Description

Technical Field

[0001] This utility model relates to a high-efficiency separation device for miniature RFID tags, belonging to the field of radio frequency tag manufacturing technology. Background Technology

[0002] With the increasing application of RFID technology and products across various industries, many application scenarios requiring small-sized tags have emerged. Small-sized RFID tags are defined as products with smaller dimensions, such as a diameter of 6mm or less. The tag processing method involves first laminating the entire antenna, double-sided adhesive, and backing paper together, then die-cutting it to a predetermined size, and finally removing the non-tag parts—a process known as waste removal. Because small-sized tags have a small area, the adhesion between the tag and the backing paper via double-sided adhesive is also weak. During waste removal, insufficient die-cutting or the presence of adhesive at the cut edges can cause some tags to be removed simultaneously, resulting in tag waste and increased difficulty in subsequent processing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-efficiency separation device for micro RFID tags, which is designed with a roller structure to move the entire sheet of tags after synchronous die cutting, so as to efficiently separate the tags from the waste.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution: This utility model designs a high-efficiency separation device for micro RFID tags, used to separate tags from waste material after die-cutting of the entire label sheet. It includes a main roller, a base, and various separation components. The bottom of each separation component is respectively arranged around the curved surface of the main roller, forming a row of separation components. Based on the assembly line movement of the die-cut labels, the main roller is located on one side of the target position corresponding to the tag on the assembly line movement path after die-cutting, and the base is located on the side of the die-cut label sheet after die-cutting. The label assembly line moves along a path corresponding to the main roller on one side of the backing paper. The rotation of the main roller is synchronized with the assembly line movement of the die-cut labels. Supported by a base, the front ends of each column of separators on the main roller press against the base, separating each label from its original surface layer and attaching it to the backing paper. After the die-cut labels have moved past the position set by the main roller, the original surface layer of the labels on the die-cut labels separates from the backing paper, achieving separation of the labels from waste materials.

[0005] As a preferred technical solution of this utility model: at least one column of installation areas is set on the circumference of the main roller surface, each column of installation areas is arranged in a straight line, the straight line of each column of installation areas is parallel to the central axis of the main roller, the distance between each pair of adjacent columns of installation areas is equal, based on the maximum number of labels a in a single row of label areas on the whole label, a installation points are arranged on each column of installation areas, and the distance between adjacent installation points in each column of installation areas is equal to the distance between adjacent labels in a single row of label areas on the whole label;

[0006] The number of separators is equal to the total number of mounting points on the main roller, and each separator corresponds to a mounting point on the main roller. The structures of each separator are the same, each separator is in a straight line, and the bottom of each separator is located at the corresponding mounting point on the main roller. The straight line of each separator passes perpendicularly through the central axis of the main roller.

[0007] After die-cutting, the entire label sheet moves along the assembly line perpendicular to each row of label areas. The central axis of the main roller is perpendicular to the assembly line direction of the die-cut label sheet. The main roller rotates in the same direction as the die-cut label sheet moving along its label-facing side. The surface of the base facing the backing paper is flat.

[0008] Based on the synchronous rotation of the main roller and the production line movement of the die-cut labels, with the base as support, the front ends of the separation parts set on each row of mounting areas on the main roller press each label in each row of label areas on the die-cut labels in turn towards the base, separating each label from its surface layer and pasting it onto the backing paper.

[0009] As a preferred technical solution of this utility model: each of the separating components includes an extension shaft and a fixed structure. Both the extension shaft and the fixed structure are straight, and the extension shaft is a length-extendable structure. One end of the extension shaft forms the bottom of the separating component, the bottom end of the fixed structure is connected to the other end of the extension shaft, and the straight line of the fixed structure is collinear with the straight line of the extension shaft. The front end of the fixed structure forms the front end of the separating component.

[0010] As a preferred technical solution of this utility model: the edge hub range of the front end of each separator is smaller than the edge hub range of a single label on the entire label.

[0011] As a preferred technical solution of this utility model: a concave area is provided on the front end surface of each separator, so as to avoid the radio frequency chip in the label when the front end of the separator presses the label on the whole label.

