Device and method for testing cast-rolled blank of aluminum foil for power battery

Abstract

The invention discloses a device and method for testing a cast-rolled blank of aluminum foil for a power battery. The device comprises a detection box and a sorting box, a bottom plate is mounted at the bottoms of the detection box and the sorting box, the sorting box is mounted on one side of the detection box, a conveyor belt is mounted at the joint of the bottom plate and the detection box, a feeding port is formed in one side of the detection box, and a first push rod motor is mounted at the top of the detection box. According to the device and method for testing the cast-rolled blank of the aluminum foil for the power battery, the thickness of the aluminum foil blank can be detected through a connecting plate, row columns and limiting blocks, and whether the thickness of an aluminum foil plate is within a specified range or not is detected through the cooperation of the first push rod motor; and aluminum foil blanks which do not meet the standard can be pushed out through a slope and a second push rod motor, blanks which meet the standard can be clamped through a clamping plate and enter the position between a first fixing plate and a second fixing plate, and qualified aluminum foil blanks and unqualified aluminum foil blanks can be conveniently separated.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a testing device and method for casting and rolling blanks of aluminum foil for power batteries. Background technique [0002] In the production process of aluminum foil blank power batteries, the aluminum foil blank used often needs to go through several steps: smelting, casting and rolling, cold rolling, annealing, cold rolling, edge trimming, foil rolling, finished product cutting, and packaging. After the casting and rolling of the aluminum foil blank, it is necessary to check whether the surface of the aluminum foil blank is flat and whether the thickness of the aluminum foil blank meets 7.0±0.1mm. If the surface of the aluminum foil blank is uneven during the casting and rolling process, it will affect the subsequent processing. , making the produced batteries unqualified; [0003] Therefore, a device is needed to detect the effect of the aluminum foil blank after casting an...

[0002] In the production process of aluminum foil blank power batteries, the aluminum foil blank used often needs to go through several steps: smelting, casting and rolling, cold rolling, annealing, cold rolling, edge trimming, foil rolling, finished product cutting, and packaging. After the casting and rolling of the aluminum foil blank, it is necessary to check whether the surface of the aluminum foil blank is flat and whether the thickness of the aluminum foil blank meets 7.0±0.1mm. If the surface of the aluminum foil blank is uneven during the casting and rolling process, it will affect the subsequent processing. , making the produced batteries unqualified;

[0003] Therefore, a device is needed to detect the effect of the aluminum foil blank after casting and rolling, so that after the aluminum foil blank passes through the casting and rolling process, it can detect whether the thickness of the aluminum foil blank belongs to 6.0mm-8.0mm, and screen the qualified and unqualified pieces. At the same time, during the inspection process of the aluminum foil blank, a certain part of the surface of the aluminum foil blank does not meet the specified thickness and needs subsequent processing. When processing it, the entire aluminum foil blank is often reprocessed, and it is not possible to target the non-compliant size. Targeted processing in local areas will waste working time and work efficiency. Therefore, we propose a testing device and method for casting and rolling blanks of aluminum foil for power batteries.
