40 and membrane unwinding system 50 connect.Controller controls folded battery core mechanism 10 and stacks pole piece, and control membrane unwinding system 50 will
Diaphragm, which exports, gives pendulum diaphragm mechanism 20, then controls pendulum diaphragm mechanism 20 and diaphragm is covered on pole piece；When diaphragm pendulum roller 21 covers
After complete last a piece of pole piece, controller controls the first diaphragm clamping and rotating system 30 and clamps diaphragm, and controls and cut diaphragm mechanism
40 cut off the diaphragm between the first diaphragm clamping and rotating system 30 and lamination stacking table 11；After cutting off diaphragm, then control
First diaphragm clamping and rotating system 30 rotates clockwise 180 ° in vertical plane, to commutate to the diaphragm of clamping；After the completion of commutation,
The playback of the first diaphragm clamping and rotating system 30 is controlled again.When the second sensing element 53 detects that diaphragm end is arranged in first marks
When label, control connects the main diaphragm coiled strip that the main diaphragm coiler 51 of 55 pairs of diaphragm mechanism releases and secondary diaphragm coiler 52 is released
The secondary diaphragm coiled strip tape splicing of releasing forms engaging portion, and second is labeled on the engaging portion, then controls the diaphragm pendulum movement of roller 21
To the left side of lamination stacking table 11；After diaphragm pendulum roller 21 is moved to the left side of lamination stacking table, 30 ' of the second diaphragm clamping and rotating system is controlled
Diaphragm is clamped, control cuts diaphragm mechanism 40 and cuts off the diaphragm after clamping；After diaphragm is cut off, the second diaphragm of control is clamped
30 ' of rotating mechanism rotates clockwise 180 ° in vertical plane, then controlled level driving assembly drives the second diaphragm to clamp whirler
The mobile a certain distance in the direction of 30 ' of structure to separate first diaphragm clamping and rotating system 30, meanwhile, the first diaphragm of control clamps rotation
Rotation mechanism 30 clamps diaphragm, will the diaphragm section containing engaging portion it is exposed；Will the diaphragm section containing engaging portion it is exposed after, control
Zhi Qie diaphragm mechanism 40 cuts off the diaphragm section for containing engaging portion, to complete the rejecting to useless diaphragm.
In the present embodiment, controller controls the sequencing of movement and movement between above-mentioned each mechanism, can will be above-mentioned
The sequencing of movement and movement between each mechanism is set as program, to realize this lamination device of automation control.
The course of work of the lamination device of diaphragm capable of reversing provided by the present embodiment is as follows：
After controller judges that last a piece of pole piece has been folded by folded battery core mechanism 10, control pendulum roller driving assembly 22 drives diaphragm
Pendulum roller 21 is moved to the left side of lamination stacking table 11 by the right side of lamination stacking table 11；Control the first diaphragm clamping and rotating system 30 will be located at every
Film is put the diaphragm between roller 21 and lamination stacking table 11 and is clamped；After the first diaphragm clamp system 30 clamps diaphragm, cutter is controlled
Driving assembly 42 drive cutter 41 move up, will be located between the first diaphragm clamping and rotating system 30 and lamination stacking table 11 every
Film cutting, while driving upside down component 23 and diaphragm pendulum roller 21 is driven to move up, to avoid the first diaphragm clamping and rotating system 30；
First diaphragm clamping and rotating system 30 rotates clockwise 180 ° in vertical plane, to commutate to the diaphragm of clamping；After commutation, the
One diaphragm clamping and rotating system 30 unclamps diaphragm, and diaphragm recycled by membrane unwinding system 50, when the first sensing element detect every
When film cut edge, folds battery core mechanism 10 and compress diaphragm, restart to stack pole piece.
When the second sensing element 53, which detects, sets the first label, meets diaphragm mechanism 55 and discharge main diaphragm coiler 51
The end of main diaphragm coiled strip out is connected with the head end tape splicing for the secondary diaphragm coiled strip that secondary diaphragm coiler 52 releases to be formed
Engaging portion, and second is labeled in the engaging portion；After third sensing element 54 detects the second label, the second diaphragm clamps rotation
30 ' of rotation mechanism clamps diaphragm, cuts diaphragm mechanism 40 and cuts off diaphragm, and 30 ' of the second diaphragm clamping and rotating system drives cutting again
Diaphragm afterwards rotates clockwise 180 ° in vertical plane, and under the driving of horizontal drive component, clamps to far from the first diaphragm
The direction of rotating mechanism 30 is mobile, meanwhile, the first diaphragm clamping and rotating system 30 clamps diaphragm, will containing engaging portion every
Film section is exposed, then is cut off the diaphragm section by cutting diaphragm mechanism 40, to complete the rejecting to useless diaphragm.
In conclusion the lamination device of diaphragm capable of reversing provided by the present embodiment, pendulum diaphragm mechanism 20 is by membrane unwinding
The diaphragm coiled strip that system 50 is released is covered on the pole piece that folded battery core mechanism 10 is stacked, when folded battery core mechanism 10 has been folded most
Afterwards when last a piece of pole piece, the clamping component 31 of the first diaphragm clamping and rotating system 30 is stretched out, and diaphragm is clamped, then, pendulum every
Film mechanism 20 is moved to the other side of folded battery core mechanism 10, and clamping component 31 rotates clockwise 180 ° in vertical plane with by diaphragm
Commutation cuts diaphragm mechanism 40 and cuts off the diaphragm between the first diaphragm clamping and rotating system 30 and folded battery core mechanism 10, real
Showed the commutation to diaphragm coiled strip, prevent from having folded battery core finally occur double-baging after a piece of pole piece diaphragm the phenomenon that generation.When
When first sensing element detects diaphragm cut edge, restart folded battery core.In this lamination device, main diaphragm coiled strip and secondary membrane coil
The end of material is respectively provided with the first label, by the second sensing element 53 detect the first label, when detecting the first label, connect every
The head end tape splicing of the end of main diaphragm coiled strip and secondary diaphragm coiled strip is formed engaging portion by film mechanism 55, and in the second mark of engaging portion patch
Label, then by the way that third sensing element the second label of detection apart from 11 pre-determined distance of lamination stacking table is arranged in, so that combination will be contained
The diaphragm section in portion is cut off, and has effectively saved diaphragm cost, and then saved production cost.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
