Description

Technical Field

[0001] This utility model relates to the field of bonding alloy processing technology, and in particular to an annealing device for bonding alloy wire processing. Background Technology

[0002] Bonding alloy wires are mainly used in the semiconductor packaging industry. The manufacturing of alloy wires requires multiple steps. Among them, annealing can help reduce the hardness of the alloy wires and increase their elongation to meet the requirements of subsequent bonding processes.

[0003] In the prior art, such as the bonding alloy wire annealing equipment disclosed in Chinese Patent No. CN215757527U, a shell is included. An induction coil heater is installed on the inner side of the shell. A heat preservation cavity is opened inside the shell. A heat preservation plate is provided on the inner side of the heat preservation cavity. A fixed wheel is provided on the inner side of the heat preservation cavity. A horizontal plate is provided inside the heat preservation cavity. A moving wheel is installed on the outer surface of the horizontal plate. The bonding alloy wire is wound and driven by a winding wheel, so that the bonding alloy wire can pass through the induction coil heater, the heat preservation cavity and the cooling cavity in sequence. This allows for heating, heat preservation and cooling operations on the bonding alloy wire, and this process can be carried out continuously. This avoids the situation where the annealing process of the bonding alloy wire is carried out in an annealing furnace, which would prevent the annealing operation of the bonding alloy wire from being continuous. Therefore, the annealing work of the bonding alloy wire can be carried out continuously, which greatly improves the processing and annealing efficiency of the bonding alloy wire.

[0004] However, this patent still has shortcomings. In actual use, the alloy wire after the annealing furnace is directly wound by the winding wheel. However, the alloy wire is still at a high temperature at this time, and adhesion will occur during winding, which will affect the next stage of wire unwinding. Therefore, an annealing device for bonding alloy wire processing is proposed to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an annealing device for bonding alloy wire processing. By setting a cooling air box, the alloy wire can be pre-cooled before winding, preventing the alloy wire from sticking together during winding.

[0006] The technical solution to achieve the purpose of this utility model is: an annealing device for bonding alloy wire processing, comprising an annealing furnace and a cooling air box, wherein corresponding positions of the annealing furnace and the cooling air box are provided with through slots for alloy wire to pass through, and further comprising,

[0007] An adjustable guide bracket is installed inside the cooling air box, and a guide wheel is rotatably connected to the top of the adjustable guide bracket;

[0008] An adjustable distance assembly is disposed inside a cooling air box. The adjustable distance assembly is connected to an adjustable guide bracket and is used to adjust the relative position of the adjustable guide bracket.

[0009] A tension adjusting wheel, located above the guide wheel, is used to adjust the tension on the alloy wire wheel;

[0010] The filter box has a cooling pipe on its top, with the end of the cooling pipe away from the filter box connected to the inner cavity of the cooling air box. A filter pipe is provided on one side of the filter box, with the end of the filter pipe away from the filter box connected to the air outlet of an external industrial fan.

[0011] In some embodiments, the pitch adjustment assembly includes a smooth rod fixedly connected to the inner wall of the cooling air box, a bidirectional threaded screw rotatably connected to the inner wall of the cooling air box, and a pitch adjustment motor fixedly connected to one side of the cooling air box, the output end of the pitch adjustment motor being coaxially fixed with the bidirectional threaded screw.

[0012] In some embodiments, there are two adjustable guide brackets, both of which are threadedly connected to a bidirectional threaded screw, and both of which are slidably connected to a guide rod.

[0013] In some embodiments, a hydraulic telescopic rod is fixedly connected to the upper surface of the cooling air box, a connecting plate is fixedly connected to the output rod end of the hydraulic telescopic rod, the lower surface of the connecting plate is fixedly connected to the upper surface of the tension adjusting wheel, a balance rod is fixedly connected to the upper surface of the connecting plate, and the balance rod is slidably connected to the cooling air box.

[0014] In some embodiments, a filter frame is slidably connected to the inner bottom wall of the filter box, a partition mesh is provided on the upper surface of the filter frame, an electrostatic dust removal rod is provided on one side of the partition mesh, and an activated carbon filter layer is provided on the other side of the partition mesh.

[0015] Compared with the prior art, the significant advantages of this utility model are:

[0016] This utility model, through the filter box set after the annealing furnace, when in use, starts an external industrial fan to introduce cold air from the outside and sends the cold air into the filter box through a filter pipe. When the cold air enters the filter box, it is filtered by electrostatic dust removal rods and activated carbon filter layer. Then, the cold air is introduced into the cooling air box through a cooling pipe to cool the alloy wire, thereby preventing the alloy wire from sticking together during winding.

[0017] This solves the problem that when alloy wires are directly wound after annealing, they tend to stick together because the temperature of the alloy wires is still relatively high. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved annealing equipment for bonding alloy wire processing. The technical solution of this utility model is as follows:

[0028] like Figure 1 As shown, an annealing device for bonding alloy wire processing includes an annealing furnace 1 and a cooling air box 2. Corresponding positions in the annealing furnace 1 and the cooling air box 2 are provided with through slots for the alloy wire to pass through.

[0029] Adjustable guide bracket 3 is set inside the cooling air box 2. The top of the adjustable guide bracket 3 is rotatably connected to a guide wheel 4. There are two adjustable guide brackets 3, which are responsible for guiding the alloy wire in and out respectively.

