[0001] The present invention belongs to the technical field of electronic devices, and particularly relates to a method, device, equipment and storage medium for printing a dam of a display device based on multiple print heads. Background Art

[0002] In the prior art, a single needle is usually used to perform multiple back-and-forth lamination printing on the surface of a substrate to print the dam or enclosure of a display device, resulting in a problem of low printing efficiency. For example, Patent CN119458915A discloses a method for preparing a chip sealing enclosure, including: obtaining enclosure parameters, and determining a plurality of target edges and a plurality of target corners according to the enclosure parameters; controlling the print head to rotate to a preset starting position; controlling the loading mechanism to rotate, successively making the plurality of target edges perpendicular to the plane where the print head is located, and moving the print head according to the requirements of a first preset trajectory to complete the printing of the target edges in the enclosure; controlling the loading mechanism to rotate, successively making the midlines of the plurality of target corners in the same plane as the print head, and moving the print head according to the requirements of a second preset trajectory to complete the printing of the target corners in the enclosure; in the printing of the target edges, if the number of printing layers is greater than 1, then determining the printing start point and printing end point corresponding to each printing layer of the target edge according to a first preset offset distance and a second preset offset distance, and controlling the print head to perform reciprocating printing between the printing start point and printing end point corresponding to each printing layer.

[0003] Or a multi-needle module is used to print dams with different paths. In this case, each print needle in the multi-needle module still needs to use the method of multiple back-and-forth lamination printing to print the dam, and the printing efficiency is still limited. For example, Patent CN119458888A discloses a method for forming a middle frame of a display device, a method for manufacturing a display device and a printing device, and the method for forming the middle frame includes: printing the middle frame, printing the middle frame material along the edge of the printing substrate in the edge area to form the middle frame; wherein, first forming a spill prevention wall in the edge area, and then printing and filling in the area within the spill prevention wall in the edge area to form a filling layer; including: using a five-axis linkage printing device capable of adjusting the position and orientation angle of the print head, adjusting the orientation angle and position of the print head, and forming a first spill prevention wall and a second spill prevention wall on the edge on the side far from the center position of the printing substrate in the edge area and on the edge on the side close to the center position of the printing substrate in the edge area; the five-axis linkage printing device has at least two print heads, and in the step of printing the middle frame, two of the print heads are used to synchronously print the first spill prevention wall and the second spill prevention wall.

[0004] Therefore, there is an urgent need to provide a technical solution to solve the technical problem that the prior art uses a single needle to print back and forth multiple times, resulting in low efficiency. Summary of the Invention

[0005] The main object of the present invention is to provide a method, device, equipment and storage medium for printing a barrier wall of a display device based on multiple print heads, so as to solve the technical problem that the prior art uses a single needle to print back and forth repeatedly, resulting in low efficiency.

[0006] In the first aspect, the present invention provides a method for printing a barrier wall of a display device based on multiple print heads. The multiple print heads at least include one print head that is independently adjustable in the X and Y directions. The printing method includes:

[0007] Confirm the barrier wall printing path; control the multiple print heads to perform stacked printing along the same path at different Z-axis heights, and control the printing start points and end points of each print head to be the same.

[0008] Further, the barrier wall printing path includes a bending part and a non-bending part;

[0009] The printing method for the bending part includes: controlling the printing path of the print head that is independently adjustable in the X and Y directions to be the same as that of other print heads, so that each print head performs stacked printing of the bending part along the same path at different Z-axis heights;

[0010] The printing method for the non-bending part includes: controlling the multiple print heads to be the same in the X or Y direction and performing stacked printing of the non-bending part along the same path at different Z-axis heights along the arrangement direction of the print heads.

[0011] Further, the controlling the multiple print heads to perform stacked printing along the same path at different Z-axis heights includes:

[0012] Adjust the heights of each print head in the Z-axis direction so that the height difference between each print head is not less than the height of each layer of printing material, and on this basis, control the multiple print heads to perform stacked printing along the same path.

