As photovoltaic technology develops in the direction of diversification and refinement, the installation scenarios of photovoltaic cells have become increasingly complex and diverse, expanding from conventional flat roofs to curved carport roofs, wavy building exterior walls and other curved structures. These scenarios place strict demands on the bending adaptability of photovoltaic cells. If the bending strength is insufficient, photovoltaic cells are prone to cracks, breakage, or even failure during long-term use, which will not only greatly reduce the power generation efficiency, but may also cause safety hazards and increase maintenance costs and the difficulty of overall system operation and maintenance. Therefore, a strength detection device is required to test the bending strength of photovoltaic cells during production.

A protective pad 24 is fixedly installed on the inner wall of the mounting frame 23. A plurality of eccentric rollers 25 are rotatably installed on the upper end of the mounting frame 23, and a plurality of conveying rollers 26 are rotatably installed on the lower end of the mounting frame 23. The photovoltaic panel 5 to be detected is fixed between the eccentric rollers 25 and the conveying rollers 26. The limit assembly 22 is arranged on one side of the mounting frame 23, and is used to drive the plurality of eccentric rollers 25 and the conveying rollers 26 to rotate. A moving assembly 21 is arranged on the platform 101, and the limit assembly 22 is connected to one end of the moving assembly 21; The displacement mechanism 4 is arranged at the lower part of the box body 1 , and a pressure mechanism 3 is installed on the displacement mechanism 4 . The pressure mechanism 3 includes a hydraulic cylinder 32 , and a pressure roller 36 is arranged at the output end of the hydraulic cylinder 32 . The pressure roller 36 abuts against the lower surface of the photovoltaic panel 5 .

[0025] Specifically, the box 1 and the platform 101 serve as the basic support mechanism of the entire detection device, providing a foundation for the installation and fixation of the detection device. During the detection process, the control mechanism 2 adjusts and limits the position of the photovoltaic panel 5 to ensure the stability of the photovoltaic panel 5 during the detection process, and realizes the stable transportation of the photovoltaic panel 5 after the detection is completed.

[0026] The pressure-applying mechanism 3 serves as a power source and can provide controllable pressure. By applying different pressures to the lower surface of the photovoltaic panel 5 and observing the cracks that appear on the photovoltaic panel 5 under pressure, the corresponding bending strength is obtained. The pressure-applying mechanism 3 is moved by the displacement mechanism 4 to change the pressure-applying position, and the bending strength at different positions is obtained, thereby obtaining a more comprehensive strength test result.

[0027] The moving assembly 21 includes a fixed base 211, a first gear 213 is rotatably mounted on the upper end of the fixed base 211, a first motor 212 is fixedly mounted on one side of the fixed base 211, an output end of the first motor 212 is fixedly connected to the first gear 213, a first rack 214 is meshedly connected to the lower part of the first gear 213, the first rack 214 is slidably connected in the guide rail 215, and the guide rail 215 is fixedly mounted on the platform 101.

[0028] The moving component 21 is installed on the platform 101. By connecting with the limiting component 22, the movement of the limiting component 22 can be controlled, thereby adjusting and fixing the position of the photovoltaic panel 5. It can also cooperate with the limiting component 22 on the other side to detect the bending strength of the photovoltaic panel 5 when the middle part is bent after being squeezed from both sides, thereby further improving the comprehensiveness of the bending strength detection of the photovoltaic panel 5.

[0029] Specifically, the first motor 212 is started to drive the first gear 213 to rotate, and the first gear 213 drives the first rack 214 to slide along the guide rail 215. The guide rail 215 plays a role of precise guidance, ensuring that the first rack 214 can only move smoothly along the predetermined direction. The first rack 214 drives the limit assembly 22 and the mounting frame 23 to move synchronously, thereby realizing the position adjustment and fixation of the photovoltaic panel 5. After fixation, it continues to move, which can realize the extrusion of the photovoltaic panel 5 and obtain the bending strength under the condition of extrusion on both sides.

Compared with some simple driving structures, it can accurately adjust the position of the photovoltaic panel 5 according to a preset program, providing accurate initial conditions for subsequent bending strength testing.

