The top cover hopper mechanism is provided with a flexible vibrating disc 61 for placing the top cover nut 60. The flexible vibrating disc 61 can vibrate to disperse the material. The material handling robot can grab the valve core 30 on the tooling tray 31 and place it into the corresponding waterway opening when the waterway 20 is transported to the first station; when the waterway 20 is transported to the third station, it grabs the upper cover nut on the flexible vibrating plate 61 and places it above the corresponding valve core 30 for pre-locking. The clamping mechanism 5 is located at the second station and can clamp the valve core 30 placed in the corresponding waterway opening. The upper cover tightening mechanism 7 is located at the fourth station and can tighten the pre-locked upper cover nut 60.

[0043] Furthermore, it also includes a cabinet 11, which is connected to the top surface of the machine platform 1. Each mechanism is located inside the cabinet 11, and the material picking and placing visual positioning mechanism is connected to the top surface inside the cabinet 11.

[0044] It also includes a control system, which is used to control the operation of each mechanism. The control system includes a contact-type industrial computer and a start button. The start button and the contact-type industrial computer are located on the side of the cabinet 11. The operator can start the equipment by using the start button and input the operation command by using the industrial computer.

[0048] S3: Tooling circulation line 22 delivers water channel 20 to each installation station in sequence. During the transmission, the loading vision positioning mechanism 81 takes pictures of water channel 20 to determine whether water channel 20 is correct and without abnormalities.

[0049] S4: When the waterway 20 is delivered to the first work station, the positioning cylinder 24 extends to position and fix it. At the same time, the valve core picking and placing robot 41 grabs the valve core 30 on the tooling tray 31. The valve core picking and placing visual positioning mechanism 82 takes a picture of the valve core and judges whether the valve core is grabbed incorrectly. If there is no error, the valve core picking and placing robot 41 places the valve core 30 into the corresponding waterway opening.

[0050] S5: Positioning cylinder 24 retracts, tooling circulation line 22 continues to transport waterway 20 to the second station, positioning cylinder 24 extends to position, and pressing cylinder 52 extends to press valve core 30 into the corresponding waterway opening.
