Description

Technical Field

[0002] The stator is the stationary part of an electric motor or generator, mainly composed of three parts: the stator core, the stator windings, and the frame.

The stator windings are part of the stator and are usually made by winding wires on the stator core using a winding machine. Most of the winding machines currently used are single-station winding machines.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0031] The preferred embodiment of the present invention is a dual-station synchronous stator winding machine, such as... Figure 1 As shown, see also Figures 2-7 The system includes a synchronous material transfer unit 1, a synchronous material receiving unit 2, and a synchronous winding unit 3. The synchronous material transfer unit 1 includes two rotating arms 10, a first drive unit 11 that drives the two rotating arms 10 to rotate synchronously horizontally, and a lifting unit 12 that drives the first drive unit 11 to rise and fall. The rotation axis of each rotating arm 10 is located at its center, and both ends of each rotating arm 10 are equipped with grippers 13 for gripping the stator core. The synchronous material receiving unit 2 includes two receiving platforms 20, two sets of corresponding slide rails 21 for sliding on the receiving platforms 20, and a second drive unit 22 that drives either receiving platform 20 to move. The two receiving platforms 20 are connected by a first connecting rod 23, and both ends of the first connecting rod 23 are equipped with helical gears 2. 30. The synchronous receiving unit 2 also includes two helical racks 24 that cooperate with the helical gears 230; the receiving platform 20 is provided with a stator core jig 25 that corresponds to receiving the stator core on the gripper 13 and a clamp for holding the stator core; the synchronous winding unit 3 includes a winding frame 30, a first Y-axis mechanism 31 that drives the winding frame 30 to move laterally along the distribution direction of the two receiving platforms 20 and two wire supply units 32. The winding frame 30 is provided with two sets of winding arms 33, a Z-axis mechanism 34 that drives the two sets of winding arms 33 to move synchronously up and down, two sets of wire clamps 35, two sets of wire cutters 36, and a second Y-axis mechanism 37 that drives the two sets of wire clamps 35 and the two sets of wire cutters 36 to move laterally along the distribution direction of the two receiving platforms 20.

[0032] After the two stator cores are delivered to the loading position, the lifting unit 12 drives the first drive unit 11 to descend, and the grippers 13 on the two rotating arms 10 grab the stator cores accordingly. Then, the lifting unit 12 drives the first drive unit 11 to ascend, and the first drive unit 11 drives the two rotating arms 10 to rotate 180 degrees synchronously, so that the stator cores reach the receiving position. The lifting unit 12 can be in the form of a cylinder, lead screw, etc., and there is no limitation on it. The grippers 13 can be implemented using existing structures. The first drive unit 11 can adopt the following structure or an existing robotic arm structure.

[0033] The second drive unit 22 drives one of the receiving platforms 20 to the receiving position, and drives the other receiving platform 20 to the receiving position through the first connecting rod 23. During the movement of the two receiving platforms 20, they maintain synchronization by cooperating with two sets of helical gears 230 and helical racks 24. It should be noted that the synchronization of this step is completed by cooperating with the first connecting rod 23, helical gears 230 and helical racks 24, which can ensure high synchronization accuracy while simplifying the structure, reducing the number of drives and the cost of synchronization debugging. It is also one of the core features of achieving dual-station synchronization in this application.

[0034] The lifting unit 12 drives the first drive unit 11 to move downward, the stator core enters the corresponding stator core fixture 25, the gripper 13 is released, and the fixture holds the stator core; the two receiving platforms 20 move to the winding position under the drive of the second drive unit 22.

[0035] Before winding, the copper wire is pulled out by the wire supply unit 32, passes through the winding arm 33, and is held by the wire clamp 35. During winding, the first Y-axis mechanism 31 and the Z-axis mechanism 34 work together to drive the two winding arms 33 to wind the wire. The second drive unit 22 drives the two receiving platforms 20 to move in coordination. After winding is completed, the second Y-axis mechanism 37 drives the wire clamp 35 and the wire cutter 36 to the tail wire to cut the tail wire and the wire clamp 35 re-holds the cut wire end. This facilitates continuous winding of the next product. Of course, the wire end of the stator core after winding can also be further trimmed, which can be set as needed.