[0031] The limiting assembly 22 includes a connecting frame 221 and a second motor 222. The connecting frame 221 is fixedly mounted on one end of the first rack 214. The second motor 222 is fixedly mounted on the upper end of the connecting frame 221. The output end of the second motor 222 is fixedly connected to a rotating shaft 223. The rotating shaft 223 is rotatably mounted on the connecting frame 221. A second gear 224 is fixedly sleeved on the rotating shaft 223. A third rack 226 is meshedly connected to one side of the second gear 224. The third rack 226 is fixedly mounted on the second rack 225. A limiting rod 231 is fixedly connected to one side of the mounting frame 23. The second rack 225 is slidably connected to the limiting rod 231. Two ends of the second rack 225 are respectively provided with A first meshing portion 2251 and a second meshing portion 2252 are provided, and an upper driven gear 227 and a lower driven gear 2210 are respectively provided on the upper and lower sides of the second rack 225, and the upper driven gear 227 and the lower driven gear 2210 are respectively fixedly sleeved on the eccentric roller 25 and the conveying roller 26, and the upper driven gear 227 and the lower driven gear 2210 are respectively meshed and connected with the first meshing portion 2251 and the second meshing portion 2252, and one end of the eccentric roller 25 and the conveying roller 26 are respectively fixedly sleeved with a first sprocket 228 and a second sprocket 2211, and the first sprocket 228 and the second sprocket 2211 are respectively sleeved with a first chain 229 and a second chain 2212.

[0032] The limiting components 22 are arranged on both sides of the upper end of the box body 1 and one side of the mounting frame 23, and are used to drive the eccentric roller 25 and the conveying roller 26 to rotate, thereby realizing the position limitation and conveyance of the photovoltaic panel 5 to be inspected.

[0033] In the initial state, the first meshing portion 2251 is meshed with the upper driven gear 227, and the second meshing portion 2252 is not meshed with the lower driven gear 2210. After the photovoltaic panel 5 is placed between the eccentric roller 25 and the conveying roller 26 on one side, the eccentric roller 25 and the conveying roller 26 on the other side are driven to move by the moving component 21 until both sides of the photovoltaic panel 5 are located between the eccentric roller 25 and the conveying roller 26, and the two ends of the photovoltaic panel 5 are respectively against the protective pad 24 to achieve the initial fixation of the photovoltaic panel 5. Subsequently, the second motor 222 is started to drive the rotating shaft 223 and the second gear 224 to rotate, and the second gear 224 drives the third rack 226 to move accordingly. The third rack 226 is fixedly mounted on the second rack 225, so the second rack 225 moves synchronously, causing the second meshing portion 2252 to gradually approach the lower driven gear 2210. During this process, the upper driven gear 227 drives the eccentric roller 25 and the first sprocket 228 connected thereto to rotate. The first sprocket 228 is meshed with the first chain 229 to cause the other eccentric rollers 25 to rotate synchronously. The portion of the eccentric roller 25 away from the central axis approaches the upper surface of the photovoltaic panel 5 until the photovoltaic panel 5 is pressed tightly. When clamped, the second motor 222 is automatically turned off to further fix the photovoltaic panel 5 and improve the stability during the pressure application process.

[0034] After the detection is completed, the second motor 222 is started again to drive the second rack 225 to continue moving. According to the above working principle, the eccentric roller 25 continues to rotate for a short distance and no longer presses the photovoltaic panel 5, and the upper driven gear 227 no longer meshes with the first meshing portion 2251. The lower driven gear 2210 begins to mesh with the second meshing portion 2252, and the lower driven gear 2210 and the conveying roller 26 are driven to rotate through the second meshing portion 2252 of the second rack 225, thereby conveying the photovoltaic panel 5 out, realizing automatic unloading, avoiding secondary damage to the photovoltaic panel 5 caused by manual unloading or damage to the staff by the damaged photovoltaic panel 5, and improving the safety of unloading.

[0035] Through the above technical solution, the photovoltaic panel 5 can be fixed and subsequently transported only by the movement of the second rack 225, thereby improving the functionality of the structure, reducing the use of power equipment, and lowering costs.

[0036] The hydraulic cylinder 32 is fixedly installed in the installation cabinet 31, and support plates 33 are fixedly connected on both sides of the upper end of the installation cabinet 31. A guide rod 34 is penetrated on the support plate 33, and the upper end of the guide rod 34 is fixedly connected to the base frame 35. The output end of the hydraulic cylinder 32 penetrates the installation cabinet 31 and is fixedly connected to the middle part of the lower surface of the base frame 35, and the pressure roller 36 is rotatably installed in the base frame 35.

