The described lithium battery pole ear ultrasonic bonder having dedusting function, is characterized in that, described multilayer binding dust gummed paper total thickness 0.02 ~ 10mm, individual layer binding dust gummed paper thickness range 0.02 ~ 0.1mm.
The described lithium battery pole ear ultrasonic bonder having dedusting function, is characterized in that, described dust retaining groove left and right length, front and back width and altitude range are determined by lower welding head size,
The described lithium battery pole ear ultrasonic bonder having dedusting function, is characterized in that, described dust retaining groove adopts a kind of material in PVC, stainless steel, aluminium or copper to make.
The lithium battery pole ear ultrasonic bonder of dedusting function that has described in utilization carries out the method for the dustless welding of lithium battery pole ear, it is characterized in that, comprise following step, when described lithium battery pole ear welds, the welding slag that welding produces is blowed to the sticky paper in ultra-sonic welded dust retaining groove by blowning installation, welding slag is clung by binding dust gummed paper, is torn to weld by dust retaining groove inwall upper strata binding dust gummed paper after having welded next time.
Advantage of the present invention and effect are:
1. the present invention installs dust retaining groove by around ultrasonic wave lug welder soldering tip, and the welding slag that can effectively prevent tab welding from producing splashes on a large scale, causes welding slag not easy to clean.
2. dust retaining groove inwall of the present invention posts multilayer binding dust gummed paper, gummed paper has caking property one outward facing sides, gummed paper can cling the welding slag that tab welding produces, and prevents welding slag from flying into other position and causes secondary pollution, improve security performance and the self-discharge performance of battery.Multilayer binding dust gummed paper is disposable is in addition installed on dust retaining groove inwall, tears one deck after each use, convenient to use.
3. install blowning installation above ultra-sonic welded soldering tip side of the present invention, the welding slag that welding can be made to produce when tab welding is blown flies towards direction in dust retaining groove, effectively can control welding slag and pollute.
