Description
Technical Field
[0001] This utility model belongs to the field of transformer coil processing technology, specifically a welding device for the output end of a transformer coil. Background Technology
[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage, current and impedance. It is an indispensable key component in the power system and is commonly used in power generation, transmission and distribution environments.
[0003] A transformer typically consists of an iron core, windings, insulation system, tank, and bushings. The coil is a crucial component of the windings, serving as the electrical element for inputting and outputting electrical energy. It is the core component for voltage transformation and power transmission. Because the contact surface may have microscopic unevenness when the conductor is directly connected to the output terminal, leading to increased contact resistance, the coil needs to be welded during the manufacturing process. Welding forms a molecular-level bond through metal fusion, significantly reducing contact resistance and minimizing heat loss during operation. During the processing and production of transformer coils, solder or flux is applied using a soldering iron or welding machine for spot welding.
[0004] When soldering the coil lead-out end, because the coil is difficult to keep straight after production, the bent end will cause uneven soldering and thus affect the soldering quality.
[0005] Therefore, this utility model provides a welding device for the output end of a transformer coil. Utility Model Content

[0017] 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.
[0018] like Figures 1 to 4As shown in the embodiment of this utility model, a transformer coil output welding device includes a processing table 1; a support table 2 is fixedly connected to the top of the processing table 1; a lifting welding machine 3 is installed on the top of the support table 2; a pair of electric slide rails 4 are fixedly connected to the top of the processing table 1; the electric slide rails 4 are symmetrically arranged on the processing table 1; a first electric slider 5 is slidably connected to the middle of the electric slide rail 4; a first electric push rod 6 is fixedly connected to the top of the first electric slider 5; a positioning clamp 7 is fixedly connected to the output end of the first electric push rod 6; a second electric slider 8 is slidably connected to the middle of the electric slide rail 4; a second electric push rod 9 is fixedly connected to the top of the second electric slider 8; a connecting bracket 10 is fixedly connected to the output end of the second electric push rod 9; a roller 11 is rotatably connected to the middle of the connecting bracket 10; a fixed base 12 is fixedly connected between the pair of first electric sliders 5; a placement block 13 is fixedly connected to the top of the fixed base 12. During operation, when welding is required at the coil output end, the metal wire is first placed on the placement block 13. The first pair of electric push rods 6 control the positioning clamp 7 to move closer to the metal wire and clamp the middle of the metal wire. At the same time, the second pair of electric push rods 9 drive the connecting bracket 10 to move closer to the metal wire and the roller 11 clamps the metal wire. Then, the second electric slider 8 controls the roller 11 to move away from the fixed base 12. During the movement, the roller 11 straightens the metal wire coil, thus straightening the coil output end. At this time, the positioning clamp 7 moves away from the metal wire coil, and the coil output end is coated with flux or solder. Then, the output end is placed on the placement block 13, and the positioning clamp 7 is used again to clamp and fix the coil. The first electric slider 5 moves the coil output end to below the lifting welding machine 3, and welding is performed by the lifting welding machine 3. By first straightening the coil output end with the roller 11, the problem of uneven welding caused by the coil output end being in a bent state during the welding process is reduced, thus improving the welding quality of the coil output end.
[0019] like Figures 1 to 5As shown, a pair of support frames 14 are fixedly connected to the top of the processing table 1; the pair of support frames 14 are symmetrically arranged on the processing table 1; a horizontal plate 15 is provided between the pair of support frames 14; a compressor fan 16 is fixedly connected to the top of the horizontal plate 15; an air supply pipe 17 is fixedly connected to the output end of the compressor fan 16; a nozzle 18 is fixedly connected to the end of the air supply pipe 17; the air supply pipe 17 and the horizontal plate 15 are fixedly connected. During operation, after welding the coil output end by using the cooperation of the roller 11 and the lifting welding machine 3, it is necessary to control the first electric slider 5 to drive the welding... After the coil is completed, it is reset to the starting position and removed. During this process, the newly welded coil absorbs a lot of heat, which remains on the coil and can easily damage the enameled wire. At this time, while the coil is moving and resetting, the compressor fan 16 is turned on, which generates a large amount of compressed air and delivers it to the nozzle 18 through the air pipe 17. Finally, the compressed air is blown out through the nozzle 18 to cool the surface of the coil, reduce the heat accumulation generated by the newly welded coil, improve the protection of the coil, and increase the welding quality.
