Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, specifically relating to a fully automatic visual defect detection device for platinum crucibles. Background Technology

[0002] Crucibles are widely used in high-temperature smelting, chemical experiments and other fields. They are high-temperature refractory containers whose main function is to hold molten or heated substances. In actual use, crucibles are often exposed to harsh environments such as high temperature and high pressure, which can easily lead to cracks, corrosion and dents, directly affecting the performance and safety of the crucible, and may even cause the crucible to break or fail.

[0003] Currently, traditional methods for inspecting platinum crucibles mostly involve manual visual inspection combined with manual weighing. Manual inspection suffers from low accuracy and efficiency, making it unsuitable for the quality inspection needs of batch crucibles leaving the factory. Existing automated inspection equipment mostly only allows for single-sided image acquisition, capturing images of the inner wall when the crucible opening is facing upwards and images of the outer wall when the crucible is flipped over. This fails to simultaneously perform full-area visual inspection of both the inner and outer walls of the crucible, as well as weight measurement. Therefore, a fully automated visual defect detection device for platinum crucibles is proposed. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a fully automatic visual defect detection device for platinum crucibles, comprising: a frame with a housing mounted on it, the housing forming a detection cavity; a weighing assembly fixedly mounted on the frame and placed within the detection cavity, the weighing assembly being used to detect the weight of the crucible; a first detection assembly mounted on the housing and located within the detection cavity, the first detection assembly being used to acquire images of the inner wall of the crucible; a second detection assembly movably disposed within the detection cavity, the second detection assembly being used to acquire images of the outer wall of the crucible; and an annular guide assembly connected to the second detection assembly, the annular guide assembly being used to drive the second detection assembly to perform intermittent indexing rotation around the crucible at fixed points in the circumferential direction.

[0005] In another preferred embodiment, the annular guide assembly includes: an annular disk, a connecting frame, a fixing frame, and a drive assembly. The annular disk is rotatably disposed within the detection chamber and arranged around the crucible. The connecting frame is fixedly mounted on the annular disk and is used to connect the second detection assembly. The fixing frame is fixedly disposed within the detection chamber and is used to provide rotational support for the annular disk. The drive assembly is drively connected to the annular disk and is used to drive the annular disk to rotate.

[0006] In another preferred embodiment, the drive assembly includes a drive motor and a drive gear disk. The output shaft of the drive motor is connected to the drive gear disk for transmission. The drive motor is used to drive the drive gear disk to rotate. The outer edge of the drive gear disk is fixedly provided with a set of drive teeth. The sidewall of the annular disk is evenly arranged with multiple sets of driven teeth that mesh with the set of drive teeth. The rotation of the drive gear disk drives the annular disk to rotate intermittently in increments.

[0007] In another preferred embodiment, at least three sets of driven gears are provided, and a friction block is fixedly connected to the outer wall of the annular disk. The friction block is disposed between two adjacent sets of driven gears, and the outer wall of the friction block slides in engagement with the outer wall of the driving gear disk.

[0008] In another preferred embodiment, the fixing frame includes: an annular guide rail arranged parallel to the annular disk and a plurality of connecting rods. The annular guide rail is fixedly connected to the inner wall of the detection cavity. An annular groove is formed at the lower end of the annular guide rail along the circumferential direction. One end of the connecting rod is fixedly connected to the annular disk, and the other end of the connecting rod is connected to a locking block. The locking block is slidably connected to the annular groove.

[0009] In another preferred embodiment, the weighing assembly includes a weighing device and a weighing platform, the weighing device being fixedly mounted on the frame, and the weighing platform being fixedly mounted on the weighing device, the weighing platform being used to place the crucible.

[0010] In another preferred embodiment, the housing includes four fixed sides and one movable side, with a drive cylinder connected to the movable side, which drives the movable side to move and unfold.

[0011] In another preferred embodiment, the first detection component includes a first camera and a first light source, both of which are fixedly mounted on the housing, and the first light source is located at the shooting end of the first camera.

[0012] In another preferred embodiment, the second detection component includes a second camera and a second light source, both of which are fixedly mounted on the connecting frame, with the second light source located at the shooting end of the second camera.

[0013] The beneficial effects of this invention are as follows: (1) The present invention detects the weight of the crucible by setting a weighing component, and sets a first detection component and a second detection component to collect images of the inner wall and outer wall of the crucible respectively. The second detection component is driven to rotate around a fixed point by a ring guide component, so that the detection can be completed in all directions without moving the crucible.

