[0002] A high-speed tin coating machine refers to a mechanical device mainly used for tin plating on products such as copper bars, aluminum bars, current transformers, and electrical connection terminals to achieve the purposes of anti-corrosion, improving electrical conductivity and welding performance. A photovoltaic solder tape is a welding material used for connecting battery cells in photovoltaic modules, playing an important role in conducting and aggregating electricity. A high-speed tin coating machine is required during the processing of photovoltaic solder tapes, and a wire break protection structure is needed during the use of the high-speed tin coating machine for photovoltaic solder tapes to improve the use effect of the high-speed tin coating machine for photovoltaic solder tapes. For example:

[0038] Please refer to Figures 1-9, the present invention provides a technical solution: a high-speed tin coating machine for photovoltaic solder tapes with wire-breaking protection, including: a feeding roller 2 is fixedly installed on the left side of the upper end of the machine body 1, and a tin coating furnace 18 is fixedly installed on the right side of the upper end of the machine body 1.

And a connecting disk 29 is connected to the outside of the mounting rod 30. A photovoltaic solder tape body 4 is connected to the outside of the solder tape connecting roller 3, and a mounting roller 5 is movably connected to the lower left side of the photovoltaic solder tape body 4. A moving roller 6 is arranged inside the mounting roller 5, and a connecting rod 33 is connected to the outside of the inner and outer sides of the moving roller 6. A first spring 7 is fixedly arranged on the lower side of the connecting rod 33, and a connecting rod 32 is connected to the front upper side of the upper end of the connecting rod 33. And a connecting plate 28 is connected to the outside of the connecting rod 32. Install the solder tape connecting roller 3 outside the feeding roller 2, then install the connecting disk 29 at the front end of the feeding roller 2, and rotate the mounting rod 30 to connect the mounting rod 30 in the middle side of the connecting disk 29, so that the mounting rod 30 is connected on the front side of the feeding roller 2, which is convenient for limiting the solder tape connecting roller 3. Then, after passing the photovoltaic solder tape body 4 through the upper side of the mounting roller 5 and the lower side of the moving roller 6, it is inserted into the inside of the flux box 8, so that the photovoltaic solder tape body 4 passes through the upper side of the support roller 21 and then passes through the lower side of the immersion roller 10. At the same time, the photovoltaic solder tape body 4 also passes through the inside of the scraper 27, so that the photovoltaic solder tape body 4 passes through the upper side of the connecting roller 12 and passes through the middle side of the mounting plate 11, and further makes the photovoltaic solder tape body 4 pass through the upper side of the adjusting roller 14, and makes the photovoltaic solder tape body 4 pass through the tin coating furnace 18 and the fixing plate 19, so that the photovoltaic solder tape body 4 is installed outside the collecting roller. Rotate the connecting rod 32 to connect the connecting rod 32 on the front upper side of the connecting plate 28, so that the connecting rod 33 connected to the connecting rod 32 slides downward, and further makes the connecting rod 33 drive the moving roller 6 to slide downward, so that the connecting rod 33 drives the first spring 7 to be compressed, so that the distance between the moving roller 6 and the mounting roller 5 changes, and further makes the photovoltaic solder tape body 4 on the outside of the mounting roller 5 and the outside of the moving roller 6 be tightened, which is convenient for adjusting the tension of the photovoltaic solder tape body 4;

[0039] The flux box 8 is fixedly installed on the upper middle side of the machine body 1, and a support roller 21 is movably installed on the upper side inside the flux box 8. A dipping roller 10 is movably connected to the lower side inside the flux box 8, and a uniform coating structure is fixedly installed on the outer side inside the flux box 8. The upper end of the flux box 8 is connected to a cover plate 9, and a fixing rod 22 is connected to the outer side of the middle of the cover plate 9. The photovoltaic solder tape body 4 is introduced into the lower side inside the flux box 8 through the dipping roller 10 for flux dipping, so that the photovoltaic solder tape body 4 moves to the inner side of the scraper 27, so that the scraper 27 scrapes off the excess flux on the outer side of the photovoltaic solder tape body 4, facilitating the uniform coating of the flux on the surface of the photovoltaic solder tape body 4. Then, by rotating the fixing rod 22, the fixing rod 22 is connected to the outer side of the middle of the cover plate 9, so that the fixing rod 22 slides outward on the outer side of the middle of the cover plate 9, and further the fixing rod 22 separates from the outer side of the upper end of the flux box 8, so that the cover plate 9 separates from the outer side of the upper end of the flux box 8. Then, the uniform coating structure is pulled upward, so that the uniform coating structure separates inside the flux box 8, facilitating the replacement of the scraper 27. Then, the refrigerator 20 fixedly arranged inside the fixing plate 19 cools the outer side of the photovoltaic solder tape body 4;

