[0002] As an important part of photovoltaic modules, the sealing silicone plays roles such as sealing to prevent water vapor from entering from the edges of the module, bonding the frame for fixing the aluminum frame, and bonding and fixing the junction box. Due to different application scenarios of photovoltaic modules, different requirements are put forward for the performance of the silicone. In order to test the performance of the sealant and better apply it to photovoltaic modules, performance testing and reliability testing of the sealant are required.

[0003] To ensure the quality of the sealant, when conducting performance testing, different performances of the sealant need to be tested separately, and test samples of different thicknesses are required for testing different performances of the sealant. However, since most of the existing sample preparation devices are special devices and cannot meet the need for preparing samples of different thicknesses, it is necessary to design multiple different sample preparation devices to prepare samples of different thicknesses. In this way, there will be a large number of devices and the sample preparation cost will be relatively high. In addition, when the existing sample preparation devices prepare samples, the sealant is prone to sticking, resulting in the sample preparation device being difficult to clean, the test samples being difficult to demold, being easily damaged during demolding, and air bubbles being easily generated on the surface of the test samples, which affects the test accuracy of the sealant. Summary of the Utility Model

[0004] Based on this, the present utility model provides a sample preparation device for a sealant used in photovoltaic modules to solve the problems of poor versatility and low test accuracy of the existing sample preparation devices.

[0030] An embodiment of the present utility model provides a sample preparation device for a sealant used in a photovoltaic module, which includes a bottom plate 1, an extrusion member 2, and an adjustment mechanism 3;

[0031] The bottom plate 1 has a horizontal first surface 101, and an isolation film 4 for containing and covering the sealant is laid on the first surface 101;

[0032] The extrusion member 2 is horizontally arranged on the adjustment mechanism 3 and is located directly above the first surface 101, and the bottom of the extrusion member 2 is parallel to the first surface 101;

[0033] The adjustment mechanism 3 is arranged on the bottom plate 1 to adjust the height of the extrusion member 2 in a direction perpendicular to the first surface 101, so as to adjust the vertical distance between the extrusion member 2 and the first surface 101;

[0034] The isolation film 4 and / or the extrusion member 2 can move in a horizontal direction parallel to the first surface 101, so that the extrusion member 2 can move relative to the sealant placed on the isolation film 4.

[0035] When this sample preparation device is in use, the sealant 7 is extruded onto the isolation film 4 on the first surface 101 of the bottom plate 1, and an isolation film 4 is covered on the upper side of the sealant 7. Then, the height of the extrusion member 2 is adjusted by the adjustment mechanism 3 so that the distance between the extrusion member 2 and the first surface 101 is equal to the thickness of the required sealant test sample. Then, the isolation film 4 or the extrusion member 2 is moved in a horizontal direction parallel to the first surface 101, so that the extrusion member 2 moves relative to the sealant 7. When the extrusion member 2 contacts the sealant 7, the extrusion member 2 will extrude the sealant 7 to form a test sample with a standard thickness. After solidification, the sealant 7 can be removed from the isolation film 4.

[0036] By setting the isolation film 4, this solution can not only isolate the sealant 7 from the bottom plate 1 and the extrusion part 2, avoiding the adhesion of the sealant 7 to the bottom plate 1 and the extrusion part 2, making the sample preparation equipment easier to clean, and the sealant sample easier to remove, with more convenient operation. Moreover, during the extrusion of the sealant 7, the extrusion part 2 can squeeze out the air between the upper side of the sealant 7 and the isolation film 4 through the extrusion of the isolation film 4, making the upper side of the sealant 7 basically isolated from the air, thereby avoiding the generation of bubbles on the surface of the prepared test sample, making the quality of the test sample better, and improving the test accuracy of the test sample. By setting the adjustment mechanism 3, the thickness of the prepared sealant sample can be freely controlled, with better versatility, greatly increasing the accuracy and convenience of the test data of the sealant 7.

[0037] The following will provide a detailed description of the sample preparation equipment for the sealant used in the photovoltaic module provided by the embodiment of the present invention with reference to the accompanying drawings.

[0038] Figure 1 It is a schematic structural diagram of the sample preparation equipment provided by at least one embodiment of the present invention. Refer to Figure 1 The sample preparation equipment includes a bottom plate 1, an adjustment mechanism 3, and an extrusion part 2.

