Description

Technical Field

[0001] The present invention relates to the technical field of flat wire motor disassembly, and in particular to a flat wire motor disassembly mechanism and method. Background Art

[0002] Flat wire motors are usually composed of stators, rotors, reducers, etc., and the stator of a flat wire motor is one of the core components of a flat wire motor. The stator is the stationary part of the motor, usually composed of a coil wound with copper wire, and is fixed in the motor housing. 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% to 98%, and it is as high as 30% to 50% in the early product production verification stage. At this stage, major manufacturers can only manually disassemble and scrap defective products, especially in the flat wire disassembly link, generally using angle grinders, manual shears, wire saws, etc. to disassemble the copper wire. When disassembling 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 disassembly 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 flat wire motor disassembly mechanism for disassembling the copper wire in the flat wire motor while protecting the internal iron core from damage so that it can be reused.

[0079] The second aspect of the present invention discloses a flat wire motor disassembly method, the method uses the flat wire motor disassembly mechanism disclosed in the first aspect of the present invention, and the method comprises the following steps:

[0080] S1, placing the flat wire motor to be disassembled at the wire cutting station through the clamping unit on the flat wire motor transplanting device;

[0081] S2, the first tightening and rotating position changing device fixes the position of the flat wire motor;

[0082] S2, driving the cutter unit on the wire cutting device to cut the copper wire portion exposed on the lower surface of the iron core;

[0087] Preferably, it also includes S6, the first tightening rotation displacement device is retracted, and the flat wire motor transfer device transfers the iron core after the wire pushing is completed to the paper drawing station;

[0088] S7, the second tightening and rotating displacement device fixes the iron core;

[0090] S9, the second tightening and rotating displacement device is retracted; the flat wire motor transfer device transfers the iron core after the paper drawing is completed to the cleaning station;

[0091] S10, using a cleaning device to clean the recovered iron core; after the cleaning is completed, enter SN.

[0092] The advantages of the present invention are as follows:

[0093] First, compared with the traditional manual wire removal using tools such as angle grinders, hand shears, and wire saws, which will damage the inner wall of the iron core and make it impossible to reuse it, the present invention uses two cutters on the cutter device in combination with a driving unit to achieve automatic wire cutting, and the two opposite cutters cooperate with the floating unit to concentrate the shearing force on both sides of the copper wire when cutting the copper wire. The first tightening and rotating displacement device can well fix the flat wire motor at the cutter position, so that the copper wire inside the iron core will not swing left and right and scratch the inner wall of the iron core during wire cutting. The floating unit allows the left and right cutters to automatically correct the deviation to prevent the single-sided cutter from being subjected to large force, resulting in the copper wire cutting surface being inclined outwardly greater than the iron core slot, thereby ensuring that when the wire pushing device draws out the copper wire inside the iron core, the copper wire will not scratch the inner wall of the slot.

[0094] Second, the wire pushing device uses a guide block 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 direction of travel and damage the inner wall of the iron core when pushing the wire.

[0095] 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 guide block retracting action of the push rod to prevent the push rod from being accurate to the notch and bending when the push rod is used for a thick stator. The variable diameter servo motor assembly cooperates with the screw module to perform X-axis load transfer and diameter change for flat wire motors of different diameters.

[0096] Third, the second rotating slip ring combined with the quick-change plate can effectively protect the iron core and prevent the iron core from warping when pulling paper.

[0097] The changeable motor assembly combined with the quick-change disc can meet the paper extraction operations of flat wire motors of different models.

[0098] Fourth, the dust cover on the cleaning device can effectively prevent waste from splashing during cleaning. The cleaning nozzle that can rotate 360 ​​degrees can achieve dead-angle cleaning of the iron core, and the cleaning effect can be better ensured when combined with the waste collection device.

[0099] Fifth, the flat wire motor transplanting device cooperates with the above device to realize the fully automatic mechanical disassembly of the flat wire motor. And the inner wall of the iron core after disassembly is intact and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0177] In this embodiment, the first tightening and rotating position changing device 1 is used to fix the flat wire motor 100 to the wire cutting station and the wire pushing station.

The dust cover cylinder 7-7 is connected to the dust cover 7-5; the dust cover cylinder 7-7 is used to control the lifting and lowering of the dust cover 7-5.

[0195] In this embodiment, the rotating mechanism 7 - 2 is a servo motor.

[0196] In this embodiment, the waste collection mechanism 7-4 includes a lower dust suction pipe 7-4-1; the lower dust suction pipe 7-4-1 is used to collect dust and stains on the iron core to prevent waste from splashing.

[0197] In this embodiment, the flat wire motor transplanting device 8 includes a clamping unit 8-1, a flipping unit 8-2, a transplanting slide rail 8-3 and a second lifting mechanism 8-4; the flipping unit 8-2 is used to flip the clamping unit 8-1. The second lifting mechanism 8-4 is slidably arranged on the transplanting slide rail 8-3; the flipping unit 8-2 is fixed on the second lifting mechanism 8-4. In this embodiment, the flat wire motor is clamped by the clamping unit 8-1, the flat wire motor is rotated at the cutting station and the pushing station by the flipping unit 8-2, and the sliding transportation of the flat wire motor is realized by the transplanting slide rail 8-3.

