Description

Technical Field

[0001] The present application relates to the field of welding devices, and in particular to a welding process for an induction coil. Background Art

[0002] Double-layer inductor coils are widely used not only in heat exchange applications (such as air conditioner evaporators and condensers, and heat exchangers in chemical equipment), but are also gradually being introduced into the field of inductive components. In these applications, welding the terminals to the coil is a critical step in ensuring the reliability of the electrical connection. Especially in applications where electrical connection stability is extremely important, such as industrial control systems and power equipment, welding can provide a secure and low-resistance connection, reducing contact resistance, heat generation, and energy loss, thereby ensuring the normal operation and safety of the equipment.

[0003] The related art discloses a spiral tube welding fixture, which includes a base and a rotating plate located above the base. The rotating plate and the base are connected by a plurality of vertically arranged columns. The bottoms of the columns are fixed to the base. The rotating plate, the base and the plurality of columns are mutually enclosed to form a storage space for placing the spiral tube workpiece. A through hole is opened at a position corresponding to the storage space on the rotating plate. A plurality of arc-shaped slide grooves corresponding to the plurality of columns are opened on the rotating plate. The plurality of arc-shaped slide grooves are evenly distributed along the circumferential direction on the outside of the through hole. The top of each column slides respectively. Connected in the corresponding arc-shaped slide groove, the bottom of the rotating plate is provided with an upper clamping groove along the tangential direction of the through hole for clamping the upper lead-out end of the spiral tube workpiece, the top of the base is located at a position corresponding to the accommodating space and is provided with a positioning hole for positioning the bottom of the spiral tube workpiece, and the top of the base is provided with a lower clamping groove along the tangential direction of the positioning hole for clamping the lower lead-out end of the spiral tube workpiece; a central tightening rod for tightening the spiral tube workpiece is provided in the accommodating space along the vertical movement, the central tightening rod is inserted into the accommodating space through the through hole of the rotating plate, and the bottom of the central tightening rod is inserted into the positioning hole of the base.

[0004] However, when this welding fixture designed for spiral tube workpieces is applied to the welding of inductor coils, there are significant defects and shortcomings. Specifically, the structure of an inductor coil is fundamentally different from that of a spiral tube workpiece. The inductor coil consists of an inner coil and an outer coil, which form a concentric circle structure and are connected by a connecting wire. The free ends of the outer coil and the inner coil are also integrally formed with a bent section for mounting and welding the terminal. This special structure requires the welding fixture to have a highly precise positioning capability to ensure that the terminal can be accurately mounted on the bent section and reliably welded. However, the welding fixtures in the related art are not positioned for this special structure of the inductor coil and lack a precise positioning mechanism for the inner coil, outer coil, and their bent section. This can cause the inductor coil to shake or deviate from its position during the welding process, thereby affecting the welding quality and even leading to welding failure. In addition, due to the extremely high positioning accuracy requirements for inductor coil welding, the fixtures in the related art may be more complicated to operate and less efficient, and cannot meet the production needs of inductor coil welding. Summary of the Invention

[0005] In order to improve the welding efficiency of a double-layer inductor coil, the present application provides a welding process for an inductor coil.

[0006] The present application provides a welding process for an inductor coil using the following technical solution: In a first aspect, the present application discloses a welding process for an inductor coil, comprising the following steps: Step 1: Sleeve the first terminal block onto the first bent section of the inductor coil, and simultaneously sleeve the second terminal block onto the second bent section of the inductor coil; Step 2: Place the inductor coil on the positioning fixture of the positioning mechanism in the idle state in the welding device for positioning, while the inductor coil on the other positioning mechanism is in the welding state; Step 3: Start the welding device and weld the terminal block of the positioned inductor coil to the bent section of the inductor coil. During the welding process, the worker can repeat step 1 on another idle positioning mechanism to set the terminal block of the inductor coil to be welded. Step 4: After the welding of an inductor coil is completed, remove the finished inductor coil from the corresponding positioning fixture, and place the inductor coil to be welded with the terminal blocks installed in step 3 on the positioning fixture, and then repeat steps 1 to 4 to achieve simultaneous welding and replacement of the inductor coil.

[0007] By adopting the above technical solution, the spiral tube welding fixture in the related technology cannot meet the welding requirements of the special structure of the inductor coil, because it lacks a precise positioning mechanism for the inner coil, outer coil and its bending section, which can easily cause the inductor coil to shake or deviate in position during welding, affecting the welding quality or even leading to failure, and the operation is complicated and inefficient. The present application provides a welding process for an inductor coil. By setting two positioning mechanisms, during the welding process, when the inductor coil on one positioning mechanism is in a welding state, the staff can perform the terminal installation operation of the inductor coil to be welded on the other idle positioning mechanism. When the welding of one inductor coil is completed, the finished welded inductor coil is immediately removed and replaced with the inductor coil to be welded with the terminal installed, so that welding and replacement of the inductor coil can be carried out simultaneously, which effectively improves the welding efficiency of the double-layer inductor coil. At the same time, the precise positioning mechanism also ensures the welding quality and meets the production requirements of inductor coil welding.

[0008] Optionally, the inner coil is placed in an annular positioning cavity formed between the inner positioning column and the positioning ring; the outer coil of the inductor coil is sleeved on the positioning ring, and the inner side wall of the outer coil abuts against the inner side wall of the positioning ring, and the ends of the inner coil and the outer coil both abut against the upper surface of the supporting block, and the connecting wire is placed in the positioning cavity.

[0009] By adopting the above technical solution, in terms of structural layout, an annular positioning cavity is formed between the inner positioning column and the positioning ring. The function of this annular positioning cavity is to accommodate and position the inner coil of the inductor coil. The inner coil is placed in this annular positioning cavity to ensure the accuracy and stability of its position. At the same time, the outer coil of the inductor coil is sleeved on the positioning ring. The inner side wall of the outer coil is tightly abutted against the inner side wall of the positioning ring, which not only helps to fix the position of the outer coil, but also ensures the relative position relationship between it and the inner coil, thereby ensuring the overall performance of the inductor coil. In terms of working principle, the ends of the inner coil and the outer coil are both abutted against the upper surface of the supporting block. The supporting block plays a supporting and positioning role here, ensuring that the inductor coil can remain stable when subjected to external forces. In addition, the connecting wires are also placed in the positioning cavity, which helps to organize and protect the connecting wires to prevent them from being damaged or interfered with.

