     DETAILED DESCRIPTION 
       [0027]    Hereafter, the technical solutions in the embodiments of the present disclosure will be described in a clearly and fully understandable way in connection with the drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are just a part but not all of the embodiments of the disclosure. Based on the described embodiments herein, one person skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the disclosure. 
         [0028]    Unless otherwise defined, the technical terminology or scientific terminology used herein should have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Likewise, terms like “first,” “second,” etc., which are used in the description and the claims of the present application for invention, are not intended to indicate any sequence, amount or importance, but distinguish various components. The phrases “connect”, “connected”, etc., are not intended to define a physical connection or mechanical connection, but may include an electrical connection, directly or indirectly. “On,” “under,” “left,” “right” or the like is only used to describe a relative positional relationship, and when the absolute position of a described object is changed, the relative positional relationship might also be changed accordingly. 
         [0029]      FIG. 1  is a schematic diagram illustrating a labeling device provided by an embodiment of the present disclosure. As illustrated in  FIG. 1 , the labeling device may include a scale control component  11  and a stripping component  12 . The scale control component  11  is configured to acquire a tape, and configured to control a length of the tape as acquired and then export the tape at a controlled length; that is, the tape with a predetermined length. The stripping component  12  is configured to grab a target label on the tape exported from the scale control component  11 , and attach the target label on a product D to be labeled which is located at a preset position, so as to acquire a labeled product. 
         [0030]    As described above, in the labeling device provided by the embodiment of the present disclosure, every time when the label is attached to the product to be labeled, the length of the tape as exported is controlled by the scale control component, so as to increase the precision for the stripping component to grab the label and to attach the label onto the product to be labeled. In this way, it solves the problem that using a known labeling pressing fixture to attach the label onto the product involves lower precision, and achieves technical effect of improving the labeling precision. 
         [0031]      FIG. 2A  illustrates a structure of another labeling device provided by an embodiment of the present disclosure. As compared with the labeling device illustrated in  FIG. 1 , an additional component is included in the labeling device provide by the present embodiment to achieve better performance. 
         [0032]    As illustrated in  FIG. 2A , the labeling device may further include a feeding component  13  and a receiving component  14 . The feeding component  13  is configured to initially store the tape. For example, the feeding component  13  may be implemented as a wheel, and the tape may wind round the wheel or gradually extend as the rotation of the wheel. The receiving component  14  is configured to pull out the tape from the feeding component  13  and receive the tape. For example, the receiving component  14  may be implemented as a wheel with a driver. Exemplarily, the receiving component  14  may be driven by a stepper motor. 
         [0033]    According to the technical solution of the present embodiment, as driven by the receiving component  14 , the tape is exported from the feeding component  13 , passing through the scale control component  11  and the stripping component  12 , and is finally received by the receiving component  14 . For example, with a driven rotation of the receiving component  14  in a form of wheel, the tape that is initially wound on the feeding component  13  in a form of wheel will gradually leave the feeding component  13  under a pulling force, and finally be wound on the receiving component  14  to implement the above-described “receiving”. Here, a positional relationship among the feeding component  13 , the scale control component  11 , the stripping component  12  and the receiving component  14  is not limited in any way, as long as the tape exported from the feeding component  13  as driven by the receiving component  14  runs through the scale control component  11  and the stripping component  12  before it&#39;s received by the receiving component  14 . 
         [0034]      FIG. 2B  is a schematic diagram illustrating a structure of the scale control component  11  of the labeling device illustrated in  FIG. 2A . The scale control component  11  includes a fixing member  111 , a moving member  112  and a label sensor  113 , wherein the moving member  112  is movably connected with the fixing member  111 . The moving member  112  is configured to clamp, for example, the tape  10  exported from the feeding component  13  as driven by the receiving component  14 , and to move on the fixing member  111  as driven by the tape  10 . Although  FIG. 2B  illustrates a case where the moving member  112  moves along a curve, taken Z as an axis, driven by the tape  10 , yet the moving member  112  may also move linearly as driven by the tape  10 , without particularly limited by the embodiments of the present disclosure. 
