Technical Field

[0001] The invention relates to the technical field of photovoltaic welding strip production, and in particular to an air cooling mechanism for cooling copper wires of photovoltaic welding strips in separate lanes. Background Art

[0002] Photovoltaic welding ribbon is an important component of photovoltaic modules. It is mainly composed of copper substrate and surface coating. It is used to convert light energy into electrical energy on silicon wafers and transmit it to electrical equipment. The production of photovoltaic welding ribbon can be divided into multiple processes. Each process has its specific function and quality control requirements. The main processes include: material preparation, cleaning, tinning, rough hot pressing, stretching quenching, annealing, quality inspection, surface anti-oxidation treatment, packaging and storage.

[0003] The main material of photovoltaic welding ribbon is copper. Copper is a material that expands when heated and contracts when cooled. At high temperatures, the copper wire will expand; after cooling, the copper wire will shrink to its original size. Therefore, in the above production process of photovoltaic welding ribbon, the temperature of the copper wire of the photovoltaic welding ribbon needs to be strictly controlled, especially in the annealing and tinning processes. Too high or too low temperature will affect the performance of the welding ribbon.

[0004] After searching the prior art, it was found that "a copper wire multi-pass step-by-step drawing production line" has a publication number of "CN112246895B". This device winds the copper wire around the first and second transmission wheels and places it in the drawing die, ensuring that each drawing die can draw normally at the same time without interfering with each other, so as to ensure that each drawing pass can proceed smoothly. This device is equipped with a fan to cool the copper wire being drawn, but the moisture in the air comes into contact with the metal surface, and condensation droplets will be produced on the metal surface after cooling, affecting the quality of the metal. Summary of the invention

[0005] Based on this, it is necessary to provide an air cooling mechanism for cooling the copper wire of photovoltaic welding ribbon in sections to address the problem that moisture in the air comes into contact with the metal surface, condensation droplets will be generated on the metal surface after cooling, and this will affect the copper wire of photovoltaic welding ribbon.

The specific temperature value is appropriately adjusted according to the actual situation. The copper wire inside the cooling middle tube 321 is led into the groove wheel 333. At this time, since the groove wheel 333 is installed on the inner side of the gas bin 332, and the gas is introduced into the gas bin 332 through the high-temperature outlet pipe 334, the photovoltaic welding belt copper wire passes through the high-temperature outlet pipe 334 after the cooling. The airflow passes through the gas bin 332 The groove of the guide groove wheel 333 makes the temperature of the photovoltaic welding strip copper wire closer to room temperature, ensuring good metal properties; the sponge cone sleeve 336 can assist in wiping and adsorbing the cooling liquid droplets on the surface of the photovoltaic welding strip copper wire, reduce the residual liquid on the surface of the photovoltaic welding strip copper wire, and reduce the corrosion of metal materials; the high-temperature air outlet pipe 334 introduces the gas into the gas chamber 332, and the gas is blown to the guide plate 338. Under the guidance of the two groups of staggered guide plates 338, the airflow can be converged to the photovoltaic welding strip copper wire, ensuring the blowing effect on the surface of the photovoltaic welding strip copper wire.

[0026] Working principle: The gas is introduced into the vortex tube 200 through the high-pressure air inlet pipe, and part of the gas is introduced into the low-temperature outlet pipe 312 through the cold air end of the vortex tube 200. The cold air inside the low-temperature outlet pipe 312 is introduced into the spiral tube 313. The temperature of the inlet duct 311 is reduced through the spiral tube 313. The inlet duct 311 quickly condenses the moisture carried by the gas to be introduced, and the external gas is introduced into the low-temperature component 320 through the inlet duct 311 to cool the copper wire of the photovoltaic welding strip. The middle low-temperature tube 317 is set. The middle low-temperature tube 317 is located in the inlet duct 311. The central axis of the inlet duct 311 is provided with a middle low-temperature pipe 317 to improve the condensation effect of the gas inside the inlet duct 311, and the low-temperature gas is guided to the cooling middle pipe 321 through the low-temperature outlet pipe 318; the spiral heat conduction plate 315 is set in a spiral shape, and when the gas enters the inlet duct 311, it fully contacts the surface of the spiral heat conduction plate 315, and the fixed sleeve 314 conducts the low temperature of the spiral tube 313 to the spiral heat conduction plate 315, and the overall temperature of the spiral heat conduction plate 315 is kept balanced through the middle low-temperature pipe 317; the low-temperature liquid tank 100 The cooling middle pipe 321 is located inside the cryogenic liquid tank 100 to keep the cooling middle pipe 321 at a low temperature, and the auxiliary dehumidification component 310 produces a good air cooling effect on the photovoltaic welding strip copper wire. The thermal conductive connector 322 cooperates with the cryogenic liquid tank 100 to enhance the positioning effect of the cooling middle pipe 321 and assist in positioning the cryogenic sleeve 323. The thermal conductive connector 322 conducts the low temperature on the surface of the cryogenic sleeve 323 to the cooling middle pipe 321. The cooling middle pipe 321 maintains a relatively low temperature, and the air inlet 311 and the cooling middle pipe 321 are connected. The tube 321 is connected to the air inlet 311 to introduce the cooling gas into the cooling middle tube 321; the gas is introduced into the cooling middle tube 321 through the air inlet 311, and the gas is discharged to both ends of the cooling middle tube 321. Since the first colloid spiral plate 326 cooperates with the second colloid spiral plate 327 to increase the gas flow rate, the first colloid spiral plate 326 is spirally set to extend the contact path between the gas and the photovoltaic welding strip copper wire, and the low-temperature sleeve 323 guides the low-temperature gas to the cooling coil 324, assisting the dehumidification component 310 to air-cool the photovoltaic welding strip copper wire.
