Description

Technical Field

[0001] The present invention relates to the technical field of fused silica glass ingots, and particularly to a qualified detection device and method for large-size and few-bubble fused silica glass ingots. Background Art

[0002] Quartz glass has excellent physical and chemical properties, as well as the best ultraviolet spectrum transmission performance, visible light and near-infrared spectrum transmission performance, and is widely used in fields such as chemical industry, electronics, metallurgy, building materials, and national defense. It can be used to make semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment, and high-temperature and corrosion-resistant chemical instruments, etc. As the basic raw material for various quartz glass products, the quality of the melted finished product of the quartz glass ingot is very important. Especially for the quartz glass ingot prepared by the gas melting method, although the generation of bubbles can be reduced during the gas melting process, the quartz glass ingot cannot completely avoid the generation of defects such as bubbles, and defects such as bubbles will have a great impact on the stability and reliability of quartz glass products, seriously affecting the subsequent processing of quartz glass products. Therefore, the quartz glass ingot must be detected before leaving the factory.

[0003] The existing detection of defects such as bubbles in quartz glass ingots mainly adopts manual detection. For example, a light source is used to irradiate the quartz glass ingot, and the inspection personnel visually check it. This detection method extremely relies on the professional skills of the personnel, and for large-size quartz glass ingots, it is easy for the visual inspection personnel to misobserve the number of bubbles, and there is the disadvantage of low reliability of the detection results. There is also a method of using an optical microscope to detect the quartz glass ingot. After wiping the outer surface of the quartz glass ingot clean, the optical microscope can magnify the bubbles in the quartz glass ingot to detect the size and number of bubbles. However, the bubbles in the large-size quartz glass ingot produced by gas melting are irregularly distributed, with inconsistent depths and positions, and there are often missed detections during manual detection, so that the quality of the quartz glass ingot cannot be effectively controlled, which in turn affects the subsequent production and processing of quartz glass products, resulting in poor quality of the processed quartz glass products. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art that the bubbles in large-size quartz glass ingots are irregularly distributed, with inconsistent depths and positions, and there are often missed detections during detection, the present invention provides the following technical solutions.

[0005] A qualified detection device for a large-size and few-bubble fused silica glass ingot according to the present invention includes a hollow box body. The front and rear ends of the box body are respectively provided with a quartz inlet connected to a first sealing door and a quartz outlet connected to a second sealing door. A conveyor belt for conveying the fused silica glass ingot is arranged in the inner cavity of the box body. A first lifting member and a second lifting member located above the conveyor belt are sequentially arranged in the front-back direction at the upper part of the box body. A cleaning member is connected to the lower part of the first lifting member. The cleaning member includes a cleaning motor and a dynamic sealing shaft sleeve sleeved on the outer periphery of the output end of the cleaning motor and connected with a vacuum suction pipe. The output end of the cleaning motor passes through the dynamic sealing shaft sleeve and is connected with a cleaning cylinder body communicated with the vacuum suction pipe. A detection member is connected to the lower part of the second lifting member. The detection member includes a detection motor and a turntable connected to the output end of the detection motor. A plurality of vertical plates are connected to the turntable, and detection heads are connected to the lower ends of the vertical plates.

[0006] As a further technical solution, a spiral brush in contact with the fused silica glass ingot is arranged on the inner wall of the cleaning cylinder body.

[0007] As a further technical solution, a spiral soft brush in contact with the fused silica glass ingot is arranged on the inner wall of the cleaning cylinder body.

[0008] As a further technical solution, a top cleaning plate provided with a top cleaning brush is connected to the upper part of the cleaning cylinder body. The top cleaning plate is provided with a plurality of air-permeable holes communicated with the vacuum suction pipe.

[0009] As a further technical solution, a through hole communicated with the vacuum suction pipe is arranged at the upper end of the cleaning cylinder body, and the through hole is communicated to the air-permeable holes.

[0010] As a further technical solution, a cavity is formed between the top cleaning plate and the cleaning cylinder body, and a filter screen is filled in the cavity to prevent impurities from blocking the vacuum suction pipe.

