Description

Technical Field

[0001] The present invention relates to the technical field of packaging box inspection equipment, and in particular to a packaging box printing quality inspection device. Background Art

[0002] It is very important to conduct quality inspection in the packaging printing process. Quality inspection is one of the important means to ensure product quality, improve product competitiveness, reduce resource waste, protect brand image and meet regulatory requirements. By establishing an effective quality inspection system and adopting advanced inspection technology and equipment, the quality of printed products and corporate competitiveness can be effectively improved. The packaging box printing quality inspection device is a multifunctional device. Its functions mainly include detecting printing color accuracy, printing position accuracy, printing pattern integrity, printing quality defects, etc., to help manufacturers ensure that the packaging box printing quality meets the requirements and improve product quality and production efficiency.

[0003] In the related technology, the utility model patent with application number CN202121913979.3 discloses a packaging box industrial printing quality inspection device, including a second straight plate, the lower end of the second straight plate is symmetrically and detachably connected to two gantries, the lower end of the second straight plate is fixedly connected to a main color industrial camera and the main color industrial camera is located between the two gantries, the first straight plate is arranged on both the front and rear sides of the second straight plate and the lower end of the first straight plate is detachably connected to the two gantries, the lower end of the first straight plate is movably installed with a secondary color industrial camera arranged inwardly inclined, and a number of adjustment through holes are equidistantly arranged front and back at the upper end of the gantry. This design realizes rapid disassembly and assembly of the main color industrial camera and the secondary color industrial camera, facilitates assembly and maintenance, and can also adjust the front and rear positions of the secondary color industrial camera, with high applicability. However, the device still has the following problems: in order to ensure that multiple color industrial cameras can fully cover the packaging box, when it is necessary to inspect packaging boxes of different sizes, it is often necessary to adjust the horizontal position and pitch angle of multiple color industrial cameras separately. The device can only manually disassemble the color industrial camera, and then find a suitable position to install the color industrial camera, which has the disadvantages of cumbersome operation and time-consuming adjustment. In particular, when it is found that the position of the color industrial camera needs to be fine-tuned during the quality inspection process, it is necessary to stop the machine for manual disassembly and installation, which greatly prolongs the time spent on adjustment and affects the work efficiency of quality inspection.

[0068] See also Figure 1-Figure 10 , an embodiment of the present invention provides a packaging box printing quality inspection device, including a frame 10, a conveying device 20, a support component 30 and a plurality of visual inspection components 40;

[0069] Specifically, the conveying device 20 is installed on the frame 10, and the conveying device 20 is used to support the packaging box and convey it in the horizontal direction; preferably, the conveying device 20 includes an active roller, a driven roller arranged on both sides of the frame 10, and a motor arranged on the frame 10 and connected to and driving the active roller to rotate, and the conveyor belt is tensioned between the active roller and the driven roller.

[0070] Specifically, the support assembly 30 includes a first bracket 31 and a second bracket 32 ​​symmetrically mounted on both sides of the frame 10 in the length direction, and mutually symmetrical guide grooves 33 are provided on the upper opposite sides of the first bracket 31 and the second bracket 32;

[0071] Specifically, multiple groups of visual inspection components 40 are installed on the support component 30 at intervals along the length direction of the frame 10; each group of visual inspection components includes a sliding seat 41, two sliding frames 42, a horizontal drive mechanism 43, an industrial camera 44 and a rotation drive mechanism 45; one end of the two sliding frames 42 is fixedly connected to the two ends of the sliding seat 41, and the other ends of the two sliding frames 42 are slidably inserted into the two guide grooves 33; the output end of the horizontal drive mechanism 43 is connected to the sliding seat 41, and the horizontal drive mechanism 43 is used for the sliding seat 41 to reciprocate along the length direction of the guide groove 33; the industrial camera 44 is rotatably installed at the lower part of the sliding seat 41, and the rotation drive mechanism 45 is fixedly installed on the sliding seat 41, and the rotation drive mechanism 45 is used to drive the industrial camera 44 to rotate around the Y axis to adjust the shooting angle of the industrial camera 44. Preferably, the number of visual inspection components 40 is three groups, which are installed on the support component 30 at equal intervals along the length direction of the frame 10.

