Description

Technical Field

[0001] This application relates to the field of visual inspection, and in particular to a multi-angle adjustable positioning fixture for visual inspection. Background Technology

[0002] Visual inspection (also known as visual testing) is a technology that uses machines to replace human eyes for measurement and judgment. It analyzes product appearance defects or dimensional deviations through image processing systems and automatically filters out defective products. Machine vision systems typically include four key links: image acquisition, processing, feature extraction, and discrimination control. They are widely used in quality control in industrial production. A visual inspection machine is an industrial device that uses optical imaging, image processing, and artificial intelligence technology to automatically detect surface defects or quality problems in products. It captures product images through a high-resolution camera and combines algorithms to analyze appearance flaws (such as scratches, stains, deformations, etc.). It is widely used in industries such as electronics, textiles, food, and pharmaceuticals. It can replace manual quality inspection, significantly improve inspection efficiency and accuracy, and reduce the missed detection rate.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional visual inspection machines often require the use of positioning fixtures to fix the materials during use. However, conventional positioning fixtures are mostly in fixed positions, which can easily lead to blind spots when inspecting materials. Furthermore, moving the inspection equipment can cause it to shake during image capture, affecting the inspection results.

[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

[0010] Preferably, one end of the rotating rod is fixedly connected to a limiting plate, and one end of the limiting plate is movably mounted with a limiting frame. The dimensions of the limiting frame surface are adapted to the dimensions of one end of the limiting plate. The surface of the rotating plate is provided with a plurality of slots adapted to the limiting frame, and the inner wall of the slots is engaged with the surface of the limiting frame.

A rotating ball 5 is rotatably mounted on the inner wall of the support frame 4. A mounting disk 6 is fixedly connected to the top of the rotating ball 5. Several mounting slots are provided inside the mounting disk 6. The mounting slots facilitate fixing the workpiece to the surface of the mounting disk 6.

In conjunction with the rotation of the rotating disk 3 on the surface of the mounting frame 2, the mounting disk 6 can be rotated to different angle positions, which facilitates visual inspection of materials and effectively improves the inspection effect of visual inspection.

[0018] Reference Figure 2The bottom of the rotating ball 5 has several connecting grooves 7, and rotating gears 8 mesh inside the connecting grooves 7. A rotating rod 9 is fixedly installed inside the rotating gear 8. The rotating rod 9 controls the rotation of the rotating gear 8, thereby controlling the rotation of the rotating ball 5. By optimizing the transmission accuracy, the rotation error of the rotating rod 9 is effectively controlled. A first motor 10 is fixedly installed on the surface of the support frame 4. The output end of the first motor 10 is fixedly connected to one end of the rotating rod 9. After the first motor 10 is started, it controls the rotation of the rotating rod 9, thereby controlling the rotation of the rotating ball 5 to rotate left and right. A second motor 11 is fixedly installed at the bottom of the fixed frame 2. The output end of the second motor 11 is fixedly connected to the bottom of the rotating disk 3. After the second motor 11 is started, it controls the rotation of the rotating disk 3, thereby controlling the horizontal rotation of the rotating shaft, effectively reducing the amount of manual operation.

[0019] Reference Figure 3 - Figure 4 A limiting plate 12 is installed at one end of the rotating rod 9. A limiting frame 13 is engaged at one end of the limiting plate 12. The surface of the limiting frame 13 engages with the groove 14 on the surface of the rotating disk 3. By engaging the limiting frame 13 with the limiting plate 12 and the groove 14, the rotation angle of the rotating rod 9 and the rotating disk 3 is fixed, thereby fixing the angle of the fixed disk 6, effectively improving the accuracy of visual inspection. An electric push rod 16 is fixedly installed at one end of the limiting frame 13. One end of the electric push rod 16 is fixedly connected to the inside of the fixed frame 2.

The surface of the sliding frame 15 is slidably installed with the inner wall of the fixed frame 2. The sliding frame 15 restricts the movement of the limiting frame 13, thereby improving the stability of the movement of the limiting frame 13.

[0020] The implementation principle of a multi-angle adjustable positioning fixture for visual inspection according to an embodiment of this application is as follows: A base 1 is installed inside a visual inspection machine. A fixed frame 2 is fixedly connected to the inner wall of the base 1. A rotating disk 3 is rotatably mounted on the top of the fixed frame 2 via a bearing. A support frame 4 is fixedly connected to the top of the rotating disk 3. A rotating ball 5 is rotatably mounted on the inner wall of the support frame 4. A fixed disk 6 is fixedly connected to the top of the rotating ball 5. Several mounting slots are provided inside the fixed disk 6. These slots facilitate fixing the workpiece to the surface of the fixed disk 6, allowing the rotating ball 5 to rotate within the support frame 4, thus facilitating left and right rotation of the fixed disk 6. Combined with the rotation of the rotating disk 3 on the surface of the fixed frame 2, this allows the fixed disk 6 to be rotated to different angle positions, facilitating visual inspection of materials. Several connecting... The groove 7 is connected to a rotating gear 8, which is meshed inside the groove. A rotating rod 9 is fixedly installed inside the rotating gear 8, so that the rotating gear 8 can be rotated by the rotating rod 9, thereby controlling the rotation of the rotating ball 5. This effectively controls the rotation error of the rotating rod 9 by optimizing the transmission accuracy. A first motor 10 is fixedly installed on the surface of the support frame 4. The output end of the first motor 10 is fixedly connected to one end of the rotating rod 9, so that the rotating rod 9 can be rotated by the first motor 10 after it is started, thereby controlling the rotation of the rotating ball 5. A second motor 11 is fixedly installed at the bottom of the fixed frame 2. The output end of the second motor 11 is fixedly connected to the bottom of the rotating disk 3, so that the rotating disk 3 can be rotated by the second motor 11 after it is started, thereby controlling the horizontal rotation of the rotating shaft, effectively reducing the amount of manual operation.

[0021] A limiting plate 12 can also be installed at one end of the rotating rod 9. One end of the limiting plate 12 is engaged with a limiting frame 13. The surface of the limiting frame 13 engages with the slot 14 on the surface of the rotating disk 3. This allows the limiting frame 13 to engage with the limiting plate 12 and the slot 14, thereby fixing the rotation angle of the rotating rod 9 and the rotating disk 3, and thus fixing the angle of the fixed disk 6. This effectively improves the accuracy of visual inspection. An electric push rod 16 is fixedly installed at one end of the limiting frame 13. One end of the electric push rod 16 is fixedly connected to the inside of the fixed frame 2. This allows the limiting frame 13 to move by adjusting its length, thereby reducing manual operation. A sliding frame 15 is fixedly connected to one end of the limiting frame 13. The surface of the sliding frame 15 is slidably installed against the inner wall of the fixed frame 2. This allows the sliding frame 15 to restrict the movement of the limiting frame 13, thereby improving the stability of the movement of the limiting frame 13.