[0011] As a further technical solution, the air-permeable holes are annularly arrayed in the outer peripheral direction of the top cleaning plate, and the brush hair length of the top cleaning brush gradually decreases along the direction of the top cleaning plate towards the air-permeable holes.

[0012] As a further technical solution, a cleaning position and a detection position are respectively arranged in the front-back direction of the conveyor belt.

[0013] As a further technical solution, dust suction pipes provided with a plurality of suction heads and air blowing pipes provided with a plurality of air blowing heads are respectively connected to both sides of the conveyor belt.

[0014] The present invention further includes a qualified detection method for a large-size and few-bubble fused silica glass ingot, including the following steps:

[0015] S1: Wipe the bottom of the fused silica ingot clean and place it at the cleaning position of the conveyor belt. Close the first sealing door and the second sealing door.

[0016] S2: Start the first lifting component and the cleaning component. The first lifting component drives the cleaning cylinder body to descend and sleeved the fused silica ingot into the cleaning cylinder body, and clean the top and outer peripheral wall of the fused silica ingot.

[0017] S3: After cleaning, the first lifting component drives the cleaning component to rise. The conveyor belt transports the fused silica ingot from the cleaning position to the detection position. The second lifting component drives the detection component to descend to detect the fused silica ingot.

[0018] S4: During the detection process, the fused silica ingot remains stationary. The second lifting component and the detection motor drive the detection head to perform omnidirectional detection on the fused silica ingot in the up and down and all around directions. After the detection is completed, take out the fused silica ingot from the quartz outlet.

[0019] Advantages of the present invention: In the box body of the present invention, there are provided a first lifting component connected with a cleaning component and a second lifting component connected with a detection component. The first lifting component can drive the cleaning component to move up and down. During the up and down and rotation process of the cleaning component, the cleaning cylinder body can clean the fused silica ingot in all directions. And during the cleaning process, impurities are directly sucked by the vacuum suction pipe under negative pressure, preventing impurities from polluting the environment inside the box body and ensuring stable detection of the fused silica ingot subsequently. After the fused silica ingot is cleaned, it is sent under the detection component. The second lifting component can drive the detection component to move up and down, and the detection component can rotate around the fused silica ingot to perform omnidirectional detection on the fused silica ingot, preventing missed detection and ensuring the accuracy of the qualified detection result of the fused silica ingot.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0031] Such as Figure 1 , Figure 2 and Figure 3As shown in the figure, a qualified detection device for a large-sized and low-bubble fused silica glass ingot according to the present invention includes a hollow box body 2. A base 1 is provided at the lower part of the box body 2, and the base 1 is used to support the box body 2. A box cover 201 is provided at the upper part of the box body 2. A transparent window 202 and a control panel 203 are provided on one side of the box body 2, which can be used to observe and control the detection work inside the box body 2. Quartz inlets 204 and quartz outlets 205 are respectively provided at the front and rear ends of the box body 2 for the entry and exit of the quartz glass ingot 10 to be detected. The quartz inlet 204 is connected with a first sealing door 206, and the quartz outlet 205 is connected with a second sealing door 207. The first sealing door 206 and the second sealing door 207 can seal the box body 2 to prevent impurities in the external environment from affecting the detection of the quartz glass ingot 10 inside the box body 2. A conveyor belt 3 for conveying the quartz glass ingot 10 is provided in the inner cavity of the box body 2, and the head and tail of the conveyor belt 3 are respectively located at the quartz inlet 204 and the quartz outlet 205.

[0032] As Figure 3 and Figure 4 shown, in a preferred embodiment, a first lifting member 4 and a second lifting member 7 located above the conveyor belt 3 are successively provided in the front-rear direction at the upper part of the box body 2. A cleaning member 5 is connected to the lower part of the first lifting member 4, and a detection member 8 is connected to the lower part of the second lifting member 7. The quartz glass ingot 10 with its bottom wiped clean is placed on the upper part of the conveyor belt 3. As the conveyor belt 3 moves, the quartz glass ingot 10 successively passes below the cleaning member 5 and the detection member 8. After the quartz glass ingot 10 is cleaned by the cleaning member 5, it is then detected by the detection member 8 to detect defects such as the number of bubbles and ripples in it, and to judge whether the quartz glass ingot 10 is qualified.

