Description

Tape sticking device
[technical field]
The present invention relates to the battery manufacturing technology, especially a kind of tape sticking device with non-tensioning mode Continuous pressing device for stereo-pattern.
[background technology]
The electric core of lithium battery is formed by barrier film and pole piece coiling, the end of pole piece must be touched with adhesive tape in the coiling, and this operation is called pastes the termination adhesive tape.Present subsides stop the adhesive tape mode and mostly are a winding subsides pair mode, and this mode is relatively wasted adhesive tape, has taken the battery useful space; And be that the end, the other end that earlier an end of adhesive tape are attached to pole piece stretches and twine and volume is attached on the electric core when twine to paste paying, produced tensile force in the pole piece and to electric core build-up of pressure.This performance to the square lithium battery will be brought very big adverse effect; The adhesive tape amount of using is also more, is unfavorable for reducing cost.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of tape sticking device with non-tensioning mode Continuous pressing device for stereo-pattern.
For solving the problems of the technologies described above, the invention provides a kind of tape sticking device, the actuating unit that comprises bracing frame, rubberizing driving mechanism and driving support movements, bracing frame is provided with the rubberizing roller that can rotate around self central axis, the rubberizing roller is provided with the suction blob of viscose that is communicated with vacuum system, and rubberizing driving mechanism and rubberizing roller form the transmission matching relationship that the rubberizing roller is rotated around self central axis.
When tape sticking device of the present invention is worked, the suction glue position of bracing frame motion earlier, inhale the no glue face that blob of viscose holds adhesive tape, adhesive tape is sheared rear support stand and moves to the rubberizing position again, it is tangent with the electric core of finishing coiling that inhale blob of viscose this moment, adhesive tape on the suction blob of viscose is corresponding to the pole piece end, the direction that the electricity core is pressed when reeling is rotated, produce force of rolling friction between electricity core and the rubberizing roller, the rubberizing roller under the effect of this frictional force to rotate with the direction of electric core direction of rotation, vacuum system stops to vacuumize, and inhales blob of viscose and discharges adhesive tape, and adhesive tape sticks on the end of pole piece on the volume core.
On this basis, further:
The mode that the rubberizing roller is located on the bracing frame is: swing span is hinged on the bracing frame, and the rubberizing roller is articulated on the swing span; Also be provided with on the bracing frame and can draw the swing actuating unit that swing span is swung on bracing frame.Take such structure to control better and inhale blob of viscose in the accurate position of inhaling glue position and rubberizing position.
The fixedly suction blob of viscose that is fixed on the rubberizing roller is set on the blob of viscose and blob of viscose is inhaled in the activity of changeable in order to adapt to of the requirements of different volume cores better, to inhale, fixingly inhales blob of viscose and the movable blob of viscose of inhaling all is communicated with vacuum system length of tape.Can regulate fixing inhale blob of viscose and movable the suction adding and length of blob of viscose by increasing and decreasing the movable blob of viscose of inhaling.
As a kind of concrete form, the rubberizing driving mechanism comprises first friction pulley that is fixed on the rubberizing roller, second friction pulley that can cooperate with first friction pulley formation frictional drive, the rubberizing driving mechanism is provided with power output shaft, the rubberizing driving mechanism forms like this with transmission matching relationship between the rubberizing roller: the two is concentric fixing for first friction pulley and power output shaft, and power output shaft rotates and drives the rubberizing roller and rotate around self central axis when first friction pulley and second friction pulley form frictional drive and cooperate.
In order to guarantee the directivity of support movements, suitable with bracing frame, as to limit the direction of motion of bracing frame under actuating unit drives guiding mechanism is set.
In order further accurately to control the direction of rubberizing roller, the control unit that electrically connects with the rubberizing driving mechanism is set also; First friction pulley is provided with sensing chip, and bracing frame is provided with the transducer suitable with sensing chip, and transducer and control unit electrically connect.
The invention has the beneficial effects as follows: adopt tape sticking device of the present invention, adhesive tape can stick on the state of non-tensioning on pole piece and the volume core, has reduced the adverse effect that electric core is produced pressure and then reduction battery performance because of the tension force in the adhesive tape.Simultaneously, the adhesive tape amount of use is also less, has reduced adhesive tape to the taking of inside battery space, and helps reducing cost, and improves the space utilization efficient and the capacity of battery; The present invention is simple in structure, implements easily.
