As shown in fig. 1-2, an embodiment of the present application provides a method for producing tablets, including:
the roller drives the belt material to move to the cutting station along with the roller surface;
the laser device performs cutting operation on the strip material at the cutting station to form a pole piece;
The roller drives the pole piece to move to a blanking station along with the roller surface;
the roll 1 has a roll surface (may be hexahedral or circular arc, and the roll surface may be an inner circumferential surface of the roll or an outer circumferential surface of the roll, depending on a specific structure of the roll), and is capable of fixing the band and the pole piece on the roll surface, specifically, a negative pressure adsorption area 121 is provided on the roll surface, and the negative pressure adsorption area 121 includes a plurality of vacuum holes distributed in an array, and the band and the pole piece are adsorbed and fixed in the negative pressure adsorption area through the vacuum holes. Moreover, roller 1 can rotate along circumference to drive area material and pole piece along with the roll surface along circumference displacement, and then drive area material and pass through cutting station, and drive the pole piece and pass through the unloading station, in order to accomplish and cut and unloading process, need not to transport through the vacuum belt, make area material and pole piece carry and transport shared space less, be favorable to reduce cost, because area material and pole piece are along with the roll surface displacement, can not produce the phenomenon of skidding, be favorable to carrying out accurate location to the pole piece.
It should be noted that, after the roller 1 drives the strip material to pass through the cutting station and cut to form the pole piece, the roller 1 drives the cut pole piece to move from the cutting station to the blanking station, here, the cutting station and the blanking station are not limited to be two stations in close proximity, in the scheme, other stations can be further arranged between the cutting station and the blanking station, and only the roller 1 can drive the pole piece to move from the cutting station to the blanking station. In addition, the roller can drive the belt material and the pole piece to move along the roller surface, and the belt material is formed into the pole piece after moving to the cutting station along the roller surface, namely the belt material is adsorbed on the roller surface and in the area before the cutting station, and the belt material and the pole piece are adsorbed in the area after the cutting station on the roller surface.
The laser device 4 is configured to emit laser light and perform cutting operation of the tape at the cutting station by the laser light, and specifically, the laser device 4 is provided in a space region on the outer peripheral side or the inner peripheral side of the roller 1 and has a laser head, and cutting operation of the tape is performed by displacement of the laser head.
The blanking device 7 receives the pole piece at the blanking station.
When the roller 1 drives the pole piece to rotate to the blanking station, the roller 1 enables the pole piece to be separated from a negative pressure adsorption area 121 on the roller 1 (specifically, positive pressure can be introduced into the negative pressure adsorption area 121 to push the pole piece to be separated from the negative pressure adsorption area 121), and then the pole piece falls onto the blanking device 7, so that the blanking device 7 can receive the pole piece.
Like this, decide station and unloading station and all form in the periphery or the inner periphery of roller 1 to arrange along the direction of rotation of roller 1, so that the pole piece after deciding the station and cutting can be through the rotation of roller 1, transport to the unloading station, and carry out the unloading operation at the unloading station, be favorable to promoting the work efficiency of film-making flow.
In some schemes, the blanking device performs deviation rectifying operation on the received pole piece. The blanking device 7 carries out deviation rectifying operation on the received pole piece so that the position and angle of the pole piece meet the conditions required by the subsequent lamination process, and therefore the blanking device is convenient for directly carrying out lamination operation on the pole piece after blanking and is beneficial to improving the efficiency of battery cell preparation. So, can accept the pole piece after cutting out through unloader 7 to carry out the operation of rectifying to the pole piece after accepting, so that directly carry out the lamination operation to the pole piece after the unloading, be favorable to promoting the efficiency of electric core preparation, need not to carry out the operation of rectifying to the pole piece on roller 1 moreover, can simplify the structure of roller 1 greatly, promote the reliability of roller 1.
After the blanking device performs deviation rectifying operation on the received pole piece, the lamination device performs lamination operation on the pole piece after deviation rectifying, and then pole piece flaking and battery cell lamination are integrated together, so that the pole piece transportation process is reduced, and the working efficiency is improved. Specifically, a lamination device is arranged at the downstream of the blanking device, and after the pole pieces are rectified through the blanking device, the pole pieces are conveyed to a lamination table of the lamination device, and then lamination operation is carried out on the pole pieces through the lamination device.
Of course, in some other schemes, the blanking device is a stacking table of the stacking device, after the pole pieces are transferred to the stacking table by the roller, the stacking device directly performs stacking operation on the received pole pieces, so that the pole pieces complete stacking of the pole pieces while blanking, and then the battery cell embryonic form is formed between the stacked pole pieces through the diaphragm. Further simplifying the process of pole piece making and cell lamination. Specifically, the correction of the pole piece can be integrated on the roller, and the pole piece can be laminated without correction through the design of parameters, for example, the diameter of the roller is large enough, the width of the pole piece is small enough, the pole piece is close to a plane state on the roller surface of the roller, the distance between the blanking device and the roller is small enough, so that the offset generated during blanking of the pole piece can be ignored, and the pole piece can meet lamination conditions after blanking.
Further, the present tableting method comprises:
the roller 1 drives the belt material to pass through a cutting station and cut into pole pieces, and then drives the pole pieces to pass through a detection station, a blanking station and a reject station in sequence;
wherein, decide station, detection station, unloading station and rejection station set gradually along the axial of roller 1 to make roller 1 rotate and can drive the area material and pass through the station of deciding, with deciding and form the pole piece, can drive the pole piece after cutting again and pass through detection station, unloading station and rejection station in proper order, here, detection station is located the upper reaches of unloading station and rejection station, so that select separately the pole piece after deciding through the detection, with rejecting unqualified pole piece.
