Description

Technical Field

[0002] In the photovoltaic industry, there are two main production methods for photovoltaic ribbons on the market, one is electroplating; the other is hot-dip plating. Among them, electroplating has a higher cost and has a relatively small market share in the photovoltaic industry, while the mainstream hot-dip plating has a lower cost and has an absolute advantage in the photovoltaic industry. Among them, there is a core process in the production process of hot-dip plating, which is tin plating. The tin plating process affects important indicators such as the coating thickness, finished product size, and product surface quality of photovoltaic ribbon products;

[0003] Generally, when tinning a soldering strip, in order to ensure uniformity on the soldering strip, the soldering strip is usually passed through a round hole with a convex rib, and the convex rib contacts the surface of the soldering strip and squeezes the solder, so that the solder is more evenly distributed on the soldering strip to achieve uniform distribution of the solder on the soldering strip. Since this method mainly relies on the shape, material and contact pressure of the convex rib with the soldering strip to achieve uniform distribution of the solder, the uniformity of the solder distribution is subject to certain limitations.

[0017] Furthermore, a method for using a tinning device for a circular solder strip is provided, the method comprising the following steps:

[0018] S1: First, the device is fixed on the top of the solder pool through a fixing plate, and then the solder strip is passed through the surface of the lower pressing plate and one end of the solder strip is passed through the opening in the middle of the square block;

[0019] S2: Then, the middle of the hollow disk is connected to the traction device. After the connection is completed, the lower pressure plate is sunk into the solder pool and the traction device is started at the same time;

[0020] S3: The traction device will pull the solder ribbon to move, and the solder ribbon will pass through the solder pool when moving to complete the tinning work.

[0021] The present invention has the following beneficial effects:

[0022] 1. The present invention first connects the air outlet of the air pump with the air inlet pipe. When the external traction device drives the welding strip to move, the high-pressure gas generated by the air pump will be blown into the air inlet cavity and blown to the surface of the right-angle ring. When the gas blows to the surface of the right-angle ring, the long plate on the right-angle ring will first contact with the gas, and then enter the curved tube through the flexible tube. Then, when the gas flows, the long plate on the right-angle ring will drive the right-angle ring to rotate, and the right-angle ring will drive the curved tube to rotate when rotating. Since the flexible tube is flexible, when the gas enters the curved tube through the flexible tube, the gas will be on the curved tube at the moment when it is sprayed from the flexible tube to the curved tube. A large impact is generated in the wire tube. At this time, the flexible tube will drive the curved tube to rotate up and down when ejecting gas. The spring can play a certain rebound effect. Then the gas entering the curved tube will be sprayed from the air outlet pipe to the surface of the welding strip as the curved tube rotates with the right-angle ring. Since the outlet pipe openings on the curved tube are all slanted downward and the curved tube is curved, when the gas is ejected, the ejected gas will form a vortex-shaped air film on the surface of the welding strip. The vortex air film can help to distribute the tin plating liquid on the surface of the welding strip more evenly, thereby improving the tin plating quality of the welding strip, and at the same time avoiding scratches or damage to the welding strip.

[0023] 2. In the present invention, when the flexible tube sprays air, the impact generated will drive the curved tube to rotate back and forth. When the curved tube rotates downward, the curved tube will generate an outward expansion force. When the curved tube expands outward, the curved tube will pull the rotating disk downward through the connecting rod. When the rotating disk moves downward, it will drive the hollow disk to move downward at the bottom of the reinforcing plate. Then, the rotating disk will also rotate with the right-angle ring through the connecting rod. When the rotating disk rotates, the special-shaped groove on the rotating disk will continuously drive the L rod to move forward and backward. When the L rod moves, the L rod will push the rotating shaft to rotate through the pushing plate. Then, when the hollow disk moves downward, the moving hollow disk will drive the hollow ring to move downward through the C-shaped frame and the fixed sleeve. At this time, on the rotating shaft When rotating, the rotating shaft will drive the push plate to rotate, and when the push plate rotates, it will drive the C-frame to rotate, and when the C-frame rotates, it will drive multiple inclined plates to rotate inside the hollow ring. When the hollow ring rotates, a rotating airflow will be generated on the surface of the curved tube to collect the gas sprayed from the curved tube. At the same time, the gas sprayed from the curved tube will also carry solder droplets into the hollow ring. At this time, when the hollow disk moves up and down with the reciprocating rotation of the curved tube, the hollow ring will collect the gas carrying the solder into the hollow ring through the rotating inclined plate, which can reduce the solder splashing on the surface of the solder strip when the curved tube is spraying air, and make it difficult for the splashing to escape from the air flow range, thereby effectively preventing the splashing and waste of solder.

