Abstract
The utility model discloses an automatic cutting device of a cell diaphragm, which comprises a guide roller (1), a diaphragm roll (2), a discharge motor (3), a limit rod (4), a sensor (5), a driving motor (6) and a cutter (7), wherein the diaphragm roll (2), the discharge motor (3), the guide roller (1), the driving motor (6) and the cutter (7) are sequentially arranged from front to back on a rack. The utility model is characterized in that the limit rod (4) is arranged between the discharge motor (3) and the guide roller (1), and the limit rod (4) makes unwound diaphragms of the diaphragm roll droop downwards in front of the guide roller (1). According to the device disclosed by the utility model, the diaphragm is in a natural droop state before entering the driving motor, and frictional resistance in feeding is reduced, so the cutting accuracy of the diaphragm is improved.
Description
Technical field
The utility model belongs to small rechargeable battery technology field, is specifically related to improve the battery diaphragm automatic cutting means that battery diaphragm cuts precision.
Background technology
The small rechargeable battery diaphragm mostly is nonwoven fabrics or the hot pressing film that organic fiber is made greatly, and quality is softer.When the industrialization battery production, the barrier film of rolling need be cut into the monolithic barrier film of given size.It is low to cut efficient by hand, and cuts low precision, influences the conformability of battery performance.In recent years, specialized factory has developed the automatic diaphragm guillotine, though improved production efficiency, in use finds to cut still out of reach requirement of precision, traces it to its cause that it is too big to be that barrier film enters when driving battery friction drag, causes the charging size fluctuation.
Summary of the invention
The purpose of this utility model is: a kind of battery diaphragm automatic cutting means is provided, alleviates barrier film and enter friction drag when driving battery, avoid the charging size fluctuation, guarantee to cut precision.
Technical solution of the present utility model is: this cutting means comprises guiding roller, membrane coil, blowing motor, position-limited lever, inductor, drive motor and cut-off knife, membrane coil, blowing motor, guiding roller, drive motor and cut-off knife are installed on frame in the past backward successively, it is characterized in that: between blowing motor and guiding roller position-limited lever is installed, the barrier film that position-limited lever puts down membrane coil is the nature hang in the place ahead of guiding roller.
Wherein, inductor is installed below position-limited lever, inductor connects blowing motor and drive motor.
During work, blowing motor, inductor, position-limited lever are controlled the blowing of membrane coil jointly, are in the nature hang all the time before making mode separation strapping enter drive motor, and cut-off knife cuts into mode separation strapping the battery diaphragm of specified length automatically then.
The utility model is provided with position-limited lever and inductor before drive motor and cut-off knife, be in the nature hang when allowing the membrane coil blowing all the time, reduces the resistance that barrier film enters drive motor, improves to cut precision continuously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 guiding roller, 2 membrane coil, 3 blowing motors, 4 position-limited levers, 5 inductors, 6 drive motor, 7 cut-off knives.
The specific embodiment
As shown in Figure 1, this cutting means comprises guiding roller 1, membrane coil 2, blowing motor 3, position-limited lever 4, inductor 5, drive motor 6 and cut-off knife 7, membrane coil 2, blowing motor 3, guiding roller 1, drive motor 6 and cut-off knife 7 are installed on frame in the past backward successively, it is characterized in that: position-limited lever 4 is installed between blowing motor 3 and guiding roller 1, and the barrier film that position-limited lever 4 puts down membrane coil is the nature hang in the place ahead of guiding roller 1.
Wherein, inductor 5 is installed below position-limited lever 4, inductor 5 connects blowing motor 3 and drive motor 6.
During work, the blowings of blowing motor 3, inductor 5, position-limited lever 4 common control membrane coil 2 are in the nature hang before making mode separation strapping enter drive motor 6 all the time, and cut-off knife 7 cuts into mode separation strapping the battery diaphragms of specified length automatically then.
Claims (2)
1. battery diaphragm automatic cutting means, this cutting means comprises guiding roller (1), membrane coil (2), blowing motor (3), position-limited lever (4), inductor (5), drive motor (6) and cut-off knife (7), membrane coil (2), blowing motor (3), guiding roller (1), drive motor (6) and cut-off knife (7) are installed on frame in the past backward successively, it is characterized in that: between blowing motor (3) and guiding roller (1) position-limited lever (4) is installed, the barrier film that position-limited lever (4) puts down membrane coil is the nature hang in the place ahead of guiding roller (1).
