TECHNICAL FIELD

[0002] The existing intelligent water meter metering is realized by using a magnetic steel in cooperation with a sensor, wherein the magnetic steel is installed on the side wall of the water meter cover in order to shorten the distance between the magnetic steel and the sensor and make the signal acquisition more stable and reliable; therefore, when assembling the water meter cover of the intelligent water meter, the user needs to first use an installation equipment to fix and install the magnetic steel on the inner wall of the water meter cover, and then the worker covers the water meter with the water meter cover and places the water meter with the covered water meter cover on a conveying belt, so that the conveying belt conveys the water meter with the covered water meter cover to the water meter cover assembly machine, and the water meter cover assembly machine can tighten the water meter cover on the water meter.

[0003] The existing water meter cover assembly machine can be divided into a single-station water meter cover assembly machine and a multi-station water meter cover assembly machine according to the number of stations; no matter the single-station water meter cover assembly machine or the multi-station water meter cover assembly machine, the number of stations for assembly is fixed; however, the production demand of the water meter is affected by seasonal changes, i.e. in seasons with large temperature changes, the water meter may have more faults (such as freezing damage), resulting in the need for a large number of water meter replacements in some seasons, and in this season, the production demand of the water meter needs to be increased.

[0004] The fixed number of tightening stations will limit the number of water meters assembled per day, which will result in the inability to meet orders in time when the market demand for water meters increases; to this end, if the number of water meter cover assembly machines is increased, the production efficiency of the water meter can be improved when the demand for water meters is high, and orders can be met in time, but when the demand for water meters is low in seasons, too many tightening stations will be idle in the low demand period; and the equipment in the idle state for a long time requires more time and cost for maintenance and management, including equipment maintenance, labor cost and site rental, etc., which will affect the profitability of the enterprise.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 8 As shown, the device for assembling a smart water meter with a magnetic steel cover according to the present invention includes:

[0035] Mounting plate 2 is located within the feeding channel 11. Mounting plate 2 is connected to the upper wall of the feeding channel 11 via a hydraulic push rod 21. An mounting cavity 22 is formed inside the mounting plate 2. A connecting gear 221 and a transmission gear 222 are rotatably connected within the mounting cavity 22. A drive motor 223 is fixedly mounted on the upper end of the mounting plate 2. The drive motor 223 drives the connecting gear 221 to rotate. A transmission belt 224 is fitted onto the surfaces of both the connecting gear 221 and the transmission gear 222. A meshing groove 225 is formed on the inner wall of the transmission belt 224. The transmission belt 224 meshes with the transmission gear 222 and the connecting gear 221 through the meshing groove 225.

[0036] Mounting cylinder 23; the mounting cylinder 23 is rotatably connected to the lower end of mounting plate 2; the mounting cylinder 23 is fixedly connected to transmission gear 222; an assembly rod 231 is provided below the mounting cylinder 23; one end of the assembly rod 231 is threadedly connected to the mounting cylinder 23, and the other end is fixedly connected to the assembly disc 232; a strip groove 233 is provided at the lower end of the assembly disc 232; a clamping block 234 is slidably connected in the strip groove 233; an electric push rod 235 is fixedly connected in the strip groove 233; one end of the electric push rod 235 is fixedly connected to the clamping block 234; the other end penetrates the outer surface of the assembly disc 232.

[0037] A limiting unit is installed in the feed channel 11; the limiting unit is used to adjust the position of the water meter conveyed at the upper end of the conveyor belt 111.

[0038] In one embodiment of the present invention, the limiting unit includes a limiting plate 24; the limiting plate 24 is made of carbon steel; the cross-sectional shape of the limiting plate 24 is S-shaped; there are two limiting plates 24; the two limiting plates 24 are distributed opposite each other; a guide rod 13 and a lead rod 14 are rotatably connected to both ends of the feeding channel 11; one end of the limiting plate 24 is helically connected to the lead rod 14, and the other end is slidably connected to the guide rod 13; the threads at both ends of the lead rod 14 are arranged in opposite directions.

