Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing, and particularly relates to an automatic deviation correction docking system for a printhead module and an inkjet printing device. Background Art

[0002] The inkjet printing technology has broad application prospects in many manufacturing fields such as information, energy, medical, and national defense, and is increasingly applied to flexible device fields such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, and smart skins.

[0003] In related technologies, in order to improve the inkjet printing efficiency and meet the printing requirements of high resolution, multiple printheads are installed together in a printhead mounting seat to form a printhead module with a printhead matrix, and then the printhead module is installed on an inkjet printing device. Subsequently, by moving the entire printhead module, the multiple printheads can be synchronously moved to achieve more efficient inkjet printing work. At the same time, in order to ensure the smooth execution of inkjet printing work, it is also necessary to ensure that the arrangement direction of each column of printheads is consistent with the printing direction of the printhead work. Meanwhile, in practical applications, the printhead module needs to be regularly maintained or replaced to ensure the printing effect, so the disassembly and installation processes of the printhead module are required.

[0004] Currently, the printhead module is often installed on the inkjet printing device by manual installation. However, due to the relatively complex structure of such high-precision inkjet printing devices, the operator's vision is limited during installation. Even if there is a certain docking margin between the docking part on the printhead module and the connection structure on the inkjet printing device, it is difficult to directly align and connect the docking part on the printhead module with the connection structure on the inkjet printing device during the installation process. At the same time, after the printhead module is installed, due to the docking margin between the connection structure and the docking part, it is also easy to cause a slight error in the arrangement direction of the printhead module relative to the printing direction. Summary of the Invention

[0047] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0048] An automatic deviation correction and docking system for a printhead module and an inkjet printing device provided by the present application. The key inventive point lies in that the printhead module is first preliminarily positioned by relying on the positioning reference part on the carrier seat and the pre-positioning component, so that the error of the printhead module relative to the connection part of the inkjet printing device is small before automatic docking. At the same time, during the process of automatically transporting the printhead module to dock with the connection part, the position of the printhead module will be further guided and adjusted, so that it can gradually move within the bearing surface until the docking part is aligned with the connection part, realizing smooth docking. At the same time, when there is an error between the arrangement direction of the printhead module and the printing direction, the arrangement direction of the printhead module will be adjusted according to the actually detected parallelism deviation. Finally, the printhead module can be automatically and quickly installed on the inkjet printing device, and at the same time, the installation accuracy of the printhead module can be automatically adjusted, ensuring that the inkjet printing work can be carried out efficiently and smoothly, providing a basis for the realization of the overall automation technology of the inkjet printing device.

[0049] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0050] In the first aspect, referring to Figure 1 , an embodiment of the present application provides an automatic deviation correction and docking system for a printhead module 8, which includes a mounting frame 1, a loading device 3, a first deviation correction component 4, and a second deviation correction component 5. Among them, a printhead mounting plate 2 is provided on the mounting frame 1 and is used for docking and mounting the printhead module 8. The loading device 3 is used for automatically transporting the printhead module 8 until the printhead module 8 is mounted on the printhead mounting plate 2. The first deviation correction component 4 is used to adjust the position of the printhead module 8 during the transportation process of the printhead module 8. The second deviation correction component 5 is used to adjust the arrangement angle of the printhead module 8 after the printhead module 8 is mounted on the printhead mounting plate 2.

[0051] Specifically, the mounting frame 1 is a partial structure in the inkjet printing device for docking and mounting the printhead module 8. In some embodiments, since the printhead module 8 needs to be translated as a whole when the printhead module 8 is installed or performs inkjet work, the mounting frame 1 will be movably arranged on the inkjet printing system so as to be able to move in one or more directions. Since the technical solution protected by the present application mainly focuses on how to adjust the parallelism of the printhead module 8 relative to the target direction in the installation plane and does not involve the installation position of the printhead module 8 in multiple directions, the specific setting form of the mounting frame 1 in the inkjet printing system is not specifically described and limited in the present application;

