[0002] Currently, solar energy, as a clean and renewable energy source, has received widespread attention for its development and utilization. Photovoltaic modules, as the core component of a solar power generation system, directly affect the power generation efficiency and stability of the entire system. Therefore, rigorous electrical performance testing during the production process of photovoltaic modules is a key step in ensuring product quality.

[0003] Electrical performance testing can accurately evaluate important parameters of photovoltaic modules, such as output power, short-circuit current, and open-circuit voltage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-5 This utility model discloses a testing fixture for photovoltaic module production, including a test platform 1. A placement seat 2 for placing a photovoltaic module 3 is fixedly connected to the center of the top surface of the test platform 1. A conductive seat 5 of the photovoltaic module 3 is detachably connected to a conductive component. A linkage mechanism that drives the conductive component to connect with the conductive seat 5 of the photovoltaic module 3 is detachably connected to the photovoltaic module 3.

[0031] The linkage mechanism includes a drive component located at the bottom of the test bench 1 and adjustment components symmetrically arranged on both sides of the placement seat 2. The drive component is used to drive the two adjustment components to move in opposite directions, and the adjustment components are used to clamp the photovoltaic module 3.

[0032] The conductive component is positioned between the two adjustment components and on one side of the top surface of the test bench 1.

[0033] This invention enables the driving component to clamp the photovoltaic module 3 while simultaneously driving the adjusting component to insert the conductive component into the conductive base 5 of the photovoltaic module 3. This not only improves the continuity of the photovoltaic module 3 test but also effectively enhances the test efficiency.

[0034] Further optimization of the scheme: the conductive component includes a first slide groove opened on the test platform 1, a first slider slidably connected in the first slide groove, a conductive plate 6 fixedly connected to one end of the first slider extending out of the top surface of the test platform 1, a conductive elastic top post 8 fixedly connected to the side of the conductive plate 6 facing the conductive seat 5 of the photovoltaic module 3, and the conductive elastic top post 8 connected to the external testing equipment through the wire 7.

[0035] The first slider moves the conductive plate 6, which in turn moves the conductive elastic top post 8 into the conductive base 5 of the photovoltaic module 3. Then, the photovoltaic module 3 is tested by an external testing device connected by the wire 7.

[0036] In a further optimized design, a rectangular plate 18 is fixedly connected to one end of the first slider extending from the bottom surface of the test platform 1. Multiple second springs 21 are fixedly connected to the end of the rectangular plate 18 facing the drive assembly. The end of the second spring 21 away from the rectangular plate 18 is fixedly connected to the bottom surface of the test platform 1 through a connecting plate.

[0037] When the driving component moves the rectangular plate 18 closer to the connecting plate, the rectangular plate 18 moves the conductive plate 6 synchronously through the first slider. When the rectangular plate 18 approaches the connecting plate, multiple second springs 21 are compressed. After the driving component separates from the rectangular plate 18, the elasticity of the multiple second springs 21 drives the rectangular plate 18 away from the connecting plate. At the same time, the rectangular plate 18 drives the conductive plate 6 away from the photovoltaic module 3 through the first slider. At this time, the conductive elastic top post 8 separates from the conductive base 5 of the photovoltaic module 3.

[0038] To facilitate the separation of the conductive elastic top post 8 from the conductive base 5 of the photovoltaic module 3, a rear baffle 4 is provided at the first slide groove. The rear baffle 4 is fixedly connected to the top surface of the test platform 1. A groove is provided at the bottom of the rear baffle 4. The groove is connected to the first slide groove and is adapted to the conductive plate 6, so that the conductive plate 6 can move effectively along the first slide groove through the groove.

[0039] By blocking the photovoltaic module 3 with the rear baffle 4, the conductive elastic top post 8 can be effectively separated from the conductive base 5 of the photovoltaic module 3.

[0040] Further optimization of the scheme: the drive component includes a U-shaped seat 9 fixedly connected to the bottom surface of the test bench 1. A bidirectional lead screw 10 is rotatably connected inside the U-shaped seat 9. The bidirectional lead screw 10 is threadedly connected to two threaded plates 12. The ends of the two threaded plates 12 away from the bidirectional lead screw 10 are respectively located on both sides of the rectangular plate 18. A second wedge plate 20 is fixedly connected to the opposite side of the two threaded plates 12. A first wedge plate 19 is detachably connected to the second wedge plate 20. The two first wedge plates 19 are respectively fixedly connected to both sides of the rectangular plate 18.

[0041] Either end of the bidirectional lead screw 10 passes through the U-shaped seat 9, and a motor 11 is connected to the end of the bidirectional lead screw 10 that passes through the U-shaped seat 9. The motor 11 is fixedly connected to the U-shaped seat 9.

[0042] The motor 11 drives the bidirectional lead screw 10 to rotate, and the bidirectional lead screw 10 drives the two threaded plates 12 to move closer or further apart. When the two threaded plates 12 move closer together, and the second wedge plate 20 abuts against the first wedge plate 19, the two threaded plates 12 continue to move closer together. The two second wedge plates 20 drive the rectangular plate 18 to move closer to the connecting plate through the two first wedge plates 19.

