Problems solved by technology

[0008] A disadvantage of these prior art designs is that, for example, a positioning accuracy of about 50 cm is only sufficient for segmenting into rough workspaces, which can help avoid certain serious mistakes (e.g., locking the tool out of a roughly defined environmental confines). ), but this is not sufficient to ensure high quality standards
[0009] Also, a disadvantage of prior art systems is the fact that they are very static for the manufacturing environment
Moreover, their installation requires the installation of dedicated infrastructure
In terms of ever-changing manufacturing environments, product variants, and flexible order-oriented manufacturing, prior art systems must track every change in the product or environment, and each tracked change must be mapped to those by reprogramming, etc. in the system

Embodiment Construction

[0047] figure 1 A sketch according to an embodiment of the present invention is shown to illustrate tool positioning and background. There is a workpiece 3 in the manufacturing environment 2 (for the sake of simplicity, only some main objects in this environment are shown and referenced). The workpiece 3 advances on the assembly line 29, which moves at a constant speed or gradually in the direction shown by the arrow. The worker 28 uses the hand-held tool 1, and the worker 28 moves back and forth to perform the desired task for the workpiece 3. With the tool 3, the worker attaches the screw 7 to the workpiece 3, for example, as shown by the dashed dotted arrow. According to the present invention, the tool 1 is equipped with a camera 4a that takes images for SLAM navigation. The camera 4a images the workpiece 3 and / or the environment 2, as shown by the dotted arrow. According to the posture of the tool 1 to the camera 4a, the image includes only the workpiece 3, only the envi...

Abstract

The invention relates to a tool location system for a handheld tool in a manufacturing environment, wherein the tool is equipped with a camera for capturing images. According to the invention, the location system comprises numerical evaluator means, which is built to determine a tool-location of the tool by a simultaneous location and mapping (SLAM) navigation calculation based on the images from the camera. Therein the tool-location is determined with respect to a global coordinate system in relation to the manufacturing environment from portions of the images which comprise a view of the manufacturing environment and the tool-location is determined with respect to a local coordinate system in relation to the workpiece from portions of the images which comprise a view of the workpiece.

Description

Technical field [0001] The present invention relates to the technical field of manufacturing environment, for example, such as car body manufacturing, aircraft manufacturing, machinery manufacturing and the like. This environment is usually set up as an assembly line or manufacturing unit. [0002] The present invention generally also relates to a tool positioning system in a manufacturing environment according to claim 1 and a method for positioning a hand-held tool in a manufacturing environment according to claim 12. Background technique [0003] US 2011 / 087360 shows an autonomous industrial robot used in a manufacturing environment, which is equipped with a camera and a force sensor. The computing device is embodied to calculate the desired robot motion based on camera and sensor data, so that the robot can automatically assemble parts to predetermined positions of randomly moving workpieces, for example, assembling tires to the car body. [0004] In addition to the automated s...
