Description

Technical Field

[0001] This invention relates to the field of solar cells, and more specifically, to a method and system for detecting the mixing ratio of two-component silica gel. Background Technology

[0002] Solar energy is a new type of renewable energy source, characterized by its unlimited reserves, free use, and lack of pollutants such as wastewater and waste residue during operation, making it green and environmentally friendly. Solar photovoltaic modules can convert the energy emitted by the sun into electrical energy, and the photovoltaic industry is developing very rapidly today.

[0003] Currently, the sealing material used for photovoltaic modules is condensation-type room temperature vulcanizing silicone rubber, or simply silicone. Silicone serves as the encapsulation material for photovoltaic modules, protecting internal electrical components from external environmental influences. Silicone includes single-component and two-component silicone. Two-component silicone has gained widespread application due to its superior physical and chemical properties.

[0004] In current production, A and B adhesives are mixed using a glue applicator to obtain two-component silicone. The ratio of A and B adhesives in the two-component silicone is changed by altering the pressure value in the glue applicator. However, there is a lack of effective monitoring methods to detect whether the ratio of A and B adhesives in the two-component silicone meets the preset requirements.

[0005] Therefore, there is an urgent need to provide a method and system for detecting the mixing ratio of two-component silica gel that can effectively monitor the silica gel ratio in two-component silica gel. Summary of the Invention

[0034] The production execution system includes a storage module, a receiving module, and a computing module, wherein the storage module and the receiving module are both connected to the computing module.

[0046] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0047] Other features and advantages of the invention will become clear from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. Attached Figure Description

[0051] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0052] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0053] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0054] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0056] Reference Figure 1 This invention provides a method for detecting the mixing ratio of two-component silica gel, comprising:

[0057] S1 obtains standard silicone, which includes first silicone and second silicone, and the mass ratio of first silicone to second silicone is a first ratio;

[0058] S2 detects the grayscale of standard silicone, and the grayscale value of standard silicone is the first grayscale value;

[0059] S3 tests the fluorescence intensity of standard silica gel, and the fluorescence intensity value of standard silica gel is the first fluorescence intensity value;

[0060] S4 obtains the target silicone, which includes a third silicone and a fourth silicone, with the mass ratio of the third silicone to the fourth silicone being a second ratio; the composition of the third silicone is the same as that of the first silicone, and the composition of the fourth silicone is the same as that of the second silicone.

[0061] S5 detects the grayscale of the target silicone, and the grayscale value of the target silicone is the second grayscale value;

[0062] S6 detects the fluorescence intensity of the target silica gel, and the fluorescence intensity value of the target silica gel is the second fluorescence intensity value;

[0063] S7 compares the first ratio with the second ratio to obtain the difference A between the second ratio and the first ratio;

[0064] S8 compares the first gray value with the second gray value to obtain the difference B between the second gray value and the first gray value;

[0065] S9 compares the first fluorescence intensity value with the second fluorescence intensity value to obtain the difference C between the second fluorescence intensity value and the first fluorescence intensity value;

[0066] The target silicone is qualified when A, B, and C are all positive or when A, B, and C are all negative.

[0067] When A, B, and C are not all positive numbers, or when A, B, and C are not all negative numbers, the target silicone is unqualified, and the production execution system will issue an alarm.

[0068] It should be noted that the standard silicone is a known qualified silicone. The first proportion, first grayscale value, and first fluorescence intensity value of the standard silicone are used as a reference. The second proportion, second grayscale value, and second fluorescence intensity value of the prepared target silicone are compared with the first proportion, first grayscale value, and first fluorescence intensity value. The qualification of the target silicone is determined by judging whether the second proportion, second grayscale value, and second fluorescence intensity value of the target silicone change with the same trend. Here, difference A is the value obtained by subtracting the first proportion from the second proportion, difference B is the value obtained by subtracting the first grayscale value from the second grayscale value, and difference C is the value obtained by subtracting the first fluorescence intensity value from the second fluorescence intensity value. When A, B, and C are all positive or when A, B, and C are all negative, that is, the second proportion, second grayscale value, and second fluorescence intensity value of the target silicone change with the same trend, the target silicone is qualified. When A, B, and C are not all positive or when A, B, and C are not all negative, that is, the second proportion, second grayscale value, and second fluorescence intensity value of the target silicone change with different trends, the target silicone is unqualified, and the production execution system alarms.

