Embodiment

[0025] The HTPF09140200-20Ah-3.3V laminated soft-pack power battery is welded using the KP2040 ultrasonic tab welding machine of KP The dust retaining groove is composed of three sides and a bottom surface, and the thickness of the dust retaining groove is 10mm. There are 250 layers of adhesive tape on the inner wall of the dust retaining groove. The adhesive side of the adhesive tape is facing the outside. The total thickness of the multi-layer adhesive tape is 5mm, and the thickness of the single-layer adhesive tape is 0.02mm. An air blowing device is installed above the side of the ultrasonic welding head. When the soft-pack lithium battery is welded, the air blowing device blows the welding slag generated by the welding to the sticky paper in the ultrasonic welding dust retaining groove, and the welding slag is stuck by the sticky dust tape. Hold, after the welding is completed, tear off the dust sticky tape on the inner wall of the dust retaining groove. The self-discharg...

Abstract

The invention belongs to the technical field of welding, and relates to a lithium battery tab ultrasonic bonder with the dust removal function and a lithium battery tab dust-free welding method of the lithium battery tab ultrasonic bonder. The lithium battery tab ultrasonic bonder with the dust removal function comprises a bonder body, an upper bonder head of the bonder, a lower bonder head of the bonder and an air blowing device, and is characterized in that a dust blocking trough is installed around the lower bonder head, the dust blocking trough is composed of a left side face, a right side face, a rear side face and a bottom face, a plurality of layers of dust sticking adhesive tape are attached to the inner wall of the dust blocking trough, the sticky face of the adhesive tape faces outwards, and the air blowing device is installed above and on the side of the lower bonder head of the bonder. The lithium battery tab ultrasonic bonder with the dust removal function and the lithium battery tab dust-free welding method of the lithium battery tab ultrasonic bonder have the advantages that because the dust blocking trough is installed around the lower bonder head of the tab ultrasonic bonder, the phenomenon that welding slag generated due to tab welding flies far so that welding slag cannot be easily cleaned away can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of welding, and relates to an ultrasonic welding machine for lithium battery tabs with dust removal function and a method for dust-free welding of lithium battery tabs. Background technique [0002] Lithium batteries in the form of laminations in lithium batteries have good rate performance and high cycle life, and are mainly used in various electric fields, especially in the field of power electric vehicles. [0003] With the rapid development of electric vehicles, electric vehicles have put forward higher and higher requirements for power lithium batteries, especially in terms of safety performance. Lithium batteries must not only have relatively high energy density, but also have good safety performance. . Dust control in the production process of lithium batteries is very important for the safety performance of lithium batteries, especially the welding slag generated during the welding process of the ta...
