.

[0066] Reference Figure 1-Figure 3 , wherein the inking mechanism 4 is arranged at the inking station, and the needle body A2 is inked by the inking mechanism 4. The inking mechanism 4 includes a quantitative ink outlet component 41. When the needle body A2 moves to the inking station with the mounting seat 1, the needle body A2 is located directly above the quantitative ink outlet component 41, and the functional liquid is injected into the needle body A2 by the quantitative ink outlet component 41.

[0067] With this arrangement, the quantitative ink outlet assembly 41 is used to automatically fill the needle body A2 with ink, the amount of ink filled is more accurately controlled, and the amount of ink filled into the needle body A2 each time is more consistent, thereby improving the accuracy and consistency of inking.

[0068] Reference Figures 1 to 4 In addition, preferably, the electrofluid nozzle debugging device further comprises a correction mechanism 3. The correction mechanism 3 is installed at the driving end of the transposition mechanism 2, and the correction mechanism 3 is drivingly connected to the mounting seat 1. That is, the correction mechanism 3 drives the mounting seat 1 to move along the correction direction, and the transposition mechanism 2 drives the mounting seat 1 to move along the transposition direction.

[0069] In this embodiment, the movement direction of the mounting base 1 driven by the deviation correcting mechanism 3 is the second direction, and the second direction is the front-back direction. For ease of understanding, the second direction is the Y-axis direction in the figure.

[0070] The driving direction of the deflection correction mechanism 3 is set at an angle to the driving direction of the transposition mechanism 2, that is, the first direction is set at an angle to the second direction. In this embodiment, preferably, the driving direction of the deflection correction mechanism 3 is perpendicular to the driving direction of the transposition mechanism 2.

[0071] In this arrangement, the correction mechanism 3 is utilized to drive the mounting seat 1 to move, thereby changing the positions of the mounting seat 1 and the ink storage portion A in the second direction, so as to ensure that the needle body A2 is directly below the quantitative ink outlet component 41, and to ensure that the ink outlet end of the quantitative ink outlet component 41 is aligned with the ink inlet at the top of the needle body A2.

[0072] In some embodiments, the inking mechanism 4 further includes a visual positioning member, which is connected to the quantitative ink outlet assembly 41. The visual positioning member positions the needle body A2 by imaging, and the corresponding control transposition mechanism 2 and the correction mechanism 3 operate to deliver the needle body A2 to the position directly below the ink outlet end of the quantitative ink outlet assembly 41. The visual positioning member includes a camera.

[0073] Reference Figure 2-Figure 5 The quantitative ink dispensing assembly 41 includes an ink supply seat 411, a syringe 412 and an extrusion drive assembly 413. The sleeve 4121 of the syringe 412 is installed on the ink supply seat 411, and the driving end of the extrusion drive assembly 413 is suitable for pressing down the piston rod 4122 of the syringe 412.

[0074] In this configuration, the piston rod 4122 of the syringe 412 is squeezed by the squeezing drive assembly 413 to mobilize the piston rod 4122 to move relative to the sleeve 4121 of the syringe 412, so as to squeeze out the functional liquid in the sleeve 4121, thereby achieving inking of the needle body A2. By controlling the movement distance of the piston rod 4122, the amount of functional liquid injected into the needle body A2 each time can be achieved.

[0075] Reference Figure 2-Figure 5 Specifically, the ink supply seat 411 includes a seat body 4111, a fixed seat 4112 and a pressure plate 4113. The fixed seat 4112 is fixed to the seat body 4111 by bolts. The pressure plate 4113 is arranged on the seat body 4111 to be lifted and slidable, and the pressure plate 4113 is located above the fixed seat 4112, and a clamping space is formed between the pressure plate 4113 and the fixed seat 4112.

[0076] Reference Figure 2-Figure 5 In this embodiment, the sleeve 4121 includes a limiting plate 4121a, which is integrally formed at the top edge of the sleeve 4121 to protrude from the circumferential outer side of the sleeve 4121. The limiting plate 4121a is located between the pressing plate 4113 and the fixing seat 4112, and the limiting plate 4121a is pressed against the fixing seat 4112 by the pressing plate 4113.

