[0002] The semiconductor manufacturing industry has extremely stringent requirements for the processing of high-purity metal wires (such as gold wires and copper alloy wires), which must ensure the uniformity of material composition and the compactness of microstructure. In the existing technology, metal wire preparation usually adopts a step-by-step processing technology: first, solid raw materials are heated to a molten state through melting equipment to form liquid metal, and then the liquid metal is transferred to forming equipment, and solidified and shaped into the target wire diameter using mold casting or continuous drawing process.

[0003] However, the above-mentioned sequential processing mode has significant drawbacks in practical applications. The separation of equipment for smelting and forming processes leads to production interruptions. During the transfer process, liquid metal is prone to secondary pollution due to contact with air or container walls, which affects the internal purity of the wire and restricts the yield rate of high-end applications such as semiconductor packaging and bonding.

[0030] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0031] Please refer to Figures 1-5 .

[0032] The present invention discloses a smelting and continuous casting equipment for processing metal wire, comprising a smelting mechanism 1, a locking mechanism 4, a guide rod 7, a worktable 6, and a traction mechanism 8.

[0033] The melting mechanism 1 includes a cylinder body 11 and a cylinder head 17. A first interlayer 111 is formed in the side wall of the cylinder body 11, and a second interlayer 171 is formed in the side wall of the cylinder head 17. Both the first interlayer 111 and the second interlayer 171 are connected to a water inlet pipe and a water outlet pipe. The water inlet pipe is far away from the water outlet pipe. Both the water inlet pipe and the water outlet pipe are connected to an external water supply mechanism. The external water supply mechanism generates flowing water in the first interlayer 111 and the second interlayer 171 through the two water inlet pipes and the two water outlet pipes respectively, thereby reducing the temperature of the cylinder body 11 and the cylinder head 17.

[0034] A mounting base 112 is fixedly connected inside the cylinder body 11. In this embodiment, the mounting base 112 is preferably a hollow annular structure so that the mounting base 112 can hold the crucible. A crucible is placed on top of the mounting base 112. A base 121 is fixedly connected to the bottom of the crucible. The base 121 is inserted into the center of the mounting base 112. A liquid guiding block 122 passes through the base 121. A drain hole is opened at the bottom of the crucible. The drain hole passes through the liquid guiding block 122 and the bottom of the crucible. The drain hole is arranged vertically. A heat-conducting layer 123 covers the outside of the crucible.

[0035] Furthermore, a heating assembly 13 is provided inside the cylinder 11, which surrounds the outside of the crucible. The heating assembly 13 includes an electrical box and a heating coil 132.

The heating seat 131 is fixedly connected to the electrical box and extends into the cylinder 11. An external power supply is electrically connected to the heating seat 131. The two ends of the heating coil 132 are electrically connected to the two heating seats 131 respectively, and the heating coil 132 surrounds the outside of the crucible. When the metal raw material is placed into the crucible, the external power supply powers the heating coil 132 through the heating seat 131, thereby allowing the heating coil 132 to perform gradient heating on the crucible until the metal phase changes to liquid.

[0036] The cylinder body 11 has a cooling seat 14 at the bottom, a positioning groove at the top of the cooling seat 14, and a heat insulation plate 141 covering the top of the cooling seat 14. In this embodiment, the heat insulation plate 141 is preferably a hollow annular structure.

[0037] Furthermore, a mounting bracket 15 is fixedly connected to the bottom of the cylinder body 11, and a guide tube 152 is fixedly connected to the mounting bracket 15. One end of the guide tube 152 is aligned with the forming hole, and the forming hole and the guide tube 152 are coaxial. A second spring seat 84 is fixedly connected to the mounting bracket 15, and a temperature detection device 151 is slidably connected to the second spring seat 84. One end of the temperature detection device 151 passes through the cooling seat 14 and the heat insulation plate 141 in sequence and touches the bottom of the base 121. The temperature detection device 151 is used to monitor the temperature of the crucible in real time. A second spring is sleeved on the outside of the temperature detection device 151. The two ends of the second spring touch the second spring seat 84 and the temperature detection device 151 respectively. The second spring pushes the temperature detection device 151 to slide upward on the second spring seat 84 and touch the base 121.

[0038] Furthermore, a first observation window 16 is connected to the cylinder body 11, which faces the mounting base 112, making it easy for workers to check whether the crucible is accurately placed on the mounting base 112; a cylinder cover 17 is placed on the cylinder body 11, and a second observation window 172 is connected to the cylinder cover 17, which faces the inside of the crucible, making it easy for workers to check the melting of the metal raw materials.

