Description

Technical Field

[0001] This utility model relates to the field of photovoltaic coating templates, and in particular to a photovoltaic thin film module coating template with adjustable coating area. Background Technology

[0002] Photovoltaic thin-film modules are a new type of solar cell module. They use thin-film technology to deposit photovoltaic materials onto a substrate, and are characterized by being lightweight, flexible, and mass-producible. Compared with traditional crystalline silicon photovoltaic modules, thin-film modules have lower production costs and can perform better under low light conditions. They are not only suitable for large-scale photovoltaic power plants, but also for building integration, transportation, and other fields. Photovoltaic thin-film modules typically consist of a three-layer structure: a substrate, a photovoltaic material layer, and a transparent conductive layer. These modules can effectively capture sunlight and convert it into electrical energy.

[0003] Thin-film modules have high temperature tolerance, making them suitable for high-temperature environments. Their flexibility also makes them adaptable to special shapes or spaces with limited space. Although their conversion efficiency is lower than that of crystalline silicon modules, with continuous technological advancements, the efficiency and durability of thin-film photovoltaic technology have been significantly improved. Photovoltaic thin-film modules represent the innovation trend of the photovoltaic industry, especially in distributed power generation and building-integrated photovoltaics applications, where they have demonstrated unique advantages.

[0004] Photovoltaic thin-film module coating templates are important tools used in the production process of thin-film photovoltaic cells. By uniformly depositing photovoltaic material layers on the substrate surface, the template is made of high-precision materials to ensure the uniformity and quality of the thin film and optimize photoelectric conversion efficiency. However, in traditional coating templates, because the template is customized, the position of the coating area cannot be adjusted arbitrarily according to production needs, resulting in high costs. To address this issue, a photovoltaic thin-film module coating template with adjustable coating area is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a photovoltaic thin-film module coating template with adjustable coating area, which aims to improve the problem of high cost in traditional coating templates, which cannot be adjusted according to production needs because the template is customized.

[0007] The shielding assembly includes four inner shells, which are respectively fixedly connected to the outside of the frame.

[0024] 2.

The sliding grooves 3 are used to limit the direction of movement of the sliding rods 4. The sliding rods 4 are used to pull the shielding film 8 to move. The insertion holes 5 are used to cooperate with the insertion rods 14 to fix the sliding rods 4 on the frame 1. A shielding component is installed inside the frame 1, and a fixing component is installed on the upper side of the sliding rods 4.

The rotating rod 7 is used to drive the springs 9 to store power or to drive the shielding film 8 to rewind. The shielding film 8 is used to shield the areas of the photovoltaic thin-film module that do not require coating. The rotating rod 7 is used to drive the rotating rod 7 to rotate, causing the shielding film 8 to rewind. The springs 9 are fixedly connected to the inner wall of the inner shells 6 to keep them stable. The shielding film 8 is fixedly connected to the outside of a sliding rod 4, allowing the sliding rod 4 to pull the shielding film 8 to unfold. The shielding film 8 is slidably connected to the inside of the inner shells 6 and to the inside of the frame 1, restricting the direction of movement of the shielding film 8.

[0037] Reference Figures 5-7The fixing assembly includes two housings 10. The bottom of the housing 10 is fixedly connected to the top of the slide bar 4. A spring 11 is fixedly connected to the inner wall of the housing 10. A slide plate 12 is fixedly connected to the inner side of the spring 11. A lever 13 is fixedly connected to the outer side of the slide plate 12. A plug rod 14 is fixedly connected to the inner side of the slide plate 12. A stop block 15 is slidably connected inside the housing 10. A lever 16 is fixedly connected to the outer side of the stop block 15. The housing 10 is used to connect and protect the internal parts. The spring 11 is used to push the slide plate 12 to reset. The slide plate 12 is used to drive the plug rod 14 to move synchronously. The lever 13 is used to facilitate manual movement of the slide plate 12. The plug rod 14 is used to insert into the socket 5 to fix the slide bar 4 on the frame 1. The stop block 15 is slidably connected to the inner wall of the housing 10. 5 is used to block the insertion rod 14 to prevent it from automatically resetting. The lever 16 is used to facilitate manual movement of the stop block 15. The slide plate 12 is externally slidably connected to the inner wall of the housing 10. The lever 13 is externally slidably connected to the inside of the housing 10. The insertion rod 14 is externally slidably connected to the inside of the housing 10. The lever 16 is externally slidably connected to the inside of the housing 10. The housing 10 simultaneously restricts the movement direction of the slide plate 12, lever 13, insertion rod 14 and lever 16. The insertion rod 14 is externally inserted into the insertion hole 5 to fix the slide rod 4. The stop block 15 and the insertion rod 14 abut against each other to prevent the insertion rod 14 from automatically resetting. The inner side of the housing 10 is slidably connected to the outside of the frame 1 to restrict the movement direction of the slide rod 4.

[0038] Working principle: When using this device to restrict the coating position of the photovoltaic thin-film module, first place the frame 1 on the photovoltaic thin-film module, and adjust the position of the slide bar 4 according to the size of the photovoltaic thin-film module or the position where coating is not required. By moving the lever 13, the slide plate 12 compresses the spring 11, causing the insertion rod 14 to retract into the housing 10 and disengage from the insertion hole 5. At the same time, the stop block 15 will automatically fall down to block the outlet of the insertion rod 14. At this time, the slide bar 4 is unlocked. Then, slide the slide bar 4 under the limit of the slide groove 3. At the same time, the slide bar 4 pulls the shielding film 8 to unfold and drives the rotating rod 7 to rotate to charge the spring 9. When the slide bar 4 moves to the appropriate position, pull the lever 16 upward to stop the stop block 15. When the insert rod 14 is disengaged, the spring 11 will instantly push the slide plate 12 to reset, causing the insert rod 14 to pop out and insert into the socket 5, fixing the slide rod 4 to the frame 1, thereby achieving rapid adjustment. At this time, the photovoltaic thin film module can be coated by the shielding film 8. The shielding film 8 blocks the excess material from the outside and will not cover other parts of the photovoltaic thin film module. When the coating work is finished, the lever 13 is turned again to disengage the insert rod 14 from the socket 5. At this time, the spring 9 will immediately drive the rotating rod 7 to rotate, causing the shielding film 8 to start to roll up. Pull the slide rod 4 to reset, and it can be stored. The operation is convenient and labor-saving, highly applicable, and effectively saves costs.
