Embodiment 1
[0050] like figure 1 As shown, a curved glass forming device includes:
[0051] Laser (including laser control) system, beam shaping system, scanning galvanometer, upper and lower curved surface forming molds, glass temperature feedback device;
[0052] Laser control is connected with the laser, mainly controlling laser power, laser switching and adjusting process parameters, etc.;
[0053] For the above lasers, choose CO with a laser wavelength of 10.6 μm 2 laser;
[0054] The above-mentioned beam shaping system may include a beam expanding lens or a shaping lens group to expand and collimate the laser beam or shape the spot into a circle, ellipse, square, rectangle or other shapes;
[0055] The above-mentioned light spot shaped by the beam shaping system can be circular, square, rectangular or other shapes, preferably a rectangular light spot;
[0056] The above-mentioned scanning galvanometer is also called a laser galvanometer, which is composed of an X-axis or Y-axis ...
Embodiment 2
[0071] The structure is the same as that of Example 1. In Example 2, the scanning galvanometer is adjusted to the bottom, that is, the laser beam is irradiated from bottom to top, and the laser beam passes through the lower mold to heat and soften the glass. Other process flow is identical with embodiment 1. The principle and structure of the specific implementation are as follows: Figure 5 shown.
[0072] As can be seen from the above, the present invention has the following advantages:
[0073] 1. Compared with the traditional scheme, the present invention uses laser beam irradiation to heat and soften the glass, which has many advantages such as adjustable heating rate, high efficiency, energy saving, and controllable heat distribution.
[0074] 2. The glass temperature feedback device monitors and feedbacks the temperature, and the heating temperature has high precision, so as to avoid glass cracking caused by uneven heating.
[0075] 3. Germanium glass is used as the ...
