Description

Technical Field

[0001] The present application relates to the technical field of metal wire drawing, and in particular to a metal wire drawing method, device, equipment and medium. Background Art

[0002] As the quality requirements for fine metal wires continue to increase across various industries, the wire drawing process is evolving towards higher precision and improved performance. During wire drawing, the metal wire is passed through a drawing die with a smaller aperture than the wire diameter. The wire is then drawn through the die to reduce the diameter, ultimately becoming a micron-thin wire for use in semiconductor packaging.

[0003] Before a metal wire passes through a wire drawing die, its head diameter must be reduced to allow it to pass through the die. This process is called point rolling. Currently, metal wires are generally pointed using a core rolling mill, which involves machining rows of slots on upper and lower rollers. The slots are arranged from large to small, and the diameter of each hole gradually decreases from large to small according to the reduction ratio. The wire head is then inserted into the larger portion of the slot, and as the rollers rotate, the wire head diameter is gradually reduced. The disadvantages of this method are: (1) the rolling of the tip is not continuous. If you want to obtain a larger diameter reduction ratio, you need to go through multiple slots and repeat the operation; (2) the wire needs to be rotated continuously, because the slots are formed by fitting the holes of the upper and lower rollers, and there must be a gap in the middle. If the wire is not rotated, the diameter reduction effect of the wire in the vertical direction will be poor, while the diameter reduction effect in the left and right directions will be poor, and even the cobra-like flash phenomenon will appear. Rotating the wire not only increases the workload but may also damage the metal wire by twisting it continuously; (3) the surface of the wire is damaged by the rolling of the tip. Because the wire is rolled by continuously rotating the wire multiple times, it is easy to cause unevenness, wrinkles, bends and other defects on the wire surface. This leads to low wire drawing efficiency. Summary of the Invention

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of illustration and description and are not used to limit the scope of protection of the present application.

[0049] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0050] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0051] In view of the technical problems raised by the background technology, the present application provides a metal wire drawing method, device, equipment and medium, which can select a rolling tip structure with adaptive structural parameters according to the initial wire diameter, target wire diameter and drawing die of the metal wire to be drawn, and quickly reduce the head wire diameter of the metal wire so that it can pass through the drawing die for drawing and diameter reduction, thereby improving the metal wire drawing efficiency.

[0052] In one embodiment, see the attached Figure 1The present application provides a metal wire drawing method, which is applied to a sharpening structure for metal wire drawing, wherein the sharpening structure includes a tapered roller rotating frame and a tapered roller assembly, wherein the tapered roller assembly includes two tapered rollers symmetrically mounted on the tapered roller rotating frame; wherein, when the tapered roller rotating frame is driven to rotate with the tapered roller assembly, a tapered tapered space is formed between the two tapered rollers, which is used to reduce the diameter of the head of the metal wire passing through the tapered tapered space. The method comprises the following steps:

[0053] S1. Select a metal wire to be drawn, and select a suitable drawing die according to a target wire diameter of the metal wire; wherein the diameter of the sizing zone of the selected drawing die is equal to the target wire diameter;

[0054] S2. Selecting a rolling tip structure with matching structural parameters according to the initial wire diameter, the target wire diameter, and the length of the sizing zone of the drawing die;

[0055] S3. After the wire diameter of the head of the metal wire is reduced based on the pointed structure, the wire is passed through the sizing area of ​​the drawing die to be drawn and reduced in diameter.

[0056] In order to clearly understand the technical solution of the embodiment of the present application, the tipping structure of the metal wire drawing used in the present application can be described first. Figure 2 and instructions attached Figure 3 In one embodiment, the rolling point structure mainly consists of a casing 2 and a conical roller assembly and a conical roller rotating frame 7 arranged inside the casing 2; the conical roller assembly includes two conical rollers 5 symmetrically mounted on the conical roller rotating frame 7; wherein, one end of the conical roller rotating frame 7 is connected to the motor 14, and the other end is connected to the large bottom end of the conical roller 5 through the conical roller bottom end bearing 6. The casing 2 is provided with an internal gear ring 3 at the end facing the entrance of the metal wire 1, and a channel for passing the metal wire 1 is left in the middle, and the small bottom end of the conical roller 5 is meshed with the internal gear ring 3 through a conical roller gear 4. When the motor 14 drives the conical roller rotating frame 7 to rotate, the two conical rollers 5 revolve around the rotating axis of the conical roller rotating frame 7 and rotate at the same time, and fit into a rolling point conical space 17 to reduce the wire diameter of the head of the metal wire 1.

