Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a device for detecting the color uniformity of plastic mesh. Background Technology

[0002] Plastic nets are widely used in aquaculture, water conservancy projects, industrial screening, and agricultural protection. Color uniformity is one of the core indicators for measuring product quality. Uneven color not only affects the consistency of appearance, but also directly reflects problems such as imbalance of raw material ratio, poor dispersion of color masterbatch, fluctuations in molding process, or aging and degradation. This reduces the weather resistance, mechanical strength and service life of the nets, and even affects the light transmittance of aquaculture water, protective visibility and screening accuracy. Therefore, strict testing of color uniformity must be carried out in the production and quality inspection process.

[0003] However, existing detection lighting structures are mostly fixed, and the position and angle of the light illumination cannot be flexibly adjusted. For plastic nets of different specifications and structures, problems such as uneven local illumination and shadows in the detection area are very likely to occur, which seriously reduces the imaging effect of the visual camera and easily causes color recognition deviation, directly affecting the overall detection accuracy and reliability of the color uniformity of plastic nets.

[0004] To address the above issues, a device for detecting the color uniformity of plastic netting is proposed. Utility Model Content

[0005] This invention provides a device for detecting the color uniformity of plastic netting, which solves the problem mentioned in the background art that the lighting structure used for detection is mostly fixed, the angle and position of the light cannot be flexibly adjusted, and it is easy to produce light and shadow and uneven local light intensity when facing plastic netting of different specifications, which seriously affects the imaging quality of the visual camera and thus interferes with the accuracy of color uniformity detection.

[0006] This utility model provides the following technical solution: a plastic netting color uniformity detection device, including a frame, a drive motor fixedly installed on the side wall of the frame, an adjustment structure fixedly installed on the top of the frame, a slidably connected adjustment structure on the top of the frame, an assembly structure fixedly connected to the top of the adjustment structure, multiple visual cameras arranged in the middle of the assembly structure, multiple light structures rotatably connected to the inner cavity of the assembly structure, and an auxiliary structure fixedly installed on the top of the frame.

[0007] Preferably, the frame includes an assembly plate fixedly installed at one end of the drive motor. Limit sleeves are fixedly installed on both sides of the side wall of the assembly plate. A detection chamber is fixedly installed on the side wall of the assembly plate. A limit ring is fixedly connected to the top of the detection chamber. A ball is rotatably connected to the inner cavity of the limit ring. A fixing frame is rotatably connected to the inner cavity of the limit sleeve. One end of the fixing frame is fixedly installed to the output end of the drive motor. A fastening bolt is threadedly connected to one end of the fixing frame.

[0008] Preferably, the adjustment structure includes a stabilizing frame fixedly installed on the top of the detection chamber, a dual-axis motor fixedly installed in the inner cavity of the stabilizing frame, a turntable fixedly installed at the output end of the top of the stabilizing frame, multiple push columns fixedly installed on the top of the turntable, and a gear fixedly installed at the output end of the bottom of the dual-axis motor.

[0009] Preferably, the auxiliary structure includes an auxiliary frame fixedly installed on the top of the testing chamber, a positioning ring fixedly installed on the side wall of the auxiliary frame, a positioning ring slidably connected to the inner side of the positioning ring, an auxiliary ring fixedly connected to the side wall of the positioning ring, and multiple stops fixedly connected to the bottom of the auxiliary ring.

[0010] Preferably, the lighting structure includes a threaded rod rotatably connected to the inner cavity of the assembly structure, a baffle ring fixedly sleeved on the outer wall of one end of the threaded rod, a threaded tube threadedly connected to the outer wall of the threaded rod, a lamp box fixedly installed on the outer wall of the threaded tube, a circuit interface provided on the top of the lamp box, and a fluorescent lamp provided on the top of the lamp box.

[0011] Preferably, the directional adjustment structure includes a limiting frame slidably connected to the top of the limiting ring, a sliding ring fixedly connected to the bottom of the limiting frame, and multiple toothed blocks fixedly connected to the outer wall of the sliding ring.

[0012] Preferably, the assembly structure includes an assembly plate fixedly installed on the top of the limiting frame, and the top of the assembly plate has multiple limiting grooves.

