Description

Use method of oven with purging device and oven
Technical Field
The invention relates to the technical field of use of ovens, in particular to a use method of an oven with a purging device and the oven.
Background
The coating machine is an important production device widely used in the industries of electronics, photovoltaics, printing, textile, leather and the like. The lithium ion battery needs to form a repeated overlapping unit of positive electrode/diaphragm/negative electrode/diaphragm due to the specific structure and characteristics of the lithium ion battery, and the coating process is particularly suitable for manufacturing each layer. Therefore, the coating machine is widely applied to the manufacture of the anode and cathode of the lithium battery and the diaphragm coating. Slurry preparation, coating and drying are three basic steps in the coating process, and the product quality is determined together.
The existing drying process is realized by adopting an oven. During the drying process, the product may partially fall off, forming dust. Particularly, colloidal particles on the separator coating layer may be exfoliated during the separator coating process. The particles fall off from the surface of the diaphragm and are adhered to the oven along with the movement of the air flow in the oven, and particularly, the particles are gathered at the corners of the oven, the air return opening and the like. When the particles are gathered to be bigger, the particles can be scattered around under the driving of the drying airflow in the oven, and the particles can fall onto the surface of the diaphragm to form foreign matters, so that quality defects occur. Furthermore, the colloidal particles are generally sticky, and thus are difficult to remove by conventional methods such as blowing and brushing after being scattered on the membrane.
Foreign matter on the membrane can present two hazards: 1. foreign matters inside the battery can cause the extrusion of the battery in the production and circulation of the battery, and the structure of the battery is damaged. 2. The foreign matter on the diaphragm hinders the lithium ion conduction in the battery, and the problem of lithium precipitation and the like of the battery is caused.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the problem of among the prior art diaphragm in the stoving process, the micelle on the diaphragm coating can drop, falls to the diaphragm surface, causes the diaphragm quality not up to standard is solved. The invention provides a use method of an oven with a blowing device and the oven, which can remove foreign matters on the basis of not damaging a diaphragm and improve the high-quality product rate of the diaphragm.
The technical scheme adopted by the invention for solving the technical problems is as follows: a use method of an oven with a purging device can remove foreign matters adhered to a coated diaphragm in a drying process, and comprises the following steps:
s1, setting the drying temperature in the oven according to the difference of the thickness of the diaphragm, the components of the coating slurry and the coating speed;
s2, drying the coated diaphragm in an oven, and continuously judging whether the diaphragm is in a semi-dry state or not in the drying process;
and S3, when the diaphragm enters the semi-dry state, starting a purging device to purge the surface of the diaphragm.
And the coated diaphragm is in a room temperature state before entering an oven. The temperature in the oven is higher than room temperature. When the membrane enters the oven, heat is conducted from the oven into the membrane, causing the membrane to heat up, the heat of which is proportional to the difference between the oven temperature and the temperature of the membrane. Meanwhile, as the coating layer on the surface of the diaphragm is also provided with a large amount of solvent, the solvent can be quickly volatilized at high temperature to take away heat, so that the diaphragm is cooled, and the cooling heat is in direct proportion to the temperature of the diaphragm.
The membrane has three states in the oven, a wet state, a semi-dry state, and a fully dry state.
Moisture state: the diaphragm coated with the slurry enters an oven, the temperature of the diaphragm is low, the solvent is volatilized to take away less heat, the heat conduction heat is large, the temperature rise heat is larger than the temperature reduction heat, the temperature on the surface of the diaphragm is rapidly raised, and the surface of the diaphragm is wet;
and (3) semi-dry state: the speed of heat conduction absorbed by the diaphragm and the heat taken away by the solvent volatilized from the surface of the diaphragm reach a balanced state, and the temperature of the surface of the diaphragm is kept constant;
the full dry state: after the solvent is basically volatilized, the temperature of the inner core of the diaphragm is raised to the drying temperature of the oven, and the diaphragm is in a full-dry state.
