Description

Technical Field

[0001] The utility model relates to the field of 3D glass thermal bending, in particular to a 3D glass thermal bending protection device. Background Art

[0002] 3D glass is widely used in smartphones and smart wearable devices. After being heated, softened and bent, 3D glass can be processed into curved glass, which has better adhesion to some curved screen devices.

[0003] Existing 3D glass hot bending devices, such as the hot bending device for glass processing proposed in patent application number "CN202122553033.7", can effectively prevent the glass from lacking corresponding fixings during the hot bending process, causing its position to shift and shake, affecting the hot bending effect, through structures such as the base, the hot bending part, and the adaptive fixing component. It can also prevent traditional fixed fixings from being difficult to adaptively deform according to the bending conditions of the glass during the glass bending process, resulting in the bending of the middle part of the glass, which will cause the clamped and fixed parts on both sides to break, thereby effectively protecting the glass.

[0004] However, when the 3D glass is hot-bent, the fixing components fix the two ends of the glass, which will cause indentations on the two ends of the glass. In the prior art, glass protective oil is coated on the glass before hot-bending. If the glass protective oil is not applied evenly, the glass surface will be uneven and the product yield will be low. In severe cases, the bent part of the glass will break or the hot bending effect will be poor when the glass is hot-bent. Therefore, a 3D glass hot bending protection device is proposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A rotating column 4 is rotatably connected between the base 1 and the top plate 2, and a support plate 11 is rotatably connected to the side wall of the rotating column 4. The rotating column 4 and the support plate 11 enable the support plate 11 to be flipped and moved. A cylinder 16 (model TN10-30) is fixedly connected to the upper end of the support plate 11, and a vacuum suction cup 17 for vacuum adsorption of 3D glass 20 is fixedly connected to the output end of the cylinder 16. A scraper 24 for scraping the 3D glass 20 is fixedly connected to the lower end of the oil outlet plate 23. An oil outlet hole 25 is opened at a position on one side of the scraper 24 at the lower end of the oil outlet plate 23, and a hot bending component is fixedly connected to one side of the upper end of the support plate 11.

[0026] like Figure 1-Figure 4As shown, the cylinder 16 and the vacuum suction cup 17 absorb and fix the 3D glass 20 to avoid indentations caused by clamping, and protect the two ends of the 3D glass 20. The electric push rod 22 (model DYTP450- / 110) drives the oil outlet plate 23 to approach the 3D glass 20, and the oil outlet hole 25 applies glass protection oil to the surface of the 3D glass 20. The electric push rod 22 is controlled to move so that the scraper 24 at the lower end of the oil outlet plate 23 scrapes the glass protection oil, and the glass protection oil is evenly and flatly applied to the glass surface to avoid unevenness of the glass surface after oil coating, thereby improving the product yield and protecting the glass from hot bending to a certain extent. After the glass oil is coated and solidified, the support plate 11 is controlled to flip and the rotating column 4 is rotated so that the hot bending component faces downward for the hot bending process.

[0027] The support plate 11 is set to be arc-shaped, the slide rail is located above the cylinder 16, the hot bending assembly and the cylinder 16 are arranged in a circular array relative to the rotating column 4, and a fixture assembly is fixed to the upper end of the base 1, and the fixture assembly cooperates with the hot bending assembly for hot bending.

[0028] like Figure 1-Figure 2 As shown, the arc-shaped support plate 11 is convenient for rotation and flipping, and the moving path of the slide rail driving the slider 21 is parallel to the long side of the 3D glass 20. When the support plate 11 is flipped, the cylinder 2 16 gently places the 3D glass 20 on the jig assembly, drives the rotating column 4 to rotate, and rotates the hot bending assembly to the upper end of the jig assembly. At this time, the hot bending assembly can cooperate with the jig assembly for hot bending.

[0029] The support plate 11 has a collecting groove 14 for collecting protective oil at its upper end, the cylinder 2 16 is located in the middle of the collecting groove 14, a collecting hole 15 is provided at the bottom of the collecting groove 14, a collecting pipe is provided inside the support plate 11, and the collecting hole 15 is connected to the collecting pipe.

[0030] like Figure 1-Figure 2 As shown, when the scraper 24 scrapes the glass oil flat, the excess glass oil will fall into the collecting tank 14 and enter the collecting pipe through the collecting hole 15, preventing the excess glass oil from contaminating the support plate 11 and affecting the hot bending process.

[0031] The upper end of the top plate 2 is fixedly connected to an oil tank 8 and an oil pump 9, a connecting pipe 2 19 is connected and fixedly connected between the oil tank 8 and the oil outlet plate 23, a connecting pipe 18 is connected and fixedly connected between the oil pump 9 and the side wall of the support plate 11, and one end of the connecting pipe 18 is connected to the collection pipe.

[0032] like Figure 1 As shown, an oil pump is provided at one end of the connecting pipe 2 19 located in the oil tank 8, which is used to extract the glass protection oil in the oil tank 8 and transport it to the oil outlet plate 23 through the connecting pipe 2 19. The oil pump 9 extracts the glass protection oil in the pipeline through the connecting pipe 18 to prevent the glass protection oil in the collecting tank 14 from affecting the hot bending process.

[0033] The hot bending assembly includes a cylinder 12 , which is fixed to the upper end of a support plate 11 , a pressure plate 13 is fixed to the output end of the cylinder 12 , and the cylinder 12 is located on one side of the cylinder 2 16 .

[0034] like Figure 1-Figure 2 As shown, the cylinder 12 drives the pressing plate 13. When the 3D glass 20 is located on the 3D fixture 7, both ends of the 3D glass 20 are heated and softened, so that the pressing plate 13 rolls the 3D glass 20 into shape, and the two ends of the 3D glass 20 are bent to form a curved surface.

[0035] The jig assembly includes a processing table 6 , which is located at the upper end of the base 1 , a 3D jig 7 is fixedly connected to the upper end of the processing table 6 , and a pressing plate 13 is matched with the 3D jig 7 by hot bending.

[0036] like Figure 1 , Figure 4 As shown, the shape of the 3D jig 7 can be customized according to the product, and the pressing plate 13 and the 3D jig 7 together press the 3D glass 20 into shape.

[0037] The working principle of a 3D glass thermal bending protection device provided by the utility model is as follows:

[0038] The 3D glass 20 is fixed by the cylinder 16 and the vacuum suction cup 17 to avoid indentations caused by clamping and to protect both ends of the 3D glass 20. The electric push rod 22 drives the oil outlet plate 23 to approach the 3D glass 20. The oil outlet hole 25 applies glass protection oil to the surface of the 3D glass 20. The electric push rod 22 is controlled to move so that the scraper 24 at the lower end of the oil outlet plate 23 scrapes the glass protection oil, and the glass protection oil is evenly and evenly applied to the glass surface to avoid unevenness of the glass surface after oil coating, thereby improving the product yield and protecting the glass from hot bending to a certain extent.