[0052] Referring to Figure 2 and Figure 3, the nozzle mounting plate 2 is rotatably arranged on the mounting frame 1, and is provided with a connecting portion 21 for docking and fixing the nozzle module 8. When the nozzle module 8 is installed, it can form a docking fit with the nozzle mounting plate 2 through the connecting portion 21, so as to realize the rotational installation of the nozzle module 8 on the mounting frame 1. At the same time, in this embodiment, when the nozzle module 8 is installed on the mounting frame 1, it is vertically installed with the inkjet direction pointing vertically downward, and the rotation axis of the nozzle mounting plate 2 is parallel to the inkjet direction of the nozzle module 8 in the docking state, that is, the rotation axis of the nozzle mounting plate 2 is vertically arranged.

[0053] Specifically, the nozzle mounting plate 2 is in a rectangular frame-like structure in this embodiment, and an installation window 20 is formed in the middle thereof for the top structure of the nozzle module 8 to vertically pass through upward. The connecting portion 21 specifically includes four electric grippers 210 installed on the nozzle mounting plate 2 in this embodiment. At the same time, docking holes 211 vertically penetrating the nozzle mounting plate 2 are provided and are aligned with the electric grippers 210 one by one. Corresponding to the docking holes 211 and the electric grippers 210, the docking portion 80 on the nozzle module 8 is specifically four docking pins 800 arranged on the top surface of the nozzle module 8. Furthermore, during the installation process, after controlling the nozzle module 8 to move vertically until the four docking pins 800 are aligned and inserted into the docking holes 211, the electric grippers 210 can be controlled to clamp and fix the docking pins 800, so as to realize the fixed installation of the nozzle module 8 at the bottom of the nozzle mounting plate 2.

[0054] Since the rotation axis of the nozzle mounting plate 2 is parallel to the inkjet direction of the nozzle module 8 in the docking state, when the nozzle mounting plate 2 is rotated, it will not affect the inkjet direction of the nozzle module 8 thereon and the position of the nozzle module 8 in the vertical direction, and only the angle of the nozzle module 8 in the arranged plane can be changed, and the influence on the position accuracy of the nozzle module 8 in other directions during the angle adjustment process can be reduced as much as possible.

[0055] Refer to Figure 1 and Figure 4, the loading device 3 is specifically arranged below the mounting frame 1 and the nozzle mounting plate 2, and includes a conveying component 30, a pre-positioning component 32 and a bearing seat 31. The bearing seat 31 is fixedly connected to the conveying component 30. The bearing seat 31 includes a bearing surface 310 provided on its top, and the bearing surface 310 is used to bear the nozzle module 8. The conveying component 30 is configured to convey the bearing seat 31 along a set conveying line at least in a first direction, a second direction and a docking direction that are perpendicular to each other in pairs until the nozzle module 8 on the bearing seat 31 is docked and fixed with the connecting portion 21. In this embodiment, the first direction and the second direction are specifically two perpendicular directions in the horizontal plane, and the docking direction is the vertical direction. For the convenience of understanding, the first direction, the second direction and the docking direction are the X, Y, and Z directions in the figure respectively. In some embodiments, the conveying device may only drive the bearing tooling in the first direction, the second direction and the docking direction. For example, through cylinder assemblies, hydraulic cylinder assemblies or telescopic rod members in three directions. In other embodiments, the conveying device may also have more degrees of freedom in other directions, such as a multi-link robotic arm assembly, etc. The present application does not limit this here.

[0056] Further, when the loading device 3 conveys the bearing seat 31 according to the set conveying line, it successively includes a first stage and a second stage. Among them, the first stage includes conveying the bearing seat 31 to a set initial alignment position. The initial alignment position is specifically the position where the docking portion 80 of the nozzle module 8 and the connecting portion 21 are aligned in the docking direction determined in advance by the technician according to the standard part of the nozzle module 8 below the nozzle mounting plate 2. The second stage is specifically to convey the bearing seat 31 in the initial alignment position along the docking direction of the nozzle module 8 and the connecting portion 21 until the nozzle module 8 is connected to the connecting portion 21.

