Roll-over stand suitable for carbon fiber plate image scanning detection

Abstract

The invention relates to a roll-over stand. Since an upper clamping module and a lower clamping module are used for clamping a carbon fiber plate and each of the upper clamping module and the lower clamping module comprises a detachable sliding support plate, the carbon fiber plates can be supported by supporting plates, so that deformation of the carbon fiber plates during detection is avoided; marking points of the same reference plate are innovatively used as reference points and thus marking point data shot before overturning and marking point data shot after overturning can be merged intothe marking point data of the same coordinate system after certain coordinate conversion, so that complete carbon fiber plate front-back springback amount data are obtained, and subsequent processingof the data is facilitated.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a flip frame adapted to scan and detect images of carbon fiber plates. Background technique [0002] Carbon fiber composite materials have excellent mechanical properties, and they have the advantages of high strength, high modulus, high specific strength and high specific modulus. As a carbon fiber composite material, carbon fiber sheets have always been sought after by people. Since the molding of the carbon fiber board is usually performed by means of compression molding, the springback of the front and back of the carbon fiber board will be different. A detection device and method for detecting both front and back sides. Even taking into account the difference in the amount of springback on the front and back of the carbon fiber board, the general practice is to fix the carbon fiber board on a bracket, and then use an image scanner to capture the front and back i...

Problems solved by technology

Even taking into account the difference in springback between the front and back of the carbon fiber board, the general practice is to fix the carbon fiber board on a bracket, and then use an image scanner to take the front and back images of the carbon fiber board fixed on the bracket, and then build a carbon fiber board. However, since the carbon fiber board must be fixed firmly when detecting the springback of the front and back sides of the carbon fiber board, it is necessary to set a support point at the bottom of the carbon fiber board, and after setting the support point, use an image scanner. When scanning, there must be dead spots that cannot be scanned. Therefore, using this method has the disadvantage of inaccurate models

[0003] To sum up, in the prior art, none of the image scanners provides an image scanner that takes photos of the surface of the carbon fiber plate from the top surface, and the carbon fiber plate itself rotates, thereby collecting an image of the carbon fiber plate that adapts to the springback of the front and back sides of the carbon fiber plate. The flip frame for scanning inspection, which can support the carbon fiber board stably and at the same time, can shoot the front and back of the carbon fiber board from the top surface without dead spots, improving the detection accuracy
