Description

Technical Field

[0001] This utility model relates to the field of coil winding technology, specifically to a stranding mechanism and winding device. Background Technology

[0002] In the field of electronic component manufacturing, some coils (such as inductors and transformers) are typically wound with extremely fine copper wire due to their low-current operating requirements. However, under prolonged use or mechanical stress, the starting end of the coil (i.e., the lead-out portion) is prone to breakage, leading to electrical connection failure. The traditional solution is to wrap the wire around an auxiliary post at the starting section of the coil for reinforcement, but this method is cumbersome, inefficient, and prone to breakage due to uneven winding tension or during subsequent assembly.

[0003] To solve this problem, technicians manually twisted the two wires at the beginning of the coil into a twisted pair and then rewound them to improve the mechanical strength of the wire ends. Patent CN109920638A discloses a coil winding device, which includes clamps and a drive unit. During operation, the two clamps hold the winding seat together, connecting one end of the enameled wire to the winding seat. A PLC controller controls two servo motors to start at the same speed. Servo motor one drives the winding seat to rotate for the initial operation, while simultaneously, servo motor two drives the wire feeding seat to release the wire, achieving a simultaneous winding and releasing, thereby improving winding efficiency. This device can replace manual winding, saving time and labor, and improving winding efficiency.

[0004] However, the stranding of the starting section of the coil still requires manual stranding using tools. This stranding method is time-consuming and labor-intensive, significantly reducing production efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a stranding mechanism and winding device to solve the technical problem that in the prior art, the initial stranding work of coil winding requires manual use of tools to strand the coil, which is time-consuming and labor-intensive, and significantly reduces production efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

The connecting part is disposed at the wire inlet position of the winding mechanism and is equipped with a connecting end for connecting wires. The adjusting part is connected to the connecting part and is used to drive the connecting part to move closer to or away from the wires at the wire inlet position. The stranding drive part is connected to the connecting part and is used to drive the connecting end of the connecting part to rotate the stranded wire.

The slider is slidably connected to the guide rail. The connecting part is connected to the slider. The drive member is mounted on the guide rail and connected to the slider, and is used to drive the slider to slide along the guide rail, so as to drive the connecting part to move relative to the wire inlet position of the winding mechanism.

[0012] In some embodiments, the stranding mechanism further includes a fixing component, which includes two sets of clamping members. The two sets of clamping members are spaced apart at the wire inlet position of the winding mechanism for clamping the wire, and the connecting end of the connecting portion corresponds to the gap between the two sets of clamping members.

[0013] In some embodiments, the fixing component further includes a guide fixing member and two elastic reset members. The guide fixing member has two guide grooves on one side. The two sets of clamping members are respectively disposed in the two guide grooves and can slide relative to each other along the guide grooves. The two elastic reset members are respectively disposed in the two guide grooves and their two ends are respectively connected to the guide fixing member and the corresponding clamping members.

[0014] In some embodiments, the stranding mechanism further includes a varnish remover, the removal end of which is disposed on one side of the fixing assembly for removing insulating varnish from the surface of the wire.

[0015] In some embodiments, the stranding mechanism further includes a movable member connected to the fixed component, a movable end of the movable member connected to the paint stripper, and the movement path of the movable end being parallel to the straight line direction between the two clamping members.

[0016] Secondly, this utility model also provides a winding device, including the stranding mechanism and the winding mechanism as described in any one of the above.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the technical problem that the initial stranding process during coil winding requires manual use of tools, which is time-consuming, labor-intensive, and significantly reduces production efficiency, this invention provides a stranding mechanism and winding device that automates the stranding and winding process, reduces manual intervention, and greatly improves production efficiency.

[0030] Please see Figures 1 to 3 In a first aspect, embodiments of the present invention provide a stranding mechanism, including: a connecting part 11, an adjusting part 12, and a stranding drive part 13. The connecting part 11 is disposed at the wire inlet position of the winding mechanism 2 and is equipped with a connecting end for connecting wire 5. The adjusting part 12 is connected to the connecting part 11 and is used to drive the connecting part to approach or move away from the wire at the wire inlet position. The stranding drive part 13 is connected to the connecting part 11 and is used to drive the connecting end of the connecting part 11 to rotate the stranded wire.

