Honda Motor has been granted a patent for a system that aids in repairing stamping press dies. The system includes an imaging system that scans the pressing surface of the die to determine its profile. A computing device then compares the determined profile to a desired profile and generates a repair template based on dimensional variations. Finally, a projection system displays the repair template on the pressing surface. GlobalData’s report on Honda Motor gives a 360-degree view of the company including its patenting strategy.

A system for repairing a stamping press die
A recently granted patent (Publication Number: US11685005B2) describes a system and method for repairing a stamping press die. The system includes an imaging system that performs scans on the pressing surface of the die to determine its profile. A computing device then compares the determined profile to a desired profile and generates a repair template based on the dimensional variations between the two profiles. This repair template is displayed on the pressing surface using a projection system.
The patent also mentions that the imaging system can perform additional scans on the pressing surface as work is performed, allowing the computing device to update the repair template accordingly. Additionally, the imaging system can scan the pressing surface to determine the original profile, which can be defined as the desired profile by the computing device.
The computing device is further configured to selectively define the repair template from a plurality of visual cues. These visual cues represent dimensional variations in the determined profile from the desired profile. The cues can include positive or negative dimensional variations and can be defined based on predefined tolerances.
The system described in the patent includes a time-of-flight camera sensor as the imaging system. This type of sensor measures the time it takes for light to travel to the surface and back, allowing for accurate scanning of the pressing surface.
In summary, the granted patent describes a system and method for repairing stamping press dies using an imaging system, computing device, and projection system. The system allows for the comparison of the determined profile of the pressing surface to a desired profile, generating a repair template based on dimensional variations, and displaying the template on the surface. The system can also update the repair template in real-time and selectively define the template based on visual cues. The use of a time-of-flight camera sensor ensures accurate scanning of the pressing surface.
