Description

Technical Field

[0001] This utility model relates to the field of fused silica production and processing, and in particular to an observation device for detecting fused silica samples. Background Technology

[0002] In the field of precision machining of fused silica particles, particle shape is a key parameter determining product performance and directly affects its application in high-end scenarios such as semiconductor wafer manufacturing and optical glass melting. Currently, in the production process of grinding quartz particles, the detection of particle shape generally adopts offline sampling inspection. This requires manual sampling from the production line at regular intervals, and multiple processes such as sample preparation, dispersion, and microscopic imaging are needed to obtain morphological data such as particle contour and edge sharpness.

[0003] This traditional detection method has significant drawbacks: First, manual sampling has a long cycle and cannot be followed up in a timely manner during production. Second, traditional observation equipment relies on static sample analysis and cannot track dynamically flowing quartz particles on the production line in real time. The real-time evolution characteristics of particle shape (such as the roundness of edges and the formation of surface defects) are difficult to capture effectively, resulting in a lack of immediate feedback for process parameter adjustments. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide an observation device for detecting fused silica samples, which can detect the particle shape of ground fused silica sand in a timely manner without the need for manual sampling.

[0006] To achieve the above objectives, this utility model proposes an observation device for detecting fused silica samples, comprising a lens assembly, a hopper assembly, and a support assembly. The support assembly includes a base plate and a rotating plate, with the rotating plate rotatably mounted on the upper surface of the base plate. The hopper assembly is mounted on the upper surface of the rotating plate and includes a hopper and a hopper door panel. The hopper is mounted on the rotating plate, and the hopper door panel is hinged to the vertical side wall of the hopper. The lens assembly is positioned above the hopper and includes an image acquisition device, an eyepiece, and an objective lens. The eyepiece and objective lens are combined and positioned above the hopper, and the image acquisition device is mounted on the eyepiece.

[0007] Furthermore, an imaging adjustment assembly is provided on the base plate for adjusting the lens assembly to achieve clear imaging. The imaging adjustment assembly includes an adjustment arm, a lead screw, and a lens bracket. The lens bracket is connected to the lens assembly. The adjustment arm is mounted on the base plate. A sliding groove is provided on the inner side of the adjustment arm. A lead screw seat is provided on the inner side of the sliding groove. The lead screw is threaded through the lead screw seat. A lead screw motor is provided at the top of the lead screw. A slider is provided on the outer side of the lead screw seat. The slider is connected to the lens bracket.

[0008] Furthermore, a transparent support platform is provided at the bottom of the hopper, and a supplementary light is provided at the bottom of the transparent support platform. The bottom of the hopper door panel is elastically hinged to the hopper via an elastic hinge. Two hopper door panels are provided on each hopper, and the two hopper door panels are located at the inlet end and the outlet end of the hopper, respectively.

[0009] Furthermore, the hopper is also equipped with a feeding assembly, including a feeding pipe and a scraper, wherein the feeding pipe is located above the hopper and the scraper is located at the bottom of the feeding pipe.

[0010] Furthermore, the hopper is also equipped with a hopper cleaning assembly, including a cleaning rod, a brush head, and a top plate, wherein the cleaning rod is located above the hopper, the brush head is located at the bottom of the cleaning rod, and the top plate is located on one side of the cleaning rod.

[0011] Furthermore, a drive motor is provided on the base disk, and a drive wheel is provided on the output shaft of the drive motor, with the drive wheel in contact with the inner wall of the rotating disk.

[0012] Beneficial effects: This utility model sets a hopper assembly on a turntable. The hopper receives the quartz sand sample from the grinder. After the hopper rotates to the lens assembly, the eyepiece and objective lens collect images of the quartz sand particles in the hopper and acquire the images through an imaging collector. As the turntable continues to rotate, the hopper collects new quartz sand samples again. This allows for timely detection of the particle shape of the ground molten quartz sand without the need for manual sampling.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The observation device for detecting fused silica samples according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, the observation device for detecting fused silica samples provided in this embodiment of the present invention includes a lens assembly 2, a hopper assembly 5, and a support assembly 6. The support assembly 6 includes a base plate 62 and a rotating plate 61. The rotating plate 61 is rotatably disposed on the upper surface of the base plate 62, and the hopper assembly 5 is disposed on the upper surface of the rotating plate 61.

