[specific embodiment]
Embodiment one
As shown in Figure 2; A kind of gumming device that is used to prepare copper-clad plate that present embodiment provides; Comprise an interconnective boiler 1 and first water pump 2; Be provided with one between the backwater end of the water side of first water pump 2 and boiler 1 from current return circuit, a chuck viscosity still temperature control path and a chuck glue groove temperature control path, a chuck viscosity still temperature control path comprises interconnective one first proportioning valve 3 and chuck viscosity still 4, and one first temperature control sensor 5 and an agitator 401 are arranged in the chuck viscosity still 4; Chuck glue groove temperature control path comprises interconnective one second proportioning valve 6 and chuck glue groove 7, and one second temperature control sensor 8 is arranged in the chuck glue groove 7; Be provided with a glue conveying box 21 between chuck viscosity still 4 and the chuck glue groove 7, glue conveying box 21 is provided with the switch 22 of a control flow; First water pump 2, first proportioning valve 3, first temperature control sensor 5, second proportioning valve 6, second temperature control sensor 8 and switch 22 are connected controllers (not shown) jointly.
In the present embodiment; First proportioning valve 3 is the threeway proportioning valve; The water side of first water pump 2 is communicated with the water inlet end of first proportioning valve 3; The corresponding respectively water inlet end and the backwater end of boiler 1 that is communicated with chuck viscosity stills 4 in two water sides of first proportioning valve 3, promptly from current return circuit utilize the water inlet end of first proportioning valve 3 and a water outlet wherein bring in connection first water pump 2 water side and boiler 1 the backwater end and form (certain, also can; First proportioning valve 3 can directly communicate through a siphunculus between the backwater end of the water side of first water pump 2 and boiler 1 for one or two logical proportioning valves); Second proportioning valve 6 is two logical proportioning valves.Setting from current return circuit is in order to reduce the number of times out of service of first water pump 2.
The utilization of this gumming device is following:
2 runnings of first water pump, hot water is flowing in current return circuit; Epoxy resin solution ceaselessly adds in the chuck viscosity still 4 and stirs; Then; The temperature value that first temperature control sensor 5 detects resin solutions to be passing to controller, and controller is controlled first proportioning valve 3 according to this temperature value switching value flows to the flow of chuck viscosity still 4 with control hot water, when just beginning; This temperature value is to be lower than a preset value 35 degree; The switching value that controller is controlled first proportioning valve 3 is for flowing to the hot water flow of chuck viscosity still 4 greatly with increasing, when the temperature value of resin solution moves closer to preset value 35 degree, the switching value of first proportioning valve 3 reduces to reduce to flow to the hot water flow that chuck mixes glue still 4 gradually; When the temperature value of resin solution is higher than another preset value 45 degree, first proportioning valve 3 cuts out corresponding water side; Resin solution after the heating, is opened switch 22 in the mixed glue still 4 of chuck, resin solution flows in the chuck glue groove 7 through siphunculus 21; Glass fabric moves immersion in chuck glue groove 7, because the temperature of glass fabric is low, the temperature that can make the resin solution in the chuck glue groove 7 reduces and reduces it and soak into ability; Therefore; The temperature that second temperature control sensor 8 detects resin solution is lower than a preset value 35 when spending, and controller is controlled the switching value of second proportioning valve 6 for big, flows to the hot water flow of chuck glue groove 7 with increasing; When the temperature value of resin solution is higher than another preset value 45 degree, second proportioning valve 6 cuts out.
Owing to the rising of the viscosity with temperature of epoxy resin adhesive liquid reduces, through overtesting, the viscosity of epoxy resin adhesive liquid is in the time of 35-45 ℃, and its viscosity is relatively stable; This gumming device utilizes this principle to come resin solution is heated and constant temperature exactly; Make its viscosity reduction and stable; Make epoxy resin adhesive liquid strengthen, thereby reduce the use amount of organic solvent or need not add organic solvent that this not only can improve the reliability of copper-clad plate to the impregnability of glass fabric; Can also reduce pollution, cut down the consumption of energy, reach the purpose that environmental protection is produced.
For the temperature that lets chuck mix glue still 4 and chuck glue groove 7 is controlled well; The coolant-temperature gage of boiler remains on 55-70 ℃ better; Boiler is provided with a hot water water inlet end 101, a cold water water inlet end 102 and an overfall 103; The hot water water inlet end 101 of boiler 1 and cold water water inlet end 102 correspondence respectively are provided with the 3rd proportioning valve 9, the 4th proportioning valve 10; Be provided with the 3rd temperature control sensor 11 that is connected with controller in the boiler 1, controller is controlled the 3rd proportioning valve 9 and the 4th proportioning valve 10, the three proportioning valves 9 and the 4th proportioning valve 10 and is two logical proportioning valves.
Maintenance for ease, the backwater end of boiler 1 is provided with one first switch valve 12.
In the present embodiment, resin solution from the mode that chuck viscosity still 4 flows to chuck glue groove 7 is: chuck viscosity still 4 places chuck glue groove 7 tops, opens switch 22 through controller, and resin solution relies on gravity to flow in the chuck glue groove 7.Certainly switch 22 can be arranged to the switch of manual control mode, and does not need controller control; Or, a liquid pump gives chuck glue groove 7 with the gum-solution of chuck viscosity still 4 through being set.
Embodiment two
The thinking of present embodiment is to let glass fabric get into chuck glue groove 7 carry out being heated earlier to increase the impregnability of glass fabric before the impregnation; Therefore, present embodiment also comprises a pre-heating device on the basis of embodiment one; As shown in Figure 3; This pre-heating device specifically comprises a baking oven 13 and two glass fabric warm-up mills 14,15 that are provided with up and down; This baking oven 10 is horizontal deep fat heat radiation type baking ovens, and this glass fabric warm-up mill 14,15 is the deep fat warm-up mill, and diameter is 200mm.
Because the temperature of glass fabric is high; Can give the resin solution heating of chuck glue groove 7 and cause resin solution to heat up; Therefore, as shown in Figure 4, gumming device comprises that also one of connection successively is provided with cold water storage cistern 16, one second water pump 17 and a second switch valve 18 of water inlet end 162 and spilling water end 161; The water inlet end 162 of cold water storage cistern 16 is provided with one the 3rd switch valve 163; The water side of second switch valve 18 is communicated with the water inlet end of chuck glue groove 7, and the water side of chuck glue groove 7 is communicated with the backwater end of boiler 1 and the backwater end of cold water storage cistern respectively through a threeway proportioning valve 19, and second water pump 17, second switch valve 18 all are connected with controller with threeway proportioning valve 19; Too high when the resin solution temperature, second proportioning valve 6 cuts out, 17 runnings of second water pump, and second switch valve 18 is opened, and the water side of chuck glue groove 7 is communicated with the backwater end of cold water storage cistern.