[0014] (2) The present invention sets up a toothed disc meshing intermittent indexing transmission structure, which, together with the friction block sliding locking structure, enables the annular disc to drive the outer wall detection camera to stop and take pictures at a fixed point. The positioning accuracy is high and the stability is good, effectively avoiding the problem of blurry dynamic shooting and ensuring the accuracy of defect identification.

[0018] To better understand the present invention, various aspects of the invention will be described in more detail with reference to the accompanying drawings.

[0019] Please see Figure 1-5 This paper illustrates a preferred embodiment of a fully automatic visual defect detection device for platinum crucibles, which mainly consists of a frame 10, a housing 11, a weighing component 20, a first detection component 30, a second detection component 40, and an annular guide component 50. The frame 10 provides support for the entire device, and the housing 11 is mounted on the frame 10. The interior of the housing 11 is hollow, forming a sealed detection chamber 12. The weighing component 20, the first detection component 30, and the second detection component 40 are all disposed within the detection chamber 12, providing a stable detection environment that is dustproof and light-proof for crucible detection.

[0020] The weighing assembly 20 is fixedly installed on the frame 10. The crucible, with its opening facing upwards, is placed on the weighing assembly 20. The weighing assembly 20 detects the weight of the crucible and uses the weight change to determine whether there are any residues or damage inside the crucible. The first detection assembly 30 is fixedly installed inside the detection chamber 12, above the weighing assembly 20, and can directly capture images of the inner wall of the crucible placed on the weighing assembly 20. The second detection assembly 40 is movably disposed inside the detection chamber 12. The annular guide assembly 50 is connected to the second detection assembly 40. The annular guide assembly 50 drives the second detection assembly 40 to rotate intermittently around the crucible in a circumferential manner, allowing the second detection assembly 40 to capture images of the outer wall of the crucible multiple times, thereby achieving omnidirectional detection of the inner and outer walls of the crucible.

[0021] Furthermore, in a preferred embodiment, the annular guide assembly 50 includes: an annular disk 51, a connecting frame 52, a fixing frame 53, and a drive assembly 60. The annular disk 51 is rotatably disposed within the detection chamber 12 and arranged around the crucible. The connecting frame 52 is fixedly mounted on the annular disk 51. The fixing frame 53 is fixedly disposed within the detection chamber 12 and is used to provide rotational support for the annular disk 51. The drive assembly 60 is drively connected to the annular disk 51 and is used to drive the annular disk 51 to rotate. The second detection assembly 40 is fixedly mounted on the connecting frame 52 and can rotate synchronously with the annular disk 51.

[0022] Furthermore, in a preferred embodiment, the drive assembly 60 provides power to the annular disk 51. The drive assembly 60 includes a drive motor 61 and a drive gear disk 62. The output shaft of the drive motor 61 is connected to the drive gear disk 62 for transmission. The drive motor 61 drives the drive gear disk 62 to rotate. A drive gear set 63 is fixedly arranged on the outer edge of the drive gear disk 62. Multiple sets of driven gear sets 64 that mesh with the drive gear sets 63 are evenly arranged on the sidewall of the annular disk 51. The rotation of the drive gear disk 62 drives the annular disk 51 to rotate intermittently. Specifically, to ensure that the rotation of the drive gear set 63 is not too fast, a reducer is connected between the drive motor 61 and the drive gear disk 62 to make the drive gear disk 62 rotate slowly. The diameter of the drive gear disk 62 is smaller than the diameter of the annular disk 51. When the drive gear set 63 and the driven gear set 64 mesh, a two-stage reduction can be achieved, further slowing down the rotation speed of the annular disk 51 and improving the stability of fixed-point shooting.

[0023] Specifically, a window is provided on one side of the housing 11, a portion of the active gear 62 passes through the window and is located on the outside of the housing 11, and the drive motor 61 is also located on the outside of the housing 11. A connecting plate serves as the bottom support for the active gear 62 and the drive motor 61, and the connecting plate is fixedly connected to the outer wall of the housing 11.

[0024] Furthermore, as a preferred embodiment, the driven gear assembly 64 is provided with at least three sets to ensure complete imaging of the outer wall of the crucible.

