Abstract:
1. A method for separating a liquid crystal panel and a liner pad, comprising the following steps: (1) providing a separation machine and a combination of the liquid crystal panel and liner pad to be separated, the separation machine comprising a control device, a position detection device electrically connected to the control device, and a separation device electrically connected to the control device, the separation device comprising a suction device, a plurality of air blasting devices, and a plurality of shaking devices, the suction device comprising a first suction unit, the first suction unit comprising a first connection bar, a central suction arm mounted to a center of the first connection bar and having a free end that extends away from the first connection bar, a plurality of first suction arms mounted to the first connection bar on both sides of the central suction arm and each having a free end that extends away from the first connection bar, and a central suction nozzle and first suction nozzles respectively mounted to the free ends of the central suction arm and the first suction arms, the central suction nozzle and the first suction nozzles being arranged to face downward, the central suction nozzle being set at a height lower than that of the first suction nozzles; (2) the control device controlling the suction device to move toward the combination of the liquid crystal panel and liner pad to be separated and meanwhile, the position detection device detecting, in a real time manner, a moving position of the suction device and transmitting data of the detected moving position to the control device, the control device controlling moving speed of the suction device according to the data of moving position; (3) the central suction nozzle first contacting and sucking the liner pad of the combination of the liquid crystal panel and liner pad to be separated, and subsequently the first suction nozzles contacting and sucking the liner pad of the combination of the liquid crystal panel and liner pad to be separated; (4) the control device controlling the shaking devices to shake in order to subject the combination of the liquid crystal panel and liner pad to be separated to vibration and the control device controlling the air blasting devices to eject air streams to a side edge of the combination of the liquid crystal panel and liner pad to be separated; and (5) after being subjected to vibration and air streams, the liner pad of the combination of the liquid crystal panel and liner pad to be separated being separated from the liquid crystal panel.
