Description
Technical field
The present invention is about a kind of balancing optical assembly, especially about a kind of detachable balancing optical assembly.
Background technology
Image projecting system is one of the most popular subitem in present opto-electronics, and the digital light in the popular now optical projection system is handled (Digital Light Processing, DLP) formula projector, system adopts digital control, and utilize the reflected light principle with after the light-source collecting, pass the colored filter of red bluish-green three-colour filter again via lens focus, be projected to digital micro-mirror device (DigitalMicro-mirror Device, DMD) on, owing to have many small movable lens on the digital micro-mirror device, see through drive electrode control movable lens angle of inclination and deflection period, the reflection direction by switches light throws imaging by camera lens again.
As shown in Figure 1, having now in digital light processing (DLP) formula projector is to be provided with in order to colorific optical module 1, comprises a motor 11, a colour wheel 12 and a cover plate 13.Wherein, cover plate 13 is arranged on the motor 11 with colour wheel 12, and motor 11 mainly is made up of a motor body 111 and 112 on axle center lid.In addition, optical module 1 more can comprise a positioning piece 14 and a winding displacement 15.This keeper 14 utilizes winding displacement 15 to be connected with a driver (not being shown among the figure), and this driver system is in order to CD-ROM drive motor body 111, and be the center rotation with a bit (rotating shaft core) that keeper 14 and 111 of motor bodies are established.
In optical module 1, the most expensive part is a motor 11.Yet,
In the prior art,, but the motor 11 that not have to damage can't be removed and reuse, or can only tool using firmly stick up out motor body 111 and 112 slit is covered in the axle center if when the colour wheel 12 in the optical module 1 is damaged.The not only dangerous but also instrument that use of this practice also may destroy motor 11, and makes motor 11 to reuse.
In addition, in order to promote the effect of beam split, colour wheel 12 in the rotating speed of motor 11 up to more than 7200 rev/mins, following its rotating speed even up to more than 144000 rev/mins.Therefore, when the center of rotation of colour wheel 12 departs from rotating shaft core, also promptly when center of rotation is not on rotating shaft core, cause the vibrations and the noise of colour wheel easily, also can influence fiduciary level and life-span influence in the running.
As shown in Figure 2, one of method of adjusting in the rotary balance of optical module 1 for prior art, system sees through periphery 131 Drillings one groove 132 at cover plate 13, in groove 132, place a counterweight 133, counterweight 133 is chimeric or is bonding in the groove 22 of cover plate 13, to proofread and correct the location of colour wheel 12 centers of rotation.
Yet optical module 1 is running up down for a long time, and counterweight 133 easily has the phenomenon of the groove 132 that becomes flexible even break away from cover plate 13 and produces the unbalanced shortcoming of optical module 1 unitary rotation.
Because the problems referred to above, the present invention proposes a kind of detachable balancing optical assembly that can solve above-mentioned cost and rotary balance problem.
Summary of the invention
Because above-mentioned problem, the detachable balancing optical assembly of purpose of the present invention for providing a kind of cover plate to have application of force district, with as the dismounting balancing optical assembly time, the usefulness of rotation cover plate and colour wheel.
Therefore, for reaching above-mentioned purpose,, comprise a motor, a colour wheel and a cover plate according to a kind of detachable balancing optical assembly of the present invention.Wherein, motor is arranged at a side of colour wheel, and cover plate is provided with the opposite side of colour wheel, and colour wheel is arranged between motor and the cover plate, and cover plate has at least one application of force district, is to be arranged at the surface of cover plate with respect to colour wheel.
From the above, because of complying with a kind of detachable balancing optical assembly of the present invention.Compared with prior art, cording has application of force district on the cover plate of the present invention, and the user can force in application of force district with instrument, to separate motor and colour wheel.Thus, not only can improve the good rate of motor after the dismounting, more can reuse motor to save cost.In addition, in embodiments of the invention, cording has at least one groove on the periphery of cover plate, the opening of groove has a stopper, so that groove is when inserting a counterweight, counterweight is difficult for flying out, and then can solve the optical module vibration problems and reduce the noise generation, and increases the fiduciary level of optical module running.
