Description
Technical Field
The utility model relates to a lithium cell preparation field, concretely relates to high temperature resistant coating PET membrane furring strip mould.
Background
Lithium ion power batteries have been widely used in military and civil small-sized electrical appliances, such as mobile phones, portable computers, video cameras, and the like, because of their advantages of high energy density, high battery voltage, wide operating temperature range, long cycle life, environmental protection, and the like.
With the continuous progress of science and technology, high-capacity power lithium ion batteries have been applied to electric vehicles, and become one of the main power energy sources of electric vehicles in the 21 st century. The rapid development of the new energy automobile industry puts high requirements on the safety, environmental protection, the service performance of large-current charging and discharging and the like of the lithium ion battery. In large-scale production, research shows that the coating process in the manufacture of lithium ion batteries is particularly important in order to improve the performance of the batteries.
When the existing pole piece coating machine head coats sizing agent on an aluminum foil, because a supporting roll, a coating roll and a metering roll are all cylindrical structures, the sizing agent can be coated on the aluminum foil uniformly, the coating width can not be determined according to the width of a battery, in order to solve the problem, a PET (polyethylene terephthalate) stop bar needs to be additionally arranged on the coating roll in the coating process (so as to ensure the size of a gap reserved foil in the middle), the existing processing mode is to cut a triangular stop bar module, the width of the coated dressing is adjusted in a mode of manual left-right movement, but the coating process is difficult to control in the aspect of the consistency of the width of the dressing because of the deviation of the adjustment precision of personnel.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high temperature resistant coating PET membrane furring strip mould has solved the problem of dressing width because of adjusting the too wide or too narrow phenomenon of bad appearance.
Realize the technical scheme of the utility model is that:
the utility model provides a high temperature resistant coating PET membrane pastes strip mould for the coating machine, the coating machine includes frame, coating roll, backing roll and measurement roller, be equipped with PET membrane pastes strip mould on the backing roll, PET membrane pastes strip mould includes arc elasticity snap ring, is equipped with arc mould board on the arc elasticity snap ring inner wall, the equidistant strip hole that is provided with pastes of arc mould board.
The arc-shaped elastic snap ring is arranged on the supporting roller in a buckling mode, and the outer edge of the arc-shaped elastic snap ring is aligned with the outer edge of the supporting roller.
The shape of arc mould board sets up with the backing roll cooperation, and the inner wall and the contact of backing roll outer wall of arc mould board.
The two arc elastic clamping rings are arranged at two ends of the supporting roller.
The arc-shaped die plate is provided with a fixing line, and the fixing line is aligned with the inner edge of the arc-shaped elastic snap ring
The utility model has the advantages that: the utility model discloses with arc snap ring card on the backing roll, the arc mould board and the backing roll laminating that set up on arc snap ring inner wall, with the position in PET membrane according to pasting a hole, fix on the backing roll, owing to paste equidistant setting in a hole, can guarantee that the coating width is unanimous, this method has not only reduced the complicated link of transferring the machine every day, the coating precision after the use has also obtained standard speech unification, the too wide or too narrow phenomenon of dressing width because of adjusting the bad appearance can not appear.