[0013] This utility model has the following beneficial effects: Through the linkage structure of dual-axis motor, turntable, push column and stop block, the threaded rod and threaded tube can be driven to realize the sliding adjustment of the position of the lamp box and fluorescent lamp. It can flexibly adjust the illumination range and landing point according to the specifications of plastic net and detection area, with stronger light adaptability, avoiding the shadows and uneven lighting of fixed lights that affect the camera imaging, and ensuring the clarity and accuracy of color detection imaging.

[0014] The dual-axis motor with a one-way clutch transmission logic can independently control the adjustment of the light position and the rotation of the camera angle. During the inspection process, the lighting conditions and shooting angle can be changed in real time. By comparing and analyzing the color differences of plastic mesh under multiple working conditions, it can accurately identify subtle color unevenness defects, break through the limitations of static inspection, and further improve the accuracy of color defect recognition.

[0023] 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.

[0024] Example 1: This example aims to address the problem that existing lighting structures for detection are mostly fixed installations, which cannot flexibly adjust the angle and position of the light illumination. This leads to lighting shadows and uneven light intensity in areas with different sizes of plastic mesh, severely affecting the imaging quality of the visual camera 4 and thus interfering with the accuracy of color uniformity detection. Please refer to [link to relevant documentation]. Figures 1-6 A device for detecting the color uniformity of plastic netting includes a frame 1. A drive motor 2 is fixedly installed on the side wall of the frame 1. An adjustment structure 3 is fixedly installed on the top of the frame 1. A slidable adjustment structure 6 is slidably connected to the top of the frame 1. An assembly structure 5 is fixedly connected to the top of the adjustment structure 6. Multiple visual cameras 4 are arranged in the middle of the assembly structure 5. Multiple light structures 7 are rotatably connected to the inner cavity of the assembly structure 5. An auxiliary structure 8 is fixedly installed on the top of the frame 1. The frame 1 includes an assembly plate 11 fixedly installed at one end of the drive motor 2. Limit sleeves 12 are fixedly installed on both sides of the side wall of the assembly plate 11. A detection chamber 13 is fixedly installed on the side wall of the assembly plate 11. A limit ring 131 is fixedly connected to the top of the detection chamber 13. A ball bearing 132 is rotatably connected to the inner cavity of the limit ring 131. A fixing frame 14 is rotatably connected to the inner cavity of the limit sleeve 12. One end of the fixing frame 14 is fixedly installed to the output end of the drive motor 2. A fastening bolt 15 is threadedly connected to one end of the fixing frame 14.

[0025] The adjustment structure 3 includes a stabilizing frame 31 fixedly installed on the top of the detection chamber 13. A dual-axis motor 32 is fixedly installed inside the cavity of the stabilizing frame 31. A turntable 33 is fixedly installed at the top output end of the stabilizing frame 31. Multiple push columns 34 are fixedly installed on the top of the turntable 33. A gear 35 is fixedly installed at the bottom output end of the dual-axis motor 32. A one-way clutch is installed at the bottom output end of the dual-axis motor 32. When the bottom output end of the dual-axis motor 32 is driven alone, the gear 35 can drive the adjustment structure 6 and the assembly structure 5 to rotate synchronously. When the top output end of the dual-axis motor 32 is driven alone, the gear 35 at the bottom output end meshes with the tooth block 63, and the bottom output end is equipped with a one-way clutch. At this time, the top output end cannot drive the assembly structure 5 and the adjustment structure 6 to rotate.

[0026] The auxiliary structure 8 includes an auxiliary frame 81 fixedly installed on the top of the detection chamber 13. A positioning ring 82 is fixedly installed on the side wall of the auxiliary frame 81. A positioning ring 84 is slidably connected to the inner side of the positioning ring 82. An auxiliary ring 83 is fixedly connected to the side wall of the positioning ring 84. Multiple stops 85 are fixedly connected to the bottom of the auxiliary ring 83. The lighting structure 7 includes a threaded rod 71 rotatably connected to the inner cavity of the assembly structure 5. A baffle ring 72 is fixedly sleeved on the outer wall of one end of the threaded rod 71. A threaded tube 73 is threadedly connected to the outer wall of the threaded rod 71. A lamp box 74 is fixedly installed on the outer wall of the threaded tube 73. A circuit interface 75 is provided on the top of the lamp box 74. A fluorescent lamp 76 is provided on the top of the lamp box 74.

