Abstract
When cleaning a mold using a mold cleaning system, three-dimensional image data of a molding surface of the mold is acquired by a camera, movement of arms is controlled by a control device based on the acquired image data, and a laser head is moved along the molding surface while a laser beam provided from a laser oscillator is irradiated to remove contamination adhered to the molding surface. Cleaning is performed on a specific site, using a relatively small laser head, or also using a relatively large laser head, or cleaning is performed using a laser head having a variable laser irradiation width and setting an appropriate laser irradiation width for each site to be cleaned.
Claims10
A mold cleaning system, comprising:
- a laser oscillator;
- a laser head configured to irradiate a laser beam provided from the laser oscillator onto a molding surface of a mold;
- an arm configured to freely move the laser head three-dimensionally;
- and
- a control device configured to control movement of the arm;
- wherein
- a camera configured to acquire three-dimensional image data of a molding surface of a mold to be cleaned is provided,
- a plurality of laser heads with different head sizes are provided as the laser head, the laser heads being configured to irradiate laser beams and clean the molding surface while the laser heads are moved along the molding surface as controlled by the movement of the arm by the control device based on the image data acquired by the camera when cleaning the mold, and
- the control device is configured to:
- cause cleaning to be performed with regard to a specific preset site, using a relatively small laser head, or using a relatively small laser head in addition to a relatively large laser head,
- determine a cleanliness state of the molding surface based on the three-dimensional image data of the molding surface of the mold after cleaning, acquired by the camera,
- store the determined cleanliness state and position information of the molding surface, and
- cause the laser beam to be again irradiated from the laser head and cause cleaning to be performed with regard to a position of the molding surface where the determined cleanliness state does not satisfy preset standards.
