Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a transformer copper wire welding device, including a workbench 1; characterized in that: a first sliding groove 11 is formed on the side wall of the workbench 1; a double-headed motor 12 is fixedly connected to the inner side wall of the workbench 1; a first threaded rod 13 is provided on both sides of the output end of the double-headed motor 12; the first threaded rod 13 is rotatably connected to the side wall of the workbench 1; a driving slider 14 is slidably connected to the side wall of the first threaded rod 13; the driving slider 14 is slidably connected to the side wall of the first sliding groove 11; a wrapping block 15 is fixedly connected to the side wall of the driving slider 14; the side walls of the workbench 1 are symmetrical. A first positioning frame 16 and a second positioning frame 17 are fixedly connected; a drive motor 18 is fixedly connected to the side walls of the first positioning frame 16 and the second positioning frame 17; a second threaded rod 19 is provided at the output end of the drive motor 18; the second threaded rod 19 is rotatably connected to the side walls of the first positioning frame 16 and the second positioning frame 17; an upper clamping plate 101 and a lower clamping plate 102 are provided at both ends of the second threaded rod 19; the second threaded rod 19 is slidably connected to the upper clamping plate 101 and the lower clamping plate 102; a welding machine assembly 103 is provided on the side wall of the workbench 1; during operation, the first First, the insulation layer at the welded end of the copper wire is peeled off. Then, the peeled section of the copper wire insulation is pushed back a certain distance and inserted into the middle of the two side wrapping blocks 15 for fixation. Then, the dual-head motor 12 is started to drive the first threaded rod 13 to rotate, thereby driving the two side wrapping blocks 15 to slide together towards the middle through the drive slider 14, until the copper wire insulation layer is peeled off and passes through the gap in the middle of the upper clamping plate 101 and lower clamping plate 102 on both sides. Then, the workers adjust the position of the copper wire insulation layer peeled off on both sides in the middle, and then start the two drive motors 18 to drive the second threaded rod. The rod 19 rotates, causing the upper clamping plate 101 to slide downwards and the lower clamping plate 102 to slide upwards, thereby clamping the copper wire at the edge of the welding point. Then, by controlling the welding machine assembly 103, the copper wire can be welded without the need for manual clamping of the copper wire at the welding point. This design achieves automatic clamping of the copper wire through a mechanical automated conveying and clamping device, eliminating the need for manual clamping and welding. This reduces the stability of the copper wire during welding, thereby reducing the occurrence of incomplete solder joints and solder pad detachment, and improving the quality of welding.

[0027] Furthermore, such as Figure 1 , Figure 4As shown, positioning sliders 2 are symmetrically arranged on the side wall of the workbench 1; a connecting block 21 is fixedly connected to the side wall of the positioning slider 2; an isolation sleeve 22 is fixedly connected to the side wall of the connecting block 21; the isolation sleeve 22 is located in the middle of the two positioning sliders 2 and corresponds to the middle of the wrapping block 15; during operation, when the copper wire is fixed and transported, the copper wire first passes through the isolation sleeve 22 and reaches the welding point. During this process, the copper wire with the insulation layer stripped will pass through the other end of the isolation sleeve 22, while the part without the insulation layer stripped is shielded and isolated by the isolation sleeve 22. During the welding process, a large number of sparks will be generated and will drift outward from the welding point. The isolation sleeve 22 can isolate the sparks and reduce the number of sparks falling on the copper wire without the insulation layer stripped. This design can reduce the phenomenon of a large number of sparks falling on the insulation layer by shielding and isolating the copper wire after the insulation layer has been stripped, thereby protecting the copper wire without the insulation layer stripped, reducing the phenomenon of the insulation layer being burned by sparks falling on the insulation layer, and improving safety protection.

[0028] Furthermore, such as Figure 1 , Figure 4 As shown, the workbench 1 has symmetrically formed second sliding grooves 3 and multiple sets of positioning threaded grooves 31 on its sidewalls; a positioning slider 2 is slidably connected to the sidewall of the second sliding groove 3; a splicing block 32 is fixedly connected to the sidewall of the positioning slider 2; bolts 33 are rotatably connected to the inner sidewalls of the splicing block 32 and the positioning threaded groove 31; the bolts 33 are threadedly connected to the splicing block 32 and the positioning threaded groove 31; during operation, the positioning slider 2 can be slid at the second sliding groove 3 to adjust its position according to the different stripping length of the copper wire insulation layer. At the same time, the bolts 33 are threadedly connected to the splicing block 32 and the positioning threaded groove 31 to fix the moved positioning slider 2. This design, through the set positioning threaded fixing structure, can adjust the position of the guard sleeve according to the different stripping length of the copper wire insulation layer, thereby improving its applicability and flexibility.

