Maintenance items and precautions of ultrasonic spot welder

During the use of ultrasonic spot welding machine, it is necessary not only to maintain the parts, but also to use the buttons of ultrasonic spot welding machine correctly, which can effectively prolong the service life of the machine. So, what should we pay attention to specifically?



1. Maintenance projects of Ultrasonic spot welder

1) the maintenance method of the bottom die/lower sound pole

Maintenance cycle once a month: if the reticulation wear is not serious, the welding effect is good, no weld, wrinkle, no stick material, the solder joint imprint uniform. Can be changed according to the need or replacement, with carbon paper to check and adjust the level of the bottom die.

2) the amplitude transformer, transducer maintenance methods

Maintenance cycle once a month, check the flange press screw is not loose, add silicone oil to the connecting surface of the transformer rod and welding head.

3) welding head/upper sound pole maintenance method

Positive electrode single ear 60 thousand times, negative single ear 30 thousand times; The positive multi-layer ear 20,000 times, the negative multi-layer ear 10,000 times, if the mesh wear is not serious, the welding effect is good, no virtual welding, no sticky material, can be changed or replaced according to the need.

4) The maintenance method of dust removal of the chassis

Maintenance cycle once every three months: check the electronic components without bursting and burning, reliable aviation plug connection, good grounding, good heat dissipation, no dust in the electrical box, visual inspection, dry air purge.



2. The correct use of the buttons of the ultrasonic spot welding machine can effectively extend the use of the machine

1) Fusion time: that is, the time of ultrasonic emission.

2) Welding time: set the time from the time when the welding head begins to descend to the time when the ultrasonic wave starts to emit. In fact, with the descending speed and buffer, so that the welding head just contact the moment, the ultrasonic wave began to emit.

3) Frequency fine-tuning: select the appropriate welding head output amplitude according to the parameters of the amplitude table to meet the requirements of the workpiece.

4) Curing time: the time from the stop of ultrasonic emission to the beginning of rising of the welding head; During this period of time, the plastic from the molten state, tend to solidify, still need to pass the welding head pressure to the workpiece.

5) Rising speed and falling speed: adjust the rising and falling speed of the welding head, with the use of welding head pressure, the general welding head falling speed should not be too fast, causing stamping damage of the welding surface.



3, the pressure regulating valve filter cup for a long time to drain water, so as not to affect the cylinder.
