In one embodiment, the left and right sides of force fit plate 154 is provided with at least two limited posts 157, the inner side of every limited post 157 is equipped with at least one piece of limited block 157, removes last layer and the force fit plate 154 of basecoat, and remaining force fit plate 154 is placed in when not suppressing on limited block 157.In one embodiment, limited post 157 is provided with 4, symmetrical about force fit plate 154, force fit plate 154 sets and is of five storeys, last layer and basecoat force fit plate need not the support of limited block 157, therefore, limited block 157 is arranged to 3 pieces, supports the force fit plate 154 of middle 3 layers the most successively when not suppressing.
Operation principle: the material such as Figure 20 structure being used for manufacturing pcb board is first carried out composition stacking by workman, is finally assembling to pcb board bag 160 to be pressed as shown in Figure 1；After being completed, pcb board bag 160 to be pressed is put into each pressing chamber 154b medium to be pressed；The door-plate 132 of control system control room door 130 falls, and closes pressing room 110, and air extractor starts to be evacuated the inner space of pressing room 110 environment；The drive end of the hydraulic cylinder 121 of hydraulic means 120 is started working, apply certain pressure under backing plate 152, thus promote undermost force fit plate 154 to start the pcb board bag 160 to be pressed extruding in the 154b of pressing chamber successively, meanwhile, heating assembly is started working, heating pcb board bag 160 to be pressed, the pressure size in pressing process, temperature height, press time are carried out feedback regulation by control system；After having suppressed, heating assembly quits work, now, hydraulic means 120 keeps pressure during compacting constant, and cool down assembly and start working, such as can be passed through constant flow in the conveying pipe 154c in force fit plate 154, temperature controls the conduction liquid between 15 DEG C ~ 35 DEG C, the pcb board bag 160 suppressed is cooled down, this process is carried out feedback regulation by control system, when control system detects that pcb board bag 160 is cooled to design temperature 45 DEG C ~ 65 DEG C, stop the supply of conduction liquid, hydraulic means 120 starts to be gradually reduced pressure, the pcb board bag 160 suppressed is taken out after opening and waits follow-up processing work by room door 130.
With reference to Figure 21 and Figure 22, can be seen that, traditional cold press and the cold-hot integrated formula multi-cavity laminating machine 100 according to the present invention compare, same measurement X-Y direction (500 ~ 620mm distance) harmomegathus data, the product that the cold-hot integrated formula multi-cavity laminating machine 100 of the present invention produces, the deflection of upper, middle and lower layer product is the most consistent, contrast traditional cold press has and obviously improves, in addition, after having colded pressing, the temperature of force fit plate 154 directly drops to the temperature that technique needs, directly can start next group to produce, need not extra cool time, device efficiency is high, further increase production efficiency.
With reference to Figure 23 and Figure 24, take 350 sheet measurement X-Y direction (500 ~ 620mm distance) harmomegathus data to add up, can be seen that, cold-hot integrated formula multi-cavity laminating machine 100 according to the present invention is compared with traditional cold press, its harmomegathus data of product that the cold-hot integrated formula multi-cavity laminating machine 100 of the present invention produces substantially are concentrated, and the product harmomegathus rate produced than traditional cold press has reduced 30 ~ 40%.
With reference to Figure 25, Figure 26, Figure 27 and Figure 28, can be seen that, cold-hot integrated formula multi-cavity laminating machine 100 according to the present invention, compared with traditional cold press, reduces 40 ~ 50% according to the monolithic PCB expansion maximum distortion produced of the cold-hot integrated formula multi-cavity laminating machine 100 of the present invention than what conventional voltage machine produced.
Although embodiment of the present invention are disclosed as above, but it is not limited in description and embodiment listed utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, it is easily achieved other amendment, therefore, under the general concept limited without departing substantially from claim and equivalency range, the present invention is not limited to specific details and shown here as the legend with description.
