Automatic detection device and method for roller surface of roller press

Abstract

The invention discloses an automatic detection device and method for the roller surface of a roller press, and can solve the technical problem that an existing detection device is low in detection precision. The device comprises a shooting control module, a motion execution module and a data processing module; the shooting control module comprises an industrial linear array camera, a motion controller and a local computer; the industrial linear array camera is arranged above the roller surface of the roller press; the local computer is in communication connection with an industrial line-scan digital camera and is used for setting shooting parameters of the industrial line-scan digital camera and receiving pictures shot by the industrial line-scan digital camera. According to the invention,the industrial line-scan camera scans the roller surface to obtain a local picture of the roller surface, and the shooting position of the industrial line-scan camera is changed to obtain a pluralityof local pictures of the roller surface; local roll surface photos are cut and spliced to obtain point cloud data of a complete roll surface, a roll surface two-dimensional model and a roll surface three-dimensional model are established according to the point cloud data, roll surface defects are detected, and a database system is established to manage different roll surfaces. Therefore, the expansibility is good, the automation degree is high, and the detection precision is high.

Description

technical field [0001] The invention relates to the technical field of industrial automatic detection, in particular to an automatic detection device and a detection method for a roller surface of a roller press. Background technique [0002] Roller press is a large-scale engineering equipment used to squeeze and crush materials, and is widely used in cement, mining, chemical and other industries. It works as figure 1 Shown: Feeding is carried out from the top of the equipment, and the material is crushed under high pressure by two horizontally installed and synchronously rotating extrusion rollers. As the material layer is forced to move downward, the extrusion force gradually increases enough until it is crushed and extruded into a compact cake that is discharged from under the rollers. [0003] Due to the high crushing pressure of the roller press, the equipment will also be worn simultaneously while crushing efficiently. figure 2 It shows the common defects of the ro...
