Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic module testing technology, and in particular to a photovoltaic module testing device. Background Technology
[0002] Manufacturing large photovoltaic modules for testing and verification is costly and time-consuming. Therefore, it is necessary to manufacture and verify small module samples before testing large module samples.
[0003] However, most companies' power testing machines are currently designed for testing large components of standard size. There is a lack of market research and development for power testing machines for small laminates. The existing fixing structure of the equipment cannot be adapted to small-sized laminates, and samples can only be fixed manually, resulting in low testing efficiency, poor stability and insufficient versatility.
[0004] Therefore, there is an urgent need to develop a testing device that can accurately and quickly test small components on a high-power testing machine, and can be adapted to small components of different sizes to verify the compatibility of component materials, thereby solving the problem of power testing of small components.

[0008] The mounting bracket is configured to detachably mount the photovoltaic module, positioning the photovoltaic module in the test position and facing the light source.
[0009] Individual test fixture, comprising:
[0010] A fixed frame, the outline of which is consistent with the photovoltaic module, so that it can replace the photovoltaic module in the test position of the mounting bracket;
[0011] An adjusting crossbar is adjustablely positioned within the fixed frame along the height direction of the fixed frame;
[0012] An adjusting vertical rod is adjustablely positioned within the fixed frame along its length.
[0013] The adjustable horizontal bar and the adjustable vertical bar intersect to form an adjustable test frame. The size of the test frame is adapted to different sizes of component units by adjusting the position of the adjustable horizontal bar and / or the adjustable vertical bar.

[0015] The adjusting vertical rod is detachably installed in the fixed frame through the first adjusting hole.
[0016] In one embodiment, a plurality of second adjustment holes are provided on the left and right sides of the fixed frame, and the second adjustment holes on the left and right sides of the fixed frame face each other along the length direction.
[0017] The adjusting crossbar is detachably installed in the fixed frame through the second adjusting hole.
[0018] In one embodiment, a reference vertical rod is also fixedly disposed inside the fixed frame, and the reference vertical rod is disposed at the middle part of the fixed frame along the length direction;
[0019] The reference vertical bar is configured to form the test frame together with the adjusting horizontal bar, the adjusting vertical bar, and the upper or lower border of the fixed frame.
[0020] In one embodiment, the reference vertical rod is located slightly to the right of the centerline of the fixed frame, and the adjusting horizontal rod and the first adjusting hole on the upper frame of the fixed frame are both located to the left of the reference vertical rod.
[0021] The reference vertical rod is located slightly to the left of the center line of the fixed frame, and the adjusting horizontal rod and the first adjusting hole on the upper frame of the fixed frame are both located to the right of the reference vertical rod.
[0022] In one embodiment, the adjusting crossbar is provided with at least one positive terminal hole and at least one negative terminal hole;
[0023] Both the positive electrode through hole and the negative electrode through hole are located on the side of the adjusting crossbar that has the first adjusting hole, and both are set adjacent to the reference vertical bar.
[0024] In one embodiment, a limiting structure is further provided within the test frame, the limiting structure being configured to limit the edge of the component unit.
[0025] In one embodiment, at least two of the corresponding side frames of the adjusting crossbar, the adjusting vertical bar, the reference vertical bar, and the fixed frame that form the test frame are provided with slots facing inwards towards the test frame, and the slots constitute the limiting structure.

[0029] Moreover, since the outline dimensions of the individual test frame are the same as those of the photovoltaic module, the individual test frame can be installed and positioned on the mounting bracket using the same positioning reference as the photovoltaic module, which improves installation efficiency and ensures positioning accuracy.
[0030] In addition, the adjustable characteristics of the horizontal and vertical bars allow the test frame size to be switched by moving the adjustment rods. This eliminates the need for frequent fixture changes or equipment recalibration. Simply adjusting the position of the adjustment rods is sufficient to quickly fix individual components of different sizes, significantly shortening test preparation time and improving experimental efficiency.

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0041] As described in the background section, existing power testing machines can usually only test large components of standard size and cannot be directly adapted to the testing of individual components. They require manual sample fixing and repeated adjustment and confirmation of the test position reference, resulting in low testing efficiency, poor stability and insufficient versatility.
[0042] To address this, this utility model provides a photovoltaic module testing device, which includes:
[0043] Light source 20;
[0044] Mounting bracket 50 is configured to detachably mount photovoltaic module 60, so that photovoltaic module 60 is in the test position and directly facing light source 20;
[0045] Individual test fixture 10, which includes:
[0046] The fixed frame 101 has the same outline dimensions as the photovoltaic module 60 so that it can replace the photovoltaic module 60 and be installed at the test position of the mounting bracket 50.
