DETAILED DESCRIPTION

[0037] 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 those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0038] The embodiments of the present application provide an adjusting device of an electro-fluidic jet head and an inkjet printing system. The adjusting device of the electro-fluidic jet head automatically drives a needle body to move relative to a mounting portion through a pulling assembly and an imaging assembly, so as to adjust the relative position of the mounting portion and the needle body in an ink storage unit with high precision and high efficiency, improve the precision, consistency and efficiency of the adjustment of the ink storage unit, and adapt to the demand of mass popularization and application of the electro-fluidic jet head. The present application solves the technical problem that in the related art, when the position of the needle body and the mounting portion is adjusted manually, the adjustment precision is low, the consistency is poor, and the efficiency is low, and it is difficult to cope with the demand of mass popularization and application of the electro-fluidic jet head.

[0039] REFERENCE Figure 1The adjusting device of the electro-fluidic jet head comprises a mounting base 1 and a position adjusting mechanism 2. After the mounting part A1 of the ink storage part A is mounted on the mounting base 1, the needle body A2 of the ink storage part A is clamped by the position adjusting mechanism 2 and is driven to move relative to the mounting part A1, so as to adjust the relative position of the needle body A2 and the mounting part A1.

[0040] Specifically, the ink storage part A of the electro-fluidic jet head needs to ensure that the distance between the needle tip of the needle body A2 and the mounting part A1 is consistent. In this way, the state of the functional liquid sprayed by each electro-fluidic jet head is more consistent when the electro-fluidic jet head is used, so as to ensure the printing quality.

[0041] With reference to Figures 1-3 The mounting structure 1a is used for mounting the mounting part A1 of the ink storage part A and determining the position of the mounting part A1 relative to the mounting base 1.

[0042] In this way, after the mounting part A1 is mounted on the mounting base 1, the position of the mounting part A1 is determined, so that the position of the needle body A2 can be adjusted with reference to the position of the mounting part A1, which reduces the adjusting difficulty, improves the adjusting efficiency, and improves the adjusting accuracy.

[0043] With reference to Figures 1-3 Specifically, the mounting structure 1a comprises a reference surface 1a1, and the mounting part A1 comprises a positioning surface A1a. The positioning surface A1a of the mounting part A1 abuts against the reference surface 1a1 to determine the relative position of the mounting part A1 and the mounting base 1. In this embodiment, the reference surface 1a1 is the bottom surface of the mounting base 1, and the positioning surface A1a is a horizontal surface of the mounting part A1.

[0044] In this way, by abutting the positioning surface A1a against the reference surface 1a1, the height of the mounting part A1 is determined, and therefore only the height of the needle body A2 needs to be adjusted so that the height of the needle tip of the needle body A2 is at a specific position, and the adjustment of the position of the needle body A2 relative to the mounting part A1 is completed, which facilitates the position adjustment of the needle body A2 and improves the adjusting efficiency.

[0045] With reference to Figures 1-3 Specifically, the mounting structure 1a further comprises a mounting hole 1a2, and the mounting part A1 comprises a plug A1b. The plug A1b is adapted to be inserted into the mounting hole 1a2, so that the mounting part A1 and the mounting base 1 are in plug-in cooperation, and the positioning surface A1a abuts against the reference surface 1a1.

[0046] With reference to Figures 1-3In the embodiment, the mounting hole 1a2 is formed on the mounting base 1 and penetrates to the top surface of the mounting base 1. When the ink storage portion A is installed, the mounting portion A1 is inserted into the mounting hole 1a2 to be insertedly connected with the mounting base 1, and the positioning surface A1a of the mounting portion A1 abuts against the reference surface 1a1 of the bottom surface of the mounting base 1, so that the height of the mounting portion A1 is positioned.

