Description
Technical Field
[0001] This invention relates to the technical field of one-way valve assembly equipment, and more specifically to a fully automatic one-way valve assembly and welding equipment. Background Technology
[0002] The existing cylindrical one-way valve structure includes a valve disc, a threaded valve body, and a cylindrical valve seat. The valve seat is coaxially mounted on one end of the valve body. The valve disc consists of a disc with a column and a plug disc with a column. The plug disc is shaped like an inverted funnel, and the column is located at the small opening of the plug disc. The connection is achieved by the column of the plug disc fitting onto the column of the disc. One-way flow is achieved by whether the spherical surface of the plug disc blocks the valve seat. However, the assembly of all the above components is done manually, which results in low assembly efficiency. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a fully automatic assembly and welding equipment for one-way valves, which solves the problem of low efficiency in manual assembly by integrating the automatic conveying, assembly, and welding functions of the disc, valve body, and plug disc.
[0004] To achieve the above objectives, the present invention provides the following technical solution: including a frame, a disc conveying device, a valve body conveying device, and a plug disc conveying device all mounted on the frame, and an assembly device. The disc conveying device, the valve body conveying device, and the plug disc conveying device are arranged sequentially around the assembly device on the frame to convey the disc, the valve body, and the plug disc to the assembly device. The assembly device assembles the valve body onto the disc and then assembles the plug disc onto the disc.
[0005] As a further improvement of the present invention, the disc conveying device includes a disc funnel, a disc conveyor belt, and a disc vibrating plate. The disc vibrating plate is connected to the assembly device via a transmission track. One end of the disc conveyor belt is positioned below the disc funnel, and the other end is positioned above the disc vibrating plate, so as to convey the disc leaking from the disc funnel to the disc vibrating plate, and then to the assembly device via the disc vibrating plate.
[0006] As a further improvement of the present invention, the valve body conveying device includes a storage tank, a pusher plate, and a vibrating track. One end of the vibrating track is positioned above the storage tank, and the other end extends to the assembly device. The side wall of the vibrating track is connected to the storage tank via a return track. The storage tank is inclined towards the side wall of the vibrating track to form a conveying wall. The upper side of the conveying wall extends to the vibrating track, and the lower side extends to the bottom of the storage tank. The pusher plate is slidably positioned on the conveying wall. By moving up and down, the valve body in the storage tank is conveyed upward to the vibrating track. The vibrating track conveys the valve body facing the correct direction to the assembly device through vibration, and conveys the valve body facing the wrong direction to the return track and then into the storage tank.
[0007] As a further improvement of the present invention, the stopper disc conveying device includes a stopper disc funnel, a stopper disc conveyor belt, and a stopper disc vibrating plate. The stopper disc vibrating plate is connected to the assembly device via a transmission track. One end of the stopper disc conveyor belt is positioned below the stopper disc funnel, and the other end is positioned above the stopper disc vibrating plate, so as to transport the stopper disc leaking from the stopper disc funnel to the stopper disc vibrating plate, and then to the assembly device via the stopper disc vibrating plate.
[0008] As a further improvement of the present invention, the assembly device includes an assembly turntable mounted on a frame, and a disc assembly robot, a valve body assembly robot, a plug disc assembly robot, a pressing cylinder, a welding head, and a discharge robot distributed circumferentially around the assembly turntable on the frame. A plurality of clamping slots are evenly distributed on the upper surface of the assembly turntable near the circumference of the circle. As the assembly turntable rotates, the clamping slots sequentially pass through the disc assembly robot, the valve body assembly robot, the plug disc assembly robot, the pressing cylinder, the welding head, and the discharge robot. During assembly, the disc conveyor transports the disc to below the disc assembly robot, which then clamps the disc and places it into the fixture slot. The valve body conveyor transports the valve body to below the valve body assembly robot, which then grasps the valve body, places it into the fixture slot, and assembles it with the disc. The stopper disc conveyor transports the stopper disc to below the stopper disc robot, which grasps the stopper disc, places it into the fixture slot, and assembles it with the valve body and the disc. Afterward, the valve body is press-fitted by a press cylinder, then welded by a welding head, and finally discharged by a discharge robot.
