[0040] At present, the cutting of 3D glass products usually adopts traditional laser cutting, automatic cutting machine, water jet cutting, flame cutting and the like. The traditional cutting method is prone to problems such as glass edge collapse, surface secondary scratch and uneven cutting edge during cutting, and the product shape is relatively rough and the size tolerance range is relatively large. Therefore, secondary CNC fine carving is usually required to obtain 3D glass products with high size precision. However, the cost of CNC fine carving is high, the process cycle is long, and the production capacity is low. In view of this, the present application provides a cutting device for 3D glass, which can obtain high cutting precision, and the cutting cost is low and the production efficiency is high.

[0041] Please refer to Figure 1 , Figure 2 and Figure 8The embodiment of the present application provides a cutting device 10 of 3D glass 100. The cutting device 10 comprises a profiling base 11, a profiling core 12, a movable cutter 13, a pressing plate 14 and a guide pin 15. The profiling base 11 is provided with a profiling groove 111 for placing the 3D glass 100 to be cut; the bottom of the profiling core 12 is matched with the profiling groove 111, and the profiling core 12 is provided with the guide pin 15; the guide pin 15 is arranged in the movable cutter 13, and the movable cutter 13 can slide horizontally along the guide pin 15, and the movable cutter 13 is provided with a blade 131 (see Figure 5 ). The cutting device 10 of the 3D glass 100 is used for cutting the 3D glass 100, and the cutting device 10 comprises the profiling base 11, the profiling core 12, the movable cutter 13, the pressing plate 14 and the guide pin 15. The profiling base 11 is provided with the profiling groove 111 for placing the 3D glass 100 to be cut; the bottom of the profiling core 12 is matched with the profiling groove 111, and the profiling core 12 is provided with the guide pin 15; the guide pin 15 is arranged in the movable cutter 13, and the movable cutter 13 can slide horizontally along the guide pin 15, and the movable cutter 13 is provided with the blade 131; the pressing plate 14 is used for driving the movable cutter 13 to slide horizontally along the guide pin 15, and the blade 131 is used for cutting the 3D glass 100.

[0042] The cutting device 10 of the 3D glass 100 is used for cutting the 3D glass 100, and the cutting device 10 comprises the profiling base 11, the profiling core 12, the movable cutter 13, the pressing plate 14 and the guide pin 15. The profiling base 11 is provided with the profiling groove 111 for placing the 3D glass 100 to be cut; the bottom of the profiling core 12 is matched with the profiling groove 111, and the profiling core 12 is provided with the guide pin 15; the guide pin 15 is arranged in the movable cutter 13, and the movable cutter 13 can slide horizontally along the guide pin 15, and the movable cutter 13 is provided with the blade 131; the pressing plate 14 is used for driving the movable cutter 13 to slide horizontally along the guide pin 15, and the blade 131 is used for cutting the 3D glass 100.

[0043] In a high-temperature environment, the glass is in a softened state, and if there is no profiling device, the appearance of the 3D glass 100 is easy to deform and the position of the 3D glass 100 is easy to move during cutting. The matching profiling groove 111 and the profiling core 12 are arranged to fix the 3D glass 100, so that the influence of external factors is reduced, and the deformation and position movement of the 3D glass 100 are avoided. When the cutting movement is performed, the profiling core 12 is pressed downward by the pressing plate 14 and is matched with, pressed and fixed to the 3D glass 100. The 3D glass 100 subjected to the pressure is prevented from moving in position. The process of secondary pressing and molding can repair and adjust the adverse factors caused by the one-time molding of the 3D glass 100, so that the profiling effect and the shaping effect are achieved, the size error is reduced, the cutting precision of the 3D glass 100 is improved, the defective product rate is reduced, and the yield of the 3D glass 100 is improved.

[0044] The cutting device 10 has a good appearance of the cut and formed product, no secondary damage, and a smooth and flat cutting surface without obvious undesirable features, and can achieve the requirements of appearance and precision. Compared with secondary CNC fine carving, the cutting device 10 has a simple structure, low cutting production cost, and high production efficiency, and can reduce the cutting production cost of the 3D glass 100 and improve the cutting production efficiency of the 3D glass 100.