[0013] Further, the controlling the printing start points and end points of each print head to be the same includes:

[0014] According to the printing speed and the position distance between each print head, set the order of glue ejection of the multiple print heads successively, so that the printing start points and end points of each print head are the same in the X and Y directions.

[0015] Further, the multiple print heads are fixed on the same print shaft.

[0016] Further, the printing method includes but is not limited to direct writing printing, piezoelectric valve printing, impact needle valve printing, inkjet printing, etc.; the printing materials of the multiple print heads can be controlled to be the same or different according to product requirements.

[0017] In the second aspect, the present invention provides a device for printing a barrier wall of a display device based on multiple print heads. The multiple print heads at least include one print head that is independently adjustable in the X and Y directions. The device includes:

[0018] A path import module for confirming the printing path of the retaining wall;

[0019] A multi-printhead motion control module for controlling the multi-printheads to perform stacked printing along the same path at different Z-axis heights, and controlling the same printing start and end points for each printhead.

[0020] Further, the display device includes a display module and a middle frame, and the middle frame includes a retaining wall and a filling portion.

[0021] Further, the retaining wall includes a first retaining wall and a second retaining wall. The first retaining wall is disposed at the outer edge of the middle frame, the second retaining wall is disposed at the inner edge of the middle frame, and the filling portion is disposed between the first retaining wall and the second retaining wall.

[0022] In a third aspect, the present invention provides a computer device, including: a memory and a processor, which are communicatively connected to each other.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The printing efficiency is significantly improved; the present invention uses a multi-needle printing module containing printheads independently adjustable in the X and Y directions as the printing device. On this basis, according to the determined printing path of the retaining wall, by controlling the multi-printheads in the printing module to perform stacked printing along the same path at different Z-axis heights, and controlling the same printing start and end points for each printhead, the retaining wall can be printed at one time at a certain height, without the need for a single needle to print back and forth repeatedly.

[0026] (2) It is suitable for printing the middle frame containing curved parts; since the existing middle frame structure usually does not only contain straight-edge retaining walls but often contains curved parts, when using the existing multi-needle module to print the curved parts of the middle frame along the same path, the phenomenon of misalignment of the printing lines between the upper and lower layers will inevitably occur. Therefore, the existing multi-needle module is generally only used for printing different paths at the same time. The present invention controls the printing path of the printhead independently adjustable in the X and Y directions to be consistent with that of other printheads, thereby achieving a breakthrough in the stacked printing of the curved parts of the retaining wall of the display device by multiple printheads along the same path.

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] As described in the background art section of the present invention, in the prior art, usually a single needle is used to perform repeated multi-layer printing back and forth on the surface of the substrate to print the barrier ribs or dams of the display device, resulting in a problem of low printing efficiency; or a multi-needle module is used for printing the barrier ribs, but the printing paths corresponding to each needle are different. In this case, essentially, it is still equivalent to using a single needle to print the barrier ribs of the same path, and each printing needle in the multi-needle module still needs to use the method of repeated multi-layer printing back and forth to print the barrier ribs, and the printing efficiency is still limited.

[0040] The present invention provides a printing method for the barrier ribs of a display device based on multiple print heads. The multiple print heads at least include one print head independently adjustable in the X and Y directions. The printing method includes:

[0041] Confirm the printing path of the barrier ribs;

[0042] Control the multiple print heads to perform multi-layer printing along the same path (i.e., the above-mentioned confirmed printing path of the barrier ribs) at different Z-axis heights, and control the printing start points and end points of each print head to be the same.

[0043] In some specific embodiments, the printing path of the barrier ribs includes a curved portion and a non-curved portion;

[0044] The printing method for the curved portion includes: controlling the printing path of the print head independently adjustable in the X and Y directions to be the same as that of other print heads, so that each print head performs multi-layer printing of the curved portion along the same path at different Z-axis heights;

[0045] The printing method for the non-curved portion includes: controlling the multiple print heads to be the same in the X or Y direction and performing multi-layer printing of the non-curved portion along the same path at different Z-axis heights along the arrangement direction of the print heads;

[0046] The above technical means further solve the problem that the printed lines are prone to upper and lower layer misalignment when the existing multi-needle module is used to print the curved portion of the barrier ribs of the display device.

