[0002] Surfing is an extreme sport powered by waves. Surfers stand on surfboards and use the propulsion of waves to glide. Surfers control the surfboards and move forward against the waves, experiencing the collision of speed and passion. Initially, surfers did not use tail fins, but controlled the direction of the surfboard by moving their bodies and changing their postures. However, this method is inefficient and requires high skills from surfers. The tail fin plays a vital role in the surfboard. It can not only help surfers better control the direction of the surfboard, but also improve the stability and safety of surfing. Therefore, the use of surfboard tail fins is becoming more and more widespread. The use of surfboard tail fins can guide water flow, improve controllability, increase speed and other advantages. In order to ensure the good performance of the surfboard tail fin, after the surfboard tail fin is generated, its surface needs to be inspected to avoid defects such as cracks, dents, wear and tear that affect the performance of the surfboard tail fin.

The tail fin of the surfboard is scanned by the 3D vision camera 9, and after multiple scans, the images after multiple scans are compared to analyze the defects on the surface. Compared with the use of traditional infrared and laser, it has more accurate detection results.

[0024] The control component includes a linkage shaft 13 and a follower shaft 16. The linkage shaft 13 and the follower shaft 16 are rotatably connected to the top wall of the chassis 7 through bearings. The linkage shaft 13 passes through and is fixedly connected with a friction wheel 14 and a second gear 15. The friction wheel 14 passes through the chassis 7 and the detection chamber 8 and extends into the detection chamber 8 (such as Figure 6 and Fig. 9As shown in the figure, the friction wheel 14 is made of rubber, and its side wall is provided with dotted protrusions, so that after the friction wheel 14 abuts against the placement seat 6, the friction wheel 14 is driven to rotate by friction force under the rotation of the placement seat 6, and the wheel diameter of the friction wheel 14 is consistent with the wheel diameter of the placement seat 6. The follower shaft 16 penetrates and is fixedly connected with the third gear 17, and the second gear 15 is meshed with the third gear 17. The number of teeth of the second gear 15 is half of the number of teeth of the third gear 17, so that when the second gear 15 rotates two times, it drives the third gear 17 to rotate one time, and the first gear 302 is an incomplete gear (such as Figure 8 As shown), the number of teeth is twice that of the second gear 15, so that when the first gear 302 rotates one circle, it meshes with the second gear 15 and drives it to rotate two circles. The side wall of the follower shaft 16 is fixedly connected to the movable electric block 22 through an insulating rod, and the inner side wall of the chassis 7 away from the second gear 15 is fixedly connected to the insulating ring 18, and the inner side wall of the insulating ring 18 is fixedly connected to the first electric ring 19, the second electric ring 20, and the third electric ring 21. The first electric ring 19, the second electric ring 20, and the third electric ring 21 are arranged as shown in Fig. 9As shown, during the process of the movable electric block 22 rotating one circle, it experiences: contacting with the first electric ring 19 alone - contacting with the first electric ring 19 and the second electric ring 20 at the same time - contacting with the second electric ring 20 alone - contacting with the second electric ring 20 and the third electric ring 21 at the same time, so that a single lamp bead 10 is illuminated or two lamp beads 10 are combined to emit light, providing four different colors of light sources for supplementary lighting, the first electric ring 19, the second electric ring 20, and the third electric ring 21 are respectively electrically connected to the corresponding lamp bead 10 through wires, and the first electric ring 19, the second electric ring 20 and the third electric ring 21 are connected to the corresponding lamp beads 10 respectively, and then connected to the negative pole of the power supply, and the movable electric block 22 is connected to the positive pole of the power supply. After the movable electric block 22 contacts the first electric ring 19, the second electric ring 20, and the third electric ring 21, the corresponding lamp beads 10 can be lit. When the placement seat 6 rotates, the friction wheel 14 is also driven to rotate by friction. The friction wheel 14 drives the second gear 15 to rotate through the linkage shaft 13, and the second gear 15 drives the third gear 17 meshing with it to rotate. The third gear 17 drives the movable electric block 22 to rotate through the follower shaft 16. During the first 180° rotation of the placement seat 6, the movable electric block 22 contacts the first electric ring 19, and the top lamp bead 10 lights up, emitting red light, and the red light is used for fill light scanning. During the second 180° rotation of the placement seat 6, the movable electric block 22 contacts the first electric ring 19 and the second electric ring 20 at the same time, and the top and middle lamp beads 10 light up, and the red light and green light are combined into yellow light for fill light scanning. The placement seat 6 rotates During the third 180° process, the active electric block 22 contacts the second electric ring 20 alone, and the middle lamp bead 10 lights up, emitting green light, and fill-in light scanning is performed by the green light. When the placement seat 6 rotates a fourth 180°, it contacts the second electric ring 20 and the third electric ring 21 at the same time, and the middle and bottom lamp beads 10 light up, and purple light is synthesized by green light and blue light to perform fill-in light scanning. Four scans are performed through four colors of fill light, which makes it easier to find the existence of defects during comparative analysis, further improving the accuracy of the detection results.

