Abstract: A split detection device includes: a detection unit, which includes a detection casing and a sensor that is mounted inside the detection casing; a processing unit, which includes a processing casing and a processor that is mounted inside the processing casing; a connection unit, which is electrically connected between the sensor of the detection unit and the processor of the processing unit; and a transmission unit, which is electrically connected between the processor of the processing unit and an external device. By setting up the sensor and the processor inside different casings to be separate from each other, influence of the processor on the sensor can be reduced to thereby improve accuracy of detection.

Abstract: A linear transmission device includes a screw, a moving member, a return element, and a sensor. The moving member is set in the screw to form a load path therebetween. The return element is set in the moving member and has a return path connected to the load path. The return path and the load path constitute a circulating path for balls to run. The moving member has an internal thread with an ineffective thread section. The moving member has a receiving groove adjacent to the ineffective thread section. The sensor is embedded in the receiving groove of the moving member without affecting the operation of the balls. Thus, the linear transmission device of the present invention can solve the problem of the sensor protruding from the moving member, so that the configuration of the surrounding space and the stroke of the moving member will not be affected.

Abstract: An inner circulation ball screw includes a screw shaft, a nut, and a return member. The nut is disposed on the screw shaft to form a load path with the screw shaft. The return member is disposed in an accessory slot of the nut to form a non-load path connected with the load path to form a circulation path for circulation of balls. The return member has a ball-discharging channel provided with one end connected with an ineffective thread section of the nut and the other end communicating with a ball-discharging hole of the nut. Therefore, the balls are allowed to move to the outside of the nut through the ball-discharging channel and the ball-discharging hole for preventing the balls from being stuck in the ineffective thread section, thereby solving the problems of high resistance and damaging to related accessories.

Abstract: A linear actuator and an identification method thereof are characterized in that a memory unit of the embedding device stores the parameter data of the linear actuator, such as the parameters and the axial position of the elongated shaft, and the microprocessor determines whether the sensing device is activated, and through the process of parameter analysis, data transmission, and algorithm calculation, the calculation control device performs an instantaneous calculation to determine the state of the linear actuator, thereby improving the disadvantage of a single function of the conventional technology, avoiding the problem that the unidentified linear actuator causes the abnormality of the sensing device, and effectively finding the problem of abnormal function of the linear actuator.

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.