[0024] 3. In the present invention, when the rotation of the gear shaft drives the gear ring to rotate, the rotating gear ring will drive the raised plate and the fixed plate to rotate. When the raised plate rotates, the raised plate will periodically squeeze one end of the straight plate. After the straight plate is squeezed, it will drive the square frame to rotate on the limiting plate 2. After the square frame rotates, the side wall of the square frame will fit against the side wall of the inclined plate. Then, when the inclined plate rotates, the square frame fitted against the side wall of the inclined plate will scrape on the side wall of the inclined plate. When the inclined plate rotates, the solder adhered to the inclined plate can be cleaned by scraping, so as to avoid the solder clogging the gap between the two inclined plates due to excessive adhered solder when the inclined plate rotates for a long time, which will affect the rotation of the inclined plate and the collection of solder splashes.

[0025] 4. In the present invention, when the gear shaft drives the gear ring to rotate, the rotation of the gear ring will drive the roller to rotate through the contact between the fixed plate and the roller on the special-shaped rod, and the roller will drive the special-shaped rod to rotate when rotating. When the special-shaped rod rotates, it will rotate in the rectangular groove in the middle of the friction plate, and when the special-shaped rod rotates, it will drive the friction plate through the rectangular groove in the middle of the friction plate to make it reciprocate back and forth inside the square frame. At this time, the moving friction plate will rub the stubborn solder droplets adhered to the inclined plate while the square frame fits against the side wall of the inclined plate. The reciprocating movement of the friction plate can further achieve the effect of removing the solder. The friction force generated when the friction plate slides can more effectively peel off the solder adhered to the inclined plate, especially those stubborn solder particles that are difficult to remove by simple friction, and at the same time enhance the cleaning effect of scraping the square frame, thereby improving the overall reliability of the equipment.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] A method for using a tinning device for a circular solder strip, the method comprising the following steps:

[0054] S1: First, the device is fixed on the top of the solder pool by the fixing plate 101, and then the solder strip is passed through the surface of the lower pressing plate 204 and one end of the solder strip is passed through the opening in the middle of the square block 201;

[0055] S2: Then, the middle of the hollow disk 401 is passed through to connect with the traction device. After the connection is completed, the lower pressing plate 204 is sunk into the solder pool and the traction device is started at the same time;

[0056] S3: The traction device will pull the solder ribbon to move, and the solder ribbon will pass through the solder pool when moving to complete the tinning work.

[0057] When in use, first, this device is fixed on the top of the solder pool through the fixing plate 101, and then the solder strip is passed through the surface of the lower pressure plate 204 to pass one end of the solder strip through the opening in the middle of the square block 201, and then passed through the middle of the hollow disk 401 to connect with the traction device. After the connection, the lower pressure plate 204 is placed in the solder pool, and the traction device is started at the same time.

