Abstract
The utility model discloses a measuring device of folded dislocation quantity and folded arch-shaped quantity of a plastic film; three rulers which are deployed on the same side with equal spacing in parallel are arranged on the same plane of a support; the baselines of the three rulers are on the same line, and scales for measuring distance are marked on both sides of the baseline of the middle ruler. When in use, a film sample to be tested is folded and straightened on the three rulers along the direction in which the baseline extends, and the edges of both layers of the film on the rulers on both sides correspond to the baselines of the rulers. The folded dislocation quantity and folded arch-shaped quantity of the film can be measured by reading the distance between the edges of the upper layered film and the lower layered film of the middle ruler as well as the distance from the edges of the upper layered film and the lower layered film to the baselines. The measuring device can simply and conveniently measure the folded dislocation quantity and folded arch-shaped quantity of the plastic film.
Description
Technical field
The utility model relates to the device that is used to measure plastic sheeting doubling magnitude of misalignment and the arc amount of doubling.
Background technology
Need in the lithium ion battery to use microporous plastic sheet as barrier film, it both can guarantee that lithium ion can waltz through when battery charging and discharging, can make the positive and negative polarities of battery separate and avoid being short-circuited again.In the process of manufacture of lithium ion battery,, need together to be reeled with battery battery core as the plastic sheeting that barrier film uses, in the winding process, film layer by layer between can misplace because of distortion, when magnitude of misalignment is excessive, can cause electric core to use, produce waste product.
In order to control in the electric core winding process, because of the rejection rate that the distortion of plastic sheeting coiling produces, battery production producer before the microporous plastic sheet that uses, all needs the doubling magnitude of misalignment and the arc amount of doubling of film are measured in advance usually.Guarantee to have less distortion after the plastic sheeting that uses is reeled, the magnitude of misalignment between is less layer by layer, thereby effectively controls the rejection rate of electric core winding.
At present, the doubling magnitude of misalignment of plastic sheeting and the arc amount of doubling do not have special survey instrument, all directly measure by chi usually.The sample of the standard length under from film rolling, cutting out, be folded in half and place the levelling bench surface, keep its two ends concordant, and two ends are placed on the datum line, measure distance between the distance that staggers between its upper and lower double-layer films in midline position place and two-layer up and down and datum line with dipstick metering.Wherein, the distance that upper and lower double-layer films staggers is called as the doubling magnitude of misalignment, and the maximal value in the distance of deviation is the arc amount of doubling between upper and lower two-layer and datum line.The inconvenience of said method measuring operation, measuring accuracy is lower.
Summary of the invention
The utility model is intended to provide a kind of doubling magnitude of misalignment of measurement plastic sheeting and device of the arc amount of doubling of being specifically designed to, and is simple, convenient with its doubling magnitude of misalignment and arc amount of doubling of measuring plastic sheeting, and can conveniently guarantee measuring accuracy.
The measurement mechanism of plastic sheeting doubling magnitude of misalignment of the present utility model and the arc amount of doubling, comprise support, the same side of support is equally spaced to be equipped with the ruler that three levels are stretched out, these three rulers parallel to each other, be positioned at same surface level, its datum line is located along the same line, and middle ruler all indicates the scale mark of measuring distance in the both sides of datum line.
The measurement mechanism of plastic sheeting doubling magnitude of misalignment described in the utility model and the arc amount of doubling on the same plane of its support, has three parallel rulers that are installed on the equidistant layout of its same side, and three are positioned at same straight line to the datum line of ruler.During measurement, after the film sample doubling to be measured, one end is enclosed within on the ruler of a side, the datum line of this ruler is aimed at the edge, and the other end is walked around the ruler upside of opposite side behind the ruler through the centre, and by counterweights such as clip and corresponding counterweights, along the direction that datum line extends that film is stretching, adjust film, make film aim at the datum line of this side ruler equally in the two-layer edge that is positioned at this side ruler up and down.Film after the doubling all is positioned on the datum line at the edge at both sides ruler place, can measure the doubling magnitude of misalignment amount of film by the distance between the upper and lower double-layer films edge, ruler place in the middle of reading; By reading upper and lower double-layer films edge, intermediate film place, and get higher value wherein, can obtain the arc amount of doubling to the distance between datum line.
As seen, use said apparatus the doubling magnitude of misalignment and the arc amount of doubling of MEASUREMENTS OF THIN simply and easily.And the precision of measurement directly by the precision decision of ruler, by adjusting the precision of ruler, both can change the measuring accuracy of arc amount of doubling and doubling magnitude of misalignment, therefore, by selecting to install on the support precision of ruler, can guarantee measuring accuracy easily.

Embodiment
The measurement mechanism of a kind of plastic sheeting doubling magnitude of misalignment and the arc amount of doubling, as Fig. 1, Fig. 2, Fig. 3, comprise support 1, support by the horizontal base seat board 10 of bottom, with the perpendicular fixed frame 11 of bedplate, one side of fixed frame is equally spaced to be equipped with the ruler 2 that three levels are stretched out, these three rulers parallel to each other, be positioned on the same surface level, its datum line is located along the same line, middle ruler all indicates the scale mark that measuring distance is used in the both sides of datum line.
During measurement, after the film sample doubling to be measured, place along the direction that datum line extends, the one end is enclosed within on the ruler 2 of a side, and the datum line of this ruler is aimed at the edge, and the other end is behind the ruler 2 through the centre, walk around ruler 2 upsides of opposite side, and, adjust film by on the stretching ruler that is hung on this side of counterweights such as clip and corresponding counterweight, make film aim at the datum line of this side ruler equally in the two-layer edge that is positioned at this side ruler up and down.
Claims (1)
1. the measurement mechanism of plastic sheeting doubling magnitude of misalignment and the arc amount of doubling, it is characterized in that: comprise support, the same side of support is equally spaced to be equipped with the ruler that three levels are stretched out, these three rulers parallel to each other, be positioned at same surface level, its datum line is located along the same line, and middle ruler all indicates the scale mark of measuring distance in the both sides of datum line.
