Description

Technical Field

[0001] This utility model relates to the field of diamond wire inspection technology, and in particular to a visual inspection device for diamond wire. Background Technology

[0002] Visual inspection of diamond wire is a method that uses machine vision technology to inspect the quality and analyze defects of diamond wire. It involves capturing images of the diamond wire with a camera, then using image processing algorithms to analyze and process the images to extract the characteristic information of the diamond wire, such as wire diameter, abrasive grain distribution, and surface defects. This information is then compared with preset standards to determine whether the diamond wire meets the quality requirements.

[0003] The illumination angle of the existing ring light source is not convenient to adjust. When the illumination angle of the ring light source deviates, it will cause inaccurate detection results. This problem needs to be solved.

[0004] The existing patent (publication number: CN208505844U) discloses a diamond wire particle detection device, which solves the problem that the illumination angle of the light source is inconvenient to adjust in the existing detection device. The arc-shaped through groove can adjust the relative position between the lamp and the first fixed plate. After loosening the first bolt and adjusting the lamp to have a suitable illumination angle, the first bolt can be tightened. It has the advantage of conveniently adjusting the illumination angle of the light source.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, while the lamps proposed in these patents are adjustable, there are only two lamps available, which makes it inconvenient to evenly illuminate the area around the diamond wire. Furthermore, the two cameras do not capture a comprehensive view of the diamond wire, affecting the accuracy of diamond wire particle detection.

[0006] Therefore, a visual inspection device for diamond wire is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a visual inspection device for diamond wire, which solves the problems in the existing patents that, although the lamps are adjustable, there are only two, which is inconvenient to evenly illuminate the diamond wire from all sides, and the two cameras do not capture a comprehensive view of the diamond wire, thus affecting the accuracy of diamond wire particle detection.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection device for diamond wire, comprising a base plate, a roller on the top of the base plate, a diamond wire body evenly wound on the surface of the roller, a guide roller on the top of the base plate, an illumination and shooting mechanism on the top of the base plate, contact mechanisms on both sides of the rear side of the illumination and shooting mechanism, and a slide rail on the top of the base plate.

[0009] The lighting and shooting mechanism includes several lighting LEDs, four wide-angle cameras, two mounting brackets, and a slip ring.

[0011] Preferably, support blocks are fixedly connected to both sides of the bottom of the slide rail, and the bottom of the support blocks is fixedly connected to the top of the base plate.

[0012] Preferably, support plates are fixedly connected to both sides of the top of the base plate, and the guide roller is rotatably connected between the two support plates on opposite sides, with the sanding line body in contact with the surface of the guide roller.

[0013] Preferably, the contact mechanism includes a contact block, a magnetic block, and a guide rail. The front side of the guide rail is fixedly connected to the rear side of the slip ring. The magnetic block is fixedly connected to the contact block on the side closest to it. The magnetic block is magnetically connected inside the guide rail. The front side of the abrasive wire body passes between the opposite sides of the two contact blocks and passes through the slip ring.

[0014] Preferably, a pull block is fixedly connected to the top of the contact block, and both the contact block and the guide roller are made of silicon carbide ceramic.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an illumination and shooting mechanism, with multiple illumination beads and four wide-angle cameras, which can follow the slip ring to capture a comprehensive and clear image of the sand wire body. Then, the image is analyzed and tested by an external image analysis system to determine whether the sand wire body is compliant.

[0019] 2.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A visual inspection device for diamond wire includes a base plate 1, a winding roller 5 is provided on the top of the base plate 1, a diamond wire body 6 is uniformly wound on the surface of the winding roller 5, a guide roller 4 is provided on the top of the base plate 1, an illumination and shooting mechanism 2 is provided on the top of the base plate 1, contact mechanisms 9 are provided on both sides of the rear side of the illumination and shooting mechanism 2, and a slide rail 14 is provided on the top of the base plate 1.

[0030] The lighting and shooting mechanism 2 includes several lighting beads 201, four wide-angle cameras 202, two fixing brackets 203 and a slip ring 204. The lighting beads 201 are fixedly connected to the surface of the slip ring 204. The side of the fixing bracket 203 near the slip ring 204 is fixedly connected to the slip ring 204. The side of the wide-angle camera 202 near the fixing bracket 203 is fixedly connected to the fixing bracket 203. The lighting beads 201 are tilted towards the side of the wide-angle camera 202.

