However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] In the description of the application, it should be understood that, if there are these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0031] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0032] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0033] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0034] It should be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used herein only mean for the purpose of illustration and are not meant to be limiting.

[0035] For the convenience of description, three mutually perpendicular directions are respectively referred to as a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction can be understood as the extension directions of three coordinate axes in a spatial orthogonal coordinate system, for example, the first direction can be the X-axis direction, for example, the second direction can be the Y-axis direction, and for example, the first direction can be the Z-axis direction. That is, the first direction and the second direction are both horizontal directions, for example, the first direction can be the horizontal direction in the transverse direction, and the second direction can be the horizontal direction in the longitudinal direction. The third direction is a vertical direction. Of course, the first direction, the second direction, and the third direction can also not be completely perpendicular to each other, i.e., in a substantially perpendicular relationship.

[0036] Referring to Figure 5 , Figure 6 and Figure 7 , an adjusting device 20 provided in an embodiment of the present application is used in conjunction with an inkjet printer. The inkjet printer includes an inkjet mechanism 10, and the inkjet mechanism 10 includes a nozzle assembly 200. The nozzle assembly 200 is provided with a plurality of ink ejection holes 211, and ink is ejected from the ink ejection holes 211 to print. The number of the nozzle assemblies 200 is multiple, and therefore the number of the ink ejection holes 211 is multiple. The shape of the ink ejection holes 211 can be rectangular. Each ink ejection hole 211 extends along a first direction, and all the ink ejection holes 211 can be arranged to form a plurality of rows of ink ejection holes by being arranged at intervals along the first direction, and the plurality of rows of ink ejection holes are arranged at intervals along a second direction. For the convenience of description, for any two adjacent rows of ink ejection holes arranged at intervals along the second direction, the two adjacent rows of ink ejection holes are respectively referred to as a first row of ink ejection holes and a second row of ink ejection holes. The ink ejection holes 211 in the first row of ink ejection holes are referred to as first ink ejection holes 211a, i.e., the first row of ink ejection holes includes a plurality of first ink ejection holes 211a arranged at intervals along the first direction. The ink ejection holes 211 in the second row of ink ejection holes are referred to as second ink ejection holes 211b, i.e., the second row of ink ejection holes includes a plurality of second ink ejection holes 211b arranged at intervals along the first direction.

[0037] Referring to Figure 5 , Figure 6 and Figure 7In the printing process, in order to ensure the printing quality, two conditions need to be met. The first condition is that the edges of each nozzle 211 in the same row of nozzles 211 extending in the first direction are located on the same straight line, that is, the edges of each nozzle 211 in the same row of nozzles 211 extending in the first direction are aligned in the second direction, that is, the edges of the nozzles 211 arranged in the first direction extending in the first direction are located on the same straight line. The second condition is that for any adjacent first row of nozzles and second row of nozzles, the first nozzle 211a has a projection 2111 in the second direction, and the two ends of the projection 2111 are just connected with the ends of the adjacent two second nozzles 211b, that is, the gap between the ends of the first nozzle 211a and the second nozzle 211b in the first direction is zero, that is, the edges of the adjacent nozzles 211 extending in the second direction are located on the same straight line in the second direction. In this way, in the printing process, it can be avoided that a printing blank is left due to too large gap.

[0038] Referring to Figure 5 , Figure 8 and Figure 9 In some embodiments, the inkjet mechanism 10 further comprises a substrate 100, and the substrate 100 is provided with a plurality of positioning cavities 110. The number of the inkjet head assemblies 200 is equal to the number of the positioning cavities 110, and each inkjet head assembly 200 is located in a corresponding positioning cavity 110. When the inkjet head assembly 200 is located in the positioning cavity 110, the positioning cavity 110 can well position the inkjet head assembly 200, so as to ensure that the length direction of the inkjet head assembly 200 extends in the first direction, and the width direction of the inkjet head assembly 200 extends in the second direction.

