Description

Technical Field

[0001] The invention relates to a winding device for a brushless motor, in particular to a single-head inner winding machine capable of winding relatively thick copper wires. Background Art

[0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product.

[0003] In recent years, brushless motors have become a driving force for rapid development in the model field. Due to production and price reasons, brushless motors have been mostly used in mid-to-high-end aviation models in the past few years. Now, due to the rapid development of mechanical processing technology, the production cost of brushless motors has dropped a lot. At present, it is entering all levels of the model field, from electric remote control cars to electric remote control boats to electric model airplanes, and is everywhere.

[0004] Structurally, brushless motors are similar to brushed motors in that they both have rotors and stators, but their structures are opposite to those of brushed motors. The rotor of a brushless motor is a permanent magnet, which is connected to the output shaft together with the casing. The stator is a winding coil, and the commutation brushes used by brushed motors to alternately transform the electromagnetic field have been removed, so it is called a brushless motor.

[0005] An important production link of brushless motors is stator winding. It is usually done by manually semi-automatically operated inner winding machines, which results in low work efficiency and relatively high labor costs. In addition, it is impossible to wind thicker wires and the winding arm cannot be rotated 90 degrees, which makes it relatively difficult to remove the stator later.

[0047] This structure is composed of four groups of axes X / Y / Z / U, and the controller connected to the device later controls each electrical device to return to the origin position and gives a control signal. First, the wire is placed on the corresponding winding disk, and the tension is adjusted by the tensioner 60. Then, the wire head is fixed on the winding fork 24 after passing through the wire clamp 30, and the stator is placed on the winding disk skeleton 4 for fixation. At this time, the equipment is started and the movement is controlled. The front, back, left and right movements on the X-axis and Y-axis respectively play the role of arranging the wire and finding the working origin. At the same time, the Z-axis drives the winding fork 24 to move up and down, and finally realizes the winding of the stator. At the same time, the U-axis motor 2 can realize positive and reverse rotation so that the Z-axis moves up and down to cooperate with the winding fork 24 to move up and down from the product slot type, and ensure coordination with the Z-axis. At the same time, the application needs to explain that the specific rotation angle is related to the winding method diagram of the stator product (that is, the number of slots and how many slots are spanned), and this belongs to the program setting of the later control part and belongs to the conventional technology in this field, so it is not described in detail. The specific working principle is: after power-on and resetting, the controller connected later checks whether each axis is in place, the wire is manually placed on the wire trimming cylinder, and the wire head is fixed while trimming the wire (how to fix it is also a conventional technology, so it is not described in detail here), and each coordinate of the equipment returns to the origin (the so-called origin can be arbitrarily selected on the screen corresponding to the controller, and at the same time, according to the product characteristics, a point suitable for product winding is selected as the origin (the specific origin of the winding point is also determined by the conventional technology in this field, so it is not described in detail here)), and then the material is manually loaded. The stator is clamped in the winding disc skeleton 4 through the clamping assemblies on both sides, and the stator is fixed on the feeding mold of the winding disc skeleton 4. After pressing the start button, the X and Y coordinates move accordingly, and the U axis cooperates to rotate left and right to hang the initial hook. Then, the winding process is carried out according to the winding schematic diagram provided by the customer. When winding, in order to adapt to the winding of thick wires, the vertical winding arm 66 is clamped in the clamping mouth 26 of the clamping block 25. At this time, the clamping block 25 will The winding arm 66 is clamped, so that when the wire is too thick, the winding arm is prevented from being slightly deformed and scratching the copper wire due to excessive tension, which further facilitates the winding of thicker wires. At the same time, the present invention realizes that after each winding of a slot on the stator, the swing arm flip motor 18 is driven to extend, driving the swing rod 21 below to swing, and finally the other end of the swing rod 21 drives the winding arm 66 to rotate, move out of the clamp 26, and change from the original vertical state to a horizontal device, finally making the swing arm assembly rotate 90°, so that the thread end can be hung on the outside of the stator to avoid affecting the removal of the stator. Then after the winding is completed, the U axis returns to the original position to ensure that the first cylinders on both sides are just aligned with the clamping rod 52, and then the first cylinder 55 extends out to the top of the clamping rod 52 to ensure that the lower end of the clamping rod 52 is close to the winding disc skeleton 4. At this time, the pressure block 53 that presses the stator above is loosened, and the wire cutting cylinder 56 extends out to the thread end, and then the pneumatic wire cutting nozzle 57 works to cut the wire, and finally the stator is taken out manually.

[0048] Therefore, this structure has the following technical advantages: 1. In order to adapt to the winding of thick wires, the vertical winding arm 66 is clamped in the clamping opening 26 of the clamping block 25. At this time, the clamping block 25 will clamp the winding arm 66, which can prevent the winding arm from being slightly deformed and scratching the copper wire due to excessive tension when the wire is too thick, and further facilitate the winding of thicker wires; 2. After each slot on the stator is wound, the swing arm flip motor 18 is driven to extend, driving the swing arm 21 below to swing, and finally the other end of the swing arm 21 drives the winding arm 66 to rotate, move out of the clamping opening 26, and change from the original vertical state to a horizontal device, finally making the swing arm assembly rotate 90°, so that the wire end can be hung on the outside of the stator to avoid affecting the removal of the stator; 3. Moreover, automatic winding is realized, which further improves work efficiency, reduces labor costs and safety.