[0072] On the basis of the above structure, during the working process, the packaging box is placed on the conveying device 20, and then is stably and uniformly conveyed to the detection area in the horizontal direction. The design of the conveying device 20 ensures that the position and posture of the packaging box remain stable during the conveying process so that the subsequent visual inspection can be carried out accurately. When the packaging box enters the inspection area, multiple groups of visual inspection components 40 start to work in sequence. Each group of visual inspection components 40 includes a sliding seat 41, a sliding frame 42, a horizontal drive mechanism 43, an industrial camera 44 and a rotary drive mechanism 45. The horizontal drive mechanism 43 drives the sliding seat 41 to reciprocate along the guide groove 33 in the length direction of the frame 10. Since one end of the two sliding frames 42 is fixedly connected to the sliding seat 41 and the other end is inserted into the guide groove 33, the sliding seat 41 can move stably and accurately along the guide groove 33, thereby driving the industrial camera 44 to scan the packaging box comprehensively. During the movement of the industrial camera 44, it will continue to capture the image of the packaging box. The rotary drive mechanism 45 is responsible for adjusting the shooting angle of the industrial camera 44 so that it can capture all sides of the packaging box, thereby ensuring comprehensive inspection. The captured image is transmitted to the processing system for analysis. The processing system uses advanced image processing algorithms to identify and evaluate the printing quality, such as color accuracy, printing clarity, presence or absence of stains or defects, etc. These evaluation results are compared with the preset quality standards to determine whether the printing quality of the packaging box is qualified. In this way, the present invention can ensure that packaging boxes of different sizes are fully tested for printing quality during the transportation process by combining the conveying device 20, horizontal movement and rotation adjustment. The conveying device 20 can continuously and stably convey the packaging box to the detection area, ensuring that each packaging box can be accurately delivered to the designated position for detection, improving the efficiency of detection, and reducing the time for manual handling and positioning. The horizontal movement function enables the detection device to move along the length direction of the packaging box, ensuring that every part of the packaging box can be detected without leaving dead angles. The rotation adjustment allows the detection device to shoot and detect the packaging box from different angles, further enhancing the comprehensiveness of the detection. Due to the flexibility of horizontal movement and rotation adjustment, the detection device can easily transition from detecting a small packaging box to detecting a large packaging box, only simple parameter adjustment is required, and there is no need to frequently replace or adjust the detection device. In addition, the multiple sets of visual inspection components 40 can improve the comprehensiveness of inspection, defect recognition capability, production efficiency, product quality, and data analysis accuracy by adjusting different angles of the industrial camera 44. These benefits work together in the production process, making the packaging box printing quality inspection more efficient, accurate, and reliable.

[0073] In a preferred embodiment of the present invention, the sliding seat 41 includes a horizontal support plate 411 and two vertical connecting plates 412 extending vertically downward from the bottom surface of the horizontal support plate 411;

[0074] The sliding frame 42 includes a transverse plug-in plate 421 , a vertical extension plate 422 extending vertically upward from one end of the transverse plug-in plate 421 , and a transverse connecting plate 423 extending from one end of the vertical extension plate 422 ;

[0075] The transverse connecting plates 423 of the two sliding frames 42 are fixedly connected to the two ends of the horizontal supporting plate 411 through the detachable connecting structures 50 , and the transverse plug-in plates 421 of the two sliding frames 42 are slidably plugged into the two guide grooves 33 .

[0076] This structural design enables the visual inspection assembly 40 to move horizontally smoothly and accurately on the frame 10, thereby achieving comprehensive inspection of each part of the packaging box. At the same time, the detachable connection method also improves the maintainability and flexibility of the equipment.

[0077] In a preferred embodiment of the present invention, the detachable connection structure 50 includes a cover plate 51, a first threaded rod 52, a first locking nut 53 and a guide rod 54;

[0078] The guide rod 54 is fixedly mounted on one end of the horizontal support plate 411 along the vertical direction;

[0079] The first threaded rod 52 is fixedly mounted on one end of the transverse connecting plate 423 along the vertical direction;

[0080] The two ends of the cover plate 51 are respectively provided with a sleeve hole, one end of the cover plate 51 is sleeved on the guide rod 54 through the sleeve hole, and the other end of the cover plate 51 is sleeved on the first threaded rod 52 through the sleeve hole;

[0081] The first locking nut 53 is threadedly connected to the first threaded rod 52, and the first locking nut 53 is used to lock or unlock the cover plate 51, so that the first locking nut 53 is in a locked state or a released state; when the first locking nut 53 is in a released state, the horizontal support plate 411 and the transverse connecting plate 423 can be separated from each other; when the first locking nut 53 is in a locked state, the horizontal support plate 411 and the transverse connecting plate 423 are relatively fixed.

