Embodiment 1

[0033] like Figure 9 As shown, the embodiment of the present invention provides an online mobile monitoring mechanism for metal additive manufacturing, including a mobile platform 4 and a CCD camera 5. The mobile platform 4 is used to drive the CCD camera 5 to move, and the CCD camera 5 is used to collect online laser selective melting manufacturing. Process part surface image. Institutions also include Figure 1-6 The shown clamp assembly for clamping the CCD camera 5 and fixing it on the mobile platform 4 includes a shovel clamp 1 , a sleeve clamp 2 and a grapple clamp 3 . The shovel-shaped clamp 1 is mainly aimed at the light weight of the CCD camera 5, and is used for clamping the CCD camera 5 whose weight is within the range of 1.5kg-4.0kg. The sleeve-type fixture 2 is mainly aimed at the moderate weight of the CCD camera 5, and is used to clamp the CCD camera 5 with a weight in the range of 4.0kg to 9.0kg. The sleeve-type fixture 2 is screwed and fixed. The section i...

Embodiment 2

[0041] like Figure 10 As shown, the embodiment of the present invention also provides an online appearance inspection device for metal additive manufacturing, which includes the online mobile monitoring mechanism for metal additive manufacturing in the above-mentioned embodiment 1, and also includes an image processing system and a working system. The image processing system uses Based on the molten pool and sputtering images collected by the CCD camera of the online mobile monitoring mechanism, the defect area is accurately positioned and identified, and the results are fed back to the working system, which is used to adjust the 3D printing process according to the information fed back by the image processing system. Process parameters to produce high-quality defect-free parts.

[0042] Specifically, the image processing system includes an image preprocessing module, a generative adversarial neural network (Generative Adversarial Network, GAN) module, and an LBP (Local Binar...

Abstract

The invention provides an online mobile monitoring mechanism and online appearance inspection equipment for metal additive manufacturing. The online mobile monitoring mechanism includes a mobile platform and a CCD camera, and also includes a clamp assembly for clamping the CCD camera and fixing it to the mobile platform. , the clamp assembly includes a shovel clamp, a sleeve clamp and a grapple clamp, the shovel clamp is used to clamp a CCD camera with a weight in the range of 1.5kg to 4.0kg, and the sleeve clamp is used for CCD cameras with a weight ranging from 4.0kg to 9.0kg are clamped, and the grapple-type clamp is used to clamp a CCD camera with a weight of more than 9kg. The present invention includes a variety of different clamps. For CCD cameras of different weights, different clamps can be selected for clamping, so as to achieve full coverage of CCD cameras of various volumes and weights, and can effectively clamp various CCD cameras on the market. It is held and fixed, has high stability, and is convenient for taking high-precision metal additive manufacturing images, and meets the image accuracy requirements of various online appearance inspection methods.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to an online mobile monitoring mechanism and online appearance inspection equipment for metal additive manufacturing. Background technique [0002] Metal additive manufacturing is a new type of laser rapid prototyping manufacturing process, which is a kind of additive manufacturing. It can directly form metal parts with close to complete density and good mechanical properties. Therefore, this technology has great potential and has shown good application prospects in aerospace, automobile, biomedical and other fields. However, in the metal additive manufacturing process, due to the influence of laser power density, scanning speed and other process parameters, defects (such as cracks, holes, etc.) may appear in the formation process of parts. Therefore, the defects in the metal additive manufacturing process There is an increasing demand for online diagnostic devices. [0003]...
