[0002] Electromagnetic wire, also called enameled wire or insulated wire, is a wire with an insulating film on the surface. Its conductor part is generally annealed undoped pure metal, such as copper, aluminum, etc., and copper alloy, gold, silver, nickel, stainless steel and other materials are also used in some occasions. In order to ensure the length of the electromagnetic wire during use, it is generally necessary to weld the electromagnetic wire to increase its length.

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Example 1

[0050] Reference Figure 1 and Figure 2 , an electromagnetic wire, which is used in the field of electromagnetic wires, and its structure includes a bus core, a filling layer 3, an insulating layer 2 and a corrosion-resistant layer 1 from the inside to the outside.

[0051] Reference Figure 1 and Figure 2 , the bus core is composed of a plurality of cores 4. The cross section of each core 4 is designed to be hexagonal. This shape not only increases the contact area between the cores 4, but also improves the overall structural strength of the electromagnetic wire. In order to ensure that the plurality of cores 4 can be tightly and stably combined together, each core 4 is designed with a groove 5 and a convex strip 6 on two adjacent sides. Specifically, a groove 5 is provided on one side of a core 4, and a convex strip 6 is provided on the corresponding side of another adjacent core 4, so that the groove 5 and the convex strip 6 can be engaged with each other to form a stable connection structure, thereby greatly enhancing the connection stability and overall strength between the plurality of cores 4.

[0052] Reference Figure 1 On the outer wall of the bus core, a filling layer 3 is firstly provided. The material of the filling layer 3 can be selected according to actual needs. In this embodiment, the filling layer 3 can be made of any one of polypropylene, silica gel, polyurethane foam or glass fiber. These materials have good filling performance and certain elasticity, can effectively fill the gaps between the wire cores 4, and further improve the overall stability and durability of the electromagnetic wire.

[0053] Reference Figure 1 , an insulating layer 2 is provided on the outside of the filling layer 3. The main function of the insulating layer 2 is to provide electrical insulation to prevent current leakage or short circuit. In this embodiment, the insulating layer 2 can be made of either polyethylene or cross-linked polyethylene. Both materials have good insulation properties and mechanical strength, and can meet the use requirements of electromagnetic wires in various environments.

[0054] Reference Figure 1 The outermost layer is a corrosion-resistant layer 1, which is mainly made of resin. The resin material has excellent corrosion resistance and can effectively resist the erosion of various corrosive substances, thereby extending the service life of the electromagnetic wire.

[0055] By adopting the above structural design and material selection, the electromagnetic wire provided by this embodiment not only has excellent electrical performance and mechanical strength, but also has good corrosion resistance and stability. This electromagnetic wire can be widely used in various electrical equipment, electronic equipment, communication equipment and other fields to meet the use requirements in various complex environments.

[0056] Reference Figure 3 and Figure 4 , a welding device, which is used in the field of electromagnetic wires, is used to weld the above-mentioned electromagnetic wires. The main body of the device includes a workbench 7, and two movable seats 8 are slidably connected to the top of the workbench 7. The tops of the two movable seats 8 are provided with arc grooves, and these arc grooves are used to place the electromagnetic wires to be welded. A fixed block 28 is fixed on the top of the workbench 7 and located between the two movable seats 8. Two half coils 33 are provided above the fixed block 28. The two half coils 33 can cooperate to form an induction coil for welding the electromagnetic wires.

[0057] Reference Figure 3 , Figure 4 and Fig. 9 A fixing bar 26 is fixed to the top of the fixing block 28 through a support frame, and two racks 27 are fixed to one side of the fixing bar 26. Two vertical plates 16 are also fixed to the top of the workbench 7, and the two vertical plates 16 are respectively located on both sides of the moving seat 8. Two trapezoidal plates 17 are fixed to the side of each vertical plate 16 close to each other.

[0058] Reference Figure 3 and Figure 4 In order to position the multiple cores 4 in the electromagnetic wire, a ring 19 is provided on each side of the two movable seats 8 close to each other.

