[0002] In the manufacturing process of printed circuit boards (PCBs), after etching the circuits and pads of the PCB board, the PCB board needs to be treated with solder mask. Among them, roll coating is a commonly used solder mask method, which is to evenly coat the liquid ink on the surface of the package substrate so that the ink thickness on both sides is consistent.
[0003] Special substrates require differentiated ink thickness on both sides, that is, the ink thickness on the joint surface and the welding surface is inconsistent, one side is thin and the other side is thick. The existing roller coating line design directly adjusts the amount of ink on the coating roller surface by adjusting the positive scraper pressure. That is, the larger the positive scraper pressure value, the greater the force of the positive scraper squeezing the coating roller, the less ink on the coating roller surface, and the thinner the ink thickness finally coated on the substrate surface. However, due to the limited effect of the positive scraper on the amount of ink on the coating roller surface of the two sides, it is impossible to accurately control the measured ink thickness. When the coating rollers on the two sides squeeze the substrate product together to transfer the ink on the coating roller surface to the surface of the substrate product, the two sides of the substrate can achieve ink differentiation. Therefore, how to achieve precise control of differentiated ink thickness is a technical difficulty that urgently needs to be solved in the industry. Summary of the invention

[0038] like Figure 1 As shown, an embodiment of the present invention provides an ink rolling processing equipment, which includes a first rolling coating structure 1 and a second rolling coating structure 2, wherein the first rolling coating structure 1 and the second rolling coating structure 2 are symmetrically arranged with the packaging substrate 3 as the axis, and are respectively located on the element interface and the welding surface of the packaging substrate 3, and both include a positive scraper (positive scraper 11 and positive scraper 21), an ink storage area (ink storage area 12 and ink storage area 22), a pre-coating roller (pre-coating roller 13 and pre-coating roller 23) and a coating roller (coating roller 14 and coating roller 24), wherein the ink storage area (ink storage area 12 and ink storage area 22) is located between the positive scraper (positive scraper 11 and positive scraper 21) and the pre-coating roller (pre-coating roller 13 and pre-coating roller 23), when the positive scraper (positive scraper 11 and positive scraper 21) and the pre-coating roller (pre-coating roller When the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) contacts, the ink in the ink storage area (ink storage area 12 and ink storage area 22) is printed onto the surface of the pre-coating roller (pre-coating roller 13 and pre-coating roller 23); when the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) contacts the coating roller (coating roller 14 and coating roller 24), the ink of the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) is printed onto the surface of the coating roller (coating roller 14 and coating roller 24); the coating roller (coating roller 14 and coating roller 24) is rotated to transfer the ink on the surface of the coating roller (coating roller 14 and coating roller 24) to the element interface and welding surface of the packaging substrate 3, thereby solving the problem that the prior art cannot achieve precise control of differentiated ink thickness, so that the ink rolling efficiency is high and the rolling process is stable.
[0039] In the embodiments of the present disclosure, Figure 2-4As shown, during the ink rolling process, the package substrate 3 to be processed is located between the first rolling structure 1 and the second rolling structure 2 in the ink rolling process equipment. When the positive scrapers (positive scrapers 11 and positive scrapers 21) and the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) of the two sides in the ink rolling process equipment are in contact in advance, the distance between the positive scrapers (positive scrapers 11 and positive scrapers 21) and the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) is adjusted so that the ink in the ink storage areas (ink storage areas 12 and ink storage areas 22) is printed onto the surfaces of the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23), thereby adjusting the amount of ink on the surfaces of the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23), and then the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) and the coating rollers (coating rollers 14 and The coating roller 24 is in contact with the pre-coating roller (pre-coating roller 13 and pre-coating roller 23), and the distance between the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) and the coating roller (coating roller 14 and coating roller 24) is adjusted so that the ink of the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) is printed on the surface of the coating roller (coating roller 14 and coating roller 24), thereby adjusting the amount of ink on the surface of the coating roller (coating roller 14 and coating roller 24), and finally the ink on the surface of the coating roller (coating roller 14 and coating roller 24) is transferred to the element interface and welding surface of the packaging substrate 3 by controlling the rotation of the coating roller (coating roller 14 and coating roller 24), wherein the two surfaces are surface A and surface B respectively, and the structural design is reasonable and the rolling process is stable, thereby realizing the precise control of the ink differentiation of the two surfaces of the packaging substrate, improving the product yield and reducing the scrapping cost of defective products.
