Fixed blade monitoring structure and cutting device
This application relates to a fixed blade monitoring structure and a cutting device used for lithium battery manufacturing. The fixed blade monitoring structure includes: an anvil, fixed blade die set, and a fixed blade monitoring assembly. A sliding sleeve is disposed on the anvil. The fixed blade die set includes a fixed blade holder and a fixed blade mounted on the fixed blade holder. An end of the fixed blade holder is slidably mounted in the sliding sleeve. The fixed blade monitoring assembly is mounted in the sliding sleeve and connected to the fixed blade holder, and configured to render status of the fixed blade by monitoring a relative force received by the fixed blade holder. Through the above structure, manpower and time consumption in the tuning process is reduced. The status monitoring of a first cutter and a second cutter can be implemented during the cutting.
1. A fixed blade monitoring structure applied to an electrode plate cutting device, the fixed blade monitoring structure comprising:
an anvil, wherein a sliding sleeve is disposed on the anvil;
a fixed blade die set, comprising a fixed blade holder and a fixed blade mounted on the fixed blade holder, wherein the fixed blade holder is slidably mounted in the sliding sleeve; and
a fixed blade monitoring assembly, mounted in the sliding sleeve and connected to the fixed blade holder, and configured to render status of the fixed blade by monitoring a relative force received by the fixed blade holder, wherein the fixed blade monitoring assembly comprises:
a pressure sensor, one end of the pressure sensor abuts on a flank of the sliding sleeve, and the other end abuts on the fixed blade holder; and
an elastic adjustment portion disposed on an opposite side of the pressure sensor and is configured to elastically connect the fixed blade holder and the anvil, so as to adjust a position of the fixed blade holder in a horizontal direction of the sliding sleeve.
2. The fixed blade monitoring structure according to claim 1 , wherein the elastic adjustment portion comprises a connecting portion and an elastic piece, the connecting portion is parallel to a sliding direction, one end of the connecting portion is threadedly connected to an end of the fixed blade holder, and the other end is elastically connected to the anvil by the elastic piece.
