An infinitely rotating camera and its method, and a visual inspection system for cold-rolled steel strip

Abstract

The invention discloses a stepless rotating camera head. The lens is fixedly connected to the stepless turning ball, which can rotate clockwise and counterclockwise along the x-axis direction. The stepless turning box is provided with a driving device for the stepless turning ball. The working method includes: turning on the main rotating wheel of the motor to drive the rotating wheel and the screw to rotate. The cold-rolled steel strip vision inspection system includes a camera. The camera can maintain infinite rotation in a limited space, which removes the restriction of its rotation in a limited space, and can realize fine-tuning of the shooting angle of the camera, so as to ensure the seamless quality inspection of cold-rolled steel plate welds and expand the inspection field of view. And only one motor is used for control, which greatly saves the number of motors used compared with the prior art, thereby reducing more energy consumption and being more environmentally friendly. In addition, the overall structure of the present invention is simple and compact, and because only one motor is used, the occupied space is small, and the problem of limited space can be solved.

Description

technical field [0001] The invention relates to a visual detection device and a steel strip visual detection system, in particular to an infinitely rotating camera and method and a cold-rolled steel strip visual detection system. Background technique [0002] Weld quality is one of the factors that determine whether there is a probability of strip breakage in the continuous rolling production process of strip steel. In order to avoid the occurrence of weld defects, most domestic steel mills have invested a lot of money to promote improvement. However, due to lack of mature application experience, after improvement play a very limited role. At present, major domestic steel mills are working to improve labor efficiency, and weld quality inspection has become an urgent need for workshops. The pilot is successful and can be expanded to other production lines. [0003] However, in order to effectively detect the quality of the weld seam by taking pictures and sampling images, th...

Problems solved by technology

[0003] However, in order to effectively detect the quality of the weld seam by taking pictures and sampling images, three major problems have been encountered: limited camera space, insufficient field of view for image detection, and difficulty in fine-tuning the camera shooting angle. These three major problems make weld image detection always flawed.
