To raise the utilization rate of laser edge bonding machine, reduce the process cost and improve the environmental safety of processing through improving the structure of the laser edge banding machine. Special laser edge banding was heated to achieve laser edge bonding process based on thermal radiation and the theory of rheology on polymer. The laser rays were integrated for the second time to enhance the utilization rate of laser and guarantee accurate laser path with the spectroscope as the second me-dium based on the refraction and reflection principle. The path of laser rays could be integrated as expected. The parts that didn’t be absorbed owing to the reflection of edge banding can be used again. It raises the ratio of laser utilization of laser edge banding machine, achieves more accurate temperature control of the laser edge, reduces the processing costs and improves the processing environment integrally.
