Description

Technical Field

[0002] With the continuous development of electronic technology, the performance requirements for chip inductors are getting higher and higher. Chip inductors are widely used in electronic devices, and their performance directly affects the overall performance of electronic devices. The wire winding process, as a key link in chip inductor production, plays a decisive role in the quality of the inductor.

[0003] At present, it is difficult for wire winding devices to achieve precise positioning of the wire winding position for different specifications of chip inductors. When winding multi-layer windings, due to the difficulty in precisely controlling the starting position and ending position of each layer of wire winding, situations such as wire winding overlap and uneven gaps are likely to occur. This not only affects the inductance accuracy of the inductor but may also lead to a decline in electrical performance. Moreover, the existing wire winding devices perform poorly in terms of wire winding efficiency and are difficult to meet the requirements of high-efficiency output for large-scale production.

[0016] The beneficial effects achieved: 1. This application uses multiple vertically arranged tubes, turntables, and winding assemblies to perform multi-station winding work simultaneously. Compared with single-station winding devices, the winding output per unit time is greatly increased, the winding efficiency is improved, and thus the large-scale production requirements are met. And through the precise adjustment of the position of the magnetic core by the adjustment assembly, the winding position can be accurately controlled during the production process of the chip inductor, ensuring that the winding is tight and uniform, and improving the quality and performance consistency of the chip inductor winding.

[0017] 2. The coordinated work of the pumping mechanism, buffer tank, coating box, coating roller and other components in this application can accurately apply the insulating glue liquid on the outside of the wire. The insulating glue liquid can not only ensure the insulation performance between the inductor windings, but also increase the stability between the windings by using the viscosity of the glue liquid, which can prevent the wire from loosening and shifting in the subsequent process, and further ensure the quality of the chip inductor winding.

[0018] 3. This application monitors the inductance on the magnetic core in real time through a detection sensor, enabling timely detection of problems during the winding process. Once the inductance does not meet the production standard, the system can quickly determine and record it, avoiding the production of a large number of unqualified products and ensuring the winding quality of mass-produced chip inductors.

[0033] An embodiment of the present application discloses an automatic wire winding device and a production method for the production of chip inductors.

[0034] Embodiment 1 Please refer to Figures 1 to 10 , in an embodiment of the present application, an automatic wire winding device for the production of chip inductors includes a support frame 100. A plurality of vertically arranged tubes 101 are rotatably connected to the support frame 100. Turntables 102 are fixedly connected to the vertically arranged tubes 101. The adjacent two turntables 102 are drivingly connected. A first driving member 103 is drivingly connected to the outermost turntable 102. Winding assemblies 200 are installed on the turntables 102. Wire reels 900 are clamped on the winding assemblies 200. Wires 901 are wound on the wire reels 900. A conveying assembly 300 is installed on the support frame 100 corresponding to the winding assemblies 200. A magnetic core 902 is placed on the conveying assembly 300. An adjustment assembly 400 is arranged at the center of the vertically arranged tube 101 corresponding to the magnetic core 902. A clamping assembly 500 and a cutting assembly 600 are respectively installed on the support frame 100 on the outer side of the conveying assembly 300 corresponding to the wire 901. One end of the wire 901 away from the wire reel 900 is electrically connected to the clamping assembly 500. One end of the wire 901 close to the wire reel 900 is electrically connected to the winding assembly 200. The winding assembly 200 and the clamping assembly 500 are electrically connected to a control system 700.