[0077] In this arrangement, the limiting plate 4121a is supported by the fixing seat 4112, and the limiting plate 4121a is pressed against the fixing seat 4112 by the pressing plate 4113, so that the limiting plate 4121a is fixed, and the sleeve 4121 can be fixed conveniently and quickly. The pressing plate 4113 presses the sleeve 4121 by its own weight.

[0078] Reference Figure 2-Figure 5 Furthermore, the ink supply seat 411 further includes a stopper 4114, which is fixed to the top surface of the fixed seat 4112, and the stopper 4114 is fixed to the edge of the top surface of the fixed seat 4112. The stopper 4114 is used to support the pressing plate 4113 to prevent the pressing plate 4113 from being directly pressed on the fixed seat 4112, so as to leave a gap between the pressing plate 4113 and the fixed seat 4112 to facilitate separation of the pressing plate 4113 and the fixed seat 4112. In this embodiment, the height of the stopper 4114 is less than the thickness of the limiting plate 4121a.

[0079] In some embodiments, the ink seat 411 also includes a clamping drive component, which is installed on the seat body 4111. The clamping drive component is connected to the pressure plate 4113 to drive the pressure plate 4113 to move up and down, and the sleeve 4121 is fixed by driving the pressure plate 4113 to descend and clamp the limit plate 4121a of the sleeve 4121, and the clamping state of the limit plate 4121a is released by driving the pressure plate 4113 to rise.

[0080] With this arrangement, the syringe 412 is installed in the form of the pressing plate 4113 and the fixing seat 4112, so that the syringe 412 can be quickly installed and removed, thereby improving the efficiency of installing and removing the syringe 412.

[0081] Reference Figure 2-Figure 5 The extrusion drive assembly 413 includes a pressing block 4131 and a linear module 4132. The linear module 4132 drives the pressing block 4131 to press down the piston rod 4122, so that the piston rod 4122 squeezes out the functional fluid in the sleeve 4121. The linear module 4132 includes a screw mechanism or a linear motor.

[0082] In this way, by setting the distance that the pressing block 4131 descends each time, quantitative control of the functional liquid injected into the needle body A2 can be achieved.

[0083] Reference Figure 2-Figure 5Specifically, the pressing block 4131 is arranged on the seat body 4111 to be lifted and slidable, and is located above the fixed seat 4112. In this embodiment, the ink supply seat 411 also includes a plurality of guide rods 4115, which are all installed on the seat body 4111, and the guide rods 4115 are arranged vertically. The pressing block 4131 is sleeved on the guide rods 4115, so that the pressing block 4131 is guided by the guide rods 4115, thereby improving the lifting accuracy of the pressing block 4131. In addition, the pressing plate 4113 is also sleeved on the guide rods 4115, so that the pressing plate 4113 is limited and guided by the guide rods 4115.

[0084] Reference Figure 2-Figure 5 A placement groove 4131a is provided on the side of the pressing block 4131, and an installation groove 4131b is provided on the bottom surface of the pressing block 4131. The installation groove 4131b is connected to the placement groove 4131a, and the end of the installation groove 4131b is open.

[0085] Reference Figure 2-Figure 5 In this embodiment, a pressing piece 4122a is integrally formed on the top of the piston rod 4122, and the pressing piece 4122a extends into the placement groove 4131a, and the piston rod 4122 extends to the bottom of the pressing block 4131 through the installation groove 4131b.

[0086] In this way, the pressing plate 4122a of the piston rod 4122 extends into the placement groove 4131a of the pressing block 4131, and at the same time the limit plate 4121a of the sleeve 4121 is located between the pressing plate 4113 and the fixed seat 4112. Therefore, after the syringe 412 is installed on the ink filling seat 411, the installation of the syringe 412 is more stable, and the sleeve 4121 and the piston rod 4122 are not easy to shake at will, ensuring that when the piston rod 4122 is pushed, the piston rod 4122 only moves relative to the sleeve 4121 to squeeze out the functional liquid, thereby improving the accuracy of inking.

