Description

The invention relates to the field of radio engineering and can be used in the manufacture of plastic sealing devices (indicator seals) with their radio frequency identification.

It is widely known to integrate RFID tags into plastic sealing devices. As a rule, to install radio-frequency tags in a sealing device, the body of the sealing device must have a special cavity for placing a radio-frequency tag into it, made in the form of a plate (RF patent No. 16515, 10.01.01). This cavity is subsequently closed with a separate cover or other structural elements, which, in turn, can be additionally glued or welded to the sealing device to improve protection against dust and moisture.

The disadvantages of such solutions is that the integration of a radio frequency tag into the body of the sealing device is possible only if there is a cavity (understatement) for placing a radio frequency tag in it, which complicates the design of the sealing device and the process of installing a radio frequency tag, especially if it is necessary to install radio frequency tags on a series of sealing devices. Thus, such marks are not universal, they cannot be installed on any type of sealing device, but only on those that contain the said cavity for installation. In addition, the process of installing a radio frequency tag becomes more complicated, since the radio frequency tag is installed individually in each body of the sealing device, which takes some time. In this case, after installing the radio-frequency tag in the sealing device, it is required to close the radio-frequency tag with a lid or other structural elements to prevent moisture from entering the cavity or howling. Closing the radio frequency tag also complicates the design of the sealing device, increases the duration of the tag integration process and increases the cost of the product. Thus, the need to integrate RFID tags into a series of sealing devices from a plurality of devices requires a lot of labor and a long installation time.

Also, the disadvantages of such solutions are pre-embedded structural elements in the sealing device, which are not necessary when using the same sealing device without RFID, which additionally leads to an increase in cost when using the same sealing devices without RFID.

Radio frequency tags are also known that have an adhesive tape on one side for gluing the tag onto the surface of the sealing device. In this case, the label can be attached to the sealing device of any design. However, the use of this type of tags for fixation on the sealing device leads to the loss of the reading range or the complete loss of RFID, which, as a result, reduces the reliability of the RFID of the sealing device. This is because the tag is not protected from dust and water, which leads to its contamination or flooding with water. These tags are limited in use and cannot be used with a sealer used outdoors or in dirty or wet conditions. Moreover, this option of using a radiofrequency tag on a sealing device does not protect them from being removed or re-glued to another device, while leaving no visible traces.

Often, sealing devices are produced in blocks in the form of several identical sealing devices interconnected by a temporary connection. During operation, sealing devices (connected, for example, by jumpers) are disconnected and used separately (individually).

The technical problem to be solved by the claimed invention is to develop a device for rapid RFID marking of plastic sealing devices interconnected by a temporary connection into a block, providing reliable integration into plastic sealing devices with the elimination of the need for special structural elements in the form of cavities for radio frequency tags. and separate covers, reducing the cost of the integration process and the possibility of operating a sealing device with an integrated tag outdoors without losing the radio-frequency properties of the tag, as well as maintaining protection against re-sticking the radio tag onto other devices.

The technical result of the invention is to increase the reliability of the radio frequency identification of the sealing device, to simplify and accelerate the process of integrating an RFID ( radio frequency) tag onto a series of sealing devices combined into a block, to increase the service life of the RFID tag integrated into the sealing device.

The specified technical result is achieved in a device for RFID marking of a block of at least two identical plastic sealing devices connected to each other and separated by a tear line with jumpers at the border of two adjacent sides, which is a plate (or further Protective plate) formed by at least two identical segments interconnected and having outer and inner sides, while the width of each segment in the plate corresponds to the width of the marking plane of each of the sealing devices; on the border between the segments, a separation line with notches is made; each segment on the inside contains a fixed RFID tag that does not protrude beyond the edges of the segment and notches;

the plate is made of a material similar or similar in composition to the material of the sealing device, and each segment is made with the possibility of welding its inner side to the marking surface of the body of the corresponding sealing device along the perimeter of the segment,

moreover, the tear line between the plate segments is made in response to the tear line between two sealing devices corresponding to the plate segments.

RFID tags are attached to the inside of each segment on one side of the plate.

RFID tags can be attached to the inside of each plate segment in the center of the side.

The possibility of welding each segment with its inner side to the marking surface of the body of the corresponding sealing device along the perimeter from the outside provides reliable protection of the radio frequency tag from dust, moisture, etc., which allows the use of the sealing device with the tag outdoors and under any weather conditions with maintaining the reading range, which, as a result, increases the reliability of the radio frequency identification of the sealing device and the service life of the RFID tag integrated into the sealing device. Moreover, each RFID tag is protected from attempts to re-glue it, since when you try to detach the welded protective segments, they are destroyed, leaving visible traces of impact.

The plate may contain more than two segments connected by the sides in a chain.

The plate can be made of a material similar or similar in composition to the material from which the block of sealing devices is made, for example, polypropylene, polyethylene, polyamide, and others. The implementation of the protective plate of these materials allows for a strong welding of the plate segments with RFID tags to the marking surface of the sealing devices, which leads to an increase in the reliability of the radio frequency identification of the sealing device.

Welding of the plate segments to the marking plane of the body of the sealing device can be carried out using ultrasound.

Self-adhesive RFID (radio frequency) tags can be used to fix the plate segments. Self-adhesive RFID tags due to the single plane of the plate can be applied to its segments automatically on a conveyor using an applicator.

For forensic protection against the removal of a radio frequency tag protected by an individual segment, it is allowed to use notches on each of the protective segments, which, when trying to tear off an individual protective segment from a plastic sealing device, tear, damage and leave a lot of visible marks that fix an attempt to remove the protective segment.

