Abstract

The invention belongs to the technical field of battery processing machinery, and discloses an ultrasonic welding head. The ultrasonic welding head comprises two welding parts, wherein the two weldingparts are arranged opposite to each other in a Z-axis, each welding part comprises two welding head units, the two welding head units are arranged at intervals in the X-axis direction, and a clearance area is formed between the two welding head units, wherein the welding head units comprise a plurality of welding heads, each welding head is provided with a flat head end and a tip end that are oppositely arranged in the Y-axis direction, and the tips of all the welding heads of the same welding head unit are oriented in the same direction. The ultrasonic welding head has the beneficial effectsthat each welding part comprises two welding head units, the two welding head units perform synchronous operation on the same side of a double-core package, the welding head units are provided with the plurality of welding heads with the tip ends, on the one hand, the friction force is greatly increased, on the other hand, the welding heads are provided with the tip ends and the flat head ends, the tip ends can achieve relatively small resistance in the direction towards the tip ends, the vibration is easier, the flat head ends can guarantee the welding strength during welding, and the welding resonance phenomenon is reduced by arranging the clearance area.

Description

technical field [0001] The invention relates to the technical field of battery processing machinery, in particular to an ultrasonic welding head and a welding device. Background technique [0002] At present, in the emerging industry of automotive power batteries, ultrasonic welding has become an indispensable part of the process of making batteries. As the energy density requirements of batteries are getting higher and higher, the corresponding individual batteries are also required to be thicker and larger to meet the higher and higher battery life requirements. The structure of a single battery transitions from a battery shell single-cell package to a double-core package, which can significantly increase the capacity of a single battery cell, but correspondingly increases the welding process. [0003] In the past, the single-core package only needed to be welded once on the positive and negative electrodes to complete the welding process. Now that the core pack is doubl...
