Description

Technical Field

[0001] The present invention specifically relates to the technical field of winding equipment, and more specifically, to a winding equipment for optimizing the tightness of motor windings based on precise tension control. Background Art

[0002] The winding of a micro-motor is a key component of the motor. It is composed of many coils connected in a certain pattern. These coils are usually wound with insulated wires. The main function of the winding is to establish a magnetic field and induce electromotive force in the motor, thereby realizing the mutual conversion of electrical energy and mechanical energy; When manufacturing the winding, it is also necessary to strictly control the tightness of the wire during the winding process. An inappropriate tightness of the winding will cause changes in resistance and inductance. If the winding is too loose, the length of the wire may be slightly longer than the designed value. Since the resistance is proportional to the length of the wire, this will increase the resistance of the winding. For an AC motor, the inductance will also be affected. If the winding is too loose, the inductance may decrease, thereby changing the reactance of the motor and affecting the current and power factor of the motor.

[0003] However, in practice, it has been noted that after the wire is led out from the wire reel, a limiting structure is needed to guide the wire. Generally, a limiting hole is provided on the limiting structure. After passing the wire through the limiting hole, it is wound around the winding reel. When removing the wire, it is necessary to cut off the wire before it can be taken out from the positioning hole, and the cut wire cannot be used again, which is likely to cause waste of the wire. Summary of the Invention

[0004] The purpose of the present invention is to provide a winding equipment for optimizing the tightness of motor windings based on precise tension control. A locking structure that can be quickly switched is provided on the guiding structure of the wire, which is convenient for taking out the whole wire, saving the disassembly efficiency and ensuring the integrity of the wire at the same time. The removed wire can be used again, avoiding waste of materials. To solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A winding equipment for optimizing the tightness of motor windings based on precise tension control includes a winding machine main body. Symmetric telescopic rods are installed on the side of the winding machine main body. One end of the telescopic rod away from the winding machine main body is fixedly connected with a moving baffle, and the winding machine main body and the moving baffle are respectively provided with a winding rotating shaft and a rotating retaining ring; Wherein, the end of the winding rotating shaft is movably connected to the winding machine main body, and the rotating retaining ring is located at the other end of the winding rotating shaft. The rotating retaining ring is movably connected to the side of the moving baffle through a bearing; Above the winding rotation axis, there is also a U-shaped flipping frame. Both ends of the U-shaped flipping frame are provided with support arms. The U-shaped flipping frame is connected to the main body of the winding machine through the support arms. The side of the U-shaped flipping frame is fixedly connected with tightness adjusting seats in a rectangular array, and the tightness adjusting seats are arranged corresponding to the winding rotation axis.

[0006] As a further technical solution of the present invention, at both ends of the U-shaped flipping frame, there are also inclined shaft plates located on the other side of the support arms. A rotating shaft penetrating the end of the support arm is fixedly connected between the inclined shaft plate and the U-shaped flipping frame, and the side of the support arm is fixedly connected to the main body of the winding machine.

[0007] As a further technical solution of the present invention, on the side of each support arm away from the U-shaped flipping frame, there is a cylinder, and the end of the output rod of the cylinder is fixedly connected with a connecting shaft sleeve, and the connecting shaft sleeve is movably connected to the end of the inclined shaft plate.

[0008] As a further technical solution of the present invention, the tightness adjusting seat includes a fixing plate fixedly connected with a fixing plate. A support seat is integrally arranged on the side of the fixing plate, and a fastening baffle is covered at one end of the support seat away from the fixing plate. Among them, the support seat and the fastening baffle are movably connected through a pin shaft arranged on the side.

[0009] As a further technical solution of the present invention, a fixing lock plate is fixedly connected to the side of the support seat, and a U-shaped groove is opened inside the fixing lock plate, and a limiting baffle is integrally arranged on the side of the fixing lock plate away from the fastening baffle.

[0010] As a further technical solution of the present invention, an ear plate is integrally arranged on the side of the fastening baffle, and a rotating lock rod is movably connected inside the ear plate, and the end of the rotating lock rod is in snap-fit connection with the fixing lock plate. A guiding inclined rod is symmetrically penetrated in the support seat, and the guiding inclined rod is fixedly connected with the support seat.

[0011] As a further technical solution of the present invention, the rotating lock rod has a rotating shaft rod penetrating the ear plate. One end of the rotating shaft rod is fixedly connected with a ball head handle, and the ball head handle is located on the side of the ear plate; A blocking ring fixedly connected with the rotating shaft rod is arranged between the ball head handle and the ear plate, and a compression spring is arranged between the blocking ring and the ear plate.

[0012] As a further technical solution of the present invention, the end of the rotating shaft rod away from the ball head handle penetrates the fixing lock plate and is fixedly connected with a dislocation baffle, and the dislocation baffle and the ball head handle are staggered, and the dislocation baffle is snap-fitted on the side of the fixing lock plate away from the ear plate.