The implementation of the device for RFID marking of plastic sealing devices in the form of a plate of several protective segments with RFID tags allows you to put this plate on a block of the appropriate number of sealing devices (PU) and weld several segments at a time. This leads to a significant acceleration and simplification of the process of integrating RFID tags into a series of PUs compared to the integration process, which includes the individual location and fixing of each individual RFID tag on several PUs. In addition, the implementation of the plate with tear lines between the plate segments, which correspond to the tear lines between the sealing devices in the block, allows, after welding of the plate segments, to quickly and easily disconnect the required number of sealing devices along the tear line for their use. It also simplifies and speeds up the manufacturing process for RFID PUs.

At the same time, the presence of tear lines between the plate segments and the possibility of their joining with the response tear lines between the sealing devices in the block allows you to place RFID tags strictly on the marking surfaces (correct location) of the PU series in order to avoid their damage when welding the plate segments in case of displacement of the marks relative to the marking surfaces. That is, since the plate is made in such a way that the RFID tags do not protrude beyond the edges of the segments and notches, this allows you to place RFID tags on the marking surface when joining lines, eliminating the risk of them falling into the welding area and damaging them, which will lead to loss of RFID PU.

Thus, the implementation of the plate with tear lines between the plate segments allows you to quickly and correctly position RFID tags on the marking surfaces of the PU, since the tear lines are a guide, visually well distinguishable on the plate due to the presence of notches. Thus, it is not difficult to correctly place the entire plate on the PU block by simply matching the tear lines between the plate segments with the tear lines between the sealing devices in the block.

Protective plates can be stacked and loaded into a cassette for their sequential extraction by a manipulator and placement on blocks of plastic sealing devices. A protective plate with applied radio tags is placed on a block of plastic sealing devices (seals) on the marking surfaces of the seals. At the same time, the plate is placed on the block of sealing devices in such a way that RFID tags on each of the sections are adjacent to the marking surface of the corresponding sealing devices. As a result, after welding of the plate sections, each RFID tag is located between the marking surface of the body of the sealing device and the outer surface of the section. Thus, the plate (in particular, each of the sections), when used in this way, performs a protective function for the RFID tag after welding of the plate.

As a result of the use of protective plates, a high-tech high-speed process is obtained for obtaining plastic sealing devices with radio frequency identifiers (tags) without any additional structural elements in sealing devices, ensuring complete tightness and visual protection against removal and replacement of the radio frequency identifier (tag).

The claimed invention is illustrated by figures 1-4.

The specified technical result is achieved in the use of special protective plates 1, made of a material similar or close to the chemical composition of the material to the material of the sealing devices 3 themselves, connected in block 2.

The protective plate 1 differs in that its shape is intended immediately for the block of sealing devices 2, interconnected by jumpers 5.

The protective plate 1 has transverse tear lines with notches 7, the number of which is a multiple of the number of transverse tear lines with jumpers 5 in the block 2 of sealing devices 3, forming individual protective segments 6 for each individual sealing device 3.

That is, the number of protective segments 6 in plate 1 corresponds to the number of sealing devices 3 in block 2.

On the inner side of the segments 6 of the protective plate 1, in the center of the segments, self-adhesive radio-frequency tags 8 are placed, not going beyond the tear lines with notches 7, so that the central axis 10 of the self-adhesive radio-frequency tag 8 is closer to the central axis 9 of each individual individual protective segment 6 tending to their alignment. Preferably automated gluing of radio frequency tags 8 on the segments 6 of the protective plate 1 due to the conveyor and automatic applicator.

The protective plate 1 with radio frequency labels 8 applied to the protective segments 6 is placed on the block of plastic seals 2 in the place chosen for this. The tear lines with transverse notches 7 must match the tear lines with jumpers 5 of the sealing devices 3 in block 2. The presence of tear lines makes it easier to correctly place the segments on the sealing devices and center the RFID tags on the segments. Preferably automated stacking of protective plates 1 taken from previously formed stacks.

After that, ultrasonic welding takes place along the perimeter of each of the protective segments 6, separated by tear lines with transverse notches 7. As a result of welding, a welding seam 11 is formed around the radio frequency tag 8, creating a tightness that protects the radio tags from dust and moisture.

Each of the plastic sealing devices 3 can be easily separated from the block 2 together with the welded individual protective segment 6 along the tear lines with jumpers 5 and along the tear lines with transverse notches 7.

For forensic protection against removal of radio frequency tag 8 protected by an individual segment 6, it is allowed to use notches 14 on each of the protective segments 6, which, when trying to tear off an individual protective segment 6 from a plastic sealing device 3, tear, damage and leave a lot of visible marks that fix an attempt to remove the protective segment 6.

As a result of the use of protective plates, a high-tech high-speed process is obtained for obtaining plastic sealing devices with radio frequency identifiers (tags) without any additional structural elements in sealing devices, ensuring complete tightness and visual protection against removal and replacement of the radio frequency identifier (tag).

Thus, as a result of the implementation of the developed device for RFID marking of plastic sealing devices, its performance is improved by increasing the reliability of the radio frequency identification of the sealing device, simplifying and accelerating the integration process. RFID tags for a series of sealing devices combined into a block, increasing the service life of an RFID tag integrated into a sealing device, increasing forensic protection against removing or re-gluing an RFID tag, with the possibility of simply installing the said device on sealing devices of any design. A plate with RFID tags is securely fixed on the planes of sealing devices and excludes the possibility of removing or re-sticking RFID tags without leaving visible marks.
