Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber quality inspection devices, specifically a visual positioning fixture for inspecting the quality of carbon fiber layup. Background Technology

[0002] In aerospace, high-end equipment manufacturing, and other fields, carbon fiber composite materials have been widely used due to their superior properties such as high strength and lightweight. The molding quality of carbon fiber composite components largely depends on the precision of the layup process. Defects such as wrinkles, misalignments, and overlaps that occur during layup can severely affect the mechanical properties and service life of the components. Therefore, the inspection of carbon fiber layup quality is crucial. Currently, carbon fiber layup quality inspection relies heavily on manual visual inspection or traditional mechanical positioning inspection methods. Manual visual inspection is not only inefficient but also heavily influenced by the experience and subjective factors of the inspectors, easily leading to missed or false detections. Traditional mechanical positioning inspection suffers from limited positioning accuracy, poor adaptability to complex curved surfaces, and the potential to damage the layup surface, making it difficult to meet the demands for high-precision and high-efficiency inspection. To improve the accuracy and efficiency of carbon fiber layup quality inspection and achieve rapid identification and location of layup defects, there is an urgent need for an auxiliary inspection device capable of accurately locating the layup area and adapting to complex component shapes. Visual positioning technology, with its advantages of non-contact operation, high precision, and rich information, has become an important approach to solving this problem. Against this backdrop, visual positioning fixtures for carbon fiber layup quality inspection have emerged.

[0003] Application number CN202320622111.0 discloses a positionable inspection fixture, belonging to the field of positioning and inspection technology. It includes a base, a control box fixedly mounted on top of the base with screws, a cylinder fixedly mounted on the side wall of a cylinder fixing block with screws, and a drive clamping device one connected to the end of the cylinder rod. The drive clamping device one includes a drive block with a guide and limiting groove at the bottom and a rack plate on the side wall. A fixed rotating assembly is fixedly mounted on the top of the drive block with screws. A drive clamping device two, with the same structure as the drive clamping device one, is located on the left side of the placement plate. The cylinder and the fixed rotating assembly are electrically connected to the control box. It can effectively limit and fix automotive parts of various sizes, and can also adjust their angles for better multi-faceted inspection, increasing inspection efficiency and effectively preventing damage to automotive parts due to excessive clamping force. However, a shortcoming is that the device lacks support for transferring inspected materials, making material transportation after inspection time-consuming and labor-intensive.

In the workflow, the fixture is placed in a suitable working position to ensure that the mounting base plate 101 is stably fixed.
