Description
Technical field
This utility model relates to lithium battery diaphragm production technical field, is specifically related to a kind of barrier film indirect type coating equipment.
Background technology
Battery core is after the PROCESS FOR TREATMENT such as discharge and recharge, and battery core internal electrode can produce expansion, if expanding, cannot stretch will
Causing electrode to distort so that electrode spacing between layers changes, certain position showing as finished product battery core presents
The distortion change of rule, surface irregularity, there is concave-convex sense.This causes battery core surface SEI film to come off and internal micro-short circuit, under performance
Fall, circulation ability is deteriorated.Battery core deformation is made up of internal and external factor, and one of them is core strueture uneven thickness weighing apparatus, barrier film
The extrinsic factor such as shrink, pole piece gap between layers is too small at battery core inner corner, when battery core pole piece expands, electrode layer
Between produce interaction force, show as battery core pressurized in the width direction, on a certain pressurized cross section, internal force is extremely the most uneven, should
Power is concentrated, and produces moment of flexure, causes pole piece to distort, thus cause battery core to deform.For this reason, it may be necessary to the membrane thicknesses to battery core corner
Improve.
Utility model content
This utility model is for the disappearance of prior art existence, it is provided that a kind of membrane thicknesses improving battery core corner is divided
Cloth unbalanced barrier film indirect type coating equipment.
For achieving the above object, this utility model uses such as purgation technical scheme:
A kind of barrier film indirect type coating equipment, the coating material cartridge including frame and being located in frame, feeding deflector roll, deflector roll are installed
Frame and control panel, described coating material cartridge and deflector roll installing rack be respectively arranged on the two ends, left and right of frame, and described feeding deflector roll includes the
One feeding deflector roll and the second feeding deflector roll, described first feeding deflector roll and the second feeding deflector roll are respectively arranged on the upper of deflector roll installing rack
Lower two ends, and it is located towards the side of coating material cartridge, the discharge outlet of described coating material cartridge is provided with for transferring to pass through by coating
The coating roll on barrier film between first feeding deflector roll and the second feeding deflector roll, described frame is provided with coating material cartridge direction and prolongs
The driving element that the guide rail stretched and driving deflector roll installing rack move along guide rail, described driving element communicates to connect with control panel,
And driven deflector roll installing rack to move by control panel control batch (-type).
As a kind of preferred version, described driving element is for driving cylinder.
As a kind of preferred version, also include let off roll and wind-up roll, during work, barrier film from let off roll, warp successively
Wind-up roll rolling is arrived after crossing the second feeding deflector roll and the first feeding deflector roll.
As a kind of preferred version, the barrier film between described first feeding deflector roll and the second feeding deflector roll from bottom to top towards
Tilt away from coating material cartridge direction.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, by frame
Upper setting by driving deflector roll installing rack batch (-type) movable, can make coating intermittence coat along the deflector roll installing rack of guide rail activity
On barrier film, it is achieved that intermittent coating on barrier film, such that it is able to control the barrier film coating in battery core corner as required
Thickness, and then reach to improve internal stress concentration when battery core expands, cause the situation of battery core torsional deformation, improve the peace of battery core
Quan Xing；And, this utility model has only to control, by control panel, the intermittent painting that cylinder activity i.e. may be implemented on barrier film
Cover, simple to operation, be suitable to operated by personnel.
By more clearly illustrating architectural feature of the present utility model, technological means and the specific purposes reached thereof and merit
Can, with specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings:
Accompanying drawing explanation
Fig. 1 is the assembling assumption diagram of the embodiment of this utility model.
Accompanying drawing identifier declaration:
1, coating material cartridge 2, deflector roll installing rack 3, let off roll
4, second feeding deflector roll the 5, first feeding deflector roll 6, wind-up roll
7, coating roll 8, guide rail 9, driving cylinder
10, barrier film
Detailed description of the invention
As it is shown in figure 1, a kind of barrier film indirect type coating equipment, the let off roll 3 including frame and being located in frame, wind-up roll
6, coating material cartridge 1, feeding deflector roll, deflector roll installing rack 2 and control panel, described coating material cartridge 1 is respectively arranged on frame with deflector roll installing rack 2
Two ends, left and right, described feeding deflector roll includes the first feeding deflector roll 5 and the second feeding deflector roll 4, described first feeding deflector roll 5 and
Two feeding deflector rolls 4 are respectively arranged on the two ends up and down of deflector roll installing rack 2, and are located towards the side of coating material cartridge 1, described coating material cartridge
The discharge outlet of 1 is provided with for being transferred to by coating by the barrier film between the first feeding deflector roll 5 and the second feeding deflector roll 4
