Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically an automatic winding machine adapted to various specifications of audio coils. Background Technology

[0002] A winding machine is a device used to wind wires onto specific workpieces. It is widely used for winding various wires such as copper wire, aluminum wire, and textile wire. The wires are wound on the winding machine according to specific rules onto insulating materials or other substrates to form the required coils or windings. This also includes the winding operation of audio coil components.

[0003] Utility model patent CN202555728U discloses an adjustable winding device for a winding machine. This device allows a robotic arm to adapt to metal supports of different sizes with semi-circular cross-sections, providing flexibility and versatility. Driven by a drive unit, the robotic arm moves along the outer edge of the winding mold on which the metal support is mounted, winding the metal wire onto the mold, thus achieving automated operation.

[0004] However, the above-mentioned adjustable winding device still has the following problems in actual use: Although the winding operation is achieved by the movement of the robot arm in conjunction with the winding device, this type of winding device only changes the winding range of the wire group. After winding, the winding diameter is not changed. Similarly, the device cannot be adapted to different specifications of winding drums for installation. As a result, it is necessary to replace the positioning mechanism with a different diameter during the winding process, which affects the winding efficiency.

[0005] Therefore, we propose an automatic winding machine that is compatible with various specifications of audio coils in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an automatic winding machine that is compatible with various specifications of audio coils. This addresses the problem that existing winding machines use a robotic arm to move in conjunction with a winding device to perform winding operations. However, such winding devices only change the winding range of the coil and do not change the winding diameter after winding. Similarly, this device cannot be adapted to different specifications of winding drums for installation. Consequently, different diameter positioning mechanisms need to be replaced during the winding process, which affects winding efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding machine adaptable to multi-specification audio coils, comprising a support base and positioning bases fixedly installed on the left and right sides of the top surface of the support base, wherein a drive motor is fixedly installed on the left end of the support base; further comprising:

[0008] The top surface of the support base is provided with a winding mechanism on both the left and right sides, and the winding mechanism includes a positioning turntable, and a positioning locking block is slidably provided inside the positioning turntable at equal angles.

[0009] The lower interior of the support base is provided with a wire guide mechanism, which includes a wire guide bracket and a wire guide moving ring on the inner side of the wire guide bracket.

[0010] Preferably, the winding mechanism includes a drive shaft, and the outer end of the drive shaft is rotatably disposed inside the left and right positioning bases via bearings, and the left end of the drive shaft is fixedly connected to the output shaft end of the drive motor.

[0011] Preferably, the winding mechanism includes positioning turntables fixedly installed at the left and right ends of the drive shaft, and the symmetrically arranged positioning turntables are equipped with guide slide rods at equal angles inside, and the guide slide rods slide through the interior of the positioning locking block.

[0012] Preferably, the winding mechanism includes an unlocking ring, which is rotatably disposed inside the left and right positioning turntables by a torsion spring. The inner side of the unlocking ring is fixedly connected to the outer end of the traction cable at equal angles, and the inner end of the traction cable, which is also fixedly connected to the outer end of the correspondingly distributed positioning locking blocks.

[0013] Preferably, the positioning locking block included in the winding mechanism is connected to the inner end of the guide slide rod by a reset spring, and the inner end of the positioning locking block in the initial state is close to the center position of the positioning turntable. The positioning locking blocks set at equal angles are used to position and lock the coil winding drum.

[0014] Preferably, the wire guide mechanism includes a reciprocating threaded rod, and the outer end of the reciprocating threaded rod is rotatably disposed on the lower inner side of the left and right wire guide supports via a bearing. The reciprocating threaded rod is threaded through the interior of the wire guide slider, and a positioning slide rod is slidably disposed at the top end of the wire guide slider.

[0015] Preferably, the positioning slide rod included in the wire guide mechanism is fixedly installed on the lower inner side of the left and right wire guide brackets, and the outer side of the reciprocating threaded rod included in the wire guide mechanism is engaged with the outer wall of the drive shaft through a pulley assembly, and the wire slider included in the wire guide mechanism is fixedly connected to the wire moving ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic winding machine, which is compatible with multi-specification audio coils, uses symmetrically distributed positioning turntables and internally slidingly installed positioning locking blocks to lock and position coil drums of different specifications. This allows for the installation of coil drums of different specifications. At the same time, the reciprocating moving wire ring pulls the cable for winding, preventing the cable from continuously winding and accumulating. The specific details are as follows:

[0017] 1. Rotating the unlocking mechanism causes the traction cable fixed on the inner side to move and stretch. Then, the traction cable causes the positioning locking block fixed on the inner end to slide outward along the direction of the guide slide rod, thereby increasing the distance between the positioning locking block set at the same angle and the center of the positioning turntable, so as to adapt to the installation of coil drums of different specifications.

[0018] The positioning locking block is driven by the return spring to slide inward synchronously, so that it abuts against the outer end of the coil tube, so that the coil tube can be positioned and locked. At the same time, the drive motor drives the drive shaft inside the positioning base to rotate. The drive shaft drives the fixedly connected positioning turntable and the inner coil tube to rotate synchronously to assist the cable winding.

