[0029] The valve assembly system, the valve assembly system body 43 includes a mounting plate 1, a pipe loading mechanism 2, a conveying mechanism 3, a pipe loading mechanism 4, a tightening transmission mechanism 5 and a material discharge mechanism 6. The pipe loading mechanism 2 loads the required material pipe into the conveying mechanism 3, and the conveying mechanism 3 transfers the material pipe 44-3 to the pipe loading mechanism 4; the valve 44-1 to be installed is tightened by the transmission mechanism 5, and then the material pipe delivered by the conveying mechanism 3 is installed together through the pipe loading mechanism 4, and then the valve assembly 44 after installation is removed by the material discharge mechanism 6 and transferred to the subsequent process.

[0030] The upper tube mechanism 2 of this embodiment is located on the mounting plate 1, and includes a material box 7, a fixed plate 8, a slide groove 9, a column 10, a first gas rod 11, a connecting plate 12, a connecting column 13, a push plate 14 and a push plate driving mechanism.

The push plate driving mechanism includes two columns 10 and a connecting plate 12 mounted on the two columns 10 and capable of sliding up and down along the columns 10, and a first gas rod 11 driving the connecting plate 12 to slide up and down. The connecting plate 12 is connected to the rear push plate through the connecting column 13. The rear fixed plate 8 and the middle fixed plate 8 have slide grooves 9 on both sides. The rear push plate and the middle push plate are connected through the connecting column 13 passing through the slide groove 9, and the middle push plate and the front push plate are connected through the connecting column 13 passing through the slide groove 9. That is, two connecting columns 13 are fixedly connected between two adjacent push plates 14, and the two connecting columns 13 are slidably connected in the slide groove 9. In this embodiment, three fixing plates 8 are arranged up and down, and the height between two adjacent fixing plates 8 decreases successively. The push plate 14 is located behind the fixing plate 8. The distance between two adjacent fixing plates 8 is slightly greater than the thickness of the push plate 14. The height of the push plate 14 is equivalent to the height of the fixing plate 8. The push plate 14 and the fixing plate 8 form a three-level step surface (such as Figure 8 As shown, the height difference of the three steps (T1, T2 and T3) is equal, the T1 step is located at the bottom of the material box 7, the material pipe is placed horizontally in the material box 7, and the material pipe submerges the T1 step. When driven, the push plates 14 of the T1-T3 step are all pushed upward under the drive of the push plate 14 driving mechanism, which makes the material pipe be pushed from the T1 step to the T2 step in sequence, and then further pushed to the T3 step. In this way, the material pipe is pushed up one step in sequence by the push plate 14, and finally enters the next process, that is, the conveying mechanism 3. The feeding mechanism makes the feeding automatic, saves manpower, and improves work efficiency.

[0031] The conveying mechanism 3 includes a bracket 15, a conveyor belt 16 and a first drive motor 17. The bracket 15 is installed on the mounting plate 1. Two drive shafts are arranged in the bracket 15. The conveyor belt 16 is arranged between the two drive shafts. The first drive motor 17 is installed on the bracket 15. The output end of the first drive motor 17 is fixedly connected to one of the drive shafts.

The slider 19 is provided with a third drive motor 22, and the output end of the third drive motor 22 is provided with a positioning rod 23. The mounting plate is provided with a second gas rod 24, and the material lifting frame 25 is provided on the second gas rod 24. Two pairs of third gas rods 26 are arranged in the material lifting frame 25, and a clamping ring 27 is arranged at one end of the third gas rod 26 to facilitate the lifting of the material. Among them, the material lifting frame 25 is U-shaped, and the third gas rod 26 is located on one side of the conveying mechanism 3. The horizontal length of the material lifting frame 25 is longer than the length of the conveyor belt 16 in the conveying mechanism 3. The material pipe is transported to the position of the clamping ring 27, and the material pipe is lifted by the lifting frame 25. At the same time, two pairs of clamping rings 27 clamp the material pipe on the left and right, and then the transmission mechanism 5 is tightened to rotate the material pipe into the valve where the material pipe needs to be installed.

[0033] Among them, a fourth gas rod 28 is provided on the mounting plate 1, and the fourth gas rod 28 is located in front of the lifting frame 25 and above the tightening transmission mechanism 5. A pressure block 29 is installed at one end of the fourth gas rod 28, which is convenient for fixing the valve when installing the pipe.

[0034] The tightening transmission mechanism 5 includes a rotating disk 37, on which a plurality of clamping seats 38 are installed. When the rotating disk 37 rotates, the valve 44-1 with the pressure gauge 44-2 is manually clamped on the clamping seat 38, and then passes through the pre-pressure disk 36 and the clamping disk in sequence. When the clamping seat 38 is rotated to face the material pipe rotating joint in the tightening transmission structure, the tightening transmission mechanism 5 rotates the material pipe to the valve where the material pipe needs to be installed. Specifically, the tightening transmission mechanism 5 includes a support block 31, a support shell 32, a fifth gas rod 33, a fourth drive motor 34, a clamping block 35, a preload plate 36, a rotating disk 37 and a clamping seat 38.

