[0056] The operation process of the present invention: the steps are as follows:

[0057] Step 1: Loading the mobile phone shell: placing the mobile phone shell on the conveyor belt 803 of the mobile phone shell conveying unit, starting the conveying motor 802 to convey the mobile phone shell to a preset position and then fix it;

[0058] Step 2: Piston loading: Put the piston 225 into the vibration plate 211. The vibration plate 211 vibrates to make the piston flow out of the flow channel 212 in the set direction. At this time, the material hole is connected to the flow channel 212, so the piston finally flows into the material hole 224. Then the rotating mechanism drives the fixed block 223 to rotate 90 degrees to make the piston in a vertical state for easy clamping of the clamping claws.

[0059] Step 3: Piston fixing: The piston feeding module 230 clamps the piston and sends it to the piston fixing unit 300, and the piston fixing unit fixes the piston, specifically: the first horizontal driving mechanism 231 and the first up-and-down driving mechanism 232 adjust the position of the first clamping cylinder 233, so that the first clamping cylinder 233 runs to the piston, the first clamping cylinder 233 drives the first clamping jaw 234 to close and clamp the piston, and then the first clamping cylinder 233 runs to the empty piston fixture 303 through the first horizontal driving mechanism 231 and the first up-and-down driving mechanism 232, and places the piston at the discharge port 304 of the piston fixture 303, and then closes the piston clamps 305 on both sides to clamp and fix the piston, that is, the piston is placed vertically in the piston fixture to facilitate the subsequent placement of the sealing ring;

[0060] Step 4: Sealing ring loading: At the same time, the sealing ring is loaded through the sealing ring loading module, specifically: first pull out the drawer 412 (such as Fig.14 ), the material bin 413 is pulled out of the fixing frame 411 together, and then the sealing ring is placed in the material bin, the drawer is closed to make the material bin return to the fixing frame 411 again, and then air is blown into the material bin through the blowing module 415 to make the sealing ring flow through the material channel to the material taking port 414;

[0061] Step 5: Oiling the sealing ring: The sealing ring feeding module 420 inserts the sealing ring in the feeding port and sends it to the sealing ring oiling unit for oiling. Specifically, the feeding needle 424 moves to the top of the sealing ring of the feeding port under the drive of the second and third horizontal driving mechanisms, and moves downward under the drive of the second up and down driving mechanism to be inserted into the hole in the middle of the sealing ring to take the sealing ring out of the feeding port. The scraper 425 is located above the sealing ring. Then the sealing ring feeding module 420 sends the sealing ring to the sealing ring oiling unit 500 and places the sealing ring between the oiling jaws. Then the oiling jaws 502 are closed so that the sealing ring is just placed in the oiling hole 503. The oil inlet module 504 injects oil into the oiling hole to complete the oiling operation of the sealing ring.

[0062] Step 6: Assemble the sealing ring in the piston: After the sealing ring is oiled, the oiling jaws 502 are opened, and finally the sealing ring feeding module 420 delivers the sealing ring to the piston on the piston fixture 303, and the scraper 425 scrapes the sealing ring into the slot of the piston 225 under the action of the scraper driving cylinder;

[0063] Step 7: Piston flipping: After the sealing ring is placed in the groove of the piston on the piston fixture 303, the turntable 301 drives the piston fixture to move to the bottom of the flip unit 600, and the upper and lower cylinders 604 drive the second clamping cylinder 602 to move downward to the piston, and the second clamping cylinder drives the second clamping cylinder 603 to close and clamp the piston, and the upper and lower cylinders 604 drive the flipping cylinder 601 to move upward to the preset position, and the flipping cylinder 601 drives the piston to rotate 180° to wait for the robot to pick up the material;

[0064] Step 8: Assembling the piston to the mobile phone shell: the transport cylinder 703 drives the third clamping cylinder 704 to move downward to the piston, the third clamping cylinder drives the third clamping jaw to close and clamp the piston, the ejection cylinder 702 extends and supports the root of the piston, and then the manipulator delivers the piston to the mobile phone shell of the mobile phone shell conveying unit and translates the manipulator to install the head of the piston into the assembly hole of the mobile phone shell, the third clamping jaw releases the piston, and continues to translate the manipulator to assemble the piston in place;

[0065] Step nine: Unloading of assembled mobile phone cases: The mobile phone case conveying unit 800 conveys the assembled mobile phone cases to the unloading unit 804, and the unloading unit 804 pushes qualified mobile phone cases into the mainstream line to enter the next process, and pushes unqualified mobile phone cases into the defective product line.

[0066] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
