Abstract
Description
Technical Field
[0001] This invention relates to high-purity aluminum wire conveying technology, specifically to a high-purity aluminum wire conveying line and its manufacturing process. Background Technology
[0002] High-purity aluminum wire (typically ≥99.99%) is widely used in high-end manufacturing fields such as semiconductor packaging bonding wires, high-voltage power transmission lines, electrical connections for new energy vehicles, and precision instruments for aerospace due to its excellent conductivity, corrosion resistance, and surface properties. In these applications, the surface quality, dimensional accuracy, and conductivity of high-purity aluminum wire directly determine the reliability and lifespan of the end product. For example, 5N-grade high-purity aluminum bonding wires for semiconductor chips require a scratch-free, oxidation-free surface and a diameter tolerance controlled within ±0.5μm; the conductivity of high-purity aluminum wires used in high-voltage power transmission is extremely sensitive to temperature, with a 10°C increase in temperature causing a 4-5% decrease in conductivity, resulting in significant energy loss in long-distance power transmission.
[0003] In the production process of high-purity aluminum wire, continuous transport between processes such as wire drawing, annealing, and winding is required via conveyor lines. Existing high-purity aluminum wire conveyor lines suffer from the following technical defects: 1. During high-speed conveying, the continuous friction between the aluminum wire and the guide wheel generates a large amount of heat, causing the surface temperature of the guide wheel to rise sharply. High temperatures not only soften the surface of the high-purity aluminum wire and cause aluminum shavings to adhere, but also accelerate the oxidation and discoloration of the aluminum wire surface, severely affecting product quality. Simultaneously, high temperatures reduce the service life of the guide wheel, increasing equipment maintenance costs. Existing cooling methods are mostly external air cooling, which has low cooling efficiency and cannot effectively remove heat from the inside of the wheel body, making it difficult to meet the heat dissipation requirements of high-speed conveying.
[0004] 2. Traditional single-wheel guide structures are prone to aluminum wire deviation and jumping when conveying at high speeds or when the aluminum wire tension fluctuates, leading to production interruptions and affecting production efficiency.
[0005] This invention provides a high-purity aluminum wire conveyor and its manufacturing process to overcome the aforementioned shortcomings in the prior art. Summary of the Invention
[0006] The purpose of this invention is to provide a high-purity aluminum wire conveyor and its manufacturing process to overcome the above-mentioned shortcomings in the prior art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-purity aluminum wire conveying line, comprising a conveyor frame, wherein a plurality of guide units are equidistantly arranged on the conveyor frame along the high-purity aluminum wire conveying direction, the guide unit comprising a mounting frame fixedly installed on the upper surface of the conveyor frame, wherein a ceramic guide wheel is rotatably mounted on the inner side of the mounting frame, the ceramic guide wheel is hollow inside, and a V-shaped wire routing groove is provided on the ceramic guide wheel; Both ends of the ceramic guide wheel are fixedly connected to a hollow shaft. The hollow shaft is rotatably mounted to the mounting bracket via bearings. Both ends of the mounting bracket are fixedly mounted with connectors. The hollow shaft is rotatably connected to the ends of the connectors. The ends of the connectors on both sides that are far apart from each other are fixedly connected to a cooling air inlet pipe and a cooling exhaust pipe, respectively. The ends of the cooling air inlet pipe and the cooling exhaust pipe are equipped with the same cooling circulation mechanism. The mounting frame is equipped with an auxiliary guiding mechanism adapted to the ceramic guide wheel, which is used to assist the ceramic guide wheel in stably guiding and conveying the high-purity aluminum wire.
[0008] Furthermore, the cooling circulation mechanism includes a cold air transfer box installed on the lower surface of the conveyor frame, a heat exchange box installed below the conveyor frame, a hot air transfer box installed above the heat exchange box, the end of the cooling air inlet pipe being fixedly connected to the cold air transfer box, and the end of the cooling exhaust pipe being fixedly connected to the hot air transfer box.
[0009] Furthermore, the heat exchange box has a flow guide cavity at its end that communicates with the internal cavity. A flow guide fan is installed inside the flow guide cavity. A first air guide pipe that communicates with the flow guide cavity is fixedly installed at the end of the heat exchange box. The flow guide fan draws air from inside the heat exchange box into the first air guide pipe. The end of the first air guide pipe away from the heat exchange box is fixedly connected to a cold air transfer box. A second air guide pipe is fixedly connected between the hot air transfer box and the end of the heat exchange box away from the flow guide fan.
[0010] Furthermore, a cold air pipe is fixedly installed inside the heat exchange box along its length. Several air outlets are opened on the surface of the cold air pipe. The air inlet end of the cold air pipe is located outside the heat exchange box and is connected to an external refrigeration unit.
[0011] Furthermore, flow-damping plates are installed alternately on both sides of the inner wall of the heat exchange box. The ends of the flow-damping plates on both sides that are close to each other are inclined towards the direction of the exhaust fan, and the ends of the flow-damping plates on both sides that are close to each other are in contact with the surface of the cold air pipe.
[0012] Furthermore, an electromagnetic regulating valve is installed on the cooling air inlet pipe, a flow meter is installed at the end of the cooling air inlet pipe away from the cold air transfer box, a PLC controller is installed on the conveyor frame, and the electromagnetic regulating valve and the flow meter are both electrically connected to the PLC controller.
