Problems solved by technology
Hot air heating has the problems of small heating space and low energy utilization rate; infrared heat source heating has problems such as long heating time and difficult to accurately control the temperature field; laser heating has the characteristics of energy concentration and high heating efficiency, but according to laser The unique form of point source heating, in order to adapt to the uniformity of heat radiation along the width of the wide prepreg tape, requires an additional set of motion control mechanisms coordinated with the molding process, especially the at least two freedoms required in this mechanism. Degree of movement, the existing laying device rarely has a laser heating motion control mechanism

The invention relates to a tape laying device used for forming and manufacturing composite material prepreg tape, and belongs to the technical field of advanced composite material automatic manufacturing. It includes the main body of the device and is arranged on the main body of the device and arranged in sequence along the conveying path of the prepreg tape: an unwinding unit for placing the prepreg tape roll; a cutting unit for cutting the prepreg tape along the conveying direction of the prepreg tape Divided into several narrow belts; the feeding guide unit drives the prepreg belt forward through rollers and pressure wheels; the cutting unit cuts off the corresponding narrow belts at different positions and times according to the shape requirements of the laid mold; the backing belt The support unit is used to press the prepreg tape on the backing tape through the pressure bonding wheel; the rolling unit is supported on the bottom end of the backing tape to apply pressure to lay the prepreg tape on the surface of the mold. The whole device is small in size and light in weight, and can be installed at the end of the robotic arm for in-situ flexible production.
Description
technical field [0001] The invention relates to the technical field of automatic manufacturing of advanced composite materials, in particular to a tape laying device used for forming and manufacturing composite material prepreg tapes. Background technique [0002] Advanced composite materials refer to composite materials that can be used as main load-bearing structural parts and have higher strength and stiffness than aluminum alloys. Among them, the composite material with carbon fiber as the reinforcement matrix has been applied and promoted in the fields of medical equipment, transportation, and aerospace by virtue of its high specific strength and high temperature resistance. Therefore, the requirements for improving the manufacturing technology of composite materials are also in harmony with each other. [0003] Automatic lay-up technology is an additive manufacturing technology for advanced composite materials. Use an automatic laying device to lay a certain width of...