[0039] A lifting assembly 2 is provided on the cylinder cover 17. A stirring assembly 3 is slidably connected to the lifting assembly 2. The stirring assembly 3 passes through the cylinder cover 17 and is placed inside the crucible. The lifting assembly 2 includes a lead screw device 21. The lead screw device 21 is fixedly connected to the top of the cylinder cover 17. The lead screw device 21 is arranged vertically. A slide block 211 is slidably connected to the lead screw device 21. The stirring assembly 3 is fixedly connected to the slide block 211.

[0040] The stirring assembly 3 includes a stirring motor 31 and a stirring rod 311. The stirring motor 31 is fixedly connected to the slide 211. The output shaft of the stirring motor 31 is fixedly connected to one end of the stirring rod 311. The top of the cylinder cover 17 is provided with a second sealing seat 173. The other end of the stirring rod 311 passes through the second sealing seat 173 and is placed inside the crucible. The stirring motor 31 drives the other end of the stirring rod 311 to rotate inside the crucible, thereby stirring the liquid metal inside the crucible.

[0041] A propulsion cylinder 41 is fixedly connected to the outer side of the cylinder body 11. The output shaft of the propulsion cylinder 41 is rotatably connected to the cylinder head 17. A limit groove 174 is provided on the outer side of the cylinder head 17. A locking mechanism 4 is fixedly connected to the cylinder body 11 and detachably connected to the cylinder head 17. The locking mechanism 4 includes a locking cylinder 42. The locking cylinder 42 is fixedly connected to the outer side of the cylinder body 11. A locking wheel 421 is fixedly connected to the output shaft of the locking cylinder 42. An annular groove is provided on the outer side of the locking wheel 421. The annular groove of the locking wheel 421 is inserted into the limit groove 174 and detachably connected.

[0042] When the cylinder cover 17 is opened, the output shafts of the propulsion cylinder 41 and the locking cylinder 42 rise synchronously a certain distance, opening the cylinder cover 17 from the cylinder body 11. Simultaneously, the lead screw device 21 pulls the stirring rod 311 upward, pulling the stirring rod 311 out of the crucible and the cylinder body 11. The cylinder cover 17 is pushed to rotate horizontally at a certain angle on the output shaft of the propulsion cylinder 41, causing the limiting groove 174 of the cylinder cover 17 to disengage from the constraint of the locking wheel 421, thereby opening the cylinder body 11 and facilitating the placement of metal raw materials into the crucible.

[0043] When the cylinder head 17 is closed, it is pushed to rotate horizontally at a certain angle on the output shaft of the push cylinder 41 and move to the top of the cylinder body 11. The locking wheel 421 is engaged in the limiting groove 174. The annular groove of the locking wheel 421 and the limiting groove 174 of the cylinder head 17 form an axial constraint. The output shaft of the push cylinder 41 and the output shaft of the locking cylinder 42 pull the cylinder head 17 down and cover the cylinder body 11. When the output shaft of the locking cylinder 42 is pulled, the locking wheel 421 and the output shaft of the push cylinder 41 pull the cylinder head 17 at the same time, applying a vertically downward locking force to the cylinder head 17, thereby sealing the cylinder body 11 with the cylinder head 17.

[0044] Please refer to Figure 1 , Figure 3 and Figure 5 .

[0045] A vacuum chamber 5 is fixedly connected to the bottom of the cylinder body 11. The bottom of the cooling seat 14 extends into the vacuum chamber 5. The vacuum chamber 5 is equipped with four cooling pipes 51. One end of each cooling pipe 51 is connected to the interface of the cooling seat 14, and the other end extends out of the vacuum chamber 5 and is connected to an external refrigeration device. The external refrigeration device continuously injects low-temperature cooling water into the cooling seat 14 through two of the cooling pipes 51. The high-temperature cooling water in the cooling seat 14 flows back to the external refrigeration device through the other two cooling pipes 51, thereby forming a flowing water flow to reduce the temperature of the cooling seat 14.

[0046] Furthermore, the vacuum chamber 5 is connected to an extraction pipe 52, which is connected to an external extraction device. The external extraction device uses the extraction pipe 52 to evacuate the vacuum chamber 5 to a vacuum state. Both the cylinder 11 and the vacuum chamber 5 are connected to an air inlet pipe 53, which is connected to an external gas injection mechanism. When the equipment is running, the external gas injection mechanism injects inert gas into the cylinder 11 and the vacuum chamber 5 through the two air inlet pipes 53 respectively, to solve the oxidation reaction that occurs in the metal raw materials during smelting and to perform anti-oxidation treatment on the metal wire after the drawing process has solidified.

[0047] Furthermore, a third observation window 54 is connected to the vacuum chamber 5, which faces downwards from the cooling base 14, making it easy for workers to observe the progress of the metal wire curing process; the vacuum chamber 5 is fixedly connected to the top of the workbench 6.

