Apparatus and method for eliminating stress spots on a surface of glass

A method for eliminating stress spots on a surface of glass, characterized by comprising:

• a conveying step, the glass being conveyed to between an upper air-blowing assembly and a lower air-blowing assembly by a conveying assembly during a quenching and tempering period of the glass;
• a glass swinging step, the glass swinging reciprocally under an action of the conveying assembly along a conveying surface;
• and
• an air-cooling step, the upper air-blowing assembly blowing reciprocally along a width direction of an upper surface of the glass, the lower air-blowing assembly blowing reciprocally along a width direction of a lower surface of the glass,
• wherein the conveying assembly comprises:
• a conveying supporting-frame;
• a plurality of conveying rollers, rotatably mounted on the conveying supporting-frame;
• and
• an arc-transforming mechanism, used for transforming the conveying supporting-frame into a circular arc in shape, so as to form a circular-arc-shaped conveying surface on the plurality of conveying rollers;
• wherein the lower air-blowing assembly comprises:
• a plurality of air-fence supporting-frames, connected to the conveying supporting-frame;
• a plurality of air-fence plates, rotatably mounted on the plurality of air-fence supporting-frames, provided with a plurality of air blowholes, used for guiding air to blow to the conveying surface;
• and
• a swing driving mechanism, driving the air-fence plates to reciprocally swing along the swinging direction;
• wherein the arc-transforming mechanism comprises:
• a plurality of arc-transforming plates;
• and
• an arc-transforming-plate driving part, used for driving the plurality of arc-transforming plates to rotate,
• wherein two adjacent arc-transforming plates are hinged to each other, the plurality of conveying rollers are pivoted to the plurality of arc-transforming plates, each of the plurality of air-fence supporting-frames are connected to each of the plurality of arc-transforming plates, and two adjacent air-fence supporting-frames are connected through a universal joint;
• wherein the arc-transforming-plate driving part comprises:
• a sprocket, pivoted to each of the plurality of air-fence supporting-frames;
• a sprocket shaft, synchronously connected to the sprocket;
• and
• a sprocket-shaft driving part.
