Description

Technical Field

[0001] The invention belongs to the technical field of polarizer attachment, and in particular relates to a polarizer attachment machine for a liquid crystal display screen. Background Art

[0002] Polarizer is an optical film composed of multiple layers of polymer materials that has the function of generating polarized light.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. Place the polarizer in the alignment groove, with the film side of the polarizer facing outward. The polarizer is adsorbed on the movable plate by the Bernoulli suction cup, and then the tape is pasted on the edge of the polarizer at the outer end of the movable plate. The tape needs to exceed the edge of the polarizer. Place the excess tape between the clamping plate and the upper end surface of the clamping notch, clamp the tape, and then the central axis drives the film tearing roller to rotate clockwise. The film tearing roller pulls the tape downward, and the tape tears the film of the polarizer and gradually wraps around the film tearing roller;

[0018] 2. The transmission gear drives the transmission rack to move forward, the transmission rack drives the supporting strip to move forward, the supporting strip drives the placing plate and the movable plate to move forward, at this time the film tearing shovel is between the polarizer and the film, so that the polarizer and the film can be separated more conveniently;

[0019] 3. When the end of the movable plate moves to the upper end of the docking rail, the rotating shaft drives the supporting baffle to rotate 180 degrees. At this time, the movable plate flips downward under the action of gravity, and the movable plate fits on the inclined surface of the upper end of the side plate. Then the Bernoulli suction cup is controlled to disconnect. At this time, the polarizer falls between the side plates on the docking rail, and the polarizer bends at the arc surface of the docking rail, fits on the docking rail and slides down. The front end of the polarizer contacts the inner wall of the positioning baffle, and the front end of the polarizer is automatically aligned with the front end of the display substrate.

[0020] 4. The mounting seat drives the docking rail to move, and the docking rail drives the sliding block, the second connecting rod and the magnetic block to move. When the magnetic block moves to the magnetic strip, the magnetic block is attracted to the magnetic strip, and the magnetic block drives the second connecting rod and the sliding block to move downward. The sliding block drives the first connecting rod and the pressure plate to move downward, and at this time the pressure plate just presses the positioning baffle, so that the positioning baffle is completely in the vertical groove. Therefore, the pressure plate gradually presses the polarizer and the display substrate from the beginning of the display substrate, and at the same time, the polarizer gradually slides down from the docking rail and gradually contacts with the display substrate until the polarizer and the display substrate are completely fitted.
