Description

Technical Field

[0001] The present invention belongs to the technical field of packaging box printing quality inspection, and specifically relates to a device for inspecting the industrial printing quality of packaging boxes. Background Art

[0002] In the field of packaging and printing production, the construction of a quality inspection system is of crucial strategic significance. As the core link to ensure product compliance, optimize market competitiveness, control material losses, maintain corporate reputation and fulfill regulatory obligations, it has become an industry consensus to establish an integrated detection system and configure advanced detection equipment. The current mainstream packaging box printing quality inspection device belongs to a composite function type of equipment, and its core inspection dimensions cover key parameters such as color gamut reduction accuracy, overprint position deviation control, graphic element integrity verification, and conventional printing defect identification. The aim is to ensure that the printing quality of packaging products meets the established technical specifications through a standardized inspection process, thereby synchronously improving production efficiency and the qualified rate of finished products.

[0003] The existing technical solutions have significant technical bottlenecks: Conventional industrial inspection devices mainly rely on a machine vision inspection system (with an industrial camera as the core component) to implement printing quality monitoring, and their inspection scope is limited to traditional printing elements.

[0004] When it comes to the detection requirements of laser holograms with anti-counterfeiting functions, the existing technical architecture shows fundamental defects: When the laser hologram is used as an independent detection object, the verification of its optical properties requires the configuration of a dedicated detection module, and there are limitations in the detection dimensions. Most can only complete the detection of optical reflection characteristics and apparent morphology, and cannot quantitatively evaluate the physical properties such as the adhesion and abrasion resistance between the laser hologram layer and the substrate, resulting in a two-stage detection process with physical isolation between printing quality inspection and holographic anti-counterfeiting detection. This technical path has two-fold constraints: On the one hand, two sets of detection systems need to be independently configured, directly increasing the equipment investment cost and space occupancy; on the other hand, the inspected packaging boxes need to go through two transmission and detection processes, which not only prolongs the detection cycle of a single product and ultimately affects the comprehensive detection efficiency. Summary of the Invention

[0031] Embodiment 1 Please refer to Figures 1-9, A quality inspection device for industrial printing of packaging boxes, including an inspection table 11, which facilitates the installation and placement of the conveying device 12, thus facilitating the conveyance of the box body to be inspected 13, and then the printing quality is inspected. It can be used for packaging color boxes, gift boxes, etc., and can be selected according to the actual situation to adapt to different box bodies to be inspected 13 for printing quality inspection. A conveying device 12 for conveying the box body to be inspected 13 is provided on the inspection table 11. Preferably, as shown in the figure, the conveying device 12 is a conveyor belt. Only a partial illustration of the conveyor belt is shown in the figure, and the driving device is not shown in the figure. This is a relatively mature technology and will not be elaborated here. The conveying device 12 can also be a roller conveying device, a tray conveying system, etc., as long as it can convey the box body to be inspected 13. It can be selected according to the actual inspection needs. The conveying direction of the conveying device 12 is the advancing direction. Along the advancing direction on the inspection table 11, there are sequentially arranged a physical inspection mechanism, a laser hologram quality inspection mechanism, and a printing quality inspection component, which can facilitate the inspection of the printing and laser holograms on the box body to be inspected 13 to ensure the quality of the product. For the laser hologram, it can be pasted on the box body to be inspected 13 according to the actual situation, or can be made by other methods such as physical imprinting of micro-nano structures, etc., which can improve the decorative and anti-counterfeiting properties.

[0032] Please refer to Figures 1-9 , The physical inspection mechanism includes an adjustment part and an inspection part. The adjustment part adjusts the position of the inspection part and the box body to be measured, and is used to inspect the box body to be inspected 13. The inspection part includes a scraper 65, sandpaper 66, and a wiping cotton 67. The scraper 65, sandpaper 66, and wiping cotton 67 are arranged in sequence along the advancing direction. The scraper 65, sandpaper 66, and wiping cotton 67 are used to inspect the physical properties of the laser hologram on the box body to be inspected 13. For the scraper 65, in order to avoid damaging the surface of the box body to be inspected 13, while also testing the adhesion firmness of the laser hologram, the edge or surface of the hologram is scratched to see if there are phenomena such as peeling off or flaking. The outside of the scraper 65 is wrapped with a rubber sleeve to avoid affecting the contact and ensure the detection effect. The sandpaper 66 at the rear end can gently wipe the surface of the hologram to observe whether it is prone to scratches or wear, and can also be replaced by other materials such as a soft cloth to test the wear resistance. The wiping cotton 67 at the rearmost end can wipe the surface after testing to avoid the influence of dust and other impurities on the subsequent detection effect and ensure the accuracy of the detection.

