Description

Technical Field

[0001] This application relates to the field of inspection of sheet metal parts for washing machines, and in particular to a visual inspection system for sheet metal parts for washing machines. Background Technology

[0002] Sheet metal for washing machines refers to the thin metal sheet material used for the outer shell of washing machines. It is usually processed using cold working techniques. Specific applications of sheet metal for washing machines include components such as the outer shell and control panel. These components are made through processes such as stamping, cutting, bending, and welding to ensure the appearance and structural strength of the washing machine. Sheet metal for washing machines is often inspected using a vision inspection system. A vision inspection system is a system that uses machine vision technology to inspect products. It uses a combination of industrial cameras, lenses, and light sources to inspect the appearance, dimensions, defects, etc. of products. The vision inspection system can replace manual labor to complete tasks such as barcode characters, cracks, packaging, surface coating integrity, and dents, significantly improving the inspection speed and accuracy of the production line, while reducing labor costs and error rates. When using a conventional vision inspection system, after the inspection frame is installed stably, the material to be inspected is placed on the top of the inspection frame. The inner wall of the inspection frame is equipped with a base box, and the top of the base box is connected to the inspection mechanism. The inspection mechanism takes pictures of the material on the top of the inspection frame and transmits them to the computer for inspection.

[0003] Regarding the aforementioned technologies, the inventors believe that when using a visual inspection system, due to the varying sizes of the sheet metal parts in washing machines, the sheet metal parts may be too large or too small during inspection by the inspection agency. This can lead to situations where the distance between the inspection agency and the sheet metal parts is too close or too far, affecting the inspection effect of the inspection agency.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0023] This application discloses a visual inspection system for sheet metal parts of a washing machine, referring to... Figure 1 - Figure 2The system includes a detection frame 1. During use, after the detection frame 1 is stably installed, the material to be inspected is placed on top of the detection frame 1. A base box 3 is installed on the inner wall of the detection frame 1, and a detection mechanism 2 is connected to the top of the base box 3. The detection mechanism 2 photographs the material on top of the detection frame 1 and transmits the image to a computer for inspection. A mounting frame 4 is connected to the surface of the detection mechanism 2. Two connecting frames 5 are slidably connected to the inner wall of the mounting frame 4. A fixing frame 6 is welded to the bottom of the connecting frame 5. One end of the fixing frame 6 is welded to the surface of the detection frame 1. The connecting frames 5 facilitate the adjustment of the height of the detection mechanism 2 at one end of the mounting frame 4, allowing the detection mechanism 2 to be moved to a suitable height for inspecting sheet metal parts of different sizes, effectively improving the inspection effect of the visual inspection system.

[0024] Reference Figure 2 A motor 7 is installed on the inner wall of the fixed frame 6. A threaded rod 8 is installed at the output end of the motor 7. The surface of the threaded rod 8 is threadedly connected to the inner wall of the mounting frame 4. After the motor 7 is started, the threaded rod 8 is rotated to adjust the height of the mounting frame 4 on the surface of the threaded rod 8, thereby reducing the amount of manual operation. A support frame 9 is welded to the top of the detection frame 1. A laser detector 10 is installed at one end of the support frame 9. The laser detector 10 emits a laser beam. After the laser beam hits the sheet metal part, it bounces back. The laser detector 10 receives the returned beam and detects the height of the sheet metal part, which facilitates the operation of the motor 7. Several auxiliary plates 11 are installed on the top of the fixed frame 6. The auxiliary plates 11 reduce the collision force between the mounting frame 4 and the fixed frame 6 when the mounting frame 4 falls.

[0025] Reference Figure 3 - Figure 4 A connecting plate 12 is installed on the top of the threaded rod 8. Two limit brackets 13 are snapped onto the surface of the connecting plate 12. The limit brackets 13 are installed on the top of the connecting frame 5 by means of a sliding frame 14. The connection between the limit brackets 13 and the connecting plate 12 fixes the threaded rod 8, thereby fixing the mounting frame 4 at a suitable height. An electric push rod 15 is installed at one end of each of the two limit brackets 13. The bottom end of the electric push rod 15 is slidably connected to the surface of the sliding frame 14. The length of the electric push rod 15 can be adjusted to control the two limit brackets 13, making it more convenient to use. A slider 16 is installed at the bottom end of the electric push rod 15. A slide rail 17 is slidably connected to the surface of the slider 16. The bottom end of the slide rail 17 is connected to the top of the sliding frame 14. The slider 16 and the slide rail 17 limit the movement of the electric push rod 15, effectively improving the stability of the electric push rod 15 during use.

[0026] The implementation principle of the visual inspection system for sheet metal parts of a washing machine according to an embodiment of this application is as follows: A mounting frame 4 is connected to the surface of an inspection mechanism 2. Two connecting frames 5 are slidably connected to the inner wall of the mounting frame 4. A fixing frame 6 is welded to the bottom end of each connecting frame 5. One end of the fixing frame 6 is welded to the surface of the inspection frame 1, so that the height of the inspection mechanism 2 at one end of the mounting frame 4 can be easily adjusted using the connecting frames 5. This allows the inspection mechanism 2 to be moved to a suitable height for inspecting sheet metal parts of different sizes. A motor 7 is installed on the inner wall of the fixing frame 6. A threaded rod 8 is installed at the output end of the motor 7. The surface of the threaded rod 8 is threadedly connected to the inner wall of the mounting frame 4. The motor 7 is used to start and control the rotation of the threaded rod 8, and the height of the mounting bracket 4 on the surface of the threaded rod 8 can be adjusted, thereby reducing the amount of manual operation. The top of the detection frame 1 is welded with a support frame 9, and a laser detector 10 is installed at one end of the support frame 9. The laser detector 10 emits a laser beam, which bounces off the sheet metal part after contacting it. The laser detector 10 receives the returned beam and detects the height of the sheet metal part, thereby facilitating the control of the motor 7. Several auxiliary plates 11 are installed on the top of the fixed frame 6 to reduce the collision force between the mounting frame 4 and the fixed frame 6 when the mounting frame 4 falls.

[0027] A connecting plate 12 can also be installed on the top of the threaded rod 8. Two limit brackets 13 are snapped onto the surface of the connecting plate 12. The limit brackets 13 are installed on the top of the connecting frame 5 by means of a sliding frame 14, so that the limit brackets 13 and the connecting plate 12 can be snapped together to fix the threaded rod 8 and fix the mounting frame 4 at a suitable height. An electric push rod 15 is installed at one end of each of the two limit brackets 13. The bottom end of the electric push rod 15 is slidably connected to the surface of the sliding frame 14, so that the length of the electric push rod 15 can be adjusted to control the two limit brackets 13, making it more convenient to use. A slider 16 is installed at the bottom end of the electric push rod 15. A slide rail 17 is slidably connected to the surface of the slider 16. The bottom end of the slide rail 17 is connected to the top of the sliding frame 14, so that the movement position of the electric push rod 15 can be limited by the slider 16 and the slide rail 17, effectively improving the stability of the electric push rod 15 during use.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