[0069] It is understandable that different ratios of the two-component silicone sealant determine the curing time and the adhesion between the cured frame and the glass. This embodiment detects the grayscale value of the two-component silicone sealant while simultaneously measuring its fluorescence intensity, comparing the two data in real time, and automatically triggering an alarm for abnormal data. This effectively monitors changes in the component ratios of the two-component silicone sealant during continuous production, not only significantly shortening the detection time but also providing operators with direct evidence to determine the components, reducing production losses caused by improper component ratios.

[0070] Table 1. Silica ratio, gray value, and fluorescence intensity value of two-component silica gel.

[0071] Silicone ratio grayscale value fluorescence intensity value Standard silicone one 1:1 100 130 Target silicone one 1.1:1 110 140 Target silicone two 1.2:1 108 142 Target silicone three 1.3:1 99 126 Target silicone four 1.3:1 130 128

[0072] For example, referring to Table 1, the silica ratio of standard silica gel one is 1:1, that is, the first ratio of standard silica gel one is 1:1, which means that the mass ratio of the first silica gel to the second silica gel in standard silica gel one is 1:1; the silica ratio of target silica gel one is 1.1:1, that is, the second ratio of target silica gel one is 1.1:1, which means that the mass ratio of the third silica gel to the fourth silica gel in target silica gel one is 1.1:1. The second ratio (1.1) of target silica gel one is greater than the first ratio (1) of standard silica gel one; the composition of the third silica gel is the same as that of the first silica gel, and the composition of the fourth silica gel is the same as that of the second silica gel. That is, compared with standard silica gel one, the proportion of the third silica gel in target silica gel one is increased, so the gray value and fluorescence intensity value of target silica gel one should be increased accordingly. The difference between the second proportion of target silicone one and the first proportion of standard silicone one is A1 = 1.1 - 1 = 0.1 > 0. The difference between the second gray value of target silicone one and the first gray value of standard silicone one is B1 = 110 - 100 = 10 > 0. The difference between the fluorescence intensity value of target silicone one and the first fluorescence intensity value of standard silicone one is C1 = 140 - 130 = 10 > 0. Since A1, B1, and C1 are all positive numbers, when the proportion of the third silicone in target silicone one increases, the gray value and fluorescence intensity value of target silicone one also increase accordingly. Therefore, target silicone one is qualified.

[0073] Furthermore, when the difference A is 0.1N, the difference B should be between 8N and 10N, and the difference C should be between 10N and 12N. Referring to Table 1, the silica ratio of target silica gel two is 1.2:1, that is, the second ratio of target silica gel two is 1.2:1, which means the mass ratio of the third silica gel to the fourth silica gel in target silica gel two is 1.2:1; the difference between the second ratio of target silica gel two and the first ratio of standard silica gel one is A2 = 1.2 - 1 = 0.2 > 0; the difference between the second gray value of target silica gel two and the first gray value of standard silica gel one is B2 = 108 - 100 = 8 > 0; the difference between the fluorescence intensity value of target silica gel two and the first fluorescence intensity value of standard silica gel one is C2 = 142 - 130 = 12 > 0. A, B, and C are all positive numbers. However, when the difference A is 0.2, the difference B should be between 16 and 20, and the difference C should be between 20 and 24. The difference B2 = 8 and the difference C2 = 12. The difference B2 and the difference C2 do not meet the requirements, so the target silicone is unqualified.

[0074] For example, referring to Table 1, the silicone ratio of target silicone three is 1.3:1, that is, the second ratio of target silicone three is 1.3:1, which means that the mass ratio of the third silicone to the fourth silicone in target silicone three is 1.3:1; the difference between the second ratio of target silicone three and the first ratio of standard silicone one is A3 = 1.3 - 1 = 0.3 > 0, the difference between the second gray value of target silicone three and the first gray value of standard silicone one is B3 = 99 - 100 = -1 < 0, and the difference between the fluorescence intensity value of target silicone three and the first fluorescence intensity value of standard silicone one is C3 = 126 - 130 = -4 < 0. A3 is a positive number, while B3 and C3 are both negative numbers. A, B, and C are different and are positive or negative, so target silicone three is unqualified.

[0075] For example, referring to Table 1, the silicone ratio of target silicone four is 1.3:1, that is, the second ratio of target silicone four is 1.3:1, which means that the mass ratio of the third silicone to the fourth silicone in target silicone four is 1.3:1; the difference between the second ratio of target silicone four and the first ratio of standard silicone one is A4 = 1.3 - 1 = 0.3 > 0; the difference between the second gray value of target silicone four and the first gray value of standard silicone one is B4 = 130 - 100 = 30 > 0; the difference between the fluorescence intensity value of target silicone four and the first fluorescence intensity value of standard silicone one is C4 = 128 - 130 = -2 < 0. A4 and B4 are both positive numbers, and C4 is a negative number. A, B, and C are different and are positive or negative, so target silicone four is unqualified.

