Abstract
The utility model provides a continuous-imidization oven capable of automatically switching membrane penetrating ways and used for copper foil coated with polyimide. The continuous-imidization oven capable of automatically switching the membrane penetrating ways and used for the copper foil coated with the polyimide comprises a box body, a plurality of fixed guide rollers and a plurality of moving guide rollers, wherein a containing cavity is arranged in the box body, the plurality of the fixed guide rollers are contained in the containing cavity, and the plurality of the moving guide rollers are arranged among the fixed guide rollers at intervals and can move up and down relative to the fixed guide rollers. According to the continuous-imidization oven capable of automatically switching the membrane penetrating ways and used for the copper foil coated with the polyimide, due to the fact that the fixed guide rollers and the moving guide rollers capable of moving up and down are arranged in the containing cavity, under the condition of high temperature, the oven can be used with a floating membrane penetrating way or a thousand-winding membrane penetrating way switched. Due to the fact that far infrared is high in heating intensity and has penetrability, the far infrared is used for heating of the oven. Solvent can be thoroughly volatilized. One the other hand, when the imidization in the thousand-winding way is used, through the support of guide rollers and a tensile force effect, material is closely attached to a roller barrel under the counter-acting force effect of the guide rollers, and the material can be effectively prevented from being crimped.
Description
Technical field
The utility model relates to a kind of device that makes metal foil coated continuous imidization, relates in particular to a kind of coating polyimide Copper Foil of wearing the film mode of automaticallying switch with continuous imidization baking oven
Background technology
Flexible printed-circuit board has been widely used in the consumption electronic products such as notebook computer, mobile phone, personal digital assistant and digital camera, because improving constantly of electron trade specification requirement, it is compact that consumption electronic products move towards just fast, day by day requires corresponding flexibility coat copper plate lighter and thinner and have high-fire resistance and a high reliability.Thereby two-layer method flexibility coat copper plate since adopt mechanical property, electrical property and heat resistance all very good polyimide resin obtained fast development in recent years.
Flex circuit application extensively is employed owing to compactization of electronic product, and the production method of flexibility coat copper plate is a lot, and the rubbing method production of at present industry employing is the most general.Produce the rear curing apparatus of flexible coated polyimide metal foil plate for rubbing method, the rear curing apparatus of especially two-layer flexible thermoplastic polyimides clad with metal foil, for example, can adopt single vertical nitrogen oven in batches the flexible polyimides metal clad board of rubbing method to be carried out rear curing, this kind method equipment investment cost is low and by the industry extensive use, but rolling curing easily causes inside and outside volume performance quality variant, and product is frivolous, the loose winding operation easier is very large, owing to using the method to increase the multistep operation, make yield rate lower simultaneously.For example adopt again heated nitrogen continous way baking oven, material carries out continuous imidization by continuous drying tunnel.Also there is defective in this kind method, continous way heated nitrogen baking oven is owing to being heated to inner by table the material that passes baking oven, film surface is easily dried first to become the volatilization that affects the film internal solvent behind the dry film, on the other hand since film to cross baking oven be suspended state, solvent evaporates in the film and material imidization are shunk, do not having to cause easily under the tension force control that material is curling in the broadwise generation, thereby affecting rolling or final use of product; And because when heating conducts heat by heated air, and the EGT of discharge is very high, and the heat of taking away is also very large, need very large heat supplement, consume energy larger.Adopt the continuous baking oven of Far-infrared Heating then can overcome the above problems well.
The continuous baking oven of Far-infrared Heating has two kinds to wear the film mode: the parallel floating film and thousand of wearing is around wearing film.The former is applicable to the product that the polyimides mask has the sticking stickiness of high temperature, and the latter is applicable to the product that the polyimides face does not have the sticking stickiness of high temperature, and the effect with significant inhibition warpage.But this baking oven switches another kind of when wearing the product of film mode after having produced a kind of product of wearing the film mode, can't automatically switch, and each switching all must be lowered the temperature to shut down and again be worn film; Greatly waste energy and the time; Especially be higher than under 300 ℃ the high temperature, the energy and waste of time are even more serious.When the continuous imidization of polyimides, can't efficiently carry out rapidly two kinds of automatic switchovers of wearing the film mode is a large shortcoming of continuous imidization Far-infrared Heating baking oven.
The utility model content
The purpose of this utility model is to provide a kind of coating polyimide Copper Foil of wearing the film mode of automaticallying switch with continuous imidization baking oven, can be fast wear between the film mode and change around wearing two kinds of films at the parallel floating film and thousand of wearing, reduced and worn the time waste of film mode when changing, increased work efficiency.
For achieving the above object, the utility model provides the coating polyimide Copper Foil of wearing the film mode of can automaticallying switch with continuous imidization baking oven, comprise: in be provided with accommodating cavity casing, be contained in several stationary guide rollers in this accommodating cavity and be arranged at intervals between those stationary guide rollers several and move deflector roll, the relative stationary guide roller of described mobile deflector roll can move up and down.
