Description

Technical Field

[0001] This application relates to the field of inkjet printing technology, and in particular to an assembled printhead, printhead module and inkjet printing system. Background Technology

[0002] Inkjet printing technology has broad application prospects in many manufacturing fields such as information, energy, medical, and defense. With the rapid development of the technology, it has also gained more and more applications in emerging fields such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, smart skin and other flexible devices.

[0003] The core component of an inkjet printer is the inkjet printing unit. Driven by a drive shaft, the inkjet printing unit achieves full-size printing of the substrate through multiple reciprocating motions of the drive shaft. Traditional inkjet printing units typically have one printhead 2. To accommodate the printing of large-size substrates, multiple printheads 2 need to be spliced ​​together along the length of the nozzle arrangement. (See reference...) Figure 8 To increase the length of the substrate printed by each inkjet printing unit, thus accelerating the printing efficiency. To further improve printing resolution, multiple printheads 2 need to be configured for sequential printing, referring to... Figure 9 The multiple nozzles of the rear printhead 2 and the multiple nozzles of the front printhead 2 interpolate in the arrangement direction of the multiple printhead 2 to increase the density of printing ink droplets, thereby improving the printing resolution.

[0004] In related technologies, when multiple nozzles are assembled together, mounting holes are pre-set on the mounting plate for nozzle installation. The nozzles are then fixed to the mounting holes using bolts, thus achieving the assembly of multiple nozzles.

[0005] However, when the nozzles are installed onto the mounting plate via bolts and mounting holes, the installation position of the nozzles is determined by the precision of the fit between the bolts and the mounting holes. Each nozzle has a slight deviation in its installation position, and therefore, when multiple nozzles are spliced ​​together, the installation position of each nozzle will also have a deviation. The small nozzle spacing of the nozzles and the deviation in their installation positions make it difficult to interpolate or lengthen the nozzles of multiple nozzles, hindering the achievement of precise and seamless splicing of multiple nozzles.

[0007] In a first aspect, an assembled nozzle is provided, comprising:

[0008] Base;

[0013] In some embodiments, the limiting block is mounted on the base, and the length direction of the limiting block is set along the first direction. The limiting groove is formed in the nozzle component, and the length direction of the limiting groove is consistent with the length direction of the plurality of nozzles of the nozzle component. The length of the limiting groove is greater than the length of the limiting block, and the width of the limiting groove is equal to the width of the limiting block.

[0014] In some embodiments, the assembled nozzle further includes a fixing structure, through which the nozzle component is fixed to the base, the fixing structure comprising:

[0015] Multiple fixing slots are provided on the base, and the length direction of the fixing slots is arranged along the first direction;

[0016] Multiple fixing bolts are respectively inserted into multiple fixing slots, and all fixing bolts pass through the base and are threadedly connected to the nozzle component.

[0017] In some embodiments, one of the plurality of nozzle components is a fixed nozzle component, which is fixed to the base, and the positions of the other nozzle components are adjusted based on the position of the fixed nozzle component.

[0018] In some embodiments, the adjustment component includes:

[0027] The beneficial effects of the technical solution provided in this application include:

[0028] This application provides an assembled printhead. Due to the arrangement of the guide assembly structure, the length direction of multiple nozzles of the printhead is restricted when it is installed on the base, thereby ensuring that the length direction of the nozzle arrangement of each printhead is consistent, improving the assembly accuracy of multiple printheads. Since the length direction of the nozzle arrangement of the printhead is restricted when it is installed on the base, the spacing of multiple nozzles of the printhead is consistent in the length direction of the nozzle arrangement. When multiple printheads are interpolated or lengthened, the consistent spacing of the nozzles of each printhead on the base results in a better assembly effect and improved assembly accuracy. In addition, by using the adjustment component to fine-tune the printhead, the position of different printheads in the length direction of the nozzle arrangement is changed, ensuring seamless assembly of multiple printheads, eliminating assembly errors caused by installation accuracy, improving assembly accuracy, and ensuring printing accuracy.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides an assembled printhead, printhead module, and inkjet printing system. The assembled printhead utilizes a guide structure to position the printhead component along its length, and then adjusts the position of the printhead component using an adjustment assembly to eliminate assembly errors caused by installation inaccuracies. This improves the accuracy of printhead assembly and ensures printing accuracy. This application solves the technical problem in related technologies where it is difficult to achieve precise and seamless splicing of multiple printheads due to printhead installation errors.