[0039] In this embodiment, the bottom plate 1 is used to carry the sealant 7 so that the extrusion part 2 can extrude the sealant 7 on the bottom plate 1 into a test sample with a standard thickness. Specifically, refer to Figure 1 In this embodiment, the bottom plate 1 is a rectangular flat plate, and the upper surface of the rectangular flat plate is the first surface 101, and the first surface 101 is in a horizontal state. In this way, when the sealant 7 is placed on the first surface 101 of the bottom plate 1, the extrusion part 2 extrudes the sealant 7, enabling the sealant 7 to horizontally extend along the first surface 101, thereby obtaining a sealant test sample with a uniform thickness and ensuring the quality of the test sample. Of course, in some other embodiments, the shape of the bottom plate 1 can also be circular, diamond-shaped, or other regular and irregular shapes, and this embodiment does not limit this.

[0040] Refer to Figure 1, in this embodiment, an isolation film 4 is laid on the first surface 101 of the bottom plate 1. The isolation film 4 is used to hold and cover the sealant 7, so as to isolate the sealant 7 and the bottom plate 1 from the extrusion member 2 through the isolation film 4. Thereby, when the sealant 7 is placed on the bottom plate 1, adhesion between the sealant 7 and the bottom plate 1 can be avoided, and when the extrusion member 2 extrudes the sealant 7, adhesion between the extrusion member 2 and the sealant 7 can also be avoided, making the sample preparation equipment easier to clean, and the sealant test sample easier to demold and remove, and the operation is more convenient. Moreover, during the process of the extrusion member 2 extruding the sealant 7, the extrusion member 2 can squeeze out the air between the upper side of the sealant 7 and the isolation film 4 by extruding the isolation film 4, so that the upper side of the sealant 7 is basically isolated from the air, thereby avoiding the generation of bubbles on the surface of the prepared test sample, making the quality of the test sample better, and improving the test accuracy of the test sample.

[0041] In a specific example, the isolation film 4 can be set as two separated upper and lower layers (not shown in the figure). The lower isolation film 4 is used to hold the sealant 7 to isolate the bottom plate 1 from the sealant 7, and the upper isolation film 4 is used to cover the sealant 7 to isolate the sealant 7 and the extrusion member 2 from the air.

[0042] In another embodiment, the isolation film 4 can also be set as one layer. After the sealant 7 is placed at a specified position of the isolation film 4, the remaining part of the isolation film 4 can be covered on the sealant 7 by folding, so as to carry and cover the sealant 7 through one isolation film 4.

[0043] In this embodiment, the isolation film 4 can be fixedly arranged on the first surface 101 or movably arranged on the first surface 101. Specifically, when the extrusion member 2 is fixedly arranged in the horizontal direction, the isolation film 4 is movably arranged on the first surface 101. For example, the isolation film 4 is freely laid on the first surface 101. In this way, when preparing the test sample, the isolation film 4 can be moved along the first surface 101 by dragging, and then the sealant 7 is dragged through the extrusion member 2 to be extruded and formed. It should be noted that when the isolation film 4 has two layers, it is the lower isolation film 4 that is dragged.

[0044] When the extrusion member 2 is movably arranged in the horizontal direction, the isolation film 4 can be fixedly or movably arranged on the first surface 101. For example, the isolation film 4 is pasted and fixed or freely laid on the first surface 101. In this way, when preparing the test sample, the isolation film 4 remains stationary on the first surface 101, and the relative movement between the extrusion member 2 and the sealant 7 can be achieved by moving the extrusion member 2, so as to realize the extrusion of the sealant 7. It should be noted that in the case where the isolation film 4 is fixed to the first surface 101, when the isolation film 4 has two layers, only the lower isolation film 4 is pasted and fixed to the first surface 101, and when the isolation film 4 is a single layer, only a part of the isolation film 4 is pasted and fixed to the first surface 101.

[0045] Further, in this embodiment, the isolation film 4 is preferably made of a material that does not have adhesiveness to the sealant 7. For example, the isolation film 4 can be selected as a release film or a Teflon cloth. In this way, the prepared sealant test sample can be quickly peeled off from the isolation film 4, the operation is more convenient, and the test sample will not be damaged during peeling due to its adhesiveness, ensuring the integrity of the test sample.

