Abstract: A linear transmission device with capability of wireless power supply includes a transmission mechanism and a wireless power supply module. The transmission mechanism includes a long shaft part and a moving part. The long shaft part defines an axis. The moving part is disposed on the long shaft part in a manner that the moving part is movable along the axis. The wireless power supply module includes a magnet-providing part disposed on the long shaft part for providing a magnetic field and an induction coil disposed on the moving part. A direction of the magnetic field is parallel to the axis. A normal vector of the induction coil is parallel to the direction of the magnetic field. When the moving part is moved along the axis, a current is induced in the induction coil through variation of the magnetic field.

Abstract: A linear transmission device includes: an elongated shaft member, a moving module, a rolling unit, a return assembly, a sensor and a data receiving unit. The linear transmission device has a simple structure. The sensor is disposed at the junction of the first return pipe and the second return pipe of the return assembly to timely detect the change in the distance between the rolling elements, which can determine whether there is an abnormality in the shape of the spacers. With the sensor outputting detecting signals, it can stop the terminal immediately to confirm the condition of the workpieces and the machine, avoiding the structural damage of the machine and the workpiece caused by the continuous operation. The sensor can also serve as a medium for transferring data, further facilitating maintenance.

Abstract: A dustproofing device for use with a linear module includes a dustproofing band disposed around a first pulley pivotally connected to a first end unit and a second pulley pivotally connected to a second end unit. Two ends of the dustproofing band fixedly connect to a fixing platform. The fixing platform fixedly connects to a moving platform of the linear module. A top lid is fixedly disposed on the first end unit and the second end unit and covers the fixing platform, so as for the dustproofing device to be mounted on the linear module. Since the linear module is covered with the first end unit, a first lateral lid, the second end unit and the top lid, not only is the linear module rendered dustproof, but it also takes less time than before to mount the dustproofing device in place.

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.

Abstract: A hydrostatic linear guideway includes a rail, a slider coupled to the rail, and two load blocks disposed between the rail and the slider. A load portion of each load block is spaced from the groove wall of an outer groove of the rail and has an oil chamber facing toward the groove wall of one respective outer groove of the rail, such that an oil film is formed between the rail and each load block. A bearing portion of each load block is abutted against the groove wall of an inner groove of the slider so that the two load blocks are moved synchronously with the slider. Thus, the hydrostatic linear guideway of the present invention has the oil chamber defined in each load block and does not require additional processing of the slider, achieving the purpose of reducing the difficulty of the manufacturing process.
