Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic component testing, and in particular to testing tools and testing systems. Background Art

[0002] Solar energy resources are abundant and widely distributed. As global energy shortages and environmental pollution become increasingly prominent, solar photovoltaic power generation has become an emerging industry that is widely concerned and focused on by countries around the world due to its clean, safe, convenient and efficient characteristics. Against this background, the global photovoltaic power generation industry has grown rapidly, the industry scale has continued to expand, and product costs have continued to decline.

[0003] The most important issue for photovoltaic modules is power. Since photovoltaic glass can use its ultra-high transmittance to provide light energy for the battery cell, the photovoltaic glass is placed on the outermost layer on the front of the module to directly receive sunlight in an outdoor environment, so that the photovoltaic module can achieve high power output. Due to different customer demand scenarios, the frames of various types of modules are also different. The frame of a photovoltaic module includes a cavity surrounded by multiple supporting edges and a fixing groove formed by the clamping edge and the cavity. The fixing groove is used to clamp the laminate. The edge of the supporting edge facing away from the fixing groove that extends toward one side of the laminate is called the C edge. Some photovoltaic modules have no C edge in the frame and the supporting edge is arc-shaped, and the arc protrudes toward one side of the laminate.

[0004] Traditionally, when testing photovoltaic modules with no C-edge, suction cups are usually used to attach to the photovoltaic modules. However, due to the particularity of photovoltaic modules with curved frames without C-edge, suction cups can only be used for double-glass photovoltaic modules with curved frames without C-edge. When the curved frame of the photovoltaic module is a single-glass photovoltaic module with no C-edge, using suction cups to install and fix this photovoltaic module is prone to hidden cracks. Utility Model Content

[0005] Based on this, it is necessary to provide a test tool and a test system.

[0006] The disclosed embodiment provides a test jig for installing and testing photovoltaic modules. The photovoltaic modules include a laminate and a single-glass arc-shaped frame without a C-edge. The arc-shaped frame includes two support bars arranged back to back and extending back to the laminate respectively. The test jig includes a jig body, a test assembly and two fixing members. The jig body includes a first end and a second end facing each other along a first direction. The test assembly is connected to the jig body. Each fixing member includes a fixing portion, a bending portion and a clamping portion connected in sequence. The fixing portion extends along the first direction. The two fixing portions are respectively connected to the first end and the second end. The bending direction of the bending portion is perpendicular to the first direction. The clamping portion is located on the side of the bending portion facing the fixing portion along the first direction. The clamping portion extends along the first direction. The fixing portion, the bending portion and the clamping portion form a clamping groove; the two clamping grooves are arranged opposite to each other along the first direction; the two clamping grooves are used to clamp two support bars placed opposite to each other along the first direction.

[0007] In the test fixture provided by the embodiment of the present disclosure, the fixing parts, the bending parts and the clamping parts of the two fixing parts respectively form two clamping grooves, and the two clamping grooves are arranged opposite to each other along the first direction, and can clamp two support bars of the arc-shaped frame without C-edge arranged opposite to each other along the first direction. The test fixture is not prone to hidden crack problems when installing and fixing a single-glass arc-shaped frame without C-edge photovoltaic module.

[0008] In some embodiments, the materials of the two fixing members are both polyoxymethylene resin.

[0009] Polyoxymethylene resin has high tensile strength and rigidity, can bear large loads, and is easy to fix and flip photovoltaic modules. It also has good friction resistance and wear resistance and is not easy to damage.

[0010] In some embodiments, the test fixture further includes a spring assembly, which includes a movable end, a spring, and a fixed end connected in sequence along a first direction, the movable end is connected to the second end, and the fixed end is connected to a fixed portion of one of the two fixing members.

[0011] With such an arrangement, the spring assembly can adjust the distance between the two fixings, which is conducive to the use of the test tooling on photovoltaic modules of different sizes, and is also convenient for the installation and removal of the photovoltaic modules. The elastic effect of the spring assembly can avoid deformation of the frame of the photovoltaic module.

[0012] In some embodiments, the movable end is provided with a movable track extending along a first direction, and the spring assembly also includes a guide column, and the spring is sleeved on the guide column; along the first direction, one end of the guide column is fixed to a fixed portion of a fixing member, and the other end of the guide column can be movably located on the movable track.

[0013] With such arrangement, when the spring is extended and retracted along the first direction, the guide post can follow the spring to move in the movable track, thereby ensuring the stretching effect of the spring while enabling the spring to be accurately reset.

[0014] In some embodiments, the spring is connected to the movable end by welding, and the spring is connected to the fixed end by welding.

[0015] With such an arrangement, the welding connection strength is high, which prevents the spring from being separated from the movable end and the fixed end when expanding and contracting, thereby causing damage to the photovoltaic module.

[0016] In some embodiments, the connection between the one fixing member and the guide column is a bolt connection.

[0017] Such an arrangement improves the connection stability between the fixing piece and the guide post, making it difficult for the guide post to separate from the fixing piece.