[0027] In this embodiment: Before testing the plastic netting, the plastic netting tube is first placed on the fixed frame 14 driven by the drive motor 2. Then, one end of the plastic netting is fixed to the outer wall of the plastic netting tube. Subsequently, the fastening bolt 15 is inserted into one end of the fixed frame 14 from the plastic netting tube and tightened. While the fixed frame 14 rotates at one end, the fastening bolt 15 presses one side of the plastic netting tube to achieve the limiting and fixing of the plastic netting tube. Then, the drive motor 2 is started. The output end of the drive motor 2 drives the fixed frame 14 to rotate. The fixed frame 14 synchronously drives the plastic netting tube to rotate, thereby wrapping and storing the plastic netting on the outer wall of the plastic netting tube.

[0028] Then, the positions of the visual camera 4 and the lighting structure 7 are adjusted, and the dual-axis motor 32 is started. The top output end of the motor drives the turntable 33 to rotate. The push column 34 on the top of the turntable 33 pushes the stop block 85, causing the positioning ring 84 to slide inside the positioning ring 82, so that the auxiliary ring 83 forms a limited rotation. At the same time, the stop block 85 pushes the baffle ring 72, and the baffle ring 72 drives the threaded rod 71 to rotate inside the assembly structure 5. Since the lamp box 74 is limited by the inner cavity of the assembly structure 5 when the threaded rod 71 rotates, the threaded tube 73 can only form a threaded transmission with the threaded rod 71, thereby driving the lamp box 74 to slide inside the inner cavity of the assembly structure 5, and simultaneously adjusting the installation position of the fluorescent lamp 76 to achieve the adjustment of the light angle and illumination range.

[0029] Example 2: This example aims to address the problem that existing visual inspection cameras often use fixed installation methods, resulting in unadjustable shooting angles and the inability to acquire images from fixed points, making it difficult to adapt to the inspection needs of plastic netting with different widths and structures. Please refer to [link / reference]. Figures 2-5 This embodiment is an improvement on the basis of embodiment 1. The adjusting structure 6 includes a limiting frame 61 that is slidably connected to the top of the limiting ring 131. A sliding ring 62 is fixedly connected to the bottom of the limiting frame 61. Multiple toothed blocks 63 are fixedly connected to the outer wall of the sliding ring 62. The assembly structure 5 includes an assembly plate 51 that is fixedly installed on the top of the limiting frame 61. Multiple limiting grooves 52 are opened on the top of the assembly plate 51.

[0030] For details, please refer to Figures 2-5 and Figure 7 When adjusting the angle of the visual camera 4, the bottom output end of the dual-axis motor 32 is started to drive the gear 35 to rotate. The gear 35 meshes with the tooth block 63 to drive the sliding ring 62 to slide along the inner side of the limiting ring 131. The inner cavity of the limiting ring 131 is provided with a ball 132. The ball 132 is limited to the inner cavity of the limiting ring 131 and can only roll. The bottom of the sliding ring 62 slides against the upper surface of the ball 132, which can improve the smoothness of the sliding ring 62. This makes it easier for the limiting frame 61 to drive the assembly plate 51 to rotate. The assembly plate 51 drives the visual camera 4 to rotate synchronously, and finally realizes the angle adjustment of the visual camera 4.

[0031] After adjusting the positions of the vision camera 4 and the lighting structure 7, the drive motor 2 can be started. The drive motor 2 pulls the plastic netting into the inner cavity of the detection chamber 13. The lighting structure 7 is pre-adjusted so that the light shines on the upper surface of the plastic netting. The color uniformity of the plastic netting can then be detected by the vision camera 4. At the same time, during the detection process of the vision camera 4, the dual-axis motor 32 can be started to adjust the angle of the lighting structure 7 or the vision camera 4, so as to adjust the lighting conditions under the detection conditions and further determine whether there are color differences on the surface of the plastic netting.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
