The method has the characteristics of good reliability, strong practicability and the like.
Description
Technical field
But the utility model relates to the vacuum drying oven of gas moisture in a kind of on-line determination casing, belongs to battery manufacturing equipment technical field.
Background technology
Lithium ion battery is controlled moisture in process of production and is required very strictness, needs the preceding electric core of involutory slurry preceding powder, pole piece and fluid injection to toast usually, and wherein twice baking procedure in back is particularly important.At present, what battery industry mainly adopted is the baking of conventional vacuum baking oven, and basic step is: the intercycle time that suitable baking temperature, stoving time is set and vacuumizes and fill dry gas, after stoving time reaches, finish baking.The method of check cured effect is generally to adopt the karl Fischer moisture teller to carry out determination of moisture.This method all can't avoid sample to contact with external environment in sampling and mensuration process, sample is absorbed water, thereby influence the accuracy of measurement result.In addition, this method length consuming time has prolonged the production cycle.Therefore, industry is not generally measured moisture to roast after baking finishes, and can't judge cured effect thereby cause to toast when finishing, and has brought very big uncertainty to properties of product.In addition, in the battery bake process, baking oven problem such as can leak air once in a while and be difficult in time be found, large quantities of battery flatulence often occur behind this batch battery partial volume, just turnes back to check the problem of baking oven damnous the time.
The utility model content
But the purpose of this utility model is to provide a kind of can be made things convenient in real time, the vacuum drying oven of gas moisture in the on-line determination casing easily.
It states technical scheme: but the vacuum drying oven of gas moisture in a kind of on-line determination casing, comprise the vacuum drying oven and the programmable PLC machine that constitute by casing, heater, vavuum pump and dry gas admission line, it is characterized in that: probe is installed on the cabinet panel of described vacuum drying oven is arranged on the interior moisture transducer of casing.
Compared with prior art, remarkable result of the present utility model is: the moisture transducer that is installed on the vacuum drying oven cabinet panel is connected with the moisture teller of outside, can be online real-time, accurately, measure the actual moisture of gas in the casing easily, for judging that cured effect provides direct basis for estimation, be convenient to adjust baking temperature and time in good time, effectively avoided because of the not enough not good or long problems such as the wasting of resources that cause of stoving time of cured effect that cause of stoving time, and omitted in the existing method baking finish after the step of sampling and testing again, improved production efficiency; In addition, when baking oven breaks down or leaks gas, can in time pinpoint the problems, thereby avoid having improved the qualification rate of product owing to the baking reason causes the underproof problem of typical products in mass production by gas moisture in the casing of on-line determination.Has good reliability, characteristics such as practical.
Description of drawings
But Fig. 1 is the baking oven schematic diagram of gas moisture in the on-line determination casing;
Fig. 2 is a programmable PLC programme-control block diagram.
Specific embodiments
As shown in Figure 1, but the vacuum drying oven of gas moisture in the on-line determination casing comprises the vacuum drying oven and the programmable PLC machine that are made of casing, heater, vavuum pump and dry gas admission line.Probe is installed on casing 1 panel of vacuum drying oven is arranged on the interior moisture transducer 9 of casing.The moisture transducer that is installed on the vacuum drying oven cabinet panel is connected with the moisture teller of outside, can the interior gas moisture of on-line determination casing.
It is the high frequency sensor of 150MHz that moisture transducer adopts wavelength, and the Applicable temperature scope is 0～100 ℃, and measuring range is 2000 ~ 10000 ppm, and certainty of measurement is 1～100 ppm, and the moisture scope that can accurately measure is 0～10000 ppm.
Its moisture measurement process (see figure 2): workpiece is placed in the vacuum drying oven, set baking temperature and vacuum by the programmable PLC machine, the heater that starts in the casing is energized to when setting baking temperature, vavuum pump starts the vacuum that the air in the casing is evacuated to setting, after continuation is baked to the stoving time of setting to workpiece, charge into dry gas again and be baked to the stoving time of setting, loop start vacuumizes and charges into the dry gas step then, reaches until workpiece till the requirement of baking.The time of each on-line moisture determination is arranged on and charges into dry gas and toast distance in 5～15 minutes that set before the stoving time, promptly in 5～15 minutes before next time vacuumizing, moisture transducer is inserted moisture tester carry out on-line testing: the display show value of moisture tester shows when being 10000 ppm that moisture is greater than or equal to 10000 ppm in the casing, the numerical value that display shows then is gas actual water content value in the casing between 0～10000 ppm the time, thereby be real-time, judge that directly cured effect provides foundation, according to the real-time moisture of gas in the casing, adjust baking temperature and the time that is provided with in good time, can effectively avoid causing the long problem such as the wasting of resources that causes of the not good or stoving time of cured effect because of stoving time is not enough.
Claims (2)
1. but the vacuum drying oven of gas moisture in the on-line determination casing, comprise the vacuum drying oven and the programmable PLC machine that constitute by casing, heater, vavuum pump and dry gas admission line, it is characterized in that: probe is installed on the casing of described vacuum drying oven (1) panel is arranged on the interior moisture transducer (2) of casing.
2. but the vacuum drying oven of gas moisture in the on-line determination casing according to claim 1 is characterized in that: it is the sensor of 150MHz that described moisture transducer (2) adopts wavelength.
