Description

Technical Field

[0001] The present invention relates to the technical field of quartz crucible tooling, and particularly to a quartz crucible outer contour size detection tooling. Background Art

[0002] A quartz crucible is a high-temperature resistant container made of high-purity quartz (silicon dioxide), usually used in high-temperature experiments or industrial production, such as melting metals, glass manufacturing, etc. Quartz has a high melting point, good chemical stability, and low expansion coefficient, which make it not easy to deform or break in high-temperature environments. It is commonly used for high-temperature heating in laboratories, such as sample processing in a muffle furnace, and also for semiconductor manufacturing, glass fiber production, precious metal melting, etc. in industry. When performing the outer contour detection of a quartz crucible, a measuring device featuring an optical method is generally used for measurement, which can measure its irregular surface or contour.

[0003] The quartz crucible is the core container for the production of semiconductor silicon single crystals, photovoltaic silicon ingots, etc. Its outer contour dimensions, such as outer diameter, roundness, straightness, wall thickness uniformity, etc., determine the installation accuracy and heat conduction efficiency of the crucible in the heating device. If the outer diameter exceeds the tolerance range, it may lead to uneven gaps between the crucible and the heating coil and the thermal insulation layer, causing local overheating or abnormal heat dissipation, resulting in disordered flow of the silicon melt, and ultimately leading to crystal defects. When the image recognition algorithm of the machine vision system detects defects, the quartz crucible needs to be placed in a relatively centered and appropriate position, and then the whole crucible is driven to rotate by a turntable set at the bottom, so as to perform visual detection on the four sides of the crucible. Since the crucible is not centered when placed, it causes eccentricity during rotation, and the images taken may have position deviations, and the edge part may exceed the field of view or the center may shift, affecting the detection accuracy. In addition, vibrations will be generated when the turntable rotates, and the position of the crucible will shift to a certain extent, resulting in blurred images. Summary of the Invention

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0033] Please refer to Figures 1 to 8 , a detection tool for the outer contour dimensions of a quartz crucible, comprising: a base 1, on which a laser detector 2 is provided. The laser detector 2 calculates the offset between the outer wall of the crucible and the theoretical dimensions in real time through the principle of laser interference. A movable disk 3 is movably provided on the base 1. The movable disk 3 is horizontally arranged and is controlled to rotate by a driving motor below to realize 360-degree detection of the crucible. A fixed shaft 4 is fixedly provided on the movable disk 3. It further includes: a fixing mechanism 5, which is provided on the base 1 and the fixed disk 6. The fixing mechanism 5 includes a fixed disk 6 fixedly provided on the fixed shaft 4. A plurality of slide grooves 7 are formed on the fixed disk 6. A slide block 8 is slidably arranged in the slide groove 7. A block 9 is movably provided above the slide block 8. The fixing mechanism 5 is used to fix the inner wall of the quartz crucible

[0034] The quartz crucible is centered and fixed on the base 1 through the synchronous movement of the fixing mechanism 5, ensuring that the crucible maintains its central position during the detection process, reducing offset or rotation, thereby reducing measurement errors. This not only improves the detection accuracy but also optimizes the operation simplicity. Through the centering and fixing of the quartz crucible and the precise detection of the laser detector 2, deviations in the size or shape of the crucible can be detected in a timely manner, enabling timely adjustment or replacement, ensuring the quality stability of the crucible. The inner wall of the quartz crucible is supported and fixed by the abutting block 9, completely exposing the outer surface of the quartz crucible to the detection environment, avoiding blocking some areas of the outer surface of the crucible. The laser detector 2 can scan the entire outer surface without dead angles, improving the imaging quality of defects such as cracks and bubbles, eliminating the need to adjust the position of the crucible, and reducing the repeated detection rate.

[0035] Please refer to Figures 1 to 8 , a detection tool for the outer contour size of a quartz crucible, further comprising: an adjusting mechanism 25, the adjusting mechanism 25 is located on the fixing mechanism 5, the adjusting mechanism 25 includes a through hole 26 penetrating through the abutting block 9, a movable column 27 is arranged in the through hole 26, the movable column 27 is slidably connected to the abutting block 9, and the adjusting mechanism 25 is used for adapting and adjusting according to the inner wall size of the quartz crucible;

[0036] By adjusting the position of the abutting block 9 by the adjusting mechanism 25 according to the inner wall size of the quartz crucible, it is ensured that the detection tool can adapt to quartz crucibles of different specifications. When the size of the quartz crucible changes, the movable column 27 slides correspondingly in the through hole 26, releasing the limit of the abutting block 9, thereby adjusting the position of the abutting block 9 to ensure that the detection tool is always in close contact with the inner wall of the quartz crucible, achieving effective fixation and support.