[0019] 2. The drive shaft rotates the reciprocating threaded rod via the pulley assembly. The wire slider is limited by the sliding through positioning rod, so that the rotating reciprocating threaded rod drives the wire slider and the wire moving ring to move back and forth in the left and right directions, thereby guiding the cable through and winding it, and avoiding the continuous winding and accumulation of the coil cable, which affects the effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: To address the problems existing in the use of current coil winding machines, this example provides an automatic winding machine adaptable to various specifications of audio coils. The machine includes a support base 1 and positioning bases 2 fixedly installed on the left and right sides of the top surface of the support base 1. A drive motor 3 is fixedly installed on the left end of the support base 1. Winding mechanisms are provided on both the left and right sides of the top surface of the support base 1, and each winding mechanism includes a positioning turntable 4. Positioning locking blocks 5 are slidably arranged at equal angles inside the positioning turntable 4. The winding mechanism includes a drive shaft 8, and the outer end of the drive shaft 8 is rotatably mounted inside the positioning bases 2 on both sides via bearings. The left end of the drive shaft 8 is fixedly connected to the output shaft end of the drive motor 3.

[0030] The winding mechanism includes a positioning turntable 4 fixedly installed at the left and right ends of the drive shaft 8. Guide slide rods 9 are fixedly installed at equal angles inside the symmetrically arranged positioning turntables 4, and the guide slide rods 9 slide through the interior of the positioning locking block 5. The winding mechanism includes an unlocking ring 10, which is rotatably arranged inside the left and right positioning turntables 4 via a torsion spring. The inner side of the unlocking ring 10 is fixedly connected at equal angles to the outer end of the traction cable 11, and the inner end of the traction cable 11, which is also fixedly connected at equal angles, is fixedly connected to the outer end of the correspondingly distributed positioning locking blocks 5. The positioning locking blocks 5 and the inner ends of the guide slide rods 9 in the winding mechanism are connected to each other via a return spring 12. In the initial state, the inner end of the positioning locking block 5 is close to the center of the positioning turntable 4, and the positioning locking blocks 5, which are also set at equal angles, are used to position and lock the coil winding drum.

[0031] like Figures 3-5 As shown, when it is necessary to fix and install coil drums of different specifications, the unlocking ring 10 set inside the positioning turntable 4 is manually rotated, causing the traction steel cable 11 fixedly connected to the inner side to move and stretch. Then the traction steel cable 11 drives the positioning locking block 5 fixedly connected to the inner end to slide outward along the direction of the guide slide rod 9, thereby increasing the distance between the positioning locking block 5 set at the same angle and the middle of the positioning turntable 4, so as to adapt to the installation of coil drums of different specifications.

[0032] Furthermore, by placing the coil tube in the middle of the inner side of the left and right positioning turntables 4, and then driving the connected positioning locking block 5 to slide inward synchronously through the return spring 12 inside the guide slide rod 9, the positioning locking block 5 abuts against the outer end of the coil tube, so that the coil tube is positioned and locked, preventing it from loosening and falling off during subsequent rotation. At the same time, the drive motor 3 drives the drive shaft 8 inside the positioning base 2 to rotate, and the drive shaft 8 drives the fixedly connected positioning turntable 4 and the coil tube inside it to rotate synchronously to assist the cable winding.

[0033] Example 2: In order to solve the problems existing in the use of the existing coil winding machine, this example adopts the following technical solution: a wire mechanism is provided inside the lower part of the support base 1, and the wire mechanism includes a wire support 6, and a wire moving ring 7 is provided on the inner side of the wire support 6; the wire mechanism includes a reciprocating threaded rod 13, and the outer end of the reciprocating threaded rod 13 is rotatably set on the lower inner side of the left and right wire supports 6 through a bearing, and the reciprocating threaded rod 13 is threaded through the inside of the wire slider 14, and a positioning slide rod 15 is slidably provided at the top of the wire slider 14.

[0034] The positioning slide rod 15 included in the wire guide mechanism is fixedly installed on the lower inner side of the left and right wire guide brackets 6, and the outer side of the reciprocating threaded rod 13 included in the wire guide mechanism is engaged with the outer wall of the drive shaft 8 through the pulley assembly 16, and the wire slider 14 included in the wire guide mechanism is fixedly connected to the wire moving ring 7.

[0035] like Figure 1 , Figure 6 As shown, during the rotation of the drive shaft 8 inside the support base 1, it drives the reciprocating threaded rod 13 inside the bottom wire bracket 6 to rotate through the outer meshing pulley assembly 16. The wire slider 14, which is threadedly connected to the reciprocating threaded rod 13, is limited by the sliding through positioning slide rod 15, so that the rotating reciprocating threaded rod 13 drives the wire slider 14 and the wire moving ring 7 to move back and forth in the left and right directions, thereby guiding the cable through and winding it, avoiding the continuous winding and accumulation of the coil cable, which affects the effect.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