[0010] Optionally, the positions of the inductor coil, the first terminal and the second terminal are adjusted so that the first bent section of the inductor coil is located in the first positioning channel, the second bent section of the inductor coil is located in the second positioning channel, the bottom end of the first terminal abuts against the top end of the terminal positioning column, and the second terminal is located in the terminal positioning groove.

[0011] By adopting the above technical solution, the first bent section of the inductor coil is precisely placed in the first positioning channel to ensure that its position is accurate and stable; at the same time, the second bent section of the inductor coil is placed in the second positioning channel to also ensure the accuracy of its positioning. In this way, both bent sections of the inductor coil are properly positioned, laying the foundation for subsequent electrical connection and stable work. Next, the terminal is positioned. The bottom end of the first terminal is abutted against the top end of the terminal positioning column, and the stability of the first terminal in the device is ensured by the support and positioning function of the terminal positioning column. At the same time, the second terminal is placed in the terminal positioning groove, and the shape and size restrictions of the terminal positioning groove are used to keep the second terminal in the correct position and direction. Precise positioning of the inductor coil and its terminal is achieved.

[0012] Optionally, the specific steps for starting the welding device in step 3 are: S1: The first driving assembly in the positioning mechanism drives the first movable seat to move horizontally, and moves the positioning fixture to the bottom of the support seat so that the inductor coil is in the welding position; S2: The second movable base is driven by the second driving assembly in the welding mechanism to move horizontally to above the positioning mechanism so that the welding assembly is aligned with the part to be welded of the inductor coil; S3: The lifting seat is driven down by the lifting drive assembly, and the welding assembly is driven down to a suitable height, so that the soldering iron of the welding assembly contacts the terminal and the bending section of the inductor coil; S4: Start the welding assembly to perform the welding operation, weld the first terminal to the first bending section, and weld the second terminal to the second bending section at the same time, thereby completing the welding of the inductor coil.

[0013] By adopting the above technical solution, when welding operation is required, the first movable seat is first driven by the first driving component of the positioning mechanism to move the inductor coil on the positioning jig accurately to the bottom of the support seat, that is, the welding position. At this time, the second driving component in the welding mechanism starts to work, driving the second movable seat to move above the positioning mechanism, so that the welding assembly is aligned with the part to be welded of the inductor coil. Then, the lifting drive component drives the lifting seat to descend, driving the welding assembly to a suitable height to ensure that the soldering iron is in full contact with the terminal and bending section of the inductor coil. Finally, the welding assembly is started to perform the welding operation, the first terminal is welded to the first bending section, and the second terminal is welded to the second bending section at the same time, thereby completing the welding of the inductor coil. Accurate positioning and efficient welding of the inductor coil are achieved.

[0014] Optionally, the tin wire on the winding mechanism is guided and steered through two guide wheels in sequence; the third driving component of the wire feeding mechanism drives the first rotating shaft to rotate, driving the first wire feeding wheel to rotate; the adjusting component drives the swing seat to swing around the first mounting rod through the rotation of the eccentric wheel, so that the second rotating shaft drives the second wire feeding wheel to swing, changing the distance between the first wire feeding wheel and the second wire feeding wheel, realizing the clamping and release of the tin wire, and accurately controlling the transmission speed and wire feeding amount of the tin wire; the tin wire is conveyed to the guide tube of the guide assembly with the cooperation of the first wire feeding wheel and the second wire feeding wheel; the guide tube conveys the tin wire to the electric soldering iron, and the electric soldering iron melts the tin wire to complete the welding of the first terminal and the first bending section and the welding of the second terminal and the second bending section.

[0015] By adopting the above technical solution, when soldering is required, the tin wire on the winding mechanism is first guided and steered by two guide wheels, ensuring the accuracy of the wire transmission path. Subsequently, the third drive assembly of the wire feeding mechanism activates, rotating the first rotating shaft, which in turn drives the first wire feeding wheel. Simultaneously, the adjustment assembly adjusts the rotation angle of the eccentric wheel according to the welding requirements, pushing the swing seat to swing about the first mounting rod. This causes the second rotating shaft to swing the second wire feeding wheel, thereby changing the spacing between the first and second wire feeding wheels. This spacing adjustment allows for precise control of the wire's transmission speed and feed rate. With the close cooperation of the first and second wire feeding wheels, the tin wire is stably and accurately fed into the guide tube of the guide assembly. The guide tube further guides the tin wire to the soldering iron. When powered on, the soldering iron generates high temperatures, melting the tin wire and completing the soldering between the first terminal and the first bent section, and the second terminal and the second bent section.

[0016] In the second aspect, the present application discloses a welding device for the above-mentioned welding process, including a machine base, a positioning mechanism, a welding mechanism, a wire winding mechanism, a guide mechanism and a wire feeding mechanism; the machine base includes a base and a support base, and the support base is fixed to the upper surface of the base; the positioning mechanism is arranged on the base, for positioning the inductor coil; the welding mechanism, wire winding mechanism, guide mechanism and wire feeding mechanism are all arranged on the support base, the welding mechanism is used to weld the terminal to the inductor coil, the wire winding mechanism is used to wind the tin wire and transfer the tin wire to the wire feeding mechanism through the guide mechanism, and the wire feeding mechanism is used to transfer the tin wire to the welding mechanism.

[0017] With the above technical solution, the winding mechanism first takes over, winding the tin wire and guiding it to the wire feeding mechanism via the guide mechanism. The guide mechanism plays a crucial role here, ensuring an accurate and smooth path for the tin wire during transport, preventing tangles or deviations. After receiving the tin wire, the wire feeding mechanism precisely controls the wire delivery speed and feed rate through its internal third drive assembly and adjustment assembly. During this process, the wire feeding mechanism can clamp or release the tin wire as needed, ensuring stable and accurate delivery to the soldering mechanism. Simultaneously, the positioning mechanism has precisely positioned the inductor coil in the soldering position. Once the wire feeding mechanism delivers the tin wire to the soldering mechanism, the soldering mechanism begins operation. Using a soldering tool, such as a soldering iron, the tin wire is melted and precisely dripped between the inductor coil's terminal block and the bend section, completing the soldering operation.