[0043] Further optimization of the scheme: the adjustment component includes a movable plate 13 that is slidably connected to the top surface of the test bench 1. A synchronization plate 14 is provided on the side of the movable plate 13 facing the placement seat 2. A clamping plate 16 is provided on the side of the synchronization plate 14 away from the movable plate 13. The clamping plate 16 is detachably connected to the photovoltaic module 3.

[0044] The moving plate 13 drives the synchronous plate 14 to move, and the synchronous plate 14 drives the clamping plate 16 to move. When the two clamping plates 16 come close to each other, they can clamp the photovoltaic module 3.

[0045] In a further optimized design, the movable plate 13 is fixedly connected to the threaded plate 12 via the second slider, and the second slider is slidably connected to the second groove, which is located on the test bench 1.

[0046] The threaded plate 12 drives the movable plate 13 to move through the second slider, so that the two movable plates 13 can move closer to each other or further apart.

[0047] In a further optimized design, a screw 15 is threadedly connected to the center of the moving plate 13, and the screw 15 abuts against the synchronization plate 14.

[0048] The distance between the moving plate 13 and the synchronization plate 14 can be adjusted by rotating screw 15.

[0049] In a further optimized design, guide posts are symmetrically arranged on one end of the clamping plate 16 facing the synchronization plate 14. One end of the guide post is fixedly connected to the clamping plate 16, and the other end of the guide post passes through the synchronization plate 14 and the moving plate 13 in sequence.

[0050] The clamping plate 16 can be effectively moved horizontally by two guide posts.

[0051] To further optimize the design, a first spring 17 is fitted onto the guide post located between the clamping plate 16 and the synchronization plate 14. The two ends of the first spring 17 are fixedly connected to the clamping plate 16 and the synchronization plate 14, respectively. By rotating the screw 15, the distance between the two clamping plates 16 can be adjusted according to the model of the photovoltaic module 3, thus adapting to different models of photovoltaic modules 3. Adjusting the distance between the two clamping plates 16 allows the conductive seat 5 on different models of photovoltaic modules 3 to correspond with the conductive elastic top post 8, enabling the conductive elastic top post 8 to be effectively inserted into the conductive seat 5 on the photovoltaic module 3.

[0052] The design was further optimized by fixing flexible anti-slip pads to the opposite sides of the two clamping plates 16. The flexible anti-slip pads enable the two clamping plates 16 to effectively clamp the photovoltaic module 3.

[0053] Working process: When testing photovoltaic module 3, first adjust the distance between the two clamping plates 16 according to the model of photovoltaic module 3 to ensure that when the flexible anti-slip pad contacts photovoltaic module 3, the inclined surfaces of the second wedge plate 20 and the first wedge plate 19 are completely overlapped. Tighten screw 15, which can drive the synchronous plate 14 and clamping plate 16 to move horizontally, thereby adjusting the distance between the two clamping plates 16.

[0054] Then, place the photovoltaic module 3 on the placement seat 2, with the conductive seat 5 on the photovoltaic module 3 facing the conductive plate 6. At the same time, the photovoltaic module 3 abuts against the rear baffle 4. Then, start the motor 11, which drives the bidirectional lead screw 10 to rotate forward. The bidirectional lead screw 10 rotates forward, which drives the two threaded plates 12 to move closer to each other. At the same time, the moving plate 13 and the clamping plate 16 move towards the photovoltaic module 3. When the flexible anti-slip pad moves and contacts the photovoltaic module 3, the inclined surfaces of the second wedge plate 20 and the first wedge plate 19 completely overlap. Then, the threaded plates 12 continue to move closer to each other. At this time, the clamping plate 16 compresses the first spring 17, and the second wedge plate 20 squeezes the first wedge plate 19 to move towards the photovoltaic module 3. The first wedge plate 19 can drive the conductive plate 6 and the conductive elastic top post 8 to move towards the photovoltaic module 3, so that the conductive elastic top post 8 can be inserted into the conductive seat 5 on the photovoltaic module 3. Finally, start the external testing equipment to perform electrical testing on the photovoltaic module 3.

[0055] After the test is completed, the motor 11 drives the bidirectional lead screw 10 to reverse, causing the two threaded plates 12 to move away from each other. When the second wedge plate 20 no longer presses against the first wedge plate 19 and moves away from the first wedge plate 19, the elasticity of multiple second springs 21 drives the rectangular plate 18 away from the connecting plate. At the same time, the rectangular plate 18 drives the conductive plate 6 away from the photovoltaic module 3 through the first slider. At this time, the photovoltaic module 3 is blocked by the rear baffle 4, preventing the photovoltaic module 3 from moving towards the conductive plate 6, thus enabling the conductive elastic top post 8 to separate from the conductive seat 5 of the photovoltaic module 3.

[0056] The photovoltaic module 3 can be tested by repeating the above process.