[0057] Finally, the loading device 3 can first convey the bearing seat 31 together with the nozzle module 8 thereon to the pre-calibrated initial alignment position, and then lift the bearing seat 31 and the nozzle module 8 vertically to make it gradually approach the nozzle mounting plate 2 above until it finally completes docking with the connecting portion 21 on the nozzle mounting plate 2.

[0058] In addition, referring to Figure 4 , to further ensure that different nozzle modules 8 on the bearing surface 310 can smoothly move to the initial alignment position, a positioning reference portion 33 is provided on the bearing surface 310, and the pre-positioning component 32 in the loading device 3 is used to drive and position the nozzle module 8 to cooperate with the positioning reference portion 33.

[0059] Specifically, referring to Figure 5, the positioning reference portion 33 in this embodiment includes a carrier box 330 placed on the carrier surface 310. The top surface of the carrier box 330 is open, and an insertion alignment structure is provided between its bottom surface and the carrier surface 310 to ensure that the carrier box 330 can always be placed on the carrier surface 310 at a fixed position. At the same time, the space inside the carrier box 330 is larger than the nozzle module 8 in both the first direction and the second direction, so that when the nozzle module 8 is placed and dropped into the carrier box 330, there is still room for movement in the first direction and the second direction.

[0060] The pre-positioning assembly 32 in this embodiment includes a first pushing assembly 320 and a second pushing assembly 321 that push the nozzle module 8 to move in the first direction and the second direction. Among them, the first pushing assembly 320 is specifically a ball plunger provided on one inner wall of the carrier box 330 in the first direction. It realizes pushing the nozzle module 8 to contact the other inner wall in the first direction through the elastic ball head at its end, so as to complete the driving and positioning of the nozzle module 8 in the first direction. The second pushing assembly 321 is specifically a pushing cylinder provided outside the carrier box 330. The pushing cylinder is arranged on the carrier seat 31, and the output shaft of the pushing cylinder is arranged along the second direction and is used to push against the side wall of the nozzle module 8 extending out of the top opening of the carrier box 330, so that the nozzle module 8 can finally be pushed to contact one inner wall of the carrier box 330 in the second direction, realizing the positioning of the nozzle module 8 in the second direction. Therefore, through the cooperation of the pre-positioning assembly 32 and the positioning reference portion 33, it is realized that after the operator only places the nozzle module 8 in the carrier box 330, the pre-positioning assembly 32 can be used to perform preliminary positioning of the nozzle module 8 according to a unified standard. Subsequently, the nozzle module 8 can be automatically conveyed to the initial docking position under the action of the conveying assembly 30, and the nozzle module 8 can be controlled to be docked and fixed with the connecting portion 21 on the nozzle mounting plate 2 at the further initial docking position.

[0061] Furthermore, referring to Figure 1 , in order to avoid errors in the actual positions of the docking portions 80 on different nozzle modules 8 due to structural dimension errors in different nozzle modules 8, the present application provides a first deviation correction assembly 4 to further adjust the position of the nozzle module 8 in the second stage of the conveying process of the nozzle module 8. The first deviation correction assembly 4 includes a guiding portion 40 and a cooperating portion 41 respectively provided on the nozzle mounting plate 2 and the nozzle module 8. The guiding portion 40 and the cooperating portion 41 are configured to form a guiding cooperation when the nozzle module 8 and the connecting portion 21 are continuously approaching and contacting each other in the second stage, and when the nozzle module 8 and the connecting portion 21 are further approaching relatively, the guiding portion 40 guides the position of the nozzle module 8 in the carrier surface 310, so that the nozzle module 8 gradually moves to align its docking portion 80 with the connecting portion 21 while approaching the connecting portion 21.

