Printing electronics is an emerging technology that applies traditional printing (or coating) processes to the manufacture of electronic components and products.

However, the melting points of the metal components of the conductor paste are high, and after sintering, the conductive phase is still in particle contact, so that the contact resistance is high. The low-melting-point simple substance metal or alloy has low melting point and high conductivity, is in a liquid state at normal temperature and has better fluidity. The conductive ink made of the low-melting-point metal can replace electronic paste and is widely applied to the printing electronic industry.
Since the low-melting-point metal has extremely high fluidity and surface tension in a liquid state and cannot well meet the requirement for adhesion to the printing roller, the low-melting-point metal is generally modified into more viscous slurry by adding conductive particles into the low-melting-point metal, so that the fluidity and surface tension of the low-melting-point metal are reduced, and the adhesion force is increased. The traditional inking structure generally adopts an ink fountain matching roller to roll an ink transferring and distributing structure to realize uniform upper roller of the ink, but for the modified low-melting-point metal ink, the gap pressure is set to be a serious problem, the gap pressure is set to be large, the low-melting-point metal in the low-melting-point metal ink and the added conductive particles are easy to phase-split, the prior modification effect is failed, a large number of conductive particles can be accumulated in the gap, and the gap pressure is set to be small, so that the problems of leakage of the ink from the gap and poor ink distributing effect can be caused, namely the ink supplying structure in the prior art is extremely difficult to meet the requirement of stable inking of the low-melting-point metal ink.

Embodiments of the invention may be referred to herein, individually or collectively, by the term "invention" merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed.
It should be noted that the technical features in the embodiments of the present invention may be combined with each other without conflict.
The embodiment of the invention discloses a plane printing ink supply structure, as shown in fig. 1 and fig. 2, fig. 1 is a schematic structural side view of the plane printing ink supply structure in the embodiment of the invention; fig. 2 is a schematic top view of a planar printing ink supply structure according to an embodiment of the present invention. The plane printing ink supply structure comprises: the ink supply device comprises an ink supply working surface 10, an ink storage cavity 20, a driving part 30 and a brushing part 40. The ink storage cavity 20 is used for storing ink 50, and is a variable cavity volume structure, and is disposed on one side of the ink supply working surface 10, and the ink supply port 21 thereof is exposed on the surface of the other side of the ink supply working surface 10, so that the ink 50 flowing out through the ink supply port 21 of the ink storage cavity 20 can reach the surface of the other side of the ink supply working surface 10. The driving member 30 is engaged with the ink storage cavity 20, and by controlling the volume change of the ink storage cavity 20, the ink storage cavity 20 is squeezed, so that the cavity structure is compressed, and the ink 50 is squeezed out of the ink storage cavity 20 onto the surface of the ink supply working surface 10. The brush member 40 is disposed on the other side of the ink supplying working surface 10, and when the ink supplying process is required, the brush member 40 obtains the ink 50 squeezed out of the ink supplying working surface 10 by contacting and moving relative to the surface of the ink supplying working surface 10.
In the embodiment of the invention, the ink supply structure is designed into a structure extruded on a plane, so that the problems of phase splitting, leakage and the like of high-viscosity and easily-phase-split ink are avoided, and the ink supply structure has a simple structure, is easy to process and implement and is easy to clean the ink supply surface.
The ink supply working surface 10 of the embodiment of the present invention is a rigid structure, and may be made of a rigid material, or an elastic layer is compounded on the surface of the rigid structure, so as to facilitate the contact of the brush member 40 with the ink. Specifically, when the inking surface 10 is in contact with the brushing member 40, the brushing member 40 can achieve sufficient contact with the ink 50 under the application of an appropriate force, thereby carrying away the ink 50 on the inking surface 10. Furthermore, the brushing part 40 can be made of a surface material which is easy to adhere to the ink 50, and the ink supplying working surface 10 is made of a surface material which is not adhered to the ink 50 or has poor adhesion to the ink 50, so that the ink 50 is further ensured to be separated from the ink supplying working surface 10 and adhere to the brushing part 40.
