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

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】.

WECON hmi touch screen in Threading Machine

The threading machine is also called the tapping machine. It is a kind of fabricating machinery used to cut or form threads, screws, or jaws inside through holes or blind holes of various specifications, such as the body case, equipment surface, nut, and flange plate.

(1) Classifications

According to different driving sources, threading machine can be divided into manual threading machine, pneumatic threading machine, electric threading machine, mechanical mold threading machine and hydraulic threading machine; according to the axis number of the threading machine, it can be divided into single-axis threading machine, two-axis threading machine, four-axis threading machine, six-axis threading machine, and multi-axis threading machine; according to different types of machining parts, the threading machine can be also classified into the mold threading machine, universal threading machine, thermal nut threading machine, flange nut threading machine, round nut threading machine, hex nut threading machine, blind nut threading machine, anti-theft nut threading machine; according to the machining automation degree of the threading machine, it can be divided into full-automatic threading machine, semi-automatic threading machine, and manual threading machine; according to whether the threading machine can tap when it drills, the threading machine is as well divided into drilling threading machine, broaching threading machine, and special threading machine.

(2) System Functional Description

You can enter its tapping depth and thread, or use the touch screen to control its positive and negative rotation. Besides, you can monitor the drill rate, and the actual number of turns in order to increase the working efficiency, and reduce unnecessary trouble of changing the drill direction.

(3) Touch Screen System Features

The threading machine can be divided into four types:

A. Manual operation. Enter positive and negative numbers to servo through touch screen. The servo motor determines the positive or negative rotation. The external buttons close. Tapping stops.

B. Simplicity. The wire threading depth is equal to the number of turns, namely the number of forward turns is the same as that of reverse turns.

C. Precision. Rotate forward for 4 turns and backward for 1 turn. Return after reaching the preset number of turns. The purpose of reverse rotation is to clean up garbage at the drill head.

4 automatic presentation is to repeatedly execute the precision feature.

 

The speeds of tapping and withdrawing threading, as well as threading depth and pitch are set according to the process requirements.

Here you can see all the readings, including the threading drill direction.

(4) Function realization

Manual switch. Enter motor fixed lap 16 000; the motor speed, the pulse signal (address 1298) (external address 1298) and the number of turns are set. In pulsation, press the external switch (address 1567) 1567 rising time = HDX3.0, falling time HDW = 6.0. It begins to rotate, or stops after going 16,000 laps. Enter approximate negative 16,000 for manually reverse and forward rotation. 

 

For simplicity button, when the number of turns and the velocity pulse are equipped, and the external switch is 1567NO, the number of forward turns is equal to that of reserve turns. It rotates until it hits specified numbers of forward and reserve turns.

For Precision button, it refers to four forward turns and one backward turn so that debris wouldn’t pile up. It still needs the pulse model, the number of turns, depth and pitch.

The so-called automatic demonstration is to repeat the precise process, unless the external signal is OFF.

(5) Conclusion

A. It is equipped with text display and the servo so that you can achieve manual operation but cannot realize automatic operation.

B. It has text, PLC and the servo, so the cost is high.

C. It has touch screen, and the servo, which omits the PLC cost, and also looks better than the text display.

The threading machine is cheap. Just the servo coordinates with the touch screen. Currently merchants would like to maximize the benefits. In addition, the class of touch screen is a little bit higher than that of text display. With PLC omitted, it is much more affordable. The operation is simple as well. It can operate only when you enter threading speed, wire retreating speed, depth, pitch and speed reduction ratio. The manual and automatic modes can be switched. it is human and considers diversified choices.