[0040] In one embodiment, a plurality of coating teeth are evenly arranged on the outer circumference of the pre-coating roller and the coating roller, and grooves capable of accommodating ink are formed between adjacent coating teeth.
[0041] In the embodiments of the present disclosure, Figure 5As shown, the structures of the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) and the coating rollers (coating rollers 14 and coating rollers 24) are both groove-shaped structures. During the rotation of the rollers, the ink is transferred to the surface of the packaging substrate 3 through the groove-shaped structure for uniform coating, so that the amount of ink coated on the board surface is controlled by controlling the ink carrying amount of the rollers, and the outer peripheral surfaces of the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) and the coating rollers (coating rollers 14 and coating rollers 24) are evenly provided with a plurality of coating teeth, and the gaps between adjacent coating teeth are A groove capable of accommodating ink is formed. By setting this structure so that the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) and the coating roller (coating roller 14 and coating roller 24) can rotate, compared with the traditional structure, the ink can be reasonably stored so that the pre-coating roller (pre-coating roller 13 and pre-coating roller 23) and the coating roller (coating roller 14 and coating roller 24) can achieve a stable ink volume effect, thereby applying the ink to the surface of the packaging substrate and evenly coating it, and the thickness of the ink after coating is uniform and different.
[0042] In one embodiment, the pre-coating roller and the coating roller rotate relative to each other.
[0043] In the embodiment of the present disclosure, the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) and the coating rollers (coating rollers 14 and coating rollers 24) rotate relative to each other so that the ink on the surface of the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) is printed onto the surface of the coating rollers (coating rollers 14 and coating rollers 24), thereby ensuring that the ink on the surface of the subsequent coating rollers (coating rollers 14 and coating rollers 24) can be printed onto the surface of the packaging substrate 3, thereby achieving the effect of stabilizing the amount of ink on the pre-coating rollers (pre-coating rollers 13 and pre-coating rollers 23) and coating rollers (coating rollers 14 and coating rollers 24).
[0044] In one embodiment, the first roller coating structure and the second roller coating structure are driven in opposite directions.
[0045] In the embodiment disclosed herein, the driving directions of the first coating structure 1 and the second coating structure 2 are opposite, one is clockwise and the other is counterclockwise, driving the pre-coating rollers (pre-coating roller 13 and pre-coating roller 23) and the coating rollers (coating roller 14 and coating roller 24) to rotate inward in meshing, thereby coating the two sides of the packaging substrate at the same time, ensuring that the ink coating processing equipment can achieve precise control of the differentiated ink on the two sides of the packaging substrate.
[0046] In one embodiment, the pre-coating roller and the coating roller are both made of rubber material.
[0047] In the disclosed embodiment, the pre-coating rollers (pre-coating roller 13 and pre-coating roller 23) and the coating rollers (coating roller 14 and coating roller 24) are both made of rubber material, and the coating wheel is a metal shaft wrapped with a layer of relatively soft rubber material, which can improve the uniformity, durability and applicability of the coating effect, thereby ensuring the reliability and stability of the ink rolling processing equipment.
[0048] like Figure 6 As shown, another embodiment of the present invention provides an ink rolling processing method, which is applied to an ink rolling processing device, wherein the ink rolling processing method includes:
[0049] S601: squeezing the positive scraper, the ink storage area and the pre-coating roller on two sides so that the ink in the ink storage area adjusts the ink amount on the surface of the pre-coating roller on two sides according to a preset positive scraper pressure.
