I. what happens if ultrasonic displacement occurs after ultrasonic welding?

 

 

 

Commissioning method:

 

1 reduce welding pressure

 

2. Heighten the bottom formwork to make it more than 2mm higher than the weld

 

3 use ultrasonic conduction welding

 

4 vibration occurs only when the product is molded.

 

5 modify plastic products and enhance positioning

 

II。 40 scratches after ultrasonic welding; Breakage, cracking and scald & 41; What should I do?

 

 

 

Debugging methods of ultrasonic splicer:

 

1 decompression

 

2. Reduce delay time & 40; Early vibration & 41

 

3. Reduce welding time

 

4 cover with protective film

 

5 surface treatment of dies and Fixtures & 40; Hardened or chrome plated &41

 

6. Reduce the number of machine sections or lower the upper mold expansion rate

 

7 for products easy to crack or break, the fixture shall be made into cushion, such as soft resin or cork &40; This item does not affect the welding strength &41

 

8. Add R angle at the right angle of easily fractured products

 

 

 

3. If deformation and deformation are found after ultrasonic welding

 

Commissioning method:

 

1 decompression 40; The pressure should preferably be less than 2kg&41 2 Reduce ultrasonic welding time & 40; Reduced strength standard & 41

 

3. Increase hardening time & 40; At least 0.8 seconds & 41

 

4. Analyze whether the ultrasonic upper and lower molds can be locally adjusted & ＃ 40; If not necessary &41

 

5. Analyze the main causes of product deformation and improve them

 

 

 

4、 Damage of internal parts after ultrasonic welding

 

Commissioning method:

 

1. Early ultrasonic vibration time & 40; Avoid contact with vibration &41

 

2. Reduce pressure and ultrasonic welding time &40; Reduced strength standard & 41

 

3. Reduce the number of machine power segments or low-power machines

 

4 reduce the expansion rate of ultrasonic die

 

5. The stressed part of the bottom formwork shall be padded with rubber

 

6. Avoid hanging or gap between the bottom mold and the product

 

7 horn and 40; Upper die & 41; Retest frequency after hole removal

 

8. Paste elastic material & 40 after the upper mold is de perforated; For example, silicon & 41;

 

5、 After ultrasonic welding, what should be done if burr or overflow is found in the product

 

 

 

Commissioning method of ultrasonic welding machine:

 

1. Reduce pressure, ultrasonic welding time & 40; Reduced strength standard & 41

 

2. Reduce the number of machine power segments or low-power machines

 

3 reduce the expansion rate of ultrasonic die

 

4 use ultrasonic machine for fine adjustment, positioning and fixing

 

5 modify the ultrasonic waveguide fuse

 

 

 

6. What if the product size is unstable after ultrasonic welding

 

 

 

Commissioning method:

 

1. Increase the welding safety factor & 40; According to welding time, pressure and power &41

 

2. Enable the fine adjustment fixing screw & 40; It shall be able to control between 0.02mm and 41 mm

 

3. Check whether the output energy of ultrasonic upper mold is sufficient & ＃ 40; If not, please increase the number of segments &41

 

4. Check whether the fixture positioning and product bearing capacity are stable

 

5 modify the ultrasonic waveguide fuse

 

VII。 If one side is always scalded after ultrasonic welding

 

Ultrasonic vibration welding of ultrasonic welding machine is not a simple linear longitudinal vibration & 40; Deflection and lateral vibration & 41; are not discussed here;, On the contrary, it forms a transverse and longitudinal drop vibration, and the energy at the ultrasonic output end of the upper mold also has certain intensity distribution points, such as air pressure, voltage, machinery, etc. Although it determines the stability of power output energy, the energy distribution point will also increase or decrease in proportion. If it is found that the product is always scalded at one point during ultrasonic welding, it means that the output energy at this point of the upper die corresponds to the stress at this point of the product. At this time, if the contact point of the ultrasonic vibration surface is changed, the scald caused by the thermal cluster can be improved

 

Commissioning method & 40; This method is only applicable to dies &41 2 on a flat surface Die surface treatment & 40; Chrome plated or hardened anode &41

 

3. Cover the plastic bag and stick the protective film on the product

 

4 rotate the upper die 180 degrees
