Laser optical path system and laser resistance trimming machine

The utility model provides a laser light path system and a laser resistance trimming machine. The laser light path system is used for achieving laser cutting of the workpiece to be machined. The laser light path system comprises a light path platform, and a laser, a light beam limiting module, a marking execution module, a transflective module and a position detection module which are arranged on the light path platform. The laser light path system forms a laser transmission light path and a visible light detection light path. In the laser transmission light path, an incident laser beam passes through the transflective module, the beam limiting module and the marking execution module and reaches a workpiece to be machined. In the visible light detection light path, incident visible light passes through the marking execution module, the light beam limiting module and the transflective module to reach the position detection module. In the laser light path system, different laser processing and detection paths a