[0025] Furthermore, in a preferred embodiment, a friction block 65 is fixedly connected to the outer wall of the annular disk 51. The friction block 65 is disposed between two adjacent sets of driven gears 64, and the outer wall of the friction block 65 slides in engagement with the outer wall of the driving gear disk 62. When the driving gear set 63 meshes with the driven gear set 64, it drives the annular disk 51 to rotate and index. When the driving gear set 63 rotates out of the meshing range, the friction block 65 slides against the outer wall of the driving gear disk 62, limiting its movement and causing the annular disk 51 to quickly lock at a fixed point and remain stationary. At this time, the second detection component 40 completes the image acquisition of the outer wall of the crucible. Specifically, the outer wall of the friction block 65 is in partial contact with the outer wall of the driving gear disk 62, and the edges of the friction block 65 are all inwardly curved surfaces, which do not affect the rotation of the driving gear set 63 and the annular disk 51. By using intermittent indexing and fixed-point locking shooting, each image of the outer wall is ensured to be clear and complete, avoiding blurring during dynamic shooting. By stitching together multiple fixed-point shooting images, 360° defect detection without blind spots is achieved on the outer wall of the crucible.

[0026] Furthermore, in a preferred embodiment, the fixing frame 53 is disposed within the detection cavity 12 and mainly consists of an annular guide rail 531 and multiple connecting rods 532. The annular guide rail 531 is arranged parallel to the annular disk 51 and fixed to the inner wall of the detection cavity 12. An annular groove 533 is formed circumferentially at the lower end of the annular guide rail 531. One end of the connecting rod 532 is fixedly connected to the annular disk 51, and the other end of the connecting rod 532 is connected to a locking block 534. The locking block 534 is engaged in the annular groove 533 and forms a sliding connection. During the rotation of the annular disk 51, the locking block 534 slides circumferentially along the annular groove 533, axially limiting and radially guiding the annular disk 51, effectively preventing the annular disk 51 from shifting or shaking during operation, and improving the stability of the equipment operation.

[0027] Furthermore, as a preferred embodiment, the weighing assembly 20 includes: a weighing device 21 and a weighing platform 22. The weighing device 21 is fixedly mounted on the frame 10, and the weighing platform 22 is fixedly mounted on the weighing device 21. The weighing platform 22 is used to place the crucible. The weighing device 21 accurately detects the overall weight of the crucible, and the weight data is used to determine whether there are any residues or damage inside the crucible.

[0028] Furthermore, in a preferred embodiment, the housing 11 includes four fixed sides and one movable side. The four fixed sides, one movable side, and the upper surface of the frame 10 enclose a detection cavity 12. A drive cylinder 13 is connected to the movable side, which drives the movable side to move and unfold. Specifically, the movable side is slidably connected to the sidewalls of the two adjacent fixed sides. The lower end of the movable side is fixedly connected to the output end of the drive cylinder 13, allowing the movable side to move up and down via the drive cylinder 13. A discharge port is provided through the movable side for easy loading and unloading of the crucible. When loading and unloading materials, the drive cylinder 13 controls the movable side to move and open, facilitating the loading and unloading of the crucible by the operator or robot. During the detection process, the movable side closes, creating a sealed environment in the detection cavity 12 to prevent external light and dust from interfering with the detection accuracy.

[0029] Furthermore, in a preferred embodiment, the first detection component 30 includes a first camera 31 and a first light source 32. Both the first camera 31 and the first light source 32 are fixedly mounted on the housing 11, and the first light source 32 is located at the imaging end of the first camera 31 to provide supplementary lighting for the first camera 31. Specifically, a mounting frame is assembled inside the detection cavity 12 using rods to fix the first camera 31 and the first light source 32 to the mounting frame, so that the first camera 31 and the first light source 32 are suspended above the weighing platform 22, with the imaging end of the first camera 31 facing downwards.

[0030] Furthermore, in a preferred embodiment, the second detection component 40 includes a second camera 41 and a second light source 42. Both the second camera 41 and the second light source 42 are fixedly mounted on the connecting frame 52. The second light source 42 is located at the shooting end of the second camera 41 to provide supplementary lighting for the second camera 41. The first camera 31 and the second camera 41 transmit image information of the crucible surface to an IoT terminal. Staff access the IoT terminal to obtain image information of the quartz crucible surface and observe whether there are defects on the surface of the quartz crucible.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
