Deceleration cutting control method and control device

Abstract

The invention discloses a deceleration cutting control method and control device. The deceleration cutting control method comprises the steps that when a product to be cut runs to the preset positionor receives a deceleration signal, the product to be cut is decelerated according to a preset deceleration curve; and when the product to be cut finishes deceleration according to the preset deceleration curve, the product to be cut is cut. The control device comprises a conveying piece, a detection element, a sensor, a controller and a cutting piece. That the product to be cut runs to the presetposition or receives the deceleration signal is adopted as a control signal for decelerating the product to be cut, that is, the product to be cut is decelerated according to the preset deceleration curve as long as any one of the signal that the product to be cut runs to the preset position or the deceleration signal is received is received, and the product to be cut is decelerated according to the preset deceleration curve; and the deceleration curve is preset in advance, so that the preset deceleration curve is flexibly planned, the product to be cut is decelerated according to the deceleration curve, the deceleration time is shortened, and the deceleration efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of cutting control, and in particular, relates to a deceleration cutting control method and a control device. Background technique [0002] In the process of conveying the products to be cut for cutting, it is usually necessary to consider the influence of the running speed of the products to be cut on the cutting accuracy, so as to ensure the cutting quality. For example, in the production process of lithium battery cells, it is usually necessary to use a fully automatic winding machine to make the entire roll of positive and negative electrodes and separators into cells by winding. The main action process of the automatic winding machine includes Loading, pre-rolling, winding of positive and negative electrode sheets and separators, cutting of electrode sheets and separators, changing stations, sticking tapes and cutting materials, etc. During the operation of the automatic winding machine, the ...

Problems solved by technology

During the operation of the automatic winding machine, the operating speed of the positive and negative electrodes is usually uncontrollable, and the operating speed of the positive and negative electrodes directly affects the stability of the operation of the automatic winding machine. When the negative electrode sheet is cut, the cutting accuracy of the electrode sheet will be poor, so that the quality of the wound cell cannot be guaranteed, and the yield rate of the cell will be affected.
