Abstract: A filling and covering machine for centrifuge tubes with tethered caps includes a conveying device, a cap-flapping device, a filling device, and a cap-pressing device. The cap-flapping device has an upper planar surface and a cap-guiding member having a starting end portion, an ending end portion that is opposite to the starting end portion, and a guiding surface extending from the starting end portion to the ending end portion, and cooperates with the upper planar surface to define an included angle therebetween decreasing gradually from the starting end portion to the ending end portion to guide a cap of each of the centrifuge tubes with tethered caps toward a tube body thereof.

Abstract: A package opening device of a continuous horizontal packaging machine includes upper and lower package opening units and a squeezing unit. The upper package opening unit includes two upper slide blocks, and two upper suction members respectively fixed to and driven by the upper slide blocks to relatively move in a transverse direction. The squeezing unit includes a guide rail extending in a horizontal direction perpendicular to the transverse direction, and two pushing blocks slidably disposed on the guide rail and movable relative to each other. The lower package opening unit is lower than the upper package opening unit in a height direction perpendicular to the horizontal and transverse directions, and includes two lower slide blocks, and two lower suction members respectively fixed to and driven by the lower slide blocks to relatively move in the transverse direction.

Abstract: An optoelectronic package structure is provided. The optoelectronic package structure includes a carrier and a photonic component. The carrier includes an upper surface and a first lateral surface. The photonic component is disposed over an upper surface of the carrier and includes an optical portion. The carrier includes a recessed portion recessed from the first lateral surface of the carrier, and the optical portion of the photonic component is located within the recessed portion of the carrier from a top view perspective.
