Method of taking glass substrate

Abstract

The invention provides a method of taking glass substrate, which comprises the following steps of making a glass substrate aggregate overlapped with a plurality of glass substrates in a standing state; adsorbing and taking out one by one in order from the glass substrate of the outermost layer of the glass substrate aggregate; peeling off the glass substrate of the outermost layer from the vertical direction and taking out the glass substrate.

Description

technical field [0001] The present invention relates to a method for taking out glass substrates. A glass substrate assembly with a plurality of glass substrates stacked on top of each other is placed in a standing state, and the glass substrates located on the outermost layer of the glass substrate assembly are sequentially sucked and removed one by one. take out. Background technique [0002] Solar cells that convert sunlight directly into electricity are attracting attention as a clean energy source that prevents global warming. Among solar cells, a thin-film solar cell having a structure in which silicon is thinly deposited on a glass substrate is particularly attractive in that it uses less silicon and has a simpler structure than conventional solar cells. In addition, since thin-film solar cells can be reduced in size by increasing their size, glass substrates used in thin-film solar cells have been increasing in size. [0003] In the manufacturing process of thin-fi...

Problems solved by technology

[0006] However, as glass substrates become larger and thinner, adhesion tends to occur between the glass substrates or between the glass substrates and the spacer, and when the glass substrates are peeled off, the two sides are peeled off in the form of the glass substrate that is attached to the outermost layer. When taking out more than one glass substrate, the glass substrate attached to the target glass substrate will fall.

[0007] In addition, in order to prevent such sticking and take out one by one reliably, it takes a lot of time to peel off from the edge, so there is also a problem that the cycle time is long.
