Description

A kind of crystal bar clamping tooling

Technical field

The utility model relates to a kind of sapphire processing assemblies, and in particular to a kind of crystal bar clamping tooling belongs to sapphire Processing assembly technical field.

Background technique

Sapphire crystal is anisotropic crystalline material, and has excellent electricity, light, heat, mechanical characteristic.In recent years Come, with the extension that crystal is applied in photoelectron, information industry, very high request proposed to chip machining accuracy, and conduct The crystalline material of epitaxial growth substrate is even more to propose strict demand to crystal face angle orientation machining accuracy.Thereby, it is ensured that crystal from It is to produce the important link of high-quality metering device and substrate that blank, which is processed into crystal face angle orientation precision in finished product,；Sapphire ingot Processing technology are as follows: crystal ingot draws stick → crystal bar and cuts both ends → crystal bar end surface grinding → mill OF datum level → slice；Sapphire ingot exists The processing that the positioning surface (reference planes) of crystal bar is carried out after crystallization direction must be measured before slice processing to crystal bar；In this way, On the one hand it may insure its correct position on slicer, it is on the other hand, specific in identification sapphire ingot or chip Crystallization direction is conducive to identification of the chip in subsequent handling, positioning requirements；To crystal bar positioning surface processing common method be Flitch is placed on direction finder, crystal bar is measured after crystallization direction just on direction finder by crystal bar bonding to flitch, then will Entirety is placed in the processing that crystal bar positioning surface is carried out on grinder.This method due to being manually bonded crystal bar there are operating error, from And certain deviation can be brought to the positioning of crystal bar crystallization direction, it will affect the processing of subsequent wafer；In addition, will also be to viscous after processing The crystal bar connect carries out processing of removing photoresist, and it is laborious not only to have taken function, but also production efficiency is low；For this purpose, Chinese Patent Application No.: 201511027942.X discloses a kind of orientation fixture that automation is processed for the face sapphire ingot OF, including detachably connects The upper fixture connect and lower fixture, V-groove is offered on lower fixture upper surface, and upper fixture is used to sapphire ingot being fixed on V-type In slot, V-groove includes being distributed in two sides and symmetrical left tilted surface and right tilted surface, offers phase on left tilted surface and right tilted surface Mutual symmetrical pulley groove is equipped with shaft in pulley groove, idler wheel is set in shaft, shaft is equal with the length direction of lower fixture Row, idler wheel and left tilted surface/right tilted surface are tangent or slightly externally protrude out in left tilted surface/right tilted surface.Shaft on left tilted surface and right tilted surface connects It is connected to synchronous motor；Sapphire ingot positioning fixture is divided into two parts up and down by the present invention, by left tilted surface and right tilted surface Increase idler wheel, crystal bar can be rotated automatically, adjust crystal bar position, convenient for the position adjustment before sapphire ingot processing, positioning accurate Standard saves manpower；But its outer diameter for clamping crystal bar is restricted；In addition, it carries out positioning clamping by idler wheel, automatic rotation is realized Turn crystal bar, but when completion positioning needs to process, due to moving vibration etc., is easy because idler wheel causes positional shift.

Utility model content

A kind of in order to solve the above problems, the utility model proposes crystal bar clamping tooling, can receive the crystal bar of big outer diameter Processing, and can auxiliary positioning, can be realized close clamping after positioning, guarantee is transferred to grinding plate process will not positioning.

The crystal bar clamping tooling of the utility model, including the upper fixture being detachably connected and lower fixture, on the lower fixture Surface has been made into integration V-groove, and the upper fixture includes straight block；The straight block top inner face to top surface inner face is intilted Slope surface；It is longitudinal on the outside of the straight block to offer at least two convex-down through slots；It is logical that the lower fixture top surface offers face convex-down The lower opening of slot；Bolt is screwed between the convex through slot and lower opening.

As preferred embodiment, gasket is provided on the outside of the bolt；The gasket is connected in convex through slot transition Place.

As preferred embodiment, the upper fixture and lower fixture inner face laterally offer straight trough respectively；The straight trough Inside is fixed with transverse slat；Straight trough is protruded at the transverse slat both ends, and offers adjustment hole；Screw rod is screwed on the inside of the adjustment hole； The screw front end is fixed with bulb；The two bulb activities snap fit onto bull stick；Rotating cylinder is provided with outside the bull stick.

As preferred embodiment, the sum of the rotating cylinder outer diameter and horizontal plnk thickness are less than straight trough groove depth.

Compared with prior art, the crystal bar clamping tooling of the utility model；Upper fixture uses straight block simultaneously Cooperate the slope surface at the top of it to realize to compress, the crystal bar processing that can receive big outer diameter drives bulb by screw rod in positioning Driving bull stick is pushed forward, and so that rotating cylinder is protruded straight trough outer surface, rotation can be selected to adjust in crystal bar position fixing process, completes to position and pass through Screw rod back spin is driven rotating cylinder to return in through slot by direction finder monitoring, at this point, by the upper and lower fixture of bolt locking, can be sent to adding It is processed at work milling apparatus.