[0018] Optionally, the positioning mechanism includes a first movable seat, a first driving assembly and a positioning jig; the first movable seat is slidably cooperated with the base, and the first driving assembly is arranged on the base for driving the first movable seat to move in the horizontal direction; the positioning jig is fixed on the first movable seat for positioning the inductor coil; the positioning jig includes a base plate, a bearing block, an inner positioning column and a positioning ring, the bearing block is fixed to the surface of the base plate, the inner positioning column and the positioning ring are both fixed to the surface of the bearing block, an annular positioning cavity for positioning the inner coil is formed between the inner positioning column and the positioning ring, and a avoidance cavity for accommodating the connecting wire is provided on the positioning ring; the upper surface of the base plate is also fixedly provided with a first positioning seat, a second positioning seat and a terminal positioning seat, the first positioning seat is provided with a first positioning channel, the second positioning seat is provided with a second positioning channel, and the terminal positioning seat is provided with a terminal positioning groove.

[0019] By adopting the above technical solution, when the inductor coil needs to be positioned in the welding position, the first drive assembly is activated, driving the first movable seat to move horizontally, driving the positioning fixture to move together. When the positioning fixture moves to the specified position, the staff places the inductor coil on the positioning fixture and ensures that the inductor coil and the terminal are in the correct welding position through the precise positioning of the annular positioning cavity, the first positioning channel, the second positioning channel, and the terminal positioning groove. At this point, the positioning mechanism has completed its positioning task and is fully prepared for subsequent welding operations. The precise positioning and stable fixation of the inductor coil are achieved, providing reliable protection for the welding operation.

[0020] Optionally, the welding mechanism includes a second movable seat, a second drive assembly, a lifting seat, a lifting drive assembly and a welding assembly; the second movable seat is slidably engaged with the crossbeam, and the second drive assembly is arranged on the crossbeam to drive the second movable seat to move in the horizontal direction; the lifting seat is slidably engaged with the second movable seat, and the lifting drive assembly is arranged on the second movable seat to drive the lifting seat to move up and down; the welding assembly is arranged on the lifting seat, and the welding assembly is used to weld the first terminal to the first bending section, and to weld the second terminal to the second bending section.

[0021] By adopting the above technical solution, first, the second drive assembly is started, driving the second movable seat to move horizontally along the crossbeam, and quickly and accurately positioning the welding assembly above the area to be welded of the inductor coil. During this process, the sliding cooperation between the second movable seat and the crossbeam ensures the smooth movement and the accuracy of positioning. Then, the lifting drive assembly starts to work, driving the lifting seat to descend, and driving the welding assembly to gradually approach the inductor coil. When the welding assembly descends to a suitable height, its welding head is in close contact with the terminal of the inductor coil. At this time, the welding assembly starts to weld the first terminal and the second terminal to the inductor coil. After welding is completed, the lifting drive assembly is started again, driving the lifting seat to rise, and driving the welding assembly to leave the welding position and prepare for the next welding.

[0022] Optionally, the wire feeding mechanism includes a first rotating assembly, a second rotating assembly, a third driving assembly, an adjusting assembly and a linkage assembly; the first rotating assembly includes a first rotating shaft and a first wire feeding wheel, the first rotating shaft passes through the support and is rotatably connected to the support, the first wire feeding wheel is sleeved on the first rotating shaft and fixedly connected to the first rotating shaft; the second rotating assembly includes a second rotating shaft, a second wire feeding wheel and a second linkage gear, one end of the second rotating shaft passes through the bottom end of the swing seat and is rotatably connected to the swing seat, the other end of the second rotating shaft extends out of the support, the second wire feeding wheel is sleeved on one end of the second rotating shaft extending out of the support, and the second linkage gear is sleeved on the second rotating shaft The eccentric wheel is fixedly connected to the first mounting rod and is fixedly connected to the second rotating shaft; the third driving assembly is used to drive the first rotating shaft to rotate; the adjusting assembly includes a first mounting rod, a swing seat, a second mounting rod, an eccentric wheel and a driving rod, both ends of the first mounting rod are passed through the support and are rotatably connected to the support, the swing seat is rotatably connected to the first mounting rod, both ends of the second mounting rod are passed through the support and are fixedly connected to the support. An eccentric hole is opened at the eccentric position of the eccentric wheel, the second mounting rod passes through the eccentric hole of the eccentric wheel, the eccentric wheel is rotatably connected to the second mounting rod, the side wall of the eccentric wheel abuts the side wall of the swing seat, the driving rod is fixedly arranged on the swing seat and one end away from the swing seat extends out of the support.

[0023] By adopting the above technical solution, the wire feeding mechanism includes a first rotating assembly, a second rotating assembly, a third driving assembly, an adjusting assembly, and a linkage assembly. The third driving assembly drives the first rotating shaft to rotate, driving the first wire feeding wheel to rotate, while the adjusting assembly drives the swing seat to swing around the first mounting rod through the rotation of the eccentric wheel, thereby causing the second rotating shaft to drive the second wire feeding wheel to swing, changing the distance between the first wire feeding wheel and the second wire feeding wheel. This enables the wire feeding mechanism to clamp or release the tin wire in a timely manner according to the welding requirements, ensuring that the tin wire can be stably and accurately transmitted to the welding mechanism. This precise control not only improves the accuracy and quality of welding, but also avoids welding defects caused by unstable tin wire transmission, such as incomplete solder joints, cold solder joints, and other problems. At the same time, the automated control of the wire feeding mechanism also reduces the difficulty and error of manual operation, thereby improving production efficiency.

