Problems solved by technology
[0003] However, for some workpieces that require large energy for thermal fusion, traditional ultrasonic welding machines often have incomplete melting of the joints of the workpieces to be welded, that is, the energy required for thermal fusion is insufficient, resulting in the welding of the workpieces to be welded in the joint area The degree of firmness decreases, which will seriously cause the workpieces to be welded to be easily separated

Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention provides an ultrasonic hot melting welding method and an ultrasonic hot melting welding assembly. The ultrasonic hot melting welding method comprises the steps that a first hot melting welding piece is placed on a welding platform, and the first hot melting welding piece is provided with a first hot melting nesting position; a second hot melting welding piece is placed on the first hot melting welding piece, and the second hot melting welding piece is provided with a second hot melting nesting position corresponding to the first hot melting nesting position; and the first hot melting welding piece and the second hot melting welding piece are subjected to wrapping and pressing ultrasonic welding operation, and the first hot melting nesting position and the second hot melting nesting position are subjected to wrapping and pressing ultrasonic welding friction. According to the ultrasonic hot melting welding method and the ultrasonic hot melting welding assembly, the first hot melting nesting position on the first hot melting welding piece corresponds to the second hot melting nesting position on the second hot melting welding piece, so that the first hot melting nesting position and the second hot melting nesting position are mutually wrapped and extruded, and the friction area between the first hot melting welding piece and the second hot melting welding piece is increased; and the speed of generating heat at the joint position of the first hot melting welding piece and the second hot melting welding piece is increased.
Description
technical field [0001] The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic hot-melt welding method and an ultrasonic hot-melt welding assembly. Background technique [0002] With the development of welding technology, welding of some non-metallic materials needs to be different from traditional welding technology, for example, ultrasonic welding technology, which converts 50 / 60 Hz current into 15, 20, 30 or 40KHz power. The converted high-frequency electric energy is converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction and melts the plastic. [0003] However, for some workpieces that require large ener...
