Description

Technical Field

[0001] This invention relates to the field of screen printing, specifically to a nickel alloy screen for printing and its manufacturing method. Background Technology

[0002] Nickel and nickel alloys are important strategic materials with excellent properties, such as excellent corrosion resistance, high thermal strength, superior processing performance, and special electromagnetic and shape memory properties. Processed nickel alloys are high-value-added products and are among the most researched metals internationally. Nickel alloys can be further classified according to their applications into high-temperature alloys, corrosion-resistant alloys, shape memory alloys, wear-resistant alloys, and precision alloys. Nickel alloys possess excellent corrosion resistance, high-temperature strength, and oxidation resistance. Some special alloys also exhibit shape memory and excellent electromagnetic properties, making them widely used in military, aerospace, marine, electronics, petrochemical, and new energy industries.

[0003] Traditionally, the wire mesh industry has used steel wire woven mesh to make screens. In recent years, due to the high demand for products and the improvement of silicon wafer conversion efficiency, the mainstream high mesh count steel wire mesh (480-11 / 520-11) can no longer meet the needs of the current process. Moreover, all high mesh count mesh in China is completely dependent on imports. This is because the specifications are limited, and the subsequent procurement is already stretched thin due to foreign sanctions. Summary of the Invention

[0004] To address the problems in existing technologies, this invention provides a nickel alloy wire mesh for printing and its manufacturing method. It is manufactured through a micro-electroforming integrated molding design, utilizing the cathode deposition phenomenon in the electrochemical process for molding, resulting in extremely high replication and dimensional accuracy. It can replace the use of traditional mesh, and due to its flexible design, various solutions have been designed to suit different application scenarios.

[0005] The technical solution adopted by this invention to solve its technical problem is: a nickel alloy wire mesh for printing and its manufacturing method, comprising the following steps:

[0006] Step 1: Select a nickel alloy plate as the prototype mold;

[0007] Step 2: Clean the surface of the original mold selected in Step 1 to remove dirt and oil.

[0008] Step 3: Using chemical cathodic deposition, the original mold is used as the material. Electroforming solution is added, and the nickel mesh is integrally formed through electroforming.

[0009] Step 4: Demold the electroformed nickel mesh obtained after step 3 to obtain a nickel alloy mesh;

[0010] Step 5: After demolding in Step 4, the nickel alloy mesh obtained is hot-melted and laminated with PE film using a hot-melt machine;

[0011] Step Six: Adjust the straightness of the nickel alloy mesh after Step Five using a top frame machine;

[0012] Step 7: The nickel alloy mesh processed in Step 6 is continuously tensioned by the top frame machine until the tension meets the requirements. Then, the adhesive is applied and cured to obtain the nickel alloy mesh plate.

[0013] Step 8: Apply PI film to the surface of the nickel alloy screen after the treatment in Step 7, so that the PI film adheres tightly to the surface of the nickel alloy screen.

[0014] Step 9: Place the nickel alloy screen printing plate, after the hot-stamped film has stabilized, on a fixed platform, and use a laser scribing machine to form lines of a set width on the PI film to obtain the finished screen printing plate;

[0015] Step 10: The finished wire mesh after the above steps is inspected for dimensions, surface defects, and tension values. This invention utilizes a fusion of nickel, chromium, and other trace elements to achieve the same effect as traditional wire mesh. In terms of strength, deformation, and resilience, it completely replaces traditional wire mesh, and its shape can be freely set, allowing for narrower wire diameters of 10µm, 9µm, 8µm, and even narrower diameters of 7µm, 6µm, and 5µm. The nickel alloy can be manufactured using existing plate-making processes. Furthermore, because the nickel alloy wire mesh produced by this invention is integrally formed, unlike traditional mesh which is woven from a single sheet and then cut, the cutting step is eliminated. In PI plate-making, the wire drawing process is eliminated, significantly improving the manufacturing cycle of the wire mesh and saving on wire drawing equipment costs.

