[0002] Network transformers are mainly used in high-performance digital switches. The network transformer is in the shape of a rectangular block. After the production of the network transformer is completed, it is necessary to tin-plate its pins to reduce the occurrence of pin oxidation. The existing method of tin-plating the pins of the network transformer is mainly to manually insert multiple network transformers on a fixture, and then manually operate the fixture to make the pins of the network transformer contact with the molten tin. After each tin-plating is completed, it is necessary to use an iron shovel to scrape off the oxide layer on the surface of the molten tin to ensure the purity of the molten tin. However, manually operating the fixture to make the pins of the network transformer contact with the molten tin for tin-plating operations not only has a large manual labor intensity, but also the human hand is easily scalded by the molten tin when manually scraping the oxide layer on the surface of the molten tin, there is a certain personal safety risk; on the other hand, due to individual differences, when the human hand controls the contact between the pins of the network transformer and the molten tin, due to poor stability, the consistency of the pins after tin-plating is poor. Therefore, it is necessary to improve it. Summary of the Invention

Detailed implementation manner

[0019] As shown in the Figure 1-4 accompanying

[0020] This network transformer pin tinning device includes a frame 1. The cross-section of the frame 1 is in a "C" shape. A tin storage tank 2 is fixedly installed on the inner bottom surface of the frame 1. The tin storage tank 2 is a rectangular tank. A plurality of heating rods 3 are arranged in the tin storage tank 2. The heating rods 3 are externally connected to a power supply. During use, the heating rods 3 heat the molten tin in the tin storage tank 2.

[0021] A tin scraping mechanism is installed on the frame 1 above the tin storage tank 2. The tin scraping mechanism includes a mounting seat 4, a first cylinder 5 and a second cylinder 6. The mounting seat 4 is fixedly installed on the back of the frame 1. A first cylinder 5 is fixedly installed on the mounting seat 4. A second cylinder 6 is fixedly installed on the piston rod of the first cylinder 5 through a cylinder mounting bracket. During use, the piston rod of the first cylinder 5 can push the second cylinder 6 to move upward.

[0022] A relief groove 7 is formed in the frame 1 corresponding to the second cylinder 6. The relief groove 7 is a rectangular groove. A connecting rod 8 is movably arranged in the relief groove 7. One end of the connecting rod 8 is fixedly connected to the piston rod of the second cylinder 6. The other end of the connecting rod 8 is fixedly installed with a connecting plate 9. During use, when the piston rod of the second cylinder 6 extends or retracts, it can drive the connecting plate 9 to move forward or backward.

[0023] A scraper 10 is fixedly installed obliquely below the connecting plate 9. The scraper 10 corresponds to the tin storage tank 2. The length of the scraper 10 is adapted to the length of the diameter of the tin storage tank 2. The purpose of such a setting is that when the connecting plate 9 moves backward, it can drive the scraper 10 to move synchronously. The scraper 10 scrapes the impurities on the surface of the molten tin in the tin storage tank 2, so that the impurities are concentrated on one side edge of the surface of the molten tin in the tin storage tank 2 to ensure the cleanliness of the surface of the molten tin in other areas of the tin storage tank 2.

[0024] A screw motor 11 is fixedly installed on the top of the frame 1 above the tin scraping mechanism. The transmission screw 22 of the screw motor 11 extends to the inside of the frame 1. A limit head 21 is set at the end of the transmission screw 22. A screw nut 12 is threaded on the transmission screw 22 extending to the inside of the frame 1. A lifting frame is installed on the screw nut 12. The lifting frame includes a main rod 13, a bracket 14 and a hanger 15. The main rod 13 is a long rectangular shape. An assembly hole is set at the center of the main rod 13. The assembly hole is clamped with the screw nut 12. Brackets 14 are fixedly installed at both ends of the main rod 13. The cross-section of the bracket 14 is "L"-shaped. The purpose of such a setting is to make the falling position of the bracket 14 relative to the center position of the tin storage tank 2.

[0025] A positioning seat 16 is arranged on the inner side of each bracket 14. The positioning seat 16 is a rectangular body. A mounting groove 17 is opened on the positioning seat 16. The mounting groove 17 is a rectangular groove. A hanging bracket 15 is clamped between the mounting grooves 17 of the two positioning seats 16. The hanging bracket 15 is a long rectangular body. Hanging rods 18 are respectively arranged at both ends of the hanging bracket 15. When in use, the hanging rods 18 at both ends of the hanging bracket 15 can be clamped with the mounting grooves 17 of the positioning seat 16, so as to facilitate the staff to quickly disassemble and replace the hanging bracket 15.