[0035] First, install the wire reel 900 with the wire 901 coiled thereon on the winding assembly 200, and pass the wire 901 through the winding assembly 200. Then, control the clamping assembly 500 by the control system 700 to clamp one end of the wire 901 away from the wire reel 900 to ensure the stable position of the wire 901 during winding. The control system 700 simultaneously controls the conveying assembly 300 to convey the magnetic core 902 to the lower end of the winding assembly 200. When the conveying assembly 300 conveys the magnetic core 902 to the lower end of the winding assembly 200, start the first driving member 103, which transmits power to the outermost turntable 102 that is drivingly connected thereto. Since the adjacent two turntables 102 are drivingly connected to each other, the rotation of one turntable 102 will drive the other turntables 102 to rotate synchronously, thereby causing the vertical pipes 101 fixed on the turntables 102 to rotate on the support frame 100. The winding assembly 200 rotates with the turntable 102, driving the wire reel 900 to rotate, and the wire 901 is drawn out from the wire reel 900. As the winding assembly 200 rotates, the wire 901 starts to wind around the magnetic core 902. At the same time, the adjusting assembly 400 adjusts the height position of the magnetic core 902, so that the wire 901 can wind around the magnetic core 902 with an up-and-down swing. When the winding reaches the predetermined number of turns or length, the control system 700 controls the cutting assembly 600 to act and cut the wire 901. Subsequently, the clamping assembly 500 releases the wire 901, and the conveying assembly 300 sends out the wound magnetic core 902 to complete one winding process. Then, a new magnetic core 902 is conveyed onto the conveying assembly 300 to start the next round of winding operation.

[0036] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the first driving member 103 includes a first stepping motor 104, a driving gear 105 is fixedly installed on the output shaft of the first stepping motor 104, a toothed ring 106 is fixedly embedded on the outer side surface of the turntable 102, the adjacent two toothed rings 106 are meshed with each other, and the toothed ring 106 on one of the outermost turntables 102 is meshed and driven with the driving gear 105.

[0037] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the control system 700 includes detection sensors 701 corresponding to the winding assembly 200 one by one. The detection sensors 701 are respectively fixedly installed at positions corresponding to the magnetic core 902 inside the adjusting assembly 400. The first driving member 103, the conveying assembly 300, the adjusting assembly 400, and the cutting assembly 600 are all electrically connected to the control system 700.

[0038] During the working process, the detection sensor 701 is fixedly installed at a position corresponding to the magnetic core 902 inside the adjustment component 400 and corresponds to the winding component 200 one by one. During the wire winding process, the detection sensor 701 monitors the inductance of the magnetic core 902 in real time, and transmits the monitored signal to the control system 700 in real time. The control system 700 issues corresponding instructions to the first driving member 103, the conveying component 300, the adjustment component 400, and the cutting component 600 according to the inductance signal, in combination with the preset wire winding parameters and processes. If the number of wire windings or the length reaches the predetermined value, the control system 700 will control the cutting component 600 to act. At the same time, the control system 700 will also make a comparison based on the information fed back by the detection sensor 701, that is, whether the inductance meets the standard when the number of wire windings or the length reaches the predetermined value, ensuring the production accuracy.

[0039] In a specific embodiment of the present application, the detection sensor 701 adopts a sensor based on the giant magnetoresistance effect. The giant magnetoresistance effect refers to the fact that the resistance of some materials will change significantly under the action of a magnetic field. The sensor based on the giant magnetoresistance effect utilizes this characteristic to detect the magnetic field, thereby realizing the measurement of inductance. Such sensors are usually made of materials with giant magnetoresistance characteristics as sensitive elements. When the external magnetic field (generated by the inductance) changes, the resistance value of the sensitive element changes accordingly. By measuring the change in the resistance value and combining relevant algorithms, the inductance can be calculated.

[0040] It can be understood that in other specific embodiments of the present application, the detection sensor 701 can also adopt a fluxgate sensor, which utilizes the magnetic saturation characteristic of high-permeability soft magnetic materials under the action of an alternating magnetic field to detect the magnetic field change, and then measures the inductance.

[0041] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the winding component 200 includes a mounting frame 201. The mounting frame 201 is fixedly installed on the turntable 102. An installation groove 202 for installing the wire coil 900 is provided on the mounting frame 201. Both the wire coil 900 and the mounting frame 201 are made of conductive materials. One end of the wire 901 is electrically connected to the wire coil 900. A conductive ring 203 fixedly installed on the vertical pipe 101 is rotatably connected to the mounting frame 201. The conductive ring 203 is electrically connected to the control system 700.