[0031] In this embodiment: the abrasive thread body 6 is wound around the roller 5, and the limiting button 7 restricts the rotation of the roller 5 inside the slot 15. Then, the external receiving and winding device pulls the abrasive thread body 6, guides it through the guide roller 4, passes through the contact block 901 and the slip ring 204, and is then wound up by the external receiving and winding device to ensure stable conveying. In the lighting and shooting mechanism 2, multiple lighting beads 201 tilted towards the wide-angle camera 202 are evenly distributed on the surface of the slip ring 204 to provide multi-angle illumination. The four wide-angle cameras 202 are connected to the slip ring 204 through the fixing bracket 203 to expand the shooting range. The two work together to improve the detection accuracy of the abrasive thread body 6. When the abrasive thread body 6 comes off from different positions of the roller 5 and contacts the contact block 901, the contact block 901 and the contact block 901... The magnetic connection of the rail 903 is fixed to the rear side of the slip ring 204. The movement of the abrasive wire body 6 will drive the contact block 901, thereby causing the slip ring 204 to move left and right under the cooperation of the slider 12 and the slide rail 14, realizing the synchronous movement of the lighting and shooting components, ensuring the matching of the detection position. The wide-angle camera 202 transmits the captured image to the external image analysis system. After processing and analysis, based on the standard to identify defects, etc., the detection result is output to determine whether the abrasive wire body 6 is qualified. This solves the problem in the existing patent that although the lamps can be adjusted, there are only two, which is inconvenient to uniformly illuminate the four sides of the abrasive wire. In addition, the two cameras do not capture the abrasive wire comprehensively enough, which affects the detection accuracy of the abrasive wire particles.

[0032] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, a slider 12 is fixedly connected to the bottom of the slip ring 204, and the slider 12 is slidably connected inside the slide rail 14.

[0033] Specifically, such as Figure 2 As shown, support blocks 11 are fixedly connected to both sides of the bottom of the slide rail 14, and the bottom of the support blocks 11 is fixedly connected to the top of the base plate 1.

[0034] Specifically, such as Figure 2 As shown, support plates 10 are fixedly connected to both sides of the top of the base plate 1, and guide roller 4 is rotatably connected between the opposite sides of the two support plates 10. The sanding body 6 is in contact with the surface of the guide roller 4.

[0035] In this embodiment: the slider 12 slides inside the slide rail 14, which allows the slip ring 204 to move left and right. The slide rail 14 is stably supported on the top of the base plate 1 by the support block 11, and is rotatably connected between the two support plates 10 on opposite sides by the guide roller 4. The guide roller 4 can rotate and support the sanding thread body 6, so that the sanding thread body 6 can be stably removed from the surface of the winding roller 5.

[0036] Specifically, such as Figure 4 As shown, the contact mechanism 9 includes a contact block 901, a magnetic block 902, and a rail 903. The front side of the rail 903 is fixedly connected to the rear side of the slip ring 204. The magnetic block 902 is fixedly connected to the contact block 901 on the side close to the contact block 901. The magnetic block 902 is magnetically connected to the inside of the rail 903. The front side of the sanding wire body 6 passes between the opposite sides of the two contact blocks 901 and passes through the slip ring 204.

[0037] Specifically, such as Figure 4 As shown, a pull block 13 is fixedly connected to the top of the contact block 901. Both the contact block 901 and the guide roller 4 are made of silicon carbide ceramic.

[0038] In this embodiment: the abrasive wire body 6 passes between the two opposite sides of the two contact blocks 901, then passes through the inside of the slip ring 204, and then connects the abrasive wire body 6 to the external receiving and winding equipment for winding. At this time, when the abrasive wire body 6 comes off from different positions on the surface of the winding roller 5, it will contact the contact block 901 and generate force. Therefore, the left and right movement of the abrasive wire body 6 will push the contact block 901 to move left and right, thereby causing the slip ring 204 to move along the slide rail 14 with the cooperation of the slider 12 and the slide rail 14, realizing the synchronous movement of multiple lighting beads 201 and four wide-angle cameras 202, ensuring that effective shooting can be obtained and detection can be performed when the abrasive wire body 6 is detected at different positions. The silicon carbide contact block 901 and guide roller 4 have strong wear resistance, which can improve the service life of the contact block 901 and guide roller 4. By pulling the hand pull block 13 upward, the magnetic block 902 can be disengaged from the rail 903, which makes it easy to replace the contact block 901.

