Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-2 As shown in the figure, this embodiment proposes a safety valve assembly and testing device. The assembly and testing device includes a machine base 1 and a rotary station 2. The rotary station 2 has multiple workpiece placement positions 3 arranged circumferentially. The assembly and testing device also includes a workpiece detection unit 4, an assembly unit 5, a vision inspection unit 6, a pressing unit 7, an opening detection unit 8, and an unloading unit 9 arranged circumferentially on the side of the rotary station 2. The multiple workpiece placement positions 3 on the rotary station 2 can selectively pass through the workpiece detection unit 4, the assembly unit 5, the vision inspection unit 6, the pressing unit 7, the opening detection unit 8, and the unloading unit 9 in sequence. There are two workpiece placement positions 3 on the rotary station 2, which are used to place the valve body and the sealing ring respectively. The assembly unit 5 is used to assemble the sealing ring with the valve body, the pressing unit 7 is used to press the sealing ring into the valve body, and the opening detection unit 8 is used to detect the opening state of the valve body after sealing.

[0021] This embodiment discloses a safety valve assembly and testing device. A rotating station 2 is set on a machine base 1, with multiple workpiece placement positions 3 arranged circumferentially on the rotating station 2. Each workpiece placement position 3 can hold two workpieces: a sealing ring and a valve body. The workpiece placement positions 3 on the rotating station 2 sequentially pass through a workpiece detection unit 4, an assembly unit 5, a vision inspection unit 6, a pressing unit 7, an opening detection unit 8, and an unloading unit 9. The station before the workpiece detection unit 4 can be used as an empty station for placing the sealing ring and valve body. The workpiece detection unit 4 detects that the workpieces are in place. Then, the assembly unit 5 assembles the sealing ring and valve body. The vision inspection unit 6 detects that the workpieces are assembled correctly. The pressing unit 7 presses the sealing ring into the valve body. The opening detection unit 8 detects whether the valve body can open normally after the pressure reaches a threshold. Finally, the unloading unit 9 removes the assembled and tested valve body from the rotating station 2. This completes the assembly and testing of the safety valve. By integrating the assembly and testing of the safety valve into a single device, both efficiency and assembly reliability are improved.

[0022] The workpiece detection unit 4 includes a first detection bracket 10 and two proximity switches 11. The first detection bracket 10 is disposed on the machine base 1, and the two proximity switches 11 are respectively facing the sealing ring and the valve body on the workpiece placement position 3.

[0023] In this embodiment, a first detection bracket 10 is set on the machine base 1, and two proximity switches 11 are set on the first detection bracket 10. When the workpiece placement position 3 on the rotary station 2 moves to the position of the workpiece detection unit 4, the proximity switches 11 will be triggered if the sealing ring and valve body are in place, so as to determine whether the workpiece is in place.

[0024] The assembly unit 5 includes an assembly bracket 12, an assembly slide plate 13, a first assembly telescopic unit 14, a second assembly telescopic unit 15, and a vacuum suction head 16. The assembly bracket 12 is mounted on the machine base 1. The first assembly telescopic unit 14 is mounted on the assembly bracket 12. The first assembly telescopic unit 14 drives the assembly slide plate 13 to slide horizontally on the assembly bracket 12. The second assembly telescopic unit 15 is mounted on the assembly slide plate 13. The second assembly telescopic unit 15 drives the vacuum suction head 16 to move vertically.

[0025] In this embodiment, by setting an assembly bracket 12 on the machine tool 1, after the workpiece placement position 3 of the rotating station 2 moves to the position of the assembly unit 5, the first assembly telescopic unit 14 drives the assembly slide plate 13 to move above the sealing ring, and the second assembly telescopic unit 15 drives the vacuum suction head 16 to descend to the position of the sealing ring. The vacuum suction head 16 uses negative pressure to adsorb the sealing ring to the end of the vacuum suction head 16. Then the second assembly telescopic unit 15 rises, the first assembly telescopic unit 14 drives the assembly slide plate 13 to move above the valve body, the second assembly telescopic unit 15 descends, the vacuum suction head 16 releases the negative pressure, and the sealing ring is assembled to the corresponding position of the valve body.

