Film peeling device
A film peeling device preventing deformation or other defect of substrates occurring in the process of conveying films adhered up to the substrate leading ends while peeling from the substrate, protecting the substrate from damage, and avoiding deterioration of the substrate quality. The constitution is composed of a substrate holding mechanism for holding the leading end of a substrate by linear contact, an adhering and peeling mechanism for peeling films by an adhesive force from the substrate held by the substrate holding mechanism, a film holding tool for gripping individually the leading ends of the films adhered to the substrate both sides being wound and lifted by the adhering and peeling mechanism, a film conveying unit drive mechanism for conveying the film holding tool gripping the films in the substrate opposite direction conveying direction, and a recovery container accommodating the films being gripped and conveyed by the film holding tool.
1. A film peeling device, being a film peeling device having substrate conveyer for conveying substrates, for peeling films adhered to both sides of the substrate being conveyed by the substrate conveying means, the film peeling device comprising:
a substrate holder for holding the leading end of the substrate by linear contact at edges of the leading end;
a peeler for peeling the films by an adhesive force from the substrate held by the substrate holder;
a film holder for gripping individually the leading ends of the films adhered to both sides of the substrate being wound and lifted by the peeler;
a film conveying unit driver for conveying the film holder gripping the films in an opposite direction of the substrate conveying direction; and
a recovery container for accommodating the films being gripped and conveyed by the film holder.
2. The film peeling device as set forth in claim 1 , wherein the substrate holder includes a block with a portion provided at an inclination angle to contact one of the edges of the leading end of the substrate.
3. The film peeling device as set forth in claim 1 , wherein the substrate holder comprises:
a first clamp provided with a first block; and
a second clamp provided with a second block positioned adjacent the first block, wherein
the first block and the second block are provided with opposing inclined faces to contact the edges of the leading edge, the opposing inclined faces sloping away from each other in a first direction opposite a second direction that the substrate conveyer is configured to convey the substrate.