[0057] For details, see the attached manual. Figure 2 and instructions attached Figure 4The conical roller rotating frame 7 is installed on the bearing support frame provided in the casing 2 through the rotating frame bearing, and is meshed with the driving gear 13 connected to the output end of the motor 14 through the rotating frame gear 10. When the motor 14 is started, the driving gear 13 is driven to rotate, and the driving gear 13 drives the rotating frame gear 10 meshed with it to rotate, and the rotating frame gear 10 drives the conical roller rotating frame 7 to rotate.

[0058] To improve the rotational stability and precision of the tapered roller rotating frame 7, it is preferable to use multiple rotating frame bearings. This is because if there is only one rotating frame bearing, all the load (the tapered roller rotating frame 7 itself and the tapered rollers 5 it drives) is concentrated at this single point, which can easily lead to local overload of the bearing, affecting its service life and rotational stability. Furthermore, rotational instability is often accompanied by vibration, which in turn affects the precision of the subsequent tapered roller rotating frame 7 driving the tapered rollers 5 to rotate and sharpen the metal wire. In one embodiment, the rotating frame bearing includes a first rotating frame bearing 9 and a second rotating frame bearing 12. The bearing support frame includes a first bearing support frame 8 and a second bearing support frame 11, which are spaced apart. The first rotating frame bearing 9 is connected to the first bearing support frame 8, and the second rotating frame bearing 12 is connected to the second bearing support frame 11. This distributes the load (the tapered roller rotating frame 7 itself and the tapered rollers 5 it drives) between two support points, providing stable support, avoiding vibration caused by instability, and ensuring the rotational precision of the tapered roller rotating frame 7.

[0059] See the instructions attached Figure 5 The tapered roller rotating frame 7 comprises a rotating shaft and a rotating disc fixed together. The rotating disc has a slotted hole on the side facing the inner gear ring 3 and near the edge. A fixed shaft is provided at the large bottom end of the tapered roller 5. The fixed shaft is mounted in the slotted hole via a bearing 6 at the bottom end of the tapered roller. Two slotted holes are arranged symmetrically about the rotation center of the tapered roller rotating frame 7, for mounting two symmetrically arranged tapered rollers.

[0060] See the instructions attached Figure 6 The inner gear ring 3 is disposed at the end of the housing 2 facing the inlet of the metal wire 1. A circular hole is provided in the center of the inner gear ring 3 for mounting the tapered roller gear 4 and for passing the metal wire 1 through. The inner gear ring 3 is also provided with a flange for mounting the inner gear ring 3 to the housing 2. The small bottom end of the tapered roller 5 is meshed with the inner gear ring 3 through the tapered roller gear 4.

[0061] See the instructions attached Figure 7To improve the structural rigidity and motion stability of the tapered roller 5 during orbital rotation, a supporting force directed outward from the center axis of rotation is applied to the lower end of the tapered roller 5. This, together with the tapered roller bottom bearing 6, supports the tapered roller 5, improving its structural rigidity and motion stability during orbital rotation. A support inner ring 15 is provided at the end of the housing 2 facing the inlet of the metal wire 1. This support inner ring 15 has a center hole for the metal wire 1 to pass through, and an outer cylindrical surface centered around the rotation center of the tapered roller rotating frame 7. The tapered roller top bearing 16 is mounted on the fixed shaft of the tapered roller 5. The outer cylindrical surface of this bearing 16 is tangential to the outer cylindrical surface of the support inner ring 15. When the tapered roller 5 orbits around the rotation center of the tapered roller rotating frame 7, the outer cylindrical surface of the bearing 16 presses against the outer cylindrical surface of the support inner ring 15 as it rotates, improving the structural rigidity and motion stability of the tapered roller 5. The supporting inner ring 15 is further provided with a flange for mounting the supporting inner ring 15 on the housing 2 .

[0062] When the motor 14 drives the tapered roller rotating frame 7 to rotate, the tapered roller 5 revolves around the rotating axis of the tapered roller rotating frame 7. Since the tapered roller 5 is engaged with the inner gear ring 3, while the tapered roller 5 revolves around the rotating axis of the tapered roller rotating frame 7, the tapered roller 5 also rotates on its own. When the tapered roller 5 rotates at high speed, a tapered space 17 for rolling is fitted. When the head of the metal wire is inserted, a pointed tip can be processed through the continuous rotation, extrusion or grinding of the tapered roller 5, thereby achieving the purpose of rolling. Among them, the tapered roller assembly can be provided in one set or in two or more sets symmetrically. Although providing multiple sets of tapered roller assemblies increases the cost compared to providing one set of tapered roller assemblies, it can improve the efficiency of metal wire rolling. The number of tapered roller assemblies to be provided is selected according to the specific application requirements, and this application does not limit or fix this.