[0047] In this way, before the position of the needle body A2 is adjusted relative to the mounting portion A1, the relative position of the mounting portion A1 and the mounting base 1 is determined, that is, the position of the mounting portion A1 is positioned, and when the position of the needle body A2 is adjusted, the position of the needle body A2 is adjusted more accurately, and the position adjustment accuracy of the needle body A2 is improved.

[0048] In some embodiments, the installation direction of the ink storage portion A can also be a non-vertical direction, for example, the ink storage portion A is installed horizontally to the mounting base 1, and at this time, the needle body A2 is arranged horizontally, and the center line of the mounting hole 1a2 is also arranged horizontally.

[0049] In some embodiments, the mounting structure 1a can further include a threaded hole, and the mounting portion A1 is threadedly connected with the mounting base 1 by using the mounting structure 1a. In some embodiments, the mounting structure 1a can further include a clamping structure or a clamping structure, so as to fix the mounting portion A1 in the form of clamping.

[0050] Referring to Figure 1 and Figure 4 The position adjustment mechanism 2 includes a pulling assembly 21 and an imaging assembly 22. The pulling assembly 21 is used to clamp the needle body A2 of the ink storage portion A and drive the needle body A2 to move relative to the mounting portion A1 of the ink storage portion A. In the embodiment, the pulling assembly 21 drives the needle body A2 to move in the vertical direction along the length direction of the needle body A2. In other embodiments, the driving direction of the pulling assembly 21 is consistent with the length direction of the needle body A2, that is, the distance between the needle tip of the needle body A2 and the mounting portion A1 can be adjusted.

[0051] Referring to Figures 4-6 The imaging assembly 22 is used to image the needle body A2, and the imaging field of view of the imaging assembly 22 includes the calibration point a. It can be understood that the height of the imaging assembly 22 is determined, and the height of the calibration point a is also determined. In addition, after the mounting portion A1 is installed on the mounting base 1, the height of the mounting portion A1 is also determined, so that by adjusting the height of the calibration point a in the imaging assembly 22, the height difference between the calibration point a and the mounting base 1 is controlled. Then, when the needle tip of the needle body A2 is moved to the calibration point a, the distance between the needle tip and the mounting base 1 can be determined.

[0052] The pulling assembly 21 is adapted to drive the needle tip of the needle body A2 to move to the calibration point a.

[0053] In this way, the imaging assembly 22 images the position of the needle body A2, in a first aspect, judges the height position of the needle tip of the needle body A2, and drives the needle body A2 to move relative to the mounting portion A1 in cooperation with the pulling assembly 21, so as to adjust the position of the needle body A2 relative to the mounting portion A1, and use the calibration point a in the imaging field of view as a reference to ensure that the distance from the needle tip of the needle body A2 to the mounting portion A1 is the required distance, and to ensure that the relative positions of the needle body A2 and the mounting portion A1 are consistent after the ink storage portion A is adjusted, thereby improving the consistency of the ink storage portion A and improving the printing quality of the subsequent inkjet head. In a second aspect, the imaging assembly 22 images the needle body A2, and uses the imaging result to judge the functional liquid state in the needle body A2, especially the needle tip of the needle body A2, to determine whether there is a bubble, and to remove the ink storage portion A that does not meet the requirements.

[0054] Referring to Figure 1 and Figure 4 Specifically, the pulling assembly 21 includes a clamping jaw 211, a pulling driving element 212, and a pulling frame 213. The pulling driving element 212 is installed on the pulling frame 213, the clamping jaw 211 is used to clamp the needle body A2, and the pulling driving element 212 is drivingly connected with the clamping jaw 211 to drive the clamping jaw 211 to move along the length direction of the needle body A2. In this embodiment, the pulling driving element 212 drives the clamping jaw 211 to move in the vertical direction. The pulling driving element 212 includes a screw mechanism or a linear motor. The clamping jaw 211 includes a pneumatic clamping jaw.