[0082] On the basis of the above structure, when the first locking nut 53 is in a released state, the cover plate 51 can move freely on the guide rod 54 and the first threaded rod 52. This means that the horizontal support plate 411 and the transverse connecting plate 423 can be separated from each other, thereby facilitating disassembly and assembly. When the cover plate 51 is locked with the first locking nut 53, the cover plate 51 is fixed between the guide rod 54 and the first threaded rod 52, which makes the horizontal support plate 411 and the transverse connecting plate 423 relatively fixed, ensuring the stability and rigidity of the structure. This design not only provides a stable connection method, but also allows the user to quickly disassemble and assemble when necessary.

[0083] In a preferred embodiment of the present invention, a plurality of clamping strips 511 distributed along the width direction of the cover plate 51 are provided on the bottom surface of the cover plate 51, and a plurality of clamping grooves 4111 are provided on the upper surface of the horizontal support plate 411. When the first locking nut 53 is in a locked state, the plurality of clamping strips 511 are clamped in a one-to-one correspondence with the plurality of clamping grooves 4111.

[0084] On the basis of the above structure, when the first locking nut 53 is tightened to put the cover plate 51 in a locked state, the clamping strip 511 on the bottom surface of the cover plate 51 will be clamped into the clamping groove 4111 on the upper surface of the horizontal support plate 411 one by one. Through the clamping connection between the clamping strip 511 and the clamping groove 4111, the connection structure can maintain relative stability when subjected to external force, reducing vibration and shaking. The matching design of the clamping strip 511 and the clamping groove 4111 ensures that the cover plate 51 can be accurately aligned with the horizontal support plate 411 after locking, thereby ensuring the accurate installation and positioning of the detection equipment. Although the clamping design enhances the connection stability, when disassembly is required, the cover plate 51 can be easily separated from the horizontal support plate 411 by loosening the first locking nut 53, which has the advantage of easy disassembly.

[0085] In a preferred embodiment of the present invention, a plurality of plug holes 4112 are provided on the bottom surface of the horizontal support plate 411, and a plurality of plug blocks 4231 are provided on the upper surface of the transverse connecting plate 423, and the plurality of plug blocks 4231 are plugged into the plurality of plug holes 4112 one by one. Thus, when the horizontal support plate 411 and the transverse connecting plate 423 need to be connected together, the plug blocks 4231 on the transverse connecting plate 423 can be aligned with the plug holes 4112 on the horizontal support plate 411 and then inserted. This plug-in design helps to quickly locate and align the two components, and also provides a certain structural stability.

[0086] In a preferred embodiment of the present invention, a plurality of balls 4211 are respectively embedded in the upper and lower surfaces of the transverse plug-in board 421, and the plurality of balls 4211 located at the upper side are all in contact with the inner top wall of the guide groove 33, and the plurality of balls 4211 located at the lower side are all in contact with the inner bottom wall of the guide groove 33. In this way, by embedding the balls 4211 on the upper and lower surfaces of the transverse plug-in board 421 and contacting with the inner wall of the guide groove 33, sliding friction can be effectively reduced, sliding efficiency and stability can be improved, and the service life of the device can also be extended.

[0087] In a preferred embodiment of the present invention, the horizontal driving mechanism 43 includes a guide column 431, a first motor 432, a connecting frame 433, a first gear 434, a second gear 435, a first connecting rod 436 and a second connecting rod 437;

[0088] The guide column 431 is fixedly mounted on the upper portion of the sliding seat 41;

[0089] The first motor 432 is fixedly mounted on the first bracket 31 along the vertical direction.

[0090] The connecting frame 433 is fixedly mounted on the first bracket 31 and is located on one side of the first motor 432;

[0091] The first gear 434 is fixedly mounted on the output shaft of the first motor 432;

[0092] The second gear 435 is rotatably mounted on the connecting frame 433, and the second gear 435 is meshed with the first gear 434; a fixing column 4351 is provided on the top surface of the second gear 435;

[0093] One end of the first connecting rod 436 is hinged to the guide column 431 , the other end of the first connecting rod 436 is hinged to one end of the second connecting rod 437 , and the other end of the second connecting rod 437 is fixedly connected to the fixing column.

