Description
Technical field
The present invention relates to technical field of lithium ion, more particularly to a kind of stack type lithium ion battery pole piece punching use
Auxiliary mould and method for die cutting.
Background technology
Stack type lithium ion battery must will meet the electrode of battery size under punching on entire volume electrode using dedicated tool
Come, electrode coated form is divided into continuous coating and is segmented two kinds of forms of coating.Now for how to improve segmentation coated form electrode
The invention that die cutting accuracy and product percent of pass are carried out.
Existing punching equipment is typically punched out to the electrode of segmentation coating using fixed length form, but due in coating process
The reasons such as the error that the error of generation, motor are produced, can all cause the pole-piece pole-ear strip after being punched or pole piece dew paper tinsel, drop
The punching qualification rate of low electrode.
The course of work of existing semiautomatic precision punching system is：
1. advanced forward by motor band moving electrode, photosensitive infrared sensor is sampled above electrode to electrode；
2. when the plain edge of segmented electrode is through photosensitive infrared sensor, sensor sends a signal to motor；
3. motor starts to calculate length of travel；
4. when length of travel reaches the driving fixed length of setting, punching working platform completes punching to electrode.
In the production process of traditional stack type lithium ion battery, the qualification rate for being punched operation is relatively low, increased and produces into
This.Draw punching dimension overproof occur and cause underproof to main reason is that punching is adopted by the observation and analysis to situation
Sample linkage design is unreasonable.The photosensitive infrared sensor receiving portion of sampling linkage receives electrode flatness shadow itself
Ring, it is impossible to give punching platform by correct signal transmission, cause punching platform stroke defect, cause pole piece qualification rate after punching
Low, waste of material is extremely serious.
It is to sample linkage to control the precision of punching by punching in existing punching system, the sampled point that the device is adopted
For photosensitive infrared sensor, its principle is that the light launched by photosensitive infrared sensor is reflected on electrode material and copper (aluminium) paper tinsel
Afterwards, the reflected value of reception is different starts counting up controlling motor, and this sampling apparatus is put down to the body surface being sampled
It is whole degree require it is higher, require in simple terms sampled point to the distance of electrode surface be fixed.The mode of segmentation coating is given birth to
The electrode of output is different from the elongation of matrix due to material, and after roller compaction processes are rolled, electrode surface flatness is poor, this
The numerical bias that the electrode of sample feeds back to photosensitive infrared sensor when by sampled point are too big, cause that lug occurs during punching
The phenomenon that strip is too high or pole piece dew paper tinsel is excessive.
The content of the invention
