Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing and processing technology, and in particular to an electronic component winding device. Background Technology

[0002] Electronic components are the basic units that make up electronic circuits, including resistors, capacitors, inductors, diodes, integrated circuits, etc., used to realize functions such as signal processing and energy conversion. Electronic component winding devices are specialized equipment for automating coil winding and are widely used in the production of components such as inductors, transformers, and motors. This device, through a precision mechanical structure and control system, evenly winds wires onto a magnetic core or frame according to set parameters (such as the number of turns, density, and number of layers).

[0003] Process uniformity is a core quality indicator for electronic component winding, and its level directly affects the performance of the electronic component. Specifically, the magnitude of winding trajectory deviation directly affects process uniformity: insufficient uniformity can lead to problems such as spiral gaps and micro-gaps between layers in the coil, ultimately affecting the performance of the electronic component.

[0004] Current methods for winding coils for electronic components primarily rely on three-jaw chucks and rubber pads to provide uniform clamping force. However, these methods are ineffective for fixing and clamping irregularly shaped electronic components (such as conical or hourglass-shaped components) with varying diameters. Due to their rigid clamping, they cannot conform to non-cylindrical curved surfaces, resulting in uneven clamping force distribution, insufficient stability, and a tendency to cause localized stress concentration or component deformation, thus limiting adaptability. Furthermore, during the winding process, the winding tension may cause the electronic component to slip or tilt, leading to coaxiality deviations and causing the winding trajectory to deviate from the theoretical concentric circle. Simultaneously, when the winding reaches the tapered end of the electronic component, the coil relaxes, resulting in reduced tension and the formation of spiral micro-gaps between winding layers. This makes it impossible to dynamically adjust the coil's tension, ultimately leading to uneven winding, affecting winding accuracy, and reducing the performance of the electronic component. Summary of the Invention

[0005] This application provides an electronic component winding device that solves the technical problems in the prior art, such as insufficient adaptability, uneven clamping force of curved electronic components, large coaxiality deviation during the winding process, coil tension fluctuation, uneven winding, and reduced quality. It achieves the technical effects of improved adaptability, uniform clamping of curved components, significant reduction of coaxiality deviation, dynamic balance of coil tension, and simultaneous improvement of winding uniformity and quality.

[0006] This application provides an electronic component winding device, including a device frame, a lead coil, a coil support, a turnover winding mechanism, a coil guiding mechanism, an electronic component picking and placing mechanism, and a clamping assembly; Two clamping components are provided, which are fixed to the inside of the equipment frame respectively. Each component has a vertically placed clamping airbag. The clamping airbag includes multiple cavities arranged along its circumference, which are used to perform coaxiality correction of electronic components by pneumatic flexible clamping. The coil guiding mechanism includes a coil guiding block, a lead screw, a coil guiding rod, a coil guiding groove, and a wire breaking assembly; a fixing block is fixed on the top of the coil guiding block, and the fixing block dynamically balances the tension of the coil during winding by inflating it.

[0007] Furthermore, the clamping assembly includes a clamping telescopic cylinder, a connecting plate, a clamping airbag, and an adjusting air pump; The clamping telescopic cylinder is fixed inside the equipment frame; the connecting plate is a disc-shaped structure and is fixed to the telescopic end of the clamping telescopic cylinder; the clamping airbag is fixed inside the connecting plate and is on the same central axis as the clamping telescopic cylinder and the connecting plate, and is used to clamp and fix the two ends of the electronic component.

[0008] Furthermore, the clamping airbag is made of gradient hardness silicone material to enhance the fit to curved surfaces and to adapt to the fixation of electronic components with variable diameters, such as conical or hourglass shapes.

[0009] Furthermore, the clamping airbag has multiple cavities evenly distributed along its circumference inside, and each cavity is connected to a corresponding regulating air pump through an internal air passage for clamping electronic components.

