[0052] The present application provides a laminator 100. Refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of the laminator provided by the present application. Figure 2 is Figure 1 a reference numeral schematic diagram of the laminator.

[0053] The laminator 100 includes a lamination device 101. The lamination device 101 includes a first transportation mechanism 10, a second transportation mechanism 20, a first lamination assembly 30, a second lamination assembly 40, a first handling assembly 50, and a second handling assembly 60.

[0054] Among them, the first transport mechanism 10 and the second transport mechanism 20 are respectively used to transport the first pole piece and the second pole piece along the first horizontal direction, and are arranged at intervals from each other along the second horizontal direction perpendicular to the first horizontal direction. The first lamination assembly 30 and the second lamination assembly 40 are respectively arranged at intervals along the second horizontal direction, and the first lamination assembly 30 is located on one side of the first transport mechanism 10 away from the second transport mechanism 20, and the second lamination assembly 40 is located on one side of the second transport mechanism 20 away from the first transport mechanism 10. The first handling assembly 50 and the second handling assembly 60 are arranged above the first transport mechanism 10 and the second transport mechanism 20 and are spaced from each other along the first horizontal direction, and the first handling assembly 50 and the second handling assembly 60 are respectively located on opposite sides of the first lamination assembly 30 and the second lamination assembly 40.

[0055] The first handling assembly 50 is used to handle the first pole piece from the first transport mechanism 10 to the first lamination assembly 30 and the second lamination assembly 40, and the second handling assembly 60 is used to handle the second pole piece from the second transport mechanism 20 to the first lamination assembly 30 and the second lamination assembly 40. Both the first lamination assembly 30 and the second lamination assembly 40 are used to laminate the first pole piece, the second pole piece and the separator into an electric core.

[0056] Among them, the first pole piece is an anode piece and the second pole piece is a cathode piece; or the first pole piece is a cathode piece and the second pole piece is an anode piece.

[0057] The first handling assembly 50 and the second handling assembly 60 cooperate and handle simultaneously, and continuously handle the first pole piece and the second pole piece from the first transport mechanism 10 and the second transport mechanism 20 to the first lamination assembly 30 and the second lamination assembly 40, which is beneficial to improving the lamination efficiency of the laminator 100.

[0058] In one embodiment, in a group of lamination devices 101, at least one group of "the first lamination assembly 30, the second lamination assembly 40, the first handling assembly 50 and the second handling assembly 60" is arranged on the transport lines of the first transport mechanism 10 and the second transport mechanism 20. Multiple groups of "the first lamination assembly 30, the second lamination assembly 40, the first handling assembly 50 and the second handling assembly 60" are arranged along the first transport mechanism 10 and the second transport mechanism 20, which is further beneficial to improving the lamination efficiency of the laminator 100.

[0059] In another embodiment, the laminator 100 includes at least one set of lamination devices 101. The lamination devices 101 are all arranged along the transportation line in the first horizontal direction. The transportation lines of adjacent first transportation mechanisms 10 are communicated with each other, and the transportation lines of adjacent second transportation mechanisms 20 are communicated with each other. That is, multiple sets of first transportation mechanisms 10 are arranged front and back along the transportation line. The previous first transportation mechanism 10 can convey the first pole piece to the next first transportation mechanism 10. The conveying speed of the first transportation mechanism 10 is adjusted automatically so that the first pole piece conveyed thereon is aligned with the first lamination assembly 30 and the second lamination assembly 40 when being picked up by the first handling assembly 50, which is beneficial to improving the picking efficiency.

[0060] In this embodiment, the laminator 100 includes two sets of lamination devices 101. The two sets of lamination devices 101 are both arranged along the transportation line in the first horizontal direction. Adjacent two first transportation mechanisms 10 convey the first pole piece. A part of the first pole pieces are consumed and used by the previous set of lamination devices 101, and another part of the first pole pieces are consumed and used by the next set of lamination devices 101. Adjacent two second transportation mechanisms 20 convey the second pole piece. Similarly, a part of the second pole pieces are consumed and used by the previous set of lamination devices 101, and another part of the second pole pieces are consumed and used by the next set of lamination devices 101.