[0063] In step S1, a suitable drawing die is selected specifically according to the target wire diameter of the metal wire to be drawn. For example, in one embodiment, the metal wire to be drawn is a bonding wire blank rod, which is the original material for manufacturing bonding wires. Bonding wire is a thin metal wire widely used in the electronic industry such as semiconductor packaging, and is mainly used to achieve electrical connection between the chip and the packaging substrate. The bonding wire blank rod is drawn into a thin wire that meets the bonding requirements through a wire drawing process. For example, in semiconductor packaging, the diameter of the bonding wire may be between a dozen microns and several dozen microns depending on the different requirements of the chip. The structure of the drawing die is shown in the attached manual. Figure 8As shown, it mainly consists of a compression zone including an inlet and a sizing zone including an outlet, wherein the inlet has a larger aperture to facilitate the smooth entry of the metal wire into the drawing die, and the aperture of the compression zone gradually decreases to gradually reduce the diameter of the metal wire; the sizing zone determines the diameter of the metal wire finally drawn, and the aperture of the outlet is larger than the aperture of the sizing zone, so that the drawn metal wire can smoothly leave the drawing die to avoid scratches or deformation. Therefore, the aperture of the sizing zone of the drawing die should be equal to the target diameter of the drawn metal wire. It should be noted that in order to help maintain the stability of the process throughout the drawing process, the target diameter of the metal wire is between 85% and 95% of the original wire diameter, that is, the diameter reduction ratio is in the range of 5% to 15%, to avoid problems such as uneven wire diameter and easy breakage due to excessive diameter reduction.

[0064] In step S2, when selecting a pointed structure with adapted structural parameters, the following conditions need to be met: the head of the metal wire after pointed can smoothly pass through the sizing area of ​​the selected drawing die, and a certain length must be reserved to facilitate clamping and pulling it outward.

[0065] In one embodiment, the length of the sizing zone of the selected drawing die is , the length of the metal wire head extending out of the drawing die is , the initial wire diameter of the metal wire is , the target wire diameter of metal wire drawing is The structure of the tapered space formed by the rotation of the tapered roller is shown in the attached manual. Figure 9 As shown, the maximum diameter of the tapered space fitted by the pointed structure is The minimum diameter of the tapered space fitted by the pointed structure is .

[0066] If the metal wire can be smoothly inserted into the tapered space formed by the rotation of the tapered roller in the rolling structure, it is necessary to ensure the maximum diameter of the tapered space. Larger than the initial wire diameter of the metal wire Since the head of the metal wire is formed into a conical structure by the pointed structure, and the minimum diameter of the conical structure is the minimum diameter of the pointed conical space , the maximum diameter is the initial wire diameter of the metal wire , and because the initial wire diameter of the metal wire Larger than the diameter of the sizing zone of the drawing die , so in satisfying When the tip of the metal wire is pointed, it is also necessary to ensure that the conical structure formed by the pointed structure is from the minimum diameter To diameter The length between them is greater than or equal to the length of the sizing zone of the selected drawing die The length of the metal wire head extending out of the drawing die The head of the metal wire is formed into a tapered structure by the rolling structure from the minimum diameter To diameter The length between the two is obtained by the taper angle of the tapered roller in the rolling point structure, and the calculation formula is: Therefore, this application selects the tipping structure with the appropriate structural parameters through the following formula: , .

[0067] In this application, the initial wire diameter of the metal wire is 10 mm or more. ≥0.5mm. On the one hand, when the wire diameter of the metal wire is within this range, it can adapt to the application needs of most fields in the market. On the other hand, if the wire diameter is too large, such as exceeding 10mm, the purchase cost of raw materials will increase, and more waste may be generated during the wire drawing process. Because the deformation amount of each drawing is relatively limited, the material utilization rate may not be high enough to meet most people's needs. If the wire diameter is too small, such as less than 0.5mm, more precise and special molds and equipment are required to ensure the smooth progress of the drawing process. For example, the accuracy of the mold aperture may need to be controlled at the micron level, and parameters such as the equipment's tension control also need to be more finely adjusted, which increases the cost.

