  • Patent number: 11834277
    Abstract: A multi-station cam carrying mechanism, including a baseplate, a rotary shaft in the middle of the baseplate, an electric motor connected to the bottom of the rotary shaft, a rotary plate at an upper part of the rotary shaft, mounting frames on the baseplate, a mounting plate on the mounting frames, an annular sliding groove on a bottom face of the mounting plate along a cam trajectory, and multiple grabbing and transferring assemblies annularly and uniformly arranged at intervals, with bottom parts slidably arranged on the rotary plate and top parts slidably arranged in the sliding groove. The electric motor drives multiple stations to carry products simultaneously, and undergoes a reciprocating movement along the cam trajectory, grabhooks on the assemblies reciprocate vertically to grab and transfer the products, so that the products are sequentially transferred from one station to the next station.

  • Patent number: 9297744
    Abstract: Device and method for measuring phase retardation distribution and fast axis azimuth angle distribution of birefringence sample in real time. The device consists of a collimating light source, a circular polarizer, a diffractive beam-splitting component, a quarter-wave plate, an analyzer array, a charge coupled device (CCD) image sensor and a computer with an image acquisition card. The method can measure the phase retardation distribution and the fast axis azimuth angle distribution of the birefringence sample in real time and has large measurement range. The measurement result is immune to the light-intensity fluctuation of the light source.
