Description

Technical Field

[0001] The utility model relates to the technical field of visual defect detection, in particular to a workpiece AI visual defect detection mechanism. Background Art

[0002] Visual defect detection is a method that uses computer vision technology and artificial intelligence algorithms to automatically detect and identify defects or anomalies in products or materials. Visual defect detection has many advantages, such as being contactless, damage-free, safe and reliable, having a wide spectral response range, being able to work for a long time in harsh environments, and having high production efficiency. It is widely used in various workpiece production fields.

[0003] The prior art discloses patent application number "CN202122215248.8", which is a visual inspection mechanism for workpiece processing, including a mounting frame. The visual inspection mechanism utilizes the mutual cooperation between the lifting equipment and the pallet to ensure the accuracy of the device's detection results, avoiding the problem that because the detection mechanism itself does not have a lifting function, once the height of the workpiece is far lower than the height of the detection mechanism, it will cause errors in the detection results, thereby reducing the practicality of the device.

[0004] This visual inspection mechanism can only improve the accuracy of the detection results by adjusting its height. However, in actual use, since the detection angle and range of most AI visual defect detection mechanisms are fixed, it is impossible to fully perform defect detection on the outside of the workpiece, resulting in poor detection effect of the AI visual defect detection mechanism, which affects the detection accuracy of the AI visual defect detection mechanism and is inconvenient to use.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, a workpiece AI visual defect detection mechanism includes a U-shaped base plate 1, the inner side of the U-shaped base plate 1 is rotatably connected to a threaded rotating rod 2, the outer surface of the threaded rotating rod 2 is threadedly connected to a connecting block 3, a first electric push rod 5 is installed on the lower side of the connecting block 3, an L-shaped plate 6 is fixedly connected to the lower side of the first electric push rod 5, and a limiting vertical plate 4 is installed on the lower side of the connecting block 3. The limiting vertical plate 4 is used to limit the movement of the L-shaped plate 6, so that as the first electric push rod 5 extends or shortens, the L-shaped plate 6 can be stably and reliably raised and lowered to facilitate the detection work;

[0027] The internal rotation of the L-shaped plate 6 is connected to a movable rotating plate 7, and the front side of the movable rotating plate 7 is slidingly connected to a card block 10. An AI vision camera 11 is fixed on the lower side of the card block 10. The AI vision camera 11 is based on image processing and machine learning technology. First, the image of the workpiece is acquired through image acquisition, and the image is pre-processed using an image processing algorithm. Next, based on the machine learning algorithm, the system will train a model that can learn the characteristics of the workpiece and identify anomalies or defects that are inconsistent with normal conditions, thereby realizing defect detection of the workpiece. A top seat 12 is fixedly installed on the upper side of the U-shaped bottom plate 1, and two smooth rods 9 are connected to the inside of the U-shaped bottom plate 1. Through the setting of the smooth rod 9, the two smooth rods 9 can limit the moving trajectory of the connecting block 3, so that the connecting block 3 can drive the AI vision camera 11 to move and adjust in order to adjust the appropriate detection position.

[0028] The L-shaped plate 6 is internally rotatably connected to a first movable block 13 , the movable rotating plate 7 is internally rotatably connected to a second movable block 14 , and a second electric push rod 15 is installed between the first movable block 13 and the second movable block 14 .

[0029] Two connecting plates 16 are fixedly connected to the lower side of the movable rotating plate 7. The inner sides of the two connecting plates 16 are installed with rubber strips 17. The rubber strips 17 are used to fix the card block 10. The upper side of the movable rotating plate 7 is clamped with a positioning plate 18. The lower side of the positioning plate 18 passes through the movable rotating plate 7 and extends to the interior of the movable rotating plate 7. The positioning plate 18 is used to fix the card block 10.

[0030] Two fixed round rods 19 are fixedly installed inside the top seat 12 . Two sliding frames 20 are slidably engaged with the outer surfaces of the two fixed round rods 19 , respectively. The sliding frames 20 are located inside the top seat 12 .

[0031] A mounting seat 21 is installed on the lower side of the two sliding frames 20, and two fastening bolts 22 are threadedly connected to the upper side of the two sliding frames 20. Through the setting of the fastening bolts 22, the two sliding frames 20 can be squeezed and fixed by using the fastening bolts 22, so that the adjusted sliding frames 20 can be used stably and reliably, which makes it convenient to fix the AI visual defect detection mechanism and is easy to use. The fastening bolts 22 are used to fix the sliding frames 20.

[0032] The left side of the threaded rotating rod 2 passes through the U-shaped bottom plate 1 and extends to the left side of the U-shaped bottom plate 1. The left side of the threaded rotating rod 2 is fixedly connected to the servo motor 8 through the motor mounting plate.

[0033] The working principle of the workpiece AI visual defect detection mechanism provided by this utility model is as follows:

[0034] By allowing the output shaft of the servo motor 8 to drive the threaded rotating rod 2 to rotate, the connecting block 3 on the threaded rotating rod 2 can be adjusted back and forth, so that the detection position of the AI vision camera 11 below can be adjusted, so that the AI vision camera 11 can adapt to workpieces in different positions, ensuring the flexibility of the visual defect detection mechanism. Then the first electric push rod 5 can also drive the AI vision camera 11 to move up and down to adjust the detection height, which is beneficial to improving the detection effect of the visual defect detection mechanism. Then, when the second electric push rod 15 slowly extends, the second electric push rod 15 will drive the second movable block 14 to rotate and the movable rotating plate 7 to rotate downward, so that the AI vision camera 11 is in a tilted state and performs a comprehensive inspection of the left side of the workpiece. Conversely, when the second electric push rod 15 slowly contracts, it will drive the movable rotating plate 7 to rotate upward, so that the AI vision camera 11 can perform a comprehensive inspection of the right side of the workpiece, thereby improving the detection accuracy and effect of the AI visual defect detection mechanism and ensuring the quality of production;

[0035] By snapping the card block 10 to the front of the movable turntable 7, the card block 10 will drive the AI vision camera 11 to be initially fixed at the lower position of the movable turntable 7. As the card block 10 is installed, the rubber strips 17 at the two card blocks 10 will squeeze and position the card block 10 to ensure the stability of the AI vision camera 11. Then, the positioning plate 18 is inserted into the interior of the movable turntable 7 to facilitate the assembly of the entire AI vision camera 11 by snapping. This makes it easy to load and unload the AI vision camera 11, making the AI visual defect detection mechanism more convenient to use. Then, the two sliding frames 20 at the two fixed round rods 19 are adjusted so that the sliding frames 20 and the mounting seat 21 can be adjusted to a suitable installation position, so that the entire workpiece AI visual defect detection mechanism can be flexibly fixed to improve the adaptability of the detection mechanism.
