Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solder ribbon processing technology, specifically to a tin coating equipment for photovoltaic solder ribbon processing. Background Technology

[0002] Photovoltaic solder ribbon, also known as tinned copper ribbon, is a core conductive material in photovoltaic modules. It plays a crucial role in the series or parallel connection of photovoltaic cells, directly affecting the output voltage, power, and power generation efficiency of the photovoltaic module. The preheated copper ribbon enters a photovoltaic solder ribbon tinning machine, where a tin alloy coating is formed on its surface through a tin plating process. After cooling, the tinned ribbon is finally collected, packaged, and the finished photovoltaic solder ribbon is obtained.

[0003] Existing tin-coating equipment for photovoltaic soldering ribbon processing is not convenient for rolling the surface tin layer flat, cannot achieve uniform coating, and cannot allow the cooled stainless steel guide roller to quickly absorb the heat from the copper ribbon, resulting in low cooling efficiency. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a tin coating equipment for photovoltaic soldering strip processing. The tin coating equipment for photovoltaic soldering strip processing facilitates the smoothing of the surface tin layer, achieving uniform coating. Furthermore, the cooled stainless steel guide rollers quickly absorb the heat from the copper strip, resulting in a significant cooling effect and improved production efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a tin coating equipment for photovoltaic soldering ribbon processing, including a photovoltaic soldering ribbon tin coating machine, a cooling box and a base. The photovoltaic soldering ribbon tin coating machine is installed on the top of the base by screws. Horizontal extension plates are installed on both sides of the photovoltaic soldering ribbon tin coating machine by bolts. A strip-shaped sliding hole is provided at one end of the horizontal extension plate and a sliding screw slides in the strip-shaped sliding hole. A cooling box is installed between the sliding screws through screw holes, and a sealing side plate is installed on one side of the cooling box by screws. A semiconductor refrigeration chip is installed on one side of the top of the sealing side plate through a mounting hole, and a temperature controller is installed on one end of the semiconductor refrigeration chip by screws.

[0006] The top and bottom of the cooling box are equipped with extension bolts through screw holes. One end of the extension bolt is connected to a connecting plate through a bearing. Both ends of the connecting plate are connected to U-shaped plates through support springs. Stainless steel guide rollers are connected inside the U-shaped plates through positioning shafts. The top of the photovoltaic ribbon tinning machine is equipped with a detachable top cover by screws.

[0007] By adopting the above technical solution, the tin coating equipment for photovoltaic soldering strip processing can easily roll the surface tin layer flat to achieve uniform coating. In addition, the cooled stainless steel guide rollers quickly absorb the heat from the copper strip, resulting in a significant cooling effect and improved production efficiency.

[0008] Specifically, the detection end of the temperature controller is located inside the cooling box, and the output end of the temperature controller is electrically connected to the input end of the semiconductor cooling chip via a wire.

[0009] Specifically, the cooling end of the semiconductor refrigeration chip is located inside the cooling chamber, while the heating end of the semiconductor refrigeration chip is located outside the cooling chamber.

[0010] Specifically, the sealing side plate and the other side of the cooling box are both provided with through openings, and the photovoltaic soldering strip coating machine is provided with an inlet and an outlet at both ends, respectively.

[0011] By adopting the above technical solution, the copper strip is conveyed from the feed port to the photovoltaic soldering strip tinning machine, so as to coat the outer surface of the copper strip with hot melt tin. The coated copper strip is output from the discharge port and enters the cooling box from one side through-hole and passes between two sets of stainless steel guide rollers, and finally outputs from the through-hole on the sealed side plate.

[0012] Specifically, a locking nut is fitted at the other end of the sliding screw, and the locking nut is located outside the strip-shaped sliding hole, with one end of the strip-shaped sliding hole being through.

