1, cylindrical lithium ion battery diaphragm and conical cylindrical lithium ion battery diaphragm and conical ingredients: (1) Roll needle is not concentric; (2) The roll needle is not perpendicular to the substrate; (3) up and down diaphragm final transition roller Not perpendicular to the substrate; (4) the roller and roller are not parallel; (5) The separator is unqualified. Cylindrical lithium-ion battery diaphragm and tapered repair method: (1) use accuracy error at 10.5, 4 * 100 round car steel and roll needle set equal to the concentricity; (2) concentricity After the measurement is completed, measure the verticality of the roller and the large plate with the vertical amount of the measurement (at least the vertical direction to ensure the vertical direction); (3) calibrate the verticality of the last transition roller of the upper and lower diaphragm; If the roller is not perpendicular to the substrate, it can be placed until vertical, and hit the mark; Note: It is not necessary to add a pad) (4) The screw of the first loose rubber roller and the stainless steel roller will be parallel and vertical.

On the substrate, then lock; (5) Replace the separator. 2, the cylindrical lithium-ion battery processing polar displacement and cone failure original (1) roll needle is not concentric; (2) The needle and the substrate are not perpendicular; (3) polar guides and substrates are not vertical and parallel; (4) The final transition roller over the extreme piece is not perpendicular to the substrate; (5) the foot is too serious. Maintenance Measures (1) Use precision error at 10 um 3.

5, 4 * 100 Circular steel and roll needle sets of concentricity; (2) After the same measurement is completed, use the measured vertical gauge and right angles. Measure the verticality of the roller and the large plate (at least to ensure the vertical direction of the two directions); (3) guarantee the verticality of the polar guide and the substrate; (4) Calibrate the final transition roller with a right angle foot Verticalness; (if the roller is not perpendicular to the substrate, you can add the pad until vertical, and hit the mark;. 3, cylindrical lithium-ion battery processing rubber adverse failure original from (1) stickers to Zou; (2) missing stickers; (3) tape transition sticks are not flexible; repair method (1) When the adhesive plate screws When you get rid of a point, try to get it in the center of the battery; (2) First check the sticker and the battery cell is not close, the compact tape adjustment board is loose, the blanket guide wheel is not too high, cylinder The air pressure is not stable, the cylinder adjustment distance screw is loose, the upper clamp wheel is not a compressing tape; (3) the wheel with the front of the adhesive mechanism collide with the lower support, occasionally can't stick in the volume, and support it when collision It is possible to get flexible, and it can't be pressed in the past, so it will cause occasional sticking; (4) Check the one-way bearings of the transition stick, the lock, the lock cover of the transition, adjust the transition stick.

4, cylindrical lithium-ion battery processing pole, diaphragm final displacement failure is caused by the high and low in the support wheel under (1); (2) The polar guide plate and the substrate are not vertical and parallel; repair method (1) first check the battery If the end is off, this phenomenon is too high, so the inside or the outer surface is lowered or hit, and the end of the electrical core is parallel; (2) guarantee the verticality and parallelism of the polar guide and the substrate Spend;.
