Embodiment Construction

[0018] This embodiment is a machine vision defect tracking and positioning system, which is installed on a production line machine and includes a PLC control unit, a visual inspection device, a light tracking mechanism, an encoder, and the like.

[0019] In this example, the PLC control unit circuit is connected to the control unit of the production line machine, and the production line machine can be controlled to stop by the control unit of the production line machine.

[0020] In this embodiment, the visual detection device has a camera and a data processing unit. The camera is set corresponding to the product on the production line machine, and is used to obtain the product image of the product on the production line machine. The data processing unit analyzes the product image according to the existing defect recognition algorithm. Identify and classify defects on products.

[0021] In this embodiment, according to the requirements of customers, different types of defects ...

Abstract

The invention relates to a machine vision flaw tracking and positioning system, which is arranged on a production line machine table and is characterized by comprising a control unit connected with a control unit of the production line machine table. a visual detection device in communication connection with the control unit and arranged corresponding to a product on the production line machine table; a light following mechanism in communication connection with the control unit, arranged corresponding to the product on the production line machine table, positioned at the downstream of the visual detection device along the product conveying direction, and provided with a plurality of indicator lights capable of illuminating different areas of the product in the breadth direction; and an encoder in communication connection with the control unit and mounted on a winding rotating shaft on the production line machine table. After receiving the position information of the flaws, the control unit is combined with the encoder to control the production line machine table to stop, so that the flawed area of the product on the production line machine table stops at the position corresponding to the light following mechanism, and the indicating lamp corresponding to the flawed area in the light following mechanism is controlled to illuminate the corresponding area according to the position information.

Description

technical field [0001] The invention relates to a machine vision defect tracking and positioning system. Applicable to the field of defect detection. Background technique [0002] At present, in the process of continuous roll defect detection in the field of machine vision, online shutdown processing cannot be realized for a certain defect or certain defects of specific requirements, such as marking of defects after shutdown, removal of defects, or viewing and confirmation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a machine vision defect tracking and positioning system for the above existing problems, so as to realize online shutdown processing of a certain defect or certain defects of specific requirements. [0004] The technical solution adopted in the present invention is: a machine vision defect tracking and positioning system, which is set on the production line machine, and is characterized in that ...
