The invention discloses a novel magnetic separation mechanism. The novel magnetic separation mechanism comprises a coding turntable mechanism, a magnet opening and closing mechanism and washing mechanisms, wherein the magnet opening and closing mechanism is mounted on the coding turntable mechanism; the washing mechanisms are distributed at the periphery of the coding turntable mechanism; the magnet opening and closing mechanism is used for controlling a magnet to adsorb nano magnetic beads in liquid of a reaction cup on the coding turntable mechanism; the washing mechanisms are used for washing the liquid in the reaction cup to separate the nano magnetic beads. By virtue of the novel magnetic separation mechanism, multi-station separation and washing are carried out by the same mechanism; a uniform mixing station is arranged; the action process of one station and the action processes of other stations can be simultaneously carried out; a magnetic particle mixing mechanism does not need to be arranged outside the mechanism; by virtue of the rotation movement of the coding turntable plate, the magnetic particles can be uniformly mixed according to the principle of the cam movement and the principle of eccentric rotation, so that the action processes are achieved; the novel magnetic separation mechanism is simple in structure; and the separation and washing efficiency of the device is improved.

The present invention relates generally to a rotary die bonding apparatus (102) comprising a vertical motion linear actuator and a rotary motion actuator with a plurality of pick up heads (116) for transferring semiconductor die (122) from diced wafer to the lead frame for die bonding process, wherein said plurality of pick up heads (116) performs its assigned task such as pick (126), die bonding (132), inspection (128) and others simultaneously upon reaching its specific location and rotates to another location upon completion of each task to perform the next assigned task.

The invention discloses a high-density standard compact disc stack storage box device, which comprises a plurality of compact disc boxes, an opening and closing device, a detection device, a power device, a supporting structure and a controller, wherein the compact disc boxes are arranged on a compact disc box rotating cage; the compact disc box rotating cage is arranged on a cage shaft; the cage shaft is supported and the supporting structure; the cage shaft and the compact disc box rotating cage are driven by the power device to rotate; the controller and the supporting structure are arranged on a compact disc library manipulator; the opening and closing device and the power device are arranged on the supporting structure; the power device can drive the manipulator to move; the opening and closing device can move along the guide rail of the manipulator with the compact disc library manipulator; and the detection device is installed on a position on which the state of the compact disc box can be detected. The high-density standard compact disc stack storage box device efficiently utilizes space, brings conveniences for the manipulator to open and close the compact disc box and quickly take and store compact discs, can detect the state of the compact disc box in real time and is safe and reliable.

A grafting machine comprises a grafting machine manipulator, a honeycomb stepping mechanism and a stylobate strip feeding device. The grafting machine manipulator is used for moving bee larvae in thehoneycomb stepping mechanism into the stylobate strip feeding device, and the grafting machine manipulator, the honeycomb stepping mechanism and the stylobate strip feeding device are mounted on a frame and can move relative to the frame. The grafting machine manipulator is used for moving the bee larvae in stylobate strips and grabbing and laying off the bee larvae. The honeycomb stepping mechanism is used for moving honeycombs and automatically feeds after the larvae in a whole line of honeycombs are moved, so that the grafting machine manipulator can conveniently move the larvae in a next line of honeycombs. The stylobate strip feeding device is used for pushing out the stylobate strips and moving the stylobate strips back and forth, so that the manipulator can conveniently move the beelarvae into the stylobate strips, and grafting automation is realized.

The invention discloses an instrument conveying device for anesthesiology department clinics, and relates to the field of medical apparatuses and instruments. For solving the problems that an existinginstrument conveying device is simple in structure, not good in functionality and not convenient to use, the instrument conveying device comprises a box with movable wheels at the bottom, an L-shapedpush handle is installed at the front side of the box, symmetrically-arranged fixing rings are fixedly arranged at the inner wall of the bottom of the box, transverse threaded rods are rotationally installed on the two fixing rings respectively, the two threaded rods are opposite in thread screwing direction, and driven bevel gears are fixedly arranged at the opposite ends of the two threaded rods. By arranging forward and reverse rotation motors, a gear ring, a rotating tube, a connecting rod, a driving bevel gear, the driven bevel gears, the threaded rods and an inner threaded tube, two storage boxes can be automatically driven to automatically stretch out from the box as needed, then, tools can be conveniently picked up from the inner sides of the storage boxes for surgery, in the surgery process, the used tools can be placed on a placement disc, and processing is convenient.
