Detection sorting device for steel balls

Abstract

The invention relates to a detection sorting device for steel balls The detection sorting device comprises a rack, a feed mechanism, an unfolding mechanism, a stock stop, a detecting mechanism, a sorting mechanism and a material collecting mechanism, wherein the feed mechanism comprises a material storing box, a material discharging hopper and a material discharging pipe; the unfolding mechanism comprises a material transporting guide rail, the material transporting guide rail is a V-shaped linear guide rail, the material discharging hopper is connected with an initiating end of the material transporting guide rail through the material discharging pipe, and the detecting mechanism comprises a light source assembly and a camera assembly; the light source assembly is arranged on the material transporting guide rail in a sleeved mode, the sorting mechanism and the material collecting mechanism are arranged on the tail end of the material transporting guide rail, and the separate collection of defect steel balls and qualified steel balls are realized through the sorting mechanism and the material collecting mechanism. The detection sorting device provided by the invention has the advantages that the automatic feed, detection and sorting of the steel balls are realized, a detection process is that two-dimensional motion of a traditional unfolding disc is changed into single one-dimensional rolling of one-sided steel balls, the detection efficiency is high, a false drop ratio and an omission ratio are low, and the steel balls are not magnetized or the surfaces of the steel balls are not damaged in a 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...

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
