Description

Technical Field

[0001] The invention relates to the technical field of copper wire tinning, and in particular to a uniform tinning device for copper wire. Background Art

[0002] Tinned copper wire refers to copper wire with a thin layer of metallic tin on the surface. Tinned copper wire is relatively soft and has good electrical conductivity. Compared with bare copper wire, it has stronger corrosion resistance and oxidation resistance, which can greatly extend the service life of weak current cables. Furthermore, the reason why the copper wire needs to be tinned is that when the copper wire is exposed to the air for a long time, it will be oxidized by the air to form a layer of verdigris, which has poor electrical conductivity and increases resistance.

[0003] The Chinese patent with the authorization announcement number CN115125465B discloses a copper wire tinning device for tinning wire processing, including a tinning furnace, a copper wire passing through the tinning furnace, a tinning furnace filled with a tin solution, a pumping device and a protective gas conveying device outside the tinning furnace, a top cover is provided at the top of the tinning furnace, a uniformly distributed fixed seat is fixedly connected to the bottom end of the top cover, a tinning tube is fixedly connected to the bottom end of the fixed seat, an infusion cavity is provided in the fixed seat, a through processing hole is provided in the tinning tube, one end of the infusion cavity is connected to the pumping device, and the other end is connected to the processing hole, one end of the pumping device is connected to the tin solution in the tinning furnace, the copper wire passes through the processing hole, and a power device is provided in the tinning furnace. The patent uses a high-temperature hose to reciprocately deform to form a suction action, so that the high-temperature hose sucks the tin solution in the tinning tube, so that the tin solution stirs the surrounding tin slag for rapid discharge, and avoids the tin slag affecting the rapid tinning of the copper wire and the tin solution.

[0004] In the above technical solution, when the copper wire just comes out of the tin-plating tube, the tin liquid on the surface of the copper wire has not completely cooled down. At this time, under the influence of gravity, the tin liquid will converge along the outer wall of the copper wire to the bottom of the copper wire, and finally make the thickness of the tin layer at the bottom of the copper wire greater than the thickness of the tin layer at other positions, affecting the quality of the tin plating of the copper wire. Summary of the invention

[0005] The present invention provides a uniform tinning device for copper wire, aiming to solve the technical problem in the related art that when the copper wire just passes through a tinning tube, the tin liquid on the surface of the copper wire has not been completely cooled. At this time, under the influence of gravity, the tin liquid will converge to the bottom of the copper wire along the outer wall of the copper wire, and finally make the thickness of the tin layer at the bottom of the copper wire greater than the thickness of the tin layer at other positions, thereby affecting the quality of the tinning of the copper wire.

[0006] The present invention discloses a uniform tinning device for copper wire, comprising: a tinning furnace and a plurality of tinning tubes arranged front and back; a plurality of processing modules corresponding to the tinning tubes are arranged in the tinning furnace; the processing modules include a bearing unit, a plurality of adsorption units and a cleaning unit; the bearing unit includes an outer cylinder horizontally sliding on the tinning furnace left and right, an inner cylinder coaxially rotating on the outer cylinder, a driving mechanism driving the inner cylinder to rotate is arranged on the outer cylinder, the copper wire passes through the inner cylinder and the axis of the copper wire is located directly below the axis of the inner cylinder; the plurality of adsorption units are circumferentially arranged in the inner cylinder, the adsorption unit includes a rotating unit coaxially ... The inner cylinder comprises a plurality of mounting posts which are axially spaced apart and adsorption blocks which are fixed on the mounting posts; the cleaning unit comprises a plurality of driving racks which are slidably connected to the inner cylinder through elastic parts and are transmission-coordinated with the mounting posts of each group of adsorption units, and a pushing part which is fixed on the outer cylinder, and the pushing part is located in the movement path of the driving rack to drive the driving rack to slide; the cleaning part is also comprised of a cleaning part which is fixed on the outer cylinder, a plurality of arc-shaped cleaning grooves which are spaced apart on the cleaning part along the left-right direction, and a collecting box which is arranged at the bottom of the cleaning part, and the cleaning grooves correspond one-to-one to the adsorption blocks in the left-right direction, and the shapes of the cleaning grooves and the adsorption blocks match.

