A steel ball detection device and a steel ball detection method using the device

Abstract

A steel ball detection device is disclosed. The device is provided with a steel ball automatic feeding apparatus, a steel ball surface fully-expanding apparatus and a vision sensing system. Under control of an image processing system and through recognizing surface defects of the steel balls, the device automatically detects surface quality of steel balls and automatically separates qualified products from unqualified products. The device is mechanized in operation and high in the percent of pass of detection, ensures the detection efficiency and reduces the omission ratio. The invention also discloses a steel ball detection method using the steel ball detection device. Steel ball detection is finished by using the steel ball detection device through above-mentioned steps. The method is high in working efficiency and reduces the omission rate. A defect that steel balls rub and collide with each other in a manual detection process in the prior art so that artificial damages occur and the reject ratio of the steel balls is increased is overcome by the device and the method.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and more specifically, the invention relates to a steel ball detection device and a method for using the device to detect steel balls. Background technique [0002] The steel ball is the main component of the bearing. The quality of the steel ball directly affects the quality of the bearing. The steel ball is produced by equipment and has a large output. However, the inspection of the steel ball in the prior art is done manually. A large number of tiny steel balls, Relying on manual sorting one by one, the workload is very heavy. This inspection method is not only inefficient, but also has a high rate of missed inspections; in the process of manual inspection, a large number of steel balls are packed in containers and dumped on the inspection table The sorting method is completed. In this working method, the steel balls rub against each other, causing artificial damage, increasin...

[0002] The steel ball is the main component of the bearing. The quality of the steel ball directly affects the quality of the bearing. The steel ball is produced by equipment and has a large output. However, the inspection of the steel ball in the prior art is done manually. A large number of tiny steel balls, Relying on manual sorting one by one, the workload is very heavy. This inspection method is not only inefficient, but also has a high rate of missed inspections; in the process of manual inspection, a large number of steel balls are packed in containers and dumped on the inspection table The sorting method is completed. In this working method, the steel balls rub against each other, causing man-made damage, increasing the failure rate of the steel balls, and artificially increasing the production cost.