[0076] In some optional embodiments, the two-component silica gel mixing ratio detection method further includes:

[0077] Preset first ratio;

[0078] Weigh out the first silicone and the second silicone according to the first ratio;

[0079] A first phosphor is added to the first silica gel;

[0080] The first and second silicone are mixed in a glue applicator to obtain standard silicone.

[0081] It should be noted that the prepared standard silica gel is a silica gel that has passed re-inspection. The standard silica gel is used as a control group to determine whether the target silica gel is qualified. When only the grayscale of the two-component silica gel is detected, i.e., with only one auxiliary judgment device, the system cannot detect accidental misjudgments in a timely manner. This embodiment adds a first phosphor to the first silica gel to detect its fluorescence intensity value. The grayscale value of the two-component silica gel is detected simultaneously with the fluorescence intensity measurement. Real-time comparison of the two data provides the operator with direct evidence for component judgment, improving the accuracy of the judgment system, effectively monitoring changes in the component ratio of the two-component silica gel during continuous production, and reducing production losses caused by improper component ratios.

[0082] In some optional embodiments, the first phosphor is any one of leak detection phosphor, LED phosphor, tri-color phosphor, calcium halophosphate phosphor, rare earth phosphor, and zinc sulfide phosphor.

[0083] It should be noted that the second phosphor can be any one of leak detection phosphor, LED phosphor, tri-color phosphor, calcium halophosphate phosphor, rare earth phosphor, and zinc sulfide phosphor. Furthermore, the second phosphor has the same composition as the first phosphor; for example, when the first phosphor is an LED phosphor, the second phosphor is also an LED phosphor.

[0084] It is understandable that leak detection phosphors, LED phosphors, tri-color phosphors, calcium halophosphate phosphors, rare earth phosphors, and zinc sulfide phosphors all exhibit cold luminescence based on photoluminescence. By adding phosphors to detect the fluorescence intensity of two-component silicone, and simultaneously measuring the fluorescence intensity while detecting the grayscale value of the two-component silicone, and comparing the two data in real time, operators can be given a direct basis for determining the components. This effectively monitors changes in the component ratio of two-component silicone during continuous production and reduces production losses caused by improper component ratios.

[0085] In some optional embodiments, the mass ratio of the first phosphor to the first silica gel is... between.

[0086] It should be noted that the higher the amount of the first phosphor added, the greater the fluorescence intensity. The mass ratio of the second phosphor to the third silica gel in the target silica gel is equal to the mass ratio of the first phosphor to the first silica gel. This is to avoid affecting the judgment of the fluorescence intensity value of the target silica gel.

[0087] It is understandable that the mass ratio of the first phosphor to the first silica gel can be... The mass ratio of the first phosphor to the first silica gel can also be any value within the above range, and is not limited here. When the mass ratio of the first phosphor to the first silica gel is less than... When the amount of the first phosphor added is too small, the fluorescence intensity detection result will have a large error; when the mass ratio of the first phosphor to the first silica gel is greater than... If too much of the first phosphor is added, it can easily lead to discoloration after the module sealant cures, affecting the module's power generation efficiency. Therefore, the mass ratio of the first phosphor to the first silicone sealant should be... This avoids affecting the fluorescence intensity detection while preventing discoloration after the component sealant cures.

[0088] In some optional embodiments, the two-component silica gel mixing ratio detection method further includes:

[0089] Preset second ratio;

[0090] Weigh out the third and fourth silicone rubbers according to the second ratio;

[0091] A second phosphor is added to the third silica gel, and the mass ratio of the second phosphor to the third silica gel is equal to the mass ratio of the first phosphor to the first silica gel.

[0092] The third and fourth silicone materials are mixed in the glue applicator to obtain the target silicone material.

[0093] It should be noted that the mass ratio of the second phosphor to the third silica gel is... Between these two points, the mass ratio of the second phosphor to the third silica gel can be... The mass ratio of the second phosphor to the third silica gel can also be any value within the above range, and is not limited here. The mass ratio of the second phosphor to the third silica gel is equal to the mass ratio of the first phosphor to the first silica gel. For example, when the mass ratio of the first phosphor to the first silica gel is... At that time, the mass ratio of the second phosphor to the third silica gel was also [missing information]. .