[0039] In one embodiment of the present invention, the limiting plate 24 has a groove 241 at one end near the lead screw 14; a slider 242 is slidably connected in the groove 241; the slider 242 is fixedly connected to the bottom of the groove 241 by a connecting spring 243; an electromagnetic plate 244 is embedded in the bottom of the groove 241; a blocking rod 245 is provided below the lead screw 14; the blocking rod 245 is slidably connected to the slider 242; and the blocking rod 245 is in sliding contact with the inner wall of the feed channel 11.

[0040] In one embodiment of the present invention, the side wall of the limiting plate 24 is provided with a positioning groove 25; a pneumatic push rod 251 is provided in the positioning groove 25; the pneumatic push rod 251 is fixedly installed on the side of the two limiting plates 24 that are far apart from each other by means of a U-shaped plate 252; a positioning plate 253 is fixedly connected to the end of the pneumatic push rod 251 that is far away from the U-shaped plate 252.

[0041] In one embodiment of the present invention, a distance sensor is mounted on the surface of the limiting plate 24; the distance sensor includes a first distance sensor 15 and a second distance sensor 16; the first distance sensor 15 is embedded in the end of the limiting plate 24 near the lead screw 14; the second distance sensor 16 is embedded in the end of the positioning plate 253 away from the pneumatic push rod 251;

[0042] During operation, a fixed number of tightening stations limits the number of water meters that can be assembled each day. This results in an inability to meet orders in a timely manner when the market demand for water meters increases. Increasing the number of water meter assembly machines can improve production efficiency and meet orders in a timely manner when the demand for water meters is high. However, during seasons when the demand for water meters is low, too many tightening stations will be idle. Long-term idleness of equipment requires more time and costs for maintenance and management, including equipment maintenance, labor costs, and site rental, which in turn affects the company's profitability.

[0043] In this invention, the mounting cylinder 23 and the assembly rod 231 are movably connected, allowing the assembly rod 231 to be movably connected to the mounting cylinder 23. This increases the number of assembly rods 231 when water meter market demand increases, thereby increasing the number of water meters installed each time, improving the assembly efficiency of the water meter cover, and ultimately increasing water meter production efficiency. Conversely, during seasons with low water meter demand, the assembly rods 231 can be removed and stored, reducing the time and maintenance costs associated with excessive tightening stations, thus improving the company's profitability. Therefore, the practical application effect of this invention is effectively enhanced.

[0044] In its initial state, the limiting plate 24 is made of carbon steel and is S-shaped, meaning that one end of the two limiting plates 24 is farther apart than the other. The carbon steel limiting plate 24 has good rigidity, ensuring that when the pneumatic push rod 251 of the two limiting plates 24 clamps the water meter to be assembled via the positioning plate 253, the water meter obstructs the positioning plate 253. This causes the positioning plate 253 to transmit the obstructing force to the pneumatic push rod 251. Under the action of this obstructing force, the pneumatic push rod 251 exerts a pulling force on the limiting plate 24 through the Z-shaped plate 252. Since forces are reciprocal, the clamping force generated by the positioning plate 253 on the water meter is equal to the pulling force transmitted from the positioning plate 253 to the limiting plate 24 via the pneumatic push rod 251. To mitigate the force, the positioning plate 253 is made of carbon steel, ensuring its rigid structure can withstand the pulling force of the pneumatic push rod 251. This not only secures the water meter to be assembled but also prevents the limiting plate 24 from deforming, thus improving its practicality. The Z-shaped plate 252 is designed to facilitate the disassembly and installation of the pneumatic push rod 251. During seasons with low water meter demand, the pneumatic push rod 251 can be removed for maintenance and storage, preventing wear caused by environmental factors (such as dust and moisture) or mechanical operation. Disassembly and storage can avoid these effects and extend the service life of the pneumatic push rod 251 and the positioning plate 253.