[0061] In the embodiment of the present application, by adopting the first transportation mechanism 10 and the second transportation mechanism 20 to convey the first pole piece and the second pole piece respectively, it is possible to avoid confusing the first pole piece and the second pole piece during the conveying process. And by respectively arranging the first lamination assembly 30 and the second lamination assembly 40 on both sides of the transportation lines of the first transportation mechanism 10 and the second transportation mechanism 20, and respectively arranging the first handling assembly 50 and the second handling assembly 60 on both sides of the first lamination assembly 30 and the second lamination assembly 40, and the first handling assembly 50 continuously transports the first pole piece from the first transportation mechanism 10 to the first lamination assembly 30 and the second lamination assembly 40, and the second handling assembly 60 continuously transports the second pole piece from the second transportation mechanism 20 to the first lamination assembly 30 and the second lamination assembly 40, the lamination efficiency of the laminator 100 is improved, and the layout of each component is compact, and the overall floor space of the laminator 100 is small.

[0062] In this embodiment, both the first transportation mechanism 10 and the second transportation mechanism 20 include a conveying component and a negative pressure system. A plurality of adsorption holes are provided on the conveying component, and the negative pressure system is communicated with the adsorption holes. The negative pressure system adsorbs the corresponding pole piece through the adsorption holes, and the conveying component is used to convey the pole piece, and this pole piece can be the first pole piece or the second pole piece.

[0063] Specifically, the conveying component includes an adsorption platform and a conveyor belt. A plurality of adsorption holes are provided on the conveyor belt, and the conveyor belt conveys in the first horizontal direction along the adsorption platform. The negative pressure system is arranged inside the adsorption platform and communicated with the adsorption platform, so as to continuously adsorb the first pole piece and the second pole piece on the conveyor belt.

[0064] As Figure 2 shown, the first lamination assembly 30 includes a first pole piece positioning mechanism 31, a third pole piece positioning mechanism 32, a first lamination table 33, and a first separator unwinding assembly 34.

[0065] The second lamination assembly 40 includes a fourth pole piece positioning mechanism 41, a second pole piece positioning mechanism 42, a second lamination table 43, and a second separator unwinding assembly 44.

[0066] Among them, the first pole piece positioning mechanism 31 and the second pole piece positioning mechanism 42 are used to position and correct the deviation of the first pole piece to adjust the position of the first pole piece. The third pole piece positioning mechanism 32 and the fourth pole piece positioning mechanism 41 are used to position and correct the deviation of the second pole piece to adjust the position of the second pole piece. The first separator unwinding assembly 34 and the second separator unwinding assembly 44 are used to stack the separator between the first pole piece and the second pole piece. The first lamination table 33 and the second lamination table 43 are used to laminate the first pole piece, the second pole piece, and the separator into an electric core.

[0067] Among them, the positioning and deviation correction and lamination in the above process can be carried out synchronously, which is beneficial to improving the lamination efficiency of the laminator 100.

[0068] Furthermore, the lamination device 101 further includes a first pole piece buffer mechanism 45 and a second pole piece buffer mechanism 35. The first pole piece buffer mechanism 45 is arranged directly above the second transport mechanism 20 and between the first lamination assembly 30 and the second lamination assembly 40. The second pole piece buffer mechanism 35 is arranged directly above the first transport mechanism 10 and between the first lamination assembly 30 and the second lamination assembly 40, further saving the floor space of the laminator 100.

[0069] The first handling assembly 50 transports the first pole piece on the first transport mechanism 10 to the first pole piece positioning mechanism 31, and transports the first pole piece after positioning and deviation correction on the first pole piece positioning mechanism 31 to the first lamination table 33. Among them, the processes of transporting the first pole piece to the first pole piece positioning mechanism 31 and transporting the first pole piece to the first lamination table 33 are carried out synchronously, thereby improving the handling efficiency of transporting the first pole piece in the laminator 100, and thus being beneficial to improving the working efficiency of the laminator 100.

