[0001] The invention relates to the technical field of water meter assembly, in particular to a device for assembling an intelligent water meter with a magnetic steel water meter cover. Background Art

[0002] The existing intelligent water meter measurement is realized by using a magnet and a sensor. In order to shorten the distance between the magnet and the sensor and make the signal acquisition more stable and reliable, the magnet is installed on the side wall of the water meter cover. Therefore, when assembling the water meter cover of the intelligent water meter, the user needs to first use the installation equipment to fix the magnet on the inner wall of the water meter cover, and then the worker covers the water meter cover on the water meter, and places the water meter covered with the water meter cover on the conveyor belt, so that the conveyor belt transports the water meter covered with the water meter cover to the water meter cover assembly machine, so that the water meter cover assembly machine can tighten the water meter cover on the water meter. Existing water meter cover assembly machines can be divided into single-station water meter cover assembly machines and multi-station water meter cover assembly machines according to the number of workstations. Whether it is a single-station water meter cover assembly machine or a multi-station water meter cover assembly machine, the number of assembly workstations is fixed; however, the production demand of water meters is affected by seasonal changes, that is, in seasons with large temperature changes, water meters may have more faults (such as freezing damage), resulting in a large number of water meters needing to be replaced in certain seasons, and in this season, the production demand of water meters needs to be increased; A fixed number of tightening stations will limit the number of water meters assembled every day, which will result in the inability to meet orders in time when the market demand for water meters increases. In this regard, if the number of water meter cover assembly machines is increased, although the production efficiency of water meters can be improved when the demand for water meters is high, and orders can be met in time, in the quarter when the demand for water meters is low, too many tightening stations will be idle when the demand is low; if the equipment is idle for a long time, it will take more time and cost to maintain and manage, including equipment maintenance, labor costs and site rental, which will affect the profitability of the enterprise; In view of this, in order to overcome the above technical problems, the present invention proposes a device for assembling a smart water meter with a magnetic steel water meter cover, which solves the above technical problems.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] As an embodiment of the present invention, the limiting unit includes a limiting plate 24; the limiting plate 24 is made of carbon steel material; the cross-sectional shape of the limiting plate 24 is set to be S-shaped; the number of the limiting plates 24 is set to two; the two limiting plates 24 are arranged opposite to each other; the two ends of the feed channel 11 are respectively rotatably connected with a light rod 13 and a screw rod 14; one end of the limiting plate 24 is spirally connected to the screw rod 14, and the other end is slidingly connected to the light rod 13; the threads at both ends of the screw rod 14 are oppositely arranged.

[0019] As an embodiment of the present invention, a slide groove 241 is provided at one end of the limit plate 24 close to the screw rod 14; a slider 242 is slidably connected in the slide groove 241; the slider 242 is fixedly connected to the bottom of the slide groove 241 by a connecting spring 243; an electromagnetic plate 244 is inlaid at the bottom of the slide groove 241; a blocking rod 245 is arranged under the screw rod 14; the blocking rod 245 is slidably connected to the slider 242; the blocking rod 245 is in sliding contact with the inner wall of the feed channel 11.

[0020] As an embodiment of the present invention, a positioning groove 25 is provided on the side wall of the limit plate 24; a pneumatic push rod 251 is arranged in the positioning groove 25; the pneumatic push rod 251 is fixedly installed on the side of the two limit plates 24 away from each other through an I-shaped plate 252; the end of the pneumatic push rod 251 away from the I-shaped plate 252 is fixedly connected to a positioning plate 253.