The wire passes through the tightness adjusting seat on the U-shaped turning frame. Therefore, when the U-shaped turning frame turns outward, the length of the wire to the wire roller will increase, thereby changing the tension of the entire wire. The tension during wire winding is controlled by the rotation angle of the U-shaped turning frame, eliminating the need for manual adjustment steps and reducing labor intensity. In the present invention, the fastening baffle is opened, the wire is placed in the symmetrically arranged wire grooves on the support seat, and then the fastening baffle and the support seat are quickly locked by the mutual cooperation of the rotating lock rod and the fixed lock plate, which is convenient for the overall removal of the wire from the tightness adjusting seat. Moreover, when disassembling, it is not necessary to cut off the wire, so that the removed wire can still be used normally, preventing waste of materials. In the present invention, the orientation of the misaligned baffle is controlled by the rotation of the rotating shaft rod, so that the misaligned baffle can be inserted through the opening of the fixed lock plate. Then, the rotating shaft rod is rotated by the ball head handle, and the misaligned baffle at the other end is rotated to the side of the fixed lock plate. The limiting baffle arranged on the side of the fixed lock plate blocks the misaligned baffle to prevent loosening of the connection. Description of the Drawings

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-11 , the embodiment of the present invention provides a winding device for optimizing the tightness of a motor winding based on precise tension control, including a winding machine main body 1. Symmetric telescopic rods 7 are installed on the side of the winding machine main body 1. One end of the telescopic rod 7 away from the winding machine main body 1 is fixedly connected with a moving baffle 8. The winding machine main body 1 and the moving baffle 8 are respectively provided with a winding rotary shaft 6 and a rotary retaining ring 9; Among them, the end of the winding rotary shaft 6 is movably connected to the winding machine main body 1, and the rotary retaining ring 9 is located at the other end of the winding rotary shaft 6. The rotary retaining ring 9 is movably connected to the side of the moving baffle 8 through a bearing; Above the winding rotating shaft 6, there is also a U-shaped turning frame 4. Both ends of the U-shaped turning frame 4 are provided with support arms 3. The U-shaped turning frame 4 is connected to the winding machine main body 1 through the support arms 3. The side of the U-shaped turning frame 4 is fixedly connected with tightness adjusting seats 5 in a rectangular array, and the tightness adjusting seats 5 are arranged corresponding to the winding rotating shaft 6.

[0029] In this embodiment, at both ends of the U-shaped turning frame 4, there are also inclined shaft plates 41 located on the other side of the support arms 3. A rotating shaft passing through the end of the support arm 3 is fixedly connected between the inclined shaft plates 41 and the U-shaped turning frame 4, and the side of the support arm 3 is fixedly connected to the winding machine main body 1.

[0030] Furthermore, on the side of each support arm 3 away from the U-shaped turning frame 4, there is a cylinder 31. The end of the output rod of the cylinder 31 is fixedly connected with a connecting shaft sleeve 32, and the connecting shaft sleeve 32 is movably connected to the end of the inclined shaft plate 41.

[0031] By adopting the above technical solution, the output rod of the cylinder 31 pushes the inclined shaft plate 41 to turn outward through the connecting shaft sleeve 32. The inclined shaft plate 41 drives the U-shaped turning frame 4 to turn outward. The wire passes through the tightness adjusting seats 5 on the U-shaped turning frame 4. Therefore, when the U-shaped turning frame 4 turns outward, it will increase the long distance of the wire to the wire roller, thereby changing the tension of the whole wire. The tension during wire winding is controlled by the rotation angle of the U-shaped turning frame 4, eliminating the manual adjustment step and reducing the labor intensity.

[0032] Furthermore, the tightness adjusting seat 5 includes a fixing plate 51 fixedly connected with a fixing plate 51. A support seat 52 is integrally provided on the side of the fixing plate 51. One end of the support seat 52 away from the fixing plate 51 is covered with a buckling baffle 54. Among them, the support seat 52 and the buckling baffle 54 are movably connected through a pin shaft arranged on the side.

[0033] Specifically, a fixing lock plate 57 is fixedly connected to the side of the support seat 52. A U-shaped groove is opened inside the fixing lock plate 57, and a limiting baffle 571 is integrally arranged on the side of the fixing lock plate 57 away from the buckling baffle 54.

[0034] Furthermore, an ear plate 55 is integrally provided on the side of the buckling baffle 54. A rotating lock rod 56 is movably connected inside the ear plate 55. The end of the rotating lock rod 56 is in clamping fit with the fixing lock plate 57. Guide inclined rods 53 are symmetrically penetrated through the support seat 52, and the guide inclined rods 53 are fixedly connected to the support seat 52.

[0035] Specifically, the rotating lock rod 56 has a rotating shaft rod 561 passing through the ear plate 55. One end of the rotating shaft rod 561 is fixedly connected with a ball head handle 562, and the ball head handle 562 is located on the side of the ear plate 55. Further, a blocking ring 563 fixedly connected with the rotating shaft rod 561 is arranged between the ball head handle 562 and the ear plate 55, and a compression spring 564 is arranged between the blocking ring 563 and the ear plate 55.