[0068] It should be noted that, in the rolling point structure, the surface of the tapered roller may be a hard material, a sprayed abrasive or a blade. When the surface of the tapered roller is a hard material, the head wire diameter of the metal wire is extruded into a cone based on the rolling point structure; when the surface of the tapered roller is a sprayed abrasive, the head wire diameter of the metal wire is ground into a cone based on the rolling point structure; when the surface of the tapered roller is a blade, the head wire diameter of the metal wire is turned into a cone based on the rolling point structure.

[0069] In step S3, after selecting the appropriate wire drawing die and rolling point structure, the head of the metal wire is inserted into the rolling point conical space fitted by the rotating conical roller in the rolling point structure for rolling point, and then the head of the pointed metal wire is passed through the sizing area of ​​the wire drawing die for drawing and diameter reduction.

[0070] It can be seen that the metal wire drawing method provided in the present application utilizes a designed rolling point structure to fit a rolling point conical space through the rotation of a conical roller, thereby reducing the wire diameter of the head of the metal wire. In this way, a rolling point structure with matching structural parameters can be selected according to the initial wire diameter, target wire diameter and drawing die of the metal wire to be drawn, and the rolling point can be completed quickly. The wire can then be passed through the drawing die for drawing and diameter reduction, thereby improving the efficiency of metal wire drawing.

[0071] Based on the same inventive concept, a metal wire drawing device is also provided in an embodiment of the present application. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above-mentioned metal wire drawing method in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0072] As the instruction manual Figure 10 As shown, an embodiment of the present application provides a metal wire drawing device, which is applied to a sharpening structure for metal wire drawing. The sharpening structure comprises a tapered roller rotating frame and a tapered roller assembly, wherein the tapered roller assembly comprises two tapered rollers symmetrically mounted on the tapered roller rotating frame; wherein, when the tapered roller rotating frame is driven to rotate with the tapered roller assembly, a tapered tapered space is fitted between the two tapered rollers, which is used to reduce the wire diameter of the head of the metal wire passing through the tapered tapered space; the device comprises:

[0073] The first selection module 1001 is used to select a metal wire to be drawn and select a suitable drawing die according to a target wire diameter of the metal wire; wherein the diameter of the sizing zone of the selected drawing die is equal to the target wire diameter;

[0074] A second selection module 1002 is configured to select a tipping structure that matches the structural parameters according to the initial wire diameter, the target wire diameter, and the length of the sizing zone of the drawing die;

[0075] The drawing module 1003 is used to reduce the diameter of the head of the metal wire based on the point rolling structure, and then pass the wire through the sizing area of ​​the drawing die to perform drawing and diameter reduction.

[0076] In one embodiment, the second selection module 1002 selects a tipping structure that matches the structural parameters using the following formula:

[0077]

[0078]

[0079] in, Indicates the initial wire diameter of the metal wire, Indicates the target wire diameter of metal wire drawing. represents the maximum diameter of the tapered space fitted by the pointed structure, It represents the minimum diameter of the tapered space fitted by the pointed structure. represents the taper angle of the tapered roller in the rolling point structure, Indicates the length of the sizing zone of the drawing die, Indicates the length of the metal wire extending from the drawing die.

[0080] The present application provides a metal wire drawing device, which is applied to a pointed structure for metal wire drawing. The pointed structure can fit a pointed conical space through the rotation of a conical roller, and then select an appropriate drawing die according to the target wire diameter of the metal wire drawing, as well as the initial wire diameter, target wire diameter and sizing zone length of the drawing die, and select an appropriate pointed structure. After the head wire diameter of the metal wire is reduced based on the pointed structure, it is passed through the sizing zone of the drawing die for drawing and diameter reduction, thereby improving the drawing efficiency.

The electronic device 1100 optionally includes a user interface 1103, including a display (e.g., a touch screen, LCD, CRT, holographic imaging (Holographic) or projector (Projector), etc.), a keyboard or a pointing device (e.g., a mouse, trackball (trackball), touchpad or touch screen, etc.).

[0082] The memory 1105 may include a read-only memory and a random access memory, and provides instructions and data to the processor 1101. A portion of the memory 1105 may also include a non-volatile random access memory (NVRAM).

[0083] In some embodiments, the memory 1105 stores the following elements, executable modules, or data structures, or a subset or extension thereof:

[0084] Operating system 11051, including various system programs for implementing various basic services and processing hardware-based tasks;

[0085] The application module 11052 includes various application programs, such as a launcher, a media player, and a browser, and is used to implement various application services.