[0042] A wire threading hole 204 is provided on the turntable 102 corresponding to the wire reel 900. A conduit 205 is fixedly installed inside the wire threading hole 204. The conduit 205 penetrates through the lower end of the wire threading hole 204 and is installed with a coating box 206. A coating roller 207 is rotatably connected inside the coating box 206. An outlet nozzle 208 is installed at the lower end of the coating box 206. The outlet nozzle 208 is in sealed sliding connection with the wire 901. The conduit 205 is fixedly connected with a buffer tank 209 in a sealed manner. The buffer tank 209 is fixedly installed on the turntable 102. The buffer tank 209 is in sealed communication with a pumping mechanism 800, and the pumping mechanism 800 is in communication with the external insulating glue.

[0043] During the working process, the wire reel 900 is installed in the installation groove 202 of the mounting bracket 201. Since both the wire reel 900 and the mounting bracket 201 are made of conductive materials, and one end of the wire 901 is electrically connected to the wire reel 900, this provides a path for the current transmission of the wire 901 during the winding process. The conductive ring 203 rotatably connected to the mounting bracket 201 is fixed on the vertical pipe 101, and the conductive ring 203 is electrically connected to the control system 700. When the turntable 102 rotates, it drives the mounting bracket 201 and the wire reel 900 to rotate together. The conductive ring 203 can remain stationary relative to the vertical pipe 101 during the rotation process, continuously providing a stable current connection for the wire 901, ensuring the stable supply of current during the winding process and meeting the current requirements in the inductor production.

[0044] Meanwhile, when the wire 901 passes through the conduit 205 during the winding process, the insulating glue will flow along with the wire 901. Inside the coating box 206 connected to the lower end of the conduit 205, the rotating coating roller 207 evenly coats the insulating glue on the surface of the wire 901. The coated wire 901 passes through the outlet nozzle 208. The outlet nozzle 208 is in sealed sliding connection with the wire 901, which can not only ensure that the insulating glue does not leak but also allow the wire 901 to pass through smoothly. When the turntable 102 rotates to drive the wire reel 900 to wind around the magnetic core 902, the wire 901 coated with the insulating glue gradually winds around the magnetic core 902, completing the winding process with an insulating layer.

[0045] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the conveying component 300 includes support frames 301 fixedly installed at both ends of the support frame 100. Electric rollers 302 and driven rollers 303 are respectively installed on the support frames 301. The electric roller 302 is electrically connected to the control system 700. A conveyor belt 304 is drivingly connected between the electric roller 302 and the driven roller 303. A plurality of placement holes 305 for placing the magnetic cores 902 are formed in the conveyor belt 304. The distance between adjacent two placement holes 305 is equal to the distance between adjacent two vertical tubes 101. A first support plate 306 fixedly connected to the inside of the support frame 100 to prevent the magnetic cores 902 from falling out of the placement holes 305 is provided on the inner side surface of the conveyor belt 304. An avoidance hole 307 corresponding to the adjustment component 400 is formed in the first support plate 306.

[0046] During the working process, the control system 700 sends an operation instruction to the electric roller 302, and the electric roller 302 is powered on and starts. Since the electric roller 302 and the driven roller 303 are drivingly connected through the conveyor belt 304, when the electric roller 302 rotates, it drives the conveyor belt 304 to perform a cyclic movement along the support frame 301 by relying on the friction force. The magnetic cores 902 are pre-placed in the placement holes 305 formed in the conveyor belt 304. The distance between adjacent two placement holes 305 is equal to the distance between adjacent two vertical tubes 101, ensuring that the magnetic cores 902 can be accurately aligned with the lower ends of the vertical tubes 101 during the conveying process. When the conveyor belt 304 operates, it drives the magnetic cores 902 in the placement holes 305 to move synchronously. During the movement, the first support plate 306 located on the inner side surface of the conveyor belt 304 plays a supporting role to prevent the magnetic cores 902 from falling out of the placement holes 305. When the magnetic cores 902 move to the corresponding position of the adjustment component 400, the magnetic cores 902 pass through the avoidance holes 307 formed in the first support plate 306 and receive the adjustment of the height position by the adjustment component 400 to meet the winding requirements.