[0031] In this device, the connecting part 11 is used to connect the wire 5 at the inlet position of the winding mechanism 2. The adjusting part 12 can drive the wire to drive the connecting part 11 to move relative to the inlet position of the winding mechanism 2, so that the connecting part 11 is closer to or farther away from the inlet position, so that the connecting end can connect the wire 5. Through the driving action of the adjusting part 12, the position of the connecting part 11 can be flexibly adjusted, which facilitates the connection and adjustment of the wire 5. At the same time, the flexible adjustment of the connecting part 11 allows the stranding mechanism 1 to move away from the inlet position when the coil is wound, without affecting the winding operation of the winding mechanism 2. The stranding drive part 13 can drive the connecting end of the connecting part 11 to rotate and strand the wire, so that the wire 5 can rotate as necessary during the connection process to achieve the stranding effect, thereby improving the winding quality and efficiency.

[0032] For easier connection of the threads, please refer to Figures 1 to 3 In this embodiment, the connecting part 11 has a channel for the wire to pass through. Its connecting end adopts a curved design, with the outer curved surface of the connecting end located on the side closer to the wire inlet position of the winding mechanism 2, and the inner concave surface of the connecting end located on the side opposite to the wire inlet position of the winding mechanism 2. When the connecting part 11 moves towards the wire, the curved design of the connecting end better guides the wire 5 smoothly into the concave area of ​​the connecting end. Furthermore, it can reduce wear on the wire 5 during the connection process to a certain extent, preventing damage to the wire 5. The concave surface design of the connecting end allows the wire 5 to fit more tightly against the connecting end during connection, enhancing the stability of the connection.

[0033] Please see Figures 1 to 3In one embodiment, the stranding mechanism 1 further includes a mounting plate 14, and the connecting part 11 includes a hook 111. The hook 111 forms a channel and an opening communicating with the channel, the opening being a channel for the wire to slide into. The stranding drive part 13 includes a first motor 131. Specifically, the hook portion of the hook 111 forms the connecting end of the connecting part 11. Therefore, the opening of the hook portion of the hook 111 is located away from the wire inlet position of the winding mechanism 2, and the direction of movement of the hook 111 relative to the wire inlet position of the winding mechanism 2 is consistent with the direction of its opening. This allows the wire to be guided to the opening by utilizing the outer curved surface of the hook 111 when the hook 111 moves toward the wire. Then, the adjusting part 12 drives the hook 111 to move in the opposite direction, tensioning the wire at the opening of the hook 111. This solution utilizes the hook 111 to hook the wire, achieving connection with the wire. The first motor 131 is fixedly installed on one side of the mounting plate 14, and the hook 111 is rotatably set on one side of the mounting plate 14 and connected to the drive end of the first motor 131, so that the hook 111 can be rotated by the driving action of the first motor 131, thereby driving the wire 5 to perform the twisting operation.

[0034] Of course, in other possible embodiments, the connecting part 11 can also adopt other different structural forms. For example, the connecting part 11 can be set as a clamping structure to connect and fix the wire 5 by clamping.

[0035] To adjust the position of hook 111, please refer to Figure 1 and Figure 3 In some possible embodiments, the adjustment unit 12 includes a guide rail 121, a slider 122, and a drive member 123. Specifically, the guide rail 121 is disposed on one side of the wire inlet position of the winding mechanism 2 and perpendicular to the wire introduced on the wire guide mechanism 3. It has a guide groove inside, the slider 122 is disposed in the guide groove and can slide in the guide groove, the mounting plate 14 is fixed on the top surface of the slider 122, and the drive member 123 is installed in the guide groove of the guide rail 121. It connects the slider 122 and the groove wall of the guide groove and can drive the slider 122 to slide in the guide groove. When the slider 122 slides, it can drive the mounting plate 14 and the hook 111 to move relative to the wire inlet position of the winding mechanism 2.

