When the rotating cylinder rotates, it drives the arc-shaped light barrier piece to rotate and is located at the limit sensor structure or the zero position sensor structure, completing the sensing action. The limit sensor structure 3 and the zero position sensor structure 4 are arranged on the universal harmonic reducer, thereby eliminating the need for additional installation space and improving installation convenience.

[0023] In actual application, the limit sensor structure 3 includes a mounting base 31, a sensor circuit board 32, and a U-shaped sensor head 33.

It is fixed by the mounting base, and in actual application, the angle formed by the center axis of the limit sensor structure, the zero position sensor structure, and the universal harmonic reducer is 90 degrees. The relative position with the sensor light barrier structure is relatively fixed, which is conducive to improving positioning accuracy, anti-interference and stability.

[0024] In actual application, the zero position sensor structure is the same as the limit sensor structure. In order to facilitate connection, the sensor circuit board is provided with four pins or six pins welding points.