[0087] Reference Figure 2-Figure 5 Furthermore, the extrusion drive assembly 413 also includes a locking bolt 4134, which penetrates from the top of the pressure block 4131 into the placement groove 4131a and is threadedly connected to the pressure block 4131. The locking bolt 4134 is pressed against the pressure plate 4122a of the piston rod 4122 to fix the piston rod 4122 on the pressure block 4131, thereby further improving the movement consistency of the pressure block 4131 and the piston rod 4122, and ensuring that as the pressure block 4131 descends, the piston rod 4122 pushes a specified amount of functional fluid.

[0088] Reference Figure 2-Figure 5Preferably, the extrusion drive assembly 413 further includes a locking plate 4133, which is located in the placement groove 4131a and is used to press the pressing piece 4122a at the top of the piston rod 4122. The locking bolt 4134 is used to press the locking plate 4133 to press the pressing piece 4122a. In this way, the pressing piece 4122a can be prevented from being deformed due to concentrated force at a single point, thereby preventing the piston rod 4122 from being damaged.

[0089] Reference Figure 1 , Figure 2 and Figure 5 , wherein the inking mechanism 4 further includes an inking frame 42 and a lifting drive 43. The inking seat 411 is slidably mounted on the inking frame 42 via a track; the lifting drive 43 is mounted on the inking frame 42, and the lifting drive 43 is drivingly connected to the inking seat 411 to drive the inking seat 411 to move up and down. In this embodiment, the lifting drive 43 includes a linear motor, a cylinder or a screw mechanism.

[0090] Reference Figure 5 When the needle body A2 is located directly below the ink outlet of the syringe 412, the ink holder 411 descends to drive the needle 4123 of the syringe 412 to be inserted into the needle body A2.

[0091] In this way, by lowering the needle body A2 of the syringe 412 to insert the needle 4123 of the syringe 412 into the needle body A2 and then injecting ink into the needle body A2, it is possible to avoid the waste of functional liquid overflowing and affecting the amount of functional liquid actually injected into the needle body A2, thereby improving the ink injection accuracy and ink injection reliability.

[0092] Reference Figure 1 and Figure 6 , wherein the position adjustment mechanism 5 is located at the position adjustment station, and the position adjustment mechanism 5 includes a pulling assembly 51 and an imaging assembly 52. ​​The pulling assembly 51 is used to clamp the needle body A2 and drive the needle body A2 to move relative to the mounting portion A1 of the ink storage portion A. It should be noted that in this embodiment, after the needle body A2 is inserted into the mounting portion A1, the friction between the needle body A2 and the mounting portion A1 is smaller than the friction between the mounting portion A1 and the mounting seat 1 after the mounting portion A1 is inserted into the mounting seat 1. When the pulling assembly 51 drives the needle body A2 to move relative to the mounting portion A1, it will not drive the mounting portion A1 to move relative to the mounting seat 1.

[0093] Reference Figure 6-Figure 8 The imaging component 52 is used to image the needle body A2, and the position of the needle body A2 is determined by the imaging result.

[0094] Reference Figure 6-Figure 8 Specifically, the imaging field of view of the imaging component 52 includes the calibration point a, and the needle tip of the needle body A2 is suitable for moving to the calibration point a.

[0095] With this arrangement, after the ink application is completed, the ink storage unit A moves to the position adjustment station, and the imaging component 52 images the position of the needle body A2. On the one hand, the height position of the needle tip of the needle body A2 is determined, and the pulling component 51 is cooperated to drive the needle body A2 to move relative to the mounting part A1 to adjust the position of the needle body A2 relative to the mounting part A1. The calibration point a in the imaging field of view is used as a reference to ensure that the distance from the needle tip of the needle body A2 to the mounting part A1 is the required distance, and ensure that the relative positions of the needle body A2 and the mounting part A1 are consistent after the batch ink storage unit A is adjusted, thereby improving the consistency of the ink storage unit A and improving the printing quality of the subsequent nozzles. On the other hand, the imaging component 52 images the needle body A2, and the imaging results can be used to determine the state of the functional liquid in the needle body A2, especially in the needle tip of the needle body A2, and determine whether there are bubbles, and remove the ink storage unit A that does not meet the requirements.

