In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
Referring to fig. 1 to 3, the present embodiment provides a screen printing plate 100, the screen printing plate 100 including:
the composite screen printing plate comprises an elastic layer 120 and a rigid layer 130 which are stacked, wherein a printing pattern groove 150 is formed through the elastic layer 120 and the rigid layer 130;
and a frame 110 surrounding and disposed on the sidewall of the composite screen and connected to the sidewall of the composite screen.
In the screen printing plate provided by this embodiment, the composite screen plate includes the elastic layer 120 and the rigid layer 130, the elastic layer 120 and the rigid layer 130 jointly penetrate through and are provided with the printing pattern groove 150, and the rigid layer 130 is suitable for being away from the printing stock in the screen printing process. The rigid layer 130 may be patterned using laser etching to form the printed pattern grooves 150, resulting in a higher pattern accuracy in the rigid layer. The pattern precision of the screen printing screen plate is determined by the pattern precision in the rigid layer and is not influenced by the pattern precision in the elastic layer. In addition, this embodiment is through the setting of elastic layer 120 for the printing material pushes away to print and fills the in-process that upwards promotes the screen printing otter board after printing the figure groove, and elastic layer deformation produces certain ascending elastic restoring force, thereby makes the elastic layer upwards displacement, can make the in-process direction that the screen printing otter board was promoted and promotes more accurate on the one hand, and on the other hand elastic layer self hardness is lower relatively, is difficult for causing deformation or wearing and tearing to just fashioned seal.
In a specific application scenario, the screen printing screen of the embodiment is used for printing the grid line electrode of the solar cell, and the printed matter is the grid line electrode of the solar cell. The grid line electrode comprises a plurality of main grid line electrodes arranged in parallel, for example: 9 main grid electrode electrodes arranged in parallel; the solar cell further comprises a plurality of secondary grid line electrodes which are perpendicular to the main grid line electrodes, wherein the specific number of the secondary grid line electrodes can be dozens of secondary grid line electrodes or even hundreds of secondary grid line electrodes according to the size of the solar cell, and detailed description is omitted here. The main function of the secondary grid electrode is to guide current, and the function of the main grid electrode is to collect and gather the current of the secondary grid electrode.
In the present embodiment, the screen printing plate 100 has a plurality of printing pattern grooves 150, and the plurality of printing pattern grooves 150 together constitute a printing pattern. In other embodiments, the printed pattern slot 150 may be a continuous printed pattern slot, with a single printed pattern slot alone forming the printed pattern.
Further, referring to fig. 3, in the present embodiment, the elastic layer 120 includes a pattern region b and a connection region a; the connection area a surrounds the graphic area b, and the connection area a is connected to the frame 110. Because the connecting area a is connected to the frame 110, the connecting area a is pressed down along with the pressing down of the graphic area b in the process of pushing, and after the pushing is finished, because the connecting area a is connected to the frame 110, the elastic force for restoring the deformation provided by the frame 110 is provided besides the self resilience force, so the resilience effect is better.
In this embodiment, the edge shape of the pattern region b is rectangular. In other embodiments, the shape of the edge of the pattern region b may also be a circle, an ellipse, a triangle, a parallelogram, a trapezoid, etc., which may be determined according to the specification and shape of the solar cell to be printed with the grid line electrode, and is not limited herein.
Referring to fig. 1 and 3, in the present embodiment, the rigid layer 130 completely covers the pattern region b, and at least a portion of the connection region a is exposed from the rigid layer 130. The smaller the area of the connection region a covered by the rigid layer 130, the smaller the size of the rigid layer 130 itself, and the more significant the effect of the smaller-sized rigid layer 130 on the resilient force of the elastic layer 120 is for the same size of elastic layer. In other embodiments, the rigid layer 130 completely covers the graphic region b and the connection region a. The solution of the rigid layer 130 completely covering the connection area a is easier to process than the solution of the rigid layer 130 only covering the graphic area b.
The screen printing screen is bonded by a glue layer 140, the glue layer 140 is located between the rigid layer 130 and the elastic layer 120, and the printing pattern groove 140 also penetrates through the glue layer 140. That is, the rigid layer 130 and the elastic layer 120 are integrally combined by the adhesive layer 140 to form the composite screen. In the embodiment, the adhesive layer 140 is a hot melt adhesive layer, but may be other adhesive adhesives with good adhesiveness and stable performance.
The main raw material of the existing metal mesh plate is a steel wire mesh which is formed by weaving steel wires with low wire diameter (11-16 μm) in a longitudinal and transverse mode, in order to pursue narrower fine grid line electrodes, a steel wire mesh cloth with higher mesh number and narrower wire diameter needs to be used, and the cost of the steel wire mesh cloth in each metal mesh plate exceeds 1500 yuan. In this embodiment, the rigid layer 130 of the screen printing screen is a metal film layer. More specifically, the metal film layer includes: a steel metal film, a nickel metal film, a titanium metal film, an alloy steel metal film, a nickel alloy metal film, or a titanium alloy metal film. By means of the rigid layer 3, the screen printing stencil 100 can achieve a precision comparable to that of the prior art metal stencil and at a lower cost.
