Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to an inductor coil terminal welding device. Background Technology

[0002] An inductor is a device that works on the principle of electromagnetic induction. A terminal is a wiring end used in electrical connections to transmit electrical signals or conduct electricity. By soldering the terminal to the inductor, the inductor can be made capable of transmitting electrical signals and conducting electricity. When soldering the inductor terminal, the terminal is connected to the inductor terminal by stacking and soldering the end of the inductor.

[0003] Currently, when soldering inductor coils to terminals, it is necessary to press and fix the terminals using a pressure plate before soldering. During the soldering process, the pressure plate, terminals, and soldering heads often come into too close contact, causing the terminals to partially adhere to the pressure plate after soldering and making separation difficult. After soldering, the terminals need to be manually separated from the pressure plate, which reduces the soldering efficiency when soldering a large number of units. Therefore, to address this problem, this application provides an inductor coil terminal soldering device to meet the requirements. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an inductor coil terminal welding device, which fixes the inductor coil by means of a fixed separation component and ensures that the terminal can be separated from the pressure plate after welding, thereby saving the manual separation step and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An inductor coil terminal welding device includes a welding device, a welding head slidably connected to one side of the welding device, a welding table disposed inside the welding device, a lifting platform slidably connected inside the welding device, the lifting platform slidably connected to both sides of the welding head, two fixed pressure plates symmetrically disposed on the top of the lifting platform, the fixed pressure plates being slidably connected to the lifting platform, a first adjusting shaft being threadedly connected inside each of the two fixed pressure plates, the first adjusting shaft being rotatably connected inside the lifting platform, a fixed separation assembly disposed on one side of the lifting platform, a limit assembly disposed on one side of the fixed separation assembly, the fixed separation assembly including a fixing frame slidably connected inside the welding device, two limit side plates symmetrically disposed inside the welding device, the fixing frame being slidably connected to the outside of the two limit side plates, a support plate disposed inside the two limit side plates, the support plate being fixedly connected to the inside of the welding device.

[0006] In the above technical solution, a spring is further fixedly connected to the inner side of the fixing frame, a transmission slide plate is fixedly connected to the bottom end of the spring, a damper is provided on the inner side of the spring, the damper is fixedly connected to the fixing frame, and the damper is in contact with the transmission slide plate.

[0007] In the above technical solution, the bottom of the transmission slide plate is further fixedly connected to a connecting frame, the bottom of the connecting frame is fixedly connected to a transmission base plate, and an arc-shaped side protrusion is fixedly connected to one end of the transmission base plate near the limiting side plate.

[0008] In the above technical solution, further, a limiting frame is fixedly connected to the inner side of the limiting side plate, a movable base frame is slidably connected to the outer side of the limiting frame, a spring piece is fixedly connected to the inner side of the movable base frame, and the spring piece is fixedly connected to the inner side of the limiting side plate.

[0009] In the above technical solution, a lower guide member is fixedly connected to one side of the movable base frame, an upper guide member is fixedly connected to the top of the lower guide member, a transmission pressure plate is fixedly connected to one side of the lifting platform, an arc-shaped limiting member is fixedly connected to one end of the transmission pressure plate, the arc-shaped limiting member is slidably connected to the inner side of the connecting frame, and the arc-shaped limiting member and the upper guide member are arranged in an abutting position.

[0010] The fixed separation component enables the synchronous fixing of the terminals and the inductor coil, thereby improving the stability of the terminals and the inductor coil during welding and ensuring welding quality. At the same time, after welding is completed, the fixing head can be preferentially separated from the terminals, thus avoiding the current situation where the terminals stick to the bottom of the fixing head after welding.

[0011] In the above technical solution, the limiting component further includes a coil limiting frame slidably connected to the inside of the welding device, a third adjusting shaft is threadedly connected to the inside of the coil limiting frame, the third adjusting shaft is rotatably connected to one side of the support plate, a bearing plate is slidably connected to the inside of the coil limiting frame, a fourth adjusting shaft is rotatably connected to one side of the coil limiting frame, and the bearing plate and the fourth adjusting shaft are threadedly connected.