[0021] As an embodiment of the present invention, a distance sensor is installed on the surface of the limit plate 24; the distance sensor includes a No. 1 distance sensor 15 and a No. 2 distance sensor 16; the No. 1 distance sensor 15 is embedded in one end of the limit plate 24 close to the screw rod 14; the No. 2 distance sensor 16 is embedded in one end of the positioning plate 253 away from the pneumatic push rod 251; During operation, a fixed number of tightening stations will limit the number of water meters assembled every day, which will result in the inability to meet orders in a timely manner when the market demand for water meters increases. In this regard, if the number of water meter cover assembly machines is increased, although the production efficiency of water meters can be improved when the demand for water meters is high, and orders can be met in a timely manner, in the quarter when the demand for water meters is low, too many tightening stations will be idle when the demand is low; and if the equipment is idle for a long time, it will take more time and cost to maintain and manage, including equipment maintenance, labor costs and site rental, which will affect the profitability of the enterprise; In this regard, the present invention arranges the installation cylinder 23 and the assembly rod 231 so that the assembly rod 231 is movably connected to the installation cylinder 23. Therefore, when the market demand for water meters increases, the number of assembly rods 231 is increased, thereby increasing the number of water meters installed each time, improving the assembly efficiency of water meter covers, and thus improving the production efficiency of water meters. In seasons with low demand for water meters, the assembly rods 231 are removed and stored, which can reduce the time cost and maintenance and management cost increased by too many tightening stations, thereby improving the profitability of the enterprise; so that the practical application effect of the present invention is effectively improved; In the initial state, the limit plate 24 is made of carbon steel material, and the limit plate 24 is set to S shape, so that one end of the two limit plates 24 is far away, and the other end is close. The limit plates 24 made of carbon steel have good rigidity, so that when the pneumatic push rods 251 of the two limit plates 24 clamp the water meter to be assembled through the positioning plate 253, the water meter blocks the positioning plate 253, so that the positioning plate 253 transmits the blocking force to the pneumatic push rod 251, so that the pneumatic push rod 251 generates a pulling force on the limit plate 24 through the "X"-shaped plate 252 under the action of the blocking force. Because the force is mutual, 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 limit plate 24 via the pneumatic push rod 251 force, so the positioning plate 253 is made of carbon steel material, so that the rigid structure of the positioning plate 253 itself can resist the pulling force of the pneumatic push rod 251, while ensuring that the positioning plate 253 clamps the water meter to be assembled, it can also prevent the limit plate 24 from being deformed, thereby improving the practicality of the limit plate 24; the setting of the cross-shaped plate 252 is to facilitate the disassembly and installation of the pneumatic push rod 251. In the season when the demand for water meters is low, the pneumatic push rod 251 is disassembled for maintenance and storage by operators, thereby preventing wear caused by environmental factors (such as dust, moisture) or mechanical operation. Storing it after disassembly can avoid these effects and extend the service life of the pneumatic push rod 251 and the positioning plate 253; A handle is fixedly connected to one end of the screw rod 14 close to the operation panel 12. The user drives the screw rod 14 to rotate by turning the handle, so that the screw rod 14 can drive the limit plates 24 to approach each other, so that the distance between the two limit plates 24 is the diameter of the water meter cover to be assembled; then the user covers the water meter cover on the water meter, and places the water meter covered with the water meter cover on the central part of the conveyor belt 111, so that the water meter to be assembled is located at the end of the conveyor belt 111 that is farther away from the two limit plates 24; the conveyor belt 111 is controlled to transport the water meter to be assembled to move into the feed channel 11, so that until the conveyor belt 111 transports the water meter to be assembled between the two limit plates 24, as the conveyor belt 111 continues to transport the water meter to be assembled close to the limit plates 24, the water meter to be assembled The pipe joints at both ends of the water meter contact with the limit plates 24 on both sides in sequence, and as the conveyor belt 111 continues to transport the water meter to be assembled, the water meter to be assembled can be continuously moved toward the center of the two limit plates 24 under the obstruction of the limit plates 24, so that the water meter to be assembled is located between the two limit plates 24 vertically below the two limit plates 24, so as to ensure that when the conveyor belt 111 transports the water meter to be assembled into the feed channel 11, the water meter to be assembled is in sliding contact with the two limit plates 24, and the water meter to be assembled entering the feed channel 11 can be located directly under 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, so as to facilitate the assembly of the water meter; so that the practicality of the present invention is effectively improved; When the conveyor belt 111 transports the water meter to be assembled and is located between the two limit plates 