A mechanical claw 42 is arranged on the lower side of the sixth gas rod 41, and a rubber anti-slip is arranged on the surface of the mechanical claw 42, so that the loading and unloading of materials is convenient.

[0036] Working principle:

[0037] The material pipe at the rear end of the fire extinguisher valve is placed in the material box 7, the valve used for assembling the fire extinguisher is placed in the holder 38, and the pressure gauge is pre-installed on the valve in advance. At this time, various components in the control device start to work.

[0038] 1. Control the fourth drive motor 34 at the bottom of the rotating disk 37 to work, so that the fourth drive motor 34 drives the rotating disk 37 to rotate. When the rotating disk 37 rotates to the bottom of one of the support shells 32, the fifth gas rod 33 installed on the support shell 32 descends, so that the pre-pressure disk 36 is pressed on the pressure gauge, so that the pressure gauge can be more stably placed in the knob groove on the valve, and then the fifth gas rod 33 shrinks. At this time, the rotating disk 37 continues to rotate. When the rotating disk 37 rotates to the bottom of another support shell 32, the other fifth gas rod 33 is retracted, thereby controlling the fourth drive motor 34 to descend. At this time, the clamping block 35 is pneumatically controlled to be in an open state. When the fourth drive motor 34 moves to a suitable position, the pressure gauge is located in the middle of the clamping block 35. At this time, the clamping block 35 is closed to clamp the pressure gauge. At this time, the fourth drive motor 34 works to rotate the clamped pressure gauge, so that it is installed in a suitable position. At this time, the pressure gauge is installed.

[0039] 2. Continue to control the rotation of the rotating disk 37. When the rotating disk 37 rotates, the first drive motor 17 and other parts in the conveying mechanism 3 are working at the same time. When the first gas rod 11 is extended, the first gas rod 11 drives the connecting plate 12 to move on the column 10. At this time, the connecting plate 12 drives the three push plates 14 to slide between the three fixed plates 8 through the connecting column 13. When the push plate 14 moves up, the gap between the push plate 14 and the fixed plate 8 can move the pipe up in a step-like manner, so that the pipe can be gradually moved to the conveyor belt 16, and the conveyor belt 16 transports the pipe forward. When the conveyor belt 16 conveys the pipe to one end of the conveyor belt 16, one end of the pipe is located outside the conveyor belt 16 and between two clamping rings 27. At this time, two of the third gas rods 26 are controlled to make the two clamping rings 27 approach each other. The two clamping rings 27 clamp the pipe, and then the second gas rod 24 is controlled to extend, and then the lifting rack 25 moves up. At this time, the pipe is in an ascending state. While rising, the other two clamping rings 27 clamp the material at the same time. At this time, the four clamping rings 27 clamp the material at the same time to ensure the balance and stability of the material.

[0040] 3. When the material rises to a suitable position, the second drive motor 20 is controlled to drive the threaded rod 18 to rotate. At this time, the slider 19 slides on the threaded rod 18. When the slider 19 slides to a suitable position, the positioning rod 23 installed at the output end of the third drive motor 22 is located in the pipe, and with the movement of the slider 19, one end of the pipe is located at one end of the valve (the valve is located at the pipe mouth inside the fire extinguisher), and the slider 19 is pushed forward at the same time. At this time, the fourth gas rod 28 is controlled to be pressed down so that the pressure block 29 is pressed on the valve to ensure the stability of the valve. At the same time, the third drive motor 22 is turned on to rotate the third drive motor 22. At this time, the pipe is screwed into the pipe mouth of the valve, and the equipment assembly is completed.

[0041] 4. Control the fifth drive motor 40 so that the fifth drive motor 40 drives another threaded rod 18 to rotate, thereby controlling the position of the mechanical claw 42. When the mechanical claw 42 moves to a suitable position, control the sixth gas rod 41 so that the sixth gas rod 41 is extended and retracted, thereby cooperating with the mechanical claw 42 to remove the material, and the valve assembly is completed.

[0042] The mutual cooperation of the upper tube mechanism 2, the internal fixing plate 8, the push plate 14 and the first gas rod 11 in the equipment makes the equipment more convenient and quick during assembly, avoiding manual loading, and the parts in the tube loading mechanism 4, the conveying mechanism 3, the tightening transmission mechanism 5 and the unloading mechanism 6 in the equipment cooperate with each other, so that the equipment can use mechanical force instead of manpower when in use, avoiding the need for multiple people to perform multi-step assembly when the product is assembled. The various parts in the equipment cooperate with each other, making the equipment faster to assemble when in use, faster working efficiency, reducing the use of manpower, and reducing the production cost of the product.

[0043] During manual assembly, two employees are needed, one to turn the meter and the other to put on the pipe. The labor intensity is high, and the number of jobs in eight hours is 4000. When using the automatic equipment of the utility model, only one person is needed to operate, the labor intensity is low, and the number of jobs in eight hours is 6000.

[0044] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention.