[0045] The cutting device 10 can replace the secondary CNC fine carving equipment to perform secondary processing on the 3D glass 100 cut by the traditional cutting device, thereby reducing the process cost of secondary processing. At the same time, the cutting device 10 can also replace the traditional cutting device to directly perform primary processing on the 3D glass 100, thereby effectively reducing the secondary damage to the glass. Moreover, the cutting device 10 can be repeatedly used.

[0046] In some embodiments, the profiling base 11, the 3D glass 100, and the profiling core 12 can be combined and then heated as a whole in a heater. The heater can be a separate heating device that is independent of the cutting device 10. Specifically, the heater can be an existing heating device such as a resistance heating furnace.

[0047] In some embodiments, the cutting device 10 further includes a heating unit that can be used to heat the 3D glass 100 to be cut to soften the 3D glass. It should be noted that the heating unit is not shown in the drawings of the present application. By providing the heating unit in the cutting device 10 itself, it is not necessary to use an additional heating device to heat the 3D glass 100. Specifically, the heating unit can be an existing heating device such as a resistance heating furnace.

[0048] In some embodiments, the profiling base 11 and the profiling core 12 are made of a material that has good heat resistance and heat conduction performance. In this way, the 3D glass 100 can be better heated to soften. It should be understood that the profiling base 11 and the profiling core 12 can be made of a material that is commonly used in the art, such as some commonly used metal or alloy materials, which has good heat resistance and heat conduction performance.

[0049] Please refer to Figure 1 , Figure 2 and Figure 6In some embodiments, the active cutter 13 has a slope 132 on the side close to the profiled core 12, and the slope 132 is inclined upward along the direction from one end to the other end of the active cutter 13 close to the profiled core 12; and the wedge-shaped pressing block 141 is arranged on the lower side of the pressing plate 14 and matches the slope 132. In this way, when the pressing plate 14 is pressed down, the wedge-shaped pressing block 141 cooperates with the slope 132 of the active cutter 13 to make the active cutter 13 slide horizontally outward along the guide pin 15, so as to cut the 3D glass 100. In this way, the active cutter 13 can be more conveniently driven to slide along the guide pin 15 by the pressing plate 14, so as to more conveniently cut the 3D glass 100.

[0050] In some embodiments, the blade edge 131 is arranged on the bottom side of the active cutter 13 away from the profiled core 12. In this way, when the 3D glass 100 is cut, the pressing plate 14 is pressed down, the active cutter 13 slides horizontally outward along the guide pin 15 through the cooperation of the wedge-shaped pressing block 141 and the slope 132, and then the 3D glass 100 is cut through the blade edge 131 arranged on the bottom side of the active cutter 13 away from the profiled core 12.

[0051] Please refer to Figure 3 and Figure 7 In some embodiments, the positioning groove 112 is arranged on the profiled base 11, and the positioning block 142 matching the positioning groove 112 is arranged on the lower side of the pressing plate 14. Through the cooperation of the positioning groove 112 and the positioning block 142, the positioning block 142 is inserted into the positioning groove 112 during the process of driving the active cutter 13 to slide and cut the 3D glass by pressing down the pressing plate 14, so as to position the pressing plate 14 and avoid horizontal displacement during the pressing process, thereby improving the working stability of the cutting device 10 and the cutting precision of the 3D glass 100.

[0052] In some embodiments, the width of the positioning groove 112 gradually decreases from the opening end of the positioning groove 112 to the bottom of the positioning groove 112, and the width of the positioning block 142 also gradually decreases from the root of the positioning block 142 to the free end of the positioning block 142. In this way, when the pressing plate 14 is pressed down to drive the active cutter 13 to slide, the free end of the positioning block 142 can be more conveniently inserted into the positioning groove 112, without the need for very precise alignment of the positioning groove 112 and the positioning block 142.

[0053] It should be noted that the difference between the width of the opening end of the positioning groove 112 and the width of the bottom of the positioning groove 112 should not be too large; similarly, the difference between the width of the root of the positioning block 142 and the width of the free end of the positioning block 142 should not be too large. If the width difference is too large, the pressing plate 14 may be horizontally displaced by a certain amplitude during the pressing process, which may affect the working stability and cutting accuracy of the cutting device 10. It can be understood that the difference between the width of the opening end of the positioning groove 112 and the width of the bottom of the positioning groove 112, and the difference between the width of the root of the positioning block 142 and the width of the free end of the positioning block 142, can be set according to actual production conditions, and are not specifically limited in the present application.

