As shown in figure 4, the automatic tape-alternation device further include for fix a pair of of mounting assembly of the automatic tape-alternation device 1 with And support base 135.Each mounting assembly includes the hinged seat 136 that can be fixed to workbench, the first sliding rail 161, the first sliding rack 162 and adjustment cylinder 163, the adjustment cylinder 163 connect the hinged seat 136 and first sliding rack 162.The support base 135 It is supported between two mounting assemblies.First sliding rack 162 is pushed by the adjustment cylinder 163, makes it in first sliding rail 161 It slides up and down, can adjust the position of the automatic hoop device 1.Each mounting assembly further includes limited block 711, the limited block 711 Movement travel for limiting first sliding rack 162.
The controller of the automatic tape-alternation device 1 is arranged in the operation interface 960.The controller is driven with using pole piece material strip Motivation structure 2, alternate polarities sheet stock tape drive mechanism 3, splicing equipment 1, rectifying device of electrode sheet 3, rectifying device of electrode sheet 4, garbage collection The cylinders such as axis are electrically connected, to drive work compound between each mechanism to be automatically performed feeding and tape swapping.
The tape splicing course of work introduced below:
To use pole piece material wheel 820 working, for alternate polarities piece material wheel 821.Material in use pole piece material wheel 820 When volume runs low, pressure sensor 930 is alarmed to controller, and press belt mechanism, which pushes down currently used pole piece, does not allow it dynamic.At this moment, hand Dynamic the first tape splicing sucker 729 and the second tape splicing that spare pole piece in alternate polarities piece material wheel 821 is passed through to automatic splicing equipment 1 It is connect again with garbage collection axis 941 between sucker 769.Start automatic splicing equipment 1, which connects with second Band sucker 769 is contour to be sucked this to patch and uses pole piece material strip and two pole piece material strips of alternate polarities piece material strip.
Pole piece knife 732 is cut under the action of cutting knife cylinder 734 from the first tape splicing sucker 729 or the second tape splicing sucker 769 Two pole piece material strips of cut-out are stretched out in centre, and then garbage collection axis 941 and unreeling shaft 822 are unreeling motor 901 and garbage collection Turbin generator is rotated by, and two clout pole piece material strips is driven to be detached from two tape splicing suckers, and the first tape splicing sucker 729 and second connects Band sucker 769.After removing clout, the pole piece material that the first tape splicing sucker 729 and the second tape splicing sucker 769 are drawn is using pole piece The initial part of material strip remainder and alternate polarities piece material strip.Then the standby gluing mechanism in controller driving left side is for glue, by the first patch Gluing mechanism rubberizing uses this from left side the cut-out interface rubberizing of pole piece material strip and alternate polarities piece material strip;Then controller drives Right side, for glue, uses this from right side by the second adhesive tape rubberizing mechanism rubberizing the cut-out of pole piece material strip and alternate polarities piece material strip for gluing mechanism Interface rubberizing.
The first adhesive tape and the second adhesive tape on the standby gluing mechanism in left and right start standby glue, such as the first feeding machine by feed mechanism The standby rubber tire of structure crosses glue gear wheel 213, crosses glue halo 214 and crosses glue halo 215.Across doubling mechanism, such as through the second folder Doubling fixed block 116 in gluing mechanism and doubling moving block 117.Steady adhesive tape is pressed from both sides by doubling mechanism, for example, first laminated rubber machine The first doubling cylinder 239 effect of structure is lower so that doubling moving block 117 closes up with doubling fixed block 116 and clamps adhesive tape, the The promotion of one drawing glue cylinder 237 makes the first rubberizing movable plate 409 move forward, then rubberizing sucker 430 move forward close to With absorption adhesive tape.Then, exactly the first moulding cylinder 349, which starts, drives the rotation of the first moulding block 346 that will be stretched from doubling mechanism The adhesive tape gone out is pressed on the first rubberizing sucker 430, after adhesive tape is compressed by the first rubberizing sucker 430 and the first moulding block 346, doubling The adhesive tape clamped unclamps in mechanism, and then the first rubberizing movable plate 409 retracts origin-location, and doubling mechanism clamps adhesive tape again.Two The clamped adhesive tape of head is cut off by bale splitter structure, for example, being cut off by the rubber knife 106 of the first bale splitter structure.The glue section quilt of cut-out Rubberizing sucker is sucked, for example is sucked by the first rubberizing sucker 430, and the first rubberizing sucker 430 that film is sucked moves up and the Two tape splicing suckers 769 connect patch to paste the cut-out interface side of the two poles of the earth piece material strip with glue section.Similarly, the second patch Glue sucker is moved up with the first tape splicing sucker 729 to patch, is touched the two poles of the earth piece material strip in the other side and is cut off interface, realizes both sides Paste connection.Finally, the remaining alternate polarities piece material strip that new tape splicing is drawn using pole piece material strip is worked on, automatic to realize Tape swapping change of lap.Vice versa.
The automatic tape-alternation device for electric core winding of the present embodiment cuts the adhesive tape of required length by standby gluing mechanism, The cut-out of pole piece material strip and alternate polarities piece material strip is automatically used this by first adhesive tape rubberizing mechanism and the second gluing structure again Interface completes double sided stick adhesive, and providing tape splicing effect, preferably full-automatic tape swapping device uses pole piece material to realize automatic tape-alternation When band runs low, alternate polarities piece material strip is connect with this using pole piece material strip on automatic tape-alternation device, is worked on without shutdown. Meanwhile garbage collection axis is arranged in the automatic tape-alternation device for electric core winding of the present embodiment, can remove extra clout in time.This The automatic tape-alternation device for electric core winding of embodiment also sets up rectifying device of electrode sheet, ensures pole during pole piece tape splicing Piece can accurate alignment, improve equipment winding battery core yields.
Above is only an example of the present application, it is not intended to limit the scope of the claims of the application, it is every in the application Application design under, using equivalent structure transformation made by present specification and accompanying drawing content, or directly/be used in it indirectly He is included in the scope of patent protection of the application relevant technical field.