[0012] The limiting component can limit the overlapping area between the inductor coil and the terminal, thereby enabling the welding area between the inductor coil and the terminal to be limited and adjusted, thus ensuring welding quality. At the same time, the height can be adjusted according to the volume of the inductor coil so that inductors of various sizes can be placed on the same horizontal plane, ensuring high adaptability.

[0013] The technical effects and advantages of this invention are as follows: By using a fixed separation component, the inductor coil can be fixed simultaneously with the terminals before welding, ensuring the stability of the terminals and the inductor coil and guaranteeing the welding quality of the inductor coil terminals. After welding, the rising of the fixing head and the fixing of the inductor coil can be carried out sequentially, ensuring that the fixing head can be separated from the terminals first. This avoids the situation where the terminals and fixing head stick together and need to be manually separated, eliminating the step of manually separating the terminals from the fixing head and preventing the fixing head from sticking to the terminals, which would affect welding efficiency. Moreover, the above steps can be repeated to meet the needs of large-scale welding. By setting a limiting component, the inductor coil is placed on the top of the inner support plate of the coil limiting frame during welding, and the inductor coil is ensured to contact the inner side of the coil limiting frame near the support plate. This limits the distance between the inductor coil and the terminal, so that the end of the inductor coil can be located in the limited position of the terminal, preventing the inductor coil from exceeding or lagging behind. This ensures that the welding area between the inductor coil and the terminal is within the required range, thereby unifying the welding area during a large number of welds and ensuring welding quality. The distance between the coil limit frame and the support plate can be controlled by rotating the third adjustment shaft, thereby adjusting the contact area between the inductor coil and the terminal. The lifting and lowering of the carrier plate can be controlled by rotating the fourth adjustment shaft, so that when welding inductors of different sizes, the welding end of the inductor coil can be parallel to the support plate, thus adapting to inductors of different sizes and different welding requirements.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Refer to the instruction manual appendix Figures 1-7 As shown, an embodiment of the present invention provides an inductor coil terminal welding device, comprising a welding device 1, a welding head 2 slidably connected to one side of the welding device 1, a welding table 3 disposed inside the welding device 1, a lifting table 4 slidably connected inside the welding device 1, and an electric push rod disposed inside the welding device 1 to drive the lifting table 4 to rise and fall. The lifting table 4 is slidably connected to both sides of the welding head 2, and two fixed pressure plates 5 are symmetrically arranged on the top of the lifting table 4. The fixed pressure plates 5 are slidably connected to the lifting table 4, and a first adjusting shaft 6 is threadedly connected inside each of the two fixed pressure plates 5. The first adjusting shaft 6 is rotatably connected to the inner side of the lifting table 4. The lifting platform 4 has a fixed separation assembly on one side, and a fixed pressure head 23 is provided at one end of the fixed pressure plate 5. A fixed bolt 24 is fixedly connected to the top of the fixed pressure head 23. The fixed bolt 24 is located inside the fixed pressure plate 5. A second adjusting shaft 25 is rotatably connected to one side of the welding platform 3. Both ends of the second adjusting shaft 25 are provided with threaded grooves, and the two threaded grooves rotate in opposite directions. This allows the two terminal limiting frames 26 to approach or move away from each other when the second adjusting shaft 25 rotates. The terminal limiting frame 26 is threadedly connected to the outside of the second adjusting shaft 25 and is slidably connected to the top of the welding platform 3.

[0018] It should be noted that when soldering the inductor coil terminals, the terminals are placed on the top of the soldering table 3, inside the terminal limiting brackets 26 on both sides. The terminal limiting brackets 26 limit the terminals, keeping them vertical and preventing tilting that could cause the soldering to be tilted. At the same time, by rotating the second adjusting shaft 25, the two terminal limiting brackets 26 can be moved closer or further apart to adjust the distance between them, thus accommodating terminals of different widths.

[0019] After the terminals are placed, the lifting platform 4 is lowered by activating the electric push rod inside the welding device 1. The terminal is then pressed down and fixed by the fixing head 23 at the end of the fixing plate 5. Since the fixing head 23 is fixed to the end of the fixing plate 5 by the fixing bolt 24, the fixing head 23 can be disassembled. In this way, when the top contour of the terminal does not match the fixing head 23 and cannot be fixed, the fixing head 23 can be disassembled and a suitable head can be replaced to adapt to different terminals and ensure that the terminals are firmly fixed.

