基于CCD传感器的玻壳最佳合模时刻判定

Determining the optimal sealing time of quartz glass tube based on CCD sensor system

玻管夹封工艺是影响高强度气体放电灯(HID)寿命和光效品质的重要因素之一,而对玻璃材料烧融状态的确定是其中关键的环节。通过对石英玻壳熔融状态下光热特性的分析,建立一套基于CCD传感器的视频图像采集系统,获得最佳的合模时刻,保证良好的封装气密性,提高自动化加工的整灯合格品率。

Determining the melting state of glass is a key step in extruded-beam sealing procedurewhich plays an important role in improving HID lamps life and luminous efficacy. By analyz-ing the light-heat peculiarity of melting quartz glass tube, a set of video image collectionsystem based on a CCD sensor is established. It can offer the optimal sealing time so thatthe tube be sealed well. In this way, the rate of the qualified Iamps may be increased inautomatic machining.
