Description

Technical Field

[0001] The invention relates to the technical field of flat wire motor stator production, and in particular to a wire pushing device for disassembling a flat wire motor. Background Art

[0002] Flat wire motors are usually composed of stators, rotors, reducers, etc., and the stator of flat wire motors is one of the core components of flat wire motors. The stator is the stationary part of the motor, usually composed of a coil wound with copper wire, and is installed in the motor housing and fixed. Its main function is to generate a magnetic field, drive the rotor to rotate, and complete the operation of the motor.

[0003] The main function of the flat wire motor stator is to generate a magnetic field, which can be a constant DC magnetic field or a variable AC magnetic field. When the current passing through the stator coil changes, the magnetic flux in the conductor will change, which will affect the shape of the magnetic field, and the shape of the magnetic field determines the direction and speed of rotation of the rotor. The magnetic field generated in the stator interacts with the magnetic field in the rotor, causing the rotor to rotate under the action of torque.

[0004] Flat wire motors are widely used in new energy vehicles, but the production process of flat wire motors is complex, the investment cost is high, the processing is difficult, and the yield rate is low. At present, the yield rate of the whole line in the production link of flat wire motors is about 90-98%, and it is as high as 30-50% in the early product production verification stage. At this stage, major manufacturers can only manually dismantle and scrap defective products, especially in the flat wire dismantling link, generally using angle grinders, manual shears, wire saws, etc. to dismantle the copper wire. When dismantling the copper wire, the copper wire will move in the flat wire motor, especially when the copper wire is pulled out, it will damage the inner wall of the iron core. This makes it impossible to recycle and reuse the disassembled flat wire motor. Considering the high cost investment in the early stage of flat wire motor production, such dismantling is a huge waste.

[0005] In view of the fact that there are currently no special tools and equipment for motor recycling in the production process on the market, the present invention proposes a wire pushing device for disassembling flat wire motors to push the sheared copper wire out of the iron core. Summary of the invention

[0006] In order to solve the above technical problems, the present invention proposes a wire pushing device for disassembling a flat wire motor. The present invention fixes the flat wire motor by tightening the rotating displacement device, and then pushes the sheared copper wire out of the iron core through the push rod on the wire pushing device, ensuring that the iron core will not be scratched, so that it can be reused. The technical solution of the present invention is implemented as follows:

[0007] A wire pushing device for disassembling a flat wire motor, comprising a tightening, rotating and position changing device and a wire pushing device;

[0008] The tightening and rotating position changing device is used to fix the flat wire motor to the wire pushing station;

[0009] The wire pushing device is used to push out the portion of the flat wire in the flat wire motor that is not exposed outside the iron core;

[0010] The wire pushing device comprises a wire pushing cylinder, a rod protection cylinder, a push rod, a guide block and a bearing platform;

[0011] The guard rod cylinder is connected to the carrying platform via the guard rod; the guide block is fixed on the carrying platform;

[0012] One end of the push rod passes through the guide block, and the other end is connected to the push line cylinder through a transmission mechanism;

[0013] The ejector cylinder is used to drive the ejector rod to extend from the guide block;

[0014] The rod protection cylinder is used to drive the bearing platform and the guide block to move upward, thereby completing the rod retracting action of the guide block.

[0015] Preferably, the tightening and rotating displacement device comprises an inner support fixture, an R-axis servo motor assembly, an inner support cylinder and a rotating slip ring;

[0016] The inner support cylinder is used to open the inner support clamp to fix the flat wire motor;

[0017] The R-axis servo motor assembly is connected to the rotating slip ring;

[0018] The rotating slip ring is driven by the R-axis servo motor assembly to control the rotation of the flat wire motor.

[0019] Preferably, the tightening and rotating displacement device further comprises an X-axis servo motor assembly and a Z-axis electric cylinder assembly;

[0020] The X-axis servo motor assembly is used to control the flat wire unit to move along the X-axis;

[0021] The Z-axis electric cylinder assembly is connected to the rotating slip ring.

[0022] Preferably, the tightening and rotating displacement device further comprises a variable diameter servo motor assembly;

[0023] The variable diameter servo motor assembly is connected to the wire pushing device via a screw rod structure.

[0024] The advantages of the present invention are as follows:

[0025] A guide block is used to guide the push rod to ensure that the push rod will not deviate when pushing the wire, thereby causing the push rod to bend or the copper wire in the iron core to deviate from the travel direction when pushing the wire and damage the inner wall of the iron core.

[0026] The push rod is extended by the push rod cylinder, and the stator is pushed out by the push rod after the copper wires at both ends are cut off. The rod protection cylinder completes the rod retracting action of the guide block of the push rod to prevent the push rod from being aligned with the notch accurately and bending when the push rod is used for a stator with large thickness.

[0027] The variable diameter servo motor assembly is combined with the lead screw module to perform X-axis load transfer and diameter change for flat wire motors of different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example

[0056] In a specific embodiment 1, Figure 1-4 As shown, a wire pushing device for disassembling a flat wire motor comprises a tightening rotation displacement device 1 and a wire pushing device 2;

[0057] The tightening rotation displacement device 1 is used to fix the flat wire motor 100 to the wire pushing station;

[0058] The wire pushing device 2 is used to push out the portion of the flat wire in the flat wire motor 100 that is not exposed outside the iron core;

[0059] The wire pushing device 2 includes a wire pushing cylinder 2-1, a rod protection cylinder 2-2, a push rod 2-3, a guide block 2-4 and a bearing platform 2-5;

[0060] The guard rod cylinder 2-2 is connected to the bearing platform 2-5 through the guard rod; the guide block 2-4 is fixed on the bearing platform 2-5;

[0061] One end of the push rod 2-3 passes through the guide block 2-4, and the other end is connected to the push line cylinder 2-1 through a transmission mechanism;

[0062] The push-line cylinder 2-1 is used to drive the push rod 2-3 to extend from the guide block 2-4;

[0063] The rod protection cylinder 2-2 is used to drive the bearing platform 2-5 and the guide block 2-4 to move upward, thereby completing the rod retracting action of the guide block 2-4.

