The invention discloses a roll-type automatic receiving device for lead frame materials, which includes a platform, a first vertical plate, a second vertical plate, a first limit plate, a second limit plate, a first middle column, and a second middle column ; The first vertical plate and the second vertical plate are arranged on the upper end of the platform, the first limit plate and the second limit plate are arranged between the first vertical plate and the second vertical plate, and the first middle column The second middle column is coaxially arranged on the opposite surface of the first limiting disk and the second limiting disk respectively, and a plurality of sliding bars are fixed in an annular array on one side of the first middle column opposite to the second middle column. The present invention can adjust the total width of the first intermediate column and the second intermediate column / the distance between the first limiting plate and the second limiting plate, and the relative axis of each sliding plate to the first threaded rod according to the type of lead frame produced by stamping. The displacement distance is suitable for the production of lead frames of different widths and lengths, and there is no need to store multiple types of receiving barrels, which reduces production costs and saves warehouse space.
Description
technical field [0001] The invention relates to the technical field of integrated circuit processing, in particular to a roll-type automatic receiving device for lead frame materials. Background technique [0002] As the chip carrier of integrated circuits, the lead frame is a key structural part that realizes the electrical connection between the lead-out end of the chip's internal circuit and the outer lead by means of bonding materials (gold wire, aluminum wire, copper wire) to form an electrical circuit. As a bridge to connect with external wires, most semiconductor integrated blocks need to use lead frames, which are the basic materials in the electronic information industry. [0003] The lead frame is produced by die stamping method and chemical etching method, wherein the die stamping method is suitable for mass production, and the chemical etching method is suitable for new product development. The lead frame is in the shape of a sheet with a certain width during th...