[0046] Reference Figures 1 to 3 An assembled printhead includes a base 1, multiple printhead components 2, multiple adjustment components 3, and multiple guide structures 4. The guide structures 4 determine the length direction of the nozzle arrangement of the printhead components 2, and the adjustment components 3 fine-tune the position of the printhead components 2 along their nozzle arrangement length direction, enabling seamless splicing of multiple printhead components 2. This eliminates splicing errors caused by installation inaccuracies, improves the splicing accuracy between printhead components 2, and ensures subsequent printing quality.

[0047] Reference Figures 1 to 3 In this embodiment, multiple nozzle components 2 are mounted on a base 1, and multiple guide structures 4 correspond to the multiple nozzle components 2 respectively, ensuring that after all the nozzle components 2 are mounted on the base 1, the length direction of the nozzle arrangement of each nozzle component 2 is consistent. In this embodiment, after the nozzle components 2 are mounted on the base 1, the length direction of the nozzle arrangement of the nozzle components 2 is set along a first horizontal direction, which is the left-right direction (X-axis direction in the figure). Adjacent nozzle components 2 are spaced apart in a second horizontal direction, which is perpendicular to the first direction in this embodiment. For ease of understanding, the second direction is the front-back direction (Y-axis direction in the figure). Adjacent nozzle components 2 are spaced apart in the second direction to avoid interference during assembly.

[0048] Among them, the nozzle component 2 can be finely adjusted in the first direction by the adjustment component 3, so as to achieve high-precision seamless splicing of the nozzle component 2.

[0049] With this configuration, under the guidance structure 4, the length direction of all nozzles of the nozzle assembly 2 is aligned along the first direction. Since the spacing between the multiple nozzles of each nozzle assembly 2 is consistent, seamless splicing of multiple nozzle assemblies 2 can be achieved simply by adjusting the position of the nozzle assembly 2 in the first direction. Specifically, when multiple nozzle assemblies 2 are lengthened, the spacing between the two nozzles at the splicing point of adjacent nozzle assemblies 2 in the first direction is easily adjusted to match the spacing between adjacent nozzles in a single nozzle assembly 2 in the first direction, thus achieving seamless lengthening and splicing of multiple nozzle assemblies 2. When multiple nozzle assemblies 2 are spliced ​​together, since the nozzles of the nozzle assemblies 2 are arranged in the first direction, the spacing between the multiple nozzles of each nozzle assembly 2 in the first direction is consistent. By adjusting the position of the nozzle assemblies 2 in the first direction, the spacing between all nozzles of multiple nozzle assemblies 2 in the first direction is made consistent, thus achieving seamless interlocking assembly of multiple nozzle assemblies 2. By limiting and determining the position of the nozzle assemblies 2 in one direction and adjusting the position of the nozzle assemblies 2 in another direction, installation errors of the nozzle assemblies 2 are eliminated, and the assembly accuracy of the nozzle assemblies 2 is improved.

[0050] Reference Figures 2 to 5 Optionally, the guide structure 4 includes a limiting groove 41 and a limiting block 42. One of the limiting groove 41 and the limiting block 42 is arranged on the nozzle 2, and the other is arranged on the base 1. The nozzle 2 is slidably disposed on the base 1 through the cooperation of the limiting groove 41 and the limiting block 42. The length direction of the plurality of nozzles of the nozzle 2 is arranged in a first direction.

[0051] Specifically, if the limiting block 42 is disposed on the base 1, the length and width directions of the multiple limiting blocks 42 are consistent, preferably the length directions of the limiting blocks 42 are consistent, and the multiple limiting blocks 42 are fixed to the base 1 using bolts. The limiting groove 41 is formed in the nozzle component 2, and the length direction of the limiting groove 41 is consistent with the length direction of the nozzle arrangement of the nozzle component 2. At this time, after the nozzle component 2 is installed on the base 1 through the cooperation of the limiting groove 41 and the limiting block 42, it can be ensured that the length direction of the nozzle arrangement of the multiple nozzle components 2 is consistent. Among them, the length of the limiting groove 41 in the first direction is greater than the length of the limiting block 42 in the first direction, so as to support the sliding of the limiting block 42 in the limiting groove 41, so as to support the fine adjustment of the position of the nozzle component 2.

[0052] If the limiting block 42 is provided on the nozzle component 2, then the length or width direction of the limiting block 42 is consistent with the length direction of the nozzle arrangement of the nozzle component 2, preferably the length direction of the limiting block 42 is consistent with the length direction of the nozzle arrangement of the nozzle component 2. The limiting groove 41 is formed on the base 1, and the length directions of multiple limiting grooves 41 are consistent, all arranged along the first direction. At this time, after the nozzle component 2 is installed on the base 1 through the cooperation of the limiting groove 41 and the limiting block 42, it can be ensured that the length directions of the nozzle arrangement of multiple nozzle components 2 are consistent. Among them, the length of the limiting groove 41 in the first direction is greater than the length of the limiting block 42 in the first direction, so as to support the sliding of the limiting block 42 in the limiting groove 41, so as to support the fine adjustment of the position of the nozzle component 2.

