Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
Before describing the method for evaluating the edge lamination safety distance of the photovoltaic module laminating machine, the structural and technical problems of the laminating machine will be described.
As shown in fig. 2, the bottom plate of the laminator comprises a laminator flange 2, a laminator heating area, and a laminator bottom plate vacuum hole 1, wherein the laminator flange 2 is located inside the laminator heating bottom plate edge 3. The cloth is put respectively in the superiors and the bottom of photovoltaic module product under the laminator, and as drop cloth and floorcloth, the antiseized nature of cloth under the laminator is utilized, prevents that glued membrane or other materials from gluing on the laminator under high temperature environment. After the lower cloth of the laminating machine is arranged on the laminating machine, the lower cloth edge 5 of the laminating machine is positioned between the flange 2 of the laminating machine and the heating bottom plate edge 3 of the laminating machine. The photovoltaic module product is placed in the area inside the laminating machine flange 2 for lamination, the laminating machine flange 2 is close to the edge of the laminating machine, but the photovoltaic product laminated at the position close to the laminating machine flange 2 is easy to have the phenomenon of uneven stress due to the supporting effect of the flange; therefore, a safety region for lamination within a certain distance from the flange of the laminating machine needs to be obtained by an evaluation method so as to ensure the stability of product lamination.
A method for evaluating the edge lamination safety distance of a photovoltaic module laminator according to an embodiment of the present invention is described in detail below with reference to fig. 1-5, and includes the following steps:
s1, preparing a plurality of samples to be laminated.
Specifically, several samples to be laminated were prepared which could be used to test the degree of crosslinking and the degree of peeling. The size of the sample to be laminated can be cut according to the size of the model of the product, and it is understood that the size of the sample to be laminated is set according to the size of the model of the photovoltaic module laminated by the actual laminating machine.
In one embodiment of the present invention, the several samples to be laminated include at least glass, an adhesive film, and a back sheet, which are sequentially laminated. In a normal production process, namely a non-test state, the photovoltaic module product comprises glass, an adhesive film, a battery, the adhesive film and a back plate which are sequentially stacked, and because the cost of the battery is higher and the test result is not influenced by testing with a sample without the battery, the battery is not placed in the sample to be laminated in the test stage, so that the test cost is reduced.
Preferably, several samples of the same size to be laminated are prepared. The same size of sample to be laminated improves the accuracy of the test, and different sizes of sample to be laminated reduce the accuracy of the test.
S2, placing a plurality of samples to be laminated at different positions of the flange 2 of the laminating machine, wherein the distance between each sample to be laminated and the flange 2 of the laminating machine is unequal, and performing lamination sample preparation on the samples to be laminated to obtain a laminated finished product. As shown in fig. 2, several samples to be laminated are placed at the laminator flange 2, and the distance between each sample to be laminated and the laminator flange 2 is not equal.
For example, as shown in fig. 2, a first sample to be laminated 4a, a second sample to be laminated 4b, and a third sample to be laminated 4c of the several samples to be laminated are placed at positions at a first distance, a second distance, and a third distance, respectively, from the laminator flange 2; the first distance, the second distance and the third distance are sequentially increased. The plurality of samples to be laminated include a first sample to be laminated 4a, a second sample to be laminated 4b and a third sample to be laminated 4c, and the first sample to be laminated 4a, the second sample to be laminated 4b and the third sample to be laminated 4c are respectively at a first distance, a second distance and a third distance from the laminator flange 2. Several samples to be laminated are placed at different distances from the laminator flange 2 to obtain a safe distance. The greater the number of samples to be laminated, i.e. the greater the different distances of the laminated samples from the laminator flange 2, a corresponding improvement in the accuracy of the safety distance is obtained.
Preferably, the value of the first distance is zero, which is to be understood as the edge of the first sample to be laminated 4a contacting the laminator flange 2.
Preferably, the difference of the third distance minus the second distance is equal to the difference of the second distance minus the first distance, which is to be understood as the difference of the distances between the several samples to be laminated and the laminator flange 2 being incremented or decremented in an equidistant manner. The equidistant increasing or decreasing improves the convenience of obtaining the safe distance.
It should be noted that: the distance between each laminate sample and the laminator flange can be set based on experience in the actual application. For example, the difference between the third distance and the second distance may be selected to be an appropriate distance difference, for example, 1cm,1.5cm,2cm,2.5cm,3cm,3.5cm,4cm,4.5cm, 5cm, or the like. Preferably 1cm to 3cm, which allows a more precise derivation of the safe distance.
And S3, cutting one side of the laminated finished product, which is close to the flange 2 of the laminating machine, to obtain a plurality of detection products and marking the detection products.
The portion of the laminated product obtained in step S2 is cut, the side of the laminated product close to the laminator flange 2 is cut, and cut into strips of equal width. Such as: cutting into 5-10 parts of detection products with the same size to be subjected to the detection of the peeling force and the crosslinking degree.
Each test item needs to be marked and the position of the test item on the laminator is marked to determine the separation of each test item from the laminator flange 2.
And S4, detecting the peeling strength value and the crosslinking degree value of each detection product.
And (4) detecting the peel strength value and the crosslinking degree value of the detection product obtained by cutting in the step (S3) so as to judge whether the detection product meets the lamination standard or not. The method for measuring the peel strength and the crosslinking degree can adopt a conventional test method, and is not limited herein.
And S5, acquiring the detection product with qualified peel strength value and crosslinking degree value and the corresponding position of the detection product on a laminating machine to obtain the safe distance during lamination.
