Treatment of common problems in mask ultrasonic welder

Question:

Ultrasonic welding marks are deep on one side and shallow on the other

terms of settlement:

Adjust the relative level of welding head and welding tooth

Question:

Ultrasonic welding marks are deep in the middle, shallow on both sides, or part of the welding marks are too deep

terms of settlement:

Adjust the relative level of welding head and welding tooth

Question:

Ultrasonic welding marks are deep in the middle, shallow on both sides, or part of the welding marks are too deep

terms of settlement:

1. Check whether the knurled welding teeth are too high and whether the tolerance is a little large, and repair the corresponding welding teeth

2. Use a feeler gauge to measure the gap between the ultrasonic welding head and the welding teeth, compare whether there is a height difference between the positions of deep and shallow welding marks, and grind the corresponding welding teeth

Question:

No ultrasound

terms of settlement:

1. Check the ultrasonic signal line, replace the ultrasonic signal line and replace the ultrasonic generator to locate the problem point

2. Check whether the normally open contact of the automatic line output relay is closed

Question:

Manual ultrasonic, frequency changing, no power output

terms of settlement:

Replace the ultrasonic generator

Question:

No power on, no screen display, no ultrasound

solve the problem:

1. Check the fuse, 250v10a, between the power line connector and the power switch

2. After the fuse tube is replaced, the fuse tube is still burnt out, and the ultrasonic generator is replaced

3. The fuse tube is not burnt out, 220V is normal, replace the ultrasonic generator
