Description

Technical Field

[0001] The invention belongs to the field of stator winding, and in particular relates to a winding device for a brushless motor stator. Background Art

[0002] A winding machine is a device that winds a linear object onto a specific workpiece, usually used for copper wire winding. Most electrical products need to be wound into inductor coils with enameled copper wire (enameled wire for short), and a winding machine can be used to complete this or multiple processes. For example: various motors, coreless motors, rotors, stators, pin inductors, chip inductors, transformers, solenoid valves, straight inductors, resistors, ignition coils, RFID, mutual inductors, audio coils, IC card high and low frequency coils, focusing coils, etc. In a winding machine, the winding device is mainly used to realize winding. When winding, the current winding machine winds the copper wire from the lower end of the stator PIN needle to the upper end of the stator PIN needle, and then winds the stator body from the upper end. However, the distance between the top of the PIN needle and the stator body is relatively farther, and the copper wire is easier to break. If the winding starts from the lower end of the stator PIN needle to the upper end of the stator PIN needle, and then the copper wire is wound back from the upper end of the stator PIN needle to the lower end of the stator PIN needle, although the problem of easy disconnection of the copper wire is solved, the copper wire on the PIN needle is too much wound, which affects the installation and use of the stator. In the existing winding machine, there is no device that can directly wind the copper wire from the upper end of the stator PIN needle to the lower end of the stator PIN needle and then wind the stator body. In addition, the current winding devices generally have the problems of complex structure and low efficiency. Summary of the invention

[0003] In order to solve the above problems, the primary purpose of the present invention is to provide a winding device for a brushless motor stator, which can prevent the copper wire wound on the stator from breaking when winding the stator, thereby making the stator produced and processed have a higher yield rate.

[0004] Another object of the present invention is to provide a winding device for a brushless motor stator, which has a simple structure and is more efficient when winding the stator.

[0005] In order to achieve the above purpose, the technical solution of the present invention.

[0006] A winding device for a brushless motor stator, the device comprising a winding mechanism, a stator placement mechanism and a winding mechanism equipped with copper wire, the stator placement mechanism is provided with a processing position for placing a stator to be wound, and is characterized in that the winding mechanism comprises a winding three-axis motion mechanism, a wire clamping assembly and a winding assembly, the wire clamping assembly and the winding assembly are both fixedly arranged on the winding three-axis motion mechanism, the wire clamping assembly and the winding assembly can be moved in the three directions of X, Y and Z under the drive of the winding three-axis motion mechanism, and the wire clamping assembly, the winding assembly and the winding mechanism all correspond to the processing position. During the processing of the device, the copper wire on the winding mechanism is clamped by the winding assembly and the clamping assembly in turn. Through the movement of the winding assembly and the clamping assembly, the copper wire between the winding assembly and the clamping assembly is fixedly wound around the top of the stator PIN needle (that is, the clamping assembly remains stationary after the position is determined, and the winding assembly winds the copper wire around the PIN needle so that the copper wire is wound and fixed around the top of the PIN needle). At this time, the clamping assembly loosens or breaks the copper wire, and the winding assembly wraps the copper wire between it and the stator PIN needle from the top of the PIN needle to the bottom of the PIN needle. After reaching the bottom of the PIN needle, the winding assembly loosens the copper wire. At this time, the copper wire is driven by the rotation of the winding mechanism to be wound around the stator body. By winding the stator with the device, the copper wire between the PIN needle and the stator body can be prevented from being disconnected, so that the stator produced has a higher yield rate. In addition, the device has a simple structure and is more efficient when winding the stator. The stator placement mechanism is a structure for placing the stator, which is a prior art. For example, the stator placement mechanism is equivalent to a self-locking material turning mechanism with a patent application number of "CN201821179804.2"; or equivalent to a combination of a turning mechanism and a level-changing mechanism in a multi-station three-dimensional winding machine with a patent application number of "CN201820785359.8". The winding mechanism is a prior art, which is used to realize winding of the rotor body by rotation. For example, the winding mechanism is equivalent to a combination of a winding mechanism and a driving mechanism in a multi-station three-dimensional winding machine with a patent application number of "CN201820785359.8".

[0007] Furthermore, the wire winding three-axis motion mechanism includes a wire winding support frame, a wire winding three-axis motion assembly and a wire clamping three-axis motion assembly, the wire winding three-axis motion assembly and the wire clamping three-axis motion assembly are both fixedly arranged on the wire winding support frame, the wire clamping assembly and the wire winding assembly are respectively fixedly arranged on the wire clamping three-axis motion assembly and the wire winding three-axis motion assembly, and the wire clamping assembly and the wire winding assembly are respectively driven by the wire clamping three-axis motion assembly and the wire winding three-axis motion assembly to move in the three directions of X, Y, and Z.

