Description

TECHNICAL FIELD

[0001] The utility model relates to flat wire motor stator production technical field, especially in a kind of flat wire motor disassembling wire shearing device. 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 stator coil changes, magnetic flux variation will be generated in the conductor, which will affect the form of magnetic field, and the form of magnetic field determines the rotation direction and speed of rotor.The magnetic field generated in stator interacts with the magnetic field presented in rotor, so that rotor rotates under the action of torque.

[0004] Flat wire motor has wide application in new energy vehicles, but its production process is complex, investment cost is high, processing difficulty is great, and yield is low.At present, the yield of straightening in the production process of flat wire motor is about 90-98%, and in the early product production verification stage, it is even 30-50%.At present, manufacturers can only manually disassemble and scrap the defective products, especially in the flat wire disassembly process, which is usually carried out by using angle grinder, manual scissors and wire saw to disassemble copper wire.As the copper wire moves in the flat wire motor, the inner wall of the iron core is damaged, which leads to the fact that the disassembled flat wire motor cannot be recycled and reused, which is a great waste of 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, so the utility model provides a wire shearing device for disassembling flat wire motor, which can protect the inner wall of the iron core from being scratched when disassembling copper wire, so that the disassembled iron core can be reused. UTILITY MODEL CONTENTS

[0006] In order to solve the above technical problems, the utility model provides a wire shearing device for disassembling flat wire motor, which can fix flat wire motor through tensioning rotary displacement device, and then cut the exposed part of flat wire outside the iron core through two cutter units on wire cutting device, so as to ensure that the iron core will not be scratched and can be reused.The technical scheme of the utility model is as follows:

[0007] A wire shearing device for disassembling flat wire motor, comprising tensioning rotary displacement device and wire cutting device;

[0008] The tensioning rotary displacement device is used to fix the flat wire motor to the cutting station.

[0009] The cutting device is used to cut the part of the flat wire exposed outside the core in the flat wire motor.

[0010] The cutting device comprises two cutter units, a driving unit and a floating unit.

[0011] The driving unit is connected to at least one of the cutter units, and the floating unit is connected to the driving unit.

[0012] The cutter unit comprises a cutter.

[0013] Preferably, the cutting device further comprises a mounting seat; the cutter unit and the driving unit are arranged on the mounting seat.

[0014] Preferably, the driving unit comprises a synchronous cylinder and a cross bearing.

[0015] The synchronous cylinder is connected to at least one of the cutter units through the cross bearing.

[0016] Preferably, the cutting device further comprises a laser sensor.

[0017] The laser sensor is used to detect whether the cutting of the flat wire is completed.

[0018] Preferably, the tensioning rotary displacement device comprises an inner support clamp, an R-axis servo motor assembly, an inner support cylinder and a rotary slip ring.

[0019] The inner support cylinder is used to open the inner support clamp to fix the flat wire motor.

[0020] The R-axis servo motor assembly is connected to the rotary slip ring.

[0021] The rotary slip ring is driven by the R-axis servo motor assembly to control the rotation of the flat wire motor.

[0022] Preferably, the tensioning rotary displacement device further comprises an X-axis servo motor assembly and a Z-axis cylinder assembly.

[0023] The X-axis servo motor assembly is used to control the movement of the flat wire unit along the X-axis.

[0024] The Z-axis cylinder assembly is connected to the rotary slip ring.

[0025] Preferably, a workbench is further comprised; the cutting device is fixed to the workbench.

[0026] The tensioning rotary displacement device is arranged above the workbench.

[0027] Preferably, the tangent device further includes a floating adjustment bolt.

[0028] The advantages of this utility model are as follows:

[0029] Compared to traditional manual wire dismantling using tools such as angle grinders, hand shears, and wire saws, which can damage the inner wall of the iron core and prevent its reuse, this utility model uses two cutters on a cutting device combined with a drive unit to achieve automatic wire cutting. The two opposing cutters, together with a floating unit, concentrate the shearing force on both sides of the copper wire when cutting it. The tightening and rotating positioning device can effectively fix the flat wire motor at the cutting position. In this way, the copper wire inside the iron core will not sway left and right and scratch the inner wall of the iron core when cutting, thus ensuring that the iron core can still be reused after the flat wire motor is dismantled.

[0030] The floating unit in this invention allows the left and right cutters to automatically correct their deviation, preventing the large force on one side of the cutter from causing the copper wire cutting surface to tilt outwards beyond the iron core slot opening. This ensures that when the copper wire is pulled out of the iron core, the copper wire will not scratch the inner wall of the slot opening. Attached Figure Description