[0059] Reference Figure 4-Figure 6The device also includes a clamping structure, which is arranged on the top of the movable seat 8 and is used to clamp and fix the electromagnetic wire. The clamping structure specifically includes a plurality of guide rods 9 detachably connected to both sides of the top of the movable seat 8. The outer walls of the plurality of guide rods 9 located on the same side are slidably sleeved with the same first pressing plate 10. The outer wall of each guide rod 9 is sleeved with a first tension spring 11, the top end of the first tension spring 11 is fixedly connected to the outer wall of the adjacent guide rod 9, and the bottom end of the first tension spring 11 is fixedly connected to the top of the adjacent first pressing plate 10. A plurality of cross bars 12 are slidably penetrated in the two first pressing plates 10, and the cooperation of these cross bars 12 and the two first pressing plates 10 can connect the two first pressing plates 10 into a whole. A connecting plate 13 is fixed at one end of the cross bar 12 to facilitate the installation and removal of the cross bar 12. The two first pressing plates 10 are detachably connected to a connecting arm 14 on the side away from each other, and these connecting arms 14 are slidably connected to the movable seat 8. A pin rod 15 is fixed to the bottom of the two connecting arms 14 on the side away from each other. These pin rods 15 cooperate with the adjacent trapezoidal plates 17 to drive the connecting arms 14, the first pressing plate 10 and the cross bar 12 to move downward to clamp the electromagnetic wire.

[0060] When in use, place the electromagnetic wire from above into the arc groove at the top of the moving seat 8, then insert the cross bar 12 into the two first pressure plates 10, and connect the two first pressure plates 10 into a whole. The bidirectional lead screw 43 is driven by the motor to rotate, and the bidirectional lead screw 43 will drive the two moving seats 8 to move toward the middle. During the movement, the pin rod 15 cooperates with the inclined surface of the trapezoidal plate 17, and drives the corresponding first pressure plate 10 and cross bar 12 to move downward through the connecting arm 14. As the moving seat 8 moves, the connecting arm 14 will drive the first pressure plate 10 and cross bar 12 to move downward, squeeze and fix the electromagnetic wire on the moving seat 8, and avoid shaking of the electromagnetic wire during later welding.

[0061] Reference Figure 4-Figure 7The device also includes a positioning structure, which is arranged in the ring 19 and is used to position the multiple cores 4 in the electromagnetic wire to facilitate the subsequent docking of the electromagnetic wire. The positioning structure specifically includes a fixed plate 18 fixed on one side of the ring 19, and the fixed plate 18 is fixed on the side of the movable seat 8 close to the fixed block 28. The inner thread of the ring 19 is penetrated by multiple screws 20, and the ends of these screws 20 close to each other are rotatably connected to a trapezoidal clamping block 21. The cooperation of multiple trapezoidal clamping blocks 21 is used to position multiple spliced ​​cores 4. Multiple sliding rods 22 are fixed on one side of each trapezoidal clamping block 21, and one end of these sliding rods 22 slides through the ring 19 to make the trapezoidal clamping block 21 move smoothly. The outer wall of each screw 20 is slidably connected to a bevel gear 23 through a slide groove and a slider, and these bevel gears 23 rotate on the outer wall of the ring 19. The outer wall of the ring 19 is rotatably sleeved with a bevel gear ring 24, which meshes with the bevel gear 23 to synchronously drive the multiple screws 20 to rotate. A spur gear 25 is fixed to the bottom end of the lowest screw 20, which meshes with the rack 27 to drive the screw 20 to rotate.

[0062] When in use, the bidirectional lead screw 43 is driven by the motor to rotate, and the bidirectional lead screw 43 drives the two moving seats 8 to move toward the middle. During the movement, the spur gear 25 cooperates with the rack 27 to drive the screw 20 and the bevel gear 23 to rotate. With the cooperation of the bevel gear 23 and the bevel gear ring 24, multiple screws 20 will rotate at the same time, pushing the trapezoidal clamping block 21 to move toward the middle. In this way, the trapezoidal clamping block 21 can be just inserted into the gap between two adjacent wire cores 4. The cooperation of multiple trapezoidal clamping blocks 21 can align the position of the electromagnetic wire, which is convenient for accurate welding in the later stage.

[0063] Reference Figure 8 and Fig. 9 Finally, the device also includes a welding structure, which is arranged on the top of the fixed block 28 and is used to splice the two half coils 33 into an induction coil and weld the connected electromagnetic wires. The welding structure includes a guide rod 30 fixedly installed on the top of the fixed block 28. The outer wall of the guide rod 30 is designed as a sliding sleeve with two clamping plates 31, and the two clamping plates 31 can slide freely on the guide rod 30. On the side where the two clamping plates 31 are close to each other, an arc plate 32 is fixedly installed. The design purpose of these two arc plates 32 is to match the half coils 33. When the two arc plates 32 are close to each other, the half coils 33 fixed by them will be spliced ​​together to form a complete induction coil.