[0062] Furthermore, the guiding portion 40 and the mating portion 41 are in contact with each other in the second stage and form an inclined surface transmission fit, and during the inclined surface transmission process, the nozzle module 8 can be driven to move at least in a first direction and a second direction within the bearing surface 310, and the first direction and the second direction are perpendicular to each other;

[0063] And the pre-positioning assembly 32 is configured to maintain the positioning of the nozzle module 8 within the bearing surface 310 in the first stage and release the positioning of the nozzle module 8 in the second stage.

[0064] Specifically, the inclined surface fit after the contact between the guiding portion 40 and the mating portion 41 is utilized to guide the nozzle module 8 to move in the first direction and the second direction within the bearing surface 310, so that the docking portion 80 on the nozzle module 8 can finally be aligned with the connecting portion 21 on the nozzle mounting plate 2, and thus the nozzle module 8 and the nozzle mounting plate 2 can be successfully docked in the second stage.

[0065] In addition, to ensure that the nozzle module 8 can move smoothly in the second stage, the pre-positioning assembly 32 will cooperate to release the positioning of the nozzle module 8 in the second stage. Specifically corresponding to this embodiment, it is reflected that the second pushing member will separate from the nozzle module 8 at the beginning of the second stage, that is, it will no longer press and limit the nozzle module 8 in the second direction, so that the nozzle module 8 has a movable space in the second direction. Since the nozzle module 8 is positioned by the elastic driving form of the ball head plunger in the first direction, when the guiding portion 40 and the mating portion 41 perform inclined surface transmission in the first direction, they can drive the nozzle module 8 to compress the ball head plunger and move in the first direction.

[0066] In this embodiment, referring to Figure 2 and Figure 4The guide portion 40 includes a plurality of guide holes 400 provided on the nozzle mounting plate 2, and the matching portion 41 includes a bevel pin 410 provided on the nozzle module 8 and corresponding to the guide holes 400 one by one. Specifically, two guide holes 400 are provided, and are distributed in two diagonal areas of the nozzle mounting plate 2. A guide bevel is provided around the end of the bevel pin 410. The guide bevel is used to form a bevel match with the nozzle mounting plate 2 when contacting the hole edge of the guide hole 400. Then, as the nozzle mounting plate 2 and the nozzle module 8 approach each other, the bevel drives the nozzle module 8 to move, so that the bevel pin 410 gradually moves until its pin body can be aligned with the guide hole 400. At the same time, in order to ensure that the bevel pin 410 and the guide hole 400 can more easily form a bevel transmission effect, the bottom edge of the guide hole 400 is set in a curved surface, so that it can more easily produce relative sliding when contacting the guide bevel, thereby driving the bevel pin 410 and the nozzle module 8 to move toward the center of the guide hole 400. In addition, it should be noted that the vertical length of the bevel pin 410 is greater than that of the docking pin 800, so that the bevel pin 410 can first be inclined with the guide hole 400 before the docking pin 800 moves to the plane where the docking hole 211 is located, thereby guiding the docking pin 800 to be smoothly docked into the docking hole 211, so that the nozzle module 8 can be smoothly connected to the electric clamp 210.

[0067] Reference Figure 2 and Figure 6 The second deviation correction component 5 provided in the present application includes an angle driving component 50 and an angle detection component, wherein the angle detection component is used to detect the parallelism deviation of the nozzle module 8 in the connected state relative to the preset printing direction, and the angle driving component 50 is transmission-connected to the nozzle mounting plate 2, and is used to drive the nozzle mounting plate 2 to rotate according to the parallelism deviation obtained by the detection.

[0068] Furthermore, the angle driving member 50 includes an output head 500 that can move in a forward driving direction and a reverse driving direction, and the output head 500 is connected to a pushing end 502, and the pushing end 502 is used to push the nozzle mounting plate 2 to rotate, and the pushing end 502 acts on the nozzle mounting plate 2 at a distal torque action area away from the rotation axis of the nozzle mounting plate 2.

