Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is further illustrated.
As shown in Fig. 1 ~ 5: from non-homogeneous, the circular laser facula A of pulse laser incidence, energy is super-Gaussian distribution, first it enter lenticule 1, lenticule 1 is the shape in footpath, rim of the mouth is square lens arra, the light of laser facula can be spatially divided into N equal portions by it, after through second lens---condenser lens 2, the focal plane of condenser lens 2 carries out energy redistribution, and scioptics 2 and lens below thereof are by these N equal portions overlapping (specifically can consult kohler's illumination) on focal plane.Because the sub-lens of microlens array is smaller, the energy of every part of light can be similar to thinks even, and the result of final superposition also can be even.
Lenticule 1 and condenser lens 2 form laser homogenizing shaping optical module.Lenticule 1 and condenser lens 2 are separately fixed in respective lens barrel 12, and adopt mechanical trim ring 10 to be mechanically fixed in housing.
Spot size regulating system, forms primarily of lens 3, lens 4, lens 5, and these 3 lens are separately fixed in respective lens barrel 12, and the lens barrel 12 of lens 5 is adopt mechanical trim ring 10 mechanically, is fixed on the tail end of cutter.The lens barrel 12 of lens 3, lens 4 is adopt mechanical trim ring 10 it to be fixed in respective picture frame 14, and the position of lens 3, lens 4 place picture frame can move forward and backward.The theory of mechanics of movement: cam revolves cylinder 8 inside two cam paths, cam path has positioning function, the edge of lens 3 and lens 4 place picture frame 14 respectively stretches out an important actor 15, and the cam path revolving cylinder 8 respectively with rotating cam is engaged mutually, thus, drive lens 3 and lens 4 move axially along optical axis when revolving cylinder 8 by rotating cam in housing, thus change lens 3 and lens 4 front and back position and interval, change lens 3 and lens 2, relative distance between lens 4 and lens 5 simultaneously, realize the change of the whole focal length of battery of lens, finally realize zoom function.
Hall element 7 is arranged on mechanical cover 6 surface, Hall element be utilize magnetic field electric current by time the Hall voltage that causes judge the power in magnetic field.The position that the mechanical cover inwall of laser cutting tool is different againsts different permanent magnetism sheets 11, the arrangement of multiple Hall elements 7 pairs of permanent magnetism sheets 11 is adopted to respond to, during rotary cutter, the permanent magnetism sheet arrangement that different laser power densities is corresponding different and magnetic field, by the induction of Hall element 7, concrete Output of laser hot spot power and spot size information can be obtained, these information all with the numerical monitor of correspondence on the viewable numbers graduated disc 9 being arranged on tool surface.
Cam revolves the direction of rotation of cylinder 8 and amplitude regulates according to scale shown on the viewable numbers graduated disc 9 be arranged on cutter outer surface, cylinder 8 is revolved by rotating cam, drive lens 3 and lens 4 change lens front and back position and interval according to designing requirement, different lens position and interval will change power and the size of Output of laser hot spot, these information by Hall element 6 Real-time Feedback on the viewable numbers graduated disc 9 being installed on cutter outside.
When cam being revolved cylinder 8 and rotating in a counter-clockwise direction on earth, as shown in Figure 3, B is minimum for square, the homogenize laser facula that at this moment export in the position of lens 3, lens 4; When now adjustment cam revolves cylinder 8 clockwise again, lens 3, lens 4 do corresponding movement respectively in systems in which, and output facula B increases gradually, and when lens 3, lens 4 move to position shown in Fig. 4, output facula B size increases to original twice; Continue clockwise adjustment knob 8, the area of output facula B continues to increase continuously gradually, and when clockwise adjusting knob 8 is to top, now lens 3, lens 4 position are as shown in Figure 5, and system output obtains the laser facula B of maximum focal length, square, homogenize.