[0007] Beneficial effect: When the copper wire just passes through the tin-plated tube, the tin liquid on the outer wall will gather to the bottom of the copper wire due to the influence of gravity. At this time, the inner cylinder continuously rotates on the outer cylinder, thereby driving multiple groups of adsorption units to rotate around the axis of the inner cylinder. When the adsorption block in each group of adsorption units rotates to the bottom of the copper wire, the top of the hemispherical surface of the adsorption block will contact the tin liquid gathered at the bottom of the copper wire, thereby adsorbing the excess tin liquid gathered at the bottom of the copper wire on the adsorption block, and the tin liquid will disperse around along the spherical surface of the adsorption block. At the same time, the cylinder will drive the outer cylinder and the inner cylinder to continuously reciprocate in the left and right directions, increase the contact area between the adsorption block and the tin liquid at the bottom of the copper wire, and ensure the comprehensive cleaning of the tin liquid gathered at the bottom of the copper wire. When the adsorption block rotates from the bottom to the top and enters the cleaning groove, the outer wall of the adsorption block will be completely in contact with the inner wall of the cleaning groove, and then the end of the push rod will abut against the push piece, forcing the adsorption block to rotate. In the process of passing through the arc-shaped cleaning groove, the adsorption block will also rotate around its own axis, thereby rubbing off the tin liquid on the outer wall of the adsorption block and cleaning the adsorption block.

[0008] Preferably, a mounting frame is provided on the side wall of the tinning furnace, the inner side of the mounting frame has a through hole, two sliding rods are fixedly mounted on the mounting frame, the sliding rods are horizontally arranged along the left and right directions, the outer tube slides with the sliding rods, a cylinder is fixedly mounted on the mounting frame, and the telescopic part of the cylinder is fixedly connected to the outer tube.

[0009] The effect is that the inner cylinder drives the adsorption unit to move back and forth continuously, thereby increasing the cleaning area of ​​the copper wire and ensuring the comprehensive cleaning of the tin liquid gathered at the bottom of the copper wire.

[0010] Preferably, the mounting frame is vertically slidably matched with the tinning furnace, and an adjusting rod is rotatably mounted on the top of the mounting frame, and the adjusting rod is threadably matched with the tinning furnace.

[0011] The effect is that the mounting frame is raised and lowered by rotating the adjusting rod, so that the distance between the upper end of the adsorption block rotated to the bottom and the bottom of the copper wire can be adjusted, the adsorption amount of the tin liquid gathered at the bottom of the copper wire can be controlled, and the copper wires of different diameters can be adapted.

[0012] Preferably, the driving mechanism includes a motor fixedly mounted on the outer cylinder, a driving gear fixedly mounted on the output end of the motor, a gear ring fixedly provided on the outer wall of the inner cylinder, a through opening is opened on the outer cylinder at a position corresponding to the driving gear, and the driving gear passes through the opening and meshes with the gear ring.

[0014] Preferably, the pushing member is an arc-shaped structure, and its width gradually increases along the rotation direction of the inner cylinder.

[0015] The effect is that when the push rod rotates to a position close to the upper part of the inner tube, the end of the push rod will abut against the push piece. As the width of the push piece increases, the push rod will be forced to slide, so that the mounting column drives the adsorption block to rotate.

[0016] Preferably, the adsorption block is a hemispherical structure, and the bottom plane of the adsorption block is fixedly connected to the end of the mounting column.

[0017] Preferably, the cleaning piece is in an arc-shaped structure and is coaxially arranged with the inner cylinder, and both ends of the cleaning groove are provided with blanking through holes communicating with the inner side of the cleaning piece.

[0018] The effect is that the tin material dropped on the cleaning groove will fall into the collection box through the material dropping through hole, thus completing the cleaning of the residue.

[0019] Preferably, a heating element is provided on the cleaning element to heat the cleaning tank, and a pipeline is connected to the collecting box to allow the tin liquid to flow back into the tin plating furnace.

[0020] Preferably, a liquid supply pipe is installed on the tinning furnace, the liquid supply pipe is connected to the multiple tinning tubes, and the liquid supply pipe is connected to a pump body.

