[0040] Reference Figures 1-6 An automatic labeling device for improving labeling accuracy includes a protective frame 1 and a support frame 4. The support frame 4 is fixedly connected to the top outer wall of the protective frame 1. The support frame 4 has a conveyor belt 2 for conveying products inside. A side plate 12 is fixedly connected to the top of the support frame 4. A top plate 3 is fixedly connected to the top outer wall of the side plate 12. A material-grabbing component 5 for adsorbing labels is provided on the top of the top plate 3. A transverse component 8 is provided at the bottom of the top plate 3. A label placement platform 6 is fixedly connected to the top outer wall of the support frame 4. A base frame 7 is fixedly connected to the bottom outer wall of the protective frame 1. A support column 13 is fixedly connected to the top outer wall of the support frame 4. The support column 13 is fixedly connected to the top plate 3, realizing accurate label pasting and effectively solving the problems of large positional deviation and easy label skew in traditional labeling.

[0041] Furthermore, the material handling component 5 includes an exhaust fan 5001 fixedly connected to the top outer wall of the top plate 3. A flexible hose 5003 is fixedly connected to one side of the exhaust fan 5001. A negative pressure suction cup 5002 is provided at one end of the flexible hose 5003. The bottom of the negative pressure suction cup 5002 has equally spaced suction holes. The exhaust fan 5001 forms a negative pressure zone at the bottom of the negative pressure suction cup 5002 through the flexible hose 5003. The evenly distributed suction holes generate suction force, which non-contactly adsorbs and fixes the labels placed on the table plate 6, avoiding damage to the label surface caused by mechanical clamping. It is suitable for ultra-thin and fragile labels (such as medical test strips) and supports high-speed material handling to ensure the stability of the production line cycle.

[0042] Furthermore, the transverse movement assembly 8 includes a first motor 8001 fixedly connected to the outer wall of one side of the side plate 12. The output end of the first motor 8001 is fixedly connected to a first threaded screw 8005. The outer circumferential wall of the first threaded screw 8005 is threadedly connected to a first threaded sleeve 8008. The first motor 8001 drives the first threaded screw 8005 to rotate, causing the first threaded sleeve 8008 to move along the screw axis. The sliding engagement between the guide post 8003 and the guide sleeve 8002 eliminates the radial vibration when the screw rotates. The vertical plate 8004 transmits the motion to the longitudinal movement assembly, which can effectively improve the positioning accuracy of the labeling head.

[0043] Furthermore, a guide post 8003 is fixedly connected to one outer wall of the side plate 12, and a guide cylinder 8002 is sleeved on the outer circumference of the guide post 8003. A vertical plate 8004 is fixedly connected to the bottom outer wall of the guide cylinder 8002. The end of the vertical plate 8004 away from the guide cylinder 8002 is fixedly connected to the first threaded sleeve 8008. A longitudinal movement component is provided at the bottom of the first threaded sleeve 8008. By sliding the guide cylinder 8002 on the outer wall of the guide post 8003, the wear of the first threaded screw 8005 can be effectively reduced, and the service life of the equipment can be extended.

[0044] Furthermore, the longitudinal movement assembly includes a housing 8006 fixedly connected to the bottom outer wall of the first threaded sleeve 8008. A second motor 8013 is fixedly connected to one side outer wall of the housing 8006. A second threaded screw 8012 is fixedly connected to the output end of the second motor 8013. A second threaded sleeve 8009 is threadedly connected to the outer circumference of the second threaded screw 8012. The second motor 8013 drives the second threaded screw 8012 to rotate, and the second threaded sleeve 8009 moves along the screw axial direction through threaded transmission.

[0045] Furthermore, a limiting groove 8010 is formed on one side of the outer wall of the housing 8006. A sliding rod is slidably connected inside the limiting groove 8010. One end of the sliding rod is fixedly connected to one side of the outer wall of the second threaded sleeve 8009, and a sliding plate 8011 is fixedly connected to the end of the sliding rod away from the second threaded sleeve 8009. By sliding the sliding rod on the inner wall of the limiting groove 8010, the wear of the second threaded screw 8012 can be effectively reduced, and the service life of the equipment can be extended.

[0046] Furthermore, an electric push rod 8007 is fixedly connected to one side of the slide plate 8011, and a circular plate 10 is fixedly connected to the output end of the electric push rod 8007. The negative pressure suction cup 5002 is fixedly connected to the outer wall of one side of the circular plate 10. By activating the electric push rod 8007, the height of the labeling head can be dynamically adjusted.

[0047] Furthermore, a high-speed camera 11 is fixedly connected to the bottom outer wall of the circular plate 10. The high-speed cameras 11 are distributed in a circular pattern at equal intervals on the bottom outer wall of the circular plate 10. The high-speed cameras 11 collect images of the product or labeling position, and the image processing algorithm identifies information such as the product outline. The deviation between the actual position and the preset labeling position is calculated, and then the first motor 8001, the second motor 8013 and the electric push rod 8007 are controlled to adjust the labeling position, so as to achieve precise label pasting and effectively solve the problems of large labeling position deviation and easy label skew in traditional labeling.

[0048] Working principle: During use, the operator uses a high-speed camera 11 to capture images of the product or labeling location. Image processing algorithms identify the product outline and other information, calculate the deviation between the actual position and the preset labeling position, and control the first motor 8001, the second motor 8013, and the electric push rod 8007 to start. The first motor 8001 drives the first threaded screw 8005 to rotate. Through the threaded connection between the first threaded screw 8005 and the first threaded sleeve 8008, the first threaded sleeve 8008 moves the housing 8006 along the X-axis to the designated location. Subsequently, the second motor 8013 starts, driving the second threaded... Rotating the lead screw 8012, through the threaded connection between the second threaded lead screw 8012 and the second threaded sleeve 8009, can drive the electric push rod 8007 and the negative pressure suction cup 5002 to move along the Z-axis until the label at the bottom of the negative pressure suction cup 5002 moves to the product to be pasted, thus achieving precise label pasting. At the same time, the high-speed camera 11 can identify objects of various shapes, colors and materials. Even if the object surface has certain textures, patterns or reflections, it can be accurately identified and located through appropriate image processing algorithms. It can also quickly switch detection modes and parameters according to different products or pasting tasks, and has strong versatility.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
