Latest Patents

One of his latest patents is a method for mold protection of crank-type clamping units. This invention provides a method and apparatus that utilizes the high response characteristics of motors along with a new control method. The system employs a continuously variable restrictive motor output scheme, which works in conjunction with the mechanical characteristics of the toggle mechanism. This ensures a substantially constant mold protective force at all positions. The mold protective force can be adaptively adjusted based on different types of molds and motion conditions, effectively protecting the mold during abnormal conditions. This innovation eliminates the drawbacks of prior art, ensuring safety for the mold, machine, and operators.

Another notable patent is a computer-aided embroidery machine for pattern and data preparation. This method allows for the preparation and testing of predetermined patterns. It includes steps such as comparing the size of the pattern with an embroidery table device to ensure that the intended operation does not exceed defined boundaries. The method also determines an appropriate embroidery frame and provides a completed simulation and trial embroidering process without lowering the needlebar, thus validating the pattern layout.
