[0002] Photovoltaic panel components are a type of power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials.

[0003] Compared with traditional power generation methods, photovoltaic modules have certain economic advantages. Since solar energy is free, once the system is installed, the cost of power generation will be greatly reduced. Using photovoltaic modules to generate electricity can also reduce the use of fossil energy such as coal and fossil fuels, thereby reducing the emission of greenhouse gases such as carbon dioxide and protecting the environment.

[0004] Photovoltaic modules need to be packaged and transported after production. During the packaging process, individual photovoltaic modules are first wrapped to protect the module surface from scratches or damage by other external forces. The packaged photovoltaic modules are then properly fixed with packing tape to ensure that the modules will not move or slide during transportation.

[0005] As the demand for photovoltaic modules grows, the quality of module packaging becomes increasingly important. Currently, there are two types of strapping tapes: manual and machine. However, quality issues after packaging require manual sampling. The sampling standard requires one hand to hold a ruler and the other hand to use a dynamometer to measure the strength of the strapping tape. Currently, manual testing is extremely inconvenient, and it is even impossible to control the standard length of 5cm stretched, resulting in inaccurate test results and affecting the quality test results of the strapping tape.

[0051] like Figure 1~Figure 4 As shown, this embodiment proposes a dynamometer device for measuring the tightening force of the photovoltaic module packaging belt, including a support plate 1, a measuring mechanism, a tension clamp 2, a positioning mechanism, a positioning plate 3, a moving block 4 and a protruding rod 5.

The worker fixes the left hand and measures with the right hand, which is more convenient, quick and efficient. The positioning mechanism is used to fix the appropriate measurement standard, and there is no need to manually measure the length when pulling the dynamometer 6. Among them, the device adopts a ram horn fixing form, which has a stable reference surface for relative measurement, and the ram horn fixing plate 9 has a concave space reserved at the head, which ensures that the strapping tape is not scratched or blocked when it is pulled up during measurement. There are also scale lines on the upper surface of the ram horn fixing plate 9, which is convenient for identifying the measuring distance. At the same time, the measuring distance can be selected according to needs.

[0052] Among them, Figure 1 and Figure 2 As shown, the measuring mechanism includes a dynamometer 6, a sliding component and a fixed component. The dynamometer 6 is fixedly connected in the tension clamp 2, the sliding component is installed at the bottom end of the tension clamp 2, and the fixed component is installed at one end of the support plate 1. The sliding mechanism is used to slide the dynamometer 6, and the fixed component is used to make the fixed end close to the measuring part. The sliding mechanism and the tension clamp 2 cooperate to pull the dynamometer 6, making it more convenient for workers to operate.

[0053] Secondly, if Figure 2 As shown, the sliding assembly includes a sliding rail 7 and a sliding block 8. The sliding rail 7 is fixedly connected to the support plate 1, and the sliding block 8 is fixedly connected to the bottom end of the tension clamp 2. The sliding block 8 is slidably connected to the sliding rail 7. When the sliding assembly pulls the tension clamp 2, the sliding block 8 slides on the sliding rail 7, driving the tension meter 6 to measure the tension.

[0054] Again, if Figure 1 and Figure 2 As shown, the fixing assembly includes a horn fixing plate 9 and a fixing rod 10. The horn fixing plate 9 is fixedly connected to one end of the support plate 1, and the fixing rod 10 is fixedly connected to the bottom end of the support plate 1. The lower part of the horn fixing plate 9 is provided with a fixing rod 10, which is convenient for forming a stable triangular structure with the horns on the head.

[0055] Among them, Figure 3 As shown, the positioning mechanism includes a limit assembly and an adjustment assembly. The limit assembly is mounted on the positioning plate 3 , and the adjustment assembly is mounted on the positioning plate 3 .

[0056] Secondly, if Figure 3 As shown, the limit assembly includes a limit slot 11, a limit block 12 and a standard assembly. The limit slot 11 is provided on the movable block 4. The limit block 12 is slidably connected in the limit slot 11. A groove is provided on the outer wall of the limit block 12. The protruding rod 5 matches the shape of the groove. The standard assembly is installed on the limit block 12. The standard assembly is used to lock the tension clamp 2 when the dynamometer 6 reaches the standard measurement length so that it cannot continue to move. Frequent measurements and readings are not required. The limit slot 11 and the limit block 12 cooperate to control the working state of the standard assembly.

[0057] Again, if Figure 3 As shown, the standard component includes a positioning hole 13, a spring telescopic rod 14 and an inclined surface 15. There are two positioning holes 13, which are respectively opened on both sides of the tension clamp 2. There are two spring telescopic rods 14, which are respectively fixedly connected to the moving block 4. An inclined surface 15 is opened on the output end of each spring telescopic rod 14. The inclined surface 15 at the output end of the spring telescopic rod 14 rubs and slides on the outer wall of the tension clamp 2. When the inclined surface 15 enters the positioning hole 13, the dynamometer 6 pulls the standard measurement distance, and the measurement efficiency is high.

[0058] Among them, Figure 3 As shown, the adjustment component includes a fixing hole 16 and a positioning rod 17. There are multiple fixing holes 16, and the multiple fixing holes 16 are divided into two groups. Each positioning plate 3 is provided with a group of fixing holes 16. The positioning rod 17 is fixedly connected to the bottom end of the moving block 4, and the positioning rod 17 is slidably connected in the fixing hole 16. The adjustment component adjusts different measurement standard distances by inserting the adjusting positioning rod 17 into different fixing holes 16.

[0059] Secondly, if Figure 1 As shown, the two spring telescopic rods 14 and the two positioning holes 13 are on the same horizontal plane, and the two positioning holes 13 cooperate with the output ends of the two spring telescopic rods 14. The spring telescopic rods 14 and the positioning holes 13 are on the same horizontal plane. When the dynamometer 6 is pulled to the standard measurement distance, the output ends of the spring telescopic rods 14 will be smoothly inserted into the positioning holes 13.

[0060] Finally, if Figure 2 As shown, the distance between every two fixing holes 16 is the same, which is convenient for calculating and measuring the standard distance.

[0061] In this embodiment, when measuring the strength of the strapping tape, first, the horn fixing plate 9 and the fixing rod 10 are pressed against the packaged items, the dynamometer 6 is hung on the strapping tape, and the positioning rod 17 is inserted into the appropriate fixing hole 16 according to the measurement standard. At this time, the limit block 12 is pushed forward, and the output end of the spring telescopic rod 14 is extended out of the moving block 4. Then, the output end of the spring telescopic rod 14 slides on the outer wall of the tension clamp 2, and the dynamometer 6 is pulled. After reaching the measurement standard, under the action of the spring, the output end of the spring telescopic rod 14 bounces into the positioning hole 13. At this time, the tightening force of the strapping tape can be obtained by observing the scale and reading the data of the dynamometer 6.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
