Problems solved by technology

And because the bus ring is generally installed in the center of the photoelectric instrument, the bus ring is easily bumped and deformed during the assembly process, which affects the electrical performance of the bus ring and is not easy to find. Once the product is assembled and enters the working state, it will be reworked and repaired if the problem is found. The difficulty and workload are very large, which affects the assembly quality and production cycle of the product

[0003] Existing detection methods for the electrical performance of bus rings mainly include: automatic detection device for on-off of bus ring (CN102508090A), dynamic contact resistance test device (CN102445601A), automatic detection device for conductive ring CN202255416A, etc., which can automatically detect the static state of bus ring through automatic switching. The on-off state, dynamic contact resistance, etc. under the state, but there is no simulation of the rotation state of the bus ring, and the detection of the bus ring under the rotation condition is not realized, and the electrical properties such as on-off under the rotation state of the bus ring directly affect the work of the product The transmission of various signals such as servo signals in the state, even affects the performance of the entire product

The conductive slip ring dynamic contact resistance measurement tool (CN102520250A) has a rotating device, a static crimping device and a rotary crimping device. The concentric connection between the rotating device and the rotating end of the conductive slip ring is realized through the two crimping devices, and the conductive slip ring The measurement point at the rotating end is converted into a static measurement point by the static crimping device at the same potential, and the detection of the fluctuation of the single-loop resistance of the conductive slip ring can be realized by connecting the measuring instrument, but the detection tool can only be connected at one time The continuous detection of all the loops of the bus ring cannot be realized by the detection of one ring, and this method does not involve the insulation resistance detection between each ring of the bus ring and the ring pair shell. The detection is inconvenient. When the rotating device drives the test confluence ring to rotate, the self-contained line of the confluence ring also rotates continuously, and there are problems such as twisted wires.
