Description

TECHNICAL FIELD

[0001] The utility model relates to flat wire motor stator production technical field especially relates to a kind of wire pushing device for flat wire motor disassembly. BACKGROUND

[0002] Flat wire motor is usually composed of stator, rotor, speed reducer etc., and flat wire motor stator is one of the core components of flat wire motor. Stator is the stationary component of motor, usually composed of coil wound by copper wire, and is installed in motor housing fixedly. Its main role is to generate magnetic field, push rotor to rotate and complete motor operation

[0003] The main role of flat wire motor stator is to generate magnetic field, which can be constant direct-current magnetic field or variable alternating-current magnetic field. When the current through the stator coil changes, magnetic flux will change in the conductor, and this magnetic flux change will affect the form of magnetic field, which determines the rotation direction and speed of rotor. The magnetic field generated in the stator interacts with the magnetic field presented in the rotor, so that the rotor rotates under the action of torque.

[0004] Flat wire motor has wide application in new energy vehicles, but its production process is complex, the input cost is high, the processing difficulty is great, and the yield is low. At present, the yield of flat wire in the production process of flat wire motor is about 90-98%, and in the early product production verification stage, it is as high as 30-50%. At present, manufacturers can only manually disassemble and scrap the defective products. Especially in the flat wire disassembly process, angle grinder, manual scissors and wire saw are usually used for disassembly of copper wire. When disassembling copper wire, the copper wire will move in the flat wire motor, especially when the copper wire is pulled out, the inner wall of the iron core will be damaged, which leads to the fact that the disassembled flat wire motor cannot be recycled and reused. This disassembly is a great waste for the high-cost investment in the early stage of flat wire motor production.

[0005] There is no special tooling and equipment for motor recycling in the production process at present. The utility model provides a kind of wire pushing device for flat wire motor disassembly, which pushes the sheared copper wire out of the iron core. UTILITY MODEL CONTENTS

[0006] To solve the above technical problems, the utility model provides a kind of wire pushing device for flat wire motor disassembly. The utility model pushes the sheared copper wire out of the iron core through the push rod on the wire pushing device after fixing the flat wire motor through the tensioning rotary displacement device, so as to ensure that the iron core will not be scratched and can be reused.

[0008] The bracing rotary displacement device is used for fixing the flat wire motor to the pushing wire station.

[0009] The pushing wire device is used for pushing the part of the flat wire in the flat wire motor which is not exposed outside the iron core out.

[0010] The pushing wire device comprises a top wire cylinder, a guard rod cylinder, a top rod, a guide block and a bearing platform.

[0011] The guard rod cylinder is connected with the bearing platform through a guard rod, and the guide block is fixed on the bearing platform.

[0012] One end of the top rod penetrates through the guide block, and the other end is connected with the top wire cylinder through a transmission mechanism.

[0013] The top wire cylinder is used for driving the top rod to stretch out from the guide block.

[0014] The guard rod cylinder is used for driving the bearing platform and the guide block to move upward, so that the rod-retracting action of the guide block is completed.

[0015] Preferably, the bracing rotary displacement device comprises an inner bracing clamp, an R-axis servo motor assembly, an inner bracing cylinder and a rotary slip ring.

[0016] The inner bracing cylinder is used for opening the inner bracing clamp to fix the flat wire motor.

[0017] The R-axis servo motor assembly is connected with the rotary slip ring.

[0018] The rotary slip ring is driven and controlled by the R-axis servo motor assembly to rotate the flat wire motor.

[0019] Preferably, the bracing rotary displacement device further comprises an X-axis servo motor assembly and a Z-axis electric cylinder assembly.

[0055] Example

[0056] In a specific embodiment 1, Figure 1-4 As shown, a wire pushing device for disassembling a flat wire motor includes a tightening and rotating position changing device 1 and a wire pushing device 2;

[0057] The tightening rotation position changing 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 carrying platform 2-5;

[0060] The guard rod cylinder 2-2 is connected to the carrying platform 2-5 through the guard rod; the guide block 2-4 is fixed on the carrying 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 cylinder 2-1 through the transmission mechanism;

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

[0063] The rod guard 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 positioner 1 further includes an X-axis servo motor assembly 1-5 and a Z-axis electric cylinder assembly 1-6;

[0069] 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 and rotating position changing 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 structure.

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

[0074] When pushing the wire, the rotating positioner 1 is tightened to fix the flat wire motor 100 on 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 internal support fixture 1-1 supports the inner diameter of the flat wire motor's core, while also offering a wide range of travel to accommodate flat wire motors with a wider inner diameter. In this embodiment, the internal support fixture 1-1 includes three arms. When clamping the flat wire motor, the three arms utilize their own weight to contact the motor's inner wall. During lifting, the applied force is converted into supporting force and friction, thus also providing air-off protection. The internal support cylinder 1-3 is used to drive the internal support fixture 1-1 open or closed. By controlling the stroke of the internal support cylinder 1-3, the degree of opening of the internal support fixture 1-1 can be controlled, thereby accommodating flat wire motors of varying 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 movement is achieved by controlling the lifting 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 rotary slip ring 1-4 through a belt drive, thereby driving the internal 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 internal support cylinder 1-3 in the tightening rotation displacement device 1 controls the internal support clamp 1-1 to open inside the flat wire motor 100 to be disassembled, and then sends the flat wire motor 100 to be disassembled 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 rotary displacement device 1 is tightened to fix the flat wire motor 100, the wire pushing cylinder 2-1 controls the push rod 2-3 to be pushed out. During the pushing, the lower surface of the carrying platform 2-5 is in contact with 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 insertion slot to be pushed, so that the push rod 2-3 can smoothly enter the wire insertion slot, thereby pushing out the copper wire in the wire insertion 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. 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 ventilated and extended to ensure 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 replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
