The chip 30 is fixed to the second member 20. The chip 30 includes at least a ground terminal 31 and a detection terminal 32. The at least two sensing lines 40 include a first sensing line 41 and a second sensing line 42, a first end of the first sensing line 41 is electrically connected to the ground terminal 31, and a first end of the second sensing line 42 is electrically connected to the sensing terminal 32. A second end of one first sensing wire 41 is electrically connected to a second end of at least one second sensing wire 42, and the second ends of the first and second sensing wires 41 and 42 are fixed to the first member 10.
The embodiment of the invention provides a device for detecting rotation of a mechanical component, which at least comprises a first detection line and at least a second detection line, wherein one end of the first detection line and one end of the second detection line are fixed on the first component, and the other end of the second detection line are fixed on the second component. And the first detection line is electrically connected with a grounding end on the chip, the second detection line is electrically connected with a detection end on the chip, and the first detection line is also electrically connected with the second detection line, so that when the first detection line and the second detection line are intact, the first detection line, the second detection line and a logic circuit in the chip form a closed circuit. When at least one of the first and second detection lines is opened, a closed circuit is not formed. Thus rotation between the first and second components may be detected depending on whether a closed circuit is formed, the detecting rotation between the first and second components comprising: detecting whether there is rotation between the first member and the second member. The rotation between the first and second components may further comprise: a rotation angle between the first member and the second member is detected.
alternatively, referring to fig. 1 and 2, the distance between the ground terminal 31 of the chip 30 and the first member 10 is equal to the length of the first sensing line 41, and the distance between the sensing terminal 32 of the chip 30 and the first member 10 is equal to the length of the second sensing line 42. That is, the first detecting line 41 having both ends fixed to the first member 10 and the second member 20 is in a straightened state, the second detecting line 42 having both ends fixed to the first member 10 and the second member 20 is also in a straightened state, and if there is rotation between the first member 10 and the second member 20, the first detecting line 41 and the second detecting line 42 are broken, so that a closed circuit is not formed, the chip 30 can detect that there is rotation between the first member 10 and the second member 20, the stranded first detecting line 41 and the stranded second detecting line 42 are intact, the first detecting line, the second detecting line and the logic circuit in the chip form a closed circuit, and the chip 30 can detect that there is no rotation between the first member 10 and the second member 20.
fig. 3 is a schematic diagram of another apparatus for detecting rotation of a mechanical component according to an embodiment of the present invention, fig. 4 is a schematic diagram of a partial structure in fig. 3, and referring to fig. 3 and fig. 4, the apparatus includes N chips 30 (in each embodiment of the present invention, N ═ 2 is used for explanation, and is not limited to the embodiment of the present invention), N first detection lines 41, and N second detection lines 42. The second terminal of one first sensing line 41 is electrically connected to the second terminal of one second sensing line 42. Wherein N is a positive integer greater than 1. In the embodiment of the present invention, each chip 30, one first sensing line 41 and one second sensing line 42 form one sensing group. Within the detection group, the rotation between the first and second members 10 and 20 is detected according to whether the logic circuit in the chip 30, the first and second detection lines 41 and 42 form a closed circuit.
Alternatively, referring to fig. 3 and 4, the first sensing lines 41 and the second sensing lines 42 electrically connected to each other have the same length. In the embodiment of the present invention, each chip 30, one first detection line 41 and one second detection line 42 form one detection group, and the first detection line 41 and the second detection line 42 in the same detection group have the same length. Because the first detection line 41 and/or the second detection line 42 in the same detection group are/is broken, a closed circuit is not formed, if the first detection line 41 and the second detection line 42 in the same detection group are set to have different lengths, the shorter one of the first detection line 41 and the second detection line 42 plays a role of "breaking", and the longer one of the first detection line 41 and the second detection line 42 does not actually play a role of "breaking", that is, the longer one of the first detection line 41 and the second detection line 42 is not necessarily set to be so long, which wastes the length of the detection lines. In the embodiment of the invention, the first detection line 41 and the second detection line 42 which are electrically connected with each other have the same length, so that the length of the detection lines is not wasted, and the first detection line 41 and the second detection line 42 simultaneously play a role in breaking, thereby increasing the detection sensitivity.
Alternatively, referring to fig. 3 and 4, any two second sensing lines 42 of the N second sensing lines 42 have different lengths. In the embodiment of the present invention, any two second detection lines 42 in the N second detection lines 42 have different lengths, so that the N second detection lines 42 can respectively detect different rotation angles between the first component 10 and the second component 20.