[0021] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the copper wire just passes through the tin-plated tube, the tin liquid on the outer wall will gather to the bottom of the copper wire under the influence of gravity. At this time, the inner cylinder continuously rotates on the outer cylinder, thereby driving multiple groups of adsorption units to rotate around the axis of the inner cylinder. When the adsorption block in each group of adsorption units rotates to the bottom of the copper wire, the top of the hemispherical surface of the adsorption block will contact the tin liquid gathered at the bottom of the copper wire, thereby adsorbing the excess tin liquid gathered at the bottom of the copper wire on the adsorption block, and the tin liquid will disperse around along the spherical surface of the adsorption block. At the same time, the cylinder will drive the outer cylinder and the inner cylinder to continuously reciprocate in the left and right directions, increase the contact area between the adsorption block and the tin liquid at the bottom of the copper wire, and ensure the comprehensive cleaning of the tin liquid gathered at the bottom of the copper wire. When the adsorption block rotates from the bottom to the top, it will enter the cleaning groove, and the outer wall of the adsorption block will be completely in contact with the inner wall of the cleaning groove, and then the end of the push rod will abut against the push piece, forcing the adsorption block to rotate. In the process of passing through the arc-shaped cleaning groove, the adsorption block will also rotate around its own axis, thereby rubbing off the tin liquid on the outer wall of the adsorption block and cleaning the adsorption block.

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 9 As shown, a specific embodiment of a uniform tinning device for copper wire of the present invention comprises a tinning furnace 10, a tinning module and a processing module.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the tinning furnace 10 carries tin liquid inside, and the left and right side walls of the tinning furnace 10 are provided with through threading holes 11, and the threading holes 11 are used for copper wires to pass through. In this embodiment, the copper wire that has undergone preliminary treatment enters the tinning furnace 10 from the threading hole 11 on the left, is tinned by the tinning module, and then passes through the processing module to clean up the tin liquid gathered at the bottom of the copper wire. Finally, the copper wire passes through the threading hole 11 on the right, and then the copper wire is cooled and rolled up.

[0035] It is particularly noted that, in this embodiment, the diameter of the copper wire is greater than 10 mm.

[0036] The tinning modules are provided in multiple groups along the front-to-back direction, and the tinning modules can be set according to the number of copper wires. Each tinning module can allow one copper wire to pass through. In this embodiment, the tinning modules are provided in three groups, and in other embodiments, they can also be provided in two groups, four groups or even more.

[0037] Each group of tinning modules includes a tinning tube 12 fixedly mounted on the top wall of the tinning furnace 10. The axis of the tinning tube 12 is arranged horizontally in the left-right direction, and the copper wire passes through the tinning tube 12. A liquid supply pipe 13 is installed on the tinning furnace 10. The liquid supply pipe 13 is connected to multiple tinning tubes 12, and a pump body (not shown in the figure) is connected to the liquid supply pipe 13. The pump body can extract the tin liquid in the tinning furnace 10 and pump it into the tinning tube 12 through the liquid supply pipe 13, so as to tin the copper wire passing through the tinning tube 12. The tin liquid will be discharged from the openings on both sides of the tinning tube 12 and return to the tinning furnace 10 to achieve circulation.

[0038] like Figure 3 As shown, there are multiple groups of processing modules arranged along the front-to-back direction. The processing modules are arranged on the right side of the tinning modules, and one group of processing modules is arranged correspondingly on the right side of each group of tinning tubes 12 .

[0039] The processing module includes a mounting unit, a carrying unit, an adsorption unit and a cleaning unit.

[0040] like Figure 3 and Figure 4 As shown, the mounting unit includes a mounting frame 20 that is slidably mounted on the right side wall of the tinning furnace 10. The mounting frame 20 is a square frame with a through hole on the inside to ensure that the copper wire can pass through the through hole on the inside, and the through hole on the inside of the mounting frame 20 corresponds to the wire threading hole 11 on the right side of the tinning furnace 10, thereby facilitating the transportation of the copper wire.

[0041] An adjusting rod 21 is rotatably installed on the top of the mounting frame 20, and the adjusting rod 21 is threadedly matched with the tinning furnace 10, so that when the adjusting rod 21 is rotated, the mounting frame 20 can be controlled to slide up and down on the side wall of the tinning furnace 10, so as to adjust the distance between the adsorption unit and the bottom of the copper wire, control the amount of tin liquid adsorbed at the bottom of the copper wire, or adapt to copper wires of different sizes.

[0042] like Figure 4 , Figure 5 and Figure 6 As shown, the bearing unit includes a slide rod 22, an outer cylinder 30, an inner cylinder 40 and a driving mechanism.