[0039] Specifically, such as Figure 1 and Figure 5As shown, support plates 8 are fixedly connected to both sides of the top of the base plate 1. The support plate 8 has a slot 15 inside. The roller 5 is rotatably connected inside the slot 15. A limit button 7 is provided on the top of the support plate 8. The bottom of the limit button 7 passes through the support plate 8 and extends into the slot 15. The surface of the limit button 7 is threadedly connected to the inside of the support plate 8. The surface of the limit button 7 is in active contact with the surface of the roller 5.

[0040] Specifically, such as Figure 1 As shown, positioning holes 3 are provided at the four corners of the top of the base plate 1.

[0041] In this embodiment: by moving the roller 5 into the slot 15 and then connecting the limit button 7 to the internal thread of the support plate 8, the roller 5 can be limited, facilitating its rotation and allowing the abrasive thread body 6 on the surface of the roller 5 to be easily removed. Furthermore, there is a certain frictional resistance between the roller 5 and the slot 15, preventing the abrasive thread body 6 from being removed from the surface of the roller 5 too quickly when the external receiving and winding equipment rewinds it. The positioning hole 3 at the top of the base plate 1 can be fixed to the top of the external stable workbench using external bolts for ease of use.

[0042] Working principle: The abrasive thread body 6 is wound around the surface of the winding roller 5. The winding roller 5 is rotatably connected to the groove 15 inside the support plate 8. By screwing the limit button 7 into the groove 15, it abuts against the surface of the winding roller 5, which can limit the rotation of the winding roller 5 and prevent the winding roller 5 from accidentally loosening. By using an external receiving winding device connected to the abrasive thread body 6, the winding power is provided, pulling the abrasive thread body 6 out of the winding roller 5. It is guided by the guide roller 4, passes between the two contact blocks 901, and then passes through the slip ring 204. Finally, it enters the external receiving winding device for winding, ensuring the stability of the abrasive thread conveying path. In the imaging mechanism 2, multiple illumination beads 201 are tilted towards the wide-angle camera 202 and evenly distributed on the surface of the slip ring 204, providing multi-angle, blind-spot-free illumination for the sanding wire body 6 and avoiding shadow interference. The four wide-angle cameras 202 are connected to the slip ring 204 through the fixing bracket 203. Their wide-angle characteristics expand the shooting range and can capture images of the surface of the sanding wire body 6 from all directions. The two work together to greatly improve the particle detection accuracy on the surface of the sanding wire body 6. When the sanding wire body 6 comes off from different positions on the surface of the roller 5, it will contact the contact block 901. The contact block 901 is magnetically connected to the rail 903 via the magnetic block 902. The rail 903 is fixed to the rear side of the slip ring 204. Therefore, the left and right movement of the sanding wire body 6 will push the contact block 901 to move left and right, thereby causing the slip ring 204 to move along the rail 14 in cooperation with the slider 12. This achieves the synchronous movement of multiple lighting beads 201 and four wide-angle cameras 202, ensuring that the lighting and shooting mechanisms are always in the appropriate position when detecting at different positions of the sanding wire body 6. The wide-angle cameras 202 will capture the sanding wire body 6. The image of the wire body 6 is transmitted to an external image analysis system. The external image analysis system processes and analyzes the image, and identifies defects, wear, and sand particle distribution on the surface of the wire body 6 according to preset detection standards. Finally, it outputs the detection results to determine whether the wire body 6 is qualified. This solves the problem in the existing patent that although the lamps can be adjusted, there are only two, which is inconvenient to evenly illuminate the four sides of the diamond wire. In addition, the two cameras do not capture the diamond wire comprehensively enough, which affects the accuracy of the detection of diamond wire particles.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