[0039] Referring to Figure 5 , Figure 8 and Figure 9 In some embodiments, the inkjet head assembly 200 comprises an inkjet head 210, a mounting seat 220, a first fine adjustment unit 230 and a second fine adjustment unit 240. The mounting seat 220 is matched with the positioning cavity 110. The mounting seat 220 is recessed to form a mounting groove 221, and the inkjet head 210 is arranged in the mounting groove 221. The mounting groove 221 can limit the inkjet head 210 in the first direction and the second direction to a certain extent.

[0040] Referring to Figure 5 , Figure 8 and Figure 9The first fine adjustment unit 230 includes a first elastic member 231 and a first abutting member. The first elastic member 231 and the first abutting member are oppositely arranged on opposite sides of the nozzle 210 along the second direction. The first elastic member 231 is arranged on the mounting seat 220 and can extend into the mounting groove 221, so that the first elastic member 231 exerts an abutting force on the nozzle 210 along the second direction. The first abutting member is arranged in a first through hole 232 of the mounting seat 220, and the first through hole 232 is communicated with the mounting groove 221. The first abutting member can be a bolt or the like, and is threadedly connected with the mounting seat 220 and extends into the mounting groove 221 and abuts against the nozzle 210 along the second direction. Since the first elastic member 231 and the first abutting member are oppositely arranged on opposite sides of the nozzle 210 along the second direction, the directions of the abutting forces exerted by the first elastic member 231 and the first abutting member on the nozzle 210 are opposite. By adjusting the first abutting member to change the length of the first abutting member extending into the mounting groove 221, the deformation amount of the first elastic member 231 can be changed, so that the nozzle 210 slides in the mounting groove 221 along the second direction, thereby changing the position of the nozzle 210 relative to the mounting seat 220 along the second direction, and finally achieving fine adjustment of the position of the nozzle 210 relative to the mounting seat 220 along the second direction. For example, when the length of the first abutting member extending into the mounting groove 221 increases, the first elastic member 231 stores energy and the length of the first elastic member 231 extending into the mounting groove 221 decreases, so that the nozzle 210 moves along the second direction and approaches the first elastic member 231; conversely, when the length of the first abutting member extending into the mounting groove 221 decreases, the first elastic member 231 releases energy and the length of the first elastic member 231 extending into the mounting groove 221 increases, so that the nozzle 210 moves along the second direction and moves away from the first elastic member 231. The number of the first fine adjustment unit 230 can be two, and the first fine adjustment unit 230 is spaced apart from each other along the first direction, so that the two first fine adjustment units 230 are arranged close to opposite ends of the mounting seat 220 along the first direction, so that the force on the nozzle 210 is more balanced, thereby improving the adjustment accuracy of the position of the nozzle 210 relative to the mounting seat 220 along the second direction.

[0041] Referring to Figure 5 , Figure 8 and Figure 9The second fine adjustment unit 240 includes a second elastic member 241 and a second abutting member. The second elastic member 241 and the second abutting member are oppositely arranged on opposite sides of the nozzle 210 along the first direction. The second elastic member 241 is arranged on the mounting seat 220 and can extend into the mounting groove 221, so that the second elastic member 241 exerts an abutting force on the nozzle 210 along the first direction. The second abutting member is arranged in a second through hole 242 of the mounting seat 220, and the second through hole 242 is communicated with the mounting groove 221. The second abutting member can be a bolt or the like, and is threadedly connected with the mounting seat 220 and extends into the mounting groove 221 and abuts against the nozzle 210 along the first direction. Since the second elastic member 241 and the second abutting member are oppositely arranged on opposite sides of the nozzle 210 along the first direction, the abutting forces exerted by the second elastic member 241 and the second abutting member on the nozzle 210 are in opposite directions. By adjusting the second abutting member to change the length of the second abutting member extending into the mounting groove 221, the deformation amount of the second elastic member 241 can be changed, so that the nozzle 210 slides in the mounting groove 221 along the first direction, thereby changing the position of the nozzle 210 relative to the mounting seat 220 along the first direction, and finally achieving fine adjustment of the position of the nozzle 210 relative to the mounting seat 220 along the first direction. For example, when the length of the second abutting member extending into the mounting groove 221 increases, the second elastic member 241 stores energy and the length of the second elastic member 241 extending into the mounting groove 221 decreases, so that the nozzle 210 moves along the first direction and approaches the second elastic member 241; conversely, when the length of the second abutting member extending into the mounting groove 221 decreases, the second elastic member 241 releases energy and the length of the second elastic member 241 extending into the mounting groove 221 increases, so that the nozzle 210 moves along the first direction and moves away from the second elastic member 241. The number of the second fine adjustment unit 240 can be one, so that the structure of the nozzle assembly 200 can be simplified.

