Abstract: A ball screw includes a load path and a non-load path defined between the screw shaft and the screw nut with the two ends of the non-load path respectively connected to the load path and a reflow channel of the return tube. The ball screw defines an imaginary horizontal plane and an imaginary sloping surface that are intersected with each other at the center axis of the screw shaft. The imaginary horizontal plane passes through the non-load path. The imaginary sloping surface passes through the junction between the non-load path and the load path. The imaginary sloping surface defines a negative included angle within 1˜3 degrees with respect to the imaginary horizontal plane to reduce the impact force rendered by each rolling member to the return tube, enhancing operational smoothness and reducing operational noise.

Abstract: An adjustable lubrication module of a linear guideway includes an end lid disposed at a slider and an oil scraper disposed at the end lid. The end lid has therein two opposing backflow-chambers. A feed-hole disposed between the backflow-chambers and an oil-guiding conduit disposed below the feed-hole are disposed on the end lid. Communication between the feed-hole and the oil-guiding conduit is achieved by a primary oiling-channel. Communications between the oil-guiding conduit and the backflow-chambers are achieved by a secondary oiling-channel. Therefore, oiling-channel adjustment performed on the adjustable lubrication module operating in conjunction with the linear guideway does not entail demounting the end lid from the slider, thereby preventing ball missing. The feed-hole and the oil-guiding conduit are not disposed at the junction of the end lid and the slider; hence, lubrication oil is prevented from flowing over the gap between the end lid and the slider.

Abstract: A method for positioning an endoscope involves installing an auxiliary positioning device on a robot arm, coinciding a terminal of a docking member of the auxiliary positioning device with a spherical remote center of motion defined by the robot arm, inserting and fixing the endoscope inside the auxiliary positioning device, removing the docking member of the auxiliary positioning device so that a terminal of the endoscope coincides with the spherical remote center of motion of the robot arm, and then inserting the endoscope into a body cavity catheter for finalizing positioning. Thereby, the method helps to save time used for preoperative preparation and provides more precise positioning, without using any additional positioning tools to approach the body cavity, thereby reducing the risk of infection.

Abstract: A remote center of motion robotic arm includes an arm unit, a drive unit and a control unit. The arm unit includes a base seat, a first link rotatable relative to the base seat, a mount seat, and a second link pivoted to the first link and rotatable relative to the mount seat. The drive unit includes first and second drive motors for rotating the first and second links. The control unit controls the drive unit to move the first and second links from an initial position to an objective position, such that the relative position between the base seat and the mount seat is maintained after the movement of the first and second links.

Abstract: A sensor assembly includes: a base with an installation space; an electrical connection member disposed on the base; a sensing unit including at least two physical sensors and one integrated circuit board; and a contact member disposed at one end of the base. The sensor assembly is a combination of the temperature sensor and the vibration sensor, the main physical parameters (including back clearance, collision, thermal displacement and lubrication) regarding the operation of the linear motion transmission device can be calculated based on the temperature signal and vibration signals, without requiring the installation of separate different sensors. Therefore, installation space is reduced. The sensor assembly is directly abutted against the linear motion transmission device to detect the change of various physical values in a most direct manner.

Abstract: A circulation member positioning structure for a ball screw includes a nut and a circulation member. The nut has a threaded channel, a socket, and a positioning notch. The socket is provided on a wall of the threaded channel and the positioning notch is provided on a wall of socket. The circulation member has a circulation portion, a circulation track, and a positioning protrusion. The circulation portion is provided in the socket of the nut. The circulation track is distributed over one lateral of the circulation portion and connects with the threaded channel of the nut. The positioning protrusion is provided on an opposite lateral of the circulation portion for being engaged with the positioning notch of the nut. Thereby, the circulation member positioning structure helps to simplify the assembling work of the circulation member and to remain the nut small despite the insertion of the circulation member.
