Definitions
- the invention relates to a method for supporting a work step in the manufacture of a product, with the components required for carrying out the work step being provided, the tools required for carrying out the work step being provided and a work surface on which the work step is to be carried out being provided.
- the invention also relates to a system for supporting a work step in the manufacture of a product, which comprises components required for carrying out the work step, tools required for carrying out the work step and a work surface on which the work step is to be carried out.
- DE 102017002 963 A1 discloses a manufacturing plant and a method for operating a manufacturing plant to manufacture a product.
- the production facility includes a vehicle on which a robotic arm is arranged.
- the vehicle with the robot arm acts as an assistant when assembling a product.
- a method for operating a production facility and a production facility are also known from DE 102017002 964 A1.
- the production plant has a higher-level controller.
- the invention is based on the object of specifying a method and a system for supporting a work step in the manufacture of a product.
- the object is achieved by a method for supporting a work step in the manufacture of a product having the features specified in claim 1.
- Advantageous refinements and developments are the subject of the dependent claims.
- the object is also achieved by a system for supporting a work step in the manufacture of a product with the features specified in claim 8.
- Advantageous refinements and developments are the subject of the dependent claims.
- a method according to the invention for supporting a work step in the manufacture of a product components required for carrying out the work step are provided, tools required for carrying out the work step are provided and a work surface is provided on which the work step is to be carried out.
- An animated image sequence of the work step to be carried out is projected onto the work surface by a video projector.
- the animated image sequence has images of the components required to carry out the work step and images of the tools required to carry out the work step.
- the work step to be carried out includes screwing a screw into a drilled hole using a cordless screwdriver.
- the screw represents a component required to carry out the work step
- the cordless screwdriver represents a tool required to carry out the work step.
- the work step is to be carried out on a work surface provided for this purpose. Images of the screw, images of the cordless screwdriver and an animated sequence of images of the screw being screwed into the drill hole using the cordless screwdriver are thus projected onto the work surface.
- the work step takes place at a workstation set up for this purpose. A worker at the workstation who carries out the work step in the manufacture of the product can thus see which components are to be processed with which tool and how.
- the worker is thus supported in carrying out the work step. Errors during the execution of the work step can thus be avoided.
- the components required to carry out the work step are removed from the work surface.
- the work step to be carried out is, for example, part of a pre-assembly and takes place on a table or on a workbench.
- the work surface on which the work step is to be carried out is a surface of the table or workbench which remains at the work station after the work step has been completed. If necessary, the processed components are brought to another work station for further processing.
- At least one component required to carry out the work step is firmly connected to the work surface during the work step, and after the end of the work step the at least one component required to carry out the work step remains on the work surface.
- the work step to be carried out is, for example, final assembly.
- the work surface on which the work step is to be carried out is a surface of a base plate.
- the work step includes fastening the component, for example a screw, to the base plate. After completion of the work step, the base plate is removed from the workstation together with the components attached to it.
- the images of the components required to carry out the work step and/or the images of the tools required to carry out the work step are projected by the video projector onto a location on the work surface where the work step is to be carried out. For example, a screw to be driven into a drilled hole is projected to a location on or immediately adjacent to the drilled hole. This provides the worker with even more support when carrying out the work step.
- the animated image sequence of the work step to be carried out includes a movement of at least one required component during the work step and/or a movement of at least one required tool during the work step.
- the animated image sequence of the work step to be carried out includes, for example, the movement of a screw into a drilled hole, with the screw being turned by a cordless screwdriver.
- an image sequence of the execution of the work step is recorded by a camera and stored. If an error is detected in the manufactured product, it is possible to analyze the work step at which the error occurred by evaluating the stored image sequence.
- the stored image sequence is evaluated by an evaluation unit.
- the evaluation unit checks in particular whether the work step has been completed and/or whether the work step has been carried out correctly. If the work step has been carried out and completed correctly, a corresponding message is generated and the next work step is carried out. If the evaluation unit detects an error during the execution of the work step, a corresponding message is also generated and the worker is requested to correct it.
- a system for supporting a work step in the manufacture of a product comprises components required for carrying out the work step, tools required for carrying out the work step and a work surface on which the work step is to be carried out.
- the system also includes a video projector, which projects an animated image sequence of the work step to be carried out onto the work surface.
- the animated image sequence has images of the components required to carry out the work step and images of the tools required to carry out the work step.
- the work step to be carried out involves screwing a screw into a drilled hole using a cordless screwdriver.
- the screw represents a component required to carry out the work step
- the cordless screwdriver represents a tool required to carry out the work step.
- the work step is to be carried out on a work surface provided for this purpose.
- the video projector projects images of the screw, images of the cordless screwdriver and an animated sequence of images of the screw being screwed into the drill hole using the cordless screwdriver onto the work surface.
- the work step takes place at a workstation set up for this purpose. A worker at the workstation who carries out the work step in the manufacture of the product can thus see which components are to be processed with which tool and how.
- the system also includes a camera which records and stores an image sequence from the execution of the work step. If an error is detected in the manufactured product, it is possible to analyze the work step at which the error occurred by evaluating the stored image sequence
- the system also includes an evaluation unit which evaluates the stored image sequence, the evaluation unit checking in particular whether the work step has been completed and/or whether the work step has been carried out correctly. If the work step has been carried out and completed correctly, the evaluation unit generates a corresponding message and the next work step is carried out. If the evaluation unit detects an error when carrying out the work step, a corresponding message is also generated and the worker is asked to correct it.
