Description

technical field [0001] The invention relates to the technical field of optical fiber glue injection coating curing technology, in particular to a glue injection curing coating deformation isolation type optical fiber coating machine. Background technique [0002] The optical fiber coating machine re-coats the protective layer on the fused optical fiber, increases the strength of the fused part, and restores the original strength and elasticity of the fused part. It can be bent and wound normally, and will not be easily broken. The existing optical fiber coating machine separates the coating and positioning devices. Each time it is installed, it is necessary to perform three positionings on the clamps and coating parts on both sides, which consumes a lot of time. Long, when applying glue, put the optical fiber fusion splicing part directly into the coating groove, manually inject glue and fix it, due to the error of personal experience, the thickness of the coating part is un...

[0002] The optical fiber coating machine re-coats the protective layer on the fused optical fiber, increases the strength of the fused part, and restores the original strength and elasticity of the fused part. It can be bent and wound normally, and will not be easily broken. The existing optical fiber coating machine separates the coating and positioning devices. Each time it is installed, it is necessary to perform three positionings on the clamps and coating parts on both sides, which consumes a lot of time. Long, when applying glue, put the optical fiber fusion splicing part directly into the coating groove, manually inject glue and fix it, due to the error of personal experience, the thickness of the coating part is uneven, and the quality of the glue coating cannot be guaranteed. As a result, when the optical fiber is used later, the coating protective layer is easily damaged, which greatly increases the failure rate. In addition, the optical fiber cannot be directly clamped, otherwise it will cause clamping damage to the optical fiber, which will affect the subsequent use of the optical fiber. The glue coated on the optical fiber is due to its own Flow performance, if you do not observe at all times when injecting glue, and the operation is not timely, it will easily cause glue overflow. Due to the high viscosity of the glue, it is not easy to clean up, which will affect the continuous operation and reduce the curing efficiency of glue injection