[0040] The second spring 15 is fixedly arranged in the middle side inside the machine body 1, and a connecting block 16 is fixedly installed on the upper side of the second spring 15. A moving block 17 is fixedly installed on the left side of the connecting block 16, and a pushing block 23 is movably connected to the upper right side of the moving block 17. A limiting block 24 is fixedly installed on the middle right side of the pushing block 23, and an elastic member is arranged on the upper right side of the pushing block 23. A moving rod 13 is fixedly installed on the upper middle side of the connecting block 16, and a mounting plate 11 is movably connected to the outer side of the moving rod 13. A moving plate 31 is fixedly installed on the upper end of the moving rod 13, and a third spring 34 is fixedly arranged on the lower side of the moving plate 31. An adjusting roller 14 is movably connected to the inner side of the moving plate 31, and a connecting roller 12 is arranged on the outer side of the adjusting roller 14. When the photovoltaic solder tape body 4 breaks, the pressure of the photovoltaic solder tape body 4 on the adjusting roller 14 downward disappears, so that the third spring 34 drives the moving plate 31 to slide upward, and further the second spring 15 drives the connecting block 16 to slide upward, so that the moving plate 31 drives the adjusting roller 14 to slide upward, so that the connecting block 16 drives the moving block 17 to slide upward, and further the connecting block 16 and the connecting roller 12 clamp the photovoltaic solder tape body 4, so that the moving block 17 pushes the pushing block 23 to slide to the right inside the mounting plate 11, so that the moving block 17 drives the limiting block 24 to slide to the right, and further the moving block 17 drives the elastic member arranged inside the mounting plate 11 to be compressed, so that the limiting block 24 and the mounting plate 11 clamp the photovoltaic solder tape body 4, facilitating the wire break protection of the photovoltaic solder tape body 4.

[0041] When using this high-speed tin coating machine for photovoltaic solder tape with wire break protection, specifically asFigure 3 and Figure 4 In Figure 4 , the solder tape connecting roller 3 is snap-fitted and installed on the outside of the feeding roller 2, and then the connecting plate 29 is fitted and installed at the front end of the feeding roller 2. The mounting rod 30 is connected to the feeding roller 2 by means of a thread, and the feeding roller 2 and the connecting plate 29 are connected by a fitting method. Rotate the mounting rod 30 so that the mounting rod 30 is threadedly connected in the middle side of the connecting plate 29, so that the mounting rod 30 is threadedly connected on the front side of the feeding roller 2, which is convenient for limiting the solder tape connecting roller 3. Then, the photovoltaic solder tape body 4 is respectively passed through the upper side of the mounting roller 5 and the lower side of the moving roller 6, and then passed into the inside of the flux box 8, so that the photovoltaic solder tape body 4 passes through the upper side of the support roller 21 and then passes through the lower side of the immersion roller 10. At the same time, the photovoltaic solder tape body 4 also passes through the inside of the scraper 27, so that the photovoltaic solder tape body 4 passes through the upper side of the connecting roller 12 and passes through the middle side of the mounting plate 11, and then the photovoltaic solder tape body 4 passes through the upper side of the adjusting roller 14, and the photovoltaic solder tape body 4 passes through the tinning furnace 18 and the fixing plate 19, so that the photovoltaic solder tape body 4 is installed on the outside of the collecting roller. Specifically, as shown in Figure 5 、 Figure 6 and Figure 7 In Figure 7 , the connecting rod 32 is connected to the connecting plate 28 by means of a thread, and the connecting rod 32 is connected to the connecting rod 33 through a bearing. Rotate the connecting rod 32 so that the connecting rod 32 is threadedly connected on the front upper side of the connecting plate 28, so that the connecting rod 33 connected to the connecting rod 32 through the bearing slides downward, and then the connecting rod 33 drives the moving roller 6 to slide downward. The connecting rod 33 is connected to the connecting plate 28 by a sliding method, and the connecting rod 33 is connected to the moving roller 6 by a rotating method, so that the connecting rod 33 drives the first spring 7 to be compressed, so that the distance between the moving roller 6 and the mounting roller 5 changes, and then the photovoltaic solder tape body 4 on the outside of the mounting roller 5 and the outside of the moving roller 6 is tightened, which is convenient for adjusting the tension of the photovoltaic solder tape body 4;