[0018] In some embodiments, the test assembly includes a test body and a plurality of copper sheets. The test body is provided with a plurality of mounting slots, the plurality of mounting slots are arranged in parallel along a first direction, and the plurality of copper sheets are mounted in the plurality of mounting slots in a one-to-one correspondence.

[0019] With such arrangement, the installation slot improves the installation stability of the copper sheet. By contacting the copper sheet for power detection, manual operation steps are reduced and the test power stability is improved.

[0020] In some of the embodiments, the test assembly further includes a positive terminal and a negative terminal, the positive terminal and the negative terminal are electrically connected to the copper sheet, and the positive terminal and the negative terminal are used to be electrically connected to the photovoltaic assembly.

[0021] With this arrangement, the positive terminal and the negative terminal are connected to the copper sheet, which has good conductivity and is convenient for electrically connecting the test component to the photovoltaic component.

[0022] In some of the embodiments, the test body is provided with a through hole extending along the first direction, the tooling body is passed through the through hole, and the test body is located in the middle part of the tooling body.

[0023] Such an arrangement makes it easier for the test body to be installed on the tooling body.

[0024] In some of these embodiments, the material of the test body is aluminum.

[0025] Aluminum has low density, light weight, good conductivity, and high strength, which reduces the weight of the test body and increases the conductivity of the test body.

[0026] The embodiment of the present disclosure provides a testing system, including a testing device and the above-mentioned testing fixture, wherein the testing device is electrically connected to the testing fixture to test the electrical performance of a photovoltaic module.

[0027] The test system provided by the embodiment of the present disclosure is conducive to installing and fixing single-glass C-edge-free curved frame photovoltaic modules, and improves the working efficiency and installation accuracy of the test tooling, thereby improving the accuracy of the photovoltaic module test results.

Single-glass photovoltaic modules with curved frames without C-edges include laminates and single-glass curved frames without C-edges, and the curved frames include two support bars that are arranged back to back and extend back to the laminates. Due to the particularity of single-glass photovoltaic modules with curved frames without C-edges, it is easy to cause hidden cracks when using suction cups to install and fix such photovoltaic modules.

[0040] Based on this, reference Figure 1 The embodiment of the present disclosure provides a test tool 100 for installing and testing a single-glass C-edge-free curved frame photovoltaic module.

[0041] refer to Figure 2 and Figure 3 The test fixture 100 includes a fixture body 10, a test assembly 20 and two fixing members 30. The fixture body 10 includes a first end 11 and a second end 12 opposite to each other along a first direction. Exemplarily, the fixture body 10 extends in a left-right direction, with the left end being the first end 11 and the right end being the second end 12. The test assembly 20 is connected to the fixture body 10.

[0042] Each fixing member 30 includes a fixing portion 31, a bending portion 32 and a clamping portion 33 connected in sequence. Exemplarily, the fixing portion 31, the bending portion 32 and the clamping portion 33 are an integrated structure. The fixing portion 31, the bending portion 32 and the clamping portion 33 are connected in sequence along the up-down direction.

[0043] The fixing portion 31 extends along the first direction, and the two fixing portions 31 are respectively connected to the first end 11 and the second end 12. Exemplarily, the fixing portion 31 extends along the left-right direction.

[0044] The bending direction of the bending portion 32 is perpendicular to the first direction. Exemplarily, the bending portion 32 extends in the up-down direction. The upper end of the bending portion 32 is connected to the fixing portion 31 , and the lower end of the bending portion 32 is connected to the clamping portion 33 .

Exemplarily, the clamping portion 33 and the fixing portion 31 are both located on the left side of the bending portion 32. Or the clamping portion 33 and the fixing portion 31 are both located on the right side of the bending portion 32.

[0046] The fixing portion 31, the bending portion 32 and the clamping portion 33 form a clamping slot 34; the two clamping slots 34 are arranged opposite to each other along the first direction. For example, the clamping slot 34 at the left end opens to the right, and the clamping slot 34 at the right end opens to the left. The two clamping slots 34 are used to clamp two support bars 511 placed opposite to each other along the first direction.

[0047] In the test fixture 100 provided in the embodiment of the present disclosure, the fixing parts 31, the bending parts 32 and the clamping parts 33 of the two fixing members 30 respectively form two clamping grooves 34 that are opened and arranged opposite to each other. Since the two support bars 511 of the arc-shaped frame 51 without C-edge are placed opposite to each other along the first direction, the two clamping grooves 34 are respectively clamped with the two support bars 511, and the laminate does not need to contact the test fixture 100 and is stably fixed on the arc-shaped frame 51, thereby avoiding deformation of the laminate due to stress.

[0048] The test fixture 100 provided in the embodiment of the present disclosure is not prone to hidden crack problems when installing and fixing the single-glass photovoltaic component 5 with a curved frame 51 without a C-edge.

