Description
Technical field
The present invention relates to voice coil motor field, particularly to a kind of integrated form voice coil motor module.
Background technology
Voice coil motor is because its simple in construction is small and exquisite, reliability is high, energy conversion efficiency is high, response is quick, action is smooth, logical
It is commonly used in high acceleration, high-precision occasion, and along with the continuous maturation of motor-drive technique, application occasion is more and more extensive.
These characteristics make voice coil motor be particularly suitable for applications in multidimensional drive terminal of manipulator, its small and exquisite structure and less weight,
Making the manipulator can be with the running of higher speed, and the vibrations brought be less.As above many occasions in order to improve further speed and
Production capacity, the requirement to voice coil motor is more and more higher, to such an extent as to the most traditional voice coil motor structure is unable to reach use requirement.
The application of voice coil motor is generally as shown in publication number CN204271804U at present, and voice coil motor is divided into stator and mover, dynamic
Generally it is packaged with coil on son, stator is provided with magnet.Stator is installed on the base fixed again, base is arranged linear sliding
Rail, the motion parts installation plummer of linear slide rail, plummer is connected with the mover of voice coil motor again, constitutes voice coil motor mould
Group.The commonly provided above-mentioned voice coil motor module of voice coil motor supplier, or more commonly sell the mover of voice coil motor and determine
Son, then be similar to the mechanism of above-mentioned modular structure by engineer's designed, designed of user and use.
Above-mentioned traditional structures and methods make voice coil motor there is the moving loads that part is unnecessary, and fixed component there is also one
Divide unnecessary weight and volume.The most not only have impact on the high speed response property of voice coil motor, and to driving whole voice coil loudspeaker voice coil electricity
Speed and response characteristic is also reduced for the bottom layer driving system of machine module motion.Its bigger volume and the response of slower system
Feature limits voice coil motor many application industrially.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, design a kind of extremely compact integrated form voice coil motor module, decrease voice coil loudspeaker voice coil electricity
Machine moving component and the weight and volume of fixed component, increase the advantage of voice coil motor to greatest extent, is allowed to can be applicable to more pole
The occasion of end or demand, it also avoid the systematic function decline that the most professional many application design causes simultaneously.
The technological means of the present invention is: the stator design of base with voice coil motor is integrated, i.e. magnet is set directly at integral type
In stator base；Guide rail is also set directly in integral type stator base；Integral type stator base is additionally provided with fixes for entirety
Base installing hole；The encoder head that integral type stator base is also equipped with grating scale corresponding fixes seat.Same thinking,
The mover of voice coil motor and motion plummer are also configured as one, i.e. coil and are directly embedded into or fix setting being contained in integrally by coil
On formula mover support plate, integral type mover support plate is provided directly with guide rails assembling screwed hole, integral type mover support plate the most directly sets
It is equipped with the load installing hole for installation load, integral type mover support plate is also provided directly with grating scale.Integral type mover support plate
Magnetic force line conduction effect with the structure of integral type stator base i.e. efficiently accomplishes voice coil loudspeaker voice coil stator, also ensure that coil connects as much as possible
The position of the load screwed hole of nearly mover plummer, greatly reduces load weight and the overall weight of voice coil motor, the most greatly
Reducing overall volume, reduce leakage field and improve system rigidity, the volume and weight of the present invention only has traditional voice coil motor module
About 50%.Above so that the quick positioning performance of voice coil motor is increased dramatically.
