Description
Technical Field
[0001] This utility model belongs to the field of splitting knife technology, and in particular relates to a wear-resistant aluminum wire splitting knife structure. Background Technology
[0002] Aluminum wire cutters are an indispensable tool in the aluminum wire bonding process. By applying pressure and heat, they can connect aluminum wires to chips or other structures, thereby forming an electrical connection between the chip and other structures. As a result, aluminum wire cutters have become an indispensable part of the bonding process. In order to increase the service life of the cutters, wear-resistant materials are used to make aluminum wire cutters.
[0003] During the use of the splitting knife, because the aluminum wire is connected to other structures by applying pressure and heat, when the aluminum wire is cut after connection, the aluminum wire melts to a certain extent, which makes it easy for molten aluminum to stick to the splitting knife and affect its use. In order to solve the above problems, there is an urgent need for a wear-resistant aluminum wire splitting knife structure. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that when aluminum wire is connected to other structures by applying pressure and heat during the use of a splitting knife, the aluminum wire melts and the molten aluminum easily adheres to the splitting knife when it is cut after connection, thus affecting the use of the splitting knife. Therefore, a wear-resistant aluminum wire splitting knife structure is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant aluminum wire splitting knife structure, including a robotic arm, a support rod fixedly installed at the bottom end of the robotic arm, a splitting knife provided at the bottom end of the robotic arm, a pressure rod provided at the bottom end of the robotic arm, a limiting component provided on one side of the support rod, and a scraping component provided on one side of the pressure rod;
[0006] The scraping assembly includes a mounting block, a first connecting post fixedly mounted on one side of the mounting block, a connecting frame rotatably mounted on the outer wall of the first connecting post, a second connecting post rotatably mounted on the connecting frame through a through hole at its other end, a scraper fixedly mounted on one end of the second connecting post, and a second spring fixedly mounted in a groove on one side of the mounting block.
[0007] As a further description of the above technical solution:
[0008] The mounting block is fixedly connected to the pressure rod, and the other end of the second spring is in contact with the connecting frame.
[0009] As a further description of the above technical solution:
[0010] The top surface of the scraper is in contact with the bottom surface of the chopping blade, and the connecting frame has an opening corresponding to the chopping blade.
[0011] As a further description of the above technical solution:
[0012] The limiting component includes a mounting base, which has a limiting ring slidably mounted on it via a groove on one side.
[0013] As a further description of the above technical solution:
[0014] The limiting ring has a first roller at one end, and the first roller is located in a groove opened in the mounting base.
[0015] As a further description of the above technical solution:
[0016] The limiting ring is fixedly connected to the outer wall of the chopping knife through a through hole, and a sliding rod is slidably installed on the limiting ring through a groove on one side.
[0017] As a further description of the above technical solution:
[0018] A first spring is fixedly installed at one end of the slide rod, and the other end of the first spring is fixedly connected to the limiting ring.
[0019] As a further description of the above technical solution:
[0020] The other end of the slide bar is provided with a second roller, the first spring is in a compressed state, and one side of the mounting base is fixedly connected to the support rod.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0022] 1. In this utility model, a scraper is provided inside. During the aluminum wire bonding process, the aluminum wire is transported to the bottom through the opening inside the cutter. At the same time, the mechanism inside the robotic arm pushes the cutter downward, thereby connecting the aluminum wire to the chip and other structures through the cutter. During the downward movement of the cutter, the scraper moves under force due to the inclined surface at the bottom of the cutter. When the cutter reaches the bottom, the scraper can slide to the inclined surface on one side of the cutter. After the bonding is completed and the aluminum wire is cut, the scraper can move on the bottom surface of the cutter and scrape it during the upward movement of the cutter. Through this design, after the cutter bonds and cuts the aluminum wire, the scraper can scrape the bottom of the cutter, thereby reducing the residue of molten aluminum at the bottom of the cutter and avoiding wear caused by the molten aluminum residue. The scraper can also scrape off other contaminants to prevent them from affecting the cutter.
[0023] 2. In this utility model, by setting a limiting ring inside, the limiting ring can be driven to move downward during the downward movement of the chopping blade. At the same time, due to the limiting of the second roller and the slide rod by the mounting base, the verticality of the chopping blade is ensured. Furthermore, if the chopping blade is subjected to a large external force and bends towards the support rod, the first spring can be further compressed, thereby providing a certain degree of protection for the chopping blade. Through this design, the connection between the limiting ring and the mounting base can ensure that the chopping blade can move vertically downward during the downward movement of the chopping blade, thereby ensuring that the chopping blade can be accurately bonded, thus ensuring the accuracy of the bonding. Moreover, when the chopping blade is bent towards the support rod by force, the first spring can be further compressed to reduce the impact on the chopping blade, and the chopping blade can be driven to return to its original position when the external force disappears.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-4This utility model provides a technical solution: a wear-resistant aluminum wire splitting knife structure, including a robotic arm 1, a support rod 2 fixedly installed at the bottom end of the robotic arm 1, a splitting knife 4 provided at the bottom end of the robotic arm 1, a pressure rod 6 provided at the bottom end of the robotic arm 1, a limiting component 3 provided on one side of the support rod 2, and a scraping component 5 provided on one side of the pressure rod 6.
