Description
Technical field
The mounting head of the present invention a kind of micron order running accuracy refers to a kind of for electronic devices and components are placed with mounting head on circuit boards.
Background technology
In electronics industry, mounting head is the critical component that chip mounter realizes attachment function, and the attachment axle on mounting head not only rotates, and does axial linear movement；On mounting head, suction nozzle above-below direction moves and selects minitype cylinder to complete.Its function is made by level coordinates motor system, and from the feeding position pickup device of feed appliance element is accurately placed with on the setting position of circuit board by suction nozzle.Meanwhile, during element is transported to mounting position, utilize vacuum principle entrained elements securely.But the mounting head that circuit board package uses at present is owing to simply using motor, there is the shortcoming that moment of torsion is not enough；If simply using motor to coordinate decelerator, precision does not reaches again micron-sized requirement, it is therefore necessary to design a kind of novel mounting head to meet the market demand of reality.
Summary of the invention
The present invention seeks to for above-mentioned weak point, it is provided that the mounting head of a kind of micron order running accuracy, by motor and harmonic speed reducer, reached high torque and high-precision requirement.
The mounting head of a kind of micron order running accuracy takes techniques below scheme to realize: the mounting head of a kind of micron order running accuracy includes servomotor, harmonic speed reducer, mounting head framework, pressure pad, vacuum outlet, vacuum inlet, angular contact bearing, sealing shroud, flexible clutch and rotating shaft；
Mounting head framework is provided with harmonic speed reducer, on harmonic speed reducer top, servomotor is installed；Internally installed at mounting head framework has flexible clutch, flexible clutch one end is connected with harmonic speed reducer, the other end connects rotating shaft, rotating shaft is inserted in mounting head framework by mounting head lower frame, and be connected with flexible clutch, the marginal position inserting mounting head framework in rotating shaft is provided with angular contact bearing；Being close at angular contact bearing, be provided with sealing shroud in mounting head framework, the opening in sealing shroud is vacuum inlet；
Described rotating shaft is the hollow structure that one end is closed, it has been pasted with the pressure pad of cushioning effect away from the outer rim of one end of mounting head framework in rotating shaft, offering opening at the middle part of rotating shaft, offer passage in the mounting head framework corresponding with opening, the other end of passage is provided with vacuum outlet.
Described harmonic speed reducer includes harmonic oscillator, flexible cam and rigid wheel, harmonic oscillator is arranged in flexible cam, being provided with rigid wheel outside flexible cam, the outer surface at flexible cam is provided with gear, and the inner surface correspondence flexibility cam at rigid wheel is also equipped with gear.
Described angular contact bearing quantity is no less than two.
Described sealing shroud quantity is no less than two.
Harmonic Gears is to utilize the rotation of oval cam to make flexible cam engage with rigid wheel, disengage, thus the principle producing tooth difference displacement is made.When harmonic oscillator is active, harmonic oscillator rotates in flexible cam, flexible cam and thin-wall bearing is made to deform (controlled elastic deformation) nearby, at this moment the gear of flexible cam just enters the between cog of (engagement) or disengagement (nibble from) rigid wheel during deformation, it is at a fully engaged at the two ends of harmonic oscillator, and the tooth in remaining direction is just in and disengages completely.The now continuous rotation of harmonic oscillator, the engaging-in engagement just making between flexible cam and rigid wheel is nibbled out disengagement these four cycle of states and is back and forth constantly changing the most original engagement.This phenomenon is referred to as side set motion, the just motion of this side set, and the high-speed rotation of input just can become slowly running of output as decelerator.
In the engagement process of gear, the tooth of about 30%-50% is typically had to participate in engagement.The modulus of harmonic gear is the least, the number of teeth is a lot, error between tooth and tooth is the least, there is the region of engagement of symmetry plus Harmonic Gears, when a lot of teeth are simultaneously engaged, error between them can be cancelled out each other automatically so that produced by Harmonic Gears, angular errors is the least, thus substantially increases transmission accuracy.
In the mounting head of the present invention a kind of micron order running accuracy, gear ratio=50 of harmonic speed reducer, use servomotor, much less than motor of servomotor angular errors, then through harmonic speed reducer, angular errors is the most reduced 50 times.Thus can reach the purpose precisely indexed.
Mounting head uses motor and harmonic speed reducer composition to have two effects: can increase moment of torsion after one, slowing down, meet low-speed motion characteristic, only according to stepping, moment of torsion is not enough.Two, after slowing down, often the make a move precision of elongation of stepping is exaggerated, and can reach micron order.
