Recently，A kind of automatic assembly line system for water meter verification of Hangzhou Water Meter Co,.Ltd was granted the patent authorization certificate by the China National Intellectual Property Administration, and our innovative strength and intelligent manufacturing level were officially recognized again!
For a long time, the traditional water meter verification method relies on manual work such as clamping, scanning codes, verifying, calculating and recording, unloading meters, pouring water, recording the performance indicators of unqualified water meters, etc. It is repetitive, mechanical, inefficient, and difficult to scale up production. During the verification process, inconsistent human operations can also affect the accuracy and process completion of the calibration, affecting the performance of the water meter itself and causing many disturbances to the control of the water meter's pass rate.
To address this industry difficulty, our technical team has spent several years continuously tackling it and independently developed the first set of unattended chain plate transmission type pressure and verification pipeline in China, including frequency conversion speed regulating device, fixed code reading device, positioning and counting device before water meter verification, sorting device after water meter verification, and rejecting device for unqualified water meters. It is connected to the fully automatic parallel water meter pressure verification and calibration system and fully automatic serial water meter flow verification and calibration system through the central control system.
In the withstand voltage verification process, it includes processes such as automatic withstand voltage, automatic sorting, and automatic removal. In the flow verification process, it includes automated steps such as meter clamping, leak detection, exhaust, demagnetization, piston return, and pressure relief.
After the pressure and flow tests are completed, the accumulated water inside the watch case is further drained through the water pouring line, and then qualified and unqualified products are automatically sorted and removed.
In short, it is to complete the fully automatic and integrated verification of various performance indicators of the water meter and record the information of various performance indicators on a single assembly line. This device has reshaped the meter verification process, pressing the "intelligent acceleration button" for water meter verification, fully demonstrating our company's "intelligent" manufacturing strength.
In 2018, our fully automatic withstand voltage and calibration assembly line was officially put into operation, becoming one of our six major intelligent manufacturing equipment.
Four major advantages of fully automatic withstand voltage and verification assembly line
Significantly improved verification efficiency
In actual production, this system can replace manual installation, calibration, calculation, recording, and unloading of water meters. It can replace at least 6 people and can measure over 3500 units per day, providing technical support for our company's annual production capacity of over 3 million units.
Intelligence ensures calibration accuracy
This device can achieve intelligent management and automated operation throughout the entire process of identification, transmission, pressure testing, flow verification, result analysis, and result transmission for each meter, avoiding inconsistent results caused by human factors, ensuring inspection accuracy, and a qualified product control rate of 99%.
Multiple models of products can be assembled and calibrated
In the process of automatic assembly and calibration of water meters, it is necessary to ensure that each group of water meters can be accurately positioned, and the inlet and outlet of each water meter can be flexibly docked with the cylinder clamp of the calibration device to protect the fixture tray from any compression stress. This assembly line has replaceable tooling trays that can smoothly place water meters, enabling intelligent assembly and calibration of different types of water meters.
Higher operational safety
The unmanned operation mode avoids personal hazards for workers during pressure testing and flow verification operations, ensuring production safety.
Intelligent manufacturing is the pulse of the Industry 4.0 era, and only through active innovation can it resonate with the times. At present, our company is accelerating the improvement of intelligent manufacturing level and continuously improving the construction of intelligent factories. In the future, intelligent manufacturing will be the golden card of every "Hangzhou Xiaozhuan" that is carefully produced.
