Description

Technical Field

[0001] The utility model relates to the technical field of copper clad laminate production, in particular to a glue mixing device for preparing copper clad laminates. Background Art

[0002] Copper clad laminate, also known as substrate, is a plate-like material made by impregnating reinforcing material with resin, covering one or both sides with copper foil, and hot pressing. It is called copper clad laminate. It is the basic material for PCB and is often called substrate.

[0003] In the current glue mixing device for preparing copper clad laminates, after the glue is stirred, the glue enters the delivery pipe through the discharge pipe, and is delivered to the roller shaft in equal amounts in conjunction with the valve. When the telescopic cylinder retracts, it drives the glass fiber cloth to move, and then drives the two roller shafts to rotate. The glue is squeezed out through the extrusion head and smeared on the glass fiber cloth. After the glue mixing is completed, the glue is directly applied, which improves the glue quality and the glue mixing effect of the device. However, the existing bathroom racks still have certain problems, which brings certain inconveniences to the use of the bathroom racks.

[0004] However, in actual use of the existing glue mixing device for preparing copper clad laminates, it is found that the prior art combines a glue mixing structure with a glue coating structure, and can directly apply glue after the glue mixing is completed, thereby improving the quality of the glue and the glue mixing effect of the device. However, if the glue is directly applied after the glue mixing is completed, after the glue is used, it is necessary to wait for the glue mixing structure to complete the glue mixing before the glue coating structure can continue to work, which makes the overall working efficiency of the device low and inconvenient to use.
