Abstract
The utility model discloses a battery pole-piece wrapping quality test device. The test device takes use of the characteristic that different components of the battery pole-piece appears in different colors when exposed under X rays; the image of the electric core captured under the irradiation of an X-ray fluoroscopy device is transmitted into an image recognizer which compares the captured image and an ideal image to identify ineligible electric core; this will facilitate setting an automatic sorting-out device to pick out ineligible products or setting an alarm device to warn the operator to pick out the ineligible products so as to save the costs in the subsequent working procedures. The utility model improves the deficiency of prior art that the wrapping quality of battery pole-pieces can not be tested quickly and accurately.
Description
Technical field:
The utility model relates to a kind of device that detects the battery pole piece manufacturing quality
Background technology:
The positive pole of lithium ion is made up of LiCoO2 (cobalt acid lithium), conductive agent (acetylene black), bonding agent (PVDF), collector (aluminium foil), negative pole is made up of graphite, conductive agent (acetylene black), thickening agent (CMC), cementing agent (SBR), collector (Copper Foil), when positive and negative electrode constitutes electric core, need between positive pole and negative pole, add porous septum and be wound into column type or square, again above-mentioned film (positive pole, barrier film, barrier film) is inserted in the shell, reinject and seal behind the electrolytic solution, promptly obtain the battery finished product.Yet deviation appears in the diaphragm position during as if coiling between the positive and negative electrode, may cause positive and negative plate directly to contact, thereby the capacity of battery is descended significantly.In the existing manufacturing process, because pole piece and membrane coil be around the back multiple-level stack, whether the electrode after the workman can't artificial cognition reels exists short circuit, causes many unnecessary cost allowances.Because anodal, negative pole and diaphragm material difference, under the irradiation of X-ray, the color of the image that presents is also different, and the image of supposing anode is a black, and the color of barrier film is yellow, and the image of negative electrode is a grey, expects that then yellow isolates black and grey fully.Someone has designed a kind of battery pole piece manufacturing quality pick-up unit: X-ray machine is set, and X-ray machine links to each other with picture pick-up device, and the workman is according to the image that picture pick-up device obtains, judge battery to be checked whether roll operation qualified.But because the workman is in so simply repeating in the work, vision is tired easily, influences the accuracy of judged result, and in addition, the individual difference of workman's subjective judgement also can cause the unsatisfactory consequence of testing result.
The utility model content:
The purpose of this utility model provides a kind of battery pole piece manufacturing quality pick-up unit, and the accuracy rate of the technology of the manufacturing quality of the electric core of the existing detection of energy is avoided sequential loss better.
Battery pole piece manufacturing quality pick-up unit described in the utility model, comprise the X-ray machine of aiming at battery, X-ray machine links to each other with picture pick-up device, it is characterized in that: also be provided with the image recognition device that links to each other with picture pick-up device, the image input picture recognizer that picture pick-up device obtains.
Because positive pole, negative pole and diaphragm material difference, under the irradiation of X-ray, the color that presents is also different, and picture pick-up device can be differentiated the image input picture identification equipment of electric core under the X-ray irradiation automatically barrier film by the image recognition device and whether isolate positive and negative electrode fully.Wherein the image recognition device is a prior art, does not give unnecessary details at this.Utilize the utility model that alarm or electric core screening installation can conveniently be set, report to the police according to the result of image recognition device and abandon defective electric core by operator or operating equipment.The utility model can significantly improve recognition efficiency and accuracy rate, helps the producer to choose defective electric core better, avoids sequential loss.
Description of drawings:
Accompanying drawing is a synoptic diagram of the present utility model.
Embodiment:
X-ray machine is radiated on the electric core 5, and picture pick-up device 1 obtains the image behind the x-ray fluoroscopy, again the gained image is input to image recognition apparatus 2, and image recognition apparatus links to each other with alarm.The image of supposing anode is a black, the color of barrier film is yellow, the image of negative electrode is a grey, expect that then yellow isolates black and grey fully, if taken image does not meet anticipated conditions, image recognition apparatus notice alarm or electric core screening installation are abandoned the respective electrical core or are abandoned the respective electrical core by electric core screening installation by the operator.
In order to observe electric core from all angles, electric core is placed on the rotatable pedestal 4, on one side rotation, observe on one side, can obtain the electric core image of all angles, obtain result more accurately, the loss of further less subsequent technique.
