The invention discloses a nut hot-melting mounting equipment which solves the technical problems that a nut hot-melting mounting process in the prior art is manually operated, is low in operation speed and is not good in mounting effect. The nut hot-melting mounting equipment comprises a hot-melting mechanism, wherein a plurality of hot-melting heads capable of realizing feeding movement are arranged at the lower end of the hot-melting mechanism; the hot-melting mechanism is mounted on a three-axis mechanical hand; a product positioning mechanism is arranged below the three-axis mechanical hand; a to-be-mounted nut product is placed on the product positioning mechanism; an automatic nut loading mechanism is arranged at one side of the three-axis mechanical hand; a plurality of nuts are arranged at intervals through the automatic nut loading mechanism; the three-axis mechanical hand is used for clamping nuts from the automatic nut loading mechanism and conveying the nuts to positions above the product positioning mechanism; and a hot-melting head in the hot-melting mechanism is used for pressing the nuts into the products to carry out hot-melting and fixing. The nut hot-melting mounting equipment can realize automatic hot-melting mounting of nuts, increases operation speed, and guarantees the mounting effect.
