The invention discloses a 4P breaker reflecting plate assembly static contact assembling system; the table top is provided with a multi-station graded circular route; the following units are arrangedin order in an anticlockwise direction and encircles outside the circular route: a static contact feeding mechanism 1 of the first polar groove, a reflecting plate feeding mechanism 1, a press mounting mechanism 1, and a transport mechanism 1; a static contact feeding mechanism 2 of the second polar groove, a reflecting plate feeding mechanism 2, a press mounting mechanism 2, and a transport mechanism 2; a static contact feeding mechanism 3 of the third polar groove, a reflecting plate feeding mechanism 3, a press mounting mechanism 3, and a transport mechanism 3; a static contact feeding mechanism 4 of the fourth polar groove, a reflecting plate feeding mechanism 4, a press mounting mechanism 4, and a transport mechanism 4; the system also comprises a breaker pedestal feeding mechanism, adischarge mechanism, and a vibrating disc controller. The assembling system can replace a manual reflecting plate assembly to assemble the static contact in the breaker pedestal, thus reducing 4-6 people on each production line; the system is simple in operation, can eliminate assembling adverse, and can improve the assembling quality.
