Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the present application, generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Example 1

Referring to fig. 1-2, a multi-station NFC testing apparatus includes a base 1, where a plurality of testing stations are disposed on the base 1; the test station comprises a tested device fixing unit, an NFC card contact unit and a signal receiving unit 2; the device to be tested fixing unit comprises a fixing seat 3 and a clamping seat fixed on the fixing seat 3, and the device to be tested A is clamped in the clamping seat; the fixed seat 3 is fixed on the fixed seat 3 in a position-adjustable manner; the NFC card contact unit comprises a cylinder 4 and a fixing frame 5 connected to the power output end of the cylinder 4, an NFC card B is fixed on the fixing frame 5, and the cylinder 4 is used for driving the NFC card to approach and depart from a tested device on the card seat; the device under test is electrically connected to the signal receiving unit 2.

In the practical application process, firstly, the tested device, namely the display with the NFC function, is fixed on the card seat, and because the NFC induction parts of different display screens are possibly different, the position of the fixing seat 3 is adjusted after the display screens are fixed on the card seat, so that the NFC card right above the display screens is opposite to the NFC induction part of the display screens, and then the fixing seat 3 is fixed well.
