the deceleration frame detection device 230 detects whether the deceleration frame 1011 and the rotary driving member 1010 are installed in place, and if not, the manual adjustment is carried out; if the installation is in place, the second tooling 3000 flows to the following procedures;

the pin inserting device 240 inserts the first mounting shaft 1013 and the second mounting shaft 1013 onto the reduction bracket 1011, and then the second tool 3000 is shifted to the following steps;

the mounting shaft detecting device 250 detects whether the first mounting shaft 1013 and the second mounting shaft 1013 are properly inserted, and if not, the adjustment is manually performed; if the insertion is in place, the second tool 3000 is shifted to the following procedures;

the first driven gear conveyance/assembly device 260 sucks the first driven gear 1014 from the first driven gear oscillating disc, conveys and assembles the first driven gear 1014 to the first mounting shaft, and then the second tool 3000 is moved to the following steps;

the first driven gear detection device 270 detects whether the first driven gear 1014 is installed in place, and if not, the adjustment is performed manually; if the installation is in place, the second tooling 3000 flows to the following procedures;

the lead screw conveying device 310 grips the lead screw 1016 in the lead screw vibration plate, conveys the lead screw 1016 to the lead screw positioning part 3002 of the second tool 3000 for rotational positioning, and then the second tool 3000 is shifted to the following steps;

the gear greasing device 280 applies grease to the meshing position of the driving gear 1012 and the first driven gear 1014, and then the second tool 3000 flows to the following process;
