Through the synchronous electric control operation of the Z-axis slide rail, the Z-axis motor, the Y-axis slide rail, the Y-axis motor, the winding shaft, the wire management rod and the gear motor, the wire ends of each group of wires with different angles are wound on the wire management rod while winding the motor stator. The pressing block is driven down by the downward pressure electric cylinder to press down the enameled wire wound on the wire management rod, and the enameled wire wound on the wire management rod is pressed down and fitted to the incision groove of the fixing fixture for unified cutting, so that the wire groups of each angle are automatically cut and the wire ends are reserved at the same time after the winding is completed. When winding the stator of a brushless motor, because the material is usually copper wire, in cold areas, at lower temperatures, its molecular structure will become relatively tighter, causing the hardness of the copper wire to increase slightly and its flexibility to decrease. Therefore, when winding the stator, the wire drawing from the accumulated copper wire reel will become slower, affecting the winding efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a stator winding machine for a brushless motor to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a stator winding machine for a brushless motor, comprising a frame, a winding device is fixedly connected to the top of the frame, a mounting roller is rotatably connected to the outer wall of the winding device, a first fixing component and a second fixing component are movably connected to the outer wall of the mounting roller, a bracket is fixedly connected to the outer wall of the frame, and a buffer mechanism is fixedly connected to the outer wall of the bracket; The buffer mechanism comprises: A connecting rod, the outer wall of which is fixedly connected to the outer wall of the bracket; A first bearing, wherein the bottom of the first bearing is fixedly connected to the top of the connecting rod; An impact rod, the outer wall of which is rotatably connected to the outer wall of the first bearing; A first rotating disk, wherein an outer wall of the first rotating disk is fixedly connected to an outer wall of the impact rod.

[0005] Preferably, a third bearing is fixedly connected to the top of the bracket, a vibration block is rotatably connected to the outer wall of the third bearing, and the vibration block is in active contact with the impact rod.

[0006] Preferably, the outer wall of the vibration block is fixedly connected to a second turntable, and a belt is sleeved between the second turntable and the outer wall of the first turntable.

[0007] Preferably, the outer wall of the third bearing is rotatably connected to a cross bar, and the copper wire will be pulled by the rotating rod during the rotation process, and then the copper wire will be pulled out from the copper wire pile in advance, and the copper wire will be pulled in advance by the up and down swing of the rotating rod, and then it will be pulled by the winding equipment and wound around the stator, reducing the difficulty of pulling the copper wire and ensuring the winding efficiency of the stator. The cross bar will drive the movement of the gravity block during the rising and falling process. When the cross bar is tilted, the gravity block will drop under its own gravity, so the vibration of the cross bar is generated, and the vibration extends to the copper wire. When the copper wire rubs against other copper wires, the vibration will temporarily keep the copper wire away from the friction, thereby improving the pulling efficiency of the copper wire. The outer wall of the bracket is fixedly connected to a motor.

[0008] Preferably, the motor is fixedly connected to the cross bar via a rotating shaft, a limiting groove is provided on the outer wall of the cross bar, a gravity block is inserted into the inner wall of the limiting groove, and the outer wall of the cross bar is rotatably connected to two rotating rods, so that the cross bar can drive the rotation of the second turntable during rotation, and the size of the second turntable is larger than that of the first turntable, so the first turntable rotates multiple times when the second turntable rotates one circle, and the impact rod hits the vibration block during rotation to generate vibration, which is transmitted to the copper wire, so the cross bar swings when driving the copper wire to vibrate, which increases the vibration of the copper wire, facilitates the pulling of the copper wire, and ensures the winding efficiency of the stator.

[0009] Preferably, a guide mechanism is fixedly connected to the outer wall of the bracket, and the guide mechanism comprises a slide rail, and the slide rail is fixedly connected to the outer wall of the bracket.

[0010] Preferably, an outer wall of the slide rail is slidably connected to an electric slider, and an outer wall of the electric slider is fixedly connected to a mounting rod.

[0011] Preferably, the outer wall of the mounting rod is rotatably connected to a second bearing, and the top of the second bearing is fixedly connected to a guide rod, and the arc of the guide rod is arranged along the center of rotation of the rotating rod, so that the guide rod will squeeze the copper wire located in the rotating rod during the movement, thereby playing a role of pulling the copper wire, and utilizing the squeezing of the copper wire to produce the pulling of the copper wire on the copper wire drum, thereby making the copper wire removed from the copper wire drum in advance for subsequent use, and when the toggle block passes the position of the toggle block, the two are squeezed, and then the guide rod will be driven to change its angle, and when the guide rod swings, it will pull the copper wire to swing, thereby causing the copper wire to be further pulled, increasing the pulling force on the copper wire, thereby facilitating the pulling of the copper wire and ensuring the winding efficiency of the stator, the bottom of the second bearing is fixedly connected to a toggle block, the outer wall of the bracket is also fixedly connected to the toggle block, the toggle block is in movably contact with the toggle block, and the outer wall of the mounting rod is also fixedly connected to a limiting rod.

