Description

Technical Field

[0001] This invention relates to the field of quartz crucible testing technology, and in particular to a device for detecting extremely fine cracks on the surface of quartz crucibles. Background Technology

[0002] Quartz crucibles, as high-purity, high-temperature resistant materials, are susceptible to defects such as extremely fine surface cracks, which can affect product performance and safety. These surface cracks are difficult to detect visually, leading to a shift in mainstream industry inspection methods from manual visual inspection to automated visual inspection. For example, high-speed motion cameras are used to photograph the crucible surface for crack identification. While high-speed motion cameras can detect surface cracks, they still have limitations in practical use. One major drawback is the lack of an automated continuous detection mechanism, resulting in lower detection efficiency. Therefore, this paper proposes a device for detecting extremely fine surface cracks in quartz crucibles to address these issues. Summary of the Invention

[0017] 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 protection scope of the present invention.

[0018] like Figure 1-10 As shown, a device for detecting extremely fine cracks on the surface of a quartz crucible includes a base 1 and a mounting frame 2. Two mounting frames 2 are provided, and the two mounting frames 2 are respectively fixedly installed on both sides of the top of the base 1. A drive shaft 3 is rotatably connected inside the mounting frame 2, and two drive shafts 3 are arranged in front and behind. A drive belt 4 is connected between the two drive shafts 3 on the same side. Several arc-shaped placement grooves 8 are equidistantly opened on the surface of the drive belt 4.

[0019] To facilitate automatic inspection of the crucible, a self-inspection mechanism 5 is provided on the top of the base 1. The self-inspection mechanism 5 includes two electric telescopic rods 501, which are fixedly installed on both sides of the top of the base 1. A pusher 502 is fixedly connected between the extended ends of the two electric telescopic rods 501. A support plate 503 is fixedly connected to the top of the pusher 502. Lifting plates 504 are fixedly connected to both sides of the top of the pusher 502. A handle-type ring frame 505 is fixedly connected to the top of the base 1. A movable frame 509 is provided at the bottom of the inner cavity of the handle-type ring frame 505. A column 506 is rotatably installed inside the movable frame 509. A slide rod 507 is rotatably installed inside the handle-type ring frame 505. A spiral groove 508 is opened on the surface of the column 506. An L-shaped frame 510 is fixedly connected to the bottom of the column 506. Several high-speed motion cameras 511 are installed on the surface of the L-shaped frame 510. Limiting rods 512 are slidably provided on the front and rear sides of the inner cavity of the handle ring frame 505, and the bottom end of the limiting rod 512 is fixedly connected to the top of the movable frame 509. A first return spring 513 is fixedly connected between the movable frame 509 and the handle ring frame 505 and on the outer surface of the limiting rod 512.

[0020] To facilitate continuous feeding and inspection of the crucible, the top of the base 1 is equipped with an equidistant feeding mechanism 6 that is used in conjunction with the self-inspection mechanism 5. The equidistant feeding mechanism 6 includes a toothed plate 601, which is slidably disposed on the front side of the pusher 502. There are two toothed plates 601. A gear 602 that meshes with the toothed plate 601 is fixedly connected to the surface of the front drive shaft 3. Guide rollers 603 are rotatably disposed on both sides of the toothed plate 601 through brackets. Guide inclined frames 604 that are used in conjunction with the guide rollers 603 are fixedly connected to both sides of the top of the base 1. Storage sleeves 605 are fixedly connected to both sides of the front side of the pusher 502. A telescopic plate 606 is slidably connected inside the storage sleeve 605. The front side of the telescopic plate 606 is fixedly connected to the rear side of the toothed plate 601. A second return spring 607 is fixedly connected between the telescopic plate 606 and the storage sleeve 605.

[0021] To facilitate prompting staff to promptly retrieve the crucibles after testing, a prompting mechanism 7 is provided on the top of the base 1 and behind the self-inspection mechanism 5. The prompting mechanism 7 includes a prompting frame 701, which is fixedly mounted on the top of the base 1. A push-pull frame 702 is slidably mounted inside the prompting frame 701, and a third return spring 703 is fixedly connected between the push-pull frame 702 and the prompting frame 701. A first control button 704 for use with the electric telescopic rod 501 is installed on the front side of the prompting frame 701. A second control button 705 is installed on the front side of the indicator holder 701, and an audible and visual alarm 706 that is used in conjunction with the second control button 705 is installed on the front side of the indicator holder 701.

[0022] In use, the electric telescopic rod 501 is activated. The extended end of the electric telescopic rod 501 drives the pusher 502, the support plate 503, and the lifting plate 504 to rise. The rising support plate 503 lifts the crucible into the L-shaped frame 510 for detection by the high-speed action camera 511. When the crucible enters the L-shaped frame 510, the corresponding lifting plate 504 contacts the bottom of the movable frame 509 and lifts the movable frame 509. Then the lifting plate 504 continues to lift the movable frame 509, which in turn lifts the column 506. The spiral groove 508 on the surface of the column 506 will press against the slide rod 507 in the handle ring frame 505, causing the column 506 to rotate when it rises. The column 506 drives the L-shaped frame 510 and the high-speed action camera 511 to perform circular shooting detection along the outer surface of the crucible. When the pusher 502 rises, it simultaneously drives the toothed plate 601 to rise via the storage sleeve 605, the telescopic plate 606, and the second return spring 607. The toothed plate 601 drives the guide roller 603 to rise on the rear inclined surface of the guide frame 604. The guide roller 603 presses against the rear inclined surface of the guide frame 604, causing the toothed plate 601 to retract and disengage from the gear 602 until the toothed plate 601 rises with the pusher 502 to the crucible detection completion state. Then, the pusher 502 resets. When the pusher 502 resets, it places the crucible inside the original arc-shaped placement slot 8. After the original arc-shaped placement groove 8 is inside, the guide roller 603 will be at the top of the front inclined surface of the guide frame 604. As the pusher 502 continues to descend and reset, the guide roller 603 will be pressed and moved to the front inclined surface of the guide frame 604. Correspondingly, the guide roller 603 will push the toothed plate 601 forward, so that it is on the meshing trajectory line of the gear 602. Finally, the pusher 502 will continue to descend, which will drive the toothed plate 601 to mesh with the gear 602, causing the gear 602 to drive the transmission shaft 3 and the transmission belt 4 to cooperate. The transmission belt 4 will then transport the next crucible to be tested to the testing station. As the conveyor belt 4 transmits the load, the crucible that has been tested will press the push-pull frame 702 due to the position transmission, causing the push-pull frame 702 to press the first control button 704 and the second control button 705. The first control button 704 will stop the electric telescopic rod 501 when it is pressed, and the second control button 705 will activate the audible and visual alarm 706 to provide an alarm prompt, reminding personnel to take the crucible away as soon as possible.