[0033] In a preferred embodiment, a cleaning position 301 and a detection position 302 are respectively provided in the front-rear direction of the conveyor belt 3. The cleaning position 301 is directly below the cleaning member 5, and the detection position 302 is directly below the detection member 8. After the quartz glass ingot 10 is cleaned at the cleaning position 301, the conveyor belt 3 only needs to move a fixed distance forward, and the quartz glass ingot 10 can be moved to the detection position 302 for detection, ensuring the accuracy of the distance between the quartz glass ingot 10 and the detection member 8.

[0034] Suction pipes 6 and air blowing pipes 9 are respectively connected to both sides of the conveyor belt 3. A plurality of suction heads 601 are provided on the side of the suction pipe 6 facing the conveyor belt 3, and a plurality of air blowing heads 901 are provided on the side of the air blowing pipe 9 facing the conveyor belt 3. The suction pipe 6 is connected to an external suction device, and the air blowing pipe 9 is connected to an external blower. The two cooperate to suck and remove various dusts and impurities on the conveyor belt 3, preventing the dust and impurities from polluting the environment inside the box body 2.

[0035] As Figure 5 and Figure 6As shown, in a preferred embodiment, the first lifting member 4 includes a first fixing plate 401 fixedly connected to the inner wall of the box body 2. The upper part of the first fixing plate 401 is fixedly connected with a first lifting cylinder 402 extending above the box cover 201. The output end of the first lifting cylinder 402 passes downward through the first fixing plate 401 and is connected with a first lifting frame 404. At the same time, a first guiding column 403 is fixedly arranged at the lower part of the first fixing plate 401, and the first guiding column 403 is slidably connected with the first lifting frame 404 to ensure the lifting stability of the first lifting frame 404. The first lifting frame 404 is of a frame structure, and a cleaning motor 501 is fixedly connected inside the first lifting frame 404.

[0036] In a preferred embodiment, the cleaning member 5 includes a cleaning motor 501 located inside the first lifting frame 404. A dynamic seal shaft sleeve 502 is sleeved on the outer periphery of the output end of the cleaning motor 501. The dynamic seal shaft sleeve 502 is connected with a vacuum suction pipe 503, and the vacuum suction pipe 503 is connected to an external dust suction device. The output end of the cleaning motor 501 passes through the dynamic seal shaft sleeve 502 and is connected with a cleaning cylinder 504. The cleaning cylinder 504 is communicated with the vacuum suction pipe 503. Under the vacuum negative pressure of the vacuum suction pipe 503, the dust and impurities inside the cleaning cylinder 504 are sucked and removed.

[0037] In a preferred embodiment, a spiral belt brush 505 in contact with the quartz glass ingot 10 is provided on the inner wall of the cleaning cylinder 504. The spiral belt brush 505 is a spiral belt-shaped structure made of rubber material, which can sweep away the impurities on the outer periphery of the quartz glass ingot 10 and make the impurities spiral upward to be sucked by the vacuum suction pipe 503.

[0038] As Figure 7 shown, in a preferred embodiment, a spiral soft brush 511 in contact with the quartz glass ingot 10 is provided on the inner wall of the cleaning cylinder 504. The spiral soft brush 511 is a spiral-shaped soft brush structure, which is softer in contact with the quartz glass ingot 10, and can sweep away the impurities on the outer periphery of the quartz glass ingot 10 and make the impurities spiral upward to be sucked by the vacuum suction pipe 503, providing an impurity removal effect and ensuring that the quartz glass ingot 10 to be detected is clean and does not affect subsequent detection.

[0039] In a preferred embodiment, a top cleaning plate 507 is connected to the upper part of the cleaning cylinder 504. A top cleaning brush 508 is installed at the lower middle part of the top cleaning plate 507. The top cleaning brush 508 is used to clean the impurities on the top of the quartz glass ingot 10 and is sucked away by the negative pressure of the vacuum suction pipe 503. Specifically, a through hole 506 communicated with the vacuum suction pipe 503 is provided at the upper end of the cleaning cylinder 504, and a plurality of air permeable holes 509 communicated with the through hole 506 are provided on the top cleaning plate 507. At this time, a cavity 510 is formed between the top cleaning plate 507 and the cleaning cylinder 504, and the cavity 510 is filled with a filter screen to prevent large particle impurities from blocking the through hole 506 and the vacuum suction pipe 503.