[0037] Further, specifically please refer to Figures 1 to 7 , the fixing mechanism 5 further includes a rotating disk 11 rotatably arranged on the outer surface of the fixed shaft 4, a plurality of through grooves 12 are penetrated and clamped on the rotating disk 11, the through grooves 12 are arc-shaped, the through grooves 12 are arranged in an array with the center of the rotating disk 11 as the reference point, and a plurality of first teeth 20 are fixedly arranged on the side wall of the rotating disk 11. The fixing mechanism 5 further includes a connecting shaft 13 fixedly arranged on the base 1, a driving shaft 14 is rotatably arranged on one side of the connecting shaft 13 on the base 1, and an external drive is connected to the driving shaft 14. A rotating block 15 is fixedly arranged on the outer surface of the driving shaft 14, an eccentric shaft 16 is eccentrically fixed on the rotating block 15, and a swing rod 17 is rotatably arranged on the outer surface of the connecting shaft 13. A straight groove 18 is penetrated through the swing rod 17, the inner wall of the straight groove 18 is slidably connected to the outer surface of the eccentric shaft 16, a limiting block 19 is fixedly arranged at the bottom of the eccentric shaft 16, and a plurality of second teeth 21 are arranged at the end of the swing rod 17, and the second teeth 21 are meshed with the first teeth 20.

[0038] Among them, a fixed rod 10 is fixedly arranged at the bottom of the slider 8. The fixed rod 10 is located in the through groove 12. Arc surfaces A22 and arc surfaces B23 are symmetrically arranged on the slider 8. A horizontal plane 24 is arranged between the arc surfaces A22 and the arc surfaces B23. The arc surfaces A22 and the arc surfaces B23 are concentrically arranged. The arc surfaces A22 and the arc surfaces B23 can fix a quartz crucible with a circular inner wall, so that the abutting block 9 contacts the inner wall of the circular quartz crucible evenly, reducing vibration and offset during the fixing process, thereby improving the detection accuracy. The fixing of a square crucible can be realized through the horizontal plane 24, improving the compatibility of the equipment.

[0039] By driving the driving shaft 14 to drive the rotating block 15 to rotate, further enabling the eccentric eccentric shaft 16 to slide in the straight groove opening 18, causing the swing rod 17 to drive the second tooth 21 to swing. During the swinging process, the first tooth 20 meshing with the second tooth 21 drives the rotating disk 11 to rotate accordingly. Since the fixed rod 10 at the bottom of the abutting block 9 is located in the through groove 12 of the rotating disk 11, when the rotating disk 11 rotates, it will drive the fixed rod 10 to slide in the through groove 12. Since the through groove 12 is arc-shaped and circumferentially arranged, the slider 8 in the chute 7 of the fixed disk 6 drives the abutting block 9 to move synchronously. During the process of the abutting block 9 expanding outwards, it supports and fixes the inner wall of the quartz crucible, avoiding vibration and offset of the crucible during the detection process, thereby improving the detection accuracy, realizing the automatic fixing and detection of the quartz crucible, reducing the need for manual intervention, not only improving the detection speed but also reducing human errors. Ensure that the crucible remains in the central position during the detection process, reducing offset or rotation, thereby reducing measurement errors.

[0040] Furthermore, specifically refer to Figure 1 and Figures 6 to 8 , the adjusting mechanism 25 further includes a movable groove 28 on the slider 8. A fixing piece 29 is movably arranged in the movable groove 28. A plurality of first convex blocks 30 are symmetrically arranged on the fixing piece 29. The first convex blocks 30 are arranged in a triangular shape. The fixing piece 29 is fixedly arranged on the outer surface of the movable column 27. A plurality of grooves 31 are symmetrically arranged in the movable groove 28. A plurality of second convex blocks 32 are fixedly arranged in the grooves 31. The second convex blocks 32 are arranged in a triangular shape. The second convex blocks 32 are mutually adapted to the first convex blocks 30. After the first convex blocks 30 are butted with the second convex blocks 32 in the movable groove 28 of the slider 8, a one-way locking structure is formed.

