  • Publication number: 20240003825
    Abstract: A mapping device is adapted for detecting a plurality of test objects disposed in a container, and arranged along a detecting direction. The mapping device includes: a first sensor group defining a first optical axis, and adapted to be disposed at a front side of the container to move in the detecting direction for detecting the test objects; and a second sensor group defining a second optical axis, and adapted to be disposed at the front side of the container to move in the detecting direction for detecting the test objects. The second optical axis is inclined relative to the first optical axis, and is disposed ahead of the same in a front-rear direction of the container and at a downstream side of the same in the detecting direction.

  • Patent number: 10836052
    Abstract: A connection module includes a shaft member that can be rotated in place and can be lifted up and down, two wires arranged side by side and spirally wound on the shaft member, and an holder block connected with the bottom end of the shaft member and the bottom end of each wire such that the holder block drives the two wires to expand or to contract along the axial direction of the shaft member or to spiral in the axial direction of the shaft member when the holder block is driven by the shaft member. Thus, the connection module of the present invention can simplify the conventional complicated wiring mode, thereby saving operation space and reducing the risk of line breakage.

  • Patent number: 10744652
    Abstract: An adaptive control method includes steps of: storing N number of different speed setting values; assigning an i-th one of the speed setting values to serve as a target speed value; sampling, when the gripping module is performing a first action in a steady state period, a feedback voltage signal resulting from the gripping module to obtain Stall Guard Values (SGVs); averaging the SGVs to obtain an average SGV; and calculating, based on the average SGV and a predetermined SGV deviation, a Stall Guard Threshold (SGT) for subsequent control of the electric gripper.

  • Patent number: 8960038
    Abstract: A motion transmission module with a cooling device is aimed at solving the disadvantage of the conventional motion transmission module that the cooling structure of the conventional motion transmission module would increase the length or outer diameter of the nut. The nut is formed with a flat surface for mounting the cooling device, so that the length of the nut won't be increased. Furthermore, the cooling device also serves as a positioning block to fix the return member, it doesn't increase the outer diameter of the nut.
