Technical Field

[0002] A carbon fiber bicycle frame is a bicycle frame made of carbon fiber material, which has the advantages of light weight, high strength and good corrosion resistance. Carbon fiber bicycle frames require bonding during the manufacturing process. Carbon fiber bicycle frames, front forks, wheels and other components are usually bonded using special carbon fiber glue during the manufacturing process.

[0003] For example, the Chinese authorized patent with announcement number CN213566309U (a carbon fiber bicycle frame bonding device) includes a device body, a screw rod is provided on both sides of the top of the device body, a movable splint is provided at both ends of the outer side of the screw rod, a support seat is provided at the top of the device body, a mounting plate is provided on both sides of the top of the device body, a hydraulic cylinder is provided on one side of the mounting plate, a support rod is provided on the inner wall of the mounting plate, and a curved plate is provided on one side of the support rod. The utility model is provided with a movable splint, a mounting plate and a curved plate. The curved plate can clamp and fix the frame under the elastic force of the support spring. At the same time, the servo motor can drive the two movable splints to clamp the frame. Then, the hydraulic cylinder can drive the mounting plate to move, so that the two frames can be bonded together. At the same time, the movable splint can limit the movement of the frame, which can ensure the stability of the frame during bonding.

[0004] However, when bonding existing carbon fiber bicycle frames, the frames need to be adjusted in angle from the beginning and then fixed with a clamp. This requires multiple tightening and loosening to adjust the angle, which is time-consuming and labor-intensive and has poor flexibility. Therefore, this method does not meet existing needs. To address this issue, we propose a carbon fiber bicycle frame bonding device. Utility Model Content
