Description

Technical Field

[0001] The utility model relates to the technical field of gold bonding wire processing, in particular to a gold bonding wire rolling and bending device with an adjustment function. Background Art

[0002] Gold bonding wire is an electronic packaging material used in semiconductor packaging. It uses metal wire to weld between the semiconductor chip pins and the packaging bracket. The manufacturing process of gold bonding wire includes wire drawing, diameter expansion, diameter tightening, surface treatment, cutting and packaging. Among them, wire drawing is the most basic step in manufacturing. After the wire drawing process, the metal wire can obtain the required diameter and mechanical properties.

[0003] After searching, the patent document with announcement number: CN210547114U discloses a bonding wire bending device with adjustment function; by setting a threaded groove and an adjusting screw, personnel insert the bonding wire to be bent through the threading groove, pass through the pressure wheel, and pre-wind it on the winding wheel, one end extends out of the slot and extends into the reserved slot in the installation box. Personnel rotate the adjusting screw in the threaded groove, thereby driving the rotating shaft to press down, which is convenient for driving the pressure block to press down, and then it is convenient to clamp and fix the end of the bonding wire.

[0004] When the above device is in use, after the bonding gold wire is wound onto the reel, since the bonding gold wire at the end is not fixed on the reel, it is necessary to release the downward pressure of the pressure block again and fix the bonding gold wire on the reel. This may easily cause the rewound bonding gold wire to become loose and make it impossible to effectively rewind the bonding gold wire. Therefore, we propose a bonding gold wire winding device with an adjustment function to solve the above problem. Utility Model Content