[0046] In this embodiment, the adjusting mechanism 3 is used to support the pressing member 2 and can adjust the height of the pressing member 2 in a direction perpendicular to the first surface 101 to adjust the vertical distance between the pressing member 2 and the first surface 101. In this way, the distance between the pressing member 2 and the first surface 101 can be adjusted to exactly equal the thickness of the required sealant test sample, so as to obtain a test sample with a specified thickness. By this method, the thickness of the prepared sealant sample can be freely controlled, and the versatility is better, greatly improving the convenience of testing the sealant 7.

[0047] See Figure 1 , in this embodiment, the adjusting mechanism 3 includes a support column 301 vertically arranged on the bottom plate 1 and an adjusting member 302 arranged on the support column 301 in a vertically adjustable manner, and the pressing member 2 is arranged on the adjusting member 302. In this way, when the adjusting member 302 moves up and down along the support column 301, it can drive the pressing member 2 to move up and down, thereby adjusting the height of the pressing member 2.

[0048] For example, see Figure 1 , in this embodiment, the support column 301 can specifically be a rectangular column, and the adjusting member 302 is a sliding clamp that clamps on the support column 301. Among them, the sliding clamp is made of a material with a certain elasticity, such as plastic, so that when the sliding clamp moves up and down along the support column 301, it can use its own elasticity to tightly hold the support column 301 to lock the position, and further realize the stable support of the pressing member 2.

[0049] Further, see Figure 2 , a scale 6 is arranged on the support column 301. Through the scale 6, the height of the adjusting member 302 can be calibrated, so as to determine the height of the pressing member 2, making the thickness control of the test sample more refined and accurate.

[0050] Of course, in some other embodiments, the adjusting mechanism 3 can also be selected as an existing adjustable support foot or the like.

[0051] In some embodiments, the extrusion member 2 is fixedly connected to the adjusting member 302 so that it cannot move in the horizontal direction. For example, one end of the extrusion member 2 can be fixed to the adjusting member 302 by means of snap connection, bolt connection, integral molding, etc., and the bottom of the extrusion member 2 is arranged parallel to the first surface 101 of the bottom plate 1. With such a setting, when preparing the sealant test sample, after placing the sealant 7 on the first surface 101, dragging the isolation film 4 in the horizontal direction perpendicular to the extrusion member 2 can drive the sealant 7 to pass through the extrusion member 2, and the fixedly arranged extrusion member 2 is used to extrude the sealant 7 into a test sample with a standard thickness.

[0052] Furthermore, to improve the support stability of the extrusion member 2, referring to Figure 1 , in this embodiment, two support columns 301 are provided, and the extrusion member 2 is fixedly connected between the adjusting members 302 on the two support columns 301, and the bottom of the extrusion member 2 is parallel to the first surface 101. In this way, the extrusion member 2 can be supported by the two support columns 301 and the adjusting member 302, which can improve the installation stability of the extrusion member 2 to facilitate the extrusion of the sealant 7 by the extrusion member 2.

[0053] More specifically, referring to Figure 1 , in this embodiment, along the width direction of the bottom plate 1, the two support columns 301 are arranged side by side on both sides of the first surface 101, and along the length direction of the bottom plate 1, the two support columns 301 are located in the middle of the first surface 101. With such a setting, the extrusion member 2 is centered directly above the bottom plate 1, which is more convenient for the extrusion operation of the sealant 7. Of course, in other embodiments, the positions of the two support columns 301 can be other, for example, the two support columns 301 are arranged side by side along the length direction of the bottom plate 1 or in a direction inclined to the length direction, for example, the two support columns 301 are arranged side by side at the front end or the rear end of the bottom plate 1 along the length direction, etc.

[0054] Referring to Figure 3 , based on the sample preparation device with the extrusion member 2 fixedly arranged, when preparing the sealant test sample, after placing the sealant 7 on the isolation film 4 on the first surface 101, then covering the isolation film 4 on the upper side of the sealant 7, and then dragging the isolation film 4 in the horizontal direction perpendicular to the extrusion member 2, that is, the length direction of the bottom plate, until the sealant 7 completely passes through the extrusion member 2. During the contact between the sealant 7 and the extrusion member 2, the extrusion member 2 will extrude the sealant 7 into a test sample with a standard thickness.

