摘要
针对目前电子式健康秤采用人工检定存在的劳动强度大、工作效率低和工人易出错等问题,开发了基于机器视觉的自动检定系统。利用机器视觉系统进行LCD显示屏字符识别、误差计算和结果判定;通过伺服电缸进行增砣砝码的逐级加载和卸载;采用气缸实现检测产品的送料和退料。结果表明:视觉系统可实现LCD字符的精确快速识别,检定系统可完成电子式健康秤的自动计量检定,具有高效、高精和智能等特点。
To solve high labor intensity, low work efficiency and error-prone problems in the manual verification process of electronic personal scales, an automatic verification system based on machine vision was developed. The LCD display screen＇s character recognition, error calculation and result determination are conducted by means of machine vision. The step by step loading and unloading of weight-increasing weights are done by linear actuator driven by servo motor. The feeding and returning of products are carried out by air cylinder. The results show that the vision system can realize exact and fast recognition for the LCD characters and the verification system can be competent for the automatic metrological verification for electronic personal scales, with characteristics of high efficiency, high precision and intelligence.
