Problems solved by technology

[0002] Advanced composite materials have the advantages of light weight, high strength, high modulus, fatigue resistance, corrosion resistance, designability and good manufacturability, and are widely used in aerospace and military fields. However, the forming equipment has complex structure and difficult control. The manufacturing cost is high, and composite material products are rarely used in the civilian field

specific Embodiment approach 1

[0069] Specific implementation mode one: combine figure 1 , 6 , 7, 8, and 9 illustrate the implementation of Embodiment 1. During the laying process of the fiber prepreg tape 3-5, the tension detection device 2 detects the tension of the tape during the laying process, the heating device 4 heats the fiber prepreg tape 3-5 to be laid or the laid surface, and the pressing roller device 5 Compact the prepreg tape 3-5 onto the heated mandrel or lay-up surface. Before the prepreg tape 3-5 enters the shearing device 3-2, the backing paper 9 is separated from the fiber tape 3-5, and passes through the fixing wheel 3-7 of the pressing device, the backing paper guide wheel 10, and the pressing roller 5-2 , and finally wound on the delivery roller 6-2.

specific Embodiment approach 2

[0070] Specific implementation plan two: combine figure 1 , 7 , 12, 13, and 14 illustrate the implementation of Embodiment 1. This embodiment is identical with embodiment one except shearing and compacting device. Before the prepreg tape 3-5 enters the shearing device 3-2, the pressing wheel first compresses the prepreg tape 3-5 to prevent the prepreg tape 3-5 from rebounding under tension after shearing. After entering the shearing device, the backing paper 9 and the fiber tape 3-5 are attached to the upper and lower sides of the wedge-shaped block 3-12 respectively, so that the backing paper is not cut off when being convenient to mechanical cutting. After the cutting is completed, the pressing wheel will compress the backing paper and the fiber tape again to ensure that the fiber tape is in the correct position relative to the backing paper and laid on the laying surface without deviation. Like this just can neither cut backing paper 9 and the normal delivery of the fibe...

Description

technical field [0001] This article relates to a six-axis robot-based automatic tape laying device and method in composite material laying equipment, which belongs to the technical field of composite material forming. Background technique [0002] Advanced composite materials have the advantages of light weight, high strength, high modulus, fatigue resistance, corrosion resistance, designability, and good manufacturability, and are widely used in aerospace and military fields, but their molding equipment is complex in structure and difficult to control. The manufacturing cost is high, and composite material products are rarely used in the civilian field. Therefore, the low-cost manufacturing technology of composite materials is the core issue in the field of composite materials in the world, and the automatic tape laying technology of composite materials is the research focus of low-cost manufacturing technology of composite materials. [0003] Automatic tape laying technol...
