  • Patent number: 10843955
    Abstract: A non-contact shaping device includes a first fixture including a fixing section structured to alternately blow out and suck in gas. The fixing section may fix, through suction of gas, a glass plate thereon. An optic heat source processing device is selectively set above predetermined portions of the glass plate to heat, in a non-contact manner, and thus soften, in a temperature-controlled manner, the portions for curving and suspending downward along an edge of the fixing section. The curved glass plate is then lifted up through blowing gas from the first fixture. The second fixture selectively covers the curved glass plate and blow gas therefrom to flow, in collaborative combination with the gas blown from the first fixture, around surfaces of the curved glass plate for cooling and fixing a shape of the curved glass plate in a non-contact manner to form a three-dimensional curve-surfaced glass product.
