[0036] In order to make the technical objectives, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] The present invention provides a labeling machine 100. In order to clearly describe the technical solution of the present invention, the following is defined as follows: Figure 1 The XYZ directions in the figure constitute a spatial rectangular coordinate system, and the direction of the Z axis is the vertical direction or the up-down direction of the labeling machine 100.

[0040] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present invention, the labeling machine 100 includes a feeding module 110, a labeling head 120, a transmission limit assembly 130, a displacement module 140, a first camera module 150 and a second camera module 160;

[0041] The feeding module 110 is used to provide and peel off the labels attached to the adhesive tape;

[0042] The labeling head 120 is used to absorb the label;

[0043] The conveying and limiting assembly 130 is used to convey and fix the product to be labeled;

[0044] The first camera module 150 is used to shoot the label adsorbed on the labeling head 120 from bottom to top; the second camera module 160 is fixed to the labeling head 120 and is used to shoot the product to be labeled placed on the conveying limit assembly 130 from top to bottom;

[0045] The displacement module 140 includes a moving module that moves in the XYZ axis direction and a rotating module 142 that rotates around the Z axis;

[0046] The movable module is connected to the labeling head 120 via the rotating module 142 . The movable module is used to control the labeling position of the labeling head 120 . The rotating module 142 is used to control the labeling angle of the labeling head 120 .

[0047] It can be understood that the technical solution of the present invention is to set up a feeding module 110 for providing and peeling off labels attached to the adhesive tape; to set up a labeling head 120 for adsorbing labels; to set up a conveying limit assembly 130 for conveying and fixing the products to be labeled; to set up a first camera module 150 for photographing the labels adsorbed on the labeling head 120 from bottom to top; and to set up a second camera module 160, which is fixed to the labeling head 120 and is used to photograph the products to be labeled placed on the conveying limit assembly 130 from top to bottom. Specifically, the present invention also includes a displacement module 140, which comprises a mobile module that moves in the X, Y, and Z axes and a rotation module 142 that rotates about the Z axis. The mobile module is connected to the labeling head 120 via the rotation module 142, and is used to control the labeling position of the labeling head 120; the rotation module 142 is used to control the labeling angle of the labeling head 120. Optionally, after the first camera module 150 identifies the label on the labeling head 120, if the label is tilted, the rotation module 142 can be controlled to rotate to adjust the label's orientation. Alternatively, after the second camera module 160 identifies the product to be labeled on the conveyor stop assembly 130, if the product's position does not meet preset requirements, the specific displacement position of the label on the labeling head 120 can be adjusted by controlling both the mobile module and the rotation module 142. Therefore, the present invention improves the positioning accuracy of the labeling machine 100, thereby enhancing labeling quality.

[0048] It should also be emphasized that in actual production, the feeding module 110 is used to automatically peel off the label from the adhesive tape. The automatically peeled label placed on the feeding module 110 is likely to cause the feeding module 110 to be misplaced, which will cause the label applied to the labeled product by the labeling head 120 to be skewed, and the labeling quality to be unstable. In addition, those skilled in the art have also found that the conveying limit assembly 130 used to convey and fix the labeled product is usually in the form of a conveyor belt for loading and unloading the labeled product. After the product is loaded, if the conveyor belt stops, the labeled product will generate forward or backward inertia, which will cause the labeled product to be easily misplaced. Therefore, the technical solution of the utility model can be used to guide the displacement module 140 to adjust and change the position and direction of the label on the labeling head 120 by setting a first camera module 150 and a second camera module 160.

[0049] Optionally, the moving module that moves in the XYZ axis direction is a three-dimensional right-angle moving module.

[0050] Specifically, the moving modules in each of the XYZ directions are all screw rod and slide rail moving modules.

[0051] See also Figure 1 、 Figure 2 and Figure 3In a specific embodiment of the present invention, the Z-axis module in the mobile module is a belt-driven translation module;

[0052] The belt drive translation module includes a first belt drive assembly 1411 and a first mounting member 1412; the first belt drive assembly 1411 is connected to the driving portion of the X-axis module or the Y-axis module in the moving module; the belt of the first belt drive assembly 1411 is fixedly connected to the first mounting member 1412;

[0053] The rotating module 142 includes a second belt drive assembly 1421 and a guide post 1422 extending in the Z-axis direction. The guide post 1422 is fixedly connected to the first mounting member 1412 in the Z-axis direction and can rotate around the Z-axis relative to the first mounting member 1412. The second belt drive assembly 1421 is fixedly connected to the first belt drive assembly 1411.

[0054] In which, the guide column 1422 forms a limiting portion, and the limiting portion passes through the driven shaft of the second belt drive component 1421 and cooperates with the driven shaft of the second belt drive component 1421 to make the guide column 1422 and the driven shaft of the second belt drive component 1421 rotate synchronously; the guide column 1422 is used to connect the labeling machine head 120.

