Transport device for individualized sheet-shaped workpiece with suction holes
The granted patent (Publication Number: US11926502B2) discloses a transport device designed to efficiently transport individualized sheet-shaped workpieces. The device includes an annular transport belt with suction holes, first and second decompression chambers along the belt's path, and a vacuum degree adjusting mechanism in the first chamber. The chambers have resin bottoms with vent holes aligned with the suction holes on the belt, allowing the workpiece to be transported in a suspended state. The vacuum degree is controlled within a predetermined range based on the workpiece's mass and the frictional resistance between the belt and the resin member.
Furthermore, the patent describes how the decompression chambers suction the workpiece through the suction holes and vent hole towards the belt's first surface, ensuring secure attachment during transportation. Additionally, the first decompression chamber includes a blow pipe for introducing high-pressure gas, enhancing the device's functionality. This innovative transport device offers a practical solution for handling sheet-shaped workpieces with precision and efficiency, showcasing advancements in material handling technology within manufacturing processes.
