An automated calibration system for a workpiece coordinate frame of a robot includes a physical image sensor having a first image central axis, and a controller for controlling the physical image sensor adapted on a robot to rotate by an angle to set up a virtual image sensor having a second image central axis. The first and the second image central axes are intersected at an intersection point. The controller controls the robot to repeatedly move back and forth a characteristic point on the workpiece between these two axes until the characteristic point overlaps the intersection point. The controller records a calibration point including coordinates of joints of the robot, then the controller moves another characteristic point and repeats the foregoing movement to generate several other calibration points. According to the calibration points, the controller calculates relative coordinates of a virtual tool center point and the workpiece to the robot.

A system for establishing a junction trace of an assembly includes a surface model creating module, a processing module, and a material inspection module. The assembly includes a first part and a second part assembled with each other. The surface model creating module scans the first part and the second part to separately establish first surface model data and second surface model data. The processing module establishes assembled surface model data according to the first surface model data and the second surface model data, determines a junction region from the assembled surface model data, and determines inspection points mapped on the assembly according to the junction region. The material inspection module inspects materials of the assembly at the inspection points. The processing module establishes a junction trace of the first part and the second part in the assembly according to a material inspection result.

A system for calibrating tool center point of robot is provided, which may include a first image sensor, a second image sensor, and a controller. The first image sensor may have a first image central axis. The second image sensor may have a second image central axis not parallel to the first image central axis, and intersect the first image central axis at an intersection point. The controller may control a robot to repeatedly move a tool center point thereof between the first and the second image central axis. The controller may record a calibration point including the coordinates of the joints of the robot when the tool center point overlaps the intersection point, and then move the tool center point and repeat the above steps to generate several calibration points, whereby the controller may calculate the coordinate of the tool center point according to the calibration points.

A harmonic drive includes a circular rigid internal gear, a circular flexible external gear, a wave generator, a cover, and a fan blade. The circular flexible external gear is disposed in the circular rigid internal gear, and the wave generator has at least one through hole and is disposed in the circular flexible external gear. The cover and the fan blade are respectively disposed at two opposite sides of the wave generator, and the cover is located in the circular flexible external gear. The cover and the wave generator form an air chamber together, and the through hole and an air flow opening are respectively in communication with the air chamber. The wave generator operates to drive the fan blade to operate. The fan blade rotates to generate an air flow, thus performing heat dissipation on the harmonic drive.

A dissection apparatus is disclosed. The dissection apparatus includes a supporting mechanism, a holder, a driving element rotating the holder, a cam fixed to the supporting mechanism, a first sliding element, a second sliding element, a dissecting device disposed on the first sliding element, an aspirating device disposed on the second sliding element. When the holder rotates to move the dissecting device from a first idle position to an operating position, the first sliding element is lowered by the guide of the cam enabling the aspirating device to move from the operating position to a second idle position. When the holder rotates to move the aspirating device from the second idle position to the operating position, the guide of the cam lowers the second sliding element, thus, allowing the dissecting device is able to move from the operating position to the first idle position.

An apparatus for detecting manufacturing parameters of a machine tool is provided, which comprises at least a sensing and transmitting module, and a receiving module. The sensing and transmitting module has a sensor and a wireless transmitting module. The sensor generates a sensing signal with respect to processing parameter of the machine tool. The wireless transmitting module converts the sensing signal into a wireless signal and transmits the wireless signal to the receiving module. Then the wireless signal is decoded and sent to a processing unit for compensating the machine tool. In the present invention, it is not necessary to consider wiring arrangement so that the sensors can be disposed at positions that are close to the mechanism whose operating status could affect the machining process and the compensation, generated according to the foregoing sensing data, for machine tool will be more effective to improve the machining accuracy.
