Description

Technical Field

[0001] This utility model relates to the field of motor coil winding technology, and in particular to a motor coil winding device. Background Technology

[0002] Motor coil winding is the process of winding enameled wire (or other insulated wire) around the grooves of the motor core or a winding mold according to specific rules and parameters to form the "heart" of the motor—the electromagnetic coil. Motor coil winding is a core part of motor manufacturing and maintenance, and its quality directly affects the efficiency, lifespan and safety of the motor. The working principle of the motor is based on electromagnetic induction, and the coil is the core of generating the magnetic field.

[0003] Chinese Patent Publication No. CN222366172U relates to the field of motor accessories technology, and in particular to a motor coil winding device, including a frame, a winding mechanism, and a winding coil. The winding mechanism is located inside the frame, and the winding coil is located on the winding mechanism. A cutting component is located on the right side of the frame, and the cutting component is used to cut the wires on the winding coil. The cutting component includes a connecting component. By setting the cutting component, the wires on the coil can be cut quickly, thereby reducing the workload of the workers and improving the efficiency of the entire winding process.

[0004] For existing motor coil winding devices, in actual use, the material wire is prone to imbalance and looseness. This results in the material wire not being taut during the coil winding process, causing the coil to fail to form. However, if it is fully taut, the material wire is prone to breakage, affecting the winding. It is impossible to apply appropriate force to the material wire to make it taut and prevent it from breaking. It is also inconvenient to reset during cutting, affecting subsequent material wire cutting. Utility Model Content

[0005] The purpose of this invention is to provide a motor coil winding device that solves the problem in the prior art of not being able to apply appropriate force to the material wire to make the material wire taut and not break.

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

[0007] A motor coil winding device includes a fixed plate and a winder. A lead wheel is rotatably connected to the surface of the fixed plate, and a mounting shaft is fixedly connected to the surface of the fixed plate. An adjusting rod is provided on the surface of the mounting shaft, and an adjusting wheel is rotatably connected to one end of the adjusting rod. An adjusting groove is formed on the surface of the adjusting rod. The mounting shaft and the adjusting groove are rotatably connected via a torsion spring shaft. A guide block is fixedly connected to the surface of the fixed plate, and a guide groove is formed inside the guide block. Several tensioning wheels are rotatably connected to the surface of the fixed plate.

[0008] Preferably, the surface of the fixing plate is provided with an installation groove, a cutting block is fixedly connected to the surface of the installation groove, and a cutting blade is rotatably connected between the top of the cutting block and the top of the installation groove.

[0009] Preferably, a motor is fixedly connected to the back of the fixing plate, and a drive gear is driven by the output shaft of the motor. A force-bearing gear is fixedly connected to the top of the cutting blade, and the force-bearing gear meshes with the drive gear.

[0010] Preferably, an insertion rod is fixedly connected to the surface of the fixing plate.

[0011] Preferably, several tensioning rollers are located on both sides above the insertion rod.

[0012] Preferably, the surface of the lead-out wheel is provided with an anti-detachment groove, and two anti-detachment rings are fixedly connected inside the anti-detachment groove.

[0013] This utility model has the following beneficial effects:

[0014] Before winding the coil, the material wire needs to be straightened by the tensioning wheel to prevent it from completely affecting the subsequent winding. A counterclockwise spring force is applied to the adjusting rod through the torsion spring shaft, so that the adjusting wheel always compresses the material wire, thus ensuring the wire is taut. When the material wire is under excessive tension, the adjusting wheel is squeezed and rotated to relieve the pressure on the material wire and prevent it from breaking easily. This protects the material wire from breaking and affecting its use when it is straightened. When it is necessary to cut the material wire after winding, the cutting blade can be easily rotated by the motor, so that the cutting end can return to its original position after cutting the material wire for the next use.

[0022] 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.

[0023] Reference Figure 1-5A motor coil winding device includes a fixed plate 1 and a winder 2. The winder 2 is a mature existing technology used for winding to form a coil. A lead-out wheel 3 is rotatably connected to the surface of the fixed plate 1. When winding is required, the material wire is first placed onto the fixed plate 1 through a material wire roller, and then pulled out so that the material wire passes through the lead-out wheel 3 and enters the winder 2 for winding. During this process, the lead-out wheel 3 can restrict the material wire to ensure that the movement trajectory of the material wire does not change and affect the tension of the material wire. The tensioned material wire is wound in the winder 2. A mounting shaft 4 is fixedly connected to the surface of the fixed plate 1. The surface of the mounting shaft 4 is equipped with an adjusting rod 5, one end of which is rotatably connected to an adjusting wheel 6. An adjusting groove 7 is formed on the surface of the adjusting rod 5. The mounting shaft 4 and the adjusting groove 7 are rotatably connected via a torsion spring shaft 8. Before the wire enters the output wheel 3, it needs to pass through the adjusting wheel 6 for tensioning and straightening. During this process, the material wire passes through the adjusting wheel 6, and the position of the adjusting wheel 6 is determined by the adjusting groove 7 on the adjusting rod 5. The adjusting rod 5 rotates via the mounting shaft 4, and the torsion spring shaft 8 between the mounting shaft 4 and the adjusting groove 7 ensures that the adjusting rod 5 has a counterclockwise rotational force. As the material wire moves on the adjusting wheel, the adjusting wheel... The spring force of the torsion spring shaft 8 compresses the material thread, ensuring its tension and facilitating subsequent winding. When faced with different materials and conditions, the spring force of the torsion spring shaft 8 keeps the adjusting wheel constantly compressing the material thread, adapting to varying thread conditions. This ensures the material thread enters the output wheel 3 taut, preventing slack. The spring force of the torsion spring shaft 8 is not excessive, preventing the material thread from breaking. The material thread is tensioned while ensuring its safety. A guide block 9 is fixedly connected to the surface of the fixing plate 1, and a guide groove 10 is formed inside the guide block 9. When the material thread enters the adjusting wheel 6... Before tensioning, the material wire can pass through the guide block 9 via the guide groove 10. The guide groove 10 is a horizontal straight line. After the material wire enters the guide groove 10, it can be straightened by the guide groove 10, which facilitates the use of the material wire later. Several tensioning rollers 11 are rotatably connected to the surface of the fixing plate 1. After the material wire leaves the material roller, it can enter the surface of several tensioning rollers 11. The material is tensioned and straightened by several tensioning rollers 11 to prevent the material wire from bending and entering the winding machine 2. It can ensure that the material wire enters the winding machine 2 under tension and without twisting to wind the coil of the motor 15.