[0037] The hydraulic cylinder 32 serves as the power source of the pressure mechanism 3 and can provide controllable pressure. It drives the pressure roller 36 through its output end to apply pressure to the lower surface of the photovoltaic panel 5. The pressure roller 36 abuts against the lower surface of the photovoltaic panel 5, and converts the pressure output by the hydraulic cylinder 32 into a bending force on the photovoltaic panel 5, thereby realizing the detection of the bending strength of the photovoltaic panel 5.

[0038] The displacement mechanism 4 includes a third motor 43 and a slide rail 44. The slide rail 44 is fixedly installed on the bottom inner wall of the box body 1. The third motor 43 is fixedly installed on one side of the box body 1. The output end of the third motor 43 is fixedly connected to a screw rod 42. The end of the screw rod 42 away from the third motor 43 is rotatably installed on the inner wall of the box body 1. A movable seat 41 is threadedly sleeved on the screw rod 42. The movable seat 41 is slidably connected to the slide rail 44. The movable seat 41 is fixedly connected to the bottom of the installation cabinet 31.

[0039] The displacement mechanism 4 is disposed at the lower part of the box body 1 and is used to adjust the position of the pressure mechanism 3 so that the pressure roller 36 can accurately abut against different positions of the lower surface of the photovoltaic panel 5 to achieve bending strength detection at different positions.

[0040] In summary, the working principle of a photovoltaic cell bending strength detection device according to an embodiment of the present invention is as follows: After placing the photovoltaic cell panel 5 between the eccentric roller 25 and the conveying roller 26 on one side, the first gear 213 is driven to rotate by starting the first motor 212, and the first gear 213 drives the first rack 214 to slide along the guide rail 215, and the first rack 214 drives the limit assembly 22 and the mounting frame 23 to move synchronously, so that the eccentric roller 25 and the conveying roller 26 on the other side move until both sides of the photovoltaic cell panel 5 are located between the eccentric roller 25 and the conveying roller 26, and the two ends of the photovoltaic cell panel 5 are respectively against the protective pad 24, so that the photovoltaic cell panel 5 is initially fixed, and then the second motor 222 is started to drive the rotating shaft 22 3 and the second gear 224 rotate, the second gear 224 drives the third rack 226 to move correspondingly, the third rack 226 is fixedly mounted on the second rack 225, so the second rack 225 moves synchronously, so that the second meshing portion 2252 gradually approaches the lower driven gear 2210, during this process, the upper driven gear 227 drives the eccentric roller 25 and the first sprocket 228 connected thereto to rotate, the first sprocket 228 is meshed with the first chain 229, so that the other eccentric rollers 25 rotate synchronously, and the part of the eccentric roller 25 away from the central axis approaches the upper surface of the photovoltaic panel 5 until the photovoltaic panel 5 is pressed tightly and clamped. At this time, the second motor 222 is automatically closed to further fix the photovoltaic cell panel 5 and improve the stability during the pressure application process. The third motor 43 is started to drive the screw rod 42 to rotate, and the screw rod 42 drives the movable seat 41 to move, so that the pressure mechanism 3 moves synchronously, and the pressure roller 36 is moved to the detection position and stopped. The hydraulic cylinder 32 is started to drive the pressure roller 36 to move upward to apply pressure to the photovoltaic cell panel 5, so that the photovoltaic cell panel 5 is bent. When cracks occur, the pressure strength and position at this time are recorded. The bending strength of different positions of the photovoltaic cell panel 5 is obtained according to multiple sets of tests. After the test is completed, the second motor 222 is started again. , driving the second rack 225 to continue to move. According to the above working principle, the eccentric roller 25 continues to rotate for a short distance and no longer presses the photovoltaic panel 5, and the upper driven gear 227 no longer meshes with the first meshing portion 2251, and the lower driven gear 2210 begins to mesh with the second meshing portion 2252. The lower driven gear 2210 and the conveying roller 26 are driven to rotate through the second meshing portion 2252 of the second rack 225, thereby conveying the photovoltaic panel 5 out, realizing automatic unloading, avoiding secondary damage to the photovoltaic panel 5 caused by manual unloading or damage to the staff by the damaged photovoltaic panel 5, and improving the safety of unloading.
