Problems solved by technology

Therefore, in the three-dimensional measuring device, the number of cables for connecting the camera and the control unit tends to be large compared with that in the two-dimensional measuring device, and there is a problem that depending on the shape of the measuring device and the arrangement of the cables , the driving range of the robot is limited by
Therefore, the robot cannot be driven in the target path

Embodiment Construction

[0014] A first exemplary embodiment of the present invention will be described below. figure 1 is a schematic diagram illustrating a system capable of holding an object using a robot including a three-dimensional measuring device according to the first exemplary embodiment. The three-dimensional measurement device 100 may also be called a 3D vision or 3D visualization device. The three-dimensional measuring device 100 is connected to a flange (mounting portion) disposed at the end of the last joint portion 107 of the robot 10 . In addition, a manipulator 50 serving as an end effector is attached to the three-dimensional measuring device 100 . In this way, the three-dimensional measuring device 100 is deployed between the robot 10 and the manipulator 50 .

[0015] The robot control unit 20 controls the robot 10 and transmits a trigger signal to the three-dimensional measuring apparatus 100 based on the position of the robot 10 to start measurement. Based on the trigger signa...

Abstract

Three-dimensional measurement devices, systems, and methods of production are disclosed. The three-dimensional measurement device includes an attachment portion for attaching the three-dimensional measurement device to a robot, a flange for attaching an end effector, a sensor configured to receive light from an object, and a calculation unit configured to determine three-dimensional information about the object by performing a calculation using data obtained by the sensor. When viewed from the flange, the shortest distance among the distances from the center of the flange to the outer peripheral edge of the calculation unit is less than or equal to the radius of the attachment portion or the flange.

Description

technical field [0001] The invention relates to a three-dimensional measuring device, system and production method. Background technique [0002] In recent years, robots have been used to perform complex tasks previously performed by humans, such as picking components of industrial products. A manipulator capable of holding an object and making other movements is controlled based on measurements of the object performed by a measuring device mounted on the robot. In general, a measurement device is attached to the tip of the robot's drive shaft so that a wide range of viewing angle information can be acquired. For example, US Patent Application Publication No. 2018 / 0361589 discusses a measurement device that can be attached to the end of a robotic arm. In the measuring device discussed in US Patent Application Publication No. 2018 / 0361589, an image of an object to be measured is captured by a single camera mounted on the measuring device based on an instruction signal from ...
