Referring to fig. 1, the present disclosure provides a lamination apparatus 10 and a lamination station 100. The lamination apparatus 10 includes a lamination station 100, a first feeding device 200, a second feeding device 300, and a lamination robot (not shown).
The pole pieces and diaphragms can be stacked on a lamination station 100 to make a cell. The first feeding device 200 is used for providing a first pole piece 11; the second feeding device 300 is used for providing the lamination unit 12, and the lamination unit 12 includes a second pole piece and a diaphragm attached to both sides of the second pole piece. One of the first pole piece 11 and the second pole piece is a negative pole piece, and the other is a positive pole piece. Specifically, in this embodiment, the first pole piece 11 is a positive pole piece, and the second pole piece is a negative pole piece. The lamination manipulator is used for alternately stacking the first pole pieces 11 and the lamination units 12 on the lamination table 100, so that the preparation of the battery cell is realized.
In this embodiment, the lamination device 10 further includes a detection device (not shown), which includes a light source (not shown) and a camera (not shown). The light source can send out and detect the light, and the camera can be to the image information of pole piece and diaphragm on the loading face to can detect the pile-up process on the loading face, realize the control to precision and yield.
Referring to fig. 2 and 3, a lamination stage 100 according to an embodiment of the present invention includes a carrier stage 110 and a pressing mechanism 120.
The susceptor 110 is generally a plate-shaped structure formed of a material having high mechanical strength, such as metal, and may have a rectangular shape. The bearing table 110 has a bearing surface, and the pole piece and the diaphragm for preparing the battery cell are both borne on the bearing surface. Specifically, in the process of preparing the battery core, the lamination manipulator alternately stacks the first pole piece 11 and the lamination unit 12 on the carrying surface of the carrying table 110.
In this embodiment, the lamination table 100 further includes a lifting mechanism 130, and the carrier table 110 is mounted at a driving end of the lifting mechanism 130 and can move in a direction perpendicular to the bearing surface under the driving of the lifting mechanism 130. Specifically, the lifting mechanism 130 may adopt a structure such as an air cylinder, a motor threaded screw pair, etc., and the height of the bearing platform 110 can be adjusted, so that the lifting mechanism is suitable for different production scenarios.
In addition, in the embodiment, the supporting platform 110 is provided with a heating assembly (not shown), and the heating assembly can heat the pole piece and the diaphragm supported on the supporting surface. Specifically, the heating elements, such as an electrical heating tube and a resistor, may be embedded in the susceptor 110, and may be heated by various methods, such as infrared heating, electromagnetic heating, or resistance heating.
Therefore, the cell starts to be heated in the manufacturing process, and the temperature of the cell is increased to be higher before the cell is subjected to hot pressing operation. Therefore, heat can be more rapidly transferred to the middle portion of the cell, so that heating is more rapidly and uniformly performed. When hot pressing operation is carried out, the temperature of the middle part of the battery core can reach the required temperature more quickly, so that the time required by the hot pressing operation is greatly shortened, and the production efficiency of the lithium battery can be obviously improved.
The pressing mechanism 120 includes a pressing driver 121 and a pressing blade 122, and the pressing blade 122 is mounted at the driving end of the pressing driver 121. The pressing driving member 121 can drive the pressing blade 122 to operate, so that the pressing mechanism 120 can be switched between a pressing state and an avoiding state. Specifically, the pressing driving member 121 can drive the pressing blade 122 to move horizontally and lift relative to the bearing surface, and can also drive the pressing blade 122 to turn over, so as to realize state switching.
When the pressing mechanism 120 is in a pressing state, the pressing blade 122 can press the pole piece and the diaphragm on the bearing surface. Therefore, the phenomenon that the stacked pole pieces and diaphragms are loosened or offset can be avoided. When the pressing mechanism 120 is in the avoiding state, the pressing blade 122 forms an avoiding position on the bearing surface. At this moment, the lamination manipulator can realize the normal placement of first pole piece and lamination unit.
Further, the pressing blade 122 can transmit light. The pressing blade 122 may be molded of a transparent material such as glass, resin, or the like, thereby achieving light transmission. Therefore, when the pressing blade 122 presses the pole piece and the diaphragm on the bearing surface, the pressing blade 122 does not block the view of the camera for photographing identification. The detection light emitted by the light source can pass through the pressing knife 122 and irradiate the pole piece and the diaphragm pressed on the bearing surface, so that the camera can smoothly acquire the image information of the pole piece and the diaphragm pressed on the bearing surface. Therefore, positioning failure of the pole pieces due to the pressing action of the pressing knife 122 can be avoided, and the lamination precision can be effectively improved.
In order to avoid the light from penetrating through the pressing blade 122 to be refracted, thereby affecting the positioning accuracy of the camera, the thickness of the pressing blade 122 is small, and the surface is flat, so that the refraction degree of the light can be reduced as much as possible.
In this embodiment, the lamination table 100 is provided with at least two bearing tables 110, and the driving end of the pressing driving member 121 is provided with a plurality of sets of pressing knives 122 corresponding to the at least two bearing tables 110 one by one.
