Summary:Wave soldering is the process of forming a specific shape of solder wave on the liquid surface of a solder tank using molten liquid solder and the action of a pump. The PCBA with components inserted is placed on a conveyor chain and passes through the solder wave at a specific angle and immersion depth to achieve solder joint soldering. As a traditional welding technique, wave soldering still plays a positive role in the electronics field, so the intelligence and energy saving of wave soldering equipment are becoming increasingly important. This case uses a Gu Mei touch screenPLC integrated machineFully automatic control of the wave soldering process makes the production process simpler, the process more optimized, energy-saving, and intelligent.

1、 Principle

According to the process flow, the operation of each station of wave soldering equipment is controlled through PLC programming. When a product arrives at the spray position or the wave peak position, it automatically starts the spray and wave peak, and can collect the temperature in real time to PLC, and then transfer it to the touch screen through PLC to achieve real-time temperature monitoring, and can monitor the operation status of each station component in real time.

2、 Advantages

Compared to traditional craftsmanship, it has the following advantages:

1. It can accurately control the on/off time of the tin furnace, melt tin in advance, and solve the problem of users timing the opening and closing of the tin furnace during use. This system also designs three timed on/off times for customers to switch the tin furnace according to normal work, weekend work, and other timed on/off times, which can effectively save customers electricity and time.

2. This system comes with a 4-channel analog input function, which can effectively monitor the preheating temperature and tin furnace temperature in real time. It also has an automatic protection function. When the tin melting temperature in the tin furnace has not reached the set temperature, the peak cannot be manually and automatically started, which provides protection for the product.

3. In the fully automatic state, spray and wave crest are controlled by the product. When a product reaches the spray position, the control system automatically starts spray, and the spray speed can be manually set according to the product width. When the product finishes spray, the spray will be automatically closed, and it will be restarted when another product comes; When the product reaches the peak position, the peak will be automatically activated, and the peak will be automatically turned off after the product welding is completed (can be manually set). Saved soldering flux and electricity, truly achieving energy-saving effect!

4. In manual mode, various components can be manually turned on and off, which can effectively adjust the machine and search for problems.

5. Parameter settings; In the parameter setting screen, you can set the transmission and transportation speed, automatic spray speed, production output, automatic tin furnace switching time, regular maintenance time, etc., which can be added as required.

6. This system has an automatic counting function, which can count the quantity of products and set the output. When the output is reached, a signal is automatically sent to remind customers to count the arrival.

7. This system also has a maintenance expiration reminder, which regularly reminds customers to maintain by setting maintenance times, thereby increasing the service life of the machine.

8. This system also has a password lock function; In this system, there are five periods of regular machine locking function, which customers can choose for themselves. Once the time expires, the machine will automatically stop running, solving the problem of difficult payment for customers.

9. Automatic alarm function, which will automatically sound an alarm when the temperature is too high or too low

3、 Control system

Configuration is availableprogrammable controllerIntegrated with touch screen, it turns the intelligent, automated, and user-friendly performance of wave soldering into reality, with advantages such as high stability, rich functions, simple operation, convenient use, and flexible control

Configuration has4-channel analog input and 2-channel analog output can monitor multiple temperature channels.

4、 Operational performance

1. The touch screen can display in both Chinese and English, with rich display functions, accurately and intuitively displaying the operating status of each workstation of wave soldering, as well as the temperature of the molten tin in the tin furnace, the working status of the heater, the current time, alarm information, etc. Simple operation settings can be made by clicking on the touch screen with fingers, and various adjustment parameters can be checked, set, and modified to achieve human-machine dialogue, which is easy to understand and modifyLearning, easy to remember, simple and convenient to operate.

2. The controller is equipped with a built-in digital clock, and the system can set the on/off time at any time during three working days according to user requirements, saving electricity loss and reducing the cost of heating the tin furnace.

5、 Comprehensive characteristics

1. Adopt programmable controllers andTouchscreen PLC integrated machineThe operating status of the boiler is clearly visible. All operations are easily completed by clicking on the touch screen, and the boiler controller has a complete set of super display and control functions.

2. It can automatically start spray, and automatically close spray after spray, saving raw materials; The fully automatic peak can automatically control the rise and fall of the peak, saving energy! Achieved the effect of saving raw materials and energy.
