Description
Technical field
The utility model relates to data acquisition equipment field, particularly relates to a kind of polygonal mirror tumbler.
Background technology
Polygonal mirror tumbler is used for digital independent, is applied particularly to laser bar code identification equipment, phased-array laser radar, AGV(AutomatedGuidedVehicle) i.e. " automatical pilot transportation vehicle ", laser cubing equipment etc.Adopt laser to scan on picture, just can read the data on picture according to the power of reverberation in surface to be scanned, polygonal mirror tumbler is fast owing to being partial to speed, can make continuous print light deflection, can record or read highdensity data at a high speed.
Polygonal mirror tumbler main is at present all the rotating shaft directly utilized on electric motor, is directly fixed in rotating shaft by polygonal mirror module, drives the motion of polygonal mirror module with rotating shaft.Such technical scheme can produce larger space requirement, and general electric motor drive current is also larger, cannot be suitable for for needing miniaturized low-power consumption product.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of polygonal mirror tumbler, described polygonal mirror tumbler comprises coil windings and is placed in the polygonal mirror rotor module directly over coil windings, the annular magnet of the electromagnetic field effect produced by coil windings in polygonal mirror rotor module, the polygonal mirror on annular magnet is driven to rotate, avoid motor driving annular magnet to rotate, produce large and that power consumption the is large problem that takes up room.
To achieve these goals, the technical solution adopted in the utility model: a kind of polygonal mirror tumbler, comprise base plate, it is characterized in that, described base plate is provided with power drives parts, depressurize unit and coil windings, described power drives parts provide the working power needed for coil windings, described power drives parts are connected with depressurize unit, the operating voltage that described depressurize unit exports for reducing power drives parts, to increase the electric current flowing through coil windings, described polygonal mirror tumbler also comprises polygonal mirror rotor module, described polygonal mirror rotor module is positioned at directly over coil windings, described polygonal mirror rotor module comprises housing, be arranged on the bearing in housing, around annular magnet and the polygonal mirror be arranged on outside annular magnet of bearing.
Adopt such scheme, start power drives component working, depressurize unit reduces the operating voltage that power drives parts export, and increase the electric current flowing through coil windings, coil windings generates an electromagnetic field, act on annular magnet, drive toroidal magnet moves, and annular magnet arranged outside has polygonal mirror, and polygonal mirror rotates thereupon, the technical program realizes the effect of polygonal mirror rotation with less actuating force, and loss is little.In addition, adopt depressurize unit, reduce the operating voltage that power drives parts export, when power is constant, increase the electric current flowing through coil windings, can reduce the use of coil windings further, joint space-efficient greatly reduces use cost simultaneously.
Wherein, described base plate is pcb board.
Wherein, described depressurize unit is DCDC depressurize unit.
Wherein, described polygonal mirror rotor module and the distance range of coil windings are 0.18mm-0.3mm.
Wherein, described housing is working of plastics.
Wherein, described annular magnet is the annular magnet of four phase polarization.
Compared with prior art, the beneficial effect of the utility model realization: polygonal mirror tumbler of the present utility model takes up room little, and loss is low, greatly reduces use cost.
Accompanying drawing explanation
The utility model is further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the utility model polygonal mirror tumbler;
Fig. 2 is the structural representation of the polygonal mirror rotor module of the utility model polygonal mirror tumbler.
Embodiment
As Fig. 1, shown in 2, a kind of polygonal mirror tumbler, comprise base plate 1, described base plate 1 is provided with power drives parts, depressurize unit and coil windings 2, described power drives parts provide the working power needed for coil windings 2, described power drives parts are connected with depressurize unit, the operating voltage that described depressurize unit exports for reducing power drives parts, to increase the electric current flowing through coil windings 2, described polygonal mirror tumbler also comprises polygonal mirror rotor module 3, polygonal mirror rotor module 3 is positioned at directly over coil windings 2, described polygonal mirror rotor module 3 comprises housing 4, be arranged on the bearing 5 in housing 4, around annular magnet 6 and the polygonal mirror be arranged on outside annular magnet 6 of bearing 5.
Preferably, described depressurize unit is DCDC depressurize unit.
Described polygonal mirror tumbler also comprises MCU controller 7, MCU controller 7 and is connected with power drives parts, and MCU controller 7 controls the operating voltage size that power drives parts export.
MCU controller 7 controls power drives component working, the operating voltage that power drives parts export passes to DCDC depressurize unit, voltage signal after the process of DCDC depressurize unit passes to coil windings 2, coil windings 2 produces electromagnetic induction phenomenon, act on annular magnet 6, annular magnet 6 is with bearing 5 for rotating shaft rotates, and annular magnet 6 arranged outside has polygonal mirror, and polygonal mirror rotates thereupon.
Polygonal mirror tumbler of the present utility model take coil windings as stator, and the polygonal mirror rotor module at toroidal magnet place is rotor, and the electromagnetic induction rotor driven that stator produces rotates, and realizes the effect that polygonal mirror rotates thereupon; Polygonal mirror tumbler of the present utility model is avoided using machine shaft to drive polygonal mirror to rotate, and take up room little, energy consumption is low.
Above-mentioned embodiment is exemplary, is to enable those skilled in the art understand this patent better, can not be interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