24, the water meter to be assembled will pass between the two No. 1 distance sensors 15, so that the No. 1 distance sensor 15 senses the distance between itself and the water meter to be assembled, and then detects the number of water meters to be assembled that pass through the No. 1 distance sensor 15 and enter the feed channel 11 and are located between the two limit plates 24; the number of water meters to be assembled each time is set to the number of assembly rods 231 in the feed channel 11 through the operation panel 12; when the number of water meters to be assembled entering the feed channel 11 reaches the set value, the operation panel 12 directly controls the operation of the electromagnetic sheet 244; since the slider 242 is made of iron metal material, the electromagnetic sheet 244 generates magnetic attraction to the slider 242. The slider 242 is pressed by the connecting spring 243 and descends along the slide groove 241, so that the slider 242 drives the blocking rod 245 slidably connected thereto to descend, so that the descending blocking rod 245 can block the water meter to be assembled that is transported by the conveyor belt 111 to the mouth of the feeding channel 11; until the water meter to be assembled in the feeding channel 11 and the water meter cover are tightened and assembled, and then the electromagnetic sheet 244 is controlled to be powered off, so that the slider 242 moves along the slide groove 241 away from the conveyor belt 111 under the push of the restoring force of the connecting spring 243, so that the slider 242 drives the blocking rod 245 to rise, so that the blocking rod 245 no longer blocks the water meter to be assembled, so that the water meter to be assembled can enter the feeding channel 11 from below the blocking rod 245; When the water meter to be assembled moves to the bottom of the assembly rod 231 away from the screw rod 14, the water meter to be assembled will first pass between the two opposite positioning plates 253 close to the assembly rod 231 and closer to the screw rod 14, so that the No. 2 distance sensor 16 on the two opposite positioning plates 253 detects 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 opposite positioning plates 253, the No. 2 distance sensor 16 on the two opposite positioning plates 253 senses a change in distance. At this time, the distance sensor transmits an electrical signal to the pneumatic push rod 251, so that the pneumatic push rods 251 on both sides of the water meter to be assembled push the positioning plates 253 close to the pipe joints 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, so that the axis of the two pipe joints of the water meter to be assembled is parallel to the positioning plates 253. At the same time, the pneumatic push rod 251 contracts. The conveyor belt 111 continues to convey the water meter to be assembled, so that the two pipe joints of the water meter to be assembled are located between the two groups of positioning plates 253 facing each other close to the assembly rod 231. At this time, the sensing distance of the No. 2 distance sensor 16 of the two groups of positioning plates 253 changes, and when the sensing distances of the two groups of No. 2 distance sensors 16 are the same, the water meter to be assembled is located between the two groups of positioning plates 253 close to 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 operate, 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 limit 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 meter to be assembled in the feed channel 11 is clamped and positioned directly below the assembly rod 231 in sequence; Then, the hydraulic push rod 21 is controlled to operate so that the hydraulic push rod 21 can push the mounting plate 2 down, so that the mounting plate 2 drives the assembly rod 231 to move down, so that the assembly rod 231 can continuously approach the water meter to be assembled below; until the assembly plate 232 fixedly connected to the lower end of the assembly rod 231 contacts the water meter cover to be assembled, at this time, the electric push rod 235 is controlled to operate 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 to the center of the assembly plate 232; since the lower end of the assembly plate 232 is provided with four clamping blocks 23 4, so that the four clamping blocks 234 can clamp the water meter cover; then control the driving motor 223 to run, so that the driving motor 223 can drive the connecting gear 221 to rotate, so that the rotating connecting gear 221 can drive the transmission belt 224 to rotate around in the installation cavity 22 through the meshing groove 225 of the transmission belt 224, so that during the rotation of the transmission belt 224, the transmission belt 224 can drive the transmission gear 222 meshed with it to rotate; since the transmission gear 222 is fixedly connected to the installation cylinder 23, and the assembly rod 231 is threadedly connected to the installation cylinder 23, When 222 drives the installation cylinder 23 to rotate, the installation cylinder 23 will drive the assembly rod 231 at the lower end to rotate synchronously, so that the assembly rod 231 can drive the clamping block 234 at the lower end to rotate during the rotation process, so that the clamping block 234 drives the clamped water meter cover to rotate, and the water meter to be assembled is clamped by the positioning plates 253 on both sides, so the water meter to be assembled will not rotate, so that the water meter cover is driven by the clamping block 234 and rotates relative to the water meter to be assembled, so that the water meter cover is continuously tightened on the upper end of the water meter to be assembled, and the assembly of the water meter and the water meter cover is completed, and then the control circuit is turned on. The