Description

Membrane separation mechanism

This case relates to a membrane separation mechanism, in particular a membrane separation mechanism having an air blowing member.

A copper foil separation mechanism common in the industry has a cutting plate (such as a string). The cutting board is moved from the side of the printed circuit board toward the opposite side of the side, thereby cutting the copper foil on the printed circuit board. However, in the process of cutting the copper foil of this cutting board, it is easy to leave a small part of the copper foil on the printed circuit board, thereby affecting the electrical conduction of the printed circuit board.

In addition, another copper foil separation mechanism commonly used in the industry has an elastic stripper and a clamp. After the stripper lifts off the corners of the copper foil on the side of the printed circuit board, the clamp holds the corners of the copper foil and moves toward the opposite side of the side, thereby tearing off the copper foil on the printed circuit board. When the jig moves toward the opposite side, the copper foil on the printed circuit board is easily torn, and the remaining part of the copper foil affects the electrical conduction of the printed circuit board.

In view of the above problems, the present invention provides a film separation mechanism suitable for a carrier plate having at least one film. The thin film separation mechanism includes a film raising member, an air blowing member, a pneumatic member, and a control unit. The film raising member is used to separate the corner of the film from the carrier plate. The air blowing member has a nozzle, and the nozzle conveys gas in the gap between the corner of the separated film and the carrier plate. When the gas flows diagonally from one of the corners of the separated film, the rest of the film is separated from the carrier plate. Pneumatic component When driven, delivers gas to the nozzle. The control component is adapted to drive the film raising member to separate the corners of the film located on the carrier plate, and to drive the pneumatic member to transport the gas out of the nozzle. Therefore, the blowing member of the present case can separate the rest of the film except the corner of the film from the carrier plate by transporting the gas.

The present invention further provides a film separation mechanism, which is suitable for a carrier plate having at least one film. The thin film separation mechanism includes a film raising member, an air blowing member, a pneumatic member, a cutter, and a control unit. The film raising member is used to separate the corners of the film from the carrier plate. The blowing member has a nozzle that transports gas in the gap between the corner of the separated film and the carrier plate, and when the gas passes through a part of the film on the carrier plate, a part of the film is from the carrier plate Separation. When the pneumatic component is driven, it delivers gas to the nozzle. The cutting knife is located between a part of the separated film and the carrier plate, and moves toward a moving direction to separate the rest of the film located on the carrier plate. The moving direction is the opposite corner of the separated corner. The control unit drives the pneumatic member to transport the gas out of the nozzle, and drives the nozzle and the cutter to move in the moving direction. Therefore, the blowing member and the cutter of the present case can separate the film corner portion and the rest of the film other than a part of the film from the carrier plate.
