Description

Technical Field

[0001] This invention belongs to the field of visual inspection technology, and specifically relates to an online inspection device for label surface patterns. Background Technology

[0002] The label surface pattern online inspection device is an automated device used to detect the quality of label surface patterns (such as printing defects, positional deviations, color consistency, etc.) in real time on the production line. Through optical imaging, image processing and algorithm analysis technology, it performs high-speed and high-precision non-contact visual inspection of label patterns to ensure that the labels meet the preset quality standards and provides real-time feedback of inspection results to guide production adjustments.

[0003] When performing visual inspection on a label surface pattern, a uniform and stable beam of light needs to be emitted onto the label surface through a detection head. After the light shines on the label surface, optical imaging is used to reflect whether there are any abnormalities in the pattern, thus realizing the process of visual inspection of the label. In the existing technology, the label body may have wrinkles or bends after being placed for inspection. These uneven surfaces will cause the light emitted by the detection head to not shine evenly on the label pattern, resulting in inaccurate optical information and affecting the overall visual inspection result.

[0015] Preferably, concave wheels are symmetrically fixedly connected to the outer wall of the rotating shaft, and locking blocks are symmetrically fixedly connected to the bottom of the lifting platform, with the locking blocks fitting into the inner wall of the rotating shaft.

[0016] The beneficial effects of this invention are as follows: 1. The label surface pattern online detection device of the present invention applies pressure to the bottom layer of the label body through the pressing component, fixes one end of the label, provides a stable foundation for the subsequent rolling operation of the roller, prevents the label from moving during the rolling process, ensures the rolling effect, effectively guarantees the stability of the label during the rolling and detection process, and avoids detection errors caused by label movement.

[0017] 2. The label surface pattern online detection device of the present invention, through the flattening component, allows the roller to roll along the surface of the label body after it is attached to the label body, flattening the label surface that may have wrinkles or bends, eliminating the influence of uneven label surface on the detection results, and making the label surface in a flat state so that the detection head can accurately collect information on the label surface pattern.

[0018] 3. The online label surface pattern inspection device of this invention classifies and collects label bodies into qualified and unqualified categories based on the inspection results transmitted from the control box. If the inspection result is qualified, the inspection platform flips downward when the drive component moves the rollers and the pressing component to rise and reset, causing the qualified labels to fall into the body box for storage. If the inspection result is unqualified, the inspection platform does not flip, and the labels remain on the surface of the inspection platform for easy removal by staff. This achieves automatic separation of qualified and unqualified products, improving the efficiency of product quality control. It also avoids mixing qualified and unqualified products, reducing the workload of subsequent manual sorting.

[0019] 4. The label surface pattern online detection device of the present invention, through the setting of the interlocking block and the concave wheel, can restrict the rotation of the rotating shaft. When the roller rolls along the surface of the label body, it generates a certain pressure. When the detection platform is subjected to downward pressure, the interlocking block will be tightly locked in the concave groove of the concave wheel, preventing the rotating shaft from rotating, thereby preventing the detection platform from flipping downward, providing a stable and reliable detection platform for the detection head, and ensuring that the detection head can detect the label body at a fixed position and angle.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 10As shown, the present invention provides a technical solution: an online label surface pattern detection device, including a main body box 1, detection platforms 2 symmetrically arranged on the upper surface of the main body box 1, label bodies 3 placed on the upper surface of the detection platforms 2, a support frame 4 arranged above the main body box 1, a control box 5 fixedly installed on the top of the support frame 4, a detection head 6 fixedly connected to the bottom of the control box 5, a display 10 fixedly installed on the side of the main body box 1, a leveling component arranged above the detection platforms 2, the leveling component including movable rollers 19, the rollers 19 can roll along the surface of the label bodies 3 to level the surface of the label bodies 3, a pressing component arranged on one side of the rollers 19, the pressing component positions one end of the label bodies 3 by pressing down, a driving component arranged on the side of the main body box 1 to drive the rollers 19 and the pressing component to move down, and a flipping unloading component arranged on one side of the two detection platforms 2, which can classify and unload the label bodies 3 according to the detection results.

