Description

Technical Field

[0001] The present invention relates to the technical field of packaging box printing detection, and particularly to a quality detection device and method for corrugated paper packaging boxes. Background Art

[0002] In the modern packaging industry, corrugated paper boxes, as an important carrier for product packaging, their printing quality is crucial. Visual inspection printing technology has become a key means for detecting the printing quality of corrugated paper boxes due to its advantages such as high precision, high efficiency, and non-contact.

[0003] In the visual inspection printing operation process, first, the corrugated paper box to be detected is accurately adjusted in position and angle and placed on the conveyor. The conveyor smoothly transports it to the detection area. Immediately afterwards, the light source of the detection device is turned on, and the light evenly irradiates the printing surface of the box. The reflected light is collected by a high-resolution visual lens and imaged. After the image is transmitted to the computer system, professional image processing software sequentially performs a series of processes on the image, such as grayscale conversion, noise reduction, and edge detection, accurately extracts the characteristic information of the printed pattern, and makes a detailed comparison and analysis with a preset standard image, and finally obtains the detection result.

[0004] However, in this detection process, the problem of light interference is extremely prominent. The printing processes of corrugated paper boxes are rich and diverse, and the wide application of special processes such as hot stamping and UV printing has made the optical characteristics of the box surface complex. For example, the metallic luster of the hot stamping part on the surface of the corrugated paper box is extremely likely to produce strong specular reflection under light irradiation, and the high-gloss coating formed by UV printing will also cause light reflection. At the same time, the light source distribution in the detection environment is complex. In addition to the main light source for detection, there are also multi-directional stray lights such as workshop lighting and natural light penetrating through the windows. These lights irradiate the printing surface of the box, and the reflected lights are superimposed on each other, forming complex light spots, seriously interfering with the accurate capture and recognition of the printed pattern, text, and fine defects by the visual lens, resulting in deviations in the detection results. Summary of the Invention

[0015] The present invention also provides a usage method of a quality detection device for a corrugated paper packaging box, including the following steps: S1: First, adjust the position and angle of the corrugated paper packaging box body to be detected and place it on the conveyor. Then, start the conveyor through the console to convey the printed surface of the corrugated paper packaging box body to the front side of the visual detection head to start visual detection. During the conveying process, through the real-time fitting detection of the damage detection component, immediately perceive the condition of the printed surface of the corrugated paper packaging box body, detect each passing area, so as to detect the damage of the printed surface of the corrugated paper packaging box body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the setting of the anti-reflection component, when the present detection device visually detects the printed surface of a corrugated paper packaging box using hot stamping or UV printing, it can effectively block multi-directional stray light in the detection environment, thereby avoiding the situation where light irradiates the printed surface of the paper box and the reflected lights are superimposed on each other to form complex light spots, interfering with the detection of the printed pattern by the optical lens. To a certain extent, it improves the accuracy of the detection result. At the same time, through the setting of the black light-absorbing material on the surface of the anti-reflection belt, the anti-reflection belt can absorb the reflected light generated when the main light irradiates the hot stamping printed surface during detection, preventing secondary reflection from interfering with the detection. At the same time, through the setting and operation of the driving and adjusting component, the anti-reflection component has a flexible and variable adjustment ability. Facing a complex light source environment, it can accurately change the angles and positions of the anti-drive blocking belt and the anti-reflection belt, with better overall use and higher flexibility. At the same time, when the anti-reflection component is not in use, it can also be controlled to move to one side, with convenient operation; When the driving and adjusting component drives the anti-reflection component to adjust and operate, it will drive the conveying component, the adsorption and cleaning component, and the extrusion component to run synchronously, so as to electrostatically adsorb and remove the paper scraps and impurities adhered to the surface of the anti-reflection belt, avoid the adhesion of paper scraps and impurities from reducing the light-absorbing performance of the anti-reflection belt, ensure that the anti-reflection belt can continuously and stably exert a low-reflection effect, thereby maintaining an ideal detection environment, and at the same time can collect the paper scraps and impurities centrally to protect the cleanliness of the working environment; Through the setting and operation of the damage detection component, when the conveyor conveys and detects the main body of the corrugated paper packaging box, it can automatically conduct a comprehensive coverage detection on the printed surface of the main body of the corrugated paper packaging box to detect whether there are damaged depressions on its printed surface, realizing continuous and uninterrupted detection of the carton surface. Compared with traditional manual sampling inspection, it greatly improves the detection speed and continuity. At the same time, it can automatically mark the main body of the corrugated paper packaging box with defects, facilitating subsequent rapid sorting and rejection, and improving the overall production efficiency.

