Mechanical arm-based 3D curved surface glass defect detection device and method

Abstract

The invention discloses a mechanical arm-based 3D curved surface glass defect detection device and method. The device comprises a support, wherein a mechanical arm, a stroboflash controller and a system controller are arranged on the support, and the system controller controls the mechanical arm and the stroboflash controller. According to the mechanical arm-based 3D curved surface glass defect detection device, the mechanical arm and an adsorption component are used for simulating human hands to grab, move and rotate 3D curved glass, the stroboflash controller, light sources and a line scanning camera are used for acquiring images of the inner and outer surfaces of the 3D curved glass under different light sources, then the images are analyzed through machine vision, glass defects recognizing by naked eyes is simulated, so that the problems that conventional glass detection equipment is poor in control precision and flexibility and can only detect 2D glass, for 3D curved or irregularplane glass, the detection effect is poor, the defect recognition rate is low, the misjudgment rate is high, a lot of artificial visual retaking appearance is required are solved.

Description

technical field [0001] The invention relates to the field of glass production and testing equipment, in particular to a device and method for detecting defects of 3D curved glass based on a mechanical arm. Background technique [0002] The robotic arm is a flexible and precise mechanical structure that imitates the human hand. It has an execution end that can move precisely on three coordinates in space. Through special position detection and power control, its precision and flexibility are intelligent enough to simulate The human hand, which realizes part of the functions of the human hand, has been more and more widely used in the field of industrial automation. In the field of 3D glass detection, due to the lack of control precision and flexibility of traditional detection equipment, it is impossible to make the distance between the imaging surface to be scanned and the camera on the 3D curved surface of 3D glass (object distance: the distance from the camera to the surfa...
