Technical Field

[0001] This utility model relates to the technical field of valve core assembly, specifically to a valve core assembly device. Background Technology

[0002] Valve core assembly refers to the process of assembling and installing the valve core, sealing ring, nameplate and other supporting parts into the valve body according to the design requirements through positioning, assembly, riveting and testing, so as to form a complete valve core assembly. Its core purpose is to ensure that the parts fit together precisely so that the assembled valve core can perform sealing, fluid control and other functions normally. However, current valve core assembly relies heavily on manual operation, resulting in low assembly efficiency and difficulty in guaranteeing accuracy, which cannot meet the needs of large-scale production. Existing assembly equipment often faces several shortcomings: First, sealing rings tend to accumulate during loading and are not accurately positioned during assembly, affecting the sealing effect; second, the valve core and valve body are prone to misalignment during assembly due to the tight fit, requiring additional manual adjustment; third, nameplate loading has poor compatibility, riveting angles are prone to deviation, and there is a lack of an efficient multi-station inspection mechanism, making it difficult to simultaneously ensure the assembly quality and overall production efficiency at each stage. Therefore, this utility model provides a valve core assembly device to solve the problems mentioned above. Utility Model Content

After the equipment starts, the clamping cylinder and positioning mechanism fix the trolley. The loading servo module drives the camera and grippers. The camera takes pictures of the valve body, positions it, and identifies the model. The grippers pick up the valve body and accurately place it on the fixture tray of the conveyor line. The tray moves with the conveyor line to each station. In the multi-station assembly stage, the sealing rings are assembled: a direct vibration + soft vibration mechanism disperses the stacked sealing rings, and the camera above takes pictures to position the sealing rings. The servo module drives four sets of sealing ring picking mechanisms, including the sealing ring... The suction nozzle 202 precisely picks up the material, and then, based on the camera positioning, inserts the sealing ring into the sealing ring hole of the valve body. The valve body positioning mechanism 203 prevents displacement through the positioning pin. The sealing ring that is not installed in place is blown into the receiving box 2032 by the air blowing component 2033. Valve core assembly: The double tray alternating feeding mechanism continuously supplies the valve core. The servo module gripper and brass clip fingers prevent damage when gripping the valve core. The camera takes a picture to determine whether it needs to be flipped. The guide sleeve moves to the unloading position, and the valve core falls into the valve body through the guide sleeve. The direct vibrator 30102 assists the valve core to slide to the accurate position through high-frequency vibration. like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the process is as follows: Nameplate riveting: The dual-fixture feeding mechanism supplies nameplates, the nameplate transfer mechanism 401 drives the suction mechanism to pick up the nameplates, and the air nozzle blows away the adhesive nameplates; after the camera takes pictures and corrects the angle of the nameplates, they are accurately placed above the valve body, and the rivet gun transfer mechanism drives the rivet gun to complete the riveting. The valve body flipping mechanism, including the electromagnet 4061 to prevent falling, adjusts the valve body posture as needed; Steel stamping: The fixture tray flows to the steel stamping station 5, the second lifting cylinder 504 lifts the tray, and the two sides are fixed in position by hard limit; the steel stamping cylinder 502 drives the steel stamp to adhere to the nameplate, and the stamping mechanism stamps the number. After completion, the tray is reset and transferred; Unloading and sorting stage: The fixture tray arrives at the unloading station 6, the first lifting cylinder 2021 lifts the tray, and the NG camera 601 takes pictures to check whether the finished products are qualified; qualified parts are placed into the unloading trolley by the servo module gripper, and unqualified parts are moved to the NG tray 603; the full material trolley is manually replaced to complete the entire valve core assembly process.
