Ultrasonic welding machine common fault problems and treatment methods

Ultrasonic welding machines have some common faults, and many of them are troubled by this. Now Altrasonic shares with you how to deal with these problems, hoping to help everyone solve their troubles.

1. turn on the power without display

Reasons: The fuse is blown

Solution: 1. Check if the power tube is short-circuited; 2. Replace the fuse.

2. the ultrasonic test has no current display

Reasons: 1. The power tube is burned; 2. The high voltage capacitor is burnt; 3. The relay control line is faulty.

Solution: Replace the burned parts.

3. the acoustic wave test current is too large, overload

Reasons: 1. The welding head is not locked or cracked; 2. If there is no welding head, the current is large, the transducer or the secondary rod is aged or cracked; 3. The power tube characteristics are mutated or burnt; 4. Power The amplifier circuit is defective.

Solution: Replace the relevant parts.

4.the current is too large when welding, overload

Reasons: 1. The air pressure is high; 2. The welding head is too large, and the inrush current is large; 3. The triggering pressure is high and the delay time is long; 4. The secondary rod ratio is high.

Solution: 1. Reduce the air pressure; 2. Use a larger power model; 3. Reduce the trigger pressure and reduce the delay time; 4. Switch to a low-multiple secondary rod.

5. the trigger switch welding head does not fall

Reasons: 1. The emergency stop switch is not reset; 2. The trigger switch cannot be triggered at the same time or one of the contacts is bad; 3. The program control board has a problem.

Solution: 1. Reset the emergency stop switch; 2. Detect that both trigger switches can be triggered at the same time; 3. Check the program board to troubleshoot, generally IC problem.

6. After the trigger switch, the ultrasonic time is very long or the holding time is very long.

Reasons: The welding time or the holding time band switch is open.

Solution: Adjust the band switch contacts to make them in good contact.

7. After the trigger switch, the ultrasonic wave cannot be triggered.

Reasons: 1. The pressure trigger switch is damaged; 2. There is a problem with the program board.

Solution: 1. Replace the pressure trigger switch or small spring; 2. Check the program board to troubleshoot, generally it is an IC problem.
