Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing device for the coating on the inner wall of a quartz crucible. Background Technology

[0002] During the production process, cracks and bubbles may appear in the coating of the inner wall of a quartz crucible. These can cause various problems during use, especially at high temperatures. Areas with cracks and bubbles may develop larger cracks or even break due to prolonged use at high temperatures. Therefore, the inner wall coating of a quartz crucible needs to be inspected after production.

[0003] The prior art, as disclosed in Chinese Patent Publication No. CN219142680U, is a quartz crucible inspection device based on machine vision, belonging to the field of photovoltaic Czochralski single-crystal silicon technology. It mainly includes a base, a rotating platform, a quartz crucible, a support, a crossbeam, a CCD camera, and an industrial control computer. The rotating platform is installed in the center of the base, and the quartz crucible is stably placed on the rotating platform. A support perpendicular to the main plane of the base is located at the edge of the base, and a sliding component is installed on the support. The crossbeam is installed on the support via an arc-shaped shackle, the CCD camera is mounted on the crossbeam, and the industrial control computer is installed at the edge of the base. This invention directly replaces manual visual inspection; the inspector only needs to operate the industrial control computer to complete the inspection.

[0004] However, most existing quartz crucible testing devices generally use a rotating platform to rotate the quartz crucible and then take pictures with a CCD camera to inspect the inner wall of the quartz crucible. However, they lack a clamping and centering device. Therefore, during use, the quartz crucible may be thrown away by the rotational force of the rotating platform, causing equipment damage and personnel injury. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a quartz crucible inner wall coating inspection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a quartz crucible inner wall coating inspection device, including a workbench and a crucible body disposed on the workbench. Two clamping assemblies are disposed opposite each other on the workbench for clamping the crucible body. A driving assembly for moving the clamping assemblies is disposed on the lower side of the workbench. An adjusting assembly for adjusting the height of the clamping assemblies is disposed between the driving assembly and the two clamping assemblies. A detection assembly is disposed on one side of the workbench.

[0008] Furthermore, the adjustment component includes a slider, a groove is provided on the worktable, the slider is slidably connected in the groove, a sleeve is fixedly connected to the upper end of the slider, a support rod is slidably connected inside the sleeve, a first motor is fixedly connected inside the sleeve, a threaded rod is fixedly connected to the shaft end of the first motor, and the threaded rod is threadedly connected to the support rod.

[0009] Furthermore, the clamping assembly includes a housing fixedly connected to the upper end of the support rod, a rack slidably connected inside the housing, gears rotatably connected to both sides of the rack, both gears meshing with the rack, a plate fixedly connected to the circumference of the gears, a wheel rotatably connected to both the plate and the front end of the rack, a connecting plate fixedly connected to the other end of the rack, and a tension spring fixedly connected between the connecting plate and the housing.

[0010] Furthermore, the drive assembly includes a cylinder fixedly connected to the lower side of the worktable, with connecting rods rotatably connected to both sides of the cylinder's telescopic end, and a slider pinned to the free end of each connecting rod.

[0011] Furthermore, the detection component includes a U-shaped frame fixedly connected to the worktable and a sliding plate slidably connected between the two ends of the U-shaped frame. A screw is rotatably connected between the U-shaped frame and the worktable. The sliding plate is threadedly connected to the screw. A third motor is fixedly connected to the upper end of the U-shaped frame. One end of the screw passes through the U-shaped frame and is fixedly connected to the shaft end of the third motor. A vision unit is fixedly connected to one side of the sliding plate.

[0012] Furthermore, a rotating shaft is rotatably connected to the upper center of the worktable, and a disk is fixedly connected to the shaft end of the rotating shaft. The disk is rotatably connected to the worktable, and the crucible body is disposed at the upper end of the disk.

[0013] The present invention provides a quartz crucible inner wall coating inspection device, which has the following advantages: The present invention fixes the quartz crucible through a clamping assembly and achieves adaptive clamping through a gear and rack linkage mechanism.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 A quartz crucible inner wall coating inspection device includes a workbench 1 and a crucible body 11 disposed on the workbench 1. Two clamping components 2 are disposed opposite to each other on the workbench 1 for clamping the crucible body 11. A driving component 3 is disposed on the lower side of the workbench 1 for driving the clamping components 2 to move. An adjusting component 5 for adjusting the height of the clamping components 2 is disposed between the driving component 3 and the two clamping components 2. A detection component 4 is disposed on one side of the workbench 1.