[0042] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the adjusting device 20 comprises a base 300 and an adjusting mechanism 400, the base 300 has a first station 3311 for carrying the nozzle assembly 200 and a second station 3312 for carrying the ink ejection mechanism 10, it can be understood that the nozzle assembly 200 at the first station 3311 can be transferred to the second station 3312, so that each nozzle assembly 200 is assembled to form the ink ejection mechanism 10 at the second station 3312. For example, the base 300 can comprise a base platform 310, a connecting piece 320 and a carrier 330, the connecting piece 320 is connected between the base platform 310 and the carrier 330, the connecting piece 320 can extend a certain length along the third direction, that is, one end of the connecting piece 320 is connected with the base platform 310, and the other end of the connecting piece 320 is connected with the carrier 330, the number of the connecting piece 320 can be two, and the two connecting pieces 320 are respectively connected with two ends of the carrier 330 in the first direction. Since the connecting piece 320 has a certain length, the carrier 330 can be spaced apart from the base platform 310 along the third direction, so that the carrier 330 has a certain spacing space with the base platform 310, and the adjusting mechanism 400 can be arranged on the base platform 310 and located in the spacing space. The adjusting mechanism 400 comprises a first sliding piece 410, a second sliding piece 420 and a clamping piece 430, the first sliding piece 410 is movably connected with the base platform 310 of the base 300 along the first direction, the second sliding piece 420 is movably connected with the first sliding piece 410 along the second direction, and the clamping piece 430 is arranged on the second sliding piece 420, so that the clamping piece 430 can slide relative to the base platform 310 in the first direction and the second direction, and the clamping piece 430 has two degrees of freedom.

[0043] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4The carrier 330 has a carrying surface 331 and a back surface 332, both of which are oppositely arranged in the thickness direction of the carrier 330 and face opposite directions, the carrying surface 331 is arranged to face away from the base 310, and the back surface 332 is arranged to face the base 310. The first station 3311 and the second station 3312 are both located on the carrying surface 331, so that the nozzle assembly 200 and the ink ejection mechanism 10 are both located on the carrying surface 331. Obviously, the adjusting mechanism 400 is located on the side where the back surface 332 is located, and the nozzle assembly 200 and the ink ejection mechanism 10 are located on the side where the carrying surface 331 is located. The nozzle assembly 200 and the ink ejection mechanism 10 are located on opposite sides of the carrier 330 with the adjusting mechanism 400, in other words, the nozzle assembly 200 and the ink ejection mechanism 10 are located on the upper side of the carrier 330, and the adjusting mechanism 400 is located on the lower side of the carrier 330. Obviously, the camera 430 is also located on the lower side of the carrier 330. In this way, the special structure of the base 300 can be fully utilized to reasonably arrange the position of the adjusting mechanism 400.

[0044] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, the first station 3311 of the carrier 330 is provided with a first through hole 333, which penetrates the entire carrier 330 in the thickness direction, so that the first through hole 333 penetrates the carrying surface 331 and the back surface 332 at the same time. When the nozzle assembly 200 is located at the first station 3311, the first through hole 333 is in communication with the nozzle hole 211, and the projection 2111 of the nozzle hole 211 located at the first station 3311 in the third direction falls within the first through hole 333. In this way, the camera 430 can take a picture of the nozzle hole 211 located at the first station 3311 through the first through hole 333 to realize image acquisition.

