A lead frame jumper combination device

Abstract

The present application provides a lead frame jumper combination device, including: a first conveying mechanism, a first turning mechanism, a second conveying mechanism and a second turning mechanism. The first conveying mechanism includes a first storage mechanism and a conveying plate. The first overturning mechanism is located at the end of the moving direction of the conveying plate; the first overturning mechanism includes a pair of rotating rods for turning the frame sucker on the conveying board 180°; the bottom of the frame sucker is provided with a ventilation hole; the top of the rotating rod faces The vent hole should be provided with a vent pipe. The second conveying mechanism includes a second storage mechanism and a vacuum tube, and a pipe valve is provided on one side of the jumper suction cup; the vacuum tube is provided with a suction hole corresponding to each layer of jumper suction cups in the stack; the outlet end of the second storage mechanism is along the output direction A transfer board is provided for the movement, and the first turning mechanism is located on one side of the middle section of the transfer board's moving track. The second turning mechanism is arranged at the end of the moving direction of the transfer plate. The second turning mechanism includes a rotating block, which has a high degree of automation and greatly improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of semiconductor production, in particular to a lead frame jumper assembly device. Background technique [0002] In semiconductors, a lead frame is usually used as a carrier, and then chips are bonded on each base island, and then connected by jumpers, and a package is formed using plastic, and finally cut to form a large semiconductor. At present, most of the processes for combining jumper wires and lead frames are done manually, and the combination efficiency is low; when assembling, it is necessary to frequently flip the lead frame and the suction cups of the jumper wires, and the weight of various suction cups is relatively large, so it is very time-consuming to flip the suction cups Physical strength; working for a long time will not only further reduce production efficiency, but also cause excessive fatigue of the operator. Contents of the invention [0003] In order to solve the deficiencies in the...