[0012] The present invention provides a stator winding machine for a brushless motor, which has the following beneficial effects: 1. The stator winding machine of the brushless motor pulls the copper wire through the rotating rod during the rotation process, and then pulls the copper wire out of the copper wire pile in advance. The copper wire is pulled in advance by the up and down swing of the rotating rod, and then it is pulled by the winding equipment and wound around the stator, which reduces the difficulty of pulling the copper wire and ensures the winding efficiency of the stator. The cross bar drives the gravity block to move during the rising and falling process. When the cross bar is tilted, the gravity block will drop under its own gravity, so the vibration of the cross bar is generated, and the vibration extends to the copper wire. When the copper wire rubs against other copper wires, the vibration will temporarily keep the copper wire away from the friction, thereby improving the pulling efficiency of the copper wire.

[0013] 2. The stator winding machine of the brushless motor utilizes the cross bar to drive the second turntable to rotate during the rotation process. The size of the second turntable is larger than that of the first turntable. Therefore, when the second turntable rotates one circle, the first turntable rotates multiple circles. The impact rod hits the vibration block during the rotation process to generate vibration. The vibration is transmitted to the copper wire, so when the cross bar drives the copper wire to vibrate, it swings, which increases the vibration of the copper wire, facilitates the pulling of the copper wire, and ensures the winding efficiency of the stator.

[0014] 3. The stator winding machine of the brushless motor is arranged along the center of rotation of the rotating rod through the arc of the guide rod, so the guide rod will squeeze the copper wire in the rotating rod during the activity, thereby pulling the copper wire. The squeezing of the copper wire produces pulling of the copper wire on the copper wire drum, so that the copper wire is removed from the copper wire drum in advance for subsequent use. When the toggle block passes the position of the toggle block, the two are squeezed, and then the guide rod is driven to change its angle. When the guide rod swings, it pulls the copper wire to swing, and then the copper wire is further pulled, which increases the pulling force on the copper wire, facilitates the pulling of the copper wire, and ensures the winding efficiency of the stator.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] For example, see Figure 1-6The present invention provides a technical solution: a stator winding machine for a brushless motor, comprising a frame 1, a winding device 2 is fixedly connected to the top of the frame 1, a mounting roller 4 is rotatably connected to the outer wall of the winding device 2, a first fixing component 3 and a second fixing component 5 are movably connected to the outer wall of the mounting roller 4, a bracket 6 is fixedly connected to the outer wall of the frame 1, and a buffer mechanism 7 is fixedly connected to the outer wall of the bracket 6; The buffer mechanism 7 comprises: A connecting rod 71, the outer wall of the connecting rod 71 is fixedly connected to the outer wall of the bracket 6; A first bearing 73, the bottom of which is fixedly connected to the top of the connecting rod 71; An impact rod 74, the outer wall of the impact rod 74 is rotatably connected to the outer wall of the first bearing 73; The first turntable 72, the outer wall of the first turntable 72 is fixedly connected to the outer wall of the impact rod 74, and the cross bar 11 drives the second turntable 76 to rotate during the rotation process. The size of the second turntable 76 is larger than that of the first turntable 72. Therefore, when the second turntable 76 rotates one circle, the first turntable 72 rotates multiple circles. During the rotation process, the impact rod 74 hits the vibration block 77 to generate vibration, and the vibration is transmitted to the copper wire. Therefore, the cross bar 11 swings when driving the copper wire to vibrate, which increases the vibration of the copper wire, facilitates the pulling of the copper wire, and ensures the winding efficiency of the stator.

[0020] The top of the bracket 6 is fixedly connected with a third bearing 10 , and the outer wall of the third bearing 10 is rotatably connected with a vibration block 77 , and the vibration block 77 is in active contact with the impact rod 74 .

[0021] The outer wall of the vibration block 77 is fixedly connected with a second rotating disk 76 , and a belt 75 is sleeved between the second rotating disk 76 and the outer wall of the first rotating disk 72 .

[0022] The outer wall of the third bearing 10 is rotatably connected to a cross bar 11 , and the outer wall of the bracket 6 is fixedly connected to a motor 9 .

