[0002] Bonding silver wire is a high-performance alloy wire used for semiconductor packaging. Its main component is high-purity silver, usually containing trace amounts of other elements to improve its performance. It is used in the packaging of LED lighting and other semiconductor devices as an electrical connection between the chip and the package. Compared with traditional gold wires, bonding silver wire has a lower cost, good electrical conductivity and oxidation resistance, while maintaining excellent mechanical properties. The use of bonding silver wire can significantly reduce the packaging cost and improve the economic benefits of semiconductor products.

[0003] In the existing bonding silver wire drawing equipment, when the take-up reel collects enough finished bonding silver wire, manual operation is required to complete the process of replacing the take-up reel. This process includes first cutting the finished bonding silver wire, and then manually replacing the new take-up reel. Next, it is necessary to manually pull out a section of the bonding silver wire from the wire drawing machine and wind it around the new take-up reel for several turns to start a new winding process. Since the bonding silver wire is relatively hard, a large amount of force is required for manual pulling, which increases the operation difficulty and reduces the processing efficiency of the bonding silver wire. Summary of the Utility Model

Detailed implementation manners

[0018] The technical solution of the present utility model will be further described below in conjunction with the drawings.

[0019] A bonding silver wire drawing and forming device, as Figures 1 - 5 shown, includes a wire drawing machine 1, a support plate 2, a cylinder 3, a connecting plate 4, limiting wheels 5, a motor 6, a winding drum 7, a second electric slide rail 14, a sliding plate 15, a sliding seat 17, a thread-passing rod 18 and a rotating mechanism. The right side of the wire drawing machine 1 is fixedly connected with the support plate 2. The rear side of the support plate 2 is fixedly connected with the cylinder 3. The piston rod of the cylinder 3 is fixedly connected with the connecting plate 4. Limiting wheels 5 are installed on both the left and right sides of the connecting plate 4. Grooves are opened on the outer sides of the limiting wheels 5. The motor 6 is installed on the right side of the support plate 2. The output shaft of the motor 6 is detachably installed with the winding drum 7. When the bonding silver wire is wound in the winding drum 7, the motor 6 drives the winding drum 7 to rotate to pull the bonding silver wire, so that the bonding silver wire slides in the grooves of the limiting wheels 5. The cylinder 3 is used to move the limiting wheels 5 back and forth, so that the bonding silver wire can be evenly wound on the winding drum 7. The top of the support plate 2 is fixedly connected with the second electric slide rail 14. The slider of the second electric slide rail 14 is fixedly connected with the sliding plate 15. The rear side of the sliding plate 15 is slidably connected with the sliding seat 17. The rear side of the sliding seat 17 is rotatably connected with the thread-passing rod 18. A thread-passing hole is opened on the thread-passing rod 18. A rotating mechanism for driving the thread-passing rod 18 to rotate is connected between the sliding plate 15 and the sliding seat 17.

[0020] When enough bonding silver wire is wound on the winding drum 7, manually cut the bonding silver wire, remove the winding drum 7, and then replace it with a new winding drum 7. Pass one end of the bonding silver wire through the thread-passing hole of the thread-passing rod 18 and wind it three times, and then tie a knot in the bonding silver wire to fix it on the thread-passing rod 18. The second electric slide rail 14 drives the sliding plate 15 to move to the right, so that the sliding seat 17 moves to the right and approaches the new winding drum 7. During this process, the rotating mechanism makes the thread-passing rod 18 rotate around the outer side of the new winding drum 7, so that the bonding silver wire is wound around the new winding drum 7. Then, untie the bonding silver wire on the thread-passing rod 18, and the replacement of the winding drum 7 can be completed. There is no need to manually pull out the bonding silver wire, which improves the processing efficiency of the bonding silver wire.

