Abstract
A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.
Claims21
A machine for removing protective cover glass from a display unit having a cover glass, an electronic display portion, and an intermediate layer sandwiched therebetween, said intermediate layer defining a first plane between the layer and the glass and a second plane between the intermediate layer and the electronic display portion, the machine comprising:
- a housing;
- a carrier for holding the display unit, said carrier configured to hold said unit without blocking access to said intermediate layer;
- a slideable interface interposed between the housing and carrier for moving the carrier relative to the housing;
- a pair of first and second guides connected to said housing and located on either side of the carrier;
- and
- a cutting element configured to travel in a path from one guide to the other in a third plane, said guides are located below said second plane so that said cutting element is biased to engage said intermediate layer at said second plane;
- wherein said cutting element is aligned between said first and second planes to cut through said intermediary layer and separate the glass from the electronic display element.

- a slideable interface interposed between the housing and carrier for moving the carrier relative to the housing;
- a pair of first and second guides connected to said housing and located on either side of the carrier;
- and
- a flexible wire cutting element configured to travel reciprocally in a path from one guide to the other in a third plane, said guides being located offset from said second plane so that said cutting element is biased to engage said intermediate layer adjacent said second plane;
- wherein said cutting element is aligned between said first and second planes to cut through said intermediary layer and separate the glass from the electronic display element.