[0055] It is understood that the Z-axis module in the moving module of the labeling machine 100 does not require high movement accuracy during the labeling process. In addition, compared to some embodiments in which the Z-axis module is a screw-slide moving module, the belt-driven translation module in this embodiment is lighter.

[0056] Therefore, setting the Z-axis module in the mobile module as a belt-driven translation module can not only reduce the production cost of the labeling machine 100, but also improve the stability of the mobile module during operation.

[0057] Furthermore, in this embodiment, the second belt drive assembly 1421 is used as a part of the rotating module 142. Compared with a motor that requires a separate reducer, the arrangement of the rotating module 142 in this embodiment also reduces mass.

[0058] Furthermore, in this embodiment, the Z-axis module does not need to drive the rotating module 142 itself to move the labeling head 120. This reduces the energy consumption of the Z-axis module. Specifically, when the labeling head 120 moves up and down in the Z direction, the Z-axis module only needs to overcome the first mounting member 1412, the guide post 1422, and the labeling head 120 to perform work, and does not need to overcome the gravity of the second belt drive assembly 1421 itself.

[0059] It should also be noted that in this embodiment, both the first belt drive assembly 1411 and the second belt drive assembly 1421 are composed of a motor and a belt, and the motor is capable of driving the belt to perform a belt transmission. Specifically, the first belt drive assembly 1411 is used to generate work by the belt in the Z-axis direction; the second belt drive assembly 1421 is used to transfer the work generated by the motor on the driving pulley to the driven pulley via the belt, and the rotation of the driven pulley is used to generate work for the guide column 1422.

[0060] Optionally, the guide post 1422 has a D-shaped cross section, and the limiting portion is a flat surface on the guide post 1422. Thus, when the limiting portion engages with the driven wheel on the second belt drive assembly 1421, the guide post 1422 can rotate synchronously with the driven wheel, and the post can move relative to the driven wheel in the Z-axis direction.

[0061] Optionally, the labeling head 120 is further provided with a suction cup 121, and the suction cup 121 is used to absorb and release the label.

[0062] See also Figure 1 and Figure 4 In a specific embodiment of the present invention, the conveying limiting assembly 130 includes a first conveyor belt 131, a first cylinder 132, and a second cylinder 133. The first cylinder 132 is used to limit the position of the labeled product in the conveying direction of the first conveyor belt 131, and the second cylinder 133 is used to position the labeled product in the width direction of the first conveyor belt 131, thereby fixing the labeled product.

[0063] Please continue reading Figure 4 In one embodiment, the conveyor stop assembly 130 further includes a third cylinder 134, which is also used to limit the position of the labeled product in the conveyor belt's conveying direction. The first cylinder 132 and the third cylinder 134 are located on either side of the labeled product. It is understood that the third cylinder 134 serves the same purpose as the first cylinder 132. When the first and third cylinders 132 and 134 need to swap the loading and unloading stations of the labeler, only the conveying direction of the first conveyor belt 131 needs to be changed; no other configuration is required, easily meeting user requirements.

[0064] It should also be noted that, during the actual operation of the labeling machine 100 , only one of the first cylinder 132 and the third cylinder 134 can be selected.

[0065] Optionally, the conveying limiting assembly 130 further includes a second conveyor belt 135 , and the first conveyor belt 131 and the second conveyor belt 135 are arranged in the same horizontal direction for conveying on the same assembly line.

[0066] Optionally, the conveying limiting assembly 130 further includes a third cylinder 134 and a fourth cylinder; the third cylinder 134 is used to limit the labeled product in the conveying direction of the second conveyor belt 135, and the fourth cylinder is used to position the labeled product in the width direction of the second conveyor belt 135.

[0067] It is understandable that the third cylinder 134 and the fourth cylinder have the same purpose as the first cylinder 132 and the second cylinder 133 , and therefore are not shown in the drawings.

[0068] like Figure 1 As shown, at least two feeding modules 110 are included in the X-axis direction or the Y-axis direction.

[0069] It can be understood that label rolls can be placed on the two feeding modules 110 respectively. After one of the label rolls is used up, the labeling head 120 can be directly controlled to use the label on the other feeding module 110, thereby realizing non-stop labeling and improving the utilization efficiency of the labeling machine 100.

[0070] Alternatively, as Figure 1 As shown, two feeding modules 110 are provided in both the X-axis direction and the Y-axis direction, and a total of four feeding modules 110 are provided on one labeling module. In actual use, the four feeding modules 110 can be used to place the same label roll or different label rolls to achieve non-stop labeling.

[0071] It should also be noted that in the technical solution of the present utility model, the feeding module 110 is a prior art and therefore will not be described in detail here. Figure 5 , Figure 5 1 is a structural diagram of the feeding module 110 of the present invention. The feeding module 110 in the embodiment of the present invention is also referred to as a feeder feeder or a feeding module 110 group by those skilled in the art.

[0072] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
