Method for cleansing glass substrate and device for performing the method

摘要

The present invention provides a method for cleansing a glass substrate and a device for performing the method. The method includes: (1) providing a transport platform (20) and a glass substrate to be cleansed (40); (2) placing a glass substrate to be cleansed (40) on the transport platform (20); (3) providing two air blowing devices (60); (4) the two air blowing devices (60) blowing air flows toward the lass substrate to be cleansed (40) to have impurities (42) that are attached to the glass substrate to be cleansed (40) detached from the glass substrate (40); (5) providing a suction device (80), the suction device (80) comprising an air drawing device (82) and a magnetic attraction device (84); (6) the air drawing device (82) drawing air from the glass substrate to be cleansed (40) and the magnetic attraction device (84) generating a magnetic attraction force to magnetic impurities on the glass substrate to be cleansed (40) so as to draw the impurities (42) attached to the glass substrate to be cleansed (40) into the suction device (80).

1. A method for cleansing a glass substrate, comprising the following steps:
(1) providing a transport platform and a glass substrate to be cleansed, the glass substrate to be cleansed having impurities attached thereto, the impurities comprising magnetic impurities and non-magnetic impurities; (2) placing the glass substrate to be cleansed on the transport platform; (3) providing two air blowing devices, the two air blowing devices being spaced from each other and arranged above the transport platform; (4) the two air blowing devices blowing air flows toward the glass substrate to be cleansed to have the impurities that are attached to the glass substrate to be cleansed to detach from the glass substrate; (5) providing a suction device, wherein the suction device comprises an air drawing device and a magnetic attraction device, the air drawing device comprising an air drawing opening arranged between the two air blowing devices, the magnetic attraction device being arranged inside the air drawing opening of the air drawing device; and (6) the air drawing device drawing air from the glass substrate to be cleansed by creating an airflow moving into and through the air drawing opening to carry the impurities entraining the airflow into the air drawing opening and the magnetic attraction device generating a magnetic attraction force inside the air drawing openings to attract the magnetic impurities from the glass substrate to be cleansed so as to draw the impurities attached to the glass substrate to be cleansed into the suction device.
