Description
Technical field
The utility model relates to lithium-ion battery module maintenance technology field, particularly a kind of stretching device of lithium ion battery separator semi-fixed type.
Background technology
batterybarrier film refers to one deck diaphragm material between anode and negative pole, it is part very crucial in battery, have a direct impact battery security and cost, its Main Function is: the positive and negative electrode of battery is separated, prevent the two poles of the earth from contacting and short circuit, allow the ion in electrolyte freely pass through between both positive and negative polarity.The ionic conduction ability of battery diaphragm is directly connected to the overall performance of battery; effect is the rising making battery energy Limited Current when overcharging or temperature raises; prevent battery short circuit from setting off an explosion; there is the self-closing protective effect of micropore, battery user and equipment are played to the effect of safeguard protection.
Battery diaphragm is when production line runs, and especially when high-speed cruising, because fabric width is wider, barrier film is too thin, easily wrinkling, causes barrier film to occur wrinkle, and edge is wrinkling more serious; But manually the limit rolled is flattened or middle hanging portion is flattened, process very difficult, workload is large, and efficiency is low.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model devises a kind of stretching device of lithium ion battery separator semi-fixed type, uses machine smoothing wrinkle, and crimping is easy to flatten, and avoid middle sagging, operating efficiency is high.
The technical solution adopted in the utility model is, a kind of stretching device of lithium ion battery separator semi-fixed type, key is: comprise two stretching beaming roller groups and fixture, described fixture comprises two supports, a brace summer, two side plates and a base, two described side plates are separately fixed at the both sides of base upper surface, a brace summer is fixed with in the bottom of two side plate apparent surfaces, the both sides of brace summer side are fixed with a support respectively, described stretching beaming roller group is arranged on support, two stretching beaming roller groups are oppositely arranged, described stretching beaming roller group comprises the first beaming roller and the second beaming roller, first beaming roller is arranged on above the second beaming roller, first beaming roller is hingedly fixed on support, second beaming roller is by being bolted on support.
The first described beaming roller and the angle of the second beaming roller are 0 °.
The length of the first described beaming roller is 8-10cm, and the length of the second beaming roller is 8-10cm.
The first described beaming roller and the spacing of the second beaming roller are 0-25 μm.
The beneficial effects of the utility model are, this device respectively adds a beaming roller group in the both sides of barrier film beaming roller, and by the angle of two beaming rollers in adjustment stretching beaming roller group, clamping barrier film, reaches the effect of stretching smoothing wrinkle, and crimping is easy to flatten; Apply the power stretched out to barrier film both sides, alleviate the sinking that barrier film mid portion causes due to gravity; Fixing barrier film, the work septation of avoiding teetertotters.Machine smoothing wrinkle is higher than man efficiency, and smoothing wrinkle more easily processes.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model.
Fig. 2 is vertical view of the present utility model.
In accompanying drawing, 1 is the first beaming roller, and 2 is second beaming rollers, and 3 is brace summers, and 4 is side plates, and 5 is bases, and 6 is supports, and 7 is barrier film beaming rollers.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Specific embodiment, as Fig. 1, shown in Fig. 2, a kind of stretching device of lithium ion battery separator semi-fixed type, key is: comprise two stretching beaming roller groups and fixture, described fixture comprises two supports 6, a brace summer 3, two side plates 4 and a base 5, two described side plates 4 are separately fixed at the both sides of base 2 upper surface, a brace summer 3 is fixed with in the bottom of two side plate 4 apparent surfaces, the both sides of brace summer 3 side are fixed with a support 6 respectively, described stretching beaming roller group is arranged on the frame 6, in order to process the fold on barrier film both sides, two described stretching beaming roller groups are oppositely arranged, described stretching beaming roller group comprises the first beaming roller 1 and the second beaming roller 2, according to the fold width on barrier film both sides, the length of the first described beaming roller 1 is 8-10cm, the length of the second beaming roller 2 is 8-10cm, first beaming roller 1 is arranged on above the second beaming roller 2, make the first beaming roller 1 and the second beaming roller about 2 concurrent working, the first described beaming roller 1 and the spacing of the second beaming roller 2 are 0-25 μm, under blank state, the spacing of the first beaming roller 1 and the second beaming roller 2 is 0, under using state, the spacing of the first beaming roller 1 and the second beaming roller 2 is 6-25 μm, first beaming roller 1 is hingedly fixed on support 6, spring is provided with between twisted axis and support 6, first beaming roller 1 can rotate up and down, first beaming roller 1 can at the rotation with in surface of two roller center line compositions around the axle of its stiff end, it relies on gravity and spring tension to press down and contacts with the second beaming roller 2, second beaming roller 2 is by being bolted on support 6, second beaming roller 2 is fixed, only can around its central axis, the first described beaming roller 1 and the angle of the second beaming roller 2 are 0 °, the clamping angle of stretching beaming roller group can adjust, namely the shearing force of stretching beaming roller group can adjust, the mid portion of barrier film is subject to the outside tensile force of stretching beaming roller group, contribute to improving evenness, simultaneously, tensile force is relevant with the angle of barrier film direction of advance with roller, stretching beaming roller group is larger to the barrier film direction of advance anglec of rotation, the tensile force outside to barrier film is larger.The utility model is the flattening stretching device of semi-fixed type, and this device respectively adds a beaming roller group in the both sides of barrier film beaming roller, and by the angle of two beaming rollers in adjustment stretching beaming roller group, clamping barrier film, reaches the effect of stretching smoothing wrinkle, and crimping is easy to flatten; Apply the power stretched out to barrier film both sides, alleviate the sinking that barrier film mid portion causes due to gravity; Fixing barrier film, the work septation of avoiding teetertotters.Machine smoothing wrinkle is higher than man efficiency, and smoothing wrinkle more easily processes.
