Online adjustment monitoring system for line pressure of rolling machine

Abstract

The invention discloses an online adjustment monitoring system for line pressure of a rolling machine. The online adjustment monitoring system comprises a Programmable Logic Controller (PLC) (11), a human-machine interface (HMI) (12), a first pressure transmitter (21), a second pressure transmitter (22), a third pressure transmitter (23), a fourth pressure transmitter (24), a hydraulic station total pressure transmitter (25), a hydraulic station proportional pressure reducing valve (31), an operation skew iron motor (32) and a driving skew iron motor (33). The Programmable Logic Controller (PLC) (11) is connected with the first pressure transmitter (21), the second pressure transmitter (22), the third pressure transmitter (23), the fourth pressure transmitter (24) and the hydraulic stationproportional pressure reducing valve (31) through signal lines. According to the online adjustment monitoring system for the line pressure of the rolling machine, the line pressure in the rolling process can be accurately controlled, the line pressure in the rolling process is constant, and therefore high-quality pole pieces with good thickness consistency and small range can be output.

Description

technical field [0001] The invention relates to the technical field of adjustment and monitoring of line pressure during the rolling process of lithium-ion battery pole coils, in particular to an online adjustment and monitoring system of line pressure of a rolling machine. Background technique [0002] 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, electric In terms of large and medium-sized electric equipment such as bicycles and electric tools, the performance requirements of lithium-ion batteries are getting higher and higher.

Problems solved by technology

[0003] At present, during the rolling process of lithium-ion battery pole coils, the rolling line pressure of the rolling machine cannot be accurately controlled. It is only possible to make rough adjustments by adjusting the pressure of the hydraulic station and the position of the inclined iron, and it is impossible to grasp the line pressure during the actual rolling process. pressure

Therefore, when the line pressure fluctuates greatly, if it cannot be detected in time, it will lead to large fluctuations in thickness and range during the production process of the pole roll. After transferring to the subsequent process, the consistency of the produced battery cannot be guaranteed.