[0016] Furthermore, the nickel alloy plate mentioned in step one is composed of nickel content less than 99.6%, cobalt content less than 0.06%, copper content less than 0.1%, silicon content less than 0.2%, manganese content less than 0.2%, carbon content less than 0.1%, magnesium content less than 0.1%, sulfur content less than 0.005%, iron content less than 0.1%, and other impurities totaling less than 0.5%.

[0017] Furthermore, the electroforming solution in step three is a mixture of nickel sulfate and cobalt sulfate.

[0018] Furthermore, in step five, the operating temperature of the hot melt machine is 165-190 degrees Celsius. The hot melt time is 80-110 seconds. After hot melting, the edges of the nickel alloy mesh must be neat, without burrs or whitening.

[0019] Furthermore, in step six, by adjusting the top frame machine, the straightness of the nickel alloy mesh is always kept between 100-125um. After the top frame is completed, the surface of the mesh must not have wrinkles, dents, holes, or scratches.

[0020] Furthermore, in step eight, the working temperature of the heat press is 200-240℃, the heat pressing time is 1650-1800 seconds, and there should be no bubbles, wrinkles, or peeling after heat pressing.

[0021] Furthermore, in step nine, the power of the laser marking machine is controlled between 0.4 and 0.7 watts.

[0022] Furthermore, in step nine, the line width error is required to be less than 1µm, and the harpoon width error is required to be less than 1µm.

[0023] Furthermore, in step ten, the film thickness error is required to be less than 1 μm, the tension error is less than 1 N, and the total PT length error is less than 15 μm.

[0024] Furthermore, the final product, the nickel alloy wire mesh, has a wire diameter of 7-11 μm.

[0025] Therefore, the overall objective of this invention is to provide a nickel alloy wire mesh for printing, which uses nickel alloy material instead of traditional steel wire mesh for screen making, and a method for its manufacturing process. This solution reduces the drawbacks of existing solutions. More specifically, this invention aims to achieve all or part of the following objectives;

[0026] The primary objective of this invention is to propose a nickel alloy wire mesh for printing, which uses nickel alloy material to replace traditional steel wire mesh for screen making and its manufacturing method. This addresses the current shortage of high-mesh-count wire mesh production capacity and also lays a data foundation for the subsequent research and application of other metal wire meshes.

[0027] The second objective of this invention is to propose a high-performance, reliable, and economical method to solve the problem that flat mesh knots can affect the passage of slurry and the leveling after ink application, and even cause grid breakage, affecting the conductivity of the lines and resulting in low cell conversion efficiency.

[0028] Furthermore, this invention also has the following advantages: production capacity is not limited, and the finished product specifications can meet the needs of all manufacturers in the market; different yarn thicknesses, wire diameters, and openings can be provided according to customer needs, offering a high degree of flexibility and completely breaking away from the fixed design of traditional wire mesh squares; and because it is integrally molded, it eliminates the woven knots of traditional wire mesh, which is more conducive to the ink penetration of the paste on the grid lines of the finished screen; the price per piece is lower than that of traditional wire mesh, making it more cost-effective in terms of screen cost; it has very high plasticity and can be combined with different metals to enhance its strength, toughness, and stability, showing broad prospects.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figures 1-2 As shown, the present invention discloses a nickel alloy wire mesh for printing and its manufacturing method, comprising the following steps:

[0038] Step 1: Select a nickel alloy plate with a nickel content of 99.5%-99.6%, a cobalt content of 0.03-0.05%, a silicon content of less than 0.1%, and a total of other impurities of less than 0.5% as the prototype.

[0039] Step 2: Use a phosphorus-free corrosion inhibitor to immerse the original mold in water to remove oil, and then spray it with warm water to remove surface dirt and residual oil film from storage.

[0040] Step 3: Using the original mold as raw material, add a mixed reagent made of nickel sulfate and cobalt sulfate, and electroform in the equidistant rectangular mesh mold using chemical cathodic deposition to obtain a rectangular array-distributed integrated nickel alloy mesh.