Exemplarily, referring to fig. 3 and 4, the 2 chips 30 are a first chip 301 and a second chip 302, respectively. The length of the second sensing lines 42 electrically connected to the first chip 301 is smaller than the length of the second sensing lines 42 electrically connected to the second chip 302. When rotation occurs between the first member 10 and the second member 20, the second sensing wires 42 electrically connected to the first chip 301 are first broken and are detected by the first chip 301. The second sensing wires 42 electrically connected to the second chip 302 are then re-broken and sensed with the second chip 302.
fig. 5 is a partial structural schematic diagram of another apparatus for detecting rotation of a mechanical component according to an embodiment of the present invention, and referring to fig. 5, a chip 30 includes N ground terminals 31 and N detection terminals 32. The device comprises N first detection lines 41 and N second detection lines 42. The second terminal of one first sensing line 41 is electrically connected to the second terminal of one second sensing line 42. Wherein N is a positive integer greater than 1. In the embodiment of the present invention, the N ground terminals 31 and the N detection terminals 32 are integrated in the same chip 30, so that the number of the chips 30 is reduced, and the difficulty of fixing the chip 30 to the second component 20 is reduced.
Alternatively, referring to fig. 5, the first sensing lines 41 and the second sensing lines 42 electrically connected to each other have the same length. In the embodiment of the invention, the first detection line 41 and the second detection line 42 which are electrically connected with each other have the same length, so that the length of the detection lines is not wasted, and the first detection line 41 and the second detection line 42 simultaneously play a role in breaking, thereby increasing the detection sensitivity.
Fig. 6 is a schematic partial structure diagram of another apparatus for detecting rotation of a mechanical component according to an embodiment of the present invention, and referring to fig. 6, a chip 30 includes 1 ground terminal 31 and N detection terminals 32. The device comprises 1 first sensing line 41 and N second sensing lines 42. The second terminal of one first sensing line 41 is electrically connected to the second terminals of all second sensing lines 42. Wherein N is a positive integer greater than 1. In the embodiment of the present invention, the 1 ground terminal 31 and the N detection terminals 32 are integrated in the same chip 30, so that the number of chips 30 is reduced, and the difficulty of fixing the chip 30 to the second component 20 is reduced. Furthermore, in the embodiment of the present invention, only 1 ground terminal 31 is provided, N detection terminals 32 share 1 ground terminal 31, and N second detection lines 42 respectively form a closed circuit with 1 first detection line 41, so that the number of ground terminals 31 is reduced, the number of ports in the chip 30 is reduced, the number of detection lines 40 is also reduced, and the cost and the difficulty in setting are reduced.
Alternatively, referring to fig. 6, the length of the first sensing line 41 is greater than the length of the second sensing line 42. Since the N second detection lines 42 form a closed circuit with 1 first detection line 41, the length of the first detection line 41 is set to be greater than the length of the second detection line 42 in the embodiment of the present invention, so that all the second detection lines 42 can be ensured to break before the first detection line 41, and the first detection line 41 can also form a closed circuit with other second detection lines 42 when one second detection line 42 breaks.
alternatively, referring to fig. 6, any two second sensing lines 42 of the N second sensing lines 42 have different lengths. In the embodiment of the present invention, any two second detection lines 42 in the N second detection lines 42 have different lengths, so that the N second detection lines 42 can respectively detect different rotation angles between the first component 10 and the second component 20.
Optionally, referring to fig. 1-6, the device further comprises an electronic tag 50 and a reader 60. The electronic tag 50 is fixed to the second member 20 and electrically connected to the chip 30. The reader 60 is communicatively coupled to the electronic tag 50. The reader 60 and the electronic tag 50 in the embodiment of the present invention may be in communication connection, for example, in a wireless communication manner, so that information in the chip 30 interacts with the reader 60 through the electronic tag 50, so that a worker can operate, learn and process data.
Alternatively, referring to fig. 1-6, the second member 20 includes a screw 22 and a nut 21, and one end of the screw 22 is fixedly coupled to the nut 21. Chip 30 is secured to the surface of nut 21. The first part 10 comprises a table to which the other end of the screw 22 is secured.
alternatively, referring to fig. 1-6, an electronic tag 50 may also be affixed to the surface of the nut 21. The table may be, for example, a metal table. The detection lines 40 may be copper lines, for example.