[0010] Furthermore, each of the aforementioned bladder cavities is embedded with a sensor. The sensor is used to detect the pressure on different positions of the clamping airbag when the electronic component is misaligned during the fixing or winding process. The pressure data at different positions is then transmitted to the external control system, which then issues a command to the regulating air pump at the corresponding position to control the inflation and deflation of the bladder at the corresponding position, thereby correcting the coaxiality of the misaligned electronic component.

[0011] Furthermore, the wire breaking assembly includes a fixed plate, a wire breaking telescopic cylinder, and a movable clamping block; The fixing plate is fixed on the coil guide block and is positioned opposite to the fixing block; the wire-breaking telescopic cylinder is fixed on the fixing plate and is used to drive the moving clamping block to clamp the conductor coil; the moving clamping block is fixed at the telescopic end of the wire-breaking telescopic cylinder.

[0012] Furthermore, a fixing block is fixed to the top of the coil guide block, and the fixing block includes a fixing clamp block and an adjusting block; The top of the fixed clamping block has a wedge-shaped structure, which is used to cooperate with the movable clamping block to cut the wire; the adjusting block is fixed on the coil guide block and is used to dynamically balance the coil tension.

[0013] Furthermore, the adjustment block has a hollow bladder structure, and its outer shell is made of a rigid material, including a sensing chamber and a pressure adjustment chamber; The sensing cavity is a flexible layer located near the fixed plate. It is sealed with gas and in contact with the conductor coil. It is used to indirectly reflect the coil tension by sensing changes in the pressure inside the cavity. The pressure regulating cavity is a hollow bladder structure. Its interior is connected to the wire-breaking telescopic cylinder through an external pipe. By inflating and expanding the cavity, it pushes the sensing cavity outward, causing the sensing cavity to push the conductor coil and tighten it, thereby changing the tightness of the conductor coil and compensating for tension when it is wound around a small diameter part of the electronic component.

[0014] Furthermore, a second sensor is fixed inside the sensing cavity to sense the pressure inside the sensing cavity, indirectly reflecting the real-time tension of the conductor coil during the winding process. The sensed tension data is then transmitted to the external control system, which controls the expansion of the pressure regulating cavity to dynamically balance the tension of the conductor coil.

[0015] Furthermore, the synergistic effect of the clamping airbag, air chamber, regulating air pump, sensing chamber, pressure regulating chamber, and wire-breaking telescopic cylinder in jointly controlling the real-time winding trajectory deviation correction of the conductor coil satisfies the following relationship: Coaxiality correction satisfies the following relationship:

[0016] in, This refers to the amount of pressure change that needs to be adjusted within the bladder cavity; The real-time pressure detected by sensor 1; The coaxial reference pressure is preset based on the diameter of the electronic component. The feedback gain coefficient of the control system (dimensionless) is determined by system calibration, and its typical value range is [value range missing]. ; Tension compensation satisfies the following relationship:

[0017] in, The inflation volume of the pressure regulating chamber; The real-time tension is inferred by sensor 2 based on the pressure change inside the sensing cavity; The preset ideal tension value; The proportional coefficient of the tension compensation system is determined by the structural geometry of the pressure regulating cavity (such as the elastic modulus and effective cross-sectional area of ​​the bladder), and its value ranges from [value missing]. .

[0018] One or more technical solutions provided in this application have at least the following technical effects or advantages: By using a clamping airbag, gradient hardness silicone, and a multi-cavity structure, it can adaptively conform to curved surfaces with varying diameters, such as conical or hourglass shapes. A sensor monitors pressure distribution in real time, and the control system automatically adjusts the air pressure in the airbag cavities to correct component tilt. The inflation of the pressure regulating cavity pushes the induction cavity to tighten the coil, providing real-time tension compensation. The clamping airbag corrects coaxiality, and the tension regulating block balances the varying diameter tension, collaboratively correcting winding trajectory deviations. This effectively solves the technical problems of insufficient adaptability, uneven clamping force on curved electronic components, large coaxiality deviations during winding, coil tension fluctuations, uneven winding, and reduced quality in existing technologies. It achieves improved adaptability, uniform clamping of curved components, significant reduction in coaxiality deviation, dynamic balance of coil tension, and simultaneous improvement in winding uniformity and quality.

