[0046] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0047] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0048] To simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0049] In this document, "one" not only means "only one," but can also mean "more than one." In this document, "first," "second," and so on are used solely to distinguish one from another, not to indicate their importance or order. For ease of explanation, in this disclosure, the opening on the nozzle for sucking the label 70 and the opening on the air nozzle for ejecting air are referred to as operating openings.

[0050] Figure 1a 、 Figure 1b Schematic diagrams of a label are shown respectively. Figure 1a and Figure 1b As shown, label 70 includes an adhesive portion 71, a waste portion 72, and a cutout 73. Adhesive portion 71 is used to be attached to a product to identify the product's serial number, batch code, and other information. The shape of adhesive portion 71 is designed based on the shape of the corresponding product. Cutout 73 is used to separate adhesive portion 71 from waste portion 72. Cutout 73 can be a continuous closed line as shown in the figure, or it can be provided with breakpoints on the closed line. When cutout 73 is designed as a continuous closed line, after the separator paper is removed, adhesive portion 71 and waste portion 72 are held together by the adhesive material attached to label 70. When cutout 73 is designed with breakpoints, after the separator paper is removed, adhesive portion 71 and waste portion 72 are held together by the breakpoints and the adhesive material attached to label 70. Adhesive portion 71 can also be provided with a non-adhesive portion 74, which is not provided with adhesive material. After the adhesive portion 71 is adhered to the product, the adhesive portion 71 can be torn off the product through the non-adhesive portion 74 .

[0051] Figure 2 A schematic structural diagram for illustrating the labeling device of the present invention. Figure 3 for Figure 2 A structural diagram from another perspective. The labeling device is used to attach a label 70.

[0052] like Figure 2 As shown, the labeling device includes a bracket 10, on which a rotary cylinder 20 is mounted. The rotary cylinder 20 comprises a rotary base 21, a cylinder body 22, and a cylinder push rod 23. The cylinder body 22 is connected to the rotary base 21 and can rotate relative to the rotary base 21. The cylinder push rod 23 is mounted on the cylinder body 22 and can reciprocate relative to the cylinder body 22.

[0053] The rotary cylinder 20 is further provided with a pusher 231, a first suction nozzle 41, and an air nozzle 43. The first suction nozzle 41 and the air nozzle 43 are provided on the cylinder body 22 and are stationary relative to the cylinder body 22. The pusher 231 is provided at the end of the cylinder push rod 23 away from the cylinder body 22 and can reciprocate with the cylinder push rod 23 relative to the cylinder body 22.

[0054] When the labeling device is operating, the rotating cylinder 20 first picks up a label 70 from the label receiving area. Specifically, the rotating cylinder 20 uses the first suction nozzle 41 to absorb the waste portion 72 of the label 70. Then, the cylinder body 22 rotates a certain angle, driving the label 70 to rotate and adjust the label 70 to the desired orientation. Next, the pusher 231 moves toward the label 70, pushing the adhesive portion 71 away from the waste portion 72. It then pushes the adhesive portion 71 onto the product to adhere it. Finally, the air nozzle 43 located near the waste portion 72 emits air to blow the waste portion 72 away from the rotating cylinder 20.

[0055] The end of the suction nozzle of the labeling device away from the operation port is connected to a vacuum generator through a pipeline; the end of the air nozzle of the labeling device away from the operation port is connected to an air source through a pipeline. Figure 2 and Figure 3 The aforementioned pipeline is not shown in the figure. A solenoid valve can be provided on the pipeline to control the suction of the suction nozzle and the ejection of the air nozzle.

[0056] Since there is a certain distance between the label acquisition location and the product location, in order to move the label 70 to the product location, the rotary cylinder 20 needs to be able to move a certain distance. Therefore, a first rodless cylinder 30 can be further provided in the labeling device. Specifically, Figure 2 and Figure 3 As shown in , a first rodless cylinder 30 may also be provided on the bracket 10. The first rodless cylinder 30 includes a first slide rail 31 and a first sliding body 32. The first sliding body 32 can slide on the first slide rail 31. The rotating base 21 of the rotary cylinder 20 is fixedly connected to the first sliding body 32. The sliding direction of the first sliding body 32 is parallel to the reciprocating direction of the cylinder push rod 23. When performing the labeling operation, the first sliding body 32 of the first rodless cylinder 30 drives the cylinder body 22 close to the label acquisition position to pick up the label. After acquiring the label, the first sliding body 32 of the first rodless cylinder 30 drives the cylinder body 22 away from the label acquisition position and moves to a position close to the product. Before, after or during the movement of the first sliding body 32, the rotary cylinder 20 can be set to drive the label to rotate.

