A guide stretching device for producing bonded copper wire and its application method

Abstract

The invention discloses a material guide stretching device for producing bonded copper wire, which comprises a base, a stretching roller assembly and a winding assembly installed on the base, a guide assembly is arranged on the stretching roller assembly, and the base An electric push rod is fixedly installed on the upper end of the stretching roller assembly and directly below the stretching roller assembly. One end of the piston rod of the electric push rod is fixedly mounted with a top plate used in conjunction with the stretching roller assembly. The top plate is set as a single-sided opening A concave top plate, and a slot is provided on the side wall of the top plate, and a conflicting component for adjusting the drawing diameter of the copper wire is slidably inserted into the inside of the slot. The present invention can precisely control the diameter of the bonded copper wire after stretching by adopting the cooperation of the stretching roller assembly and the conflicting assembly, and the two ends of the stretching roller body are respectively fixedly inserted into the two sets of damping bearings. When the inner ring is stretched, when the tension is too large, the stretching roller will rotate accordingly to prevent the bonding copper wire from being broken.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a material guide stretching device for producing bonded copper wires; the invention also relates to a method for using the guide material stretching device for producing bonded copper wires. Background technique [0002] Bonding copper wire is mainly used in integrated circuits and semiconductor discrete devices. It is one of the most important components in integrated circuits and semiconductor discrete devices. In the production process of bonding copper wires, stretching is an extremely important process. , the current technology is to place the bond on the placement roller at the same time, and then draw one end of the copper wire through multiple sets of guide rollers and tension rollers in turn and then fix it on the winding roller for stretching processing, but the current technology cannot Accurately control the diameter of the copper wire, and it...