[0019] The hopper assembly 5 includes a hopper 51 and a hopper door panel 52, wherein the hopper 51 is mounted on a rotating disk 61, and the hopper door panel 52 is hinged to the vertical side wall of the hopper 51.

[0020] Lens assembly 2 is positioned above the material hopper 51. Lens assembly 2 includes an image acquisition device 21, an eyepiece 22, and an objective lens 23. The eyepiece 22 and objective lens 23 are combined and positioned above the moving path of the material hopper 51, and the image acquisition device 21 is mounted on the eyepiece 22. It should be noted that the image acquisition device 21 can be an electronic camera used to directly acquire the image from the eyepiece 22. The eyepiece 22 and objective lens 23 are combined to form a magnifying glass for magnifying the quartz sand sample.

[0021] Specifically, in use, the observation device of this application rotates the hopper 51 via the rotating disk 61. When the hopper 51 enters below the discharge end of the grinder, it receives the quartz sand sample from the grinder. The hopper 51 then rotates to the lens assembly 2, where the eyepiece 22 and objective lens 23 capture images of the quartz sand particles within the hopper 51. These images are then acquired by the image acquisition device 21 to detect the shape of the quartz sand sample. Subsequently, the rotating disk 61 continues to rotate, and the hopper 51 re-enters the discharge end of the grinder, collecting new quartz sand samples. This cycle repeats continuously, enabling timely detection of the ground shape of the molten quartz sand without the need for manual sampling.

[0022] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, an imaging adjustment component 1 is provided on the base plate 62 for adjusting the lens assembly 2 to achieve clear imaging. The imaging adjustment component 1 includes an adjustment arm 11, a lead screw 14, and a lens bracket 17. The lens bracket 17 is connected to the lens assembly 2, and the adjustment arm 11 is provided on the base plate 62.

[0023] The inner side of the adjusting arm 11 is provided with a sliding groove 15, the inner side of the sliding groove 15 is provided with a screw seat 16, the screw 14 is threaded through the screw seat 16, the top of the screw 14 is provided with a screw motor 13, the outer side of the screw seat 16 is provided with a slider 12, and the slider 12 is connected to the lens bracket 17.

[0024] Specifically, when different magnifications need to be adjusted, after changing the eyepiece 22, the distance between the objective lens 23 and the quartz sand sample needs to be adjusted. At this time, the lead screw motor 13 drives the lead screw 14 to rotate, and then the lead screw 14 engages with the lead screw seat 16, causing the lead screw seat 16 to move up and down. This, in turn, drives the lens bracket 17 and the lens assembly 2 to adjust their positions synchronously up and down until the imaging acquisition device 21 forms a clear image, at which point the adjustment of the position of the lens assembly 2 stops. This is used to adjust the magnification of the sample.

[0025] In one embodiment of this utility model, such as Figure 2 As shown, a transparent support platform 54 is provided at the bottom of the hopper 51, and a supplementary light 55 is provided at the bottom of the transparent support platform 54.

[0026] Specifically, during the collection process of the quartz sand sample in the hopper 51, the supplementary light 55 at the bottom of the transparent support platform 54 provides high-intensity illumination, improving the clarity of the image and making the edge contour of the quartz sand clearer.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, the bottom of the hopper door panel 52 is elastically hinged to the hopper 51 by setting an elastic hinge 53. Two hopper door panels 52 are set on each hopper 51, and the two hopper door panels 52 are located at the feeding end and the discharging end of the hopper 51, respectively.

[0028] Specifically, as the hopper 51 rotates on the rotating disk 61, the lens assembly 2 can easily push open the hopper door 52 to enter and leave the inside of the hopper 51, ensuring that the lens assembly 2 can smoothly detect the quartz sand sample in the hopper 51. The addition of the hopper door 52 also prevents the quartz sand sample in the hopper 51 from overflowing during the transfer process.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a material feeding assembly 4 is also provided on the hopper 51. The material feeding assembly 4 includes a material feeding pipe 42 and a scraper plate 43. The material feeding pipe 42 is located above the hopper 51, and the scraper plate 43 is located at the bottom of the material feeding pipe 42.