[0029] Furthermore, such as Figure 5 As shown, the side wall of the packaging block 15 has a telescopic groove 4; a spring 41 is fixedly connected to the side wall of the telescopic groove 4; a clamping piece 42 is fixedly connected to the end of the spring 41; the clamping piece 42 is slidably connected to the side wall of the telescopic groove 4; during operation, when the copper wire is inserted into the middle of the packaging block 15 and the copper wire is fixed by the packaging block 15, the clamping piece 42 will compress the spring 41, and at the same time the spring 41 will generate a rebound force to the clamping piece 42, so that the clamping pieces 42 on both sides clamp the copper wire in the middle of the packaging block 15. This design can improve the fixing effect of the copper wire by setting the adaptive elastic clamping device when fixing the copper wire, thereby improving the stable conveying effect of the copper wire.

[0030] Furthermore, such as Figure 3 As shown, the first positioning frame 16 and the second positioning frame 17 are both fixedly connected to the side walls of the limiting slide rail 5; the upper clamping plate 101 and the lower clamping plate 102 are both fixedly connected to the side walls of the limiting block 51; the limiting slide rail 5 is slidably connected to the limiting block 51; during operation, as the upper clamping plate 101 and the lower clamping plate 102 slide up and down, the limiting slide rail 5 can indirectly limit and guide the sliding of the limiting block 51, thus providing a limiting and guiding effect on the lifting and lowering of the upper clamping plate 101 and the lower clamping plate 102. This design can improve the stability of the upper and lower clamping plates during clamping movement by limiting and guiding the sliding of the upper and lower clamping plates.

[0031] Furthermore, such as Figure 1 As shown, a storage box 6 is fixedly connected to the side wall of the workbench 1. During operation, the welding personnel can place the welding materials required for welding in the storage box 6 for easy access. This design improves the operational flexibility during welding by making it easier to place and retrieve the welding materials through the storage box.

[0032] Furthermore, such as Figure 3 As shown, trapezoidal protrusions 7 are provided on the side walls of the upper clamping plate 101 and the lower clamping plate 102. During operation, when the upper clamping plate 101 and the lower clamping plate 102 clamp the copper wire, the trapezoidal protrusions 7 can enhance the contact area with the copper wire. This design improves the clamping stability of the copper wire by increasing the contact area with it when clamping the copper wire.

[0033] Working principle: First, the insulation layer at the welded end of the copper wire is peeled off. Then, the peeled section of the copper wire is inserted into the middle of the two side wrapping blocks 15 and fixed thereon. Next, the dual-head motor 12 is started to drive the first threaded rod 13 to rotate, thereby driving the two side wrapping blocks 15 to slide together towards the middle through the drive slider 14, until the copper wire with the peeled insulation layer passes through the gap in the middle of the upper clamping plate 101 and the lower clamping plate 102 on both sides. Then, the operator adjusts the position of the copper wire with the peeled insulation layer on both sides in the middle, and then starts the two drive motors 18 to drive the second threaded rod 19 to advance. The rotating mechanism causes the upper clamping plate 101 to slide downwards and the lower clamping plate 102 to slide upwards, thereby clamping the copper wires at the edge of the welding area. The copper wires can then be welded by controlling the welding machine assembly 103, eliminating the need for manual clamping. During the transport of the copper wires, they first pass through the isolation sleeve 22 before reaching the welding area. During this process, the copper wires with stripped insulation will pass through the other end of the isolation sleeve 22, while the portion without stripped insulation is shielded and isolated by the isolation sleeve 22. A large number of sparks are generated during the welding process. Sparks disperse outwards from the weld joint. The isolation sleeve 22 isolates the sparks, reducing their impact on the copper wires without stripped insulation. Depending on the stripped insulation length, the positioning slider 2 can be slid at the second groove 3 to adjust its position. Simultaneously, the bolt 33 is threaded into the splicing block 32 and the positioning threaded groove 31 to fix the moved positioning slider 2. When the copper wire is inserted into the center of the wrapping block 15 and fixed by the wrapping block 15, the clamping plate 42 compresses the spring 41. 1. A rebound force is generated on the clamping plate 42, so that the clamping plates 42 on both sides clamp the copper wire in the middle of the wrapping block 15. During the up and down sliding of the upper clamping plate 101 and the lower clamping plate 102, the sliding restriction and guidance of the limiting block 51 by the limiting slide rail 5 can indirectly provide a limiting and guiding effect on the lifting and lowering sliding of the upper clamping plate 101 and the lower clamping plate 102. The welding personnel can place the solder required for welding in the storage box 6 for easy access. When the upper clamping plate 101 and the lower clamping plate 102 clamp the copper wire, the trapezoidal protrusion 7 can enhance the contact area with the copper wire.

[0034] 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. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