[0070] The first handling component 50 further transports the first pole piece on the first transport mechanism 10 to the first pole piece buffer mechanism 45, transports the first pole piece on the first pole piece buffer mechanism 45 to the second pole piece positioning mechanism 42, and transports the first pole piece after positioning and deviation correction on the second pole piece positioning mechanism 42 to the second lamination table 43. Among them, the processes of transporting the first pole piece to the first pole piece buffer mechanism 45, transporting the first pole piece to the second pole piece positioning mechanism 42, and transporting the first pole piece to the second lamination table 43 are carried out synchronously, thereby improving the handling efficiency of the first pole piece in the laminator 100, and thus being beneficial to improving the working efficiency of the laminator 100.

[0071] Specifically, as Figure 3 shown, the first handling component 50 includes a first picking mechanism 51, a second picking mechanism 52, a third picking mechanism 53, a fourth picking mechanism 54, and a fifth picking mechanism 55.

[0072] Refer to Figure 3 and Figure 4 , the first picking mechanism 51 is used to transport the first pole piece on the first pole piece positioning mechanism 31 to the first lamination table 33, the second picking mechanism 52 is used to transport the first pole piece on the first transport mechanism 10 to the first pole piece positioning mechanism 31, the third picking mechanism 53 is used to transport the first pole piece on the first transport mechanism 10 to the first pole piece buffer mechanism 45, the fourth picking mechanism 54 is used to transport the first pole piece on the first pole piece buffer mechanism 45 to the second pole piece positioning mechanism 42, and the fifth picking mechanism 55 is used to transport the first pole piece on the second pole piece positioning mechanism 42 to the second lamination table 43.

[0073] In this embodiment, the first picking mechanism 51 and the second picking mechanism 52 are synchronously driven by the first driving mechanism, so as to realize the synchronous picking and placing of the corresponding first pole piece; the third picking mechanism 53 is independently driven by the second driving mechanism; the fourth picking mechanism 54 and the fifth picking mechanism 55 are synchronously driven by the third driving mechanism, so as to realize the synchronous picking and placing of the corresponding first pole piece.

[0074] Alternatively, the first picking mechanism 51, the second picking mechanism 52, the fourth picking mechanism 54, and the fifth picking mechanism 55 are synchronously driven by the same driving mechanism, and the third picking mechanism 53 is independently driven by another driving mechanism.

[0075] Specifically, when the second picking mechanism 52 picks up the first pole piece on the first transport mechanism 10, the first picking mechanism 51 picks up the first pole piece on the first pole piece positioning mechanism 31, the third picking mechanism 53 releases the first pole piece picked up from the first transport mechanism 10 to the first pole piece cache mechanism 45, the fourth picking mechanism 54 releases the first pole piece picked up from the first pole piece cache mechanism 45 to the second pole piece positioning mechanism 42, and the fifth picking mechanism 55 releases the first pole piece picked up from the second pole piece positioning mechanism 42 to the second stacking table 43.

[0076] Afterwards, the second picking mechanism 52 transports and releases the first pole piece to the first pole piece positioning mechanism 31, the first picking mechanism 51 transports the first pole piece and releases it to the first stacking platform 33, the third picking mechanism 53 moves unloaded to the first transport mechanism 10 and picks up the first pole piece on the first transport mechanism 10, the fourth picking mechanism 54 moves unloaded to the first pole piece cache mechanism 45 and picks up the first pole piece thereon, and the fifth picking mechanism 55 moves unloaded to the second pole piece positioning mechanism 42 and picks up the first pole piece thereon.

[0077] Afterwards, the second picking mechanism 52 returns unloaded to the first transport mechanism 10 and picks up the first pole piece thereon, the first picking mechanism 51 returns unloaded to the first pole piece positioning mechanism 31 and picks up the first pole piece thereon, the third picking mechanism 53 transports and releases the first pole piece to the first pole piece cache mechanism 45, the fourth picking mechanism 54 transports and releases the first pole piece to the second pole piece positioning mechanism 42, and the fifth picking mechanism 55 transports and releases the first pole piece to the second stacking table 43.

[0078] The above is a cycle process in which the first transport component 50 transports the first pole piece to the first stacking component 30 and the second stacking component 40. It can be seen that the first transport component 50 can transport the first pole piece to the first stacking component 30 and the second stacking component 40 respectively in one transport process, which is greatly beneficial to improving the working efficiency of the stacking machine 100.

