本文采用半导体激光器进行掩模辅助激光传输,用透明的焊接剂对PET和PET进行微连接,掩模狭缝宽度为0.3 mm,利用CCD进行实验设计。采用响应面法建立了连接工艺参数与接头强度、接头宽度之间的数学模型。并进行了实验验证。将实际接缝宽度与掩模狭缝宽度进行了比较,优化了工艺参数。结果表明,建立的数学模型能较好地反映工艺参数与接头质量之间的关系,掩模能有效控制接头宽度,合理的工艺参数可获得高精度、高强度的接头质量。
This article uses semiconductor laser for mask assisted laser transmission micro joining PET and PET with clear weld absorbents, the mask slit width is 0.3mm, using CCD to plan experimental design. The mathematical model of joining process parameters with joint strength and joint width was established using response surface methodology. Experimental verification was also done. The actual joint width was compared to mask slit width and the process parameters were optimized. The results show that the mathematical model can response the relationship between process parameters and joining quality, the mask can effectively control the joint width, reasonable process parameters can obtain high-precision, high-intensity joining quality.
