Description

Technical Field

[0001] This invention relates to the field of glass substrate production technology, and in particular to a glass guiding device for a muffle furnace with quality inspection function. Background Technology

[0002] Overflow pull-down is an advanced glass manufacturing technology, mainly used to produce high-quality, high-precision flat glass. After the glass substrate has been formed in the furnace, it needs to be sent out of the furnace by a traction device to complete the forming process of the glass substrate.

[0003] During the process of the glass substrate exiting the furnace, the gap between the rollers of the traction device may change, which may lead to a mismatch between the thickness of the glass substrate and the roller gap, causing the glass substrate to break during the furnace process. Since the inside of the furnace is dark, it is not possible to detect whether the glass substrate has broken or whether the roller gap has changed in the first place. Therefore, further improvements are needed. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a glass guiding device for a muffle furnace with quality inspection function.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A glass guiding device for a muffle furnace with quality inspection function, located at the discharge end of the muffle furnace, characterized in that it comprises:

[0007] Base, the base is connected to the muffle furnace;

[0008] The guide assembly is mounted on the base. When the muffle furnace formed glass guided by the guide assembly cracks, it will drive the first guide roller in the guide assembly, which is in the first preset position against the glass, to move away from the glass.

[0009] A position monitoring component is mounted on the base and is used to monitor the real-time position of the first guide roller.

[0010] The controller is mounted on the base. When the position monitoring component detects that the distance difference between the first guide roller displacement and the first preset position exceeds a preset value, it determines that the glass has cracked.

[0011] Preferably, the guide assembly includes a first guide roller group and a second guide roller group. The first guide roller group is movably mounted on a first guide rail of the base, and the second guide roller group is fixedly mounted on the base.

[0012] Preferably, it further includes a reset member, which is connected to the base and the first guide roller group respectively. The reset member is used to reset the first guide roller that has been displaced to the first preset position and continue to abut against the glass.

[0013] Preferably, the first guide roller assembly includes a first plate, a second plate, a first motor, a first guide roller, and a screw. The first plate is movably mounted on a first guide rail of the base, and the second plate is movably mounted on a second guide rail of the first plate. The extension direction of the second guide rail is consistent with the extension direction of the first guide rail. The first motor is mounted on the second plate and connected to the first guide roller. The first motor can drive the first guide roller to rotate. The screw is adapted to pass through a screw hole opened on the second plate. The axial direction of the screw is consistent with the extension direction of the second guide rail, and the screw can rotate relative to the first plate.

[0014] Preferably, the second guide roller assembly includes a second motor and a second guide roller. The second motor is mounted on the base and connected to the second guide roller. The second motor can drive the second guide roller to rotate. The second guide roller is axially parallel to the first guide roller.

[0015] Preferably, the position monitoring component is an infrared emitter, and the first plane in which the infrared rays emitted by the infrared emitter are located is coplanar with the vertical plane in the axial direction of the first guide roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Compared with existing technologies, by setting up a guide component, the speed of the glass can be made more stable during the process of being discharged from the muffle furnace, avoiding cracking of the glass due to inconsistent speed during discharge. This can effectively improve the glass utilization rate. Furthermore, by setting up a position monitoring component, cracking of the glass can be detected in time, and the guide component can be adjusted accordingly based on the thickness of the glass in the muffle furnace to ensure the stability of the glass during the discharge process.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

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

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

[0024] The guide assembly is mounted on the base 1. When the muffle furnace formed glass guided by the guide assembly cracks, it will drive the first guide roller 7 in the guide assembly, which is in the first preset position against the glass, to move away from the glass.

[0025] A position monitoring component 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 installed on the base 1. When the position monitoring component detects that the distance difference between the first guide roller 7 and the first preset position exceeds a preset value, it determines that the glass has cracked.

[0027] Overall, after the glass is formed by the overflow pull-down method and reaches the outlet of the muffle furnace, the guiding speed of the guide assembly is kept consistent with the falling speed of the glass. During the process of the glass being smoothly discharged from the muffle furnace through the guide assembly, the position monitoring component monitors the position of the first guide roller 7 in real time. When the position monitoring component detects that the distance difference between the displacement of the first guide roller 7 and the first preset position does not exceed the preset value, it is determined that the glass has not cracked. However, during the process of the glass being discharged from the muffle furnace through the guide assembly, the position monitoring component monitors the position of the first guide roller 7 in real time. When the position monitoring component detects that the distance difference between the displacement of the first guide roller 7 and the first preset position exceeds the preset value, it is determined that the glass has cracked.

[0028] like Figures 1-2 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 guiding assembly includes a first guide roller group and a second guide roller group. After the glass is formed by the overflow pull-down method and reaches the outlet of the muffle furnace, the linear velocity 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 rotate in opposite directions to ensure that the glass can fall and be discharged stably. During the process of the glass being discharged from the muffle furnace through the first guide roller group and the second guide roller group, the position monitoring component monitors the position of the first guide roller 7 in real time. When the position monitoring component detects that the distance difference between the displacement of the first guide roller 7 and the first preset position does not exceed the preset value, it is determined that the glass has not cracked. During the process of the glass being discharged from the muffle furnace through the guiding assembly, the position monitoring component monitors the position of the first guide roller 7 in real time. When the position monitoring component detects that the distance difference between the displacement of the first guide roller 7 and the first preset position exceeds the preset value, it is determined that the glass has 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 first guide roller 7 that has been displaced to the first preset position and continue to abut against the glass.

[0031] Specifically, it also includes a reset component 10. When the glass is discharged from the muffle furnace along the first guide roller group and the second guide roller group, the falling speed of the glass cannot be kept in line with the linear speed of the first guide roller group and the second guide roller group due to the influence of the external environment. This will cause the glass to come into contact with the first guide roller group and the second guide roller group, which will cause the first guide roller 7 to move along the path of the first guide rail 101. By setting the reset component 10, the first guide roller group can be reset in time along the first guide rail 101, making the glass more stable during the guiding process and preventing the glass from cracking.

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

[0033] Specifically, after the glass is formed by the overflow pull-down method, it is discharged from the muffle furnace through the first guide roller group and the second guide roller group. However, due to the long-term contact between the first guide roller group and the two sides of the glass, the first guide roller 7 will experience some wear, resulting in an increase in the gap between the first guide roller group and the second guide roller group. This causes the glass to wobble significantly at the positions of the first guide roller group and the second guide roller group, ultimately leading to glass cracking. To make the glass more stable during the discharge process, the screw 6 is rotated. Since the screw 6 is adapted to the screw hole on the second plate 3, the second plate 3 can move along the second guide rail 201 to adjust the gap 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 mounted on the base 1 and 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 pull-down method, it is discharged from the muffle furnace through the first guide roller group and the second guide roller group. However, 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 experience some wear, which will increase the gap between the first guide roller 7 and the second guide roller 8. This will cause the glass to shake more at the position of the first guide roller 7 and the second guide roller 8, resulting in glass cracking. In order to make the glass more stable during the discharge process, the screw 6 is rotated. 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 adjust the gap 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. The first plane 91 where the infrared rays emitted by the infrared emitter 9 are located is coplanar with the vertical plane on the axial direction of the first guide roller 7.

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