A sapphire crystal with a glass fixing strip is fixedly bracketed in an assembling groove in the middle of the fixed bracket, a screw hole is arranged on the side surface of the fixed bracket, a fixing screw is arranged in the hole and abutted with the side surface of the sapphire crystal, a positioning table is processed at an upper opening of the assembling groove, the connecting part is disposed on the positioning table and consists of a connecting seat and a connecting block, the lower surface of the connecting block is bonded on the upper surface of the glass fixing strip to form a bonding surface, the upper surface of the connecting block is fixed on the bottom surface of the connecting seat, a tensioning screw and an abutting screw are bracketed at the bottom of the connecting seat, a landing edge is processed on the outer side of the upper end of the connecting seat, lapped on the positioning table of the fixed bracket and fixed via the fixing screw, a cover plate is covered at the upper opening of the fixed bracket and pressed on the connecting seat, a batten is pressed on the cover plate, two ends of the batten are fixed on the upper sides of the side surface of the fixed bracket via screws, and a gasket is arranged at one end of a surface of the crystal which contacts with the fixed bracket.

Description

Sapphire crystal axial location adhering device

Technical field

The utility model belongs to the sapphire crystal technical field of processing equipment, relates to a kind of sapphire crystal axial location adhering device.

Background technology

Sapphire crystal in process of manufacture, at first to be processed into one regular cylindrical, afterwards columniform crystal is cut into slices, be processed into the sapphire wafer product.Add man-hour, require columniform axially and the crystal orientation of crystal a fixing angle is arranged, wafer radially with columniform axially perpendicular.Before the slice processing of carrying out crystal, will be at columniform crystal on side face adhering glass fixed strip, during cutting, columniform crystal is cut off and glass fixing strip is not cut off, to prevent that wafer from coming off, breaking into pieces from cylinder in cutting process, the upper surface of glass fixing strip is a plane, is used to bond to the connector of cutting machine.Because small error can appear in crystal columniform fixed angle axial and crystal orientation in being processed into columniform process, in the time of on the connector that glass fixing strip is bonded to cutting machine, need to regulate the gap of its bonding plane, to reduce the error of angle axially and between the crystal orientation of crystal of cylindrical crystal.At present, in actual production, owing to lack special-purpose sapphire crystal axial location adhering device, columniform crystal can't be adjusted bonding gap on bonding to the connector of cutting machine the time, has influenced the quality of sapphire wafer.

Summary of the invention

The utility model is in the prior art, columniform sapphire crystal is on bonding to the connector of cutting machine the time, lack special equipment, bonding gap can't be adjusted, cause cylindrical crystal axially with the crystal orientation of crystal between the angle existence than mistake, influence the problem of sapphire wafer quality, a kind of sapphire crystal axial location adhering device is provided, this device technique scheme is as follows:

Sapphire crystal axial location adhering device, by fixed mount, connector and fixture are formed, be installed with the sapphire crystal of band glass fixing strip in the fitting recess at fixed mount middle part, the side of fixed mount has screw, hold-down screw is housed in the hole, screw withstands on the sapphire crystal side, upper shed place of fitting recess is processed with positioning table, connector is installed on the positioning table, connector is made up of Connection Block and contiguous block, and the lower surface bonds of contiguous block forms a bonding plane on the upper surface of glass fixing strip, the upper surface of contiguous block is fixed on the bottom surface of Connection Block, the bottom of Connection Block is equipped with stretching screw and is held out against screw, and the outside, upper end is processed with scrap (bridge), and scrap (bridge) is overlapped on the positioning table of fixed mount, fix with hold-down screw, a cover plate is stamped in upper shed place of fixed mount, and cover plate is pressed on the Connection Block, is pressed with press strip on the cover plate, the two ends of press strip are screwed above the side of fixed mount, and the pad pad is at an end of crystal and fixed mount contact-making surface.

Adopt technique scheme, before on the connector that glass fixing strip is bonded to cutting machine, to columniform axially and the error of the angle between the crystal crystal orientation measure, and be labeled on the end face of crystal.When bonding, with the pad pad at side and bottom surface one end that crystal contacts with fixed mount, make the axial generation little deviation of the axial and cutting machine connector of crystal, this deviation just in time proofread and correct columniform axially and the error that exists between the crystal orientation of crystal, upper surface location with glass fixing strip pastes on the lower surface of fixed block afterwards, because the lower surface of fixed block is parallel with the bottom surface of fixed mount, after the axial process pad place mat of crystal is adjusted, inhomogeneous situation appears in the gap between glass fixing strip upper surface and the fixed block lower surface, this gap just in time makes crystal axis obtain adjusting to the deviation that occurs, reduced the error of angle axially and between the crystal crystal orientation of cylindrical crystal greatly, guarantee to cut radially conforming to quality requirements of back wafer, improve the crudy of wafer greatly.