Each set of blades 122 includes a plurality of, e.g., two, blades 122. Moreover, two pressing mechanisms 120 are provided in the embodiment, and the two pressing mechanisms are respectively located at two ends of the bearing platform 110. Thus, there are four pressing blades 122 for each carrier stage 110. When the pressing mechanism 120 is switched to the pressing state, the four pressing knives 122 can simultaneously press the corresponding pole pieces and diaphragms on the bearing table 110.
Further, in this embodiment, the lamination robot can simultaneously grab a plurality of first pole pieces 11 or a plurality of lamination units 12, and can stack the plurality of first pole pieces 11 or the plurality of lamination units 12 on the plurality of bearing tables 110, respectively. Therefore, the lamination device 10 can stack multiple groups of battery cells at the same time, so that the production efficiency is remarkably improved.

The first feeding device 200 can realize the real-time preparation of the first pole piece 11, and the cut first pole piece 11 can be sequentially grabbed by the lamination manipulator.
In the embodiment, the second feeding device 300 includes a second unwinding mechanism 310, a second slicing mechanism 320, two membrane unwinding mechanisms 330, a combining mechanism 340, and a cutting mechanism 350.
The second unwinding mechanism 310 is configured to unwind the second pole piece material strap 14, the second slicing mechanism 320 is configured to sequentially cut the second pole piece material strap 14 into a plurality of second pole pieces, and the second pole pieces cut by the second slicing mechanism 320 can sequentially enter the combining mechanism 340. The two membrane unwinding mechanisms 330 are used for unwinding the membrane material belts 15 on two sides of the second pole piece, and the membrane material belts 15 on the two sides can enter the compound mechanism 340 together with the second pole piece. The laminating mechanism 340 is capable of laminating the membrane web 15 with a second pole piece to produce the composite web 16. The composite mechanism 340 may employ two oppositely disposed press rollers, and the surfaces of the press rollers can generate heat to realize the hot-press composite.
In order to prevent the membrane from warping in the lamination process, thereby causing short circuit and other faults, the two layers of membranes of the lamination unit 12 can be subjected to edge sealing to form a pole piece bag structure.
Specifically, in this embodiment, the second feeding device 300 further includes an edge sealing mechanism 360 disposed between the cutting mechanism 350 and the combining mechanism 340, the composite material tape 16 can pass through the edge sealing mechanism 360, and the edge sealing mechanism 360 can attach the edges of the two layers of membrane material tapes 15 in the width direction.
The width of the strip of membrane material 15, i.e. the width of the strip of composite material 16, is in particular perpendicular to the plane of the drawing as shown in fig. 1. The composite strip 16 output from the compounding mechanism 340 is edge banded by an edge banding device 360 before being cut by the cutting mechanism 350. The edge banding mechanism may heat press the widthwise edges of the composite strip of material 16 to bond the edges of the two layers of membrane strip of material 16 together. When the cutting mechanism 350 cuts, the composite strip 16 is cut along the area between two adjacent second pole pieces, so that the two ends of the resulting lamination unit 12 form sealed edges.
In addition, referring to fig. 4, in another embodiment, the cutting mechanism 350 includes a pressing component 351 and a cutting component 352, the pressing component 351 forms a pressing surface, the cutting component 352 includes a base 3521 and a cutter 3522, the base 3521 forms a supporting surface opposite to the pressing surface, the cutting component 352 and the pressing component 351 can move relatively to clamp the composite tape 16 between the pressing surface and the supporting surface, and the cutter 3522 cuts off a portion of the composite tape 16 clamped between the pressing surface and the supporting surface, at least one of the pressing surface and the supporting surface can heat the composite tape 16 to heat cut openings at two sides of the cut portion of the composite tape 16.
The composite strip 16 is then passed between the pressing surface and the abutting surface, and the pressing element 351 and the cutting element 352 are moved toward each other, so that the composite strip 16 is clamped and cut. The cutter 3522 may be a hot cutter or a heat plate, and may be cut by heat-melting the separator material tape 15. Since the cut portion of the composite tape 16 is clamped between the pressing surface and the abutting surface, the cut openings on both sides of the cut portion are also clamped between the pressing surface and the abutting surface.
Further, at least one of the pressing surface and the abutting surface generates heat, the diaphragm of the fracture can be melted, hot-pressing edge sealing is realized on the fracture under the compression of the pressing surface and the abutting surface, two layers of diaphragms at the fracture are compounded, and edge sealing of the lamination unit 12 is realized.
Moreover, the heat sealing of the cutting opening and the cutting of the composite material tape 16 are almost simultaneously performed, and in the continuous cutting process of the cutting mechanism 350, both ends of the obtained lamination unit 12 are automatically heat sealed, so that the efficiency is not reduced due to the additional increase of the process on the premise of improving the quality of the battery cell.
In the lamination table 100 and the lamination apparatus 10, the pressing mechanism 120 can be switched between the pressing state and the avoiding state during the process of alternately stacking the first pole piece 11 and the lamination unit 12 on the bearing surface by the lamination robot. When the pressing mechanism 120 is switched to the pressing state, the pressing blade 122 presses the pole piece and the diaphragm on the bearing surface. Since the pressing blade 122 can transmit light, the view of the camera for photographing recognition is not blocked. Therefore, positioning failure of the pole pieces due to the pressing action of the pressing knife 122 can be avoided, and the lamination precision can be effectively improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
