Abstract: A cross laser calibration device used to calibrate a tool center point is provided. The calibration device includes a coordinate orifice plate, a set of cross laser sensors and a rotational and translational movement mechanism. The coordinate orifice plate has an orifice center point. The set of cross laser sensors is arranged on the coordinate orifice plate to generate cross laser lines intersecting at the orifice center point. The set of cross laser sensors is driven by the second motor to rotate around the center point of the second motor, wherein the orifice center point has an off-axis setting relative to the center point of the second motor.

Abstract: This disclosure relates to a belt grinder includes frame and first grinding assembly. The first grinding assembly includes transmission roller set, grinding belt and adjusting assembly. The transmission roller set includes driving roller and driven roller. Both the driving roller and the driven roller are rotatably disposed on the frame. The grinding belt is installed over the driving roller and the driven roller. The adjusting assembly includes rotatable component and contact rollers. The rotatable component is rotatably disposed on the frame. Rotation axis of the rotatable component is parallel to rotation axis of the driving roller. The contact rollers are rotatably disposed on the rotatable component. Contact rollers are different in shape. The rotatable component is rotatable with respect to the frame so as to force one of the contact rollers to contact or to be separated from the grinding belt.

Abstract: A method further includes the following steps. Firstly, a three-dimensional picture under a generated background condition is generated, wherein the three-dimensional picture includes a three-dimensional object image. Then, a two-dimensional picture of the three-dimensional picture is captured, wherein the two-dimensional picture includes a two-dimensional object image of the three-dimensional object image. Then, an object region of the two-dimensional object image is recognized. Then, an exposed ratio of an exposed area of an exposed region of the object region to an object area of the object region is obtained. Then, whether the exposed ratio is greater than a preset ratio is determined. Then the exposed region is defined as the pick-and-place region when the exposed ratio is greater than the preset ratio.

Abstract: A detecting method for a workpiece surface includes the following steps. Firstly, a workpiece is provided with a first environment, wherein the first environment has a first environmental temperature higher than a first saturation temperature corresponding to an environmental-relative humidity. Then, the workpiece is provided with a second environment, wherein the second environment has a second environmental temperature lower than the first environmental temperature, such that a itself-temperature of the workpiece reduces to a mist temperature, wherein the mist temperature is substantially equal to or higher than the second environmental temperature. Then, the workpiece is provided with a mist environment, wherein the mist environment has a mist-saturation temperature corresponding to a mist-environmental relative humidity is equal to or higher than the mist temperature for misting a surface of the workpiece. Then, the surface of the misted workpiece is detected.