[0047] The adjusting crossbar 102 is adjustablely set in the fixed frame 101 along the height direction of the fixed frame 101;
[0048] The adjusting vertical rod 103 is adjustablely set in the fixing frame 101 along the length direction of the fixing frame 101;
[0049] The adjustable horizontal bar 102 and the adjustable vertical bar 103 intersect to form an adjustable test frame 104. The size of the test frame 104 is adapted to the component units 70 of different sizes by adjusting the position of the horizontal bar 102 and / or the vertical bar 103.
[0050] Photovoltaic module testing device according to an embodiment of the present invention:
[0051] See Figure 2 By mounting the photovoltaic module 60 on the mounting bracket 50, testing of the large-sized photovoltaic module 60 can be achieved;
[0052] See Figure 1 By replacing the photovoltaic module 60 with the individual test fixture 10, testing of small-sized individual modules 70 can be achieved.
[0053] In this way, the testing device, which was originally only applicable to standard-sized large components, is expanded into a universal testing platform that is compatible with individual components of different sizes (especially small-sized ones). This improves the universality of testing, solves the problems of poor adaptability, low efficiency, and insufficient stability in the existing technology when "large devices test small components", and reduces testing costs. It has significant practical value.
[0054] Moreover, since the outline dimensions of the individual test frame 10 are consistent with those of the photovoltaic module 60, the individual test frame 10 can be installed and positioned on the mounting bracket 50 using the same positioning reference as the photovoltaic module 60, which improves installation efficiency and ensures positioning accuracy.
[0055] In addition, by adjusting the adjustable characteristics of the horizontal bar 102 and the vertical bar 103, the size of the test frame 104 can be switched by moving the adjusting rod. There is no need to frequently change the fixture or recalibrate the equipment. Only the position of the adjusting rod needs to be adjusted to quickly fix the individual components 70 of different sizes, which significantly shortens the test preparation time and improves the experimental efficiency.
[0056] The photovoltaic module testing device provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0057] according to Figure 1 An exemplary photovoltaic module testing device according to at least one embodiment of the present invention is shown. The photovoltaic module testing device includes: a light source 20, a first light-blocking plate 30, a second light-blocking plate 40, and a mounting bracket 50.
[0058] Among them, the light source 20, the first light-blocking plate 30, the second light-blocking plate 40 and the mounting bracket 50 are all existing conventional technologies. Their structures will not be described in detail in this embodiment. Only their arrangement and function will be briefly described below.
[0059] For example, see Figure 1 The light source 20, the first light-blocking plate 30, the second light-blocking plate 40 and the mounting bracket 50 are arranged sequentially and alternately in the left and right direction. The interval between adjacent components can be set according to the test requirements.
[0060] Among them, the light source 20 is a sunlight simulation component, used to provide simulated sunlight that meets the A+ level requirements specified in IEC 60904-9:202. Specifically, it can be selected from existing sunlight simulators.
[0061] Both the first light-blocking plate 30 and the second light-blocking plate 40 are plates with light-transmitting openings, used to physically block ambient light and reduce scattering and reflection, ensuring that the lighting conditions in the test area are provided solely by the sunlight simulator and suppressing ambient light interference. The size of the light-transmitting opening of the second light-blocking plate 40 can be larger or smaller than that of the first light-blocking plate 30.
[0062] The mounting bracket 50 is used to fix the photovoltaic module 60 under test, placing it in the test position so that it faces the light source 20 directly for simulated sunlight irradiation testing. It should be understood that the photovoltaic module 60 under test here typically refers to a standard-sized large module.
[0063] See Figure 2 In one example, the mounting bracket 50 may include two columns and a frame fixed to the two columns. The dimensions of the frame are designed to match the dimensions of the photovoltaic module 60 under test. For example, the edges of the frame may be aligned with the edges of the photovoltaic module 60 under test to facilitate rapid positioning and installation. Specifically, the photovoltaic module 60 under test may be fixedly positioned on the frame using snap-fit or other methods.
[0064] It should be understood that a test instrument (not shown in the figure) that is electrically connected to the photovoltaic module 60 under test is also provided on one side of the mounting bracket 50 for power testing of the photovoltaic module 60, etc. This is a conventional technology and will not be described in detail here.
[0065] Based on the above, see Figure 2 When testing a large-size photovoltaic module 60, fix the photovoltaic module 60 to be tested on the test position of the mounting bracket 50, then adjust the test parameters and turn on the corresponding equipment to realize the test of the large-size photovoltaic module 60.
