Winding head for lamination stacking machine and working method thereof

Abstract

The invention relates to a winding head for a lamination stacking machine and a working method thereof. At present, membrane winding for a lamination stacking machine has much waste and inaccurate stroke. The winding head comprises a fixed plate which is transversely arranged, left and right winding heads which are symmetrically arranged on the fixed plate, wherein the left and right winding heads comprise clamping mechanisms, rotation mechanisms and moving mechanisms; each moving mechanism comprises a motor for moving, an eccentric part which is driven by the motor for moving, a sliding plate connected with the eccentric part, and a fixed seat which is connected with the slide plate and is used for driving the clamping mechanism to move left and right; a membrane hole is formed at the center of the fixed plate and is used for membrane penetrating; and when the motor for moving rotates, the eccentric part connected with the motor for moving rotates and drives the sliding plate and the fixed seat to move left and right, and the clamping mechanism moves left and right along with the fixed seat. According to the technical scheme, the winding head has quick and accurate action, is favorable to improving the work efficiency, and works reliably.

Description

technical field [0001] The invention relates to a winding head for a laminate machine and a working method thereof. Background technique [0002] Lithium batteries are attracting more and more attention due to their green and environmental advantages. They have the characteristics of high capacity, low consumption, no pollution and many cycles. They have been applied to military and civilian fields such as mobile phones, computers, and cameras. The production process of lithium battery cells can be roughly divided into: lamination, winding and glue sticking. During the winding process, the positive and negative electrodes are separated by zigzag winding separators on the cells. [0003] At present, Z-shaped winding separators often use a winding lamination machine that clamps the battery pole piece with a clamping manipulator and rotates 180 degrees in one direction. The disadvantage is that the diaphragm is wasted, which leads to an increase in the width of the battery afte...

Problems solved by technology

[0003] At present, Z-shaped winding separators often use a winding lamination machine that clamps the battery pole piece with a clamping manipulator and rotates 180 degrees in one direction. The disadvantage is that the diaphragm is much wasted, resulting in an increase in the width of the battery after winding and lamination.

In addition, the displacement of the left and right winding heads is often carried out by means of cylinder displacement. The stroke is not accurate enough, prone to failures, prone to out-of-place strokes, etc., and the speed is slow
