Automatic lead wire adjusting device and method thereof

Abstract

The invention discloses an automatic lead wire adjusting device and method thereof. The automatic lead wire adjusting device mainly comprises a material assembly, a lead wire adjusting assembly, a wire feeding assembly and an identification assembly, wherein the wire feeding assembly is fixed to the upper portion of the lead wire adjusting assembly, the center of a wire outlet and the center of the lead wire adjusting assembly are collinear, and the lead wire adjusting assembly comprises a plurality of adjusting tables, so that the lead wire adjusting assembly can drive the wire feeding assembly to move in the three-dimensional direction, and the flexible adjustment of the lead wire direction is automatically achieved; and the identification assembly can control the extending length of a lead wire in the wire feeding assembly according to the passing condition of the lead wire in the wire feeding assembly, and the length of the lead wire can be designed and adjusted according to the sizes of different parts. Through cooperation of the material assembly, the lead wire adjusting assembly, the wire feeding assembly and the identification assembly, the poses of a to-be-welded part and the lead wire can be automatically adjusted, the lead wire alignment adjustment precision is high, the consistency is good, the automatic lead wire adjusting device is not limited by the manual skill level, and the device is particularly suitable for the automatic production process.

Description

technical field [0001] The invention belongs to the technical field of wire bonding, and relates to a wire automatic adjustment device and a method thereof. Background technique [0002] Wire bonding realizes the excellent electrical interconnection function of microelectronic products and is widely used in the field of microelectronics. In some microelectronic products, it is necessary to weld the leads to the parts, and transmit the electrical signals of the parts through the leads. There are relatively high requirements for welding the lead wire and the part to form a component assembly. Taking the brush as an example, the end of the lead insulation layer should be close to the part to be welded, and there should be no gap between the lead wire insulation and the arm of the part to be welded, and the attachment point should be smooth. No thorns, and should not be too large, the length is required to be 1.0mm ~ 1.2mm, there must be no adhesive on the lower surface of the ...

AI Technical Summary

Problems solved by technology

[0003]At present, the production line adopts the traditional hand-held method to align the leads and parts. Due to the limitation of personnel skills, problems such as difficult alignment operations and incorrect alignment are prone to occur. Low efficiency, it is difficult to meet actual production needs

At present, there is no related technology of domestic and foreign automatic adjustment devices and methods for lead wires.
