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 nut clamping and picking device. The nut clamping and picking device comprises a fixed seat. A sliding groove is formed in the side wall of the front side of the fixed seat.A limiting rod is fixedly connected between the inner top wall and the inner bottom wall of the sliding groove jointly. A sliding block matched with the limiting rod is slidably arranged on the outerside wall of the limiting rod in a sleeving mode. The front side of the sliding block extends out of the sliding groove and is fixedly connected with a connecting block. Rotating rods are rotatably connected to the side walls of two sides of the connecting block. Arc-shaped clamping rods are rotatably connected to the lower side walls of both sides of the fixed seat. The ends, away from the fixedseat, of the rotating rods are rotatably connected to the arc-shaped clamping rods. Clamping blocks are fixedly connected to the ends, away from the fixed seat, of the arc-shaped clamping rods. According to the nut clamping and picking device, a telescopic mechanism, a pulling plate, a pull ring, a connecting rod, the sliding block, the connecting block, the rotating rods, the arc-shaped clampingrods, the clamping blocks and a rubber block are arranged, so that nuts are picked up more conveniently, and the inconvenience of manual picking is avoided.