         [0035]    In one example, the labeling device further includes a label sensor  113  and a scale control module electrically connected with the scale control component  11 . The label sensor  113  is configured to sense a spacing region j between labels  101  on the tape  10 ; the tape  10  is provided with a plurality of equally spaced labels  101 , and a region between adjacent two labels  101  is just the spacing region. Exemplarily, the label sensor  113  may sense the spacing region j by a height difference on the tape  10 . The scale control module is configured to, when the label sensor  113  senses the spacing region ahead of the target label on the tape  10 , control the moving member  112  to clamp the tape  10 , so that the moving member  112  is driven by the tape  10  to move from an initial position by a preset distance and then stop, so as to limit the movement of the tape  10 ; the scale control module is further configured to, after the stripping component  12  attaches the target label onto to the product to be labeled, control the moving member  112  to return to the initial position, wherein the target label is any label on the tape  10 ; the preset distance is equal to a length L of the tape desired to be exported from the scale control component  11 , and L satisfies: H+K≦L≦H+2K, where, K is a space between the labels  101  on the tape  10 , and H is a length of the label. The spacing region ahead of the target label is one of the spacing regions on both ends of the target label, which is more forward along a moving direction. 
         [0036]    Every time when attaching a label onto a product to be labeled by using the labeling device provided by the embodiment of the present disclosure, a series of same labeling actions need to be completed; and the scale control component  11  is arranged to ensure a length of the exported tape for labeling is consistent given that the same tape is used. 
         [0037]    In addition, the operator may further adjust the length L of the exported tape by the scale control component  11 , so that the labeling device provided by the embodiment of the present disclosure can precisely attach labels on different tapes (a size of the label or a space between adjacent labels on different tapes may be different) onto the product to be labeled. 
         [0038]    Still, as illustrated in  FIG. 2A , the stripping component  12  includes an attaching cylinder  121  and a moving cylinder  122 . The attaching cylinder  121  is provided with a stripping attaching rod  121   a,  the stripping attaching rod  121   a  can move along a length direction a of the stripping attaching rod  121   a,  and the stripping attaching rod  121   a  is configured to strip a target label off the tape and attach the target label onto the product D to be labeled. The moving cylinder  122  is provided with a stripping platform  122   a,  and the stripping platform  122   a  is capable of moving between a stripping position and a standby position as driven by the moving cylinder  122 .  FIG. 2A  illustrates the stripping platform  122   a  located at the stripping position b; and  FIG. 2C  illustrates the stripping platform  122   a  located at the standby position c. Other reference signs in  FIG. 2C  indicate the same with those in  FIG. 2A . 
         [0039]    In one example, the labeling device further includes a stripping control module electrically connected with the stripping component  12 . The stripping control module is configured to, when the stripping platform  122   a  is in the stripping position and the target label moves with the tape to the stripping platform  122   a,  control the stripping attaching rod  121   a  to grab the target label; and the stripping control module is further configured to, after the stripping attaching rod  121   a  grabs the target label, control the stripping platform  122   a  to move to the standby position and control the stripping attaching rod  121   a  to stretch out so as to attach the target label onto the product to be labeled. 
         [0040]    It should be noted that, the scale control module and the stripping control module involved in the embodiments of the present disclosure may be implemented as one or more processors for controlling operation of the labeling device provided by the embodiment of the present disclosure. 
         [0041]    In one example, as illustrated in  FIG. 2A , the labeling device further includes a compression component  15 , the compression component  15  includes a compression cylinder  151  and a compression platform  152 ; and the compression component  15  is configured to acquire the tape exported from the scale control component  11 , and guide the tape to the stripping component  12 . Although the compression platform  152  illustrated in  FIG. 2A  is constituted by an upper portion of the moving cylinder  122 , the compression platform  152  may also be provided separately, without particularly limited in the embodiments of the present disclosure. The compression cylinder  151   a  is provided with a compression rod  151   a , and the compression rod  151   a  is capable of tightly pressing the tape which has been moved onto the pressing platform  152  as driven by the pressing cylinder  151 , so as to limit the movement of the tape. 
         [0042]    In one example, as illustrated in  FIG. 2A , the compression platform  152  is further provided with a flattening plate  152 , the flattening plate  152   a  is configured to press against the tape, so that the tape on the compression platform  152  can move along the compression platform  152  in a manner of attaching to the compression platform  152 . The flattening plate  152   a  may be made of an elastic material, so that the tape can well move when pressed against the compression platform  152 . 
         [0043]    In one example, as illustrated in  FIG. 2A , the labeling device further includes a product placement component  16 . 
