Abstract

A system and method for placing an object, which is to be processed on a production apparatus in a precise position, is provided. The system includes at least one location-determining system for determining a relative location of an object in relation to a production apparatus and a positioning apparatus for positioning the object on the production apparatus. The positioning apparatus has a receiving apparatus for receiving and discharging the object, and a movable arm for moving the object from one location to another. The location-determining system has at least one location-detecting device to detect a relative location of the receiving apparatus in relation to the location-detecting device. The location-detecting device is configured to detect a relative location of the object in relation to the location-detecting device and also a relative location of the production apparatus in relation to the location-detecting device.

First claim

What is claimed is:

1. A system for placing an object, which is to be processed on a production apparatus in a precise location, comprising:
at least one location-determining system to determine a relative location of an object, which is to be processed, in relation to a production apparatus; and
a positioning apparatus to position the object on the production apparatus, where the positioning apparatus includes:
a receiving apparatus to receive and discharge the object, and
a movable arm to move the object from a first location to a second location,

wherein the location-determining system has at least one location-detecting device configured to detect a relative location of the receiving apparatus in relation to the location-detecting device,
wherein the location-detecting device is configured to detect a relative location of the object in relation to the location-detecting device, and
wherein the location-detecting device is configured to detect a relative location of the production apparatus in relation to the location-detecting device.

2. The system according to claim 1 ,
wherein the location-determining system has at least one first reference marking and at least one second reference marking,
wherein the first reference marking is arranged at the receiving apparatus and the second reference marking is arranged at the production apparatus, and
wherein the location-determining system is configured to determine a relative location of the first reference marking and the second reference marking in relation to the location-detecting device.

3. The system according to claim 2 , wherein at least one of the first reference marking and the second reference marking has at least one spherical reference body.

4. The system according to claim 2 , wherein the location-determining system is configured to determine a relative location of the object, which is to be processed, in relation to the first reference marking.

5. The system according to claim 4 , wherein the location-detecting device has an optical location-detecting apparatus.

6. The system according to claim 5 , wherein at least one of the first reference marking and the second reference marking has at least one spherical reference body.

7. The system according to claim 1 , wherein the location-detecting device has an optical location-detecting apparatus.

8. The system according to claim 1 , wherein the positioning apparatus is in the form of a robot.

9. The system according to claim 1 , wherein the production apparatus has at least one pocket or at least one raised area for receiving a subregion of the object which is to be processed.

10. The system according to claim 1 , wherein the production apparatus is in the form of a pressing tool.
