The embodiment of the invention provides an intelligent dustproof mechanism which comprises a dustproof plate and an intelligent label identification mechanism connected with the dustproof plate, wherein the intelligent label identification mechanism comprises at least one label identifier, and the label identifier is used for identifying a corresponding label.
In some embodiments, the smart label recognition mechanism further comprises a first guide rail disposed in parallel with the dust guard, and the label recognizer is disposed to be movable along the first guide rail.
In some embodiments, the label includes a bar code, a two-dimensional code, a ring code, a radio frequency label, a color ring label, or the like, and is not limited thereto.
In some embodiments, the smart label identification structure further comprises a first rail carrier coupled to the dust guard, the first rail being disposed on the first rail carrier.
In some embodiments, the intelligent dust guard mechanism further comprises an illumination mechanism coupled to the dust guard. LED lamp etc. can be chooseed for use to lighting mechanism, and it can provide illumination light to under the not good condition of ambient light, do benefit to the label recognizer and discern the label.
In some embodiments, the smart label identification structure further comprises a first drive mechanism for driving the label identifier along the first guide rail. The first driving mechanism may be a motor and a reducer, and is not limited thereto.
In some embodiments, the first rail carrier is fixedly or movably connected to the dust guard. For example, the first rail carrier may be hinged to the dust guard, thereby reducing the occupation of a specific space by the smart label identification structure in the non-operating state.
In some embodiments, the first rail carrier is integrally provided with the dust guard, and/or the first rail is integrally provided with the first rail carrier.
Further, referring to fig. 1 to 4, an intelligent dustproof mechanism 1 in the present embodiment includes a dustproof plate 11 and a frame structure 12 serving as a first guide rail carrier, where the dustproof plate 11 and the frame structure 12 are integrally disposed and form an included angle of approximately 90 degrees therebetween. The frame-shaped structure is integrally formed with a first guide rail 13, the first guide rail 13 extends along a direction parallel to the dust-proof plate 11, the first guide rail is further provided with more than one label identifier 14, and the label identifier 14 can move along the first guide rail and can be in sliding fit or roller fit with the first guide rail.
Further, the intelligent dustproof mechanism may further include a first driving mechanism (not shown) for driving the label identifier to move along the first guide rail. The first drive mechanism may employ a motor or other drive means, and it may be provided integrally with the tag identifier 14. By adopting the design that the label identifier can move along the first guide rail, the label of the article in a larger range can be identified by only one or a few label identifiers, so that the use cost can be reduced.
In some cases, the aforementioned first guide rail may also be omitted. For example, a plurality of tag identifiers may be fixedly mounted on the frame structure, and the plurality of tag identifiers may be sequentially arranged in a direction parallel to the dust-proof plate. However, this approach requires the use of multiple tag identifiers to identify the tags of a relatively large range of items, and thus increases the cost.
Furthermore, the frame-shaped structure can be regarded as a double-layer structure, wherein the upper layer is responsible for fixedly mounting the dustproof wiring, the first guide rail and the like, and the lower layer is provided with one or more label identifiers which can do linear motion with a motor driving device along the first guide rail to identify the labels carried by the articles, so as to count the identity information, the position information and the like of the corresponding articles.
Further, a trolley wire (not shown) may be disposed on the dust-proof plate 11 and/or the frame-shaped structure 12 for power supply and communication during movement of the tag identifier.
Further, an illumination mechanism (not shown in the figure), such as LED lamp beads or LED strips, may be mounted on the dust-proof plate 11 and/or the frame-shaped structure 12.
In this embodiment, the tag may be an RFID tag, a two-dimensional code, a barcode, etc., and accordingly, the tag identifier may employ an RFID antenna, a two-dimensional code identifier, a barcode identifier, etc., without being limited thereto.
