SMT Feeder
The SMT feeder is one of the main parts of SMT pick and place machine, and it is also an important part in surface mount technology that affects the placement capacity and production efficiency. It is mainly divided into stick feeder, tape feeder, tube feeder and tray feeder.
The more common feeder brands in the market are JUKI Feeder , Samsung Feeder, Yamaha Feeder, FUJI Feeder, Fuji NXT/SIM feeder, Panasonic Feeder, i-Pulse feeder, ASM Siplace feeder and so on. We can supply almost all models feeder, original feeder ones or copy / repalcements feeder , used feeder or new feeder.
Now Yamaha, Juki and Samsung electric feeders made in China can replace the pneumatic feeders, whicn are more stable and precise. if you are interested, welcome inquiry.

Description of the Invention The utility model relates to an IC card intelligent hot water meter, in particular to a meter integrated hot water meter based on RFID and NFC technology.
BACKGROUND OF THE INVENTION In recent years, the shortage of water resources has made people's awareness of water saving more and more intense. In order to strengthen the management of water resources to avoid the waste of water resources caused by human factors, the use of water control equipment is particularly important.
At present, the common water control equipment is mainly an offline integrated timing water control equipment and an off-line split-time clocking water control equipment. The equipment deducts the balance in the card according to the length of water usage at a certain rate. Because the billing method is timed, the change of the water pressure or the valve body diameter will result in a large difference in the amount of water flowing out at the same time, and there are certain deficiencies in the way of billing, so it needs to be improved.
At this stage, the water control equipment is basically offline. Data cannot be exchanged or shared between equipments. It is not conducive to the control of water resources. At the same time, common water control equipment only supports the MIFARE standard S50 and S70 cards. Limited.
SUMMARY OF THE INVENTION The purpose of the invention of the present invention is to overcome the deficiencies of the prior art and provide an S50, S70 card, and a CPU card that can combine offline and networking functions and can recognize the MIFARE standard at a frequency of 13.56M. , (U) SIMPASS, RF-(U)SIM, NFC and IC card smart hot water meter with flow meter fee.

Compared with the prior art, the beneficial effects of the present invention are: the IC card smart hot water meter integrates an NFC identification technology and an IC card identification technology, and adopts a M0 core processor, and the processing speed reaches 50 MHz, and the embedded real-time operation is transplanted. The system improves the security, stability, and reliability of the entire equipment system. It adopts a flow meter fee method to improve the accuracy of billing. It uses RS485/232 communication to implement data exchange and sharing in real time with the database, preventing data. Loss, improve security; At the same time using multi-function LCM LCD display as human-machine interface, design more humane, more convenient and intuitive operation. At the same time, the utility model combines the networking and offline functions into one and greatly expands the application.

[Meter's latest patent] IC card smart hot water meter
[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduce a national patent for invention of invention—IC card smart hot water meter. The patent was applied for by Chengdu Card Intelligent Technology Co., Ltd. and it was authorized on January 4, 2016. In order to solve the above technical problems, the present invention is implemented by the following technical solutions: The utility model of the smart hot water meter IC card, from the hot water meter housing 1, multi-function LCM liquid crystal display 2, IC card holder 3 , control circuit 4, power indicator 5, power supply and communication interface 6, smart card reader antenna board 7, solenoid valve 8, water meter base meter 9, hot water meter base 10, power supply and communication cable outlet 11 and mounting hook Hole 12 consists. One end of the power cord is connected to the IC card intelligent hot water meter through the power supply and communication interface 6, and the other end is connected to the power via the power supply and the communication line cable port 11. One end of the communication line is connected to the IC card intelligent hot water meter through the power supply and the communication interface 6, and the other end Through the power and communication line cable port 11 connected to the computer; multi-function LCM LCD display 2, IC card holder 3 embedded in the hot water meter housing 1; control circuit 4, power indicator 5, power supply and communication interface 6 and The smart card reader antenna board 7 is embedded in the rear end of the hot water meter housing 1; the solenoid valve 8, the water meter base watch 9 is embedded in the hot water meter board base 10, and the hot water meter base 10 is provided with a power supply and communication line at the rear end. Line port 11 and mounting hook hole 12 . When the power is turned on, the power indicator light 5 lights up, the upper row of the LCM LCD screen 2 shows the time, the lower row shows the balance and the unit price, and the system starts to enter the running state.
