Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module testing and fixing technology, and in particular to a photovoltaic module testing and fixing frame. Background Technology

[0002] Currently, in the testing of photovoltaic (PV) modules, they are typically clamped onto a mounting frame for various performance tests. However, existing mounting frame clamping mechanisms have several problems. Traditional clamping mechanisms are often simple in structure, with insufficient locking, making it difficult to securely fix the PV modules. During testing, the PV modules are prone to shaking or displacement, leading to inaccurate test results. Moreover, existing clamping methods are inefficient, requiring significant time for adjustment and fixation, which not only increases testing costs but also reduces testing efficiency, failing to meet the needs of large-scale production and testing. Therefore, we propose a PV module testing mounting frame to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a photovoltaic module testing and fixing frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A photovoltaic module testing and fixing frame includes a base plate, a fixing platform fixed at the upper center of the base plate, an opening on the fixing platform, a reciprocating moving mechanism between opposite sidewalls within the opening, an extension structure rotatably connected to one end of the reciprocating moving mechanism, a support plate connected to one end of the extension structure, a lower end of the support plate slidably connected to the upper end of the base plate, a clamping mechanism fixed to the upper end of the support plate, and a T-shaped support plate fixed to the upper end of the fixing platform.

[0006] Preferably, the reciprocating moving mechanism includes forward and reverse screws rotatably connected between opposite sidewalls inside the opening, a servo motor is fixed on one side of the fixed platform, the output shaft of the servo motor is connected to one end of the forward and reverse screws, and movable blocks are threaded to both ends of the forward and reverse screws, with the movable blocks engaging inside the opening.

[0007] Preferably, the extended structure includes mounting blocks fixed at both ends of a movable block on the same side, one end of the two mounting blocks on the same side being rotatably connected to a folding frame, a guide rail fixed on one side of the bearing plate, movable blocks being engaged on both sides of the guide rail, and one end of the folding frame being rotatably connected between the two movable blocks.

[0008] Preferably, sliders are fixed on both sides of the lower end of the bearing plate, and four grooves are provided on the upper end of the base plate, with one slider on the same side engaging in one groove on the same side.

[0009] Preferably, the clamping mechanism includes a support plate fixed to the upper end of the support plate, a clamping plate fixed to the upper end of the support plate, and a plurality of pressure sensors evenly spaced on one side of the clamping plate.

[0010] Preferably, a rubber pad is installed at the upper end of the T-shaped support plate.

[0011] In this invention, when testing photovoltaic modules:

[0012] 1. Preparation: Install the base plate at the lower end of the testing mechanism to ensure the stability of the entire mounting frame. Carefully place the photovoltaic module to be tested on the upper end of the T-shaped support plate. The rubber pad installed on the T-shaped support plate can buffer and protect the photovoltaic module, preventing its surface from being scratched.

[0013] 2. Start the reciprocating movement mechanism: Turn on the servo motor. The output shaft of the servo motor drives the forward and reverse screws to rotate. Since the threads at both ends of the forward and reverse screws are in opposite directions, when the forward and reverse screws rotate, the movable blocks at both ends will move in opposite directions in a straight line within the opening. The movable blocks are engaged within the opening, ensuring the stability of its movement.

[0014] 3. Extended structure movement: As the movable block moves, the mounting blocks fixed at both ends of the movable block also move. The mounting blocks drive the folding frame to move. One end of the folding frame is rotatably connected between the movable blocks, and the movable blocks are engaged on the guide rail. Therefore, the movement of the folding frame pushes the movable blocks to slide on the guide rail, thereby driving the bearing plate to move. The slider at the lower end of the bearing plate slides in the groove on the base plate, ensuring the stability of the bearing plate movement.

[0015] 4. Clamping the photovoltaic module: The movement of the support plate causes the clamping mechanism fixed on it to move closer to the photovoltaic module. The clamping plate in the clamping mechanism gradually contacts both sides of the photovoltaic module. The pressure sensor can monitor the magnitude of the clamping force in real time. When the pressure reaches a suitable value, it indicates that the photovoltaic module has been firmly clamped. At this time, subsequent testing can be carried out, and the servo motor stops operating.