[0045] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, the second station 3312 of the carrier 330 is provided with a second through hole 334, which penetrates the entire carrier 330 in the thickness direction, so that the second through hole 334 penetrates the carrying surface 331 and the back surface 332 at the same time. When the ink ejection mechanism 10 is located at the second station 3312, the first through hole 333 is in communication with the nozzle hole 211 on different nozzle assemblies 200, and the projection 2111 of the different nozzle holes 211 located at the second station 3312 in the third direction falls within the second through hole 334. In this way, the camera 430 can take a picture of the nozzle hole 211 located at the second station 3312 through the second through hole 334 to realize image acquisition.

[0046] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the adjusting device 20 further comprises a plurality of first positioning members 510 located at the edge of the first station 3311, the first positioning members 510 are connected with the carrier 330, and the first positioning members 510 can be pins or the like, so that the first positioning members 510 can protrude a certain height along the third direction to the carrying surface 331, and when the nozzle assembly 200 is located at the first station 3311, the first positioning members 510 can abut against the edge of the nozzle assembly 200. Among all the first positioning members 510, part of the first positioning members 510 are arranged at intervals along the first direction and abut against the nozzle assembly 200 along the second direction, and the other part of the first positioning members 510 are arranged at intervals along the second direction and abut against the nozzle assembly 200 along the first direction. Therefore, when the nozzle assembly 200 is located at the first station 3311, all the first positioning members 510 can abut against the mounting base 220 of the nozzle assembly 200 along the first direction and the second direction respectively, so as to realize the positioning of the nozzle assembly 200 in the first direction and the second direction by the first positioning members 510, thereby improving the positioning accuracy of the nozzle assembly 200 on the carrier 330. After the positioning of the nozzle assembly 200 is completed, the mounting base 220 of the nozzle assembly 200 can be detachably fixed on the carrier 330 in a bolted manner.

[0047] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the adjusting device 20 further comprises a plurality of second positioning members 520 located at the edge of the second station 3312, the second positioning members 520 are connected with the carrier 330, and the second positioning members 520 can be pins or the like, so that the second positioning members 520 can protrude a certain height along the third direction to the carrying surface 331, and when the inkjet mechanism 10 is located at the second station 3312, the second positioning members 520 can abut against the edge of the substrate 100 of the inkjet mechanism 10. Among all the second positioning members 520, part of the second positioning members 520 are arranged at intervals along the first direction and abut against the substrate 100 along the second direction, and the other part of the second positioning members 520 are arranged at intervals along the second direction and abut against the substrate 100 along the first direction. Therefore, when the inkjet mechanism 10 is located at the second station 3312, all the second positioning members 520 can abut against the substrate 100 of the inkjet mechanism 10 along the first direction and the second direction respectively, so as to realize the positioning of the inkjet mechanism 10 in the first direction and the second direction by the second positioning members 520, thereby improving the positioning accuracy of the inkjet mechanism 10 on the carrier 330. After the positioning of the inkjet mechanism 10 is completed, the substrate 100 of the inkjet mechanism 10 can be detachably fixed on the carrier 330 in a bolted manner.

[0048] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the adjusting device 20 further comprises a third positioning member 530 located at the second working position 3312, the third positioning member 530 is connected with the carrier 330, and the third positioning member 530 can be a pin or the like, so that the third positioning member 530 can protrude a certain height along a third direction to the carrier surface 331, when the inkjet mechanism 10 is located at the second working position 3312, the third positioning member 530 can be arranged in the substrate 100 of the inkjet mechanism 10, so as to further improve the positioning accuracy of the inkjet mechanism 10. Of course, the number of third positioning members 530 can be multiple, for example, the number of third positioning members 530 can be two, two third positioning members 530 can be arranged along the extension direction of the diagonal line of the substrate 100, that is, two third positioning members 530 are arranged along a direction which forms a certain angle with the first direction and the second direction, so as to further improve the positioning accuracy of the inkjet mechanism 10.

