Description
Technical field
The present invention relates to battery detecting technical field, be specifically related to a kind of electrode assemblie alignment detection device and detection method thereof.
Background technology
Along with the rapid extension of lithium ion battery applications, the technology of lithium ion battery is also constantly being improved, and lithium ion battery can be divided into multiple according to the structure of electrode assemblie, has stacked structure, curl shape structure and stack/folding-typed structure.But, in stacked structure, owing to constituting the mutually individually stacking of the positive pole of electrode assemblie, barrier film and negative pole, there is multiple electrode and the stacking in an alternating manner of multiple barrier film, thus exist and be difficult to critically proper alignment electrode assemblie.
Electrode assemblie is the main body of lithium ion battery, and its quality has the biggest impact to the performance of battery, cycle life, capacity.Traditional manual detection electrode assemblie alignment inefficiency, and missing inspection easily occurs, these problems seriously hinder the automated production manufacture of laminated batteries.Electrode assemblie alignment detection device can replace manual detection to improve efficiency, and detection method is simple.
Summary of the invention
It is an object of the invention to provide a kind of electrode assemblie alignment detection device and detection method thereof, by detection infrared signal, reach the purpose of detecting electrode component alignment, this detection method simple and fast, detection efficiency can be effectively improved.
For achieving the above object, present invention employs techniques below scheme:
A kind of electrode assemblie alignment detection device, including electrode assemblie placement unit, carriage and infrared detecting device, described electrode assemblie placement unit is for placing and fixed electrode assembly, described carriage includes the slide mechanism being connected with described electrode assemblie and for the driver element driving slide mechanism to move, described infrared detecting device includes the infrared emission unit for launching infrared signal and the infrared detection unit by infrared emission unit detecting electrode assembly whether marshalling, and described electrode assemblie placement unit can pass through infrared signal.
The detection method of a kind of electrode assemblie alignment detection device, comprises the following steps:
(1) electrode assemblie is positioned in electrode assemblie placement unit；
(2) slide mechanism drives electrode assemblie placement unit to arrive and specifies position, and slide mechanism stops sliding；
(3) infrared emission unit launches infrared signal by setting procedure, infrared detection unit detects infrared signal automatically: if electrode assemblie is unjustified, then infrared signal can not pass through electrode assemblie placement unit, and detection device can not detect complete infrared signal, send alarm signal.
As shown from the above technical solution, electrode assemblie alignment detection device of the present invention and detection method thereof, the infrared signal launched by detection infrared launcher judges electrode assemblie whether marshalling, if infrared detecting device fails complete infrared signal to be detected, then can automatic alarm, the detection method simple and fast of this electrode assemblie alignment, can be effectively improved the detection efficiency of electrode assemblie.