[0025] During operation: When the device is working, the label surface pattern detection mainly relies on optical means, using infrared or ultraviolet light to test the quality of the label surface pattern, and to detect printing defects, positional deviations and color consistency; the label body consists of three parts: adhesive layer, base layer and bottom layer. The base layer directly presents the pattern, the adhesive layer enables the label to stick firmly, and the bottom layer protects the adhesive layer from dust and stains when the label is not in use. When visual inspection of the label is required, the label body 3 is placed on the upper surface of the inspection table 2. The drive component is activated first, which simultaneously drives the roller 19 and the pressing component to move downward. During the downward movement, the pressing component first applies pressure to the bottom layer of the label body 3, fixing one end and providing a stable foundation for the subsequent flattening operation. Then, the roller 19 adheres to the surface of the base layer of the label body 3. Since the pressing component fixes one end of the label body 3, the roller 19 can flatten the label body 3 as it rolls along its surface, eliminating the influence of wrinkles or bends on the inspection results. The control box 5 controls the inspection head 6 to emit specific types of light, such as infrared light or ultraviolet light. Infrared light can penetrate some surface coatings to detect deeper pattern information or material properties, and can be used to detect whether there are internal defects or uneven materials in the pattern. Ultraviolet light can be used to excite fluorescent substances on the label to detect hidden anti-counterfeiting patterns or specific marks, effectively identifying printing defects. The rolling and flattening process of the roller 19 ensures that the label surface is flat during inspection, making the inspection results more accurate and clear. After the roller 19 rolls a certain distance and no longer obstructs the detection field of the detection head 6, its continued movement will cause the support frame 4 to move laterally. This lateral movement of the support frame 4 allows the detection head 6 to perform a comprehensive inspection along the surface of the label body 3. The detection head 6 continuously collects optical information about the label surface pattern to achieve visual inspection. Finally, the roller 19 rolls to the other end of the label body 3, leveling the entire body while the detection head 6 completes its lateral movement, thus inspecting the entire pattern on the surface of the label body 3. The control box 5 can then transmit the inspection results to the display. The device 10 displays the result. If the test result is qualified, the drive component will drive the roller 19 and the pressing component to rise and reset, while the two test platforms 2 will be flipped downwards. After flipping, the qualified label body 3 will fall into the body box 1 for storage and protection. If the test result is unqualified, the drive component will drive the roller 19 and the pressing component to rise and reset, but the two test platforms 2 will not be flipped. The label body 3 will remain on the upper surface of the test platform 2. The staff can directly take out the label body 3 from the surface of the test platform 2, thereby realizing the classification and collection of qualified and unqualified products. Through the above embodiments, the pressing component applies pressure to the bottom layer of the label body 3, fixing one end of the label and providing a stable foundation for the subsequent leveling operation of the roller 19. This prevents the label from moving during the leveling process, ensuring the leveling effect and effectively guaranteeing the stability of the label during leveling and detection, avoiding detection errors caused by label movement. Through the leveling component, after the roller 19 adheres to the surface of the label body 3, it can roll along the surface of the label body 3, leveling any possible wrinkles or bends on the label surface. This eliminates the influence of uneven label surface on the detection results, ensuring the label surface is flat so that the detection head 6 can accurately collect data from the label surface. The pattern information and flat label surface ensure that the light emitted by the detection head 6 can be evenly irradiated, guaranteeing the smooth progress of the testing process. Through classified material collection, based on the test results transmitted from the control box 5, qualified and unqualified label bodies 3 are classified and collected. If the test result is qualified, when the drive component drives the roller 19 and the pressing component to rise and reset, the detection table 2 flips downwards, causing the qualified label to fall into the body box 1 for storage. If the test result is unqualified, the detection table 2 does not flip, and the label remains on the upper surface of the detection table 2 for easy removal by staff. This achieves automatic separation of qualified and unqualified products, improving the efficiency of product quality control. It avoids mixing qualified and unqualified products, reducing the workload of subsequent manual sorting.

