Abstract
The invention relates to a light beam cutting drive mechanism and a light beam cutting system comprising the same. The light beam utilizes the lever principle, accordingly, the rotary torsion force of a drive motor is transferred onto a cutting piece by a lever supporting point through the drive mechanism, and the arbitrary-shape light spot effect is formed by the light beam cutting action of the cutting piece. The cutting piece jamming and light beam cutting speed limiting problems in the light beam cutting process are solved.

Background technology
In the stage illumination, lighting technical field, often need to use a kind of beam-shaping assembly at present, for tackling light beam to obtain the light beam of definite shape.
Cutting assembly now preferably the beam-shaping assembly be the light beam diced system, by cutting the combination of mating plate, carry out the cutting of arbitrary shape light beam, thereby form the hot spot of arbitrary shape, thereby expanded diversity and the flexibility of light spot shape, made the application orientation of stage lamp more extensive.
The technical essential of light beam diced system is the transmission mechanism of cutting blade, and the design of transmission mechanism is determining the motion mode of cutting blade, and the motion mode of cutting blade is determining the imaging effect of hot spot.In existing technology, be generally following three kinds of modes: 1) adopting is connecting rod-crank-type mechanism, by drive motors, drives crank, and then crank drives the connecting rod be connected with crank, and last connecting rod pulls cutting blade to move to cut light beam again; 2) driven wheel structure, driven wheel directly is fixed on drive motors, the teeth groove of cutting blade itself with the direct interlock of driven wheel, move to cut light beam thereby driven wheel directly drives cutting blade; 3) cam-push rod-guide board structure, cam is connected with drive motors, and push rod one end is connected with cutting blade, and the other end is connected with cam, and the cam driven push rod then drives cutting blade and moves to carry out the hot spot cutting.
For above-mentioned three kinds of transmission mechanisms, because of the torsion of drive motors be substantially 1:1 directly in cutting blade, if drive motors torsion is not enough, be easy to occur the situation of jam, therefore the torsion for drive motors requires very high; In addition, be activated the basic direct-drive of motor in cutting blade, the rotating speed of drive motors has directly determined the speed of service of cutting blade, and therefore the cutting speed of hot spot also is greatly limited.
Summary of the invention

The specific embodiment
The present invention relates to the light beam diced system that a kind of light beam cuts transmission mechanism and comprises this mechanism; According to an illustrative diagram embodiment of the present invention, as shown in accompanying drawing 1 and 3, the light beam diced system comprises body frame, a plurality of cutting blade, organizes executing agency more; Described executing agency comprises drive motors and transmission mechanism; Transmission mechanism mainly comprises the Tooth Profile sheet, drive flange, kinematic link, transmission pillar.
As shown in accompanying drawing 2 and 4, drive flange (5), Tooth Profile sheet (2), drive flange (3), kinematic link (4), cutting blade (7) to be connected successively; Drive flange (5) and Tooth Profile sheet (2) engagement, Tooth Profile sheet (2) is fixedly connected with drive flange (3), drive flange (3) is fixedly connected with kinematic link (4), and kinematic link (4) freely is connected by one section loose slot with cutting blade (7).
As shown in Figure 5, during drive motors (6) work, motor shaft rotarily drives driving flange (5) rotation be fixed on motor shaft, drive flange (5) to rotarily drive Tooth Profile sheet (2) and rotate, and the rotation of Tooth Profile sheet (2) further drives drive flange (3) and be fixed on kinematic link (4) motion on drive flange (3); Kinematic link (4) freely is connected in one section loose slot with cutting blade (7), and kinematic link (4) motion drives cutting blade (7) and planar moves.
As shown in Figure 3, light velocity diced system is comprised of many groups transmission mechanism (1), when many groups transmission mechanism (1) routing motion, organizes cutting blade (7) more and moves in plane separately respectively, cuts beam motion; By certain programmed instruction, organize cutting blade (7) more and carry out predetermined light beam cutting under the effect of the cutting of light beam separately transmission mechanism, thereby form the hot spot effect of arbitrary shape.
