Production line for making short run radio frequency identification tags and labels
View Patent ↗The present invention is a method and apparatus for producing ready to use RFID devices in a convenient and economical manner. The apparatus of the present invention may be collocated with a manufacturer of consumer goods.
1. A continuous radio frequency identification (RFID) production line for producing an RFID device comprising:
a supply of material advancing in a machine direction;
a supply of conductive material, each of the supply of material and conductive material are advanced in the machine direction;
a combination web which advances in the machine direction;
an adhesive coating station for applying a pattern of adhesive to the supply of material;
a laminating station for laminating the supply of conductive material to the pattern of adhesive;
a first cutting station for cutting an antenna pattern in the conductive material, such that the first cutting station has a first die cutting or cold foil process and then laser cutting;
a first printing device for printing human and/ or machine readable indicia on the supply of material;
a chip placement device for placing a chip on the antenna pattern to form the RFID device;
an encoding station for encoding unique information on to the chip that relates to a product associated with the chip;
a discrete printed area; and
a reading and/or scanning station for comparing the encoded information with the human and/or machine readable indicia; where the discrete printed area is removed when information encoded on the chip does not match the human and/or machine readable indicia in the discrete area,
such that the production line can produce an intermediate assembly having at least an RFID device disposed in a label or hang tag.
2. The RFID production line of claim 1 , including a discard station after the reading and/or scanning station for discarding a faulty RFID device.
3. The RFID production line of claim 1 , wherein the chip placement device is provided by one of a strap or direct chip attach device.
4. The RFID production line of claim 1 , wherein the first cutting station is one of a laser cutter or cold foil process.
5. The RFID production line of claim 1 , including a second printing station to provide one of conductive ink to the conductive material or additional human and or machine readable indicia.
6. The RFID production line of claim 1 , wherein the chip placement device is provided with a supply of straps or chips on a web.
7. A continuous radio frequency identification (RFID) production line for producing an RFID device comprising:
a supply of material advancing in a machine direction;
a supply of conductive material each of the supply of material and conductive material are advanced in the machine direction;
an adhesive coating station for applying a pattern of adhesive to the supply of material;
a laminating station for laminating the supply of conductive material to the pattern of adhesive;
a first cutting station for cutting an antenna pattern in the conductive material, such that the first cutting station has a first die cutting or cold foil process and then laser cutting;
a first printing device for printing fixed information on the supply of material and variable information on the supply of material;
a chip placement device for placing a chip on the antenna pattern to form the -RFID device;
an encoding station for encoding information on to the chip;
a discrete printed area; and
a reading and/or scanning station for comparing the encoded information with the fixed and variable information and if information on the chip does not match the fixed and variable information, the device is marked to indicate that the device is defective; and
the discrete printed area is removed;
such that the product line can produce an intermediate assembly having an RFID device in a label or a hang tag.