[0057] In order to support the labeling device to simultaneously support the labeling of products from different production lines or different stages, another working position can be set. Therefore, a product carrier 60 and a second rodless cylinder 50 that cooperates with the product carrier 60 can be set on the labeling device.

[0058] like Figure 2 and Figure 3As shown, a second rodless cylinder 50 and a product carrier 60 are also provided on the bracket 10 of the labeling device. The second rodless cylinder 50 includes a second slide rail 51 and a second sliding body 52. The product carrier 60 is provided on the second sliding body 52, and the second sliding body 52 can drive the product carrier 60 to slide on the second slide rail 51. The sliding direction of the second sliding body 52 can be designed to be perpendicular to the sliding direction of the first sliding body 32. When the labeling device is working, after a manual or robotic arm places the product on the product carrier 60, the second sliding body 52 drives the product carrier 60 and the product on the product carrier 60 to slide along the second slide rail 51 toward the rotating cylinder 20; when the product carrier 60 slides to the pasting position, after the cylinder body 22 rotates a preset angle, the end of the cylinder push rod 23 is opposite to the position of the product carrier 60. As shown Figure 2 and Figure 3 As shown, the rotary cylinder 20 can drive the label to rotate 90 degrees clockwise so that the label 70 faces the product on the product carrier 60. The rotary cylinder 20 can also drive the label to rotate 90 degrees counterclockwise so that the label 70 faces the product above it.

[0059] To facilitate maintaining the relative stillness of the first suction nozzle 41, the air nozzle 43, and the cylinder body 22, and to simplify the structural design, the rotary cylinder 20 may further include a mounting base 40. The mounting base 40 is fixedly connected to the cylinder body 22; the first suction nozzle 41 and the air nozzle 43 are fixedly connected to the mounting base 40. The mounting base 40 may also be provided with an opening 44 through which the cylinder push rod 23 can pass.

[0060] Figure 4 Schematic diagram for illustrating the suction nozzle and air nozzle of the labeling device of the present invention. Figure 4 The first suction nozzle 41 , the air nozzle 43 and the pushing portion 231 are shown.

[0061] When the pushing portion 231 pushes the sticking portion 71 to separate from the waste portion 72, it is necessary to prevent the sticking portion 71 from separating from the pushing portion 231 or from moving relative to the pushing portion 231. Therefore, a second suction nozzle can be further provided on the pushing portion 231. When the pushing portion 231 pushes the sticking portion 71 to separate from the waste portion 72, the second suction nozzle aligns with the sticking portion 71 and can hold the sticking portion 71 in place. The second suction nozzle can have the same structure as the first suction nozzle.

[0062] When the pushing portion 231 pushes the pasting portion 71 to separate it from the waste portion 72, in order to ensure the separation effect, it is advisable to set two first suction nozzles 41 to absorb the waste portion 72. Therefore, the number of first suction nozzles 41 can be designed to be two. Taking into account that different products correspond to different label style designs, in order to enable the labeling device to be applicable to various styles of labels, the number of first suction nozzles 41 can be designed to be more than two. When a label 70 is adsorbed on the rotating cylinder 20, at least two of the first suction nozzles 41 absorb the waste portion 72. Therefore, for different styles of labels, two of the first suction nozzles 41 corresponding to the style can be selected according to the style of the label.

[0063] also, Figure 4 A third suction nozzle 42 may be further provided on the mounting base 40. When a label 70 is attached to the rotating cylinder 20, the position of the third suction nozzle 42 corresponds to the position of the adhesive portion 71 and is used to attract the adhesive portion 71. The provision of the third suction nozzle 42 improves the reliability of the adhesive portion 71 when picking up the label. The air outlet of the air nozzle 43 can be designed to form an angle with the air intake direction of the first suction nozzle 41 to facilitate blowing away the waste portion 72.

[0064] The nozzles of the labeling device, such as the first nozzle 41, the second nozzle, and the third nozzle 42 mentioned above, can be used as follows: Figure 2 and Figure 3 The structural design shown. The suction nozzle includes a tubular structure, a second annular structure, a compression spring and a suction cup. One end of the tubular structure is mounted on the rotating cylinder 20 and is provided with an interface, and a first annular structure coaxial therewith is also fixedly provided on the tubular structure. The second annular structure is sleeved on the tubular structure and can slide relative to the tubular structure. One end of the compression spring abuts against the first annular structure, and the other end can support the second annular structure. The suction cup is sleeved on the other end of the tubular structure and wraps the other end, and the suction cup can compress the compression spring through the second annular structure. By providing the above-mentioned air nozzle with a buffer structure, it is possible to avoid the air nozzle from damaging the product when sticking labels.