[0026] like Figure 4 and Figure 6As shown, the sliding assembly also includes two electric slides 21, which are located on both sides above the testing platform 2. Electric sliders 22 are slidably connected to the inner walls of the electric slides 21. A rotating rod 20 is rotatably connected between the inner walls of the two electric sliders 22. The outer wall of the rotating rod 20 is fixedly connected to the inner wall of the roller 19.

[0027] During operation: Under the precise action of the drive assembly, the roller 19 descends smoothly and adheres to the surface of the label body 3, ensuring full contact with the label surface and preparing for the leveling operation. Then, the electric slide block 21 activates and drives the electric slider 22 to slide orderly along its inner wall. During the sliding process, the electric slider 22, through the rotating rod 20 connected to it, precisely drives the roller 19 to move uniformly and stably along the surface of the label body 3, effectively eliminating any wrinkles, bends, or other unevenness that may exist on the label, achieving an ideal flatness. Furthermore, when the electric slider 22 moves to the outermost edge of the electric slide block 21, it descends, causing the roller 19 to adhere tightly to the surface of the label body 3, thereby improving the leveling effect.

[0028] like Figure 6 As shown, gear 23 is fixedly connected to the outer walls of both ends of the rotating rod 20, and rack plate 24 is fixedly connected to the top of the electric slide block 21. The teeth of gear 23 can mesh with the teeth of rack plate 24 respectively.

[0029] During operation: When the roller 19 moves along the surface of the label body 3, the teeth of the gear 23 mesh with the teeth of the rack 24. The gear 23 rolls along the surface of the rack 24, which in turn drives the roller 19 to roll along the surface of the label body 3 via the rotating rod 20. During the rolling process, the roller 19, due to its close contact with the surface of the label body 3, can apply uniform and appropriate pressure to smooth out any wrinkles, bends, or other unevenness on the label surface. This ensures that the roller 19 always performs a comprehensive and meticulous smoothing operation on the label surface along the predetermined path, effectively avoiding the impact on the accuracy of subsequent label surface pattern detection due to uneven or missed smoothing.

[0030] like Figures 3 to 5 As shown, the pressing assembly includes a connecting plate 12, which is fixedly connected between one side of two electric slide blocks 21. Connecting rods 15 are symmetrically inserted into the inner wall of the connecting plate 12. A pressing block 13 is fixedly connected between the bottoms of the connecting rods 15. Multiple friction blocks 14 are fixedly connected to the bottom of the pressing block 13. Springs 16 are provided on the outer wall of each connecting rod 15. The springs 16 are fixedly connected between the top of the connecting plate 12 and the bottom of the connecting rod 15.

[0031] During operation: When the electric slide 21 begins to descend under the action of the drive assembly, the connecting plate 12, which is fixedly connected to the electric slide 21, will also descend. During the descent of the connecting plate 12, the pressing block 13, under the action of gravity and the drive of the connecting plate 12, gradually approaches the edge of the label body 3. Before the roller 19 just touches the surface of the label body 3 for leveling, the pressing block 13 and its bottom friction block 14 have already firmly pressed the edge of the label body 3. At this time, because the pressing block 13 applies a certain pressure to the label body 3, the insertion rod 15 will be subjected to this squeezing force and move upward. During the upward movement, the spring 16 is stretched. When the spring 16 is stretched, it generates an elastic force in the opposite direction of stretching. This elastic force acts in the opposite direction on the plug rod 15, thereby strengthening the downward pressure exerted by the pressure block 13 and the friction block 14 on the label body 3. This enhanced downward pressure makes the contact between the pressure block 13 and the friction block 14 and the label body 3 more tight, and it is not easy to detach due to slight external interference or minor vibrations during the operation of the device. This provides a stable and reliable fixation guarantee for the roller 19 to perform high-quality flattening operation on the surface of the label body 3, ensuring that the entire label processing process can be carried out smoothly and accurately.