[0045] A handle is fixed to one end of the lead screw 14 near the operation panel 12. The user rotates the handle to rotate the lead screw 14, causing it to drive the limiting plates 24 closer together, so that the distance between the two limiting plates 24 is the diameter of the water meter cover to be assembled. The user then places the water meter cover over the water meter and positions the covered water meter at the center of the conveyor belt 111, positioning the water meter to be assembled at the end of the conveyor belt 111 furthest from the two limiting plates 24. The conveyor belt 111 is then controlled to move the water meter to be assembled into the feed channel 11 until it reaches between the two limiting plates 24. As the conveyor belt 111 continues to move the water meter closer to the limiting plates 24, the water meter to be assembled... The pipe joints at both ends of the water meter contact the limiting plates 24 on both sides in sequence. As the conveyor belt 111 continues to transport the water meter to be assembled, the water meter to be assembled can continuously move towards the center of the two limiting plates 24 under the obstruction of the limiting plates 24. This ensures that the water meter to be assembled is vertically positioned between the two limiting plates 24 under the alignment of the two limiting plates 24. This ensures that when the conveyor belt 111 transports the water meter to be assembled into the feeding channel 11, the water meter to be assembled slides in contact with the two limiting plates 24, and the water meter to be assembled entering the feeding channel 11 is positioned directly below the assembly rod 231, so that the subsequent assembly rod 231 can clamp and tighten the water meter cover at the upper end of the water meter to be assembled, facilitating the assembly of the water meter. This effectively improves the practicality of the invention.

[0046] The conveyor belt 111 transports water meters to be assembled. When the water meters are between the two limit plates 24, they pass between the two distance sensors 15. The distance sensors 15 detect the number of water meters that have entered the feeding channel 11 and are located between the two limit plates 24 by sensing the distance between themselves and the water meters. The number of water meters to be assembled each time is set to the number of assembly rods 231 in the feeding channel 11 via the operation panel 12. When the number of water meters to be assembled in the feeding channel 11 reaches the set value, the operation panel 12 directly controls the operation of the electromagnetic plate 244. Since the slider 242 is made of iron metal, the electromagnetic plate 244 magnetically attracts the slider 242. The force applied causes the slider 242 to compress the connecting spring 243 and descend along the slide groove 241, causing the slider 242 to drive the blocking rod 245, which is slidably connected to it, to descend. This allows the descending blocking rod 245 to block the water meter to be assembled that is being conveyed by the conveyor belt 111 to the inlet of the feeding channel 11. This continues until the water meter to be assembled in the feeding channel 11 is tightened and assembled with the water meter cover. Then, the electromagnetic plate 244 is de-energized, causing the slider 242 to move away from the conveyor belt 111 along the slide groove 241 under the restoring force of the connecting spring 243. This causes the slider 242 to drive the blocking rod 245 to rise, so that the blocking rod 245 no longer blocks the water meter to be assembled, allowing the water meter to be assembled to enter the feeding channel 11 from below the blocking rod 245.

[0047] When the water meter to be assembled moves to the position below the assembly rod 231, which is away from the lead screw 14, the water meter will first pass between two opposing positioning plates 253 that are close to the assembly rod 231 and relatively close to the lead screw 14. This causes the second distance sensor 16 on the two opposing positioning plates 253 to detect the water meter to be assembled. That is, when the pipe joint of the water meter to be assembled is first located between the two opposing positioning plates 253, the second distance sensor 16 on the two opposing positioning plates 253 senses a change in distance. At this time, the distance sensor transmits an electrical signal to the pneumatic push rod 251, causing the pneumatic push rods 251 on both sides of the water meter to push the positioning plates 253 closer to the pipe joint of the water meter to be assembled. At this time, the water meter to be assembled rotates under the push of the positioning plates 253, making the axes of the two pipe joints of the water meter to be assembled parallel to the positioning plates 253. At the same time, the pneumatic push rod 251 retracts. The conveyor belt 111 continues to transport the water meter to be assembled. When both pipe joints of the water meter to be assembled are located between the two sets of positioning plates 253 facing each other near the assembly rod 231, the sensing distance of the second distance sensor 16 of the two sets of positioning plates 253 changes. When the sensing distances of the two sets of second distance sensors 16 are the same, the water meter to be assembled is located between the two sets of positioning plates 253 facing each other near the assembly rod 231. That is, the water meter to be assembled and the assembly rod 231 are in a vertically facing state. At this time, the operation panel 12 controls the pneumatic push rod 251 to move, so that the pneumatic push rod 251 pushes the positioning plate 253 to clamp the pipe joints at both ends of the water meter to be assembled, so that the limiting plate 24 can clamp and limit the water meter to be assembled through the pipe joints at both ends of the water meter to be assembled. Similarly, the water meters to be assembled located in the feeding channel 11 are clamped and positioned directly below the assembly rod 231 in sequence.

