[0001] The invention relates to the technical field of glass substrate production, and in particular to a muffle furnace glass guiding device with a quality inspection function. Background Art

[0002] The overflow down-draw method is an advanced glass manufacturing technology, which is mainly used to produce high-quality and high-precision flat glass. After the glass substrate is formed in the furnace, it needs to be sent out of the furnace through a traction device to complete the forming process of the glass substrate.

[0003] In the process of the glass substrate leaving the furnace, the roller gap of the traction device may change, which may lead to inconsistency between the thickness of the glass substrate and the roller gap, causing the glass substrate to break in the process of leaving the furnace. Since the inside of the furnace is dim, it is not possible to detect whether the glass substrate is broken or whether the roller gap has changed in the first time, so further improvements are needed on this basis. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 2 As shown, this embodiment provides a muffle furnace glass guiding device with quality inspection function, including:

[0023] A base 1, the base 1 is connected to the muffle furnace;

[0024] A guide assembly is mounted on the base 1. When the muffle furnace formed glass guided by the guide assembly cracks, the first guide roller 7 in the guide assembly at the first preset position against the glass is driven to move in a direction away from the glass;

[0025] A position monitoring component, which is mounted on the base 1 and is used to monitor the real-time position of the first guide roller 7;

[0026] The controller is mounted on the base 1. When the position monitoring component detects that the distance difference between the first guide roller 7 and the first position exceeds a preset value, it is determined that the glass is cracked.

[0027] On the whole, when the glass reaches the outlet of the muffle furnace after completing the molding process through the overflow down-draw method, the guiding speed of the guide assembly is kept consistent with the falling speed of the glass. When the glass is smoothly guided out of the muffle furnace through the guide assembly, the position monitoring assembly monitors the position of the first guide roller 7 in real time. When the position monitoring assembly detects that the distance difference between the displacement of the first guide roller 7 and the first position does not exceed the preset value, it is determined that the glass is not cracked. In the process of the glass being guided out of the muffle furnace through the guide assembly, the position monitoring assembly monitors the position of the first guide roller 7 in real time. When the position monitoring assembly detects that the distance difference between the displacement of the first guide roller 7 and the first position exceeds the preset value, it is determined that the glass is cracked.

[0028] like Figure 1-Figure 2 As shown, in this embodiment, the guide assembly includes a first guide roller group and a second guide roller group. The first guide roller group is movably mounted on the first guide rail 101 of the base 1, and the second guide roller group is fixedly mounted on the base 1.

[0029] Specifically, the guide assembly includes a first guide roller group and a second guide roller group. When the glass reaches the outlet of the muffle furnace after completing the forming process through the overflow down-draw method, the linear speed of the first guide roller group and the second guide roller group is consistent with the falling speed of the glass, and the first guide roller group and the second guide roller group have opposite directions, which can ensure that the glass can fall and discharge stably. In the process of the glass being guided out of the muffle furnace through the first guide roller group and the second guide roller group, the position monitoring assembly monitors the position of the first guide roller 7 in real time. When the position monitoring assembly detects that the distance difference between the displacement of the first guide roller 7 and the first position does not exceed the preset value, it is determined that the glass is not cracked. In the process of the glass being guided out of the muffle furnace through the guide assembly, the position monitoring assembly monitors the position of the first guide roller 7 in real time. When the position monitoring assembly detects that the distance difference between the displacement of the first guide roller 7 and the first position exceeds the preset value, it is determined that the glass is cracked.

[0030] like Figure 1 As shown, in this embodiment, a reset member 10 is also included. The reset member 10 is connected to the base 1 and the first guide roller group respectively. The reset member 10 is used to reset the displaced first guide roller 7 to the first position and continue to abut against the glass.

[0031] Specifically, it also includes a reset member 10. When the glass is guided out of the muffle furnace along the first guide roller group and the second guide roller group, the falling speed of the glass cannot be consistent with the linear speed of the first guide roller group and the second guide roller group due to the influence of the external environment. Therefore, the glass will come into contact with the first guide roller group and the second guide roller group, and then the first guide roller 7 will move along the path of the first guide rail 101. By setting the reset member 10, the first guide roller group can be reset in time along the first guide rail 101, so that the glass can be more stable during the guiding process to prevent the glass from cracking.

[0032] like Figure 1-Figure 2 As shown, in the present embodiment, the first guide roller group includes a first plate body 2, a second plate body 3, a first motor 4, a first guide roller 7 and a screw 6. The first plate body 2 is movably mounted on the first guide rail 101 of the base 1. The second plate body 3 is movably mounted on the second guide rail 201 of the first plate body 2. The extension direction of the second guide rail 201 is consistent with the extension direction of the first guide rail 101. The first motor 4 is mounted on the second plate body 3. The first motor 4 is connected to the first guide roller 7. The first motor 4 can drive the first guide roller 7 to rotate. The screw 6 is adapted to pass through the screw hole opened on the second plate body 3. The axial direction of the screw 6 is consistent with the extension direction of the second guide rail 201. The screw 6 can rotate relative to the first plate body 2.

[0033] Specifically, after the glass is formed by the overflow down-draw method, it is led out of the muffle furnace through the first guide roller group and the second guide roller group. When the first guide roller group and the second guide roller group are in contact with both sides of the glass for a long time, the first guide roller 7 will undergo a certain amount of wear, resulting in an increase in the gap between the first guide roller group and the second guide roller group, which in turn causes the glass to shake more at the positions of the first guide roller group and the second guide roller group, ultimately causing the glass to crack. In order to make the glass more stable during the export process, by rotating the screw 6, since the screw 6 is adapted to the screw hole on the second plate 3, the second plate 3 can be moved along the second guide rail 201 to achieve adjustment of the distance between the first guide roller group and the second guide roller group, thereby improving the stability of the glass during the guiding process.

[0034] like Figure 1 As shown, in this embodiment, the second guide roller group includes a second motor 5 and a second guide roller 8. The second motor 5 is installed on the base 1. The second motor 5 is connected to the second guide roller 8. The second motor 5 can drive the second guide roller 8 to rotate. The second guide roller 8 is axially parallel to the first guide roller 7.

[0035] Specifically, the second guide roller group includes a second motor 5. After the glass is formed by the overflow down-draw method, it is led out of the muffle furnace through the first guide roller group and the second guide roller group. When the first guide roller group and the second guide roller group are in contact with both sides of the glass for a long time, the second guide roller 8 will also undergo a certain amount of wear, resulting in an increase in the gap between the first guide roller 7 and the second guide roller 8, thereby causing the glass to shake at a larger amplitude at the position of the first guide roller 7 and the second guide roller 8, causing the glass to crack. In order to make the glass more stable during the export process, by rotating the screw 6, since the screw 6 is adapted to the screw hole on the second plate 3, the second plate 3 can be moved along the second guide rail 201 to achieve adjustment of the distance between the first guide roller 7 and the second guide roller 8, thereby improving the stability of the glass during the guiding process.

[0036] like Figure 1-2 As shown, in this embodiment, the position monitoring component is specifically an infrared emitter 9, and a first plane 91 where the infrared rays emitted by the infrared emitter 9 are located is coplanar with the mid-vertical plane on the axial direction where the first guide roller 7 is located.

[0037] Specifically, the position monitoring component is an infrared emitter 9. By making the first plane 91 where the infrared rays of the infrared emitter 9 are located coplanar with the mid-vertical plane on the axial direction of the first guide roller 7, the infrared emitter 9 can more accurately monitor the vibration amplitude of the first guide roller 7, thereby improving the monitoring accuracy of the infrared emitter 9.

[0038] Of course, it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
