Description

Technical Field

[0001] This invention relates to an assembly device for an IoT smart water meter metering display, belonging to the field of intelligent manufacturing assembly technology. Background Technology

[0002] The meter's display is the core component for showing water consumption. It consists of a housing, red and black wheels, red and black wheel needles, a pinion, and a pinion needle, making its structure and working principle complex. Each rotation of the upper-level black wheel causes its rear gear to rotate one notch; each rotation of the pinion simultaneously drives the subsequent pinion to rotate one notch, thus forming a series of rotating wheels for units, tens, hundreds, thousands, and ten thousands, ultimately displaying the water consumption. Existing technology CN203409499U provides a water meter assembly device that primarily uses a robotic arm to grasp and place the digit wheel and toothed wheel. However, during subsequent development, it was discovered that most similar devices still suffer from incorrect orientation of the digit wheel's input column, relatively increasing equipment costs and significantly impacting reliability. The prior art CN108058017B discloses an assembly device for a water meter metering display. The general assembly process is as follows: the open-ended digit wheel boxes are fed one by one into a narrow conveying trough, and the digit wheel boxes on the conveying trough are gradually pushed forward by a pushing device until they reach the digit wheel loading station.

[0003] However, the existing technology has the following problems: In reality, most of the water meter assembly processes are done manually, which is time-consuming, labor-intensive, inefficient, and results in high labor intensity and unreliable assembly quality.

[0048] Based on this, a typical working process of the present invention is as follows:

[0049] When implementing this invention, as follows: Figure 1-18 As shown, the operator stands in front of the manual operation panel 13 and places the empty metering display assembly fixture 29 on the left side of the fixture circulation component 7. When the empty metering display assembly fixture 29 moves to the left end, it will be pushed onto the fixture positioning component 27 until it stops under the limit of the radial positioning block 28. At this time, the clamping block 272 abuts against the side of the fixture base plate 291 under the action of the compression spring. The clamping blocks 272 on both sides abut against each other at the same time, which can fasten the metering display assembly fixture 29. The turntable motor 22 drives the turntable 26 to rotate 45° clockwise through the first synchronous pulley 23 and the second synchronous pulley 25 to reach the first black wheel assembly component 3 station.

[0050] The first black wheel assembly component 3 is mainly equipped with spaced black wheels 16, because their states are consistent. The vibratory feeder sequentially vibrates three parallel black wheels 16 into the through holes on the side of the black wheel guide block 321 until they enter the groove of the black wheel lifting block 326. The black wheel lifting cylinder 325 drives the black wheel lifting block 326 to move upward to a certain position. At this time, the front and rear sides of the black wheel 16 contact the follower wheel 324 and the driving wheel 328 respectively. The stepper motor 332 drives the driving wheel 328 to rotate, thereby driving the black wheel 16 to rotate. When the rear tooth of the black wheel 16 rotates to its top, the black wheel positioning rod 331 restricts the rear tooth of the black wheel 16, thereby restricting the rotation of the black wheel 16. At this time, the positions of the three black wheels are consistent. Next, the black wheel horizontal cylinder 34 drives the black wheel horizontal moving plate 35 to move backward along the black wheel horizontal rail 33. At this time, the middle black wheel suction block 318 is located directly above the black wheel 16. The black wheel vertical cylinder 333 drives the black wheel vertical moving plate 37 to move backward along the black wheel vertical rail 36. The black wheel 16 moves downwards; at this time, the rear teeth of the black wheel 16 are locked in the limiting port 3172, the arc surface of the black wheel 16 is close to the positioning arc surface 3173, a vacuum environment is generated at the vacuum generator interface 3175, and a vacuum suction force is generated through the vacuum channel 3174 to hold the black wheel 16 tightly; the vertical moving plate 37 of the black wheel returns to its original position, the horizontal moving plate 35 of the black wheel returns to its original position, the retraction cylinder 316 drives the side black wheel suction block 317 to retract, and drives the black wheels 16 on both sides away from the middle black wheel 16. The spacing between the three black wheels 16 is the same. At this time, the black wheel 16 is located directly above the metering display assembly fixture 29. The vertical moving plate 37 of the black wheel moves downwards again to the predetermined position, the vacuum generator is turned off, and the three black wheels 16 are placed evenly and stably on the middle black wheel positioning block 295. The teeth on the circumference of the black wheel 16 are in contact with the surface of the contoured tooth groove 2952, and the rear teeth are placed in the wheel axle clearance groove 2953.

[0051] Next, the turntable motor 22 drives the turntable 26 to rotate 45° clockwise to the red wheel assembly component 4 station, and the red wheel 17 is placed on the red wheel positioning block 293 through the same process; the turntable 26 then rotates to the second black wheel assembly component 5 station, and the remaining two black wheels 16 are placed on the middle black wheel positioning block 295 through the same process; the turntable 26 then rotates to the red and black wheel steel needle assembly component 6 station; the red and black wheel clamping component 615 clamps the black wheel 16 and red wheel 17 already placed on the metering display assembly fixture 29 by the downward pressure of the cylinder; the red and black wheel steel needle 15 falls from the steel needle hopper 69 into the steel needle positioning groove 672, and the telescopic rod of the steel needle feeding cylinder 68 extends. The steel needle initial positioning block 67 is pushed forward to the predetermined position. The steel needle lifting cylinder 613 drives the vertical connecting block 611 to move upward along the steel needle vertical rail 610, so that the steel needle lifting block 612 lifts the steel needle located in the steel needle positioning groove 672 until it contacts the bottom surface of the steel needle limiting block 616. The ejector pin insertion cylinder 66 drives the ejector pin fixing block 63 to move forward along the ejector pin insertion rail 62, so that the ejector pin 64 is inserted into the hole of the steel needle final positioning plate 65, and begins to push the red and black wheel steel needle 15 forward. The red and black wheel steel needle 15 passes through the outer shell 14 hole, the red wheel 17 shaft hole, the black wheel 16 shaft hole, and the outer shell 14 hole in sequence, finally completing the insertion and fixing of the red and black wheel steel needle 15.

[0052] Next, the turntable motor 22 drives the turntable 26 to rotate 45° clockwise to the next station. The multi-station moving part 8 pushes the metering display assembly fixture 29 from the turntable 26 to the position corresponding to the pinion assembly part 9 on the circulation track of the fixture circulation part 7. The pinion assembly part 9 places the pinion 19 onto the pinion positioning block 297 for positioning. The multi-station moving part 8 continues to push the metering display assembly fixture 29 to the track position corresponding to the anti-reverse component assembly part 10. The anti-reverse component assembly part 10 places the anti-reverse component at the position of the anti-reverse component auxiliary positioning block 298. The metering display assembly fixture 29 is then pushed to the pinion steel needle assembly. On the track between the mounting component 11 and the pinion pressing and positioning component 12, the pinion pressing and positioning component 12 first presses down the pinion 19, and the pinion steel needle assembly component 11 inserts the pinion steel needle 18 into the outer shell 14 and the pinion 19 for fixation. At this time, the parts inside the metering display are assembled and stop moving as the fixture moves to the upper limit block position of the fixture circulation component 7. The operator removes the assembled finished product from the metering display assembly fixture 29 and places the empty metering display assembly fixture 29 back on the fixture circulation component 7. Finally, the metering display assembly fixture 29 is pushed onto the workstation switching turntable component 2 for repeated circulation.