[0041] Step 4: Demold and clean the nickel alloy mesh, and check the surface for any obvious defects;

[0042] Step 5: Cover the surface of the cleaned and demolded nickel alloy mesh with a PE film of 0.05-0.10mm thickness, then place it on a hot melt machine, set the temperature to 165 degrees Celsius, and press for 10 seconds to complete the pre-melting. Then perform a visual inspection to ensure it meets the relevant requirements; then place it on the hot melt machine table, set the temperature to 165 degrees Celsius, and press for 70 seconds to complete the fusion of the PE film and the nickel alloy mesh.

[0043] Step Six: After the nickel alloy mesh has been hot-melted in Step Five, let it stand to stabilize. Then place it on the top frame machine to adjust its straightness.

[0044] Step 7: The nickel alloy mesh is placed on the top frame machine, which continuously provides tension to the nickel alloy mesh until it meets the tension requirement of 35-40N. Then, use a scraper to evenly apply photosensitive emulsion to the mesh. During the operation, the scraper blade should be smooth, and the photosensitive emulsion should be of uniform and even thickness. Then, place it in the drying device and set the temperature to less than 50 degrees Celsius to complete the curing.

[0045] Step 8: Place a PI film with a thickness of 1mil-5mil on the surface of the screen, then place it on the hot press table, set the temperature to 165-170 degrees, press for 5-10 seconds to complete the pre-pressing, and perform an appearance inspection until it meets the relevant requirements; then place it on the hot press table, set the temperature to 165 degrees, press for 90 seconds to complete the bonding of the PI film and the mesh.

[0046] Step 9: Place the screen after the heat-pressed film has been stabilized on a fixed platform, measure the height to determine the focal length of the laser cutting, and then set the processing parameters according to the selected processing drawing. Starting from the designated position, the laser will act on the PI film surface with a certain pulse.

[0047] Step 10: After processing in the above steps, inspect the finished screen for dimensions, surface defects, and tension values. The nickel alloy screen must have neat edges, free from burrs and whitening. The screen surface must be free from wrinkles, dents, holes, scratches, bubbles, and peeling. The nickel alloy screen obtained after these steps has a rectangular structure with negligible knots. This effectively improves the problem of flat knots affecting ink flow and leveling after ink application, which is common in traditional screens. Simultaneously, the resulting screen with a high opening area and small bridges possesses high strength and durability, ensuring that the printed graphics do not exhibit unevenness or inconsistent width.

[0048] Example 2

[0049] like Figure 3 As shown, the present invention discloses a nickel alloy wire mesh for printing and its manufacturing method, comprising the following steps:

[0050] Step 1: Select a nickel alloy plate with a nickel content of 99.6%, a cobalt content of 0.04-0.07%, a magnesium content of less than 0.05%, a sulfur content of less than 0.1%, a carbon content of less than 0.15%, and a total of other impurities of less than 0.2% as the prototype.

[0051] Step 2: Use a cleaning agent containing alkali and vinyl ether to immerse the original mold in water to remove oil, and then spray it with warm water to remove surface dirt and residual oil film from storage.

[0052] Step 3: Using the original mold as raw material, add a mixed reagent made of nickel sulfamate and boric acid, and electroform in the equidistant regular hexagonal screen mold using chemical cathodic deposition to obtain an integrated nickel alloy screen with hexagonal array distribution.

[0053] Step 4: Demold and clean the nickel alloy mesh, and check the surface for any obvious defects;

[0054] Step 5: Cover the surface of the cleaned and demolded nickel alloy mesh with a PE film of 0.05-0.10mm thickness, then place it on a hot melt machine, set the temperature to 170-180 degrees Celsius, and press for 10-15 seconds to complete the pre-melting. Then perform a visual inspection until it meets the relevant requirements; then place it on the hot melt machine table, set the temperature to 170-180 degrees Celsius, and press for 100 seconds to complete the fusion of the PE film and the nickel alloy mesh.

[0055] Step Six: After the nickel alloy mesh has been hot-melted in Step Five, let it stand to stabilize. Then place it on the top frame machine to adjust its straightness.

[0056] Step 7: The nickel alloy mesh is placed on the top frame machine, which continuously provides tension to the nickel alloy mesh until it meets the tension requirement of 30-40N. Then, use a scraper to evenly apply photosensitive emulsion to the mesh. During the operation, the scraper blade should be smooth, and the photosensitive emulsion should be of uniform and flat thickness. Then, place it in the drying device and set the temperature to less than 50 degrees Celsius to complete the curing.

