Abstract
The utility model provides a kind of polishing clamp of the 3D glass containing through hole, including the matched chuck body in the concave surface with the 3D glass containing through hole or convex surface and the plunger being arranged in the mounting hole of chuck body, it is installed with plunger in through hole during polishing on 3D glass and after 3D glass is secured directly or indirectly in chuck body, the top surface of the plunger (2) is not less than the top surface of the 3D glass.The utility model one side carries out 3D glass because plunger is penetrated in through hole auxiliary and fixes and the polishing difficulty of 3D glass is reduced, and 3D glass is no longer easily flown out under conditions of high speed polishing beyond polishing clamp.On the other hand because of the stop of plunger so that the hole edge of 3D glass through holes is no longer easily polished to sweep and grinds and must collapse, thus products obtained therefrom fully achieves production quality requirement, and glass processing yield is high.
Description
Technical field
The utility model belongs to 3D panel manufacture fields before and after mobile phone glass, more particularly to a kind of 3D glass containing through hole
Polishing clamp.
Background technology
3D glass refers to the glass of the curved surface containing multiple and different bending directions, common 3D glass for four sides are bent and in
The heart is the curved 3D glass in four sides of plane.Through hole is not all contained on the 3D glass panels most begun to use, simply in glass panel (tool
Body is to be used as cell phone back cover) concave surface on ink for screen printing when reserve one or more transparent poroid patterns and be not provided with ink, example
Such as it is left white in shooting hole site and flash lamp position, realizes holeless camera function.And as people are for mobile phone photograph quality
It is required that continuous improvement, this mode taken pictures through 3D glass back-covers constrains the imaging function of high definition optical lens significantly,
Fashion trend will be become by thus opening up the 3D curved-surface structures glass of through hole.At present 3D bend glasses Mobile telephone front panel or after
The through hole opened up on back-cover plate includes single shooting through hole, double shooting through holes, button through hole, fingerprint through hole, flash lamp through hole, receiver
Through hole etc., the shapes of these through holes is for example, square, circular, kidney-shaped, strip etc..
This 3D glass containing through hole is obtained, preparation process of the prior art successively includes：Finishing impression shape, hot bending into
Type, polishing, finishing impression reaming, cleaning, middle inspection, plated film and packaging shipment.In this scheme, be first to finishing impression shape and hot bending into
Finishing impression reaming on the glass of 3D glass polishings again after a polish after type.Such scheme has following lack in actual mechanical process
Point：
1st, first polish finishing impression reaming again and drawn so that be easy to causeing glass during finishing impression reaming forms the through hole
Wound and fixture crush, thus it is low to process yield.
2nd, when preparing relatively thin 3D glass, because of vacuum adsorption force deficiency during high speed polishing so that 3D glass produces
Product are easy to fly out from fixture, further increase glass preparation difficulty or reduce glass processing yield.
If but when by the way of first finishing impression reaming re-polishing, because the polishing of 3D glass belongs to unlike flat glass
Mirror polish, and 3D glass polishings substantially belong to a polishing, such as the flexure plane of four evaginations of the curved 3D glass in four sides and one
Plane needs to polish at the same time in same polishing clamp.The removal amount of point polishing is much larger than mirror polish, thus this is to through hole
Influence is very big, and the hole edge for the through hole that can form finishing impression in polishing, which be swept, collapses, and is thus difficult to meet to lead to during film fitting
Bore edges coincide smooth effect, it is also difficult to meet mobile phone camera and flash unit is bumped into very close to each other after lead to the hole site reach
To the effect of one integrated mass so that the 3D glass of the through hole containing turned-down edge can only cancel processing.
Therefore, this area needs a kind of preparation method of the new 3D glass containing through hole, and corresponding this area also needs to one
The new polishing clamp of kind.