[0032] The scraping assembly 5 includes a mounting block 51. A first connecting post 52 is fixedly mounted on one side of the mounting block 51. A connecting frame 54 is rotatably mounted on the outer wall of the first connecting post 52. A second connecting post 56 is rotatably mounted on the connecting frame 54 through a through hole at its other end. A scraper 55 is fixedly mounted on one end of the second connecting post 56. A second spring 53 is fixedly mounted in a groove on one side of the mounting block 51.
[0033] The mounting block 51 is fixedly connected to the pressure rod 6, the other end of the second spring 53 is in contact with the connecting frame 54, the top surface of the scraper 55 is in contact with the bottom surface of the chopping blade 4, and the connecting frame 54 is provided with an opening corresponding to the chopping blade 4.
[0034] The specific implementation method is as follows: During the aluminum wire bonding process, the aluminum wire is transported to the bottom through the opening inside the splitter 4. At the same time, the mechanism inside the robotic arm 1 pushes the splitter 4 to move downward, thereby connecting the aluminum wire to the chip and other structures through the splitter 4. During the downward movement of the splitter 4, the scraper 55 is moved by the force due to the inclined surface at the bottom of the splitter 4, which can drive the connecting frame 54 to rotate around the axis of the first connecting column 52 and compress the second spring 53. Thus, the second spring 53 ensures that the scraper 55 is always in contact with the splitter 4. When the splitter 4 moves to the bottom, the scraper 55 can slide to the inclined surface on one side of the splitter 4. After the bonding is completed and the aluminum wire is cut, during the upward movement of the splitter 4, the second spring 53 can push the connecting frame 54 to rotate and drive the scraper 55 to move on the bottom surface of the splitter 4 and scrape the bottom surface of the splitter 4.
[0035] The limiting component 3 includes a mounting base 36, on which a limiting ring 31 is slidably mounted through a groove on one side. One end of the limiting ring 31 is provided with a first roller 32, which is located in a groove in the mounting base 36. The limiting ring 31 is fixedly connected to the outer wall of the chopping blade 4 through a through hole in it. A sliding rod 34 is slidably mounted on the limiting ring 31 through a groove on one side. One end of the sliding rod 34 is fixedly mounted with a first spring 33, and the other end of the first spring 33 is fixedly connected to the limiting ring 31. The other end of the sliding rod 34 is provided with a second roller 35. The first spring 33 is in a compressed state. One side of the mounting base 36 is fixedly connected to the support rod 2.
[0036] The specific implementation method is as follows: During the downward movement of the chopping blade 4, the limiting ring 31 can be driven to move downward. At the same time, due to the limiting of the second roller 35 and the slide rod 34 by the mounting base 36, and because the first spring 33 is in a compressed state, the first roller 32 is made to be in close contact with the inner wall of the mounting base 36 by the thrust of the first spring 33. This ensures that the limiting ring 31 can remain vertical when it moves downward under the drive of the chopping blade 4, thereby ensuring the verticality of the chopping blade 4. Furthermore, if the chopping blade 4 is subjected to a large external force and bends towards the support rod 2, the first spring 33 can be further compressed, thereby providing a certain degree of protection for the chopping blade 4.
[0037] Working principle: During the aluminum wire bonding process, the aluminum wire is conveyed to the bottom through the opening inside the cleaver 4. Simultaneously, the mechanism inside the robotic arm 1 pushes the cleaver 4 downwards, connecting the aluminum wire to the chip and other structures. As the cleaver 4 moves downwards, the inclined surface at its bottom causes the scraper 55 to move under force, driving the connecting frame 54 to rotate around the axis of the first connecting post 52, thus compressing the second spring 53. The second spring 53 ensures that the scraper 55 remains in contact with the cleaver 4. When the cleaver 4 reaches its bottommost position, the scraper 55 slides to the inclined surface on one side of the cleaver 4. After bonding is completed and the aluminum wire is cut, the cleaver 4 moves upwards, allowing the wire to pass through... The second spring 53 pushes the connecting frame 54 to rotate, causing the scraper 55 to move on the bottom surface of the chopping blade 4 and scrape the bottom surface of the chopping blade 4. During the downward movement of the chopping blade 4, the limiting ring 31 can be driven to move downward. At the same time, due to the limiting of the second roller 35 and the slide rod 34 by the mounting base 36, and because the first spring 33 is in a compressed state, the first roller 32 is made to be in close contact with the inner wall of the mounting base 36 by the thrust of the first spring 33. This ensures that the limiting ring 31 can remain vertical when it moves downward under the action of the chopping blade 4, thus ensuring the verticality of the chopping blade 4. Furthermore, if the chopping blade 4 is subjected to a large external force and bends towards the support rod 2, the first spring 33 can be further compressed, thereby providing a certain degree of protection for the chopping blade 4.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
