The invention relates to the field of integrated circuit manufacturing, and provides an integrated circuit tectorial membrane tearing mechanism. The integrated circuit tectorial membrane tearing mechanism comprises a fixation seat provided with a long groove, two carrier tape guide rails which are respectively disposed at the two sides of the long groove and are connected with the upper end of the fixation seat, a tectorial membrane collection box, a braided tape driving positioning device, a tectorial membrane tearing device and a strip breaking detection device. When the integrated circuit tectorial membrane tearing mechanism is used, a braided tape of an integrated circuit whose tectorial membrane needs to be torn is placed from the rear ends of the carrier tape guide rails and is arranged on the two carrier tape guide rails, the braided tape drives a positioning device braided tape to move forward to a tectorial membrane separating position, the tectorial membrane at the front end of the integrated circuit braided tape is separated in a hand-operated mode, and the tectorial membrane tearing device tears the tectorial membrane and sends the tectorial membrane to the tectorial membrane collection box for collection. The strip breaking detection device detects whether there are fractures in the tectorial membrane. The integrated circuit tectorial membrane tearing mechanism has quite high tectorial membrane tearing efficiency, and the integrated circuit is not easily damaged.
