Description

Technical Field

[0001] The utility model relates to the technical field of tinned copper wires, and more specifically, to a guiding mechanism for tinned copper wires. Background Art

[0002] A tinned copper wire is a wire with a layer of tin plated on the copper wire. The main purpose of this treatment method is to improve the oxidation resistance and rust prevention ability of the copper wire, and it also helps with wettability during the soldering process. Since copper is prone to oxidation in the air to form copper oxide, this will increase the contact resistance and affect the electrical performance. The tin layer can isolate the air and prevent the direct contact between copper and oxygen, thereby protecting the copper wire.

[0003] During the process of tin plating the copper wire, in order to make the tin on the surface of the copper wire more uniform, the tinned copper wire needs to be led out through a guiding mechanism after tin plating. In the prior art, the copper wire is led out through a guide wheel. Due to the large contact area of the guide wheel and the extrusion of the copper wire, it is easy to cause the peeling off of the tin plating layer of the copper wire. Later, it is led through a guiding die, which can effectively prevent the peeling off of the tin layer. However, in the prior art, the installation of the guiding die is either integral or fixed by bolts, etc. When the guiding die is damaged or when producing tinned copper wires with different diameters, it is difficult to replace the guiding die. Summary of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Reference Figures 1-3 , a guiding mechanism for a tinned copper wire 6, comprising: a mounting frame 1, having two vertically arranged plates 11 spaced horizontally, and concave first card slots 111 are opened at the tops of the two vertically arranged plates 11; a card board 2, and two second card slots 21 corresponding to and mating with the first card slots 111 are opened at the bottom of the card board 2; a mounting mold 3, mounted on the card board 2 and located between the two vertically arranged plates 11, having a mold cavity 31 penetrating through both ends of the mounting mold 3, and a limiting plate 32 is mounted at one end thereof, and a wire outlet hole 33 communicating with the mold cavity 31 is opened on the limiting plate 32; a guiding mold 4, embedded in the mold cavity 31 and one end abutted against the limiting plate 32, having a guiding hole 41 corresponding to the wire outlet hole 33; a positioning part 5, mounted on the vertically arranged plate 11, for limiting the top of the card board 2.

[0027] It can be understood that the mounting frame 1 is a supporting component for mounting and fixing the vertically arranged plate 11. For example, it can be a component realized by the cooperation of the bottom plate 12 and the vertically arranged plate 11 or the cooperation of other devices and the vertically arranged plate 11, etc., but not limited thereto. The vertically arranged plate 11 can be a plate-shaped or square-shaped structure, etc. The sizes of the first card slot 111 and the second card slot 21 are adapted to ensure that the card board 2 is clamped on the vertically arranged plate 11 without loosening. The shape of the mold cavity 31 is fitted with the external shape of the guiding mold 4. For example, both the mold cavity 31 and the guiding mold 4 are square or cylindrical, etc., but not limited thereto. The limiting plate 32 is a component for limiting the guiding mold 4 to prevent it from sliding out of the mold cavity 31. For example, it can be a component integrally provided with the mounting mold 3 or fixed by bolts, etc., but not limited thereto. The positioning part 5 is a component for limiting the card board 2. For example, it can be a bolt or a telescopic component abutted against the top of the card board 2, etc., but not limited thereto.

[0028] With such a setting, the mounting bracket 1 can be fixed on tin plating equipment such as a tin plating tank. After the copper wire 6 is tin plated, it passes through the guiding hole 41 at one end of the guiding die 4 away from the limiting plate 32 and then passes out through the wire outlet hole 33. Since the transmission direction of the copper wire 6 is towards the limiting plate 32, the copper wire 6 will continuously apply a force to the guiding die 4 in the direction of the limiting plate 32, and the guiding die 4 will not slide out of the guiding cavity. The embedded installation of the guiding die 4 in the guiding cavity facilitates the replacement of the guiding die 4. The cross - opening of the clamping plate 2 and the vertical plate 11 can not only firmly fix the clamping plate 2 but also make disassembly and assembly relatively convenient. Here, for replacing guiding dies 4 of different models, multiple clamping plates 2 can be pre - fabricated, and different models of guiding dies 4 are installed on the multiple clamping plates 2. In this way, when producing tin - plated copper wires 6 of different diameters, the corresponding model of the guiding die 4 can be quickly replaced according to the size of the tin - plated copper wire 6.

