Description

Technical Field

[0001] This utility model relates to a carbon fiber wound motor rotor manufacturing device, belonging to the field of carbon fiber motor rotor production technology. Background Technology

[0002] With the rapid development of the automotive industry, automotive motors are gradually moving towards higher efficiency, higher power, and higher speed. In new energy vehicles, the increasing demand for motor power density has led to a reduction in motor mass. Specifically, by increasing the motor speed while keeping the output power constant, the size and weight of the motor can be reduced, thereby increasing the power density. To prevent damage to the rotor due to centrifugal force during high-speed rotation, a carbon fiber rotor sleeve can be added to the outside of the rotor to protect it.

[0003] Currently, the conventional carbon fiber winding process involves attaching magnets to the surface of a rotating shaft and then winding carbon fiber ropes or strips coated with adhesive around the circumference formed by the magnets. After winding, uneven thickness in some areas can easily occur, resulting in imbalance. Existing methods to eliminate this imbalance include rolling the carbon fiber cylindrical surface before the adhesive cures, but rolling is difficult to achieve a highly precise cylindrical surface; or turning or grinding the carbon fiber cylindrical surface after the adhesive has cured, but turning and grinding can cause carbon fiber filament breakage and damage to the structural strength of the carbon fiber. Therefore, existing carbon fiber winding equipment can no longer meet the requirements for product efficiency and quality. There is a great need for rotor carbon fiber winding equipment with a high degree of automation, high structural strength of carbon fiber, and high precision of the cylindrical surface. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a carbon fiber winding device for motor rotors. This servo-driven carbon fiber winding device uses a lifting mechanism and a tightening mechanism to fix the rotor and rotate it to wind carbon fiber. It has a compact and reasonable structure, is not prone to damaging the carbon fiber, and allows for convenient and quick rotor clamping. It is highly adaptable, improves the efficiency and quality of the carbon fiber winding process, and is also highly safe.

[0005] The purpose of this utility model is achieved through the following technical solution: A carbon fiber rotor winding device includes a support plate and a tightening mechanism and a rotating mechanism mounted on the support plate, as well as a lifting mechanism set on the guide rail slider of the tightening mechanism. A screw seat, an adjusting handle, an adjusting screw and an adjusting locking frame are installed on one side of the tightening mechanism. An adjusting nut matching the adjusting screw is set on the same side of the lifting mechanism. A rotor can be placed on the lifting mechanism. A detection component is also set on the support plate. The rotor is placed onto the rotor support of the lifting mechanism by a person or a robot. The lifting mechanism raises the rotor. After adjusting the distance between the lifting mechanism and the clamping mechanism by adjusting the handle, the clamping bracket is locked and fixed. The transfer servo motor in the clamping mechanism drives the shaft at one end of the rotor into the three-jaw chuck of the rotating mechanism for fixation. Then, the clamping cylinder clamps and fixes the rotor through the clamping head. The rotor support of the lifting mechanism falls back to its original position. The rotor rotates and winds carbon fiber with the three-jaw chuck of the rotating mechanism driven by the servo motor. The position status of the clamping mechanism can be detected by the detection component. The manual labor intensity is low, and the product quality is greatly improved. The rotor with the wound carbon fiber can be automatically output by a robot, which is convenient for connection with the previous and subsequent processes.

[0006] This utility model provides a carbon fiber rotor winding device. The clamping mechanism includes a transfer servo motor, a guide rail slider and a limiting bracket mounted on a support plate. A movable seat is mounted on the guide rail slider. A limiting pressure plate is provided at the front of the movable seat and a clamping seat is provided at the top. A clamping head and a clamping cylinder are respectively installed at the front and rear of the clamping seat. The transfer servo motor drives the movable seat to move back and forth through a gear and rack. The limiting bracket restricts the extreme position of the transfer rotor.

[0007] This invention provides a carbon fiber rotor winding device. The lifting mechanism includes a lifting cylinder and a movable plate mounted on a guide rail slider of the tightening mechanism. The lifting cylinder is fixed to the movable plate by a cylinder seat. An adjusting seat is mounted on the piston rod of the lifting cylinder. The adjusting seat is equipped with an adjusting bracket and a rotor bracket. The adjusting bracket is fixed in conjunction with a centering adjustment mechanism. The centering adjustment mechanism drives the two bracket plates of the rotor bracket to move towards or away from each other to a suitable position for placing the rotor. The lifting cylinder drives the adjusting seat to raise the rotor bracket to a predetermined position.

[0008] Preferably, the clamping mechanism and the lifting mechanism are connected by an adjusting screw and an adjusting nut. The distance between the clamping mechanism and the lifting mechanism can be adjusted to a suitable position according to the specifications of the rotor and then locked in place. A detection component is provided to detect the position of the clamping mechanism.

[0009] The beneficial effects of this utility model are that the carbon fiber rotor winding device is a servo-driven rotor carbon fiber winding device. The servo motor drives the lifting mechanism and the clamping mechanism to transfer and clamp the rotor. After clamping and fixing, the rotating mechanism rotates the rotor. The servo actuator in the winding machine can be controlled by adjusting the position, speed, and torque to achieve high-precision transmission system positioning, reduce damage to the carbon fiber, and improve product quality. The structural design of the two servo motors avoids the accumulation of carbon fiber filaments on the servo motors. The overvoltage, overcurrent, overheat, and undervoltage fault detection and protection circuits in the servo controller improve the overall safety of the winding device, preventing accidents. It reduces manual labor intensity, greatly improves product quality, and after the rotor with wound carbon fiber passes inspection, it is output by a robotic arm, facilitating connection with upstream and downstream processes. It has a high degree of automation and requires no assembly skills from the operator, thus improving production efficiency. Attached Figure Description