[0079] Continue to participate Figure 3 and Figure 4 The second transport assembly 60 transports the second electrode piece on the second transport mechanism 20 to the second electrode piece buffer mechanism 35, transports the second electrode piece on the second electrode piece buffer mechanism 35 to the third electrode piece positioning mechanism 32, and transports the second electrode piece on the third electrode piece positioning mechanism 32 to the first stacking platform 33. The processes of transporting the second electrode piece to the second electrode piece buffer mechanism 35, transporting the second electrode piece to the third electrode piece positioning mechanism 32, and transporting the second electrode piece to the first stacking platform 33 are performed simultaneously, thereby improving the efficiency of the stacking machine 100.

[0080] The second handling component 60 transports the second pole piece on the second transport mechanism 20 to the fourth pole piece positioning mechanism 41, and transports the second pole piece on the fourth pole piece positioning mechanism 41 to the second laminating table 43. Among them, the processes of transporting the second pole piece to the fourth pole piece positioning mechanism 41 and transporting the second pole piece to the second laminating table 43 are carried out synchronously, thereby improving the efficiency of the laminator 100.

[0081] Specifically, the second handling component 60 includes a sixth picking mechanism 61, a seventh picking mechanism 62, an eighth picking mechanism 63, a ninth picking mechanism 64, and a tenth picking mechanism 65.

[0082] The sixth picking mechanism 61 is used to transport the second pole piece on the fourth pole piece positioning mechanism 41 to the second laminating table 43, the seventh picking mechanism 62 is used to transport the second pole piece on the second transport mechanism 20 to the fourth pole piece positioning mechanism 41, the eighth picking mechanism 63 is used to transport the second pole piece on the second transport mechanism 20 to the second pole piece buffer mechanism 35, the ninth picking mechanism 64 is used to transport the second pole piece on the second pole piece buffer mechanism 35 to the third pole piece positioning mechanism 32, and the tenth picking mechanism 65 is used to transport the second pole piece on the third pole piece positioning mechanism 32 to the first laminating table 33.

[0083] In this embodiment, the sixth picking mechanism 61 and the seventh picking mechanism 62 are synchronously driven by a fourth driving mechanism, thereby realizing the synchronous picking and placing of the corresponding second pole piece; the eighth picking mechanism 63 is independently driven by a fifth driving mechanism; the ninth picking mechanism 64 and the tenth picking mechanism 65 are synchronously driven by a sixth driving mechanism, thereby realizing the synchronous picking and placing of the corresponding second pole piece.

[0084] Alternatively, the sixth picking mechanism 61, the seventh picking mechanism 62, the ninth picking mechanism 64, and the tenth picking mechanism 65 are synchronously driven by the same driving mechanism, and the eighth picking mechanism 63 is independently driven by another driving mechanism.

[0085] Specifically, when the seventh picking mechanism 62 picks up the second pole piece on the second transport mechanism 20, the sixth picking mechanism 61 picks up the second pole piece on the fourth pole piece positioning mechanism 41, the eighth picking mechanism 63 releases the second pole piece picked up from the second transport mechanism 20 to the second pole piece buffer mechanism 35, the ninth picking mechanism 64 releases the second pole piece picked up from the second pole piece buffer mechanism 35 to the third pole piece positioning mechanism 32, and the tenth picking mechanism 65 releases the second pole piece picked up from the third pole piece positioning mechanism 32 to the first laminating table 33.

[0086] After that, the seventh picking mechanism 62 transports and releases the second pole piece to the fourth pole piece positioning mechanism 41, the sixth picking mechanism 61 transports the second pole piece and releases it to the second lamination table 43, the eighth picking mechanism 63 moves empty to the second transport mechanism 20 and picks up the second pole piece on the second transport mechanism 20, the ninth picking mechanism 64 moves empty to the second pole piece buffer mechanism 35 and picks up the second pole piece thereon, and the tenth picking mechanism 65 moves empty to the third pole piece positioning mechanism 32 and picks up the second pole piece thereon.

