In one embodiment, the left and right sides of force fit plate 154 is provided with at least two limited posts 157, every limited post 157 Inner side 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 exists It is placed in when not suppressing on limited block 157.In one embodiment, limited post 157 is provided with 4, left about force fit plate 154 Right symmetry, force fit plate 154 sets and is of five storeys, and last layer and basecoat force fit plate need not the support of limited block 157, therefore, limit Position 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 is medium to be pressed；The door-plate 132 of control system control room door 130 falls, close pressing room 110, air extractor start by The inner space of pressing room 110 is evacuated environment；The drive end of the hydraulic cylinder 121 of hydraulic means 120 is started working, and applies one Fixed pressure is under backing plate 152, thus promotes undermost force fit plate 154 to start to extrude treating in the 154b of pressing chamber successively and press The pcb board bag 160 of system, meanwhile, heating assembly is started working, and heats pcb board bag 160 to be pressed, suppressed Pressure size in journey, temperature height, press time are carried out feedback regulation by control system；After having suppressed, heating assembly stops Only work, now, hydraulic means 120 keeps pressure during compacting constant, and cools down assembly and start working, such as can be at force fit plate Conveying pipe 154c in 154 is passed through constant flow, temperature control the conduction liquid between 15 DEG C ~ 35 DEG C, to suppressed Pcb board bag 160 cools down, and this process is carried out feedback regulation by control system, when control system detects that pcb board bag 160 is cold When but arriving design temperature 45 DEG C ~ 65 DEG C, stopping the supply of conduction liquid, hydraulic means 120 starts to be gradually reduced pressure, room door 130 After opening, the pcb board bag 160 suppressed is taken out and wait follow-up processing work.

With reference to Figure 21 and Figure 22, it can be seen that traditional cold press and according to the many cavity layer of cold-hot integrated formula of the present utility model Press 100 compares, same measurement X-Y direction (500 ~ 620mm distance) harmomegathus data, cold-hot integrated formula multi-cavity of the present utility model The product that laminating machine 100 produces, the deflection of upper, middle and lower layer product is almost consistent, and contrast traditional cold press has and obviously changes It is kind, additionally, due to after having colded pressing, the temperature of force fit plate 154 directly drops to the temperature that technique needs, and directly can start next Criticizing and produce, it is not necessary to extra cool time, device efficiency is high, further increases production efficiency.

With reference to Figure 23 and Figure 24, take 350 sheet measurement X-Y direction (500 ~ 620mm distance) harmomegathus data and add up, can To find out, according to cold-hot integrated formula multi-cavity laminating machine 100 of the present utility model compared with traditional cold press, of the present utility model cold Its harmomegathus data of product that hot Integral multi-cavity laminating machine 100 produces substantially are concentrated, the product harmomegathus produced than traditional cold press Rate has reduced 30 ~ 40%.

With reference to Figure 25, Figure 26, Figure 27 and Figure 28, it can be seen that be laminated according to cold-hot integrated formula multi-cavity of the present utility model Machine 100 is compared with traditional cold press, according to the monolithic produced of cold-hot integrated formula multi-cavity laminating machine 100 of the present utility model PCB expansion maximum distortion reduces 40 ~ 50% than what conventional voltage machine produced.

Although embodiment of the present utility model is disclosed as above, but it is not limited in institute in description and embodiment Row use, and it can be applied to various applicable field of the present utility model completely, for those skilled in the art, and can It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this practicality Novel be not limited to specific details and shown here as with describe legend.
