Wear detection system and method for grinding head

Abstract

The invention provides a wear detection system, which comprises a grinding head. The system further comprises a model construction module used for constructing a to-be-detected grinding head model andconducting region division on the surface of the grinding head according to the to-be-detected grinding head model to obtain region division position information. The image and information determination module is used for acquiring an image group of the grinding head according to the locking state of the grinding head and the grinding head model to be detected, and determining region division position information corresponding to each input image in the image group; the image abrasion identification module is used for carrying out image identification on the image group to obtain an abraded grinding head surface image, and dividing position information according to a region corresponding to the abraded grinding head surface image to obtain abrasion position information; and the wear evaluation module is used for generating a damage detection report according to the wear position information. Whether the grinding head is in a good using state or not can be detected. The grinding head can be replaced or maintained in real time according to monitoring conditions, and then the machining quality of plates is improved.

Description

technical field

[0001] The invention relates to the field of wear detection, in particular to a wear detection system and detection method for a grinding head. Background technique

[0002] Grinding head is a general term for a small grinding tool with a handle. It is used in electric grinders, hanging grinders, and electric hand drills. The important functional parts in the process, if the grinding head is damaged or scrapped, the products in the grinding process will need to be reprocessed or the grinding process time will be extended, and in the modern process, when there is a problem with the grinding device , It often requires staff to check one by one, which is extremely time-consuming, thereby reducing the production efficiency of the production process.

[0003] In addition, after a large number of searches, it was found that some typical prior art, such as patent CN107817186A, provides a detection system for accurately measuring mold wear, including a detection pla...