[0053] This configuration, through the cooperation of the limiting block 42 and the limiting groove 41, achieves the longitudinal positioning of the nozzle arrangement of the nozzle assembly 2. When splicing the nozzle assembly 2, simply ensuring the cooperation of the limiting groove 41 and the limiting block 42 is sufficient, thus improving the splicing accuracy of the nozzle assembly 2. Furthermore, the installation accuracy of the limiting block 42 and the machining accuracy of the limiting groove 41 are prepared and controlled before splicing the nozzle assembly 2, and therefore do not affect the splicing efficiency of the nozzle assembly 2.

[0054] Reference Figures 2 to 5 In this embodiment, the limiting block 42 is installed on the base 1, and the length direction of the limiting block 42 is set along the first direction. The installation accuracy of the limiting block 42 is controlled manually. The limiting groove 41 is formed in the nozzle component 2. The length direction of the limiting groove 41 is consistent with the length direction of the multiple nozzles of the nozzle component 2. The length of the limiting groove 41 is greater than the length of the limiting block 42 to support the fine adjustment of the position of the nozzle component 2. The width of the limiting groove 41 is equal to the width of the limiting block 42, so as to ensure that the length direction of the nozzle arrangement of the nozzle component 2 is determined by the cooperation of the limiting block 42 and the limiting groove 41.

[0055] Reference Figures 2 to 5 The assembled nozzle also includes a fixing structure. After the nozzle component 2 is finely adjusted by the adjustment component 3, the nozzle component 2 is fixed to the base 1 by the fixing structure. The fixing structure includes multiple fixing slots 51 and multiple fixing bolts.

[0056] A fixing groove 51 is formed in the base 1, and the length direction of the fixing groove 51 is arranged along the first direction. Fixing bolts are respectively inserted into multiple fixing grooves 51, and all fixing bolts pass through the base 1 and are threadedly connected to the nozzle component 2. In this embodiment, each nozzle component 2 is connected by multiple fixing grooves 51 and fixing bolts.

[0057] During the fine-tuning of the nozzle component 2 using the adjustment component 3, the fixing bolts are released from their tightened state, allowing the fixing bolts to slide relative to the base 1. The fixing bolts slide together with the nozzle component 2 within the fixing groove 51. After the position of the nozzle component 2 is adjusted, the fixing bolts are tightened again to completely fix the nozzle component 2 and the fixing component. This ensures that the position of the nozzle component 2 does not change and guarantees a seamless splicing of multiple nozzle components 2.

[0058] Reference Figures 2 to 5 Preferably, among the multiple nozzle components 2, there is a fixed nozzle component 2a, which is fixed to the base 1, and the positions of the other nozzle components 2 are adjusted based on the position of the fixed nozzle component 2a.

[0059] Specifically, after the guide structure 4 determines the length direction of the nozzle arrangement on the base 1, the fixed nozzle component 2a is directly fixed to the base 1 with bolts. Then, referring to the position of the fixed nozzle component 2a, the position of the other nozzle components 2 is adjusted using the adjustment component 3 to achieve the splicing of multiple nozzle components 2.

[0060] This setup, with the fixed nozzle component 2a as the reference, reduces the need for adjusting the position of one nozzle component 2 and the number of adjustment components 3, thus improving adjustment efficiency.

[0061] Preferably, the fixed nozzle component 2a is located at the middle of the length direction of the multiple nozzle components 2. When it is necessary to adjust the multiple nozzle components 2, the transmission of splicing errors is avoided, thus ensuring the splicing accuracy of the multiple nozzle components 2. When there are three nozzle components 2, the middle nozzle component 2 is the fixed nozzle component 2a. At this time, the other two nozzle components 2 can be finely adjusted in position directly with the fixed nozzle component 2a, thus ensuring the splicing accuracy.

[0062] Reference Figures 1 to 3 Each nozzle component 2 has an adjustment assembly 3 arranged on both sides in the first direction. Different adjustment assemblies 3 act on the two sides of the nozzle component 2 in the first direction to fine-tune the position of the nozzle component 2 in the first direction. The adjustment assembly 3 includes an adjustment seat 31 and an adjustment screw 32.

[0063] The adjusting seat 31 is fixed to the base 1 by bolts. The adjusting screw 32 is threaded through the adjusting seat 31, and the length direction of the adjusting screw 32 is set along the first direction. The adjusting screw 32 abuts against the nozzle 2. By turning the adjusting screw 32, the nozzle 2 is pushed, thereby adjusting the position of the nozzle 2.

