Abstract

The present invention provides a radio frequency identification tag gripper device, the technical scheme including: a first gripper portion; a second gripper portion, which generates a gripping force together with the first gripper portion; a radio frequency identification tag, a circuit portion of which is divided into at least a first section and a second section, an upper surface of the first section and a lower surface of the second section being coated with strong glue, wherein the upper surface of the first section is used to bond with a grip surface of the first gripper portion when gripped tightly, and the lower surface of the second section is used to produce a coupling force with a surface of the gripped object when gripped tightly. Utilizing the technical solution of the present invention, it is possible to further improve the security of monitoring of the radio frequency identification tag.

Claims

1. A radio frequency identification tag gripper device, comprising:

a first gripper portion;

a second gripper portion and said first gripper portion together generate a gripping force;

a radio frequency identification tag a circuit portion of which is divided into at least a first section and a second section;

wherein an upper surface of said first section and a lower surface of said second section are coated with a strong glue;

wherein said upper surface of said first section is used to bond with a grip surface of said first gripper portion when gripped tightly; and

wherein said lower surface of said second section when gripped tightly produces a coupling force with a surface of a gripped object.

2. The device according to claim 1, wherein said lower surface of said second section is directly bonded with said surface of said gripped object to produce said coupling force when gripped tightly.

3. The device according to claim 1, further comprising a slice with one side being coated with weak glue.

4. The device according to claim 1, wherein said grip surface of said first gripper portion comprises a groove which accommodates the radio frequency identification tag and enable said grip surface of said first gripper portion and said gripped object to be closely jointed.

5. The device according to claim 1, wherein the radio frequency identification tag is divided into said first section and said second section by a breakable section.

6. The device according to claim 5, wherein said breakable section crosses said circuit portion of said radio frequency identification tag without damage, so that said circuit portion of said radio frequency identification tag is easily damaged along said breakable section.

7. The device according to claim 5, wherein said breakable section is configured as a straight line, a curve or a closed graph.

8. The device according to claim 1, wherein the viscosity of said strong glue is larger than 1000 cps.

9. The device according to claim 3, wherein the viscosity of said weak glue is 300-600 cps.

10. The device according to claim 3, wherein said lower surface of said second section indirectly bonds with the surface of said gripped object through the slice to produce said coupling force when gripped tightly.

11. A method for monitoring an object with a radio frequency identification tag gripper device, the method comprising the steps of:

monitoring in real time an object gripped by said radio frequency identification tag gripper device to determine whether a signal of said radio frequency identification tag is detected; and

adopting a security measure in response to the signal of said radio frequency identification tag when not detected.

12. The method according to claim 11, wherein the radio frequency identification tag is divided into a first section and a second section by a breakable section.

13. The method according to claim 12, wherein said breakable section crosses a circuit portion of said radio frequency identification tag without damage, so that said circuit portion of said radio frequency identification tag is easily damaged along said breakable section.

14. The method according to claim 12, wherein said breakable section is configured as a straight line, a curve or a closed graph.
