Abstract

A labeling device, comprising a scale control assembly ( 11 ) and a stripping assembly ( 12 ), the scale control assembly ( 11 ) being configured to obtain a material strip ( 10 ) and to lead out a predetermined length of the material strip ( 10 ); the stripping assembly ( 12 ) being configured to grasp a target label ( 101 ) on the material strip ( 10 ) led out by the scale control assembly ( 11 ) and to affix the target label ( 101 ) to a product (D) to be labeled at a pre-set position so as to obtain a labeled product. Said device controls, by means of the scale control assembly, the length of the material strip that is led out at each time when labeling the product to be labeled, so as to improve the precision of the stripping assembly grasping the label and affixing the label to the product to be labeled.

First claim

1 . A labeling device, comprising a scale control component and a stripping component; wherein,
the scale control component is configured to acquire a tape, and to export the tape at a predetermined length; the stripping component is configured to grab a target label on the tape exported from the scale control component and to attach the target label onto a product to be labeled which is located at a preset position, so as to obtain a labeled product.

2 . The labeling device according to claim 1 , wherein the tape is provided with a plurality of equally spaced labels, and a length L of the tape exported from the scale control component satisfies H+K23 L≦H+2K, where K is a space between the labels, and H is a length of the label.

3 . The labeling device according to claim 1 , further comprising a feeding component and a receiving component, wherein,
the feeding component is configured to initially store the tape; the receiving component is configured to pull out and receive the tape exported from the feeding component; wherein the scale control component, the stripping component, the feeding component and the receiving component are arranged such that: the tape exported from the feeding component as driven by the receiving component is received by the receiving component only upon running through the scale control component and through the stripping component.

4 . The labeling device according to claim 1 , wherein the feeding component is a wheel, and the receiving component is a motor-driven wheel.

5 . The labeling device according to claim 2 , wherein the scale control component comprises a fixing member, a moving member and a label sensor, and
the labeling device further comprises a scale control module electrically connected with the scale control component, wherein the moving member is movably connected with the fixing member; the moving member is configured to clamp the tape, and to move on the fixing member as driven by the tape; the label sensor is configured to sense a spacing region between the labels on the tape; the scale control module is configured to, upon the label sensor sensing the spacing region ahead of the target label on the tape, control the moving member to clamp the tape and to be moved from an initial position for a preset distance as driven by the tape and then stop, so as to limit a movement of the tape; and the scale control module is further configured to, upon the stripping component attaching the target label onto to the product to be labeled, control the moving member to return to the initial position, wherein the preset distance is equal to the length L of the tape exported from the scale control component; the spacing region is a region between adjacent labels on the tape; and 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.

6 . The labeling device according to claim 1 , wherein the stripping component comprises an attaching cylinder and a moving cylinder, and
the labeling device further comprises a stripping control module electrically connected with the stripping component, wherein the attaching cylinder is provided with a stripping attaching rod, the stripping attaching rod is configured to move along a length direction of the stripping attaching rod, and is configured to strip the target label off the tape and attach the target label onto the product to be labeled; the moving cylinder is provided with a stripping platform, the stripping platform is configured to move between a stripping position and a standby position as driven by the moving cylinder; and the stripping control module is configured to, upon the stripping platform being in the stripping position and the target label having moved with the tape to the stripping platform, control the stripping attaching rod to grab the target label; and the stripping control module is further configured to, upon the stripping attaching rod grabbing the target label, control the stripping platform to move to the standby position and control the stripping attaching rod to stretch out, so as to attach the target label onto the product to be labeled.

7 . The labeling device according to claim 6 , further comprising a compression component, the compression component comprises a compression cylinder and a compression platform, and the compression component is configured to acquire the tape exported from the scale control component and guide the tape to the stripping component, wherein,
the compression cylinder is provided with a compression rod, and the compression rod is configured to tightly press the tape which has moved to the compression platform, as driven by the compression cylinder.

8 . The labeling device according to claim 7 , wherein,
the compression platform is further provided with a flattening plate, the flattening plate is configured to press against the tape, so that the tape moves on the compression platform in a manner of attaching to the compression platform.

9 . The labeling device according to claim 1 , further comprising a product placement component, wherein,
the product placement component comprises a base and at least two product placement platforms connected therewith, and every product placement platform is configured to allow a product to be labeled to be placed thereon, and is configured to move the product to be labeled to the preset position, as driven by the base, in sequence.

10 . The labeling device according to claim 9 , wherein,
the at least two product placement platforms are arranged in a circumferential array with a center of the base as a circle center, and the base is capable of rotating and driving the at least two product placement platforms to circumferentially move with the center of the base as the circle center.

11 . The labeling device according to claim 9 , further comprising a labeling inspection component,
the labeling inspection component is configured to acquire an image of the labeled product located at an inspection position, and configured to determine whether the label on the labeled product satisfies a preset attachment precision or not according to the image; wherein every product placement platform, upon moving to the preset position as driven by the base, is capable of further moving to the inspection position as driven by the base.

12 . The labeling device according to claim 11 , wherein the labeling inspection component comprises a camera configured to acquire the image of the labeled product located at the inspection position.

13 . The labeling device according to claim 12 , wherein the labeling inspection component further comprises a magnifying glass with a light source, and
the magnifying glass with the light source is disposed between the camera and the inspection position.