[0032] like Figures 3 to 4 As shown, the drive assembly includes two hydraulic rods 18, which are fixedly connected to both sides of the main body box 1. The top of each hydraulic rod 18 is fixedly connected to a side plate 17, and a lifting platform 11 is fixedly connected to one side of each side plate 17. One lifting platform 11 is fixedly connected to one side of the connecting plate 12, and the other lifting platform 11 is fixedly connected to one side of the electric slide block 21.

[0033] During operation: When the hydraulic rod 18 retracts, it drives the lifting platform 11 to descend via the side connecting plate 17. Simultaneously, the connecting plate 12 and the electric slide 21 descend together. During the descent of the connecting plate 12, the pressing component connected below it moves downwards, ultimately pressing accurately against the edge of the label body 3, thus positioning and fixing the label body 3. When the electric slide 21 descends, the roller 19 first presses against the surface of the label body 3, and then the flattening component flattens the label body 3, eliminating wrinkles.

[0034] like Figure 2 As shown, a connecting platform 26 is fixedly connected to the side of the main body box 1. A bottom slider 25 is slidably connected to the surface of the connecting platform 26. An adjusting seat 7 is fixedly connected to the top of the bottom slider 25. A threaded rod 8 is rotatably connected to the inner wall of the adjusting seat 7. A knob 9 is fixedly connected to the top of the threaded rod 8. The outer wall of the threaded rod 8 is threadedly connected to one end of the support frame 4. One end of the support frame 4 is slidably connected to the inner wall of the adjusting seat 7 and they are mutually adapted.

[0035] During operation: When the height of the detection head 6 needs to be adjusted, the operator manually rotates the knob 9. The knob 9 will drive the threaded rod 8 to rotate, and the rotation of the threaded rod 8 will cause the support frame 4 to slide up and down along the inner wall of the adjustment seat 7, thereby adjusting the height of the support frame 4. Before testing, the operator can adjust the height of the detection head 6 in advance according to the specifications of the label body 3 and the testing requirements by adjusting the height of the support frame 4. Therefore, when performing visual inspection, the detection head 6 can maintain the optimal testing position with the label body 3. In addition, after the roller 19 moves a certain distance along the surface of the label body 3, it can drive the bottom slider 25 to move along the surface of the connecting table 26, thereby enabling the detection head 6 to move along the surface of the label body 3 for comprehensive testing.

[0036] like Figures 2 to 3 As shown, a push plate 30 is rotatably connected to one end of the rotating rod 20. Two fixed plates 27 are fixedly connected above the connecting platform 26. A guide rod 28 is fixedly connected between the two fixed plates 27. The bottom slider 25 is slidably connected to the guide rod 28. A return spring 29 is fixedly connected to one side of the bottom slider 25. The end of the return spring 29 away from the bottom slider 25 is fixedly connected to one side of one of the fixed plates 27.

[0037] During operation: When the roller 19 first moves, it will drive the push plate 30 to gradually approach one side of the adjusting seat 7. When the roller 19 moves to the test range of the detection head 6 without obstructing it, as it continues to move, the push plate 30 will fit against one side of the adjusting seat 7 and push the adjusting seat 7 to move together with it. Therefore, the detection head 6 can move along with it. When the adjusting seat 7 moves, the bottom slider 25 can slide along the surface of the guide rod 28. During the sliding process, the return spring 29 is squeezed and deformed. After the overall test is completed, when the roller 19 moves in the opposite direction to reset, the entire adjusting seat 7 will also reset under the elastic force of the return spring 29, so that the detection head 6 returns to its initial position.

