Description
Technical field
The utility model relates to a kind of rotating mechanism, more particularly, relates to high frequency rotating mechanism and wire bonder in the wire bonder.
Background technology
The lead-in wire bonding is as the important technology of semiconductor die package, and its packing forms accounts for more than 90% of IC encapsulation.In lead key closing process, conductive lead wire need and be sent to bonding station by the anchor clamps clamping, is stripped from position then, is bonded at last on the electrode and chip on the semiconductor chip.Lead-in wire usually adopts a rotating mechanism to accomplish above-mentioned action after by the anchor clamps clamping.In recent years, along with the very big raising of the wire bonder speed of service, therefore higher requirement had been proposed also the rotating mechanism that can drive the anchor clamps rotation.Because wire clamp is positioned near the transhipment axle, in order to realize the rotation of high acceleration, deceleration, requires the inertia of rotating mechanism as far as possible little; Simultaneously, the rotating mechanism on the wire clamp also need have high static state and dynamic rate, guarantees to have higher resonance frequency with this; After could guaranteeing each action like this, remaining vibration all is a short arc, high-frequency; And but fast and stable gets off, and the para-linkage quality produces injurious effects.And existing rotating mechanism does not also reach above-mentioned requirement, therefore demands urgently improving.
The utility model content
The utility model technical problem to be solved is to overcome the defective of prior art, and the height that a kind of simple in structure, high stability and high reliability be provided is rotating mechanism and adopt the wire bonder of this rotating mechanism frequently.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of high frequency rotating mechanism is provided, comprises clamp body and be located on the said clamp body and two rotating parts of coaxial line; Said clamp body comprises first anchor clamps and second anchor clamps that are oppositely arranged, and each rotating part includes the first ceramic support cup that is fixed on said first anchor clamps, be located on said second anchor clamps and drive down the rotating second ceramic support cup and be located between said first, second ceramic support cup and can be with the ceramic bead of second ceramic support cup rotation at a dynamical element.
Particularly, the said first ceramic support cup and the second ceramic support cup all have arc groove, and cavity inner surface and said ceramic bead outer surface that two arc grooves surround formation are complementary.
Further, be provided with the preload piece that can make the said first ceramic support cup, the said second ceramic support cup compress applying respectively with said ceramic bead between said first anchor clamps and said second anchor clamps.
Preferably, said preload piece is a compression spring.
The utility model also provides a kind of wire bonder, and it comprises above-mentioned high frequency rotating mechanism.
In the utility model, each rotating part forms a rotational restraint point, between these two rotational restraint points, forms a virtual rotation axis, and the rotating part of such two coaxial lines promptly forms one can be around the rotating mechanism of this virtual rotation axis rotation; Rotating mechanism adopts ceramic material, and by the smoothness of ceramic material surfaces, the high smooth degree between the rotor contact-making surface of raising rotating mechanism reduces rotary resistance, realizes high speed rotating on the one hand; On the other hand because ceramic material has excellent surface hardness; Can bear more than one hundred million times motion repeatedly, therefore have very high repeating motion precision, and have higher resonance frequency; But fast and stable gets off after guaranteeing each action, and the para-linkage quality does not produce injurious effects; Simultaneously, ceramic material has insulating properties and higher thermal stability, can guarantee in the temperature range of broad, and this rotating mechanism still has the reliability and the motion consistency of height.
