The positioning surface (624) contacts the side of the baffle plate (622), and the valve core is clamped through the baffle plate (622) and the receiving groove (625), so as to realize secondary positioning of the valve core and ensure assembly accuracy; the material taking cylinder (634) drives the suction cup (635) to move vertically downward, and picks up the valve core through the suction cup (635), and then the material taking cylinder (634) drives the valve core to move vertically through the suction cup (635), so that the valve core is separated from the receiving groove (625); the servo motor (627) drives the rotating frame (623) to reset; the third cylinder linear module (632) is driven by the third cylinder linear module (632) to move vertically downward, and the valve core is picked up through the suction cup (635), and then the material taking cylinder (634) drives the valve core to move vertically through the suction cup (635), so that the valve core is separated from the receiving groove (625); The valve core is driven to move to the upper side of the lower valve seat through the support plate (633), the material taking cylinder (634) and the suction cup (635); the material taking cylinder (634) drives the valve core to move vertically downward through the suction cup (635), and the valve core presses the column rod (3132) downward, and the spring (3131) is compressed; until the valve core moves into the lower valve seat, the groove on the valve core is engaged with the block on the valve stem; the material taking cylinder (634) and the suction cup (635) are reset, and the third cylinder linear module (632) drives the support plate (633) to reset; the rotating table (2) drives the carrier (3) to rotate; Step 4: At the fourth station, the pressing assembly (64) presses down the valve core again. After the pressing assembly (64) is reset, the rotating platform (2) drives the carrier (3) to continue rotating. Step 5: At the fifth station, the assembly component (71) installs the upper valve seat onto the lower valve seat, and during this process, the glue coating component (72) is used to coat the connection between the upper valve seat and the lower valve seat with glue; then the assembly component (71) and the glue coating component (72) are reset; and the rotating table (2) drives the carrier (3) to continue rotating; Step 6: At the sixth station, the unloading assembly (8) removes the assembled valve.