The thickness of the rigid layer is 5 μm to 50 μm, and may be, for example, 5 μm, 10 μm, 20 μm, 30 μm, 40 μm, or 50 μm.
In this embodiment, the elastic layer 120 of the screen printing plate is a polyester material layer. More specifically, the polyester material layer comprises a polyester film or a polyester mesh. The polyester film may form a relatively stable tension, and the tension of the polyester net may be adjusted within a certain range by a net stretching manner when the frame 110 is coupled.
The thickness of the elastic layer is 10 μm to 80 μm, and may be, for example, 10 μm, 20 μm, 40 μm or 80 μm.
The opening of the existing single-layer polyester printing screen plate can only reach about 24 mu m, and the width of the printed pattern is about 40 mu m to 50 mu m. The opening of the screen printing screen plate provided by the embodiment can reach 13-15 mu m, the width of the printed pattern can be accurate to 20-30 mu m, and the pattern precision is better.
For a single-layer metal steel wire screen plate, the tension is generally not more than 20N, and the wire screen plate with the wire diameter of 11 mu m is about 15N-17N. The screen printing screen plate provided by the embodiment can provide 20N-30N of tension, and the elastic restoring force is stronger.
Therefore, the screen printing screen plate of the embodiment uses the metal film layer as the rigid layer of the composite screen printing plate, so that sufficient accuracy for realizing printing is provided; and meanwhile, the polyester material layer is provided as the elastic layer of the composite screen printing plate, so that the sufficient toughness for realizing printing is provided, the better printing effect can be ensured, the cost is lower even if the single-layer steel wire mesh is used for comparing with the existing metal screen plate, and meanwhile, the abrasion of printed matters can be avoided.
Example 2
Referring to fig. 4, the present embodiment provides a method for manufacturing a screen printing plate corresponding to the method in embodiment 1, including the following steps:
step S1: providing an elastic layer;
step S2: providing a rigid layer, and compounding the rigid layer and the elastic layer together to form a composite screen printing plate;
step S3: providing a frame, wherein the frame surrounds the side wall of the composite screen printing plate and is connected with the side wall of the elastic layer;
step S4: and patterning the composite screen to form a printed pattern groove which penetrates through the elastic layer and the rigid layer together.
In the method for manufacturing the screen printing plate according to this embodiment, the composite screen plate is patterned to form the printing pattern groove penetrating through the elastic layer and the rigid layer. The pattern accuracy of the screen printing screen is determined by the pattern accuracy in the rigid layer, and is not influenced by the pattern accuracy in the elastic layer, so that higher pattern accuracy can be obtained.
Further, the process of patterning the composite screen in step S2 is a laser etching process. Compared with a single-layer polyester screen printing plate, the single-layer polyester screen printing plate can only be patterned by a photoetching method, so that the relative pattern precision is lower. Due to the arrangement of the rigid layer, the composite screen plate of the embodiment can be patterned by using a laser etching process. The laser etching process is to etch a micro-fine groove with a set width and a set depth in the composite screen printing plate by adopting a high-energy pulse laser beam. The laser etching process has the advantages of no contact, high flexibility, high processing speed, no noise, small heat affected zone, capability of focusing on a laser wavelength-level extremely small light spot and the like, and can obtain good dimensional precision and processing quality, so that the screen printing screen plate can have higher graphic precision.
Further, the step of compounding the rigid layer and the elastic layer together comprises: coating a glue layer on the surface of one side of the rigid layer and drying; and compounding the rigid layer and the elastic layer together through the glue layer at a set temperature. Preferably, the step of compounding the rigid layer and the elastic layer together comprises: coating a hot melt adhesive layer on the surface of one side of the rigid layer and drying; the rigid layer and the elastic layer are compounded together through the hot melt adhesive layer at the temperature of 50-200 ℃. Preferably, the rigid layer and the elastic layer are compounded together through a hot melt adhesive layer at the temperature of 70-170 ℃.
Further, as shown in fig. 5, the method for manufacturing the screen printing plate further includes the following steps:
step S5: cleaning; and after the composite screen printing plate is patterned, cleaning the composite screen printing plate and the frame.
Step S6: drying; and drying the cleaned composite screen and the frame.
After the screen printing screen plate is manufactured by the method, the screen printing screen plate is inspected, the film thickness, the line width, the tension and the like of the composite screen plate formed by the metal film layer/the polyester material layer are measured and are well matched with design parameters, and a better printing effect than that of the existing polyester screen plate or the existing metal screen plate can be obtained.
