Embodiment approach

[0049] As an embodiment of the present invention, a motor is provided on one side of the mounting base 53, and a first blade 54 and a second blade 55 are symmetrically arranged on the outer ring of the motor shaft; the first blade 54 passes through a guide post Installed on the outer ring of the rotating shaft, the second blade 55 is installed on the outer ring of the rotating shaft through another guide post, and the first blade 54 and the second blade 55 can move along the normal direction of the outer ring of the rotating shaft. When the motor rotates, the first blade 54 and the second blade 55 move outwards along the normal direction of the outer ring of the rotating shaft under the action of centrifugal force. By controlling the motor speed, the displacement of the first blade 54 and the second blade 55 can be controlled, thereby Control the cutting depth of the polar plate to achieve the purpose of scoring on one side and cutting off the other side, reducing the amount of...

Abstract

The invention belongs to the technical field of lithium batteries, and in particular, relates to a lithium battery production process; the process adopts a slitter; the slitter comprises a worktable and a shearing mechanism, and the shearing mechanism comprises a preliminary shearing unit and a re-shearing unit; the preliminary shearing unit is arranged in the middle of the worktable, comprises alower support plate, a lower press plate and a cutting assembly and is used for nicking a polar plate; the re-shearing unit is arranged on one side of the preliminary shearing unit and is arranged onthe worktable; the re-shearing unit comprises an upper support plate, an upper press plate and a cutting assembly; the re-shearing unit is used for cutting off the polar plate; the bottom of the upperpress plate is provided with a groove notch, and the groove notch is internally provided with an adjusting unit; the adjusting unit comprises a left sliding block, a right sliding block and a lead screw. A way of nicking one face of the polar plate and then cutting off from the other face of the polar plate is adopted, the shearing deformation quantity of the polar plate is reduced, the quality of the polar plate slices is improved, subsequent winding slice leakage of the polar plate is avoided, and the internal short circuit caused by the contact between a positive electrode and a negative electrode is avoided.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a lithium battery production process. Background technique [0002] Polymer lithium-ion batteries are very commonly used batteries at present. At present, the research and production of polymer lithium-ion batteries have made significant progress, and their applications in various fields are becoming more and more extensive. In recent years, polymer lithium-ion batteries are the preferred batteries for mobile electronic devices such as mobile phones. [0003] With the widespread use of polymer lithium-ion batteries, there are more and more fields that require polymer lithium-ion batteries, which requires the production of more and more polymer lithium-ion batteries to meet the needs of use. The existing plate slitting process uses a plate shearing machine to cut the plate, but the size of the plate cut out by the current plate shearing machine is very easy to produce a...