[0013] By adopting the above technical solution, the locking nut is loosened to allow the sliding screw to slide in the strip-shaped sliding hole, which facilitates the adjustment of the distance between the cooling box and the photovoltaic soldering strip coating machine as needed. Furthermore, the strip-shaped sliding hole is designed to be open at one end, which facilitates the sliding screw to slide out of the strip-shaped sliding hole and makes it easy to disassemble the cooling box.

[0014] Specifically, a turntable is welded to the top of the extended bolt, and both ends of the support spring are connected to a connecting plate and a U-shaped plate respectively through positioning plates and screws.

[0015] The beneficial effects of this utility model are:

[0016] (1) The photovoltaic soldering strip processing tin coating equipment described in this utility model pre-turns on the semiconductor cooling chip and uses a temperature controller to automatically control the semiconductor cooling chip to keep the temperature in the cooling box constant and reduce the temperature of the stainless steel guide roller. The copper strip is transported from the feed port to the photovoltaic soldering strip tin coating machine to achieve hot melt tin coating on the outer surface of the copper strip. The coated copper strip is output from the discharge port and enters the cooling box from one side through port and passes between two sets of stainless steel guide rollers. Finally, it is output from the through port on the sealed side plate.

[0017] (2) The tin coating equipment for photovoltaic soldering strip processing described in this utility model drives the extended bolt to rotate by rotating the turntable, which causes the stainless steel guide rollers between the connecting plate and the U-shaped plate to move, thereby adjusting the distance between the two sets of stainless steel guide rollers, so that the stainless steel guide rollers are pressed onto the surface of the coated copper strip, which makes it easier to roll the surface metal tin layer flat and achieve uniform coating. In addition, the cooled stainless steel guide rollers quickly absorb the heat on the copper strip, resulting in a significant cooling effect and improved production efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To facilitate the smoothing and uniform coating of the tin layer on the surface of the photovoltaic soldering equipment, and to ensure that the cooled stainless steel guide roller 19 quickly absorbs the heat from the copper strip, resulting in a significant cooling effect and improved production efficiency, such as... Figure 1-3 As shown, the photovoltaic soldering ribbon processing tin coating equipment of this utility model includes a photovoltaic soldering ribbon tin coating machine 2, a cooling box 5 and a base 14. The photovoltaic soldering ribbon tin coating machine 2 is installed on the top of the base 14 by screws. Horizontal extension plates 15 are installed on both sides of the photovoltaic soldering ribbon tin coating machine 2 by bolts. One end of the horizontal extension plate 15 is provided with a strip-shaped sliding hole 11 and a sliding screw 13 slides in the strip-shaped sliding hole 11. The cooling box 5 is installed between the sliding screws 13 through screw holes, and a sealing side plate 6 is installed on one side of the cooling box 5 by screws. A semiconductor refrigeration chip 7 is installed on one side of the top of the sealing side plate 6 through a mounting hole, and a temperature controller 8 is installed on one end of the semiconductor refrigeration chip 7 by screws.

[0025] The top and bottom of the cooling box 5 are both equipped with extension bolts 4 through screw holes. One end of the extension bolt 4 is connected to a connecting plate 17 through a bearing. Both ends of the connecting plate 17 are connected to U-shaped plates 18 through support springs 20. Stainless steel guide rollers 19 are connected inside the U-shaped plates 18 through a positioning shaft. The top of the photovoltaic ribbon tinning machine 2 is equipped with a detachable top cover 1 through screws.

[0026] When in use, the tin coating equipment for photovoltaic soldering strip processing can easily roll the surface tin layer flat to achieve uniform coating. In addition, the cooled stainless steel guide roller 19 quickly absorbs the heat on the copper strip, resulting in a significant cooling effect and improved production efficiency.

[0027] For example, such as Figure 1 As shown, the present invention also includes a detection end of the temperature controller 8 located inside the cooling box 5, and an output end of the temperature controller 8 electrically connected to the input end of the semiconductor cooling chip 7 via a wire.