[0050] In this embodiment, the positive scraper, the ink storage area and the pre-coating roller of the two sides are squeezed to make the positive scraper contact with the pre-coating roller, and the positive scraper pressure is controlled to squeeze the pre-coating roller, so that the ink in the ink storage area is preliminarily adjusted according to the preset positive scraper pressure. The ink rolling processing equipment controls the relative distance between the positive scraper and the pre-coating roller. The greater the positive scraper pressure, the greater the degree of squeezing of the pre-coating roller by the positive scraper, and the less the ink on the surface of the pre-coating roller. For example, when the positive scraper pressure of the A side is large, the ink on the surface of the pre-coating roller of the A side is small, and when the positive scraper pressure of the A side is small, the ink on the surface of the pre-coating roller of the A side is large. When the positive scraper pressure of the B side is large, the ink on the surface of the pre-coating roller of the B side is small. When the positive scraper pressure of the B side is small, the ink on the surface of the pre-coating roller of the B side is large.
[0051] In one embodiment, the positive scraper pressure is 0-20 bar.
[0052] In this embodiment, the positive scraper pressure is 0-20 bar, so that the adjustment of the positive scraper pressure has little effect on the amount of ink on the coating roller.
[0053] S602: squeezing the two sides of the pre-coating roller and the coating roller so that the amount of ink on the surface of the pre-coating roller is adjusted according to a preset differentiated pre-coating pressure.
[0054] In one embodiment, adjusting the amount of ink on the surfaces of two coating rollers according to a preset differentiated pre-coating pressure includes:
[0055] If the pre-coating pressure of surface A is set smaller than that of surface B, the coating roller surface of surface A has more ink, while the coating roller surface of surface B has less ink;
[0056] If the pre-coating pressure of surface A is set greater than the pre-coating pressure of surface B, the coating roller surface of surface A will have less ink, while the coating roller surface of surface B will have more ink.
[0057] In this embodiment, the pre-coating roller and the coating roller of two sides are squeezed to make the pre-coating roller and the coating roller contact, and the coating roller is squeezed by controlling the pre-coating pressure, so that the amount of ink on the surface of the pre-coating roller is adjusted according to the preset differentiated pre-coating pressure. When the coating rollers of two sides are in contact with the pre-coating rollers of the corresponding sides, the pre-coating pressures of the two sides can be set to be differentially adjusted, so that the squeezing force of the pre-coating rollers and the coating rollers of the two sides is different, so as to achieve the purpose of transferring different amounts of ink, wherein the ink roller processing equipment controls the relative distance between the pre-coating roller and the coating roller, and the greater the pre-coating pressure, the greater the squeezing degree of the pre-coating roller and the coating roller, and the less the amount of ink on the surface of the coating roller. For example, when the pre-coating pressure of side A is set lower than that of side B, the amount of ink on the coating roller surface of side A is more, and the amount of ink on the coating roller surface of side B is less. When the pre-coating pressure of side A is set higher than that of side B, the amount of ink on the coating roller surface of side A is less, and the amount of ink on the coating roller surface of side B is more. Finally, the amount of ink on the surfaces of the coating rollers of the two sides can be precisely controlled, and the thickness of the ink coated on the surface of the packaging substrate can be precisely controlled.
[0058] S603: Control the rotation of the two coating rollers to transfer different amounts of ink on the surface of the coating roller to the surface of the packaging substrate, so that the ink thickness on the junction surface and the welding surface of the packaging substrate is different.
[0059] In this embodiment, after obtaining the different amounts of ink on the surface of the coating roller, the different amounts of ink on the surface of the coating roller are transferred to the surface of the packaging substrate by controlling the rotation of the two coating rollers to ensure that the two coating rollers are in contact with the packaging substrate, so that the ink on the surface of the coating roller is evenly coated on the surface of the packaging substrate, and the ink thickness on the joint surface and the welding surface of the packaging substrate is different. The ink can be polymerized and solidified on the surface of the packaging substrate under a certain UV light source and temperature, and serves the purpose of insulation, anti-oxidation and aesthetics. Generally, there are dry film type and liquid type inks, which are then coated on the surface of the packaging substrate through the coating roller.
