Embodiment Construction

[0027] As shown in the figure, the online detection and sorting system for surface defects of lithium battery pole pieces includes:

[0028] The pole piece conveying device, after passing the pole piece uninterruptedly through the detection area of ​​the pole piece detection device for detection, then sends the pole piece to the sorting area of ​​the pole piece sorting device;

[0029] The pole piece identification and detection device includes an upper collection and detection device and a lower collection and detection device that simultaneously identify the front and back sides of the pole piece. Below, real-time acquisition, analysis and processing of the front and back images of the pole piece, and the processing results are sent to the main control unit of the pole piece;

[0030] The pole piece main control unit is used to realize the control of the pole piece conveying device, the acquisition of the processing result of the pole piece identification and detection devic...

Abstract

The invention discloses an on-line lithium battery pole piece surface defect detection sorting system and method. The synchronous real-time on-line detection on positive and reverse sides of pole pieces is realized through a pole piece conveying device, a pole piece identification and detection part, a pole piece master control unit, a pole piece sorting device and a human machine interface part; a mechanical structure of the system is simple, the detection on the positive and reverse sides of the pole pieces can be realized in the system through a simple detection channel, and the system is simple, feasible and low in cost. The detection speed is high, the general detection speed is superior to 2 pieces per second, the detection precision is high, and an embedded visual identification detection technology adopted by the system has the high precision with the omission ratio of 0 and the error detection rate of less than 2 percent. According to the pole piece detection sorting device, the secondary damage of the pole pieces is avoided. The actionability is high, and the system is long in operating time, can operate for long time in the industrial field and has the advantages of convenience in maintenance, high portability and the like.

Description

technical field [0001] The invention relates to the field of online detection of surface defects of lithium battery pole pieces, in particular to an online detection and sorting method for surface defects of lithium battery pole pieces and a special sorting system thereof. Background technique [0002] With the advantages of zero pollution, zero emission, high energy density, small size and long cycle life, lithium batteries are widely used in portable electronic products, electric vehicles, large power supplies, secondary charging and energy storage, etc. The main body of the development and application of power batteries at home and abroad, so the quality of lithium batteries is particularly important. [0003] The electrode pole piece is the main body of the lithium battery, and the quality of the coated pole piece directly determines the quality of the lithium ion battery. Surface defects such as creases, missing prints, damage, and particles on the pole pieces lead to...
