Definitions

  • the present invention relates generally to a simultaneous analyzer and more specifically, to a vibration mixer for simultaneous analyzer.
  • the solutions or reagents are poured in different wells in a container, and then the container is set in the simultaneous analyzer and vibrated by the simultaneous analyzer through a vibration procedure.
  • the vibration procedure is to reciprocate the container 1 in one direction as shown in FIG. 1 or FIG. 2. This vibration procedure cannot mix every solution or reagent well within a short time.
  • the present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a vibration mixer for simultaneous analyzer, which can be vibrated on a plane in different directions to achieve a mixing operation.
  • the vibration mixer comprises a first motion unit, a second motion unit, and a carrier.
  • the first motion unit comprises a first rail and a second rail arranged in parallel and extending in a first direction, a sliding device coupled to and movable along the first rail and second rail of the first motion unit, and a drive coupled to the sliding device of the first motion unit and adapted to reciprocate the sliding device of first motion unit in the first direction.
  • the second motion unit comprises a first rail and a second rail arranged in parallel and extending in a second direction perpendicular to the first direction and defining with the first and second rail of the first motion unit a motion zone, a sliding device coupled to and movable along the first rail and second rail of the second motion unit, and a drive coupled to the sliding device of the second motion unit and adapted to reciprocate the sliding device of the second motion unit in the second direction perpendicular to the first direction.
  • the carrier is coupled to the sliding device of the first motion unit and the sliding device of the second motion unit and movable by the first motion unit and the second motion unit on a plane within the motion zone.
  • a vibration mixer 100 is shown for use in a simultaneous analyzer, comprising a first motion unit 10, a second motion unit 20, and a carrier 30.
  • the first motion unit 10 comprises a first rail 11, a second rail 12, a sliding device 13, and a drive 14.
  • the first rail 11 and the second rail 12 are arranged in parallel on a platform (not shown), and spaced from each other at a predetermined distance.
  • the sliding device 13 comprises a link 131, two connectors 132, and a driven member 133.
  • the link 131 is coupled to the first rail 11 and the second rail 12 and extending in direction perpendicular to the extending direction of the rails 11, 12, having two distal ends respectively extending over the rails 11, 12.
  • the two connectors 132 are respectively fixedly fastened to the two ends of the link 131 and respectively movable on the first rail 11 and the second rail 12 to hold the link 131 between the rails 11,12, for enabling the link 131 to be reciprocated by an external force along the rails 11, 12 in a first direction, namely, the X-axis direction.
  • the driven member 133 according to this embodiment is a gear.
  • the drive 14 comprises a motor 141 and a transmission rod 142.
  • the transmission rod 142 according to this embodiment is a screw rod disposed at an outer side relative to the first rail 11 in a parallel manner and meshed with the driven member 133.
  • the motor 141 is a servo-motor, having a pinion (not shown) fixedly mounted on the output shaft thereof and meshed with the transmission rod 142.
  • the transmission rod 142 is rotated to move the driven member 133, thereby causing the sliding device 13 to be moved along the rails 11, 12.
  • the sliding device 13 is driven to move leftwards or rightwards in X-axis direction (see FIG. 3).
  • the second motion unit 20 comprises a first rail 21, a second rail 22, a sliding device 23, and a drive 24.
  • the first rail 21 and the second rail 22 are arranged in parallel on the platform in which the first motion unit 10 is installed, and spaced from each other at a predetermined distance. Further, the rails 21, 22 of the second motion unit 20 and the rails 11, 12 of the first motion unit 10 are arranged at right angles, defining a motion zone 40 (see FIG. 3).
  • the sliding device 23 comprises a link 231, two connectors 232, and a driven member 233.
  • the link 131 is coupled to the first rail 21 and the second rail 22 and extending in direction perpendicular to the extending direction of the rails 21, 22, having two distal ends respectively extending over the rails 21, 22.
  • the two connectors 232 are respectively fixedly fastened to the two ends of the link 231 and respectively movable on the first rail 21 and the second rail 22 to hold the link 231 between the rails 21, 22, for enabling the link 231 to be reciprocated by an external force along the rails 21, 22 in a second direction, namely, the Y-axis direction.
  • the driven member 233 according to this embodiment is a gear.
  • the drive 24 comprises a motor 241 and a transmission rod 242.
  • the transmission rod 242 according to this embodiment is a screw rod disposed at an outer side relative to the first rail 21 in a parallel manner and meshed with the driven member 233.
  • the motor 241 is a servo-motor, having a pinion (not shown) fixedly mounted on the output shaft thereof and meshed with the transmission rod 242. Upon operation of the motor 241, the transmission rod 242 is rotated to move the driven member 233, thereby causing the sliding device 23 to be moved along the rails 21, 22. By means of controlling forward/backward rotation of the motor 241, the sliding device 23 is driven to move forwards or backwards in Y-axis direction (see FIG. 3).
  • the carrier 30 is adapted to carry a multi-well container for holding different solutions or reagents for mixing, comprising a flat rectangular carrier base 31 and four sleeves 32 respectively provided at the four sides of the flat rectangular carrier base 31.
  • the four sleeves 32 are arranged in two pairs respectively sleeved onto the links 131, 231 such that the links 131, 231 can move the carrier 30 within the aforesaid motion zone 40.
  • the container that holds prepared solutions or reagents is fastened to the carrier 30.
  • NE-SW North East-South West
  • the carrier 30 is moved by the links 131, 231 to a predetermined NE (North East) location (see FIG. 5).
  • the carrier 30 After the carrier 30 has been moved to the predetermined NE (North East) location, the drive 14 of the first motion unit 10 and the drive 24 of the second motion unit 20 are reversed, thereby causing the drive 14 of the first motion unit 10 to carry the respective sliding device 13 toward the left side (West) and the drive 24 of the second motion unit 20 to carry the respective sliding device 23 toward the front side (South), and therefore the carrier 30 is moved by the links 131, 231 to a predetermined SW (South West) location (see FIG. 6).
  • the carrier 30 By means of repeating the aforesaid action, the carrier 30 is reciprocated in NE-SW (North East-South West) direction as shown in FIG. 4, and the container in moved to and fro with the carrier 30, causing the contained solutions or reagents to be respectively well mixed.
  • the objective of the invention is to let the carrier 30 be moved in the motion zone 40 within any of the four quadrants (on the same plane).
  • the carrier 30 can be reciprocated in another way.
  • the drive 14 of the first motion unit 10 and the drive 24 of the second motion unit 20 are reversed, thereby causing the drive 14 of the first motion unit 10 to carry the respective sliding device 13 toward the right side (East) and the drive 24 of the second motion unit 20 to carry the respective sliding device 23 toward the front side (South), and therefore the carrier 30 is moved by the links 131, 231 to a predetermined SE (South East) location (see FIG. 9).
  • NW-SE North West-South East
  • the container in moved to and fro with the carrier 30, causing the contained solutions or reagents to be respectively well mixed.
  • the carrier 30 is reciprocated linearly.
  • the first and second drives 14, 24 can be intermittently shifted between forward rotation and backward rotation, causing the carrier 30 to be alternatively turned clockwise and counter-clockwise as shown in FIG. 10.