[0047] Please refer to Figures 1 to 10In a specific embodiment of the present application, the adjustment component 400 includes an elastic support rod 401 corresponding to the vertical tube 101 one by one, the support frame 100 is fixedly installed with a second support plate 402, the elastic support rod 401 is fixedly installed on the second support plate 402, the top of the elastic support rod 401 is fixedly connected with a support disk 403, the detection sensor 701 is installed inside the support disk 403, the inside of the vertical tube 101 is sealed and slidably connected with a push rod 404, the top of the support frame 100 is rotatably connected with the push rod 404, the drive shaft 405 is fixedly installed with a cam 406 corresponding to the push rod 404, the drive shaft 405 is transmission-connected with a second drive member 407, the second drive member 407 is electrically connected to the control system 700, the top of the push rod 404 is abutted against the cam 406, the bottom of the push rod 404 is abutted against the magnetic core 902, and the outer side of the push rod 404 is transmission-connected with the pumping mechanism 800.

[0048] During operation, the control system 700 sends a command to the second driving member 407, and the second driving member 407 starts and drives the driving shaft 405 to rotate. Since the cam 406 is fixedly mounted on the driving shaft 405, the cam 406 rotates synchronously with the driving shaft 405. When the cam 406 rotates, its eccentric structure will produce a periodic pressing effect on the push rod 404 abutting therewith. Under the pressure of the cam 406, the push rod 404 performs an up and down sealing sliding movement inside the vertical pipe 101. Because the bottom of the push rod 404 abuts against the magnetic core 902, the up and down movement of the push rod 404 can drive the magnetic core 902 to move up and down synchronously, thereby adjusting the height position of the magnetic core 902. During the adjustment process, the support plate 403 is fixed on the second support plate 402 by the elastic support rod 401, providing stable support for the magnetic core 902. The outer side of the push rod 404 is transmission-connected to the pumping mechanism 800. Furthermore, the power generated by the upward and downward movement of the push rod 404 can be used to drive the pumping mechanism 800, thereby controlling the pumping mechanism 800 to enter a working state.

[0049] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the second driving member 407 includes a second stepper motor 408, a driving pulley 409 is fixedly mounted on the output shaft of the second stepper motor 408, a driven pulley 410 is mounted on the driving shaft 405 corresponding to the driving pulley 409, and a timing belt 411 is connected between the driving pulley 409 and the driven pulley 410.

[0050] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the pumping mechanism 800 includes cylinder sleeves 801 fixedly connected to the top of the support frame 100 and corresponding to the vertical pipes 101 one by one. The bottom of the cylinder sleeve 801 is hermetically and rotatably connected to the top of the vertical pipe 101. The top of the cylinder sleeve 801 is hermetically connected to a cylinder head 802. A sliding hole 803 is formed in the cylinder head 802. The top pressure rod 404 is hermetically and slidably connected to the cylinder head 802 through the sliding hole 803. Inside the cylinder sleeve 801, a first piston plate 804 and a second piston plate 805 arranged side by side up and down are hermetically and slidably connected. Both the first piston plate 804 and the second piston plate 805 are fixedly connected to the top pressure rod 404. Liquid inlet holes 806 penetrating through both ends are formed in both the first piston plate 804 and the second piston plate 805. A plugging block 807 for plugging the liquid inlet hole 806 is arranged at one end of the first piston plate 804 close to the second piston plate 805. A first spring 808 is arranged at one end of the second piston plate 805 close to the first piston plate 804. The first spring 808 abuts between the second piston plate 805 and the plugging block 807. An input pipe joint 809 is arranged at a position on the outer side of the cylinder sleeve 801 close to its top. All the input pipe joints 809 are connected to the same input pipe 810. A one-way input valve 811 is connected to the input pipe 810. One end of the one-way input valve 811 far from the input pipe 810 is communicated with a container for storing insulating glue liquid outside. An output cavity 812 hermetically communicated with the buffer tank 209 is formed at the top of the vertical pipe 101. A second spring 813 abutting against the second piston plate 805 is installed inside the output cavity 812.

