Abstract

The embodiment of the invention discloses a detection method and system for micro bar materials. The method comprises the steps that a feeding system conveys the micro bar materials to be detected to a before-jumping carrying system; the before-jumping carrying system conveys the micro bar materials to a jumping detection system; the jumping detection system carries out jumping detection on the micro bar materials, and a jumping detection result is obtained; a cylindrical detection system carries out cylindrical detection on the micro bar materials obtained after jumping classifying, and a cylindrical detection result is obtained; and a defective-product sorting system carries out classified statistic on the detected micro bar materials according to the jumping detection result and the cylindrical detection result. According to the method and system, precision and repeat reliability of the detection result can be improved; in addition, the detection efficiency can be improved, different kinds of failed test samples can be subject to classified statistic, the problems that in the prior art, when manual detection is adopted, the false drop rate is high, the yield is low, and detection reliability is low are solved, and the problem that in the prior art, surface defective detection cannot be carried out on the micro bar materials can also be solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection method and system for a micro-rod. Background technique [0002] Micro rods, referred to as micro rods, have a diameter of less than 10mm. Micro rods are pressed from tungsten steel powder and are raw materials for making printed circuit board (Printed Circuit Board, PCB) drills, milling cutters and other tools. The quality of micro rods determines the yield of back-end products. [0003] The existing domestic enterprises currently use manual inspection for micro-bars. For this reason, the inspection post is equipped with a large number of inspectors, and the proficiency and accuracy of the inspectors are completely relied on to ensure the detection efficiency and the accuracy of the final delivery of qualified products. However, the efficiency of manual detection is low and there are unavoidable false detections, missed detections and false detections, which often...
