The embodiment of the present invention provides an electronic tag 30 including a chip and an antenna. The chip is used for detecting and recording on-off information of a detection circuit connected with the electronic tag. The antenna is used for carrying out wireless data exchange with an external electronic tag reader so as to transmit the on-off information of the detection circuit stored in the chip to the electronic tag reader.

When the mechanical parts to be detected rotate relatively, the cutting member 50 cuts the metal detection line 41, which results in the open circuit of the closed circuit formed by the metal detection line 41 and the electronic tag 30. When the electronic tag 30 can detect the occurrence of the open circuit of the closed circuit, it can be known that the mechanical component to be detected rotates to a certain degree to cause the open circuit of the closed circuit, and simultaneously, the open circuit information of the closed circuit is recorded in the chip of the electronic tag.

The device is simple to use, and can quickly and effectively judge the relative rotation of the mechanical part.
In one embodiment, the first detection section 10 includes at least two metal detection lines 41 and 42 therein;
at least one electronic tag 30 is connected with at least two metal detection lines 41 and 42 to form at least one closed circuit;
at least one electronic tag 30 is distributed on the opposite end faces of the first detection part 10 and the second detection part 20 according to a preset angle;
the cutting member 50 is interposed between the at least two metal detecting lines 41 and 42, and cuts at least one of the at least two metal detecting lines 41 and 42 when the two relatively rotatable mechanical members are relatively rotated.
The grooves 11 are arranged in a circular ring shape on the end surface of the first nest portion 12 so that when relative rotation occurs between the mechanical parts to be inspected, the cutting members 50 inserted into the grooves 11 rotate therewith to cut off the metal detection lines 41 and/or the metal detection lines 42 provided across the grooves.
In the following embodiment, the initial position of the cutting member 50 is defined as a 0-degree position.
For example, as shown in fig. 3, the device for detecting relative rotation between mechanical components in the mechanical component inspection system includes a schematic structural diagram of four closed circuits formed by four electronic chips and metal detection lines, wherein four groups of metal detection lines 41 and metal detection lines 42 are arranged on the opposite end faces of the first detection portion 10 and the second detection portion 20, and are provided with 4 electronic tags 30 and 4 independent closed circuits, and the four groups of closed circuits are respectively arranged at 0 degree, 90 degree, 180 degree and 270 degree positions of the circumference of the opposite end faces of the first detection portion 10 and the second detection portion 20.
The initial position of the cutting component 50 is between two metal detection lines of the closed circuit at the 0-degree position, when the mechanical component to be detected relatively rotates, the cutting component 50 cuts off the metal detection line 42 in the clockwise direction, and at this time, the electronic tag 30 can judge that the mechanical component to be detected rotates 0-90 degrees in the clockwise direction. When the cutting component 50 cuts off the metal detection line 41 in the counterclockwise direction, the electronic tag 30 can determine that 0 can determine that the mechanical component to be detected rotates by 0 to 90 degrees in the counterclockwise direction.
When the mechanical part to be detected rotates to a greater extent, the metal detection lines 41 and 42 located at 90 degrees are cut off by the cutting part 50, and then the electronic tag can judge that the mechanical part to be detected rotates by 0-180 degrees in the clockwise direction. If the metal detection lines 41 and 42 at the 270-degree position are cut off by the cutting component 50, the electronic tag can judge that the mechanical component to be detected rotates by 0-180 degrees in the counterclockwise direction.
By analogy, the electronic tag 30 can determine the angle range and the rotation direction of the mechanical part to be detected relative to each other according to the on-off information of the closed circuit caused by the fact that the metal detection lines at different positions are cut off.
In the embodiment, the electronic tags 30 are distributed on the opposite end faces of the first detection part 10 and the second detection part 20 according to the preset angle, and the range and the rotation direction of the rotation angle between the mechanical parts can be conveniently and quickly determined according to the detected condition that the closed circuits at different positions are broken. More accurate information can be provided for maintenance personnel to detect relative rotation between the mechanical components.
More chips and closed circuits may be provided in order to more accurately determine the angular range of rotation occurring between the mechanical parts. However, this will result in increased cost, and therefore the present invention also provides another embodiment that can accurately determine the rotation angle between the mechanical parts using fewer chips, thereby reducing the cost.
In this embodiment, the device for detecting the relative rotation between the mechanical components in the mechanical component inspection system shown in fig. 4 includes a schematic diagram of a 12-closed circuit structure formed by an electronic chip and 13 metal detection lines, and the first detection portion 10 includes an electronic tag 30, a metal detection line 41 and at least two metal detection lines 42;

the cutting member 50 is interposed between the at least two metal detecting wires 41 and 42, and cuts off the at least one metal detecting wire when the two relatively rotatable mechanical members are relatively rotated.
For example, as shown in fig. 4, 1 electronic tag 30, one metal detection line 41 fixed at a position of 0 degree on the opposite end faces of the first detection portion 10 and the second detection portion 20, and 12 metal detection lines 42 are used to form 12 closed circuits, which are evenly distributed on the opposite end faces of the first detection portion 10 and the second detection portion 20. The end faces were divided into 12 portions each at 30 degrees. The cutting member 50 is initially positioned between the metal detecting wires 41 and 42 at the 0 degree position. When the electronic tag detects that the closed circuit at the position of 30 degrees clockwise is opened, the relative rotation angle between the mechanical parts can be determined to be between 0 and 30 degrees in the clockwise direction. When the electronic tag detects that the closed circuit located at the position of 60 degrees clockwise is opened, the angle range of relative rotation between the mechanical components can be determined to be between 0 and 60 degrees in the clockwise direction, and so on, the angle and the direction of rotation between the mechanical components can be determined more accurately by the embodiment.
The utility model discloses do not do the restriction to the electronic tags figure that sets up and the figure that sets up closed circuit. The plurality of electronic tags may respectively form a plurality of closed circuits, or one electronic tag may form a plurality of closed circuits. It is contemplated that the greater the number of closed circuits, the more precise the angle of rotation between the mechanical parts is determined, and at the same time, the complexity of the circuit increases.

The electronic tag is an active antenna RFID tag or a passive antenna RFID tag. And the reading-writing distance between the electronic tag reader and the device for detecting the relative rotation between the mechanical parts is 20-100 cm. The electronic tag is made of ABS plastic (acrylonitrile-butadiene-styrene copolymer).
