IC carrier plate processing equipment based on positioning structure and positioning process
ActiveCN119629856Aachieve regulationEasy to adjustCircuit board tools positioningInsulating layers/substrates workingPositioning technologyMechanical engineering
The invention relates to the technical field of electrical element assembly manufacturing, and discloses an IC carrier plate processing device based on a positioning structure and a positioning technology.The IC carrier plate processing device comprises a substrate body and a drilling machine body, and a bearing part for positioning the substrate body is arranged on a conveying platform of the drilling machine body; and the bearing part comprises a bearing frame for bearing the substrate main body. The supporting piece is arranged and penetrates through the limiting frame of the movable frame until the fixing block is completely clamped on the inner side of the limiting frame, at the moment, the connecting rod is arranged below the cavity of the bearing frame in a penetrating mode, a worker can change the position of the fixing block on the inner side of the limiting frame by rotating a knob at different rotating angles, and therefore the position of the connecting rod is integrally adjusted; the supporting block is accurately adjusted through the cavity of the bearing frame, and the position of the supporting block on the outer side of the connecting rod is changed through the fixing pin, so that the supporting piece can carry out different supporting and positioning on the base plate main body with various different drilling requirements.