[0054] In some embodiments, a plurality of positioning grooves 112 are provided on the profiling base 11, and the plurality of positioning grooves 112 are arranged symmetrically along the center line of the profiling base 11. A plurality of positioning blocks 142 are provided on the lower side of the pressing plate 14, and the plurality of positioning blocks 142 are arranged symmetrically along the center line of the pressing plate 14, and the position of each positioning block 142 corresponds to the position of the corresponding positioning groove 112. In this way, through the cooperation of the plurality of symmetrically arranged positioning grooves 112 and positioning blocks 142, the working stability of the cutting device 10 can be further improved, and the cutting accuracy of the 3D glass 100 can be further improved.

[0055] Referring to Figure 4 and Figure 6 In some embodiments, the profiling core 12 has a tool sliding platform 121, and the movable cutter 13 is slidably arranged on the tool sliding platform 121. It can be understood that the tool sliding platform 121 is a portion extending outward from the main body of the profiling core 12. By providing the tool sliding platform 121 on the profiling core 12 and slidably arranging the movable cutter 13 on the tool sliding platform 121, when the pressing plate 14 is pressed to drive the movable cutter 13 to slide horizontally along the guide pin 15, the movable cutter 13 slides on the tool sliding platform 121, which can further improve the stability of the sliding of the movable cutter 13, improve the stability of the cutting of the 3D glass 100 by the cutting edge 131, and thus improve the cutting accuracy of the 3D glass 100.

[0056] Referring to Figure 1 It can be understood that before cutting the 3D glass 100, the movable cutter 13 is placed on the tool sliding platform 121, and the cutting edge 131 at the bottom of the movable cutter 13 is located inside the skirt portion to be cut of the 3D glass 100. Referring to Figure 2 After the pressing plate 14 is pressed to drive the movable cutter 13 to slide horizontally along the guide pin 15, the movable cutter 13 moves outward on the tool sliding platform 121, and the cutting edge 131 at the bottom of the movable cutter 13 moves outward to cut the skirt portion of the 3D glass 100. The tool sliding platform 121 on the profiling core 12 provides a stable bearing platform for the sliding of the movable cutter 13.

[0057] Referring toFigure 3 In some embodiments, a platform 113 is provided on the profiling base 11 near the profiling groove 111, and the height of the platform 113 is consistent with the height of the upper edge of the side wall of the profiling groove 111. By providing the platform 113 on the profiling base 11 near the profiling groove 111, the discarded glass skirt portion after cutting can be accommodated, and the end of the movable cutter 13 provided with the cutting edge 131 can be carried to the outside.

[0058] It can be understood that the height of the platform 113 should not be higher than the height of the upper surface of the cutter sliding table 121 when cutting the 3D glass 100. In other words, the height of the platform 113 can be consistent with or slightly lower than the height of the upper surface of the cutter sliding table 121. In this way, the end of the movable cutter 13 provided with the cutting edge 131 can smoothly cut the 3D glass 100 and smoothly slide onto the platform 113.

[0059] Please refer to Figure 5 In some embodiments, a cutting groove 133 is provided on the lower part of the movable cutter 13 away from the profiling core 12, and a movable cutter carrying table 114 is provided on the profiling base 11 away from the profiling groove 111. By providing the cutting groove 133 and the movable cutter carrying table 114 to cooperate with each other, the movable cutter carrying table 114 can carry the movable cutter 13 after the movable cutter 13 moves outward to cut the 3D glass 100; the gap between the side wall of the cutting groove 133 on the platform 113 and the side wall of the movable cutter carrying table 114 can provide storage space for the discarded glass skirt after cutting. Moreover, the side wall of the profiling base 11 away from the cutting edge 131 of the movable cutter 13 can limit the outward movement distance of the movable cutter 13.

