Description

Technical Field

[0001] The present invention relates to the technical field of metal detection, and specifically to a metal surface vision detector based on artificial intelligence control. Background Art

[0002] In modern manufacturing, the quality of metal products directly affects the performance and safety of products. Precise detection of metal surface defects is crucial. Traditional metal surface defect detection mainly relies on manual visual inspection. This method has problems such as low efficiency, strong subjectivity, and a large impact of the experience and state of inspectors on detection accuracy, making it difficult to meet the requirements of large-scale industrial production. To improve the detection effect, a surface vision detector is needed.

[0003] There are still certain deficiencies in the existing surface vision detectors. When performing surface vision detection on an object, due to external interference, certain deviations may occur during the detection process, resulting in inefficient detection of the material during later use. To solve the above problems, reference can be made to a visual detection general platform disclosed in the prior art (Chinese Patent with application number CN202320260265.X and application date February 20, 2023). This platform can ensure the stable movement of the X-axis moving plate and the Z-axis moving along the X-axis direction through the X-axis linear motor and the X-axis linear guide rail. Specifically, the X-axis linear motor can also more conveniently adjust the moving speed to suit the different detection needs of different products, thereby facilitating the efficient detection of objects. Subsequently, reference can be made to a visual detection device for reducing the misjudgment rate of visual detection disclosed in the prior art (Chinese Patent with application number CN202322938143.4 and application date October 31, 2023). The visual detection device for reducing the misjudgment rate of visual detection includes a base in the control component. The user can adjust the distance between the shooting device and the fixed item through the control component, making the shooting device closer to the item, facilitating the user to take a clearer picture of the item through the shooting device and increasing the accuracy of the photo obtained by the user. Finally, reference can be made to a visual detection device disclosed in the prior art (Chinese Patent with application number CN202110065961.0 and application date January 18, 2021). Through the reasonable cooperation of the upper visual detection mechanism, the lower visual detection mechanism, the side visual detection mechanism, and the conveying mechanism, the overall detection of the product appearance is achieved, and the overall structure is simple and the detection efficiency is high.

[0004] Although the above device can achieve the purpose of efficiently detecting objects, there are still certain drawbacks in use. For the visual inspection scenario of small metal parts, changes in the external environment (especially light fluctuations) will significantly affect the detection efficiency. Specifically, sudden changes in ambient light intensity, specular reflection interference, or color temperature drift may cause highlights, overexposure, shadow occlusion, or color distortion during image acquisition, which in turn leads to deviations in feature extraction and reduces the detection accuracy.

[0005] Therefore, we propose a visual inspection instrument for metal surfaces based on artificial intelligence control to solve the problems raised above. Summary of the Invention

Moreover, the movement of the closing frame can make the outer wall of the closing frame slide inside the jacking groove, enabling the two rearview mirrors to move relatively, and thus it is convenient to fully illuminate and detect the brightness of the surface of the small metal part, improving the detection efficiency of the shooting detector.

[0018] 1.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-9 , the present invention provides the following technical solutions: A metal surface vision detector based on artificial intelligence control.

