[0002] As the production process of solar photovoltaic panels matures, the single-line capacity continues to increase, and the mechanization and automation process is accelerating. However, the electroluminescent test (EL test) link is the shortcoming of the front-end production line of photovoltaic panels. The EL test is operated in a double-string parallel feeding mode. The distance between two strings of batteries entering the equipment at a time, a conventional component needs to be fed three times before the test can be completed. The rhythm is much slower than the speed of the assembly line and the welding machine. In order to avoid the above problems, the conventional production line EL test basically adopts a parallel distribution method to increase the test machine to speed up the overall production line rhythm, which not only increases the cost of the production line preparation, but also increases the subsequent operation and maintenance and labor costs.
[0003] In view of this, it is necessary to design a new photovoltaic module panel testing device that can effectively solve or alleviate the above technical problems. Utility Model Content

[0030] First of all, it should be noted that the transmission direction mentioned in the present application is the moving direction of the photovoltaic component panel 4.
[0031] like Figure 1 and Figure 2 As shown, the basic embodiment of the present application provides a photovoltaic module panel electroluminescence testing device, comprising:
[0032] A conveying member 1, which is arranged in plurality and spaced apart along the transmission direction of the photovoltaic component panel 4; a plurality of test members 2, which are used for performing an electroluminescent test on the photovoltaic component panel 4; and a fixing member 3, which is used for fixing the photovoltaic component panel 4 on one side of the plurality of test members 2.
[0033] In order to facilitate understanding of the technical solution of the photovoltaic module panel electroluminescence testing device of the present application, the technical effects of the photovoltaic module panel electroluminescence testing device of the present application will be specifically described below with reference to the accompanying drawings.
[0034] like Figure 1 As shown, the photovoltaic module panel electroluminescence testing device of the present application includes a conveying member 1, and the conveying members 1 are arranged in plurality and are spaced apart along the transmission direction of the photovoltaic module panel 4. For example, the number of conveying members 1 can be three, which are arranged at the upper and lower ends of the photovoltaic module panel 4 and the middle of the photovoltaic module panel along the transmission direction of the photovoltaic module panel 4 respectively. A plurality of test members 2 are arranged to perform electroluminescence testing on the photovoltaic module panel 4. A fixing member 3 is arranged to fix the photovoltaic module panel 4 on one side of the plurality of test members 2. The photovoltaic module panel 4 can be moved on the conveying member 1. After moving to a fixed position, the fixing member 3 fixes the photovoltaic module panel 4. The test member 2 performs electroluminescence testing on the photovoltaic module panel 4. By arranging a plurality of conveying members 1, the photovoltaic module panel 4 only needs to be fed once to complete the test, thereby improving the electroluminescence testing efficiency of the photovoltaic module panel 4 and reducing the cost of the production line. At the same time, the fixing member 3 fixes the photovoltaic module panel 4, thereby improving the stability of the photovoltaic module panel 4 and improving the accuracy of the test.
[0035] In some embodiments, part or all of the conveying member 1 is provided with a rotating structure on the side facing away from the photovoltaic component panel 4, and the rotating structure can adjust the conveying member 1 to a position that does not block the test piece 2 when the fixing member 3 fixes the photovoltaic component panel 4, wherein the conveying members 1 arranged at both ends of the photovoltaic component panel 4 are provided with a rotating structure on the side facing away from the photovoltaic component panel 4, and when the fixing member 3 fixes the photovoltaic component panel 4, the conveying members 1 arranged at both ends of the photovoltaic component panel 4 are adjusted to a position that does not block the test piece 2, which can prevent the conveying member 1 from blocking part of the photovoltaic component panel 4 and hindering the testing of the test piece 2, thereby reducing the number of tests and improving the electroluminescent testing efficiency of the photovoltaic component panel 4.
[0036] In some embodiments, part or all of the conveying member 1 is provided with a lifting structure on the side facing away from the photovoltaic component panel 4. The lifting structure can adjust the conveying member 1 to a position that does not block the test piece 2 when the fixing member 3 fixes the photovoltaic component panel 4. The conveying member 1 arranged between the two ends of the photovoltaic component panel 4 can be provided with a lifting structure. When the fixing member 3 fixes the photovoltaic component panel 4, the conveying member 1 between the two ends of the photovoltaic component panel 4 is adjusted to a position that does not block the test piece 2. This can prevent the conveying member 1 from blocking part of the photovoltaic component panel 4 and hindering the testing of the test piece 2, thereby reducing the number of tests and improving the electroluminescent testing efficiency of the photovoltaic component panel 4.
[0037] In some embodiments, the fixing member 3 is a retractable fixing member. When the photovoltaic module panel 4 moves on the conveyor 1, the fixing member 3 shrinks to one side of the photovoltaic module panel 4. The fixing member 3 can be below the photovoltaic module panel 4. When the photovoltaic module panel 4 moves to a specified position, the fixing member 3 extends to the photovoltaic module panel 4 to fix the photovoltaic module panel 4. When testing the photovoltaic module panel 4, the shaking of the photovoltaic module panel 4 is reduced, thereby improving the accuracy of electroluminescence detection.
[0038] like Figure 2 As shown, in some embodiments, the retractable fixing member includes a telescopic rod 32, a fixed support 31 connected to the telescopic rod 32, and a driving member 33 for driving the telescopic rod 32 to retract and retract. When the photovoltaic component panel 4 moves on the conveying member 1, the driving member 33 drives the telescopic rod 32 to retract to one side of the photovoltaic component panel 4, which may be below the photovoltaic component panel 4. When the photovoltaic component panel 4 moves to a specified position, the driving member 33 drives the telescopic rod 32 to extend, and the photovoltaic component panel 4 is fixed by the fixed support 31. When testing the photovoltaic component panel 4, the shaking of the photovoltaic component panel 4 is reduced, thereby improving the accuracy of electroluminescent detection.
[0039] like Figure 1 and Figure 2As shown, in some embodiments, the fixing support 31 is a supporting block capable of clamping the edge of the photovoltaic component panel 4. By clamping the edge of the photovoltaic component panel 4 by the supporting block, the photovoltaic component panel 4 can be fixed on the one hand, and on the other hand, clamping the edge of the photovoltaic component panel 4 can prevent the supporting block from blocking the photovoltaic component panel 4 and affecting the test of the test piece 2, thereby improving the accuracy of electroluminescent detection.
[0040] In some embodiments, a plurality of retractable fixing members are provided to be able to clamp each side edge of the photovoltaic component panel 4. On the one hand, the photovoltaic component panel 4 can be fixed; on the other hand, clamping the edge of the photovoltaic component panel 4 can prevent the supporting block from blocking the photovoltaic component panel 4 and affecting the test of the test piece 2, thereby improving the accuracy of electroluminescent detection.
[0041] In some embodiments, the test piece 2 is arranged between adjacent conveying members 1. Multiple test pieces 2 can be arranged and evenly distributed between adjacent conveying members 1. On the one hand, multiple test pieces 2 can reduce the number of tests and improve the electroluminescence test efficiency of the photovoltaic module panel 4. On the other hand, the test pieces 2 are evenly distributed between adjacent conveying members 1, so that every place of the test piece 2 can be tested, thereby improving the accuracy of electroluminescence detection.
[0042] In some embodiments, the test piece 2 includes a camera facing the photovoltaic component panel 4 and a tester connected to the camera signal. By arranging multiple test pieces 2 on one side of the photovoltaic component panel 4, the number of tests can be reduced and the electroluminescence test efficiency of the photovoltaic component panel 4 can be improved.

