Application of Wecon hmi & plc in lock screw machine

Ⅰ Brief introduction

Automatic locking screw machine is also called automatic feed screw machines, automatic locking screw machine, industrial systems and tighten the screw lock pay robots, is a machine to replace the traditional manual screw down.Manual screw include pure hand tight and electric screwdriver or pneumatic screwdriver screw down , the latter by way of electric or pneumatic rotating power, instead of the frequent hand tighten the action, to some extent alleviate the work intensity of the lock screw, but due to manual screw placement, and on the screw head is still need to work takes up a lot of time and energy, so the overall efficiency is limited.

Ⅱ Operating principle

Automatically lock screw machine contains screw the whole unit, automatic screw conveyor unit and automatic tighten screw unit and test unit in the process of lock.

Screw automatic line unit will column loose screws lined up and a single output.The line units can separate by the vibration plate.Institutional implementation can also through the institution of swing arm screw to implement.Automatic screw conveying unit mainly to transfer the single screw to the before of screw unit.Automatic tighten the screw unit consists of rotation drive part and screw the import parts.Screw import way of common are blowing and adsorption.In general, blowing type due to continuous work, do not need to head back and forth movement, therefore, the overall efficiency is better than that of adsorption.But blowing type itself is limited by a screw shape and length to diameter ratio, not every kind of screw is suitable for blowing type.Detection unit detection problem including leakage locking screws, floating lock, card material, etc

Ⅲ Introduce the program

The application of Wecon hmi in gas burner

Ⅰ Brief introduction

Gas burner valve testing: through this equipment testing,adjust gas burner as soon as possible.

Ⅱ Operating principle

According to the set time delay measurement valve rapid opening and slow opening,measuring whether open the speed of the best results at the same time.

Ⅲ Introduce the program

1.Monitoring screen: this screen is to monitor the rapid stroke actual distance within the set time.

 

2.Rapid feed setting screen: set the upper and lower of rapid feeding and running time.

 

3.Slow feed monitoring screen: monitoring the feed speed of slow feed and setting time.

4.Slow feed setting screen: set the upper and lower of slow feeding and delay time.

 

5. Display screen:displaying the total travel and closing time of valve ,and the total travel,the speed and the time of rapid or slow feed.

Working requirements: by setting rapid or slow feed running time,monitoring rapid or slow feed travel and speed,so to get a better opening results, to make gas burner ignition and combustion can achieve the best effect.

Ⅳ Main points of engineering design

1.Make sure time setting, to monitor measuring values.
2.And then to make sure whether the burner valve opening within the scope of permissible error.

Wecon hmi Muti-link function and settings

Multi-link provides an economical and flexible solution that allows multiple human-machines to communicate with each other via RS485.In the operation of Multi-link, one human-machine works as a the master, the others work as the slave. Only the master can communicate with the PLC and receive data from it. And the slaves all receive data from the master. Therefore, every slave must have its own station number that allows the master to interact with it, which means interacting with the PLC.

Wecon hmi Muti-link settings:

Ⅰ.Connection Mode

An example of communication between a PLC and four human-machines is shown in the figure below. Note that human-machines usually communicate with each other via RS485 and every slave must have its own station number. When the system has just one slave, human-machines can also communicate with each other via RS232.

Ⅱ. Parameter settings of Multi-link Communication

Here are the operation procedures of setting communication parameters of Multi-link.

1.Select 【System Parameter】/【Connections and communication】, then select “add” in the screen. Select communication interface of Multi-link in the option of “communication interface” and “Multi-Link Protocol”in the option of “device type”.

2. Set the parameters of the master and the slave，the corresponding number and station number of the slave. 

Notes: 

The more slaves, the slower the communication speed may be. 

The station numbers of the slave must be consecutive numbers starting from one without repeating. 

The parameters of the master and the slave must be the same.

The order of the protocol must be the same when choosing the protocol of the master and the slave.

3.After setting the parameters above, select【Tool】/【Project Build】.Then you can download it to the human-machine.

Multi-Link Protocol settings: 

Notes:  If a system has one master and slaves, we should change the number of the slave in the option of master setting 

 and change the HMI station number in the option of slave setting. 

The station number of HMI increase by one, that is if the number of the slave is two, then the station number of the first slave is one and the second slave is two, etc. Other settings are the same as above.

Ⅲ. Notes

    Please note the following points when using Multi-Link.

1. Please make sure that the projects of the master and the slaves are the same except the parameters of them.

2. The external address used in the scripts must be added to 【Project Configuration】/【System Parameter】/【Multi-Link Extra Address】when using scripts.

3. The interface parameters of the master and the slaves must be the same.

4. The order of the protocol must be the same when choosing the protocol of the master and the slaves.

5. The station numbers of the slaves must be consecutive numbers starting from one without repeating.

6. The more slaves, the slower the communication speed may be.

7. Suggest communicating via RS485 when selecting Multi-Link Protocol. When the system has just one slave, human-machines can also communicate with each other via RS232.

8. The external address used in the scripts must be added to 【Project Configuration】/【Multi-Link Data Area】.

Syringe pump is mainly used in the medical device to control syringes.

WECON touch screen hmi LEVI 430T and the single-chip microcomputer constitute a control system, with custom commands. Through the touch screen, commands are given to the single-chip microcomputer to control the movement of the pump, which thus control the operation of the syringe.

(2) Main Screen of WECON touch screen hmi

2.1 Main Screen

The main screen is setting screen, including patterns, flow rate, volume, and time.

2.2 Mode Screen

There are two main modes for the mode screen: push and pull.

2.3 Flow rate screen

To set the parameters of the flow rate

2.4 Capacity Screen

Same as the mode screen, it provides two capacity options.

2.5 Monitor screen

      This screen is mainly used to feed back the single-chip microcomputer data for monitoring.

      It has rate, pattern, flow velocity, time, the running time and the remaining time

(3) Conclusion

WECON touch screen hmi has comprehensive functions, is reliable and durable.
