[0105] Step two, the digital wheel set automatically threaded: the digital wheel shaft 007 automatically feeds and passes through the number wheel, the red character wheel and the middle hole of the initial wheel through the digital wheel threading device 40, and forms a through hole on the right side of the initial wheel. Digital wheel assembly of good shaft;
[0106] Step three, transfer the number wheel assembly: the number wheel assembly is automatically transferred from the character wheel sorting transition tool 120 set on the character wheel index plate 1 by the number wheel assembly transfer device 50 and placed on the assembly index plate 2 On the corresponding digital wheel assembly mold base 131 in the assembly tool 130;
[0107] Step four, the switch wheel group automatically feeds the shaft: the switch wheel shaft 001 and the switch wheel 002 are automatically fed by the switch wheel group automatic threading and feeding device 60 and the switch wheel shaft 001 passes through the middle hole of the switch wheel 002 to form the switch wheel assembly. Automatic transfer and place on the corresponding switch wheel assembly mold base 132 in the assembly tool 130;
[0108] Step 5, digital wheel set dialing: on the assembly index plate 2 through the digital wheel dialing device 70, each digital wheel of the digital wheel set rotates around the digital axle and reaches the same angle through the limit block, and the digital axle passes the limit Column limit, while pushing the sliding mechanism 133 on the assembly tool 130 to make the digital wheel assembly and the switch wheel assembly correctly mesh;
[0109] Step 6: Counter bracket 003 loading and pressing: The counter bracket 003 is automatically fed and pressed into the engaged digital wheel assembly and switch wheel assembly through the counter bracket automatic feeding and pressing device 80, and the digital wheel shaft and the switch wheel shaft pass through the counter bracket 003 Positioning and fixing of the inner card slot;
[0110] Step 7: Transfer the counter finished product: transfer the counter into the counter tool 140 set inside the assembly index plate 2 through the workpiece transfer device 90;
[0111] Step 8. Visual inspection: visual inspection is performed on the digital consistency displayed by the counter digital wheel in the counter tooling 140 after assembly, through the visual inspection device 100, and the control system 160 automatically judges whether it is qualified or not according to the built-in standard;
[0112] Step 9: Finished product off-line and coding: the counter finished product is automatically off-line through the counter off-line device 110, and the sliding mechanism 133 on the assembly tool 130 is reset at the same time, and then the coding device 150 performs the printing on the outer surface of the qualified counter Coding, the unqualified counter will not print the code on the outer surface of the bracket.