[0020] like Figure 5 As shown, the support frame 14 has a groove 19 in the middle; the end of the horizontal plate 15 is located inside the groove 19 and is slidably connected to the groove 19; a pair of drive motors 20 are fixedly connected to the side wall of the processing table 1; a lead screw 21 is fixedly connected to the output end of the drive motor 20; the lead screw 21 passes through the end of the horizontal plate 15 and is threadedly connected to the horizontal plate 15. During operation, by controlling the drive motor 20, the lead screw 21 is driven to rotate, thereby allowing the horizontal plate 15 located in the middle of the lead screw 21 to be adjusted up and down. By controlling the height of the horizontal plate 15, the distance between the nozzle 18 and the coil is adjusted, thereby increasing the concentration of air blown out by the nozzle 18 on the coil while reducing the obstruction of the coil movement caused by the horizontal plate 15 being too low, improving the cooling effect on the coil, and increasing adaptability.
[0021] like Figure 4 As shown, a cleaning roller 23 is rotatably connected to the middle of the connecting bracket 10. The cleaning roller 23 is located on the side of the roller 11 near the fixed base 12. During operation, by providing a cleaning roller 23 in the middle of the connecting bracket 10, after the coil output end is straightened by the roller 11, the coil output end is cleaned by the cleaning roller 23, which reduces the dust and impurities remaining at the output end, improves the stability of the welding process, and increases the welding quality of the coil output end.
[0022] like Figure 3As shown, a rubber head 24 is fixedly connected to the side wall of the positioning clamp 7; the rubber head 24 is located on the side wall of a pair of positioning clamps 7 that are close to each other. During operation, by providing the rubber head 24 on the side wall of the positioning clamp 7, the wear on the coil output end is reduced during the process of using the positioning clamp 7 to clamp the coil output end, and the protection effect of the coil output end is improved while ensuring clamping stability.
[0023] like Figure 5 As shown, a fixing block 22 is fixedly connected to the side wall of the support frame 14; the end of the lead screw 21 and the side wall of the fixing block 22 are rotatably connected. During operation, the fixing block 22 increases the connection end of the lead screw 21, improves the stability of the lead screw 21 during operation, and reduces the possibility of the lead screw 21 deflecting or being damaged.
[0024] Working principle: When welding is required at the coil lead-out end, the metal wire is first placed on the placement block 13. A pair of first electric push rods 6 control the positioning clamp 7 to move closer to the metal wire and clamp the middle of the metal wire. At the same time, a pair of second electric push rods 9 drive the connecting bracket 10 to move closer to the metal wire, and the roller 11 clamps the metal wire. Then, the second electric slider 8 is controlled to drive the pair of rollers 11 to move away from the fixed base 12. During the movement, the pair of rollers 11 straighten the metal wire coil, thereby allowing the coil lead-out. The end is straightened, and the positioning clamp 7 is moved away from the metal wire coil. Then, the coil outlet end and flux or solder are applied. The outlet end is then placed on the placement block 13, and the positioning clamp 7 is used again to clamp and fix the coil. The first electric slider 5 moves the coil outlet end to below the lifting welding machine 3, and welding is performed by the lifting welding machine 3. By first straightening the coil outlet end with the roller 11, the problem of uneven welding caused by the coil outlet end being in a bent state during the welding process is reduced, thus improving the welding quality of the coil outlet end.
[0025] After welding the coil output end using the roller 11 and the lifting welding machine 3, the first electric slider 5 needs to be controlled to drive the welded coil back to the starting position and remove it. During this process, the newly welded coil absorbs a lot of heat, which remains on the coil and can easily damage the enameled wire. At this time, during the coil's repositioning process, the compressor fan 16 is turned on to generate a large amount of compressed air, which is then delivered to the nozzle 18 through the air pipe 17 and finally blown out through the nozzle 18 to cool the coil surface, reduce the heat buildup generated by the newly welded coil, improve the protection of the coil, and increase the welding quality.
[0026] By controlling the drive motor 20, the lead screw 21 is rotated, which allows the horizontal plate 15 located in the middle of the lead screw 21 to be adjusted up and down. By controlling the height of the horizontal plate 15, the distance between the nozzle 18 and the coil is adjusted, thereby increasing the concentration of air blown out by the nozzle 18 on the coil, while reducing the obstruction of the coil movement caused by the horizontal plate 15 being too low, improving the cooling effect on the coil, and increasing adaptability.
[0027] By providing a cleaning roller 23 in the middle of the connecting bracket 10, after the coil output end is straightened by the roller 11, the coil output end is cleaned by the cleaning roller 23, which reduces the dust and impurities remaining at the output end, improves the stability of the welding process, and increases the welding quality of the coil output end.
[0028] By providing rubber heads 24 on the side wall of the positioning clamp 7, the wear on the coil output end is reduced during the clamping process of the positioning clamp 7, thus improving the protection effect of the coil output end while ensuring clamping stability.
[0029] By providing a fixing block 22, the connection end of the lead screw 21 is increased, which improves the stability of the lead screw 21 during operation and reduces the possibility of the lead screw 21 becoming misaligned or damaged.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