[0030] Specifically, in the feeding assembly 4, the feeding pipe 42 can be connected to the discharge end of the quartz sand grinder. The feeding pipe 42 is supported by the feeding bracket 41. After the quartz sand sample is put into the hopper 51, as the hopper 51 moves on the rotating disk 61, the scraping plate 43 at the bottom of the feeding pipe 42 flattens the quartz sand sample in the hopper 51, which is more conducive to the lens assembly 2 to clearly acquire and image.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a hopper cleaning assembly 3 is also provided on the hopper 51. The hopper cleaning assembly 3 includes a cleaning rod 32, a brush head 34 and a top plate 33. The cleaning rod 32 is set above the hopper 51 through a cleaning bracket 31, the brush head 34 is set at the bottom of the cleaning rod 32, and the top plate 33 is set on one side of the cleaning rod 32.

[0032] Specifically, after the imaging acquisition of the quartz sand sample in the hopper 51 is completed, as the hopper 51 continues to move, when the hopper 51 enters the cleaning rod 32, the brush head 34 at the bottom of the cleaning rod 32 cleans out the quartz sand sample from the hopper 51. Furthermore, the top plate 33 on one side of the cleaning rod 32 opens the hopper door 52 in advance, facilitating the brush head 34 to transfer the quartz sand sample from the inside of the hopper 51. This keeps the hopper 51 clean and ready for continued acquisition of new quartz sand samples.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a drive motor 63 is provided on the base disk 62, and a drive wheel 64 is provided on the output shaft of the drive motor 63. The drive wheel 64 is in contact with the inner wall of the rotating disk 61.

[0034] Specifically, during the rotation of the rotating disk 61, the drive motor 63 drives the drive wheel 64 to rotate, and the drive wheel 64 drives the rotating disk 61 to rotate.

[0035] To clearly illustrate the above embodiments, refer to Figure 1 and Figure 2 The specific working principle of the observation device for detecting fused silica samples of this utility model is as follows: In use, the drive motor 63 drives the drive wheel 64 to rotate, which in turn drives the rotating disk 61 to rotate. The rotating disk 61 drives the hopper 51 to rotate. When the hopper 51 enters below the discharge end of the grinder, the discharge pipe 42 is connected to the discharge end of the quartz sand grinder. The discharge pipe 42 puts the quartz sand sample into the hopper 51. As the hopper 51 moves on the rotating disk 61, the scraper plate 43 at the bottom of the discharge pipe 42 flattens the quartz sand sample in the hopper 51.

[0036] Subsequently, the hopper 51 rotates to the bottom of the lens assembly 2, allowing the lens assembly 2 to easily push open the hopper door 52 and enter the inside of the hopper 51. At this time, the eyepiece 22 and objective lens 23 acquire images of the quartz sand particles inside the hopper 51, and the images are then acquired by the imaging acquisition device 21 to detect the shape of the quartz sand sample. During the acquisition process, the supplementary light 55 at the bottom of the transparent support platform 54 provides high-intensity illumination, improving the clarity of the image and making the edge contour of the quartz sand more clearly visible.

[0037] The rotating disc 61 then continues to rotate. When the hopper 51 enters the cleaning rod 32, the brush head 34 at the bottom of the cleaning rod 32 cleans out the quartz sand sample from the hopper 51. The top plate 33 on one side of the cleaning rod 32 then opens the hopper door 52 in advance, allowing the brush head 34 to transfer the quartz sand sample from inside the hopper 51. This keeps the hopper 51 clean, ready for collecting new quartz sand samples. The hopper 51 then re-enters the bottom of the discharge pipe 42, and new quartz sand samples are collected. This cycle repeats, allowing for timely detection of the ground shape of the molten quartz sand without the need for manual sampling.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