[0094] This embodiment detects the fluorescence intensity of the third silica gel by adding a second phosphor to the third silica gel. The grayscale value of the two-component silica gel is detected and the fluorescence intensity is measured at the same time. The two data are compared in real time, which can provide the operator with a direct basis for judging the components. This effectively monitors the changes in the component ratio of the two-component silica gel in continuous production and reduces production losses caused by improper component ratio.

[0095] In some alternative embodiments, the first silicone rubber comprises dihydroxy polydimethylsiloxane, and the second silicone rubber comprises a crosslinking agent and a coupling agent.

[0096] It should be noted that silicone includes single-component silicone and two-component silicone. Single-component silicone contains only one component, and the main agent and curing agent are stored together. It is used directly when applying adhesive, and it cures gradually from the surface to the inside, making it difficult to cure a very thick adhesive layer.

[0097] In this embodiment, both the standard silicone and the target silicone are two-component silicones. Taking the standard silicone as an example, the two-component adhesive consists of a main agent (first silicone) and a curing agent (second silicone). Before use, the first and second silicone components need to be mixed in proportion. During curing, the inside and outside are cured simultaneously, allowing for the curing of a thicker adhesive layer. Specifically, the cross-linking and curing process of silicone requires the simultaneous presence of moisture and a cross-linking agent to initiate the curing reaction. The first silicone includes dihydroxy polydimethylsiloxane, filler, diluent, and moisture. The second silicone includes a cross-linking agent and a coupling agent. The cross-linking agent can be dicumyl peroxide (DCP), benzoyl peroxide (BPO), or di-tert-butyl peroxide (DTBP), and the coupling agent can be a silane coupling agent: KH550, KH560, or KH570.

[0098] In some optional embodiments, the mass ratio of the first silicone to the second silicone is between 1:1 and 9:1; the mass ratio of the third silicone to the fourth silicone is between 1:1 and 9:1.

[0099] It should be noted that the mass ratio of the first silicone to the second silicone can be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1 or 9:1, and the mass ratio of the first silicone to the second silicone can also be any value within the above range, without specific limitation here.

[0100] It's understandable that the first silicone is the matrix and the second silicone is the initiator. When the mass ratio of the first to the second silicone is less than 1:1 (i.e., the second silicone is more abundant than the first), the two-component silicone cures too quickly, easily creating cavities and affecting the encapsulation effect. When the mass ratio is greater than 9:1, the first silicone is excessive, resulting in slow curing and impacting the production process. Therefore, a mass ratio of the first to the second silicone between 1:1 and 9:1 ensures the encapsulation effect without affecting the production process.

[0101] Similarly, the mass ratio of the third silicone to the fourth silicone can also be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1 or 9:1, and the mass ratio of the third silicone to the fourth silicone can also be any value within the above range, without specific limitations.

[0102] Reference Figure 2 The present invention also provides a two-component silicone mixing ratio detection system, comprising: a glue applicator 1, a grayscale sensor 2, a fluorescence spectrophotometer 3, and a production execution system 4, wherein the grayscale sensor 2 and the fluorescence spectrophotometer 3 are both connected to the production execution system 4.

[0103] The production execution system 4 includes a storage module 41, a receiving module 42, and a computing module 43, with the storage module 41 and the receiving module 42 both connected to the computing module 43;

[0104] Standard silicone and target silicone are prepared in glue applicator 1; the standard silicone includes first silicone and second silicone, and the mass ratio of the first silicone to the second silicone is a first ratio; the target silicone includes third silicone and fourth silicone, and the mass ratio of the third silicone to the fourth silicone is a second ratio; the first ratio and the second ratio are stored in storage module 41;

[0105] Grayscale sensor 2 detects the grayscale of standard silicone and target silicone. The grayscale value of the standard silicone is the first grayscale value, and the grayscale value of the target silicone is the second grayscale value. The first grayscale value and the second grayscale value are uploaded to the production execution system 4.

[0106] The fluorescence spectrophotometer 3 detects the fluorescence intensity of the standard silica gel and the target silica gel. The fluorescence intensity value of the standard silica gel is the first fluorescence intensity value, and the fluorescence intensity value of the target silica gel is the second fluorescence intensity value. The first fluorescence intensity value and the second fluorescence intensity value are uploaded to the production execution system 4.