Moreover, the wire winding component moves in three directions of X, Y, and Z driven by the wire winding three-axis motion component, and the wire clamping component moves in two directions of Y and Z driven by the wire clamping two-axis motion component. The realization of the wire clamping two-axis motion component is prior art, such as realized by the following wire clamping Y-axis motion component and wire clamping Z-axis motion component.

[0009] Furthermore, the wire winding three-axis motion component includes a wire winding X-axis motion component, a wire winding Y-axis motion component, and a wire winding Z-axis motion component. The wire winding X-axis motion component is fixedly arranged on the upper side of the wire winding support frame. The wire winding Y-axis motion component is fixedly arranged on the upper side of the wire winding X-axis motion component. The wire winding Z-axis motion component is fixedly arranged on the side of the wire winding Y-axis motion component. The implementation principles of the above-mentioned wire winding X-axis motion component, wire winding Y-axis motion component, and wire winding Z-axis motion component are all prior art, and can respectively realize the movement of the wire winding component in three directions of X, Y, and Z, and can all be realized by using a motor and a lead screw.

[0010] Furthermore, the wire clamping three-axis motion component includes a wire clamping X-axis motion component, a wire clamping Y-axis motion component, and a wire clamping Z-axis motion component. The wire clamping X-axis motion component is fixedly arranged on the lower side of the wire clamping support frame. The wire clamping Y-axis motion component is fixedly arranged beside the X-axis motion component. The Z-axis motion component is fixedly arranged on the Y-axis motion component. The above-mentioned position distribution of the wire winding three-axis motion component and the wire clamping three-axis motion component on the wire clamping support frame makes more reasonable use of space, and enables the device to use fewer components and the structure to be relatively simpler. The implementation principles of the above-mentioned wire clamping X-axis motion component, wire clamping Y-axis motion component, and wire clamping Z-axis motion component are all prior art, and can respectively realize the movement of the wire clamping component in three directions of X, Y, and Z, and can all be realized by using a cylinder.

[0011] Furthermore, the overall shape of the wire winding support frame is "冂"-shaped, and the stator placement mechanism is located under the wire winding support frame. This setting makes more reasonable use of space.

[0012] Furthermore, the wire clamping component includes a wire clamping cylinder that can clamp the copper wire, and the wire clamping cylinder is located beside the processing position. The above-mentioned wire clamping cylinder is prior art and can clamp the copper wire.

[0013] Furthermore, the wire winding component includes a wire winding cylinder that can clamp the copper wire, and the wire winding cylinder is located above the processing position. The above-mentioned wire winding cylinder is prior art and can clamp the copper wire.

[0014] Furthermore, the stator placement mechanism is provided with two processing positions, the winding mechanism corresponds to the two processing positions respectively, the number of the wire clamping assembly and the wire winding assembly are both two, the two wire clamping assemblies correspond to the two processing positions respectively, and the two wire winding assemblies correspond to the two processing positions respectively. That is, the two processing positions can place two stators for simultaneous processing, and the two wire clamping assemblies and the two wire winding assemblies respectively wind the corresponding stator PIN needles, and the winding mechanism winds the stator bodies of the two stators.

[0015] Furthermore, the device also includes a device body, and the winding mechanism, stator placement mechanism and winding mechanism are all fixedly arranged on the device body.

[0016] The beneficial effect of the present invention is that, compared with the prior art, in the present invention, the copper wire on the winding mechanism is clamped by the winding assembly and the clamping assembly in turn, and the copper wire between the winding assembly and the clamping assembly is fixedly wound around the top of the stator PIN needle through the movement of the winding assembly and the clamping assembly. At this time, the clamping assembly loosens or breaks the copper wire, and the winding assembly wraps the copper wire between it and the stator PIN needle from the top of the PIN needle to the bottom of the PIN needle. After reaching the bottom of the PIN needle, the winding assembly loosens the copper wire, and at this time, the copper wire is driven by the rotation of the winding mechanism to be wound around the stator body. By winding the stator with the device, the copper wire between the PIN needle and the stator body can be prevented from being disconnected, so that the stator produced has a higher yield rate. In addition, the device has a simple structure and is more efficient when winding the stator. BRIEF DESCRIPTION OF THE DRAWINGS