[0060] It should be noted that the embodiments of the present application may select different ink materials according to different usage scenarios, and the present application does not impose any limitation on this.
[0061] In one embodiment, there is a pre-coating pressure between the pre-coating roller and the coating roller, and the pre-coating pressure is 0-400 bar.
[0062] In this embodiment, when the pre-coating pressure acts on the pre-coating rollers of two sides at the same time, the pre-coating pressure can be set to 0-400 bar, and the pre-coating rollers of the two sides are in contact with the coating rollers of the corresponding sides respectively. By differentially adjusting the pre-coating pressures of the two sides, the extrusion forces between the pre-coating rollers and the coating rollers of the two sides are different, thereby achieving the purpose of transferring different amounts of ink. Ultimately, the amount of ink on the surface of the coating rollers on side A and side B can be precisely controlled, and the thickness of the ink coated on the surface of the packaging substrate can be precisely controlled.
[0063] In one embodiment, there is a coating pressure between the coating roller and the packaging substrate, and the coating pressure is 0-400 bar.
[0064] In this embodiment, when the coating pressure acts on the coating rollers on two sides at the same time, the coating pressure can be set to 0-400 bar. The pressure generated when the two coating rollers squeeze the packaging substrate against each other, the larger the value, the smaller the amount of ink on the surfaces of the two coating rollers, and the thinner the ink thickness coated on the surface of the packaging substrate. By adjusting the coating pressure, the ink thickness finally coated on the surface of the packaging substrate by the two coating rollers is different, thereby ensuring the precise control and measurement of the ink thickness to achieve ink differentiation.
[0065] In this embodiment, the positive scraper and the pre-coating roller are always in contact, and the coating roller has two states: one is that the coating roller is in contact with the pre-coating roller but not in contact with the packaging substrate. At this time, the pre-coating pressure can be adjusted differentially to achieve the purpose of different ink amounts on the two sides of the coating roller. The pre-coating pressure is adjusted differentially, and the pre-coating pressures on the A / B sides are different, that is, the degree of extrusion between the pre-coating roller and the coating roller on the A side and the degree of extrusion between the pre-coating roller and the coating roller on the B side are different, and finally the amount of ink on the surface of the coating roller on the A / B sides is different. The other is that the coating roller is not in contact with the pre-coating roller, but is in contact with the packaging substrate. At this time, the ink on the surface of the coating roller (the amount of ink on the surfaces of the two coating rollers is already different) is coated onto the surface of the packaging substrate (the coating pressure on the A / B surface is actually the force generated by the contact between the coating roller on the A side and the coating roller on the B side). Since the amount of ink on the surfaces of the coating rollers on the A / B surfaces is different, the thickness of the ink finally coated on the surface of the packaging substrate is different, that is, the differentiated ink thickness required for this application.
[0066] In summary, the present invention provides an ink roller coating processing equipment and a processing method, which squeezes the positive scraper, ink storage area and pre-coating roller of two sides in the ink roller coating processing equipment so that the ink in the ink storage area adjusts the ink amount on the surface of the two pre-coating rollers according to the preset positive scraper pressure, and then squeezes the pre-coating roller and coating roller of two sides in the ink roller coating processing equipment so that the ink amount on the surface of the pre-coating roller is adjusted according to the preset differentiated pre-coating pressure. Finally, the rotation of the coating rollers of the two sides is controlled to transfer the different ink amounts on the surface of the coating rollers to the surface of the packaging substrate, so that the ink thickness of the joint surface and the welding surface of the packaging substrate is different. The present application improves the precise control of the differential ink of the two sides of the packaging substrate by adjusting the ink amount on the surface of the coating rollers of the two sides according to the preset differentiated pre-coating pressure, realizes the precise control of the differentiated ink thickness, improves the product yield and reduces the scrapping cost of defective products.