Detailed Implementation

[0028] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0029] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figure 1 This is a schematic diagram of the overall structure of an electronic component winding device according to the present invention. The electronic component winding device of this application, through the structure of a clamping airbag 230, gradient hardness silicone, and multiple cavities 231, can adaptively conform to curved surfaces with varying diameters, such as cones / hourglasses. A sensor 250 monitors the pressure distribution in real time, and the control system automatically adjusts the air pressure in the cavities 231 to correct component tilt. The pressure regulating cavity 322 inflates, pushing the sensing cavity 321 to tighten the coil, providing real-time tension compensation. The clamping airbag 230 corrects coaxiality, and the tension regulating block 320 balances the varying diameter tension, working together to correct winding trajectory deviations. This achieves the technical effects of improved adaptability, uniform clamping of curved components, significant reduction in coaxiality deviation, dynamic balance of coil tension, and simultaneous improvement in winding uniformity and quality.

[0032] In particular, the deviation in the winding trajectory mainly manifests as a spiral gap or a micro gap between layers, which mainly stems from two core issues: coaxiality deviation (the component tilting causes the winding to be out of sync) and tension fluctuation (the coil loosening causes the winding to be uneven). Therefore, for the winding of variable diameter electronic components, it is especially important to maintain the coaxiality and the balance of the winding tension of the wire during fixing and winding.

[0033] Example 1: As Figures 1 to 6 As shown, this application discloses an electronic component winding device, which includes a device frame 100, a coil 101, a coil support 110, a rotating winding mechanism 120, a coil guiding mechanism 130, an electronic component picking and placing mechanism 140, and a clamping assembly 200. Two clamping assemblies 200 are provided, which are respectively mirror-fixed inside the equipment frame 100. Each of them has a vertically placed clamping airbag 230. The clamping airbag 230 includes multiple cavities 231 arranged along its circumference, which are used to perform coaxiality correction of electronic components by pneumatic flexible clamping. The coil guiding mechanism 130 includes a coil guiding block 131, a lead screw 132, a coil guiding rod 133, and a coil guiding groove 134; a fixing block 300 is fixed on the top of the coil guiding block 131, and the fixing block 300 dynamically balances the tension of the coil 101 during winding by inflating.

[0034] Considering that when winding irregularly shaped parts, the shape of the electronic components may cause them to tilt due to the tension of the winding wire, resulting in coaxiality deviation. This leads to the winding trajectory deviating from the theoretical concentric circle, and spiral gaps appearing between the winding layers. Figures 1 to 4 As shown, the clamping assembly 200 includes a clamping telescopic cylinder 210, a connecting plate 220, a clamping airbag 230, and an adjusting air pump 240; The clamping telescopic cylinder 210 is fixed inside the equipment frame 100; the connecting plate 220 is a disc-shaped structure and is fixed to the telescopic end of the clamping telescopic cylinder 210; the clamping airbag 230 is fixed inside the connecting plate 220 and is on the same central axis as the clamping telescopic cylinder 210 and the connecting plate 220, and is used to clamp and fix the two ends of the electronic component.

[0035] The clamping airbag 230 is made of gradient hardness silicone material to enhance the fit of curved surfaces and to adapt to the fixation of electronic components with variable diameters, such as conical or hourglass shapes.

[0036] The clamping airbag 230 has multiple cavities 231 evenly distributed along its circumference. Each cavity 231 is connected to a corresponding regulating air pump 240 through an internal air passage for clamping electronic components. By adjusting the pressure distribution in the cavities 231, the eccentric torque caused by the winding tension is counteracted in real time, achieving real-time dynamic balance.

[0037] Each of the bladder 231 has a sensor 250 embedded inside. The sensor 250 is used to detect the pressure on different positions of the clamping airbag 230 when the electronic component is misaligned during the fixing or winding process. The pressure data at different positions is then transmitted to the external control system, which then issues a command to the regulating air pump 240 at the corresponding position to control the inflation and deflation of the bladder 231 at the corresponding position, thereby correcting the coaxiality of the misaligned electronic component.

