Description

Flake separation device

Technical Field

The utility model relates to the technical field of display device production, in particular to a sheet separation device.

Background Art

OCA optical adhesive is one of the raw materials for the touch screen of display devices. It is a double-sided adhesive without a matrix material. With the increasing mass production of OCA optical adhesive machines, the absorption problem of OCA optical adhesive has gradually become prominent.

In the prior art, a cylinder is used to push the loading platform, and the conveying arm reaches the set position to absorb the OCA optical glue. After the conveying arm absorbs the material on the top layer, it is shaken up and down by the shaking cylinder on the conveying arm to shake off the excess OCA optical glue. Then the conveying arm is moved to the stacking detection position to perform stacking detection. After the detection is no problem, the film peeling and bonding operation is performed. Since the shaking cylinder shakes vertically, the conveying arm will be unevenly stressed, shortening the service life of the conveying arm, and the conveying arm will be deformed. When it descends to absorb the OCA optical glue, it is easy to cause the OCA optical glue to deform, affecting the subsequent bonding. The electrostatic adsorption of the material is too large, and the conveying arm cannot separate the OCA optical glue due to shaking. If the detection at the stacking detection position fails, the shaking action needs to be repeated, affecting production efficiency.

The plane where one of the right angle sides of the separation hand in the right triangle shape is located is connected to the separation base column, and the plane where the other right angle side is located is set downward, and the upper surface of the separation hand is an inclined surface, so that the side of the pressing separation hand 24 pressing the sheet 100 located below is a plane, and the volume of the accommodating cavity of the separation hand gradually decreases from the end away from the sheet 100 to the end close to the sheet 100, so that the greater the wind force blown out from the air outlet 203, the easier it is to separate two adjacent sheets 100.
