Description

Technical Field

[0001] The utility model relates to a detection device, in particular to an RFID electronic tag entry and exit detection device, belonging to the technical field of RFID electronic tag detection devices. Background Art

[0002] RFID electronic tag technology communicates through radio waves to identify specific targets and read related data without establishing direct mechanical or optical contact with the target. In our daily lives, access control cards are an application form of RFID electronic tags, which mainly rely on RFID technology to achieve wireless identification and data exchange. This technology enables the access control system to identify the cardholder's identity information through radio waves, thereby controlling the opening and closing of the door.

[0003] When access control cards are produced, it is inevitable that defective products with damaged shells will appear. Once the shell is damaged, it cannot effectively protect the internal chip. In order to ensure that the access control cards can be used normally, it is usually necessary to perform non-destructive testing on the produced access control cards. However, the existing technology usually does not have the function of adjusting the detection scanning range. Since there are many specifications of access control cards, the sizes of access control cards of different specifications are also different. If the detection range cannot be adjusted according to the size of the access control cards, it is impossible to effectively collect images of access control cards with larger sizes, which not only reduces the accuracy of the detection results, but also limits the applicability of the device to access control cards of different specifications. At the same time, in the existing technology, there is usually no function of sorting the damaged access control cards detected, and the damaged access control cards can only be sorted manually by the staff, which increases the labor intensity of the staff.