[0055] In this way, after the needle body A2 moves to the position adjusting mechanism 2 with the mounting seat 1, the needle body A2 is located at the clamping position of the clamping jaw 211, the clamping jaw 211 clamps the needle body A2, and the pulling driving element 212 drives the clamping jaw 211 to ascend and descend to drive the needle body A2 to ascend and descend relative to the mounting seat 1, so as to adjust the position of the needle body A2 relative to the mounting seat 1.

[0056] The pulling assembly 21 drives the needle body A2 to move along the length direction of the needle body A2. In some embodiments, when the ink storage portion A is horizontally placed, the pulling assembly 21 drives the needle body A2 to move in the horizontal direction.

[0057] Further, the clamping end of the clamping jaw 211 is flexibly arranged. In this embodiment, the clamping jaw 211 is made of soft plastic. In other embodiments, a buffer layer is attached to the clamping surface of the clamping jaw 211, and the buffer layer includes rubber or silicone.

[0058] 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 21 drives the needle body A2 to move relative to the mounting portion A1, the mounting portion A1 will not move relative to the mounting seat 1.

[0059] Referring to Figure 1And Figure 5 Wherein, the imaging assembly 22 comprises an imaging piece 221 and a light supplement piece 222, the imaging piece 221 is used for imaging the needle body A2, and the light supplement piece 222 is used for supplementing light for the needle body A2. The needle body A2 is located between the light supplement piece 222 and the imaging piece 221. In the embodiment, the imaging piece 221 comprises a camera, and the light supplement piece 222 comprises an LED lamp.

[0060] In this way, the imaging result of the imaging piece 221 is clearer through light supplement, clear imaging of the position of the needle tip of the needle body A2 is ensured, and accurate imaging of the state of the functional liquid in the needle body A2 can be realized.

[0061] Referring to Figure 4 And Figure 5 Further, the imaging assembly 22 further comprises a focusing piece 223, the focusing piece 223 is drivingly connected with the imaging piece 221, so as to change the distance between the imaging piece 221 and the needle body A2, ensure that the needle body A2 is in the focal plane of the imaging piece 221, and ensure clear imaging. Wherein, the focusing piece 223 comprises a linear motor or a lead screw mechanism.

[0062] In the embodiment, the needle body A2 is vertically arranged, and the imaging direction of the imaging assembly 22 is horizontally arranged.

[0063] Referring to Figures 1-3 Wherein, the adjusting device of the electrofluidic nozzle further comprises a movement mechanism 3, the movement mechanism 3 is used for changing the relative position between the position adjusting mechanism 2 and the mounting seat 1, so as to realize work station switching. The movement mechanism 3 comprises a transposition driving piece 31, the transposition driving piece 31 drives the mounting seat 1 to move in the transposition direction, so as to drive the ink storage part A on the mounting seat 1 to the position adjusting mechanism 2, and make the needle body A2 be placed in the clamping position of the pulling assembly 21. In the embodiment, the transposition driving piece 31 comprises a lead screw mechanism or a linear motor.

[0064] Referring to Figures 1-3 In the embodiment, the ink storage part A on the mounting seat 1 is driven by the transposition driving piece 31, and the movement direction of the ink storage part A is towards the entrance of the clamping end of the pulling assembly 21. With the movement of the transposition driving piece 31, the needle body A2 extends into the clamping end of the pulling assembly 21.

[0065] In this way, with the movement of the mounting seat 1 driven by the transposition driving piece 31, the needle body A2 moves to the clamping end of the pulling assembly 21, so as to facilitate quick clamping of the needle body A2.

[0066] The relative position between the mounting base 1 and the position adjusting mechanism 2 is switched by arranging the transposition driving member 31, so as to arrange two stations. The position where the mounting base 1 is away from the position adjusting mechanism 2 is the feeding station, and the position where the mounting base 1 is located at the position adjusting mechanism 2 is the adjusting station. Therefore, the feeding of the ink storage part A at the feeding station is convenient, and the position adjustment of the needle body A2 at the adjusting station is convenient. The feeding mode of the ink storage part A is more flexible, and the ink storage part A is not easy to interfere with the position adjusting mechanism 2 during feeding. In addition, through the arrangement of the station, the subsequent arrangement of the mechanism for automatically feeding the ink storage part A is also convenient, so as to further improve the adjustment efficiency.

