[0051] As shown in Figure 1 And Figure 2As shown, the adjusting structure 2 is provided with a plurality of adjusting structures 2, the plurality of adjusting structures 2 are arranged at intervals along the first direction, and the interval distance between any two adjacent adjusting structures 2 is the same. Among the plurality of adjusting structures 2, any two adjacent adjusting structures 2 are staggered. The adjusting structure 2 comprises a linear moving assembly and a rotating piece 21, a plurality of linear moving assemblies are fixed on the first mounting plate 11 at intervals along the first direction, and any two adjacent linear moving assemblies are staggered, for example, the previous linear moving assembly is arranged downstream of the second direction, and the linear moving assembly adjacent to the linear moving assembly is arranged upstream of the second direction. The linear moving assembly can be a linear motion structure such as a lead screw motor. The output end of each linear moving assembly is respectively fixed with a rotating piece 21, and the output end of the rotating piece 21 rotates around a vertical direction as the rotation axis. The output end of the rotating piece 21 is fixed with the nozzle assembly structure 3. The rotating piece 21 is a controllable motor rotating device.

[0052] As shown in Figure 1 and Figure 2 , the nozzle assembly structure 3 comprises a first assembly plate 31 and a second assembly plate 32, the first assembly plate 31 is horizontally placed, the middle position of the first assembly plate 31 is fixed on the output end of the rotating piece 21, and two second assembly plates 32 are vertically fixed on both sides of the first assembly plate 31, the two second assembly plates 32 linearly form a mounting space, the nozzle 6 is mounted in the mounting space, and the two sides of the nozzle 6 are respectively fixed on the two second assembly plates 32.

[0053] As shown in Figure 3 , the nozzle 6 comprises a nozzle body and a nozzle, along the first direction, i.e. Figure 3 left and right direction, each nozzle body is provided with eight nozzle groups, each nozzle group is arranged at intervals with a plurality of nozzles, the starting position of the nozzle array in each nozzle group is correspondingly arranged, the ending position of the nozzle array in each nozzle group is correspondingly arranged, and the interval distance is the same, so that in the second direction, a plurality of nozzle groups are also formed. The second direction is the moving direction of the linear moving assembly, i.e. Figure 3 up and down direction. Among them, any nozzle 6 is close to a row of nozzles of another nozzle 6 adjacent to it, which is a first nozzle row group; the nozzle 6 adjacent to the other nozzle 6 is close to a row of nozzles of the nozzle 6, which is a second nozzle row group. For example, the row of nozzles in the horizontal direction of the leftmost nozzle at the lowermost end is the first nozzle row group, and the row of nozzles in the horizontal direction close to the uppermost end of the second nozzle from left to right is the second nozzle row group.

[0054] As shown in Figures 1 to 3 , the printing device further comprises a debugging reference plate 5.

[0055] When it is necessary to install the nozzle 6 on the nozzle assembly structure 3, the lifting structure lifts the entire printing device up and down to a suitable position, and the staff installs the nozzle 6.

[0056] The adjacent linear moving assembly drives the rotating member 21 and the nozzle assembly structure 3 to stagger displacement. Until the staggered arrangement is formed between any two adjacent nozzle assembly structures 3, the installation space is left for the staff to assemble and debug. When the nozzle 6 is installed on the nozzle assembly structure 3, the staggered arrangement of six nozzles 6 is formed, the printing width of the entire printing device is increased, and the printing efficiency is improved. And through the electric adjustment, the automatic adjustment, and the high adjustment precision, the time is saved.

[0057] When the installation is completed, the nozzles 6 need to be regulated. The debugging reference plate 5 is moved to the lower side of the nozzles 6, and a printing is performed on the debugging reference plate 5 through the nozzles, and the external regulating device scans and analyzes the printing pattern to determine the position of the nozzles, including the height of the nozzles, and then the height of the nozzles can be adjusted to the appropriate position by controlling the lifting structure to drive the base frame 1 to move up and down, and the linear moving assembly and the rotating member 21 are adjusted in the two degrees of freedom directions of the second direction and the vertical axis, respectively. The rotating member 21 drives the nozzle assembly structure 3 and the nozzle 6 to rotate, so that the connecting line of the axes of the nozzles in each row of nozzle groups arranged along the second direction on any one nozzle 6 is parallel to the first direction, and then the linear moving assembly drives the nozzle 6 to move, until the connecting line of the axes of the nozzles in the first nozzle row group of any two adjacent nozzles 6 is collinear with the connecting line of the axes of the nozzles in the second nozzle row group. For example, in the first and second nozzles need to be adjusted along from left to right, the lowermost row of nozzles of the first nozzle 6 and the uppermost row of nozzles of the second nozzle 6 are guaranteed to pass through each nozzle 6 during the printing process. Through the above setting, the nozzles on any two adjacent nozzles 6 have a connecting area in the first direction, avoiding a large gap between the nozzles of the adjacent two nozzles 6, which affects the printing quality. Figure 3

[0058] The printing device in the embodiment can be used to print hot-melt ink on the substrate. The ink is solid before use, and is melted into liquid by heating during use and is sprayed on the surface of the substrate through the nozzle 6 to form a pattern mask.

[0059] In the embodiment, the printing device can be used to print hot-melt ink on the substrate. The ink is solid before use, and is melted into liquid by heating during use and is sprayed on the surface of the substrate through the nozzle 6 to form a pattern mask. Figure 3 ​In the figure, the six nozzles from left to right are the first nozzle, the second nozzle, the third nozzle, the fourth nozzle, the fifth nozzle, and the sixth nozzle. The six nozzles are divided into three nozzle groups, and each nozzle group is provided with two staggered nozzles 6. Before printing, it is necessary to first control the rotating member 21 so that each row of nozzles in the six nozzles 6 is adjusted to be parallel to the second direction, that is, the axis line of any row of nozzles in each row of nozzles arranged along the first direction is parallel to the second direction; then control the linear moving component so that the axis line of the nozzles in the first nozzle row group is collinear with the axis line of the nozzles in the second nozzle row group, that is, the bottom row of nozzles of the first (third, fifth) nozzle 6 is aligned with the top row of nozzles of the second (fourth, sixth) nozzle 6. Compared to a single nozzle, the provision of nozzle groups can increase the printing width of the entire printing device and improve printing efficiency. Compared to a single nozzle group, the provision of multiple nozzle groups allows the substrate to pass through each nozzle group in sequence during the printing process. The blank areas between the initial printing bands formed by the initial nozzle group are gradually covered by the printing bands formed by the subsequent nozzle groups, which is conducive to reducing the blank areas between the initial printing bands, that is, it is conducive to reducing the width of the grid lines obtained by electroplating in the blank areas and improving the fineness of the grid lines. In addition, it is possible to complete the work in one printing, avoiding multiple reciprocating printings by a single nozzle, thereby improving printing efficiency.

[0060] When the adjustment is completed, the debugging reference part is withdrawn, the substrate starts to be transported, and the nozzle 6 starts to print. When a problem occurs during the printing process or the nozzle 6 needs to be adjusted, the linear motion component is restarted, the corresponding nozzle 6 is removed, and replaced or repaired.

[0061] The printing device provided in this embodiment solves the problems of the existing six-head manual assembly and debugging being troublesome and occupying a large space. By combining the adjustment mechanisms of multiple electric heads 6, the splicing work of the heads 6 can be completed automatically when they are combined, which has the characteristics of taking up little space and being easy to operate.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
