| 摘 要： | 激光器的打标速度、频率、填充间隔、电流、离焦量等工艺参数直接影响空气开关的打标效果。实验根据5因素4水平正交表L16(45)改变激光工艺参数，利用分光测色计和二维码扫描器对激光标记分别进行色差和读码率的测量，通过正交分析法和极差法研究激光工艺参数对打标效果的影响。研究表明:色差与读码率的数据趋于正比关系，并且存在一个阈值色差；当激光参数的速度为1 000 mm/s、频率为20~30 kHz、填充间隔为0.04 mm、电流为28 A、离焦量为-1 mm时，在空气开关上打标出点密度合适、色差对比度高、易于读取的二维码。 |

| Abstract: | The quality of two dimensional codes on air circuit breakers depends on laser parameters such as scanning speed, Q frequency, line spacing, electric current and defocusing distance. The experiment changed laser parameters according to the orthogonal table L16(45). Color difference was measured by a spectrophotometer and code success ratio was tested by a bar code scanner. Orthogonal analysis and range analysis were carried out to study the influence of laser parameters on marking effect. The experiment shows that, there is a threshold color difference and the linear relationship between color difference and code success ratio is good. Perfect two dimensional codes are obtained with optimum laser parameters, which are 1 000 mm/s scanning speed, 20 30 kHz Q frequency, 0.04 mm line spacing, 28 A electric current and -1 mm defocusing distance. |
