The invention provides an automatic arrangement and implantation device for hardware pins of a power supply shell. The automatic arrangement and implantation device comprises a feeding mechanism and adischarging mechanism, wherein the discharging mechanism is arranged in front of the feeding mechanism. The feeding mechanism comprises a support frame, an installation plate, a sliding feeding die,a transverse driving device, a positioning feeding device, a feeding baffle, a first punching device and a second punching device. The discharging mechanism comprises a bottom supporting block, a rearsupporting plate, a linear driving module and a discharging die. The linear driving module is installed on the bottom supporting block and the rear supporting plate. The discharging die is fixed to the linear driving module. Through the cooperation between the first punching device, the second punching device, the positioning feeding device, the transverse driving device, the sliding feeding dieand the feeding baffle of the feeding mechanism and the linear driving module and the discharging die of the discharging mechanism, the automatic positioning feeding, arrangement and implantation of the hardware pins can be realized in the production of the power supply shell, one-time implantation of a plurality of groups of hardware pins can be realized, and therefore the implantation efficiencyof the hardware pins is greatly improved.