[0051] During the working process, when the top pressure rod 404 moves up and down in the vertical pipe 101 under the action of the cam 406, since both the first piston plate 804 and the second piston plate 805 are fixedly connected to the top pressure rod 404, the first piston plate 804 and the second piston plate 805 will move up and down synchronously with the top pressure rod 404. During the downward movement, the input pipe joint 809 at the top of the cylinder sleeve 801 is communicated with a container for storing insulating glue liquid outside through the input pipe 810 and the one-way input valve 811. Under the negative pressure generated by the downward movement of the first piston plate 804 and the second piston plate 805, the insulating glue liquid enters the cavity above the first piston plate 804 through the input pipe joint 809 and the liquid inlet hole 806. During the upward movement, the pressure in the space above the first piston plate 804 increases, so that the plugging block 807 on the first piston plate 804 disengages from the liquid inlet hole 806 under the action of the pressure, the liquid inlet hole 806 is opened, and the insulating glue liquid will enter the buffer tank 209 through the output cavity 812.

[0052] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the clamping assembly 500 includes a third support plate 501 fixedly installed inside the support frame 100. On one side of the third support plate 501 close to the conveying assembly 300, a fixed clamping plate 502 is fixedly connected. On the side of the third support plate 501 far from the conveying assembly 300, a first telescopic member 503 is fixedly connected. The first telescopic member 503 is electrically connected to the control system 700. A sliding clamping plate 504 is fixedly installed at the telescopic end of the first telescopic member 503. The sliding clamping plate 504 is arranged parallel to the fixed clamping plate 502. One end of the wire 901 far from the wire reel 900 is clamped between the sliding clamping plate 504 and the fixed clamping plate 502. A conductive block 505 is fixedly installed on the fixed clamping plate 502 corresponding to the wire 901. The conductive block 505 is electrically connected to the control system 700. A plurality of puncturing teeth 506 arranged in parallel are fixedly and conductively connected to the conductive block 505 corresponding to the wire 901.

[0053] During the working process, the control system 700 sends an instruction to the first telescopic member 503, and the first telescopic member 503 starts. When it is necessary to clamp the wire 901, the telescopic end of the first telescopic member 503 extends, pushing the sliding clamping plate 504 to move towards the fixed clamping plate 502. One end of the wire 901 far from the wire reel 900 is located between the sliding clamping plate 504 and the fixed clamping plate 502. As the sliding clamping plate 504 approaches, the wire 901 is gradually clamped, realizing a firm clamping of the wire 901, ensuring that the wire will not loosen or displace during the winding process, and guaranteeing the stability of the winding work.

[0054] When the wire 901 is clamped between the sliding clamping plate 504 and the fixed clamping plate 502, the puncturing teeth 506 fixed on the conductive block 505 come into contact with the wire 901. Since the puncturing teeth 506 are sharp and fixedly and conductively connected to the conductive block 505, the puncturing teeth 506 will puncture the insulating layer of the wire 901 and form a direct conductive connection with the conductive core of the wire 901. In this way, through the conductive block 505 and the puncturing teeth 506, a stable electrical connection is established between the wire 901 and the control system 700, enabling the control system 700 to monitor and control the current during the winding process, meeting the precise control requirements of the current during the winding of the chip inductor.

[0055] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the shearing assembly 600 includes a fourth support plate 601 fixedly installed on the support frame 100. A second telescopic member 602 is fixedly installed on the fourth support plate 601. The second telescopic member 602 is electrically connected to the control system 700. A fixed tool holder 603 is fixedly installed at the telescopic end of the second telescopic member 602. A sliding tool holder 604 is slidably connected to the fixed tool holder 603. A chopping knife 605 is fixedly installed on the sliding tool holder 604 corresponding to each winding assembly 200. A bearing block 606 is fixedly connected to the fixed tool holder 603 corresponding to the chopping knife 605. An inclined connecting rod 607 is hinged to the side of the sliding tool holder 604 away from the chopping knife 605. One end of the inclined connecting rod 607 away from the sliding tool holder 604 is hinged to the fourth support plate 601.

[0056] During the working process, when the winding process is completed, the control system 700 sends an instruction to the second telescopic member 602, and the second telescopic member 602 starts. The telescopic end of the second telescopic member 602 extends, pushing the fixed tool holder 603 forward. Since the sliding tool holder 604 is slidably connected to the fixed tool holder 603, and one end of the inclined connecting rod 607 is hinged to the sliding tool holder 604 and the other end is hinged to the fourth support plate 601. When the fixed tool holder 603 moves forward, the inclined connecting rod 607 will generate a component force along the sliding direction of the fixed tool holder 603 on the sliding tool holder 604 due to the hinge relationship at both ends, causing the sliding tool holder 604 to slide forward rapidly on the fixed tool holder 603.

