Further, the knife-edge positions of the rectangular region correspondence rotor of described thin film through-hole side.
Further, the thickness of described thin film is 12-40 μm.
Further, the length of described through hole rectangular region is less than the length of trapezoid area.
The present invention also provides for a kind of battery pole piece and is coated with the manufacture method of stop gauge continuously, comprises the following steps:
Step a, selects required thin film, cuts out one or more through hole, institute in the side of main film body by designing requirement
State spacing between adjacent two through holes；Wherein the number of through hole is identical with dressing district number, the number at interval and Kong Bo district number
Mesh is identical；
Step b, through hole is cut to rectangular region near the side of main film body；The opposite side of through hole is cut to step sector
Territory, the trapezoidal upper end, is consistent with rectangular width, and identical with the width in dressing district；
Step c, is arranged on the stop gauge cut between rotor and paint roller, the gap through two rollers；Thin film
Main body side is arranged on rotor surface, through-hole side is arranged on the hopper back side, wherein the rectangular region correspondence rotor of thin film through hole
Knife-edge positions.
Further, in step c, stop gauge uses adhesive tape to be fixed on rotor surface.
In a word, the invention have the benefit that the thin film that stop gauge uses pliability, intensity is high of the present invention cuts out
The process needed, is fitted between rotor and paint roller, splits dressing district and Kong Bo district；Due to the size cut and technique
Consistent size, the size being coated with out and to cut size completely the same.Solve needs after using this device and repeatedly reconcile painting by hand
Cloth width and the problem of gap width, save the material of tune machine；The most this thin film can be fitted in paint roller and rotor completely
Knife edge surfaces, the pole piece edge thickness being coated with out is the most without exception, improves the performance of battery.

Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings.
In Fig. 2 one embodiment of the invention, battery pole piece is coated with the structural representation of stop gauge continuously.As in figure 2 it is shown,
Described stop gauge 1 is a thin film.
In the present invention, the material of thin film selects the material with good pliability, high intensity, and specifically this material can be metal
Or nonmetal, such as Copper Foil, PET film etc..
The thickness of thin film is 12-40 μm.
The side of main film body 11 is provided with multiple through hole 12, is provided with interval 13 between adjacent two through holes.
Wherein the number of through hole 12 is identical with the number in dressing district, and the number at interval 13 is identical with the number in Kong Bo district.
Each through hole 12 is rectangular region 121 near the side of main film body 11, and its width is consistent with dressing sector width.
The opposite side of through hole is trapezoid area 122, and the trapezoidal upper end is consistent with dressing sector width, and length of going to the bottom is more than the upper end so that logical
Hole 12 trapezoid area 122 flare opening.The shape at interval 13 and through hole 12 correspondence mutually, i.e. between rectangular region 121
Front end 131, interval also be rectangle, between trapezoid area 122 be spaced tail end 132 be shaped as contrary trapezoidal of opening therewith
Or triangle.
Fig. 3 is the scheme of installation of the stop gauge in Fig. 2.During as it is shown on figure 3, this stop gauge is installed, stop gauge 1
It is arranged on the gap between rotor 2 and paint roller 4, through two rollers；Main film body 11 side is arranged on rotor 2 surface, through hole 12
Side is arranged on hopper 3 back side, the wherein knife-edge positions of the corresponding rotor 2 of the rectangular region 121 of thin film through hole 12.
Embodiment 1
Have employed the Copper Foil material as stop gauge of 15um, design the pole piece in Liang Tiao dressing district as shown in Figure 2
Pattern.
Wherein dressing district shape is consistent, and width is 300mm, and the Kong Bo district between two dressing districts is 40mm.
According to dressing district technological requirement, rectangle 121 region is cut into the width of Article 1 dressing district technological requirement
300mm, a length of 40mm.The a length of 200mm of trapezoid area 122.
It is 40mm that Liang Tiao dressing district is spaced front end 131 width accordingly, and length is also 40mm.Interval tail end 132 is triangle
Shape, its a length of 200mm.
By stop gauge 1 according to shown in Fig. 3, with adhesive tape, main body 11 side of stop gauge is pasted onto rotor 2 surface, through hole
12 sides are pasted onto hopper 3 back side.The rectangular region 121 cut must be corresponding at rotor 2 knife-edge positions, and makes stop gauge 1
It is close to the surface of rotor 2.Then install hopper 3, hopper 3 adds slurry coating and i.e. can get wide pole coating
As shown in two wide bands middle in Fig. 4.Dressing sector width is 300mm, and middle gap is 40mm, the chi of correspondence position
Width that is very little and that cut is completely the same.
Although the present invention is open as above with preferred embodiment, but it is not for limiting the present invention, any this area
Technical staff without departing from the spirit and scope of the present invention, may be by the method for the disclosure above and technology contents to this
Bright technical scheme makes possible variation and amendment, therefore, every content without departing from technical solution of the present invention, according to the present invention
Technical spirit any simple modification, equivalent variations and modification that above example is made, belong to the technology of the present invention side
The protection domain of case.