[0023] The motor 9 is fixedly connected to the cross bar 11 through a rotating shaft. During the rotation process, the copper wire will be pulled by the rotating rod 12, and then the copper wire will be pulled out from the copper wire pile in advance. The copper wire is pulled in advance by the up and down swing of the rotating rod 12, and then it is pulled by the winding device 2 and wound around the stator, reducing the difficulty of pulling the copper wire and ensuring the winding efficiency of the stator. The cross bar 11 is used to drive the movement of the gravity block 14 during the rising and falling process. When the cross bar 11 is tilted, the gravity block 14 will drop under its own gravity, so the vibration of the cross bar 11 is generated, and the vibration extends to the copper wire. When the copper wire rubs against other copper wires, the vibration will temporarily keep the copper wire away from the friction, thereby improving the pulling efficiency of the copper wire. A limiting groove 13 is provided on the outer wall of the limiting groove 13, and the gravity block 14 is inserted into the inner wall of the limiting groove 13. The outer wall of the cross bar 11 is rotatably connected to two rotating rods 12.

[0024] When in use, the stator to be wound is placed on the installation roller 4, and then the first fixing component 3 and the second fixing component 5 fix the stator, and then the winding device 2 is powered on to start winding the stator on the installation roller 4; Combined with Figure 3 As shown, the copper wire passes between two rotating rods 12, is guided by the rotating rods 12, and is then pulled and wound on the stator by the winding device 2. The motor 9 is powered on and started. A control element is provided in the motor 9, so that the motor 9 rotates sixty degrees clockwise and then sixty degrees counterclockwise. During the rotation, the copper wire is pulled by the rotating rods 12, so that the copper wire is pulled out of the copper wire pile in advance. In addition, the cross bar 11 drives the gravity block 14 to move during the rising and falling process. When the cross bar 11 is tilted, the gravity block 14 will fall under its own gravity, so the vibration of the cross bar 11 is generated, and the vibration extends to the copper wire, so that the copper wire is smoothly pulled off the copper wire drum. Combined with Figure 6 As shown, the cross bar 11 will drive the second turntable 76 to rotate during the rotation process. The second turntable 76 will drive the first turntable 72 to rotate through the belt 75 during the rotation process. The size of the second turntable 76 is larger than the first turntable 72, so when the second turntable 76 rotates one circle, the first turntable 72 rotates multiple circles. When the first turntable 72 rotates, it drives the impact rod 74 to rotate. During the rotation process, the impact rod 74 hits the vibration block 77 to generate vibration. The vibration is transmitted to the copper wire, so the cross bar 11 swings when driving the copper wire to vibrate.

[0025] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The outer wall of the bracket 6 is fixedly connected with a guide mechanism 8 , and the guide mechanism 8 includes a slide rail 84 , and the slide rail 84 is fixedly connected to the outer wall of the bracket 6 .

[0026] An electric slider 85 is slidably connected to the outer wall of the slide rail 84 , and a mounting rod 86 is fixedly connected to the outer wall of the electric slider 85 .

[0027] The outer wall of the mounting rod 86 is rotatably connected to the second bearing 83, and the top of the second bearing 83 is fixedly connected to the guide rod 88. The arc of the guide rod 88 is arranged along the center of rotation of the rotating rod 12, so the guide rod 88 will squeeze the copper wire located in the rotating rod 12 during the activity, thereby playing a role in pulling the copper wire. The squeezing of the copper wire produces the pulling of the copper wire on the copper wire drum, thereby making the copper wire be removed from the copper wire drum in advance for subsequent use. When the toggle block 82 passes the position of the toggle block 81, the two are squeezed, and then the guide rod 88 will be driven to change its angle. When the guide rod 88 swings, it will pull the copper wire to swing, thereby causing the copper wire to be further pulled, increasing the pulling force on the copper wire, thereby facilitating the pulling of the copper wire and ensuring the winding efficiency of the stator. The bottom of the second bearing 83 is fixedly connected to the toggle block 82, and the outer wall of the bracket 6 is also fixedly connected to the toggle block 81. The toggle block 82 is in active contact with the toggle block 81, and the outer wall of the mounting rod 86 is also fixedly connected to the limiting rod 87.

[0028] When in use, the electric slider 85 is powered on and starts to move on the slide rail 84, and then the electric slider 85 drives the guide rod 88 to move. The arc of the guide rod 88 is set along the center of the circle of the rotating rod 12, so the guide rod 88 will squeeze the copper wire in the rotating rod 12 during the movement, thereby playing a role in pulling the copper wire, and the copper wire can be normally pulled by the winding device 2 under the active pulling of the guide rod 88; Combined with Figure 8 As shown, a toggle block 82 is provided at the bottom of the second bearing 83, and when the toggle block 82 passes the position of the toggle block 81, the two are squeezed, and then the guide rod 88 is driven to change its angle. The limit rods 87 are provided on both sides of the guide rod 88 to limit the angle range of the guide rod 88, so when the guide rod 88 swings, it pulls the copper wire to swing, and then the copper wire is further pulled; After the work is completed, the first fixing component 3 and the second fixing component 5 are not fixed to the stator, and the stator can be removed.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