[0025] The driving component also includes a fixed plate 24, which is fixedly connected to the mounting shaft 5 through a penetration, and a plurality of convex ridges 25 are fixedly connected to the side wall of the mounting shaft 5. Through the arrangement of the convex ridges 25, the fourth gear 26 can slide up and down along the mounting shaft 5 while driving the mounting shaft 5 to rotate. The convex ridges 25 are slidably connected to the fourth gear 26, and a plurality of first springs 27 are fixedly connected between the fourth gear 26 and the fixed plate 24.

[0026] The pop-up component includes a sliding groove 31, and the cross section of the sliding groove 31 is a cross star (such as Fig.10As shown in the figure), the limiting block 105 of the side wall of the tail fin seat 103 can slide into the sliding groove 31, which plays a limiting and fixing role on the tail fin seat 103. The sliding groove 31 is arranged on the inner bottom wall of the insertion groove 30. The placement seat 6 is slidably connected with a slider 32 through the sliding groove 31. The upper surface of the slider 32 is fixedly connected with a positioning block 33. The setting of the positioning block 33 can make it snap into the slot 106 of the tail fin seat 103. A locking groove 35 is arranged on the lower surface of the slider 32. A plurality of second springs 34 are fixedly connected between the slider 32 and the inner side wall of the sliding groove 31. A control groove 36 is provided, and an electromagnet 37 is fixedly connected to the bottom wall of the control groove 36. A locking block 38 is slidably connected in the control groove 36. The side wall of the locking block 38 close to the slider 32 is an arc-shaped inclined surface, so as to ensure that when the slider 32 slides, the locking block 38 can be pressed down and slide into the locking groove 35. A third spring 39 is fixedly connected between the locking block 38 and the bottom wall of the control groove 36. The electromagnet 37 is connected to the controller 23 through a PLC control circuit. The PLC control circuit can be used to control the placement seat 6 currently being detected to leave the detection room after the detection of the controller 23 is completed. 8, according to the test result, the corresponding electromagnet 37 is controlled to be powered on and off. When the test is qualified, the electromagnet 37 is in a power-off state. When the test is unqualified, the electromagnet 37 is powered on and then powered off. The PLC control circuit is a prior art and will not be described in detail here. After the surfboard tail fin that has been tested is sent out of the testing room 8, the controller 23 completes the comparison and analysis, and determines whether there is a defect based on the comparison and analysis results. If there is a defect, the corresponding electromagnet 37 is powered on, generating a magnetic attraction on the locking block 38, so that the locking block 38 slides down and slides out of the locking groove 35. At this time, the second spring 34 Under the elastic force of the slider 32, the positioning block 33 slides, and the unqualified surfboard tail fin is ejected from the insertion slot 30 and leaves the turntable 4. If the test is qualified, the electromagnet 37 is energized, and the surfboard tail fin continues to stay in the insertion slot 30 and rotates with the turntable 4. When it rotates to the symmetrical position of the inspection chamber 8, the inspection personnel pull out the qualified surfboard tail fins, collect them, and then insert new surfboard tail fins to be inspected, thereby completing the screening of qualified and unqualified products while automatically loading and unloading, avoiding subsequent manual screening, greatly improving the automation degree of the equipment, and improving the inspection efficiency.

[0027] The power mechanism also includes a functional shaft 40, which is rotatably connected to the upper surface of the base 2 through a bearing, and the functional shaft 40 is fixedly connected with a fifth gear 41, and the lower surface of the turntable 4 is fixedly connected with a gear ring 42, and the fifth gear 41 is meshed with the gear ring 42, and the number of teeth of the gear ring 42 is eight times the number of teeth of the first gear 302, so that when the first gear 302 rotates one circle and meshes with the fifth gear 41, the gear ring 42 is driven to rotate, so that the gear ring 42 rotates 45°, and the placement seat 6 to be detected is accurately sent into the detection chamber 8. It should be noted that this embodiment The embodiment only shows eight groups of placement mechanisms. The number of teeth of the ring gear 42 and eight times the number of teeth of the first gear 302 are only the relationship between the number of teeth required in this embodiment. The specific quantity relationship is determined according to the number of placement mechanisms. The side wall of the chassis 7 is fixedly connected to the side block 28, and the upper surface of the side block 28 is rotatably connected to the permanent magnet column 29 through the bearing. The ring gear 42 is slidably connected to the side block 28. Through the setting of the permanent magnet column 29, when the placement seat 6 rotates into the detection chamber 8, the permanent magnet column 29 uses the magnetic attraction force to make the fourth gear 26 directly above it slide down and engage with the first gear 302.

[0028] It should be noted that the fourth gear 26 and the locking block 38 are made of ferromagnetic metal materials, and the remaining metal parts in the present invention are all made of aluminum alloy materials, which ensures light weight and high strength while not affecting the magnetic force of the permanent magnet column 29 and the electromagnet 37.

