[0003] However, under the existing technical conditions, the path limiting mechanism of numerical control laser robot processing machine has some shortcomings, such as the following aspects:

[0004] 1. The buffering effect is not ideal: only a simple spring buffer is provided, and it is difficult to fully absorb energy in the face of high-speed emergency stop and overload impact of numerical control laser robot processing machine, causing hard collision and damaging important components such as slide and laser head connecting assembly;
