Abstract: A gripping device monitored based on CEMF and a method for controlling the same includes: using a controller to instruct a drive unit to rotate a stepper motor; using the controller to compare the control instruction with a control parameter matrix stored in an access unit; obtaining a CEMF threshold by checking the position of the actual CEMF in the control parameter matrix; using the controller to monitor the actual CEMF; and using the controller to compare the actual CEMF with the threshold, maintaining driving of the stepper motor when the actual CEMF is larger than the threshold, and stopping the stepper motor to maintain the gripping status, when the actual CEMF is smaller than or equal to the threshold. The operation parameters are measured in advance when the stepper motor runs well, which ensures that the objected is stably gripped before abnormality occurs, thus stabilizing the gripping motion.

Abstract: A rotation drive device includes a crankshaft which has two ends dynamically connected to a drive source and a driven device, respectively. The drive source drives the crankshaft to rotate the driven device. The crankshaft structurally changes to make the two ends of the shaft portion connected to the rotation drive portion and the driven portion, respectively, at different central angles, which divides the space into two subspaces which are located two sides of the shaft portion, so that the wire can be arranged in the subspaces at both sides of the shaft portion, thus enhancing the flexibility of wire distribution while improving rotation range of motion.

Abstract: A method for detecting a preload residual rate involves: a. installing a temperature sensor on one of two preloaded elements; b. making the two preloaded elements to move with respect to each other, and recording a time-related temperature variation sensed by the temperature sensor, so as to obtain an initial temperature-rising curve; c. making the two preloaded elements to move with respect to each other, and recording a time-related temperature variation sensed by the temperature sensor, so as to obtain a detected temperature-rising curve; and d. comparing the initial and detected temperature-rising curves, so as to obtain the preload residual rate between the two preloaded elements of the step c to the step b. The method detects a preload residual rate applied to an object when the object is operating while being advantageous in terms of cost, service life, response and accuracy.

Abstract: An internal-circulation-type ball screw includes a nut, a screw shaft, and two returning members. The nut has an internal-thread groove. The screw shaft passes through the nut and has an external-thread groove. The internally and external-thread grooves are aligned to form a helix channel. The screw shaft has a returning channel and two opposite receiving recesses. Each of the receiving recesses is radially communicated between the external-thread groove and the returning channel. The returning members are received in the receiving recesses of the screw shaft and each have a redirecting channel. The redirecting channel is connected between the helix channel and the returning channel, so that balls are allowed to circulate along the helix channel, the redirecting channel and the returning channel. Thereby, the internal-circulation-type ball screw provides good durability, reliability and smoothness in use.

Abstract: A system for the monitoring a preload in a ball screw includes a ball screw, a detecting device, a capturing device and a processing device. The ball screw has a preload. The detecting device detects an operating signal of the ball screw. The operating signal contains information about the ball screw's rotating speed and status. The status refers to a vibration or a sound generated by the operating ball screw. The capturing device is connected to the detecting device and acquires the operating signal. The processing device is connected to the capturing device, and has a threshold. The processing device processes and converts the operating signal into a ball-passing signal. When the ball-passing signal surpasses the threshold, the processing device determines that the ball screw's preload has vanished. Thereby, the system is enabled to determine the current state of the ball screw's preload reliably.
