Description
Technical field
The utility model belongs to copper-clad plate and makes the field, is specifically related to be applied to the cooling device of copper-clad plate industry ultra-thin glass cloth gluing process.
Background technology
Along with the high speed development of electronic technology, the packaging density on the pcb board is increasingly high, and product also is tending towards slimming, lightness; This just requires the PCB substrate to turn to the The thin plate aspect.For multiple-plate slimming, also correspondingly require its central layer copper-clad plate, also slimming of adhesive sheet.No matter be ultra-thin copper-clad plate, or adhesive sheet, all will use ultra-thin adhesive sheet, that is, the gluing prepreg of ultra-thin glass cloth, so, the quality good or not of ultra-thin glass cloth adhesive sheet, play a part aspect the ultra-thin multi-layer sheet very important.
Conventional glass cloth gluing machine generally is to adopt vertical, hot air type and heat radiation type gluing machine, and glass cloth reaches semi-cured state through carrying out oven for drying behind the impregnation.No matter be which kind of gluing machine; All to cool off walk out baking oven after its prepreg is dried in gluing machine before through a sealing gland section and packaged air conditioner; The effect of sealing gland mouth is to prevent that hot blast and extraneous cold wind are scurried mutually in the baking oven; What generally adopt is natural wind, and gas wind district is very short, can not produce very big influence to the prepreg temperature; The effect of packaged air conditioner is lowered the temperature to prepreg, preventing and the adhesion of bottom correction roller, so general in the packaged air conditioner what adopt is low temperature wind.
Shown in Figure 1 is a kind of sketch map of existing cooling device, and it comprises: cool wind box 101, interchanger 102, explosion-proof fan 103, wind filter 104, cold water water intaking valve 105, cold water outlet valve 106.Yet what the cool wind box of conventional art was produced by boasting all is cold wind, and its temperature is the highest also can only to reach normal temperature; When the ultra-thin glass cloth (as: 106,104 types etc.) of gluing during through the cooling zone, cool off too soon, resin shrinks suddenly; Metaboly will appear; Because ultra-thin prepreg rigidity is less, will go out curlingly at the widthwise edges position, this curling one side influence the centering effect of correction machine and causes the discounting of rolling prepreg; On the other hand, can on the adhesive sheet broadwise, cause the unbalanced stress weighing apparatus and influence multiple-plate performance.
Summary of the invention
The utility model purpose is that conventional art is transformed, and the problem that broadwise is curled and shunk when the gluing machine downstream end is cooled off, occurs to solve ultra-thin glass cloth prepreg.
Above-mentioned purpose realizes through following technical scheme: a kind of ultra-thin glass cloth gluing cooling device; Comprise cool wind box, interchanger, explosion-proof fan, wind filter, cold water water intaking valve and cold water outlet valve; The downstream installing explosion-proof fan of wind filter; The downstream installing interchanger of explosion-proof fan, the downstream installing cool wind box of interchanger; It is characterized in that also comprise hot water water intaking valve, proportioning valve and hot water effluent's valve, the cold water water intaking valve is connected proportioning valve with the hot water water intaking valve, proportioning valve and then connect the water inlet end of interchanger, cold water outlet valve and hot water effluent's valve are connected the water side of interchanger respectively.
Above-mentioned ultra-thin glass cloth gluing cooling device also comprises temperature sensor, is arranged between the water inlet end of proportioning valve and interchanger.
The utility model is on the basis of conventional art; Interchanger to cooling device is partly transformed; Make Controllable Temperature, the scalable of interchanger part; Make ultra-thin glass cloth gluing cooling device can blow a cold wind over as required and reach the purpose of fast cooling, also can blowing hot-air reach the purpose of slow cooling.
Description of drawings
Fig. 1 is the organigram of existing glass cloth gluing cooling device.
The organigram of the ultra-thin glass cloth gluing cooling device that Fig. 2 provides for embodiment.
The specific embodiment
The ultra-thin glass cloth gummed cloth flexible type of catching a cold; Main cause is that cooling velocity is too fast; Both made cooling air is closed fully or cooling water is closed, adopted natural wind, and widthwise edges also can occur and curl; This is because self temperature of the relative prepreg of temperature of natural wind also is very low, also can make its cooling velocity too fast.The utility model patent is the cooling wind regime with packaged air conditioner; Make to control the wind regime of temperature into, the wind-warm syndrome degree that packaged air conditioner is produced by boasting is in slave mode, regulates wind-warm syndrome according to actual production and needs; Can blow a cold wind over; Also blowing hot-air slows down the adhesive sheet cooling rate, reaches adhesive sheet not crimping, NA purpose, non-shrinking purpose.
Therefore; In conjunction with shown in Figure 2, the ultra-thin glass cloth gluing cooling device that present embodiment provides comprises: cool wind box 1, interchanger 2, explosion-proof fan 3, wind filter 4, cold water water intaking valve 5, cold water outlet valve 6, hot water water intaking valve 7, proportioning valve 8, hot water effluent's valve 9 and temperature sensor 10.The downstream installing explosion-proof fan 3 of wind filter 4, the downstream installing interchanger 2 of explosion-proof fan 3, the downstream installing cool wind box 1 of interchanger 2.Cold water water intaking valve 5 is connected proportioning valve 8 with hot water water intaking valve 7, the water inlet end of proportioning valve 8 and then connection interchanger 2, and between the water inlet end of proportioning valve 8 and interchanger 2, temperature sensor 10 is set.Cold water outlet valve 6 and hot water effluent's valve 9 are connected the water side of interchanger 2 respectively.
The operation principle of above-mentioned ultra-thin glass cloth gluing cooling device is: when cool wind box 1 needs cold wind, and manual-lock hot water water intaking valve 7, hot water effluent's valve 9 valves, manual unlocking cold water water intaking valve 5, cold water outlet valve 6 valves; At this moment; What lead in the interchanger is cold water, and cold water is got back in the cold water circulatory system and gone after having exchanged, and the wind that comes out is cold wind; And utilize temperature sensor 10 thermometrics, proportioning valve 8 joint cold water flow automatically, thereby controlled the temperature of cold wind.Otherwise, when cool wind box 1 needs hot blast, manual-lock cold water water intaking valve 5, cold water outlet valve 6 valves, manual unlocking hot water water intaking valve 7, hot water effluent's valve 9 valves, and through temperature sensor 10 thermometrics, the proportioning valve 8 automatic temperature of controlling hot blasts.
During actual the use, for thicker gummed cloth, like 7628,7630 cloth, its gummed cloth intensity is bigger, and accumulation of heat is more, is difficult for crimping, is difficult for cooling, generally adopts the cold wind cooling, and water temperature is set in 18 ~ 26 ℃.For thin gummed cloth,,, just need logical hot water for preventing the too fast crimping of gummed cloth cooling as 1080,106,104; Water temperature is set in 40 ~ 50 ℃, and surperficial feel low-grade fever shape behind the gummed cloth process bellows district is advisable for about 30 ~ 40 ℃ like this.