[0042] Specifically, as shown in Figure 2 、 Figure 3 and Figure 8In this case, the photovoltaic solder strip body 4 is introduced into the lower side inside the flux box 8 through the soaking roller 10 for flux soaking. The squeegee 27 is connected to the photovoltaic solder strip body 4 in a fitting manner, and the squeegee 27 is symmetrically distributed about the center line of the photovoltaic solder strip body 4, so that the photovoltaic solder strip body 4 moves to the inner side of the squeegee 27, thereby enabling the squeegee 27 to scrape off the excess flux on the outer side of the photovoltaic solder strip body 4, facilitating the uniform application of flux on the surface of the photovoltaic solder strip body 4. The fixing rod 22 is connected to the flux box 8 in a threaded manner, and the fixing rod 22 is symmetrically distributed about the center line of the cover plate 9. By rotating the fixing rod 22, the fixing rod 22 is threadedly connected to the outer side of the middle part of the cover plate 9, so that the fixing rod 22 slides outward on the outer side of the middle part of the cover plate 9, and then the fixing rod 22 is separated from the outer side of the upper end of the flux box 8, and the cover plate 9 is separated from the outer side of the upper end of the flux box 8. The limiting plate 26 is connected to the squeegee 27 in a clamping manner, and the vertical cross-sectional shape of the limiting plate 26 is an "L" - shaped structure. By pulling the limiting plate 26 upward, the limiting plate 26 drives the limiting rod 36 to slide upward on the outer side of the mounting block 25, so that the limiting rod 36 drives the mounting spring 35 to be compressed, and then the limiting plate 26 is separated from the upper side of the outer side of the squeegee 27. By pulling the squeegee 27 forward, the rear side of the squeegee 27 is separated from the upper side of the mounting block 25, so as to pull the rear side of the squeegee 27 upward, and then the front side of the squeegee 27 is separated from the upper side of the mounting block 25, and the squeegee 27 is separated inside the flux box 8, facilitating the replacement of the squeegee 27. Then, the cooler 20 fixedly arranged inside the fixing plate 19 cools the outer side of the photovoltaic solder strip body 4;

[0043] Specifically, such as Figure 1 、 Figure 2 and Figure 9In the case where the photovoltaic solder strip body 4 breaks, the moving rod 13 is connected to the mounting plate 11 in a sliding manner, so that the downward pressure of the photovoltaic solder strip body 4 on the adjusting roller 14 disappears. As a result, the third spring 34 drives the moving plate 31 to slide upward, and then the moving plate 31 drives the moving rod 13 to slide upward in the middle of the mounting plate 11, so that the second spring 15 drives the connecting block 16 to slide upward. Thus, the moving plate 31 drives the adjusting roller 14 to slide upward, and then the connecting block 16 drives the moving block 17 to slide upward, so that the connecting block 16 and the connecting roller 12 clamp the photovoltaic solder strip body 4. The limiting block 24 is connected to the mounting plate 11 in a sliding manner, and the vertical cross-sectional shape of the limiting block 24 is a "T" - shaped structure. Therefore, the moving block 17 pushes the pushing block 23 to slide to the right inside the mounting plate 11, and then the moving block 17 drives the limiting block 24 to slide to the right, so that the moving block 17 drives the elastic member arranged inside the mounting plate 11 to be compressed. Thus, the limiting block 24 and the mounting plate 11 clamp the photovoltaic solder strip body 4, which is convenient for the disconnection protection of the photovoltaic solder strip body 4.