The first fixing member includes a first fixing portion, a first bend and a first clamping portion, the first fixing member forms a first clamping groove 34, and the first fixing portion of the first fixing member is connected to the first end 11. The second fixing member is located at the right end. The second fixing member includes a second fixing portion, a second bend portion 32 and a second clamping portion, the second fixing member forms a second clamping groove 34, and the second fixing portion of the second fixing member is connected to the second end 12. In other embodiments, the first fixing member can be connected to the second end 12, and the second fixing portion can be connected to the first end 11.

[0051] refer to Figure 1 and Figure 2 , exemplarily, a fixing groove is provided at the lower part of the first end 11, the first fixing part is located in the fixing groove, and a bolt is fixedly connected between the first end 11 and the first fixing part from top to bottom. , exemplarily, the first end 11 has 4 M3 fixing bolts.

[0052] refer to Figure 1 and Figure 2 , exemplarily, the shape and thickness of the first fixing portion are different from the shape and thickness of the second fixing portion. In other embodiments, the shape and thickness of the first fixing portion may be the same as the shape and thickness of the second fixing portion.

[0053] Exemplarily, the shape and thickness of the first bending portion are the same as the shape and thickness of the second bending portion. The shape and thickness of the first clamping portion are the same as the shape and thickness of the second clamping portion. The shape and thickness of the first card slot are the same as the shape and thickness of the second card slot.

[0054] In some embodiments, the materials of the two fixing members 30 are both polyoxymethylene resin.

[0055] Polyoxymethylene resin has high tensile strength and rigidity, can bear large loads, and is easy to fix and flip photovoltaic modules 5. It also has good friction resistance and wear resistance and is not easy to be damaged.

[0056] refer to Figures 1 to 3 In some embodiments, the test fixture 100 also includes a spring assembly 40, which includes a movable end 41, a spring 42 and a fixed end 43 connected in sequence along a first direction, the movable end 41 is connected to the second end 12, and the fixed end 43 is connected to the fixed portion 31 of one of the two fixing members 30.

[0057] With such arrangement, the spring assembly 40 can adjust the distance between the two fixing parts 30 , which is beneficial for using the test tool 100 on photovoltaic modules 5 of different sizes, and is convenient for installing and disassembling the photovoltaic modules 5 . The elastic action of the spring assembly 40 can avoid deformation of the frame of the photovoltaic module 5 .

[0058] Exemplarily, the movable end 41 of the spring assembly 40 is connected to the second end 12 , and the fixed end 43 of the spring assembly 40 is connected to the second fixed portion.

[0059] Exemplarily, there are two springs 42 arranged in parallel front and back. In other embodiments, the spring 42 can be one or more.

[0060] It is understandable that the spring 42 has a good stretching effect and a long service life, so that the spring 42 can control the force between the two fixing members 30 so as not to deform the frame of the photovoltaic module 5. The test fixture 100 cannot fall off due to insufficient tension of the spring 42 when the photovoltaic module 5 is turned over.

[0065] With such arrangement, when the spring 42 is extended and retracted along the first direction, the guide post 44 can follow the spring 42 to move in the movable track 411 , thereby ensuring the stretching effect of the spring 42 and enabling the spring 42 to be accurately reset.

[0066] Exemplarily, the left end of the guide post 44 is located on the movable track 411 , the spring 42 is sleeved on the middle portion of the guide post 44 , and the right end of the guide post 44 is fixed to the second fixing portion along the left-right direction.

[0067] Exemplarily, the number of springs 42 is equal to the number of guide pillars 44 .

[0068] Exemplarily, when the test fixture 100 is used, the spring 42 is stretched first, and the guide post 44 moves to the right end in the movable track 411, increasing the distance between the two fixings 30, and the photovoltaic component 5 is located between the two fixings 30, and the support bars 511 at both ends of the photovoltaic component 5 are respectively located in the two slots 34. The spring 42 is contracted, and the guide post 44 moves to the left end in the movable track 411, reducing the distance between the two fixings 30 until the photovoltaic component 5 is clamped. Then the photovoltaic component 5 is connected to the test fixture 100 for testing. After the test, the spring 42 is stretched to remove the photovoltaic component 5 from between the two fixings 30.

[0069] In some embodiments, the spring 42 is connected to the movable end 41 by welding, and the spring 42 is connected to the fixed end 43 by welding.

[0070] With such arrangement, the welding connection strength is high, which prevents the spring 42 from being separated from the movable end 41 and the fixed end 43 when expanding or contracting, thereby preventing the photovoltaic module 5 from being damaged.

[0071] Exemplarily, the portion where the movable end 41 and the spring 42 are connected is a steel sheet, and the spring 42 and the steel sheet of the movable end 41 are fixed by spot welding.

[0072] Exemplarily, the portion where the fixed end 43 is connected to the spring 42 is a steel sheet, and the spring 42 and the steel sheet of the fixed end 43 are fixed by spot welding.

[0073] refer to Figure 2 and Figure 3 In some embodiments, a fixing member 30 is connected to a guide column 44 by bolt connection.

[0074] Such an arrangement improves the connection stability between the fixing member 30 and the guide post 44 , making it difficult for the guide post 44 to separate from the fixing member 30 .
