Detailed Description
The embodiment of the invention provides an antenna and a reader, which are used for solving the technical problem that the orientation requirement of a method for reading label information in the prior art on the label information is high.
In order to solve the technical problems, the technical scheme in the embodiment of the invention has the following general idea:
the sub-components of the antenna form a closed loop, and the sub-components respectively arranged on the two sides of the conveying belt and the bearing surface of the conveying belt form an included angle which is not zero and is not 90 degrees, namely the sub-components are obliquely arranged, so when an article or an animal with a label passes through the conveying belt, the label can be read by the magnetic field provided by the antenna in the embodiment no matter whether the label is attached above or below the article or attached in front of or behind the article, and therefore the requirement of the antenna on the orientation of the label in the embodiment of the invention is low, and the reading of label information is facilitated.
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
Referring to fig. 1 and fig. 2a to 2e, fig. 1 is a front view of an antenna according to an embodiment of the present invention. Fig. 2 a-2 e are top and side views, respectively, of the antenna of fig. 1.
As shown in fig. 1, 2 a-2 e, the antenna comprises: a first subcomponent 1, a second subcomponent 2, and a third subcomponent 3.
The first sub-component 1 is arranged on one side of a conveying belt and has a first included angle which is not zero with the bearing surface of the conveying belt. The first angle is for example angle alpha in fig. 2 e.
And the second sub-component 2 is arranged on the other side of the conveying belt and forms a second included angle which is not zero with the bearing surface. The second angle is for example angle alpha in fig. 2 e.
It should be noted that, in the example of fig. 2e, the first sub-assembly 1 and the second sub-assembly 2 are axially symmetrically distributed along the transmission belt, so the first included angle and the second included angle are the same, but in practical applications, the positions of the first sub-assembly 1 and the second sub-assembly 2 relative to the transmission belt may not be symmetrical, that is, the first sub-assembly 1 is disposed on the oblique opposite side of the second sub-assembly 2, and in this case, the first included angle and the second included angle may be the same or different. When the position is asymmetric, the antenna in this embodiment can also read the tags on both sides.
The third sub-component 3 is arranged above and/or below the bearing surface; the first sub-component 1, the second sub-component 2 and the third sub-component 3 form a closed loop for reading the tag information.
Optionally, in fig. 1, the third sub-element 3 is disposed above and below the bearing surface, and in practical applications, the third sub-element 3 may have only a portion above the bearing surface or only a portion below the bearing surface, so that the shape of the formed closed loop is a triangle or a sector.
Alternatively, in practical applications, the shape of the closed loop may be a polygon, a circle or an ellipse, or may be other shapes as long as the sub-components on both sides of the conveyor belt are inclined to the carrying surface.
Alternatively, the polygon may be a triangle or a rectangle.
Alternatively, the antenna formed by the first sub-assembly 1, the second sub-assembly 2 and the third sub-assembly 3 can be referred to as a doorframe-type antenna.
Alternatively, the tag may be a bar code, a two-dimensional code or a Radio Frequency Identification (RFID) tag attached to an article or an animal.
Correspondingly, the closed loop formed by the first sub-component 1, the second sub-component 2 and the third sub-component 3 can be used for identifying a bar code, a two-dimensional code or an RFID tag.
Optionally, the antenna in the present invention may be an antenna of a reader, and the reader obtains the tag information through the antenna and further processes the tag information.
As can be seen from the above description, the sub-components of the antenna form a closed loop, when the included angle between the sub-components disposed on both sides of the transmission belt and the bearing surface of the transmission belt is 90 degrees, the antenna can read the tags in the front and the back of the transmission direction, and there is an included angle between the sub-components disposed on both sides of the transmission belt and the bearing surface of the transmission belt that is not zero and not 90 degrees, that is, the antenna is disposed in an inclined manner, so that when an article or an animal with a tag passes through the transmission belt, the tag can be read by the magnetic field provided by the antenna in this embodiment, regardless of whether the tag is attached above or below the article, or attached in front of or behind the article.
Alternatively, in the example shown in fig. 2a and 2d, the first angle and the second angle are 90 degrees, i.e. the first sub-member 1 and the second sub-member 2 are perpendicular to the bearing surface, and the third sub-member 3 is parallel to the bearing surface. Further, the first sub-assembly 1 and the second sub-assembly 2 are axially symmetrically distributed along the conveyor belt. Thus, in the top view shown in fig. 2a, it can be seen that the third sub-member 3 is perpendicular to the boundary of the conveyor belt.
Alternatively, in the example shown in fig. 2b, the first included angle and the second included angle are 90 degrees, i.e. the first sub-element 1 and the second sub-element 2 are perpendicular to the bearing surface, and the third sub-element 3 is parallel to the bearing surface. The first sub-section 1 and the second sub-section 2 are not axially symmetrically distributed along the conveyor belt. Thus, it can be seen in the top view shown in fig. 2b that the third sub-member 3 is not perpendicular to the boundary of the conveyor belt.
Alternatively, in the example shown in fig. 2c and 2e, the first and second angles are greater than 90 degrees, the first and second sub-members 1, 2 are axisymmetrically distributed along the belt, and the third sub-member 3 is parallel to the carrying surface. As shown in fig. 2c and fig. 2e, when an article passes through the antenna in this embodiment, the antenna can read the tag t1 and the tag opposite to the tag t1, and can also read the tag t2 and the tag opposite to the tag.
Therefore, in the antenna of the present embodiment, because the included angle between the bearing surface and the first sub-assembly 1 and the second sub-assembly 2 is not 90 degrees, the antenna can read the tags on the upper surface and the lower surface.
Optionally, the third sub-element 3 is parallel to the bearing surface. In practical applications, the third sub-element 3 and the carrying surface may not be parallel.
Optionally, the first sub-element 1, the second sub-element 2 and the third sub-element 3 form a closed loop, which can rotate on a plane perpendicular to the bearing plane by using the third sub-element 3 as an axis, wherein the rotation angle is less than 180 degrees.
For example, please refer to fig. 2f and fig. 2g, which are a side view and a top view of the closed loop formed by the first sub-assembly 1, the second sub-assembly 2 and the third sub-assembly 3.
Note that, if the third sub-member 3 is disposed above the mounting surface and also below the mounting surface, the third sub-member 3 may be used as an axis, including a case where a portion of the third sub-member 3 above the mounting surface is used as an axis, and a case where a portion of the third sub-member 3 below the mounting surface is used as an axis.
Optionally, the first sub-component 1, the second sub-component 2, and the third sub-component 3 form a closed loop, and the closed loop can rotate on a plane parallel to the bearing surface by using the first sub-component 1 or the second sub-component 2 as an axis, wherein the rotatable angle is less than 180 degrees.
For example, please refer to fig. 2h and fig. 2f, which are a side view and a top view of the closed loop formed by the first sub-assembly 1, the second sub-assembly 2 and the third sub-assembly 3.
Optionally, the height of the third sub-assembly 3 relative to the bearing surface is adjustable, the height of the third sub-assembly 3 may be directly adjusted, or the height of the third sub-assembly 3 may be adjusted by adjusting the values of the first included angle and the second included angle. Therefore, the height of the third sub-component 3 relative to the bearing surface can be conveniently adjusted according to the volume of the article, and the tag can be conveniently read by the antenna. Fig. 3 is a schematic view illustrating the height of the third sub-member 3 relative to the bearing surface.
Alternatively, the adjustment means may be mounted on the first sub-assembly 1 and the second sub-assembly 2.
Optionally, an adjustment device is mounted on the third sub-assembly 3, which can be adjusted manually by the user or by a mechanical arrangement.