[0057] Step 8: Place a PI film with a thickness of 2mil-5mil on the surface of the screen, then place it on the hot press table, set the temperature to 170-180 degrees, press for 10 seconds to complete the pre-pressing, and perform an appearance inspection until it meets the relevant requirements; then place it on the hot press table again, set the temperature to 170-180 degrees, press for 100 seconds to complete the bonding of the PI film and the mesh.

[0058] Step 9: Place the screen after the heat-pressed film has been stabilized on a fixed platform, measure the height to determine the focal length of the laser cutting, and then set the processing parameters according to the selected processing drawing. Starting from the designated position, the laser will act on the PI film surface with a certain pulse.

[0059] Step 10: After processing in the above steps, inspect the finished screen for dimensions, surface defects, and tension values. The nickel alloy mesh must have neat edges, free from burrs and whitening. The mesh surface must be free from wrinkles, dents, holes, scratches, bubbles, and peeling. The hexagonal nickel alloy mesh obtained after these steps has a smooth surface and a non-woven warp and weft structure, effectively improving the problem of flat mesh knots affecting ink flow and leveling after ink application in traditional screen printing. This greatly improves the uneven ink application problem during traditional printing screen printing. Simultaneously, the produced screen with a high opening area and small bridges possesses high strength and durability, ensuring that the printed graphics do not have uneven heights or widths. Furthermore, the regular hexagonal nickel alloy mesh exhibits very high stability and mechanical strength for different opening ratios, wire diameters, and wire shapes.

[0060] Example 3

[0061] like Figure 4 As shown, the present invention discloses a nickel alloy wire mesh for printing and its manufacturing method, comprising the following steps:

[0062] Step 1: Select a nickel alloy plate with a nickel content of 99.5%-99.7%, an iron content of 0.1%-0.15%, a silicon content of less than 0.1%, a chromium content of less than 0.05%, and a total of other impurities of less than 0.3% as the prototype.

[0063] Step 2: Use an alkaline cleaning agent to immerse the original mold in water to remove oil, and then spray it with warm water to remove surface dirt and residual oil film from storage.

[0064] Step 3: Using the original mold as raw material, add a mixed reagent made of nickel sulfate and nickel chloride, and electroform in the fabricated wall-type back fine mesh positioning mold using chemical cathodic deposition method to obtain a wall-type back fine integrated nickel alloy mesh.

[0065] Step 4: Demold and clean the nickel alloy mesh, and check the surface for any obvious defects;

[0066] Step 5: Cover the surface of the cleaned and demolded nickel alloy mesh with a PE film of 0.010-0.15mm thickness, then place it on a hot melt machine, set the temperature to 180 degrees Celsius, and press for 5-10 seconds to complete the pre-melting. Then perform a visual inspection to ensure it meets the relevant requirements; then place it on the hot melt machine table, set the temperature to 180 degrees Celsius, and press for 110 seconds to complete the fusion of the PE film and the nickel alloy mesh.

[0067] Step Six: After the nickel alloy mesh has been hot-melted in Step Five, let it stand to stabilize. Then place it on the top frame machine to adjust its straightness.

[0068] Step 7: The nickel alloy mesh is on the top frame machine. The top frame machine continuously provides tension to the nickel alloy mesh until the tension requirement of 45±1N is met. Then, use a scraper to evenly apply photosensitive emulsion to the mesh. During the operation, the scraper blade should be smooth and the photosensitive emulsion should be of uniform thickness. Then, put it into the drying device and set the temperature to less than 50 degrees to complete the curing.

[0069] Step 8: Place a PI film with a thickness of 2mil-5mil on the surface of the screen, then place it on the hot press table, set the temperature to 175-180 degrees, press for 10 seconds to complete the pre-pressing, and perform an appearance inspection until it meets the relevant requirements; then place it on the hot press table, set the temperature to 180 degrees, press for 100 seconds to complete the bonding of the PI film and the mesh.

