Description

Technical Field

[0001] The invention relates to a carbon fiber transverse feeding detection device, belonging to the technical field of motor carbon fiber rotor production. Background Art

[0002] With the rapid development of the automobile industry, automotive motors are gradually developing towards high efficiency, high power and high speed. In new energy vehicles, the requirements for motor power density are gradually increasing, which makes the mass of the motor smaller and smaller. Among them, by increasing the speed of the motor while keeping the output power unchanged, the volume and weight of the motor can be reduced, thereby improving the power density of the motor. In order to prevent the rotor in the motor from being damaged due to centrifugal force when rotating at high speed, a layer of carbon fiber rotor sleeve can be added to the outside of the rotor to protect the rotor.

[0003] At present, the common carbon fiber winding is to attach the magnetic steel to the surface of the rotating shaft, and then wind the carbon fiber rope or carbon fiber cloth strip coated with viscose on the circumferential surface formed by the magnetic steel. After the carbon fiber rope or carbon fiber cloth strip is wound, it is easy to have uneven local surface thickness and produce imbalance. Carbon fiber cloth is a high-performance composite material with the advantages of light weight, high strength, high stiffness, wear resistance, corrosion resistance and good high temperature performance. After the carbon fiber cloth is processed, a feeding device is needed to feed the carbon fiber cloth. When a feeding roller completes feeding the carbon fiber cloth, a new feeding roller needs to be replaced for subsequent feeding work. At present, it is relatively cumbersome to replace the feeding roller. The carbon fiber cloth needs to be cut, and then the cut part of the carbon fiber cloth is fixed on the new feeding roller, and the new feeding roller is installed. The downtime caused by replacing the feeding roller is long, and it is inconvenient to wind multiple carbon fiber layers, thereby reducing the feeding efficiency of the carbon fiber cloth. Therefore, it is necessary to provide a carbon fiber transverse feeding detection device to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a motor rotor winding carbon fiber feeding device in view of the deficiencies in the prior art. The servo-driven carbon fiber feeding device is adopted. The carbon fiber feeding is driven by a forward frame and a transverse mechanism. A heating component and a visual inspection head are configured. The structure is compact and reasonable, and it is not easy to cause damage to the carbon fiber. The carbon fiber feeding has high precision and strong adaptability, which improves the efficiency and quality of the feeding process before carbon fiber winding and has high safety.

[0005] The objective of the present invention is achieved through the following technical scheme: a carbon fiber transverse feeding detection device comprises a support plate and a transverse mechanism installed on the support plate, a forward frame is installed on the transverse mechanism, and a carbon fiber mounting frame, a tensioning roller group, a feeding roller, a tension sensing roller and a driving roller group are arranged on the forward frame, the mounting frame is connected to the brake, a compaction roller is arranged below the driving roller group, a heating assembly is installed in front of the driving roller group, a cutting knife assembly is arranged behind the heating assembly, a detection and adjustment frame is also installed on the forward frame, a visual detection head is installed on the detection and adjustment frame, and a visual controller is also installed on the forward frame. The carbon fiber is manually placed on the mounting frame, and the carbon fiber strips are installed in the order of the tensioning roller group, the feeding roller, the tension sensing roller and the driving roller group, the heating assembly and the compacting roller. The forward frame is driven by a servo motor to position and cooperate with the carbon fiber winding device with the rotor installed. After being heated by the heating assembly, the carbon fiber strips are wound around the rotor. When the end of the carbon fiber is first wound around the rotor, the compacting roller can directly contact the area of ​​the rotor where the carbon fiber is wound, thereby pressing the carbon fiber wound around the rotor onto the rotor, that is, pressing the end of the carbon fiber film onto the rotor. The compacting roller and the rotor driven by the winding device roll toward each other, thereby winding the carbon fiber strips around the rotor and driving the reciprocating motion through the transverse movement mechanism. The rotor surface is evenly wound with multiple layers of carbon fiber, and the carbon fiber strips are cut by the cutter assembly. The carbon fiber will not fall off the rotor, which improves the effect of winding multiple layers of carbon fiber layers. At the same time, when winding multiple layers of carbon fiber layers, a layer will be formed after one circle of carbon fiber winding, and the multiple layers of carbon fiber winding can be moved back and forth on the rotor to improve the winding efficiency; at the same time, when the carbon fiber membranes between adjacent layers are in contact, they will be stacked in sequence along the rotation direction of the carbon fiber membranes. Therefore, when winding, the gas between the adjacent carbon fiber membranes can be accumulated to the outside along the openings between the adjacent carbon fiber membranes, so that no bubbles will be generated between the formed carbon fiber layers, thereby improving the winding effect of the carbon fiber membrane and better protecting the rotor. The side image of the rotor is collected in real time by the visual inspection head, and the side image is sent to the processor. The processor analyzes the image to obtain the diameter D of the rotor after the carbon fiber cloth is wound. According to the diameter D and the speed of the rotating rotor servo motor, the speed of the servo motor of the driving roller group is adjusted. The labor intensity is low, and the product quality is greatly improved. The rotor wrapped with carbon fiber can be automatically output by the manipulator, which is convenient for connection with the previous and next processes.

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

[0007] Preferably, a visual inspection head is provided on the inspection and adjustment frame, and the visual inspection head can collect a side image of the rotor in real time and send the side image to a processor. The processor analyzes the image to obtain a diameter D of the rotor after the carbon fiber cloth is wrapped, and adjusts the speed of the servo motor of the driving roller group according to the diameter D and the speed of the servo motor rotating the rotor.

[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 in conjunction with the heating component.

[0009] The beneficial effects of the present invention are as follows: (1) the motor rotor winding carbon fiber feeding device is a servo-driven carbon fiber feeding device, which drives the carbon fiber feeding by a forward frame and a transverse mechanism, is equipped with a heating component and a visual inspection head, and can move back and forth multiple layers of wound carbon fiber on the rotor to improve winding efficiency and product quality; (2) the surface of the heating component is provided with an anti-stick coating. Since the carbon fiber cloth strip needs to be heated at the heating component, by providing an anti-stick coating on the surface of the heating component, the carbon fiber film will not adhere to the heating component when moving, making the movement of the carbon fiber film 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 be ensured that the carbon fiber film will not wrinkle when moving, avoid the formation of bubbles between the wound carbon fiber layers, and improve the product quality of the carbon fiber rotor.