[0040] In a preferred embodiment, the ventilation holes 509 are annularly arrayed in the circumferential direction of the top-scanning plate 507. The ventilation holes 509 are directly above the inner wall of the cleaning cylinder 504, facilitating the suction of impurities in the cleaning cylinder 504. At the same time, the length of the bristles of the top-scanning brush 508 gradually decreases from the center of the top-scanning plate 507 towards the direction of the ventilation holes 509. With this structure, it is more convenient for the impurities at the top of the fused quartz ingot 10 to be centrifugally cleaned towards the direction of the ventilation holes 509 and be sucked under negative pressure by the vacuum suction pipe 503.

[0041] As Figure 8 shown, in a preferred embodiment, the second lifting member 7 includes a second fixing plate 701 fixedly connected to the inner wall of the box body 2. A second lifting cylinder 702 extending above the box cover 201 is fixedly connected to the upper part of the second fixing plate 701. The output end of the second lifting cylinder 702 passes downward through the second fixing plate 701 and is connected to a second lifting frame 704. At the same time, a second guiding column 703 is fixedly provided at the lower part of the second fixing plate 701. The second guiding column 703 is slidably connected to the second lifting frame 704 to ensure the lifting stability of the second lifting frame 704. The second lifting frame 704 is of a frame structure, and a detection motor 801 is fixedly connected inside the second lifting frame 704.

[0042] In a preferred embodiment, the detection component 8 includes a detection motor 801 located inside the second lifting frame 704. The output end of the detection motor 801 is connected to a turntable 802. The turntable 802 is directly above the detection position 302. The turntable 802 is connected with a plurality of vertical plates 803. The lower ends of the vertical plates 803 are connected with detection heads 804. The detection heads 804 are connected to an external fluorescence detector or X-ray detector, which is used to detect defects such as bubbles and ripples in the fused quartz ingot 10 to detect whether the fused quartz ingot 10 is qualified. In actual detection, the detection motor 801 drives the turntable 802 to rotate, so that the detection heads 804 perform horizontal detection around the fused quartz ingot 10, and the second lifting member 7 drives the detection heads 804 to move up and down to complete the omnidirectional detection of the fused quartz ingot 10.

[0043] The present invention also includes a method for detecting the qualification of a large-size and few-bubble gas-melted fused quartz ingot, which includes the following steps:

[0044] S1: Wipe the bottom of the fused quartz ingot 10 clean and place it at the cleaning position 301 of the conveyor belt 3. Close the first sealing door 206 and the second sealing door 207, start the dust suction pipe 6 and the air blowing pipe 9 to remove the dust in the box body 2. After starting for one minute, close the dust suction pipe 6 and the air blowing pipe 9.

[0045] S2: Start the first lifting component 4 and the cleaning component 5. The first lifting component 4 drives the cleaning cylinder body 504 to descend and sleeved the quartz glass ingot 10 into the cleaning cylinder body 504, and then clean the top and outer peripheral wall of the quartz glass ingot 10. After that, start the dust suction pipe 6 and the air blowing pipe 9 again to remove the dust in the box body 2. After starting for one minute, turn off the dust suction pipe 6 and the air blowing pipe 9.

[0046] S3: After cleaning, the first lifting component 4 drives the cleaning component 5 to rise, and the conveyor belt 3 conveys the quartz glass ingot 10 from the cleaning position 301 to the detection position 302. The second lifting component 7 drives the detection component 8 to descend to detect the quartz glass ingot 10.

[0047] S4: During the detection process, the quartz glass ingot 10 remains stationary. The second lifting component 7 and the detection motor 801 drive the detection head 804 to perform omnidirectional detection on the quartz glass ingot 10 in the up and down and all around directions. After the detection is completed, take out the quartz glass ingot 10 from the quartz outlet 205.