[0024] Optionally, the guide assembly includes a fixed seat and a guide tube, the fixed seat passes through the clamping block and is fixedly connected to the clamping block, the guide tube passes through the fixed seat and is fixedly connected to the fixed seat, both ends of the guide tube are open, and the guide tube is inclined, and the bottom end of the guide tube faces the soldering iron, which is used to accurately transfer the tin wire to the soldering iron.

[0025] By adopting the above-mentioned technical solution, the guide assembly provides a stable and precise guide path for the tin wire as it is transported from the wire feed mechanism to the soldering position. After the tin wire is fed from the wire feed mechanism, it enters the top opening of the guide tube and slides down the inside of the guide tube. Because the guide tube is tilted, gravity naturally accelerates the tin wire's downward movement until it reaches the bottom opening of the guide tube. At this point, with the bottom end of the guide tube facing the soldering iron, the tin wire is accurately delivered to the soldering iron's soldering position, providing the necessary soldering materials for subsequent soldering operations, thereby improving soldering quality and production efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up two positioning mechanisms, the present application realizes the parallel operation of welding and replacing the inductor coil. When the inductor coil on one positioning mechanism is in the welding state, the staff can perform the wiring terminal installation operation of the inductor coil to be welded on the other idle positioning mechanism. When the welding of an inductor coil is completed, the finished welded inductor coil is immediately removed and replaced with the inductor coil to be welded with the wiring terminal installed. This parallel operation method greatly improves the overall welding efficiency, reduces the production cycle, and meets the needs of large-scale production; 2. The positioning mechanism achieves precise positioning of the inductor coil and its terminal blocks through structures such as the annular positioning cavity, the first positioning channel, the second positioning channel, and the terminal positioning slot. This precise positioning mechanism ensures the stability and accuracy of the inductor coil during welding, avoiding welding quality issues caused by inductor coil shaking or position deviation. At the same time, the welding mechanism achieves precise positioning and operation of the welding assembly in three-dimensional space through the coordinated operation of the second drive assembly and the lifting drive assembly, further improving the accuracy and quality of welding. 3. The winding mechanism is responsible for winding the tin wire and guiding it to the wire feed mechanism via a guide mechanism. The wire feed mechanism precisely controls the wire feed speed and quantity via a third drive component and an adjustment component. The welding mechanism automatically adjusts the position and height of the welding components according to welding requirements to execute the welding operation. This automated and intelligent control method not only improves production efficiency and quality, but also reduces the difficulty and error of manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0038] For ease of understanding, in this embodiment, the length direction of the beam 221 is defined as the first direction in the horizontal direction, and the length direction of the first movable seat 31 is defined as the second direction, based on which a welding process of an inductor coil is described.

[0039] Example 1 The embodiment of the present application discloses a welding process for an inductor coil. Figure 1 and Figure 2 , a welding process for an inductor coil comprises the following steps: Step 1: Terminal block installation The staff puts the first terminal 15 on the first bending section 13 of the inductor 1, and puts the second terminal 16 on the second bending section 14 of the inductor 1. This step prepares for subsequent welding and ensures that the terminal can be accurately placed in the position to be welded. Specifically, the inductor 1 includes an inner coil 11 and an outer coil 12 located outside the inner coil 11. The outer coil 12 and the inner coil 11 are formed by bending the same enameled wire. The outer coil 12 and the inner coil 11 form a concentric circle structure, and the outer coil 12 and the inner coil 11 are connected by a connecting wire. The free end of the outer coil 12 is integrally formed with a first bending section 13 after bending, and the free end of the inner coil 11 is integrally formed with a second bending section 14. The first bending section 13 is provided with a first terminal 15, and the second bending section 14 is provided with a second terminal 16.

[0040] Step 2: Positioning the Inductor 1 Reference Figure 3 、 Figure 4 and Figure 5 , place the inductor coil 1 on the positioning jig 33 of the welding device for positioning. Specifically, there are two positioning mechanisms 3 in the welding device, and the two positioning mechanisms 3 are arranged at intervals along the first direction. The staff places the inductor coil 1 on the positioning jig 33 of one of the positioning mechanisms 3. The annular positioning cavity 335 in the positioning jig 33 fits tightly against the inner coil 11 to ensure that the inner coil 11 does not shake during the positioning process. The avoidance cavity 336 on the positioning ring 334 provides a suitable accommodation space for the connecting wire to prevent the connecting wire from being squeezed or interfered with during the positioning process. The first positioning channel 3373 of the first positioning seat 337 is adapted to the shape of the first bending section 13, and the terminal positioning groove 3391 of the terminal positioning seat 339 is used to position the second terminal 16. Through these structures, the inductor coil 1 is accurately fixed on the positioning jig 33, and it is ensured that the first terminal 15 and the second terminal 16 are accurately positioned at the positions to be welded.

[0041] Reference Figure 5Specifically, the inner coil 11 is placed in the annular positioning cavity 335 formed between the inner positioning post 333 and the positioning ring 334; the outer coil 12 of the inductor 1 is placed on the positioning ring 334, and the inner side wall of the outer coil 12 abuts against the inner side wall of the positioning ring 334. The ends of the inner coil 11 and the outer coil 12 both abut against the upper surface of the supporting block 332, and the connecting wire is placed in the positioning cavity. Further, the positions of the inductor 1, the first terminal 15, and the second terminal 16 are adjusted so that the first bend section 13 of the inductor 1 is located in the first positioning channel 3373, the second bend section 14 of the inductor 1 is located in the second positioning channel 3381, the bottom end of the first terminal 15 abuts against the top of the inner positioning post 333, and the second terminal 16 is located in the terminal positioning groove 3391.

[0042] Step 3: Start the welding device Reference Figure 4 , when the inductor coil 1 in a positioning mechanism 3 is positioned, the first drive assembly 32 in each positioning mechanism 3 starts working. During operation, the first motor 324 drives the first driving wheel 321 to rotate. Since the first belt 323 is wrapped around the first driving wheel 321 and the first driven wheel 322, the rotation of the first driving wheel 321 will drive the first belt 323 to move. Because one side of the first belt 323 is fixedly connected to the drive seat, and the drive seat is fixed to the lower surface of the first movable seat 31, the movement of the first belt 323 will cause the drive seat to move accordingly, thereby driving the first movable seat 31 and the positioning fixture 33 to move along the second direction, moving the positioning fixture 33 on the first movable seat 31 to the bottom of the support seat 22 so that the welding mechanism 4 can operate. Through the cooperation of the first guide rail 23 and the first slider, the shaking and deviation of the first movable seat 31 during the movement can be effectively reduced, ensuring that the positioning fixture 33 always maintains a stable motion trajectory, further improving the positioning accuracy of the inductor coil 1.

