摘要:
Delivering a receptacle to an instrument comprises supporting a receptacle in a carriage when the carriage is positioned at a first location of the instrument, activating a sensing system coupled to the carriage to confirm that the receptacle is supported by the carriage, moving the carriage, and the receptacle supported therein, to a second location of the instrument, applying a clamping force to the receptacle as the carriage moves from the first location to the second location, at the second location, extracting at least a portion of a fluid contained in the receptacle using a fluid extraction device of the instrument, moving the carriage, and the receptacle supported therein, from the second location to the first location, and releasing the clamping force from the receptacle as the carriage moves from the second location to the first location.

A sample processing station includes two or more container holders on a platform that is rotatable about a central axis of rotation. Each holder is configured to rotate about a secondary axis of rotation. The station includes a capping/decapping mechanism to cap or decap a container held in one of the container holders and a drip tray movable between a first position not under the capping/decapping mechanism and a second position under the capping/decamping mechanism.

A receptacle delivery system for an instrument includes a carriage, a puck supported by the carriage, and a first shelf. The carriage is configured to move from a first location of the instrument to a second location of the instrument. The puck is configured to removably support a receptacle such that a longitudinal axis of the receptacle is substantially coincident with a vertical axis of the puck. The first shelf is positioned at the second location of the instrument and comprises (a) a base extending substantially transverse to the vertical axis of the puck and (b) a first opening defined by the base. When the carriage is positioned at the second location, the longitudinal axis of a receptacle seated in the puck extends through the first opening.
摘要:
A puck for removably supporting a receptacle. The puck includes a plurality of fingers arranged about a vertical axis, where each finger has a contact surface configured to be in contact with a receptacle seated in the puck. One or more springs couple the plurality of fingers, thereby biasing the fingers toward the vertical axis. The puck further includes a supporting disc having (i) a disc sidewall projecting from a base to define a pocket for seating a receptacle, (ii) a plurality of first cavities formed in the base and extending in a direction of the vertical axis, and (iii) a puck passageway extending through opposed portions of the disc sidewall in a direction transverse to and offset from the vertical axis, where each of the fingers is rotatably coupled to the supporting disc at a corresponding first cavity of the plurality of first cavities. A synchronization disc is positioned in the pocket of the supporting disc, where each of the fingers is coupled to the synchronization disc such that the contact surfaces of the fingers move toward and away from the vertical axis in a synchronous manner. The puck additionally includes a retaining ring coupling the plurality of fingers, the supporting disc, and the synchronization disc together.

A container gripping mechanism includes first and second linear rails disposed on opposed sides of a linear rail mount. A first linear rail guide coupled with the first rail is supported on a first gripper finger mount, and a second linear rail guide coupled with the second rail is supported on a second gripper finger mount. A first gripper finger is secured to the first gripper finger mount, and a second gripper finger is secured to the second gripper finger mount. A pinion gear driven by a drive motor engages racks attached to the first and second gripper finger mounts, such that rotation of the pinion in a first direction causes the first and second gripper fingers to move toward each other, and rotation of the pinion in a second direction causes the first and second gripper fingers to move away from each other.
摘要:
A printing module configured to print a label on a curved surface of an article includes an expandable printing mechanism configured to be expanded to an open configuration for receiving the article or contracted to a closed configuration placing the curved surface in an operative position with respect to a print head and an article moving assembly configured to grasp and hold the article and effect relative movement between the curved surface and the print head. The printing mechanism includes contact elements, such as rollers, that contact or otherwise engage the article when the printing mechanism is in the closed configuration and maintain the curved surface in the operative position with respect to the print head during relative movement between the curved surface and the print head.
摘要:
A method of reading machine-readable labels on sample receptacles held by a sample rack. In the method, an absolute position of the sample rack is measured as the sample rack moves between first and second positions in a housing. During movement between the first and second positions, an image is acquired of a machine-readable label associated with each sample receptacle held by the sample rack. The image of each machine-readable label is thereafter decoded.
摘要:
Systems for reading machine-readable labels, for example, two-dimensional barcodes, include a housing, a reader configured to read the machine-readable labels on sample receptacles as a sample rack holding the sample receptacles move between a first position and a second position within the housing. The system includes a processing and control unit configured to decode a read image of the machine-readable labels on each sample receptacle, and configured to associate a decoded read images with the corresponding sample receptacles based on measured positions of the sample rack when the machine-readable label was read.
