3D Machine Vision Inspection System Superior Defect Detection for Gears

Product background

The function of the gear is to transmit the rotation of one shaft to another shaft, and it can also realize actions such as deceleration, acceleration, direction change and reversal. A gear is a mechanical element that continuously meshes with gears on the rim to transmit motion and power. The application of gears in transmission appeared very early. The principle of the generating gear cutting method and the special machine tools and tools that use this principle to cut teeth have appeared one after another. With the development of production, the stability of gear operation has been paid attention to.

As a universal mechanical part, the precision of gear has an important influence on the performance of mechanical products. Improving gear detection technology is the guarantee for improving the quality of gear products. Due to the characteristics of gear shape, there are many detection items, complex measurement process, and expensive measurement equipment. Machine vision inspection is a non-contact non-destructive inspection, which has great advantages compared with traditional inspection methods.

Inspection principle

When the product is imaged on the background plate, it is processed by a special light source to obtain a clear image, and then analyzed by the image processing pattern recognition algorithm to obtain the result. The gear machine vision inspection system is mainly supported by industrial cameras, industrial lenses, and vision processing software. First, a CCD industrial camera connected to a computer is used to complete the image acquisition task, and the captured target is converted into an image signal.

Using the principle of visual detection of visible objects, industrial cameras are used to convert the detected target into an image signal, and according to the pixel distribution, brightness, color and other information, it is converted into a digital signal. The image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, size,etc., by analyzing the image of the sample to obtain various parameters and standard products for real-time AI analysis, reject unqualified samples through compressed air, and automatically count qualified samples, to improve production efficiency.
