The entry and intake carrier 200 and the heating tray 3012 are in contact with the press disk in contact with the press disc.
[0036]The vacuum pump unit 4 is connected to the injection warehouse 1, the continuous pressure unsuchang 2, and the discharge bin 3 are connected to provide vacuum conditions inside the corresponding border, and the binding warehouse 1, the continuous pressure unstoptage 2 and the discozon 3 Vacuum status independent control, wherein the continuous pressure unpacking 2 is always in a vacuum state in the working state, the injection bin 1 and the discharge bun 3 are in a vacuum state or a vacuum release state in the operation. The principle of its work is as follows:
[0037] Continuous pressure closing 2 is in a vacuum state in the continuous pressure closing 2; after the injection bin 1 is completed, the vacuum pump unit corresponding to the material warehouse 1 is opened, so that the injection bin 1 is in a vacuum state; the pressure and continuous operation of the injection bin 1 When the pressure is composed, the warehouse between the injection bin 1 and the continuous pressure closure 2 is turned on, and the entry train carrier is delivered to the continuous pressure changing bin 2, while the rear bond widow 1 and continuous pressing The warehouse between the warehouse 2 is closed, and the injection is released in vacuo to wait for the new pressed plate to enter;
[0038] When the pressing assembly 300 is close to the end of the continuous pressure uniform position 2, the vacuum pump unit of the silo is turned on, so that the discharge bin is in a vacuum state; when the pressure of the silo 3 is the pressure and continuous pressure When the pressure is consistent, the warehouse between the discharge bin and the continuous compression coherence is turned on, and the entry train carrier will be transported into the discharge bin, while the warehouse door between the silo and the continuous compression warehouse is closed. The discharge bin releases the vacuum and transfers the press sheet to the next process.
[0039] The display control device is configured to intelligently control the pressing device, such as the working state of the warehouse lifting cylinder 213, the top riser cylinder 215, the pressing hydraulic pressure cylinder 217, and the vacuum pump unit 4.
[0040] Based on the structure of the inner layer plate of the PCB line process, the present invention also provides a high vacuum continuous pressing method of the inner laminate of the PCB line process, which includes the following steps:
[0041] Step S1, the warehouse, the warehouse, the continuous pressure, and the warehouse, and turn on the vacuum pump unit corresponding to the continuous pressure unity, so that the continuous pressure closure is in a vacuum, the vacuum is 0.9 × 10 5 PA-1 × 10 5 PA;
[0042] In step S2, in a state where the injection bin is at the atmospheric pressure, place the strip assembly on the entry into the trainer, and the feed bin is sent to the injection bin, and the feed end of the injection bin is closed, and the press-fit disk sliding contact cable is The transfer carrier and the power contact position of the heating disk in the sheath of the sheath, the heat transfer trail is turned on, and the heat disc is heated to heat the inner plate, and the temperature rise rate is 1-3 ° C / min;
[0043] Step S3, the vacuum pump unit of the injection bin is opened, and the injection bin is in a vacuum state, and the vacuum degree of the injection bin is consistent with the continuous pressure, and the inner layer plate temperature reaches 100-160 ° C, the display control device The warehouse is controlled between the injection bin and the continuous pressure uns, and controls the transfer trolley to move to the continuous pressing position; the warehouse between the post-inbound bin and the continuous pressure uniform is closed, and the injection is released. Waiting for the new pressed plate to enter;
[0044] Step S4, the display control device controls the sequential cold press processing in a continuous plurality of press-fit cells, and the cold pressure time is 55-65 min;
[0045] Specifically, after the pressed plate assembly enters the press unit, the display control device controls the top rising hydraulic cylinder and the compression hydraulic cylinder, and the pressure-fixing plate assembly is refrigerated, and the operation time of each stage of the pressing unit is controlled. To reach the needed press effect. From the first stage press unit to the last primary pressing unit, the required time is a cold pressure time, which is 55-65 min, and the pressure of the cold pressure treatment is 90-110 kg / cm. 2. In the application, the number of stamped units can be adjusted according to the feed speed, so that the pre-stage material enters the instruction, the next stage material is rapidly moving to the next champion body.
[0046] Step S5, open the vacuum pump unit of the discharge bin, so that the discharge bin is in a vacuum state, and when the vacuum degree of the silo is consistent with the continuous pressure uncomfort, the display control device controls the distribution bin and the continuous pressure The warehouse is turned on and controls the transportation of the vehicle to move to the discharge bin;
[0047] Step S6, the warehouse between the discharge bin and the continuous compression warehouse is closed, and the discharge bin releases the vacuum and transfer the press sheet to the next step.