[0043] Reference Figure 3 and Figure 6 At the same time, the welding mechanism 4 begins to operate. The second drive assembly 42 is disposed within the crossbeam 221. The structure of the second drive assembly 42 is identical to that of the first drive assembly 32. It is used to drive the second movable base 41 to reciprocate in the first direction, moving the second movable base 41 above the positioning mechanism 3. The lifting drive assembly 44 is a cylinder, disposed on the second movable base 41, and is used to drive the lifting base 43 up and down, driving the welding assembly 45 to descend to a suitable height.

[0044] Reference Figure 6 and Figure 7During the soldering process, the winding mechanism 6 continuously winds the tin wire. The tin wire on the reel is first guided and steered by two guide wheels before being transferred to the wire feeding mechanism 5. The third drive assembly 53 of the wire feeding mechanism 5 drives the first rotating shaft 511 to rotate, driving the first wire feeding wheel 512 to rotate. At the same time, the adjustment assembly 54 drives the swing seat 542 to swing around the first mounting rod 541 through the rotation of the eccentric wheel 544, causing the second rotating shaft 521 to drive the second wire feeding wheel 522 to swing, changing the spacing between the first wire feeding wheel 512 and the second wire feeding wheel 522, thereby clamping and releasing the tin wire and precisely controlling the transmission speed and wire feeding amount of the tin wire. With the cooperation of the first wire feeding wheel 512 and the second wire feeding wheel 522, the tin wire is transferred to the guide tube 462 of the guide assembly 46. The guide tube 462 is tilted with its bottom end facing the soldering iron 453, ensuring that the tin wire can be accurately transferred to the soldering iron 453 and providing the necessary soldering materials for the soldering process. Finally, the electric soldering iron 453 melts the tin wire and solders the first connecting terminal 15 to the first bending section 13 , while soldering the second connecting terminal 16 to the second bending section 14 .

[0045] Reference Figure 3 Because the welding device is equipped with two positioning mechanisms 3, while the inductor 1 in one positioning mechanism 3 is being welded, the operator can simultaneously place and position the inductor 1 to be welded on the other positioning mechanism 3. When welding of one inductor 1 is completed, the welding mechanism 4 can immediately move to the other already positioned inductor 1 to continue welding, without having to wait for the operator to reposition and reposition the inductor 1. This parallel operation greatly improves overall welding efficiency and reduces production cycle time.

[0046] Example 2 This embodiment discloses a welding device, referring to Figure 3 and Figure 4 The welding device includes a machine base 2, a positioning mechanism 3, a welding mechanism 4, a winding mechanism 6, a guide mechanism 7, and a wire feeding mechanism 5. The machine base 2 includes a base 21 and a support base 22. The support base 22 is fixed to the upper surface of the base 21. The positioning mechanism 3 is arranged on the base 21 and is used to position the inductor 1. The support base 22 includes a crossbeam 221 and two support rods 222. The two support rods 222 extend in a vertical direction. The bottom end of each support rod 222 is fixedly connected to the upper surface of the base 21, and the top end of each support rod 222 is fixedly connected to the lower surface of the crossbeam 221. The welding mechanism 4, the winding mechanism 6, the guide mechanism 7, and the wire feeding mechanism 5 are all arranged on the crossbeam 221. The welding mechanism 4 is used to weld the terminal to the inductor 1. The winding mechanism 6 is used to wind the tin wire and transmit the thin wire to the wire feeding mechanism 5 through the guide mechanism 7. The wire feeding mechanism 5 is used to transmit the tin wire to the welding mechanism 4 to provide the necessary welding materials for the welding process.

[0047] Reference Figure 3 and Figure 4 In this embodiment, there are two positioning mechanisms 3, which are spaced apart along the first direction. Each positioning mechanism 3 includes a first movable base 31, a first drive assembly 32, and a positioning fixture 33. The first movable base 31 is slidably engaged with the base 21. The first drive assembly 32 is disposed on the base 21 and is used to drive the first movable base 31 to move along the second direction. The positioning fixture 33 is fixed to the first movable base 31 and is used to position the inductor 1.

[0048] Reference Figure 4 Specifically, the first drive assembly 32 includes a first driving pulley 321, a first driven pulley 322, a first belt 323, and a first motor 324. The first motor 324 is fixed to the lower surface of the base 21. The output shaft of the first motor 324 passes through the base 21 and is rotatably connected to the base 21. The first driving pulley 321 is sleeved on the output shaft of the first motor 324 and is fixedly connected to the output shaft of the first motor 324. The first driven pulley 322 is rotatably connected to the base 21. The first belt 323 is arranged to be looped between the first driving pulley 321 and the first driven pulley 322. A drive base is fixedly provided on the lower surface of the first movable base 31. The first belt 323 on one side passes through the drive base and is fixedly connected to the drive base. During operation, the first motor 324 drives the first driving pulley 321 to rotate. Since the first belt 323 is looped between the first driving pulley 321 and the first driven pulley 322, the rotation of the first driving pulley 321 drives the first belt 323 to move. Because one side of the first belt 323 is fixedly connected to the drive base, which is fixed to the lower surface of the first movable base 31, the movement of the first belt 323 causes the drive base to move accordingly, thereby driving the first movable base 31 and the positioning fixture 33 to move in the second direction. This drive method has a simple structure and smooth transmission. It can accurately control the movement distance and speed of the first movable base 31, thereby achieving precise positioning of the inductor coil 1, ensuring the accuracy of the welding position, and improving welding quality.