[0038] like Figures 8 to 10 As shown, the sorting and unloading collection includes two rotating shafts 31. The two rotating shafts 31 are fixedly connected to the inner wall of one end of the two detection platforms 2 respectively. The rotating shafts 31 are rotatably connected to the inner wall of the main body box 1. Gears 36 are fixedly connected to both ends of the rotating shafts 31. Moving blocks 35 are slidably connected to the inner wall of the lifting platform 11. A rack plate 37 is fixedly connected to the bottom of the moving block 35. The teeth of the rack plate 37 can mesh with the teeth of the gears 36. A magnetic component that drives the moving blocks 35 to move is provided inside the lifting platform 11.

[0039] During operation: Initially, both testing platforms 2 are flat, and when the lifting platform 11 descends, the rack plate 37 does not mesh with the teeth of the gear 36. After the test is completed, if the test result is qualified, the magnetic component is activated, causing the moving block 35 to move. The movement of the moving block 35 will bring the rack plate 37 closer to the gear 36, forming a meshing relationship. Therefore, after the test is completed, when the lifting platform 11 rises to reset, the rack plate 37 and the gear 36 mesh. Thus, when the lifting platform 11 descends to reset, it can drive the gear 36 to rotate. When the gear 36 rotates, it will rotate through the rotating shaft 31. When the rotating shaft 31 rotates, it will cause the testing platform 2 to rotate around the rotating shaft 31 as the fulcrum, thereby causing both testing platforms 2 to flip downwards simultaneously for unloading. If the test result is unqualified, the magnetic component will not work, the testing platform 2 will not flip, and the operator can normally remove the tested label body 3 from the surface of the testing platform 2.

[0040] like Figures 8 to 10 As shown, the magnetic component includes two electromagnets 34, which are fixedly connected to the inner wall of the lifting platform 11. The moving block 35 is made of iron material that can be attracted by the electromagnets 34. A second reset spring 38 is fixedly connected to one side of each moving block 35. The end of the second reset spring 38 away from the moving block 35 is fixedly connected to one side of the side plate 17.

[0041] During operation: When the test result is qualified, the electromagnet 34 is energized, and the electromagnet 34 generates magnetic force to attract the moving block 35, causing the moving block 35 to move towards it and stick together. When the moving block 35 moves, it will squeeze the second return spring 38 and deform. When the moving block 35 and the electromagnet 34 stick together, when the lifting platform 11 rises, the rack plate 37 and the gear 36 will mesh, thereby causing the two testing platforms 2 to flip and unload. After the two mesh, after the lifting platform 11 is reset, the electromagnet 34 is de-energized. In this way, the moving block 35 will slide back along the inner wall of the lifting platform 11 under the elastic force of the second return spring 38, so that the rack plate 37 can return to the initial position.

[0042] like Figures 9 to 10 As shown, concave wheels 32 are symmetrically fixedly connected to the outer wall of the rotating shaft 31, and interlocking blocks 33 are symmetrically fixedly connected to the bottom of the lifting platform 11. The interlocking blocks 33 fit into the inner wall of the rotating shaft 31.

[0043] During operation: When the inspection table 2 is in a flat state, the notch of the concave wheel 32 is precisely aligned with the bottom of the insert block 33. When the lifting platform 11 begins to descend, the insert block 33 moves downward along with the lifting platform 11. During the descent, the insert block 33 is inserted into the notch of the concave wheel 32 in a smooth and precise manner, which can restrict the rotation of the rotating shaft 31. When the roller 19 rolls along the surface of the label body 3, it generates a certain pressure. When the inspection table 2 is subjected to downward pressure, the insert block 33 will be tightly locked in place. In the recess of the concave wheel 32, the rotating shaft 31 is prevented from rotating, thereby preventing the detection table 2 from flipping downwards. This provides a stable and reliable detection platform for the detection head 6, ensuring that the detection head 6 can detect the label body 3 at a fixed position and angle, improving the accuracy and stability of the detection, and avoiding detection errors caused by the shaking or flipping of the detection table 2. When the lifting platform 11 rises, the insert block 33 will first disengage from the recess of the concave wheel 32, and then the rack plate 2 37 will mesh with the gear 2 36 to flip and unload the material.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