[0064] It is important to note that when adjusting the position of one nozzle component 2, the fixing screws on opposite sides of the nozzle component 2 must be turned simultaneously. One fixing screw pushes the nozzle component 2 forward while the other moves away from it, ensuring that both fixing screws clamp the nozzle component 2. This allows for fine-tuning of the nozzle component 2. By clamping the nozzle component 2 with two fixing screws, the movement distance of the nozzle component 2 is more easily controlled, improving the movement accuracy of the nozzle component 2 and ensuring the precision of seamless splicing.

[0065] Reference Figures 1 to 3 Furthermore, the adjustment assembly 3 also includes an elastic element 33, the two ends of which abut against the adjustment seat 31 and the nozzle component 2, respectively, and the elastic element 33 continuously abuts against the nozzle component 2. In this embodiment, the elastic element 33 includes a spring, which is sleeved on the fixing bolt. In other embodiments, the elastic element 33 includes an elastic sheet or an elastic block.

[0066] This configuration utilizes the deformation of the elastic element 33 to continuously press against the nozzle component 2, keeping the nozzle component 2 in a clamped state and preventing it from moving freely. This improves the fine-tuning accuracy of the nozzle component 2 and ensures the splicing accuracy of the nozzle component 2.

[0067] Reference Figures 6 to 7 The printhead assembly 2 includes a printing module 21 and a mounting base 22. The printing module 21 is mounted on the mounting base 22. In this embodiment, a limiting groove 41 is formed on the mounting base 22, and the printing module 21 is connected to the base 1 through the mounting base 22. Before splicing the printhead assemblies 2, the printing module 21 and the mounting base 22 are assembled, and the consistency of the assembled multiple printhead assemblies 2 is ensured, thereby ensuring the splicing accuracy of the subsequent printhead assemblies 2.

[0068] This arrangement, separating the printing module 21 and the mounting base 22, facilitates batch processing of both components and is suitable for mass production of the printhead assembly 2. Furthermore, the position of the printing module 21 relative to the base 1 is determined by the position of the mounting base 22 on the base 1, allowing for the splicing of various different printing modules 21 and improving versatility.

[0069] Reference Figures 6 to 7 Furthermore, the printhead assembly 2 also includes multiple sets of height adjustment components 23, which connect the printing module 21 and the mounting base 22. By adjusting the height of the printhead assembly 2 relative to the mounting base 22 through the height adjustment components 23, the consistency of the multiple printhead assemblies 2 is ensured. Therefore, when the printhead assembly 2 is installed on the base 1, the height consistency of the nozzles of the multiple printhead assemblies 2 is better.

[0070] The four corners of the mounting base 22 are connected to the mounting base 22 via height adjustment components 23. The height adjustment components 23 include a first bolt 231 and a second bolt 232. The first bolt 231 is threaded through the printing module 21 and abuts against the mounting base 22; the second bolt 232 passes through the printing module 21 and is threadedly connected to the mounting base 22, and the bolt head of the second bolt 232 abuts against the printing module 21.

[0071] With this configuration, the first bolt 231 and the second bolt 232 adjust the height of each corner of the printing module 21 relative to the mounting base 22 by pushing and pulling, achieving high adjustment precision. By adjusting the height of the printing module 21 relative to the mounting base 22 and adjusting the flatness of the spray surface of the printing module 21, the consistency of multiple printhead components 2 is better ensured, thereby guaranteeing the splicing accuracy of the subsequent splicing of multiple printhead components 2.

[0072] This application provides an assembled printhead. Due to the arrangement of the guide component structure, when the printhead 2 is installed on the base 1, the length direction of the multiple nozzles of the printhead 2 is restricted, thereby ensuring that the length direction of the nozzle arrangement of each printhead 2 is consistent, improving the assembly accuracy of multiple printheads. Since the length direction of the nozzle arrangement of the printhead 2 is restricted when the printhead 2 is installed on the base 1, the spacing of the multiple nozzles of the printhead 2 is consistent in the length direction of the nozzle arrangement. When multiple printheads are interpolated or lengthened, the assembly effect of the printhead 2 is better and the assembly accuracy is improved because the spacing of the nozzles of each printhead 2 on the base 1 is consistent. In addition, the adjustment component 3 is used to fine-tune the printhead 2, changing the position of different printheads 2 in the length direction of the nozzle arrangement, ensuring seamless assembly of multiple printheads 2, eliminating assembly errors caused by installation accuracy, improving assembly accuracy, and ensuring printing accuracy.