[0069] Among them, the transmission cooperation between the driving end 502 and the nozzle mounting plate 2 is specifically that when the driving end 502 moves at least along one of the driving directions, it can push the nozzle mounting plate 2 to rotate in one rotation direction, such as clockwise; and when the driving end 502 is driven to move in the other direction, in some embodiments, it may not form a transmission cooperation with the nozzle mounting plate 2, realizing that the driving end 502 gradually moves away from the nozzle mounting plate 2; in other embodiments, in this direction, there may also be a transmission cooperation, realizing that the driving end 502 can drive the nozzle mounting plate 2 to rotate in the opposite direction, such as counterclockwise; and whether the driving end 502 needs to form a transmission cooperation with the nozzle mounting plate 2 in both driving directions depends on the specific angle adjustment requirements of the nozzle module 8 in different embodiments. For example, in some embodiments, the initial installation position of the nozzle module 8 has a relatively large parallelism deviation from the target direction and the parallelism deviation is pre-fixed on one side of the target direction, so that any nozzle module 8 needs to be rotated and adjusted in the same direction after installation. In this case, only the driving end 502 needs to be able to drive the nozzle mounting plate 2 to rotate in one driving direction, and there is no need to establish a transmission cooperation relationship in the other direction; in other embodiments, the parallelism deviation of the initial installation position of the nozzle module 8 from the target direction is relatively small and may occur on both sides of the target direction. At this time, the driving end 502 can be in transmission cooperation with the nozzle mounting plate 2 in both directions, realizing that it can actively drive the nozzle mounting plate 2 to rotate in two different directions, so as to adjust different parallelism deviations on both sides of the target direction.

[0070] In addition, when the driving end 502 pushes on the nozzle mounting plate 2, its acting area is specifically the distal torque acting area on the nozzle mounting plate 2 that is farthest from the rotation axis. Specifically, the distal torque acting area is the edge area or corner area on the nozzle mounting plate 2 that is farthest from its rotation axis, and the area range corresponds to the space required by the structures of the driving end 502 and the nozzle mounting plate 2 when they form a transmission cooperation, which is not specifically limited here; in this embodiment, since the nozzle mounting plate 2 is a rectangular frame-like structure, the distal torque acting area is specifically the corner area on the surface of the nozzle mounting plate 2 that is farthest from the rotation axis. In other embodiments, such as the nozzle mounting plate 2 with a circular plate surface, the distal torque acting area is specifically the annular area on the surface of the nozzle mounting plate 2 that is farthest from the rotation axis; thus, through the distal torque acting area, the torque when the driving end 502 pushes the nozzle mounting plate 2 to rotate is increased, thereby effectively reducing the driving force required for the driving end 502 to drive the nozzle mounting plate 2 to rotate, that is, reducing the driving load of the output head 500. At the same time, the driving distance of the nozzle mounting plate 2 per unit driving distance is also effectively reduced, that is, the driving accuracy of the nozzle mounting plate 2 is improved, enabling it to quickly and accurately adjust for small-scale parallelism errors.

[0071] Optionally, in some embodiments, in order to ensure the stable arrangement of the nozzle mounting plate 2 and the nozzle module 8 on the mounting frame 1, the mounting frame 1 includes a bearing plate 10 for horizontally placing the nozzle mounting plate 2, and the bearing plate 10 is a rectangular frame-shaped structure matching the nozzle mounting plate 2, so that the peripheral edges of the nozzle mounting plate 2 can be supported by the bearing plate 10; at the same time, the docking window formed in the bearing plate 10 is larger than the installation window 20, and the projections of the installation window 20, the connecting portion 21 and the guide portion 40 on the horizontal plane are all inside the docking window, so as not to affect the docking of the bottom surface of the nozzle mounting plate 2 with the nozzle module 8. The rotating column 100 between the mounting frame 1 and the nozzle mounting plate 2 is arranged in a corner area of ​​the bearing plate 10, and the distal torque action area on the nozzle mounting plate 2 is in the diagonal area of ​​the rotating column 100.

