Automatic detection line and detection method for pole piece defects of power lithium-ion batteries

Abstract

The invention discloses an automatic detection line for power lithium ion battery pole piece defect and a detection method. The automatic detection line comprises a feeding mechanism, a visual detection mechanism, a qualified product discharging mechanism and an unqualified product discharging mechanism which are arranged on a speed chain along the moving direction, and a control mechanism. The detection method comprises the steps of feeding, detecting, discharging qualified products and discharging unqualified products. The invention has the advantages of high detection efficiency, low using cost and standard and uniform product quality.

Description

technical field

[0001] The invention relates to an automatic detection device and method, in particular to an automatic detection line and detection method for pole piece defects of power lithium-ion batteries. Background technique

[0002] With the rapid development of human economy, the problems of environmental pollution and energy shortage have become increasingly prominent. In order to cope with the dual pressure of emission reduction and the increasing scarcity of oil resources, most countries in the world regard the development of new energy vehicles as an important way to revitalize the automobile industry and energy conservation and emission reduction. At the same time, military, aviation, medicine and other fields also put forward new requirements for large-capacity batteries. Because lithium-ion batteries have many advantages such as high specific energy, wide charging power range, long cycle life, good rate discharge performance, no memory effect and no pollutio...

Examples

Embodiment

[0029] Example: such as figure 1As shown, the automatic detection line for pole pieces of power lithium-ion batteries in this embodiment includes a feeding mechanism 2 arranged along the running direction of the tooling plate 1-1 on the double-speed chain 1, a visual inspection mechanism, a qualified product unloading mechanism 5, and a disqualified product. Product unloading mechanism 6, and control mechanism.

[0030] For the feeding mechanism, the unqualified product unloading mechanism and the unqualified product unloading mechanism, since they have the same structure, the first beam, the second beam, and the third beam are collectively referred to as beams below, and the first lifting mechanism, the second The second lifting mechanism and the third lifting mechanism are collectively referred to as the lifting mechanism, and the first translation mechanism, the second translation mechanism, and the third translation mechanism are collectively referred to as the translation...
