Method and device for unfolding steel ball surface based on multi-image sensor

Abstract

The invention relates to a method and a device for unfolding the surface of a steel ball on the basis of multiple image sensors. In the method, a linear guide rail is provided; the linear guide rail has gradient; two symmetrical image sensors with the same structure are arranged above two sides of the axis of the linear guide rail respectively and are used for adjusting two image sensor parameters and two camera lens optical parameters to be consistent; the tested steel ball is arranged on the linear guide rail with a groove; the tested steel ball does one-dimensional motion along the linear guide rail with the groove under the force gravity; and when the tested steel ball passes through the downsides of the image sensors, the two image sensors perform continuous image sampling on the tested steel ball. The device comprises the linear guide rail, two brackets and two image sensors, wherein the linear guide rail has gradient and is formed by the groove and arranged in the middle of a workbench; the two brackets are symmetrically arranged at two ends of the workbench and positioned on two sides of the linear guide rail; the top ends of the two brackets are provided with one image sensor respectively; and the camera lenses of the two image sensors correspond to the central axis of the bottom of the linear guide rail. By the method and the device, the surface of the steel ball canbe unfolded at high speed and precisely.

Description

technical field [0001] The invention relates to a steel ball surface unfolding method. In particular, it relates to a multi-image sensor-based steel ball surface unfolding method and device that can achieve full coverage of the ball surface only by one-dimensional rolling of the steel ball. Background technique [0002] Whether it is used as a component of a bearing or as an independent rolling element, steel balls are widely used. Due to processing technology and precision, during the manufacturing process, defects such as wear, cracking, rust, and pits will appear on the surface of the steel ball. These defects have a decisive impact on the performance of the bearing such as speed, noise, vibration, and life. Therefore, the detection of steel ball surface defects is of great significance. [0003] At present, most domestic manufacturers use artificial methods, that is, to check the surface quality of steel balls with the naked eye or with the help of a low-power magnifyi...

Problems solved by technology

And it is this that causes the randomness and complexity of obtaining full-coverage images of the steel ball surface

[0006] Therefore, the deployment device of the steel ball still has the following problems: 1. Almost all stay in two-dimensional motion, and the mechanical structure is complicated

2. Cannot achieve full coverage

However, the image obtained by this method is random, and it cannot guarantee to completely cover the surface of the steel ball, and the mechanism is relatively complicated.