[0043] The slide bar 22 is fixedly mounted on the mounting frame 20. The slide bar 22 is arranged horizontally in the left-right direction. Two slide bars 22 are arranged in front and rear. The two slide bars 22 are arranged parallel to each other. The outer cylinder 30 is slidably mounted on the two slide bars 22 in front and rear, and can slide back and forth along the axial direction of the slide bars 22. The mounting frame 20 is fixedly mounted with a cylinder 23. The telescopic part of the cylinder 23 is fixedly connected to the outer cylinder 30, so that the outer cylinder 30 is driven by the cylinder 23 to slide back and forth continuously in the left-right direction.

[0044] The inner cylinder 40 is rotatably mounted inside the outer cylinder 30, the inner cylinder 40 is coaxially arranged with the outer cylinder 30, and the inner cylinder 40 rotates inside the outer cylinder 30 through a driving mechanism. The driving mechanism includes a motor 31 fixedly mounted on the top of the outer cylinder 30, a driving gear 32 is fixedly mounted on the output end of the motor 31, a gear ring 33 is fixedly mounted on the outer wall of the inner cylinder 40, and an opening that passes through the outer cylinder 30 at a position corresponding to the driving gear 32 is provided, and the driving gear 32 meshes with the gear ring 33 through the opening, so that the motor 31 drives the driving gear 32 to rotate, thereby driving the gear ring 33 and the inner cylinder 40 to rotate.

[0045] The copper wire passes through the inner side of the inner cylinder 40. It should be noted that the axis of the copper wire is located directly below the axis of the inner cylinder 40, so that when the inner cylinder 40 drives the adsorption unit to rotate, the adsorption unit can absorb excess tin liquid when it contacts the tin liquid at the bottom of the copper wire.

[0046] like Figure 6 and Figure 7 As shown, the adsorption units are arranged on the inner wall of the inner cylinder 40, and multiple groups of adsorption units are arranged along the circumference of the inner cylinder 40. In this embodiment, 3 groups of adsorption units are arranged. In other embodiments, there may be 4 groups, 6 groups or even more.

[0047] Each group of adsorption units includes a plurality of mounting columns 41 vertically rotatably mounted on the inner wall of the inner cylinder 40, and the plurality of mounting columns 41 are spaced apart along the axial direction of the inner cylinder 40. An adsorption block 42 is fixedly mounted on one end of the mounting column 41 away from the inner cylinder 40. In this embodiment, the adsorption block 42 is a hemispherical structure, and the plane at the bottom of the adsorption block 42 is fixedly connected to the end of the mounting column 41.

[0048] It should be noted that the structure of the adsorption block 42 is not limited thereto, and may also be other structures such as a spherical or conical shape.

[0049] When the copper wire just passes through the tin-plated tube 12, the tin liquid on the outer wall will gather to the bottom of the copper wire due to gravity. At this time, the inner cylinder 40 continuously rotates on the outer cylinder 30, thereby driving the multiple groups of adsorption units to rotate around the axis of the inner cylinder 40. When the adsorption block 42 in each group of adsorption units rotates to the bottom of the copper wire (such as Figure 6 ), the top of the hemispherical surface of the adsorption block 42 will contact the tin liquid gathered at the bottom of the copper wire, so that the excess tin liquid gathered at the bottom of the copper wire will be adsorbed on the adsorption block 42, and the tin liquid will be dispersed around along the spherical surface of the adsorption block 42. At the same time, the cylinder 23 will drive the outer cylinder 30 and the inner cylinder 40 to continuously reciprocate in the left and right directions, increasing the contact area between the adsorption block 42 and the tin liquid at the bottom of the copper wire, ensuring the comprehensive cleaning of the tin liquid gathered at the bottom of the copper wire.

[0050] It is particularly noted that when the adsorption block 42 rotates to just below the copper wire, there is a certain gap between the upper end of the adsorption block 42 and the copper wire, which only ensures that the upper end of the adsorption block 42 is in contact with the tin liquid gathered at the bottom of the copper wire, but the adsorption block 42 will not contact the copper wire, avoiding damage to the tin layer on the copper wire.

[0051] By rotating the adjusting rod 21 to control the lifting of the mounting frame 20, the distance between the upper end of the adsorption block 42 rotated to the bottom and the bottom of the copper wire can be adjusted, and the adsorption amount of the tin liquid gathered at the bottom of the copper wire can be controlled.

[0052] The adsorption force of the adsorption block 42 on the tin liquid is smaller than that of the copper wire, so that the adsorption block 42 can only adsorb the excess tin liquid gathered at the bottom of the copper wire, and avoid the adsorption block 42 adsorbing the tin liquid normally attached to the copper wire. The material of the adsorption block 42 can be stainless steel, ceramic, etc.