[0072] Furthermore, since the bottom surface of the nozzle mounting plate 2 and the top surface of the carrier plate 10 have a certain flatness error, when the nozzle mounting plate 2 is placed on the carrier plate 10, there is an objective fit gap in some areas between the two. Therefore, there is a certain precision error between the vertical position of the nozzle mounting plate 2 and the nozzle module 8 thereon and the required standard position. In order to ensure that the nozzle module 8 can be used smoothly in subsequent work, the precision error here still needs to be further controlled. Therefore, in order to ensure that the nozzle module 8 can have a more precise position guarantee in the vertical direction after the angle adjustment is completed on the nozzle mounting plate 2, a clamping assembly 6 is also provided above the nozzle mounting plate 2, referring to Figure 3 The clamping assembly 6 is installed on the mounting frame 1, and includes a pressing end 60 and a pressing driving member 61 for driving the pressing part to rise and fall in the vertical direction. The pressing end 60 is driven to rise and fall under the action of the pressing driving member 61, so that the nozzle mounting plate 2 can be tightly pressed onto the supporting plate 10, so as to fully compress the gap between the nozzle mounting plate 2 and the supporting plate 10, and further ensure the vertical position accuracy of the nozzle module 8.

[0073] Specifically, refer to Figure 3 , the pressing drive member 61 in this embodiment is a pressing cylinder installed on the mounting frame 1. In order to realize the fixed installation of the pressing cylinder, a cylinder fixing frame 11 is fixedly installed above the carrier plate 10. When the cylinder fixing frame 11 is arranged, a gap is left between it and the nozzle mounting plate 2 on the carrier plate 10 to ensure that the nozzle mounting plate 2 can rotate smoothly. The pressing cylinder is fixed on the cylinder fixing frame 11 and is located above the nozzle mounting plate 2, and its output shaft points vertically downward to the nozzle mounting plate 2. The pressing end 60 is specifically a clamping block connected to the end of the output shaft of the pressing cylinder, which can realize that the clamping block can be pressed vertically downward on the nozzle mounting plate 2 through the driving action of the pressing cylinder, so as to achieve the purpose of eliminating the gap between the nozzle mounting plate 2 and the carrier plate 10 as much as possible.

[0074] However, it should be further noted that although the gap caused by the flatness error between the bottom surface of the nozzle mounting plate 2 and the top surface of the carrier plate 10 can be effectively eliminated and reduced by extrusion, during the elimination of the gap area between the two, the two contacting surfaces may also exhibit a beveled transmission fit due to uneven protrusions under the action of the downward pressure. Since the carrier plate 10 is a fixed structure on the mounting frame 1, the relative movement between the two will cause the beveled transmission between the carrier plate 10 and the nozzle mounting plate 2 to be reflected only in the form of the nozzle mounting plate 2 rotating around the rotating column 100. That is, when the pressing assembly 6 presses down the carrier plate 10 and the nozzle mounting plate 2, the nozzle mounting plate 2 may rotate and cause an angular deviation of the nozzle module 8, further affecting the angle of the nozzle module 8 that has been corrected in the layout plane and further affecting the final inkjet printing work.

[0075] Based on the above problems, further, referring to Figure 6 , in this embodiment, a transmission block 51 is fixedly provided on the distal torque action area of the nozzle mounting plate 2. The transmission block 51 is provided with clamping walls 510 whose two surfaces are parallel to the rotation axis of the nozzle mounting plate 2, and a clamping area is formed by the interval between the two clamping walls 510. Specifically, the two clamping walls 510 are parallel to each other and are vertically arranged perpendicular to the nozzle mounting plate 2, and the clamping area formed between the two is used for arranging the pushing end 502. In this embodiment, as the pushing end 502, it will come into contact and press against both clamping walls 510 in the clamping area. That is, when the pushing end 502 follows the output head 500 and moves in two driving directions in this embodiment, it will be able to drive the nozzle mounting plate 2 to rotate in cooperation; furthermore, since both sides of the driving end are in contact and pressed against the clamping walls 510, when the output head 500 is not driven and is automatically locked, the driving end will not be able to change its position, that is, it will not be able to drive the clamping walls 510 on both sides to rotate either, which is reflected in that the transmission block 51, the nozzle mounting plate 2, and the nozzle module 8 cannot change their positions in the circumferential direction of rotation, and the driving end can only slide relative to the clamping walls 510 on both sides in the vertical direction, that is, it avoids possible slight angular changes of the nozzle module 8 at this time. Finally, by using the transmission block 51 to form a contact fit with the pushing end 502 from both sides, it effectively prevents the nozzle mounting plate 2 from deviating in angle during the process of being pressed onto the carrier plate 10.

