Description

Technical Field

[0001] This utility model relates to the technical field of valve body assembly equipment, specifically to an automatic assembly mechanism for valve bodies. Background Technology

[0002] Currently, valve body assembly relies on manual material loading and assembly, resulting in poor equipment flexibility and an inability to adapt to the production of multi-specification products. In addition to low efficiency, manual operation also introduces uncontrollable factors into the production process.

[0003] The assembly of the valve body and valve plate mainly relies on the following methods: (a) Purely manual or semi-manual assembly method This is the most traditional method, where workers manually complete processes such as oiling, aligning, and screwing the valve body.

[0004] Pain Point 1: Low efficiency and limited production capacity. Manual operation is slow, prone to fatigue, and difficult to increase production cycle time, making it impossible to meet the needs of large-scale mass production.

[0005] Pain Point 2: Poor product quality consistency. The amount and location of oil applied manually are difficult to control precisely; the torque of screw-on joints depends entirely on feel, resulting in inconsistent product sealing and reliability, and a high defect rate.

[0006] Pain Point 3: High Labor Costs. With the continuous rise in labor costs, production models that rely on a large workforce face enormous cost pressures.

[0007] Pain Point 4: Inefficient workflow. Processes such as loading, oiling, assembly, and unloading are usually scattered and require manual handling and transfer, resulting in low logistics efficiency and easy damage to workpieces.

[0008] (ii) Simple automated or semi-automated equipment To address the issue of purely manual labor, some simple automated equipment may exist on the market, such as a single automatic oiling machine or a simple splicing machine.

[0009] Pain Point 1: Low integration, forming "automation islands". The equipment for each process is independent, and manual loading, unloading and transfer are still required between them, which cannot form a continuous automated flow line and has limited overall efficiency improvement.

[0010] Pain Point 2: Lack of Process Quality Control. Simple automated equipment typically only performs actions and lacks detection capabilities. For example, after applying oil, it's impossible to determine whether the oil level is up to standard. Defective products will flow into subsequent processes, ultimately leading to the scrapping of the entire product and causing waste.

[0011] Pain Point 3: Poor flexibility and adaptability. This type of equipment is usually designed for specific products. Once the product specifications change (such as changes in valve body size or thread specifications), the equipment is difficult to modify and may even become unusable.

[0012] Pain Point 4: Insufficient Positioning Accuracy. During the assembly process, the simple mechanical structure makes it difficult to ensure precise alignment between the valve body and the valve plate holes, which can easily lead to misalignment, jamming, or thread damage. Summary of the Invention

[0013] This invention addresses the shortcomings of existing technologies by providing an automated assembly mechanism for valve bodies, characterized by its compact structure, high efficiency, and stable operation. The entire system, through the collaborative work of multiple workstations, robotic arms, conveying modules, and vision inspection units, achieves unmanned, high-precision, and high-efficiency automated production from raw materials to finished products.

If the oiling is unsatisfactory, the valve is placed on the NG tray. If the oiling is satisfactory, the valve is placed at the valve transfer station.

[0019] Preferably, a valve waiting-to-process workstation cabinet is provided between the feeding line and the frame. The valve waiting-to-process workstation cabinet is used to store valve bodies to be processed, serving as a buffer and material management function.

A pair of valve body lateral movement modules 12 are mounted at the front end of the valve transfer station 14, each equipped with a valve body tooling seat 9. Valve plates are loaded using the valve body tooling seats 9. The valve body lateral movement modules 12 transport the valve plates to the side of the valve transfer station 14. The vacuum suction rotators 13 pick up the valves from the valve transfer station 14 and place them onto the valve plates via robotic arms II 11 and III 15.

Valve waiting-to-process workstation cabinets 3 are located between the loading lines 2 and the frame 7. An oiling assembly 10 is provided between the loading line 2 and the valve body transverse module 12. The oiling assembly 10 includes an oiling seat 19, on which a valve oiling fixture 18 is provided. An oiling transverse cylinder 17, which drives the displacement of the valve oiling fixture 18, is located inside the oiling seat 19. An oiling machine 20, which applies oil to the valve on the valve oiling fixture 18, is also provided on the oiling seat 19.

An NG tray 8 is located on the side of the oiling assembly 10, and industrial cameras 6 are located between the oiling assembly 10 and the transverse cylinder I1 on both sides. After the valve completes the oiling operation on the oiling assembly 10, the cylinder gripper I4 picks up the valve and moves it to the industrial camera 6. If the oiling is unsatisfactory, the valve is placed on the NG tray 8. If the oiling is satisfactory, the valve is placed on the valve transfer station 14. A material handling assembly 16 is located on the side of the frame 7, at the end of the valve body transverse module 12.

[0039] Sorting: Qualified products: are placed at valve transfer station 14, awaiting assembly.

[0040] Non-conforming products: Placed in NG tray 8 and removed from the production line. Ensuring each product meets stringent quality standards reduces defect rates and enhances brand reputation.

[0041] Valve plate supply: At the same time, the valve body transverse module 12 transports the valve body tooling seat 9, which is loaded with the valve plate, to the assembly station.

[0042] Assembly: Robotic arms II 11 and III 15 pick up qualified valve bodies from the valve transfer station and place them on the valve plate. The vacuum suction rotator 13 at the front end then rotates, tightening the valve body onto the valve plate, completing the assembly.

[0043] Unloading: The assembled finished product moves to the end with the tooling base. Driven by the finished product transverse module 23 and the lead screw motor 25, the cylinder gripper II 22 of the picking component 16 picks up the finished product and moves it out of the production line.

[0044] In summary, this automated assembly mechanism for valve bodies features a compact structure, high efficiency, and good operational stability. The entire system, through the collaborative work of multiple workstations, robotic arms, conveying modules, and vision inspection units, achieves unmanned, high-precision, and high-efficiency automated production from raw materials to finished products.
