Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] like figure 1 As shown, the electrode assembly alignment detection device described in this embodiment includes an electrode assembly placing unit 3 , a sliding mechanism 2 , a driving unit 1 , an infrared emitting unit 5 and an infrared detecting unit 6 . The electrode assembly placement unit 3 is used to place and fix the electrode assembly 4, and the placement unit can transmit infrared signals. The sliding mechanism 2 is used to drive the electrode assembly placing unit 3 close to the infrared emitting unit 5 . The drive unit 1 is used to slide the sliding mechanism 2 . The infrared emitting unit 5 is used for emitting infrared signals. The infrared detection unit 6 is used to detect infrared signals to detect whether the electrode assemblies are neatly arranged. The infrared emitting unit 5 emits an infrared signal. If the electrode assembly 4 is not aligned...

Abstract

The invention relates to an electrode subassembly alignment detection apparatus and a detection method thereof. The apparatus comprises an electrode assembly placement unit, a sliding device and an infrared detection device, wherein the electrode assembly placement unit is used for placing and fixing an electrode assembly, the sliding unit comprises a sliding mechanism connected with the electrode assembly and a driving unit used for driving the sliding mechanism to move, the infrared detection device comprises an infrared emission unit used for emitting infrared signals and an infrared detection unit used for detecting whether the electrode assembly is tidily arranged through the infrared emission unit, and the infrared signals can penetrate the electrode assembly placement unit. According to the invention, whether the electrode assembly is tidily arranged can be determined through detecting the infrared signals emitted by the infrared emission unit, and if the infrared detection device cannot detect complete infrared signals, an alarm is automatically given. The detection method is simple and fast, and can effectively improve the detection efficiency of the electrode assembly.

Description

[0001] technical field [0002] The invention relates to the technical field of battery detection, in particular to an electrode assembly alignment detection device and a detection method thereof. Background technique [0003] With the rapid expansion of the application of lithium-ion batteries, the technology of lithium-ion batteries is also constantly improving. Lithium-ion batteries can be divided into various types according to the structure of the electrode assembly, including stacked structure, rolled structure and stacked / folded structure. However, in the stacked structure, since the positive electrode, the separator, and the negative electrode constituting the electrode assembly are stacked separately, and multiple electrodes and multiple separators are alternately stacked, it is difficult to arrange the electrode assembly precisely. [0004] The electrode assembly is the main body of the lithium-ion battery, and its quality has a great influence on the performance, ...