[0026] A material storage trough 19 is provided on the rack 15. The material storage trough 19 is in a variable diameter shape, and both ends of the material storage trough 19 are respectively set in an opening shape. When in use, the network transformer can be installed in the variable diameter material storage trough 19 through the opening, and it is also convenient for the staff to remove the network transformer 23 from the material storage trough 19 of the rack 15.

[0027] The limiting posts 20 are symmetrically arranged on the main rod 13 of the lifting frame. The limiting posts 20 are movably plug-in connected with the frame 1. When in use, the limiting posts 20 limit the main rod 13 to ensure that the lifting frame can be lifted and lowered on the transmission screw 22.

[0028] When the network transformer pin tinning device is used, firstly, a plurality of network transformers 23 to be tinned are inserted into the storage tank 19 of the rack 15, so that the pins of the network transformer 23 extend to the outside of the storage tank 19, and then the rack 15 with the network transformer 23 installed is placed between the positioning seats 16, so that the hanging rod 18 of the rack 15 and the mounting groove 17 of the positioning seat 16 are matched and clamped, and the staff starts the piston rod of the first cylinder 5 to extend, and the piston rod of the first cylinder 5 pushes the second cylinder 6 to move upward, and the second cylinder 6 moves upward while driving the connecting rod 8, the connecting plate 9 and the scraper 10 to move upward synchronously, and the staff starts again. The second cylinder 6 is moved, and the piston rod of the second cylinder 6 extends to drive the connecting rod 8, the connecting plate 9 and the scraper 10 to move forward. At this time, the scraper 10 slides from one end of the tin storage tank 2 to the other end. The staff controls the piston rod of the first cylinder 5 to reset. At this time, the second cylinder 6, the connecting rod 8, the connecting plate 9 and the scraper 10 move downward at the same time, and the scraper 10 contacts the surface of the tin water. The staff controls the piston rod of the second cylinder 6 to reset. At this time, the connecting rod 8, the connecting plate 9 and the scraper 10 move backward at the same time. The scraper 10 scrapes the impurities on the surface of the tin water to one side of the tin water surface, so that the other side of the tin water surface remains clean, which is convenient for subsequent tinning operations.

[0029] After the surface of the tin water is scraped clean, the staff starts the transmission screw 22 of the screw motor 11 to rotate clockwise. When the transmission screw 22 rotates clockwise, with the cooperation of the transmission screw 22, the screw nut 12 and the limit column 20, the hanging bracket 15 of the lifting frame drives the network transformer 23 to move downward synchronously until the pins of the network transformer 23 contact the tin water. When most of the pins are immersed in the tin water, the transmission screw 22 stops rotating, and the staff starts the transmission screw 22 to rotate counterclockwise, and the hanging bracket 15 of the lifting frame drives the network transformer 23 to move upward synchronously. After the lifting frame is reset, the team members remove the hanging bracket 15 and take out the network transformer 23 with tin-plated pins from the hanging bracket 15, thereby completing the tinning operation of the entire network transformer 23. Repeat the above steps to circulate the tinning operation of the network transformer 23.

[0030] The network transformer pin tinning device can install multiple network transformers 23 through the material storage tank 19 of the hanging rack 15, so that the pins of the network transformer 23 are exposed outside the hanging rack 15, and then the hanging rack 15 is placed between the installation grooves 17 of the two positioning seats 16, so that the hanging rod 18 of the hanging rack 15 is matched with the installation groove 17 of the positioning seat 16, thereby completing the installation of the hanging rack 15 and the network transformer 23, and the transmission screw 22 of the screw motor 11 is controlled to rotate, thereby driving the lifting frame to move downward, so that the pins of the network transformer 23 are in contact with the tin water, so that the pins are tinned, and the lifting frame is reset by the screw single machine, and the impurities on the surface of the tin water are scraped by the scraper 10 of the tin scraping mechanism, so that the next hanging rack 15 filled with network transformers 23 can be replaced. The network transformer pin tinning device effectively reduces the amount of manual labor, improves the work efficiency of tinning the pins of the network transformer 23, and ensures the consistency of tinning the pins.
