Description
本發明與玻璃成型設備有關,特別是指一種非接觸的玻璃成型設備。The present invention relates to glass forming equipment, in particular to a non-contact glass forming equipment.
目前曲面玻璃成型設備包括加熱器、模具及成型滾筒。目前,曲面玻璃的成型方式是先將被加工玻璃放在模具上,此時,被加工玻璃是平面的。接著,對模具及被加工玻璃進行加熱,以使被加工玻璃軟化而可型塑外形。然後,透過成型滾筒直接接觸及施壓於被加工玻璃的表面,以使被加工玻璃順應模具的表面起伏變化形成對應的曲面。Current curved glass forming equipment includes heaters, molds and forming rollers. At present, the forming method of curved glass is to first place the processed glass on the mold, and at this time, the processed glass is flat. Next, the mold and the processed glass are heated to soften the processed glass and form a shape. Then, it directly contacts and presses the surface of the processed glass through the forming roller, so that the processed glass conforms to the surface undulations of the mold to form a corresponding curved surface.
目前這種型塑方式需要靠成型滾筒直接接觸並滾動按壓被加工玻璃的表面,以使被加工玻璃暫時地貼合模具表面,但因為需要直接接觸,因此,塑型過程中容易在被加工玻璃的表面上產生壓痕、髒污或其他汙染,而影響曲面玻璃的品質。At present, this kind of molding method needs to rely on the forming roller to directly contact and roll the surface of the glass to be processed, so that the processed glass temporarily fits the mold surface, but because of the need for direct contact, it is easy for the glass to be processed during the molding process. Indentation, dirt or other pollution on the surface of the glass will affect the quality of the curved glass.
另一種方式是將被加工玻璃在模具上,接著透過加熱方式使被加工玻璃軟化而自然順應模具的形狀,這種方式雖然不需要接觸,但不易控制被加工玻璃地彎曲程度,因此,這種成型方式的良率較差,且不利於量產。Another way is to put the processed glass on the mold, and then use heating to soften the processed glass and naturally conform to the shape of the mold. Although this method does not require contact, it is not easy to control the degree of bending of the processed glass. Therefore, this The molding method has poor yield and is not conducive to mass production.
有鑑於上述缺失,本發明的曲面玻璃成型設備透過熱氣流來讓被加工玻璃能貼合模具的起伏表面,以避免被加工玻璃表面留下髒污、壓痕或其他汙染。In view of the above-mentioned shortcomings, the curved glass forming equipment of the present invention allows the processed glass to fit the undulating surface of the mold through hot air flow, so as to avoid dirt, indentation or other pollution on the processed glass surface.
本發明的曲面玻璃成型設備包括模具及成型裝置。模具包括前側邊、後側邊、左側邊、右側邊、起伏表面及兩導引路徑。起伏表面自前側邊向後側邊延伸,且供承載已被預熱的玻璃片。兩導引路徑分別位在左側邊及右側邊。成型裝置可沿著兩導引路徑移動,且有供氣平面正對起伏表面,並與已被預熱的玻璃片保持間隔。成型裝置的供氣平面可對已被預熱的玻璃片提供正壓熱氣流,以使已被預熱的玻璃片暫時地貼合在起伏表面上。The curved glass forming equipment of the present invention includes a mold and a forming device. The mold includes a front side, a rear side, a left side, a right side, an undulating surface and two guiding paths. The undulating surface extends from the front side to the rear side and supports the preheated glass sheet. The two guiding paths are located on the left and right sides respectively. The forming device can move along two guiding paths, and the air supply plane faces the undulating surface and keeps a distance from the preheated glass sheet. The air supply plane of the forming device can provide positive pressure hot air flow to the preheated glass sheet, so that the preheated glass sheet is temporarily attached to the undulating surface.
其中,成型裝置可沿著兩導引路徑移動包括成型裝置相對模具運動或模具相對成型裝置運動。Wherein, the molding device can move along the two guiding paths including the movement of the molding device relative to the mold or the movement of the mold relative to the molding device.
如此,本發明的曲面玻璃成型設備可透過熱氣流讓已被預熱的玻璃片暫時地貼合在起伏表面上,來避免接觸所產生各種問題。In this way, the curved glass forming equipment of the present invention can temporarily attach the preheated glass sheet to the undulating surface through the hot air flow, so as to avoid various problems caused by contact.

