Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell production, in particular to a photovoltaic cell sheet drying structure. Background Art

[0002] With the rapid development of the photovoltaic industry, new manufacturing processes are constantly emerging to increase production capacity and reduce costs, but these processes also bring new problems and challenges. This is particularly true during the wet process of silicon wafer manufacturing, where the moisture drying problem is particularly prominent. After certain advanced processes (such as PERC and Topcon), silicon wafers are susceptible to the so-called "pool effect" and "watermark" problems during the drying phase. These problems not only affect the appearance quality of the silicon wafers, but more importantly, they can also cause microcracks or thermal stress concentrations during the production process, thereby affecting the electrical performance and service life of the silicon wafers, ultimately leading to reduced production efficiency and increased production costs.

[0003] Therefore, a photovoltaic cell drying structure is proposed. Utility Model Content

[0024] like Figures 1 to 4As shown, a photovoltaic cell drying structure includes a first support frame 1 and a second support frame 2. The surfaces of the first support frame 1 and the second support frame 2 are both rotatably connected with a plurality of solid wheels 3 for conveying photovoltaic cells. The surfaces of the first support frame 1 and the second support frame 2 are both provided with a transmission drive mechanism 4 for controlling the rotation of the solid wheel 3. A third support frame 7 is provided between the first support frame 1 and the second support frame 2. The surface of the third support frame 7 is installed with a flipping mechanism 5 for flipping the photovoltaic cell from the surface of the left solid wheel 3 to the surface of the right solid wheel 3. The surface of the second support frame 2 is installed with an air knife assembly 6 for cleaning moisture from the surface of the photovoltaic cell. More specifically, the photovoltaic panel is placed on the surface of the left solid wheel 3, and the solid wheel 3 is controlled to rotate by the transmission drive mechanism 4 to transport the photovoltaic sheet. The photovoltaic sheet will enter the surface of the flipping mechanism 5, and the photovoltaic sheet will be driven to rotate by the flipping mechanism 5. During the rotation, the moisture on the surface of the photovoltaic sheet will flow under the action of gravity, leaving only a small amount of adhering moisture. Then the flipping mechanism 5 flips the photovoltaic sheet to the surface of the right solid wheel 3, and the photovoltaic sheet continues to be transported by the right transmission drive mechanism 4 and the solid wheel 3. The wind knife assembly 6 is operated to blow air on the surface of the photovoltaic sheet to dry the adhering moisture.

[0025] The transmission drive mechanism 4 includes a first motor 401, and the first motor 401 is fixedly mounted on the surface of the first support frame 1 and the second support frame 2. The output end of the first motor 401 is fixedly connected to the first rotating shaft 402, and the output end of the first rotating shaft 402 is fixedly connected to the first rotating shaft 402. The end of the first rotating shaft 402 is fixedly connected to the driving sprocket 403, and the surface of the driving sprocket 403 is meshed with a driving chain 404. The ends of the multiple solid wheels 3 are all fixedly connected to the driven sprockets 405, and the adjacent driven sprockets 405 are meshed with a transmission chain 406. The driving chain 404 is meshed with the surface of one of the driven sprockets 405. It should be noted that the first rotating shaft 402 and the driving sprocket 403 are driven to rotate by the first motor 401. Under the transmission action of the driving chain 404, the driven sprocket 405 will be driven to rotate, thereby controlling the rotation of the solid wheels 3. Through the synchronous rotation of multiple solid wheels 3, photovoltaic panels can be transported.

[0026] The flipping mechanism 5 includes a second motor 501, which is fixedly mounted on the surface of the third support frame 7. The output end of the second motor 501 is fixedly connected to a second rotating shaft 502, and the surface of the second rotating shaft 502 is fixedly connected to a plurality of supporting plates 503. More specifically, the second motor 501 drives the second rotating shaft 502 to rotate, which can drive the supporting plates 503 to rotate. When a group of supporting plates 503 rotates to be flush with the solid wheel 3, the second motor 501 stops running, and the left solid wheel 3 feeds most of the photovoltaic panels onto the surface of the supporting plates 503. The second motor 501 continues to run, driving the photovoltaic panels to rotate until the second motor 501 is flush with the surface of the right solid wheel 3. Under the action of the friction force of the right solid wheel 3, the photovoltaic panels will be pulled away from the surface of the supporting plates 503, and the photovoltaic panels will be flipped over. During the rotation of the photovoltaic panels, the liquid on the photovoltaic panels will flow away due to gravity, leaving only a small amount adhering to the surface.

[0027] Buffer pads 504 are fixedly connected to both sides of the carrier plate 503, and the buffer pads 504 are made of rubber. It should be noted that by providing the rubber buffer pads 504, the photovoltaic panels can be cushioned during the rotation process to prevent the photovoltaic panels from being damaged due to collision.

[0028] The air knife assembly 6 includes a fan 601, which is fixedly mounted on the surface of the second support frame 2. The air outlet of the fan 601 is fixedly connected to a first connecting pipe 602. The surface of the first connecting pipe 602 is fixedly connected to an air knife box 603. There are two sets of air knife boxes 603, and the two sets of air knife boxes 603 are respectively located on the upper and lower sides of the photovoltaic panel. More specifically, the air is blown by the fan 601, and the air is output through the first connecting pipe 602 and the air knife box 603, which purges the moisture on the surface of the photovoltaic panel and dries and cleans the residual moisture on the photovoltaic panel.

[0029] The wind knife assembly 6 also includes a second connecting pipe 604, which is fixedly connected to the air outlet end of the fan 601. The end of the second connecting pipe 604 is fixedly connected to an air outlet cover 605. A support rod 606 is fixedly connected between the air outlet cover 605 and the third support frame 7. It should be noted that the fan 601 simultaneously sends high-speed air into the second connecting pipe 604 and outputs the high-speed air through the air outlet cover 605 to blow air onto the photovoltaic panels on the surface of the flip mechanism 5, accelerating the outflow of moisture from the photovoltaic panels.

[0030] In summary: the photovoltaic panel is placed on the surface of the solid wheel 3 on the left, and the solid wheel 3 is controlled to rotate by the transmission drive mechanism 4 to transport the photovoltaic sheet. The photovoltaic sheet will enter the surface of the flipping mechanism 5, and the photovoltaic sheet will be driven to rotate by the flipping mechanism 5. During the rotation, the moisture on the surface of the photovoltaic sheet will flow under the action of gravity, leaving only a small amount of adhering moisture. Then the flipping mechanism 5 flips the photovoltaic sheet to the surface of the solid wheel 3 on the right, and the photovoltaic sheet is continued to be transported by the right transmission drive mechanism 4 and the solid wheel 3. The wind knife assembly 6 is operated to blow air on the surface of the photovoltaic sheet to dry the adhering moisture. During use, it is easy to automatically clean the moisture remaining in the photovoltaic sheet manufacturing process, effectively improving the drying efficiency of the photovoltaic sheet and avoiding moisture residue affecting the quality of the photovoltaic sheet.