[0012] As a preferred technical solution of this utility model: based on the distance D between adjacent label rows on the entire label sheet, the end face radius R of the main roller, the number N of columns of the separators on the main roller, and the length H of the separators, the following conditions are met:

[0013]

[0014] As a preferred technical solution of this utility model, it also includes a first power device and a second power device located downstream of the main roller in the direction of movement of the die-cut label production line. Based on the separation of the label surface and the backing paper after the die-cut label moves past the position set by the main roller, the first power device and the second power device respectively connect to the label surface and the backing paper, and work synchronously to collect the label surface and the backing paper respectively.

[0015] As a preferred technical solution of this utility model: the first power device is a waste recycling roller, and the second power device is a label recycling roller. The waste recycling roller rotates to wind and collect the surface layer where the label is located, and the label recycling roller rotates to wind and collect the backing paper.

[0016] The efficient separation device for miniature RFID tags described in this utility model, compared with the prior art, has the following technical advantages:

[0017] (1) The present invention designs a high-efficiency separation device for micro RFID tags. The design uses a main roller with a series of separation parts arranged around its curved surface. In conjunction with the production line movement of the die-cut full sheet of tags, the front ends of the separation parts on the main roller press each tag in each row of the die-cut full sheet of tags toward the base in sequence, separating each tag from its surface layer and pasting it onto the backing paper. This efficiently separates the tags from the waste. Furthermore, a first power device and a second power device are designed downstream of the main roller. The first power device and the second power device work synchronously to dock with and collect the surface layer and the backing paper where the tags are located, respectively, so as to collect the tags and waste separately. This can effectively solve the problem of reduced yield caused by the tags being carried away by waste in conventional production and improve production efficiency. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] To address the shortcomings of existing technologies, this utility model specifically designs a high-efficiency separation device for micro RFID tags, used to separate tags from waste materials after die-cutting of the entire sheet of tags 6. Figure 1 As shown, the design device includes a main roller 1, a base 2, and various separating components 3. The bottom of each separating component 3 is respectively set on one circumference of the curved surface of the main roller 1, forming a row of separating components 3. Based on the production line movement of the die-cut full-sheet labels 6, the main roller 1 is located on the side of the target position corresponding to the label on the production line movement path of the die-cut full-sheet labels 6, and the base 2 is located on the side of the backing paper corresponding to the position of the main roller 1 on the production line movement path of the die-cut full-sheet labels 6. Based on the synchronous operation of the rotation of the main roller 1 and the production line movement of the die-cut full-sheet labels 6, with the base 2 as support, the front ends of each row of separating components 3 on the main roller 1 press each row of labels on the die-cut full-sheet labels 6 towards the base 2 in sequence, separating each label from its surface layer and pasting it onto the backing paper. After the die-cut full-sheet labels 6 move past the position set by the main roller 1, the original surface layer of the label on the die-cut full-sheet labels 6 separates from the backing paper, realizing the separation of the label from the waste material.

[0024] Based on the above design direction, in practical applications, at least one row of installation areas is set around the curved surface of the main roller 1. Each row of installation areas is arranged in a straight line, and the straight line of each row of installation areas is parallel to the central axis of the main roller 1. The distance between each pair of adjacent rows of installation areas is equal. Based on the maximum number of labels 'a' in a single row of label areas on the entire label sheet, 'a' installation points are set on each row of installation areas, and the distance between adjacent installation points in each row of installation areas is equal to the distance between adjacent labels in a single row of label areas on the entire label sheet.

[0025] Based on the above-designed mounting points on the main roller 1, the number of separation parts 3 is equal to the total number of mounting points on the main roller 1, and each separation part 3 corresponds one-to-one with each mounting point on the main roller 1. The structures of each separation part 3 are the same, each separation part 3 is in a straight line, and the bottom of each separation part 3 is set at the corresponding mounting point on the main roller 1. The straight line of each separation part 3 passes perpendicularly through the central axis of the main roller 1, thus completing the installation of each separation part 3 on the main roller 1.

[0026] Based on the flow of the die-cut label 6 along the direction perpendicular to each row of label areas, the main roller 1 is located on the side of the label corresponding to the target position on the flow path of the die-cut label 6. The central axis of the main roller 1 is perpendicular to the flow direction of the die-cut label 6. The main roller 1 rotates in the same direction as the flow direction of the die-cut label 6 with the side facing the label. The base 2 is located on the side of the base paper corresponding to the position of the main roller 1 on the flow path of the die-cut label 6. The surface of the base 2 facing the base paper is flat.

