  • Patent number: 10316402
    Abstract: A crucible, a vacuum evaporation device and a vacuum evaporation system are disclosed. In one embodiment, the crucible includes a crucible body for accommodating an evaporation material therein, a nozzle disposed at a mouth of the crucible body, and a holding groove formed at the outer circumference of the nozzle and configured for accommodating the evaporation material overflowed from the nozzle therein, so that, the overflowed evaporation material (especially aluminum material) is prevented from falling into an interior of a heating source, avoiding damage to a heating element due to a short circuit, and meanwhile, condition of overflow of the evaporation material will be checked easily by observing the holding groove. The crucible according to some embodiments adopts a structural design with a large bottom and small mouth, improving heating area and evaporation rate of the evaporation material.