[0009] As a further improvement of the present invention, the stopper assembly robot includes a stopper frame, a gripping cylinder that can be moved horizontally on the stopper frame, and a gripping head disposed at the lower end of the gripping cylinder push rod. A connecting plate is provided above the gripping cylinder, one end of which is connected to the push rod of the gripping cylinder, and the other end is fixed with a vertical measuring rod. When the gripping cylinder pushes down to drive the gripping head into the stopper, the measuring rod descends and inserts into the valve body in the clamping groove. The beneficial effects of this invention lie in achieving fully automated assembly and welding of the one-way valve by integrating an automatic conveying device and an assembly device for the disc, valve body, and plug disc, significantly improving assembly efficiency and solving the problem of low efficiency in manual assembly. The equipment has a high degree of automation, with each device working collaboratively to ensure assembly accuracy and consistency. The structural design of the disc conveying device, valve body conveying device, and plug disc conveying device ensures orderly and accurate conveying of each component; the rotary structure of the assembly device enables continuous multi-station operation, further improving production efficiency; and the measuring rod design of the plug disc assembly robot ensures precise matching between the plug disc and the valve body, improving assembly quality.

Detailed Implementation
[0011] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0012] Reference Figure 1 As shown, the fully automatic assembly and welding equipment for one-way valves in this embodiment includes a frame 1, a disc conveying device 2, a valve body conveying device 3, and a plug disc conveying device 4, all mounted on the frame 1, and an assembly device 5. The disc conveying device 2, valve body conveying device 3, and plug disc conveying device 4 are arranged sequentially around the assembly device 5 on the frame 1 to convey the disc, valve body, and plug disc to the assembly device 5. The assembly device 5 assembles the valve body onto the disc, and then assembles the plug disc onto the disc. The disc, valve body, and plug disc are automatically conveyed to the assembly device 5 through their respective conveying devices without manual intervention. The assembly device 5 completes the assembly of the valve body with the disc and the plug disc with the disc, achieving fully automatic operation, effectively improving assembly efficiency, and solving the problem of low efficiency in manual assembly.
[0013] Reference Figure 1 As shown, the disc conveying device 2 further includes a disc funnel 21, a disc conveyor belt 22, and a disc vibrating plate 23. The disc vibrating plate 23 is connected to the assembly device 5 via a transmission track. One end of the disc conveyor belt 22 is positioned below the disc funnel 21, and the other end is positioned above the disc vibrating plate 23, to transport the discs leaking from the disc funnel 21 to the disc vibrating plate 23, and then to the assembly device 5 via the disc vibrating plate 23. The disc funnel 21 stores the discs, the disc conveyor belt 22 transports them to the disc vibrating plate 23, and the disc vibrating plate 23 sorts and orients the discs to ensure accurate delivery of the discs to the assembly device 5, thereby improving the stability and efficiency of the conveying process.
[0014] Reference Figure 2As shown, the valve body conveying device 3 further includes a storage tank 31, a pusher plate 32, and a vibrating track 33. One end of the vibrating track 33 is positioned above the storage tank 31, and the other end extends to the assembly device 5. The side wall of the vibrating track 33 is connected to the storage tank 31 via a return track. The storage tank 31 is inclined towards the side wall of the vibrating track 33 to form a conveying wall. The upper side of the conveying wall extends to the vibrating track 33, and the lower side extends to the bottom of the storage tank 31. The pusher plate 32 is slidably mounted on the conveying wall. By moving up and down, the valve body in the storage tank 31 is conveyed upward to the vibrating track 33. The vibrating track 33 conveys the valve body facing the correct direction to the assembly device 5 through vibration, and conveys the valve body facing the wrong direction to the return track and then into the storage tank 31. The pusher plate 32 pushes the valve body to the vibration track 33. The vibration track 33 selects the valve bodies that are facing the correct direction, and the incorrect valve bodies are returned to the storage tank 31. This ensures that the valve bodies delivered to the assembly device 5 are in the correct direction, improves the assembly accuracy, and reduces the scrap rate. In this embodiment, the pusher plate 32 adopts a stacked method, and the valve bodies are conveyed row by row by using the staggered sliding method between the multiple plates.