[0027] In the application, the rotation of the main roller 1 is synchronized with the production line movement of the die-cut full-plate label 6. With the base 2 as support, the front ends of the separation parts 3 set on each row of mounting areas on the main roller 1 press each label in each row of label areas on the die-cut full-plate label 6 in turn towards the base 2, separating each label from its surface layer and pasting it onto the backing paper, thus realizing the separation of the label from the waste material.

[0028] Regarding the separation of labels and waste materials under the above-mentioned design structure, in practical applications, such as... Figure 1 As shown, a first power unit 4 and a second power unit 5 are further designed and added downstream of the main roller 1 in the direction of movement of the die-cut label 6 on the production line. Based on the separation of the label surface and the backing paper after the die-cut label 6 moves past the position set by the main roller 1, the first power unit 4 and the second power unit 5 respectively connect to the label surface and the backing paper. The first power unit 4 and the second power unit 5 work synchronously to collect the label surface and the backing paper respectively.

[0029] And in practical applications, such as Figure 1 As shown, the first power unit 4 is a waste recycling roller, and the second power unit 5 is a label recycling roller. The waste recycling roller rotates to wind and collect the label surface layer, and the label recycling roller rotates to wind and collect the backing paper. In application, the waste recycling roller and the label recycling roller are spatially misaligned and rotate synchronously with each other. On the one hand, the waste recycling roller and the label recycling roller wind and collect the separated label surface layer and the backing paper. On the other hand, they achieve synchronous traction of the label surface layer and the backing paper, which provides power for the assembly line movement of the die-cut label sheet 6.

[0030] The above describes the efficient separation device for micro RFID tags designed in this utility model, which achieves the separation and recycling of tags and waste. In further practical applications, the design of each separating component 3 is further refined. Each separating component 3 includes an extension shaft 3-1 and a fixing structure 3-2. Both the extension shaft 3-1 and the fixing structure 3-2 are straight lines. The extension shaft 3-1 is a telescopic structure, with one end forming the bottom of the separating component 3. The bottom end of the fixing structure 3-2 is connected to the other end of the extension shaft 3-1, and the straight line of the fixing structure 3-2 is parallel to the line of the extension shaft 3-1. When the straight lines are collinear, the front end of the fixed structural component 3-2 constitutes the front end of the separating component 3. In this way, the length of each separating component 3 can be adjusted in a personalized manner in practical applications. For example, in the label areas of each row of labels on the die-cut label sheet 6, some positions have labels and some positions do not. The length of the separating component 3 at the corresponding position on the main roller 1 can be shortened. That is, during operation, the separating component 3 at this position does not participate in pressing the corresponding unlabeled position on the die-cut label sheet 6. Other positions with labels on the die-cut label sheet 6 still receive the pressing of each separating component 3, pressing the label onto the backing paper and realizing the separation of the label from the waste material.

[0031] Regarding the further design of the separator 3, for example, the edge hub range of the front end of each separator 3 is smaller than the edge hub range of a single label on the entire label sheet, thus ensuring that the separator 3 will not press into non-label areas. Furthermore, a concave area is provided on the front end surface of each separator 3 to avoid the radio frequency chip in the label when the front end of the separator 3 presses against the label on the entire label sheet.

[0032] In practical applications, to ensure that each separator 3 can accurately press down on the label, such as... Figure 2 and Figure 3 As shown, based on the distance D between adjacent label rows on the entire label sheet, the end face radius R of the main roller 1, the number N of each separator 3 distributed on the main roller 1, and the length H of the separator 3, a design is made that satisfies... If the separating component 3 is designed with the extension shaft 3-1 and the fixed structural component 3-2, then based on the length H1 of the extension shaft 3-1 and the length H2 of the fixed structural component 3-2, the following conditions are met:

[0033] The aforementioned structure designs a high-efficiency separation device for micro RFID tags. It features a main roller 1 with rows of separators 3 arranged around its curved surface. This works in conjunction with the production line movement of the die-cut label sheet 6. The front ends of the separators 3 on the main roller 1 press sequentially towards the base 2, separating each tag from its corresponding label layer and attaching it to the backing paper. This efficiently separates the tags from the waste material. Furthermore, a first power unit 4 and a second power unit 5 are designed downstream of the main roller 1. These power units work synchronously, docking with and collecting the label's label layer and the backing paper respectively, achieving separate collection of tags and waste. This effectively solves the problem of reduced yield caused by tags being carried away by waste in conventional production, thus improving production efficiency.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