[0066] However, in the existing technology, due to the long testing cycle and high cost of large-size photovoltaic modules 60, it is often necessary to test the individual module units 70 in the large-size photovoltaic modules 60 in advance. However, since the mounting bracket 50 is usually only suitable for the installation of standard-sized large modules, it cannot be used for the installation of small-sized individual module units 70. This results in the testing device not being directly compatible with the performance testing of individual module units 70, requiring manual fixing or replacement of the dedicated mounting bracket 50, which leads to low testing efficiency.
[0067] Among them, the module unit 70 can be understood as a small-sized photovoltaic module with a size smaller than that of the large-sized photovoltaic module 60, which is also composed of photovoltaic glass, solar cells, encapsulant film and busbars.
[0068] To address the aforementioned issues, this photovoltaic module testing device also includes a single-unit testing frame 10. The single-unit testing frame 10 is used to fix the small-sized module 70 to be tested and can replace the large-sized photovoltaic module 60 for quick installation on the mounting bracket 50. This expands the testing device, which was originally only applicable to standard-sized large modules, into a universal testing platform compatible with module 70s of different sizes, thus solving the problem of poor adaptability in the prior art when "large devices test small modules".
[0069] For details, see Figure 3 In this embodiment, the single-unit test frame 10 includes a fixed frame 101, an adjusting horizontal bar 102, and an adjusting vertical bar 103.
[0070] Among them, the fixed frame 101 is the positioning support frame of the single unit test frame 10, which is used to position and install on the mounting bracket 50, providing a basis for the installation and positioning of the small-sized component unit 70.
[0071] Specifically, in this embodiment, the fixed frame 101 is a frame structure with the same outline size as the aforementioned large-size photovoltaic module 60 to be tested, so that it can replace the photovoltaic module 60 and be directly installed on the test position of the mounting bracket 50. Moreover, the fixed frame 101 can be quickly positioned using the same positioning reference as the large-size photovoltaic module 60, thereby improving installation efficiency and ensuring positioning accuracy.
[0072] It should be understood that the mounting bracket 50 can typically be adapted to the installation of one or more photovoltaic modules 60 of different sizes. Accordingly, in this embodiment, the outline dimensions of the fixing frame 101 can be consistent with the outline dimensions of one of the photovoltaic modules 60 of different sizes.
[0073] For example, see Figure 2 and Figure 3Corresponding to the rectangular shape of the photovoltaic module 60, the fixing frame 101 is also set to a rectangular shape, and the outline dimensions are corresponding. Accordingly, the fixing frame 101 includes a longer upper and lower frame and a relatively shorter left and right frame.
[0074] In this embodiment, the fixing frame 101 can be fixed to the mounting bracket 50 by means of snap-fit, bolt connection or other methods, preferably bolt connection, which can improve the installation stability of the fixing frame 101.
[0075] See Figure 3 and Figure 4 The adjusting horizontal bar 102 is arranged horizontally in the fixed frame 101, and the adjusting vertical bar 103 is arranged vertically in the fixed frame 101. The adjusting horizontal bar 102 and the adjusting vertical bar 103 intersect each other in the fixed frame 101 to form a test frame 104. The test frame 104 can be used to install small-sized component units 70. In this way, small-sized component units 70 can be installed on the unit test frame 10 through the test frame 104, and then fixed on the mounting bracket 50, achieving the purpose of "testing small components with large devices".
[0076] Specifically, the test frame 104 can be formed by the combination of the adjusting horizontal bar 102, the adjusting vertical bar 103 and the frame of the fixed frame 101, or it can be formed by the combination of multiple adjusting horizontal bars 102 and adjusting vertical bars 103 themselves.
[0077] For example, see Figure 4 When there is one adjusting horizontal bar 102 and one adjusting vertical bar 103, the test frame 104 is formed by the combination of two of the adjusting horizontal bar 102, the adjusting vertical bar 103 and the two side frames of the fixed frame 101.
[0078] For example, see Figure 5 When there are two or more adjusting horizontal bars 102 and adjusting vertical bars 103, the test frame 104 can be formed by combining each adjusting horizontal bar 102 and each adjusting vertical bar 103.
[0079] In this embodiment, it is preferable that the number of adjusting horizontal bars 102 and adjusting vertical bars 103 is one each. In this way, by using the frame of the test frame 104 itself to form the test frame 104, the number of horizontal bars and vertical bars can be reduced, the complexity of the single test frame 10 can be reduced, and the cost can be reduced.
