Preheating device before the circuit board film pressing as previously discussed, wherein, this centralized positioning machine is formed side by side and with the roller that rotates in the same way by majority is equidistant, establish on each roller two parallel and can adjust the correction guide plate of spacing, wherein: set up inductor separately between some groups of rollers near the port of export.
Preheating device before the circuit board film pressing as previously discussed, wherein, this centralized positioning machine is provided with a temperature-sensing element in port of export place, and this temperature-sensing element can change the rotating speed of each roller according to this.
As from the foregoing, preheating device is by being provided with the heating element that a pair of copper foil plate of finishing directional correction heats before the printed circuit board (PCB) press mold of the present utility model before the press mold machine of the centralized positioning machine port of export, promptly utilize heating elements such as high frequency or electromagnetic wave after the centralized positioning machine, before the press mold copper foil plate is heated, and can effectively keep its surface temperature, and then help improving the press mold quality.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Fig. 1: be plane graph of the present utility model.
Fig. 2: the vertical view that is the utility model centralized positioning machine.
Fig. 3: the schematic appearance that is the utility model coil.
Fig. 4: the plane graph that is traditional preheating machine.
Fig. 5: the vertical view that is traditional centralized positioning machine.
See also shown in Figure 1, relevant structure division of the present utility model, it mainly is to be provided with a centralized positioning machine 20 in press mold machine 10 front ends, the two is provided with one group of conveying roller 11, to push copper foil plate through overcorrect location and preheating step, be provided with majority again in the centralized positioning machine 20 and be equidistant roller 21 for row, each roller 21 is to be running in the same way, advances towards press mold machine 10 directions to carry copper foil plate.
Please cooperate again and consult shown in Figure 2ly, aforementionedly respectively organize the correction guide plate 22 that roller 21 is provided with two groups of visual actual needs spacings, with the direction of propulsion of correcting copper foil plate; Centralized positioning machine 20 is arranged with inductor 23 in 21 on array roller near the port of export again, and each organizes inductor 23 is in order to detect the propelling movement stroke of copper foil plate, as the basis for estimation of roller 21 whereabouts control.
Be roughly the basic framework of centralized positioning machine 20 with previous constructions, then establish with heating element 30 as for utility model feature of the present utility model, so that the copper foil plate of sending via each roller 21 is heated at the contiguous port of export place of centralized positioning machine 20 inside.
Because heating element 30 is ports of export of being located at centralized positioning machine 20, this place is a beeline with press mold machine 10, is sent to press mold machine 10 after the copper foil plate heating, and its surface temperature still can effectively be kept, to guarantee the pressing quality of dry film and copper foil plate.
And for example before take off describedly, because of centralized positioning machine 20 inside are provided with some inductors 23, it is very responsive for temperature, therefore, in the selection of heating element 30, promptly must this factor of careful consideration.
And be to make the copper foil plate surface of passing through can effectively be heated to proper temperature rapidly, and unlikely inductor 23 and other the thermally sensitive facilities that influences centralized positioning machine 20, the utility model adopts electromagnetic wave or high frequency that the copper foil plate by this coil is heated, because electromagnetic wave or high frequency are only had an effect to the copper foil plate that passes through, can't arround produce heat energy, so unlikely inductor 23 to center localization machine 20 inside impacts.
As for producing high frequency or electromagnetic heating element 30 are as shown in Figure 3 high frequency coils 31, this high frequency coil 31 has two parallel relatively long ends, its length perseverance is greater than the width of copper foil plate, and suitable can passing through therebetween for copper foil plate, two long ends have suitable spacing again, when copper foil plate passes through this high frequency coil 31, the right position is in generation high frequency or electromagnetic induction range, so can produce high frequencies or electromagnetic wave in the copper foil plate surface induction and produce high temperature by high frequency coil 31, known to the reality test, this copper foil plate is by behind high frequency coil 31 induction heating, its surface temperature can reach more than the temperature of processing procedure requirement, after sending, send into press mold machine 10, still can keep its surface temperature really at the needed plate surface temperature of processing procedure by conveying roller 11.
Still see also shown in Figure 1, surface temperature for the immediately monitoring copper foil plate, guarantee its pre-heat effect before press mold, this centralized positioning machine 20 is provided with a temperature-sensing element 24 in the port of export, the copper foil plate surface temperature of utilizing this temperature-sensing element 24 to sense, when the copper foil plate surface temperature is on the low side, will improve the electric current output of power supply to improve firing rate, the shortening demand for heat time.Otherwise, when the copper foil plate surface temperature is higher, then reduce electric current output, to reduce firing rate.
With main very first time after grasping preheating and finishing of preheating device before the aforesaid press mold, copper foil plate is delivered to press mold machine and dry film pressing, to obtain desirable pressing quality, under the prerequisite of guaranteeing the press mold quality, still effectively keep the correction positioning function of centralized positioning machine, because of the combination effect correction effect of preheating device, it is inner set also at all not unaffected as facilities such as inductor, air conditioner surroundings for it.