[0049] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the adjusting mechanism 400 further comprises a first screw rod 441 and a first hand wheel 442. The first screw rod 441 is rotationally connected with the base 300, and extends along a first direction, so that the central axis of the first screw rod 441 extends along the first direction, so that the first screw rod 441 can rotate relative to the base 300 about the central axis of the first screw rod 441, i.e. the first screw rod 441 can rotate about an axis extending along the first direction. Of course, during the rotation of the first screw rod 441, the first screw rod 441 cannot slide along the first direction. The base 310 can be provided with a sliding rail, and the first sliding member 410 can be provided with a sliding groove, and the sliding rail and the sliding groove can be slidably connected, so that the first sliding member 410 and the base 310 are movably connected. The first screw rod 441 is arranged on the first sliding member 410, so that the first sliding member 410 and the first screw rod 441 are threadedly connected. The first hand wheel 442 is arranged at the end of the first screw rod 441, and when the first hand wheel 442 is rotated, the first screw rod 441 can be driven to rotate, so that the first screw rod 441 drives the first sliding member 410 to reciprocally slide relative to the base 310 along the first direction, i.e. the rotation of the first screw rod 441 can be converted into the sliding motion of the first sliding member 410. It can be understood that when the first screw rod 441 stops rotating, the first sliding member 410 can be stably and reliably stopped at a specified position by the self-locking ability of the thread, so as to avoid the first sliding member 410 from continuously sliding relative to the base 310 along the first direction under the impact of external force. In other embodiments, the first hand wheel 442 can be replaced by a motor, and the first screw rod 441 can be replaced by a linear module.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the adjusting mechanism 400 further comprises two first stop members 443. The two first stop members 443 are arranged on the base 310 of the base 300 along the first direction, and the first sliding member 410 is located between the two first stop members 443 along the first direction. During the reciprocating sliding of the first sliding member 410 along the first direction, when the first sliding member 410 abuts against the first stop member 443, the first sliding member 410 can be prevented from continuously sliding along the first direction, and at this time, the first sliding member 410 moves to the limit position, so as to limit the sliding stroke of the first sliding member 410 along the first direction.

[0051] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the adjusting mechanism 400 further comprises a second screw rod 451 and a second hand wheel 452. The second screw rod 451 is rotationally connected with the first sliding member 410, and extends along a second direction. Therefore, the central axis of the second screw rod 451 extends along the second direction, so that the second screw rod 451 can rotate about its central axis relative to the base 300, i.e., the second screw rod 451 can rotate about an axis extending along the second direction. Of course, during the rotation of the second screw rod 451, the second screw rod 451 cannot slide along the second direction. The first sliding member 410 can be provided with a sliding rail, and the second sliding member 420 can be provided with a sliding groove. Through the sliding cooperation of the sliding rail and the sliding groove, the moving connection relationship between the second sliding member 420 and the first sliding member 410 can be achieved. The second screw rod 451 is arranged on the second sliding member 420, so that the second sliding member 420 is threadedly connected with the second screw rod 451. The second hand wheel 452 is arranged at the end of the second screw rod 451. When the second hand wheel 452 is rotated, the second screw rod 451 can be driven to rotate, so that the second screw rod 451 drives the second sliding member 420 to reciprocate along the second direction relative to the first sliding member 410, i.e., the rotation movement of the second screw rod 451 can be converted into the sliding movement of the second sliding member 420. It can be understood that when the second screw rod 451 stops rotating, the second sliding member 420 is stably and reliably stopped at the specified position through the self-locking ability of the thread, so as to avoid the second sliding member 420 from continuously sliding along the second direction relative to the first sliding member 410 under the impact of external force. In other embodiments, the second hand wheel 452 can be replaced by a motor, and the second screw rod 451 can be replaced by a linear module.