Wherein the label may also be a color circle label. The color ring label can comprise one or more ring-shaped identification marks, the ring-shaped identification marks are arranged along the circumferential direction of the outer surface of the article, the identity information of the article is coded by the characteristics of one ring-shaped identification mark and/or the combination of the characteristics of a plurality of ring-shaped identification marks, the characteristics of one ring-shaped identification mark comprise the color and/or the size and/or the shape of the ring-shaped identification mark, and the combination of the characteristics of a plurality of ring-shaped identification marks comprises any one or more of the number of ring-shaped identification marks, the color and/or the size and/or the shape of each ring-shaped identification mark, the arrangement sequence of the plurality of ring-shaped identification marks and the spacing of the plurality of ring-shaped identification marks. The dimension of the annular identification mark, mainly the dimension in the axial direction, can also be considered as the height of the annular identification mark or the width of the area covered by the annular identification mark on the outer surface of the article. One label characteristic of each annular identity mark can indicate at least one piece of information related to the identity information of the corresponding article, the number of the annular identity marks contained in one identity mark group and the arrangement sequence of the annular identity marks can also respectively indicate at least one piece of information related to the identity information of the article, and the distance between any two adjacent annular identity marks can also indicate at least one piece of information related to the identity information of the article. By combining a plurality of annular identification marks, the identification information of the article can be indicated from multiple aspects, so that the article can be more easily identified quickly and accurately. A plurality of annular identifiers may be spaced axially along the respective article.
The color wheel label is characterized in that any one of the annular identification marks is continuously arranged around the circumference of the outer surface of the article, so that when the article is placed in various postures, the annular identification marks can be independently presented and captured by the corresponding color wheel label recognizer, and particularly can be captured by a plurality of color wheel label recognizers from different angles.
Further, the color ring label may further include one or more ring-shaped check marks, the ring-shaped check marks are arranged along the circumference of the outer surface of the article, the check information corresponding to the identity information of the article is encoded by the features of one ring-shaped check mark and/or the combination of the features of a plurality of ring-shaped check marks, the features of one ring-shaped check mark include the color and/or size and/or shape of the ring-shaped check mark, and the combination of the features of a plurality of ring-shaped check marks includes any one or more of the number of ring-shaped check marks, the color and/or size and/or shape of each ring-shaped check mark, the arrangement order of the plurality of ring-shaped check marks, and the spacing between the plurality of ring-shaped check marks. The annular verification marks are more than two, and the annular verification marks can be distributed on two sides of the one or more annular identification marks along the axial direction of the article. Similarly, because any one of the annular check marks is circumferentially and continuously arranged around the outer surface of the article, when the article is placed in various postures, the annular check mark can be independently presented and captured by the corresponding color ring label recognizer, and particularly can be captured by a plurality of color ring label recognizers from different angles.
The color ring label and the annular check mark captured by the color ring label recognizer are analyzed, so that at least the identity information and the check information of the corresponding article can be obtained, and the identity information and the check information of the article are analyzed and compared, so that whether the identity information of the article is recognized accurately or not can be judged.
Wherein, the annular identity mark and the annular verification mark can be fixedly arranged on the outer surface of the article. For example, in some cases, the annular identification mark and the annular verification mark may be annular patterns of different colors formed on the outer surface of the article by printing, spraying or the like, concave or convex annular structures formed on the outer surface of the article by hot pressing, cold pressing, carving or the like, or annular patterns or annular structures integrally formed on the outer surface of the article during the production process of the article. In other cases, the annular identification mark and the annular verification mark can be annular parts made of plastics, rubber, metal, ceramics and the like. The ring member may be removably fitted over the outer surface of the article. Of course, the ring members may be secured to the outer surface of the article by bonding, welding, pressing, screwing, or the like. If the annular identity mark and the annular verification mark which are arranged separately are adopted, the annular identity mark and the annular verification mark are taken down and reused under the condition that the article is damaged and the like. Or when the identity information of the article needs to be adjusted, the color, shape, size, number and combination mode of the annular identity mark and the annular verification mark on the outer surface of the article only need to be correspondingly adjusted.
In some cases, a bar code label may be wrapped around an outer surface of an article with the length of each bar code extending circumferentially around the outer surface of the first article to form the aforementioned annular identification or annular verification or the like. Further, the barcode label used may also be a color barcode label, and in particular, each barcode therein may be set to a different color.
In this embodiment, the main structure of the intelligent dustproof mechanism, i.e. the dustproof plate and the frame structure, may be a commercially available aluminum alloy profile, plastic steel profile, or the like.