圖3及圖4分別是熱風供應器131的底視示意圖。多個氣孔13113是間隔排列而形成一直線,如圖3,多個氣孔13113也可以是陣列排列,如圖4,如此,氣孔13113所形成的直線將有三條。間隔排列的氣孔13113可使氣流不會如傳統滾筒作業在被加工玻璃的表面產生線接觸的局部大應力。3 and 4 are schematic bottom views of the
請再參照圖2所示,左側導引輪組133及右側導引輪組135分別連接熱風管1311,且左側導引輪組133及右側導引輪組135的部分輪面1331、1351略凸伸出熱風管1311的供氣平面13111。左側導引輪組133及右側導引輪組135的輪面1331、1351是沿著導引路徑1133移動,以使供氣平面13111與起伏表面1119保持間隔。Please refer to Figure 2 again, the left
請再參照圖1所示,保持器137連接熱風供應器131,以使左側導引輪組133及右側導引輪組135的輪面1331、1351保持接觸兩導引板113的頂面1131,如此,供氣平面13111與起伏表面1119之間的間隔可以維持大致一致,且熱氣吹拂的氣壓也可較為一致。Please refer to FIG. 1 again, the
本實施例中,保持器137包括兩旋轉缸1371及兩懸臂1373。兩懸臂1373分別連接兩旋轉缸1371及熱風管1311,旋轉缸1371用以帶動懸臂1373,以使左側導引輪組133及右側導引輪組135的輪面1331、1351可以保持接觸兩導引板113的頂面1131。In this embodiment, the
另一實施例中,如圖5所示,保持器137a包括伸縮缸1371a及固定架1373a。伸縮缸1371a連接固定架1373a。固定架1373a連接熱風管1311a,伸縮缸1371a用以帶動固定架1373a,以使左側導引輪組133a及右側導引輪組135a的輪面可以保持接觸兩導引路徑1133a(如圖中虛線)。In another embodiment, as shown in FIG. 5, the
於此實施例中,模具110a僅有本體111a,而省略導引板,換言之,導引路徑1133a是可以被規劃在本體111a上。In this embodiment, the
雖然,上述以兩種保持器137、137a來做說明,但其他實施例中,保持器也可以使用其他方法或裝置來使左側導引輪組133及右側導引輪組135的輪面1331、1351保持接觸兩導引板113的頂面1131。Although the two types of
本發明的曲面玻璃成型設備的組成及結構如上所述,隨後說明其運作及功效。The composition and structure of the curved glass forming equipment of the present invention are as described above, and its operation and effects will be described later.
如圖6-8所示,曲面玻璃成型方式是先將被加工玻璃預熱至可塑型的狀態,隨後稱這種狀態的玻璃是已被預熱的玻璃片300,已被預熱的玻璃片300放置於模具上,也就是放在起伏表面1119上。其中,被加工玻璃可以放於模具上進行預熱,或者,先預熱再放置於模具上。此外,塑型前,放在起伏表面1119上的已被預熱的玻璃片300是沒有貼合起伏表面1119,特別在彎曲的表面更是明顯。As shown in Figure 6-8, the curved glass forming method is to preheat the processed glass to a plastic state, and then call the glass in this state the
此外,圖6-8中雖僅繪示左側導引輪組133,但透過前述說明可知,右側導引輪組135的結構、功能及運作是與左側導引輪組133相同,因此,省略右側導引輪組135的運作圖示說明。In addition, although only the left
透過保持器137讓左側導引輪組133的輪面1331沿著導引路徑1133移動,在移動過程中,熱風供應器131的加熱器1313持續加熱,以使熱風管1311內維持在工作溫度,並透過熱風槍將熱風管1311內的熱氣從氣孔13113吹向已被預熱的玻璃片300,而使已被預熱的玻璃片300暫時地貼合在起伏表面1119上,因此,隨著,成型裝置130從模具本體的前側邊移動到後側邊已被預熱的玻璃片300即可順應起伏表面1119來完成塑型,如圖8所示。The
此外,成型裝置移動的過程中熱氣從氣孔13113吹出方向與已被預熱的玻璃片300是保持在垂直狀態,這種吹氣方式能確保已被預熱的玻璃片300是確實順應起伏表面1119的變化。又,因為整個塑型過程都不需要接觸已被預熱的玻璃片300,因此,已被預熱的玻璃片300或最後成型的玻璃表面較不會殘留壓痕、刮傷或其他殘留汙染等。In addition, during the movement of the molding device, the blowing direction of the hot air from the
綜合上述,本發明的曲面玻璃成型設備是一種非接觸的方式,且採用熱氣流來型塑被加工玻璃,而不需要接觸被加工玻璃,以免汙染或損壞被加工玻璃。又,塑型過程中,供氣平面與起伏表面是維持在大致固定的間隔,而使熱氣流的推力維持大致相同。再者,透過熱氣流可維持被加工玻璃在可塑型的狀態中,因此,塑型完成後可透過其他降溫方式以讓玻璃有效率地定型。In summary, the curved glass forming equipment of the present invention is a non-contact method, and uses hot air to mold the processed glass without contacting the processed glass to avoid contamination or damage to the processed glass. In addition, during the molding process, the air supply plane and the undulating surface are maintained at a substantially constant interval, so that the thrust of the hot air flow is maintained substantially the same. Furthermore, through the hot air flow, the processed glass can be maintained in a moldable state. Therefore, after the molding is completed, other cooling methods can be used to efficiently set the glass.
最後,再次強調,本發明於前揭實施例中所揭露的構成元件,僅為舉例說明,並非用來限制本案之範圍,其他等效元件的替代或變化,亦應為本案之申請專利範圍所涵蓋。Finally, it is emphasized again that the constituent elements disclosed in the previously disclosed embodiments of the present invention are only examples and are not used to limit the scope of the case.