[0016] This utility model has the following advantages:

[0017] 1. Through the coordinated work of the reciprocating moving mechanism and the extension structure, the clamping mechanism can firmly clamp the photovoltaic module on both sides. Compared with the traditional clamping mechanism, it can more fully fix the photovoltaic module and prevent it from shaking or shifting during the testing process, thereby ensuring the accuracy of the test results.

[0018] 2. The automation and efficiency of the clamping process reduce the time spent on manual adjustment and fixing, greatly improving testing efficiency and meeting the needs of large-scale production and testing;

[0019] 3. It can adapt to photovoltaic modules of different sizes and shapes. By adjusting the parameters of the reciprocating moving mechanism and the extension structure, it can effectively clamp photovoltaic modules of different specifications, thus improving the versatility of the fixing frame.

[0020] In summary, this utility model can achieve a firm clamping mechanism on both sides of the photovoltaic module. Compared with traditional clamping mechanisms, it can more fully fix the photovoltaic module and prevent it from shaking or shifting during the testing process, thereby ensuring the accuracy of the test results. It can also effectively clamp photovoltaic modules of different specifications, improve the versatility of the fixing frame, greatly improve the testing efficiency, and meet the needs of large-scale production and testing.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4A photovoltaic module testing and fixing frame includes a base plate 7, a fixing platform 3 fixed at the upper middle part of the base plate 7, an opening 15 on the fixing platform 3, a reciprocating moving mechanism between opposite side walls within the opening 15, an extension structure rotatably connected to one end of the reciprocating moving mechanism, a bearing plate 12 connected to one end of the extension structure, a clamping mechanism fixed to the upper end of the base plate 7, and a T-shaped bearing plate 2 fixed to the upper end of the fixing platform 3. Through the coordinated work of the reciprocating moving mechanism and the extension structure, the clamping mechanism can firmly clamp both sides of the photovoltaic module. Compared with traditional clamping mechanisms, it can more fully fix the photovoltaic module and prevent it from shaking or shifting during the testing process, thereby ensuring the accuracy of the testing results.

[0028] The reciprocating movement mechanism includes forward and reverse screws 17 rotatably connected between opposite side walls inside the opening 15. A servo motor 9 is fixed on one side of the fixed platform 3. The power of the servo motor 9 is 0.5kW-1.5kW. The photovoltaic module weighs 10-20kg. The power of the servo motor 9 can meet the driving requirements.

[0029] The output shaft of the servo motor 9 is connected to one end of the forward and reverse screw 17. Combined with the forward and reverse screw drive, the screw lead is 25-45mm. When the speed is 1500r / min, the moving block moves at a speed of about 7.5-15mm / s, which can meet the stability requirements of photovoltaic module clamping.

[0030] Both ends of the forward and reverse screws 17 are threaded with movable blocks 16. The movable blocks 16 are engaged in the opening 15. When the servo motor 9 drives it to rotate, the movable blocks 16 can achieve reverse linear motion. The movable blocks 16 are engaged in the opening 15, which not only ensures the stability of its movement, but also prevents the movable blocks 16 from deviating or shaking during the movement, thus ensuring the precise operation of the entire mechanism.

[0031] The extension structure includes mounting blocks 8 fixed at both ends of a movable block 16 on the same side. A folding frame 10 is rotatably connected to one end of each of the two mounting blocks 8 on the same side. A guide rail 14 is fixed to one side of the support plate 12, and movable blocks 11 are engaged on both sides of the guide rail 14. One end of the folding frame 10 is rotatably connected between the two movable blocks 11. The design of the folding frame 10 gives the extension structure good telescoping and expandability. When the movable block 16 moves, the mounting blocks 8 drive the folding frame 10 to move. The rotatable connection of the folding frame 10 allows it to flexibly unfold and retract. The cooperation between the guide rail 14 and the movable blocks 11 further ensures the smoothness and accuracy of the movement of the support plate 12. The movable blocks 11 are engaged on the guide rail 14 and can slide along the guide rail 14, preventing the support plate 12 from jamming or shifting during movement, thus ensuring the smooth operation of the entire extension structure.