[0036] The two receiving platforms 20 move to the receiving position under the drive of the second drive unit 22, the clamps are released, the lifting unit 12 drives the first drive unit 11 to move down, the gripper 13 clamps the stator core, the lifting unit 12 drives the first drive unit 11 to move up, and the first drive unit 11 drives the two rotating arms 10 to rotate 180 degrees synchronously, so that the stator core reaches the loading position.

[0037] The device of this application can achieve synchronous operation of two winding stations in a reasonable manner, which can improve winding efficiency and ensure the consistency of products on the two winding stations. The overall structure is reasonable and compact with high space utilization. It should be noted that, based on the dual-station synchronous structure provided in this application, the number of synchronous winding stations can be further increased to achieve synchronous methods such as three-station or four-station. The solution obtained by simply increasing the number is also within the scope of protection of this application.

[0038] Preferably, to better facilitate the synchronous operation of the two winding stations, this application also employs a novel winding arm 33 structure, which includes a connecting seat 330, a longitudinally elongated support arm 331, and a C-shaped winding head 332.

The upper part of 2 is longitudinally rotatably connected, and the lower part of the winding head 332 is provided with a wire tube 334. The first wire member 335 is provided on the support arm 331.

[0039] With this structural design, the elongated support arm 331 can extend into the stator core together with the winding head 332 for winding. The winding head 332 adopts a C-shaped structure, which can be freely rotated around the rotation connection point with the support arm 331 by the push rod 333, so as to flexibly adjust the winding angle. Of course, the shape of the winding head can also be replaced with a U-shaped or similar shape. The solution obtained by the conventional replacement of such similar shapes also falls within the scope of protection of this application. The drive of the push rod 333 is achieved by the drive motor 3361 driving the lead screw 3360, which in turn drives the movable seat 3362, thus achieving high precision.

The dual-station synchronous stator winding machine according to claim 6, characterized in that, The rotating arm includes a rotating base and a rotating column rotatably mounted on the rotating base. The rotating base is fixed to the lifting plate. The first drive unit includes a rotating motor fixed to the lifting plate. The rotating motor is located between the two rotating bases. The movable end of the rotating motor faces upward and drives the two rotating columns to rotate synchronously through a synchronous belt assembly. A tensioning wheel assembly for tensioning the synchronous belt is provided on the rotating motor.

8. A dual-station synchronous stator winding method, applied to the dual-station synchronous stator winding machine as described in any one of claims 1-7, characterized in that, The method includes the following steps: After the two stator cores are delivered to the feeding position, the lifting unit drives the first drive unit to descend, and the grippers on the two rotating arms grab the stator cores accordingly. Then the lifting unit drives the first drive unit to ascend, and the first drive unit drives the two rotating arms to rotate 180 degrees synchronously, so that the stator cores reach the receiving position. The second drive unit drives one of the receiving platforms to the receiving position, and drives the other receiving platform to the receiving position through the first connecting rod. The two receiving platforms maintain synchronization during the movement by means of the cooperation of two sets of helical gears and helical racks. The lifting unit drives the first drive unit to descend, the stator core enters the corresponding stator core fixture, the grippers release, and the fixture holds the stator core; the two receiving platforms move to the winding position under the drive of the second drive unit. Before winding, the copper wire is pulled out by the wire supply unit, passes through the winding arm, and is held by the wire clamp. During winding, the first Y-axis mechanism and the Z-axis mechanism work together to drive the two winding arms to wind the wire. The second drive unit drives the two receiving platforms to move in coordination. After winding is completed, the second Y-axis mechanism drives the wire clamp and wire cutter to the tail wire, cuts the tail wire, and the wire clamp holds the cut wire end again. The two receiving platforms move to the receiving position under the drive of the second drive unit. The clamps are released, the lifting unit drives the first drive unit to move downward, the grippers hold the stator core, the lifting unit drives the first drive unit to move upward, and the first drive unit drives the two rotating arms to rotate 180 degrees synchronously, so that the stator core reaches the loading position.