         [0044]    The product placement component  16  includes a base  161  and at least two product placement platforms  162  connected therewith; every product placement platform  162  may be sequentially moved to a preset position y as driven by the base  161 ; and the product placement platform  162  allows the product D to be placed thereon. By arranging the at least two product placement platforms  162 , the labeling device, after completing labeling one product to be labeled, can immediately label a next product to be labeled, which improves the working efficiency of the labeling device. 
         [0045]    In one example, the at least two product placement platforms  162  are arranged in a circumferential array with a center of the base  161  as a circle center, and the base  161  is capable of rotating and driving the at least two product placement platforms  162  to circumferentially move with the center of the base  161  as the circle center.  FIG. 2D  is a top view of the product placement component  16  illustrated in  FIG. 2A . As illustrated in  FIG. 2D , the two product placement platforms  162  circumferentially move with a center g of the base  161  as the circle center. Of course, the number of the product placement platforms  162  is not limited to two as illustrated in  FIG. 2A  and  FIG. 2D , but can be set by those skilled in the art according to actual needs. 
         [0046]    In one example, as illustrated in  FIG. 2A , the labeling device further includes a labeling inspection component  17 . The labeling inspection component  17  is capable of acquiring an image of a labeled product located at an inspection position p, and determining whether the label on the labeled product (the product to be labeled having the labeling completed) satisfies a preset attachment precision or not according to the image as acquired. For example, the inspection position p may be a position where the product placement platform  162  places the labeled product. For example, every product placement platform  162 , after moving to the preset position as driven by the base  161 , can further move to the above-described inspection position p as driven by the base  161 . For example, the labeling inspection component  17  may include a camera  171  to acquire the image of the labeled product located at the inspection position p. 
         [0047]    In one example, the labeling inspection component  17  further includes a magnifying glass  172  with a light source, and the magnifying glass  172  with the light source may be disposed between the camera  171  and the inspection position p. The magnifying glass  172  with the light source may assist the camera  171  to acquire the image of the labeled product, and improve sharpness and brightness of the image. 
         [0048]      FIG. 2E  is a structural schematic diagram illustrating the operation of the labeling device provided by the embodiment of the present disclosure. As illustrated in  FIG. 2E , after exported from the feeding component  13 , the tape  10  enters the scale control component  11 , then is exported from the scale control component  11  and runs through the compression platform  152  and the stripping platform  122   a,  and finally enters the receiving component  14 . 
         [0049]    It should be additionally noted that, in the labeling device provided by the embodiment of the present disclosure, with the stripping platform capable of moving between the stripping position and the standby position as driven by the moving cylinder, it allows the stripping attaching rod to complete actions of grabbing the label and attaching the label only by a movement in the length direction thereof, which improves the precision of the label attaching process. The labeling device provided by the embodiment of the present disclosure has a higher degree of automation, can automatically complete labeling without manual operation, and can control the position of the label by the scale control component, so that the labeling device is capable of precisely attaching labels of different sizes onto the product to be labeled, which improves the applicability of the labeling device. 
         [0050]    It should be additionally noted that, in the labeling device provided by the embodiment of the present disclosure, with the camera, the image of the labeled product in the inspection position is acquired, which achieves a technical effect of inspecting an attachment status of the label on the labeled product. 
         [0051]    It should be additionally noted that, in the labeling device provided by the embodiment of the present disclosure, with the at least two product placement platforms, it is possible to continuously attach labels onto products to be labeled, which achieves a technical effect of improving the working efficiency of the labeling device. 
         [0052]    It should be additionally noted that, in the labeling device provided by the embodiment of the present disclosure, with the compression component, it is possible to tightly press the tape when the attaching platform moves, so that the movement of the compression component will not affect the position of the tape, which improves the precision of label positioning. 
         [0053]    In summary, in the labeling device provided by the embodiment of the present disclosure, every time when the label is attached onto the product to be labeled, the length of the tape as exported is controlled by the scale control component so as to increase the precision for the stripping component to grab the label and to attach the label onto the product to be labeled, which solves the problem of lower labeling precision in the prior art in which a labeling compression fixture is used for attaching the label onto the product, and achieves a technical effect of improving the labeling precision. 
         [0054]    The above merely are specific embodiments of the present disclosure, but not intended to define the scope of the present disclosure. Any variations or replacements capable of being easily thought by those skilled in the art shall fall within the scope of the present disclosure. Thus, the scope of the disclosure shall be determined by the scope of the claims.