[0032] Slider 5 is fixed on both sides of the lower end of the support plate 12. The upper end of the base plate 7 is provided with four sliding grooves 6. One slider 5 on the same side is engaged in one sliding groove 6 on the same side. The slider 5 is engaged in the sliding groove 6, which provides a stable guiding effect for the movement of the support plate 12. This not only reduces frictional resistance and improves the smoothness of the movement of the support plate 12, but also ensures the stability of the support plate 12 during the movement. At the same time, the design of the sliding groove 6 can also limit the range of motion of the slider 5, preventing the support plate 12 from moving excessively or detaching from the base plate 7.

[0033] The clamping mechanism includes a support plate 4 fixed to the upper end of the bearing plate 12, and a clamping plate 1 fixed to the upper end of the support plate 4. The support plate 4 provides stable support for the clamping plate 1, ensuring that the clamping plate 1 will not shake or deform during the clamping process.

[0034] Multiple pressure sensors 13 are evenly spaced on one side of the clamping plate 1. When the pressure sensor detects that the clamping force reaches the set threshold of 50-100N, the pulse control realizes closed-loop control through encoder feedback, the motor stops immediately and locks the position to prevent over-clamping and damage to the components.

[0035] When clamping photovoltaic modules, the information fed back by pressure sensor 13 can precisely control the clamping force, avoiding damage to the photovoltaic modules due to excessive clamping force, or loosening of the photovoltaic modules during the testing process due to insufficient clamping force, which would affect the accuracy of the testing results.

[0036] A rubber pad is installed on the upper end of the T-shaped support plate 2. The rubber pad can buffer and protect the photovoltaic module, prevent its surface from being scratched. At the same time, the rubber pad can also increase the friction between the photovoltaic module and the T-shaped support plate 2, prevent the photovoltaic module from sliding during placement, and ensure the stability of the photovoltaic module placement.

[0037] In this invention, when testing photovoltaic modules:

[0038] 1. Preparation: Install the base plate 7 at the lower end of the testing mechanism to ensure the stability of the entire fixing frame. Carefully place the photovoltaic module to be tested on the upper end of the T-shaped support plate 2. The rubber pad installed on the T-shaped support plate 2 can buffer and protect the photovoltaic module to prevent its surface from being scratched.

[0039] 2. Start the reciprocating movement mechanism: Turn on the servo motor 9. The output shaft of the servo motor 9 drives the forward and reverse screws 17 to rotate. Since the threads at both ends of the forward and reverse screws 17 are in opposite directions, when the forward and reverse screws 17 rotate, the movable blocks 16 at both ends will move in opposite directions in a straight line within the opening 15. The movable blocks 16 are engaged within the opening 15 to ensure the stability of its movement.

[0040] 3. Extended structure movement: As the movable block 16 moves, the mounting blocks 8 fixed at both ends of the movable block 16 also move. The mounting blocks 8 drive the folding frame 10 to move. One end of the folding frame 10 is rotatably connected between the movable blocks 11, and the movable blocks 11 are engaged with the guide rail 14. Therefore, the movement of the folding frame 10 pushes the movable blocks 11 to slide on the guide rail 14, thereby driving the support plate 12 to move. The slider 5 at the lower end of the support plate 12 slides in the groove 6 on the base plate 7, ensuring the stability of the movement of the support plate 12.

[0041] 4. Clamping the photovoltaic module: The movement of the support plate 12 causes the clamping mechanism fixed on it to move closer to the photovoltaic module. The clamping plate 1 in the clamping mechanism gradually contacts both sides of the photovoltaic module. The pressure sensor 13 can monitor the magnitude of the clamping force in real time. When the pressure reaches a suitable value, it indicates that the photovoltaic module has been firmly clamped. At this time, subsequent testing can be carried out, and the servo motor 9 stops operating. During the clamping process of the photovoltaic module, pay close attention to the data changes of the pressure sensor 13. By connecting the display device of the pressure sensor 13, observe the magnitude of the clamping force in real time. According to the material and specifications of the photovoltaic module, a suitable clamping force range is preset. When the clamping force displayed by the pressure sensor 13 reaches the set value, it indicates that the photovoltaic module has been firmly clamped. At this time, stop the operation of the servo motor 9 to avoid over-clamping and damage to the photovoltaic module. After completing the testing, slowly release the clamping force and remove the photovoltaic module from the clamping mechanism. The operation process is gentle to prevent secondary damage to the photovoltaic module.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