Then, when the gas flows, the long plate on the right-angle ring 301 will drive the right-angle ring 301 to rotate, and when the right-angle ring 301 rotates, it will drive the curved tube 302 to rotate. Since the flexible tube 303 is flexible, when the gas enters the curved tube 302 through the flexible tube 303, the gas is sprayed from the flexible tube 303 to the curved tube 302. At that moment, a greater impact will be generated in the curved tube 302. At this time, the flexible tube 303 will drive the curved tube 302 to rotate up and down when ejecting gas, and the spring 304 can play a certain rebound effect. Then, the gas entering the curved tube 302 will be ejected from the air outlet pipe to the surface of the welding strip as the curved tube 302 rotates with the right-angle ring 301. Since the outlet pipe openings on the curved tube 302 are all slanted downward and the curved tube 302 is curved, when the gas is ejected, the ejected gas will form a vortex-shaped air film on the surface of the welding strip. The vortex air film can help to make the tin plating liquid on the surface of the welding strip more evenly distributed, thereby improving the tin plating quality of the welding strip, and at the same time avoiding scratches or damage to the welding strip.When the flexible tube 303 sprays air, the impact generated will drive the curved tube 302 to rotate back and forth. When the curved tube 302 rotates downward, the curved tube 302 will generate an outward expansion force. When the curved tube 302 expands outward, the curved tube 302 will pull the rotating disk 306 downward through the connecting rod 305. When the rotating disk 306 moves downward, it will drive the hollow disk 401 to move downward at the bottom of the reinforcing plate 205. Then, the rotating disk 306 will also rotate with the rotation of the right-angle ring 301 through the connecting rod 305. When the rotating disk 306 rotates, the special-shaped groove on the rotating disk 306 will continuously drive the L rod 501 to move forward and backward. When the L rod 501 moves, the L rod 501 will push the rotating shaft 505 to rotate through the pushing plate 502. Then, when the hollow disk 401 moves downward, the moving hollow disk 401 will drive the hollow ring 601 to move downward through the C-shaped frame 503 and the fixed sleeve 504. At this time, when the rotating shaft 505 rotates, the rotating rotating shaft 505 will drive the pushing plate 502 to rotate, and when the pushing plate 502 rotates, it will drive the C-frame 503 to rotate. When the C-frame 503 rotates, it will drive multiple inclined plates 606 to rotate inside the hollow ring 601. When the hollow ring 601 rotates, a rotating airflow will be generated on the surface of the curved tube 302 to collect the gas ejected from the curved tube 302. At the same time, the gas ejected from the curved tube 302 will also carry the solder droplets into the hollow ring 601. At this time, when the hollow disk 401 moves up and down with the reciprocating rotation of the curved tube 302, the hollow ring 601 will collect the gas carrying the solder into the hollow ring 601 through the rotating inclined plate 606, which can reduce the solder splashing on the surface of the solder strip when the curved tube 302 is ejected, and make it difficult for the splashing to escape from the air flow range, thereby effectively preventing the splashing and waste of the solder. When the rotation of the gear shaft 602 drives the gear ring 603 to rotate, the rotating gear ring 603 drives the raised plate 605 and the fixed plate 604 to rotate. When the raised plate 605 rotates, the raised plate 605 periodically squeezes one end of the straight plate 704. After the straight plate 704 is squeezed, it drives the square frame 703 to rotate on the second limiting plate 702. After the square frame 703 rotates, the side wall of the square frame 703 is attached to the side wall of the inclined plate 606. Then, when the inclined plate 606 rotates, the square frame 703 attached to the side wall of the inclined plate 606 will play a scraping role on the side wall of the inclined plate 606. When the inclined plate 606 rotates, the solder adhered to the inclined plate 606 can be cleaned by scraping, so as to avoid the solder clogging the gap between the two inclined plates 606 due to excessive adherence when the inclined plate 606 rotates for a long time, which will affect the rotation of the inclined plate 606 and the collection of solder splashes.When the gear shaft 602 drives the gear ring 603 to rotate, the rotation of the gear ring 603 will drive the roller to rotate through the contact between the fixed plate 604 and the roller on the special-shaped rod 705, and the roller will drive the special-shaped rod 705 to rotate when the roller rotates. When the special-shaped rod 705 rotates, it will rotate in the rectangular groove in the middle of the friction plate 706, and when the special-shaped rod 705 rotates, the friction plate 706 will be driven through the rectangular groove in the middle of the friction plate 706, so that it can reciprocate back and forth inside the square frame 703. At this time, the moving friction plate 706 will rub the stubborn solder droplets adhered to the inclined plate 606 while the square frame 703 fits against the side wall of the inclined plate 606. The reciprocating movement of the friction plate 706 can further achieve the effect of removing the solder. The friction force generated when the friction plate 706 slides can more effectively peel off the solder adhered to the inclined plate 606, especially those stubborn solder particles that are difficult to remove by simple friction, and at the same time enhance the cleaning effect of the scraping of the square frame 703, thereby improving the overall reliability of the equipment.
