Work efficiency and the accuracy of repetitive positioning movement are important indicators for measuring an automated production line. Currently, some workstations are completed by manual operation, which not only increases labor costs but also cannot guarantee speed and accuracy. In a dust-free workshop, too many personnel will also cause pollution, dust, static electricity, etc. In such a situation, it is necessary to use certain automated equipment to complete the work, design specific structures and fixture toolings to replace repetitive flow operations, and currently, most mechanical structures are gear racks, cylinder modules, and motor screw sliders for execution.
