Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic welding strip processing, in particular to a wind knife door opening device for cleaning tin ash without stopping the machine. Background Art

[0002] During the production process of photovoltaic solder strips, due to the use of hot-dip tinning + wind blowing process, the tin outlet of the solder strip will be rapidly oxidized by the wind, forming tin ash. If these tin ashes are not cleaned in time, they will continue to accumulate around the tin outlet, eventually affecting the surface quality of the solder strip, such as causing tin nodules, pits, and uneven tin coating defects. To solve this problem, the traditional method is to manually clean the tin ash at regular intervals, but this method has high operating requirements and limited cleaning opportunities. With the improvement of customer production efficiency, the requirements for axle weight increase. The length of a shaft of solder strip does not increase. When the length is too long, the accumulation of tin ash has seriously affected the product quality before the shaft is changed. This requires manual cleaning of the tin ash in the middle of the process. The probability of defective products is very high, which seriously affects the product quality.

[0003] The prior art has the following defects or problems: The prior art publication number is CN217990125U, which provides an automatic tin ash cleaning device, comprising: a driving motor, a connecting rod, a scraper, a fixed bracket, a cleaning baffle, and an ash-collecting baffle; the front end of the fixed bracket is fixedly connected to the upper end of the wind knife, and the rear end of the fixed bracket is fixedly provided with a cleaning baffle and an ash-collecting baffle; the fixed bracket is provided with a driving motor, the output end of the driving motor is connected to the connecting rod, and the connecting rod is provided with a scraper; the driving motor can drive the scraper to rotate, and when the scraper rotates to one side of the wind knife, it can scrape away the tin ash near the tin-coated copper strip; when the scraper rotates to the other side of the wind knife, the ash-collecting baffle can block the tin ash scraped by the scraper, and then the cleaning baffle can remove the tin ash remaining on the scraper surface. The utility model can realize online continuous cleaning of tin ash, replace manual work, and accurately remove tin ash accumulated in the tin outlet.

[0004] During use, these devices contain multiple precision components, such as drive motors, connecting rods, and scrapers. The installation and maintenance of these components require specialized knowledge, increasing the complexity and maintenance costs of the equipment. Furthermore, the cleaning effectiveness of the device is affected by factors such as the scraper's material, shape, and rotational speed, leading to the risk of incomplete cleaning or damage to the welding ribbon. However, some existing devices make it difficult to quickly remove connected external pipes, increasing maintenance time and costs, and leading to extended production interruptions, impacting production efficiency and output.

[0024] In this embodiment, the air inlet 6 is used to introduce external air, which is mixed with high-pressure nitrogen to form a stronger airflow.

When the automatic valve 7 is opened, external air is introduced and mixed with the high-pressure nitrogen; when the automatic valve 7 is closed, the air entry is stopped to maintain the internal stability of the system. The inner cavity 3 serves as a storage space for gas, ensuring a stable supply of high-pressure nitrogen, and the two gas channels 4 are responsible for guiding the gas mixed with high-pressure nitrogen and air from the inner cavity 3 to the nozzle 5, forming a continuous and stable airflow, so that the mixed gas can be evenly distributed in the entire nozzle 5 area, thereby improving the cleaning effect.

[0026] like Figure 1 - Figure 4As shown, the disassembly component includes an external interface 17, the left side of the external interface 17 is fixedly connected to the right inner wall of the wind knife seat body 1, the interior of the external interface 17 is provided with an inlay groove 2 16, the interior of the inlay groove 2 16 is fixedly connected with a sealing ring 9, the outside of the sealing ring 9 is fixedly connected to the inner wall of the external interface 17, the interior of the external interface 17 is provided with a plurality of accommodating grooves 10, the interiors of the plurality of accommodating grooves 10 are respectively fixedly connected with springs 11, the top of the spring 11 is fixedly connected to the top inner wall of the external interface 17, the bottom end of the spring 11 is fixedly connected to the limiting block 12, the outside of the limiting block 12 is slidably connected to the top inner wall of the external interface 17, the bottom end of the limiting block 12 is fixedly connected with a sliding column 13, the bottom end of the sliding column 13 is in contact with the outside of the fixing ring 15, the interior of the external interface 17 is provided with an inlay groove 14, the interior of the inlay groove 14 is slidably connected with the fixing ring 15, and the outside of the fixing ring 15 is in contact with the inner wall of the external interface 17.

[0027] In this embodiment, when connecting an external pipe, the external pipe is inserted into the interior of the external interface 17, allowing the fixing ring 15 to slide inside the external interface 17. The fixing ring 15, together with the sliding column 13 and the limit block 12, slides inside the external interface 17. The limit block 12 compresses the spring 11, and the elastic deformation of the spring 11 completes the rapid disassembly of the external pipe. The main function of the sealing ring 9 is to ensure the sealing between the external interface 17 and the air knife seat body 1 to prevent gas leakage.

The automatic valve 7 controls the amount of air entering as needed to ensure the stability and continuity of the airflow. When the automatic valve 7 is opened, external air is introduced and mixed with high-pressure nitrogen; when the automatic valve 7 is closed, the air entry is stopped to maintain the internal stability of the system. The inner cavity 3 serves as a storage space for gas, ensuring a stable supply of high-pressure nitrogen, and the two gas channels 4 are responsible for guiding the gas mixed with high-pressure nitrogen and air from the inner cavity 3 to the nozzle 5, forming a continuous and stable airflow, so that the mixed gas can be evenly distributed in the entire nozzle 5 area, ensuring that the high-pressure nitrogen is blown to the tin ash at the best angle and strength, thereby achieving efficient cleaning. When connecting an external pipe, the external pipe is inserted into the interior of the external interface 17, so that the fixing ring 15 slides inside the external interface 17, and the fixing ring 15, with the sliding column 13 and the limit block 12, slides inside the external interface 17. The limit block 12 compresses the spring 11, and the external pipe is quickly disassembled through the elastic deformation of the spring 11. The main function of the sealing ring 9 is to ensure the sealing between the external interface 17 and the wind knife seat body 1 to prevent gas leakage. The sealing ring 9 is made of wear-resistant and high-temperature resistant materials, which can maintain stable performance in harsh working environments, and can complete the rapid disassembly of the external pipe through the elastic deformation of the spring 11, and greatly shorten the maintenance time, reduce the time of production interruption, and thus improve the overall maintenance efficiency.