The detection device 6 detects the pole piece at the detection station to judge whether the pole piece is qualified or not;
wherein the detection operation comprises at least a size detection and a defect detection of the pole pieces so that the pole pieces meet the conditions required for lamination, in particular the detection means 6 may be provided as a CCD line scanning device. The detection device 6 may send the detection result to the controller, and the controller may determine whether the pole piece is acceptable, and the detection device 6 may be provided with a controller that determines whether the pole piece is acceptable.
The blanking device 7 receives qualified pole pieces which are positioned at the blanking station;
the reject device 8 receives unqualified pole pieces at the reject station.
When the roller 1 drives the pole piece to rotate to the reject station, the roller 1 makes the pole piece separate from the negative pressure adsorption area 121 on the roller surface (specifically, positive pressure can be introduced into the negative pressure adsorption area 121 to push the pole piece to separate from the negative pressure adsorption area 121), and then the pole piece falls onto the reject device 8, so that the reject device 8 receives the pole piece.
In the flaking process, under the drive of the roller 1, the cut pole piece is transported to a detection station, and the pole piece is detected by a detection device 6 to judge whether the pole piece is qualified (namely, whether the condition required by the subsequent lamination process is met), if the pole piece is qualified, the pole piece is transported to a blanking station, is carried out through the blanking device 7, is further transported to a lamination system, and if the pole piece is unqualified, the pole piece is transported to a reject station, and is carried through a reject device 8.
Therefore, under the action of the detection device 6, the cut pole piece can be detected to remove unqualified pole pieces and reserve qualified pole pieces, so that the quality of the battery cells formed by subsequent lamination is improved.
In some embodiments, the present tableting method comprises:
the laser device 4 is provided with a plurality of strips, and the strips at the cutting station are respectively cut to form a plurality of pole pieces;
wherein, laser device 4 can set up to 2 or n, cuts the area material simultaneously through a plurality of laser devices 4 to form a plurality of pole pieces respectively, can promote the efficiency that the pole piece was decided. It will be appreciated that the strip forming the plurality of pole pieces may be received simultaneously at the cutting station for cutting operations by the plurality of laser devices 4.
The roller drives the pole piece to sequentially pass through the detection station, the blanking station and the reject station;
the detection device 6 is provided with a plurality of detection devices, and respectively detects the plurality of pole pieces at the detection station to judge whether the plurality of pole pieces are qualified or not;
wherein, detection device 6 can set up to 2 or n, detects a plurality of pole pieces simultaneously through a plurality of detection device 6, can promote the efficiency that the pole piece detected. It will be appreciated that a plurality of pole pieces may be provided simultaneously at the inspection station for inspection operations by a plurality of inspection devices 6.
It should be noted that, the quantity of laser device 4 and detection device 6 keeps unanimous, and like this, a plurality of laser devices 4 cut out the station to a plurality of pole pieces back, and a plurality of pole pieces flow into the detection station simultaneously, and a plurality of detection device 6 of rethread detects a plurality of pole pieces, and then realizes the film-making of batch, is favorable to promoting film-making efficiency.
If the pole pieces are qualified, the blanking device 7 receives the pole pieces at the blanking station;
otherwise, the reject device 8 receives a plurality of pole pieces at a reject station.
Wherein, because a plurality of pole pieces pass through cutting station, detection station, unloading station and rejection station in proper order in batches, after cutting and detecting through cutting device and detection device 6, still need unloader 7 to carry out the unloading to a plurality of pole pieces to and reject device 8 to a plurality of pole pieces, at this moment, in order to avoid unqualified product to enter into follow-up lamination process, have any one unqualified in a plurality of pole pieces all to need to carry out the operation of rejecting through rejecting device 8 to make a plurality of pole pieces that enter into unloader 7 all qualified.
Like this, a plurality of pole pieces pass through cutting station, detection station, unloading station and rejection station in proper order in batches to cut, detect, unloading and rejection in proper order, can promote the cutting efficiency of pole piece greatly, through the above-mentioned sorting mode of detection device 6 simultaneously, can promote the product quality of follow-up lamination.
In other embodiments, based on the above scheme, the difference is that: when any one of the plurality of pole pieces is qualified, the blanking device receives the qualified pole piece which is positioned at the blanking station; when any one of the plurality of pole pieces is unqualified, the reject device receives the unqualified pole piece at the reject station.
In the working process, the positions of the qualified pole pieces and the unqualified pole pieces can be marked through the detection device, the states (whether the pole pieces are qualified or not) of the pole pieces in the blanking station can be obtained through position judgment, then the qualified pole pieces are screened at the blanking station and blanking is carried out on the qualified pole pieces, correspondingly, the states of the pole pieces of the reject station can also be obtained, and then the unqualified pole pieces are screened at the reject station and blanking is carried out on the unqualified pole pieces. Therefore, the sorting process of the waste removing device can be omitted, and the structure is simplified.
Further, after the above-mentioned rejecting device 8 receives a plurality of pole pieces at a rejecting station, it includes:
the first vacuum belt 81 receives and conveys a plurality of pole pieces at the reject station;
if the pole piece is not qualified, the first vacuum belt 81 conveys the pole piece to the reject cavity 83;
