First, the basic knowledge of copper wire and copper sheet welding machine welding
Copper wire and copper sheet welding machine is the use of high-frequency vibration wave transmission to the two metal surfaces to be welded, in the case of pressure, so that the two metal surfaces rub against each other to form a fusion between molecular layers, its advantages are fast, energy-saving, high fusion strength, good conductivity, no spark, close to cold processing; The disadvantage is that the welded metal parts cannot be too thick (generally less than or equal to 5mm), the solder joint position cannot be too large, and it needs to be pressurized.
Second, the advantages of copper wire and copper sheet welding machine:
1) The welding material is not melted and does not have fragile metal characteristics.
2) Good conductivity after welding, very low or almost zero resistivity.
3) Low requirements for the surface of the welded metal, oxidation or electroplating can be welded.
4) Short welding time, no need for any flux, gas, solder.
5) No spark welding, environmental protection and safety.
Third, copper wire and copper sheet welding machine welding characteristics:
Small size; light weight; Beautiful appearance, good conductivity after welding; Welding is safe and reliable, and does not change the structure of the metal itself of the welding object; High welding quality, high degree of automation of welding machine; Good welding consistency; Quality is guaranteed.
Copper wire copper sheet welding machine is an extension of ultrasonic metal welding machine, also called ultrasonic metal spot welding machine, ultrasonic metal welding equipment, ultrasonic metal welding machine, etc. The equipment can be used to weld the welding between the copper wire and the copper sheet within 30 square meters, the impedance of ultrasonic welding is almost close to zero, compared with traditional welding, the welding place does not heat up.
Ultrasonic metal welding principle of copper wire copper sheet welding machine: ultrasonic metal welding is the use of energy generated by high-frequency vibration, the same or dissimilar metals, under appropriate pressure, through cold grinding and horizontal movement to infiltrate the surface molecules of the material to achieve the purpose of welding.
Welding advantages: 1, the welding material is not melting, not fragile metal characteristics. 2, good conductivity after connection, resistivity is extremely low or almost zero. 3. Low requirements for welding metal surface, oxidation or electroplating can be welded. 4. Short welding time, no need for any flux, gas, solder. 5. No spark in welding, environmental protection and safety.
Ultrasonic metal welding applicable products: 1, nickel oxide battery nickel mesh and nickel sheet mutual fusion. 2, lithium battery, polymer battery copper foil and nickel sheet mutual fusion, aluminum foil and aluminum sheet mutual fusion. 3. The wires are mutually fused, deflected into one and multiple interfusions. 4. The wire is mutually fused with various electronic components, contacts and connectors. 5, all kinds of home appliances, large heat sink for automotive supplies. 6. Electromagnetic switch, fuseless switch and other high-current contacts, mutual fusion of dissimilar metal sheets. 7, the sealing of the metal pipe, cut can be watery, airtight.
It is suitable for welding lithium battery pole pieces, dielectric capacitors, relays, transistors, electrical wiring blocks, thermocouples, thyristor components, chillers, etc. Ultrasonic metal welding is an efficient and highly reliable welding method.
Peculiarity:
(1) The two welded objects overlap, and the solid form is synthesized by ultrasonic vibration and pressing, the joint time is short, and the joint part does not produce casting structure (rough surface) defects. (2) Compared with ultrasonic welding and resistance welding methods, the mold life is long, the mold repair and replacement time is less, and it is easy to achieve automation. (3) Ultrasonic welding can be carried out between different metals of the same metal, which consumes much less energy than electrical welding. (4) Compared with other pressure welding, ultrasonic welding requires less pressure and the amount of deformation is below 10%, while cold pressure welding has a workpiece deformation of 40%-90%. (5) Ultrasonic welding does not require pretreatment of the welded surface and post-welding treatment like other welding. (6) The treatment of ultrasonic welding does not require external factors such as flux, metal filler, and external heating. (7) Ultrasonic welding can minimize the temperature effect of the material (the temperature of the welding area does not exceed 50% of the absolute melting temperature of the metal to be welded), so as not to change the metal structure, so it is very suitable for welding applications in the field of electronics
