Description
Technical field
The utility model relates to the device of a kind of on-line measurement pole piece length and degree of registration.
Background technology
Advantages such as lithium ion battery has voltage height, specific energy height, recycles often, memory time is long, not only on portable electric appts, be used widely as mobile phone, DV and laptop computer, and be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore more and more higher to the performance requirement of lithium ion battery.Electrode plates is the important component part of lithium ion battery, is important link in the lithium ion battery production process, is the core of lithium ion battery.The come out performance of quality decision lithium ion battery of pole piece of coating, such as self discharge height, quality problems such as cycle life is short, memory time is short, voltage is low, therefore the pole piece that comes out of coating needs strict control pole piece length and degree of registration.
At present in the pole piece testing process, adopt and manually pole piece is carried out the measurement of length, degree of registration, not only pole piece has been caused pollution in the measuring process, and measurement also might be inaccurate, causes in batches defective, and some pole piece length is long, can not on equipment, directly measure, pole piece need be taken off, measure on the ground, cause material and time waste, therefore a kind of on-line automatic measuring system is just very necessary.
The utility model content
The utility model is in order to overcome weak point of the prior art, and a kind of length and linearity that can the on-line measurement pole piece be provided, and prevents the harmful effect that manual measurement produces, and improves the on-line measurement pole piece length of pole piece quality and the device of degree of registration.
The utility model is achieved through the following technical solutions:
The device of a kind of on-line measurement pole piece length and degree of registration, it is characterized in that, on pole piece along being separately installed with top measuring light electric transducer on the horizontal same straight line, with the corresponding position of measuring light electric transducer, top bottom measuring light electric transducer is installed below the described pole piece, described top measuring light electric transducer is connected with the measuring-signal input of PLC controller by the signal amplifier module respectively with the signal input part of described bottom measuring light electric transducer, on the coating machine initiative drive shaft encoder is installed, the output of described encoder is connected with the code signal input of described PLC controller, and the data output end of described PLC controller is connected with display.
The utlity model has following technique effect:
1, length and the linearity that the device of pole piece length of the present utility model and degree of registration can the on-line measurement pole piece prevents the harmful effect that manual measurement produces, and improves the pole piece quality, avoids causing waste of material, and the production efficiency height helps reducing production costs.
2, adopt photoelectric device to improve measuring stability in the process.
3, photoelectric sensor connects signal amplifier, makes that the signal of sensor output is effective fast.
4, adopt high-precision encoder, coding counting precision height, error is little.
5, Shu Chu signal shows by display screen, is easy to the tester and observes.
Description of drawings
Fig. 1 is the schematic representation of apparatus of the utility model on-line measurement pole piece length and degree of registration.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 is the schematic representation of apparatus of the utility model on-line measurement pole piece length and degree of registration, above the pole piece 9 between anti-skidding rubber roll 8 and pole piece guide roller 7 along being separately installed with top measuring light electric transducer 6 on the horizontal same straight line, with the corresponding position of measuring light electric transducer, top bottom measuring light electric transducer 5 is installed below the described pole piece 9, described top measuring light electric transducer 6 is connected with the measuring-signal input of PLC controller 2 by signal amplifier module 3 respectively with the signal input part of described bottom measuring light electric transducer 5, encoder 4 is installed on the coating machine initiative drive shaft, the output of described encoder 4 is connected with the code signal input of described PLC controller 2, and the data output end of described PLC controller 2 is connected with display 1.For the reliability of data, top measuring light electric transducer and bottom measuring light electric transducer are respectively three.
Top measuring light electric transducer 6 and bottom measuring light electric transducer 5 are installed in the pole piece upper and lower surface respectively, and the alignment of the photoelectric sensor of top and bottom.The signal of two sensor detections and the counting of encoder all are transferred in the PLC controller, calculate length, the degree of registration of pole piece by process computer, and showing, thereby the on-line measurement of realization size by length, the degree of registration of display with pole piece.
Basic principle: during the coating single face, it is ON that the original position of pole piece is provided with detection signal, in the register of PLC controller, be set at A, it is OFF that the end position of setting pole piece (corresponding original position at interval) is provided with detection signal, numerical value exists and is made as B in the register, deduct the A difference with B and be set at C, multiply by preset parameter with C and draw coating length.The measuring principle of degree of registration is, two photoelectric sensors are responded to pole piece simultaneously up and down when coating is two-sided, sense pole piece simultaneously or leave pole piece simultaneously when super-interval, and the time difference of two photoelectric sensors calculates the degree of registration difference through conversion.