DETAILED DESCRIPTION

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figure 1 - Figure 4 and Figure 11 - Figure 14 , a quality inspection device for corrugated paper packaging boxes, including a conveying rack 1, a console 2 installed on one side of the conveying rack 1, and a visual inspection head 3 installed on one side of the console 2. Two semi-circular limiting frames 4 are symmetrically and fixedly arranged at the top of the conveying rack 1 close to the visual inspection head 3. Limiting chutes 5 are penetrated through the interiors of the two limiting frames 4. An anti-reflection component is arranged between the two limiting frames 4; the anti-reflection component includes two arc-shaped frames 6 and an anti-reflection belt 10. The two arc-shaped frames 6 are symmetrically arranged between the two limiting frames 4. The anti-reflection belt 10 is arranged between the two arc-shaped frames 6. Two limiting rollers 7 are symmetrically and rotatably installed on one side of the two arc-shaped frames 6 away from the anti-reflection belt 10. One end of each of the two limiting rollers 7 is slidably clamped inside the corresponding limiting chute 5. A driving and adjusting component is arranged at the top of one of the arc-shaped frames 6.

[0021] The conveying component includes two transmission shafts 8 and a transmission shielding belt 9. The two transmission shafts 8 are symmetrically and rotatably installed between the two arc-shaped frames 6. The transmission shielding belt 9 is sleeved and fitted around the exteriors of the two transmission shafts 8. The inner wall of the anti-reflection belt 10 is sleeved and fitted around the exterior of the transmission shielding belt 9.

[0022] Specifically, the anti-reflection belt 10 in this device is made of existing materials and is directly adhered to the exterior of the transmission shielding belt 9 to ensure that the anti-reflection belt 10 will rotate synchronously with the transmission shielding belt 9 during subsequent rotation.

[0024] A rotating rod 13 is coaxially fixed to the output shaft of the stepping motor 12. A driving gear 14 is fixedly installed at the end of the rotating rod 13 away from the stepping motor 12. The driving gear 14 is meshed with the top side of the driving rack 15.

[0025] A conveyor 34 is installed inside the top of the conveying rack 1. A corrugated paper packaging box body 35 is placed on the top of the conveyor 34.

[0026] The damage detection component includes an installation cavity 37, an insulating frame 38 and a number of insulating roller rods 42. The installation cavity 37 is longitudinally opened inside one of the limiting plates 36. The insulating frame 38 is longitudinally and fixedly installed on one inner wall of the installation cavity 37. A number of insulating roller rods 42 are all horizontally penetrated and slidably installed inside one side edge of the limiting plate 36. One side of the roller ends of a number of insulating roller rods 42 is in contact with the outer surface of one side of the corrugated paper packaging box body 35. One end of a number of insulating roller rods 42 away from the corrugated paper packaging box body 35 is fixedly installed with a connection block 41. Each connection block 41 is in contact and connected with each other. A compression spring 43 is sleeved and installed through the outside of one side of each insulating roller rod 42. The two ends of the compression spring 43 are respectively installed on one side of the connection block 41 and the insulating frame 38. Conductive block one 39 and conductive block two 40 are symmetrically installed on the outside of both sides of the insulating frame 38 close to the connection block 41. One side of the conductive block one 39 and the conductive block two 40 is respectively in contact and conduction with one side of the corresponding connection block 41. An electromagnet 44 is fixedly installed at the top of the insulating frame 38. The electromagnet 44 is connected to the conductive block two 40 through a wire. A guiding frame 45 is fixedly installed at the top of the insulating frame 38. Two auxiliary rods 46 are symmetrically and longitudinally fixedly installed inside the guiding frame 45. A slider 47 is penetrated and slidably installed through the outside of one side of the two auxiliary rods 46. One side of the slider 47 close to the adsorption end of the electromagnet 44 is fixedly installed with an iron block 48. A return spring 49 is sleeved and installed through the outside of one side of the two auxiliary rods 46. The two ends of the return spring 49 are respectively installed on one side of the guiding frame 45 and the slider 47. A marking nozzle 50 is fixedly installed at the top of the guiding frame 45. The output end of the marking nozzle 50 faces one side of the top of the corrugated paper packaging box body 35. The output end of the marking nozzle 50 is conductively installed with a pressing valve 51. The pressing trigger end of the pressing valve 51 is arranged on one side of the top of the slider 47.