[0036] Further, the end of the rotating shaft rod 561 far from the ball head handle 562 passes through the fixed lock plate 57 and is fixedly connected with a misalignment baffle 565. The misalignment baffle 565 and the ball head handle 562 are staggered, and the misalignment baffle 565 is clamped on the side of the fixed lock plate 57 far from the ear plate 55.

[0037] By adopting the above technical solution, the orientation of the misalignment baffle 565 is controlled by the rotation of the rotating shaft rod 561, so that the misalignment baffle 565 can be inserted from the opening of the fixed lock plate 57. Then, the rotating shaft rod 56 is rotated by the ball head handle 562, and the misalignment baffle 565 at the other end is rotated to the side of the fixed lock plate 57. The limit baffle 571 arranged on the side of the fixed lock plate 57 blocks the misalignment baffle 565 to prevent the connection from loosening.

[0038] Further, wire grooves 58 are symmetrically arranged on the side of the support seat 52 close to the fastening baffle 54, and corresponding wire grooves 58 are also arranged on the side of the fastening baffle 54 close to the support seat 52.

[0039] By adopting the above technical solution, the fastening baffle 54 is opened, the wire is placed in the symmetrically arranged wire grooves 58 on the support seat 52, and then the fastening baffle 54 and the support seat are quickly locked by the mutual cooperation of the rotating lock rod 56 and the fixed lock plate 57, which is convenient for the overall removal of the wire from the tightness adjustment seat 5. And when disassembling, it is not necessary to cut off the wire, so that the removed wire can still be used normally, preventing waste of materials.

[0040] Further, a bearing is in interference fit with the end of the winding rotating shaft 6, and the winding rotating shaft 6 is rotationally connected with the winding machine main body 1 through the bearing. And a transmission sprocket is in interference fit with the end of the winding rotating shaft 6 located inside the winding machine main body 1. The ends of multiple winding rotating shafts 6 are connected by a transmission chain through sprocket transmission. Further, a driving motor is fixedly connected to the inside of the winding machine main body 1. A driving sprocket is in interference fit with the end of the driving motor, and the driving sprocket is in transmission connection with the transmission chain. The power is transmitted to each winding rotating shaft 6 through chain transmission, so that the driving motor drives the winding rotating shaft 6 to rotate.

[0041] Furthermore, one end of the winding rotating shaft 6 close to the rotating retaining ring 9 is symmetrically fixedly connected to the bobbin baffle 10, the coil seat is sleeved onto the end of the winding rotating shaft 6, and the raised position of the coil seat is clamped between the two coil baffles 10, so that the coil seat rotates with the rotation of the winding rotating shaft 6.

[0042] To be more specific, a lead bracket 2 is fixedly connected to the top of the winding machine body 1, and vertical rods corresponding to the tightness adjustment seat 5 are fixedly connected to the lead bracket 2 in a rectangular array, and each of the vertical rods is fixedly connected to a wire guide seat 11 on both sides. The wire passes around the side of the wire guide seat 11 on the vertical rod and then passes downward through the tightness adjustment seat 5.

[0043] The working principle of the present invention is as follows: when in use, firstly, the coil seat sleeve is connected to the end of the winding rotating shaft 6, and the protrusion on the side of the coil seat is clamped between the two coil baffles 10, and then the telescopic rod 7 drives the movable baffle 8 to move closer to the winding rotating shaft 6, until the rotating baffle ring 9 on the side of the movable baffle 8 fits with the end of the coil seat away from the winding rotating shaft 6, and then the wire is passed through the side of the wire guide seat 11 on the vertical rod and then downwardly penetrated through the tightness adjustment seat 5, and the wire is fixedly connected with the coil seat after passing through the tightness adjustment seat 5, and the driving motor in the winding machine body 1 drives the winding rotating shaft 6 to rotate through the chain drive, and the coil seat rotates with the winding rotating shaft 6, and the wire is wound around the coil seat, and when the output rod of the cylinder 31 is extended and retracted, the inclined shaft plate 41 is driven to rotate through the connecting shaft sleeve 32, thereby controlling the tightness adjustment seat 5 on the U-shaped flip frame 4 to swing, and controlling the tension of the wire during winding; When removing the wire, hold the ball handle 562 and press the rotating shaft 561 backward. The rotating shaft 561 drives the offset baffle 565 at the end to be offset from the limit baffle 571, and then the rotating shaft 561 drives the limit baffle 571 to rotate to a horizontal position, and finally move the rotating lock rod 56 forward. Since the snap-fit ​​baffle 54 is movably connected to the support seat 52 through the pin shaft, the snap-fit ​​baffle 54 is opened, and the wire located inside the wire groove 58 is completely taken out. There is no need to cut the wire, and the removed wire can be used again, thereby preventing waste.