[0107] The receiving module 42 receives the first gray value, the second gray value, the first fluorescence intensity value, and the second fluorescence intensity value;

[0108] The calculation module 43 retrieves the first ratio and the second ratio from the storage module 41, and the calculation module 43 retrieves the first gray value, the second gray value, the first fluorescence intensity value and the second fluorescence intensity value from the receiving module 42;

[0109] The calculation module 43 calculates the difference between the second ratio and the first ratio as A, the calculation module 43 calculates the difference between the second gray value and the first gray value as B, and the calculation module 43 calculates the difference between the second fluorescence intensity value and the first fluorescence intensity value as C.

[0110] The target silicone is qualified when A, B, and C are all positive or when A, B, and C are all negative.

[0111] It should be noted that a standard silicone with a preset first ratio is first prepared in the glue applicator 1 (Shanghai Shengpu SPZ-2100G). A small amount (about 5g) of the standard silicone is placed in the sample chambers of the grayscale sensor 2 (Ai'enai Technology (Tianjin) Co., Ltd. LUKAS-M606S) and the fluorescence spectrometer 3 respectively. The first grayscale value and the first fluorescence intensity value of the standard silicone are detected. The first ratio, the first grayscale value and the first fluorescence intensity value are stored in the storage module 41 as a reference.

[0112] The second proportion of target silicone is prepared in the glue applicator 1. Every certain time (0.5h), a small amount of target silicone (the mass of the target silicone to be tested is the same as that of the standard silicone) is taken with a glue pen and placed in the sample chambers of the grayscale sensor 2 and the fluorescence spectrometer 3 respectively. The test equipment provides the second grayscale value and the second fluorescence intensity value in real time. The calculation module 43 of the production execution system 4 calculates the difference between the second proportion and the first proportion as A, the difference between the second grayscale value and the first grayscale value as B, and the difference between the second fluorescence intensity value and the first fluorescence intensity value as C, and automatically compares the consistency of the values. When A, B, and C are all positive or when A, B, and C are all negative, the target silicone is qualified.

[0113] It is understood that this embodiment, by detecting the grayscale value of the two-component silica gel while simultaneously measuring the fluorescence intensity, and comparing the two data in real time, can provide the operator with a direct basis for determining the components, improve the accuracy of the determination system, and effectively monitor the changes in the component ratio of the two-component silica gel during continuous production.

[0114] Continue to refer to Figure 2 In some optional embodiments, the production execution system 4 also includes an alarm module 44;

[0115] When A, B, and C are not all positive numbers or when A, B, and C are not all negative numbers, the target silicone is unqualified. The calculation module 43 sends a signal to the alarm module 44, and the alarm module 44 rings an alarm.

[0116] Understandably, when only the grayscale of two-component silicone is detected, i.e., with only one auxiliary judgment device, the system cannot detect occasional misjudgments in a timely manner. This embodiment detects the grayscale value of the two-component silicone while simultaneously measuring the fluorescence intensity, and compares the two data in real time. This provides the operator with direct evidence for judging the components, improves the accuracy of the judgment system, avoids misjudgments, and, when the target silicone is detected to be unqualified, the alarm module 44 promptly sounds an alarm, reducing production losses caused by improper component ratios.

[0117] As can be seen from the above embodiments, the two-component silica gel mixing ratio detection method and system provided by the present invention achieves at least the following beneficial effects:

[0118] This invention provides a method for detecting the mixing ratio of two-component silica gel, comprising: obtaining standard silica gel, wherein the mass ratio of the first silica gel to the second silica gel is a first ratio; the grayscale value is a first grayscale value; the fluorescence intensity value is a first fluorescence intensity value; obtaining target silica gel, comprising a third silica gel and a fourth silica gel, wherein the mass ratio of the third silica gel to the fourth silica gel is a second ratio; the grayscale value is a second grayscale value; the fluorescence intensity value is a second fluorescence intensity value; the difference A between the second ratio and the first ratio; the difference B between the second grayscale value and the first grayscale value; the difference C between the second fluorescence intensity value and the first fluorescence intensity value; when A, B, and C are all positive or when A, B, and C are all negative, the target silica gel is qualified; when A, B, and C are not all positive or when A, B, and C are not all negative, the target silica gel is unqualified, and the production execution system alarms. By detecting the grayscale value of the two-component silica gel and measuring the fluorescence intensity simultaneously, the two data are compared in real time, and abnormal data triggers an automatic alarm. It can effectively monitor changes in the proportion of two-component silica gel components during continuous production, which not only effectively shortens the detection time, but also provides operators with direct basis for determining the components, reducing production losses caused by improper component ratios.
