A detection and sorting device for steel balls

Abstract

The invention relates to a detection and sorting device for steel balls, which includes a frame, a feeding mechanism, an unfolding mechanism, a blocking mechanism, a detection mechanism, a sorting mechanism and a receiving mechanism; the feeding mechanism includes a storage box, a lower The hopper and the feeding pipe, the unfolding mechanism includes a feeding guide rail, the feeding guide rail is a V-shaped linear guide rail, and the feeding hopper is connected to the starting end of the feeding guide rail through the feeding pipe; the detection mechanism includes a light source assembly and a camera assembly, and the light source assembly cover is set On the conveying guide rail, the sorting mechanism and receiving mechanism are arranged at the end of the conveying guide rail, and the defective steel balls and qualified steel balls can be collected separately through the sorting mechanism and receiving mechanism. The detection and sorting device of the present invention can realize automatic feeding, detection and sorting of steel balls, and the detection process changes from the two-dimensional movement of the traditional unfolding plate to the one-dimensional pure rolling of steel balls on one side, with high detection efficiency and no false detection The detection rate and missed detection rate are low, and the steel ball will not be magnetized or the surface of the steel ball will be damaged during the detection process.

Description

technical field [0001] The invention relates to the technical field of rolling body detection, in particular to a detection and sorting device for steel balls. Background technique [0002] Steel balls are widely used both as bearing balls and as general-purpose rolling elements. The surface quality of the steel ball directly affects the precision and service life of the bearing. At present, most of the domestic steel ball production enterprises adopt the traditional light inspection method, that is, the personnel manually move the steel ball in the flat shovel, observe it with the naked eye (or a low-power magnifying glass) under the light, and manually pick out the steel ball. defective ball. In the face of batch inspection requirements, the light inspection method is not only low in detection efficiency, but also cannot ensure that the ball surface is fully expanded by manual pushing, which is easy to miss or falsely detect, and at the same time causes great damage to t...

Problems solved by technology

The light source cover in the invention is bowl-shaped. Due to the shape of the bowl-shaped light source, the intensity of light at different positions in the bowl is uneven. The intensity of light at the edge is low, and the intensity of light has a greater impact on the shooting of the camera, which leads to an increased probability of errors in the detection results