[0076] Further, the output head 500 is rotatably arranged in a spin manner on the angle driving member 50, and the rotation axis of the output head 500 is parallel to the rotation axis of the nozzle mounting plate 2. The angle driving member 50 further includes a transmission rod 501 eccentrically connected to one end of the end face of the output head 500. The transmission rod 501 is parallel to the rotation axis of the nozzle mounting plate 2 and is connected to the pushing end 502 at the other end.

[0077] Specifically, the angle driving member 50 is a driving motor capable of rotating bidirectionally. When it does not actively drive the output head 500 to rotate, the output head 500 will remain in a locked state. By setting the movement trajectory of the pushing end 502 in the form of circumferential rotation, it is possible to effectively reduce the space occupied by the movement path of the pushing end 502 when pushing the nozzle mounting plate 2. At the same time, arranging the angle driving member 50, the output head 500, the transmission rod 501, and the pushing end 502 vertically will further reduce the space occupied in the horizontal direction around the nozzle module 8. Furthermore, for an inkjet printing device having multiple nozzle modules 8, since multiple nozzle modules 8 therein need to be installed and arranged in the same horizontal plane, and the interval between adjacent nozzle modules 8 also needs to meet the pitch accuracy requirements between individual nozzles, the interval space between adjacent nozzle modules 8 in the horizontal direction is very limited. However, the specific arrangement form of the angle driving member 50 and the pushing end 502 in this embodiment can effectively apply to this scenario, significantly reducing the impact on the installation and arrangement of multiple nozzle modules 8 in the horizontal direction, and ensuring that the overall structure of the inkjet printing device is more reasonable and compact.

[0078] Further, the pushing end 502 is rotatably installed at the bottom end of the transmission rod 501, and the rotation axis is coaxial with the transmission rod 501. This setting enables a rolling fit to be formed between the pushing end 502 and the two clamping walls 510, reducing the driving resistance between the pushing end 502 and the nozzle mounting plate 2, and further reducing the load required for the angle driving member 50 to drive the nozzle mounting plate 2 to rotate.

[0079] Further, the angle detection component is specifically a visual image collector (not shown in the figure) in this embodiment. By collecting the visual image of the bottom surface of the nozzle module 8 after installation and analyzing the arrangement direction information of multiple nozzles therein, and then comparing it with the pre-calibrated printing direction, the parallelism deviation of the nozzle module 8 can be obtained. At this time, the driving amount that the angle driving member 50 needs to execute can be analyzed based on the parallelism deviation, and the nozzle mounting plate 2 can be controlled to rotate by a corresponding angle through the angle driving member 50.

[0080] Further, in some embodiments, referring to Figure 6 , a rotating column 100 arranged vertically is provided on the bearing plate 10 of the mounting frame 1. At the same time, a mounting hole for the rotating column 100 to pass through is provided on the nozzle mounting plate 2. Through the rotational passing fit between the nozzle mounting plate 2 and the rotating column 100, the nozzle mounting plate 2 is rotatably installed on the mounting frame 1 with a vertical rotation axis. At the same time, the nozzle mounting plate 2 can also move in the vertical direction relative to the rotating column 100.

[0081] In addition, an installation cap 101 is provided at the top end of the rotating column 100 passing through the nozzle installation plate 2. A buffer interval is left between the installation cap 101 and the nozzle installation plate 2. A pressing spring 102 is sleeved on the rotating column 100 within the buffer interval, and the pressing spring 102 is in a compressed state and provides a downward pressure to the nozzle installation plate 2.

