[0026] Four positioning fixtures 11 are evenly distributed along the circumferential direction on the upper surface of the turntable 10, and a partition direct vibration feeding track 50 and a lower shell direct vibration feeding track 40 are set on the outer side of the turntable 10. The partition direct vibration feeding track 50 and the lower shell direct vibration feeding track 40 are arranged at a 90-degree interval to provide a partition and a lower shell to the turntable 10 respectively, so that the partition is installed in the lower shell when working.
[0027] A lower shell picking robot 30, a partition picking robot 60, a partition assembly NG unloading robot 70, and a partition combination unloading robot 20 are evenly distributed along the circumferential direction on the stationary disk 80. The lower shell picking robot 30 is used to pick up and place the lower shell that has been transported to the lower shell direct vibration feeding track 40 onto the corresponding positioning tooling 11, the partition picking robot 60 is used to pick up and place the partition that has been transported to the partition direct vibration feeding track 50 and then assemble it into the lower shell, the partition assembly NG unloading robot 70 is used to take out the lower shell that has not been installed with the partition, and the partition combination unloading robot 20 is used to transfer the transferred partition and lower shell assembly to the next station.
[0028] The lower shell picking robot 30, the partition picking robot 60, the partition assembly NG unloading robot 70, and the partition combination unloading robot 20 all include a translation cylinder, a lifting cylinder is installed at the piston rod end of the translation cylinder, a rotary cylinder is installed at the piston rod end of the lifting cylinder, and a gripper cylinder is installed at the rotating part of the rotary cylinder.
[0029] The lower shell picking robot 30, the partition picking robot 60, the partition assembly NG unloading robot 70, and the partition combination unloading robot 20 are respectively installed on the stationary disk 80 through a bracket 13, and the bracket 13 includes a lower bracket 13-1, and a support plate 13-2 is vertically fixed on the top plate of the lower bracket 13-1; the mounting seat of the translation cylinder is fixed on the top plate of the lower bracket 13-1, and the piston rod of the translation cylinder passes through the guide hole of the support plate 13-2 and is fixedly connected to the lifting cylinder.
[0030] The top of the support plate 13-2 is fixed with a mounting frame 13-3, on which a solenoid valve island is installed to control the actions of the lower shell picking robot 30, the partition picking robot 60, the partition assembly NG unloading robot 70, and the partition combination unloading robot 20.
[0031] The mounting frame 13-3 is a frame structure, and a mounting plate is provided on the surface of the frame structure to install the solenoid valve island. The solenoid valve island 90 is a mature product in the prior art, and the solenoid valve island is a control component composed of multiple solenoid valves.
[0032] A hydraulic buffer 13-4 is installed on the support plate 13-2 to achieve buffering for resetting the lifting cylinder.
