The invention discloses a positioning device for
welding semiconductor parts. The positioning device comprises a feeding table, extension plates, a translation mechanism, a feeding and discharging mechanism, a limit mechanism and an adsorption mechanism, the outer side of the feeding table is provided with a through groove, the both sides of the feeding table are correspondingly and fixedly connected with the extension plates, the middle part of the feeding table is provided with the limit mechanism, the translation mechanism comprises track racks, guard plates, a connecting plate, a first
servo motor, a driving rod, a driving gear and a shift fork, the track racks are fixedly connected on the upper sides of the extension plates, the upper sides of the track racks are correspondingly provided with the guard plates, the connecting plate and the driving rod are arranged between the two guard plates, and the connecting plate and the guard plates are fixedly connected. According to the positioning device, the structure is compact,with the characteristics of reasonable structural design and high degree of
automation, the translation mechanism can stir a horizontal cover plate in the feeding and discharging mechanism to move back and forth when being specifically used, the feeding and discharging mechanism, cooperating with the adsorption mechanism, can realize the carrying process of the
semiconductor devices, and the limit mechanism can accurately positioning the
semiconductor parts from four directions.
