Description

Technical Field

[0001] The utility model relates to the technical field of flat wire motor stator production, in particular to a paper extraction device for disassembling a flat wire motor. Background Art

[0002] Flat wire motors are usually composed of stators, rotors, reducers, etc., and the stator 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 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 primary function of a flat wire motor's stator is to generate a magnetic field, which can be either a constant DC field or a variable AC field. When the current flowing through the stator coil changes, the magnetic flux in the conductor changes. This flux change affects the shape of the magnetic field, which in turn determines the direction and speed of the rotor's rotation. The magnetic field generated in the stator interacts with the magnetic field in the rotor, causing the rotor to rotate due to the 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 entire line in the production 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 process, which generally uses angle grinders, hand shears, wire saws, etc. to disassemble the copper wire. When disassembling the copper wire, the copper wire will move in the flat wire motor and damage the inner wall of the iron core. This makes the disassembled flat wire motor unable to be recycled and reused. Considering the high cost investment in the early stage of flat wire motor production, such disassembly is a huge waste.

[0005] In addition, in addition to the thread removal process, the paper removal process may also cause damage to the iron core due to improper operation or other factors, such as mechanical collision caused by operational errors, which may cause the iron core to warp.

[0006] To this end, the utility model proposes a paper extraction device for disassembling a flat wire motor, which solves the disadvantages of manual operation through mechanized operation and realizes automatic and safe paper extraction. Utility Model Content

[0009] The bracing and rotating displacement device is used for fixing the flat wire motor to the paper drawing station; the paper drawing device is used for drawing the insulating paper in the wire insertion slot of the flat wire motor.

[0010] The paper drawing device comprises a paper drawing air cylinder assembly and air shears clamps.

[0015] The R-axis servo motor assembly is connected to the rotating slip ring.

[0016] The rotating slip ring is driven and controlled by the R-axis servo motor assembly to rotate the flat wire motor.

[0017] The rotary support platform is used for supporting the flat wire motor.

[0018] Preferably, the bracing and rotating displacement device further comprises a quick-change disc.

[0019] The quick-change disc is provided with a plurality of uniform fixing teeth arranged on the outer periphery.

[0020] The quick-change disc is coaxially sleeved below the inner bracing clamp.

[0021] Preferably, the bracing and rotating displacement device further comprises a gas jet nozzle and a material discharging slide plate.

[0022] The gas jet nozzle is used for blowing the drawn paper on the air shears clamps to the material discharging slide plate.

[0023] Preferably, the flat wire motor fixing assembly further comprises a synchronous wheel.

[0024] The synchronous wheel is coaxially sleeved with the rotating slip ring.
