Description

Technical Field

[0001] The utility model relates to the technical field of PP sheet stacking, in particular to a PP sheet stacking device. Background Art

[0002] PP sheets are key materials in the production of multi-layer printed circuit boards, primarily composed of resin and reinforcement materials. Common types of reinforcement materials include fiberglass cloth, paper-based materials, and composite materials. PP sheets used in multi-layer printed circuit boards mostly use fiberglass cloth as reinforcement. Stacking devices refer to various devices used to overlap, stack, or assemble multiple parts, components, or materials in a certain order and manner during industrial production, equipment manufacturing, or assembly.

[0003] However, the existing stacking device generally transports the PP sheets through a conveyor belt. The current stacking device generally places the PP sheets directly on the conveyor belt for transportation, or uses a fixed template to fix the PP sheets on it. The former will cause the PP sheets to tilt, making it inconvenient to take them, and the latter can only transport PP sheets of a single specification, which is relatively inconvenient. For this reason, we propose a PP sheet stacking device. Utility Model Content