[0027] In this embodiment, during the detection of the corrugated paper packaging box body 35 using hot stamping and UV printing, when switching to detect corrugated paper boxes of different sizes and shapes, or when the direction and intensity of the light source in the detection environment change, and during the detection process, when problems such as blurring and light spots caused by reflection appear in the images fed back by the visual detection device, it is necessary to change the angles of the transmission shielding belt 9 and the anti-reflection belt 10 to improve the shielding effect and ensure the accuracy of the visual detection data. During adjustment, first, the operator controls the stepper motor 12 to start through the console 2. The output shaft of the stepper motor 12 rotates to drive the rotating rod 13 and the driving gear 14 on one side to rotate. Through the connection between the driving gear 14 and the driving rack 15, and the sliding engagement of the limiting roller 7 on the side of the arc-shaped frame 6 with the internal limiting chute 5 of the limiting frame 4, when the driving gear 14 rotates, it will drive the arc-shaped frame 6, the transmission shielding belt 9, and the anti-reflection belt 10 to move between the two limiting frames 4. The operator only needs to control the rotation direction of the output shaft of the stepper motor 12 to control the positions of the transmission shielding belt 9 and the anti-reflection belt 10. In this way, this quality detection device has a flexible and variable adjustment ability. Facing a complex light source environment, it can accurately change the angles and positions of the transmission shielding belt 9 and the anti-reflection belt 10. The overall use is better and the flexibility is higher. At the same time, when the transmission shielding belt 9 and the anti-reflection belt 10 are not in use, they can also be controlled to move to the end of one side of the limiting frame 4, and the overall operation is convenient.

[0028] It should also be noted that during the inspection, the two symmetrically arranged limit plates 36 are used to limit the guide, so that the existing conveyor 34 can be more stable and will not deviate when conveying the corrugated paper packaging box body 35, ensuring that the printed surface of the corrugated paper packaging box body 35 can accurately face the visual inspection head 3. When the corrugated paper packaging box body 35 is conveyed between the two limit plates 36, the roller ends of the several insulating roller rods 42 will contact and fit the printed surface of the corrugated paper packaging box body 35, and the corrugated paper packaging box body 35 will be 5 is completely covered to ensure the comprehensiveness of subsequent inspections. As the corrugated paper packaging box body 35 continues to be transported, the roller ends of several insulating roller rods 42 will rotate in contact with the printing surface of the corrugated paper packaging box body 35. When a concave or damaged portion of the printing surface of the corrugated paper packaging box body 35 appears, the insulating roller rod 42 on the corresponding side is pressed by the pressing spring 43, causing the roller end on one side to press against the inside of the concave or damaged portion. When the insulating roller rod 42 at this location moves laterally, it will drive a The side connection blocks 41 move synchronously, so that there is a gap between the connection blocks 41, so that the connection blocks 1 39 and the connection blocks 2 40 are not connected, causing power failure, so that the electromagnet 44 is powered off. When the electromagnet 44 is powered off, the top iron block 48 loses its attraction, and the compression and rebound of the reset spring 49 are cooperated to drive the slider 47 to move upward under the guidance of the auxiliary rod 46. The slider 47 will resist the pressing valve 51 during the upward rebound and resistance process. The pressing valve 51 is turned on, so that the output end of the marking nozzle 50 is opened, so that the external The marking liquid transported into the marking nozzle 50 through the pipeline is sprayed on the surface of the corrugated paper packaging box body 35, thereby marking the corrugated paper packaging box body 35 as damaged, which is convenient for subsequent sorting. The device can work in real time during the production and transportation process of the corrugated paper packaging box body 35 without manual inspection. When the corrugated paper packaging box body 35 moves, the roller end of the insulating roller rod 42 can instantly sense the status of the printing surface and detect each area passed through, which greatly improves the speed and continuity of the detection and ensures the overall use effect.