[0060] It can be understood that the height of the movable cutter carrying table 114 can be slightly lower than the height of the top surface of the cutting groove 133, so as to ensure that the movable cutter carrying table 114 can carry the end of the movable cutter 13 provided with the cutting edge 131, without blocking the movement of the movable cutter 13.

[0061] In some embodiments, the width of the movable cutter carrying table 114 is smaller than the width of the cutting groove 133. By providing the movable cutter carrying table 114, the movable cutter 13 can be limited by the side wall of the profiling base 11 on one side of the movable cutter carrying table 114, so as to ensure that there is still a gap between the movable cutter carrying table 114 and the cutting edge 131 when the movable cutter 13 moves to the outermost position, which can serve as a storage space for the discarded glass skirt after cutting, and can also avoid the cutting edge 131 from being damaged by contacting the movable cutter carrying table 114.

[0062] In some embodiments, a plurality of guide pins 15 are arranged in the movable cutter 13. In this way, the sliding freedom of the movable cutter 13 can be better limited, so that the movable cutter 13 can only slide horizontally along the guide pins 15, further improving the stability of the movable cutter 13 sliding horizontally along the guide pins 15, and further improving the cutting accuracy of the 3D glass 100.

[0063] In some embodiments, the movable cutter 13 is provided with a connecting hole 134 for the insertion of the guide pin 15, one end of the guide pin 15 is inserted into the connecting hole 134, and the other end of the guide pin 15 is fixedly inserted into the profiling core 12.

[0064] It can be understood that the diameter of the connecting hole 134 should be slightly larger than the diameter of the guide pin 15, so that the movable cutter 13 can conveniently slide horizontally along the guide pin 15. At the same time, the diameter of the connecting hole 134 should not be too large, otherwise it will affect the stability of the movable cutter 13 when sliding, and further affect the cutting accuracy of the cutting device 10. The specific diameter of the connecting hole 134 can be set according to the actual situation, which is not specifically limited in the present application.

[0065] In addition, the connecting hole 134 can be a through hole or a blind hole; it is only required to ensure that the depth of the connecting hole 134 can make the blade edge 131 located inside the skirt to be cut of the 3D glass 100 when the movable cutter 13 is closest to the profiling core 12. In a specific example, the connecting hole 134 is a through hole.

[0066] In some embodiments, the profiling core 12 is provided with guide pins 15 on both sides or around the circumference, and the movable cutter 13 is arranged on the guide pins 15 on both sides or around the circumference of the profiling core 12. That is, the movable cutter 13 described above can be arranged on both sides of the left and right sides of the profiling core 12, or on the front and back sides. When the movable cutter 13 is arranged around the circumference, a plurality of movable cutters 13 surround the profiling core 12. In this way, the cutting device 10 can be suitable for 3D glass products whose skirt parts on both sides or around the circumference need to be cut, such as groove structure 3D glass products with both ends open or 3D mobile phone cover plates. By moving the movable cutters 13 on the front and back sides outward, the skirt around the circumference of the 3D glass 100 can be cut off.

[0067] It can be understood that the cutting device 10 as shown in Figure 8 can be suitable for cutting the skirt of a groove structure 3D glass product with both ends open (the structure of which is shown in Figure 9 ), that is, the skirt parts on both sides of the 3D glass product can be cut off. If the skirt around the circumference of the 3D glass product needs to be cut off, the corresponding movable cutters 13 need to be added to the front and back ends of the profiling core 12 of the cutting device 10 as shown in Figure 8 .

[0068] An embodiment of the present application provides a cutting method of the 3D glass 100, which cuts the 3D glass 100 by using the cutting device 10 of the present application. The cutting method comprises the following steps:

[0069] Step S100: placing the 3D glass 100 to be cut in the profiling groove 111 of the profiling base 11;

[0070] Step S200: placing the profiling core 12 on the 3D glass 100;

[0071] Step S300: placing the profiling base 11, the 3D glass 100 and the profiling core 12 together in the heater to heat and soften the 3D glass;

[0072] Step S400: pressing the pressing plate 14 to make the movable cutter 13 connected to the profiling core 12 slide horizontally along the guide pin 15, and cutting the skirt part of the 3D glass 100 by the blade 131 at the bottom of the movable cutter 13 during the sliding of the movable cutter 13.
