Abstract
The utility model relates to a kind of electronic-grade glass fiber cloth drying oven, comprise the first gas oven, the second gas oven and this plate of henry chloranthus herb, first gas oven and the second gas oven horizontal meaders are arranged or vertical consolidation is arranged, two blocks of gas plates are respectively provided with in each gas furnace wall, and these two blocks of gas plates are staggered relatively, electronic-grade glass fiber cloth by transmission device by its from block gas plate of two in the first gas oven across and between block gas plate of two in the second gas oven.The utility model optimizes stove district structure, simplifies the structure of technique and whole factory building, and makes in-furnace temperature even, and power is low, conveniently controls timely and effectively whole bake out temperature, eliminates the time of high-temperature baking, improves the heat resistance of downstream substrate product.
Description
Technical field
The utility model relates to a kind of drying oven, is applied to the drying oven to heat resistance and the higher electronic-grade glass fiber cloth of dimensional stability requirement in printed circuit copper clad laminate industry specifically.
Background technology
At present when carrying out post processing to the electronic-grade glass fiber cloth after secondary destarch, first electronic-grade glass fiber cloth can be admitted to impregnating groove, it is carried out to the coating of surface conditioning agent, then dried, baked strength and the heat resistance of degree to downstream printed circuit board have a great impact.Because electronic-grade glass fiber cloth is originally as inorganic material, and epoxy resin is organic material, and the existence of surface conditioning agent is exactly to inorganic matter and organic matter be combined closely by coupling reaction better.Control impregnation stove district's bake out temperature and time, avoid the destruction of excessively drying its chemical bond and intensity, thus improve the heat resistance of printed circuit board.
Current normally used drying oven, the stove district design that such as German BRUCKNER company provides.As shown in Figure 1, this existing stove district structure, conventional is install this plate 4 of henry chloranthus herb in a gas oven 2, gas oven 2 cavity temperature can keep very high, and electronic-grade glass fiber cloth shift motion in stove district is short, and baking time is not long, non-uniform temperature, stoving process is very poor.
Because the furnace heat of original natural gas heat supply is uneven, short distance, for this reason, usually also need use steam oven 1 to coordinate a gas oven 2 to use together, the even heat of steam oven, low-temperature bake is shaping.But attracting distinct issues is thus, first factory needs the Cemented filling steam of huge long distance, perishable, need frequent supporting personnel to carry out maintenance and repair, secondly heat radiation is large, thermal losses is strong, energy consumption is very large, and can not meet the requirement of needs flash baking now, and last so operating procedure program is many, service time is long, and steam oven and gas oven temperature contrast are large, inequality of being heated and temperature control is inconvenient.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides a kind of electronic-grade glass fiber cloth drying oven, improves impregnation stove district stoving process, to meet the demand of market to high-fire resistance product.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of electronic-grade glass fiber cloth drying oven, it is characterized in that: comprise the first gas oven, the second gas oven and this plate of henry chloranthus herb, first gas oven and the second gas oven horizontal meaders are arranged or vertical consolidation is arranged, each gas oven inwall is respectively provided with two blocks of gas plates, and these two blocks of gas plates are staggered relatively, electronic-grade glass fiber cloth by transmission device by its from block gas plate of two in the first gas oven across and between block gas plate of two in the second gas oven.
The beneficial effects of the utility model are: optimize stove district structure, simplify the structure of technique and whole factory building, and making in-furnace temperature even, power is low, conveniently controls timely and effectively whole bake out temperature, eliminate the time of high-temperature baking, improve the heat resistance of downstream substrate product.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the drying oven of prior art.
Structural representation when Fig. 2 is the utility model two gas oven horizontally sets.
Fig. 3 is the structural representations of the utility model two gas ovens when longitudinally arranging.
Description of symbols: steam oven 1, first gas oven 2, second gas oven 3, gas plate 4, transmission device 5.
Detailed description of the invention
The tight ness rating of figure bend is directly proportional to the height of temperature, and oblique line is more intensive, and temperature is higher, otherwise oblique line is more sparse, and temperature is lower.
As shown in Figure 2: a kind of electronic-grade glass fiber cloth drying oven, the first gas oven 2, second gas oven 3 and this plate 4 of henry chloranthus herb is comprised;
Embodiment 1: the first gas oven and the second gas oven horizontal meaders are arranged, each gas oven inwall is respectively provided with two blocks of gas plates, and these two blocks of gas plates are staggered relatively, transmission device 5 is roller group, it by electronic-grade glass fiber cloth from block gas plate of two in the first gas oven across and between block gas plate of two in the second gas oven.
Embodiment 2: as shown in Figure 3, first gas oven and the second gas oven vertical consolidation are arranged, each gas oven inwall is respectively provided with two blocks of gas plates, and these two blocks of gas plates are staggered relatively, transmission device 5 by electronic-grade glass fiber cloth from block gas plate of two in the first gas oven across and between block gas plate of two in the second gas oven.
Embodiment 3 (transformation embodiment): the steam oven 1 in existing drying oven stove district (as Fig. 1) is dismantled, the second gas oven 3 is set up in the position of this steam oven 1, this plate of henry chloranthus herb in original gas oven is removed two pieces and is transferred to the second gas oven 3, the gas oven after being removed is considered as the first gas oven 2.Factory improvement project simplifies, but obtain effect and embodiment 1, embodiment 2 is identical, so, social effect and economic implications huge, energy-saving and environmental protection, transform the Jiu Lu district changing the industry and have dissemination.
The present embodiment also can avoid in-furnace temperature too high; Gas plate in first gas oven and the second gas oven is two pieces, and in-furnace temperature is even, and power is low.So, also the structure shown in Fig. 2 can be obtained.