[0067] In the embodiment, the driving direction of the transposition driving member 31 is perpendicular to the imaging direction of the imaging assembly 22, so as to avoid the interference of the imaging assembly 22 to the movement of the mounting base 1.

[0068] Further, the movement mechanism 3 further comprises a deviation rectifying driving member 32, the deviation rectifying driving member 32 is drivingly connected with at least one of the position adjusting mechanism 2 and the mounting base 1, so as to drive at least one of the position adjusting mechanism 2 and the mounting base 1 to move along the deviation rectifying direction, and the driving direction of the deviation rectifying driving member 32 is arranged at an angle with the driving direction of the transposition driving member 31. In the embodiment, the deviation rectifying driving member 32 comprises a linear motor or a screw mechanism.

[0069] In this way, by arranging the deviation rectifying driving member 32, the relative position between the needle body A2 and the pulling assembly 21 along the deviation rectifying direction is adjusted, so as to ensure that the needle body A2 is located at the middle part of the clamping end of the pulling assembly 21, so as to avoid that the needle body A2 is inclined or even damaged relative to the mounting part A1 during clamping the needle body A2.

[0070] In the embodiment, the driving direction of the deviation rectifying driving member 32 is perpendicular to the driving direction of the transposition driving member 31.

[0071] Referring to Figures 1-3 In the embodiment, the deviation rectifying driving member 32 is mounted at the driving end of the transposition driving member 31, and the deviation rectifying driving member 32 is drivingly connected with the mounting base 1. Therefore, the deviation rectifying driving member 32 drives the mounting base 1 to move along the deviation rectifying direction, and the transposition driving member 31 drives the mounting base 1 to move along the transposition direction.

[0072] The adjustment device of the electro-fluid ejection head provided by the embodiment of the application is arranged to provide the mounting structure 1a of the ink storage part A, and to determine the position of the mounting part A1 of the ink storage part A, so as to conveniently adjust the position of the needle body A2 according to the position of the mounting part A1.

[0073] Due to the arrangement of the position adjusting mechanism 2, the imaging assembly 22 images the position of the needle body A2, in the first aspect, judges the height position of the needle tip of the needle body A2, and drives the needle body A2 to move relative to the mounting portion A1 in cooperation with the pulling assembly 21, so as to adjust the position of the needle body A2 relative to the mounting portion A1, and use the calibration point a in the imaging field of view as a reference to ensure that the distance from the needle tip of the needle body A2 to the mounting portion A1 is the required distance, and ensure that the relative position of the needle body A2 and the mounting portion A1 is consistent after the bulk ink storage portion A is adjusted, thereby improving the consistency of the ink storage portion A and improving the printing quality of the subsequent inkjet head. In the second aspect, the imaging assembly 22 images the needle body A2, and uses the imaging result to judge the functional liquid state in the needle body A2, especially the needle tip of the needle body A2, to determine whether there is a bubble, and to remove the ink storage portion A that does not meet the requirements.

[0074] Therefore, the adjustment device of the electro-fluidic inkjet head is used to automatically adjust the position of the ink storage portion A, has high adjustment accuracy, better consistency for each adjustment, and high adjustment efficiency, and is suitable for the demand of large-scale popularization and application of the electro-fluidic inkjet head.

[0076] Another embodiment of the present application provides an inkjet printing system. Since the inkjet printing system comprises the adjustment device of the electro-fluidic inkjet head as described above, the inkjet printing system has the same beneficial effects as the adjustment device of the electro-fluidic inkjet head, which will not be described herein.