[0087] After that, the seventh picking mechanism 62 returns empty to the second transport mechanism 20 and picks up the second pole piece thereon, the sixth picking mechanism 61 returns empty to the fourth pole piece positioning mechanism 41 and picks up the second pole piece thereon, the eighth picking mechanism 63 transports and releases the second pole piece to the second pole piece buffer mechanism 35, the ninth picking mechanism 64 transports and releases the second pole piece to the third pole piece positioning mechanism 32, and the tenth picking mechanism 65 transports and releases the second pole piece to the first lamination table 33.

[0088] The above is a cycle process of the second handling component 60 transporting the second pole piece to the first lamination component 30 and the second lamination component 40. It can be seen that the second handling component 60 can transport the second pole piece to the first lamination component 30 and the second lamination component 40 respectively during one handling process, which is extremely beneficial to improving the efficiency of the laminator 100.

[0089] While the first transport mechanism 10 and the second transport mechanism 20 transport the first pole piece and the second pole piece respectively, the first handling component 50 and the second handling component 60 simultaneously perform the actions of handling the first pole piece and the second pole piece respectively, and during this process, there are also positioning deviation correction and lamination of the first pole piece and the second pole piece. Overall, the working efficiency of the laminator 100 is greatly improved.

[0090] Further, as Figure 2 shown, the laminator 100 further includes a post-processing mechanism 70. The post-processing mechanism 70 is provided on one side of both the first lamination component 30 and the second lamination component 40. The two post-processing mechanisms 70 are arranged at intervals along the second horizontal direction, and the post-processing mechanism 70 is also arranged along the transport lines of the first transport mechanism 10 and the second transport mechanism 20.

[0091] In this embodiment, the two first lamination components 30 arranged along the transport line share a set of post-processing mechanisms 70, and the two second lamination components 40 share another set of post-processing mechanisms 70. The post-processing mechanism 70 is used to process the battery cells on the first lamination component 30 or the second lamination component 40 and transport the battery cells to the next process.

[0092] The post - processing mechanism 70 includes a cutting knife assembly 75, a flat - sticking glue assembly 71 and a grasping assembly 72. The cutting knife assembly 75 is used to cut the separator on the battery cell. The flat - sticking glue assembly 71 is used to bond the cut separator to the battery cell to prevent the separator from detaching from the battery cell. The grasping assembly 72 is used to grasp the battery cell from the first stacking assembly 30 or the second stacking assembly 40 and transport the battery cell to the next process, that is, the grasping assembly 72 is used to grasp the battery cell from the first stacking table 33 or the second stacking table 43. Among them, the grasping assembly 72 can be driven by a lead - screw nut assembly so that the grasping assembly 72 can transport the battery cell to move.

[0093] The post - processing mechanism 70 may further include a U - shaped glue - sticking assembly 74. The grasping assembly 72 transports the battery cell with the cut separator to the U - shaped glue - sticking assembly 74. The U - shaped glue - sticking assembly 74 is used to bond the tape to the circumferential side surface of the battery cell and bond the separator to the circumferential side surface of the battery cell to form a U - shaped glue on the surface of the battery cell.

[0094] The post - processing mechanism 70 may further include a tail - winding assembly 73. The grasping assembly 72 transports the battery cell to the tail - winding assembly 73. The tail - winding assembly 73 is used to wind the separator around the surface of the battery cell. Specifically, the tail - winding assembly 73 drives the battery cell to rotate so that the separator is wound around the surface of the battery cell. The grasping assembly 72 then transports the battery cell with the tail - winding completed to the flat - sticking glue assembly 71 and / or the U - shaped glue - sticking assembly 74. Then the grasping assembly 72 transports the battery cell after the flat - sticking glue treatment or / and the U - shaped glue treatment to the next process.