[0015] Reference Figure 1 As shown, the stopper disc conveying device 4 further includes a stopper disc funnel 41, a stopper disc conveyor belt 42, and a stopper disc vibrating plate 43. The stopper disc vibrating plate 43 is connected to the assembly device 5 via a transmission track. One end of the stopper disc conveyor belt 42 is positioned below the stopper disc funnel 41, and the other end is positioned above the stopper disc vibrating plate 43, so as to convey the stopper discs leaking from the stopper disc funnel 41 to the stopper disc vibrating plate 43, and then convey them to the assembly device 5 via the stopper disc vibrating plate 43. The stopper disc funnel 41 stores the stopper discs, and the stopper disc conveyor belt 42 conveys them to the stopper disc vibrating plate 43. The stopper disc vibrating plate 43 sorts and orients the stopper discs to ensure that they are accurately conveyed to the assembly device 5, thereby improving the conveying efficiency.
[0016] Reference Figure 1As shown, the assembly device 5 further includes an assembly turntable 51 mounted on a frame 1. Around the assembly turntable 51, the frame 1 is circumferentially distributed a disc assembly robot 52, a valve body assembly robot 53, a stopper disc assembly robot 54, a pressing cylinder 55, a welding head 56, and a discharge robot 57. Several clamping slots 511 are evenly distributed on the upper surface of the assembly turntable 51 near its circumference. As the assembly turntable 51 rotates, the clamping slots 511 sequentially pass through the disc assembly robot 52, the valve body assembly robot 53, the stopper disc assembly robot 54, the pressing cylinder 55, the welding head 56, and the discharge robot 57. During assembly, the disc conveyor 2 transports the disc to below the disc assembly robot 52, which clamps the disc and places it into the fixture slot 511. The valve body conveyor 3 transports the valve body to below the valve body assembly robot 53, which grasps the valve body and places it into the fixture slot 511, assembling it with the disc. The stopper disc conveyor 4 transports the stopper disc to below the stopper disc robot 54, which grasps the stopper disc and places it into the fixture slot 511, assembling it with the valve body and the disc. Then, the stopper disc is pressed by the press cylinder 55, welded by the welding head 56, and finally discharged by the discharge robot 57. The rotation of the assembly turntable 51 enables continuous multi-station operation. The disc assembly robot 52, valve body assembly robot 53, and plug disc assembly robot 54 work together to complete the assembly. The pressing cylinder 55 completes the pressing, the welding head 56 completes the welding, and the unloading robot 57 completes the unloading, which greatly improves production efficiency and ensures the continuity and consistency of the operation of each station.
[0017] Reference Figure 3 As shown, the stopper disc assembly robot 54 further includes a stopper disc frame 541, a gripping cylinder 542 movably mounted on the stopper disc frame 541, and a gripping head 543 located at the lower end of the push rod of the gripping cylinder 542. A connecting plate 544 is provided above the gripping cylinder 542. One end of the connecting plate 544 is connected to the push rod of the gripping cylinder 542, and the other end is fixed with a vertical measuring rod. When the gripping cylinder 542 pushes down to drive the gripping head 543 into the stopper disc, the measuring rod descends and inserts into the valve body within the clamping groove 511. The insertion of the measuring rod into the valve body ensures precise fit between the stopper disc and the valve body, avoids assembly deviations, and improves assembly quality.
