Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic module technology, specifically to a flexible photovoltaic module testing auxiliary device. Background Technology

[0002] Flexible photovoltaic (PV) modules are a new type of solar cell module characterized by their flexibility and thinness. Compared to traditional silicon-based solar cell modules, flexible PV modules have a wider range of applications and higher energy efficiency. Testing flexible PV modules can reveal problems that arise during actual use, thereby ensuring quality control in product design and overall quality management.

[0003] According to a Chinese patent publication (CN216490399U), a flexible photovoltaic module testing auxiliary device includes a housing for supporting the flexible photovoltaic module under test; a support mechanism fixed to the housing; and a vacuum suction cup mechanism connected and fixed to the support mechanism. This device can control the flatness of the flexible photovoltaic module under test on a horizontal test plane, enabling the testing of electrical performance parameters and IV curves in a fully unfolded state. This solves the problem of the bending characteristics of flexible photovoltaic modules affecting the accuracy of test results, thus improving the accuracy of the test results.

[0004] The device controls the flatness of the flexible photovoltaic module under test on the horizontal test plane. However, existing devices still have the following problems: due to the characteristics of flexible photovoltaic modules, which are curlable and flexible, and because their substrates are different from those of photovoltaic modules with ordinary rigid substrates, their performance needs to be tested under a certain degree of curl. Therefore, an auxiliary device for testing flexible photovoltaic modules is proposed. Utility Model Content

[0008] And a connecting frame located above the base plate, a flexible photovoltaic module located above the connecting frame, and a lifting component fixedly connected to the bottom surface of the connecting frame;

[0009] An adjustment component is fixedly connected to the right side of the connecting frame.

[0010] Preferably, the adjustment component includes a motor fixedly connected to the right side of the connecting frame. The left end of the motor output rod extends through the right side of the connecting frame into the interior of the connecting frame. A first double-ended threaded rod is fixedly connected to the left end of the motor output rod. Two sliding plates are arranged symmetrically inside the connecting frame. The left end of the first double-ended threaded rod extends threadedly through the right side of the two sliding plates into the left side of the two sliding plates. The left end of the first double-ended threaded rod is rotatably connected to the left side of the interior of the connecting frame through a bearing seat. The rear side of the sliding plate is slidably connected to the rear side of the interior of the connecting frame. C-shaped frames are fixedly connected to the top surfaces of both sliding plates. The two C-shaped frames are arranged symmetrically. The flexible photovoltaic module is located between the two C-shaped frames. By bringing the two sliding plates closer to each other, the curvature of the flexible photovoltaic module is changed, thereby enabling the detection of the flexible photovoltaic module under different curvatures.

[0011] Preferably, a support frame is fixedly connected to the front and rear sides of the C-shaped frame. A second double-threaded rod and two sliders are provided on the inner side of the support frame.

Two push rods are hinged to the top surface of the clamping plate. The top surfaces of the two push rods are respectively hinged to the bottom surfaces of the two sliders. The clamping plate is located above the flexible photovoltaic module.

This prevents the flexible photovoltaic modules from moving during the testing process and affecting the testing accuracy. At the same time, a sliding plate moves the two C-shaped frames closer or further apart, thereby adjusting the curvature of the flexible photovoltaic module and simulating the application of the flexible module under various curling conditions, making the testing conditions more accurate.

[0019] This flexible photovoltaic module testing auxiliary device uses a lifting component and an electric push rod to raise and lower the height of the connecting frame, thereby raising and lowering the flexible photovoltaic module. This enables the testing of the flexible photovoltaic module at different heights and improves the convenience of the device in assisting the testing of flexible photovoltaic modules.

By adjusting the component 41, the push rod 419 drives the clamping plate 4110 to rise and fall, thereby clamping and fixing the flexible photovoltaic module 5 of different thicknesses in the C-shaped frame 415. This prevents the flexible photovoltaic module 5 from moving during the testing process and affecting the testing accuracy. At the same time, the sliding plate 413 drives the two C-shaped frames 415 to move closer or further apart, thereby adjusting the curvature of the flexible photovoltaic module 5 and simulating the application of the flexible module 5 under various curling conditions, making the testing conditions more accurately simulated.

[0032] A support frame 416 is fixedly connected to the front and rear sides of the C-shaped frame 415.

[0036] Example 2: Based on Example 1, a preferred embodiment of the flexible photovoltaic module testing auxiliary device provided by this utility model is as follows: Figure 1 and Figure 2 As shown: The lifting assembly 40 includes a connecting frame 402 fixedly connected to the bottom surface of the connecting frame 3. An electric push rod 401 is provided below the connecting frame 402. The bottom surface of the electric push rod 401 is fixedly connected to the top surface of the base plate 1, and the top surface of the output rod of the electric push rod 401 is fixedly connected to the bottom surface of the connecting frame 402. Through the lifting assembly 40, the height of the connecting frame 3 is raised and lowered by the electric push rod 401, thereby raising and lowering the flexible photovoltaic module 5. This realizes the detection of the flexible photovoltaic module 5 at different heights and improves the convenience of the device for assisting in the detection of flexible photovoltaic modules.

[0037] Two first slide rods 403 are fixedly connected to the bottom surface of the connecting frame 402. The two first slide rods 403 are symmetrically arranged. Two slide cylinders 404 are fixedly connected to the top surface of the base plate 1. The bottom end of the first slide rod 403 slides through the top surface of the slide cylinder 404 and extends into the interior of the slide cylinder 404.

[0038] In use, the flexible photovoltaic module 5 is placed in the C-frame 415. The rotating plate 4112 is rotated, and the second double-headed threaded rod 417 rotates, causing the two sliders 418 to move closer to each other and drive the push rod 419 to move. The push rod 419 pushes the clamping plate 4110 to move downward, so that the clamping plate 4110 drives the rubber plate 4111 downward to clamp and fix the flexible photovoltaic module 5 in the C-frame 415. The insertion rod 4113 is inserted into the through hole and slot, thereby limiting the rotation plate 4112. When it is necessary to detect the flexible photovoltaic module 5 at different curvatures, the motor 411 is turned on. The first double-headed threaded rod 412 drives the two sliding plates 413 to move closer to each other or further apart. The sliding plates 413 slide on the second sliding rod 411 and drive the two C-frames 415 to move, thereby changing the curvature of the flexible photovoltaic module 5.

[0039] When it is necessary to move the flexible photovoltaic module 5 to different heights for testing, the electric push rod 401 is activated. The output rod of the electric push rod 401 drives the connecting frame 402 to move upward, which causes the connecting frame 3 to move upward and drives the flexible photovoltaic module 5 to move upward. When the connecting frame 402 moves, it drives the first slide rod 403 to slide in the slide cylinder 404.
