[0035] The working principle of the present invention is: the mobile phone key is a stepped columnar part, and its column body is provided with an annular groove. During processing, the sealing ring needs to be installed in the annular groove of the mobile phone key, and then the mobile phone key is pressed onto the mobile phone HSG. The mainstream line 10 of the present invention is used to transport the carrier loaded with the mobile phone HSG.

[0036] When the present invention is in use, the HSG carrier is transferred to the assembly station and lifted to the assembly station by the lifting cylinder. At the electric turntable 2, the mobile phone keys are first loaded by the key feeding mechanism 5, and the key feeding manipulator 4 cooperates with the key clamping claw cylinder 701 to clamp the mobile phone keys at the discharge end of the key feeding mechanism 5 and transfer them to the corresponding key elastic carrier 3 (the key elastic carrier 3 is now in a loose state by pressing the push pin 302 by the loosening cylinder 15), and then the loosening cylinder 15 piston rod is retracted, and the clamp 306 is reset to clamp the mobile phone keys, and then the key elastic carrier 3 is transferred to the sealing At the ring assembly station, the sealing ring is fed by the sealing ring feeding mechanism 6, and the sealing ring set manipulator 8 drives the supporting inner rod 803 to the discharging end of the sealing ring feeding mechanism 6 to pick up the material, and the supporting inner rod 803 is driven to descend and extend into the center of the sealing ring by the opening cylinder 801. Under the action of the inclined surface of the supporting inner rod 803, the sealing ring will be tightened on the supporting inner rod 803. After the material picking is completed, the piston rod of the opening cylinder 801 is retracted, and the supporting inner rod 803 is retracted into the picking sleeve 802. Since the degree to which the sealing ring is stretched by the supporting inner rod 803 is greater than the degree to which the sealing ring is stretched by the picking sleeve 802, During the retraction process of 803, the sealing ring will be transferred from the supporting inner rod 803 to the fork claw at the lower end of the material taking sleeve 802 under the obstruction of the material returning push plate 805. Then the material taking sleeve 801 moves to the top of the mobile phone key and descends. At this time, the lower end of the fork claw corresponds to the annular groove on the mobile phone key, and the material returning push plate 805 is driven to descend by the material returning cylinder 804, pushing the sealing ring downward so that it is transferred from the fork claw of the material taking sleeve 802 to the mobile phone key to complete the assembly of the sealing ring. After the assembly of the sealing ring is completed, it is inspected at the first CCD camera 12 to detect whether the sealing ring set position is qualified. For qualified The product continues to flow to the finished product picking station, and after being unclamped by the unclamping cylinder 15, the lifting cylinder 203 drives the rotating cylinder 201 and the reversing clamping claw cylinder 202 to descend and clamp the finished mobile phone keypad product, and then rises again after the rotating cylinder 201 rotates and reverses. Subsequently, the finished mobile phone keypad product is transferred to the corresponding installation position of the mobile phone HSG through the finished product assembly robot 7 and the product clamping claw cylinder 701, and the mobile phone keypad is pressed onto the mobile phone HSG through the assembly cylinder 702 to complete the assembly. The assembled mobile phone HSG is subsequently transferred to the third CCD camera 14 for visual inspection to detect whether the mobile phone keypad is installed normally.
