Ultrasonic solders the working principle of machine

Supersonic wave solders the working principle of machine is: It is to pass oscillating circuit oscillation to give high frequency signal to be changed into mechanical energy by transducer (namely the high frequency machine that frequency exceeds person ear hearing to threshold is oscillatory can) , this energy conducts plastic workpiece to go up through solder head, the vibration that goes up hundred thousands of times with every second adds upward pressure to make the joint face of plastic workpiece fuses after acuteness attrition. The brief pressure on workpiece is maintained to make two weldment link means with the element after vibration stops caky for an organic whole. Average weld time is less than 1 second, what get solder intensity can be rivalled with noumenon photograph. Ultrasonic is plastic solder machine is usable at thermoplastic pair of plastic solder, also use at the treatment craft such as riveting solder, spot welding, built-in, excision. Will design the size of the mould, form according to the exterior of the product.

Ultrasonic is plastic solder machine is usable at thermoplastic pair of plastic solder, also use at the treatment craft such as riveting solder, spot welding, built-in, excision. Will design the size of the mould, form according to the exterior of the product. Ultrasonic is plastic solder machine reach the composition such as tool head and machine by generator of baric transmission system, control system, ultrasonic, transducer. 1, pneumatic transmission system includes to have: Cross Hu implement, pressure-relief valve, oily mist implement, commutator, throttle, air cylinder. When the job above all by air cylinder of stroke of pneumatics machine drive, move in order to drive system of supersonic transducer vibration up and down, the ultrasonic of the small-power in moving force atmospheric pressure to be in solders in atmospheric pressure needs setting according to soldering. 2, system of control system control is comprised by time relay or timer of integrated circuit time. Main function is: It is work of system of transmission of control atmospheric pressure, when making its solder, gas district valve is opened below time control, air cylinder pressurization makes solder head drops, pin with constant pressure by solder thing, protect after soldering approach period of time, control a system to will enrage road valve inverting next, make solder head picks up restoration; 2 it is working hours of control ultrasonic generator, this system makes whole solder the process implements automation, pushbutton is started to produce to spark only when the operation pulse, can be over automatically in this second solder whole process. The order of whole control system is: Power source is started spark system of transmission of control signal atmospheric pressure, head of solder of air cylinder pressurization drops and pin solder to spark supersonic generator works, blast off supersonic maintain purify of proper weld time supersonic blast off continue to maintain constant pressure time to retreat pressure, solder head picks up solder end. 3, ultrasonic generator (1) the ultrasonic with greater power is plastic solder machine, generator signal uses frequency of lock photograph type to dog automatically circuit, the frequency that makes generator is outputted basically agrees with transducer resonance frequency. (2) power is in the ultrasonic of 500W above is plastic solder machine place uses oscillator of self-excitation type power with generator, also have certain frequency traceability. 4, ultrasonic solders machine use acoustics system, basically transducer and tool head are formed. One, open power source not to have indication reason: Fuse fusing means of settlement: 1, examination power is in charge of whether short circuit 2, change fuse 2, ultrasonic test shows an account without electric current: 1, power is in charge of burn down 2, high-pressured capacitance burn down 3, relay controls line section to have breakdown means of settlement: Change spare parts of relevant burn down 3, remove sound wave to check electric current to slant reason of big, overload: 1, solder head does not have locking or have flaw 2, if do not carry solder head, electric current is big, this transducer or ageing of 2 class lever or have flaw 3, power canal character has mutation or burn down 4, part of power enlarge circuit has breakdown means of settlement: Change relevant spare parts 4, the electric current when soldering slants reason of big, overload: 1, baric on the high side 2, solder head is too big, impulse current is big 3, spark pressure is high, defer time is long 4, 2 class staff runs than means of settlement of on the high side: 1, air low pressure 2, use relatively high-power type 3, key is low spark pressure, reduce defer time 4, change with low multiple 2 class lever 5, spark spark switch solder head does not fall reason: 1, stop switch urgently not restoration 2, spark switch cannot spark at the same time or contact among them undesirable 3, programme controll board have problem means of settlement: 1, will stop switch restoration urgently 2, detect make two spark switch can spark at the same time 3, detect program board removes trouble, the average issue that it is IC 6, spark spark after switch, supersonic time is very long or dwell time is very long reason: Weld time or means of settlement of open circuit of switch of dwell time wave band: Adjust contact of wave band switch, made contact is good 7, spark spark after switch, ultrasonic cannot spark reason: 1, pressure sparks switch damages 2, program board has problem means of settlement: 1, change pressure sparks switch or small bedspring 2, detect program board removes trouble, metal of ultrasonic of the average issue that it is IC solders the working principle of machine: Bring to bear on when ultrasonic generator power at transducer, the vibration of transducer gets through luffing lever mechanical amplitude magnifies, send tool head; Strong supersonic and oscillatory force is added below perpendicular pressure action be gotten on by solder content, make the generation between two metals high frequency rub sassafras. Change character, as a result of the result of the joint action of supersonic and oscillatory force and perpendicular pressure, make should be diffused each other by atom of the metal inside solder area, or be close to each other solid state joint undertakes below condition, make range of two metals solder occurred join thereby. Suitable scope: Ultrasonic metal solders is a kind of environmental protection, energy-saving, efficient, high reliability solder method, the line that can use extensively at the metallic stuff such as copper, aluminous, nickel, belt, piece, of the different technology of the appearance such as net, foil solder. Solder in ultrasonic machine machine is used below, to having the ultrasonic model welder of breakdown, should not be eager to starting work, should enquire the around course that produces breakdown and breakdown phenomenon first. To not be very familiar ultrasonic model welder, still answer to be familiar with circuit principle and structural characteristic first, abide by corresponding regulation. Means of the function that before disassembling, wants to be familiar with every electric component adequately, position, join and with all round the relation of other parts of an apparatus, below the circumstance that does not have assembly drawing, answer to disassemble at the same time, draw sketch at the same time, note sign. First exterior hind the ultrasonic that interior should check a maintenance first sets stock not to have apparent maintenance the history, supersonic the state when soldering, the temperature of ultrasonic mould, use fixed number of year, check to undertaking inside machine again next. Circumjacent breakdown element should queue up before tearing open, it is the ability after the breakdown inside machine to disassemble certainly, otherwise, ultrasonic nods welder to disassemble blindly, the likelihood repairs facility worse more. First machinery hind is electric above all after you should remove the issue of ultrasonic mould respect first, have the examination of electric field again. When checking circuit breakdown, should use testing instrument to seek breakdown position, affirm without the contact after undesirable breakdown, again what specific aim ground examines circuit and machinery run a concern, lest miscarriage of justice. The trends after Xian Jing condition is in plastic solder aircraft equipment not when electrify, judge the stand or fall of electric equipment pushbutton, contactor, relay and fuse, decide thereby the place of breakdown. Electrify experiments, listen to its sound, feeling, measure breakdown of parameter, judgement, undertake maintaining finally. Ultrasonic is maintained to solder after cleanness first the electric equipment with heavier to pollution machine, nod to dot of its pushbutton, wiring, contact first undertake cleanness, check exterior control key to whether be out of order. A lot of breakdown are by smudgy reach electric conduction dirt piece causes, once clean breakdown often can eliminate. The basis maintains detailed knowledge is by Weihaihuate limited company of supersonic science and technology is offerred, and to professional production ultrasonic solders machine and plastic solder machine, have a technology masterly support with seasoned technology.