[0024] Embodiment 1: In order to facilitate the movement of small metal parts of different sizes and facilitate subsequent detection and processing, reference can be made to the attached Figure 1 - attached Figure 3 、attached Figure 5 and attached Figure 6, including a detection box 1 and a control panel 2 fixed at the position of the right side wall of the detection box 1. There is a movably positioned shooting detector 3 above the interior of the detection box 1, and an independent illuminator 20 is rotatably arranged at the position of the inner side wall of the detection box 1; an electric push rod 4 is fixed at the top of the detection box 1, and the output end of the electric push rod 4 is fixed to one side of a closing frame 5. Embedding rods 6 are slidably arranged at the four corner positions of the closing frame 5. One end of each embedding rod 6 close to the detection box 1 corresponds to one side of an embedding groove 7 opened inside the detection box 1. The movement of the embedding rods 6 inside the embedding groove 7 realizes the operation of the gas transmission mechanism. And a jacking groove 8 is opened at the left side position of the embedding groove 7, and the inner wall size of the jacking groove 8 fits the outer wall size of the closing frame 5; the gas transmission mechanism includes a docking rod 9 slidably arranged inside the detection box 1, and the right end position of the docking rod 9 is fixed to the side wall of an elastic oil bag 10. The other side of the elastic oil bag 10 is attached to the inner wall of the detection box 1. One end of the elastic oil bag 10 is connected to a fixed pipe 12 through a gas transmission hose 11, and the upper end position of the elastic oil bag 10 is also connected to a matching oil bag 19 through a hose. The outside of the matching oil bag 19 is adhered to the inside of the detection box 1. The bottom position of the independent illuminator 20 is rotatably arranged inside the detection box 1, and a torsion spring is also arranged at the rotation connection position between the independent illuminator 20 and the detection box 1; a two-way pressure valve is arranged at the connection position between the elastic oil bag 10 and the matching oil bag 19 through a hose. The outer end position of the gas transmission hose 11 is arranged at a limiting mechanism, and an electromagnetic lock is also arranged at the top position of the docking rod. The output end of the electromagnetic lock acts on the top surface position of the docking rod to achieve the purpose of locking and engaging a limiting rod through energization; the limiting mechanism includes a fixed pipe 12 fixedly connected to the end of the gas transmission hose 11. A fitting 14 is slidably arranged inside the left end of the fixed pipe 12. A moving pipe 16 is also fixed at the bottom position of the fixed pipe 12. The bottom of the moving pipe 16 is slidably arranged inside a vertical pipe 15. In addition, the bottom position of the vertical pipe 15 is fixed inside the detection box 1. A matching limiting member 18 is also arranged opposite to the fitting 14, and the bottom position of the matching limiting member 18 is fixed inside the detection box 1.

[0025] First, check the device during use to ensure that the entire device can operate normally. Place a small metal part on the workbench inside the detection box 1, ensuring that the small metal part, the cooperating limiting part 18, and the fitting part 14 are at the same horizontal line position. Subsequently, control the electric push rod 4 to work through the control panel 2, so that the closing frame 5 rolls on the ground through the moving rollers 501. The embedding rods 6 provided at the four corners of the closing frame 5 will be embedded into the embedding grooves 7. At this time, one end of the embedding rod 6 will squeeze the docking rod 9 inside the embedding groove 7, causing one end of the docking rod 9 to squeeze one side of the elastic oil bladder 10. As a result, the elastic oil bladder 10 can be squeezed against the inner wall of the detection box 1. At this time, the oil in the elastic oil bladder 10 will be transported through the air delivery hose 11. Since the outer end of the fixed pipe 12 is connected to the inside of the fixed pipe 12, continuous air delivery can cause the fitting part 14 to be pushed by the first return spring 13. The end of the fitting part 14 fits against the side of the small metal part. At this time, different small metal parts can be limited by the cooperating limiting part 18 and the fitting part 14.

[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that this embodiment can lift and turn over the small metal part after limiting, which is convenient for the surface defect detection of multiple ranges by the photographable detector 3. Refer to the attached Figure 5 and the attached Figure 6 , the right end inside the fixed pipe 12 is connected to the end of the fitting part 14 through the first return spring 13. The fitting part 14 is composed of a screw rod 1401, a fitting block 1402, and a cooperating spring 1403. The outer end of the fitting block 1402 slides on the outside of the fixed pipe 12, and the right end of the fitting block 1402 is helically connected to the screw rod 1401. The screw rod 1401 is connected to the inner end of the fitting block 1402 through the cooperating spring 1403; the fitting block 1402 forms a rotating structure with the inside of the fixed pipe 12 through the screw rod 1401, and the elastic force of the cooperating spring 1403 is greater than the elastic force of the first return spring 13. The outer side of the right end of the screw rod 1401 is attached to the inner wall of the fixed pipe 12 through a piston disk; the outer side of the bottom of the moving pipe 16 is attached to the inner wall of the vertical pipe 15 through a piston block, and an electromagnetic control two-way nozzle is provided at the bottom of the piston block. In addition, the bottom of the moving pipe 16 is connected to the inside of the vertical pipe 15 through a second return spring 17. A two-way pressure valve is provided between the second return spring 17 and the elastic oil bladder 10, and the elastic force of the two-way pressure valve is greater than the acting force of the entire limiting mechanism. The friction force between the screw rod 1401 and the fitting block 1402 is greater than the elastic force of the electromagnetic control two-way nozzle.