[0048] Then, control the hydraulic push rod 21 to move, so that the hydraulic push rod 21 can push the mounting plate 2 down, so that the mounting plate 2 can drive the assembly rod 231 down, so that the assembly rod 231 can continuously approach the water meter to be assembled below; until the assembly plate 232 fixed to the lower end of the assembly rod 231 contacts the water meter cover of the water meter to be assembled. At this time, control the electric push rod 235 to move, so that the electric push rod 235 can push the clamping block 234 in the strip groove 233 to move along the strip groove 233 towards the center of the assembly plate 232; since the lower end of the assembly plate 232 is provided with four clamping blocks 234 4. This allows the four clamping blocks 234 to clamp the water meter cover; then, the drive motor 223 is controlled to run, enabling the drive motor 223 to drive the connecting gear 221 to rotate. The rotating connecting gear 221 then drives the transmission belt 224 to rotate within the mounting cavity 22 via the meshing groove 225 of the transmission belt 224. During the rotation of the transmission belt 224, the transmission belt 224 drives the transmission gear 222, which meshes with it, to rotate. Since the transmission gear 222 is fixedly connected to the mounting cylinder 23, and the mounting rod 231 is threadedly connected to the mounting cylinder 23, the transmission gear... When the mounting cylinder 23 rotates, the mounting cylinder 23 will drive the lower assembly rod 231 to rotate synchronously. During this rotation, the assembly rod 231 will drive the lower clamping block 234 to rotate, causing the clamping block 234 to rotate and hold the water meter cover. The water meter to be assembled is held by the positioning plates 253 on both sides, so the water meter will not rotate. The water meter cover, driven by the clamping block 234, will rotate relative to the water meter, continuously tightening the water meter cover onto the upper part of the water meter. At this point, the assembly of the water meter and water meter cover is complete. Then, the control circuit... The electric push rod 235 and the pneumatic push rod 251 retract, causing the electric push rod 235 to pull the clamping block 234 away from the water meter cover, so that the clamping block 234 no longer clamps the water meter cover. Meanwhile, the pneumatic push rod 251 pulls the positioning plate 253 away from the water meter's pipe joint, so that the positioning plate 253 no longer positions the water meter through the water meter's pipe joint. Then, the hydraulic push rod 21 is controlled to rise, so that the hydraulic push rod 21 pulls the clamping block 234 away from the water meter cover through the assembly rod 231. Finally, the conveyor belt 111 is controlled to transport the assembled water meter through the feeding channel 11 and discharge it from the end near the bare rod 13.

[0049] When it is necessary to install or remove the assembly rod 231, the user pulls the two sliding doors 122 to move them away from each other, so that the two sliding doors 122 no longer block the operation window 121, allowing the operation window 121 to be opened. This facilitates the user to install and remove the assembly rod 231 in the feed channel 11 through the operation window 121. Specifically, when removing the assembly rod 231, the user uses tools such as clamps to hold and fix the assembly rod 231, and then controls the drive motor 223 to rotate in the opposite direction. This allows the drive motor 223 to drive the transmission gear 222 to rotate through the connecting gear 221 and the transmission belt 224, causing the transmission gear 222 to drive the mounting cylinder 23 to rotate. Because the assembly rod 231 is held and fixed, there is a relative rotation between the assembly rod 231 and the mounting cylinder 23, causing the assembly rod 231 to rotate in the opposite direction and exit from the mounting cylinder. The assembly rod 231 is removed by extending outward from the inside of the cylinder 23. Similarly, when the assembly rod 231 needs to be installed, the drive motor 223 is controlled to drive the mounting cylinder 23 to rotate in the forward direction, so that the clamped assembly rod 231 and the mounting cylinder 23 rotate relative to each other, and the assembly rod 231 can be tightened into the mounting cylinder 23. Thus, the number of assembly rods 231 can be changed according to market demand to increase or decrease the number of water meters assembled per day. That is, when the water meter market demand is high, the number of assembly rods 231 is increased, thereby increasing the number of water meters installed each time, improving the assembly efficiency of the water meter cover, and thus improving the production efficiency of water meters. In the quarter when the water meter demand is low, the assembly rods 231 can be removed and stored, which can reduce the time cost and maintenance and management cost caused by too many tightening stations, thereby improving the profitability of enterprises. Thus, the practical application effect of the present invention is effectively improved.

