Problems solved by technology
However, the current machine vision inspection system uses a single camera to detect defects, and can only target panels with fixed positions. The accuracy is not high, the accuracy rate is low, the flexibility is poor, and the inspection time is long, which cannot meet the actual production capacity requirements of the manufacturer's production line.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0026] Such as figure 1 , figure 2 As shown, the present invention is based on a high-precision automatic optical detection system of a robotic arm, including a robotic arm, a surface scanning module, an image processing module and a system control module, wherein:
[0027] The mechanical arm is used to adjust the position of the surface scanning module according to the control signal of the system control module, so that the camera in the surface scanning module is aligned in parallel with the module to be tested, positioned front and rear, and aligned left and right. The specific adjustment process is described below.
[0028] The surface scanning module is installed on the robotic arm, including laser, multiple cameras and mo...

A high-precision automatic optical detection system and method based on a mechanical arm. The detection process comprises: adjusting the position of a line-by-line scanning module by means of a mechanical arm, so that the line-by-line scanning module is automatically aligned with a module to be detected; and controlling various cameras to detect the module to be detected, and displaying a detection result on a display interface. By means of the mechanical arm and an electric motor, parallel alignment of a plurality of cameras and a module is achieved quickly, thereby guaranteeing that the cameras can efficiently and accurately take photographs, improving detection efficiency, and saving on detection time. The arrangement of the plurality of cameras can be flexibly adapted to the detection of modules of different sizes, thereby guaranteeing detection precision and accuracy.
Description
technical field [0001] The invention belongs to the technical field of automatic optical detection of LCD liquid crystal modules, and in particular relates to a high-precision automatic optical detection system and method based on a mechanical arm. Background technique [0002] In recent years, due to the light and thin characteristics of LCD (Liquid Crystal Display), it has been used in most communication products (such as car navigation systems, mobile phones), consumer electronics products (such as LCD TVs, video cameras) ), instrument products and industrial automation products and other fields, all use LCD as the control panel, and its application range is very wide. Since the entire LCD production process is long, and the size of the substrate is getting larger and the size of the circuit is getting more and more precise, therefore, strict quality control is required in the production process of the LCD. The traditional LCD inspection method is mainly through manual i...
