Description

Technical Field

[0001] The utility model relates to the technical field of positioning platforms, in particular to a positioning platform compatible with back filling and bottom cylinder filling. Background Art

[0002] Polyurethane foam (PU foam) is a polymer product made by a chemical reaction between isocyanate and polyol in the presence of additives, which generates gas and expands to form a fixed shape. It is widely used in furniture, automobiles, insulation, packaging and other fields. Its production process requires strict control of raw material ratios, reaction conditions and molding technology.

[0003] Most factories on the market use manual labor to add foaming liquid into the foaming mold. The common forms of the filling port of the foaming mold are "back filling" and "bottom tank filling". The foaming mold is transported by a roller conveyor belt. This method relies on manual labor and depends on the individual's technical level in terms of production efficiency and foaming quality. In order to adapt to the development trend, our factory has introduced an automated production line for foaming mold transportation and filling with foaming liquid to improve the factory's production efficiency and optimize the quality of production products. The existing automated production line for filling foaming liquid uses a conveyor belt to transport foaming liquid. The mold is brought to a fixed location and picked up by a robotic arm and transferred to a filling station for filling with foaming liquid; centering adjustment components are arranged on both sides of the conveyor belt to adjust its position so that the foaming mold is centered and aligned, making it easier for the robotic arm (negative pressure suction cup robotic arm) to pick up the mold. However, when the foaming mold models are different, the center of gravity of the foaming mold is located at a different position, and the centering method cannot make the center of gravity of the foaming mold located at the optimal picking point of the robotic arm, resulting in poor stability when the robotic arm transfers the foaming mold. For this purpose, a positioning table compatible with back injection and bottom tank injection is provided. Utility Model Content