[0082] Specifically, due to the vertical arrangement of the transmission rod 501 and the driving end, and the rotation in the horizontal plane to push the nozzle installation plate 2 to rotate, theoretically, it is required that the driving end only rotates in the horizontal plane, and the applied thrust acts perpendicularly on the nozzle installation plate 2 to achieve only applying a thrust in the horizontal direction to the nozzle installation plate 2. However, in practice, there are some structural errors or installation errors objectively. For example, there is a vertical precision error when the transmission rod 501 extends vertically, an installation precision error between the rotation axis of the output head 500 and the vertical direction, and a perpendicularity error when the pushing end 502 contacts the clamping wall 510, etc. All of these may cause the pushing end 502 to apply an inclined thrust to the nozzle installation plate 2. When there is also a vertically upward component force in addition to the horizontal direction of the thrust, it will cause the nozzle installation plate 2 to have the possibility of moving relative to the rotating column 100 in the vertical direction, that is, there is a possibility of causing a change in the installation precision of the nozzle module 8 in the vertical direction. Therefore, in this embodiment, further, a pressing spring 102 is sleeved on the rotating column 100 on the nozzle installation plate 2, so that it can provide a certain downward pressure to the nozzle installation plate 2 in the vertical direction, realizing a certain degree of balance of the vertically upward component force received by the nozzle installation plate 2, and further avoiding the nozzle installation plate 2 moving a large distance upward in the vertical direction during the rotation process, thereby affecting the position precision of the nozzle module 8 in the vertical direction.

[0083] Further, referring to Figure 3 , the automatic deviation correction docking system of the nozzle module 8 further includes an adapter installation plate 7 and an adapter docking driving member 71. Among them, an adapter female head 70 is installed on the adapter installation plate 7 for docking with the adapter male head 81 on the nozzle module 8.

[0084] Among them, the adapter installation plate 7 is arranged on the installation frame 1 and is located above the nozzle module 8 in the completed docking state. The adapter female head 70 is vertically installed on the adapter installation plate 7, so that its insertion direction is the same as the docking direction of the nozzle module 8 and is in the vertical direction. At the same time, a vertical installation slide rail is provided on the installation frame 1, and the adapter installation plate 7 is installed on the installation slide rail, realizing that the adapter female head 70 is arranged to be movable up and down. At the same time, the adapter docking driving member 71 is fixedly arranged on the installation frame 1, and it has an output end that can move vertically, and its output end is fixedly connected to the adapter installation plate 7. Furthermore, the adapter female head 70 can be driven to move up and down in the vertical direction through the adapter docking driving member 71.

[0085] Specifically, before the angle adjustment between the nozzle mounting plate 2 and the nozzle module 8 is completed, there is an error between the arrangement direction of the nozzles in the nozzle module 8 and the printing direction, resulting in misalignment between the adapter female head 70 arranged in the printing direction and the adapter male head 81 on the nozzle. Therefore, the docking process of the adapter needs to be carried out after the nozzle mounting plate 2 is installed and the angle is adjusted. In order to prevent the adapter female head 70 from hindering the angle adjustment of the nozzle module 8, the adapter docking driving member 71 will control the adapter mounting plate 7 to move away from the nozzle mounting plate 2 first at this stage, avoiding the conflict between the adapter male head 81 on the nozzle and the adapter female head 70 during the angle adjustment process. After the angle adjustment of the nozzle mounting plate 2 together with the nozzle module 8 is completed, the adapter male head 81 connected to the nozzle will also be adjusted to the standard position. At this time, by further controlling the adapter mounting plate 7 to gradually approach the nozzle module 8 to the set position through the adapter docking driving member 71, the automatic insertion of the adapter female head 70 and the adapter male head 81 can be achieved, and the automatic installation and positioning of the nozzle module 8 on the mounting frame 1 and the adapter docking can be successfully completed, ensuring smooth subsequent use.
