Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to a conductive wire device which is frictionless with tin wires. Background Art

[0002] During the semiconductor packaging process, the pins of the compact semiconductor chip must be precisely aligned and inserted into the corresponding holes on the circuit board. Then, silicone oil is applied and hot air is treated, and the semiconductor component is connected to the circuit board using soldering packaging.

[0003] During soldering, a wire guide is used to guide the movement of the solder wire. However, conventional wire guides only have wire holes. As the solder wire passes through the guide, it rubs against the guide, causing wear and tear, which in turn produces tin powder. This wear and tear requires replacement, reducing production efficiency. Furthermore, tin powder produced by friction between the solder wire and the guide can fall onto the lead frame, causing quality issues and ultimately, product failure.

[0004] Therefore, it is necessary to provide a conductive wire device that does not rub against the tin wire to solve the above technical problems. Utility Model Content

[0029] The wire threading groove 6 is opened inside the support base 1.

[0030] Both ends of the threading groove 6 extend to the inner side surfaces of the first rotation groove 2 and the second rotation groove 4 respectively.

[0031] The first guide assembly 3 and the second guide assembly 5 both include a mounting shaft 51 , a bearing 52 and a rubber shaft 53 . The bearings 52 are fixedly mounted on both ends of the outer side of the mounting shaft 51 , and the rubber shaft 53 is fixedly mounted on the outer side of the bearing 52 .

[0032] The two first guide assemblies 3 are arranged opposite to each other, and the two second guide assemblies 4 are also arranged opposite to each other.

[0033] The two first guide components 3 are laterally arranged on the top of the two second guide components 4, and the inner side of the threading 6 is provided with a tin wire 7, and the tin wire 7 is respectively arranged in the middle of the two first guide components 3 and the two second guide components 4.

[0034] The two first guide assemblies 3 and the two second guide assemblies 5 have the same structure;

[0035] Both ends of the mounting shaft 51 of the first guide assembly 3 and the second guide assembly 5 are fixedly mounted on the inner side surfaces of the first rotation groove 2 and the second rotation groove 4, respectively, thereby playing the role of mounting the first guide assembly 3 and the second guide assembly 5;

[0036] The provision of the rubber shaft 53 can protect the tin wire 7 when guiding the tin wire 7 , thereby preventing the tin wire 7 from being damaged.

[0037] The working principle of the conductive wire device provided by the utility model without friction with the tin wire is as follows:

[0038] When in use, the tin wire 7 is passed through the first rotating groove 2, the threading groove 6 and the second rotating groove 4 respectively, and the two first guide components 3 and the two second guide components 5 are respectively located on both sides of the tin wire. When the tin wire and the guide components are in contact, the rubber shaft 53 can be rotated.

[0039] Compared with the related art, the conductive wire device provided by the present invention has the following beneficial effects:

[0040] Through the coordinated cooperation of the support base 1, the first rotating groove 2, the first guide component 3, the second rotating groove 4, the second guide component 5 and the wire threading groove 6, the tin wire 7 can be in contact with the first guide component 3 and the second guide component 5 instead of directly contacting the support base 1. In this way, wear of the device and the generation of tin powder can be effectively prevented, thereby improving production efficiency and product quality.

[0041] Second embodiment

[0042] Please refer to Figure 3 and Figure 4 Based on the first embodiment of this application, which provides a conductive wire device that is frictionless with the tin wire, the second embodiment of this application provides another conductive wire device that is frictionless with the tin wire. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the second embodiment of the present application provides a conductor device that has no friction with the tin wire. The difference is that, in a conductor device that has no friction with the tin wire, both sides of the inner side surfaces of the first rotating groove 2 and the second rotating groove 4 are provided with sliding grooves 8, and one side of the inner side surface of the sliding groove 8 is provided with a movable groove 81.

[0044] Both ends of the two first guide assemblies 3 and the two second guide assemblies 5 are fixedly installed with sliders 82, and the sliders 82 are slidably connected to the inner side of the slide groove 8. The top of the slider 82 is fixedly installed with a threaded rod 83, and the outer side of the threaded rod 83 is threadedly connected with a nut 84. The threaded rod 83 is arranged on the inner side of the movable groove 81, and the nut 84 is arranged on the side of the support seat 1.

[0045] The slider 82 is square, and two sides thereof fit in with the inner side surfaces of the slide 8, so that when in use, it can play a role in limiting the slider 82;

[0046] When the slider 82 moves, the threaded rod 83 can slide on the inner side of the moving groove 81, so that the user can subsequently rotate the nut 84 so that one side of the nut 84 abuts against the top of the support seat 1 to limit the slider 82.

[0047] The working principle of the conductive wire device provided by the utility model without friction with the tin wire is as follows:

[0048] During use, when it is necessary to limit the tin wires 7 of different sizes, the user can move the two relative guide components toward the middle. At this time, the two ends of the guide component will drive the slider 82 to slide on the inner side of the slide groove 8, and at the same time, the threaded rod 83 will move on the inner side of the movable groove 81 until the guide component moves to the side of the tin wire. After that, the user can rotate the nut 84 to make the nut 84 threadedly connected to the outer side of the threaded rod 83, so that one side of the nut 84 abuts against the top of the support seat 1, thereby limiting the guide component.

[0049] Compared with the related art, the conductive wire device provided by the present invention has the following beneficial effects:

[0050] By cooperating with each other, structures such as the slide groove 8, the movable groove 81, the slider 82, the threaded rod 83 and the nut 84, when guiding tin wires 7 of different sizes, the user can adjust the spacing between multiple guide components to facilitate the use of tin wires 7 of different sizes, thereby increasing the adaptability of the device.