[0050] In one embodiment of the present invention, a hinge groove 26 is provided on the upper end face of the positioning plate 253; a hinge plate 261 is rotatably connected in the hinge groove 26; the hinge plate 261 is rotatably connected in the hinge groove 26 by a torsion spring.

[0051] In one embodiment of the present invention, a groove 27 is provided at the lower end of the positioning plate 253; a blocking block 271 is slidably connected in the groove 27; a magnet 272 is embedded at one end of the blocking block 271 near the bottom of the groove 27; and an electromagnetic plate 273 is embedded at the bottom of the groove 27.

[0052] In one embodiment of the present invention, an elastic block 28 is fixedly connected to one end of the positioning plate 253 away from the pneumatic push rod 251; the elastic block 28 is made of fluororubber material; a shell 29 is sleeved on the surface of the limiting plate 24; the shell 29 is made of PTFE material;

[0053] During operation, due to the different heights of the pipe joints of different models of water meters to be assembled, in order to ensure that the positioning plate 253 can effectively limit and clamp the pipe joints of different heights, this invention sets up a hinge plate 261 and a blocking block 271; and in the initial state, the hinge plate 261 is in an upward tilted state. If the pipe joint of the water meter to be assembled is at a higher position, when the pneumatic push rod 251 pushes the positioning plate 253 to contact the pipe joint of the water meter to be assembled, the hinge plate 261 will contact the pipe joint of the water meter to be assembled first, so that the circular outer surface of the pipe joint of the water meter to be assembled blocks the hinge plate 261, thus... The hinge plate 261 can overcome the torsion of the torsion spring and rotate towards the positioning plate 253 under the obstruction of the pipe joint of the water meter to be assembled, until the hinge plate 261 blocks the groove wall of the hinge groove 26, so that the groove wall of the hinge groove 26 supports the hinge plate 261, thereby enabling the positioning plate 253 to effectively clamp and limit the pipe joint of the water meter to be assembled at a higher position angle through the hinge plate 261; if the pipe joint of the water meter to be assembled is at a lower position, as the pneumatic push rod 251 pushes the positioning plate 253 out of the positioning groove 25, the positioning plate 253 drives the blocking block 2 in the groove 27. 71 extends beyond the positioning groove 25 and is positioned between the two limiting plates 24; initially, the blocking block 271 is attracted to the bottom of the groove 27 by the magnet 272, causing the blocking block 271 to penetrate deep into the groove 27; at this time, the control electromagnetic plate 273 is energized, causing the electromagnetic plate 273 to generate the same stimulation as the magnet 272, causing the magnet 272 to move away from the electromagnetic plate 273 under the magnetic repulsion force of the electromagnetic plate 273; since the electromagnetic plate 273 is embedded in the bottom of the groove 27, and the magnet 272 is embedded at the end of the blocking block 271 near the bottom of the groove 27, the magnet 272... 72 can push the blocking block 271 to extend away from the bottom of the groove 27 under the action of magnetic repulsion, so that the blocking block 271 extending out of the groove 27 can approach the pipe joint of the water meter to be assembled under the action of the positioning plate 253, so that the blocking block 271 can clamp and limit the pipe joint at a lower position, so that the present invention can effectively limit and clamp the pipe joint at different height positions of different models of water meters to be assembled, so as to facilitate the assembly of water meter covers for different models of water meters to be assembled, thereby effectively improving the practical application range of the present invention; thus improving the practicality of the present invention.