[0095] The working process of the post - processing mechanism 70 once is as follows: The grasping assembly 72 grasps the battery cell and pulls the separator for a certain distance. The cutting knife assembly 75 cuts the separator between the first separator unwinding assembly 34 or the second separator unwinding assembly 44 and the battery cell. Then the grasping assembly 72 transports the battery cell to the tail - winding assembly 73. The tail - winding assembly 73 drives the battery cell to rotate to wind the separator around the surface of the battery cell for tail - winding. After that, the grasping assembly 72 transports the battery cell with the tail - winding completed to the flat - sticking glue assembly 71 to perform flat - sticking glue on the separator. Then the grasping assembly 72 transports the battery cell to the next process; or, after the tail - winding of the battery cell, the grasping assembly 72 transports the battery cell to the U - shaped glue - sticking assembly 74. After the battery cell is subjected to U - shaped glue - sticking, it is transported to the flat - sticking glue assembly 71, and then the grasping assembly 72 transports the battery cell to the next process; or, after the tail - winding of the battery cell, the grasping assembly 72 transports the battery cell to the U - shaped glue - sticking assembly 74. After the battery cell is subjected to U - shaped glue - sticking, the grasping assembly 72 transports the battery cell to the next process.

[0096] Further, the laminator 100 further includes a battery cell feeding mechanism 80. The battery cell feeding mechanism 80 includes a feeding component 81 and a transfer component 82. The feeding component 81 is disposed between the grasping component 72 and the first transportation mechanism 10 or the second transportation mechanism 20, and the feeding component 81 is used to convey the post-processed battery cells to the next process; the transfer component 82 is arranged along the second horizontal direction and straddles above the two grasping components 72, and is used to pick up the battery cells grasped by the two grasping components 72 arranged at intervals along the second horizontal direction, and convey the battery cells to the feeding component 81.

[0097] Further, the transfer component 82 is also used to transfer battery cells between the post-processing mechanism 70 on the side where the first lamination component 30 is located and the post-processing mechanism 70 on the side where the second lamination component 40 is located, so that the two post-processing mechanisms 70 can share some functional components. For example, the two post-processing mechanisms 70 share the same U-shaped glue pasting component 74 or tail winding component 73, etc.

[0098] As Figure 2 shown, the post-processing mechanism 70 on one side includes a U-shaped glue pasting component 74, and the post-processing mechanism 70 on the other side does not include a U-shaped glue pasting component 74. The transfer component 82 picks up the battery cells from the grasping component 72 of the post-processing mechanism 70 on the other side and transfers them to the U-shaped glue pasting component 74 for U-shaped glue pasting treatment.

[0099] The transfer component 82 can also be used to pick up the battery cells grasped by the grasping component 72 and adjust the posture of the battery cells, and then carry the battery cells with adjusted postures to the U-shaped glue pasting component 74.

[0100] Further, referring to Figure 4 , the present application further provides a slitting and laminating integrated machine 300. The slitting and laminating integrated machine 300 includes a slitter 200 and the laminator 100 as described above. The slitter 200 is disposed at one end of the first transportation mechanism 10 and the second transportation mechanism 20 along the first horizontal direction. The slitter 200 is used to cut and form a first pole piece and a second pole piece, and respectively place the first pole piece and the second pole piece at a set interval on the first transportation mechanism 10 and the second transportation mechanism 20, so as to facilitate the uniform alignment of the first pole piece and the second pole piece with the first lamination component 30 and the second lamination component 40, thereby reducing the difficulty of picking up the first pole piece and the second pole piece. The laminator 100 laminates the first pole piece and the second pole piece into a battery cell and conveys it to the next process.

[0101] Different from the prior art, the present application discloses a laminator and a slitting and laminating integrated machine. By using a first transport mechanism and a second transport mechanism to transport a first electrode sheet and a second electrode sheet respectively, the present application can avoid confusing the first electrode sheet and the second electrode sheet during the conveying process; and by respectively arranging a first lamination assembly and a second lamination assembly on both sides of the transport lines of the first transport mechanism and the second transport mechanism, and respectively arranging a first handling assembly and a second handling assembly on both sides of the first lamination assembly and the second lamination assembly along the first horizontal direction, and the first handling assembly continuously transports the first electrode sheet from the first transport mechanism to the first lamination assembly and the second lamination assembly, and the second handling assembly continuously transports the second electrode sheet from the second transport mechanism to the first lamination assembly and the second lamination assembly, the lamination efficiency of the laminator 100 is improved, and the layout of each component is compact and the upper space of the first transport mechanism and the second transport mechanism is fully utilized, and the overall floor space of the laminator is small.

[0102] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present application.