[0029] It should also be noted that after the marking nozzle 50 sprays the mark, when the corrugated paper packaging box body 35 continues to be transported, the insulating roller rod 42 that is trapped in the damaged part will be reset, so that several connecting blocks 41 are connected, and the connecting block 1 39 and the connecting block 2 40 are connected, so that the external power supply and the electromagnet 44 are connected, so that the electromagnet 44 is energized to generate suction to attract the slider 47 to descend, so that the slider 47 is separated from the pressing valve 51, and the marking nozzle 50 stops spraying and prepares to reset for the next spraying, so that the whole can be automatically reset, ensuring the sustainable recycling of the entire device.

[0030] Example 2: Please refer to Figure 5 - Figure 6This embodiment further explains Example 1, a conveying component is provided inside the anti-reflective tape 10 between the two arc-shaped frames 6; an adsorption cleaning component is provided between the edges of the two arc-shaped frames 6 on one side close to the anti-reflective tape 10.

[0031] A one-way sprocket 16 is fixedly installed through the outside of one side of the rotating rod 13 .

[0032] Specifically, through the unidirectional rotation limitation of the one-way sprocket 16 formed by the existing structure, when the output shaft of the stepper motor 12 drives the rotating rod 13 to switch and rotate in both directions, it will only drive the one-way sprocket 16 to rotate in one direction, thereby ensuring that the transmission shaft 8 and the transmission shielding belt 9 can only switch and rotate in one direction, thereby ensuring that the overall cleaning cycle is orderly.

[0033] A second sprocket 17 is fixedly mounted on the outside of one end of the two transmission shafts 8 close to the one-way sprocket 16 , and a chain 18 is sleeved and mounted on the outside of the one-way sprocket 16 and the second sprocket 17 .

[0034] The adsorption cleaning component includes an electrostatic rod 19 and a collecting tube 24. The electrostatic rod 19 is laterally arranged on one side of the two arc-shaped frames 6 close to the anti-reflective tape 10. The collecting tube 24 is laterally fixedly installed on the outside of the two arc-shaped frames 6 close to the bottom of the electrostatic rod 19. An electrostatic generator 20 is externally connected to one end of the electrostatic rod 19. An auxiliary rotating rod 21 is fixedly installed on the outside of one end of the electrostatic rod 19. One end of the auxiliary rotating rod 21 is rotatably installed on the outside of one side of one of the arc-shaped frames 6.

[0035] In this embodiment, when the output shaft of the stepper motor 12 rotates to drive the rotating rod 13 to rotate, it will drive the one-way sprocket 16 outside the rotating rod 13 to rotate synchronously. At the same time, through the transmission sleeve of the chain 18, the one-way sprocket 16 will drive the two transmission shafts 8 to rotate synchronously when it rotates. The rotation of the two transmission shafts 8 drives the transmission shielding belt 9 of the external transmission sleeve to convey and change the surface, and also drives the anti-reflective belt 10 to rotate and change the surface synchronously. At the same time, when in use, the operator can also control the existing electrostatic generator 20 on one side to start, so that the electrostatic rod 19 connected to one side generates an electrostatic adsorption force, so as to electrostatically adsorb and remove the paper scraps and impurities adhered to the surface of the anti-reflective belt 10 rotating to one side of the electrostatic rod 19, so as to avoid the adhesion of paper scraps and impurities to reduce the light absorption performance of the anti-reflective belt 10, and ensure that the anti-reflective belt 10 can continuously and stably exert the low-reflective effect, thereby maintaining an ideal detection environment, and at the same time, the paper scraps and impurities can be collected in a centralized manner to protect the cleanliness of the working environment.

[0036] It should also be noted that, due to the non-contact cleaning principle of the static electricity rod 19, the whole can accurately remove paper scraps and impurities without touching the surface of the anti-reflection tape 10, effectively maintaining the integrity and light absorption performance of the reflective surface material, thus avoiding the wear that the traditional cleaning method may cause to the reflective surface material on the surface of the anti-reflection tape 10. For example, when using tools such as cleaning brushes, the microscopic structure on the surface of the reflective surface material may be damaged due to friction during the wiping process, thereby affecting its light absorption performance.

[0037] Embodiment Three: Please refer to Figure 7 - Figure 10 , this embodiment further describes the second embodiment. A limit gear one 22 is fixedly installed outside the rotating through end of the auxiliary rotating rod 21. A limit gear two 23 is coaxially fixedly installed outside the limit roller 7 on one side close to the limit gear one 22. One side of the limit gear one 22 is meshed and connected with one side of the limit gear two 23.

