This application pertains to carrier processing equipment, specifically a film-tearing machine, used to automatically tear the film from the upper surface of annular sheet-shaped carriers. During film tearing, a blocking part and a second pressure claw provide a counterforce on the upper side of the carrier, allowing the top block to smoothly separate the film from the carrier and form an insertion port when pushing the first end of the film from the inner ring side. Subsequently, the first pressure claw presses against the middle of the first end of the carrier through the insertion port, and the second pressure claw retracts, ensuring that the carrier is pressed tightly during the film tearing process. The gripper holds the first end of the film and pulls it towards the end. When it approaches the top block, the second pressure claw presses against the carrier again from both sides to provide sufficient downward pressure to cope with the increased tearing force. At the same time, the top block moves down to avoid the gripper, ensuring smooth traction without interference. When the gripper moves to the vicinity of the end of the carrier, the blocking part moves away from above the end, allowing the film to completely detach. All structures work together to complete automated film tearing, replacing manual operation and improving film tearing efficiency and carrier recovery convenience.