[0047] In some specific embodiments, the control of the multiple print heads to perform multi-layer printing along the same path at different Z-axis heights includes:

[0048] Adjust the height of each print head in the Z-axis direction so that the height difference between the print heads is not less than the height of each layer of printing material. On this basis, control the multi-print heads to perform laminated printing along the same path. For example, if the target retaining wall height is 1200 μm, select a print head with a discharge diameter of 400 μm, the printing line height is 300 μm, and use 4 print heads to perform laminated printing simultaneously (at least including 3 print heads that are independently adjustable in the X and Y directions), and a retaining wall with the target height can be printed at one time.

[0049] In some specific embodiments, the number of print heads can be appropriately adjusted according to the height of the retaining wall required for the target product. Specifically, assuming that N print heads are selected and fixed on the first printing axis according to the height of the retaining wall required for the target product, at least N - 1 of them are print heads that are independently adjustable in the X and Y directions.

[0050] In some specific embodiments, the control that the printing start points and end points of each print head are the same includes:

[0051] According to the printing speed and the position distance between each print head, set the order of the multi-print heads to discharge glue successively, so that the printing start points and end points of each print head are the same in the X and Y directions, and the printed retaining walls form a complete closed figure.

[0052] In some specific embodiments, the multi-print heads are fixed on the same printing axis, as Figure 4 shown, the needle valve 3 is fixed on the X-direction moving guide rail 4 and the Y-direction moving guide rail 5 on the gantry and can be moved in real time according to the control system. One of the print heads can be fixed to follow the movement of the printing axis without being independently adjustable in the X and Y directions. Each print head is independently adjustable in the Z direction.

[0053] In some specific embodiments, the multi-print heads at least include one print head that is independently adjustable in the X and Y directions. The device includes:

[0054] A path import module for confirming the retaining wall printing path;

[0055] A multi-print head motion control module for controlling the multi-print heads to perform laminated printing along the same path at different Z-axis heights, and controlling the printing start points and end points of each print head to be the same.

[0056] In some specific embodiments, the display device includes a display module and a middle frame, and the middle frame includes a retaining wall and a filling part.

[0057] In some specific embodiments, the retaining wall includes a first retaining wall and a second retaining wall. The first retaining wall is arranged on the outer edge of the middle frame, the second retaining wall is arranged on the inner edge of the middle frame, and the filling part is arranged between the first retaining wall and the second retaining wall. The first retaining wall and the second retaining wall are printed separately in sequence, and either the first retaining wall can be printed first or the second retaining wall can be printed first.

[0058] In some specific embodiments, the number of the multiple print heads can be appropriately adjusted according to the height of the target retaining wall, and preferably three or more print heads are used.

[0059] Embodiment 1

[0060] Taking the Figure 1 product structure shown as an example, the middle frame structure includes a retaining wall and a filling part. The retaining wall includes a first retaining wall 1 and a second retaining wall 2. The first retaining wall 1 is arranged at the outer edge of the middle frame, the second retaining wall 2 is arranged at the inner edge of the middle frame, and the filling part is arranged between the first retaining wall 1 and the second retaining wall 2.

[0061] The printing method is as follows:

[0062] (1) Select appropriate UV glue A (viscosity 1000000 cps) and UV glue B (viscosity 2000 cps) according to the size of the resin middle frame to be printed (height: 1.5 mm; width 5 mm); after configuration, load them into two 30 cc material tubes respectively and install them on a 3D printing device (in this embodiment, direct writing ceramic needle printing is taken as an example); the 3D printing device includes: a first printing shaft and a second printing shaft. The first printing shaft is used to fix a three-needle system (as Figure 2 shown, the middle print head is fixed to move along with the first printing shaft, and the other two print heads are independently adjustable in the X and Y directions), and the second printing shaft is used to fix a single-needle system for filling the filling part;

