Abstract

The invention provides a thimble surface defect video detection sorting device. The device comprises a frame, a thimble conveying mechanism, a waste needle suction conveying mechanism, a segmented program-controlled ring lamp, a program automatic controller and an industrial personal computer. The program automatic controller is connected to the thimble conveying mechanism, the waste needle suction conveying mechanism, and the segmented program-controlled ring lamp. A camera mechanism comprises three cameras which are in a first plane and form a120 degree included angle. The industrial personal computer is connected to the cameras and the program automatic controller. The invention also provides a thimble surface defect video detection sorting method. The device and the method have advantages that judgment is rapid and accuracy is high; and damages to the thimbles to be detected are reduced, the three cameras are used to take pictures according to the120 degree angle, which can achievefull coverage without dead angles, and a better identification result can be realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the fields of computer vision technology and automatic control technology, in particular to a video detection and sorting device and a sorting method for thimble surface defects. [0003] 【Background technique】 [0004] The company needs to automate the quality inspection link of a tiny accessory "thimble" product on the LED lamp bead production equipment, mainly to solve the automatic sorting of defective products and good products. The surface of the good products processed by the "thimble" from the machine tool is smooth, the slope is 9.6°-10.4°, the bottom is flat, the length is 17.0-17.02mm, and the R angle is full. Defective products have broken tips, broken edges, uneven bottom, flat, different lengths, rough tips, etc. The reasons for the above defects are: rough grinding and broken tips in machine tool processing, excessive rough machining wear; finishing wear Too much; when cutting the length of the thimble, ...