[0024] Furthermore, the surface of the fixing plate 1 is provided with a mounting groove 12, and a cutting block 13 is fixedly connected to the surface of the mounting groove 12. A cutting blade 14 is rotatably connected between the top of the cutting block 13 and the top of the mounting groove 12. When the winding of the coil of a motor 15 is finished, the material wire can be cut by the cutting blade 14 in conjunction with the cutting block 13, and then the winding of the next coil can be carried out. The cutting block 13 and the cutting blade 14 are both located below the wire output wheel 3, which facilitates the cutting of the subsequent material wire for winding. The mounting groove 12 facilitates the circular motion of the cutting blade 14 to cut the material wire. The elliptical space between the cutting block 13 and the cutting blade 14 facilitates the material wire to pass through for winding, preventing the material wire from detaching from the cutting blade 14 during the winding process, which would make subsequent material wire cutting inconvenient.

[0025] Furthermore, a motor 15 is fixedly connected to the back of the fixing plate 1. The output shaft of the motor 15 is driven by a drive gear 16. A force-receiving gear 17 is fixedly connected to the top of the cutting blade 14. The force-receiving gear 17 meshes with the drive gear 16. When the material line needs to be cut, the motor 15 can be started. The output shaft of the motor 15 rotates, driving the drive gear 16 to rotate. The drive gear 16 can drive the force-receiving gear 17, which meshes with it, to rotate. Since the force-receiving gear 17 is fixedly connected to the cutting blade 14, the motor 15 can drive the cutting blade 14 to rotate after starting. This, in conjunction with the cutting block 13, cuts the material line. After cutting, the motor 15 continues to rotate until it rotates 360°, causing the cutting blade 14 to return to its original position. This allows for easy reset of the cutting blade 14, facilitating the next cutting of the material line and enabling convenient reuse.

[0026] Furthermore, an insertion rod 18 is fixedly connected to the surface of the fixing plate 1. Before the material line on the material roller needs to be pulled out for use, the groove in the middle of the material roller needs to be inserted by the insertion rod 18, so that the material roller can roll to discharge material.

[0027] Furthermore, several tensioning wheels 11 are located on both sides above the insertion rod 18. The cooperation of multiple tensioning wheels 11 can straighten and tension the bent or twisted material wire, thereby facilitating the material wire to enter the subsequent tensioning structure for processing, so that the material wire entering the winding device 2 meets the usage requirements.

[0028] Furthermore, the surface of the lead wheel 3 is provided with an anti-detachment groove 19, and two anti-detachment rings 20 are fixedly connected inside the anti-detachment groove 19. The cooperation between the anti-detachment groove 19 and the anti-detachment rings 20 can restrict the material wire inside the lead wheel 3 when the wire is being led out, preventing the material wire from detaching from the lead wheel 3 and affecting the use of the winder 2.

[0029] In summary:

[0030] When winding the coil, the material roller is first placed onto the insertion rod 18, and then the material wire on the material roller is placed between several tensioning rollers 11. The tensioning rollers 11 straighten and tension the material wire. After the material wire leaves the tensioning rollers 11, it enters the guide groove 10 in the guide block 9 and is straightened inside the guide groove 10. After passing through the guide groove 10, the material wire enters the adjusting roller 6. The adjusting roller 6 is controlled by the adjusting rod 5. The adjusting groove 7 on the adjusting rod 5 has a counterclockwise elastic force through the mounting shaft 4 and the torsion spring shaft 8, which allows the adjusting roller 6 to tighten the material wire. Then the material wire enters the output roller 3 and is restricted by the anti-detachment groove 19 and anti-detachment ring 20 on the output roller 3, preventing it from easily detaching from the output roller. Then the material wire enters the winder 2. During winding, the material wire is straightened to prevent bending at the output, allowing for normal winding. After winding is completed, the motor 15 can be started. The drive on the motor 15... Gear 16 drives the force-bearing gear 17 on the cutting blade 14 to rotate, allowing the cutting blade 14 to rotate inside the mounting groove 12. This, in conjunction with the cutting block 13, cuts the finished winding material wire. After cutting, the cutting blade 14 returns to its original position as it continues to wind, facilitating the next material wire cutting and coil winding. Through this structure, the spring force of the torsion spring shaft 8 causes the adjusting wheel 6 to rotate counterclockwise. When the material wire is straightened and taut, it applies force to the adjusting wheel 6. The adjusting wheel 6 is adjusted by the spring force of the torsion spring shaft 8, ensuring that the material wire is not broken while being straightened. This allows the material wire to enter the winding machine 2 without loosening, ensuring the quality of the coil winding. At the end of winding, the motor 15 drives the cutting blade 14 to cut the material wire in conjunction with the cutting block 13. The cutting blade 14 can easily reset, ensuring cutting stability and facilitating the next cut, making subsequent use convenient.