[0013] Furthermore, the auxiliary guiding mechanism includes vertical grooves symmetrically formed on both sides of the inner wall of the mounting frame. The inner walls of the vertical grooves on both sides are slidably connected to the same pressure plate. An adjusting electric rod is installed on the top of the mounting frame. The bottom of the telescopic end of the adjusting electric rod is fixed to the pressure plate. A bearing plate is installed on both sides of the bottom surface of the pressure plate. A pressure sensor is installed between the bearing plate and the pressure plate. The bearing plate is slidably connected to the inner side of the vertical groove. A pressure spring is fixedly connected to the bottom surface of the bearing plate. A slide is fixedly connected to the bottom end of the pressure spring. The slide is slidably connected to the inner side of the vertical groove. The same ceramic auxiliary wheel is rotatably installed between the two slides.
[0014] Furthermore, L-shaped grooves are symmetrically formed on both sides of the surface of the ceramic guide wheel, and adapter parts are symmetrically formed at both ends of the ceramic auxiliary wheel. The shape and size of the adapter parts are adapted to the L-shaped grooves.
[0015] This invention also provides a high-purity aluminum wire production process, applied to a high-purity aluminum wire conveying line as described above, comprising the following steps: S1. Equipment Pre-adjustment: Based on the diameter of the high-purity aluminum wire and the conveying parameters, the PLC controller presets the clamping pressure and cooling flow parameters; adjusts the electric rod to drive the ceramic auxiliary wheel to press down and calibrate the clamping force, starts the refrigeration unit and the duct fan, and completes the equipment pre-cooling standby.
[0016] S2. Threading and positioning: The high-purity aluminum wire is threaded into the V-shaped wire routing groove of each guide unit. The aluminum wire is positioned to prevent it from detaching by engaging and limiting the fit between the L-shaped groove of the ceramic guide wheel and the adapter of the ceramic auxiliary wheel.
[0017] S3, Closed-loop cooling and heat exchange: The external refrigeration unit continuously supplies cooling to the heat exchange box, the baffle plate extends the heat exchange time of the airflow, and the low-temperature cold air is sent into the hollow ceramic guide wheel through the first air guide pipe and the cooling air inlet pipe to cool the ceramic guide wheel and the high-purity aluminum wire in real time; the hot air after absorbing heat flows back to the heat exchange box to be cooled again, forming a closed-loop cooling cycle.
[0018] S4. Production Finishing Maintenance: Coordinate with upstream and downstream processes to complete continuous aluminum wire conveying production; after production is completed, shut down the equipment, wait for it to cool down naturally, and then clean the aluminum shavings on the surface of the ceramic guide wheel to complete equipment maintenance.
[0019] Compared with the prior art, the high-purity aluminum wire conveyor line and its manufacturing process provided by the present invention have the following beneficial effects: 1. This high-purity aluminum wire conveyor line and its manufacturing process utilize a hollow ceramic guide wheel combined with a closed-loop cold air circulation system. Low-temperature cold air is directly introduced into the wheel body for heat exchange, which can quickly remove the heat generated by the high-speed friction between the aluminum wire and the wheel body, preventing the aluminum wire surface from softening, aluminum shavings from sticking, and oxidation and discoloration due to excessive wheel body temperature. At the same time, the ceramic material itself has high wear resistance and low coefficient of friction, further reducing frictional heat generation and significantly extending the service life of the guide wheel.
[0020] 2. This high-purity aluminum wire conveyor line and its manufacturing process, through the cooperative structure of ceramic auxiliary wheels and ceramic guide wheels, combined with the locking and limiting design of L-shaped grooves and adapters, can effectively prevent the aluminum wire from deviating or jumping off during the conveying process; the pressure spring provides flexible clamping force, and with the real-time monitoring and control of the pressure sensor, it can not only ensure the straightness of the aluminum wire conveying, but also avoid scratches, deformation and cross-sectional dimension deviations on the aluminum wire surface caused by hard extrusion, thus ensuring the surface quality and precision of the high-purity aluminum wire.

[0027] Both ends of the ceramic guide wheel 21 are fixedly connected to a hollow shaft 3. The hollow shaft 3 is rotatably mounted to the mounting bracket 2 via bearings. Both ends of the mounting bracket 2 are fixedly mounted with connectors 31. The hollow shaft 3 is rotatably connected to the ends of the connectors 31.

The ends of the cooling air inlet pipe 32 and the cooling exhaust pipe 33 are equipped with the same cooling circulation mechanism.
[0028] It should be noted that the connector 31 is made of brass and has a sealed cavity inside. The end of the hollow shaft 3 extends into the sealed cavity of the connector 31 and is rotatably connected to the connector 31 through a rotary seal.

By setting the flow-damping plates 5, the residence time of high-temperature gas in the heat exchange box 41 can be extended, so that the hot and cold gases can fully contact each other for heat exchange and improve the heat exchange efficiency.

Pressure sensors are installed between pressure plates 73 and pressure plates 71. The pressure sensors are strain gauge pressure sensors with a measurement range of 0-50N and an accuracy of ±0.1N. A pressure spring 74 is fixedly connected to the bottom surface of pressure plate 73. The pressure spring 74 is made of stainless steel with an elastic coefficient of 1-2N / mm.
