[0016] A method for using a positioning auxiliary device for water meter movement assembly equipment comprises the following steps:

[0017] S1. The robotic arm assembly changes the position of the grabbing assembly, grabs the movement accessories to the top of the water meter model with the robotic claw, and then lowers the accessories into the water meter model. One of the robotic claws is used to press down the movable ring. During this process, the electric telescopic rod is synchronously controlled to drive the support rod to insert the docking pipe into the extended straight pipe.

[0018] S2. After the accessory passes through the positioning ring, it contacts the water absorption component. By pressing down the movable end, the vertical pipe is pushed into the interior of the fixed pipe, so that the vertical pipe, the fixed pipe and the water delivery pipe are connected. Then, the mechanical claw on the movable ring is removed to lock the fixed pipe and the vertical pipe.

[0019] S3, release the water in the water tank, the water enters the water discharge pipe from the transmission pipe and flows out, then flows along the surface of the component into the vertical pipe, and finally enters the water delivery pipe through the fixed pipe;

[0020] S4, starting the freezing platform to freeze the water in the water absorption component, and freezing the components by freezing the water, so that the components are fixed in the water meter model;

[0021] S5. After the fixation is completed, the grabbing assembly releases the parts, grabs new parts to the top of the support plate for positioning and assembly, and repeats steps S1, S2, S3 and S4;

[0022] S6. After the assembly is completed, close the freezing platform and let the ice thaw naturally. The thawed water will flow out from the docking pipe. After removing the assembled movement, use the mechanical claw to press down the movable ring again. The rebound of the first tension spring and the second tension spring can pop the vertical pipe out of the fixed pipe.

[0023] Preferably, in step S3, the step of fixing the component above the water absorbing assembly further comprises the following steps:

[0024] S41. Water flows into the water pipe through the fixed pipe. Since the water pipe is in direct contact with the water meter model, and the freezing platform will lower the temperature of the water meter model, the water remaining in the water pipe and the vertical pipe will be frozen, and the water on the surface of the parts will also be gradually frozen, ultimately achieving the purpose of fixing the parts;

[0025] S42, the water in the fixed pipe freezes from bottom to top in sequence, and the water delivery is stopped after the water on the surface of the model freezes to prevent the water in the drain pipe from freezing, and the grabbing component is moved away from above the water meter model.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present invention, water absorption components that are distributed in an annular manner and are equally spaced are arranged in the support plate, and each water absorption component corresponds to a coordinate point, which is convenient for rapid positioning. In the process of assembly, it plays a role of auxiliary positioning. At the same time, the method of freezing parts is used to fix the parts after the positions of the parts are determined. The freezing method can fix the parts in the water meter model. Even if the positions of the subsequent devices change, it will not affect the states of the parts, and the stability of the parts can be maintained for a long time. At the same time, the parts in the frozen state can avoid the problem of two parts colliding with each other and affecting the positioning accuracy, so that the movement can be assembled at a faster speed, which helps to improve the assembly speed.

[0028] 2. In the present invention, a first plugging head and a second plugging head are provided in the water absorption component. After the components enter the water meter model, they will push the movable end head to move downward. Since each movable end head corresponds to a coordinate point, when the movable end head is triggered, it means that the components are deployed at the coordinate point, which is convenient for improving the positioning accuracy. Moreover, after the first plugging head and the second plugging head come into contact with each other, the flow channel of water can be opened, providing operational feasibility for subsequent freezing.

[0029] 3. In the present invention, the water tank is arranged on the auxiliary force arm, and starts to release water after the component contacts the water absorption component. The water flows downward along the direction of the component under the action of gravity. This method can ensure that the water can completely cover the surface of the component. In the subsequent freezing process, the component can be fully fixed, thereby improving the stability of the component. In addition, the water released when assembling another component can contact the ice cubes on the other component. By allowing the water to contact the ice cubes, the subsequent freezing speed is accelerated, and the ice cubes on the surfaces of the two components can be fused together, further improving the stability of the component.