[0026] The visual inspection unit 6 includes a second inspection bracket 17 and a visual inspection head 18. The second inspection bracket 17 is disposed on the machine base 1, and the visual inspection head 18 is disposed on the second inspection bracket 17, with the visual inspection head 18 facing the workpiece placement position 3.

[0027] In this embodiment, when the sealing ring moves to the area below the vision inspection unit 6 after the valve body is assembled, the vision inspection head 18 on the second inspection bracket 17 detects whether the sealing ring on the workpiece placement position 3 is installed in place. In a possible implementation, the installation of the sealing ring on the valve body can be compared with a standard image to determine whether the sealing ring is installed in place.

[0028] The pressing unit 7 includes a pressing bracket 19, a pressing telescopic unit 20, and a pressing head 21.

The pressing head 21 has a cylindrical structure and the diameter of the pressing head 21 is the same as that of the sealing ring.

[0029] In this embodiment, after the sealing ring is assembled to the valve body, the rotating station 2 moves it to the bottom of the pressing unit 7. The pressing telescopic unit 20 on the pressing bracket 19 drives the pressing head 21 to descend. The pressing head 21 adopts a cylindrical structure and has the same diameter as the sealing ring. When the pressing head 21 presses down, it presses the sealing ring into the valve body to achieve pre-tightening.

[0030] The opening detection unit 8 includes a third detection bracket 22, a lifting and telescopic unit 23, and a detection cover 24. The third detection bracket 22 is mounted on the machine base 1, and the lifting and telescopic unit 23 is mounted on the third detection bracket 22. The lifting and telescopic unit 23 drives the detection cover 24 to rise and fall, and the detection cover 24 faces the valve body.

[0031] In this embodiment, after the sealing ring is pressed into the valve body, the rotating station 2 moves to below the opening detection unit. The lifting and telescopic unit 23 on the third detection bracket 22 drives the detection cover 24 to descend and cover the valve body in the sealed space. The detection cover 24 can be pressurized to the threshold of the safety valve. If the pressure is released, the safety valve can be opened normally. If the pressure continues to rise, the safety valve cannot be opened normally.

[0032] The unloading unit 9 includes an unloading bracket 25, a transmission belt 26, an unloading slide plate 27, an unloading telescopic unit 28, and a gripper 29. The unloading bracket 25 is mounted on the machine base 1, the transmission belt 26 is mounted on the unloading bracket 25, the unloading slide plate 27 is connected to the transmission belt 26, the transmission belt 26 pulls the unloading slide plate 27 to move horizontally, the unloading telescopic unit 28 is mounted on the unloading slide plate 27, and the gripper 29 is mounted on the telescopic end of the unloading telescopic unit 28.

[0033] In this embodiment, after the inspection is completed, the rotary station 2 moves to the unloading unit 9. A transmission belt 26 is installed on the unloading bracket 25, driving the unloading slide plate 27 to move horizontally, bringing the unloading telescopic unit 28 above the valve body. The unloading telescopic unit 28 lowers the gripper 29 to the valve body. The gripper 29 can be a pneumatic three-jaw structure, clamping the valve body. The unloading telescopic unit 28 lifts the valve body, and the transmission belt 26 drives the slide plate to the unloading side. The unloading telescopic unit 28 then lowers, and the gripper 29 unloads the valve body. It should be noted that the transmission belt 26 needs to be driven by a motor or a slide rail, with movement achieved by a telescopic drive component.

[0034] It should be noted that the telescopic units in the above embodiments can all be implemented using telescopic components such as cylinders or electric cylinders, which is not a limitation.

[0035] The assembly and testing equipment also includes an unloading conveyor belt 30 and a recycling bin 31.
