Description

Technical Field

[0001] The utility model relates to the technical field of bonding wire processing, in particular to a continuous annealing device for bonding wire processing. Background Art

[0002] The progress of modern microelectronics packaging industry has put higher and higher requirements on high performance and low cost of bonding wire. Due to its superior performance and cost, bonding wire has gradually become a new type of wire bonding material, and has broad application prospects in LED chip packaging and IC packaging. The continuous annealing heat treatment, intermediate annealing heat treatment and rewinding process of bonding wire are important process links in the production of bonding wire, which determine the final performance of bonding wire.

[0003] However, the existing bonding wires lack the ability to recover the waste heat generated during annealing, which easily causes unnecessary waste heat loss and cannot be well recycled and utilized, thereby increasing waste heat waste and reducing the full utilization of resources. In addition, after the bonding wires are annealed, during the process of being transported by the wire feeding equipment, oil stains and dust impurities will adhere to the outer wall of the bonding wires. Direct recycling operations will cause stains to adhere to the outer wall of the finished bonding wires, affecting the quality of the bonding wires.

[0004] To this end, we propose a continuous annealing device for bonding wire processing. Utility Model Content

[0011] Preferably, support plates are symmetrically fixedly connected to the surface of the rear cover plate, and a brush cylinder is rotatably installed between the two support plates.

[0012] Preferably, a control panel is installed on one side surface of the annealing furnace, and the heating device and the water pump are electrically controlled and connected by the control panel.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by installing a heat absorbing plate and a spiral water pipe in the heat exchange box, the high-temperature air in the annealing furnace can be absorbed when the bonding wire in the annealing furnace is annealed, and when the cooling water in the water storage tank passes through the spiral water pipe, the waste heat in the high-temperature air in the heat exchange box is absorbed by the heat absorbing plate and transmitted to the cooling water in the spiral water pipe. At this time, the cooling water temperature rises and passes through the coil through the drain pipe. The heat release tube installed on the outside of the coil can release heat from the high-temperature cooling water to preheat the bonding wire in the annealing furnace. It can not only preheat the bonding wire but also reasonably utilize the excess heat in the annealing furnace, thereby achieving energy saving. BRIEF DESCRIPTION OF THE DRAWINGS