[0038] This application achieves pneumatic flexible clamping of electronic components through two mirror-mounted clamping components 200. The disc-shaped connecting plate 220 is driven by the clamping telescopic cylinder 210 to ensure that the clamping airbag 230 is coaxially aligned with the electronic component. By adapting to electronic components of different shapes (such as conical and hourglass shapes), the problem of clamping stability (coaxiality) is solved, and the winding quality is improved from the source. The clamping airbag 230 is made of gradient hardness silicone, with the hardness gradually changing from the center to the edge. The soft center fits the convex surface, and the hard edge supports the concave surface, perfectly adapting to the variable diameter curved surface such as hourglass shape. The flexible material also avoids scratching the surface of the electronic component during clamping.

[0039] like Figures 5 to 8 As shown, the wire breaking assembly 150 includes a fixed plate 151, a wire breaking telescopic cylinder 152, and a movable clamping block 153; The fixing plate 151 is fixed on the coil guide block 131 and is positioned opposite to the fixing block 300; the wire breaking telescopic cylinder 152 is fixed on the fixing plate 151 and is used to drive the moving clamping block 153 to clamp the conductor coil 101; the moving clamping block 153 is fixed at the telescopic end of the wire breaking telescopic cylinder 152.

[0040] The top of the coil guide block 131 is fixed with a fixing block 300, which includes a fixing clamping block 310 and an adjusting block 320. The fixed clamping block 310 has a wedge-shaped top end, which is used to cooperate with the movable clamping block 153 to cut the wire; the adjusting block 320 is fixed on the coil guide block 131 and is used to dynamically balance the coil tension.

[0041] The regulating block 320 is a hollow bladder structure, and its outer shell is made of a rigid material. It includes a sensing cavity 321 and a pressure regulating cavity 322. The sensing cavity 321 is a flexible layer located near the fixed plate 151. It is sealed with gas and contacts the conductor coil 101. It is used to indirectly reflect the coil tension by sensing changes in the pressure inside the cavity. The pressure regulating cavity 322 is a hollow bladder structure. Its interior is connected to the wire-breaking telescopic cylinder 152 through an external pipe. By inflating and expanding, it pushes the sensing cavity 321 outward, causing the sensing cavity 321 to push the conductor coil 101 and tighten it, thereby changing the tightness of the conductor coil 101 and compensating for the tension when it is wound around a part of the electronic component with a small diameter.

[0042] The sensing cavity 321 is equipped with a sensor 330, which is used to sense the pressure inside the sensing cavity 321 and indirectly reflect the real-time tension of the coil 101 during the winding process. The sensed tension data is then transmitted to the external control system, which controls the expansion of the pressure regulating cavity 322 to dynamically balance the tension of the coil 101.

[0043] This application divides the adjustment block 320 into a sensing cavity 321 and a pressure regulating cavity 322. The former senses the tension, while the latter pushes the coil to tighten. The sensing cavity 321 indirectly measures the tension through changes in air pressure, avoiding physical interference to the wire. The sensor 330 detects the air pressure in the sensing cavity 321, calculates the real-time tension, and controls the expansion of the pressure regulating cavity 322, so that the tension can be automatically increased when winding the fine end of the electronic component, eliminating interlayer gaps and improving winding uniformity.

[0044] The synergistic action of the clamping airbag 230, airbag cavity 231, regulating air pump 240, sensing cavity 321, pressure regulating cavity 322, and wire-breaking telescopic cylinder 152, together control the real-time winding trajectory deviation correction of the conductor coil 101, satisfies the following relationship: Coaxiality correction satisfies the following relationship:

[0045] in, This refers to the amount of pressure change that needs to be adjusted in cavity 231; Real-time pressure detected by sensor 250; The coaxial reference pressure is preset based on the diameter of the electronic component. The feedback gain coefficient of the control system (dimensionless) is determined by system calibration, and its typical value range is [value range missing]. ; Tension compensation satisfies the following relationship:

[0046] in, The inflation volume of the pressure regulating chamber 322; The real-time tension is inferred by sensor 330 based on the pressure change inside sensing cavity 321; The preset ideal tension value; The proportional coefficient of the tension compensation system is determined by the structural geometry of the pressure regulating cavity 322 (such as the elastic modulus of the bladder and the effective cross-sectional area), and its value range is [value missing]. .