[0080] In this embodiment, both the adjusting horizontal bar 102 and the adjusting vertical bar 103 are adjustablely disposed within the fixed frame 101. For example, the adjusting horizontal bar 102 is adjustablely disposed within the fixed frame 101 along the height direction, and the adjusting vertical bar 103 is adjustablely disposed within the fixed frame 101 along the length direction. This arrangement allows for adjustment of the size of the enclosed test frame 104 by adjusting the position of the adjusting horizontal bar 102 and / or the adjusting vertical bar 103 within the fixed frame 101, thereby accommodating component units 70 of different sizes and improving versatility.
[0081] For example, corresponding to Figure 3 The single test frame 10 shown can be widened by adjusting the vertical rod 103 to the right and narrowed by adjusting it to the left; the height of the test frame 104 can be increased by adjusting the horizontal rod 102 upward and narrowed by adjusting it downward.
[0082] For details, see Figure 3 In this embodiment, both the adjusting crossbar 102 and the upper frame of the fixing frame 101 are provided with a plurality of first adjusting holes 105. The first adjusting holes 105 are arranged at intervals along the length direction, and the first adjusting holes 105 on the upper frame of the adjusting crossbar 102 and the fixing frame 101 are aligned with each other along the height direction. Thus, when installing the adjusting vertical bar 103, the adjusting vertical bar 103 is passed through the first adjusting holes 105 on the upper frame and the adjusting crossbar 102 from top to bottom until the lower end of the adjusting vertical bar 103 abuts against the lower frame, thereby achieving the installation and positioning of the adjusting vertical bar 103; when it is necessary to adjust the width of the test frame 104, the first adjusting hole 105 into which the adjusting vertical bar 103 is inserted is switched.
[0083] See Figure 3 The left and right sides of the fixed frame 101 are each provided with a plurality of second adjustment holes 106, which are spaced apart along the height direction and aligned along the length direction. Thus, when installing the adjusting crossbar 102, it is horizontally inserted into the corresponding second adjustment hole 106 on the left and right sides of the fixed frame 101 to achieve the installation and positioning of the adjusting crossbar 102; when it is necessary to adjust the height of the test frame 104, simply switch the second adjustment hole 106 into which the adjusting crossbar 102 is inserted.
[0084] In some specific examples, by adjusting the positions of the horizontal bar 102 and the vertical bar 103, test frames 104 of at least the following sizes can be formed within the fixed frame 101, such as 300mm×300mm, 300mm×400mm, 300mm×450mm, etc., that is, the length × width dimensions. These sizes are all commonly used small photovoltaic modules on the market. Therefore, forming test frames 104 of the above sizes on the single-unit test frame 10 can facilitate the testing of commonly used single-unit modules 70, improving its convenience.
[0085] Furthermore, both the adjusting horizontal bar 102 and the adjusting vertical bar 103 can be fixed to the fixed frame 101 using fasteners, specifically bolts. This fasteners secure the dimensions of the test frame 104, ensuring its stability. For example, after the adjusting horizontal bar 102 and the adjusting vertical bar 103 are adjusted to their positions, bolts can be used to fix both ends of the adjusting horizontal bar 102 to the left and right sides of the fixed frame 101, and the upper end and middle part of the adjusting vertical bar 103 can be fixed to the upper frame of the fixed frame 101 and the adjusting horizontal bar 102, respectively.
[0086] Further, see Figure 3 A reference vertical rod 107 is also fixedly installed inside the fixed frame 101. The reference vertical rod 107 is also arranged vertically and is located in the middle of the fixed frame 101 along its length. With this arrangement, the reference vertical rod 107 can be used as one of the side frames of the test frame 104. Since the reference vertical rod 107 is located in the middle of the fixed frame 101, when the reference vertical rod 107, the adjusting horizontal rod 102, the adjusting vertical rod 103, and the upper or lower side frame of the fixed frame 101 form the test frame 104, the test frame 104 can be located in the middle of the fixed frame 101. This allows the component 70 positioned in the test frame 104 to be directly aligned with the light source 20, reducing the need for adjustments to the light path and improving efficiency.
[0087] Accordingly, in this embodiment, a second adjustment hole 106 is also provided on the reference vertical rod 107 to facilitate the passage of the adjustment horizontal rod 102.
[0088] Furthermore, in this embodiment, the reference vertical rod 107 is located to the right or to the left of the center line of the fixed frame 101.