[0064] Reference Figure 8 and Fig. 9On the side where the two clamps 31 are away from each other, we have fixedly installed a trapezoidal block 36, and the two trapezoidal blocks 36 can slide freely on the top of the workbench 7. On both sides where the fixed block 28 is away from each other, we have fixedly installed a sliding rod 34, one end of which will slide and extend into the corresponding trapezoidal block 36 to limit the moving direction of the trapezoidal block 36. At the same time, between the two trapezoidal blocks 36 and the fixed block 28, we have fixedly installed a spring 35, which is sleeved on the outer wall of the sliding rod 34 to provide the elastic force required for the trapezoidal block 36 to reset.

[0065] Reference Figure 8 and Fig. 9 , above the two trapezoidal blocks 36, we have a block pressing plate 37, and the two block pressing plates 37 are slidably connected to the bottom of the two adjacent connecting arms 14. When the connecting arm 14 moves downward, it pushes the block pressing plate 37 downward, and the block pressing plate 37 cooperates with the trapezoidal block 36 to push the clamping plate 31 and the arc plate 32 toward the middle, at which time the two half coils 33 just dock to form a complete induction coil.

[0066] In actual operation, when it is necessary to butt-weld the electromagnetic wire, we first place the electromagnetic wire in the circular ring 19 and adjust its position so that it cooperates with the bevel gear ring 24. Then, we start the bidirectional lead screw 43 to drive the two movable seats 8 to move toward each other. As the movable seat 8 moves, the connecting arm 14 will move downward and push the pressure block plate 37 downward. The pressure block plate 37 will then cooperate with the trapezoidal block 36 to push the clamping plate 31 and the arc plate 32 toward the middle, so that the two half coils 33 are butt-jointed to form an induction coil. At this point, we energize the induction coil and can weld the multiple wire cores 4 that are butt-jointed. After the welding is completed, we turn off the power supply, loosen the bidirectional lead screw 43, and take out the welded electromagnetic wire.

[0067] Reference Figure 3 On the top of the workbench 7, we have a fixed rod 42 fixedly installed through the base, and the two moving seats 8 slide on the outer wall of the fixed rod 42. At the same time, on the top of the workbench 7, we also have a bidirectional lead screw 43 rotatably connected through the base, and the bidirectional lead screw 43 is threadedly connected to the two moving seats 8, and the two moving seats 8 are respectively located on the positive and negative thread segments of the bidirectional lead screw 43. When the bidirectional lead screw 43 rotates, it drives the two moving seats 8 to move toward each other.

[0068] Reference Figure 7 We notice that a notch 29 is designed at the top of the circular ring 19 and the bevel gear ring 24. The notch 29 is designed to facilitate the removal of the electromagnetic wire from the circular ring 19, thereby improving the practicability of the device.

[0069] It can be seen from the above description that the electromagnetic wire butt welding device of this embodiment has the advantages of compact structure, simple operation, accurate positioning, good welding effect, etc., and can effectively improve the welding quality and production efficiency of the electromagnetic wire.

[0070] Example 2

[0071] refer to Fig.10 , based on the improvement of embodiment 1: both sides of the top of the moving seat 8 are designed with a detachable structure for installing multiple inclined rods 39. These inclined rods 39 are evenly distributed on the same side, and their outer walls are designed with a sliding sleeve structure, so that the same second pressing plate 41 can slide along the outer walls of these inclined rods 39. This design enables the second pressing plate 41 to achieve oblique movement under the guidance of the inclined rods 39.

[0072] In order to provide the necessary elastic restoring force, the outer walls of the plurality of inclined rods 39 are sleeved with second tension springs 40. The top ends of the second tension springs 40 are connected to the outer walls of the inclined rods 39 by a fixed connection, and their bottom ends are also connected to the tops of the adjacent second pressing plates 41 by a fixed connection. In this way, when the second pressing plates 41 are moved by an external force, the second tension springs 40 can provide corresponding tension to help the second pressing plates 41 return to their initial positions.

[0073] The two second pressing plates 41 are both designed with a detachable connection structure on the side away from each other, which is used to connect the pins 38. These pins 38 serve as connection points, so that the connecting arms 14 can be detachably slidably sleeved on their outer walls. This design allows the connecting arms 14 to move up and down under the guidance of the pins 38, thereby driving the second pressing plates 41 to move accordingly.

[0074] When the pin 15 cooperates with the trapezoidal plate 17 and drives the connecting arm 14 to move downward, the connecting arm 14 transmits force through the pin 38, so that the second pressing plate 41 also moves downward. Due to the cooperation relationship between the second pressing plate 41 and the inclined rod 39, the second pressing plate 41 moves obliquely downward along the inclined rod 39. In this way, the two second pressing plates 41 will clamp the electromagnetic wire under the cooperation of the moving seat 8.