[0070] Step 9: Place the screen after the heat-pressed film has been stabilized on a fixed platform, measure the height to determine the focal length of the laser cutting, and then set the processing parameters according to the selected processing drawing. Starting from the designated position, the laser will act on the PI film surface with a certain pulse.

[0071] Step 10: After processing in the above steps, inspect the finished screen for dimensions, surface defects, and tension values. The nickel alloy screen must have neat edges, free from burrs and whitening. The screen surface must be free from wrinkles, dents, holes, scratches, bubbles, and peeling. The fine nickel alloy screen obtained after these steps has a wall-like alternating mesh structure, which effectively reduces the unit consumption during sizing, greatly improving screen life and printability. It is particularly suitable for ultra-fine wire mesh screens with wire diameters between 7-10 micrometers, effectively improving the strength and durability of ultra-fine wire mesh screens.

[0072] Example 4

[0073] like Figure 5 As shown, the present invention discloses a nickel alloy wire mesh for printing and its manufacturing method, comprising the following steps:

[0074] Step 1: Select a nickel alloy plate with a nickel content of 99.4%-99.9%, a cobalt content of 0.03-0.05%, a silicon content of less than 0.1%, and a total of other impurities of less than 0.2% as the prototype.

[0075] Step 2: Use a phosphorus-free corrosion inhibitor to immerse the original mold in water to remove oil, and then spray it with warm water to remove surface dirt and residual oil film from storage.

[0076] Step 3: Using the original mold as raw material, add a mixed reagent made of sulfate-chloride, and use chemical cathodic deposition to electroform a mold with a certain number of horizontal lines and a certain number of vertical lines to obtain a knotless, wire-drawing integrated nickel alloy mesh.

[0077] Step 4: Demold and clean the nickel alloy mesh, and check the surface for any obvious defects;

[0078] Step 5: Cover the surface of the nickel alloy mesh after demolding and cleaning with a PE film of a specified thickness, then place it on a hot melt machine, set the temperature to 165 degrees Celsius, and press for 10 seconds to complete the pre-melting. Then perform an appearance inspection until it meets the relevant requirements; then place it on the hot melt machine table, set the temperature to 165 degrees Celsius, and press for 70 seconds to complete the fusion of the PE film and the nickel alloy mesh.

[0079] Step Six: After the nickel alloy mesh has been hot-melted in Step Five, let it stand to stabilize. Then place it on the top frame machine to adjust its straightness.

[0080] Step 7: The nickel alloy mesh is placed on the top frame machine, which continuously provides tension to the nickel alloy mesh until it meets the tension requirement of 35-40N. Then, use a scraper to evenly apply photosensitive emulsion to the mesh. During the operation, the scraper blade should be smooth, and the photosensitive emulsion should be of uniform and even thickness. Then, place it in the drying device and set the temperature to less than 50 degrees Celsius to complete the curing.

[0081] Step 8: Place the PI film of the specified thickness on the screen surface, then place it on the hot press table, set the temperature to 165-170 degrees, press for 5-10 seconds to complete the pre-pressing, and perform an appearance inspection until it meets the relevant requirements; then place it on the hot press table, set the temperature to 165 degrees, press for 90 seconds to complete the bonding of the PI film and the mesh.

[0082] Step 9: Place the screen after the heat-pressed film has been stabilized on a fixed platform, measure the height to determine the focal length of the laser cutting, and then set the processing parameters according to the selected processing drawing. Starting from the designated position, the laser will act on the PI film surface with a certain pulse.

[0083] Step 10: After processing in the above steps, inspect the finished screen for dimensions, surface defects, and tension values. The nickel alloy screen must have neat edges, free from burrs and whitening. The screen surface must be free from wrinkles, dents, holes, scratches, bubbles, and peeling. The nickel alloy screen obtained after these steps has the structure of a traditional screen after wire drawing, effectively improving the flat mesh structure that affects ink flow and leveling after ink application. It also avoids the discontinuity of printed patterns common in conventional screens, thus improving printing quality and printing efficiency for solar cells. It ensures that the printed graphics will not have uneven heights or inconsistent widths.
