Problems solved by technology

However, due to the limitation of the existing automatic edge alignment (EPC) deviation correction function, after each rewinding, the battery pole pieces at the original unwinding position cannot be collected completely, and the displacement of the battery pole pieces and the tension will not be corrected. Stability, pole piece wrinkling and other phenomena, i

Abstract

The invention discloses a novel deviation rectifying device of a battery pole piece slurry coating machine. The novel deviation rectifying device comprises a first deviation rectifying sensor (1) anda second deviation rectifying sensor (2), wherein the first deviation rectifying sensor (1) and the second deviation rectifying sensor (2) are respectively located at left and right sides of a batterypole piece foil (3) which is conveyed in the longitudinal direction; a first deviation rectifying controller (4) is connected with the first deviation rectifying sensor (1); a second deviation rectifying controller (5) is connected with the second deviation rectifying sensor (2); a central control unit (6) is connected with the first deviation rectifying controller (4) and the second deviation rectifying controller (5) respectively; a servo motor (7) is connected with the first deviation rectifying controller (4) and the second deviation rectifying controller (5) respectively. The novel deviation rectifying device can be used for carrying out automatic deviation rectification on a battery pole piece in a rewinding process; the winding precision in the rewinding process can be ensured anddisplacement deviation of the battery pole piece is avoided, so that a wrinkling problem of the battery pole piece is avoided.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel deviation correcting device of a battery pole piece slurry coating machine. Background technique [0002] At present, lithium-ion batteries have the advantages of high voltage, high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptop computers, but also widely used in electric vehicles. In terms of large and medium-sized electric equipment such as electric bicycles and electric tools, the safety requirements for lithium-ion batteries are getting higher and higher. [0003] In the production process of lithium-ion batteries, the slurry coating process of battery pole pieces is the bottleneck of the entire lithium battery manufacturing, and the quality monitoring of the slurry coating process of battery pole pieces is particularly important. With the impr...
