Description

Technical Field

[0001] This utility model relates to a carbon fiber feeding device, belonging to the field of carbon fiber rotor production technology for motors. 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 method for carbon fiber winding involves attaching a magnet to the surface of a rotating shaft, then winding a carbon fiber rope or strip coated with adhesive around the circumference formed by the magnet. However, this winding process often results in uneven thickness in certain areas, leading to imbalances. Carbon fiber cloth, a high-performance composite material, possesses advantages such as lightweight, high strength, high rigidity, wear resistance, corrosion resistance, and good high-temperature performance. After processing, the carbon fiber cloth requires a feeding device. Once a feeding roller has finished feeding the cloth, it needs to be replaced with a new one for subsequent feeding operations. Currently, replacing the feeding roller is cumbersome, requiring cutting the carbon fiber cloth, fixing the cut end to the new feeding roller, and installing the new roller. This results in significant downtime and is inconvenient for winding multiple layers of carbon fiber, thus reducing the feeding efficiency of the carbon fiber cloth. Therefore, a carbon fiber feeding device is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a motor rotor-driven carbon fiber feeding device. This device employs a servo-driven carbon fiber feeding system, which uses a forward-moving frame and a transverse mechanism to drive the carbon fiber feeding. It is equipped with a heating component and a vision inspection head, resulting in a compact and reasonable structure that is less likely to damage the carbon fiber. The device offers high carbon fiber feeding accuracy, strong adaptability, and improves the efficiency and quality of the feeding process before carbon fiber winding, while also ensuring high safety.

[0005] The purpose of this utility model is achieved through the following technical solution: A carbon fiber feeding device includes a support plate and a transverse mechanism mounted on the support plate. A forward moving frame is mounted on the transverse moving mechanism, and a carbon fiber mounting frame, a tension roller group, a feeding roller, a tension sensing roller, and a drive roller group are set on the forward moving frame. The mounting frame is connected to a brake. A compaction roller is set below the drive roller group. A heating component is installed in front of the drive roller group. A cutting component is set behind the heating component. A detection adjustment frame is also installed on the forward moving frame. A vision detection head is mounted on the detection adjustment frame. A vision controller is also installed on the forward moving frame. Carbon fibers are manually placed onto the mounting frame, and the carbon fiber strips are installed in the following order: tension roller assembly, feeding roller, tension sensing roller and drive roller assembly, heating assembly, and compaction roller. The forward-moving frame is driven by a servo motor and positioned in conjunction with the carbon fiber winding device with the rotor installed. After being heated by the heating assembly, the carbon fiber strips are wound onto the rotor. When the end of the carbon fiber first reaches the rotor, the compaction roller can directly contact the area of ​​the rotor with the wrapped carbon fiber, thus pressing the carbon fiber wrapped onto the rotor, that is, pressing the end of the carbon fiber film onto the rotor. The compaction roller and the rotor driven by the winding device roll towards each other, thereby winding the carbon fiber strip onto the rotor. Driven by a traversing mechanism, the machine reciprocates. The rotor surface is uniformly wound with multiple layers of carbon fiber. The carbon fiber strips are cut by a cutting assembly, preventing the carbon fiber from falling off the rotor and improving the effectiveness of the multi-layer winding. During winding, each turn of carbon fiber forms a layer, and the rotor can be moved back and forth, increasing winding efficiency. Simultaneously, when adjacent carbon fiber layers come into contact, they overlap sequentially along the rotation direction of the carbon fiber film. Therefore, during winding, gas between adjacent carbon fiber films is forced out through the openings between them, preventing air bubbles from forming between the carbon fiber layers and improving the winding effect, thus better protecting the rotor. A vision inspection head captures real-time side images of the rotor, which are sent to a processor. The processor analyzes the images to determine the diameter D of the rotor after the carbon fiber cloth is wound. Based on the diameter D and the rotation speed of the rotor's servo motor, the speed of the drive roller servo motor is adjusted. This reduces manual labor intensity and significantly improves product quality. The wound carbon fiber rotor can be automatically output by a robotic arm, facilitating connection with upstream and downstream processes.

[0006] Preferably, the compaction roller includes a roller frame, a roller wheel mounted on the roller frame, a guide rail slider, and a limiting rod. The roller frame is connected to a compaction cylinder via a floating joint. The compaction cylinder is mounted on a cylinder bracket. The roller wheel is in close contact with the carbon fiber cloth.

[0007] Preferably, the detection and adjustment frame is equipped with a vision detection head, which can acquire side images of the rotor in real time and send the side images to the processor. The processor analyzes the images to obtain the diameter D of the rotor after it is wrapped with carbon fiber cloth, and adjusts the speed of the servo motor of the drive roller group according to the diameter D and the rotation speed of the rotor servo motor.

[0008] Preferably, the surface of the heating component is provided with an anti-stick coating, the heating block is driven to open and close by a cylinder, and a cooling facility is provided.

[0009] The beneficial effects of this utility model are: (1) The motor rotor winding carbon fiber feeding device is a servo-driven carbon fiber feeding device. It drives the carbon fiber feeding through the forward moving frame and the transverse moving mechanism. It is equipped with a heating component and a vision inspection head. It can move and reciprocate to wind multiple layers of carbon fiber on the rotor, thereby improving the winding efficiency and product quality; (2) The surface of the heating component is provided with an anti-stick coating. Since the carbon fiber strip needs to be heated at the heating component, the carbon fiber film will not stick to the heating component when it moves, so the movement of the carbon fiber film is smoother; (3) The carbon fiber mounting frame is connected to a brake and the feeding roller is connected to a magnetic powder clutch. The brake and the magnetic powder clutch can adjust the tension of the carbon fiber film when it is pulled out from the mounting frame and the feeding roller. By controlling the tension sensing roller, it can ensure that the carbon fiber film will not wrinkle when it moves, avoid the generation of air bubbles between the winding carbon fiber layers, and improve the product quality of the carbon fiber rotor.
