Description

Technical Field

[0001] The utility model relates to the technical field of pre-pressing devices, in particular to a pre-pressing device for preparing copper clad laminates. Background Art

[0002] Copper clad laminate is also known as substrate. The reinforcing material is impregnated with resin, one or both sides are covered with copper foil, and then hot-pressed to form a plate-like material called copper clad laminate. It is the basic material for PCB and is often called substrate. When it is used in the production of multi-layer boards, it is also called core board. In the preparation process of copper clad laminate, a pre-pressing device is required.

[0003] The current pre-pressing device for preparing copper-clad laminates uses a pre-pressing mechanism. When the pre-pressing device for copper-clad laminates is in use, when the placed copper-clad laminates are pre-pressed back and forth, first, the bottom of the cylinder can be fixedly connected to the upper surface of the connecting plate through the receiving effect of the connecting plate, so that the hydraulic rod fixedly connected to the output shaft of the cylinder can be extended and retracted to a corresponding position according to actual conditions through the power of the cylinder. After reaching the corresponding position, the threaded rod fixedly connected to the output shaft of the motor can be driven by the power of the motor to rotate inside the receiving block. Through the rotation of the threaded rod, the threaded sleeve block threadedly connected to the outer surface of the threaded rod can be moved back and forth.

After the replacement is completed, the pre-pressing device can continue to work. Pre-pressing the copper clad laminate cannot make the pre-pressing device work continuously, which makes the existing pre-pressing device for preparing copper clad laminates have low working efficiency and inconvenient to use.