[0048] Please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7 .

[0049] A first sealing seat 61 is fixedly connected inside the workbench 6. Both the first sealing seat 61 and the second sealing seat 173 have through holes, and a sealing ring is provided on the inner wall of the through hole. One end of the guide rod 7 passes through the through hole of the first sealing seat 61 and the forming hole of the cooling seat 14 in sequence, touching the top of the drain hole. The sealing ring of the first sealing seat 61 is sleeved on the outside of the guide rod 7 to prevent outside air from entering the vacuum box 5 through the through hole of the first sealing seat 61. The sealing ring of the second sealing seat 173 is sleeved on the outside of the stirring rod 311 to prevent outside air from entering the cylinder 11 through the through hole of the second sealing seat 173.

[0050] Furthermore, a threaded hole 71 is provided at one end of the guide rod 7. Liquid metal flows into the threaded hole 71 at the end of the guide rod 7 through the drain hole. Under the cooling effect of the cooling seat 14, it solidifies in the threaded hole 71 to form a mechanical interlocking structure. This can improve the adhesion of the metal wire after the guide rod 7 is pulled and solidified, prevent the metal wire from detaching from the guide rod 7 when it is pulled, and also make it easier to remove the guide rod 7 from the metal wire.

[0060] This equipment employs an integrated two-stage metal wire manufacturing process;

[0061] The first stage of the melting and casting process: After the metal raw material is placed into the crucible, the cylinder cover 17 is reset. The cylinder cover 17 is pulled by the output shaft of the pushing cylinder 41 and the output shaft of the locking cylinder 42 to achieve airtight sealing, thereby sealing the cylinder cover 17 onto the top of the cylinder body 11. Inert gas is injected through the air inlet pipe 53 of the cylinder body 11 to prevent oxidation reaction of the metal raw material during melting. By energizing the heating coil 132, the heating coil 132 performs gradient heating on the crucible, heating the metal into a liquid state.

[0062] The next stage finishing process: The external vacuum equipment evacuates the vacuum box 5 to a vacuum state through the vacuum pipe 52, and then injects inert gas into the vacuum box 5 through the air inlet pipe 53 to perform anti-oxidation treatment on the metal wire solidified by the drawing process; the external cooling equipment injects cooling water into the cooling base 14 through the cooling pipe 51 to reduce the temperature of the guide rod 7, and the liquid metal will flow into the drain hole and the threaded hole 71 of the guide rod 7 and solidify.

[0063] The traction motor 83 drives the first contact wheel 822 to rotate, pulling the guide rod 7 down and slowly pulling it out from the cooling seat 14 and the first sealing seat 61. During the process of the guide rod 7 being pulled out of the forming hole, liquid metal continuously flows through the drain hole and enters the forming hole. The cooling seat 14 cools the liquid metal to solidify and form the metal wire. Under the pull of the guide rod 7, the metal wire passes through the cooling seat 14, the first sealing seat 61, the air injection seat 86 and the traction mechanism 8 in sequence. The air injection seat 86 performs a secondary anti-oxidation treatment on the metal wire. Finally, the guide rod 7 is removed from the metal wire and wound up in the external winding mechanism, thus completing the processing.

[0064] This utility model provides a smelting and continuous casting equipment for processing metal wires, which implements an integrated two-stage metal wire manufacturing process;

[0065] The first stage of the melting and casting process: After the metal raw material is placed into the crucible, the cylinder cover is sealed on the top of the cylinder body and the airtightness is achieved through the locking mechanism. Inert gas is injected through the air inlet pipe of the cylinder body to solve the oxidation reaction of the metal raw material during melting. The heating component performs gradient heating on the crucible until the metal is heated to a liquid state.

[0066] The next stage of finishing process: External vacuum equipment evacuates the vacuum chamber to a vacuum state through the vacuum pipe, and then injects inert gas into the vacuum chamber through the air inlet pipe to perform anti-oxidation treatment on the metal wire solidified by the drawing process; External cooling equipment injects cooling water into the cooling seat through the cooling pipe to reduce the temperature of the lead rod, and the liquid metal flows into the drain hole to contact and solidify at one end of the lead rod. The traction mechanism pulls the lead rod down and slowly extracts it from the cooling seat and the first sealing seat; During the process, the liquid metal rapidly cools and solidifies into a metal wire as it passes through the cooling seat. Under the pull of the lead rod, it passes through the cooling seat, the first sealing seat and the traction mechanism in sequence, and then the lead rod is removed from the metal wire and wound into the external winding mechanism, thus completing the processing; This achieves two metal wire processing steps in a single production, thereby improving the internal purity of the wire.