The material that is adhered or not adhered to the ink in this embodiment may be selected according to the specific surface properties of the ink 50, for example, for the low melting point metal ink mixed with metal particles, the surface of the ink supply working surface 10 may be made of stainless steel, teflon, plain glass, etc., and the brush member 40 may be made of nitrile rubber, polyurethane, etc. Those skilled in the art will appreciate that there are many other surface materials that can meet the above needs in the art and the present invention is not limited thereto.
The brush coating component 40 in the embodiment of the present invention may be selected from a roller structure shown in fig. 1, a bristle structure shown in fig. 3, and the like; wherein the roller body structure can be a roller body with a smooth surface or an anilox roller with specific textures. Further, as for the brush member 40 of the roller structure, it may be a single roller structure such as an ink supply roller, a coating roller, an ink form roller, etc.; preferably, only one coating roller can be directly selected from the brushing part 40, the coating roller can directly print the printing substrate after inking, and other processes such as ink transfer, ink distribution and the like are not needed in the middle, and other functional roller bodies such as an ink distribution roller, an ink oscillating roller, an ink transfer roller and the like are not needed, so that the complexity of the equipment structure is simplified, the equipment cost is reduced, and the inapplicability of the roller-to-roller structure to high-viscosity and easily-phase-separated ink is avoided.
The cavity volume variable structure of the ink storage cavity 20 in the embodiment of the present invention may specifically adopt a flexible cavity structure or a piston cavity structure; in which a flexible cavity structure, such as an ink bag structure, stores ink 50, and the ink bag can deform under the external force, so that the ink 50 is extruded from the ink supply port 21. The piston chamber structure means that part of the chamber wall of the chamber is a dynamic chamber formed by a piston body member, and when the piston body moves towards the inside of the chamber, the volume inside the chamber is reduced, so that the ink 50 is extruded from the ink supply port 21.
As shown in fig. 4, the driving part 30 in the embodiment of the present invention mainly controls the volume change of the ink reservoir 20 by mechanical action such as motor-driven, hydraulic-driven, and pneumatic-driven squeezing actions, and squeezing the ink reservoir 20 can apply horizontal and/or vertical squeezing forces to the ink reservoir 20 through a corresponding linkage structure; the driving member 30 may apply pressing force to the ink storage chamber 20 in any other direction through other structures, which is not particularly limited. Preferably, the driving part 30 in the embodiment of the present invention includes: the power source 31 is a motor displacement driving mechanism, a hydraulic driving mechanism, and an air pressure control mechanism, and the power source 31 directly acts on the squeezing member 32, and the squeezing member 32 acts on the ink storage chamber 20. In the case that the ink storage chamber 20 is a piston chamber structure, the pressing member 32 may be a piston body constituting the chamber. Fig. 4 shows a schematic diagram of the power source 31 constituted by an air pressure control mechanism (e.g., an air pump).
Alternatively, the number of the ink supply ports 21 on the surface of the ink supply working surface 10 in the embodiment of the present invention is plural, and the ports are spaced on the surface of the ink supply working surface 10, respectively; in the case of using a roller structure (e.g., an applicator roller) for the applying member 40, the working surface 10 between each of the ink supply ports 21 is in contact with the applicator roller with a pressure, which satisfies the ink distribution of the ink on the applicator roller. Further, the plurality of ink supply ports 21 in this embodiment may be distributed on the surface of the ink supply working surface 10 at equal intervals, so that during the relative movement between the brushing member 40 and the ink supply working surface 10, each ink supply port 21 contacts with a different area of the brushing member 40, thereby preventing a large amount of ink from adhering to the same area and ensuring the ink distribution effect of the ink supply working surface 10 on the ink on the coating roller. Wherein, each ink supply port 21 is a hole array structure along the axial direction of the coating roller; furthermore, the hole array structure can also be a porous structure, so that ink can be distributed and applied between the ink and the coating roller as much as possible through multiple points, and the uniformity of the ink application is ensured.
