First: the long side of the product shape is set as the carrying belt width to avoid acupoint deformation when carrying belt and material;

Second: the convex hull of the carrier belt is designed according to the product needs, and the gap between the convex hull and the product surface is between 0 ~ 0.1 mm. When adjusting the machine, the convex hull of the carrier belt is opposite to the suction nozzle of the machine. During adsorption, the product is placed on the convex hull surface of the carrier belt to prevent product deformation during production;

Third: the carrier belt shall be designed with bumps or stiffeners according to the needs of the product. The height of the bumps shall be between the top surface of the product and the top surface of the carrier belt. A gap of 1.5mm ~ 3.0mm shall be placed between the length / width of the bumps and the product retaining wall;

Fourth: a gap of 0.1mm ~ 0.2mm shall be placed between the bottom of the product and the bottom of the carrier belt to avoid interference between the product and the carrier belt;

Fifth: according to the length / width of the product, put a 0.2 mm gap on one side in the carrier hole;

Sixth: all the planes in the length / width direction in the carrier hole are inclined planes, and the inclined plane and the bottom surface are about 95 °.
