Abstract
The invention discloses a process for controlling the density of a coating production surface of a battery pole piece. The process comprises the following steps of firstly coating a battery pole piece with slurry; directly moving the coated battery pole piece to a die-cutting step through a winding shaft so as to be die cut through an automatic die-cutting machine; weighing and sorting the die-cut battery pole piece through a sorting machine, feeding the processed information to a coating procedure control system; adjusting the coating quantity of a coating machine by the coating procedure control system so as to adjust the density parameter of the coating surface of the battery pole piece. By canceling an X-ray thickness measuring instrument on the coating machine, the expense for protecting the occupational health of employees can be reduced; the procurement cost of the equipment can be saved by saving the thickness measuring instrument; by integrating the coating step and the die-cutting step, the production efficiency can be effectively improved, and the product quality control cost can be saved.
Description
Technical field
The present invention relates generally to a kind of battery pole piece coating production surface density and controls technique.
Background technology
Existing production surface density test mode, the density stabilized property of coated face is poor, and production efficiency is low.General coating machine is provided with X-ray thickness gauge, and X-ray measurement instrument purchase cost is high on the one hand, has increased the expense of company aspect the protection of employee's occupational health simultaneously, has indirectly improved production cost.
Summary of the invention
The object of the invention is exactly in order to make up the defect of prior art, provides a kind of battery pole piece coating production surface density to control technique.
The present invention is achieved by the following technical solutions:
Battery pole piece coating production surface density is controlled a technique, specifically comprises the following steps:
(1), battery pole piece being carried out to slurry coating processes;
(2), coating after battery pole piece by Scroll, directly circulate to cross cutting operation, by automatic die cutter, carry out cross cutting;
(3), battery pole piece, by the separator sorting of weighing, utilizes and on computer, extracts sorting weight change information and show the weight curve of cyclical fluctuations after cross cutting;
(4) if show, this curve of cyclical fluctuations exceeds processing range, and signal of telecommunication of system feedback is to painting process control system;
(5), painting process control system is according to changes in weight and convert this variation to surface density data inputs coating machine and control software, automatically regulates coating machine coated weight, and then regulating cell pole coating surface density parameter.
Advantage of the present invention is:
The present invention changes existing production surface density test mode, improves the density stabilized property of coated face, and concrete advantage performance is as follows:
1. cancel the X-ray thickness gauge on coating machine, the expense of reduction company aspect the protection of employee's occupational health;
2. cancel calibrator and can save company's equipment purchase cost;
3. the integrated production of coating and cross cutting operation, can effectively enhance productivity, and saves control of product quality cost.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
The specific embodiment
As shown in Figure 1, a kind of battery pole piece coating production surface density is controlled technique, specifically comprises the following steps:
(1), battery pole piece being carried out to slurry coating processes;
(2), coating after battery pole piece by Scroll, directly circulate to cross cutting operation, by automatic die cutter, carry out cross cutting;
(3), battery pole piece, by the separator sorting of weighing, utilizes and on computer, extracts sorting weight change information and show the weight curve of cyclical fluctuations after cross cutting;
(4) if show, this curve of cyclical fluctuations exceeds processing range, and signal of telecommunication of system feedback is to painting process control system;
(5), painting process control system is according to changes in weight and convert this variation to surface density data inputs coating machine and control software, automatically regulates coating machine coated weight, and then regulating cell pole coating surface density parameter.
