After the PLC receives the arrival position instruction, it issues an instruction for the grabber 2 to start and move horizontally. After the grabber 2 drives to the specified position, the encoder and the travel switch of the grabber 2 send an arrival signal to the PLC. PLC sends a command to grab car 2, grab car 2 stops, arrives at the designated position, PLC sends a command to hydraulic pump station 2-4 again, hydraulic pump station 2-4 receives the command and starts working, drives lifting cylinder 2-9 to move, hanger assembly 2-7 is in place, hanger in place sensor 2-71 senses that lifting cylinder 2-9 is in place, and then feeds back the in-place information to PLC, PLC controls hydraulic pump station 2-4 to maintain pressure, and sends a command to vacuum suction cup system 2-3, vacuum suction cup system 2-3 starts working after receiving the command, vacuum suction cup system 2-3 includes vacuum pump, vacuum pump filter, pipeline, metal vacuum filter, vacuum valve, diverter, manual valve, vacuum joint, vacuum suction cup, vacuum pressure gauge.

[0043] PLC sends a command to hydraulic pump station 2-4 again, hydraulic pump station 2-4 works, lifting cylinder 2-9 retracts, and hanger assembly 2-7 is in place. After the hanger in place sensor 2-71 senses that lifting cylinder 2-9 has retracted, it feeds back the in-place information to PLC, and PLC controls hydraulic pump station 2-4 to maintain pressure, and absorbs the component and mold box from the mold table. PLC sends a command to grab car 2 again, and grab car 2 starts to move horizontally after receiving the command. After the part grab car 2 drives to the specified position, the encoder and the grab car 2 travel switch send an in-place signal to PLC.

The hanger assembly 2-7 is in position, and the hanger in-position sensor 2-71 senses that the lifting cylinder 2-9 is extended into position, and then feeds back the in-position information to the PLC. The PLC controls the hydraulic pump station 2-4 to maintain the pressure, and sends a command to the vacuum suction cup system 2-3. The vacuum suction cup system 2-3 starts working after receiving the command, and relieves the pressure through the vacuum suction cup 2-8. After the pressure is relieved, the small components and the mold box fall on the turning machine 3.

[0044] After receiving the pressure value displayed on the pressure gauge in the vacuum suction cup system 2-3, the PLC sends a command to the hydraulic pump station 2-4 again, the hydraulic pump station 2-4 works, the lifting cylinder 2-9 retracts, and the hanger assembly 2-7 is in place.

[0045] After the small component and the mold box fall on the part turning machine 3, the PLC sends a command to the hydraulic pump station 2-4 to control the oil cylinder 3-1 at the roller mechanism 3-3 to extend, and the roller mechanism 3-3 is hinged with the turning frame 3-2, so that the roller mechanism 3-3 rotates 90 degrees. The PLC receives the signal that the roller mechanism 3-3 is in place, and sends a command to control the oil cylinder 3-1 at the support mechanism 3-4 to extend, and the support mechanism 3-4 is hinged with the turning frame 3-2, so that the support mechanism 3-4 rotates 90 degrees, driving the model and the small component to rotate 90 degrees. LC receives the signal that the support mechanism 3-4 is in place, and issues a command to control the oil cylinder 3-1 at the roller mechanism 3-3 to retract. After the prefabricated small components and the model are flipped, the PLC receives the signal that the roller mechanism 3-3 is in place, and issues a command to control the oil cylinder 3-1 at the support mechanism 3-4 to retract. After receiving the signal that the roller mechanism 3-3 is in place, the PLC issues a command to the vibrator 3-5, and the vibrator 3-5 starts to vibrate at a high frequency, so that there is a gap between the mold box and the small components. After the vibrator 3-5 vibrates, the PLC receives the information. It also issues a command to the roller mechanism 3-3. After receiving the command, the roller mechanism 3-3 starts to work, driving the small components and the mold box to the roller conveyor line of the production line. The demolded model can be taken out manually or by a robot. The small component flipping, demolding and transportation integrated machine repeats the operation of the next cycle again.