[0038] A dust collection cavity 25 is horizontally opened inside the collection cylinder 24. A collection groove 26 is horizontally penetrated and arranged inside the top end of the collection cylinder 24 close to the static electricity rod 19. The inner wall of the collection groove 26 does not contact the outer surface of the static electricity rod 19. A fixed seat 28 is fixedly arranged on the bottom inner wall of the dust collection cavity 25. A scraping plate 27 is horizontally arranged inside one side of the dust collection cavity 25 above the fixed seat 28. The top end of the scraping plate 27 is in contact and fit with the bottom outer surface of the static electricity rod 19. A valve pipe 33 is penetrated and conducted through one side of the collection cylinder 24. An extrusion assembly is arranged at the bottom end of the scraping plate 27.

[0039] The extrusion assembly includes an insulating plate 29 and a plurality of guiding rods 30. The insulating plate 29 is horizontally fixedly installed outside the bottom end of the scraping plate 27. The plurality of guiding rods 30 are slidably installed through the insulating plate 29 at equal intervals. The bottom ends of the plurality of guiding rods 30 are embedded and fixedly installed outside the top end of the fixed seat 28. A contact spring 31 is sleeved through the outside of each guiding rod 30. The two ends of the contact spring 31 are respectively installed on one side of the fixed seat 28 and the insulating plate 29. The top ends of the plurality of guiding rods 30 are all fixedly installed with limit blocks 32.

[0040] In this embodiment, when the output shaft of the stepper motor 12 rotates to drive the arc frame 6, the transmission shielding belt 9 and the anti-reflective belt 10 to move between the limit frame 4, the limit roller 7 will also roll in the limit slide groove 5 inside the limit frame 4. One of the limit rollers 7 will drive the limit gear 2 23 on one side to rotate synchronously during the rolling process. When the limit gear 23 rotates, it will drive the meshing limit gear 1 22 on one side to rotate synchronously. The rotation of the limit gear 1 22 can drive the auxiliary rotating rod 21 and the electrostatic rod 19 to rotate synchronously. When the electrostatic rod 19 rotates, the paper scraps and impurities adsorbed on the surface will be transferred into the dust collecting chamber 25 inside the collecting tube 24 through the collecting groove 26 at the top of the collecting tube 24, and then they will be scraped off by the scraper 27 that fits and contacts the bottom of the electrostatic rod 19 for centralized collection, thereby ensuring the cleanliness of the surface of the electrostatic rod 19, thereby ensuring the continuous adsorption and cleaning ability of the electrostatic rod 19 and ensuring the overall use effect.

[0041] It should also be noted that, through the limiting of several guide rods 30 and the resistance and extrusion of the resistance spring 31, the insulating plate 29 and the scraper 27 at the top will always be in resistance and fit against the surface of the electrostatic rod 19, thereby ensuring the overall cleaning effect. At the same time, after a certain period of use, the operator can open the valve tube 33 to discharge and clean the impurities inside the collection tube 24.

[0042] The present invention also provides a method for using a corrugated paper packaging box quality detection device, comprising the following steps: S1: First, adjust the position and angle of the corrugated paper packaging box body 35 to be inspected and place it on the conveyor 34, then start the conveyor 34 through the control console 2 to convey the printed surface of the corrugated paper packaging box body 35 to the front side of the visual inspection head 3, and start visual inspection. During the transportation process, the damage detection component is used to detect the condition of the printed surface of the corrugated paper packaging box body 35 in real time, and each area passed through is inspected to detect the damage of the printed surface of the corrugated paper packaging box body 35. At the same time, after the printed surface is detected to be damaged, the position can be automatically marked; S2: During the inspection process, the anti-reflective component is set and used to reduce the interference of external light sources and complete the visual inspection. At the same time, the operator can control the driving adjustment component through the console 2 to drive the anti-reflective component to rotate on the top of the corrugated paper packaging box body 35, so as to change the shielding direction of the anti-reflective component; S3: When the operator controls the driving and adjusting component to operate and adjust through the control console 2, the conveying component and the adsorption and cleaning component will be driven to operate synchronously, so as to electrostatically adsorb and clean the paper scraps and impurities adhering to the outside of the anti-reflective tape 10.