[0047] A laser sensor can be fixed to the side of the fixed block 300 near the electronic component to scan the outline of the electronic component in real time, i.e. its external dimensions, predict the position of the diameter change (such as the transition area from the thick end to the thin end of a cone), and adjust the pressure of the pressure regulating cavity 322 in advance based on the outline data (such as pressurizing the thin end area in advance) to offset the transmission delay and improve the control efficiency.

[0048] The sensor 250 is used to detect the local pressure distribution of the clamping airbag 230. It is a thin-film piezoresistive pressure sensor, preferably a Tekscan FlexiForce A201 or PPS 3315 array sensor. The sensor 330 is used to sense the gas pressure in the sensing cavity 321 (indirectly reflecting the tension). It is a piezoresistive pressure sensor, preferably a Honeywell MLH series sensor. The external control system is used to receive the pressure information from the sensor 250 and the sensor 330 and send commands to the regulating air pump 240 and the disconnected telescopic cylinder 152 in the actuator to control the inflation and deflation of air. It is preferably a Siemens S7 to 1200 series PLC. All of these are existing technologies and will not be described in detail here.

[0049] In addition, the coil guide block 131, lead screw 132, coil guide rod 133, coil guide groove 134, rotating winding mechanism 120, coil guide mechanism 130, and electronic component pick-and-place mechanism 140 in this application are all referenced from an electronic component winding device in patent number CN119181590B, which are prior art. Their specific structures and working principles have been described in detail in the cited patent, so this application will not elaborate further.

[0050] The control process for real-time correction of winding trajectory deviation during the winding of electronic components in this application is as follows: (1) When the electronic components tilt due to tension during the winding process, causing abnormal local pressure in the clamping airbag 230, the coaxiality correction process for the electronic components is as follows: When the electronic components tilt due to tension during the winding process, causing abnormal local pressure in the clamping airbag 230, the sensor 250 detects an imbalance in the pressure distribution of the airbag 231, and it is urgent to restore the coaxial state of the components by independently adjusting the pressure of multiple airbags 231. Pressure 231 was detected in the left cystic cavity. ; Right cystic cavity pressure 231 ; Pressure deviation: ; ; At this point, the component tilt causes the winding trajectory to deviate from the theoretical center. ; Among them, when electronic components (such as hourglass-shaped magnetic cores) are wound, due to the tension of the coil... When tilting occurs, its axis forms an angle with the theoretical centerline. In this regulatory process, with The value should be taken as 15°. At this moment, the horizontal component force That is, to push the component to move laterally; vertical component That is, to maintain the winding motion; The clamping reaction force is unbalanced, and the pressure distribution in the cavity 231 of the clamping airbag 230 is uneven and cannot be completely offset. This causes the centroid of the component to shift; offset By angle of inclination Determined by component size: ; in, The length of the component can take any value; the value chosen here is... For example; Right now ; The external control system calculates the pressure regulation amount in cavity 231: ; ; Control the regulating air pump 240 at the corresponding position to depressurize the left sac cavity 231 by pumping air out. ; The right sac cavity 231 was inflated and pressurized to ; By using gradient hardness silicone to clamp the airbag 230 in an adaptive deformation manner, the component is pushed back to the center, thereby reducing the coaxiality deviation and restoring the winding trajectory to a concentric circle.

