Abstract
A machine for manufacturing a mask includes a plurality of carriers mounted to a belt so as and having a plurality of molding cavity inserts. A feed station supplies material from a roll so as to form a sheet of material on to the carriers. A shell forming station is configured to press a molding core inserts into the molding cavity inserts so as to form a shape of the mask. A welding station generates a predetermined ultrasonic vibration at a predetermined frequency and a predetermined amplitude so as to weld the sheet of material. A cutting station cuts out the mask from the sheet of material. A mask grabbing apparatus is configured to grab the mask and position the mask for retrieval.
Claims14
A machine configured to manufacture a mask formed of at least one material supplied by a roll of the at least one material, the machine comprising:
- a controller;
- a frame having a gantry and a support plate disposed beneath the gantry, the support plate fixed to the frame;
- a conveyor operable to rotate belt;
- a plurality of carriers fixedly mounted to the belt so as to be carried around the support plate, wherein the plurality of carriers include a plurality of molding cavity inserts;
- a feed station for supplying the at least from material from the roll to the conveyor, the feed station having a gripper configured to pull the at least one material across one of the plurality of carriers and a guillotine configured to cut the at least one material so as to form a sheet of material on a respective one of the plurality of carriers;
- a shell forming station mounted to the gantry, the shell forming station having a shell support and a plurality of molding core inserts disposed on the shell support, the shell forming station configured to press the plurality of molding core inserts into the plurality of molding cavity inserts pressing the at least one material therebetween so as to form a shape of the mask;
- a welding station, the welding station including a welding base and a plurality of welding horns disposed on the welding base, the plurality of welding horns configured to generate a predetermined ultrasonic vibration at a predetermined frequency and a predetermined amplitude so as to weld the sheet of material;
- a cutting station having a cutting base and a plurality of cutting dies disposed on the cutting base, the plurality of cutting dies configured to cut out a peripheral of the mask from the sheet of material so as to separate the mask from the sheet of material;
- and
- a mask grabbing apparatus rotatable about an axis between a first position and a second position, the mask grabbing apparatus including a plurality of mask gripping cores, wherein in the second position the plurality of mask gripping cores are seated with the plurality of molding cavity inserts;
- a pneumatic intake coupled to each of the plurality of mask gripping cores, the pneumatic intake sucking the mask within each of the plurality of molding cavity inserts so as to retain the mask to the respective one of the plurality of mask gripping cores, the mask grabbing apparatus movable to the first position wherein the mask on each of the mask gripping cores may be retrieved.