[0030] 4. In the present invention, the first plugging head is installed in the vertical pipe through the first telescopic rod, and the second plugging head is installed in the fixed pipe through the second telescopic rod. In the initial state, the two plugging heads are respectively supported by the first tension spring and the second tension spring to ensure that the movable end can be triggered normally. The movable ring is used to lock the vertical pipe and the fixed pipe to ensure that there will be no rebound when carrying parts. After removing the movement, pressing the movable ring again can reset the movable end, which can not only ensure the stability of the supporting parts, but also can be used multiple times.

[0046] The model assembly 4 includes a water meter model 41 and a positioning ring 45. A positioning rod 43 is fixedly installed at the bottom of the water meter model 41. The positioning rod 43 is plugged into the interior of the freezing platform 3. A water delivery pipeline 47 is fixedly installed inside the water meter model 41. The positioning ring 45 is fixedly installed on the top of the water meter model 41. A support plate 46 and a water absorption component 8 inside the positioning ring 45 are fixedly installed on the inner wall of the positioning ring 45. The water absorption component 8 is connected to the water delivery pipeline 47.

[0047] The water absorption assembly 8 includes a movable end 81, a vertical pipe 84, a fixed pipe 82, a first plugging head 810 and a second plugging head 817. The vertical pipe 84 is fixedly installed at the bottom of the movable end 81, the fixed pipe 82 is fixedly installed inside the support plate 46, one end of the vertical pipe 84 is inserted into the inside of the fixed pipe 82, the first plugging head 810 is inserted into the inside of the movable end 81, and the second plugging head 817 is inserted into the inside of the fixed pipe 82.

[0048] In this embodiment, the mechanical arm assembly 5 is installed at one end of the operating platform 1, and the freezing platform 3 is installed at the other end of the operating platform 1. When assembling the movement, the mechanical arm assembly 5 drives the grabbing assembly 6, and the grabbing assembly 6 uses three fingers to grab the parts. The mechanical arm assembly 5 then controls the grabbing assembly 6 to move to the model assembly 4, and then puts the parts into the water meter model 41;

[0049] The water meter model 41 is a one-to-one replica of the shape of the water meter, and a support plate 46 is fixedly installed inside the water meter model 41. At the same time, a circular positioning ring 45 is arranged on the top of the water meter model 41. The positioning ring 45 and the support plate 46 form a coordinate structure. Each water absorbing component 8 installed on the support plate 46 represents a coordinate point, which is used to assist in determining the position of the components;

[0050] When lowering the parts, the weight of the parts will press down the movable end 81, pushing the vertical pipe 84 into the fixed pipe 82. During this process, the first plugging head 810 and the second plugging head 817 will push each other, the first plugging head 810 will enter the vertical pipe 84, and the second plugging head 817 will enter the fixed pipe 82, so that the vertical pipe 84 is connected with the fixed pipe 82.

[0051] After connecting the vertical pipe 84 and the fixed pipe 82, the grabbing assembly 6 starts to release water, and the water flows into the vertical pipe 84 along the parts, and then enters the water supply pipe 47 in the water meter model 41 along the fixed pipe 82. At this time, the freezing platform 3 is started to freeze the water in the pipe, and all the water in the pipe is frozen into ice. Because the grabbing assembly 6 is above the parts, the water will completely cover the surface of the parts in the process of flowing downward, and the freezing treatment will cause an ice layer to form on the surface of the parts, and the water remaining in the vertical pipe 84 and the fixed pipe 82 will freeze into icicles, which will play a role in assisting the support of the upper parts, thereby completing the positioning and fixation of a part, and then grab a new part and repeat the above steps.

The other end of the second tension spring 818 is fixedly connected to the inside of the second plugging head 817, the connecting block 83 is fixedly installed in the inside of the support plate 46, a positioning hole 812 is opened in the fixed pipe 82, a limiting bead 813 is arranged in the positioning hole 812, an annular convex strip 86 is fixedly installed on the outer wall of the vertical pipe 84, a receiving groove 87 is arranged on one side of the annular convex strip 86, a movable ring 85 is sleeved on the top of the fixed pipe 82, an anti-slip ring 819 is fixedly installed on the top of the fixed pipe 82, two annular grooves 814 are opened on the outer wall of the fixed pipe 82, a third tension spring 820 is fixedly connected to the inner wall of the movable ring 85, and the other end of the third tension spring 820 is fixedly connected to the outer wall of the fixed pipe 82.