[0089] When the reference vertical rod 107 is located slightly to the right of the centerline of the fixed frame 101, the adjusting horizontal rod 102 and the first adjusting hole 105 on the upper frame of the fixed frame 101 are both located to the left of the reference vertical rod 107. The centerline can be understood as the exact center of the fixed frame 101 along its length. With this configuration, since the reference vertical rod 107 is slightly to the right of the centerline of the fixed frame 101, the resulting test frame 104 is positioned precisely in the middle of the fixed frame 101, which facilitates direct alignment of the component unit 70 within the test frame 104 with the light source 20.
[0090] Similarly, see Figure 3 When the reference vertical rod 107 is located slightly to the left of the center line of the fixed frame 101, the adjusting horizontal rod 102 and the first adjusting hole 105 on the upper frame of the fixed frame 101 are both located to the right of the reference vertical rod 107. With this configuration, since the reference vertical rod 107 is positioned slightly to the left of the center line of the fixed frame 101, the resulting test frame 104 can be positioned in the middle of the fixed frame 101, which facilitates the direct alignment of the component unit 70 within the test frame 104 with the light source 20.
[0091] In this embodiment, the adjusting crossbar 102 is provided with at least one positive terminal through hole 108 and at least one negative terminal through hole 109, for example, Figure 3 An exemplary embodiment is shown in which there is one positive electrode through-hole 108 and one negative electrode through-hole 109. The positive electrode through-hole 108 is used for the positive electrode lead of the component unit 70 to pass through, and the negative electrode through-hole 109 is used for the negative electrode lead of the component unit 70 to pass through, so as to facilitate connection with testing instruments.
[0092] Furthermore, corresponding to the reference vertical rod 107 that is offset from the centerline of the fixed frame 101, in this embodiment, both the positive electrode through hole 108 and the negative electrode through hole 109 are located on the side of the adjusting crossbar 102 that has the first adjusting hole 105. For example, in Figure 3 In the test frame 104, the reference vertical rod 107 is set slightly to the left. Therefore, the first adjustment hole 105, the positive electrode wire hole 108, and the negative electrode wire hole 109 are all located on the right side of the reference vertical rod 107, so as to ensure that the positive electrode wire hole 108 and the negative electrode wire hole 109 are all located within the test frame 104.
[0093] Accordingly, see Figure 3 The positive electrode through hole 108 and the negative electrode through hole 109 are both located near the reference vertical rod 107. Thus, when the reference vertical rod 107 forms the frame of the test frame 104, the positive electrode through hole 108 and the negative electrode through hole 109 can be located at least within the test frame 104, ensuring the lead-out of the positive and negative electrodes of the component unit 70.
[0094] Furthermore, in this embodiment, a limiting structure is also provided on the test frame 104. The limiting structure is configured to limit the edge of the component unit 70 to achieve the limiting of the component unit 70 within the test frame 104, thereby ensuring the positioning stability and accuracy of the component unit 70.
[0095] Specifically, in this embodiment, at least two of the corresponding side frames of the adjusting horizontal bar 102, adjusting vertical bar 103, reference vertical bar 107, and fixing frame 101 that form the test frame 104 are provided with slots 110 facing inwards towards the test frame 104. The slots 110 facing inwards towards the test frame 104 can be understood as the openings of the slots 110 facing the center of the test frame 104, for example, in... Figure 3 In the aforementioned orientation, the slot 110 of the adjusting horizontal bar 102 is open downwards, and the slot 110 of the reference vertical bar 107 is open to the right. Thus, by engaging and limiting the component unit 70 through at least two slots 110, the positioning stability and accuracy of the component unit 70 can be ensured.
[0096] For example, see Figure 3 In one example, the reference vertical rod 107, the adjusting horizontal rod 102, and the adjusting vertical rod 103 are all provided with slots 110, and the width of the slots 110 is slightly larger than the thickness of the component unit 70. Thus, when installing the component unit 70, the adjusting vertical rod 103 is removed beforehand, and then the component unit 70 is inserted into the slots 110 of the reference vertical rod 107 and the adjusting horizontal rod 102 to achieve pre-positioning of the component unit 70. Then, the adjusting vertical rod 103 is inserted into the fixing frame 101 through the corresponding first adjusting hole 105, ensuring that the slot 110 of the adjusting vertical rod 103 is opposite to the edge of the component unit 70. This ensures that when the adjusting vertical rod 103 is installed in place, the edge of the component unit 70 is precisely inserted into the slot 110 of the adjusting vertical rod 103. The three slots 110 limit the edge of the component unit 70, enabling accurate positioning and limiting of the component unit 70 within the test frame 104.
[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.
[0098] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
