FBS series PLC application in the small lead-free wave crest welder

FBS series PLC application in the small lead-free wave crest welder newmaker welcome to e hall exhibition hall 3 PLC PLC programmable controller, PLC controller programming cable. 。 。 one An overview of the crest welder compared commonly big, assembly line production, but some customers such as laboratory, school, small factories need small lead-free wave crest welder. Some electronic equipment factory developed the product, the FBS series PLC and Panelvisa touch-screen. The device needs to control three temperature, a total of three PID, FBS series PLC to realize 8-way most PID, can meet the requirements of the device. Deserve to go up again Panelvisa touch screen, has the very high cost performance. two Process briefly double crest welder must first put the soldering temperature, preheating temperature, preheating temperature compensation, a total of three temperature to the set temperature. When the condition after the establishment, the machine can produce. Put the PCB on the orbit, press start switch, transmission motor running, the pump starts, spray flux, PCB flux coating finish, time delay pump stop. When the PCB to the left after preheating zone, stop transmission motor, PCB in preheating zone, preheating of the countdown, time arrives, transmission, motor start PCB right running, start the spray tin tin pump motor, PCB after preheating temperature compensation area, spray into the tin area, after spray tin area tin pump stop, after the PCB board to the right, transmission motor stops, the cold wind motor startup. Such a complete cycle is over. 3. Hardware configuration input point: detection switch, switch operation, etc. Detection switch quantity are: the right point, left point switch. Operating switch quantity are: start switch, stop switch. Output point: three areas of heating solid state relay, transmission motor and two motors, smoke machine, tin pump pump motor, cooling and electricity self-preservation. Analog input point: the three zone temperature detection. Transmission motor and tin pump require speed, using frequency converter, speed need communication setting. The hardware configuration: FBS - model number function 32 ma 1 master controller, ac 220 v input, FBS - relay output 16 eyt 1 8 x24v, FBS - transistor output module 6 the tc 1 4 channel thermocouple input module four PV057TST 1 Panelvisa touch screen man-machine interface. Programs to write programs to write PLC controller program and touch screen program includes four functions: equipment parameters, alarm query, manual debugging, production picture. Here are some features: equipment every movement can be done in manual debugging images are useful when start debugging equipment and maintenance. Equipment parameters can be set from the touch screen, including temperature, time, coefficient of PID. Alarm query, and can quickly find the cause of the problem. Production pictures is to display the data, production need button in this picture, the convenient user in this picture the three zone temperature, process instructions, and operate in these pictures. Transmission motor and tin pump motor speed setting is set to the PLC touch screen, and then by the PLC through the PORT1 to each motor frequency converter. Use the MODBUS master station functions of the PLC, it is very convenient. Due to the tin pan cooled down over a period of time, set the shutdown button. When click the shutdown button, PLC timing, when the temperature dropped to 80? Cut off power supply. So easy after work, don't have to wait for the temperature down to walk again, more safety. Conclusion PLC in an electronic equipment factory after successful application of precision semi-automatic screen printing machine, and successfully applied to the small wave welding machine. Supply complete sets of equipment manufacturers think, PLC controller and Panelvisa touch screen, the price is very high. This configuration in the future will gradually applied to more devices.
