Solutions to the failure of the mask machine (6)

The mask machine is the main equipment for manufacturing masks. After a long time of use, some minor problems or malfunctions will occur more or less. How to solve the malfunction of the mask machine so that it can work normally? Strong H Machinery Technology Co., Ltd. provides you with the following solutions:

Fault nineteen:The current is too large and overload (above 7A) during welding.

Cause Analysis:

1. The air pressure is too high;

2. The output gear is too large and the impact current is large;

3. The buffer is too small;

4. High trigger pressure and long delay time.

Fault twenty:There is no ultrasonic output and ultrasonic welding cannot be performed.

Cause Analysis:

1. The ultrasonic crystal board is broken;

2. The ultrasonic vibration plate is broken;

3. Welding overload protection;

4. The output circuit fuse is broken.

5. The gear switch is at 0 position or the contact is not good;

6. The output circuit is not connected well or short-circuited.

Fault twenty one:The size of the joint surface is not uniform.

Solution:

1. Redesign the joint surface.

2. Check the operating conditions.

(1) The workpiece is too tight

1. Relax the fit of the workpiece.

2. Relax the tolerance of the workpiece.

(2) The workpiece cannot be aligned after welding, and the workpiece is not aligned when combined.

Solution:

1. Add a fixed pile between the two pieces of work.

2. If possible, design tools to correct.

(3) Improper support of the base

 Solution:

1. Redesign the appropriate support fixture to raise the base where necessary.

2. If the bakelite is inclined, add a hard bracket.

(4) Curved side walls

 Solution:

1. Increase ribs on the side wall of the workpiece.

2. If the bakelite is inclined, add a hard bracket.

(5) The tolerance of the workpiece is too large

 Solution:

1. Tighten the tolerance of the workpiece.

2. Check the operating conditions.

(6) The internal parts are damaged during welding, and the welding time is too long.

Solution:

1. Increase the amplitude or pressure to reduce damage to the welding time.

2. Adjust the buffer speed and delay time.

Fault twenty two:Welding time is too long.

Solution:

1. Increase the pressure or amplitude to reduce the welding time.

2. Adjust the buffer pressure.

(1) The contact surface of the welding head, workpiece, and base is poor in fit.

Solution:

1. Check the parallelism between the welding head and the base.

2. Check the fit between the welding head and the workpiece.

3. Check the fit between the workpiece and the base.

4. Level up the base where necessary.

(2) The influence of workpiece deformation is too great.

Solution:

1. Reduce the influence of deformation.

(3) The welding time is too long

Solution:

1. Reduce welding time.

(4) The workpiece absorbs too much energy

Solution:

1. Lock the welding head; reduce the amplitude.

2. Press the sonic check button and adjust the sonic adjustment screw to minimize the current indication;

3. Replace the mold;

4. Replace related parts;

5. Overhaul the power tube;

6. Overhaul the power amplifier circuit.
