Specific embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
In Production Process of Lithium Battery, required foil raw material is generally aluminium foil or Copper Foil, and color is respectively silvery white And Chinese red, and slurry is mostly black.When slurry is coated on foil, the foil of slurry is scribbled in black, and uncoated The foil of slurry is silvery white in color or Chinese red, so, whether slurry is coated in the color difference correspondingly presented on foil, because This, can be known by the color for detecting foil and whether be coated with slurry on foil.
Above-mentioned Cleaning Principle is based on, the utility model provides a kind of detecting system, and the detecting system is used for detecting battery pole The color of piece, i.e. foil, and correspondingly controlled by the respective change of color.
The detecting system includes roll squeezer and detection means, as the roll squeezer is existing equipment, here no longer specifically Bright, below the detection means is described in detail.
The detection means includes color detection module, for detecting that foil applies the color of charge level, so, the color detection mould Block is the equipment for being capable of distinguishing colours difference, can be color sensor, or vision sensor, or other are existing Relevant device, such as camera, in the present embodiment, by taking vision sensor as an example.As vision sensor and color are sensed Device belongs to prior art, just no longer specifically describes here.
As the detecting system was detected before foil roll-in, so, vision sensor is arranged on roll squeezer and enters At material end.And due to when lithium battery is produced, being typically coated slurry to two faces of foil, correspondingly, the detection Device includes two groups of vision sensors, is provided with least one vision sensor, every group of visual sensing in every group of vision sensor Device is arranged on the side of feeding of roll squeezer foil, specially:One group of vision sensor is arranged on the upside of feeding of roll squeezer foil, Another group of vision sensor is arranged on the downside of feeding of roll squeezer foil, by so setting, can make every group of vision sensor The foil one of color that apply charge level is correspondingly detected.Each vision sensor in every group of vision sensor is towards corresponding Foil applies charge level, and on the basis of satisfaction can detect corresponding painting charge level, vision sensor can vertically apply charge level, Can incline towards painting charge level.
In the present embodiment, a vision sensor is provided with every group of vision sensor, then in the detection means altogether There are two vision sensors, as shown in Fig. 2 a upside for being arranged on feeding of roll squeezer foil, for detecting face of coating, separately One downside for being arranged on feeding of roll squeezer foil, for detecting lower painting charge level.In order to fix the two vision sensors, entering Material is provided with a fixed support at end, and vision sensor is separately fixed at the corresponding position on the support.Certainly, in order to carry High measurement accuracy, is also provided with multiple vision sensors in every group of vision sensor, every group of vision sensor distribution is arranged, Simultaneously the plurality of positions on same painting charge level is detected.
The detection means also includes control module, the colouring information for being detected according to vision sensor be analyzed and Judge.Control module is existing control chip, and such as single-chip microcomputer or PLC, in the present embodiment, by taking PLC as an example.
As shown in figure 3, PLC controls connection roll Medium-voltage Motor by hub sampling two vision sensors of connection.
In roll squeezer course of normal operation, with the rotation of roll squeezer, foil to be rolled enters in roll squeezer Row roll-in.Two vision sensors correspondingly detect two painting charge levels of the foil to be rolled of process in real time.The two visions are passed Sensor exports the colouring information of the corresponding painting charge level of real-time detection to PLC, and PLC is write in advance according to colouring information and according to inside Good software program is analyzed and judges.Color due to being coated with slurry and uncoated slurry is inconsistent, and PLC is according to color Difference be made whether the judgement for being coated with slurry, when one of charge level that applies the situation of uncoated slurry occurs or when two When applying the situation that uncoated slurry occurs in charge level, PLC control roll squeezers quit work, that is, control roll-in motor stalls, The foil circulation of uncoated slurry is avoided to subsequent processing.When multiple vision sensors are provided with every group of vision sensor, In order to improve judgement precision, for one group of sensor, as long as wherein there is a sensor to detect the situation for not coating coating When, PLC just controls roll squeezer shutdown.
So, the detection means can realize the whether two-sided detection for being coated with slurry of electrodes of lithium-ion batteries.By this The device of sample, can in nipping process the uncoated slurry of any one side of not roll-in pole piece.
In above-described embodiment, as two faces on foil scribble slurry, then, detection means includes that two groups of visions are passed Sensor, per group of painting charge level for being used for correspondingly detection foil.This is a kind of specific embodiment, used as other enforcements Mode, if scribble slurry on only one of which face on foil, then, detection means can only include one group of vision sensor, court To the side for scribbling slurry, when the situation of uncoated slurry occurs in the face, PLC control roll squeezers are shut down.
Specific embodiment is presented above, but the utility model is not limited to described embodiment.This practicality New basic ideas are above-mentioned basic scheme, for those of ordinary skill in the art, according to teaching of the present utility model, Design the model of various modifications, formula, parameter and creative work need not be spent.Without departing from principle of the present utility model Protection domain of the present utility model is still fallen within the change, modification, replacement and modification embodiment carried out in the case of spirit Interior.