[0054] In this embodiment, the first plugging head 810 is installed on the first filter plate 88 in the vertical pipe 84 through the first telescopic rod 89, and a first tension spring 811 is also connected between the first filter plate 88 to ensure that the first plugging head 810 can block the vertical pipe 84 in the initial state. The second plugging head 817 is installed on the second filter plate 815 through the second telescopic rod 816, and a second tension spring 818 is also connected between the second filter plate 815. The existence of the first filter plate 88 and the second filter plate 815 is used to determine the positions of the first plugging head 810 and the second plugging head 817, and also to ensure the normal flow of water. When the part presses down the movable end, the first plugging head 810 and the second plugging head 817 contact each other, and at the same time squeeze the first tension spring 811 and the second tension spring 818, so that the vertical pipe 84 is connected to the fixed pipe 82;

[0055] The fixed pipe 82 is installed in the support plate 46 through the connecting block 83 and is connected to the water delivery pipe 47 below. A limiting bead 813 is arranged inside the fixed pipe 82 to limit the vertical pipe 84. When the grab assembly 6 presses down the movable ring 85, the movable ring 85 compresses the third tension spring 820, so that the other annular groove 814 moves to a position flush with the limiting bead 813. Then, when the vertical pipe 84 enters the fixed pipe 82, the annular convex strip 86 on the outer wall of the vertical pipe 84 will position the vertical pipe 84. The limiting bead 813 in the hole 812 is pushed into the annular groove 814 to ensure that the vertical pipe 84 can smoothly enter the fixed pipe 82. The upper part of the limiting bead 813 will be restricted by the anti-drop ring 819 to prevent the limiting bead 813 from falling off. After the vertical pipe 84 is fully inserted, the movable ring 85 is released. The rebound of the third tension spring 820 will bounce the movable ring 85 again, push the limiting bead 813 into the accommodating groove 87, and cover the limiting bead 813, thereby completing the locking of the vertical pipe 84 and the fixed pipe 82.

[0056] Before releasing the vertical pipe 84, the movable ring 85 is pressed down again to release the limiting bead 813. At this time, the second tension spring 818 and the first tension spring 811 can rebound the vertical pipe 84 to make the vertical pipe 84 detach from the fixed pipe 82. Then the movable ring 85 is released, and the third tension spring 820 bounces the movable ring 85 to cover the limiting bead 813 again to prevent the vertical pipe 84 from entering the fixed pipe 82.

When the water is released, the water will completely stay inside the water meter model 41. When the water in the water meter model 41 needs to be released later, the support rod 21 is driven by the electric telescopic rod 7 to insert the docking pipe 23 into the inside of the one-way valve 44, thereby pushing open the blockage in the one-way valve 44 and allowing the water to flow out of the docking pipe 23.

[0067] Step 4: Start the freezing platform 3 to freeze the water in the water absorption component 8. The purpose of freezing the parts is achieved by freezing the water, so that the parts are fixed in the water meter model 41. The water flows into the water delivery pipe 47 through the fixed pipe 82. Since the water delivery pipe 47 is in direct contact with the water meter model 41, and the freezing platform 3 will reduce the temperature of the water meter model 41, the water remaining in the water delivery pipe 47 and the vertical pipe 84 will be frozen, and the water on the surface of the parts will also be gradually frozen, and the purpose of fixing the parts is finally achieved. The water in the fixed pipe 82 freezes from bottom to top in sequence. After the water on the surface of the model freezes, the water delivery is stopped to avoid the freezing of the water in the water discharge pipe 62, and the grabbing component 6 is moved away from the top of the water meter model 41.

[0068] Step 5: After the fixation is completed, the grabbing assembly 6 releases the parts, grabs new parts to the top of the support plate 46 for positioning and assembly, and repeats the first, second, third and fourth steps;

[0069] Step 6: After the assembly is completed, close the freezing platform 3 and let the ice cubes thaw naturally. The thawed water flows out from the docking pipe 23. After removing the assembled movement, use the mechanical claw 61 to press down the movable ring 85 again. The rebound of the first tension spring 811 and the second tension spring 818 can pop the vertical pipe 84 out of the fixed pipe 82.