[0198] The specific workflow of this embodiment is as follows:

[0199] Wire cutting: After the clamping unit 8-1 on the flat wire motor transplanting device places the flat wire motor 100 to be disassembled at the wire cutting station, the first tightening and rotating displacement device 1 fixes the position of the flat wire motor above the workbench 3, and the wire cutting device 2 cuts the copper wire exposed outside the iron core of the flat wire motor 100. In this embodiment, a hydraulically driven synchronous cylinder 2-2 is used to drive the cutter unit 2-1 to move, thereby cutting the copper wire. The floating unit 2-4 is used to eliminate the asynchronous shearing stress. The floating unit 2-4 in this embodiment is a spring. The spring can make the cutters on the left and right sides automatically correct when the synchronous cylinder 2-2 cuts the copper wire, so as to prevent the copper wire cutting surface from being tilted outwardly larger than the iron core slot due to the large force on one side, which is not conducive to damaging the inner wall of the slot when the copper wire is ejected.

[0200] Furthermore, the floating adjustment bolt 2-7 adjusts the floating amount and compression force of the floating unit 2-4, so as to adapt to more specifications of flat wires or adjust the floating parameters. The cross bearing 2-3 provides sliding action for the floating of the synchronous cylinder 2-2. The laser sensor 2-6 is used to detect whether the copper wire cutting is completed to ensure that the copper wire is cut without adhesion.

[0201] Wire pushing: The wire pushing cylinder 4-1 controls the push rod 4-3 to push out. When pushing out, the lower surface of the carrying platform 4-5 fits the upper surface of the flat wire motor 100, and the guide block 4-4 is located at the notch of the iron core wire slot to be pushed, so that the push rod 4-3 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 4-1 controls the push rod 4-3 to retreat.

[0202] When the push line cylinder 4-1 lowers the push rod 4-3, the rod protection cylinder 4-2 always remains in the extended air supply state, and the compression return end of the rod protection cylinder 4-2 uses a muffler and is not connected to the air source. The rod protection cylinder 4-2 is equivalent to a spring that can be ventilated and extended to ensure that the push rod 4-3 will not bend when withdrawing.

[0203] The first R-axis servo motor assembly 1-2 controls the rotation of the first rotating slip ring 1-4, and then controls the rotation of the first inner support clamp 1-1, driving the flat wire motor 100 to rotate, aligning the next wire insertion slot to be pushed with the guide block 4-4, and then repeating the above process until all the copper wires in the iron core are pushed out.

[0204] Paper extraction: The flat wire motor transplanting device 8 transplants the flat wire motor 100 after the wire pushing is completed to the paper extraction station. The second inner support fixture 6-1 supports the inner diameter of the iron core of the flat wire motor 100. The paper extraction cylinder assembly 5-1 includes a rodless cylinder, which provides power for the air scissor clamp 5-2 with a stroke of 200mm, driving the air scissor clamp 5-2 to extract the insulating paper from the iron core. The air nozzle 6-7 is connected to the air pipe to blow off the extracted insulating paper. The installation position of the air nozzle 6-7 can be adjusted up and down, and it can be fixed in a suitable position with good effect.

[0205] The stroke control of the second inner support cylinder 6-3 can control the degree of opening of the second inner support fixture 6-1, so as to be compatible with flat wire motors 100 of different specifications. The second R-axis servo motor assembly 6-2 rotates the motor at equal angles, and drives the second rotating slip ring 6-4 to rotate through the synchronous wheel 6-9, thereby driving the second inner support fixture 6-1 to rotate, so as to achieve the displacement action of each slot; the slewing support platform 6-5 is fixed on the column, and the second R-axis servo motor assembly 6-2 drives the synchronous wheel 6-9 gear transmission to achieve the effect of rotating the flat wire motor 100; until the insulating paper in all slots is pulled out.

[0206] This embodiment can achieve quick compatibility with products of different models and sizes by replacing the quick-change disk 6-6. At the same time, the quick-change disk 6-6 acts as a tooth guard to prevent the iron core in the flat wire motor 100 from warping during paper extraction. When replacing a flat wire motor 100 of a different model, the corresponding position of the air scissor clamp 5-2 is adjusted by the type-changing electric cylinder.

[0207] Cleaning: The flat wire motor transfer device 8 transfers the flat wire motor 100 (only the iron core is left) after the paper drawing is completed to the cleaning station. The dust cover cylinder 7-7 controls the dust cover 7-5 to cover the iron core on the dust removal platform 7-6, and the rotating mechanism 7-2 controls the cleaning nozzle 7-3 to clean the iron core 360 ​​degrees. The cleaned debris, dust and other impurities are collected and processed by the waste collection mechanism 7-4.

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.