[0075] With this design, the butt welding operation of the electromagnetic wire becomes simpler. When the electromagnetic wire needs to be clamped, the connection arm 14 can be driven downward by the cooperation of the pin rod 15 and the trapezoidal plate 17, thereby driving the second pressing plate 41 to move obliquely. This operation method is not only simple and easy, but also can effectively ensure the stability and welding quality of the electromagnetic wire.

[0076] The structural design and operation steps in the above implementation are based on the content of the claims, ensuring the feasibility and operability of the implementation. At the same time, the implementation also retains all structural features and describes the implementation method, steps and expected effects in detail.

[0077] A method for using an electromagnetic wire butt welding device comprises the following steps:

[0078] S1. Cut off the corrosion-resistant layer 1, the insulating layer 2 and the filling layer 3 of the outer layers of the multiple cores 4 in the two electromagnetic wires, and place the electromagnetic wires in the arc groove on the top of the movable seat 8 from above. At this time, the multiple cores 4 extend to the middle and pass through the circular ring 19. Then insert the cross bar 12 into the two first pressing plates 10, and form the two first pressing plates 10 as a whole. The bidirectional lead screw 43 is driven by a motor to rotate. The bidirectional lead screw 43 drives the two movable seats 8 to move toward the middle. During the movement, the spur gear 25 cooperates with the rack 27 to drive the screw 20 and the bevel gear 23 to rotate. In the cooperation of the bevel gear 23 and the bevel gear ring 24, multiple screws 20 rotate at the same time, and the screw 20 pushes the trapezoidal clamp 21 to move to the middle, just enough to insert the trapezoidal clamp 21 into the gap between the two adjacent cores 4. The cooperation of multiple trapezoidal clamps 21 can align the position of the electromagnetic wire, which is convenient for accurate welding in the later stage.

[0079] S2, and when the movable seat 8 moves, the cooperation between the pin rod 15 and the inclined surface of the trapezoidal plate 17 can drive the corresponding first pressing plate 10 and the cross bar 12 to move downward through the connecting arm 14. At this time, the first tension spring 11 is in a stretched state. As the movable seat 8 moves, the connecting arm 14 drives the first pressing plate 10 and the cross bar 12 to move downward to squeeze and fix the electromagnetic wire on the movable seat 8, so as to avoid shaking of the electromagnetic wire during later welding;

[0080] S3. When the multiple cores 4 in the electromagnetic wire and the electromagnetic wire are clamped and fixed, the movable seat 8 continues to move toward the middle. At this time, the spur gear 25 is disengaged from the rack 27, and the pin 15 slides below the right-angled side at the bottom of the trapezoidal plate 17. The multiple cores 4 of the two electromagnetic wires are relatively docked, and the docking position is located in the arc plate 32. When the movable seat 8 moves toward the middle, the connecting arm 14 moves downward and pushes the pressure block plate 37 downward. The pressure block plate 37 cooperates with the trapezoidal block 36 to push the clamping plate 31 and the arc plate 32 toward the middle. At this time, the two half coils 33 are just docked to form an induction coil. When the induction coil is energized, the docked multiple cores 4 can be welded;

[0081] S4. When the induction coil is connected to multiple wire cores 4 for welding, the movable seat 8 continues to move toward the middle, so that the connected multiple wire cores 4 are further melted and welded to ensure the stability of welding. After welding is completed, the movable seat 8 moves outward, and the clamping force of the movable seat 8 and the first pressing plate 10 on the electromagnetic wire is relatively small, so the first pressing plate 10 and the movable seat 8 slide on the outer wall of the electromagnetic wire after welding. When the movable seat 8 is reset, the first pressing plate 10 releases the clamping of the electromagnetic wire, and the bevel gear ring 24 is reset synchronously, and then the welded electromagnetic wire can be pulled upward through the notch 29, and the electromagnetic wire can be easily taken out, and then when the electromagnetic wire is long, the electromagnetic wire can also be taken out;

[0082] S5. In addition, when it is necessary to clamp the electromagnetic wire on the movable seat 8 more conveniently, remove the connecting arm 14, the guide rod 9, the first tension spring 11 and the first pressure plate 10 from the top of the movable seat 8, fix the pin 38 on one side of the second pressure plate 41, and the connecting arm 14 is slidably sleeved on the outer wall of the pin 38, and then the inclined rod 39 is fixed to the top of the movable seat 8. When the pin 15 cooperates with the trapezoidal plate 17 to drive the connecting arm 14 downward, the connecting arm 14 drives the second pressure plate 41 downward through the pin 38, and the second pressure plate 41 moves obliquely downward through the inclined rod 39. The two second pressure plates 41 cooperate with the movable seat 8 to clamp the electromagnetic wire, and the operation is simpler.

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