[0064] In this embodiment, the tightening rotation displacement device 1 includes an inner support fixture 1-1, an R-axis servo motor assembly 1-2, an inner support cylinder 1-3 and a rotating slip ring 1-4;

[0065] The inner support cylinder 1-3 is used to open the inner support clamp 1-1 to fix the flat wire motor 100;

[0066] The R-axis servo motor assembly 1-2 is connected to the rotating slip ring 1-4;

[0067] The rotating slip ring 1-4 is driven by the R-axis servo motor assembly 1-2 to control the rotation of the flat wire motor 100.

[0068] In some embodiments, the tightening and rotating displacement device 1 further includes an X-axis servo motor assembly 1-5 and a Z-axis electric cylinder assembly 1-6;

[0069] The X-axis servo motor assembly 1-5 is used to control the flat wire unit to move along the X-axis;

[0070] The Z-axis electric cylinder assembly 1-6 is connected to the rotating slip ring 1-4.

[0071] In this embodiment, the tightening rotation displacement device 1 further includes a variable diameter servo motor assembly 1-7;

[0072] The variable diameter servo motor assembly 1-7 is connected to the wire pushing device 2 through a screw rod structure.

[0073] Since different flat wire motors have different diameters, in order to adapt to flat wire motors of various specifications, it is necessary to adjust the distance between the top wire rod and the inner support center. The variable diameter servo motor assembly 1-7 controls the wire pushing device 2 to move along the x-axis direction to adapt to flat wire motors of different specifications.

[0074] When pushing the wire, the rotating displacement device 1 is tightened to fix the flat wire motor 100 above the workbench, and then the wire pushing device 2 pushes out the copper wire in the flat wire motor 100 that is not exposed outside the iron core.

[0075] In this embodiment, the inner support fixture 1-1 supports the inner diameter of the iron core of the flat wire motor, and the large stroke is suitable for flat wire motors with a larger inner diameter range. In this embodiment, the inner support fixture 1-1 includes three support arms. When clamping the flat wire motor, the three support arms use their own gravity to contact the inner wall of the flat wire motor. During the lifting process, the force is converted into support force and friction force, so it can also play the role of air-cutting and anti-falling protection. The inner support cylinder 1-3 is used to drive the inner support fixture 1-1 to open or close. Through the stroke control of the inner support cylinder 1-3, the degree of opening of the inner support fixture 1-1 can be controlled, so as to be compatible with flat wire motors of different specifications.

[0076] In this embodiment, the rotating slip ring 1-4 plays a role in making the R-axis rotation of the inner support fixture 1-1 compatible with the Z-axis movement direction. The R-axis rotation is controlled by the R-axis servo motor assembly 1-2, and the Z-axis lifting and lowering movement is achieved by controlling the lifting and lowering of the rotating slip ring 1-4 by the Z-axis electric cylinder assembly 1-6.

[0077] In this embodiment, the R-axis servo motor assembly 1-2 rotates the motor at equal angles, and rotates the rotating slip ring 1-4 through the belt drive, thereby driving the inner support fixture 1-1 to rotate, thereby achieving the displacement action of each slot;

[0078] The specific workflow of this embodiment is as follows:

[0079] The inner support cylinder 1-3 in the tightening rotation displacement device 1 controls the inner support clamp 1-1 to open inside the flat wire motor 100 to be disassembled, and then the flat wire motor 100 to be disassembled is sent to the wire pushing station through the X-axis servo motor assembly 1-5, the Z-axis electric cylinder assembly 1-6, and the variable diameter servo motor assembly 1-7 (at this time, the copper wire exposed outside the iron core of the flat wire motor 100 has been cut).

[0080] When the flat wire motor 100 is fixed by tightening the rotating displacement device 1, the wire pushing cylinder 2-1 controls the push rod 2-3 to be pushed out. During the pushing, the lower surface of the supporting platform 2-5 fits the upper surface of the flat wire motor 100, and the guide block 2-4 is located at the notch of the iron core wire slot to be pushed, so that the push rod 2-3 can smoothly enter the wire slot, thereby pushing out the copper wire in the wire slot. When the copper wire is completely pushed out, the wire pushing cylinder 2-1 controls the push rod 2-3 to retreat.

[0081] When the push line cylinder 2-1 lowers the push rod 2-3, the rod protection cylinder 2-2 always remains in the extended air supply state, and the compression return end of the rod protection cylinder 2-2 uses a muffler and is not connected to the air source. The rod protection cylinder 2-2 is equivalent to a spring that can be extended with air, ensuring that the push rod 2-3 will not bend when withdrawing.

[0082] The R-axis servo motor assembly 1-2 controls the rotation of the rotating slip ring 1-4, and then controls the rotation of the inner support clamp 1-1, driving the flat wire motor 100 to rotate, aligning the wire slot of the next wire to be pushed with the guide block 2-4, and then repeating the above process until all the copper wires in the iron core are pushed out.

[0083] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
