Abstract

A laminated substrate separating device used for separating a first substrate from a second substrate of a laminated substrate is provided. The first and the second substrates are misaligned at an edge of the laminated substrate. The laminated substrate separating device includes a base where the laminated substrate is disposed thereon, and a separating tool movably disposed on the base along an axis. The separating tool presses a portion of the first substrate being exposed out of the second substrate at a misaligned edge such that a gap is formed between the first and the second substrates. The separating tool inserts into the gap at the misaligned edge to press the first substrate, such that the second substrate is separated from the first substrate. A method for separating laminated substrate is also provided.

First claim

2 . The laminated substrate separating device as claimed in claim 1 , further comprising:
a roller, movably disposed on the base along the axis, and having a plurality of first holes, wherein a portion of the second substrate separated from the first substrate is vacuumed to the first holes and rolled up by the roller.

3 . The laminated substrate separating device as claimed in claim 2 , further comprising:
a supporting member, disposed beside the roller, wherein the portion of the second substrate separated from the first substrate is rolled up by the roller and is movably clamped between the supporting member and the roller.

4 . The laminated substrate separating device as claimed in claim 3 , wherein the supporting member is another roller.

5 . The laminated substrate separating device as claimed in claim 4 , wherein the another roller is rotatable and revolvable around to the roller.

6 . The laminated substrate separating device as claimed in claim 3 , wherein the supporting member is a clamping block disposed beside the roller and rotatable relative to the roller, the clamping block has a contact surface, the second substrate is movably clamped between the contact surface and the roller, and a surface contour of the contact surface and a surface contour of the roller are complementary.

7 . The laminated substrate separating device as claimed in claim 3 , wherein the supporting member is a driving pulley set.

8 . The laminated substrate separating device as claimed in claim 1 , further comprising:
a moving fixture, movably disposed above the base to move close to or away from the base, wherein the portion of the second substrate separated from the first substrate is attached to the moving fixture, such that a portion of the second substrate that is not separated from the first substrate moves away from the base along with the moving fixture, so as to separate from the first substrate.

9 .