When the semi-dry state is changed into the full-dry state: the volatilization speed of the solvent on the surface of the diaphragm is higher than the speed of the solvent transferred from the inner core of the diaphragm to the surface of the diaphragm, at this time, the dried interface moves downwards to the inner core of the diaphragm, and the diaphragm continues to slowly increase the temperature until reaching the drying temperature, namely, a full-dry state.
The invention judges whether the diaphragm enters the semi-dry state, controls the purging device to purge when the diaphragm is judged to be in the semi-dry state, can remove foreign matters on the diaphragm on the basis of not damaging the diaphragm, and is easy to damage a coating on the surface of the diaphragm and damage the diaphragm if the diaphragm is purged in the wet state.
In step S3, when the difference between the temperature of the surface of the diaphragm and the drying temperature is 10 ℃, the diaphragm enters a semi-dry state. Assuming that the set drying temperature is 60 ℃, the temperature of the surface of the diaphragm continuously rises, and when the temperature of the surface of the diaphragm reaches 50 ℃, the diaphragm enters a semi-dry state, it should be noted that the temperature of the diaphragm continuously rises in the oven, and the highest temperature to which the surface can rise does not exceed the set drying temperature in the oven.
The step S3 further includes: s31, when the difference between the temperature of the surface of the diaphragm and the drying temperature is within 10 ℃, the purging device purges the surface of the diaphragm at a first power.
The step S3 further includes: and S32, when the difference between the temperature of the surface of the diaphragm and the drying temperature is within 5 ℃, the purging device purges the surface of the diaphragm with a second power, and the second power is greater than the first power.
When the diaphragm just enters a semi-dry state, foreign matters on the surface of the diaphragm are easy to blow off, the first power with smaller power can be adopted for blowing, when the diaphragm is in the later stage of the semi-dry state and is close to the fully-dry state, the foreign matters stuck on the surface of the diaphragm are difficult to blow, and the second power with larger power can be adopted for blowing the foreign matters on the surface of the diaphragm.
In the step S2, the temperature sensor is used to measure the temperature of the surface of the diaphragm, the temperature sensor is convenient to obtain materials, simple in structure and convenient to operate,
preferably, in step S3, the purging device is a sonic purging device.
Further comprising the steps of: and S4, stopping the purging by the purging device when the diaphragm is in a full-dry state. In step S4, the separator surface is in a completely dry state when the temperature is the same as the drying temperature.
Optionally, an air outlet is arranged in the oven, the air outlet faces the surface of the diaphragm, and the coated diaphragm is dried by blowing out the air with the drying temperature through the air outlet in the oven.
An oven capable of removing foreign materials adhered to a coated separator during drying, comprising:
the input module is arranged on the oven and used for setting the drying temperature;
the judging module is arranged in the oven and used for judging whether the diaphragm enters a semi-dry state or not;
the purging module is arranged on the surface, facing the diaphragm, in the oven and used for purging the surface of the diaphragm;
and the control module is in signal connection with the input module, the judgment module and the purging module.
The control module can receive the drying temperature set by the input module, control the drying temperature to a set value, receive a judgment result of judging whether the diaphragm enters the semi-dry state or not by the judgment module, control the blowing module to blow according to the obtained judgment result, blow the surface of the diaphragm after the diaphragm enters the semi-dry state, and effectively remove foreign matters on the surface of the diaphragm on the basis of not damaging the diaphragm.
The invention has the beneficial effects that the using method of the oven with the purging device and the oven have the following specific effects:
the invention judges whether the diaphragm enters the semi-dry state, controls the purging device to purge when the diaphragm enters the semi-dry state, can remove foreign matters on the diaphragm on the basis of not damaging the diaphragm, does not start the purging device when the diaphragm does not enter the semi-dry state, and avoids damaging the diaphragm due to damage of a coating on the surface of the diaphragm when the diaphragm is purged in the wet state.