[0021] As Figures 1 - 3 shown, the rotating mechanism includes a fixed rod 16, a clamping block 161, a second elastic member 151, a rack 152, and a gear 19. A fixed rod 16 is fixedly connected to the top of the support plate 2. The fixed rod 16 is located behind the second electric slide rail 14. A clamping block 161 is fixedly connected to the right side of the fixed rod 16. The fixed rod 16 is slidably connected to the sliding seat 17. A second elastic member 151 is fixedly connected between the sliding plate 15 and the sliding seat 17. The second elastic member 151 is set as a spiral spring. A rack 152 is fixedly connected to the top of the sliding plate 15. A gear 19 is rotatably connected to the front side of the sliding seat 17. The gear 19 is fixedly connected to the threading rod 18. The gear 19 meshes with the rack 152. Under the action of the rotating mechanism, it is not necessary to manually wind the pulled bonding silver wire around the take-up reel 7, further improving the processing efficiency of the bonding silver wire. When the rotating mechanism rotates the threading rod 18 along the outside of the take-up reel 7, the sliding seat 17 moves to the right and presses tightly against the clamping block 161. The sliding plate 15 moves to the right, causing the second elastic member 151 to be compressed. The sliding seat 17 slides on the sliding plate. Under the meshing action of the gear 19 and the rack 152, the threading rod 18 rotates. After winding the bonding silver wire around the take-up reel 7, the sliding plate 15 is reset by the second electric slide rail 14, the second elastic member 151 returns to its original state, the sliding seat 17 moves away from the clamping block 161, and the gear 19 rotates in the reverse direction.

[0022] As Figure 1 shown, it further includes a limiting ring 20. A limiting ring 20 is fixedly connected to the right side of the wire drawing machine 1. When the bonding silver wire is pulled out from the wire drawing machine 1, the bonding silver wire can be guided by the limiting ring 20, reducing the direct contact between the bonding silver wire and other components of the wire drawing machine 1 and reducing the risk of surface scratches or scrapes.

[0023] As Figure 1 and Figure 2 shown, it further includes a water absorption plate 21. A water absorption plate 21 is fixedly connected to the left side of the support plate 2. The water absorption plate 21 is set as two pieces of sponge that are symmetric up and down. After the bonding silver wire in the wire drawing machine 1 is pulled out, the bonding silver wire is placed between the upper and lower water absorption plates 21, and then wire drawing treatment is carried out. The water absorption plate 21 can wipe off the coolant on the bonding silver wire, prevent corrosion, improve the surface quality, and ensure the bonding reliability.

[0024] As Figure 1 , Figure 2 and Figure 4As shown in the figure, it further includes a fixed block 9, a sliding rod 8, a contact plate 81, a first elastic member 82, a button 10, a first electric slide rail 11, a cutter 12 and a fixed plate 13. The front side of the support plate 2 is fixedly connected with a fixed block 9, a first electric slide rail 11 and a fixed plate 13. A sliding rod 8 is slidably connected to the fixed block 9. The bottom of the sliding rod 8 is fixedly connected with a contact plate 81. A first elastic member 82 is fixedly connected between the contact plate 81 and the fixed block 9. The first elastic member 82 is arranged as a helical spring. A button 10 is installed on the top of the contact plate 81. When the button 10 is pressed for five seconds, the button 10 will trigger the first electric slide rail 11 to work, thereby preventing the first electric slide rail 11 from being triggered when a new take-up reel 7 is loaded. The slider of the first electric slide rail 11 is fixedly connected with a cutter 12. The fixed plate 13 is located directly below the cutter 12. The button 10 is electrically connected to the first electric slide rail 11. During the process of the take-up reel 7 winding the bonding silver wire, the contact plate 81 contacts the bonding silver wire. As the thickness of the bonding silver wire increases, the sliding rod 8 gradually slides upward, and the first elastic member 82 is compressed. When the take-up reel 7 winds enough bonding silver wire, the sliding rod 8 contacts the button 10, and the cutter 12 triggers the first electric slide rail 11 to move downward to cut off the bonding silver wire, thereby eliminating the need for manual cutting of the bonding silver wire and further improving the processing efficiency.

[0025] As Figure 1 , Figure 2 and Figure 4 shown, the contact plate 81 is U-shaped, the front and rear sides of the contact plate 81 are higher than the middle side, and the bottom of the contact plate 81 is a smooth surface to prevent damage caused by friction between the contact plate 81 and the bonding silver wire. When the take-up reel 7 is removed, the first elastic member 82 returns to its original state, causing the sliding rod 8 to move downward and reset. When a new take-up reel 7 is replaced, the U-shaped contact plate 81 can prevent the sliding rod 8 from blocking the new take-up reel 7 and ensure the normal replacement of the take-up reel 7.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
