[0079] The rubber grabbing and assembling mechanism with the rubber piece is used to move and align with the support rod, and the rubber grabbing and assembling mechanism removes half of the rubber piece and installs the plastic gasket into the rubber piece at the same time;

[0080] The assembled rubber gripping assembly mechanism is moved to the lower material mechanism, and the stripping component slides the assembled sealing ring along the material drop chute into the storage box, completing the assembly of the faucet sealing ring. The above actions are repeated to continue the assembly of the next group.

[0081] The use principle of the present invention is as follows: the corresponding rubber parts are manually placed on the rubber part feeding mechanism 6, and the corresponding plastic washers are placed on the plastic washers vibration feeding mechanism 5. The rubber part feeding mechanism 6 and the plastic washers vibration feeding mechanism 5 continuously transport the rubber parts and the plastic washers to the corresponding second feeding trough 62 and the feeding trough 53. At this time, the rubber feeding assembly 23 moves to the top of the feeding trough 53 under the action of the first driving source 22 and grabs the plastic washers. At the same time, the opening mechanism 3 moves to the bottom of the discharge end of the second feeding trough 62. Then, under the action of the sixth power source 31, the grabbing component 343 is inserted into the rubber part and opened. At this time, the opened diameter is larger than the outer diameter of the plastic washers and then stops. The opening mechanism 3 moves in the reverse direction to push out the rubber feeding assembly 23 with the rubber parts, and the first driving source 22 Working in reverse, the rubber loading assembly 23 is pushed to the top of the opening mechanism 3; then the rubber piece grabbing and unloading assembly 34 pushes the opening mechanism 3 onto the rubber loading assembly 23, and the plastic gasket is placed on the lower material mechanism 4 during the pushing process. Finally, the first driving source 22 pushes the rubber loading assembly 23 to the top of the lower material mechanism 4. At this time, the plastic gasket grabbing component 234 on the rubber loading assembly 23 moves down, and the lower material mechanism 4 rises to complete the docking. Thereafter, the stripping component 2354 pushes the rubber piece down by half the height to complete the assembly of the plastic gasket into the rubber piece. After the assembly, the lower material mechanism 4 descends to its initial position, and the stripping component 2354 pushes the sealing ring away from the plastic gasket grabbing component 234. The pushed-away sealing ring is collected by the material mechanism 4, thus completing the assembly of a sealing piece.

[0082] To sum up, the present invention uses the spreading mechanism to spread the rubber parts and then transfer them to the rubber grabbing assembly mechanism. During the transfer process, the plastic gasket grabbing components work at the same time. Finally, the rubber grabbing assembly mechanism cooperates with the material mechanism to complete the assembly and assembly collection, which effectively solves the technical problems of high labor intensity, low production efficiency, and high production cost of existing workers. At the same time, after adopting the above technical scheme, the sealing ring assembly efficiency can reach 6120 pieces per hour, which is conducive to the large-scale promotion and use of German throat clamps. In addition, the rubber grabbing assembly mechanism adopts the fourth driving source, the fifth driving source and the stripping component. Specifically, the fourth driving source is used for the first stripping and assembly, and then the fifth driving source is used for the second time to push the stripping component to push the assembled seal out. The two pushes do not interfere with each other and are completed on the same structure, so that the overall submission is streamlined, while the assembly efficiency can be guaranteed, thereby further improving the efficiency.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, the technicians can still modify or replace the specific implementation mode of the present invention with equivalents, but these modifications or changes do not deviate from the scope of protection of the pending claims of the present invention.
