Description

Curved glass forming equipment

This creation is related to glass forming equipment, especially a non-contact glass forming equipment.

Current curved glass forming equipment includes heaters, molds and forming rollers. At present, the forming method of curved glass is to put the processed glass on the mold first. At this time, the processed glass is flat. Next, the mold and the glass to be processed are heated so that the glass to be processed is softened and the external shape can be molded. Then, directly contact and press the surface of the processed glass through the forming roller, so that the processed glass conforms to the surface fluctuation of the mold to form a corresponding curved surface.

At present, this molding method needs to directly contact and roll the surface of the processed glass by the forming roller, so that the processed glass temporarily fits the surface of the mold, but because it needs direct contact, it is easy to process the glass during the molding process There are indentations, dirt or other pollution on the surface of the surface, which affects the quality of the curved glass.

Another method is to place the processed glass on the mold, and then soften the processed glass by heating to naturally conform to the shape of the mold. Although this method does not require contact, it is difficult to control the degree of bending of the processed glass. Therefore, this kind of The yield of the molding method is poor, and it is not conducive to mass production.

In view of the above deficiencies, the curved glass forming equipment of the present invention uses hot air flow to make the processed glass fit the undulating surface of the mold, so as to avoid leaving dirt, indentation or other pollution on the surface of the processed glass.

The curved glass forming equipment of this creation includes molds and forming devices. The mold includes a front side, a rear side, a left side, a right side, an undulating surface, and two guide paths. The undulating surface extends from the front side to the rear side, and is used to carry the pre-heated glass sheet. The two guide paths are located on the left and right sides, respectively. The forming device can move along the two guide paths, and the air supply plane faces the undulating surface, and keeps a distance from the pre-heated glass sheet. The air supply plane of the forming device can provide a positive pressure hot air flow to the pre-heated glass sheet, so that the pre-heated glass sheet temporarily adheres to the undulating surface.

Wherein, the molding device can move along the two guide paths including the movement of the molding device relative to the mold or the movement of the mold relative to the molding device.

In this way, the curved glass forming equipment of the present invention can make the preheated glass sheet temporarily adhere to the undulating surface through the hot air flow to avoid various problems caused by contact.

The composition, characteristics or operation of the curved glass forming equipment provided by this creation will be described in the detailed description of the subsequent implementation.

As shown in FIG. 3, the plurality of air holes 13113 may also be arranged in an array. As shown in FIG. 4, there are three straight lines formed by the air holes 13113. The air holes 13113 arranged at intervals can prevent the air flow from generating local large stress of line contact on the surface of the processed glass as in the conventional roller operation.

Referring again to FIG. 2, the left guide wheel group 133 and the right guide wheel group 135 are respectively connected to the hot air duct 1311, and part of the wheel surfaces 1331 and 1351 of the left guide wheel group 133 and the right guide wheel group 135 are slightly convex. The air supply plane 13111 of the hot air pipe 1311 is extended. The wheel surfaces 1331 and 1351 of the left guide wheel group 133 and the right guide wheel group 135 move along the guide path 1133 to keep the air supply plane 13111 and the undulating surface 1119 at a distance.

Referring again to FIG. 1, the holder 137 is connected to the hot air supply 131 so that the wheel surfaces 1331 and 1351 of the left guide wheel group 133 and the right guide wheel group 135 keep in contact with the top surfaces 1131 of the two guide plates 113, In this way, the interval between the air supply plane 13111 and the undulating surface 1119 can be maintained substantially uniform, and the air pressure blown by the hot air can also be relatively uniform.

In this embodiment, the holder 137 includes two rotating cylinders 1371 and two cantilevers 1373. The two cantilever arms 1373 are connected to the two rotating cylinders 1371 and the hot air pipe 1311 respectively. The rotating cylinder 1371 is used to drive the cantilever arm 1373 so that the wheel surfaces 1331 and 1351 of the left guide wheel group 133 and the right guide wheel group 135 can keep in contact with the two guides The top surface 1131 of the plate 113.

In another embodiment, as shown in FIG. 5, the holder 137a includes a telescopic cylinder 1371a and a fixing frame 1373a. The telescopic cylinder 1371a is connected to the fixing frame 1373a. The fixing frame 1373a is connected to the hot air pipe 1311a, and the telescopic cylinder 1371a is used to drive the fixing frame 1373a, so that the wheel surfaces of the left guide wheel group 133a and the right guide wheel group 135a can keep in contact with the two guide paths 1133a (as shown by the broken line in the figure) .

In this embodiment, the mold 110a has only the body 111a, and the guide plate is omitted. In other words, the guide path 1133a can be planned on the body 111a.

Although the above description is made with two types of retainers 137 and 137a, in other embodiments, the retainer may also use other methods or devices to make the wheel surface 1331 of the left guide wheel group 133 and the right guide wheel group 135 1351 remains in contact with the top surfaces 1131 of the two guide plates 113.

The composition and structure of the curved glass forming equipment of this creation are as described above, and then its operation and efficacy will be described.

As shown in Figure 6-8, the curved glass forming method is to preheat the processed glass to a moldable state, and then call the glass in this state the pre-heated glass sheet 300, the pre-heated glass sheet 300 is placed on the mold, that is, on the undulating surface 1119. Among them, the processed glass can be placed on the mold for preheating, or it can be preheated before being placed on the mold. In addition, before molding, the preheated glass sheet 300 placed on the undulating surface 1119 does not fit the undulating surface 1119, especially on the curved surface.

In addition, although only the left guide wheel group 133 is shown in FIGS. 6-8, it can be seen from the foregoing description that the structure, function, and operation of the right guide wheel group 135 are the same as the left guide wheel group 133, so the right side is omitted A graphical illustration of the operation of the guide wheel set 135.

Through the retainer 137, the wheel surface 1331 of the left guide wheel group 133 is moved along the guide path 1133. During the movement, the heater 1313 of the hot air supplier 131 continues to heat to maintain the working temperature in the hot air pipe 1311, And through the hot air gun, the hot air in the hot air pipe 1311 is blown from the air hole 13113 to the pre-heated glass sheet 300, so that the pre-heated glass sheet 300 is temporarily attached to the undulating surface 1119. Therefore, with, The molding device 130 moves from the front side of the mold body to the pre-heated glass sheet 300 to conform to the undulating surface 1119 to complete the molding, as shown in FIG. 8.

In addition, the hot air blowing direction from the air holes 13113 and the preheated glass sheet 300 are maintained in a vertical state during the movement of the molding device. This blowing method can ensure that the preheated glass sheet 300 conforms to the undulating surface 1119 The change. In addition, because the whole molding process does not need to contact the pre-heated glass sheet 300, the pre-heated glass sheet 300 or the final molded glass surface is less likely to leave indentation, scratches or other residual pollution. .

In summary, the curved glass forming equipment of the present invention is a non-contact method, and uses hot air flow to mold the processed glass without contacting the processed glass, so as not to contaminate or damage the processed glass. In addition, during the molding process, the air supply plane and the undulating surface are maintained at a substantially fixed interval, and the thrust of the hot air flow is maintained approximately 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 allow the glass to be shaped efficiently.