Specifically, the minimum distance between the qualified test product and the laminator flange 2 is determined, and a value greater than or equal to the minimum distance is used as the safety distance. And in the operation after the safe distance is determined, the product to be laminated is placed within the safe distance for lamination, so that the qualification rate and the stability of the product are improved.
In step S5, the detection product with unqualified peel strength and cross-linking degree value and the corresponding position on the laminator can also be obtained, and the safety distance of the lamination formula can also be obtained. The evaluation method is suitable for evaluating various types of photovoltaic module laminating machines so as to ensure the stability of the photovoltaic module in the laminating process and improve the lamination qualification rate of the photovoltaic module.
The following are specific examples.
The method for testing the crosslinking degree comprises the following steps:
weighing a detection product, placing the detection product in a mesh bag, marking, placing the detection product in xylene at 140 ℃ for boiling and extracting for five hours, completely dissolving the non-crosslinked adhesive film in the xylene, and determining the crosslinking degree through the ratio of the sample amount not dissolved in the xylene to the total amount of an original sample, wherein the crosslinked adhesive film is not dissolved in the xylene after being crosslinked.
The method for testing the peeling degree comprises the following steps:
the peel strength characterizes the adhesive property between the adhesive film and the glass, and the peel strength between the adhesive film and the glass is carried out according to GB/T2790-1995 "180 DEG peel strength test method of adhesive". The instrument for testing the peeling strength is a universal electronic tensile machine with the model number of TH-8203A.
Examples
1. Three samples to be laminated were prepared;
2. respectively placing three laminated samples at distances of 1cm,3cm and 5cm from a laminating machine flange, and then laminating to respectively obtain laminated finished products numbered as No. 1, no. 2 and No. 3;
3. respectively cutting one sides of the three laminated finished products close to the flange of the laminating machine to cut strip-shaped detection articles with the width of 1cm, wherein the distance between each detection article and the flange 2 of the laminating machine can be seen in a table 1;
4. the strip-shaped test article was subjected to a test for peel strength value and crosslinking degree value, and the obtained experimental data are referred to table 1.
TABLE 1
From the test data in the table above, it can be seen that:
and when the distance between the detected product and the flange 2 of the laminating machine is more than or equal to 3cm, the peeling strength value is qualified. When the distance between the detected product and the laminator flange 2 is greater than or equal to 6cm, the cross-linking degree test value is qualified, so the safe laminating distance of the laminator edge is as follows: the distance between the detected product and the flange 2 of the laminating machine is more than or equal to 6cm, the product to be laminated can be placed in the area within the distance of more than or equal to 6cm from the flange 2 of the laminating machine, and the product is laminated in the area within the safe distance of the laminating machine, so that the qualification rate of the product is improved.
In one embodiment of the present invention, step S1 further includes cutting different types of test assemblies respectively to obtain a plurality of different types of samples to be laminated. For different types of photovoltaic modules with the same lamination parameters during lamination, the evaluation of the safety distance can be performed simultaneously. And respectively cutting different types of test components to obtain a plurality of different types of samples to be laminated, and marking. The same type identification and each sample identification to be laminated are carried out on a plurality of different types of samples to be laminated, namely, the samples can be distinguished according to the type of the samples and the samples of the same type.
Furthermore, a plurality of samples to be laminated of different types are placed at different positions of the flange of the laminating machine, the distance between the sample to be laminated of the same type and the flange of the laminating machine is unequal, and the distance between the sample to be laminated and the flange of the laminating machine is marked. As shown in fig. 4, in step S2, when several samples to be laminated are of different types, such as: the samples to be laminated comprise a first type of laminated sample 6a and a second type of laminated sample 7a, the first type of laminated sample 6a and the second type of laminated sample 7a are placed at different positions of a flange of a laminating machine, the first type of laminated sample 6a and the second type of laminated sample 7a can be alternately placed, the distance between the same type of sample to be laminated and the flange of the laminating machine is unequal, the samples to be laminated are marked, and the distance between the samples to be laminated and the flange of the laminating machine is marked.
The subsequent operations for the different types of samples to be laminated are identical to the evaluation method for the same type of samples to be laminated, and are not cumbersome here.
In an embodiment of the present invention, in step S3, a side of the laminated product close to the flange of the laminating machine is cut to obtain a plurality of detection articles and marked. Specifically, as shown in fig. 5, the plurality of laminated finished products include a first laminated finished product, a second laminated finished product, and a third laminated finished product, each of the first laminated finished product, the second laminated finished product, and the third laminated finished product is cut at a side close to the upper flange of the laminating machine, and after the cutting is completed, a first detected product 4a1 on the first laminated finished product, which is far away from the upper flange of the laminating machine, is adjacent to a second detected product 4b1 on the second laminated finished product, which is closest to the upper flange of the laminating machine, in the direction of the flange 2 of the laminating machine; it should be understood that: the extension line of the edge of the first test article 4a1 is collinear with the edge of the second test article 4b1 as shown in FIG. 5; or the extension line of the third test article 4b2 in the second laminated product is collinear with the fourth test article 4c 1. The method can quickly measure the safe distance from the detected product to the flange on the laminating machine, and reduce the repeated detection of the detected product with overlapped distance. Of course, the accuracy of the detection method in this embodiment will be reduced.
While the foregoing is directed to the preferred embodiment of the present invention, it will be appreciated by those skilled in the art that various changes and modifications may be made therein without departing from the principles of the invention as set forth in the appended claims.