[0030] Adjustment component 5 is installed inside cooling air box 2. Adjustment component 5 is connected to adjustable guide bracket 3 and used to adjust the relative position of adjustable guide bracket 3. Different inlet and outlet positions can make the alloy wire in the cooling air box 2 travel longer at the same time, thereby increasing the cooling time of alloy wire.

[0031] Tension adjusting wheel 6 is located above guide wheel 4 and on the central axis of the two guide wheels 4. Tension adjusting wheel 6 is used to adjust the tension on the alloy wire wheel.

[0032] To prevent external air impurities from entering the cooling box 2, a filter box 7 is installed. The top of the filter box 7 is equipped with a cooling pipe 8. The end of the cooling pipe 8 away from the filter box 7 is connected to the inner cavity of the cooling box 2. A filter pipe 9 is installed on one side of the filter box 7. The end of the filter pipe 9 away from the filter box 7 is connected to the air outlet of an external industrial fan. The filter box 7 can prevent impurities in the air from affecting the processing quality of the alloy wire.

[0033] It should be noted that the annealing furnace 1 mentioned in this application can be a conventional annealing furnace 1, such as the one mentioned in the background art. Similarly, it can be used in conjunction with the front and rear unwinding and rewinding mechanisms. Since all of the above are existing technologies, they will not be described in detail in this application, but only focus on solving the existing problems.

[0034] like Figure 2 and Figure 4 As shown, in one embodiment, a bidirectional threaded screw 502 is rotatably connected to the inner wall of the cooling box 2, and an adjustable pitch motor 503 is fixedly connected to one side of the cooling box 2. The output end of the adjustable pitch motor 503 is coaxially fixed with the bidirectional threaded screw 502. The length of the alloy wire remaining in the cooling box 2 at the same time can be adjusted by the adjustable pitch assembly 5. Specifically, the adjustable pitch motor 503 is started, and the adjustable pitch motor 503 drives the bidirectional threaded screw 502 to rotate. The distance between the two adjustable guide brackets 3 will change. With the position adjustment of the tension adjustment wheel 6, the alloy wire can receive cold air cooling for a longer time in the cooling box 2, thereby obtaining a better cooling effect.

[0035] In one embodiment, there are two adjustable guide brackets 3. Each adjustable guide bracket 3 has a threaded hole that matches the bidirectional threaded screw 502. Both adjustable guide brackets 3 are threadedly connected to the bidirectional threaded screw 502. The two adjustable guide brackets 3 are threadedly connected to the threads of the bidirectional threaded screw 502 in different directions. Each adjustable guide bracket 3 has a sliding hole that matches the smooth rod 501. Both adjustable guide brackets 3 are slidably connected to the smooth rod 501.

[0036] In one embodiment, a hydraulic telescopic rod 10 is fixedly connected to the upper surface of the cooling air box 2. A connecting plate 11 is fixedly connected to the output rod end of the hydraulic telescopic rod 10. The lower surface of the connecting plate 11 is fixedly connected to the upper surface of the tension adjusting wheel 6. A balance rod 12 is fixedly connected to the upper surface of the connecting plate 11. The balance rod 12 can prevent the tension adjusting wheel 6 from tilting and ensure the guiding effect of the tension wheel. The balance rod 12 is slidably connected to the cooling air box 2. According to the different tensions required by different alloy materials, the hydraulic telescopic rod 10 can be used to make the connecting plate 11 drive the tension adjusting wheel 6 to change its vertical position, thereby adjusting the tension of the line.

[0037] like Figure 5 As shown, in one embodiment, a filter frame 13 is slidably connected to the inner bottom wall of the filter box 7. A partition net 14 is provided on the upper surface of the filter frame 13. A vent hole is provided through the partition net 14. An electrostatic dust removal rod 15 is provided on one side of the partition net 14, and an activated carbon filter layer 16 is provided on the other side of the partition net 14.

[0038] The specific working method is as follows: When the annealing equipment for the bonding alloy wire is used, after the alloy wire annealed in the annealing furnace 1 enters the cooling air box 2, the alloy wire sequentially passes through the bottom of the guide wheel 4 near the annealing furnace 1, then through the top of the tension adjusting wheel 6, and finally exits from the bottom of the guide wheel 4 away from the annealing furnace 1. At this time, the external industrial fan is started to introduce cold air from the outside and send the cold air into the filter box 7 through the filter pipe 9. When the cold air enters the filter box 7, it is filtered by the electrostatic dust removal rod 15 and the activated carbon filter layer 16. Then, the cold air is introduced into the cooling air box 2 through the cooling pipe 8 to cool the alloy wire. After cooling, the alloy wire is then... External winding equipment can be used for winding. Depending on the tension required by different alloy materials, the vertical position of the tension adjusting wheel 6 can be changed by using the hydraulic telescopic rod 10 to drive the connecting plate 11, thereby adjusting the tension of the line. The length of the alloy wire remaining in the cooling box 2 at the same time can be adjusted by using the pitch adjustment component 5. Specifically, the pitch adjustment motor 503 is started, which drives the bidirectional threaded screw 502 to rotate. The distance between the two adjustable guide brackets 3 will change. Combined with the position adjustment of the tension adjusting wheel 6, the alloy wire can receive cold air cooling for a longer time in the cooling box 2, thereby obtaining a better cooling effect.