[0028] When in use, the semiconductor cooling chip 7 is turned on in advance, and the temperature controller 8 automatically controls the semiconductor cooling chip 7 to maintain a constant temperature and cool the inside of the cooling box 5.

[0029] For example, such as Figure 1 As shown, the present invention also includes a cooling end of the semiconductor refrigeration chip 7 located inside the cooling chamber 5 and a heating end of the semiconductor refrigeration chip 7 located outside the cooling chamber 5.

[0030] When in use, the cooling end of the semiconductor cooling chip 7 absorbs heat from inside the cooling box 5, and the heating end of the semiconductor cooling chip 7 releases heat to the outside of the cooling box 5.

[0031] For example, such as Figure 1 , 2 As shown, the present invention also includes a through-hole 9 on the other side of the sealing side plate 6 and the cooling box 5, and an inlet 16 and an outlet 10 on both ends of the photovoltaic soldering strip coating machine 2.

[0032] In use, the copper strip is fed from the feed port 16 into the photovoltaic soldering strip tinning machine 2, so that the outer surface of the copper strip is coated with hot melt tin. The coated copper strip is output from the discharge port 10 and enters the cooling box 5 from the through port 9 on one side and passes between the two sets of stainless steel guide rollers 19. Finally, it is output from the through port 9 on the sealed side plate 6.

[0033] For example, such as Figure 1 As shown, the present invention also includes a locking nut 12 sleeved on the other end of the sliding screw 13, and the locking nut 12 is located outside the strip-shaped sliding hole 11, with one end of the strip-shaped sliding hole 11 being through.

[0034] When in use, loosen the locking nut 12 to allow the sliding screw 13 to slide within the strip-shaped sliding hole 11, which facilitates adjusting the distance between the cooling box 5 and the photovoltaic soldering strip coating machine 2 as needed. The strip-shaped sliding hole 11 is also designed to be through at one end, which allows the sliding screw 13 to slide out of the strip-shaped sliding hole 11, making it easy to disassemble the cooling box 5.

[0035] For example, such as Figure 3As shown, the present invention also includes a turntable 3 welded to the top of the extended bolt 4, and both ends of the support spring 20 are respectively connected to a connecting plate 17 and a U-shaped plate 18 via positioning pieces 21 and screws.

[0036] During use, the positioning piece 21 and screws facilitate the installation and removal of the support spring 20.

[0037] When this utility model is in use, the semiconductor cooling chip 7 is turned on in advance, and the temperature controller 8 automatically controls the semiconductor cooling chip 7 to maintain a constant temperature in the cooling box 5, thereby reducing the temperature of the stainless steel guide roller 19. The copper strip is transported from the feed port 16 to the photovoltaic soldering strip coating machine 2 to achieve hot melt tin coating on the outer surface of the copper strip.

[0038] The coated copper strip is output from the outlet 10 and enters the cooling box 5 through the through-hole 9 on one side and passes between the two sets of stainless steel guide rollers 19. Finally, it is output from the through-hole 9 on the sealed side plate 6. By rotating the turntable 3, the extension bolt 4 is rotated, which causes the connecting plate 17 to move the stainless steel guide rollers 19 between the U-shaped plates 18, thereby adjusting the distance between the two sets of stainless steel guide rollers 19.

[0039] The stainless steel guide roller 19 is pressed onto the surface of the coated copper strip, which facilitates the smoothing of the surface tin layer and achieves uniform coating. The cooled stainless steel guide roller 19 quickly absorbs the heat from the copper strip, resulting in a significant cooling effect and improved production efficiency. Loosening the locking nut 12 allows the sliding screw 13 to slide within the strip-shaped sliding hole 11, which facilitates adjusting the distance between the cooling box 5 and the photovoltaic soldering strip tinning machine 2 as needed. The strip-shaped sliding hole 11 is designed to be open at one end, which facilitates the sliding screw 13 to slide out of the strip-shaped sliding hole 11 and facilitates the disassembly of the cooling box 5.