electric push rod 235 and the pneumatic push rod 251 are retracted, so that the electric push rod 235 pulls the clamping block 234 away from the water meter cover, so that the clamping block 234 no longer clamps the water meter cover, and the pneumatic push rod 251 pulls the positioning plate 253 away from the pipe joint of the water meter, so that the positioning plate 253 no longer positions the water meter through the pipe joint of the water meter, and 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, and finally the conveyor belt 111 is controlled to transport the assembled water meter to be discharged through the end of the feed channel 11 close to the polished rod 13; When the assembly rod 231 needs to be installed or removed, the user pulls the two sliding doors 122 to move away from each other, so that the two sliding doors 122 no longer block the operation window 121, so that the operation window 121 is opened, so that the user can install and remove the assembly rod 231 in the feed channel 11 through the operation window 121. That is, when removing the assembly rod 231, the assembly rod 231 is clamped and fixed by using tools such as pliers, and then the drive motor 223 is controlled to rotate in the opposite direction, so that the drive motor 223 can drive the transmission gear 222 to rotate through the connecting gear 221 and the transmission belt 224, so that the transmission gear 222 drives the installation cylinder 23 to rotate; because the assembly rod 231 is clamped and fixed, the assembly rod 231 and the installation cylinder 23 rotate relative to each other, so that the assembly rod 231 rotates in the opposite direction and moves out of the installation cylinder 23 extends outward, thereby removing the assembly rod 231. Similarly, when the assembly rod 231 needs to be installed, it is only necessary to control the drive motor 223 to drive the installation cylinder 23 to rotate forward, so that the clamped assembly rod 231 and the installation cylinder 23 rotate first, and the assembly rod 231 can be tightened into the installation cylinder 23; thereby, the number of water meters assembled per day can be increased or decreased according to market demand by changing the number of assembly rods 231. That is, when the market demand for water meters 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 further improving the production efficiency of the water meters; in the season when the demand for water meters is low, by removing and storing the assembly rod 231, the time cost and maintenance and management cost increased due to too many tightening stations can be reduced, thereby improving the profitability of the enterprise; so that the actual application effect of the present invention is effectively improved.

[0022] As an embodiment of the present invention, a hinge groove 26 is formed on the upper end surface of the positioning plate 253; a hinge plate 261 is rotatably connected in the hinge groove 26; and the hinge plate 261 is rotatably connected in the hinge groove 26 via a torsion spring.

[0023] As an embodiment of the present invention, a groove 27 is formed 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 in one end of the blocking block 271 close to the bottom of the groove 27; and an electromagnetic plate 273 is embedded in the bottom of the groove 27.

[0024] As an embodiment of the present invention, the end of the positioning plate 253 away from the pneumatic push rod 251 is fixedly connected with an elastic block 28; the elastic block 28 is made of fluororubber material; the surface of the limiting plate 24 is covered with a shell 29; the shell 29 is made of PTFE material; During operation, since the pipe joints of different types of water meters to be assembled have different heights, in order to ensure that the positioning plate 253 can effectively limit and clamp the pipe joints of different heights, the present invention provides 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 first contact the pipe joint of the water meter to be assembled, so that the circular outer surface of the pipe joint of the water meter to be assembled is blocked by the hinge plate 261, so that The hinged plate 261 can overcome the torsion force of the torsion spring under the obstruction of the pipe joint of the water meter to be assembled and rotate in the direction close to the positioning plate 253 until the hinged plate 261 is blocked by the groove wall of the hinge groove 26, so that the groove wall of the hinge groove 26 supports the hinged plate 261, so that the positioning plate 253 can effectively clamp and limit the pipe joint at the higher position angle of the water meter to be assembled through the hinged plate 261; if the position of the pipe joint of the water meter to be assembled is lower, 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 25 in the groove 27 271 goes beyond the positioning groove 25 and is located between the two limiting plates 24; in the initial state, the blocking block 271 is adsorbed on the bottom of the groove 27 by the magnet 272, so that the blocking block 271 penetrates into the groove 27; at this time, the electromagnetic plate 273 is energized, so that the electromagnetic plate 273 generates the same stimulation as the magnet 272, so that the magnet 272 moves away from the electromagnetic plate 273 under the push of the magnetic repulsion 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 in the end of the blocking block 271 close to the bottom of the groove 27, the magnet 2 72 can push the blocking block 271 to extend in a direction away from the bottom of the groove 27 under the action of the magnetic repulsive force, so that the blocking block 271 extending out of the groove 27 can be driven by the positioning plate 253 to approach the pipe joint of the water meter to be assembled, 