[0094] On the basis of the above structure, when the first motor 432 is started, it generates a rotational power. The output shaft of the first motor 432 is fixedly connected to the first gear 434, so the rotation of the motor is directly transmitted to the first gear 434, causing it to rotate. The first gear 434 and the second gear 435 mesh with each other to form a gear transmission system. When the first gear 434 rotates, it drives the second gear 435 to rotate in the opposite direction. The fixed column on the top surface of the second gear 435 is fixedly connected to one end of the second connecting rod 437. The other end of the second connecting rod 437 is hinged to one end of the first connecting rod 436, and the other end of the first connecting rod 436 is hinged to the guide column 431. When the second gear 435 rotates, the second connecting rod 437 is driven to move through the fixed column, thereby causing the first connecting rod 436 to swing around the guide column 431. Due to the design of the connecting rod mechanism, when the first connecting rod 436 swings, its overall movement is converted into a horizontal drive. This design can effectively convert the rotational motion of the motor into a horizontal linear motion. Thus, the horizontal drive mechanism 43 has the advantages of efficient and stable power transmission, precise motion control, compact and reliable structure, and easy maintenance and upkeep.

[0095] In a preferred embodiment of the present invention, the guide column 431 is fixedly mounted on the upper portion of the sliding seat 41 via an adjusting mechanism 60 , and the adjusting mechanism 60 is used to adjust the height of the guide column 431 .

[0096] In a preferred embodiment of the present invention, the adjustment mechanism 60 includes a mounting frame 61, a second threaded rod 62, and a second locking nut 63;

[0097] The mounting frame 61 includes a horizontal fixing plate 611 and two vertical support plates 612 extending vertically downward from both ends of the bottom surface of the horizontal fixing plate 611; a threaded hole is provided in the middle of the horizontal fixing plate 611; the two vertical support plates 612 are respectively fixedly mounted on the top surface of the horizontal support plate 411;

[0098] The second threaded rod 62 is threadedly connected to the threaded hole; the top of the second threaded rod 62 is fixedly connected to the bottom surface of the guide column 431;

[0099] The second locking nut 63 is threadedly connected to the upper part of the second threaded rod 62 and abuts against the top surface of the transverse fixing plate 611; the second locking nut 63 is rotated to move the second threaded rod 62 upward until the second threaded rod 62 is separated from the threaded hole of the transverse fixing plate 611, the rotation of the second locking nut 63 is stopped, and the first connecting rod 436 is moved to move it out from above the mounting bracket 61.

[0100] On the basis of the above structure, when it is necessary to lock the position of the second threaded rod 62, it can be achieved by rotating the second locking nut 63. When the second locking nut 63 is tightened, it will fit tightly with the transverse fixing plate 611, thereby preventing the second threaded rod 62 from further rotating or moving. By rotating the second threaded rod 62, the height of the guide column 431 can be adjusted, and then the position of the entire horizontal drive mechanism 43 can be adjusted. When adjusted to a suitable position, the position of the second threaded rod 62 is locked by tightening the second locking nut 63. When necessary, the second locking nut 63 can be rotated to loosen the second threaded rod 62 to move the second threaded rod 62 up until it is separated from the threaded hole of the transverse fixing plate 611. At this time, the first connecting rod 436 can be moved to move it out from directly above the mounting bracket 61, which provides convenience for subsequent maintenance or adjustment.

[0101] In a preferred embodiment of the present invention, the rotation driving mechanism 45 includes a second motor 451, a rotating shaft 452, and a camera fixing bracket 453;

[0102] Both ends of the rotating shaft 452 are rotatably mounted between the two vertical connecting plates 412;

[0103] The second motor 451 is fixedly mounted on a vertical connecting plate 412, and the output shaft of the second motor 451 is fixedly connected to one end of the rotating shaft 452;

[0104] The camera fixing frame 453 is fixedly installed at the middle part of the rotating shaft 452;

[0105] The industrial camera 44 is fixedly mounted on the camera fixing bracket 453 .

[0106] When the second motor 451 is started, its output shaft drives the rotating shaft 452 to rotate. Since the camera fixing frame 453 and the industrial camera 44 are both fixed on the rotating shaft 452, they rotate with the rotation of the rotating shaft 452. This design enables the industrial camera 44 to be flexibly adjusted in angle, greatly improving the flexibility and coverage of shooting.
