  • Electronic torque wrench with sensing structure
    Patent number: 10821580
    Abstract: An electronic torque wrench with sensing structure includes a tubular body, a working head and at least one sensing element. The working head includes a head section and a connection section secured in the front end of the tubular body. The head section is positioned at the front end of the tubular body. The sensing element is disposed on an outer circumference of the tubular body. Accordingly, the length of the connection section of the working head is greatly shortened and the internal structure of the tubular body is simplified to lower the material cost and manufacturing cost. In addition, the weight of the torque wrench is reduced and the sensing precision of the sensing element is enhanced, whereby a user can more easily hold the torque wrench and more smoothly use the torque wrench to enhance the whole benefit of the torque wrench.

  • Alignment film coating machine and a coating method
    Patent number: 10821467
    Abstract: An alignment film coating machine and a coating method are provided. The alignment film coating machine includes an equipment for carrying a substrate, a spray head for spraying PI droplets, and an air knife disposed on the equipment and located on one side of the spray head. The air knife is used for moving along the equipment and blowing uniform impact air curtain to the PI droplets after the spray head sprays the PI droplets on the substrate. By adding the air knife into the alignment film coating machine, the diffusion ability of the PI droplets is improved due to the uniform impact air curtain blown by the air knife. The resistance in diffusion is overcome. The PI droplets enter the via hole. Mura, which is induced by a relatively thicker PI film around the via hole as a result of the accumulation of the PI droplets, is prevented.