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 joints at different heights 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, so that the practical application scope of the present invention is effectively improved; thereby improving the practicality of the present invention; In the initial state, the reason why the positioning plate 253 is pulled by the pneumatic push rod 251 and is located in the positioning groove 25 is that when the user places the water meter to be assembled between the two limit plates 24 and slides, the water meter to be assembled will be affected by human errors and be in a slightly tilted state. At this time, the pipe joint close to the light rod 13 is tilted toward the limit plate 24 on one side and slides in contact with the limit plate 24. If the positioning plate 253 extends out of the positioning groove 25, the pipe joint of the water meter to be assembled that is in sliding contact with the limit plate 24 will move to the positioning groove 25 under the conveyance of the conveyor belt 111, resulting in a collision between the positioning plate 253 extending out of the positioning groove 25 and the pipe joint of the water meter to be assembled, so that the pipe joint of the water meter to be assembled is blocked by the positioning plate 253 and affects the normal movement of the pipe joint transported by the conveyor belt 111. Therefore, by arranging the positioning plate 253 to be located in the positioning groove 25, it can be ensured that the water meter to be assembled is accurately moved to the bottom of the assembly rod 231 under the conveyance of the conveyor belt 111 for effective assembly, so as to ensure that the present invention can operate normally and stably. The elastic block 28 is fixedly connected to one end of the positioning plate 253 away from the pneumatic push rod 251 because the pipe joint of the water meter to be assembled is cylindrical. When the positioning plate 253 is close to 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 plates 253 of the two limit 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. The elastic block 28 can increase the contact area between the elastic block 28 and the pipe joint of the water meter to be assembled due to deformation, thereby improving the clamping effect of the elastic block 28 on the pipe joint of the water meter to be assembled; it is prevented that when the pipe joint of the water meter to be assembled is clamped, the water meter to be assembled is driven to slide due to the clamping force on the pipe joint, thereby causing the pipe joint to separate from the two positioning plates 253, which not only affects the clamping effect of the positioning plates 253 on the pipe joint, but also causes the water meter to be assembled to be unable to be clamped by the pipe joint and unable to be accurately positioned with the assembly rod 231, resulting in The assembly rod 231 cannot clamp and rotate the water meter cover of the water meter to be assembled through the clamping block 234 at the lower end. Therefore, the setting of the elastic block 28 can improve the stability of the clamping of the positioning plate 253 on the water meter pipe joint to be assembled. The elastic block 28 is made of fluororubber material, so that the elastic block 28 can not only have elasticity, but also have good high temperature resistance and wear resistance. The elastic block 28 of fluororubber can maintain its physical properties and chemical stability at high temperatures and is not easy to age, deteriorate and crack. In addition, since the outer surface of the water meter pipe joint to be assembled is usually provided with threads to facilitate the connection of the water meter to be assembled with the water pipe, when the elastic block 28 clamps the outer wall of the water meter pipe joint to be assembled, the elastic block 28 will contact the outer wall thread of the water meter pipe joint to be assembled; and the elastic block 28 of fluororubber has good wear resistance, so that the elastic block 28 of fluororubber can effectively reduce the wear caused by the outer wall thread of the water meter pipe joint to be assembled during the clamping process, thereby improving the service life of the elastic block 28, so that the practical application effect of the present invention is effectively improved;By providing a shell 29 of PTFE material fixedly connected to the surface of the limit plate 24, the shell 29 can protect the limit plate 24 on the one hand, avoiding scratches or wear on the limit plate 24 due to sliding friction between the water meter pipe joint to be assembled and the limit plate 24, thereby increasing the service life of the limit plate 24. On the other hand, the shell 29 made of PTFE material has the characteristics of smooth surface and low friction coefficient, so that when the water meter pipe joint to be assembled contacts with the shell 29, the friction between the water meter pipe joint to be assembled and the shell 29 can be reduced, which not only reduces the wear of the pipe joint on the shell 29, but also can The influence of friction on the conveyor belt 111 conveying the water meter to be assembled is reduced, and the conveying efficiency of the conveyor belt 111 for the water meter to be assembled is improved. Moreover, the limit plate 24 is in sliding contact with the conveyor belt 111 through the shell 29, which also reduces the wear of the conveyor belt 111 caused by the limit plate 24, and improves the service life of the conveyor belt 111. Moreover, since the limit plate 24 is made of carbon steel material, the shell 29 can protect the limit plate 24 made of carbon steel, reduce the corrosion of the limit plate 24 caused by the outside air, and thus improve the service life of the limit plate 24, so that the practicality of the present invention is further improved. ;
