Problems solved by technology

[0003] During workpiece pick-up, workpieces may not be held in an appropriate state due to complex overlapping of workpieces in the stocker and buried parts where workpieces are held.
As a result, the held workpiece cannot be transported to the next process in an appropriate state, and the accuracy of the workpiece handling operation may decrease

Embodiment Construction

[0023] Embodiments are described below with reference to the drawings. In addition, in the following description, the same code|symbol is used for the same element or the element which has the same function, and the overlapping description is abbreviate|omitted.

[0024] Such as figure 1 As shown, the robot system 100 has a robot 101, a stocker 102, a camera (sensor) 103, and a robot controller (control device) 104, and is configured so that the robot 101 can grasp (hold) the stocker 102 one by one. Workpiece W within.

[0025] The robot 101 is a so-called articulated robot, has a base fixed on a fixed surface, and has an arm 101A having a plurality of rotational joints from the base to the tip. Servo motors for driving the joints are incorporated in the arm 101A, and the driving of each joint is controlled by the robot controller 104 .

[0026] The arm portion 101A of the robot 101 has a holding device (holding portion) 10 at its tip. The holding device 10 has a pair of f...

Abstract

A robot system (100) includes a robot (101). The robot (101) includes a holder (10) to hold a first workpiece from among workpieces stored in a stocker (102). A sensor (103) performs shape recognition of the workpieces stored in the stocker (102) and detects a holding state of the first workpiece held by the robot (101). A controller (104) controls the sensor (103) to perform the shape recognition of the workpieces stored in the stocker (102), controls the robot (101) to hold the first workpiece based on the shape recognition and transfer the first workpiece to a particular position in a sensor area of the sensor (103), controls the sensor (103) to detect the holding state of the first workpiece held by the robot (101), and controls the robot (101) to place the first workpiece in a predetermined position or posture based on the detected holding state.

Description

technical field [0001] The invention relates to a robot system and a method for manufacturing a processed object. Background technique [0002] In recent years, various workpiece pick-up technologies have been proposed for taking out and processing workpieces having the same shape, such as bolts, which are randomly stored (so-called bulk) in a stocker from the stocker. In this technology, after performing shape recognition (recognition of three-dimensional position and orientation) of workpieces in the stocker, the workpieces to be held are determined based on the recognition result and taken out from the stocker. [0003] In workpiece pick-up, workpieces may not be held in a proper state due to complex overlapping of workpieces in the stocker, and buried parts where workpieces are held. As a result, the held workpiece cannot be conveyed to the next process in an appropriate state, and there is a possibility that the accuracy of the workpiece handling operation may decrease...