[0063] (2) Prepare a ceramic printing needle with an inner diameter of 100 μm and install it on the three-needle system of the first printing shaft, and calibrate the initial relative relationship between the three needles; prepare a ceramic printing needle with an inner diameter of 200 μm and install it on the single-needle system of the second printing shaft;

[0064] (3) Import the printing path and parameters required for the retaining wall and calibrate the relative relationship between the positioning camera, the height measuring sensor and the ceramic needle;

[0065] (4) Place the substrate to be printed on the suction cup with adsorption function of the 3D printing device and adsorb it, and then use the vision system on the device to perform edge grabbing and positioning on the substrate;

[0066] (5) Set the relevant printing parameters. The three needles on the first printing shaft are arranged front and back, the Z-direction height is adjusted to the height between printing layers, and the order of glue output between the three needles is set so that the printing start points and end points of each print head are the same in the X and Y directions (as Figure 3 shown);

[0067] (6) The printing device first uses the three-needle system on the first printing shaft to print the first and second retaining walls in sequence with UV glue A according to the preset printing parameters, and then the single-needle printing system uses UV glue B to print the intermediate filling part;

[0068] (7) Finally, the UV curing lamp on the device is used to cure the printed product to obtain the required middle frame structure.

[0069] For the physical diagram after printing, please refer to Figure 5 , from which it can be seen that there is no obvious upper and lower layer misalignment in the bending part of the printed product, and the coincidence degree of the printed lines of each layer after laminated printing is relatively good.

[0079] Comparative Example

[0080] This comparative example provides a method for laminated printing using a conventional multi-needle module. The printing process is the same as that in Embodiment 1, except that the three printing heads in the multi-needle module used in this comparative example are all fixed on the first printing axis and can only move synchronously following the first printing axis.

[0081] See the physical diagram after printing in Figure 6 , it can be seen from the figure that there is an obvious upper and lower layer misalignment in the bending part of its printed product. Refer to Figure 7 According to the printing path shown in the schematic diagram, when using a conventional multi-needle module for laminated printing, since there is a certain distance between the three print heads and they all move synchronously following the first printing axis, it will inevitably cause the upper and lower layer misalignment of the printing lines when printing the bending part of the middle frame, affecting the quality of the printed product.

[0082] It can be seen from the comparison between Example 1 and the comparative example that even when using a printing device with coaxial multi-print heads for the middle frame printing in the prior art, when printing the bending part of the middle frame, the phenomenon of upper and lower layer misalignment of the printing lines will still inevitably occur. Therefore, it is generally not thought of using coaxial multi-print heads for laminated printing along the same path. In the art, multi-print heads are often used to print different paths, but in essence, each print head still corresponds to printing a single path, and there is still the problem of repeated printing back and forth many times.

[0083] Thus, the present invention uses a multi-needle printing module containing print heads independently adjustable in the X and Y directions as the printing device. On this basis, according to the determined printing path of the retaining wall, by controlling the multi-print heads in the printing module to perform laminated printing along the same path at different Z-axis heights, and controlling the printing start points and end points of each print head to be the same, the retaining wall can be printed at one time at a certain height, without the need for a single needle to print back and forth many times, greatly improving the printing efficiency; in addition, since the existing middle frame structure usually does not only contain straight-edge retaining walls but often includes bending parts, when using the existing multi-needle module to print the bending part of the middle frame along the same path, the phenomenon of upper and lower layer misalignment of the printing lines will inevitably occur. Therefore, the existing multi-needle modules are generally only used for printing different paths simultaneously; the present invention controls the printing path of its print heads to be consistent with that of other print heads by adjusting the print heads independently adjustable in the X and Y directions, thus breaking through and realizing the laminated printing of the bending part of the retaining wall of the display device by multiple print heads along the same path, effectively avoiding the phenomenon of upper and lower layer misalignment of the printing lines during laminated printing.

[0084] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
