发明名称 SHEET CUTTING PIN
摘要 The present invention relates to a sheet cutting pin capable of easily discharging a sheet chip from an optical sheet and the cutting pin by bending the sheet chip cut out of the optical sheet constituting a backlight unit of a light emitting diode (LED) when the optical sheet is punched as a bending part is provided in a radial direction of a blade of a sheet cutting pin. According to the present invention, the sheet cutting pin includes a body part, a blade, and a bending part. The blade protrudes downward along the circumference of a lower end of the body part so that the sheet is cut out in the shape of a circumferential surface of the body part. The bending part is provided inside the blade, and has a plate having a width corresponding to a connection length between both sides of the blade and having a predetermined height in a longitudinal direction of the body part so that a portion of the sheet cut out by the blade is bent. In the sheet cutting pin according to the present invention configured with the feature, the sheet chip cut out of the sheet by the cutting blade is not attached to the sheet, but can be easily discharged out when the sheet is cut by the cutting pin, so that a failure rate formed as the sheet chip is attached to the sheet is reduced, so the productivity can be improved.