[0036] For more precise control of the movement of slider 122, please refer to [link / reference]. Figure 3In this design, the drive component 123 can be a motor or a lead screw assembly. The motor is fixedly mounted at one end of the guide rail 121, and its drive end is connected to one end of the lead screw assembly. The other end of the lead screw assembly is rotatably mounted at the other end of the guide rail 121. The lead screw portion of the lead screw assembly passes through the slider 122 and is threadedly connected to the slider 122. Driven by the motor, the lead screw assembly rotates, thereby driving the slider 122 to slide within the guide groove. Of course, the drive component 123 is not limited to a motor; it can also be a cylinder, hydraulic cylinder, or other drive devices capable of providing linear reciprocating motion.

[0037] Furthermore, to improve the quality of the stranded wire, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 4 and Figure 5 In some possible embodiments, the stranding mechanism 1 further includes a fixing component 15, which is disposed opposite to the connecting portion 11. The fixing component 15 includes two sets of clamping fasteners 151, a guide fixing member 152, and two elastic reset members 153. Specifically, the two sets of clamping fasteners 151 are spaced apart at the wire inlet position of the winding mechanism 2 to effectively clamp and fix the wire 5. The position of the hook 111 corresponds to the gap between the two sets of clamping fasteners 151. By fixing the clamping fasteners 151, the hook 111 can easily hook the fixed wire, preventing the wire 5 from shaking or shifting when it contacts the hook 111. In order to enable smooth and stable stranding, two guide grooves 1521 are provided on one side of the guide fixing member 152. The two guide grooves 1521 provide a sliding path for the two sets of clamping fasteners 151. The clamping member 151 can move flexibly relative to the guide groove 1521. Two elastic reset members 153 are respectively disposed in the two guide grooves 1521, and their two ends are respectively connected to the guide fixing member 152 and the corresponding clamping member 151.

[0038] During the twisting operation, after the hook 111 moves between the two sets of clamps 151 and hooks the wire, the adjusting part 12 can be used to drive the hook 111 to move away from the fixing parts. At this time, the hook 111 pulls the wire, which can cause the two sets of fixing blocks to gradually slide closer. Subsequently, the twisting drive part 13 starts to work, driving the hook 111 to rotate the wire to wind the twisted pair. After the twisting is completed, the clamps 151 can be released. At this time, the clamps 151 can be reset by the action of the elastic reset part 153 to allow for the next round of twisting operation.

[0039] Preferably, please refer to Figure 4 and Figure 5In this embodiment, the clamping component 151 adopts an electric clamping structure. The jaws of the clamp are designed with wire fixing holes, through which the wire 5 can be clamped between the jaws. During the twisting process, the two sets of clamping components 151 work together to fix the wire 5 at the wire inlet position of the winding mechanism 2, making the twisting operation more stable and reliable. The guide fixing component 152 adopts a guide fixing frame, and the guide fixing frame has a guide groove 1521 inside for the electric clamping structure to slide. The elastic reset component 153 is a spring, one end of which is fixed to the groove wall of the guide groove 1521, and the other end is connected to the electric clamping structure.

[0040] In the winding process, the insulating varnish (such as polyester or polyimide) on the surface of the enameled wire blocks current. The varnish layer at the wire end contact point must be removed to form a conductive path with the pads, leads, or other conductors. Therefore, before stranding, the wire 5 needs to be pre-treated to remove the insulating varnish from the wire end. To achieve this, in this embodiment, the stranding mechanism 1 further includes a varnish-removing component 16 and a moving component 17. The removal end of the varnish-removing component 16 is disposed on one side of the fixing assembly 15 and is used to remove the insulating varnish from the surface of the wire 5. The moving component 17 is connected to the fixing assembly 15, and its moving end is connected to the varnish-removing component 16. The moving path of the moving end is parallel to the straight line direction between the two clamping members 151. When stranding is required, after the clamping members 151 fix the wire 5, the moving component 17 drives the varnish-removing component 16 to move along the straight line direction between itself and the clamping members 151, allowing the removal end of the varnish-removing component 16 to reciprocate along the wire 5 to remove the insulating varnish from the surface of the wire 5.

