Abstract
The invention discloses an active optical fiber winding device and an optical fiber winding method for an optical fiber laser. The winding device is a radiating disc with a conical shape; continuously arranged winding slots are formed in the conical surface of the radiating disc; each winding slot is provided with two symmetrical slot walls; the section included angle alpha of every two slot walls is 90 degrees; an interval is remained between the adjacent optical fibers in the winding slots. Stress caused by the direct contact between the optical fibers is avoided, a better radiating effect is achieved and the burning loss phenomenon is avoided.
Description
Technical field
The present invention relates to a kind of coiling apparatus for fiber laser Active Optical Fiber and coiled fiber method.
Background technology
At present, fiber laser, as the representative of third generation laser technology, has the unrivaled superiority of solid and gas laser, comprises that volume is little, good beam quality, electric light transformation efficiency is high, operating cost is low, machining accuracy is high; Fiber laser has been widely used in material processed and the high-end manufacturing industry of machining, and market prospects are boundless.In large-power optical fiber laser fibre core, power density is very high, the heat producing is also very high, in use must to Active Optical Fiber carry out heat dissipation plate around, if fiber reel is around improper, very easily produce stress, in long-term use procedure, inside of optical fibre is easily impaired, cause energy concentration of local, thereby cause optical fiber scaling loss, the coiling method of the Active Optical Fiber of the fiber laser on market has two kinds now: a kind of is the method for coiled fiber on aluminium matter cylinder, optical fiber becomes shape of threads to be coiled on smooth cylinder, in order not allow optical fiber landing from cylinder, optical fiber and optical fiber not only need direct close contact, also to allow optical fiber have certain pretightning force, act on optical fiber is that pulling force has also produced stress at inside of optical fibre, also has a kind of flat fiber reel around mode, optical fiber becomes vortex-like drum on an aluminium matter heat radiation flat board, do not need the pretightning force of optical fiber, cylinder coiling relatively, the advantage of this mode is effectively to have eliminated fiber reel to walk around the stress in journey, but due to be the pendulum of free fall type on heat-dissipating aluminium plate, have some optical fiber not drop on completely on heating panel, cause optical fiber heat radiation inhomogeneous, fiber reel around diameter also have randomness.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, a kind of coiling apparatus for fiber laser Active Optical Fiber is provided, it not only can avoid optical fiber directly to contact generation stress with optical fiber, and can dispel the heat better, avoids the phenomenon of scaling loss.
The present invention solves the problems of the technologies described above the technical scheme of taking: a kind of coiling apparatus for fiber laser Active Optical Fiber, comprise and be cone shape heat dissipation plate, on the conical surface of heat dissipation plate, have and be the groove that spirals that continuous shape is arranged, the groove that spirals has two symmetrical cell walls, and the cross section angle α of two cell walls is 90 °, between the adjacent optical fiber spiraling in groove, leaves interval.
Further, described heat dissipation plate is made by aluminium.
The present invention also provides a kind of coiled fiber method of the coiling apparatus for fiber laser Active Optical Fiber, the step of the method is as follows: optical fiber ecto-entad is coiled in and is spiraled in groove, and two some contact sites on optical fiber are connected with two cell walls of the corresponding groove that spirals.
Adopted after technique scheme, because optical fiber can be coiled in, spiraled in groove, and leave interval between the adjacent optical fiber spiraling in groove, this has just been avoided direct contact the between optical fiber and optical fiber, has avoided concentrating of heat, has avoided the phenomenon of scaling loss; Fiber reel is around 90 ° spiral in groove, and two cell walls become V-structure, and under freely falling body is placed, optical fiber has two points to drop on cell wall, has increased the contact area of optical fiber and heat dissipation plate, can effectively dispel the heat; In addition, the fiber reel that the present invention has guaranteed each laser around shape be certain with size, because optical fiber is coiled in, spiral in groove, limited fiber reel around radius, avoided flat fiber reel around randomness.Low the inside, heat dissipation plate of the present invention edge is high, has facilitated the end end of optical fiber to draw.
Accompanying drawing explanation
Fig. 1 is the structural representation of the coiling apparatus for fiber laser Active Optical Fiber of the present invention;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Fig. 3 is the schematic diagram of coiled fiber method of the present invention.
Embodiment
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation below.
As shown in Fig. 1 ~ 3, a kind of coiling apparatus for fiber laser Active Optical Fiber, comprise and be cone shape heat dissipation plate 1, on the conical surface of heat dissipation plate 1, have and be the groove 1-1 that spirals that continuous shape is arranged, the groove 1-1 that spirals has two symmetrical cell wall 1-1-1, and the cross section angle α of two cell wall 1-1-1 is 90 °, between the adjacent optical fiber spiraling in groove 1-1, leaves interval.
As shown in Figure 3, a kind of coiled fiber method of the coiling apparatus for fiber laser Active Optical Fiber, the step of the method is as follows: optical fiber ecto-entad is coiled in and is spiraled in groove 1-1, and two some contact sites on optical fiber are connected with two cell wall 1-1-1 of the corresponding groove 1-1 that spirals.
Operation principle of the present invention is as follows:
Because optical fiber can be coiled in, spiral in groove 1-1, and leave interval between the adjacent optical fiber spiraling in groove 1-1, this has just been avoided direct contact the between optical fiber and optical fiber, has avoided concentrating of heat, has avoided the phenomenon of scaling loss; Fiber reel is around 90 ° spiral in groove 1-1, and two cell wall 1-1-1 become V-structures, and under freely falling body is placed, it is upper that optical fiber has two points to drop on cell wall 1-1-1, increased the contact area of optical fiber and heat dissipation plate 1, can effectively dispel the heat; In addition, the fiber reel 1 that the present invention has guaranteed each laser around shape be certain with size, because optical fiber is coiled in, spiral in groove 1-1, limited fiber reel around radius, avoided flat fiber reel around randomness.Heat dissipation plate of the present invention 1 low the inside, edge is high, has facilitated the end end of optical fiber to draw.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the present invention is solved further describe; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
