Description

Technical Field

[0001] The utility model belongs to the technical field of gluing devices, and in particular relates to a gluing device for a copper-clad substrate. 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. Copper clad laminate is the basic material for PCB. When it is used in the production of multi-layer boards, it is also called core board. In the production process of epoxy glass fiber cloth copper clad laminate, the glass fiber cloth is glued by a glue machine and dried to "B stage" (the so-called "B stage" means that a considerable part of the polymer has been cross-linked, but at this moment the material is still partially in a soluble and fusible state). This semi-finished product is commonly known as a prepreg or bonding sheet.

[0003] The commonly used gluing device uses a guide roller to guide the fiberglass cloth into the glue barrel for gluing. The glue liquid is stored in the glue barrel during use. Generally, the guide roller will guide the fiberglass cloth to the upper position of the glue barrel. The glue liquid inside the glue barrel cannot be stirred, and the glue liquid and the inorganic filler in the glue liquid are prone to segregation, resulting in uneven glue coating.

The glue liquid can be coated on the glass fiber cloth. When gluing, the stirring component 4 stirs the glue liquid at the bottom of the glue storage kettle 1, so that the glue liquid is more uniform, the glue liquid is prevented from settling, and the gluing effect is improved. The setting of the circulation component 5 can make the glue liquid inside the glue storage kettle 1 circulate up and down, further improving the uniformity of the glue liquid.

[0021] like Figure 2 and 3 As shown, the stirring component 4 includes a rotating shaft 41, which is rotatably connected to the bottom of the glue storage kettle 1, and the side wall of the rotating shaft 41 is provided with evenly distributed stirring blades 43.