[0020] At the same time, by rotating the first adjusting shaft 6, the displacement of the fixed pressure plate 5 can be realized so that the fixed pressure head 23 can be in the optimal position on the top of the terminal, ensuring that the terminal is fixed without affecting the welding of the terminal and the inductor coil.

[0021] Furthermore, a limiting component is provided on one side of the fixed separation component. The fixed separation component includes a fixing frame 7 that is slidably connected inside the welding device 1. Two limiting side plates 8 are symmetrically arranged on the inner side of the welding device 1. The fixing frame 7 is slidably connected to the outer side of the two limiting side plates 8. A support plate 9 is provided on the inner side of the two limiting side plates 8. The support plate 9 is fixedly connected to the inner side of the welding device 1. The two limiting side plates 8 and the support plate 9 are combined in a U-shape. A spring 10 is fixedly connected to the inner side of the fixing frame 7. A transmission slide plate 12 is fixedly connected to the bottom end of the spring 10. A damper 11 is provided on the inner side of the spring 10. The damper 11 is fixedly connected to the fixing frame 7. The damper 11 is in contact with the transmission slide plate 12.

[0022] A connecting frame 13 is fixedly connected to the bottom of the transmission slide plate 12. A transmission base plate 14 is fixedly connected to the bottom of the connecting frame 13. An arc-shaped protrusion 15 is fixedly connected to one end of the transmission base plate 14 near the limiting side plate 8. The bottom of the arc-shaped protrusion 15 is arc-shaped. A limiting frame 16 is fixedly connected to the inner side of the limiting side plate 8. A movable base frame 17 is slidably connected to the outer side of the limiting frame 16. A spring piece 18 is fixedly connected to the inner side of the movable base frame 17. The spring piece 18 is an elastic structure. The spring piece 18 is fixedly connected to... Inside the limiting side plate 8, a lower guide 19 is fixedly connected to one side of the movable base frame 17. The top of the lower guide 19 is sloped. An upper guide 20 is fixedly connected to the top of the lower guide 19. The bottom of the upper guide 20 is sloped. A transmission pressure plate 21 is fixedly connected to one side of the lifting platform 4. An arc-shaped limiting member 22 is fixedly connected to one end of the transmission pressure plate 21. The arc-shaped limiting member 22 is slidably connected to the inside of the connecting frame 13. The arc-shaped limiting member 22 and the upper guide 20 are in contact.

[0023] It should be noted that, before the terminal is placed on top of the welding table 3 and fixed, the inductor coil body is placed inside the limiting assembly for limiting, and the welding end of the inductor coil extends above the terminal through the top of the support plate 9. At this time, when the lifting platform 4 is lowered to fix the terminal, the lifting platform 4 will press down on the transmission base plate 14 through the transmission pressure plate 21, causing the transmission base plate 14 to drive the fixing frame 7 to descend. During this period, the spring 10 is not stretched, and since the transmission slide plate 12 and the damper 11 are in contact, the transmission slide plate 12 will not be affected by the force of the damper 11 when it descends. After the damper 11 loses the contact of the transmission slide plate 12, it is gradually stretched under the action of the spring and approaches the transmission slide plate 12. At the same time, the arc-shaped limiting member 22 separates from the upper guide member 20, and the spring piece 18 stretches to push the movable base frame 17 towards the arc-shaped protrusion 15. The distance is less than the distance between the fixed pressure head 23 and the terminal, which causes the fixed frame 7 to contact the inductor coil first. After the fixed frame 7 contacts the inductor coil, it stops descending. At this time, when the transmission base plate 14 continues to descend, the spring 10 will be stretched. At the same time, the force of the spring 10 will increase the downward pressure of the fixed frame 7 on the inductor coil. When the arc-shaped side protrusion 15 contacts the lower guide 19, the arc-shaped side protrusion 15 pushes the movable base 17 to one side through the inclined surface of the lower guide 19, so that the arc-shaped side protrusion 15 passes over the lower guide 19 and is located at the bottom of the lower guide 19. At this time, the lifting platform 4 contacts the terminal and stops descending. The arc-shaped side protrusion 15 is located at the bottom of the lower guide 19 and is limited by the lower guide 19 and cannot rise, thus maintaining the position of fixing the inductor coil. This achieves the fixing of the inductor coil while fixing the terminal, ensuring the stability of the terminal and the inductor coil, and ensuring the welding quality of the inductor coil terminal.