[0052] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure , the adjusting mechanism 400 further comprises two second stop members 453. The two second stop members 453 are arranged on the first sliding member 410 along the second direction and are spaced apart. In the second direction, the second sliding member 420 is located between the two second stop members 453. During the reciprocating sliding of the second sliding member 420 along the second direction, when the second sliding member 420 abuts against the second stop member 453, the second sliding member 420 can be prevented from continuously sliding along the second direction. At this time, the second sliding member 420 moves to the limit position, so as to limit the sliding stroke of the second sliding member 420 along the second direction.

[0053] Therefore, by rotating the first screw rod 441 and the second screw rod 451, the second sliding member 420 can be moved along the first direction and the second direction relative to the base 310, and since the photographing member 430 is fixed on the second sliding member 420, the photographing member 430 can be moved along the first direction and the second direction relative to the base 310 following the second sliding member 420. The photographing member 430 can be a CCD camera or the like.

[0054] When it is necessary to adjust the position of the ejection hole 211 on the plurality of nozzle assemblies 200 in the ink ejection mechanism 10, the following operation steps can be adopted:

[0055] In the first step, all the nozzle assemblies 200 on the ink ejection mechanism 10 are taken out of the positioning cavities 110 of the base plate 100, and the base plate 100 is placed on the second work station 3312, so that the second positioning member 520 positions the base plate 100 along the first direction and the second direction, and the base plate 100 is fixed on the carrier 330.

[0056] In the second step, one nozzle assembly 200 is placed on the first work station 3311, so that the first positioning member 510 positions the mounting base 220 of the nozzle assembly 200 along the first direction and the second direction, and the positioned mounting base 220 is fixed on the carrier 330. At this time, the first screw rod 441 and the second screw rod 451 are rotated, so that the photographing member 430 is located below the first through hole 333. Then the first screw rod 441 is rotated, so that the photographing member 430 moves along the first direction by a certain distance. The photographing member 430 will collect the image of the ejection hole 211 through the first through hole 333, and transmit the photographed image to the control screen. According to the straight line movement of the photographing member 430 along the first direction, the control screen can present a first reference straight line 11 extending along the first direction. Then the first abutting member of the first fine adjustment unit 230 is adjusted, so that the position of the nozzle 210 relative to the mounting base 220 in the second direction is finely adjusted, so that the edge 2112 of the photographed image of the ejection hole 211 extending along the first direction in the control screen is parallel to or coincides with the first reference straight line 11, so that the length direction of the ejection hole 211 extends along the first direction. In short, when the nozzle assembly 200 is in the first work station 3311, the movement of the photographing member 430 along the first direction and the photographed image of the ejection hole 211 are used to make the ejection hole 211 extend along the first direction, so as to avoid the ejection hole 211 extending along a direction at an angle with the first direction. After the nozzle 210 is adjusted in the first work station 3311, the nozzle assembly 200 is unloaded from the first work station 3311, and the unloaded nozzle assembly 200 is transferred to one positioning cavity 110 on the base plate 100 in the second work station 3312.

[0057] Thirdly, the second step is repeated multiple times, and each of the nozzle assemblies 200 after being adjusted in the first station 3311 is transferred to a different positioning cavity 110 on the substrate 100 in the second station 3312.

[0058] Fourthly, the first screw rod 441 and the second screw rod 451 are rotated, so that the camera module 430 is located below the first through hole 333 and also below a row of nozzles formed by a row of nozzle assemblies 200 arranged in the first direction, and the camera module 430 moves a certain distance in the first direction, so that the camera module 430 collects an image of the row of nozzles through the second through hole 334 and transmits the image to the control screen. According to the linear movement of the camera module 430 in the first direction, the control screen can present a first reference straight line 11 extending in the first direction. Then, different first abutting members on the row of nozzle assemblies are adjusted, so that the positions of different nozzles 210 on the row of nozzle assemblies in the second direction are finely adjusted, so that the edges 2112 of all the nozzles 211 in the row of nozzles extending in the first direction coincide with the first reference straight line 11 or are equal in distance to the first reference straight line 11, and then the edges 2112 of all the nozzles 211 in the row of nozzles extending in the first direction are on the same straight line.

