Embodiment Construction

[0015] Please refer to FIG. 2 , the battery roll core flattening device of the present invention includes a base 1 , a bracket 2 , a driving device 3 , a pressing plate 4 , a disk 5 , a baffle plate 6 and a chute 7 .

[0016] Wherein the support 2 is fixed on the base 1, and the driving device 3 (the present embodiment is a cylinder) is fixed on the support 2 with a certain interval with the base 1. The pressure required for flattening the battery winding core is provided, and the driving device 3 flattens the winding core to be flattened through the pressing plate 4 . The disk 5 is rotatably arranged on the base 1 and is arranged opposite to the pressing plate 4. It is used to flatten the workbench of the winding core. The disk 5 is connected to another driving device (the present embodiment is an air cylinder, not shown in the figure). Rotational power is provided by the driving device, and a baffle 6 and a chute 7 are suspended above the disk 5. The baffle 6 is used to coop...

Abstract

The invention relates to a battery corn flattening device, which comprises base, support, driver, and compressing plate that distantly fixed on support; the compressing plate and driver are connected and opposite on base; the device also comprises rotation workbench, incline groove and baffle plate; the workbench is on the base and opposite to compressing plate; the incline groove and baffle plate are above the base to lead in and out corn. The inventive rotation work bench can effectively reduce flatten time, improve efficiency, and it uses incline groove and baffle plate to lead corn in and out workbench, to improve flatten efficiency.

Description

technical field [0001] The invention relates to the field of lithium ion battery manufacturing, in particular to a flattening device for a wound lithium ion battery core. Background technique [0002] Since the concept of "rocking chair battery" (RCB) was proposed in 1980, Japan's Sony Corporation and Sanyo Corporation began practical research on lithium-ion secondary batteries in 1985 and 1988, respectively. With outstanding features such as large specific energy, small self-discharge, wide application temperature range, stable working voltage, and long storage life, all countries in the world are paying attention to the application of lithium-ion secondary batteries in the field of communications, portable electronic products, electric vehicles, and aerospace. Applications have shown great interest and enthusiasm, and a lot of research and improvements have been made on manufacturing equipment for lithium-ion secondary batteries. [0003] At present, semi-automatic equipm...
