Description
Technical field
The present invention relates to a kind of cold press, be specifically related to a kind of novel controlled EAT cold press.
Background technology
In existing cold press technology; Have following technological problems: 1. existing cold press basic principle is through blowing on one side; On one side exhausting is come cooling products, above cover clamp (steel plate material) apply the pressure that needs, product generally is cooled to 80 ℃ of end from 180 ℃.Because when beginning to cold pressing, the temperature of product is 180 ℃, and the temperature of generally drying is 25-35 ℃; The temperature difference causes greatly that cooling rate is too fast (generally to reach 1.2-1.7 ℃/minute, but for the wiring board product, in this stage; Hope plate temperature more than 130 ℃ the time, it is more satisfactory being controlled at 0.6-0.9 ℃/minute), just cause thus for some thin plates (below the 0.8mm); Still exist the distortion and the plate bent plate of wiring board plate to stick up problem, necessarily scrap thereby produce.2. when temperature is lower than below 130 ℃, because the temperature difference is more and more littler, cooling rate also will be fallen more and more lowlyer (generally can be lower than 0.5 ℃/minute; But for the wiring board product; In this stage, hope cooling rate be controlled at 1.2-1.5 ℃/minute just passable), just cause the whole production time long thus; The output of cold press and efficient are not high, and whole manufacturing cost is too high.
Summary of the invention
The novel controlled EAT cold press that the object of the present invention is to provide a kind of adjustable EAT, improve the quality of products, reduce solid pollution, reduces cost.
Technical scheme of the present invention is: a kind of novel controlled EAT cold press; The controlled wind-warm syndrome device that comprises the cold press body and be connected with the cold press body; Described controlled wind-warm syndrome device comprises that cold press body top leads to outdoor exhaust duct; The cooling body of cold press body one side, the frequency conversion fan of cooling body opposite side, frequency conversion fan opposite side are provided with a T type pipe; The horizontal other end of T type pipe is connected with the room temperature air inlet, the mouth of pipe of T type pipe top be connected towards outdoor exhaust duct.
In preferred embodiment of the present invention, the centre of said T type pipe and room temperature air inlet is provided with a control valve.
In preferred embodiment of the present invention, the mouth of pipe of said T type pipe top with lead to outdoor exhaust duct in the middle of be provided with a control valve.
According to the invention is a kind of novel controlled EAT cold press, have adjustable cooling rate, thereby the distortion and the plate bent plate that obviously improve the wiring board product sticks up problem; Reducing quality scraps; Thereby reduced solid pollution, the whole production time reduces 15% than traditional cold press, improves cold press efficient; Thereby reduced the manufacturing cost of wiring board, also will reduce the manufacturing cost of whole electronic product.
Description of drawings
Fig. 1 is the structural representation of this novel controlled EAT cold press in novel controlled EAT cold press one preferred embodiment of the present invention;
Each mark is following in the accompanying drawing: 1, cold press body, 2, exhaust duct, 3, cooling body, 4, frequency conversion fan, 5, T type pipe, 6, the room temperature air inlet, 7, control valve.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of novel controlled EAT cold press; Shown in Fig. 1: the controlled wind-warm syndrome device that comprises cold press body 1 and be connected with cold press body 1; Controlled wind-warm syndrome device comprises that cold press body 1 top leads to outdoor exhaust duct 2; The cooling body 3 of cold press body 1 one sides, the frequency conversion fan 4 of cooling body 3 opposite sides, frequency conversion fan 4 opposite sides are provided with a T type pipe 5; The horizontal other end of T type pipe is connected with room temperature air inlet 6, and T type pipe 5 is provided with a control valve 7 with the centre of room temperature air inlet 6.The mouth of pipe of T type pipe 5 tops with lead to outdoor exhaust duct 2 and be connected, the mouth of pipe of T type pipe 5 tops with lead to outdoor exhaust duct 2 centres and be provided with a control valve 7.
When the temperature of the wiring board product in the cold press cavity more than 130 ℃ the time (this temperature can arbitrarily be set according to technological requirement); Close cooling body 3; Close room temperature air inlet 6 control valves 7, open the mouth of pipe and the control valve 7 that leads to outdoor exhaust duct 2 centres of T type pipe 5 tops, blow to the wiring board product to the high temperature wind in the exhausting pipeline (generally reaching 50-70 ℃); And through regulating the speed of frequency conversion fan 4; Reach the desirable cooling rate (being controlled at 0.6-0.9 ℃/minute) that we want, when product temperature is lower than below 130 ℃ (this temperature can arbitrarily be set according to technological requirement), open cooling body 3 condenser pipe systems; Open room temperature air inlet 6 control valves 7; And the mouth of pipe of closing T type pipe 5 tops and the control valve 7 that leads in the middle of the outdoor exhaust duct 2, this moment, EAT generally (can adjust according to technological requirement) about 10 ℃, and the speed through regulating frequency conversion fan 4; Accelerate cooling rate greatly, reach the desirable cooling rate (being controlled at 1.2-1.5 ℃/minute) that we want.
