Problems solved by technology

[0003] In the process of studying the application, the inventor found that there are at least the following problems in the prior art: due to the lens error and mechanical assembly error in the cutting head, the zero focus position of the cutting head is different, in order to ensure different batches of production The cutting head can use the same cutting process parameters when cutting the same plate on the machine tool, so it is necessary to unify the relative height of the zero focus to the end face of the cutting nozzle

Abstract

The embodiment of the invention discloses an optical fiber cutting head zero focus measurement system and method, and relates to the technical field of laser processing. The optical fiber cutting headzero focus measurement system is applied to detecting of an optical fiber cutting head and comprises an optical fiber light-entering point stimulation jig, a cutting nozzle end surface stimulation jig and a lens integrated measuring instrument; the optical fiber light-entering point stimulation jig is mounted at a light-entering opening of the optical fiber cutting head, and the cutting nozzle end surface stimulation jig is mounted at a cutting nozzle of the optical fiber cutting head; and the optical fiber cutting head is arranged on the lens integrated measuring instrument, wherein the lensintegrated measuring instrument emits a first testing light ray and a second testing light ray for measuring of the zero focus absolute height and the cutting nozzle absolute height. According to theoptical fiber cutting head zero focus measurement system, the accuracy of zero focus measurement of the optical fiber cutting head is improved, meanwhile, operation is easy, and batched testing of the optical fiber cutting head can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of laser processing, in particular to a zero-focus measurement system and measurement method for an optical fiber cutting head. Background technique [0002] The optical fiber cutting head follower sensor can keep the distance from the cutting nozzle to the surface of the plate floating within the range of 0.8-1mm. At this time, the zero focus of the optical fiber cutting head needs to be unified at 1mm outside the cutting nozzle. [0003] In the process of studying the application, the inventor found that there are at least the following problems in the prior art: due to the lens error and mechanical assembly error in the cutting head, the zero focus position of the cutting head is different, in order to ensure different batches of production The cutting head can use the same cutting process parameters when cutting the same plate on the machine tool, so it is necessary to unify the...
