The mounting plate is made of magnalium, the weight is lighter, influences of vibration are small, and the focusing effects can be ensured. In addition, a gear and rack transmission mode is adopted, the structure is simple, the maintenance is convenient, mounting is convenient, and the precision can meet demands of focusing. A stepper motor controls the gear to perform reciprocating motion on the rack, a holographic anti-counterfeiting label is imaged on the CCD camera, cost of the zooming mode is lower than that of an optical zooming mode, and the effects can reach the expected.
Description
Technical field
The present invention relates to a kind of automatic focusing mechanism for laser anti-counterfeit platform.
Background technology
Along with the raising of social progress and the false proof consciousness of people, holographic false proof is marked as picture as a kind of brand-new anti-counterfeiting technology, has obtained telling development.But existing anti-counterfeiting technology can't be satisfied the demand, be mainly reflected in that in cam movement process, to shake amplitude large, and cannot align in the process mid-focal length of vibrations, cannot focus on.Solution to this problem is at present generally to increase installation requirement.Increase installation requirement and also just increased the difficulty of installing, reduced efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, provide a kind of simple in structure, volume is little, quality is light, the process-cycle is short, precision is high and the automatic focusing mechanism for laser anti-counterfeit platform that meets design requirement.
For addressing the above problem, the technical solution adopted in the present invention is:
For an automatic focusing mechanism for laser anti-counterfeit platform, it is characterized in that: comprise telecontrol equipment and camera head; Described telecontrol equipment comprises propulsion system, the propulsion system camera head that is in transmission connection; Described camera head comprises video camera, and video camera is arranged on installing plate, and installing plate and propulsion system are in transmission connection.
Improve as one, described propulsion system comprise rack-mount 573P42 type stepper motor, and the corner of the every step of stepper motor is 1.2 °, and moment of inertia is 110gcm
2.
Improve as one, described stepper motor is connected with gear, and tooth bar is installed on installing plate, wheel and rack engagement.
Improve as one, the plate body that the magnalium plate that described installing plate is is 0.5-1cm by thickness is made, one end of plate body is fixed with tooth bar, and on plate body, video camera is installed.
Improve as one, described video camera is CCD camera video camera.
Improve as one, between described stepper motor and gear, be provided with shaft coupling.
Owing to having adopted technique scheme, compared with prior art, telecontrol equipment of the present invention comprises propulsion system, the propulsion system camera head that is in transmission connection.Camera head comprises video camera, and video camera is arranged on installing plate, and installing plate and propulsion system are in transmission connection.Installing plate of the present invention adopts magnalium material, and quality is lighter, affected by vibration little, has ensured focusing effect, meanwhile, adopts the rack-and-pinion kind of drive, simple in structure, easy to maintenance, easy for installation, and its precision meets focusing needs.In addition, the present invention is moved reciprocatingly on tooth bar by step motor control gear, thereby makes holographic false proof mark image in CCD camera, and zoom mode relatively optical zoom cost is low, and effect can reach expection.
Below in conjunction with the drawings and specific embodiments, the invention will be further described simultaneously.
