Description

Spring core type mobile phone motherboard support, shell fragment welding position tool Technical Field The utility model relates to the technical field of jigs, in particular to a spring core type mobile phone motherboard bracket and a spring sheet welding positioning jig. Background In the mobile phone production and processing process, the mobile phone main board support and the elastic sheet are required to be welded, and before the mobile phone main board support and the elastic sheet are carried out through welding equipment, the mobile phone main board support and the elastic sheet are required to be positioned through corresponding positioning jigs so as to ensure the welding quality. The mobile phone elastic sheet auxiliary fixing jig comprises a jig base and an elastic sheet pressing unit arranged on the jig base, wherein a positioning part for positioning and installing a mobile phone front shell is arranged on the jig base, a positioning column is arranged on the positioning part and used for penetrating through a positioning hole on the mobile phone front shell, each elastic sheet pressing unit comprises a rotating shaft seat, a pressing rod and an elastic sheet pressing head, the rotating shaft seat is arranged on the periphery of the positioning part, one end of the pressing rod is hinged to the rotating shaft seat, the other end of the pressing rod is detachably connected with the elastic sheet pressing head, and the pressing rod is used for driving the elastic sheet pressing head to press and fix the elastic sheet positioned on the mobile phone front shell.