[0029] Reference Figures 1-2 , in some embodiments, the mounting bracket 1 further includes a bottom plate 12, and the vertical plate 11 has a fold angle, and the fold angle is stuck on the corner of the top of the bottom plate 12. It can be understood that the bottom plate 12 is a component for installing the vertical plate 11 and fixing on the tin plating equipment. For example, it can be a flat plate - like structure or a block - like structure, etc., but not limited thereto. The fold angle of the vertical plate 11 is set to cooperate with the bottom plate 12, and the corner - to - corner setting of the two can enhance the stability of the installation. The connection between the vertical plate 11 and the bottom plate 12 can be integrally formed or welded, etc., but not limited thereto.

[0030] Reference Figure 3 , in some embodiments, the die cavity 31 is cylindrical, and the guiding die 4 is cylindrical and adapted to the die cavity 31. With such a setting, the guiding die 4 can be inserted into the die cavity 31 at any angle, and the installation is more convenient and fast.

[0031] In some embodiments, the length of the guiding die 4 is greater than or equal to the length of the die cavity 31. With such a setting, after the guiding die 4 is installed in the die cavity 31, a part of the guiding die 4 will be exposed or flush with the port of the die cavity 31. When the tin - plated copper wire 6 passes through the guiding die 4, the installation die 3 will not contact the tin - plated copper wire 6 and cause damage, ensuring the smoothness of the guiding of the tin - plated copper wire 6.

[0032] Reference Figure 1 and Figure 4 and Figure 5, in some embodiments, the positioning member 5 includes a first protrusion 51 and a second protrusion 52 installed on the top of the vertical plate 11 and located on both sides of the first card slot 111. A limiting groove 53 is formed on the surface of the first protrusion 51 close to the second protrusion 52. A sliding cavity 54 corresponding to the limiting groove 53 is formed on the second protrusion 52. A locking bar 55 is movably and guidingly installed in the sliding cavity 54. After the locking bar 55 is inserted into the limiting groove 53, its bottom abuts against the top of the clamping plate 2. It can be understood that the guiding setting of the locking bar 55 and the sliding cavity 54 adopts shaft-hole guiding cooperation. For example, the locking bar 55 can be round rod-shaped or square rod-shaped, etc., and the corresponding sliding cavity 54 and limiting groove 53 are also set to be circular or square, etc., but not limited thereto. With such a setting, after the clamping plate 2 is clamped on the vertical plate 11, the locking bar 55 is moved and inserted into the limiting groove 53. At this time, the bottom of the locking bar 55 abuts against the top of the clamping plate 2, thereby locking the clamping plate 2.

[0033] In some embodiments, in order to prevent the locking bar 55 from slipping out of the limiting groove 53, a limiting hole 56 is formed on the top of the vertical plate 11 on the side of the second protrusion 52 away from the first protrusion 51. A through hole 57 is formed at one end of the locking bar 55 away from the limiting groove 53. A fixing bolt 58 is embedded in the through hole 57. After the locking bar 55 is inserted into the limiting groove 53, the limiting hole 56 and the through hole 57 are vertically aligned, and then the fixing bolt 58 is inserted into the limiting hole 56. It can be understood that the cooperation between the fixing bolt 58 and the through hole can be shaft-hole embedding cooperation or thread cooperation, etc. In this way, the position of the locking bar 55 can be locked and will not slip out of the limiting groove 53, strengthening the stability of the limit on the vertical plate 11.

[0034] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