[0053] The cleaning unit comprises a transmission component and a cleaning component.

[0054] like Figure 7 , Figure 8 and Fig. 9 As shown, the transmission assembly includes a transmission gear 43 fixedly mounted on the outer wall of the mounting column 41, and each group of adsorption units is provided with a driving rack 44 slidably mounted on the inner wall of the inner cylinder 40, and the driving rack 44 can slide along the axial direction of the inner cylinder 40, and the end of the driving rack 44 is connected to the inner cylinder 40 through a spring 45. Each driving rack 44 is meshed and connected with the transmission gear 43 in each group of adsorption units. When the driving rack 44 slides along the axial direction of the inner cylinder 40, it can simultaneously drive the mounting column 41 in each group to rotate together.

[0055] A push rod 46 is fixedly mounted on the moving end (left end) of each driving rack 44 , and the push rod 46 extends to the outside of the inner cylinder 40 .

[0056] A push piece 47 is fixedly installed at the left side of the outer cylinder 30 near the top. The push piece 47 is located on the rotation path of the push rod 46. The push piece 47 is an arc-shaped structure, and its width gradually increases along the rotation direction of the inner cylinder 40 (such as Fig. 9 ). Thus, when the push rod 46 rotates to a position close to the upper part of the inner cylinder 40, the end of the push rod 46 will abut against the push piece 47. As the width of the push piece 47 increases, the push rod 46 will be forced to slide to the right, so that the mounting column 41 drives the adsorption block 42 to rotate. At this time, the spring 45 will be compressed, and when the push rod 46 is separated from the push piece 47, the spring 45 will drive the drive rack 44 to reset.

[0057] like Figure 6 and Figure 8 The cleaning assembly includes a cleaning member 50 disposed inside the inner cylinder 40, and the cleaning member 50 is an arc-shaped structure and is coaxially disposed with the inner cylinder 40. The cleaning member 50 is located near the top of the inner cylinder 40, and the cleaning member 50 is fixedly connected to the outer cylinder 30 through a connecting frame.

[0058] A plurality of cleaning grooves 51 are arranged at intervals along the left and right directions on the cleaning member 50, and each cleaning groove 51 corresponds to the adsorption block 42 in the left and right directions. The cleaning groove 51 is close to the top position of the cleaning member 50 and is located on the movement path of the adsorption block 42. The cleaning groove 51 is an arc-shaped structure, and the cross section of the cleaning groove 51 is a semicircular structure that fully matches the adsorption block 42.

[0059] Therefore, when the adsorption block 42 rotates from the bottom to the top, the tin liquid on the adsorption block 42 cools and adheres to the outer wall of the adsorption block 42, and then the adsorption block 42 enters the cleaning groove 51, and the outer wall of the adsorption block 42 is completely in contact with the inner wall of the cleaning groove 51, and then the end of the push rod 46 abuts against the push piece 47, forcing the adsorption block 42 to rotate. In the process of passing through the arc-shaped cleaning groove 51, the adsorption block 42 will also rotate around its own axis, thereby rubbing off the tin liquid on the outer wall of the adsorption block 42, thereby cleaning the adsorption block 42.

[0060] A collection box 53 is detachably mounted at the bottom of the cleaning member 50, and the front and rear ends of the cleaning groove 51 have material-dropping through holes 52 that are connected to the inner side of the cleaning member 50. Tin material dropped on the cleaning groove 51 will pass through the material-dropping through holes 52 and fall into the collection box 53, completing the cleaning of the residue. After the work is completed, the residue in the collection box 53 can be recycled.

[0061] In another embodiment, the cleaning member 50 can clean the tin liquid attached to the adsorption block 42 by heating. This embodiment is not shown in the figure.

[0062] A heating element is provided on the cleaning piece 50, which can be specifically an electric heating wire, which can heat the cleaning groove 51 so that the cleaning groove 51 maintains a certain temperature. When the adsorption block 42 enters the cleaning groove 51, the heat of the cleaning piece 50 will be transferred to the adsorption block 42, so that the cooled tin layer on the adsorption block 42 will melt again and flow into the cleaning groove 51, and then fall into the collecting box 53 through the blanking holes 52 on both sides of the cleaning groove 51, and the collecting box 53 is connected with a pipe, and the discharge end of the pipe can discharge the tin liquid into the tin plating furnace 10, so that the tin liquid flows back into the tin plating furnace 10 to realize circulation.

[0063] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