[0049] Reference Figure 4 For each positioning mechanism 3, two first guide rails 23 are fixedly mounted on the upper surface of the base 21. These two first guide rails 23 extend in the second direction. A corresponding first slider is fixedly mounted on the lower surface of each first movable seat 31. The first guide rails 23 correspond to the first sliders one by one, passing through the first sliders. The first sliders 23 slide in a sliding engagement with the first guide rails 23. The coordination between the first guide rails 23 and the first sliders effectively reduces the shaking and offset of the first movable seat 31 during movement, ensuring that the positioning jig 33 maintains a stable motion trajectory. This further improves the accuracy of the inductor coil 1's positioning and provides reliable support for subsequent welding operations.

[0050] Reference Figure 3 The positioning mechanism 3 also includes a protective cover 34, which is fixed to the upper surface of the base 21. The first driving wheel 321, the first driven wheel 322, the first belt 323, the first guide rail 23 and the first slider are all located inside the protective cover 34. The protective cover 34 provides effective physical protection for these internal structures, which can prevent external dust, debris, etc. from entering, and avoid these impurities from interfering with or damaging the normal operation of the components, thereby ensuring the stability and reliability of the function of the first driving component 32 driving the first movable seat 31 to move along the second direction, and extending the service life of related components.

[0051] Continue to refer to Figure 3 The upper surface of the protective cover 34 is also provided with two avoidance grooves 341, each of which extends along the second direction. The first movable seat 31 passes through the two avoidance grooves 341 at the same time. The first movable seat 31 and the avoidance grooves 341 are slidably matched and have a clearance fit. The two avoidance grooves 341 prevent the first movable seat 31 from interfering with the protective cover 34 during the movement along the second direction, thereby protecting both the first movable seat 31 and the protective cover 34. The provision of the protective cover 34 not only protects the internal parts, but the avoidance grooves 341 also ensure the normal movement of the first movable seat 31, making the structure of the entire positioning mechanism 3 more compact and reasonable, and improving the overall performance and reliability of the device.

[0052] Reference Figure 2 、 Figure 4 and Figure 5The positioning fixture 33 includes a base plate 331, a supporting block 332, an inner positioning column 333 and a positioning ring 334. The supporting block 332 is fixed to the surface of the first base plate 331 by a plurality of bolts, and the inner positioning column 333 and the positioning ring 334 are both fixed to the surface of the supporting block 332 by bolts. An annular positioning cavity 335 for positioning the inner coil 11 is formed between the inner positioning column 333 and the positioning ring 334. A avoidance cavity 336 for accommodating the connecting wire is also provided on the positioning ring 334. The length direction of the avoidance cavity 336 is the same as the length direction of the positioning ring 334, and both ends of the avoidance cavity 336 are open. The avoidance cavity 336 can effectively prevent the connecting wire from being squeezed or interfered with during the bending process. The avoidance cavity 336 allows the connecting wire to stretch freely during the bending operation and will not be damaged by squeezing, thereby ensuring the integrity and conductive performance of the connecting wire, while also improving the assembly quality and production efficiency of the inductor coil 1. The inner positioning post 333 is located inside the positioning ring 334. The axis of the inner positioning post 333 coincides with the axis of the positioning ring 334. The diameter of the inner positioning post 333 is smaller than the inner diameter of the positioning ring 334. When the staff places the inductor 1 on the first positioning seat 337, the inner coil 11 is located in the annular positioning cavity 335, and the outer coil 12 is sleeved on the positioning ring 334. The inner side wall of the outer coil 12 abuts against the inner side wall of the positioning ring 334. The ends of the inner coil 11 and the outer coil 12 both abut against the upper surface of the supporting block 332. At the same time, the connecting wire is located in the avoidance cavity 336. This positioning method can accurately fix the inductor 1 on the positioning fixture 33, ensure the position stability of the inductor 1 during the welding process, and avoid welding failure or poor welding quality due to movement of the inductor 1.

[0053] Reference Figure 5A first positioning seat 337 is also fixedly provided on the upper surface of the base plate 331. The first positioning seat 337 includes a first positioning block 3371 and a terminal positioning column 3372. The first positioning block 3371 is fixed to the upper surface of the carrier block 332, and the terminal positioning column 3372 is fixed to the upper surface of the first positioning block 3371. A first positioning channel 3373 is defined on the positioning seat. The shape of the first positioning channel 3373 matches the shape of the first bending section 13. When the inductor 1 is placed in the annular positioning cavity 335, the first bending section 13 is exactly located in the first positioning channel 3373, and the top of the first bending section 13 extends in the vertical direction. When the staff member places the first terminal 15 on the top of the first bending section 13, the first terminal 15 descends under the action of its own weight. When the bottom end of the first terminal 15 is connected to the top of the terminal positioning column 3372, the first terminal 15 is exactly in the position to be welded. The setting of the first positioning channel 3373 can accurately position the first bending section 13, ensuring that the first terminal 15 can be accurately sleeved on the first bending section 13 and located at the correct position to be welded, thereby improving the accuracy and efficiency of welding.

[0054] Reference Figure 1 and Figure 5 , a second positioning seat 338 and a terminal positioning seat 339 are also fixedly provided on the upper surface of the base plate 331. A second positioning channel 3381 is provided on the second positioning seat 338, and a terminal positioning groove 3391 is provided on the terminal positioning seat 339. When the inductor coil 1 is placed in the annular positioning cavity 335, the second bending section 14 is just located in the second positioning channel 3381. At the same time, when the staff puts the second terminal 16 on the second bending section 14 and moves it to the position of the terminal positioning groove 3391, the outer wall of the second terminal just abuts against the inner wall of the terminal positioning groove 3391, and at this time the second terminal 16 is just located at the position to be welded. The setting of the second positioning seat 338 and the terminal positioning seat 339 further ensures the positioning accuracy of the second terminal 16, so that the second terminal 16 can be accurately located at the position to be welded, and complete the welding operation together with the first terminal 15, thereby improving the positioning accuracy and welding quality of the entire welding device.