[0051] (2) such as Figure 7 and Figure 8 As shown, when the conductor coil 101 is wound to the tapered end of the electronic component (i.e., the diameter decreases), and the conductor coil 101 is in a relaxed state, the tension compensation process for the conductor coil 101 is as follows: The preset reference tension corresponds to the air pressure as follows: ; At this moment, sensor 2 330 detects that the air pressure in sensing cavity 321 drops to ; Real-time tension ; in The calibration coefficient is the air pressure of the sensing cavity 321. Tension of conductor coil 101 The conversion factor is determined by the structural parameters and material properties, and its value is [value missing]. ; Target tension ; The control system calculates the tension deviation: ; The required inflation volume for conversion to pressure regulating chamber 322: ; in, Here, represents the system gain, and represents the tension deviation. to inflation volume The conversion gain, in its physical essence, is the mechanical efficiency parameter of the pressure regulating chamber 322, which is determined by the structural geometry and takes a value of 0.5. At this time, the wire-breaking telescopic cylinder 152 injects into the pressure regulating chamber 322. The gas pressure regulating chamber 322 expands, pushing the sensing chamber 321 outward, tightening the coil 101, and restoring the coil tension to its original state. This achieves tension balance.

[0052] The above-mentioned control process adopts a dual-system linkage of coaxiality correction and tension compensation synergy. When the winding reaches the waist of the hourglass element, coaxiality deviation and tension drop are triggered simultaneously. At this time, the clamping system responds first, sensor 250 detects pressure imbalance, and adjusts air pump 240 to correct coaxiality. Then, the tension system compensates with lag. After the coaxiality is restored, sensor 330 detects insufficient tension, and pressure regulating chamber 322 is inflated to correct the winding trajectory. Through the synergy of the dual systems, the trajectory deviation is controlled within ±0.1 mm.

[0053] In actual operation, the steps of this embodiment are as follows: First, the electronic component picking and placing mechanism 140 is activated to grab the horizontally placed electronic component and position it between the clamping components 200. The clamping telescopic cylinder 210 is activated to push the connecting plate 220 and the clamping airbag 230 against both ends of the electronic component. The air pump 240 is adjusted to inflate the corresponding airbag 231 to achieve uniform fit. At the same time, the sensor 250 detects the pressure in real time to support coaxiality correction. Next, the rotating winding mechanism 120 is activated to drive the guide coil 101 to move circumferentially for winding. The guide coil 101 is led out through the coil guide groove 134, and the lead screw 132 drives the coil guide block 131 to move laterally. During the winding process, the sensor 250... 50 Real-time detection of clamping pressure distribution, prediction of coaxiality deviation, and cooperation with external control system to achieve real-time coaxiality correction; When the winding reaches the tapered end of the electronic component (i.e., the diameter becomes smaller), the coil tension decreases due to relaxation, resulting in micro-gaps between winding layers. At this time, the sensing cavity 321 contacts the conductor coil 101 and senses the real-time tension through changes in internal gas pressure. The sensor 330 transmits the tension data to the control system, which inflates the pressure regulating cavity 322, pushing the sensing cavity 321 outward to tighten the conductor coil 101 and achieve dynamic tension balance; Finally, after winding is completed, the wire-cutting telescopic cylinder 152 pushes the moving clamping block 153 to cooperate with the fixed clamping block 310 to cut the conductor coil 101.

[0054] The coordinated control process of real-time coaxiality correction and winding trajectory correction: If the winding tension causes the electronic component to tilt, the sensor 250 detects the abnormal local pressure of the clamping airbag 230 and feeds it back to the control system. The control system commands the air pump 240 to inflate / de-inflate the specific bladder 231, pushing the component to restore coaxiality; The linkage process of real-time coaxiality correction and tension system: Coaxiality correction (i.e., clamping airbag 230) and tension compensation (i.e., adjustment block 320) work together to correct the winding trajectory deviation, ensuring that the winding trajectory is a theoretical concentric circle.

[0055] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: It effectively solves the technical problems of insufficient adaptability, uneven clamping force of curved electronic components, large coaxiality deviation during the winding process, coil tension fluctuation, uneven winding and reduced quality in the existing technology, and achieves the technical effects of improved adaptability, uniform clamping of curved components, significant reduction of coaxiality deviation, dynamic balance of coil tension, and simultaneous improvement of winding uniformity and quality.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
