Description

Technical Field

[0001] The utility model relates to the technical field of composite current collector roll welding, in particular to a composite current collector device with improved weldability. Background Art

[0002] The composite current collector is a composite material made of raw material films such as PET as the base film, which is deposited on both sides with copper / aluminum molecules through processes such as vacuum coating. It adopts a three-layer composite structure of "metal-polymer material-metal" and forms nano-scale metal on the surface of the polymer PET / PP film through vacuum evaporation, magnetron sputtering and other methods. The metal layer is then deposited and thickened to more than 1μm through water electroplating. The composite current collector has the advantages of energy density, cycle life, safety and battery cost, making it one of the best solutions for improving battery energy density.

[0003] For example, the application number is 202320851077.4, which is a roll welding device for welding composite current collectors. The device uses a rotating motor, a fixing bolt, a rotating shaft, a gasket and a turntable to support the bottom of the composite current collector. The rotating motor drives the rotating shaft and the turntable to perform universal rotation to adjust the position angle of the composite current collector. When changing the welding position, there is no need to manually rotate the composite current collector body, which prevents burns to the arm, saves time and effort, and improves work efficiency. However, it is difficult for the device to position and fix the composite current collector, which makes it easy for the composite current collector to shift during roll welding, affecting the welding effect.

[0004] Therefore, in view of this, research and improvement are conducted to address the shortcomings of the existing structure, and a composite current collector device with improved weldability is proposed. Utility Model Content

The adjustment mechanism 64 includes a screw seat 641 fixedly connected to the upper surface of the sliding placement plate 3. The inner surface of the screw seat 641 is rotatably connected to a second screw 642. The outer cylindrical surface of the second screw 642 is threadedly connected to a second nut seat 643, and the second nut seat 643 is fixedly connected to one end of the positioning rod 61. When rolling the composite current collector, first place the composite current collector on the sliding placement plate 3 by The positioning rod 61 is used for positioning. During positioning, the second screw rod 642 can be adjusted to rotate, driving the second nut seat 643 and the positioning rod 61 to adjust the positioning position. After positioning, the composite current collector is positioned and fixed by the elastic force of the first elastic shaft 62 using the lower clamping plate 63.