[0055] In some other embodiments, the extrusion member 2 is horizontally movably arranged on the adjusting mechanism 3. For example, referring to Figure 4, a guiding mechanism 5 extending in the horizontal direction is fixedly arranged on the adjusting member 302, and the pressing member 2 is movably arranged on the guiding mechanism 5, and the bottom of the pressing member 2 is arranged in parallel with the first surface 101 of the bottom plate 1. With such an arrangement, when preparing the sealant test sample, after placing the sealant 7 on the first surface 101, the pressing member 2 is driven to move along the guiding mechanism 5, and when the pressing member 2 passes through the sealant 7, the sealant 7 can be extruded into a test sample with a standard thickness.

[0056] Further, to improve the moving stability of the pressing member 2, referring to Figure 4 , in this embodiment, the guiding mechanisms 5 can be arranged in two rows side by side. For example, in some embodiments, there are two supporting columns 301, and the guiding mechanisms 5 are arranged on the adjusting members 302 of the two supporting columns 301, and the two ends of the pressing member 2 are movably engaged with the two guiding mechanisms 5 respectively. In this way, guiding the movement of the pressing member 2 through the two guiding mechanisms 5 can not only improve the moving stability of the pressing member 2, but also improve the supporting stability of the pressing member 2, thereby improving the extrusion effect of the pressing member 2 on the sealant 7.

[0057] In some specific examples, the guiding mechanism 5 can be a slide rail (not shown in the figure) fixedly connected to the adjusting member 302, and the pressing member 2 is slidably mounted on the slide rail through a slide seat. In this way, driving the slide seat to slide along the slide rail can achieve the horizontal movement of the pressing member 2.

[0058] And in this embodiment, referring to Figure 4 , the guiding mechanism 5 includes two horizontal plates 501 arranged opposite to each other up and down, and a guiding groove is formed between the two horizontal plates 501. The width of the guiding groove is equal to or slightly larger than the thickness of the pressing member 2, so that the pressing member 2 can extend into the guiding groove and move horizontally along the guiding groove. With such an arrangement, the structure of the guiding mechanism 5 is simpler, which can reduce the equipment cost and is also convenient for the disassembly of the pressing member 2, providing a basis for the rapid cleaning and replacement of the pressing member 2.

[0059] Further, based on the structural design that the guiding mechanism 5 includes two horizontal plates 501, in order to ensure the structural stability of the guiding mechanism 5, in this embodiment, a plurality of supporting columns 301 can be arranged to support the guiding mechanism 5. For example, referring to Figure 4 , there are four supporting columns 301, and the four supporting columns 301 are respectively arranged at the four corners of the bottom plate 1. The four supporting columns 301 are divided into two rows side by side along the first direction, where the first direction can be understood as the length direction of the bottom plate. Two horizontal plates 501 are connected between the adjusting members 302 of the two supporting columns 301 in each group, thereby forming two guiding mechanisms 5 arranged side by side.

[0060] Referring to Figure 5, a sample preparation device movably arranged based on the above-mentioned extrusion member 2. When preparing a sealant test sample, after placing the sealant 7 on the release film 4 on the first surface 101, another release film 4 is covered on the upper side of the sealant 7, and then the extrusion member 2 is driven to move along the guiding mechanism 5 until the extrusion member 2 completely passes through the sealant 7. During the contact between the sealant 7 and the extrusion member 2, the extrusion member 2 will extrude the sealant 7 into a test sample with a standard thickness.

[0061] In this embodiment, the extrusion member 2 is used to extrude the sealant 7 to form a test sample with a standard thickness. To ensure the uniform thickness of the test sample, the bottom side of the extrusion member 2 where it extrudes the sealant 7 should be parallel to the first surface 101 of the bottom plate 1. For example, referring to Figure 1 and Figure 4 , the extrusion member 2 can be a straight circular rod. When the circular rod is installed on the adjusting member 302 or the guiding mechanism 5, the circular rod is in a horizontal state and can be used to extrude the sealant 7. Of course, in some other embodiments, the extrusion member 2 can also be a flat plate, a square rod, etc.

[0062] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0063] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
