Description

Technical Field

[0001] This utility model belongs to the field of online visual labeling machine technology, specifically relating to an online visual labeling machine with a correction structure. Background Technology

[0002] Online vision labeling machines are industrial equipment that integrates mechanical automation, visual recognition, and intelligent control technologies. They are widely used in packaging production lines in industries such as food, pharmaceuticals, and daily chemicals. Their core principle involves using a high-speed industrial camera to capture product images in real time, combining this with AI algorithms and pre-set parameters to accurately locate the labeling position. The machine then drives a robotic arm or labeling head to complete the high-speed, high-precision label application, with an error controlled within ±1mm. Compared to traditional labeling equipment, this machine offers significant advantages: it can adapt to diverse products such as round bottles, square boxes, and irregularly shaped items; it supports dynamic adjustment of the labeling position and angle, and is compatible with different label sizes; it has a built-in fault warning system, reducing the frequency of manual intervention. Its non-contact detection avoids product damage, and its labeling efficiency of up to 300 pieces per minute effectively improves the automation level of the production line. Simultaneously, the equipment's data management system enables full-process traceability of the labeling process, meeting the dual demands of modern industry for quality management and control as well as production efficiency.

[0003] Currently, existing online visual labeling machines typically require a conveyor to transport the items to be labeled to the bottom of the machine. The labeling components then apply the labels when the items are directly beneath the machine. However, during the transport of items, the conveyor belt on traditional online visual labeling machines is prone to shifting to either side. This necessitates timely intervention from staff to prevent the items from falling off the conveyor belt, which could reduce the labeling efficiency of the online visual labeling machine. Utility Model Content

[0004] The purpose of this invention is to provide an online visual labeling machine with a correction structure, aiming to solve the problem that existing online visual labeling machines typically require a conveyor to transport the items to be labeled to the bottom of the machine body, and then the labeling components apply the labels when the items are directly under the machine body. However, in traditional online visual labeling machines, the items on the conveyor belt are easily shifted to the sides by the conveyor belt during transport. Therefore, operators need to intervene in time to prevent the items to be labeled from falling off the conveyor belt, which may reduce the labeling efficiency of the online visual labeling machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an online visual labeling machine with a correction structure, comprising a labeling machine base, a labeling machine body mounted on the top of the labeling machine base, a conveyor mounted between the labeling machine base and the labeling machine body, and a fixing frame fixedly connected to the outer wall of the labeling machine base;

[0006] A motor is installed at one end of the fixed frame, and a bidirectional threaded rod is connected to the output end of the motor. Two threaded connecting sleeves are threadedly connected to the outer wall of the bidirectional threaded rod. A connecting frame is fixedly connected to the bottom of the two threaded connecting sleeves, and a guide plate is installed at the end of the connecting frame away from the threaded connecting sleeve.

[0007] As a preferred embodiment of the online visual labeling machine with a correction structure according to this utility model, the top of the two threaded connecting sleeves is fixedly connected to a movable block, and the inner side of the fixed frame is fixedly connected to a guide rod.

[0008] In a preferred embodiment of this utility model of an online visual labeling machine with a correction structure, the end of the movable block away from the threaded connecting sleeve is sleeved on the outer wall of the guide rod.

[0009] In a preferred embodiment of this utility model of an online visual labeling machine with a correction structure, the end of the bidirectional threaded rod away from the motor is connected to the inner wall of the fixed frame via a bearing to form a rotating connection structure.

[0010] As a preferred embodiment of the online visual labeling machine with a correction structure according to this utility model, there are two guide plates that are symmetrically distributed, and the bottom of the two guide plates is higher than the conveyor.

[0011] As a preferred embodiment of the online visual labeling machine with a correction structure according to this utility model, a fixing block is fixedly connected to the inner wall of the fixing frame, a first magnetic block is bonded to the outer wall of the fixing block, a cover plate is hinged to the outer wall of the fixing frame, and a second magnetic block is bonded to the inner side of the cover plate.

[0012] As a preferred embodiment of the online visual labeling machine with a correction structure according to this utility model, one end of the cover plate can form a magnetic attraction structure with the fixed frame through a fixing block, a first magnetic block, and a second magnetic block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting two symmetrically distributed guide plates on the conveyor, the items to be labeled can be guided, thereby correcting any misalignment on the conveyor. A motor drives a bidirectional threaded rod to rotate, causing the threaded connecting sleeve on the outer wall of the rod to move the connecting frame in opposite directions. One end of the connecting frame then moves the two guide plates together, adjusting the spacing between the two symmetrically distributed guide plates to guide and correct items of different sizes, thus improving the efficiency of the online vision labeling machine.

[0015] With the arrangement of the fixing block, the first magnetic block, the cover plate, and the second magnetic block, when maintenance of the internal structure of the fixing frame is required, the first magnetic block and the second magnetic block are separated by flipping the cover plate. When the cover plate is flipped in the opposite direction, the second magnetic block on the cover plate will attract the first magnetic block. At this time, the cover plate will not swing during the operation of the equipment, thus facilitating subsequent maintenance by the staff. Attached Figure Description

[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] Please see Figures 1-5 The present invention provides the following technical solution: an online visual labeling machine with a correction structure, including a labeling machine base 1, a labeling machine body 2 installed on the top of the labeling machine base 1, a conveyor 3 installed between the labeling machine base 1 and the labeling machine body 2, and a fixing frame 4 fixedly connected to the outer wall of the labeling machine base 1.

