Description

Ultrasonic welding head structure Technical Field The utility model relates to the technical field of welding, in particular to an ultrasonic welding head structure. Background The ultrasonic welding head is a key component in ultrasonic welding equipment, is also called an ultrasonic welding die or an ultrasonic vibrator, is widely applied to welding of materials such as plastics and metals, is commonly used for connecting plastic components in the industries such as automobile parts, electronic and electric appliance shells, medical equipment and toys in the aspect of plastic welding, and can be used for welding lithium battery pole pieces, electronic element pins, precision metal parts and the like in the field of metal welding. The welding tool is generally made of high-strength and wear-resistant metal materials, such as titanium alloy, aluminum alloy or tool steel, and the like, and is mainly used for transmitting high-frequency mechanical vibration energy generated by an ultrasonic transducer to workpieces to be welded, and the surfaces of the workpieces are rubbed with each other through the high-frequency vibration to generate heat, so that the workpieces reach a melting point on a contact surface and are fused together, and the purpose of welding is achieved. The ultrasonic energy loss is large when the existing ultrasonic welding head welds metal, the service life of the ultrasonic welding head is short, and the manufacturing cost is further increased. Disclosure of utility model Based on this, it is an object of the present utility model to provide an ultrasonic horn structure to solve the technical problems mentioned in the background art. In order to achieve the purpose, the ultrasonic welding head structure comprises a handle, wherein one end of the handle is provided with a welding head, two ends of the welding head are provided with transmission rods, the other end of each transmission rod is provided with a handle, the inner wall of the welding head is provided with a middle hole, two ends of the welding head are provided with welding surfaces, and the surfaces of the welding surfaces are provided with a plurality of groups of welding tables. Through adopting above-mentioned technical scheme, through the setting of multiunit welding bench, two welding heads, can positive and negative application, the indirect welding life-span that improves, the welding teeth of welding bench is the quadrangular frustum, the effectual product that leads to the product to be rugged and damaged phenomenon that has reduced the welding product welding teeth, make the product plane that welds out smoother, the firmness is higher, be particularly suitable for being used for the metal foil welding, through the setting of centre bore, the centre bore is arranged in ultrasonic wave bonding tool center department, because the amplitude is left and right sides reciprocal amplitude, when the welding head welds the object downwards, welding stress can prolong the welding bench to both ends diffusion, part upward stress can be blocked by the centre bore and transmit opposite side bonding tool department, thereby make ultrasonic wave bonding tool welding more steady, and extension ultrasonic wave bonding tool life-span. The utility model further provides that the welding teeth of the welding table are quadrangular tables. Preferably, the phenomenon that the welded product is uneven and damaged due to welding teeth of the welded product is effectively reduced, so that the welded product is smoother in plane and higher in firmness. The utility model further provides that the handle, the transmission rod and the welding head are of an integrated structure. Preferably, the service life of the welding head is effectively prolonged.
