Description
Technical field
The utility model belongs to lithium ion battery separator production equipment technical field, relates to a kind of drying unit of lithium ion battery separator coating process.
Background technology
In order to improve some characteristic of lithium ion battery separator, coating process can be used to be coated with the very thin aluminium oxide of one deck at membrane surface.Need after coating dry, conventional furnace drying method be barrier film through baking oven, pass through hot-air seasoning.Lithium-ion membrane coating is adopt one side coating at present, baking oven adopts horizontal drying oven, the drawback of hot-air oven furnace drying method is: because hot-air density is little, preferentially can be raised to the top of baking oven, ensure upper and lower homogeneous temperature, hot-air must be made fully to flow mixing, so enough wind speed must be had, the too little temperature of wind speed is too low, can not dry; Wind speed is too large, can make barrier film double swerve, change the uniformity of coating fluid distribution, and barrier film can be subject to the effect of wind-force, easily occurs deformation.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises a kind of drying unit of lithium ion battery separator coating process, heat directly by infrared lamp conduct radiation on barrier film, avoid too large or too little the caused drawback of wind speed.
The concrete technical scheme that the utility model is taked is: a kind of drying unit of lithium ion battery separator coating process, comprise baking oven, one end of baking oven offers import, the corresponding other end of baking oven offers outlet, barrier film is successively through apparatus for coating, the import of baking oven, the outlet of baking oven, key is: described baking oven is vertical drying oven, the import of baking oven is positioned at below, the outlet of baking oven is positioned at top, barrier film is vertically arranged in baking oven, two infrared lamp groups are set up in baking oven, each infrared lamp group comprises multiple being horizontally disposed with and the infrared lamp be fixedly connected with baking oven, all infrared lamps of each infrared lamp group vertically equidistantly arrange, all infrared lamps of two infrared lamp groups are arranged in barrier film bilateral symmetry.
Be connected in parallel between all infrared lamps.
Spacing in described each infrared lamp group between adjacent two infrared lamps is 10 ~ 15cm.
The model of described infrared lamp is 1100*15mm, middle-infrared band, 1.5kW.
The beneficial effects of the utility model are: utilize infrared lamp to heat to barrier film, heat directly by infrared lamp conduct radiation on barrier film, can not can not dry because the too little temperature of wind speed is too low, also barrier film double swerve can not be made because wind speed is too large, the uniformity that can effectively avoid coating fluid to distribute is changed, and barrier film also can be avoided to be subject to the effect of wind-force and to be out of shape simultaneously.And local temperature can regulate by regulating the size of current of correspondence position infrared lamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 represents baking oven, and 2 represent infrared lamp, and 3 represent barrier film, and 4 represent apparatus for coating.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 1, a kind of drying unit of lithium ion battery separator coating process, comprise baking oven 1, one end of baking oven 1 offers import, the corresponding other end of baking oven 1 offers outlet, barrier film 3 is successively through apparatus for coating 4, the import of baking oven 1, the outlet of baking oven 1, described baking oven 1 is vertical drying oven, the import of baking oven 1 is positioned at below, the outlet of baking oven 1 is positioned at top, barrier film 3 is vertically arranged in baking oven 1, two infrared lamp groups are set up in baking oven 1, each infrared lamp group comprises multiple being horizontally disposed with and the infrared lamp 2 be fixedly connected with baking oven 1, the length of infrared lamp 2 is 1100mm, caliber is 15mm, middle-infrared band, power is 1.5kW, all infrared lamps 2 of each infrared lamp group vertically equidistantly arrange, spacing is 10 ~ 15cm, all infrared lamps 2 of two infrared lamp groups are arranged in barrier film 3 bilateral symmetry.
In order to realize the adjustment of local temperature, be connected in parallel between all infrared lamps 2, like this can by the adjustment regulating the size of current of correspondence position infrared lamp to carry out local temperature.
The utility model is in the specific implementation: the direct conduct radiation of the heat that infrared lamp 2 produces is on barrier film 3, can not can not dry because the too little temperature of wind speed is too low, also barrier film 3 double swerve can not be made because wind speed is too large, the uniformity that can effectively avoid coating fluid to distribute is changed, and barrier film 3 also can be avoided to be subject to the effect of wind-force and to be out of shape simultaneously.When needing to regulate local temperature, as long as regulate the size of current of correspondence position infrared lamp 2, structure is simple, convenient to operation.