[0025] A motor 5 is installed at one end of the fixed frame 4. A bidirectional threaded rod 6 is connected to the output end of the motor 5. Two threaded connecting sleeves 7 are threadedly connected to the outer wall of the bidirectional threaded rod 6. A connecting frame 8 is fixedly connected to the bottom of the two threaded connecting sleeves 7. A guide plate 9 is installed at the end of the connecting frame 8 away from the threaded connecting sleeves 7.

[0026] It is important to note that when the target object enters the labeling area at the bottom of the labeling machine body 2 via the conveyor belt of conveyor 3, a sensor such as a photoelectric sensor will trigger the camera to acquire an image. The equipment uses image processing algorithms such as edge detection, template matching, and feature point extraction to identify key features of the target object, such as contours, edges, and specific markings. Then, based on the image processing results, the X, Y, and Z coordinates and the angle of rotation of the label to be pasted are calculated. At this time, the label is accurately transported from the label roll or label box to the labeling position through a conveying mechanism such as a label suction head or rollers. Then, based on the calculated coordinates and angles, the labeling head, such as a vacuum suction cup or a pneumatic pressure head, accurately attaches the label to the target object.

[0027] It is also important to note that online vision labeling machines are typically equipped with high-resolution industrial cameras, such as CCD or CMOS cameras, and light source systems to acquire images of the target object in real time.

[0028] Preferably, the top of the two threaded connecting sleeves 7 is fixedly connected to a movable block 10, the inner side of the fixed frame 4 is fixedly connected to a guide rod 11, the end of the movable block 10 away from the threaded connecting sleeve 7 is sleeved on the outer wall of the guide rod 11, the end of the bidirectional threaded rod 6 away from the motor 5 is connected to the inner wall of the fixed frame 4 through a bearing to form a rotating connection structure, and two guide plates 9 are provided and symmetrically distributed, the bottom of the two guide plates 9 is higher than the conveyor 3.

[0029] In practical use, by setting two symmetrically distributed guide plates 9 on the conveyor 3, the items that need to be labeled can be guided, thereby correcting the items that are offset on the conveyor 3. The motor 5 drives the bidirectional threaded rod 6 to rotate clockwise, so that the threaded connecting sleeve 7 connected to the outer wall of the bidirectional threaded rod 6 can drive the connecting frame 8 to move towards each other. One end of the connecting frame 8 will drive the two guide plates 9 to move towards each other together.

[0030] Conversely, the motor 5 drives the bidirectional threaded rod 6 to rotate counterclockwise, which causes the threaded connecting sleeve 7 connected to the outer wall of the bidirectional threaded rod 6 to drive the connecting frame 8 to move in opposite directions. One end of the connecting frame 8 will drive the two guide plates 9 to move in opposite directions together. Thus, the above structure can adjust the spacing between the two symmetrically distributed guide plates 9 to guide and correct items of different sizes, thereby improving the working efficiency of the online vision labeling machine.

[0031] Preferably, a fixing block 12 is fixedly connected to the inner wall of the fixing frame 4, a first magnetic block 13 is bonded to the outer wall of the fixing block 12, a cover plate 14 is hinged to the outer wall of the fixing frame 4, a second magnetic block 15 is bonded to the inner side of the cover plate 14, and one end of the cover plate 14 can form a magnetic attraction structure with the fixing frame 4 through the fixing block 12, the first magnetic block 13, and the second magnetic block 15.

[0032] In practical use, by setting up the fixing block 12, the first magnetic block 13, the cover plate 14, and the second magnetic block 15, when it is necessary to maintain the internal structure of the fixing frame 4, the first magnetic block 13 and the second magnetic block 15 are separated by flipping the cover plate 14. When the cover plate 14 is flipped in the opposite direction, the second magnetic block 15 on the cover plate 14 will attract the first magnetic block 13. At this time, the cover plate 14 will not swing during the operation of the equipment, thus facilitating subsequent maintenance by the staff.

[0033] Working principle: First, the item is placed on the conveyor 3, which transports it to the bottom of the labeling machine body 2. During this process, two symmetrically distributed guide plates 9 on the conveyor 3 guide the item to be labeled, correcting any misalignment on the conveyor 3. The motor 5 drives the bidirectional threaded rod 6 to rotate, causing the threaded connecting sleeve 7 on the outer wall of the bidirectional threaded rod 6 to move the connecting frame 8 in opposite directions. One end of the connecting frame 8 then moves the two guide plates 9 together, thus labeling the two symmetrically distributed guide plates 9. The spacing of the guide plate 9 is adjusted to guide and correct items of different sizes, thereby improving the working efficiency of the online visual labeling machine. With the setting of the fixing block 12, the first magnetic block 13, the cover plate 14, and the second magnetic block 15, when it is necessary to maintain the internal structure of the fixing frame 4, the first magnetic block 13 and the second magnetic block 15 are separated by flipping the cover plate 14. When the cover plate 14 is flipped in the opposite direction, the second magnetic block 15 on the cover plate 14 will attract the first magnetic block 13. At this time, the cover plate 14 will not swing during the operation of the equipment, thus facilitating subsequent maintenance by the staff.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
