Description

TECHNICAL FIELD

[0001] The application relates to the technical field of laser cutting processing, in particular to a three-dimensional optical fiber cutting machine. BACKGROUND

[0002] The optical fiber cutting machine is a laser cutting device using an optical fiber exciter as a light source in a laser cutting system, and is connected with a laser cutting head through a light fiber pulled from a laser emitter, so that high-energy laser beams generated thereby are used to realize high-precision cutting of materials, and is commonly used for manufacturing metal lampshades and the like. The optical fiber is mainly used for transmitting laser beams, and its structure allows light to be efficiently transmitted in an internal total reflection manner, thereby ensuring stable transmission of laser energy.

[0003] At present, the laser cutting head of the optical fiber cutting machine needs to be continuously lifted and swung during cutting to meet the cutting requirements of different angles. Since the optical fiber is pulled during continuous rotation of the laser cutting head, in order to avoid the fragile optical fiber from being pulled off when being pulled, a relatively long optical fiber length is increased in actual use to meet the rotation requirements of the laser cutting head. However, when the laser cutting head is rotated from the vertical position to the two sides,

[0004] The optical fiber is continuously pulled, and when the laser cutting head is rotated from the two sides to the vertical position, since the optical fiber near the laser cutting head is relatively long at this time, and the optical fiber cannot be effectively stretched, the optical fiber is excessively bent, for example, U-shaped bending, and the optical fiber is broken due to fatigue after a certain number of bending, thereby affecting the service life.
