By adopting the structure, the voice coil motor can achieve the object that the motor directly drives the load to reciprocate and realize the high-speed precise positioning of the load.
Description
[technical field]
The present invention relates to a kind of motor, relate in particular to a kind of linear voice coil motor.
[technical background]
Along with development of modern industry, voice coil motor has obtained application more and more widely in line with its distinctive high response, high acceleration, high-speed, characteristics that volume is little.Yet rectilinear motion is traditionally normally realized by synchronous band, screw rod or ball-screw conversion indirectly by electric rotating machine, and the machine driving response is slow and hysteresis, there is certain tracking error, also influence the transmission stiffness of system, mechanically operated wearing and tearing and noise or the like all are the technical bottleneck of indirect drive in the high speed and precision automation equipment.The direct driving technologies that is made of linear electric motors has been cancelled the intermediate link between motor and the load, driving-chain between motor and the workbench is shortened to zero, having avoided shortcomings such as the backlass in the lead screw transmission, inertia, frictional force and rigidity deficiency, is the technological trend in markets, field such as high-end automation equipment, Digit Control Machine Tool.
Therefore, the problem that how to provide a kind of linear voice coil motor to become current urgent need to solve.
[summary of the invention]
The technical problem that institute of the present invention desire solves provides a kind of linear voice coil motor, and is poor by the caused rigidity of traditional ball-screw transmission to overcome, efficient is low, low-response and have shortcoming such as backlass.
The technical solution adopted in the present invention is: a kind of linear voice coil motor, the mover that comprises stator, relative stator motion, wherein, described stator comprises base plate, coil and coil stationary plate, offer the coil mounting groove on the described coil stationary plate, described coil is contained in the described coil mounting groove, and described base plate, coil and coil stationary plate adopt the epoxide resin vacuum perfusion to be installed together; Described mover comprises yoke and magnet, and described magnet pasting is on described yoke.
Offer the cooling holes of passing through for cooling fluid on the described base plate.
But be provided with the temperature inductor that the perception coil temperature changes between the described coil.
The technique effect that the present invention reached is: linear voice coil motor of the present invention can realize that by adopting said structure mover directly drives load and does reciprocating linear motion, and realizes the high speed and precision location of load.
[description of drawings]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.

See also Fig. 2, Fig. 3 simultaneously, stator 10 comprises base plate 11, coil 12 and coil stationary plate 13, and coil 12 is installed between base plate 11 and the coil stationary plate 13.Offer the cooling holes 111 and the some screw holes 112 that pass through for cooling fluid on the base plate 11.Coil stationary plate 13 offers coil mounting groove 131 on 11 of base plates, coil 12 is contained in this coil mounting groove 131.Coil stationary plate 13 offers line ball hole 132 in a corner location.Coil 12 comprises one at least, in actual use, can reach the number of the actual size design coil 12 of base plate 11 and coil stationary plate 13 according to actual needs, and preferred embodiment coil 12 of the present invention is two.Be provided with temperature inductor 14 between two coils 12, when stator 10 internal temperatures are too high, so that produce overtemperature protection.Described base plate 11, coil 12 and the perfusion of coil stationary plate 13 usefulness epoxide resin vacuums form.When linear voice coil motor 1 is assembled with external device (ED), by described screw hole 112 stator 10 and external device (ED) are fixed with some screws.External power cord couples together by described line ball hole 132 and coil 12, by Printed Circuit Board (PCB) pad 15 and line ball piece 16 it is sealed, and fixes with screw 17.
See also Fig. 4, mover 20 comprises yoke 21 and magnet 22.Yoke 21 also generally is cuboid.This yoke 21 is made by high permeability material.Whenever at intervals be provided with raised line 211 on the described yoke 21, these raised lines 211 are separated into some minizones with yoke 21.In the corresponding respectively minizone that sticks on the yoke 21 of each magnet 22.The quantity of magnet 22 is at least one, and in actual use, the actual size that can reach yoke 21 according to actual needs decides the number of magnet 22, and preferred embodiment magnet 22 of the present invention is three.Described three magnet form huge array in the corresponding respectively minizone that sticks on the yoke 21.
In sum, linear voice coil motor 1 of the present invention can realize that by adopting said structure mover directly drives load and does reciprocating linear motion, and realizes the high speed and precision location of load.
