A dust protection method for a glass substrate cutter, comprising the following steps:
- (1) providing a cutter and a glass-substrate-to-be-cut, wherein the cutter comprises a cutter body, a cutting blade mounted above the cutter body, a cover plate assembly mounted on the cutter body to correspond to the cutting blade, and suction tubes arranged at opposite sides of the cutting blade, the cutter body comprising a platform that bears the glass-substrate-to-be-cut thereon, the cover plate assembly and the cutting blade being arranged above the platform, the cover plate assembly forming a first slit corresponding to the cutting blade;
- (2) positioning and fixing the glass-substrate-to-be-cut on the platform and closing the cover plate assembly in such a way that a second slit is formed between the glass-substrate-to-be-cut and the cover plate assembly;
- (3) introducing a pressurized gas flow into the second slit at edges of the glass-substrate-to-be-cut and controlling the pressurized gas flow to blow toward the first slit, while at the same time making the suction tubes drawing in the gas;
- and
- (4) controlling the cutting blade to proceed with the cutting operation along the first slit to complete cutting of the glass substrate, where the particles generated during the cutting operation are either sucked away by the suction tubes or deposit on the cover plate assembly.

- (4) controlling the cutting blade to proceed with the cutting operation along the first slit to complete cutting of the glass substrate, where the particles generated during the cutting operation are either sucked away by the suction tubes or deposit on the cover plate assembly;
- wherein the cover plate assembly comprises two first cover plates, two second cover plates arranged between the two first cover plates, a frame fit over outer edges of the first and second cover plates, and a plurality of mounting posts mounted to two opposite sides of the frame, the first cover plates being conventional ordinary cover plates, the second cover plates being ordinary cover plates;
- wherein the first slit is located between the two second cover plates;
- wherein the second slit is of a size of 0.5-2 mm;
- wherein the second slit is of a size of 1 mm;
- wherein the cutter body comprises a robot corresponding to the glass-substrate-to-be-cut and an elevation mechanism corresponding to the cover plate, the robot functioning to carry out operations of picking up and positioning the glass substrate, the elevation mechanism comprising a groove formed in the platform and a driving motor arranged to correspond to the cover plate assembly, the cover plate assembly being receivable in the groove, the groove having sidewalls forming recesses corresponding to the mounting posts of the cover plate assembly, the recess comprising a horizontal channel and down channels formed at two ends of the horizontal channel;
- wherein when the robot moves the glass-substrate-to-be-cut to the platform or moves a cut glass substrate from the glass substrate, the robot extends to the platform, the mounting posts of the cover plate sliding up to the horizontal channel, whereby the robot, after completing the operation, is retrieved from the platform to allow the mounting posts of the cover plate to slide down into the down channels;
- and
- wherein the cutter body is a cutting wheel cutter body or a laser cutter body.