[0033] Please refer to Figures 1-9, after the box body 13 to be detected is conveyed to the physical detection mechanism station by the conveying device 12, the position between the adjustable detection part and the box body 13 to be detected can be adjusted to detect the physical properties. An adjustment part of the physical detection mechanism is arranged on the detection table 11. The adjustment part includes first hydraulic expansion rods 23 symmetrically arranged on the detection table 11. A lifting plate 21 is fixedly arranged at the output end of the first hydraulic expansion rod 23. An installation plate 22 is arranged at one end of the lifting plate 21 close to the conveying device 12, which can be made by welding or integral molding. An adjustment groove 24 is formed in the middle of the installation plate 22. A moving block is slidably matched in the adjustment groove 24. A moving plate 25 is connected with the inner wall of the adjustment groove 24 through an electric push rod 26. And limiting blocks 64 are symmetrically arranged on both side walls of the moving plate 25. Limiting grooves 63 for facilitating the limiting blocks 64 to slide along the advancing direction are formed on both side walls of the adjustment groove 24 to assist in guiding and limiting to ensure the stability during the sliding process. In order to facilitate reciprocating sliding in the limiting grooves 63, rolling balls are arranged on the end faces of the limiting blocks 64 in contact with the limiting grooves 63 to reduce the friction force in contact with the limiting grooves 63 and facilitate sliding. A scraper 65, a sandpaper 66 and a wiping cotton 67 are sequentially arranged at the bottom of the moving block to facilitate the detection of the physical properties of the laser hologram. Pressure rods 61 are equidistantly arranged under the installation plate 22. Preferably, the number of the pressure rods 61 is four groups, and it can also be two groups or six groups or other numbers. A rubber pad 62 is fixedly arranged at the bottom end of the pressure rod 61 to facilitate pressing and positioning the peripheral side of the laser hologram of the box body 13 to be detected, facilitate the subsequent physical property detection, and avoid hard contact to prevent damage to the surface of the box body 13 to be detected.

[0034] Please refer to Figures 1-9, the laser hologram quality inspection mechanism includes a rotating component and a laser hologram detection device 34. The rotating component is used to adjust the angle of the laser hologram detection device 34, which is convenient for detecting the appearance and basic optical characteristics of the laser hologram on the box body 13 to be detected. For the laser hologram detection device 34, it can be a high-resolution camera. By cooperating with the rotating component to rotate and adjust the angle, the overall pattern, line color, and layering of the laser hologram can be detected. For some holograms encrypted with fluorescent materials, an ultraviolet lamp can be used to observe whether specific fluorescent patterns or characters appear. A spectrophotometer is used to detect the diffraction efficiency of the hologram and evaluate whether its optical brightness and color saturation meet the standards. Detection is selected according to the actual situation. This is a relatively mature technology and will not be elaborated here. The rotating component is connected to the conveying device 12 through a driving mechanism. The rotating component includes fixed frames 32 symmetrically arranged on the detection table 11. A rectangular block 31 is fixedly provided at the end of the fixed frame 32. Guide grooves 33 are opened on the side walls of the two rectangular blocks 31 facing each other. Preferably, the shape of the guide groove 33 is arc-shaped, which can facilitate the sliding of the guide blocks 36 at both ends of the slider 35 in the guide groove 33, and then the angle of the laser hologram detection device 34 below can be adjusted. Guide blocks 36 are slidably fitted in both guide grooves 33. A slider 35 is fixedly arranged between the two guide blocks 36. The bottom end of the slider 35 is connected to the laser hologram detection device 34. The driving mechanism includes a toothed belt 51 arranged on one side of the conveying device 12. As Figure 2 shown, a rotating rod 52 is rotatably arranged on the detection table 11. A gear 53 meshing with the toothed belt 51 is arranged on the rotating rod 52. When the conveying device 12 works, it can drive the toothed belt 51 to move, and then the gear 53 meshing with the toothed belt 51 can drive the rotating rod 52 to rotate on the detection table 11. A rotating plate 54 is fixedly arranged at the top end of the rotating rod 52. The centers of the rotating rod 52, the gear 53, and the rotating plate 54 are on the same axis. When the gear 53 rotates, the rotating rod 52 and the rotating plate 54 rotate together. A limiting guide rod 57 is fixedly arranged on one side of the top of the rotating plate 54. A rotating member 58 is rotatably arranged on the limiting guide rod 57. The rotating member 58 can rotate 360° in the horizontal direction of the limiting guide rod 57. The rotating member 58 is connected to the slider 35 through a connecting component. The connecting component includes rotating seats 55 arranged on the side walls of the slider 35 and the rotating member 58. A connecting rod 56 is rotatably arranged between the two rotating seats 55. For the connecting rod 56, rotating balls are welded at both ends of the connecting rod 56. A rotating cavity convenient for the rotation of the rotating balls is opened inside the rotating seat 55.