[0041] Preferably, in this design, the paint stripping component 16 is a laser paint stripper, which utilizes the high-temperature characteristics of laser to quickly burn the insulating varnish on the surface of the wire 5, thereby achieving the purpose of paint removal. The removal end of the laser paint stripper is designed as a slender laser emission port, which can accurately aim at the surface of the wire 5, ensuring the accuracy and efficiency of the paint removal operation. The moving component 17 adopts an electric slide rail structure. One end of the electric slide rail is fixed on the guide frame, and the other end is connected to the laser paint stripper. Through the driving action of the electric slide rail, the laser paint stripper can be driven to move stably back and forth along the wire 5 to achieve a uniform paint removal effect.

[0042] Furthermore, to improve stranding efficiency, in this embodiment, the winding device also includes a controller and a time relay. The controller receives stranding commands, and the time relay controls the duration of the stranding operation. Specifically, before stranding begins, the operator can input stranding commands through the controller. Subsequently, the controller receives the commands and transmits signals to the time relay, the first motor 131 in the stranding mechanism 1, and the electric slide rail structure, etc. Upon receiving the signal, the time relay starts timing and controls the duration of the stranding operation to ensure the stability and accuracy of the stranding process. When the stranding operation reaches a preset time, the time relay sends a stop signal. The controller receives the stop signal and controls the first motor 131 and the electric slide rail structure, etc., to stop working, thereby ending the stranding operation.

[0043] Secondly, embodiments of this utility model also provide a winding device, including a stranding mechanism 1 and a winding mechanism 2 as described in any of the above embodiments. The winding mechanism 2 includes a second motor 21, a gear transmission assembly 22, and a chuck 23. The chuck 23 is used to fix the winding cylinder, and the second motor 21 drives the gear transmission assembly 22 to rotate the chuck 23 to wind the wire 5 onto the winding cylinder.

[0044] Furthermore, the winding device also includes a wire guide mechanism 3. The wire guide mechanism 3, the corner wire mechanism, and the winding mechanism 2 are all mounted on a mounting base 4. The wire guide mechanism 3 includes a wire block 31 and a wire drive structure 32. The wire block 31 is positioned on one side of the wire inlet position of the winding mechanism 2 to guide the wire 5 to be wound. The wire drive structure 32 is connected to the wire block 31 and can drive the wire block 31 to move, thereby adjusting the inlet position and direction of the wire 5. During the winding process, the wire guide mechanism 3 ensures that the wire 5 can be accurately guided into the winding mechanism 2, avoiding deviation or twisting of the wire 5, and improving the accuracy and efficiency of winding. The wire guide mechanism 3 employs a lead screw drive structure. One end of the lead screw drive structure is connected to the wire block 31, and the other end is connected to the winding mechanism 2. The lead screw drive structure includes a lead screw and a drive motor. The drive motor can drive the lead screw to rotate, thereby driving the wire block 31 to move linearly along the lead screw. By adjusting the rotation direction and speed of the drive motor, the moving position and direction of the conductor block 31 can be precisely controlled to adapt to wires 5 of different specifications and lengths.

[0045] This invention utilizes a designed stranding mechanism 1 and winding device. In the stranding mechanism 1, the connecting part 11 ensures a secure connection of the wire 5, and the adjusting part 12 drives flexible movement to adapt to different winding requirements. The stranding drive part 13 ensures that the connecting part 11 operates according to a predetermined rotation pattern, effectively stranding the wire 5 into a twisted pair and enhancing the mechanical strength of the wire ends. This device automates the stranding and winding process, reducing manual intervention and significantly improving production efficiency.