[0041] Among them, a movable hole 33 is opened at the bottom of the movable column 27. A fixing column 34 is slidably arranged on the inner wall of the movable hole 33. A movable piece 35 is fixedly arranged at the bottom of the fixing column 34. The outer surface of the movable piece 35 slides in the movable groove 28. A spring 36 is arranged between the movable piece 35 and the fixing piece 29. The spring 36 is commonly sleeved on the outer surfaces of the movable column 27 and the fixing column 34, providing an upward restoring force to ensure that the first convex blocks 30 and the second convex blocks 32 are tightly engaged.

[0042] By pressing the movable column 27 on the pressing block 9, the movable column 27 is urged to slide and descend in the through hole 26. During the descending process, the movable column 27 slides on the outer surface of the fixed column 34 through the movable hole 33. During the descending process of the movable column 27, the fixed piece 29 will squeeze the spring 36, causing the spring 36 to compress. At the same time, the first convex block 30 on the fixed piece 29 gradually moves away from the second convex block 32. At this time, the pressing block 9 can be slid in the movable groove 28 to a suitable position. When the pressing block 9 reaches the suitable position, the movable column 27 is released, and the pressing force of the spring 36 gradually disappears, causing it to squeeze the fixed piece 29, and then driving the first convex block 30 on the fixed piece 29 to re-engage between the second convex blocks 32 to form a lock. This operation enables the position of the pressing block 9 to be adjusted according to the inner diameter of the quartz crucible. When the size of the quartz crucible changes, the movable column 27 slides correspondingly in the through hole 26, causing the limit of the pressing block 9 to be released, thereby adjusting the position of the pressing block 9 to ensure that the detection tooling is always in close contact with the inner wall of the quartz crucible, achieving effective fixation and support.

[0043] Through all the above embodiments, the working principle of the present invention is as follows:

[0044] First, place the quartz crucible upside down above the fixed disk 6. Then, start the external drive of the drive shaft 14. Drive the rotating block 15 to rotate through the drive shaft 14, so that the eccentric eccentric shaft 16 slides in the straight slot 18, causing the swing rod 17 to drive the second tooth 21 to swing. During the swinging process, the first tooth 20 meshing with the second tooth 21 drives the rotating disk 11 to rotate accordingly. Since the fixed rod 10 at the bottom of the abutting block 9 is located in the through slot 12 of the rotating disk 11, when the rotating disk 11 rotates, it will drive the fixed rod 10 to slide in the through slot 12. Since the through slot 12 is arc-shaped and circularly arranged, the slider 8 in the chute 7 of the fixed disk 6 drives the abutting block 9 to move synchronously. During the outward expansion process of the abutting block 9, the inner wall of the quartz crucible is supported and fixed, avoiding the vibration and deviation of the crucible during the detection process, thus improving the detection accuracy, realizing the automatic fixing and detection of the quartz crucible, reducing the need for manual intervention, not only improving the detection speed but also reducing human errors. Ensure that the crucible remains in the central position during the detection process, reducing deviation or rotation, thereby reducing measurement errors; when quartz crucibles of different sizes need to be fixed, by pressing the movable column 27 on the abutting block 9, the movable column 27 is prompted to slide and descend in the through hole 26. During the descending process, the movable column 27 slides on the outer surface of the fixed column 34 through the movable hole 33. During the descending process of the movable column 27, the fixed piece 29 will squeeze the spring 36, causing the spring 36 to compress. At the same time, the first convex block 30 on the fixed piece 29 gradually moves away from the second convex block 32. At this time, the abutting block 9 can be slid in the movable slot 28 to a suitable position. After the abutting block 9 reaches the suitable position, release the movable column 27. The squeezing force of the spring 36 gradually disappears, causing it to squeeze the fixed piece 29, and then driving the first convex block 30 on the fixed piece 29 to re-engage between the second convex blocks 32 to form a lock. This operation enables the position of the abutting block 9 to be adjusted according to the inner wall diameter of the quartz crucible. When the size of the quartz crucible changes, the movable column 27 slides correspondingly in the through hole 26, causing the limit of the abutting block 9 to be released, thereby adjusting the position of the abutting block 9 to ensure that the detection tooling is always in close contact with the inner wall of the quartz crucible, realizing effective fixing and support.

[0045] Those of ordinary skill in the art should understand that the discussion of any embodiment above is only exemplary. Under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail.