[0035] Please refer to Figures 1-9, the printing quality detection component includes a mounting bracket 41 arranged on the detection table 11. The mounting bracket 41 is connected to the detection table 11 through a second hydraulic telescopic rod 42, which facilitates adjusting the overall height of the mounting bracket 41, thereby adapting to the distance between the printing detection device 43 and the box body 13 to be detected, and facilitating detection. A printing detection device 43 is arranged in the middle of the mounting bracket 41, which can be a detection element such as an optical sensor or a camera. It scans or takes pictures of the box body 13 to be detected to obtain printing image information, and then analyzes and processes it through professional software to identify various quality problems that occur during the printing process, such as inaccurate overprinting, color difference, stains, barcode defects, etc. This is a relatively mature technology and will not be elaborated here. Supplementary lights 44 are symmetrically arranged at both ends of the mounting bracket 41. The two supplementary lights 44 are located at both ends of the printing detection device 43 and provide supplementary lighting according to the actual situation without affecting the detection.

[0036] Working principle: The conveying device 12 on the detection table 11 conveys the box body 13 to be detected. After it is conveyed to the physical detection mechanism station, the conveying is paused. The first hydraulic telescopic rod 23 contracts, driving the lifting plate 21 and the mounting plate 22 to move downward. The rubber pad 62 under the pressure rod 61 contacts the surface of the box body 13 to be detected. The first hydraulic telescopic rod 23 continues to contract, and the box body 13 to be detected can be firmly fixed by the pressure rod 61 and the rubber pad 62. At the same time, the scraper 65, the sandpaper 66 and the wiping cotton 67 under the moving plate 25 all contact the box body 13 to be detected. The electric push rod 26 contracts, driving the moving plate 25 to slide in the adjustment groove 24. At the same time, the limit block 64 cooperates with the limit groove 63 to ensure the stability of the moving plate 25 during the movement in the adjustment groove 24. Then, the scraper 65, the sandpaper 66 and the wiping cotton 67 under the moving plate 25 move and contact the laser hologram one by one. The scraper 65 tests the adhesion firmness of the laser hologram by scraping the edge or surface of the hologram to see if there are phenomena such as peeling off or flaking. The sandpaper 66 can gently wipe the surface of the hologram to observe whether it is prone to scratches or abrasions, and test the abrasion resistance. The wiping cotton 67 can wipe the tested surface to avoid the influence of dust and other impurities on the subsequent detection effect. After the physical property test is completed, the first hydraulic telescopic rod 23 extends and resets, driving the lifting plate 21 and the mounting plate 22 to rise and reset. The conveying device 12 works, driving the box body 13 to be detected to continue to be conveyed. After the box body 13 to be detected after physical property detection is conveyed to the laser hologram quality detection mechanism station, when the conveying device 12 works, the toothed belt 51 moves along with it, and then the gear 53 meshing with the toothed belt 51 rotates. The rotating rod 52 and the rotating plate 54 rotate synchronously. Cooperating with the limit guide rod 57, the rotating member 58, the connecting rod 56 and the rotating seat 55 can drive the guide blocks 36 on both sides of the slider 35 to reciprocate in the guide groove 33, realizing the angle adjustment of the laser hologram detection device 34, and detecting the overall pattern, line color and layering of the laser hologram, etc. After the detection is completed, the conveying device 12 continues to convey. After it is conveyed to the printing quality detection component station, the conveying device 12 stops conveying. The printing detection device 43 cooperates with the supplementary light 44 to scan or photograph the whole box body 13 to be detected, obtain the printing image information, and then analyze and process it through professional software to identify various quality problems such as misregistration, color difference, stains, bar code defects, etc. that occur during the printing process, and complete the detection of the printing quality of the packaging box.