[0024] After welding is completed, the lifting platform 4 is raised by the electric push rod. Since the terminal and the inductor coil are welded together at this time, and the fixed frame 7 is still fixed to the inductor coil when the lifting platform 4 drives the transmission pressure plate 21 to rise, the terminal remains stationary when the fixed pressure head 23 rises. This allows the fixed pressure head 23 to be separated from the terminal, thus avoiding the situation where the terminal and the fixed pressure head 23 are stuck together and need to be manually separated. This achieves the purpose of automatically separating the fixed pressure head 23 from the terminal and avoids the fixed pressure head 23 from sticking together with the terminal, which affects the welding efficiency.

[0025] During the ascent of the lifting platform 4, the transmission pressure plate 21 rises inside the connecting frame 13. When the arc-shaped limiting member 22 contacts the upper guide member 20, the inclined surface of the upper guide member 20 pushes the movable base frame 17 to one side, stopping it on the vertical side of the upper guide member 20, thus keeping the movable base frame 17 in its current position. This causes the lower guide member 19 to separate from the arc-shaped side protrusion 15. At this time, the arc-shaped side protrusion 15 loses its limiting position, and the spring 10 contracts, driving the transmission slide plate 12 to rise. As the transmission slide plate 12 rises, it contacts the damper 11. The damper 11 slows down the rising speed of the transmission slide plate 12, thereby ensuring that the transmission slide plate 12 can return to its original position smoothly. When the spring 10 contracts, it gradually loses its contraction force, thereby reducing the downward pressure of the fixing bracket 7 on the inductor coil and causing the inductor coil to lose its fixation. This allows the rising of the fixing head 23 and the fixing of the inductor coil to occur sequentially after welding is completed, ensuring that the fixing head 23 can be separated from the terminal. This eliminates the need for manual separation of the terminal from the fixing head 23, and the above steps can be repeated to meet the needs of large-scale welding.

[0026] It should be noted that when the transmission pressure plate 21 rises, although the spring 10 can contract to raise the transmission slide plate 12, it cannot raise the fixed frame 7. The raising of the fixed frame 7 needs to be done manually. This step is to release the downward pressure of the fixed frame 7 on the inductor coil.

[0027] Furthermore, the limiting assembly includes a coil limiting frame 27 slidably connected to the inside of the welding device 1, a third adjusting shaft 28 threadedly connected inside the coil limiting frame 27, the third adjusting shaft 28 being rotatably connected to one side of the support plate 9, a bearing plate 29 slidably connected to the inside of the coil limiting frame 27, and a fourth adjusting shaft 30 rotatably connected to one side of the coil limiting frame 27, with the bearing plate 29 and the fourth adjusting shaft 30 being threadedly connected.

[0028] It should be noted that, during welding, the inductor coil is placed on top of the inner support plate 29 of the coil limiting bracket 27, and the inductor coil is ensured to be in contact with the inner side of the coil limiting bracket 27 near the support plate 9. This limits the distance between the inductor coil and the terminal, so that the end of the inductor coil can be located in the limited position of the terminal, preventing the inductor coil from exceeding or lagging behind. This ensures that the welding area between the inductor coil and the terminal is within the required range, thereby unifying the welding area during mass welding and ensuring welding quality.

[0029] The distance between the coil limit frame 27 and the support plate 9 can be controlled by rotating the third adjustment shaft 28, thereby adjusting the contact area between the inductor coil and the terminal. The lifting and lowering of the carrier plate 29 can be controlled by rotating the fourth adjustment shaft 30, so that when welding inductors of different sizes, the welding end of the inductor coil can be parallel to the support plate 9, thus adapting to inductors of different sizes and different welding requirements.
