Description
Technical field
The utility model relates to a kind of detection system, particularly relates to a kind of detection system of slurry coating width of electrodes of lithium-ion batteries.
Background technology
Lithium ion battery has the advantages such as voltage is high, specific energy is high, recycle often, storage time is long, not only on a portable electronic device as mobile phone, Digital Video and laptop computer are used widely, and be widely used in the big-and-middle-sized electrical equipments such as electric automobile, electric bicycle and electric tool, therefore more and more higher to the safety requirements of lithium ion battery.
In lithium ion battery production run, need to make anode and cathode slurry, then slurry is coated on corresponding positive/negative plate.For the lithium ion battery of different model, also different to the regulation of the coating width of slurry, the coating width that demand fulfillment specifies, to manufacture the battery of regulatory specifications, detects coating width in the coating procedure therefore needed.
But, at present, in coating procedure, unique detection method carries out manual measurement, and the method measuring error is large, and easily touch pole piece and make pole piece damaged, effectively cannot carry out the measurement of pole piece application width, be difficult to control application width, produce defect ware sometimes.In addition, slurry or follow-up waste can also be caused application width is wide or narrow.
Summary of the invention
The utility model proposes for problems of the prior art, its object is to provide a kind of can the detection system of slurry coating width of the high electrodes of lithium-ion batteries of the kinetic measurement pole piece coating width precision carrying out in real time monitoring.
Following technical scheme is adopted for realizing the purpose of this utility model.
The detection system of the slurry coating width of the electrodes of lithium-ion batteries of technical scheme 1, comprise CCD camera, image processing system and Programmable Logic Controller, described CCD camera has 2, be arranged in the horizontal rail vertical with pole piece throughput direction respectively, take the base material edge of pole piece and slurry coating edge, described CCD camera, described image processing system and described Programmable Logic Controller are interconnected by hub.
The detection system of the slurry coating width of the electrodes of lithium-ion batteries of technical scheme 2, in the detection system of the slurry coating width of the electrodes of lithium-ion batteries of technical scheme 1, described Programmable Logic Controller is connected with described alarm.
Compared with prior art, the utility model has following beneficial effect.
According to the detection system of the slurry coating width of the electrodes of lithium-ion batteries of technical scheme 1, have the edge CCD camera of taking on the Width of the pole piece of coating, and image processing system and Programmable Logic Controller.Thus, coating edge image can be collected by CCD digital camera, its digital output signal can pass image processing system, disposal system identifies pole piece base material edge and slurry coating edge by the mode such as image conversion and binaryzation, calculate distance d1, the d2 between pole piece base material edge in the direction of the width and slurry coating edge, then being d0 according to base material overall width, coating width d=d0-d1-d2 is calculated.Such coating width data send to Programmable Logic Controller (PLC), undertaken judging and controlling, realize the detection to coating width by PLC.By such device, in coating procedure, can carry out dynamic autoization monitoring to pole piece volume application width, Measurement sensibility, precision is high.
In addition, according to the detection system of the slurry coating width of the electrodes of lithium-ion batteries of technical scheme 2, Programmable Logic Controller is also connected with alarm, thus when detecting that coating width exists deviation, can report to the police to operating personnel, reminds and occurs extremely.