[0029] Damping pads are provided at the rotational connection between the mounting shaft 5 and the turntable 4, and at the sliding connection between the gear ring 42 and the side block 28. The setting of the damping pads ensures that there is a certain friction force in the rotation between the mounting shaft 5 and the turntable 4. Through the setting of the friction force, the mounting shaft 5 will rotate only when driven by the first gear 302, thereby preventing it from rotating due to external force. At the same time, the damping pad between the gear ring 42 and the side block 28 also ensures that there is a certain friction force at the contact point between the two. Through the friction force, the gear ring 42 will rotate only when driven by the first gear 302.

[0030] In the present invention, the tail fin seat 103 of the tail fin of the surfboard to be tested is inserted into the insertion groove 30. When the tail fin seat 103 is inserted, it abuts against the positioning block 33 and drives it to move, so that the slider 32 slides. During the sliding process of the slider 32, it contacts the locking block 38 and presses the locking block 38 downward. Then, as the slider 32 slides, when the locking block 38 is opposite to the locking groove 35, under the elastic force of the third spring 39, the locking block 38 slides into the locking groove 35 to lock the position of the slider 32.

[0031] The rotation of the servo motor 3 drives the driving shaft 301 to rotate, and the rotation of the driving shaft 301 drives the first gear 302 to rotate. When the first gear 302 rotates to engage with the fifth gear 41, it drives it to rotate, and the fifth gear 41 drives the ring gear 42 engaged with it to rotate, and the ring gear 42 drives the turntable 4 to rotate, so that the turntable 4 rotates 45° to send the tail fin of the surfboard to be tested into the testing chamber 8. At the same time, the fourth gear 26 corresponding to the placement seat 6 entering the testing chamber 8 rotates to the top of the permanent magnet column 29. Under the action of the magnetic attraction, the fourth gear 26 slides down, and the placement seat 6 and.

[0032] Then the first gear 302 continues to rotate, and meshes with the fourth gear 26 that is sucked and slides down, and drives it to rotate. The rotation of the fourth gear 26 drives the installation shaft 5 to rotate through the convex rib 25, thereby causing the placement seat 6 to rotate. The rotation of the placement seat 6 drives the tail fin of the surfboard placed thereon to rotate. During the rotation process, the tail fin of the surfboard is scanned by the 3D visual camera 9.

[0033] At the same time, when the placement seat 6 rotates, the friction wheel 14 is also driven to rotate by friction force, and the friction wheel 14 drives the second gear 15 to rotate through the linkage shaft 13, and the second gear 15 drives the third gear 17 meshing therewith to rotate, and the third gear 17 drives the movable electric block 22 to rotate through the follower shaft 16. During the first 180° rotation of the placement seat 6, the movable electric block 22 contacts the first electric ring 19, and the top lamp bead 10 lights up and emits red light, and the red light is used for fill light scanning. During the second 180° rotation of the placement seat 6, the movable electric block 22 contacts the first electric ring 19 and the second electric ring 20 at the same time, and the top and middle lamp bead 10 are in contact with each other. The red light and the green light are combined into yellow light for fill light scanning. During the third rotation of the placement seat 6 by 180°, the movable electric block 22 contacts the second electric ring 20 alone, and the middle lamp bead 10 lights up, emitting green light, and fill light scanning is performed by green light. When the placement seat 6 rotates by a fourth 180°, it contacts the second electric ring 20 and the third electric ring 21 at the same time, and the middle and bottom lamp beads 10 light up, and purple light is synthesized by green light and blue light to perform fill light scanning. Four scans are performed using four colors of fill light. After the scan is completed, the controller 23 receives the scan signal, and compares and analyzes the images generated by the four scans to analyze whether there are defects.

[0034] During the comparison and analysis process, the first gear 302 rotates and meshes with the fifth gear 41, so that the turntable 4 rotates, and the surfboard tail fin that has been tested is sent out of the testing chamber 8, and the next surfboard tail fin to be tested is sent into the testing chamber 8. After the surfboard tail fin that has been tested is sent out of the testing chamber 8, the controller 23 completes the comparison and analysis, and determines whether there is a defect based on the comparison and analysis results. If there is a defect, the corresponding electromagnet 37 is energized at this time, and a magnetic attraction force is generated on the locking block 38, so that the locking block 38 slides down and slides out of the locking groove 35. At this time, under the elastic force of the second spring 34, the slider 32 drives the positioning block 33 to slide, and the unqualified surfboard tail fin is ejected from the insertion groove 30 and leaves the turntable 4. If the test is qualified, the electromagnet 37 is energized, and the surfboard tail fin continues to stay in the insertion groove 30. When it rotates with the turntable 4 to the symmetrical position of the testing chamber 8, the inspector pulls out the qualified surfboard tail fin, collects it, and then inserts a new surfboard tail fin to be tested.