[0059] Fifthly, the fourth step is repeated multiple times, so that the edges 2112 of all the nozzles 211 in each row of nozzles on the substrate 100 extending in the first direction are on the same straight line. That is, the movement of the camera module 430 in the first direction and the image of the nozzles 211 are used to make the edges 2112 of the nozzles 211 arranged in the first direction extending in the first direction on the same straight line, so that the arrangement of the nozzles 211 on the ink jet mechanism 10 finally satisfies the first condition.

[0060] In the sixth step, the second screw rod 451 is rotated to move the photographing member 430 to one of the specified positions in the first direction, and the photographing member 430 is moved in the second direction by a certain distance so that the photographing member 430 passes below the rows of the nozzles 211 in the specified position. The photographing member 430 collects images of different nozzles 211 and transmits the images to the control screen. According to the straight movement of the photographing member 430 in the second direction, the control screen can present a second reference straight line 12 extending in the second direction, and then the second abutting member of the second fine adjustment unit 240 is adjusted to finely adjust the position of the nozzle 210 relative to the mounting seat 220 in the first direction, so that the edges of the images of the nozzles 211 formed by the photographing in the control screen extend in the second direction and fall on the second reference straight line 12, thereby ensuring that the gap between any two adjacent nozzles 211 in the first direction in the two adjacent rows of nozzles 211 in the second direction is zero, i.e., the edges of the adjacent nozzles 211 in the second direction are located on the same straight line.

[0061] In the seventh step, the second screw rod 451 is rotated to move the photographing member 430 to another specified position in the first direction, and the related steps in the sixth step are repeated, i.e., the movement of the photographing member 430 in the second direction and the photographing of the nozzles 211 are referred to, so that the gap between any two adjacent nozzles 211 in the first direction in the two adjacent rows of nozzles 211 in the second direction is zero, and finally the arrangement of the nozzles 211 on the ink jet mechanism 10 meets the second condition.

[0062] Since the arrangement of the nozzles 211 on the ink jet mechanism 10 meets the first condition and the second condition at the same time under the action of the adjustment device 20. At this time, the substrate 100 on the ink jet mechanism 10 can be unloaded from the second work station 3312, and the ink jet mechanism 10 can be installed on the ink jet printer for printing.

[0063] If the first fine adjustment unit 230 and the second fine adjustment unit 240 are directly adjusted manually according to experience, so that the arrangement of the nozzles 211 meets the first condition and the second condition at the same time, it will need to be adjusted repeatedly many times, and it is difficult to ensure that the arrangement of the nozzles 211 meets the first condition and the second condition at the same time accurately, which will affect the efficiency and accuracy of the position adjustment of the nozzles 211.

[0064] The above embodiment uses the assistance of the adjustment device 20 to adjust the position of the nozzles 211. The adjustment mechanism 400 in the adjustment device 20 provides a good adjustment standard for the position adjustment of the nozzles 211, so that the position adjustment of the nozzles 211 has a certain scientific basis. On the one hand, the working efficiency of the position adjustment of the nozzles 211 can be improved, and on the other hand, the accuracy of the position adjustment of the nozzles 211 can be improved, i.e., the efficiency and accuracy of the position adjustment of the nozzles 211 can be improved at the same time.

[0065] The present application also provides an inkjet device, which comprises an inkjet printer and the above-mentioned adjusting device 20, the inkjet printer comprises the inkjet mechanism 10, and the adjusting device 20 adjusts the position of the ink ejection hole 211 in the inkjet mechanism 10. Thus, the edges of the ink ejection holes 211 arranged along the first direction extend along the same straight line, and the edges of the ink ejection holes 211 arranged along the second direction extend along the same straight line.

[0066] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not contradict each other, they should be considered as falling within the scope of the present application.