[0055] Reference Figure 6The welding mechanism 4 includes a second movable seat 41, a second drive assembly 42, a lifting seat 43, a lifting drive assembly 44 and a welding assembly 45. The second movable seat 41 is slidably matched with the crossbeam 221, and the second drive assembly 42 is arranged inside the crossbeam 221. The second drive assembly 42 is used to drive the second movable seat 41 to move back and forth along the first direction. The structure of the second drive assembly 42 is exactly the same as that of the first drive assembly 32, and will not be repeated here. The lifting seat 43 is slidably matched with the second movable seat 41, and the lifting drive assembly 44 is arranged on the second movable seat 41. The lifting drive assembly 44 is used to drive the lifting seat 43 to move up and down. The specific lifting drive assembly 44 is a cylinder. As the lifting drive assembly 44, the cylinder has the advantages of fast response speed, high control accuracy, and simple structure. It can quickly and accurately drive the lifting seat 43 to move up and down, meet the requirements for height adjustment of the welding assembly 45 during welding, and improve welding efficiency and quality. The welding assembly 45 is disposed on the lifting base 43 . The welding assembly 45 is used to weld the first connecting terminal 15 to the first bending section 13 , and is also used to weld the second connecting terminal 16 to the second bending section 14 .

[0056] Reference Figure 6 In this embodiment, the welding assembly 45 includes an adjustment block 451, a clamping block 452, and an electric soldering iron 453. The adjustment block 451 is fixed to the lifting base 43. The adjustment block 451 is provided with an adjustment slot 454 extending therethrough. The adjustment slot 454 is in the shape of a strip or an arc. The surface of the clamping block 452 abuts against the surface of the clamping block 452. A bolt is passed through the adjustment slot 454. The bolt cooperates with the screw of the clamping block 452, and the electric soldering iron 453 is fixedly connected to the clamping block 452. The bolt can slide freely along the length of the adjustment slot 454, thereby driving the clamping block 452 to adjust the angle or position within a specific range. When the position of the electric soldering iron 453 needs to be adjusted, it is only necessary to loosen the bolt, move the clamping block 452 to the desired position, and then retighten the bolt. Not only does this make adjusting the position of soldering iron 453 simple and convenient, but the tight fit between the bolt and the screw hole also ensures the stability of clamping block 452 after adjustment, thereby ensuring the positional accuracy of soldering iron 453 during operation. Adjusting block 451 and clamping block 452 can flexibly adjust the position and angle of soldering iron 453 according to different welding requirements, improving the versatility and adaptability of the welding device and ensuring consistent and stable welding quality.

Specifically, the winding mechanism 6 is a reel, rotatably connected to the support 47 and used to wind the solder wire. The guide mechanism 7 includes two guide wheels, both of which are rotatably connected to the support 47. The wire feeding mechanism 5 is mounted on the support 47 and is used to deliver the solder wire to the soldering assembly 45.

[0058] Reference Figure 7 and Figure 5 The wire feeding mechanism 5 includes a first rotating assembly 51, a second rotating assembly 52, a third driving assembly 53, an adjusting assembly 54, and a linkage assembly. The first rotating assembly 51 includes a first rotating shaft 511 and a first wire feeding wheel 512. The first rotating shaft 511 extends along the second direction and passes through the support 47 and is rotatably connected to the support 47. The first wire feeding wheel 512 is sleeved on the first rotating shaft 511 and fixedly connected to the first rotating shaft 511. The third driving assembly 53 is used to drive the first rotating shaft 511 to rotate. Specifically, the third drive assembly 53 includes a driving gear 531, a driven gear 532, a first linkage gear 533 and a second motor 534. The second motor 534 is fixed in the cavity of the support 47. The output shaft of the second motor 534 passes through the support 47 and is rotatably connected to the support 47. The driving gear 531 is sleeved on the output shaft of the second motor 534 and fixedly connected to the output shaft of the second motor 534. The driven gear 532 is rotatably connected to the support 47. The first linkage gear 533 is sleeved on the first rotating shaft 511 and fixedly connected to the first rotating shaft 511. The driven gear 532 is located between the driving gear 531 and the first linkage gear 533. The third drive assembly 53 of this gear transmission method has the advantages of high transmission efficiency, accurate transmission ratio, and compact structure. Through the mutual cooperation of multiple gears, it can more stably and reliably drive the first rotating shaft 511 and the second rotating shaft 521 to rotate, and then drive the first wire feeding wheel 512 and the second wire feeding wheel 522 to rotate, providing power for the transmission of tin wire, and can better control the wire feeding speed and wire feeding amount, ensure the stable supply of tin wire during welding, and improve welding quality.

[0059] Reference Figure 7The adjustment assembly 54 includes a first mounting rod 541, a swing seat 542, a second mounting rod 543, an eccentric wheel 544, and a driving rod 545. The first mounting rod 541 extends in the first direction. Both ends of the first mounting rod 541 are inserted through the support 47 and are rotatably connected to the support 47. The first mounting rod 541 passes through the top of the swing seat 542, and the swing seat 542 is rotatably connected to the first mounting rod 541. The second rotating assembly 52 includes a second rotating shaft 521, a second wire feeding wheel 522, and a second linkage gear 523. The second rotating shaft 521 extends in the first direction. One end of the second rotating shaft 521 is inserted through the bottom end of the swing seat 542 and is rotatably connected to the swing seat 542. The other end of the second rotating shaft 521 extends out of the support 47. The sidewall of the support 47 is provided with an elliptical avoidance hole 471, the width of which is substantially greater than the diameter of the second rotating shaft 521. A second wire feed wheel 522 is sleeved on one end of the second rotating shaft 521 extending from the support 47 and is fixedly connected to the second rotating shaft 521. A second linkage gear 523 is sleeved on and fixedly connected to the second rotating shaft 521, and a first linkage gear 533 engages with the second linkage gear 523. A second mounting rod 543 extends in a first direction, with both ends of the second mounting rod 543 passing through the support 47 and fixedly connected to the support 47. An eccentric hole 546 is provided at an eccentric position of the eccentric wheel 544, and the second mounting rod 543 passes through the eccentric hole 546 of the eccentric wheel 544. The eccentric wheel 544 is rotatably connected to the second mounting rod 543, and the eccentric wheel 544 abuts against the side wall of the bottom end of the swinging seat 542, facing the side wall of the swinging seat 542. A drive rod 545 is fixed to the swing seat 542, with the end of the drive rod 545 extending from the support 47 away from the swing seat 542. The adjustment assembly 54 rotates the eccentric wheel 544 to push the swing seat 542 about the first mounting rod 541, causing the second rotating shaft 521 to swing the second wire feed wheel 522, thereby changing the distance between the first wire feed wheel 512 and the second wire feed wheel 522, thereby clamping and releasing the solder wire. This allows precise control of the solder wire feed speed and amount, ensuring a stable supply of solder wire during the soldering process and improving soldering quality.