Further, in the case of selecting a coating roller as the brushing member 40, the length of the inking surface 10 may be the same as the length of the circumferential surface of the coating roller, and the ink supply ports 21 are uniformly distributed along the moving direction of the coating roller on the inking surface 10, so that the inking and leveling effects of the coating roller can be satisfied by one movement of the coating roller on the inking surface 10.
Alternatively, as shown in fig. 5, in the case where the number of ink supply ports 21 on the surface of the ink supply working surface 10 is plural, the number of ink storage chambers 20 is also plural, and each ink storage chamber 20 has at least one ink supply port 21; the driving part 30 may control the ink squeeze-out amount of each ink reservoir 20 separately, or control the ink reservoirs 20 to maintain an equal ink squeeze-out amount at the same time. The driving part 30 can control the ink displacement amount of each ink storage cavity 20, and can control the ink displacement amount of each ink storage cavity 20 separately by adopting an independent driving structure for each ink storage cavity 20. The power source 31 shown in fig. 5 may be a hydraulic control mechanism (e.g., a hydraulic pump).
In other embodiments, as shown in fig. 6, for the case that the driving member 30 controls the ink storage chamber 20 to maintain the uniform ink squeezing amount at the same time, the driving member 30 may adopt a structure of a plurality of squeezing members 32 driven by one power source 31 at the same time (for example, through a linkage 33), that is, the plurality of squeezing members 32 are in a linkage structure, so as to ensure that each squeezing member 32 is driven by the power source 31 to act on each ink storage chamber with uniform external force, thereby achieving the purpose of controlling the ink storage chamber to maintain the uniform ink squeezing amount at the same time. The power source 31 in this embodiment may be a drive motor.
Optionally, the end of the ink storage chamber 20 near the ink supply port 21 in the embodiment of the present invention is a throat structure for converging and guiding the ink.
Preferably, as shown in fig. 7 and 8, the planar printing ink supply structure in the embodiment of the present invention may further include: an ink supply table 100; the ink supply table 100 has an ink supply working surface 10; the ink storage chamber 20 is provided inside the ink supply table 100, and the driving part 30 is mounted on the ink supply table 100. Specifically, the ink supply table 100 is a horizontally placed structure, the upper surface of which serves as the ink supply working surface 10, the ink supply table 100 has a plurality of through holes 101 in the vertical direction, a piston body (such as the above-mentioned pressing member 32) is fitted at the lower part of each through hole 101, the lower part of the through hole 101 is sealed by the piston body, the upper port of the through hole serves as the ink supply port 21 exposed on the ink supply working surface 10, that is, an ink storage chamber 20 is formed by the through hole, the piston body and the ink supply port 21 of the ink supply table; a driving motor (such as the power source 31 described above) is mounted below the ink supply table 100, connected to each piston body through a link mechanism (such as the link 33 described above), and is uniformly controlled. Further, a sealing ring is arranged at the matching position of the piston body and the through hole 101, so that the sealing effect of the printing ink is further guaranteed.
The plane printing ink supply structure in the embodiment of the invention can meet the printing use of high-viscosity and easily-phase-separable ink, but not only can be used for the ink, but also can meet the use of low-viscosity ink. Furthermore, when the ink is high-viscosity ink, the fluidity of the ink is poor, the ink supply working surface 10 can be obliquely arranged according to the specific fluidity of the ink, and the ink supply working surface 10 can even be vertically or horizontally arranged in an inverted manner under the condition of high viscosity.
The embodiment of the invention provides a plane printing ink supply structure, which extrudes ink in an ink storage cavity to an ink supply working surface in an extrusion mode through a driving part, and then takes away the extruded ink through the movement of a brushing part on the ink supply working surface.
