As shown in Figure 1, being additionally provided with fine tuning clearance mechanism 5, the fine tuning clearance mechanism 5 between fixing roller 31 and pressure roller 32
For adjusting the size of the working clearance between fixing roller 31 and pressure roller 32.Since coating process is an Embedded mistake
Journey, is exactly embedded in coating materials 24 with certain pressure the applying area 100 of battery pole piece, and battery pole piece coated with film is compared to covering
Battery pole piece before film can be more thinning.It is to have a certain proportion of, the too many painting that can destroy battery pole piece that battery pole piece is thinning
The structure in cloth area 100, very little coating materials 24 cannot be substantially embedded into applying area 100 again, therefore the work in the case where overlay film power is constant
The size for making gap just seems especially important.In addition, the thickness of unlike material and the battery pole piece of performance is inconsistent, it is required
Working clearance is not also identical, and if the thickness of graphite coating layer is about 0.1mm~0.2mm, the thickness of cobalt acid lithium coating layer is about
For 0.05mm~0.15mm, the thickness of LiFePO4 coating layer is about 0.18mm~0.3mm, if not adjusting good berth gap
Qualified product cannot just be produced.The fine tuning clearance mechanism 5 of the present embodiment uses on-line tuning, has exactly changed a kind of battery pole piece
Afterwards, the working clearance is adjusted while doing coating technique in debugging process, the battery pole piece of same specification is just after confirmation is qualified
Without having adjusted again.
As shown in Figure 1 and Figure 5, fine tuning clearance mechanism 5 mainly includes the 4th motor 51, slide block assembly 52,53 and of upper skewback
Lower skewback 54.Wherein, upper skewback 53 is fixed in pressure roll bearing seat 36, and lower skewback 54 is fixed on fixing roller bearing block 35, sliding
Block assembly 52 is made of screw rod 521 and sliding block 522, and sliding block 522 is slidably connected between skewback 53 and lower skewback 54, silk
One end of bar 521 is connected through a screw thread structure and is connected with sliding block 522, and the other end of screw rod 521 and the 4th motor 51 are sequentially connected.
In the present embodiment, upper skewback 53 and the joint face of sliding block 522 are corresponding inclined surface, and when work, the 4th motor 51 drives silk
Bar 521 rotates, and screw rod 521 moves sliding block 522 along the axis direction of screw rod 521 in rotation, and sliding block 522 is in moving process
The relative position of skewback 53 in change, thus change the relative position of pressure roll bearing seat 36, the final movement for realizing fine tuning, such as
4th motor 51 rotation, one circle, working clearance change 0.005mm.It is understood that in other embodiments can also be in cunning
Inclined surface is set at the joint face of block 522 and lower skewback 54.
As shown in Figure 1, coating materials conveying mechanism 2 includes coating materials unreeling structure, coating materials rolling-up mechanism and traction film 23.Wherein,
Coating materials unreeling structure and coating materials rolling-up mechanism include two, respectively the first coating materials unreeling structure 21a, the first coating materials unreeling machine
Structure 21b, the second coating materials rolling-up mechanism 22a and the second coating materials rolling-up mechanism 22b, the first coating materials unreeling structure 21a and the first coating materials
Rolling-up mechanism 22a corresponds to fixing roller 31, and the second coating materials unreeling structure 21b and the second coating materials rolling-up mechanism 22b correspond to pressure
Roller 32.Traction film 23 on first coating materials unreeling structure 21a and the first coating materials rolling-up mechanism 22a is coated in fixing roller 31, the
Traction film 23 on two coating materials unreeling structure 21b and the second coating materials rolling-up mechanism 22b is coated in pressure roller 32.
As shown in fig. 6, traction film 23 is before entering the working clearance, traction film 23 is towards being attached on the end face of battery pole piece
Coating materials 24, after traction film 23 enters the working clearance, coating materials 24 is covered respectively under the extruding of fixing roller 31 and pressure roller 32 in electricity
The both ends of the surface of pond pole piece, and removed from traction film 23.H point in Fig. 6 is overlay film point, is started after battery pole piece to overlay film point
Overlay film.Material conveying mechanism 1 is used for the workplace being sent into material 10 (i.e. battery pole piece) between fixing roller 31 and pressure roller 32
Gap, since the conveying mechanism of material conveying mechanism 1 is conventional techniques in the prior art, specific structure is no longer superfluous herein
It states.
As shown in Figure 1, color mark sensor 6 is fixed on the rack and is electrically connected with second controller (not shown), colour code is passed
Sensor 6 is located at the side in the supplied materials direction of battery pole piece.The laser beam of color mark sensor 6 is perpendicular to battery pole piece, due to battery
The distance for walking line speeds and color mark sensor 6 to overlay film point of pole piece be it is fixed, color mark sensor 6 senses applying area
Signal can be issued when 100 start-stop point, second controller walks line speeds and color mark sensor 6 to overlay film according to battery pole piece
The distance of point can accurately calculate applying area 100 to the time needed for overlay film point, can generally be accurate to millisecond.
Preferably, as shown in connection with fig. 4, nose of cam 421 first turns to D point position, and the starting point for being then left white area 101 arrives
When overlay film point, system controlled further according to the length for being left white area 101 nose of cam 421 from B point position be moved to C point position when
Between, overlay film precision of the final accurate control coating materials 24 in applying area 100.Specifically, second controller is sent out according to color mark sensor 6
After time needed for signal out calculates the start-stop point to overlay film point of applying area 100, calculated further according to the length for being left white area 101
Nose of cam 421 is moved to time s and revolving speed n required for C point position from B point position, while calculating in n revolving speed lower cam
The time s1 needed for from the point position D to B point position of protrusion 421.Then nose of cam 421 is first turned into D point position, works as battery
When the tape transport time that the starting point for being left white area 101 of pole piece goes to apart from overlay film point also needs time s1, then with revolving speed n rotation cam
Axis 42, when being at this moment left white the starting point in area 101 and coming overlay film point, nose of cam 421 is just just rotated into B point position, thus to painting
The accurate overlay film in cloth area 100.
In conclusion implementing a kind of film covering device of the invention, have the advantages that firstly, the application is using convex
Wheel shaft rotates the mode lifted online, and pressure roller is lifted, and makes coating materials is intermittent to be attached on battery pole piece, avoids battery pole
The area that is left white of on piece is pressed overlay film, improves the region of pressure overlay film and the overlapping accuracy of applying area.Secondly, the application utilizes pressure
Force snesor incudes the size exerted pressure, and achievees the purpose that accurately to press to pressure roller by adjusting the pressure of pressure oil cylinder.
Third, fine tuning clearance mechanism are used to adjust the size of working clearance between fixing roller and pressure roller, are suitable for the working clearance not
The battery pole piece of same material and performance improves the qualification rate of product.4th, the supplied materials direction of battery pole piece has one apart from overlay film point
The place of set a distance is fixed with color mark sensor, can accurately control coating materials in the overlay film precision of applying area.