[0060] Reference Figure 6 and Figure 7At the same time, a guide assembly 46 is fixedly provided on the clamping block 452. The guide assembly 46 includes a fixed seat 461 and a guide tube 462. The fixed seat 461 passes through the clamping block 452 and is fixedly connected to the clamping block 452. The guide tube 462 passes through the fixed seat 461 and is fixedly connected to the fixed seat 461. Both ends of the guide tube 462 are open, and the guide tube 462 is inclined. The bottom end of the guide tube 462 faces the soldering iron 453. The tin wire wound on the winding drum first passes through the two guide wheels. The guide wheels guide and steer the tin wire so that it is transmitted along a predetermined path; then the tin wire is transmitted to the wire feeding mechanism 5. In the wire feeding mechanism 5, the third driving assembly 53 drives the first rotating shaft 511 to rotate, thereby driving the first wire feeding wheel 512 to rotate; at the same time, the adjusting assembly 54 drives the swing seat 542 to swing around the first mounting rod 541 through the rotation of the eccentric wheel 544, so that the second rotating shaft 521 drives The second wire feed wheel 522 is driven to swing, changing the spacing between the first wire feed wheel 512 and the second wire feed wheel 522, thereby clamping and releasing the tin wire. With the cooperation of the first wire feed wheel 512 and the second wire feed wheel 522, the tin wire is conveyed into the guide tube 462 of the guide assembly 46; the guide tube 462 is arranged at an angle with its bottom end facing the electric soldering iron 453. After being guided by the guide tube 462, the tin wire is finally conveyed to the electric soldering iron 453 of the welding assembly 45, providing the necessary welding materials for the welding process. The setting of the guide assembly 46 can ensure that the tin wire is accurately conveyed to the electric soldering iron 453, avoid problems such as deviation or entanglement of the tin wire during the conveyance process, ensure the smooth progress of the welding process, and improve the welding quality and efficiency.

[0061] The implementation principle of the above embodiment is as follows: First, the staff places the inductor coil 1 to be welded on the positioning jig 33 of one of the positioning mechanisms 3. The annular positioning cavity 335 in the positioning jig 33 fits tightly against the inner coil 11, ensuring that the inner coil 11 does not shake during the positioning process. At the same time, the avoidance cavity 336 on the positioning ring 334 provides a suitable accommodation space for the connecting wire to prevent the connecting wire from being squeezed or interfered with during the positioning process. The first positioning channel 3373 of the first positioning seat 337 is adapted to the shape of the first bending section 13, and the terminal positioning groove 3391 of the terminal positioning seat 339 is used to position the second terminal 16. Through these structures, the inductor coil 1 is accurately fixed on the positioning jig 33, and it is ensured that the first terminal 15 and the second terminal 16 are accurately positioned at the positions to be welded. When the positioning of the inductor coil 1 in a positioning mechanism 3 is completed, the welding preparation work is ready. At this point, the first drive assembly 32 within each positioning mechanism 3 begins operating. The first motor 324 rotates the first driving wheel 321, which, through the transmission of the first belt 323, drives the first movable seat 31 in the second direction, moving the positioning fixture 33 on the first movable seat 31 below the support seat 22 to facilitate operation of the welding mechanism 4. Simultaneously, the welding mechanism 4 begins operating. The second drive assembly 42 drives the second movable seat 41 in the first direction to above the positioning mechanism 3. The lifting drive assembly 44 lowers the lifting seat 43, driving the welding assembly 45 to the appropriate height. The soldering iron 453 in the welding assembly 45 is adjusted by the adjustment block 451 and the clamping block 452 to the optimal welding position. The adjustment slot 454 and the bolt on the adjustment block 451 cooperate with the clamping block 452 to enable the position and angle of the soldering iron 453 to be flexibly adjusted to accommodate the welding requirements of inductor coils 1 of different sizes and shapes. During the welding process, the winding mechanism 6 continuously winds the solder wire. The tin wire on the reel is first guided and diverted by two guide wheels, and then transmitted to the wire feeding mechanism 5. The third driving component 53 of the wire feeding mechanism 5 drives the first rotating shaft 511 to rotate, driving the first wire feeding wheel 512 to rotate. At the same time, the adjusting component 54 drives the swing seat 542 to swing around the first mounting rod 541 through the rotation of the eccentric wheel 544, so that the second rotating shaft 521 drives the second wire feeding wheel 522 to swing, changing the distance between the first wire feeding wheel 512 and the second wire feeding wheel 522, thereby achieving the clamping and loosening of the tin wire and accurately controlling the transmission speed and wire feeding amount of the tin wire. With the cooperation of the first wire feeding wheel 512 and the second wire feeding wheel 522, the tin wire is transmitted to the guide tube 462 of the guide assembly 46. The guide tube 462 is arranged at an angle with the bottom end facing the soldering iron 453, ensuring that the tin wire can be accurately transmitted to the soldering iron 453, providing the necessary soldering materials for the soldering process.Because the welding device is equipped with two positioning mechanisms 3, while the inductor 1 in one positioning mechanism 3 is being welded, the operator can simultaneously place and position the inductor 1 to be welded on the other positioning mechanism 3. Once welding of one inductor 1 is complete, the welding mechanism 4 can immediately move to the other already positioned inductor 1 to continue welding, eliminating the need for the operator to reposition and reposition the inductor 1. This parallel operation significantly improves overall welding efficiency and reduces production cycle time.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