[0057] A chopping knife 605 is fixedly installed on the sliding tool holder 604 corresponding to each winding assembly 200, and a bearing block 606 is fixedly connected to the fixed tool holder 603 corresponding to the chopping knife 605. As the sliding tool holder 604 slides forward rapidly, the chopping knife 605 quickly approaches the bearing block 606. When the chopping knife 605 contacts the bearing block 606, a shearing force is formed between the two, cutting the wire 901 located between the chopping knife 605 and the bearing block 606. Since the chopping knife 605 corresponds to the winding assembly 200 one by one, multiple wires 901 that are being wound can be cut simultaneously, improving the cutting efficiency.

[0058] Please refer to Figures 1 to 10, in a specific embodiment of the present application, both the first telescopic member 503 and the second telescopic member 602 are electric telescopic rods, and the electric telescopic rods can accurately adjust the telescopic amount and telescopic speed through the control system 700. For the first telescopic member 503, in the clamping assembly 500, the moving distance and speed of the sliding clamping plate 504 can be accurately controlled to ensure that wires 901 of different specifications can be stably and moderately clamped. For example, for thinner wires, the first telescopic member 503 can be accurately adjusted to provide a gentle and stable clamping force to avoid pinching the wires; for thicker wires, the clamping force can be accurately adjusted to an appropriate level. In the cutting assembly 600, the second telescopic member 602 is an electric telescopic rod, which can accurately control the moving speed and stroke of the fixed tool holder 603 to ensure the precise cooperation between the cutting knife 605 and the bearing block 606, realizing the precise cutting of the wire 901, improving the accuracy and consistency of the cutting process, and reducing product quality problems caused by cutting position deviation.

[0059] It can be understood that in other specific embodiments of the present application, the first telescopic member 503 and the second telescopic member 602 can also adopt devices or mechanisms such as linear motors or slider mechanisms that can generate linear motion.

[0060] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the control system 700 further includes a computer and a controller. The computer is electrically connected to the controller. The computer is connected with a control panel and a display. The controller is respectively electrically connected to the winding assembly 200, the clamping assembly 500, the detection sensor 701, the first driving member 103, the conveying assembly 300, the adjustment assembly 400, and the cutting assembly 600.

[0061] During the working process, the operator inputs various winding-related parameters to the computer through the control panel, such as the number of winding turns, winding speed, magnetic core conveying speed, clamping time and force of the clamping assembly, adjustment amplitude of the adjustment assembly, and cutting timing of the cutting assembly, etc. After receiving these parameter information, the computer processes and analyzes them, and transmits the processed instructions to the controller electrically connected thereto.

[0062] According to the instructions transmitted from the computer, the controller sends control signals to the winding assembly 200, the clamping assembly 500, the detection sensor 701, the first driving member 103, the conveying assembly 300, the adjustment assembly 400, and the cutting assembly 600 respectively. For example, the controller controls the first driving member 103 to rotate at a set speed to drive the wire reel 900 for winding operation; controls the conveying assembly 300 to run at a specific speed to accurately convey the magnetic core 902 to the designated position; controls the adjustment assembly 400 to adjust the height position of the magnetic core 902. At the same time, the controller receives the inductance of the magnetic core 902 feedback by the detection sensor 701 in real time and further controls according to the inductance information.

[0063] During the wire winding process of chip inductor production, the operating states of each component and the data collected by the detection sensor 701 will be fed back to the computer through the controller. After the computer sorts out and analyzes this data, key information such as the wire winding progress, whether the core inductance meets the standard, and whether each component is working properly will be displayed on the monitor. The operator can intuitively understand various information in the production process through the monitor so as to make decisions and adjustments in a timely manner.

[0064] Embodiment 2 In an implementation manner of the present application, a production method for chip inductor production includes the following steps: S1. Before wire winding, install the wire coil 900 on the winding component 200, and make the wire 901 on the wire coil 900 form an electrical connection with the winding component 200 to ensure that the wire 901 can transmit current normally during the subsequent wire winding process.

