On-line quality detection system of button cell

Abstract

The invention belongs to a field of product quality detection, and especially relates to an on-line quality detection system of a button cell. The invention aims to provide the on-line quality detection system with good precision and high efficiency of the button cell. The detection system comprises a lower computer system and an upper computer system which are in communication connection through a system integration module, wherein the lower computer system comprises a current and voltage detection module comprising a metal probe module for connecting the to-be-tested button cell, a CPU module and an attached sensor module, and a machine vision detection module comprising an image acquisition module and an image processing module, the image acquisition module is composed of a light source, an industrial camera and lens, and the image processing module realizes analysis, processing, wavelet analysis, feature extraction, template coupling and defect detection for the acquired images.

Description

technical field [0001] The invention belongs to the field of product quality detection, in particular to an online quality detection system for button batteries. Background technique [0002] Button battery, also known as button battery, refers to a battery that looks like a small button. Generally speaking, it has a larger diameter and a thinner thickness (compared to cylindrical batteries such as AA batteries on the market). Button batteries are distinguished from the shape, and the corresponding battery classifications include cylindrical batteries, square batteries, and special-shaped batteries. Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable. The more common button batteries are AG3, AG10, and AG13 batteries used in toys and gifts, and CMOS batteries on computer motherboards. [0003] Button battery is widely used in various miniature electronic products because of its small size. Its appearance is made of stainless steel,...

AI Technical Summary

Problems solved by technology

[0004] The use of button batteries determines that the quality inspection requirements are higher. At present, manual inspection methods have gradually failed to meet the efficiency requirements of modern manufacturing industries.

Detection based on machine vision is becoming a research hotspot in the field of machine vision, in order to overcome the problems of slow detection speed, inconsistent accuracy, and large labor load caused by traditional manual detection methods.