[0027] After the small metal part is limited, the oil in the elastic oil bladder 10 will continue to be transported. At this time, since the spiral rod 1401 is spirally connected to the inner side of the fitting block 1402, and the friction between the spiral rod 1401 and the fitting part 14 is greater than the elastic force of the electromagnetic control two-way nozzle, the oil will be transported between the vertical pipe 15 and the moving pipe 16. As a result, the moving pipe 16 releases the oil through the electromagnetic control two-way nozzle, causing the height of the moving pipe 16 to be adjusted inside the vertical pipe 15. When the moving pipe 16 moves to the maximum position, it will act on one side of the spiral rod 1401 at this time, so that the spiral rod 1401 can be pushed inside the fitting block 1402, and then the fitting block 1402 can drive the small metal part to turn over inside the fixed pipe 12, which is convenient for detecting the small metal part at different positions.

[0028] Embodiment 3: To solve the problem that in the visual inspection scenario of small metal parts by the current visual inspection instrument on the market, changes in the external environment, especially light fluctuations, will significantly affect the inspection efficiency. Specifically, sudden changes in ambient light intensity, specular reflection interference, or color temperature drift may cause high-light overexposure, shadow occlusion, or color distortion during image acquisition, resulting in deviation in feature extraction and reduced inspection accuracy. Reference can be made to Appendix Figure 1 - Appendix Figure 4 and Appendix Figure 7 - Appendix Figure 9 , a horizontal plate 21 is further provided at the left outer wall position of the closing frame 5, and the left outer end of the embedding rod 6 is fixedly connected to the horizontal plate 21. The inner side of the horizontal plate 21 is connected to the inner wall of the closing frame 5 through a plurality of sets of connecting springs 22. A rack plate 23 is fixed at the center position of the inner side of the horizontal plate 21. The outer side of the rack plate 23 slides inside the closing frame 5. One end of the rack plate 23 arranged inside the closing frame 5 is meshed with the outer side of the connecting gear 24. The center position of the connecting gear 24 is fixed at the side end position of the reflector 25; two groups of reflectors 25 are symmetrically distributed about the vertical center line of the closing frame 5, and the reflectors 25, the connecting gear 24, and the rack plate 23 are all inclined downward; a plurality of sets of teeth are fixed at the front and rear positions of the rack plate 23, and the outer sides of the teeth are meshed with the outer side of the connecting gear 24. The rotation range of the reflector 25 is 0 degrees - 40 degrees, and the elastic force of the connecting spring 22 is greater than the elastic force of the elastic oil bladder 10.

[0029] When the light source intensity needs to be adjusted, first, after the small metal part is limited, the top position of the docking rod 9 can be constrained by the locking bolt at this time. At this time, the embedding rod 6 will not move when pushing the docking rod 9. Subsequently, the electric push rod 4 continues to drive the closing frame 5 to move, and then the closing frame 5 will continue to slide inside the jacking groove 8. At this time, it can be realized that the embedding rod 6 will also slide at the four corner positions around the closing frame 5, and the connecting spring 22 is deformed by driving the cross plate 21. Since the rack plate 23 is inclined, the rack plate 23 will also slide inside the closing frame 5 at this time. At this time, the rack plate 23 drives the connecting gears 24 engaged and connected at the left and right positions to rotate, and then the connecting gears 24 can drive the reflecting mirror 25 to rotate relatively, so that the angle of the reflecting mirror 25 can be changed, thereby ensuring sufficient light source for the small metal part. In addition, since the closing frame 5 and the detection box 1 are in a closed state, it can be ensured that it is in a dark room. In addition, the independent illuminator 20 provides a light source, which is convenient for detecting the surface defects of the small metal part.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