[0096] Reference Figure 6-Figure 8 , wherein the pulling assembly 51 includes a clamping jaw 511, a pulling driving member 512 and a pulling frame 513. The pulling driving member 512 is installed on the pulling frame 513, and the clamping jaw 511 is used to clamp the needle body A2. The pulling driving member 512 is connected to the clamping jaw 511 to drive the clamping jaw 511 to move up and down. The pulling driving member 512 includes a screw mechanism or a linear motor. The clamping jaw 511 includes a pneumatic clamping jaw 511.

[0097] With such an arrangement, after the needle body A2 moves to the position adjustment mechanism 5 along with the mounting seat 1, the needle body A2 is located at the clamping position of the clamping jaw 511, the needle body A2 is clamped by the clamping jaw 511, and the pulling drive member 512 is used to drive the clamping jaw 511 to rise and fall, thereby driving the needle body A2 to rise and fall relative to the mounting seat 1, so as to adjust the position of the needle body A2 relative to the mounting seat 1.

[0098] Furthermore, the correction mechanism 3 adjusts the position of the mounting seat 1 so that the needle body A2 is located in the middle of the two clamping ends of the clamping jaws 511 to avoid the needle body A2 being tilted relative to the mounting portion A1 or even damaged when clamping the needle body A2.

[0099] Reference Figure 6-Figure 8 , wherein the imaging component 52 includes an imaging component 521 and a fill light component 522, the imaging component 521 is used to image the needle body A2, and the imaging direction is set at an angle with the driving direction of the transposition mechanism 2, and the fill light component 522 is used to fill light for the needle body A2. The needle body A2 is located between the fill light component 522 and the imaging component 521. In this embodiment, the imaging component 521 includes a camera, and the fill light component 522 includes an LED lamp.

[0100] In this way, the imaging result of the imaging element 521 is clearer through the fill light, ensuring clear imaging of the needle tip position of the needle body A2 and accurate imaging of the state of the functional fluid in the needle body A2. In addition, the arrangement positions of the imaging element 521 and the fill light element 522 do not interfere with the movement path of the mounting base 1.

[0101] Reference Figure 6-Figure 8 Furthermore, the imaging assembly 52 further includes a focus drive 523, which is connected to the imaging element 521 to change the distance between the imaging element 521 and the needle body A2, ensuring that the needle body A2 is in the focal plane of the imaging element 521 to ensure clear imaging. The focus drive 523 includes a linear motor or a screw mechanism.

[0102] The embodiment of the present application provides an electric fluid nozzle debugging device. After the ink storage part A is loaded at the loading station, the position change mechanism 2 drives the ink storage part A to load ink at the loading station and adjust the position of the needle body A2 at the position adjustment station in turn, and the preparation work of the ink storage part A of the nozzle is completed. Therefore, the rhythm of the debugging preparation operation of the ink storage part A is reasonable, and the efficiency of the preparation and debugging of the ink storage part A is high, which is suitable for the preparation needs before the use of a large number of nozzles.

[0103] Among them, at the inking station, the quantitative ink outlet component 41 fills the needle body A2 with functional liquid according to the set functional liquid volume to ensure the consistency of inking of each needle body A2, which is not affected by human experience and operation, and improves the inking accuracy and efficiency.

[0104] After the ink application is completed, the ink storage part A moves to the position adjustment station, and the imaging component 52 images the position of the needle body A2. On the one hand, the height position of the needle tip of the needle body A2 is determined, and the pulling component 51 is cooperated to drive the needle body A2 to move relative to the mounting part A1 to adjust the position of the needle body A2 relative to the mounting part A1. The calibration point a in the imaging field of view is used as a reference to ensure that the distance from the needle tip of the needle body A2 to the mounting part A1 is the required distance, and ensure that the relative positions of the needle body A2 and the mounting part A1 are consistent after the batch ink storage part A is adjusted, thereby improving the consistency of the ink storage part A and improving the printing quality of the subsequent nozzles. On the other hand, the imaging component 52 images the needle body A2, and the imaging results can be used to determine the state of the functional liquid in the needle body A2, especially in the needle tip of the needle body A2, and determine whether there are bubbles, and remove the ink storage part A that does not meet the requirements.

[0105] Therefore, the electrofluid nozzle debugging device is used to automatically prepare the ink storage part A before use, with high ink application accuracy, high position adjustment accuracy and high nozzle preparation operation efficiency, which is suitable for the preparation needs of large quantities of nozzles before use.
