Technical Field

[0001] The utility model relates to a glue coating device, belonging to the field of copper clad plate processing. Background Art

[0002] When producing copper clad laminates, the soft copper foil substrate and the soft insulating layer (PI film) need to be bonded together with glue. The glue is applied to the soft insulating layer through a glue coating device. The glue coating device includes a glue outlet installed on the glue cylinder outlet, and a flat glue outlet is installed on the glue outlet. The glue flows out through the glue outlet to form a flat surface coated on the soft insulating layer. Because the width of the copper clad laminate is different, the width of the soft insulating layer is also different, and the size of the flat glue outlet on the glue outlet is fixed. When the width of the copper clad laminate is not an integer multiple of the width of the flat glue outlet on the glue outlet, two layers of glue will overlap during the glue coating process, which not only increases the amount of glue used, but also the thickness of the overlapping area of ​​the glue is thicker, affecting the quality of the glue coating. Therefore, it is necessary to design a glue coating device suitable for the glue coating needs of copper clad laminates of different widths. Utility Model Content