For example, the conveying member 1 can be arranged below the photovoltaic module panel 4, and there can be three conveying members 1, one along the photovoltaic module panel 4 and the other along the photovoltaic module panel 4. The transmission direction of the panel 4 is set at both ends and the middle of the photovoltaic component 4.

The lifting structure can adjust the conveying member 1 to a position that does not block the test piece 2 when the fixing member 3 fixes the photovoltaic component panel 4. The fixing member 3 is used to fix the photovoltaic component panel 4 on one side of multiple groups of the test pieces 2. For example, the fixing member 3 can be set below the photovoltaic component panel 4. The fixing member 3 can be a retractable fixing member, and the retractable fixing member includes a telescopic rod 32 and a telescopic rod 3. 2 and a driving member 33 for driving the telescopic rod 32 to extend and retract, the fixed support 32 can clamp the edge of the photovoltaic component panel 4, and a plurality of retractable fixing members can be provided to clamp the edge of each side of the photovoltaic component panel 4.

The staff places the photovoltaic module panel 4 on the conveyor 1, and the conveyor 1 moves the photovoltaic module panel 4 to the specified position. The driving member 33 drives the telescopic rod 32 to extend, so that the fixed support 31 on the telescopic rod 32 fixes the photovoltaic module panel 4, and the conveyor 1 at both ends of the photovoltaic module panel 4 rotates to a position that does not block the test of the test piece 2. The conveyor 1 in the middle of the two ends of the photovoltaic module panel 4 is lowered to a position that does not block the test of the test piece 2. The test piece 2 performs an electroluminescence test on the photovoltaic module panel 4, which improves the test efficiency of the photovoltaic module panel 4 and reduces the cost of the production line.
[0046] It can be seen from the above description that the advantages of the present application are that, first, the present application sets a plurality of conveying members 1 under the photovoltaic component panel 4, and the plurality of conveying members 1 can complete the test only by feeding the photovoltaic component panel 4 once, thereby improving the electroluminescent test efficiency of the photovoltaic component panel 4 and reducing the cost of the production line; second, part or all of the conveying members 1 are provided with a rotating structure or a lifting structure, and the conveying member 1 can be adjusted to a position that does not block the test member 2 when performing the electroluminescent test, thereby avoiding multiple measurements and improving the test efficiency; third, a fixing member 3 is provided on one side of the photovoltaic component panel 4, and the photovoltaic component panel 4 is fixed by the fixing member 3, thereby improving the stability of the photovoltaic component panel 4 during the test and improving the accuracy of the test.
