Description

Airbag type negative pressure cage peeling device structure

The invention relates to a structure of a bag-type negative pressure net box stripping device, which belongs to the technical field of soft glass substrate peeling glass substrate working of a soft touch panel or a soft display panel.

Today's soft touch panel or flexible display panel line is made of soft, flexible and high temperature resistant polyimide film (Poyimide referred to as PI), (first figure) first with polyimide film 10 ( The poyimide abbreviated as PI) is adhered to a glass substrate 20, and then formed on the surface of the polyimine film 10 (poimimide referred to as PI) by sputtering technology to form an electronic circuit, that is, a flexible circuit substrate 100 (second drawing), The flexible wiring board 100 is attached to the glass substrate 20, and is required to cut the outer wiring of the flexible wiring board 100, remove the scrap 101, and peel off the flexible wiring board 100.

However, the flexible circuit board 100 is easily damaged during the peeling operation, and the problem of an increase in manufacturing cost is invisible.

In view of the above, the damage caused by the stripping work of the aforementioned flexible circuit substrate needs to be improved, so the creator has been continuously researched and improved according to the experience of the industry for many years, and finally obtains a refined structure.

As for the structure, purpose, method and spirit of this creation, members of the Board of Directors can fully understand the creator by referring to the following drawings and explanations.

The structure of the airbag type negative pressure net box stripping device refers to a structural device capable of gradually peeling off the flexible circuit substrate from the glass substrate and preventing the flexible circuit substrate from being damaged, and comprises a negative pressure box, which is a housing having an opening. There is a vacuum suction hole, and an air bag is arranged in the space of the negative pressure box, and the opening of the negative pressure box is combined with an omentum to form a negative pressure net box peeling device, which can inflate the air chamber of the air bag of the pressure box space to form an expanded top pressure The omentum is in full contact with the flexible circuit substrate, and the vacuum suction hole is used to vacuum the negative pressure box space, so that the net film forms an adsorption force, adsorbs the soft circuit substrate, and slightly rises the negative pressure net box stripping device, and the soft circuit substrate is surrounded by the outer edge thereof. The glass substrate is gradually peeled off from the middle, and the air knife is used to assist the peeling speed to achieve the effect of preventing damage of the flexible circuit substrate.

The main purpose of this creation is to inflate the airbag chamber of the negative pressure box space of the negative pressure cage peeling device, form a full contact between the expanded top pressure mesh membrane and the flexible circuit substrate, and then vacuum the vacuum suction hole to vacuum the vacuum box space. The omentum forms an adsorption force to adsorb the flexible circuit substrate, and slightly rises the negative pressure net box peeling device, and the flexible circuit substrate gradually peels off the glass substrate from the outer edge thereof to the center, thereby preventing the damage of the soft circuit substrate.