[0069] S24. Set the conditions and speed for the control system 700 to automatically control the adjustment component 400 to synchronously adjust the height position of the core 902.

[0070] S25. Set the conditions and timing for the control system 700 to automatically control the cutting component 600 to cut the wire 901 to ensure that the wire can be accurately cut after wire winding is completed.

[0071] S3. Automatically control the transfer component 300 through the control system 700 to align the cores 902 on the transfer component 300 with the lower ends of the vertical tubes 101 one by one to provide an accurate starting position for wire winding.

[0072] S4. Automatically control the clamping assembly 500 through the control system 700 to clamp and fix one end of the wire 901 passing through the winding assembly 200, and establish an electrical connection between the wire 901 and the clamping assembly 500, ensuring the stability of the wire during winding.

[0073] S5. Automatically control the first driving member 103 to rotate through the control system 700. Meanwhile, synchronously adjust the height position of the magnetic core 902 through the adjustment assembly 400, so that the wire 901 is evenly wound around the magnetic core 902.

[0074] S6. Automatically control the detection sensor 701 through the control system 700 to continuously detect the inductance on the magnetic core 902 in real time. If the inductance on the magnetic core 902 meets the production standard under the set number of winding turns, it is determined that the winding process is correctly completed. If the inductance on a certain magnetic core 902 does not meet the production standard under the set number of winding turns, it is determined that there is a defect in the winding process and recorded in the system. If the inductances on all the magnetic cores 902 do not meet the production standard under the set number of winding turns, it is determined that the winding process is abnormal and the machine is stopped for warning.

[0075] S7. After completing the winding of the wire 901, automatically control the first driving member 103 through the control system 700 to drive the wire 901 to rotate to a position aligned with the cutting assembly 600.

[0076] S8. Automatically control the cutting assembly 600 to cut the wire 901 through the control system 700.

[0077] S9. Automatically control the conveying assembly 300 through the control system 700, so that the wound magnetic cores 902 on the conveying assembly 300 leave the lower end of the vertical tube 101 and are aligned one by one, while aligning the new magnetic cores 902 with the lower end of the vertical tube 101 one by one.

[0078] S10. Automatically control the first driving member 103 to drive the wire 901 to rotate to a position aligned with the clamping assembly 500 through the control system 700.

[0079] S11. Repeat steps S4 to S10 until batch production is completed.

[0080] In the preliminary preparation stage, the wire reel is installed on the winding assembly and an electrical connection is established. The wire passes through the winding assembly. Subsequently, the control system parameters are comprehensively set, including the operating conditions, speeds, times, etc. of the conveying assembly, the clamping assembly, the first driving member, the adjusting assembly, and the cutting assembly. During wire winding, the control system controls the conveying assembly according to the set parameters to align the magnetic core with the lower end of the vertical tube, controls the clamping assembly to clamp the wire and conduct electricity, the first driving member drives the wire reel to rotate, and the adjusting assembly synchronously adjusts the height of the magnetic core to enable the wire to be evenly wound. During the wire winding process, the detection sensor monitors the inductance of the magnetic core in real time, and the control system determines whether the wire winding process is completed based on this. After the wire winding is completed, the control system controls the first driving member to drive the wire to align with the cutting assembly to cut the wire, and then controls the conveying assembly to let the wound magnetic core leave and load a new magnetic core, and the first driving member drives the wire to align with the clamping assembly, and so on to achieve mass production by repeating.

[0081] For the production method adopted in this application, the entire wire winding process is automatically controlled by the control system 700, and each component works in coordination without frequent manual intervention. For example, components such as the conveying assembly 300 and the first driving member 103 operate quickly according to the preset parameters, greatly shortening the wire winding time for each round, increasing the production output per unit time, and achieving efficient mass production. And by the detection sensor 701 monitoring the inductance on the magnetic core 902 in real time, problems in the wire winding process can be found in a timely manner. Once the inductance does not meet the production standard, the system can quickly determine and record it, avoiding the production of a large number of unqualified products and ensuring the consistency of the wire winding quality and the performance of the chip inductor.

[0082] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