[0022] It should be noted that the adjustment component 5 includes a slider 51, and a groove 12 is provided on the worktable 1. The slider 51 is slidably connected in the groove 12. A sleeve 52 is fixedly connected to the upper end of the slider 51. A support rod 55 is slidably connected in the sleeve 52. A first motor 53 is fixedly connected in the sleeve 52. A threaded rod 54 is fixedly connected to the shaft end of the first motor 53. The threaded rod 54 is threadedly connected to the support rod 55. Both the sleeve 52 and the support rod 55 are rectangular. The rotation of the first motor 53 causes the threaded rod 54 to rotate, and the rotation of the threaded rod 54 causes the support rod 55 to move. The support rod 55 causes the clamping component 2 to move up and down, thereby bringing the clamping component 2 closer to the center of gravity of the crucible body 11 of different sizes, increasing the stability of the clamping.

[0023] In this embodiment, the clamping assembly 2 includes a housing 21 fixedly connected to the upper end of the support rod 55. A rack 22 is slidably connected inside the housing 21. Gears 23 are rotatably connected to both sides of the rack 22, and both gears 23 mesh with the rack 22. Plates 24 are fixedly connected to the circumference of the gears 23. Wheels 25 are rotatably connected to the front end of the plates 24 and the rack 22. A connecting plate 26 is fixedly connected to the other end of the rack 22. A tension spring 27 is fixedly connected between the connecting plate 26 and the housing 21. When the rack 22 contacts the outer wall of the crucible body 11, the rack 22 is pressed and moves backward, driving the gears 23 to rotate, thereby driving the other two plates 24 to move synchronously. Finally, the six wheels 25 are evenly attached to the surface of the crucible body 11. After the test is completed, the slider 51 is reset. The rack 22 is reset by the tension spring 27 to facilitate the next clamping. When clamping the two racks 22, they respectively contact the crucible body 11. If the crucible body 11 is tilted, the racks 22 will extend differently when they contact the crucible body 11. When the racks 22 extend differently, the extension length of the tension spring 27 will also be different. The tension spring 27 with a longer extension will generate a greater tension, so that the rack 22 will no longer move in the position inside the outer shell 21. However, the two sliders 51 move synchronously through the cylinder 31, pushing the racks 22 inward. Thus, the longer extension length of the rack 22 centers the crucible body 11. After centering, the racks 22 continue to contact the crucible body 11, thus moving the other two plates 24 synchronously, so that the six wheels 25 are evenly attached to the surface of the crucible body 11.

[0024] Furthermore, the driving assembly 3 includes a cylinder 31 fixedly connected to the lower side of the workbench 1. Both sides of the telescopic end of the cylinder 31 are rotatably connected to connecting rods 32. The free end of each connecting rod 32 is pinned to a slider 51. By retracting the telescopic end of the cylinder 31, the two sliders 51 are moved synchronously towards the center through the connecting rods 32. When the sliders 51 move, they will move the clamping assembly 2 to clamp the crucible body 11.

[0025] Furthermore, the detection component 4 includes a U-shaped frame 41 fixedly connected to the workbench 1 and a sliding plate 42 slidably connected between the two ends of the U-shaped frame 41. A screw 43 is rotatably connected between the U-shaped frame 41 and the workbench 1. The sliding plate 42 is threadedly connected to the screw 43. A third motor 44 is fixedly connected to the upper end of the U-shaped frame 41. One end of the screw 43 passes through the U-shaped frame 41 and is fixedly connected to the shaft end of the third motor 44. A vision unit 45 is fixedly connected to one side of the sliding plate 42. The third motor 44 drives the threaded rod to rotate, thereby moving the sliding plate 42 up and down and moving the vision unit 45. The vision unit 45 consists of a vision detection module, a gimbal, and an illumination lamp, which is existing technology and will not be described in detail here. The vision module detects and observes bubbles and cracks in the coating, and the gimbal rotates the vision module and the illumination lamp by an angle.

[0026] Based on the above embodiment, a rotating shaft 13 is rotatably connected to the upper center of the workbench 1, and a disc 14 is fixedly connected to the shaft end of the rotating shaft 13. The disc 14 is rotatably connected to the workbench 1, and a rubber anti-slip pad is provided on the disc 14 to prevent slipping. The crucible body 11 is located on the upper end of the disc 14. When the crucible body 11 is placed on the upper end of the disc 14, the operator will rotate the crucible body hollowly when the vision module detects a crack, and then use a marker to mark the crack for statistical purposes.

[0027] Working method: During operation, the crucible body 11 is placed on the upper end of the disc 14. Then, the adjustment component 5 is activated according to the size of the crucible body 11 to adjust the clamping component 2 to a suitable height. After that, the cylinder 31 is activated to push the clamping component 2 inward. When the six wheels 25 on the clamping component 2 are evenly attached to the surface of the crucible body 11, the third motor 44 is activated to rotate the crucible body 11 and lower the vision unit 45. When the vision unit 45 is lowered to a suitable position, the third motor 44 is stopped, and the vision unit 45 inspects the crucible body 11.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