[0054] In the initial state, the positioning plate 253 is positioned within the positioning groove 25 by the pneumatic push rod 251 because when the user slides the water meter to be assembled between the two limiting plates 24, the water meter may be slightly tilted due to human error. At this time, the pipe joint near the guide rod 13 tilts towards one of the limiting plates 24 and slides in contact with the limiting plate 24. If the positioning plate 253 extends out of the positioning groove 25, the pipe joint of the water meter to be assembled, which is in contact with the limiting plate 24, will move to the positioning groove 25 under the conveyor belt 111. This causes the positioning plate 253 extending out of the positioning groove 25 to collide with the pipe joint of the water meter to be assembled. The pipe joint of the water meter to be assembled is blocked by the positioning plate 253, affecting the normal movement of the pipe joint conveyed by the conveyor belt 111. Therefore, by setting the positioning plate 253 within the positioning groove 25, it is possible to ensure that the water meter to be assembled is accurately moved to the bottom of the assembly rod 231 for effective assembly under the conveyor belt 111, thus ensuring the normal and stable operation of this invention.

[0055] The reason for fixing an elastic block 28 to the end of the positioning plate 253 away from the pneumatic push rod 251 is that the pipe joint of the water meter to be assembled is cylindrical. When the positioning plate 253 approaches the pipe joint of the water meter to be assembled, the positioning plate 253 will drive the elastic block 28 to contact the pipe joint of the water meter to be assembled first. When the elastic block 28 connected to the positioning plate 253 of the two limiting plates 24 clamps the pipe joint of the water meter to be assembled, the pipe joint of the water meter to be assembled generates a blocking force on the elastic block 28, causing the elastic block 28 to deform under the action of the blocking force. This allows the elastic block 28 to deform, increasing the contact area between the elastic block 28 and the pipe joint of the water meter to be assembled, thereby improving the clamping effect of the elastic block 28 on the pipe joint of the water meter to be assembled. This prevents the water meter from sliding due to the clamping force, which would cause the pipe joint to detach from the two positioning plates 253. Such slippage would not only affect the clamping effect of the positioning plates 253 on the pipe joint, but also prevent the water meter from being accurately positioned with the assembly rod 231, leading to… The assembly rod 231 cannot clamp and rotate the water meter cover of the water meter to be assembled via the lower clamping block 234. Therefore, the elastic block 28 improves the clamping stability of the positioning plate 253 on the water meter pipe joint to be assembled. The elastic block 28 is made of fluororubber, which not only has elasticity but also good high-temperature resistance and wear resistance. This allows the fluororubber elastic block 28 to maintain its physical properties and chemical stability at high temperatures, making it less prone to aging, deterioration, and cracking. Moreover, since the outer surface of the water meter pipe joint to be assembled is usually threaded to facilitate the connection between the water meter and the water pipe, the elastic block 28 will contact the threads of the outer wall of the water meter pipe joint when clamping it. The fluororubber elastic block 28 has good wear resistance, which effectively reduces the wear caused by the threads of the outer wall of the water meter pipe joint during clamping, thereby improving the service life of the elastic block 28 and effectively enhancing the practical application effect of the present invention.By fixing a PTFE outer shell 29 to the surface of the limiting plate 24, the outer shell 29 can protect the limiting plate 24 from scratches or wear caused by sliding friction between the water meter pipe fitting to be assembled and the limiting plate 24, thus improving the service life of the limiting plate 24. Furthermore, the PTFE outer shell 29 has a smooth surface and a low coefficient of friction, which reduces the friction between the water meter pipe fitting and the outer shell 29 when they come into contact, reducing wear on the outer shell 29 and preventing further damage. The reduced friction on the conveyor belt 111 improves its conveying efficiency for water meters. Furthermore, the sliding contact between the limiting plate 24 and the conveyor belt 111 via the outer casing 29 reduces wear on the conveyor belt 111, extending its service life. Since the limiting plate 24 is made of carbon steel, the outer casing 29 protects it from corrosion by external air, further improving its service life and enhancing the practicality of the invention.
